Description
Technical field
The utility model relates to a kind of mould, particularly a kind of no cutting edge mould that has mounting hole, and it is a upper and lower mould assembly, mainly is applicable to the manufacturing of square steel pipe in the body-building apparatus.
Background technology
In the prior art, the manufacturing of body-building apparatus needs square steel pipe usually, and will be on square steel pipe the punching press waist-shaped hole, the specification requirement of punching press waist-shaped hole is that the distance between two waists must be consistent with the endoporus length of side of square steel pipe.And prior art is with general upper and lower mould structure punching press square tube waist circular apertures, and counterdie can't form cutting edge, can't punch forming; Can only carry out milling machine processing with machinery again, time-consuming, increase cost, do not satisfy desirable effect.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and provides a kind of reasonable in design, the no cutting edge mould that has mounting hole that waist-shaped hole can be one time punching molded.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this no cutting edge mould that has mounting hole comprises mold and bed die, and this mold and bed die coupling is characterized in that:
Described mold comprises patrix, location-plate and staking punch, and they are fixing by welding; And an end of staking punch is the inclined-plane;
Described bed die comprises counterdie, movable plug, positioning seat, stationary core rod and fixed head; This activity plug, positioning seat and fixed head all are fixed on the counterdie, and have fixedly cutting edge on the stationary core rod, have movable cutting edge on the movable plug, and described fixedly cutting edge is corresponding with movable cutting edge, and form waist-shaped hole.
As preferably, the utility model also is provided with deck in described bed die, also have draw-in groove on the described movable plug, and this draw-in groove snaps in the deck just.
As preferably, patrix described in the utility model is made up of the upper, middle and lower, and top and middle part are circular, and upper part diameter is less than the diameter at middle part.
The utility model compared with prior art, have following positive effect: reasonable in design, the movable plug of counterdie structure applications, plug are inserted in square steel pipe and endoporus coincide, make two waists of waist-shaped hole not have cutting edge cutting punching press, one-shot forming in the punching press of square steel pipe waist-shaped hole; Thereby saving of work and time, cost is low, and result of use is good.

The specific embodiment
Referring to Fig. 1-Fig. 5, the utility model mainly is made up of mold I and bed die II, this mold I and bed die II coupling.Wherein: mold I comprises patrix 1, location-plate 2 and staking punch 3; Bed die II comprises counterdie 4, movable plug 5, movable cutting edge 6, draw-in groove 7, deck 8, positioning seat 9, stationary core rod 10, fixedly cutting edge 11, fixed head 12, fixed screw 13 and set bolt 14.15 is square tube to be processed.
Patrix 1 of the present utility model, location-plate 2 and staking punch 3 are weldingly fixed on together.Wherein: patrix 1 can be made up of top 1-1, middle part 1-2 and bottom 1-3, and they are fixed into one; Top 1-1 and middle part 1-2 are circular, and the diameter of top 1-1 is less than the diameter of middle part 1-2.
Deck 8 of the present utility model, positioning seat 9 can be weldingly fixed on the counterdie 4; Stationary core rod 10 has fixedly 11, two fixed heads 12 of cutting edge and stationary core rod 10 is clamped and fix with set bolt 14, and two fixed head 12 usefulness fixed screws 13 are fixed on the counterdie 4; Have movable cutting edge 6 and draw-in groove 7 on the movable plug 5, movable plug 5 is inserted in positioning seat 9 to control the move left and right of movable plug 5, and draw-in groove 7 snaps in the deck 8 just, to control moving forward and backward of movable plug 5; Movable cutting edge 6 and fixedly cutting edge 11 form the waist-shaped hole 20 that two waists do not have cutting edge just; When square tube 15 to be processed is inserted in movable plug 5 and the stationary core rod 10, cover just on the waist-shaped hole 20 of no cutting edge.
Among the bed die II of the present utility model, between movable plug 5 and the stationary core rod 10, and the movable cutting edge 6 and the coupling that fixedly fits like a glove between the cutting edge 11, form the waist-shaped hole 20 that two waists do not have cutting edge; Draw-in groove 7 snaps in the deck 8 just and with the move left and right that positioning seat 9 is fixed movable plugs 5, movable plug 5 can not moved in press work.
Mold I of the present utility model, design has location-plate 2 and staking punch 3, and staking punch 3 is inclined-plane 31, in punching course:
The one, the staking punch 3 that is inclined-plane 31 impacts square tube 15 to be processed, contact with fixing cutting edge 11 punching presses, and the punching press contact is little, can arbitrary deformation behind the square tube 15 impact pressurizeds to be processed.
The 2nd, the staking punch 3 on inclined-plane 31 is pressed into no cutting edge place, is forficiform with the facade of square tube 15 to be processed and is pressed into, and realizes no cutting edge punching press.
The 3rd, the staking punch 3 that is inclined-plane 31 contacts with movable cutting edge 6 punching presses, forms hole, punch forming hole 20.
Specific embodiment described in this specification, as long as its part undeclared concrete shape and size, then this part can be Any shape and the size that adapts with its structure; Simultaneously, the part title of getting also can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model patent.
