AI Technical Summary

Technical Problem

When the existing resistor hot pressing machine performs hot pressing of the spring, it lacks the preheating time for the spring to be energized, resulting in a long hot pressing time, low processing efficiency, and cumbersome spring replacement, which affects production efficiency.

Method used

A resistive hot press including a processing table and a transfer mechanism is designed. The transfer mechanism can preheat the spring before hot pressing and automatically rotate the spring back to the workplace after the hot press is completed, which is convenient for replacement. At the same time, the hydraulic cylinder can continue to work to push the pressure plate to heat-press the preheated spring.

Benefits of technology

The preheating function shortens the hot pressing time, improves processing efficiency, and reduces the cumbersomeness of manual operation through the automated replacement process, further improving production efficiency.

Abstract

The invention discloses a resistance hot press for an electric tail door system spring, and relates to the technical field of spring production, the resistance hot press comprises a processing table and a material transferring mechanism, the bottom of the processing table is connected with a plurality of supporting legs, the processing table is connected with two symmetrically distributed fixing plates, the tops of the two fixing plates are jointly connected with a top plate, and the top plate is connected with the material transferring mechanism. A hydraulic cylinder is installed on the top plate, the movable end of the hydraulic cylinder penetrates through the top plate and is connected with a pressing plate, and the material transferring mechanism is installed on the machining table and used for rapidly changing materials of the to-be-pressurized spring. The metal spring hot-pressing device is provided with the material transferring mechanism, so that the metal spring can be preheated before hot pressing, the hot-pressing time is shortened, and the machining efficiency is improved; and after hot pressing is completed, the metal spring continues to rotate along with the material rotating plate to return to the tool position, workers replace the metal spring, in the replacement period, the hydraulic cylinder can continue to work to push the pressing plate to conduct hot pressing machining on the preheated metal spring, and the machining efficiency is further improved.
