Problems solved by technology
The tractor with fixed jaw structure is difficult to respond in time to the pulse-like change in the length of the profile, and thus cannot guarantee the stability of the traction force on the workpiece
At the same time, the vibration of the forging machine when processing the workpiece is also transmitted through the workpiece and the fixed jaw, which will cause certain interference to the main body of the tractor and affect the control of the tractor
It is also difficult to guarantee the forging quality of the final profile products

The invention discloses a novel traction machine jaw device. The jaw device comprises a lower jaw plate, the lower jaw plate is fixed to a traction machine body, a guide column is arranged on the lower jaw plate, an upper jaw support is arranged on the guide column, the upper jaw support is driven by a driving device, an upper jaw is arranged on the upper jaw support, the upper jaw support drivesthe upper jaw to move downwards along the guide column and clamp a workpiece together with the lower jaw, the end part of the lower jaw is connected with one end of a connecting rod, the connecting rod penetrates through a spring baffle fixed on the lower jaw plate, a compressible spring is arranged between the other end of the connecting rod and the spring baffle, and a displacement detection device capable of detecting the displacement of the connecting rod is arranged on the connecting rod. According to the jaw device, the workpiece can be reliably clamped, and the stable and reliable traction force can be provided.
Description
technical field [0001] The invention relates to the technical field of metal plastic processing, in particular to a novel tractor jaw device. Background technique [0002] The length of thin-walled metal profile workpieces with small cross-sections increases continuously during the process of being shaped and processed by high-frequency forging hosts. The forging process of the forging host is a high-frequency working process, and the frequency is generally not less than 10Hz. Therefore, the profile size also shows a pulse-like high-frequency growth, rather than a continuously changing smooth growth curve. The traction machine with fixed jaw structure is difficult to respond to the pulse-like growth of profile length in time, and thus cannot guarantee the stability of the traction force on the workpiece. At the same time, the vibration of the forging machine when processing the workpiece is also transmitted through the workpiece and the fixed jaw, which will cause certain ...
