Abstract

The utility model provides a precisely -stamping die, the technical problem that solve spacingly do not lead to the problem that the machining precision is low well at stamping die work time. A precisely -stamping die, includes upper die base and die holder, even has last module on the upper die base, goes up the module and links to each other with the terrace die, even has lower module on the die holder, is equipped with the die in the lower module, and it has a spacing section of thick bamboo still to link on the upper die base, is equipped with spacing post in the spacing section of thick bamboo, and spacing post lower extreme is fixed on the die holder, and spacing post upper end links to each other with spacing bolt after passing the through -hole on the upper die base. The beneficial effects of the utility model are that: the utility model discloses a spacing post on upper die base, the die holder and a spacing section of thick bamboo have played limiting displacement, and as requested orbit when can make the module move down prevents the removal, has guaranteed the machining precision of punching press.

Description

A kind of precise punching die
Technical field
The utility model relates to the decompressor that a kind of machining is used, and is specifically related to the diel that a kind of shock machine is used.
Background technology
Punching press is that depended on pressure machine and mould apply external force to sheet material, band, tubing and section bar etc., makes it to produce plastic deformation or separation, thus obtains the forming and machining method of the workpiece of required form and size.Punch process is the power by means of special pressing equipment, makes plate in mould, directly be subject to deformation force and be out of shape, thus obtains definite shape.
Plate, mould and equipment are the three elements of punch process, and the mould that punching press uses is called diel, are called for short punch die.Punch die is most important in punching press, does not have satisfactory punch die, and batch punching production is just difficult to carry out.Punch die is generally divided into upper die and lower die, and existing punch die is in punching course, and the spacing property between upper die and lower die is bad, once be moved, can reduce machining accuracy.
Utility model content
The utility model provides a kind of precise punching die, the spacing bad problem causing machining accuracy low time the technical problem that solve is diel work.
Content of the present utility model comprises: a kind of precise punching die, comprise upper bolster and die shoe, upper bolster is connected with upper module, upper module is connected with punch, and die shoe is connected with lower module, and lower module is provided with die, upper bolster is also connected with position-limiting drum, be provided with limited post in position-limiting drum, limited post lower end is fixed on die shoe, and limited post upper end is connected with caging bolt through after the through hole on upper bolster.
Described position-limiting drum is four, is distributed in the corner place of upper bolster.
The form that position-limiting drum is threaded connection is connected with upper bolster.
Be provided with chuck bottom described position-limiting drum, limited post upper diameter is large, lower diameter is little, and limited post reducing place defines the projection coordinated with chuck.
The beneficial effects of the utility model are:
The utility model serves position-limiting action by the limited post on upper bolster, die shoe and position-limiting drum, track as requested when upper module can be made to move down, and prevents mobile, ensure that the machining accuracy of punching press.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
In the drawings, 1. upper module, 2. upper bolster, 3. punch, 4. die, 5. lower module, 6. die shoe, 7. limited post, 8. position-limiting drum, 9. caging bolt, 10. chuck, 11. is protruding.
Detailed description of the invention
As shown in drawings, a kind of precise punching die, comprise upper bolster 2 and die shoe 6, upper bolster 2 is connected with upper module 1, upper module 1 is connected with punch 3, die shoe 6 is connected with lower module 5, lower module 5 is provided with die 4, and upper bolster 2 is also connected with position-limiting drum 8, is provided with limited post 7 in position-limiting drum 8, limited post 7 lower end is fixed on die shoe 6, and limited post 7 upper end is connected with caging bolt 9 through after the through hole on upper bolster 2.
In prior art, in order to make upper die and lower die spacing, be generally arrange position-limit mechanism in upper and lower module, after such punch die length service time, still there is the problem of spacing property difference in upper module and lower module wearing and tearing.Position-limiting drum 8, limited post 7 are arranged on upper bolster 2 and die shoe 6 by the utility model, and upper bolster 2 and die shoe 6 are in use not easy to wear.Time decompressor drives upper bolster 2 to move down, under the guide effect of limited post 7, position-limiting drum 8 can only move down along limited post 7.Thus serve good position-limiting action, improve the precision of workpiece.
Wherein, described position-limiting drum 8 is four, is distributed in the corner place of upper bolster 2.
Preferably, the form that position-limiting drum 8 is threaded connection is connected with upper bolster 2.Such setting is convenient to change or adjustment position-limiting drum 8.
Further, be provided with chuck 10 bottom described position-limiting drum 8, limited post 7 upper diameter is large, lower diameter is little, and limited post 7 reducing place defines the projection 11 coordinated with chuck 10.Due to chuck 10 and protruding 11 existence, play position-limiting action, prevent upper bolster 2 displacement that moves up too large.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
