Abstract

A punching die device comprises a bowed punching die body, where a lower die of the bowed punching die body is provided with a lower die sleeve, an upper die of the punching die bow body is provided with an upper die sleeve corresponding to the lower die sleeve, a punch head is sheathed in the upper die sleeve, and a concave die is sheathed in the lower die sleeve. The punching die device can fast adapt to product changes, when product aperture changes or the punch head and the concave die are worn, only the single punch head and the concave die need to be replaced, thus avoiding waste of fund and time for the development of overall punching die, further improving product development speed and meeting requirement on product machining accuracy.

Description

The perforating die device

Technical field

The utility model relates to a kind of perforating die device, is applicable to automobile frame crossbeam, the dull and stereotyped plate punching of smallclothes.

Background technology

When production frame cross smallclothes plate, there is dual mode processing position, plate hole, is respectively boring and punching at present, the borehole accuracy instability, and efficient is low, and operation labour intensity is higher relatively, and hole inwall quality is coarse.Whole punch die is now all adopted in punching, and whole punch die investment is big, and fabrication cycle is long, and inconvenient maintenance more can not adapt to the fast characteristics of existing automobile industry variety variations.

The utility model content

The purpose of this utility model be to overcome the deficiency of prior art and provide a kind of simple in structure, change drift and die perforating die device easily.

The purpose of this utility model is achieved by following technical proposals:

A kind of perforating die device, comprise punch die bow body, on the counterdie of described punch die bow body lower die-sleeve is installed, the position of corresponding described lower die-sleeve is equipped with Upper Die-sleeve on the patrix of described punch die bow body, be set with drift in the described Upper Die-sleeve, be set with die in the described lower die-sleeve.

Owing to adopt said structure, drift and die are set in Upper Die-sleeve and the lower die-sleeve, when product varying aperture or drift, die wearing and tearing, only need single drift of replacing and die to get final product, avoided developing fund, the waste of time of whole punch die, more can improve product development speed and guarantee the required precision that product is processed.

In the accompanying drawing 1,2: 1---punch die bow body, 2---drift, 3---drift packing ring, 4---polyurethane, 5---Upper Die-sleeve, 6---spring, 7---plate, 8---die, 9---lower die-sleeve, 10---punch press top shoe seat, 11---punch press workbench.

The specific embodiment

Below in conjunction with accompanying drawing, describe the specific embodiment of perforating die device in detail.

As shown in Figure 1, a kind of perforating die device, comprise punch die bow body 1, on the counterdie of described punch die bow body 1 lower die-sleeve 9 is installed, the position of corresponding described lower die-sleeve 9 is equipped with Upper Die-sleeve 5 on the patrix of described punch die bow body 1, be set with drift 2 in the described Upper Die-sleeve 5, be set with die 8 in the described lower die-sleeve 9.

Punch die bow body 1 is placed on the punch press workbench 11, patrix is loaded onto Upper Die-sleeve 5 successively, spring 6, polyurethane 4, drift packing ring 3, drift 2, counterdie is loaded onto lower die-sleeve 9 successively, die 8, to treat that punching material 7 is placed on the counterdie and has good positioning, punch press top shoe seat 10 falls then, spring 6 compressions, the lower die-sleeve 5 descending plates 7 of pushing down, drift 2 continues descending, drives drift packing ring 3 compression polyurethane 4, until drift 2 plate 7 is dashed and to wear, punch press top shoe seat 10 backhauls afterwards make progress, and drift 2 is finished the material returned under the resilience of polyurethane 4 drives, and Upper Die-sleeve 5 is return under the resilience of spring 6 drives, the punching material is discharged by the chip-removal hole in the lower die-sleeve 9, and the plate punching is finished.

Claims

1. perforating die device, comprise punch die bow body (1), it is characterized in that: on the counterdie of described punch die bow body (1) lower die-sleeve (9) is installed, the position of corresponding described lower die-sleeve (9) is equipped with Upper Die-sleeve (5) on the patrix of described punch die bow body (1), be set with drift (2) in the described Upper Die-sleeve (5), be set with die (8) in the described lower die-sleeve (9).
