Steel plate tailoring blanking die and wedge guide device

Abstract

The invention provides a steel plate tailoring blanking die and a wedge guide device. The steel plate tailoring blanking die comprises an upper die plate and a lower die plate. The lower die plate isprovided with a plurality of discharging openings. The lower die plate is provided with a blanking opening communicating with the discharging openings. The upper die plate is provided with a truing cutter used for tailoring. The lower die plate is provided with a conveying device, a supporting device, a first guide device, a second guide device and a third guide device. The conveying device is arranged at an outlet of the lower die plate. The third guide device comprises a sliding block, a sliding base, a drive block, a guide wheel mechanism, a resetting mechanism and a protecting mechanism. The sliding block is in sliding fitting with the sliding base. The drive block is movably arranged in the sliding block in a penetrating manner. According to the steel plate tailoring blanking die, thesteel plate tailoring efficiency is high, and few defective products of steel plate tailoring are generated. According to the wedge guide device, the guide device is simple in overall structure and good in safety, and improves production precision and production efficiency.

Description

technical field [0001] The invention relates to the field of a blanking die and auxiliary equipment for the blanking die, in particular to a steel plate cutting blanking die and a wedge guide device. technical background [0002] With the advancement of society and the continuous development of science and technology, the requirements for sheet metal processing technology are also constantly increasing. Sheet metal processing uses molds to complete different productions. Among them, blanking molds are more commonly used. In order to To improve the precision of punching, a guide mechanism needs to be installed in the blanking die. When the steel plate passes through the punching die, it will not deviate, resulting in poor punching effect, or causing damage to the punching die, so that the steel can have a good positioning when punching. , to improve the precision of production, but most of the guiding mechanisms in the existing blanking dies are fixed, and most of them use re...

[0002] With the advancement of society and the continuous development of science and technology, the requirements for sheet metal processing technology are also constantly increasing. Sheet metal processing uses molds to complete different productions. Among them, blanking molds are more commonly used. In order to To improve the precision of punching, a guide mechanism needs to be installed in the blanking die. When the steel plate passes through the punching die, it will not deviate, resulting in poor punching effect, or causing damage to the punching die, so that the steel can have a good positioning when punching. , to improve the precision of production, but most of the guiding mechanisms in the existing blanking dies are fixed, and most of them use relatively simple rollers for guidance. This simple roller has relatively large limitations in use and is not easy to Replacement, on the formwork, install guide rollers on both sides of the steel plate to guide the steel plate, and the problem with this method is that if the blanking opening of the mold is relatively large, at the large blanking opening If you do not add guide rollers to guide the steel plate, it will greatly affect the punching accuracy at this position. If the guide rollers are installed at the edge of the blanking port, and the fixed rollers cannot avoid punching by themselves, it will Collision with the cutting tool damages the mold, and its use safety is low
