Description
Technical field
The utility model relates to machined field, particularly relates to a kind of mold and punching head operator guards.
Background technology
Drift is also punch, patrix, formpiston, red needle etc., and drift is divided into A type drift, T-shaped drift, special-shaped plunger chip.Drift is mounted in the metal parts in diel, is applied to and contacts with the direct of material, makes material generation deformation, cuts material.
In the processing of stamping parts, for the punching of some Small Holes, because aperture is very little, drift is also very tiny, and drift mostly adopts wolfram steel to make, and the fragility of wolfram steel is very large, and during punching, drift is easy to explosion.As occurred, drift bursts, and causes dismounting inconvenient, affects repair procedures and time, affect production line simultaneously and normally produce.
Summary of the invention
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is: how to provide a kind of structure simple, can prevent drift from bursting, the mold and punching head operator guards of convenient disassembly.
In order to solve the problems of the technologies described above, the utility model have employed following technical scheme:
A kind of mold and punching head operator guards, comprises upper bolster, backing plate, patrix and drift, and described drift is vertically successively through described backing plate and patrix, and the upper end of described drift is fixed on described upper bolster; It is characterized in that, described drift is set with a cylindric protective sleeve, the aperture of described protective sleeve and the diameter of described drift match; The upper end of described protective sleeve is fixed on described upper bolster; The top of described patrix is provided with an accommodating hole for accommodating described protective sleeve, and described accommodating hole and described protective sleeve are matched in clearance; Distance between the lower surface of described protective sleeve and the bottom surface of described accommodating hole and the thickness of part to be processed match.
Under the protection of protective sleeve, in the whole punch process of drift, drift only has outside the length matched with the thickness of part to be processed is exposed to all the time; During mold work, after forming parts, patrix is by stop motion, and along with upper bolster continues to move downward, drift starts punching; Protective sleeve moves downward with upper bolster, and like this, the distance between protective sleeve and accommodating hole reduces gradually, and drift is exposed to outer length and also reduces gradually, and under the effect of drift protective sleeve, drift is not easy explosion.In addition, once drift explosion, only protective sleeve need be changed together with drift, can ensure that mould normally works.Like this, make the maintenance of mould convenient, improve operating efficiency.
As optimization, end, described drift upper end has the round boss of radially projection, and the position of the corresponding described boss in upper end of described protective sleeve is provided with a shrinkage pool; The diameter of described shrinkage pool is greater than the diameter of described boss, and the degree of depth of described shrinkage pool is less than described boss thickness; The upper surface of described protective sleeve is provided with several screwed holes vertically arranged, and described protective sleeve is fixed on described upper bolster by the screw from top to bottom through upper bolster.
Because drift upper end is provided with boss, and the upper end of protective sleeve is provided with the shrinkage pool corresponding with boss, and when protective sleeve is fixed on upper bolster, boss is firmly fixed on upper bolster by shrinkage pool.Like this, without the need to being fixed separately drift.Once drift damages, the hold-down screw only need removing protective sleeve just can by protective sleeve and the whole replacing of drift.Improve the maintenance speed of mould, enhance productivity further.
As optimization, described screw is soket head cap screw, and the nut of the corresponding described screw of upper surface of described upper bolster is provided with counterbore, and the degree of depth of this counterbore is greater than the nut thickness of described screw.
Like this, when protective sleeve is fixed on upper bolster, the upper surface of upper bolster, without protrusion, is conducive to the installation of upper bolster.
In sum, it is simple that the utility model has structure, can prevent drift from damaging, raising drift service life; Easy dismounting, easy to maintenance, be conducive to advantages such as enhancing productivity.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment.
Fig. 2 is the structural representation of part A in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
During concrete enforcement, as depicted in figs. 1 and 2, a kind of mold and punching head operator guards, comprise upper bolster 2, backing plate 3, patrix 5 and drift 1, described drift 1 is vertically successively through described backing plate 3 and patrix 5, and the upper end of described drift 1 is fixed on described upper bolster 2; Wherein, described drift 1 is set with a cylindric protective sleeve 4, the aperture of described protective sleeve 4 and the diameter of described drift 1 match; The upper end of described protective sleeve 4 is fixed on described upper bolster 2; The top of described patrix 5 is provided with an accommodating hole 51 for accommodating described protective sleeve 4, and described accommodating hole 51 is matched in clearance with described protective sleeve 4; Distance between the lower surface of described protective sleeve 4 and the bottom surface of described accommodating hole 51 and the thickness of part to be processed match.
Under the protection of protective sleeve, in the whole punch process of drift, drift only has outside the length matched with the thickness of part to be processed is exposed to all the time; During mold work, after forming parts, patrix is by stop motion, and along with upper bolster continues to move downward, drift starts punching; Protective sleeve moves downward with upper bolster, and like this, the distance between protective sleeve and accommodating hole reduces gradually, and drift is exposed to outer length and also reduces gradually, and under the effect of drift protective sleeve, drift is not easy explosion.In addition, once drift explosion, only protective sleeve need be changed together with drift, can ensure that mould normally works.Like this, make the maintenance of mould convenient, improve operating efficiency.
Wherein, end, described drift 1 upper end has the round boss 11 of radially projection, and the position of the corresponding described boss 11 in upper end of described protective sleeve 4 is provided with a shrinkage pool 41; The diameter of described shrinkage pool 41 is greater than the diameter of described boss 11, and the degree of depth of described shrinkage pool 41 is less than described boss 11 thickness; The upper surface of described protective sleeve 4 is provided with several screwed holes vertically arranged, and described protective sleeve 4 is fixed on described upper bolster 2 by the screw 6 from top to bottom through upper bolster 2.
Because drift upper end is provided with boss, and the upper end of protective sleeve is provided with the shrinkage pool corresponding with boss, and when protective sleeve is fixed on upper bolster, boss is firmly fixed on upper bolster by shrinkage pool.Like this, without the need to being fixed separately drift.Once drift damages, the hold-down screw only need removing protective sleeve just can by protective sleeve and the whole replacing of drift.Improve the maintenance speed of mould, enhance productivity further.
Wherein, described screw 6 is soket head cap screw, and the nut of the corresponding described screw 6 of upper surface of described upper bolster 2 is provided with counterbore, and the degree of depth of this counterbore is greater than the nut thickness of described screw 6.
Like this, when protective sleeve is fixed on upper bolster, the upper surface of upper bolster, without protrusion, is conducive to the installation of upper bolster.
