Pressing device for pump chamber copper bush press-fitting

Abstract

The invention discloses a pressing device for pump chamber copper bush press-fitting. The pressing device for the pump chamber copper bush press-fitting comprises a bottom seat, a workbench, supporting columns, a punching table, a lifting plate, a connecting plate, a lifting block, a base, a punching plate, a stamper, a bottom die, air pressure boxes, first positioning telescopic rods, rotating grooves, rotating balls, piston grooves, baffles, telescopic holes, rubber pistons, sliding rails, sliding grooves, pressurizing pipes, a mounting hole, a hydraulic cylinder and a second positioning telescopic rod. The four supporting columns are uniformly fixed to the upper surface of the bottom seat, the workbench is arranged above the bottom seat, and the workbench is fixedly connected with the supporting columns, and the punching table is fixed to the side edge of the upper surface of the workbench. According to the pressing device for the pump chamber copper bush press-fitting, the first positioning telescopic rods and the second positioning telescopic rod are used for compressing the gas in the air pressure boxes to overcome the deflect that the bottom die is destroyed and the servicelife of the bottom die is shortened due to excessive pressure impact on the bottom die. The placement and positioning of a copper bush can be conveniently achieved through the first positioning telescopic rods, the position of the copper bush can be conveniently adjusted through balls at the tops of the first positioning telescopic rods, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of copper sleeve pressing, in particular to a pressing device for pressing and fitting copper sleeves in pump chambers. Background technique [0002] Copper sleeves, also known as copper shaft sleeves, are divided into various types, including machine copper rollers, copper bearings, etc. It is used in various light industry, large and heavy machinery, and is an important component of machinery. The product has the function of traditional tin bronze bearing. It is made of electrolytic copper with various trace metal elements, sintered at high temperature, and processed by air pressure centrifugal casting. High hardness, excellent wear resistance, not prone to seizure, good casting performance and cutting performance, and good corrosion resistance in the atmosphere and fresh water. Under the conditions of lack of lubricant and water quality lubricant, it has good sliding and self-lubricating properties, eas...

Problems solved by technology

[0003] The pressing of the copper sleeve is an important procedure in the processing of the copper sleeve. The ordinary copper sleeve pressing device is not efficient enough for the positioning of the copper sleeve, resulting in low efficiency in the pressing process; the ordinary pressing device does not have a cushioning function. The damage of the mold is high, which reduces the service life of the bottom mold. Therefore, we propose a pressing device for the copper sleeve of the pump chamber
