Description
Technical field
The utility model relates to mould, is specifically related to a kind of retainer and rushes 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.
Utility model content
The purpose of this utility model disposablely can rush multiple hole providing one, and the retainer of increasing work efficiency rushes fenestra mould.
For achieving the above object, the technical solution of the utility model 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 utility model 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 utility model comprises multiple mould to carry out processing to retainer simultaneously and disposablely can rush multiple hole, increases work efficiency.
Further, described upper bolster 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 the utility model retainer rushes fenestra Die Embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
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.Upper bolster 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 embodiment of the present utility model, 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 the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.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.
