Trimming mold for machining movable pole plate connecting piece of electrostatic precipitator

Abstract

The invention relates to a trimming mold for a machining movable pole plate connecting piece of an electrostatic precipitator. The trimming mold is characterized by comprising an upper mold and a lower mold fitting with each other, wherein the upper mold comprises an upper template; a mold handle is arranged at the upper side of the upper template; the lower side of the upper template is respectively connected with a trimming punch and an elastic piece; the lower mold comprises a lower template; a trimming lower mold is mounted on the lower template; a guide rail is additionally mounted on the lower template at one side of an edge of the trimming lower mold, and is provided with a slide block; the slide block is connected with an inclined wedge fitting the trimming punch; a stand plate is arranged in the sliding direction of the slide block; a return piece is arranged between the stand plate and the slide block; and a set of guide devices is arranged between the upper template and the lower template. The trimming mold has the following advantages: the trimming mold is simple and safe in operation, relieves the labor intensity, and improves the workpiece machining efficiency; and the mold is mounted on a punching machine for working, and the stress of the punching machine is uniform, so that the wear coefficient is low.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to an edge trimming die used for processing movable pole plate connecting parts of an electrostatic precipitator. Background technique [0002] Electrostatic dust removal is a kind of gas dust removal method. It means that the dust-containing gas is electrically separated when it passes through a high-voltage electrostatic field. At this stage, electrostatic precipitators are used to achieve electrostatic dust removal. It uses electrostatic fields to ionize gas so that dust particles are charged and adsorbed to electrodes. Electrostatic precipitators use high-voltage DC electric fields to ionize gas molecules in the air, generating a large number of electrons and positive ions. Electrons Dust particles are encountered in the process of running towards the positive electrode, so that the dust particles are negatively charged and adsorbed to the positive electrode to be collected.

Problems solved by technology

[0003] The mobile plate is one of the components of the electrostatic precipitator, and the connecting piece is an important connecting part in the moving plate. The connecting piece is made of angle steel through a series of processes, one of which is trimming. At this stage The edge trimming process is processed on the shearing machine, which is held by the worker's hand during processing to carry out the edge trimming. This processing method is a single-point force on the shearing machine, but due to the large size of the workpiece The cutting edge is relatively close to the inner corner of the angle steel, so this process not only has a high risk factor, but also causes serious damage to the machine tool.
