A hydraulic press for interior parts of high-speed EMU trains

Abstract

The invention belongs to the technical field of processing equipment for interior trim parts of a high speed train and discloses a hydraulic machine for the train interior trim parts of the high speedtrain. The hydraulic machine comprises a lower cross beam and an upper cross beam; the upper cross beam and the lower cross beam are fixedly connected through four symmetrically-arranged stand columns; the upper cross beam is fixedly sleeved with an oil cylinder; two plunger cylinders are symmetrically arranged on the two sides of the oil cylinder; one end of a piston rod of the oil cylinder andone ends of piston rods of the two plunger cylinders are fixedly connected with the upper side of a sliding block; and an electronic pump is arranged on one side of the upper end of the upper cross beam and connected with an oil pump and the plunger cylinders. The hydraulic machine is simple and reasonable in structure, structure materials of the hydraulic machine are saved, equipment weight is reduced, equipment can be carried and transferred conveniently, limiting guidance is carried out on the sliding block through a guide plate, the interval between the guide plate and the sliding block isadjustable, and the guidance precision and unbalance loading resistance of the sliding block are improved.

Description

technical field [0001] The invention belongs to the technical field of processing equipment for interior parts of high-speed EMUs, and in particular relates to a hydraulic press for interior parts of high-speed EMUs. Background technique [0002] The hydraulic press for interior parts of high-speed EMU trains is composed of main hydraulic press, oil heating system, control system, table system, exhaust gas collection system and safety protection system, etc. It can complete the forming process of paper honeycomb panel interior parts and heat treatment of other composite materials. The press forming process can be widely used in the processing of interior parts of high-speed EMU trains, aerospace and other major equipment, and provides important key equipment for the independent research and development of high-speed EMU trains in my country. [0003] However, the hydraulic machine currently used has insufficient frame rigidity and strength, and is too bulky; the slider guide ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a hydraulic press for high-speed EMU train interior parts, to solve the problem of insufficient rigidity and strength of the equipment frame proposed in the background technology, and being too bulky; And the repeated positioning accuracy cannot meet the requirements; in the specific operation, the amount of manual operation is large, and the production efficiency is low.
