The specific embodiment
As shown in Figure 1, a kind of unsteady shaping mould of the present invention, comprise cope match-plate pattern 6, patrix cutter piece 4, lower bolster 9, lower die cutter piece 11, guiding parts and work/deposit limiter 1, patrix cutter piece 4 is fixed on the cope match-plate pattern 6, lower die cutter piece 11 is fixed on the lower bolster 9, be provided with the guide pillar 8 that leads for patrix cutter piece 4 at lower bolster 9, and be provided with the guide pin bushing 7 that cooperates with guide pillar 8 at cope match-plate pattern 6.Because the mould that exists in the prior art can't produce the U-shaped stamping parts 12 that has negative angle, but many problems that the method that adopts the bulk-breaking assembly unit is brought again, in order to produce the U-shaped stamping parts 12 of band negative angle, this unsteady shaping mould also comprises a horizontal unsteady dressing blade piece 3 between patrix cutter piece 4 and lower die cutter piece 11, at unsteady dressing blade piece 3, patrix cutter piece 4 and lower die cutter piece 11 be provided with match make it to produce the negative angle forming section of negative angle for skewed extruding U-shaped stamping parts 12, need be stamped on the U-shaped stamping parts 12 horizontal negative angle forming sections that are enclosed within on this unsteady dressing blade piece 3 that have negative angle, patrix cutter piece 4 moves up and down, the negative angle forming section on the patrix cutter piece 4 and the negative angle forming section on the lower die cutter piece 11 extruding U-shaped stamping parts 12 that matches with negative angle forming section on the unsteady dressing blade piece 3.Be illustrated in figure 2 as match with patrix cutter piece 4 and lower die cutter piece 11 cutaway view of work of the dressing blade piece 3 that floats, negative angle forming section on the patrix cutter piece 4 upper and lower mould cutter pieces 11 is a clinoplain, the float end face of negative angle forming section of dressing blade piece 3 and bottom surface parallels with clinoplain on the adjacent patrix cutter piece 4 upper and lower mould cutter pieces 11 respectively, being shaped as towards a side of the longitudinal section of the negative angle forming section of the unsteady dressing blade piece 3 of formation is open-shaped, and it is contraction-like that opposite side is.The clinoplain at unsteady dressing blade piece 3 tops is parallel with the clinoplain of patrix cutter piece 4, and the bottom angled plane of the dressing blade piece 3 that floats is parallel with the clinoplain of lower die cutter piece 11, and the angle of inclination on all inclined planes is determined according to the negative angle of U-shaped stamping parts 12.U-shaped stamping parts 12 levels are horizontal to be enclosed within on the dressing blade piece 3 that floats, and is fastened on the sidepiece of the dressing blade piece 3 that floats by product keeper 5, has the two sides of U-shaped stamping parts 12 of negative angle and the upper and lower surface of unsteady dressing blade piece 3 after being stamped and fits.By this kind structure, well solved the problem that can not produce the U-shaped stamping parts 12 that has negative angle that exists in the prior art, mould structure is simple, can be one time punching molded, the production efficiency height has been avoided the accumulated tolerance that adopts the bulk-breaking assembly unit to produce, promoted the product precision, reduce frock quantity, shortened technological process, reduced the control difficulty of production cost and production and quality.
Shape according to stamping parts processes dressing blade piece 3 patrix cutter piece 4 and the lower die cutter pieces 11 that float, because the U-shaped stamping parts 12 after the shaping has negative angle, can't directly take out from the dressing blade piece 3 that floats, need process at unsteady dressing blade piece 3 and get hopper, as Fig. 1, this gets the adjacent setting of negative angle forming section on hopper and the unsteady dressing blade piece 3, get hopper and be dressing blade piece 3 upper and lower surfaces and patrix cutter piece 4 and lower die cutter piece 11 rectangular recess that forms of certain space at interval in the vertical that floats, the stamping parts that shaping is finished needs earlier past being displaced sideways getting the hopper place to withdraw from mould.
After this mould is finished shaping work, for the dressing blade piece 3 that floats is automatically reset, as shown in Figure 1, one back-moving spring 10 is set, it passes the bottom that lower die cutter piece 11 1 ends are against the dressing blade piece 3 that floats, the other end is against on the lower bolster 9, is provided with the hole that back-moving spring 10 passes at lower die cutter piece 11.Back-moving spring 10 is set, and when 4 backhauls of patrix cutter piece, float dressing blade piece 3 and U-shaped stamping parts 12 automatically reset under the effect of back-moving spring 10, and can also play certain cushioning effect when unsteady dressing blade piece 3 descending shapings.
For unlikely offside after the dressing blade piece 3 that floats is automatically reset, the variable locating part of a diameter is set, a part of diameter of its body is big, and another part diameter is little.Lower bolster 9 arrange a miner diameter end up, bigger diameter end stepped hole down, the top of locating part is that path partly passes stepped hole and fixedlys connected with unsteady dressing blade piece 3, the bottom namely moves up and down in the bigger diameter end of part at stepped hole greatly, namely be limited in the hole, big footpath of stepped hole, the dressing blade piece 3 that prevents from floating is offside when upwards resetting.As shown in 1, this locating part is a turnbuckle, and turnbuckle passes lower die cutter piece 11, and its screwed end is fastenedly connected in the bottom of floating dressing blade piece 3, and its bolt head is limited in the hole, big footpath of stepped hole.
As shown in Figure 1, guiding parts also comprises the inner guiding post 2 that is used for unsteady dressing blade piece 3 guiding that is located on the lower bolster 9, and the motion of the dressing blade piece 3 that floats is by inner guiding post 2 guiding.
The operation principle of this unsteady shaping mould:
U-shaped stamping parts 12 to be punched is mounted on dressing blade piece 3 sides of floating, is in above it between float dressing blade piece 3 and the patrix cutter piece 4, be between unsteady dressing blade piece 3 and the lower die cutter piece 11 below it.When mold work, patrix cutter piece 4 moves downward, and contacts the top of U-shaped stamping parts 12 earlier and it is close on the dressing blade piece 3 that floats; Patrix cutter piece 4 continues to move downward, and drives U-shaped stamping parts 12 and unsteady dressing blade piece 3 and moves downward, and back-moving spring 10 is compressed, and the motion of the dressing blade piece 3 that floats is by inner guiding post 2 guiding; When touching lower die cutter piece 11 and floated dressing blade piece 3 and lower die cutter piece 11 below the U-shaped stamping parts 12 gradually and press, the negative angle forming section of patrix cutter piece 4, lower die cutter piece 11 is pressed on U-shaped stamping parts 12 on the negative angle forming section of the dressing blade piece 3 that floats, and it is pressed into required shape; After shaping was finished, patrix cutter piece 4 returned and moves upward, and U-shaped stamping parts 12 and unsteady dressing blade piece 3 also move upward under the spring force effect, break away from lower die cutter piece 11 gradually; Patrix cutter piece 4 continues to move upward, and U-shaped stamping parts 12 and unsteady dressing blade piece 3 are tightened up bolt restriction and stop motion, and patrix cutter piece 4 continues to move upward and breaks away from U-shaped stamping parts 12 and unsteady dressing blade piece 3 fully.The U-shaped stamping parts of finishing because of shaping 12 has negative angle, can't be directly takes out from the dressing blade piece 3 that floats, and needs earlier to withdraw from mould toward being displaced sideways getting the hopper place.
By reference to the accompanying drawings the present invention has been carried out exemplary description above; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
