Abstract
The invention discloses a punch of a mold. The punch comprises a first rod body, a second rod body, a punch cap, a sleeve, a spring box, a screw hole and a controller, wherein the first rod body is connected with the second rod body; the sleeve is arranged inside the first rod body; the spring box is arranged inside the second rod body; a spring is mounted in the spring box; the screw hole and the spring controller are further arranged on the second rod body; and the punch cap is arranged at the other end of the second rod body. According to the punch, the impact force of a punch rod is reduced by the aid of the spring, so that abrasions of the punch rod of the mold are reduced, and the service life of the punch rod of the mold is prolonged.
Description
Technical field
The present invention relates to drift field, particularly relate to a kind of mold and punching head.
Background technology
Drift is mounted in the metal parts in diel, is applied to contact with the direct of material, makes material generation shape
Become, cut material.Mold and punching head typically uses high-speed steel and wolfram steel etc. as material, has high-speed steel drift and wolfram steel drift etc.,
And high-speed steel is the most frequently used material, conventional has CR12, CR12MOV, asp23, skd11, skd51, skd61 etc., wolfram steel
Material is commonly used in and requires on higher punching and shearing die.In routine duties, drift can produce abrasion, and main abrasion includes:
Mechanical wear and thermal wear, reduce quality and the precision of mould, need often to change drift, considerably increase the production of mould
Cost.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of mold and punching head, and it is reasonable in design, and simple in construction solves
The problem that drift is in use difficult to change red needle.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is to provide a kind of mold and punching head, comprising:
First body of rod, second body of rod, rush cap, sleeve, spring box, screw and controller；Described first body of rod and second body of rod are connected；Institute
State and be provided with sleeve inside first body of rod；It is provided with spring box inside described second body of rod；Described spring is arranged in spring box；Described
Screw and control spring device it is additionally provided with on second body of rod；The described cap that rushes is arranged on the other end of second body of rod.
Preferably, the diameter of described first body of rod is less than the diameter of second body of rod.
Preferably, the described cap that rushes is provided with keyway.
Preferably, described screw has two and along centrage symmetry.
The invention has the beneficial effects as follows: the present invention makes plunger rod reduce impulsive force by spring, thus reduces mould
The abrasion of plunger rod, adds the service life of mold and punching head bar.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of mold and punching head of the present invention；
Fig. 2 is the front view of a kind of mold and punching head of the present invention；
In accompanying drawing, the labelling of each parts is as follows: 1, first body of rod；2, second body of rod；3, cap is rushed；4, sleeve；5, spring box；6, spiral shell
Hole；7, control spring device.
Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
Referring to accompanying drawing 1 and Fig. 2, the embodiment of the present invention includes: first body of rod 1, second body of rod 2, rush cap 3, sleeve 4, bullet
Spring case 5, screw 6 and controller 7；Described first body of rod 1 is connected with second body of rod 2；Described first body of rod 1 is internal is provided with sleeve 4；
Described second body of rod 2 is internal is provided with spring box 5；Described spring is arranged in spring 5 casees；It is additionally provided with spiral shell on described second body of rod 2
Hole 6 and control spring device 7；The described cap 3 that rushes is arranged on the other end of second body of rod 2.The diameter of described first body of rod 1 is less than second body of rod
The diameter of 2；The described cap 3 that rushes is provided with keyway；Described screw 5 has two and along centrage symmetry.
When deployed, red needle being installed in drift, red needle top is withstood spring handle red needle and is put in drift, then by two
Individual screw 6, is fixedly clamped red needle further with screw and prevents from loosening in drift.Drift is made to reduce impact by spring
Power, thus reduce the abrasion of mold and punching head, add the service life of mold and punching head bar.When changing, as long as loosening screw 6
Interior screw, then presses control spring device 7, and spring will eject red needle in drift, therefore be easily changed drift.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilize this
Equivalent structure or equivalence flow process that bright description is made convert, or are directly or indirectly used in other relevant technology necks
Territory, is the most in like manner included in the scope of patent protection of the present invention.
