Forging machine is a metal and mechanical cold working equipment.
It only changes the outer shape of the metal.
Forging machine includes:
(1) Forging machine stamping formwork
The stamping formwork is the most typical component of forging machine tool, and it has achieved standardization and specialization at the earliest.
Pressing, blanking, drawing, slitting and other stamping processes on the machine press are inseparable from the stamping die.
The working part of the stamping die has a punch and a die mounted on the stamping formwork.
Different stamping processes require different punches and dies, but the same stamping dies can be used.
The stamping formwork consists of an upper formwork, a lower formwork, a guide post and a guide sleeve.
A series of products for presses of different specifications and models have been developed, and stamping dies of medium size and below have been standardized.
(2) Forging machine brake
In the functional components of forging machine tools, the friction clutch-brake for machine tool presses is the first to be developed in terms of the maturity of its development, production and use.
The friction clutch-brake is an important part of the main drive of the press machine. Its performance directly affects the usability, safety, reliability and start-up rate and maintenance of the machine.
According to the structure of the friction clutch-brake, there are:
- Combined friction clutch-brake
- Separate friction clutch-brake
According to the working status of the friction, there are:
- Dry friction clutch-brake
- Wet friction clutch-brake
According to the friction clutch-brake control system, there are:
- Pneumatic friction clutch-brake
- Hydraulic friction clutch-brake
(3) Forging machine photoelectric safety protection device
The photoelectric safety protection device is provided with an invisible infrared light curtain in a protection area between the operator of the forging machine and the dangerous working area.
Once a certain part of the operator enters the protection zone to block the light curtain, the control system outputs a signal to the safety actuator of the forging machine to stop the forging machine and prevent dangerous actions.
It can be seen that the photoelectric safety protection device itself does not directly protect the operator, it only sends a signal to the machine tool to stop the dangerous action before a safety accident may occur.
Therefore, strictly speaking, the photoelectric safety protection device should be called the photoelectric safety protection control device.
Photoelectric safety protection devices are usually divided into reflective and through-beam types.
The reflective photoelectric safety protection device is composed of controller, sensor and reflector.
The light curtain is emitted by the sensor and reflected back to the sensor through the reflector for the reception.
The through-beam photoelectric safety protection device is composed of controller, transmitting sensor and receiving sensor.
The light curtain is emitted by the transmitting sensor and received by the receiving sensor.
(4) Forging machine cam controller
The cam controller is an important part of the electrical control system of the press machine.
The method of processing the logical relationship of the working mechanism is usually to allocate 360° of the crankshaft rotation, and to formulate a working cycle diagram of the machine press, and control the operation of each working mechanism.
The cam controller is the actuator that distributes the angle of rotation of the crankshaft.
The cam controller is mounted on a shaft that rotates synchronously with the crankshaft, and the working mechanism sequentially produces a prescribed action to complete a duty cycle of the press machine.
(5) Forging machine automatic feeding device
There are various automatic feeding devices in the forging machine.
Here, it refers to an automatic feeding device for sheet metal processing, such as an open press, a closed press, a multi-station press, a high-speed press, or a single press or a stamping automatic line.
The automatic feeding device generally consists of three parts: material rack and an unwinding leveling mechanism, pneumatic clamp type feeding mechanism, and waste winding material rack.
The rack and unwinding leveling mechanism have three functions which are supporting coiling, unwinding and leveling.
The unwinding mechanism loosens the coil material in a freely suspended state to reduce the pulling force of the feeding mechanism during the feeding process, which is beneficial to improve the feeding precision.
The leveling mechanism applies multiple rollers to the coil material after the unwinding, so that the sheet is corrected before stamping, which is beneficial to improve the precision of the product.
The pneumatic clamp feeding mechanism uses compressed air as the power to control the opening and closing and reciprocating movement of the clamp to complete the feeding of the sheet.
The reciprocating stroke is steplessly adjustable to accommodate different feed length requirements.
The scrap rewinding rack winds the stamped waste strip.
This part is not required if the scrap material is cut and recycled during stamping.
