Description
Technical field
The utility model relates to a kind of mould, especially relates to a kind of punching die that the deburring of automobile wheel cover separates that is used for.
Background technology
At present; In the Automotive Cold Pressing Dies tool with in position deburring and the punching; Need be designed to same preface during structural design, having the separation punching die of many wheel cover parts eccentric swage and mold integral discontinuity all can occur, to cause the edge of a knife to damage too fast, and the easy undercut of drift makes part situation such as burr occur; Part often need be done over again, and consumes lot of manpower and material resources.
The utility model content
The purpose of the utility model is exactly for the defective that overcomes above-mentioned prior art existence a kind of punching die that the deburring of automobile wheel cover separates that is used for to be provided.
The purpose of the utility model can realize through following technical scheme:
A kind of punching die that is used for automobile wheel cover deburring separation is characterized in that comprising:
Counterdie: comprise that die shoe, counterdie are inserted, balance nitrogen cylinder and counterdie Lifting Device, described die shoe is located at the bottom, and described counterdie is inserted and is installed on the die holder, and described counterdie Lifting Device is located at the middle part of die shoe;
Patrix: comprise upper bolster, patrix side cut crop, patrix drift, patrix eccentric swage and upper ejector pin; Described upper bolster top is provided with described upper ejector pin; The bottom connects the patrix eccentric swage; Described patrix drift is located at the sidepiece of patrix eccentric swage, and described patrix side cut crop is arranged on the bottom of patrix drift.
Described balance nitrogen cylinder is the cushioning balance device of mould.
Be connected through the contact of inner equilibrium piece between described patrix eccentric swage and the die shoe.
Adopt balance nitrogen cylinder and inner equilibrium piece to have solved to receive in the mold work process strong impulsive force make the mold notch position damage with the mold work process in these two problems of rate of decay of the discontinuity quickening edge of a knife and drift.
Compared with prior art, the utlity model has following advantage:
(1) long service life: used balance and the buffering of nitrogen cylinder, reduced the infringement that vibrations and strong impulsive force cause mould as mold integral.Stress balance when having used the inner equilibrium piece to keep in touch between last eccentric swage and the counterdie reduces the rate of decay of mould.
(2) easy to maintenance: as to go up eccentric swage and use the upper push rod structure convenient for maintaining, do not need the preceding inspection of each production or change the binder power source.
(3) safe and reliable: this mould has used upper push rod structure to get rid of the mould that in the past uses spring, and spring life is short to be damaged easily, in case do not change the shortcomings such as risk of damaging or hurting sb.'s feelings with regard to the handlebar die ontology timely.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
A kind of punching die that is used for automobile wheel cover deburring separation; Its structure is as shown in Figure 1, and this is used for punching die that the deburring of automobile wheel cover separates and is made up of counterdie, patrix respectively, and counterdie comprises that die shoe 1, counterdie insert 3, balance nitrogen cylinder and counterdie Lifting Device 5; Patrix comprises upper bolster 7, patrix side cut crop 8, patrix drift 2, patrix eccentric swage 4 and upper ejector pin 6; Die shoe 1 is positioned at below, and counterdie is inserted and 3 is arranged on the die shoe 1, and counterdie Lifting Device 5 is positioned at the centre position of die shoe 1; Upper bolster 7 upper surfaces are connecting upper ejector pin 6; Connecting patrix eccentric swage 4 below, patrix drift 2 is arranged at the next door of patrix eccentric swage 4, and patrix side cut crop 8 is arranged on below the patrix drift 2.Balance nitrogen cylinder is as the buffer unit of mould.Used inner equilibrium piece 9 to be connected between last eccentric swage and the counterdie; Stress balance when keeping in touch, balance nitrogen cylinder and inner equilibrium piece 9 these two devices solved simultaneously receive in the mold work process strong impulsive force make the mold notch position damage with the mold work process in these two problems of rate of decay of the discontinuity quickening edge of a knife and drift.
The motion principle that is used for the punching die of automobile wheel cover deburring separation: when press is depressed with specified pressure, have last eccentric swage that tablet is compressed; Do the deburring action by edge iron then; Do the shaping action by dressing blade at last; A punching press action is covered, and press rises bottom knockout device jack-up part and takes out.
Claims (3)
1. one kind is used for the punching die that the deburring of automobile wheel cover separates, and it is characterized in that comprising:
