Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 6, the utility model provides a punching die cutter body restoration subassembly that breaks, including main frame 1 and punching die cutter body 6, the outside of main frame 1 is provided with two rows of screw holes 12, and screw hole 12 has bottom plate 2 and enhancement strip 3 through first hexagon socket head cap screw 5 and 4 fixed mounting of first gasket, and four first through-holes 10 have been seted up in the outside of bottom plate 2, and first through-hole 10 is fixed with punching die cutter body 6 and punching die underframe 9 through second hexagon socket head cap screw 7 and second gasket 8, and two rows of drilling 11 have been seted up in the outside of bottom plate 2.

Through main frame 1, a fastening frame subassembly can be constituteed to bottom plate 2 and enhancement strip 3, the fastening frame is designed into the subassembly formula and is designed into the integral type, can save material, reduce the amount of processing by a wide margin, reduce manufacturing cost, shorten manufacturing time, fastening frame subassembly each part is prepared the back, assemble them together, imbed the die cutter body of fracture into fastening frame subassembly main frame 1 inboard again, simultaneously because be equipped with the chamfer to main frame 1 suitable for reading, the die cutter body 6 of being convenient for is leading-in, reuse second hexagon socket head cap screw 7 is fixed the fastening frame to die underframe 9 after fixing the die cutter body 6 of fracture with fastening frame subassembly, the service function of the die cutter body 6 of fracture has just been repaired completely at this moment.

Wherein, the thickness of main frame 1 is 45mm, and the thickness of bottom plate 2 is 10mm, and the thickness of strengthening strip 3 is 28mm, and main frame 1, bottom plate 2 and strengthening strip 3 all adopt 45# steel to make.

Through the design of the main frame 1, the bottom plate 2 and the reinforcing strips 3, the 45# steel is low in price and good in processing performance, and parts made of the 45# steel have high strength and deformation resistance.

The size of the matching part of the main frame 1 and the die cutter body 6 takes the actual size of the die cutter body 6 as a reference, and the tolerance with the deviation of-0.01 mm and the deviation of-0.08 mm is adopted.

Through the design of the main frame 1, the size of the inner opening is controlled when the main frame 1 is machined, the interference with the cutter body is ensured during assembly, but the interference cannot be large, the interference is large, the assembly is difficult, the secondary fracture of the punch cutter body 6 can be caused by pounding the punch cutter body 6 with great force during assembly, and the interference is more reasonable from 0.01mm to 0.10 mm.

Wherein, the punch die cutter body 6 is embedded into the inner side of the main frame 1, and the punch die cutter body 6 is in interference fit with the main frame 1.

Through the cooperation between the die cutter body 6 and the main frame 1, the die cutter body 6 is more stably embedded, and the cracked knife edge can be folded together.

The upper opening of the main frame 1 is provided with a chamfer, the number of the reinforcing strips 3 is two, and the outer sides of the reinforcing strips 3 are provided with a row of second through holes 13.

The chamfer angle that sets up through the main frame 1 upper mouth (also can set up the chamfer angle to four outer arriss of lower extreme of die cutter body 6) to be convenient for leading-in the inboard of main frame 1 to the die cutter body 6 of fracture, through the design of strengthening strip 3, two front and back strengthening strip 3's effect is in order to improve the rigidity of fastening frame subassembly, prevent under the punching force effect, the fastening frame is at die underframe 9 front and back position downward deformation, strengthen strip 3 simultaneously and be the discarded template spare part of direct utilization, the direct utilization of discarded object totally.

The threaded holes 12 are not processed into through holes, so that the upper surface of the main frame 1 is complete, the upper surface and the lower surface of the main frame 1 are not processed, the two side surfaces and the front surface and the rear surface can be processed without processing, and burrs are removed by an angle grinder.

The utility model discloses a theory of operation and use flow:

firstly, a fastening frame component can be formed by matching the main frame 1, the bottom plate 2 and the reinforcing strips 3 with the second inner hexagon screws 7 and the first inner hexagon screws 5, then, a cracked die cutter body is embedded into the fastening frame component main frame 1, meanwhile, because the upper opening of the main frame 1 is provided with a chamfer angle, the die cutter body 6 can be conveniently led in, because the die cutter body 6 has high hardness and high brittleness, a copper rod needs to be used for lightly knocking during assembly, a big hammer cannot be used for hitting again, so that the secondary fracture caused by the repeated knocking is prevented, after the cracked die cutter body 6 is fixed by the fastening frame component, the fastening frame is fixed on the die bottom frame 9 by the second inner hexagon screws 7, and thus, the use function of the cracked die cutter body 6 is completely repaired.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
