Full-automatic encapsulated piston production equipment

Abstract

The invention discloses full-automatic encapsulated piston production equipment. The equipment comprises a feeding mechanism, a pre-encapsulation mechanism and an encapsulation mechanism which are sequentially arranged on a stander, and is characterized by also comprising a turning conveying mechanism between the pre-encapsulation mechanism and the encapsulation mechanism, and a control module for controlling the four mechanisms, wherein the feeding mechanism comprises a conveying belt I and a feeding clamp for pushing pistons to be encapsulated on the conveying belt I to the pre-encapsulation mechanism; the pre-encapsulation mechanism comprises a turntable for holding a film, a conical die, a film taking manipulator for conveying the film to the conical die, a lower pressing head above the conical die, and a clamping manipulator for lifting the conical die; and the turning conveying mechanism comprises a conveying belt II for conveying the pre-encapsulated pistons automatically pushed by the pre-encapsulation mechanism, a turning manipulator which is positioned at the tail end of the conveying belt II and is used for turning the pre-encapsulated pistons, and a shaping arm which is used for shaping the pre-encapsulated pistons and conveying the shaped pistons to the encapsulation mechanism.

Description

technical field [0001] The invention relates to a production device of a shock absorber piston, in particular to a device for rubberizing the shock absorber piston. 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 put the film on the piston and heat t...

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 Removing the excess film at the lower mouth by machining, as disclosed in a Chinese patent application with the publication number CN101422966A discloses a polytetrafluoroethylene coating process and equipment for automobile shock absorber pistons, including an A-shaped mold, a die and a hollow cylinder. The pre-compression mold and the covering mold composed of a cylindrical cavity lower mold and a hollow upper mold, put the annular diaphragm on the A-shaped mold, put the piston into the concave mold and fix it, and use the A-shaped mold and the hollow cylinder to seal the annular diaphragm. Press into the first slot of the piston to complete the pre-compression, put the piston on the lower mold mouth of the coating mold, after heating in the infrared oven, the upper mold presses the piston into the lower mold, stretches the annular diaphragm, and after cooling Trim the excess burrs outside the coating film

This kind of semi-automatic rubber encapsulation equipment still needs to be operated by human beings, and the problem of low efficiency is not well solved
