COLD FORMING PRESS FOR WASHER PRODUCTION

 

FEATURES OF EQUIPMENT FOR PRODUCTION OF WASHERS AND COMPLEX PARTS

Why do so many partners from around the world choose our equipment?

The first feature. Construction equipment and technical specifications of its components

1. The principle of operation of the press:

The equipment is a mechanical press with CNC for the production of metal washers by cold stamping method. Its principle of operation is based on the conversion of rotary motion to drive reciprocating movement of the slide. Working part of the press is a rubber stamp, it consists of two halves. Upper movable (punch) and lower fixed (matrix). The matrix is secured to the table, to the punch press ram. The structure of the press mechanism includes an automatic feeding of metal into the work zone, as well as a calibration device for imparting a rolled sheet more rectilinear appearance, conveyor to remove metal scrap from the work area. Main engine of a press is equipped with oil cooler for protection against overheating. Press control is performed through touch-screen monitor. The monitor is mounted in a metal housing.

Code HS TS: 8462 10 100 9

2. Form factor:

The housing is designed according to the type of box and has good stiffness. Deformation during forming is minimized. Improved accuracy of bottom dead center. On each side of the body there are holes for easy installation of additional equipment.

3. Drive:

The drive is completely hidden inside the body. The slide is driven by a servo gear and eccentric shaft, sealed by toggle joints.

4. Safety brake:

Dry friction pads are applied. Once the main engine is running, the brake can be activated automatically if for 30 seconds there were no operations, safety brake automatically disconnects the electricity supply to the main engine and immediately stops the machine.

5. Additional equipment:

At the request of the customer on this mechanism different automation equipment can be set. For more information, please contact the technical staff of our company.

 

The second feature. Servomotor Kingservo, Taiwan

Features of servomotor Kingservo

This mechanism is the latest model of servomotor. Compared with traditional presses with switches, there is a slide body to the bottom dead center, which improves the accuracy of the molding. The rate of convergence of the mold in such small presses is low, that will extend the service life and reduce the impulse and noise at the time of contact. Thus, this mechanism is particularly suited to forging, cutting plates and cold forming.

Servomotor with management through negative feedback allows precisely control the motion parameters. Important characteristics are the dynamics of the servo motor, fluidity, energy efficiency. Press for cold heading of washers and products is equipped with servo drive, made in Taiwan.


 

The third feature. Possibility of changeover for heading of products of a rod (wire coil) and from a sheet of steel

EQUIPMENT FOR WASHERS COLD PRODUCTION idealy match for heading washers and flat products. A special feature is the ability to heading production of flat form of metal rod and sheet metal.

Molds are made from high-quality metal brand SKD-11 and S45C. The cost of the tool set is comparable to the average cost of foreign cars.

The fourth feature. Cost of consumption of raw

cold heading of washer
metal sheet stamping

Possibility of lateral movement (left / right) of the feeder creates the possibility of the most effective use of metal blanks.

This also minimizes the amount of waste produced.

 

The fifth feature. The heading of products of complex shape

The technology of production of complex shapes requires multi-position equipment. Furthermore, the technology may vary depending on the method of heading washers – made of rod or sheet metal.

The heading of products of rod requires the use of equipment for pre-heading (cutting machine for cutting and flattening the blank) and cold forging equipment (3-Position cold heading machine with servo drive).

The sixth feature. Energy saving and safety in operation

and other modern laws and safety standards when dealing with the press, which have been designed to provide comfort and safety of the worker. The following equipment is protective:

1) Emergency stop device.
2) Devices for the motor overload protection.
3) Safe circuit for bimanual operation.
4) Means to prevent too low speed (variable speed).
5) Devices for control of errors.
6) The photoelectric protective equipment. (Special accessory)
