Abstract
The utility model relates to a punching die structure and particularly provides a punch structure fast to replace. The punch structure comprises an upper die base, a lower die base and a pull rod base plate. The upper die base is provided with an upper clamping plate. A sliding groove for the pull rod base plate to slide in is formed between the upper clamping plate and the upper die base. The upper claming plate is sequentially provided with a stripping back plate and a stripper plate. The upper clamping plate, the stripping back plate and the stripper plate are provided with punch holes. Punches are installed in the punch holes. The tail portions of the punches are arranged in the sliding groove and make contact with the lower surface of the pull rod base plate. The lower surface of the pull rod base plate is of a step shape. The transition face between every two steps is the inclined face, the pull rod base plate is pushed, and the tail portions of the punches are ejected out downwards by means of the inclined faces. A lower die plate is installed on the lower die base. A core is installed in the lower die plate. A stripper centre is arranged in the core. According to the punch structure fast to replace, on the premise that a die is not disassembled, the punches are replaced, so that the specifications of punching products are fast to switch.
Description
Technical field
The utility model relates to a kind of punching die structure, is specially quick-replaceable punch structure.
Background technology
For a batch multiple and similar product needed punching, or same parts rush multiple different holes, and as each product is opened a mold, or the method that same cover die changes with drift realizes the different holes of punching press, the time long, cost is high, wastes resource.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of quick-replaceable punch structure, can carry out punching to different product, and can rush different holes, and concrete technical scheme is:
Quick-replaceable punch structure, comprise upper bolster and die shoe, also comprise pull bar backing plate, pull bar backing plate can horizontal slip on the lower surface of upper bolster, upper bolster is provided with train wheel bridge, between train wheel bridge and upper bolster, leaving chute slips into for pull bar backing plate, de-backboard and stripper plate are installed on train wheel bridge successively, train wheel bridge, on de-backboard and stripper plate, there is bore of the punch, drift is arranged in bore of the punch, the afterbody of drift contacts with pull bar backing plate lower surface in chute, pull bar backing plate lower surface is stepped, excessive face between every layer of ladder is inclined-plane, pushing drawing rod backing plate, rely on inclined-plane that drift tail down is ejected,
Lower bolster is arranged on die shoe by lower bolster, and the position of the corresponding drift of lower bolster is provided with into son, enters son and is arranged on lower bolster by briquetting, enters and in son, has de-material thimble.
Described pull bar backing plate lower surface has multi-step.
Pull bar backing plate is provided with handle.
On pull bar backing plate, there is locating hole, on upper bolster, have pilot pin, when pilot pin is inserted into locating hole, position; The part design that the position of locating hole and pilot pin processes as required.
The quick-replaceable punch structure that the utility model provides, in the time need to producing several different product in same mould, use this structure under the prerequisite mould not being removed, more to finish changing drift, to reach the specification object of quick switching stamping products.Save greatly the time, improved operating efficiency and provided cost savings.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model;
Fig. 2 is the structural representation of looking up of pull bar backing plate of the present utility model.
The specific embodiment
The accompanying drawings specific embodiment of the present utility model.
As shown in Figure 1, quick-replaceable punch structure, comprise upper bolster 1 and die shoe 5, also comprise pull bar backing plate 2, pull bar backing plate 2 can horizontal slip on the lower surface of upper bolster 1, pull bar backing plate 2 upper bolsters 1 are provided with train wheel bridge 10, between train wheel bridge 10 and upper bolster 1, leaving chute slips into for pull bar backing plate 2, de-backboard 11 and stripper plate 12 are installed on train wheel bridge 10 successively, train wheel bridge 10, on de-backboard 11 and stripper plate 12, there is bore of the punch, drift 6 is arranged in bore of the punch, the afterbody of drift 6 contacts with pull bar backing plate 2 lower surfaces in chute, pull bar backing plate 2 lower surfaces are stepped, excessive face between every layer of ladder is inclined-plane, pushing drawing rod backing plate 2, rely on inclined-plane that drift 6 tail down are ejected,
Described pull bar backing plate 2 lower surfaces have multi-step.
Pull bar backing plate 2 is provided with handle 3.
As shown in Figure 2, have locating hole 21 on pull bar backing plate 2, have pilot pin 11 on upper bolster 1, pilot pin 11 positions while being inserted into locating hole 21; The part design that the position of locating hole 21 and pilot pin 11 processes as required.
When processing, workpiece 4 to be punched is placed on lower bolster 13, pushing drawing rod backing plate 2, utilizes inclined-plane to drive drift 6 to carry out stamping-out.
In the time need to strengthening the stroke of drift 6, only need to change pull bar backing plate 2.
In the time needing the hole of the multiple diverse locations of punching press simultaneously, design locating hole 21 and the pilot pin 11 of position, different hole, carry out regioselective according to the position in each hole.
