Abstract

A kind of split type shearing punch die of the utility model, comprising: inner side drift, outside drift, screw thread, push rod; Described inner side drift and outside drift are threaded connection, and screw thread screws between rear inner side drift and outside drift and forms storage cavity; Described inner side nose of punch also comprises cutting edge inner chamber; Described push rod is used for the part in storage cavity to eject when discharging; The while that the utility model providing and can realize, internally exit orifice is processed, and can realize continuous punching, greatly enhance productivity, and part is convenient to remove, can not impacts the crudy of part.

Description

A kind of split type shearing punch die

Technical field

The utility model relates to a kind of mould, and particularly one split type shearing punching is unconcerned.

Background technology

Stamping-out refers to a kind of stamping procedure utilizing punch die to make portion of material, work (sequence) part to be separated with another part material, work (sequence) part or waste material, and in this operation, blanking die directly will determine the workpiece quality and the working (machining) efficiency that need processing.

For annular element, especially for the punch process of plastic sealing gasket, if adopt the punch die of specialty to carry out automated production, working (machining) efficiency is higher, but initial stage input cost is higher, is generally only suitable for processing in enormous quantities.

When small lot batch manufacture, interior hole machined and Excircle machining two procedures generally can be divided into realize.No matter be that first carrying out punching to foreign round carries out punching to endoporus again, still first carry out punching to endoporus and carry out punching to foreign round again, owing to there is secondary punching, operation relative distribution, working (machining) efficiency is not high.

Carry out punching according to integral type annular shearing die, the problem brought can be stuck in the cavity of mould after part punching, takes out very inconvenient, choose according to sharp instrument, not only there is the hidden danger damaging shearing die cutting edge, and cut can be left on part, affect the quality of part.

Utility model content

For above problem, the utility model provides a kind of split type shearing punch die, can realize simultaneously internally exit orifice and process, and continuous punching can be realized, greatly enhance productivity, and part is convenient to remove, can not impacts the crudy of part.

In order to realize the purpose of this utility model, the utility model provides a kind of split type shearing punch die.

A kind of split type shearing punch die, comprising: inner side drift, outside drift, screw thread, push rod;

Described inner side drift and outside drift are threaded connection, and screw thread screws between rear inner side drift and outside drift and forms storage cavity;

Described inner side nose of punch also comprises cutting edge inner chamber;

Described push rod is used for the part in storage cavity to eject when discharging.

Further technical scheme, described cutting edge inner chamber is sphere chamber.

beneficial effect

Adopt the utility model structure simple, easy to use, have the following advantages:

1, a kind of split type shearing punch die cost of manufacture of the utility model is lower, and use under being especially applicable to the condition of production of small lot, and can realize continuous stamping, working (machining) efficiency is high.

2, the cutting edge inner chamber of a kind of split type shearing punch die of the utility model is sphere inner chamber, and after punching, inner ring shears waste material meeting self falling;

3., after the continuous punching of a kind of split type shearing punch die of the utility model, the part in storage cavity, can use push rod to take out, easy to operate, and can not impact part quality.

Detailed description of the invention

Below in conjunction with Figure of description, the utility model will be further described.

Embodiment

As shown in Figure 1 to Figure 3

A kind of split type shearing punch die, comprising: inner side drift 1, outside drift 2, screw thread 5, push rod 7; Inner side drift 1 is connected by screw thread 5 with outside drift 2, and screw thread 5 screws between rear inner side drift 1 and outside drift 2 and forms storage cavity 3; Inner side nose of punch also comprises cutting edge inner chamber 4, and cutting edge inner chamber 4 is sphere chambeies; Push rod 7 is used for the part 6 in storage cavity 3 to eject when discharging.

Punching adds man-hour:

The first step: inner side drift 1 is connected by screw thread 5 with outside drift 2, screws;

Second step: a kind of split type shearing punch die is arranged on lathe by the step of inner side drift 1 upper end;

3rd step: by material thickness and storage cavity 3 degree of depth, the multiple part 6 of continuous punching;

4th step: screw off outside drift 2, part 6 can be stayed in the drift 2 of outside;

5th step: with push rod 7, the multiple parts 6 in outside drift 2 are ejected together, complete processing.

Schematically above be described the utility model and embodiment thereof, this description does not have restricted, and also just one of the embodiment of the present utility model shown in accompanying drawing, actual structure is not limited thereto.So, if those of ordinary skill in the art enlightens by it, when not departing from the utility model and creating aim, design the frame mode similar to this technical scheme and embodiment without creationary, protection domain of the present utility model all should be belonged to.

Claims (2)

1. a split type shearing punch die, is characterized in that, comprising: inner side drift, outside drift, screw thread, push rod;
