Abstract
The invention belongs to the field of dies, and particularly discloses an orifice punching die of a holder. The orifice punching die comprises an upper die base, a lower die base, female die bodies and male die bodies; the lower die base is connected with the multiple male die bodies, the male die bodies are matched with the female die bodies, and a guide column is connected to the lower die base and connected with the upper die base; the orifice punching die further comprises a connecting rod, an ejection rod and a male die fixing plate, the connecting rod is connected with the upper die base, and a piece pushing block is arranged below the connecting rod; and springs are arranged at the lower portions, connected with the upper die base, of the piece pushing block and the ejection rod and connected with the male die fixing plate, and the male die fixing plate is connected with the male die bodies. According to the orifice punching die, one-time punching can be achieved, and the working efficiency can be improved.
Description
Technical field
The present invention relates to mould, be specifically related to a kind of retainer and rush fenestra mould.
Background technology
Taper roll bearing in automotive transmission is the strength member of formed automobile, has material impact to automotive performance.Bearing generally comprises outer ring, inner ring, rolling element and retainer four part.Retainer refers to and partly wraps up all or part of rolling element, and the bearing parts thereupon moved, in order to separation roller, usually also guide rolling element and hold it in bearing.The precision of the taper retainer in bearing and quality can affect rolling situation and the bearing clearance of roller, directly affect the performance of bearing, thus affect further the situations such as the safe operation of automobile and noise.And mould is as the direct equipment producing retainer, mould structure reasonable in design seems and is even more important.Retainer fenestra stamping-out traditional handicraft be generally with the single hole-punching method of mould one by one retainer rush fenestra, like this, mould structure is simple, but fenestra axial location precision is low, unanimously meet difficulty when installing roller, easy appearance rotates inflexible phenomenon, causes automobile occur larger noise in motion or run slack phenomenon.
Summary of the invention
Object of the present invention disposablely can rush multiple hole providing one, and the retainer of increasing work efficiency rushes fenestra mould.
For achieving the above object, technical scheme of the present invention is as follows: a kind of retainer rushes fenestra mould, comprises upper bolster, die shoe, die and punch, and described die shoe is connected with multiple punch; Described punch coordinates with die, and described die shoe is connected with guide pillar, and described guide pillar is connected with upper bolster; Also comprise connecting rod, push rod and punch retainer, described connecting rod is connected with upper bolster, and described connecting rod has ejector block; Described ejector block is connected described upper bolster bottom and is provided with spring with push rod, described spring is connected with punch retainer, and described punch retainer is connected with punch.
Operation principle of the present invention and beneficial effect are: retainer is placed in die, and upper bolster presses down, and drive punch to come downwards to bottom retainer, punch moves up and down end; Upper bolster continues to move downward, and drive connecting rod descending, the taper-face contact of the conical surface and punch under connecting rod, forces punch to move from inside to outside and realize punching.After stamping-out terminates, upper bolster drives connecting rod up, and punch is drawn close to center under spring force simultaneously, exits workpiece; Whole upper bolster is up, makes punch up thus returns in die, finally utilizes Spring driving push rod to eject product.The present invention includes multiple mould to carry out processing to retainer simultaneously and disposablely can rush multiple hole, increase work efficiency.
Further, described top mold frame is provided with guide pin bushing, and guide pin bushing coordinates with guide pillar, is guide pillar guiding.
Further, described punch cutting edge is oblique sword, and punch is that oblique sword can reduce blanking pressure, improves die life.
Further, described punch angle of relief is 1 ~ 3 °, if angle of relief is excessive, and cutting edge rapid wear.
Accompanying drawing explanation
Fig. 1 is the structural representation that retainer of the present invention rushes fenestra Die Embodiment.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: die shoe 1, upper bolster 2, spring 3, connecting rod 4, push rod 5, punch 6, ejector block 7, guide pillar 8, punch retainer 9, guide pin bushing 10, die 11.
Embodiment is substantially as shown in Figure 1: a kind of retainer rushes fenestra mould, comprises upper bolster 2, die shoe 1, die 11 and punch 6, and die shoe 1 is connected with 14 punch 6; Punch 6 coordinates with die 11, and die shoe 1 is welded with guide pillar 8, and guide pillar 8 and upper bolster 2 are slidably connected; Also comprise connecting rod 4, push rod 5 and punch retainer 9, connecting rod 4 is connected with upper bolster 2, and connecting rod 4 inserts in the middle part of upper bolster 2, and upper bolster 2 bottom is connected with spring 3, and spring 3 punch retainer 9 connects, and punch retainer 9 is connected with punch 6; Connecting rod 4 has ejector block 7; Ejector block 7 is threaded with push rod 5.Mould bases is also fixed with guide pin bushing 10, and guide pin bushing 10 coordinates with guide pillar 8, for guide pillar 8 leads.Punch 6 cutting edge is oblique sword, and punch 6 can reduce blanking pressure for oblique sword, improves die life.Punch 6 angle of relief is 3 °, if angle of relief is excessive, and cutting edge rapid wear.
Retainer is placed in die 11, upper bolster 2 presses down, and drive punch 6 to come downwards to bottom retainer, punch 6 moves up and down end; Upper bolster 2 continues to move downward, and drive connecting rod 4 descending, the taper-face contact of connecting rod 4 times conical surfaces and punch, forces punch 6 to move from inside to outside and realize punching.After stamping-out terminates, upper bolster 2 drives connecting rod 4 up, and punch 6 exits workpiece under spring force simultaneously; Whole upper bolster is up, makes punch 6 up thus returns in die 11, finally utilizing spring 3 to drive push rod to eject product.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
