Abstract
The utility model discloses a punching die structure of a ribbon cage. The punching die structure comprises a lower die base, a female die, a steel ball, an upper die base, a base plate, a steel ball base, a material ejection spring and a push-out rod, wherein a screw above the lower die base is connected with the female die, an inner-diameter controller is arranged in the female die, the steel ball base, the base plate and the upper die base are sequentially arranged above the female die, and the steel ball base, the base plate and the upper die base are connected in sequence. The steel ball is placed between the female die and the steel ball base, the push-out rod is arranged in the steel ball base, and the upper end of the push-out rod is provided with a pushing device. According to the punching die structure of the ribbon cage, the die structure is simplified, die manufacturing cost is reduced, machining accuracy and product quality are guaranteed, and working efficiency is improved.
Description
Technical field
The utility model relates to a kind of perforating die structure, is specifically related to a kind of perforating die structure of ribbon retainer.
Background technology
The ribbon retainer production technology mainly is comprised of punch process operations such as cutting ring, shaping, shaping, punching.
The punching operation is the finishing operation of large-scale ribbon retainer machining.The principal element that affects the ribbon retainer surface quality is pressure wound and burr, and due to the particularity of punch process, these two kinds of phenomenons all are difficult in time being detected, in case go wrong, just must reprocess or sanding thorn, pick the retainer of pressure wound, having a strong impact on quality and manufacturing schedule.Therefore in process, the punching press link also must careful attention.
The problems such as existing punching die part is more, and mating surface is many, and after the multilayer reference for assembling makes mould assembling, accumulated error is large, does not guarantee the punch clearance of little clearance blanking, and during punching generation burr and hole site be inclined to one side.
The utility model content
The utility model has related to the perforating die structure of parts a kind of ribbon retainer less, simple in structure, has solved and easily produces pressure wound and Burr Problem because the punching die part is more.
A kind of perforating die structure of ribbon retainer, comprise material returned ring, convex mould base, punch, die, locating dowel, upper bolster, die shoe; Described die is positioned at the die shoe top and by screw, with die shoe, is connected, and is provided with successively material returned ring, convex mould base, upper bolster on described die, and die, material returned ring are connected by locating dowel with convex mould base; Described punch is arranged in convex mould base, and the tip, bottom of described punch extends in material returned ring.
Described punch is of a size of 10-50mm.
Also be provided with backing plate between described upper bolster and convex mould base.
Also be provided with groove in described die, groove is positioned under punch.
Described groove is larger than the bottom tip size of punch.
The utility model compared with prior art has the following advantages and beneficial effect:
The utility model has reduced workpiece, makes the mating surface of perforating die structure reduce, thereby has reduced rigging error, and locating dowel is acted directly on convex mould base and die, guarantee to guide accurate, guarantee that each parts coordinate gapless, have greatly reduced punching burr.
Description of drawings
Fig. 1 is structure chart of the present utility model.
The name that Reference numeral is corresponding is called: 1-material returned ring, 2-convex mould base, 3-locating dowel, 4-backing plate, 5-punch, 6-die, 7-upper bolster, 8-die shoe, 9-groove.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment, but embodiment of the present utility model is not limited to this.
Embodiment 1
Referring to Fig. 1, a kind of perforating die structure of ribbon retainer, comprise material returned ring 1, convex mould base 2, punch 5, die 6, locating dowel 3, upper bolster 7, die shoe 8; Described die 6 is positioned at die shoe 8 tops and by screw, with die shoe 8, is connected, and is provided with successively material returned ring 1, convex mould base 2, upper bolster 7 on described die 6, and die 6, material returned ring 1 and convex mould base 2 are connected by locating dowel 3; Described punch 5 is arranged in convex mould base 2, and the tip, bottom of described punch 5 extends to 1 li, material returned ring.
During punching, under die opening state, punching ribbon retainer not is placed on the die 6 of punching die, presses down upper bolster 7, convex mould base 2, material returned ring 1, die 6 are located under the effect of locating dowel 3, continue to press down upper bolster 7, and punch 5 and die 6 are sheared punchings.After die sinking, material returned ring 1 is backed off retainer from punch 5, complete punching.
Embodiment 2
Referring to Fig. 1, and embodiment 1 is similar, and difference is:
Above-mentioned punch 5 is of a size of 10-50mm.
Also be provided with backing plate 4 between above-mentioned upper bolster 7 and convex mould base 2.
Also be provided with groove 9 in above-mentioned die 6, groove 9 is positioned under punch 5, and above-mentioned groove 9 is larger than the bottom tip size of punch 5, when 5 pairs of ribbon retainer punchings of punch, can just embed 9 li of grooves, completes punching.
