A jaw device for a roll forging machine

Abstract

The invention relates to the relavent technical field of rolling forging machines, in particular to a clamping opening device of a rolling forging machine. A cylinder is included, and a positioning protective plate is in screwed connection with the surface of the cylinder; a positioning rod is welded to the surface of the cylinder; a clamped connection groove is arranged in an installing plate, and an elastic clamping ring is connected in the clamped connection groove in a clamped manner; a pneumatic groove is arranged in a pneumatic supporting base; a threaded plate is welded to the surface of the pneumatic supporting base; and a threaded groove is arranged in an installing base, and the threaded plate is in screwed connection in the threaded groove. The clamping opening device of the rolling forging machine has the beneficial effects that when machined pieces in different types need to be machined, the pneumatic supporting base is moved in a screwing manner, so that the threaded plate disengages from the threaded groove, and the pneumatic supporting base can be taken down at the moment; the structure is simple, and the pneumatic supporting base can be disassembled and installed conveniently; then a proper pneumatic supporting base is in screwed connection with the surface of the installing base through the threaded plate, and then the machined pieces in different types can bemachined; and the application range is wide, the using cost is lowered, and the clamping opening device of the rolling forging machine is suitable for popularization.

Description

technical field [0001] The invention relates to the related technical field of a roll forging machine, in particular to a nip device of a roll forging machine. Background technique [0002] The roll forging machine is mainly used for pre-forging of forgings, and can also be used for final forging. It can also be combined with other forging equipment such as: air hammer, friction press, screw press, crank press, etc. to form a forging production line, equipped with a manipulator or The automatic device can realize the automation of roll forging production. The roll forging machine clamps and fixes the workpiece through the clamping device, but the general clamping device still has the following disadvantages in actual use: [0003] 1. Generally, the clamping device adopts a pneumatic structure to clamp and fix the workpiece. The clamping device needs to be connected to the control terminal through multiple sets of wires. Multiple sets of wires are connected to the side ends o...

Problems solved by technology

[0003] 1. Generally, the clamping device adopts a pneumatic structure to clamp and fix the workpiece. The clamping device needs to be connected to the control terminal through multiple sets of wires. Multiple sets of wires are connected to the side ends of the clamping device. Phenomena such as short circuit occur, which affects the quality of the jaw device, and the arrangement of multiple sets of wires is disorderly, which is not convenient for the use of the jaw device and the maintenance of the jaw device;

[0004] 2. When the workpiece is clamped and fixed by the jaw device, the workpiece needs to be transferred to the point to be processed, and then one side surface of the workpiece is processed. After the processing of the one side surface of the workpiece is completed, the workpiece needs to be removed Next, rotate the workpiece, and finally fix the workpiece again, and then process the other side surface of the workpiece. The operation is complicated, time-consuming and laborious, and affects the processing efficiency of the workpiece;

[0005] 3. The general clamping device corresponds to one kind of processing workpiece, and cannot clamp and fix different types of workpieces. When processing different types of workpieces, the entire clamping device needs to be disassembled and replaced. The operation is complicated and time-consuming It is laborious, and the clamping part of the jaw device cannot be directly replaced, which increases the cost of use, reduces the efficiency of workpiece processing, and has poor use effect
