Abstract
The utility model relates to a fast-changing punch of a punching die, which comprises a press plug, a convex die sleeve and a convex die; a step through hole is arranged in the male die sleeve, and the male die is of a rotary structure with a boss and is arranged in the step hole of the male die sleeve; the press plug is positioned at the upper part of the step hole of the male die sleeve and tightly presses the male die; the upper end of the male die sleeve is provided with external threads which are used for being in threaded connection with the male die holder, and the female die is arranged in the female die holder and matched with the lower end of the male die; the stripper is sleeved outside the male die sleeve and is positioned between the male die base and the female die. The utility model discloses a structural design of fast drift that trades, fundamentally has solved the drift and has changed, repair, debug the long defect of time, has improved the life of part surface quality and mould, the cost is reduced. The structure design of quickly changing the punch is adopted on the male die fixing structure of the die, so that the defect that the die is required to be disassembled for replacement after the punch of the die is damaged is thoroughly overcome. The punching die can be popularized and applied to punching dies of all vehicle parts.
Description
Technical Field
The utility model belongs to the technical field of vehicle parts machining, concretely relates to punching die fast trades drift.
Background
At present, the punch fixing mode of the punching die for the domestic vehicle parts is that the punch is fixed on a die holder through screws and pins, and the die must be disassembled to replace the punch after the punch is damaged, so that the die is inevitably long in replacing, repairing and debugging time, and the production efficiency is low.
The method of changing the punch material of the die into a high-hardness and wear-resistant material and the like is adopted, so that the production cost is increased, and the production efficiency is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model provides a punching die trades drift fast, and the technical problem who solves is: the technical problem that the time for replacing, repairing and debugging the punching die of the vehicle part is long is solved, and the defect that the die is required to be disassembled for replacement after a punch of the die is damaged is overcome.
In order to solve the technical problem, the utility model provides a quick-change punch of a punching die, which is characterized by comprising a press plug, a convex die sleeve and a convex die; a step through hole is arranged in the male die sleeve, and the male die is of a rotary structure with a boss and is arranged in the step hole of the male die sleeve; the press plug is positioned at the upper part of the step hole of the male die sleeve and tightly presses the male die; the upper end of the male die sleeve is provided with external threads which are used for being in threaded connection with the male die holder, and the female die is arranged in the female die holder and matched with the lower end of the male die; the stripper is sleeved outside the male die sleeve and is positioned between the male die base and the female die.
Has the advantages that: the utility model discloses a structural design of fast drift that trades, fundamentally has solved defects such as "the drift is changed, is repaired, the debugging time is long", has improved the life of part surface quality and mould, the cost is reduced. The structure design of quickly changing the punch is adopted on the male die fixing structure of the die, so that the defect that the die is required to be disassembled for replacement after the punch of the die is damaged is thoroughly overcome. The punching die can be popularized and applied to punching dies of all vehicle parts.

Detailed Description
In order to make the objects, contents and advantages of the present invention clearer, the following description will be made in further detail with respect to the embodiments of the present invention.
The utility model provides a fast-changing punch of a punching die, which comprises a press plug 2, a convex die sleeve 5 and a convex die 6;
a step through hole is arranged in the male die sleeve 5, and the male die 6 is of a rotary body structure with a boss and is arranged at the lower part of the step hole of the male die sleeve 5; the press plug 2 is positioned at the upper part of the step hole of the male die sleeve 5 and tightly presses the male die 6;
the upper end of the male die sleeve 5 is provided with external threads for being in threaded connection with the male die holder 3, and the upper backing plate 1 is fixed on the male die holder 3 and used for pressing the press plug 2 tightly;
the lower part of the male die sleeve 5 is provided with a matching surface which is in clearance fit with the male die holder 3;
the female die 7 is arranged in the female die holder 8 and matched with the lower end of the male die 6 to punch a part 9;
the stripper 4 is sleeved outside the male die sleeve 5 and is positioned between the male die holder 3 and the female die 7;
the bottom end of the male die sleeve is provided with a straight groove, so that the male die sleeve is convenient to disassemble;
the utility model discloses to punch a hole terrace die fixed structure work part designs into and dismantles the drift rapidly on need not dismantling the mould basis, has reduced manufacturing cost and has improved production efficiency, has improved the quality of part simultaneously.
The utility model provides an existing frame class part cut-out press drift fixed knot constructs the mode and adopts the superiority of not changing the drift design rapidly in actual production process with dismantling the mould. From the technical point of view of die design, innovations are made in the aspects of punch replacement elimination, punch repair, long debugging time, productivity improvement, cost reduction and the like.
The advantages are that:
a. the rapid punch structure adopted by the male die of the die is one of the best methods for solving the defect that the punching die is long in punch replacement, repair and debugging time at present.
b. The structure is successfully applied to punching dies of heavy truck frame parts of the company at present.
c. For the punching die, the problem of long punch replacing, repairing and debugging time is solved, and the advantages are as follows: the production cost is reduced, the production efficiency is improved, and the quality of parts is improved.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
