Description
Technical field
The utility model relates to Bending Mould technical field, and especially a kind of 90 ° of being applied in the progressive die open adjustment and acute angle bending structure outward.
Background technology
The progressive die refers to that forcing press is in a punching stroke, and a secondary mould completes with several different station the cold stamping punch die of multi-step forming processes simultaneously, and the every punching press of mould completes once, and material strip fixed-distance moving once, completes to product.The progressive die is widely used, and contain multiple field, formed precision is high, and production efficiency is high, safety and stability.Structures such as having have employed line ball to 90 ° outer and acute angle bending and molding in prior art, put back to bullet, slide block is shaping, plays a line ball and not only will obtain client's confirmation, also easily burst apart during bending; Put back to bullet mode also to need to add shaping station again to adjust, add mold station, processing cost; Slide block mode processed complex, cost is higher, and after slide block bursts apart, maintenance cost is higher; Above-mentioned existing structure splicing is complicated, and repair a die inconvenience, and cost is higher, produces stable not.
Utility model content
The applicant is for the shortcoming in above-mentioned existing production technology, and provide a kind of progressive die 90 ° adjustment and acute angle bending structure outward, thus reduce difficulty of processing, save processing cost, simple and convenient assembly, forming stability is good, conveniently repairs a die, administration measure.
The technical scheme that the utility model adopts is as follows:
A kind of progressive die 90 ° is adjustment and acute angle bending structure outward, comprise fixing mold insert, described fixing mold insert one end offers counterbore, and jigger pin is installed in described counterbore bottom, described counterbore top is provided with set screw, and described set screw is connected by spring with between jigger pin; Install below described fixing mold insert and swing punching pin, the structure of described swing punching pin is: described swing punching pin is provided with outwardly drift in the middle part of end face, the upper end face of described drift both sides is inclined-plane, described swing punching pin lower end right side opening is provided with square breach, and described square indentation, there is provided with transition arc; Also comprise counterdie and enter son, described counterdie enters sub-left end and offers the bending structure matched with the square breach swinging punching pin.
Further improvement as technique scheme:
The recess with drift rotatable engagement is offered in the middle part of described fixing mold insert bottom surface.
The inclined-plane of described swing punching pin is downward-sloping from the inside to the outside, and the value range of angle of inclination b is 5 °-15 °.
The beneficial effects of the utility model are as follows:
Swing punching pin of the present utility model and fixing mold insert easy to process, both matching parts slidably, utilize and swing the swing of punching pin and complete punch forming to workpiece; Utilize jigger pin and swing the reset of punching pin, can easy-unloading; After swinging the wearing and tearing of punching pin Long-Time Service, can facilitate at any time, repair a die conveniently; Compact overall structure, not only can reduce cloth station, also can reduce Mould Machining cost, improves formed precision.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1 and Figure 2, the progressive die 90 ° adjustment and the acute angle bending structure outward of the present embodiment, comprises fixing mold insert 3, fixing mold insert 3 one end offers counterbore, jigger pin 4 is installed in counterbore bottom, and counterbore top is provided with set screw 1, is connected between set screw 1 with jigger pin 4 by spring 2; Install below fixing mold insert 3 and swing punching pin 5, as shown in Figure 3, Figure 4, the structure swinging punching pin 5 is: swing on punching pin 5 and be provided with outwardly drift 501 in the middle part of end face, the upper end face of drift 501 both sides is inclined-plane 503, swing punching pin 5 lower end right side opening and be provided with square breach, square indentation, there is provided with transition arc 502; Also comprise counterdie and enter son 7, counterdie enters sub 7 left ends and offers the bending structure 701 matched with the square breach swinging punching pin 5, and bending structure 701 is provided with angle a, and angle a bending angle needed for product is adjusted.
The recess with drift 501 rotatable engagement is offered in the middle part of fixing mold insert 3 bottom surface.
The inclined-plane 503 swinging punching pin 5 is downward-sloping from the inside to the outside, and the value range of slanted angle b is 5 °-15 °.
Utility model works process is as follows:
First, workpiece 6 is delivered to counterdie and enters sub 7 upper surfaces, swing punching pin 5 and counterdie enter son 7 and are in released state; Then, punch press is descending, mould closes gradually, fixing mold insert 3 moves down along with punch press, workpiece pressing 6 gradually, swing punching pin 5 and coordinate swing counterclockwise in the described recess of fixing mold insert 3, jigger pin 4 starts up, until the inclined-plane, right side 503 swinging punching pin 5 abuts with the bottom surface of fixing mold insert 3, workpiece 6 punch forming under the transition arc 502 and counterdie that swing punching pin 5 enter the acting in conjunction of the bending structure 701 of son 7; Finally, punch press is up, and jigger pin 4 withstands and swings inclined-plane 503 on the right side of punching pin 5 under the effect of spring 2, and swing punching pin 5 and reset along clockwise oscillation, bending process completes, and workpiece 6 completes discharging, carries out next step operation.
The utility model utilization swing punching pin 5 has coordinated bending process with fixing mold insert 3, and swing punching pin 5 Flexible Reset good, it is convenient to change; Fixing mold insert 3 is easy to process, simple for structure, and forming stability is good; Both cooperatively interact slips, and without interference, cost is low, and it is convenient to keep in repair.
Jigger pin 4 in the utility model is convenient to carry out the reset to swinging punching pin 5, convenient de-material.
The utility model reduces cloth station, and disposable at an angle of 90 complete and acute angle bending and molding, effectively reduces die cost, improves punching precision, saves opening period.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range, see claim, within protection domain of the present utility model, can do any type of amendment.
