Abstract
The invention discloses a part punching die and relates to the stamping die manufacturing technical field. The part punching comprises an upper die frame and a lower die frame which are connected through a guide sleeve in a sleeving mode; the lower end surface of the upper die frame is provided with two wedge blocks, wherein the wedge-shaped surfaces of the two wedge blocks are opposite to each other; an upper punching needle is arranged between the two wedge blocks; two sliding blocks are arranged on the lower die frame through a sliding groove block respectively; the outer side of each sliding block is provided with a wedge-shaped sliding groove which is in wedge connection with the wedge-shaped surface of the corresponding wedge block; the inner side of each sliding block is provided with a lateral punching needle, wherein the two lateral punching needles are corresponding to each other; the lower die frame is provided with a discharging positioning block which is arranged below the upper punching needle. Compared with the prior art, the problems that the punching processes of the existing automobile part are more and the position error of a hole is produced can be solved.
Description
Technical field
The present invention relates to diel manufacturing technology field, especially a kind of mould for automobile metal plate work punching.
Background technology
Have a kind of auto parts as shown in Figure 1, these auto parts by production method are: first by shaping mould, steel plate punched is shaping, then by two operations, complete and are positioned at the hole a of two sides to auto parts and are positioned at the punching of a hole b of bottom surface.There are the following problems in process of production for this processing method: 1, each operation needs a set of punch die, and not only Making mold becomes and processing cost is high, and inefficiency; 2, because hole a and hole b completes respectively by two operations, the error of twice positioning and clamping generation can cause the position of the holes of punching auto parts to there is error.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of part punching die, and position of hole many with the punching operation solving existing auto parts exists the problem of error.
The technical scheme that technical solution problem of the present invention adopts is: this part punching die comprises the top mold frame and lower mold holder that are socket-connected by guide pin bushing, described top mold frame be provided with in its lower surface two wedge faces relative carve block, be provided with red pin in carving between block described in two; Described lower mold holder is provided with two slide blocks by runner block, and two described slide blocks are equipped with in outside carves with described wedge face of carving block the wedge chute connect mutually, and two described slide blocks are equipped with a corresponding side blow pin in inner side; Described lower mold holder is equipped with blowing locating piece below described red pin.
In above-mentioned part punching die technical scheme, technical scheme can also be more specifically: the limited block being equipped with described slide block in described lower mold holder both sides, is provided with the extension spring be connected with described slide block at described limited block.
Further: two wedge faces of carving block described in two are relative splayed.
Further: another relative both sides of described slide block are provided with dovetails, and described runner block is provided with the dovetail groove slipped mutually with the dovetails of described slide block.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: 1, carve block and red pin because top mold frame is provided with two, lower mold holder is provided with the slide block of two inner band side blow pins, during work, the block of carving of top mold frame drives two slide blocks to drive side blow pin under forcing press effect, complete punching and side punching, original two operations once completed, after completing punching, slide block resets by extension spring simultaneously; 2, saving of work and time, not only protects the positional precision in hole, also improves work efficiency, reduce production cost simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the auto parts treating punching.
Fig. 2 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
Be illustrated in figure 1 the structural representation of auto parts 8, have two hole a to be rushed and hole b in the two sides of auto parts 8 and bottom surface respectively.
Part punching die as shown in Figure 2 comprises the top mold frame 1 and lower mold holder 6 that are socket-connected by guide pin bushing 12, top mold frame 1 in lower surface be equipped with two wedge faces relative carve block 2, two two wedge faces of carving block 2 are relative splayed; Two top mold frame 1 lower surfaces of carving between block 2, red pin 9 is housed; Lower mold holder 6 points is separately equipped with two slide blocks 3 by four pieces of runner blocks 4, two slide blocks 3 are equipped with the wedge chute 3-1 carving mutually with the wedge face of carving block 2 and connect in outside, two slide blocks 3 are equipped with a corresponding side blow pin 5 in inner side, two side blow pins 5 are arranged in coaxial, and another nearly red pin 9 is cut up with a hay cutter as inner side; In another relative both sides of slide block 3, namely the both sides, front and back of the present embodiment are equipped with dovetails, and every block runner block 4 all has the dovetail groove slipped mutually with the dovetails of slide block 3; The limited block 11 of slide block 3 is all housed outside lower mold holder 6 both sides that is two, and the present embodiment is all equipped with two pieces of limited blocks 11 outside two of lower mold holder 6, and every block limited block 11 all has the extension spring 10 be connected with one piece of slide block 3; Blowing locating piece 7 is equipped with lower mold holder 6 being positioned at below red pin 9.
During work, part punching die is placed on the workbench of forcing press, be contained on blowing locating piece 7 opening down for auto parts 8, starting pressure machine, carve block 2 and drive two slide blocks 3 to drive the red pin 9 of side blow pin 5 and top mold frame 1 for two of top mold frame 1, complete the upper punching to auto parts 8 and side punching, after completing punching, slide block resets by extension spring simultaneously; 2, saving of work and time, not only protects the positional precision in hole, also improves work efficiency, reduce production cost simultaneously.
