Pressing device for workpiece with notch and pin pressing device

Abstract

The invention discloses a pressing device for a workpiece with a notch and a pin pressing device, and belongs to the technical field of post-machining of die-casting products. The pressing device for the workpiece with the notch and the pin pressing device are used for fixing the workpiece with a notch structure, the pressing device comprises an installing base, a pressing mechanism for pressing and fixing the end face of the workpiece is arranged on the installing base, an abutting mechanism is further arranged on the installing base, the abutting mechanism is located on the side, away from the pressing mechanism, of the workpiece, and the end part of the abutting mechanism extends into the notch of the workpiece. According to the pressing device for the workpiece with the notch and the pin pressing device for assembling the side wall of a tool, the pressing mechanisms and the abutting mechanism are arranged in a matching mode, the abutting force is applied to the side wall of the notch of the workpiece, it is guaranteed that the abutting mechanism abuts against the side wall of the workpiece all the time, the situation that a gap is generated between the workpiece and the abutting mechanism in the workpiece machining process, and the whole device is caused to be deformed is avoided, the whole device is stable in workpiece clamping, and the rejection rate of workpiece machining is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of post-processing of die-casting products, and in particular relates to a pressing device and a pressing pin device for workpieces with notches. Background technique [0002] At present, in the automotive industry, during the processing of an auto part, one or more floating support mechanisms are usually used to distribute the force on the part to each support mechanism for the position that is easily deformed and bears a large force , to avoid deformation of parts. [0003] However, for some bent parts or parts with notches, when processing the side walls of these parts, the lateral extrusion force will cause the parts to bend and shrink toward the notches, resulting in deformation of the entire product , causing the product to be scrapped. [0004] For bending parts or parts with notches, the existing processing method is often to set some supports on the mounting base, fill the notches and bending part...
