Embodiment Construction

[0023] like figure 2 As shown, a cotter pin crimping production equipment, the equipment includes a base plate and a driving device 1 installed on the base plate, a feeding device 2, a positioning forming device 3 and a crimping device 4. The drive device 1 comprises a drive shaft 11 . The driving shaft 11 is arranged horizontally and rotates in a circumferential direction. The output end of the driving shaft 11 is connected to the positioning forming device 3 and drives the positioning forming device 3 to rotate around the driving shaft 11 . There are at least three crimping devices 4 . The crimping device 4 is distributed along the circumferential direction of the positioning forming device 3 , the positioning forming device 3 drives the crimping device 4 to rotate through the gear assembly 5 , and the positioning forming device 3 and the crimping device 4 rotate in opposite directions. The feeding device 2 is driven to be positioned at the side of the positioning forming...

Abstract

The invention relates to the field of hardware production and manufacturing, in particular to a cotter spring pin curling production method and equipment thereof. The cotter spring pin curling production equipment comprises a driving device, a feeding device, a positioning and forming device and curling devices; wherein the driving device comprises a driving shaft; the driving shaft is horizontally arranged and circumferentially rotates; the output end of the driving shaft is connected with the positioning and forming device and drives the positioning and forming device to rotate around the driving shaft; the curling devices are distributed in the circumferential direction of the positioning and forming device; the positioning and forming device drives the curling devices to rotate througha gear assembly; the positioning and forming device and the curling devices are opposite in rotating directions; the feeding device is used for placing raw materials into the positioning and formingdevice; and raw materials are fed to a forming rotary disk, and extruded by the forming rotary disk and the curling devices to form a cotter spring pin. The cotter spring pin curling production methodand the equipment thereof have the technical effects that the raw materials do not need to wait from feeding to curling, the working continuity is high, and the processing efficiency is improved.

Description

technical field [0001] The invention relates to the field of hardware production and manufacturing, in particular to a method and equipment for curling a cotter spring pin. Background technique [0002] The cotter pin is a headless hollow cylindrical body with axial slots and chamfers at both ends. It is used for positioning, connection, fixing, etc. between parts; it needs to have good elasticity and shear resistance. The outer diameter of the class pin is slightly larger than the fitting hole diameter. [0003] Cotter pins are generally formed by crimping, but traditional crimping and forming equipment has the following problems: the work cycle is slow, and in the traditional production process, when the previous cotter pin is processed, the raw materials behind can only wait outside the processing area. One processing is completed, and the latter enters the processing area, resulting in poor continuity when the equipment is working, and can only be processed intermittent...
