Description

technical field [0001] The invention relates to the technical field of production equipment for shock absorber pistons, and more precisely relates to a production line for rubber covering of pistons. Background technique [0002] In the suspension system, the elastic elements vibrate due to the impact. In order to improve the smoothness and comfort of the car, a shock absorber is installed in parallel with the elastic elements in the suspension. When there is relative motion between the frame and axle due to vibrations, the piston in the shock absorber moves up and down. Due to the frequent relative movement between the piston and the shock absorber cylinder, it is necessary to coat the surface of the piston with a wear-resistant and low-friction material, such as polytetrafluoroethylene, to prolong the service life. [0003] The existing methods of piston rubber wrapping mainly include: manually place the rubber covering on the piston, use a manual pressing mechanism to pu...

AI Technical Summary

Problems solved by technology

[0003] The existing methods of piston rubber wrapping mainly include: manually place the rubber covering on the piston, use a manual pressing mechanism to put the film on the piston and heat the female mold, so as to achieve the effect of rubber wrapping. However, this method is artificial The factor is too large and the efficiency is low; another method is to pre-coat the film on the piston first, and use the upper mouth as a reference, then pass the piston from top to bottom through the heating female mold and the shaping female mold, and then put the rubberized piston Remove the excess film at the lower port by machining, such as the Chinese patent application CN201310156296.1, which discloses a fully automatic piston rubber production equipment, including a feeding mechanism, a pre-gluing mechanism and a packaging mechanism that are sequentially arranged on the frame. The glue mechanism also includes an overturning conveying mechanism arranged between the pre-coating mechanism and the glue-covering mechanism, and a control module for controlling the above-mentioned four mechanisms; the feeding mechanism includes a conveyor belt I, and the conveyor belt I The piston is pushed to the feed clip of the pre-encapsulation mechanism; the pre-encapsulation mechanism includes a turntable for placing the film, a cone mold, and the film is sent to the taking-up manipulator on the cone mold, and the The lower pressing head, and the clamping manipulator used to lift the cone mold; the overturning conveying mechanism includes a conveyor belt II that conveys the pre-encapsulated pistons that are automatically pushed from the pre-encapsulation mechanism, and the conveyor belt II at the end of the conveyor belt II will The overturning manipulator that turns the pre-coated piston over, and the shaping arm that can shape the pre-coated piston and transport the shaped piston to the rubber mechanism

The transfer of films, piston rings, and finished and semi-finished products usually uses cylinders to push the objects, resulting in low production efficiency, high energy consumption, and prone to errors leading to low yields. At the same time, the pre-encapsulation process is inefficient and poor in applicability The forming process also needs to be transferred to an external forming device, which further reduces the problem of production efficiency
