Press shears nb5222 are used for high-quality cutting of rolled products - shaped, sheet, and long products. The devices also allow you to make various notches.

Combination shears may be called press shears provided they are equipped with a punching press.

The technical characteristics of the NG5222 model provide for the presence of four mechanisms that form the basis of the equipment:

• Mechanism for cutting high-quality metals;
• For cutting metal sheets;
• Hole making system;
• Device for cutting grooves.

What do you need to know about similar press shears combined models NG5222?

1. All of these mechanisms are assembled in a single frame and are equipped with a common drive.
2. The sliders of sheet and grade shears use a lever mechanism to carry out control.
3. The hole-punching mechanism of the device has two types of control - lever and pedal.
4. The main technical characteristics are regulated by the state standard.
5. Performing cutting with scissors allows you to achieve the most economical method of dividing rolled products into the corresponding required workpieces.
6. When using a cutter, it is important to avoid double cutting. To do this, it is necessary to maintain a certain depth of insertion of the knives into the metal workpiece. It should not exceed V4 from the height of the cut section. This is especially important when processing ductile metal or workpieces that have been specially heated to a high temperature.
7. To prevent the formation of cracks on the end sides of the workpieces being processed, which may be due to the brittleness of certain types of steel, the workpiece should be heated.
8. The cold method is used to cut carbon steel, the percentage of carbon content in which does not exceed 0.5 percent.
9. The resulting quality of the workpiece cut is directly influenced by the speed at which the knife enters the metal. If cutting carbon steel is required, higher speeds are used. Alloy steel requires more delicate cutting, so the speed is set to lower.
10. Based on the peculiarities of processing different types of metals, it is reasonable to equip the press machine with two-speed electric motors in order to control and regulate the speed of work.

Features of the NG5222 machine

Among the combined shear presses on the market, the new generation combined devices have gained the most popularity. The NG5222 model provides solutions to many production issues.

The main features are the ability, with minimal manipulations with the machine, to perform a number of tasks and combine the operations performed:

• Punch holes and grooves;
• Cut circles, corners, squares;
• Cut strips;
• Manufacture I-beams and channels.

Thus, the NG machine provides wide functionality of the shear press and the cost-effectiveness of rolled products when processed on just one device.

Combined press shears NV5222, N5222a, NV5221, NB5224 are the predecessor of the more modern and improved press shears NG5222.

Machine Applications

Press shears NG perform several different tasks:

• Cutting of rolled metal products - long, shaped, strip;

Nuances of the design of NG machines

NG machines have found wide application in various areas of production. This is due to the wide functionality and impressive technical characteristics of the machines. Therefore, you should get acquainted with their use and purpose in more detail. But to do this, you need to understand the design elements of the NG.

Combination press scissors ensure the performance of several different operations, avoiding preliminary changes to the device settings. This is possible thanks to four working zones. Work can be carried out in any sequence. There is no need to change tools. This is how fast, economical and productive processing of workpieces is achieved.

What should you know about the design of this machine?

1. The bed consists of a pair of metal sheets - rear and front. They are connected to the base by welding.
2. Four borings in the frame are used for mounting section drives and drive shafts on NG machines.
3. The drives of the punching and sheet metal sections come from an electric motor through gear and V-belt transmissions to an eccentric shaft.
4. The levers of the cutting devices of the machines are directly connected to the sliders of the sheet sections due to traction.
5. The sliders of the punching sections are balanced due to special spring equalizers.
6. The mechanism designed for cutting corners, squares, and metal circles consists of 2 plates. One is movable, the other is stationary. The movable plate is fixed in the socket of the slider of the sheet section. The fixed part is placed in the frame socket and fixed using L-shaped springs.
7. Notching and sheet units include fixed and movable knives in the design - 3 and 2 units, respectively.
8. The press shears provide three workstations that can be serviced by one operator.
9. The electrical circuit has been modernized if we compare the NG5222 and the combined shear press N5222a. This electrical circuit allows the shear press to operate on single and continuous strokes.
10. The control of the press scissors is pedal-based and push-button.

The combined design of the machine ensures its multitasking with maximum efficiency and economy. NG5222 has found its niche in the shear press market and confidently maintains its leading position.

Excellent technical characteristics, attractive price and high performance indicators make the NG5222 machine one of the most preferred devices. The price of press scissors starts from $1000. Quite reasonable cost for such machine parameters.

Operation of the HB5222 press

Kinematic diagram

1 – gear shaft, 2 – flywheel, 3 – electric motor, 4 – gear wheel,

5 – connecting rod, 6 – shaft, 7 – balancer, 8 – press slide, 9 – electromagnet,

10 – slider of the strip section.

The shear press is driven from an electric motor (3) through a V-belt transmission, a flywheel (2) and a single-stage gear transmission (1, 4) to an eccentric shaft (6). The gear pair (1.4) is straight-toothed, cylindrical. The movement is transmitted to the slider (10) of the strip section through the connecting rod (5), to the slider (8) of the press for punching holes through the balancer (7) and the sinking stone. Switching on and off the actuators is carried out through a system of levers connected on one side with a connecting rod and a sinking stone, and on the other hand with electromagnets (9).

Place the switch in the position: “band strip section” or in the “hole-punching section” position.

1. Hole punching:

Attach the punch and die in the corresponding slots. Then, turning the centering mechanism handle, lower the punch into the die and insert the die holder body so that a uniform gap is maintained between the die and the punch.

Attach the die holder body to the frame and check the gap again.

Depending on the thickness of the material being punched, align the puller body by loosening the nuts and locknuts, and by rotating the screws, insert the puller body with a gap of 1...2 mm from the plane of the sheet.

Tighten the nuts and locknuts. Installing the puller body skewed is not permissible.

To punch holes along the cores, use the centering mechanism. Lower the punch with the handle and align the core on the workpiece with the punch core.

1. Variety strip section:

To cut shaped steel, install the appropriate tool in the socket of the slider and frame. Align the stop plate to the appropriate angle (90°, 45°) along the guide lines and secure it. Install replacement clamps. Insert the rolled piece into the tool socket and align it either according to the markings or against the cutting stop of the workpieces, the size of which you have previously set. Do not cut a strip that has oil stains on its surface.

When the scoring device is operating, the gap between the knives is set by spacers under the supporting surfaces and depends on the thickness of the material being cut. The knives of the scoring device must fit snugly to the supporting surfaces, must be well secured and dry.

Blow compressed air into the frame cavity under the strip slide to remove accumulated scale or remove it with a scraper.

For safety, the shear presses are equipped with guards for all rotating parts of the scoring device and the hole-punching area.

When working with scissors:

• do not cut or punch holes in profiles and materials larger than those indicated in the technical specifications at δв = 500 N/mm²;
• do not remove the barriers;
• do not work on the strip section without clamps;
• Do not adjust the shears while the electric motor is on.

Overall dimensions, weight, as well as other design parameters available in the description fully comply with the requirements of GOST 7355. The manufacturer has the right to make minor changes to the design that do not lead to a deterioration in the operational capabilities of the scissors. These changes are reflected in the product passport.

Composition of units and principle of their operation

Scissors model NG5222 include:

1. AC drive motor;
2. V-belt transmission;
3. receiving shaft;
4. flywheel;
5. eccentric shaft;
6. main slider drive connecting rod;
7. balancer of the rolled section cutting section;
8. punching press balancer;
9. back stop;
10. bed.

The unit is controlled using a system of levers that are kinematically connected to two control electromagnets. When the drive rods are switched into the corresponding slots, either the punch of the punching press moves or the balancer of the rolling cutting section swings. The scissors can operate in single and continuous stroke modes. It should be taken into account that, due to the absence of an engagement clutch, the stop of the slide occurs within a certain time.

The cutting tool is fastened in special grooves in the slide. Installation of the punching punch is carried out in the punch holder, while the matrix is ​​installed on the punching table.

The scissors passport also includes a list of necessary tools and accessories, including handles for fixing the table and centering device, sets of punches and knives, a receiving tray and a number of others. A tool for cutting special rolled profiles is also available as an option.

This is how scissors work. The torque from the switched-on electric motor is transmitted by a V-belt transmission to the flywheel, which compensates for possible fluctuations in the shaft speed due to force overload of the shears. Next, using a spur gear, the movement is transmitted to the eccentric shaft, on which a connecting rod is mounted to drive the slider of the section cutting mechanism and the rod of the swinging balancer, which controls the movement of the punching press. If it is necessary to punch holes, the corresponding control electromagnet is turned on, which rotates the multi-link lever and produces a translational movement of the punch downwards, while a continuously swinging balancer is responsible for returning the punch to its uppermost position. To cut long or round rolled metal, a second electromagnet is turned on. He turns the double lever, which in turn pushes the connecting rod down. It imparts a rocking motion to the slider, and at the same time fixes the back stop, which is responsible for the accuracy of the cut, in a certain position. The shears are turned on/off using a pedal: after completing the technological operation, the operator releases the pedal and the drive stops in the required position. After this, it is possible to install the next workpiece to be processed into the working area of ​​the scissors. There is also a push-button station for controlling the scissors when they perform the hole-punching operation.

Technological capabilities of scissors

The range of application of the equipment under consideration can be expanded by installing a non-drive modular roller conveyor type MRP. In particular, it is possible to cut rods of round or square cross-section with a length of up to 3...6 m. The supplied basic set of tools and accessories includes:

The combined lubrication system used provides for the operation of the shears both inside and outside the production premises, and there is no need to supply compressed air to the installation site of the shears. The passport contains the necessary information about installing the scissors on a permanent basis, and the conditions for their shelter from adverse atmospheric influences.
