Description

A bottom marking pin structure for deformation processing mold

technical field

The utility model relates to a deformation processing mould, in particular to a bottom mark pin structure with adjustable position in the deformation processing mould.

Background technique

Stamping dies, drawing dies, and forming dies used for deformation processing of materials all need to design bottom marking pins, which are used to check the bottom state of the mold during processing, so as to detect whether the part is drawn or formed final state of . The traditional bottom mark pin installation structure is to process the bottom mark installation hole on the die base of the drawing and forming mold by the numerical control machine tool, then assemble the bottom mark pin into the bottom mark installation hole, and then use the screw to connect the bottom mark pin and the bottom mark pin. The upper die is locked. The problems of this traditional structure are as follows: the inspection of stamping parts requires that the indentation depth of the bottom mark of the part is 0.3mm. The depth dimension of the hole is a fixed value and cannot be changed, so we can only repair the bottom mark installation hole, and then reprocess the bottom mark installation hole. In this way, on the one hand, due to the high processing cost of the CNC machine tool, the production cost of the workpiece is increased;

Utility model content

The purpose of this utility model is to aim at the disadvantages of the prior art, to provide a bottom marking pin structure for deformation processing molds, the structure can adjust the axial position of the bottom marking pin relative to the mold base through the adjustment block, to meet the Requirements for the indentation depth of the workpiece.

Problem described in the utility model is realized with following technical scheme:

A bottom marking pin structure for a deformation processing mold, which includes a mold base and a bottom marking pin, in particular, the structure is also provided with an adjustment block, and the mold base is provided with a mounting hole, the adjustment block and the bottom marking pin. The marking pins are sequentially located in the mounting holes, the adjusting block is screw-fitted with the mounting holes, and the bottom marking pins are fixedly connected with the adjusting block.

In the structure of the bottom mark pin used for the deformation processing mold, the adjustment block is provided with a threaded connection hole, and the bottom mark pin is provided with a screw hole, and the screw passes through the screw hole and is screwed with the threaded connection hole of the adjustment block.

In the bottom marking pin structure used for the deformation processing mold, the upper end of the adjustment block is provided with an inner hexagonal adjustment hole.

In the structure of the above-mentioned bottom marking pin used for the deformation processing mold, the bottom marking pin and the mold base are in clearance fit.

In the structure of the bottom marking pin used for the deformation processing mold, the screw hole of the bottom marking pin is a stepped hole, and the screw is a hexagon socket head cap screw.

The utility model solves the problem that the adjustment of the existing bottom mark pin needs to reprocess the hole, which takes a long time and costs high. Screw connection is adopted between the pin and the adjustment block. The utility model takes the adjusting block as the positioning reference of the bottom marking pin, and can adjust the axial position of the adjusting block relative to the mold base as required, so as to meet the requirement of the pressing depth of the bottom marking pin on the workpiece. By adopting the utility model, the axial position of the bottom marking pin relative to the mold base can be changed conveniently and quickly without repair welding and CNC machine tool processing, and the mold debugging cycle is greatly shortened while reducing the production cost.

Detailed ways

With reference to Fig. 1-3, the utility model comprises mold base 1, mark pin 2, adjustment block 4 at the end. The mold base 1 is provided with mounting holes, and the adjustment block 4 and the bottom marking pin 2 are sequentially assembled in the mounting holes. The adjustment block 4 is composed of two sections of cylinders with different diameters. The diameter of the cylinder at the upper end of the adjustment block is relatively large, and an inner hexagonal adjustment hole 4-2 is provided at the upper end of the adjustment block; For screw fit, the adjustment block is also provided with a threaded connection hole 4-1. The outline of marking pin 2 at the end is cylindrical, and it is positioned at the adjustment block top, and marking pin 2 at the end fits with mold base 1 clearance. The bottom mark pin valve is provided with a stepped screw hole 2-1, and the screw 3 passes through the screw hole 2-1 and screw-fits with the threaded connection hole 4-1 of the adjustment block, so that the bottom mark pin and the adjustment block form a fixed connection.

Referring to Fig. 1, when the utility model is used, the adjustment block 4 is first screwed into the installation hole of the mold base through the external thread provided by itself; on block 4. During the mold adjustment process, if the imprint of the bottom mark pin on the workpiece is shallow, remove the bottom mark pin, rotate the adjustment block, and adjust the axial position of the adjustment block upwards appropriately, so that the indentation of the bottom mark pin meets the The needs of the workpiece; similarly, when the bottom marking pin is deeply imprinted on the workpiece, the adjustment block should be adjusted downwards to meet the production needs of the mold.
