Transfer processing unit for internally toothed lock washers

Abstract

The invention relates to the field of part machining and particularly discloses a conveying machining device for internal tooth locking washers. According to the device, a calibration stamping mechanism is adopted, and before stamping of the internal tooth locking washers is started, the positions of the internal tooth locking washers can be calibrated through driving levers and a rotatable extending-and-contracting rod; and it is guaranteed that a stamping portion of each internal tooth locking washer can be subjected to stamping precisely, furthermore, stamping quality of the internal tooth locking washers is improved, and the stamping defective rate of the internal tooth locking washers is lowered. By means of the conveying device, the internal tooth locking washers can be aligned with a stamping head and jacking rods, and stamping efficiency of the internal tooth locking washers is improved.

Description

technical field [0001] The invention belongs to the field of part processing, and in particular relates to a transmission processing device for internal tooth lock washers. Background technique [0002] The internal tooth lock washer is a flat thin-walled part, which can be used between the nut and the bolt, which can effectively prevent the spring and the bolt from loosening. At the same time, the internal tooth lock washer is smaller than the ordinary spring washer, and the fastener is evenly stressed. , It is also reliable to prevent loosening; at the same time, the internal tooth lock washer is also a simple locking retaining ring, which can be used on the shaft. At this time, the teeth on the inner side of the washer have the function of preventing retreat. [0003] The stamping process of the internal tooth lock washer includes two processes. First, the sheet blank is stamped into a blank with the prototype of the internal tooth lock washer, and then the stamping part ...

Problems solved by technology

[0003] The stamping process of the internal tooth lock washer includes two processes. First, the sheet blank is stamped into a blank with the prototype of the internal tooth lock washer, and then the stamping part on the blank is stamped. When stamping the inner tooth lock washer, the stamping head is located on the upper surface of the stamping part of the internal tooth lock washer, and at the same time, the ejector rod needs to be in contact with the lower surface of the stamping part of the internal tooth lock washer, and then the stamping head is pressed against the stamping part of the internal tooth lock washer For stamping, when the internal tooth lock washer is directly placed on the ejector pin, it is difficult for the stamping part to face the stamping part of the internal tooth lock washer; Misalignment will lead to the production of defective internal tooth lock washers, which will greatly reduce the processing efficiency of internal tooth lock washers and increase the processing cost of internal tooth lock washers
