Abstract
The invention claims a punching assembly of CH hole (check hole), comprising a punching head provided with a convex stretch part; and a module torsion provided with a first containing hole for containing the convex stretch part of the punching hole, the ends of the punching head and the module torsion are provided with an outside thread, the punching assembly further comprises two thread sleeves, the thread sleeve is provided with a second containing hole, an inside thread is arranged on an inner wall of the containing hole, the punching head and the module torsion can actively extend into the second containing hole of the thread sleeve and can be respectively threaded with the thread sleeves. Two thread sleeves are additionally arranged in the punching assembly so as to meet the needs of punching the CH holes with different diameter, to conveniently exchange the punching assembly and to increase the production efficiency.
Description
Technical field
The present invention relates to a kind of punching assembly, relate in particular to a kind ofly in automobile panel manufacturing field, the punching assembly in a kind of CH hole of employed drawing die belongs to mechanical manufacturing field.
Background technology
The CH hole is meant that grinding mould uses fabrication hole, adopts the CH hole to carry out the product location when grinding mould, can guarantee the uniformity of preface location, drawing die front and back, thereby reach the purpose that guarantees part accuracy.Functional hole on the non-final products in CH hole, after drawing die debugging was stable, the CH hole need be blocked up, and on product, left a trace preventing, influenced the surface quality of automobile panel.
The CH hole generally is used for making the drawing die of automobile panel, the positioning reference of process mould molding surface size deviation before and after checking when it is die debugging.Therefore, the product that comes out in actual production is not final profiled member, and it has certain resilience, distortion or the amplification of R angle, and postorder grinds just needs this CH hole as benchmark, debugs.
Fig. 1 is to shown in Figure 2 for ginseng, and in the prior art, the punching assembly 100 in CH hole comprises drift 10, and this drift 10 has a convex extension part 101, and mould turns round 11, and mould is turned round 11 and is provided with the accepting hole (not shown) that matches with the convex extension part 101 of drift 10.When needs during towards the CH hole, stamp out drawn component 3 earlier, in upper bolster 1, load onto drift 10 then, in die shoe 2, to load onto mould and turn round 11, the drawn component 3 that will stamp out again is reentered into and goes out the CH hole in the drawing die 100.
At present, the punching assembly 100 in CH hole commonly used is D6 or D10, and it is represented respectively and can go out the CH hole that diameter is 6mm and 10mm.But, when changing the CH bore dia if desired, then need artificial punching assembly from upper bolster 1, die shoe 2, to take out drift 10 respectively and turn round 11 with mould with the CH hole.But drift 10 and mould turn round 11 with upper bolster 1 and die shoe 2 in case just be difficult to be removed after fixing, therefore, shortcoming such as the assembly 100 that dashes in CH of the prior art hole exists and uses inconveniently, changes difficulty, and production efficiency is lower.
In view of this, be necessary the punching assembly in existing C H hole is improved, to address the above problem.
Summary of the invention
The object of the present invention is to provide the punching assembly in a kind of CH hole, it can satisfy the punching press demand in the CH hole of different-diameter, is convenient to the replacing of punching assembly, enhances productivity.
For realizing the foregoing invention purpose, the present invention provides a kind of CH the punching assembly in hole, comprising:
Drift, it is provided with a convex extension part; And
Mould is turned round, and it is provided with one first accepting hole, in order to accommodate the convex extension part of said drift; The end that said drift and mould are turned round is provided with external screw thread; Punching assembly also comprises two swivel nuts, and said swivel nut is provided with one second accepting hole, and its inwall is provided with internal thread; Said drift and mould are turned round in movable second accepting hole that extends into swivel nut, and are spirally connected with swivel nut respectively.
As further improvement of the present invention, second accepting hole of said swivel nut comprises blind hole at least.
Compared with prior art, the invention has the beneficial effects as follows: through in punching assembly, increasing by two swivel nuts, can satisfy the punching press demand in the CH hole of different-diameter, be convenient to the replacing of punching assembly, enhance productivity.
