Problems solved by technology
The existing pneumatic actuator spring reaming and flanging machine needs to reverse the direction of the pneumatic actuator spring and reinstall it in the mold after reaming and flanging one end of the copper pipe, and then perform reaming and flanging on the other end of the copper pipe. Side operation, that is, the reaming and flanging at both ends of the copper tube of the pneumatic actuator spring needs to be processed in two processes, and the processing efficiency is low

The invention provides a die assembly mechanism of a chambering and flanging machine for a pneumatic actuator spring. By the adoption of the die assembly mechanism of the chambering and flanging machine for the pneumatic actuator spring, chamfering and flanging can be conducted on the two ends of a copper pipe of the pneumatic actuator spring synchronously, and the machining efficiency is improved. The die assembly mechanism comprises pushing units and a driving device. The die assembly mechanism is characterized in that each pushing unit comprises a driving rod, a rotary shaft, a push block, a gear, a rack and a supporting plate; a cavity is formed in each push block, a guide through groove is formed in the top wall and / or the bottom wall of each cavity, and the racks are fixed to the side walls of the cavities; the extension direction of the racks is the same as the extension direction of the guide through grooves; one end of each rotary shaft is supported on the corresponding supporting plate, and the other end of each rotary shaft stretches into the corresponding cavity from the corresponding guide through groove; the gears are fixedly connected to the portions, located in the cavities, of the rotary shafts, and the gears are in engaged connection with the racks; one end of each driving rod is fixedly connected with the corresponding rotary shaft; the number of the pushing unit is two, and the racks of the two pushing units are oppositely arranged on the two radial sides of the gears; the driving device drives the two pushing units to synchronously push movable die plates on two sides to achieve die assembly.
Description
technical field [0001] The invention relates to processing equipment for pneumatic actuator springs, in particular to a mold clamping mechanism for a hole reaming and flanging machine for pneumatic actuator springs. Background technique [0002] The pneumatic actuator spring includes a spring body, a spring sleeve and a hollow connecting rod. The connecting rod runs through the spring sleeve fixed at both ends of the spring body, and the connecting rod guides the expansion and contraction of the spring; the end of the connecting rod is provided with a reaming and flanging structure to prevent the spring sleeve from moving outward in the axial direction of the connecting rod. The existing pneumatic actuator spring reaming and flanging machine needs to reverse the direction of the pneumatic actuator spring and reinstall it in the mold after reaming and flanging one end of the copper pipe, and then perform reaming and flanging on the other end of the copper pipe. Side operatio...
