The specific embodiment
Be example sheet metal member is carried out the pre-bending deburring below, the specific embodiment of the utility model carried out detailed explanation in conjunction with accompanying drawing 1-6.
Fig. 1 is in the sketch map under the die opening state for the pre-bending Trimming Die, and Fig. 2 is in the sketch map under the matched moulds state for the pre-bending Trimming Die, and is as depicted in figs. 1 and 2; Said pre-bending Trimming Die mainly comprises upper die and lower die; Wherein, patrix is fixed on the press ram, can move up and down with the forcing press top shoe; Counterdie is fixed on the forcing press lower bolster, and is fixed.Patrix comprises upper bolster 1; The side towards counterdie of this upper bolster 1 be disposed with upper padding plate 2, on cushion block 4 and binder body 5; Wherein, upper padding plate 2 is screwed with upper bolster 1 and is connected, and in this upper bolster 1, also is provided with spring 11 and spacer pin 12; Spring 11 usefulness think that patrix provides pressure source, and spacer pin 12 is in order to carry out spacing to binder body 5.The side towards upper bolster 1 at die shoe 6 is provided with lower bolster 7, in this die shoe 6, also be provided with to play ejector pin 14, this bullets ejector pin 14 in order to jack-up by the parts of pre-bending deburring and make it from lower bolster 7 disengagings; The side away from the patrix side at this die shoe 6 is provided with in order to die shoe 6 is formed the lower cushion block 8 and lower installation board 9 of fixed support effect.In addition; The side near the counterdie side at upper bolster 1 is provided with guide pin bushing 10; The side near the patrix side at die shoe 6 is provided with the guide pillar 13 that matches with guide pin bushing 10, and in the matched moulds process, guide pin bushing 10 can move along guide pillar 13; Can guide effect be provided for the motion of patrix, thereby upper die and lower die are cooperated accurately.On upper die and lower die, also be provided with the limited block 15 that matches, can guarantee that upper die and lower die are more accurate ordinatedly under the matched moulds state, avoid it that dislocation takes place and influence the crudy of parts.
As shown in Figure 1, the edge of corresponding binder body 5 is provided with mo(u)ld top half and inserts 3 on patrix, this mo(u)ld top half insert 3 on the end of counterdie side, a side of its adjacent binder body 5 is formed with cutting edge.As shown in Figure 2, under the matched moulds state, binder body 5 matches with the opposite face of lower bolster 7, mo(u)ld top half insert 3 be close to binder body 5 match with lower bolster 7 place the outside.As shown in Figure 3; Corresponding binder body 5 place that matches with lower bolster 7; Bight, edge at lower bolster 7 is formed with chamfering 16; This chamfering 16 is the inclined plane that tilts towards away from the patrix side direction, and it is parallel to the length on the matched moulds direction perpendicular to the length on the matched moulds direction greater than it, thereby helps parts are realized the pre-bending operation.
The operation principle that parts carry out pre-bending deburring operation is described to using above-mentioned pre-bending Trimming Die below in conjunction with Fig. 1-Fig. 6.
Like Fig. 1 and shown in Figure 4, last process components is placed on the lower bolster 7 of counterdie, patrix along with press ram towards near counterdie side direction motion, the peristome of binder body 5 contacts with parts on being arranged on lower bolster 7.
Like Fig. 2 and shown in Figure 5, patrix is in descending process, and binder body 5 is pushed down parts and avoided parts to be moved so that parts are fixed on the lower bolster 7, and counterdie and patrix are in the matched moulds state.
As shown in Figure 6, it is descending that patrix continues, and mo(u)ld top half is inserted and 3 continued to press down parts, and then parts bend along chamfering under mo(u)ld top half is inserted 3 effect, thereby parts are realized that pre-bending processes; Mo(u)ld top half is inserted and 3 parts is being realized the bending continued is descending, via the cutting edge that mo(u)ld top half is inserted on 3 parts is realized shearing, thereby parts are accomplished the deburring operation.
The above is merely the preferred embodiment of the utility model, not in order to restriction the utility model.In a word, all within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
[0028] for example, in the above-described embodiments, said chamfering is a ramp structure, yet not limited thereto, and this chamfering also can be the bigger arc structure of curvature.
