Angle cutting mould for unfolded material of carriage trough girder

Abstract

The invention discloses an angle cutting mould for unfolded material of a carriage trough girder, which comprises an upper mould seat, a lower mould seat and a punch pin provided with a double-edge port, wherein a locating block capable of extending and contracting up and down is arranged at the position of the center line of the lower mould seat close to a blanking port; the lower mould seat is provided with a groove corresponding to the locating block; a spring is arranged at the bottom of the groove; the locating block is embedded in the groove of the lower mould seat; and the upper end of the spring is connected with the locating block. A guiding column is arranged on the lower mould seat; correspondingly, a guiding sleeve is arranged on the upper mould seat; when the upper mould seat is fallen down, the guiding column is just sheathed inside the guiding sleeve. The application of the mould reduces one or more procedures for turning and locating the part compared with the application of common mould; the production efficiency is greatly increased; the processing precision is increased, and the labor strength of the workers is reduced.

Description

technical field [0001] The invention belongs to a blanking die, and in particular relates to a new type of die used for punching the chamfering and bevel compound cutting of one end and two bending edges of a special automobile compartment channel beam unfolded material. Background technique [0002] For the processing of chamfering and compound chamfering of one end and two bending edges of the channel beam of the special automobile compartment, generally a general-purpose chamfering die, a square punch, and a square punching die hole of the lower die base are used for unloading, or The polygonal single blanking die is used for operations, and the steel plate material needs to be flipped and positioned multiple times. The operation efficiency is low, the labor intensity is high, and there are still relatively large unsafe factors. If multiple positioning is performed, the processing accuracy is poor, which affects product quality. . Contents of the invention [0003] In ...
