Description
Technical field
The utility model is related to die apparatus technical field, more particularly to one kind having protective case, length-adjustable thin punch
Structure.
Background technology
At present in machinery manufacturing industry, especially mold manufacturing especially rushes the punch of aperture in some diels
It is very thin, it needs to be strengthened and support, protection sleeve pipe is added usually using overstriking punch back segment or on punch, to be protected
Shield, once and punch abrasion or fracture, whole Zhi Chongtou will scrap, and punch utilization rate is relatively low, higher operating costs, tool
There is certain limitation.
Utility model content
The main purpose of the utility model is to provide one kind protective case, length-adjustable thin punch structure, Ke Yiyou
Effect solves the problems in background technology.
To achieve the above object, the technical solution that the utility model is taken is：
One kind having protective case, length-adjustable thin punch structure, including upper die holder, backing plate and clamping plate, the backing plate setting
Between upper die holder and clamping plate, the middle part of the upper die holder, backing plate and clamping plate offers mounting hole, is located in the upper die holder
Through there is set screw at mounting hole, it is provided with cushion block below the set screw, punch is provided with below the cushion block,
The cushion block and punch are embedded in the inside of mounting hole, and adjustment gasket ring, the bottom of the punch are socketed in the middle part of the punch
End cap is connected to protective case.
Further, the set screw is mutually revolved with the screw thread opened up positioned at the mounting hole top in the upper die holder
It connects.
Further, the upper die holder, backing plate and clamping plate are overlapped mutually, and upper die holder, backing plate and clamping plate corresponding section are opened
If mounting hole concentricity it is identical.
Further, the installation bore dia opened up on the upper die holder and backing plate is equal, the installation opened up on the clamping plate
The diameter in hole is less than the diameter of the mounting hole opened up on the upper die holder and backing plate.
Further, the material of the protective case is polystyrene, and the protective case is step-like component.
Further, the bottom end of the punch and the trepanning in the middle part of protective case are interference fitted.
Further, the punch stretches out in the bottom end 2-8cm of protective case.
Compared with prior art, the utility model has the advantages that：This kind of utility model reasonable design, user
Just, by being provided with protective case, punch can be effectively prevent to fracture, improves its service life, and the protective case has resistance to height
Mild corrosion resistance can effectively prevent wearing and damage, and pass through the cooperation of set screw and adjustment gasket ring, Ke Yiyou
Set screw only need to be backed out dismounting by the adjusting of effect adjustment punch length if punch generates abrasion, and it is corresponding to grind off adjustment gasket ring
Height, can effectively improve the utilization rate of punch, reduce use cost, practical function is suitble to be widely popularized.
Description of the drawings
Fig. 1 is the utility model overall structure diagram.
In figure：1, set screw；2, cushion block；3, punch；4, gasket ring is adjusted；5, protective case；6, upper die holder；7, backing plate；8、

Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
As shown in Figure 1, one kind having protective case, length-adjustable thin punch structure, including upper die holder 6, backing plate 7 and clamping plate 8,
The backing plate 7 is set between upper die holder 6 and clamping plate 8, and the middle part of the upper die holder 6, backing plate 7 and clamping plate 8 offers installation
Hole 9 is located in the upper die holder 6 at mounting hole 9 through having set screw 1, the lower section of the set screw 1 to be provided with cushion block 2,
The lower section of the cushion block 2 is provided with punch 3, and the cushion block 2 and punch 3 are embedded in the inside of mounting hole 9, the punch 3
Middle part is socketed with adjustment gasket ring 4, and the bottom end of the punch 3 is socketed with protective case 5, can effectively realize thus the protection of punch 3 and
Height is adjusted.
Wherein, the set screw 1 is mutually screwed on the screw thread opened up positioned at 9 top of the mounting hole in the upper die holder 6,
Repair easy to disassemble.
Wherein, the upper die holder 6, backing plate 7 and clamping plate 8 are overlapped mutually, and 8 corresponding section of upper die holder 6, backing plate 7 and clamping plate
9 concentricity of mounting hole opened up is identical.
Wherein, 9 diameter of mounting hole opened up on the upper die holder 6 and backing plate 7 is equal, the installation opened up on the clamping plate 8
The diameter in hole 9 is less than the diameter of the mounting hole 9 opened up on the upper die holder 6 and backing plate 7, is limited to protective case 5, anti-on-slip
It is de-.
Wherein, the material of the protective case 5 is mould steel, and the protective case 5 is step-like component.
Wherein, the bottom end of the punch 3 and the trepanning at 5 middle part of protective case are interference fitted.
Wherein, the punch 3 stretches out in the bottom end 2-8cm of protective case 5, achievees the purpose that height is adjusted, improves punch 3
