Abstract
The utility model provides a printed board punching die which comprises an upper die and a lower die. The upper die comprises an upper die seat, a protruding die fixing plate and a protruding die, wherein the protruding die fixing plate is connected with the lower surface of the upper die seat, and the protruding die perpendicularly stretching out downwards is arranged on the protruding die fixing plate. The upper die further comprises a rectangle spring and a guide sleeve, the rectangle spring is fixed in the upper die seat and stretches out downwards, and the guide sleeve is perpendicularly fixed on the lower surface of the upper die seat. The lower die comprises a lower die seat, a concave die and a guide column, wherein the concave die is arranged under the lower die seat and corresponds to the protruding die in position, the lower die seat further is perpendicularly fixed with the guide column matched with the guide sleeve, and the upper die is opposite to the lower die. According to the printed board punching die, the rectangle spring is arranged in the upper die and can exert larger material pressing force in the punching process, so that hole wall lamination of a printed circuit board (PCB) can be avoided, punching quality is improved, and PCB product quality and process stability are improved. The printed board punching die is simple in structure, convenient to operate, and capable of reducing production cost of enterprises, and improves work efficiency and the resource utilization rate.
Description
Technical field
The utility model relates to the Stamping Die Technology field, particularly a kind of printed board punching die.
Background technology
Punch forming process (Punch Forming Process) is to apply external force by forcing press to being fixed on sheet material in the mould, tubing etc., makes it produce plastic deformation or separation, thereby makes the method for processing forming of the workpiece of required form, size and performance.Punch forming process has the advantages that speed is fast, batch is big, therefore needs equipment (comprising mould) to possess higher automaticity and continuable machining accuracy.
Diel (Punch Mould) is to be used for stamping forming mould, and in batch process at a high speed, the design of diel can have a direct impact with quality and the production efficiency made stamping parts.Diel has stronger specificity, for baroque part, often needs number cover single die; Under the part situation, adopt compound die when reducing station, to realize the automated production of a plurality of operations, thereby raise the efficiency, reduce cost.
Making printed board (Printed Circuit Board, abbreviation PCB) in the correlation technique, because its material is multiple Copper Foil epoxy plate, therefore when PCB is carried out punching, the hole wall lamination can occur, this not only has influence on the quality of PCB product, and can improve percent defective, therefore increase the production cost of enterprise, reduced production efficiency.
The utility model content
Cause above-mentioned defective and the problem that the PCB product quality descends, percent defective rises thereby be prone to the hole wall layering at existing printed board punching die when the punching, the purpose of this utility model provides a kind of printed board punching die that improves punching quality.
In order to achieve the above object, the utility model provides following technical scheme: a kind of printed board punching die, it is characterized in that, and comprising:
Patrix, it comprises upper bolster, punch retainer, punch, and described punch retainer is positioned at the upper bolster below, and it is connected with the lower surface of upper bolster, wherein is provided with the punch that stretches out vertically downward; Also be provided with rectangle spring, guide pin bushing in the described patrix, the top of described rectangle spring is fixed on upper bolster inside, and stretch out downwards its bottom, and described guide pin bushing vertical fixing is in the lower surface of upper bolster;
Counterdie, it comprises die shoe, die, guide pillar, and described die is positioned at the die shoe top, and its position is corresponding with punch, and the upper surface of described die shoe also vertical fixing has the guide pillar that is complementary with guide pin bushing;
Described upper die and lower die are installed relatively.
Preferred as technique scheme, described punch is dismountable spring steel wire, itself and punch retainer combination installation.
Preferred as technique scheme, described patrix also comprises the guide plate that has hole, and it is positioned at the punch retainer below, and the hole that described punch can pass guide plate continues to stretch out vertically downward.
Preferred as technique scheme, the quantity of described rectangle spring is six.
Preferred as technique scheme, the quantity of described guide pillar is two, it is fixed on the upper surface both sides of die shoe symmetrically.
Preferred as technique scheme, described patrix also comprises die shank, and it is positioned at the centre position of upper bolster upper surface, and the upper surface that passes upper bolster stretches out vertically upward.
The printed board punching die that the utility model provides is made up of upper die and lower die, it has set up the rectangle spring in patrix, when carrying out punching technology, can apply bigger pressure-plate-force, therefore can prevent that the hole wall layering from appearring in PCB, improve punching quality, thereby improve PCB product quality and technology stability.This mould structure is simple, easy to operate, can reduce the production cost of enterprise, increases work efficiency and resource utilization.
