Abstract
The invention discloses a perforating die structure for a ribbon retainer. The perforating die structure comprises a lower die holder, a female die, a steel ball, an upper die holder, a base plate, a steel ball seat, a material-ejecting spring and a push-out rod. A screw above the lower die holder is connected with the female die. An inner diameter controller is arranged in the female die. The steel ball seat, the base plate, the upper die holder are sequentially disposed above the female die. The steel ball seat, the base plate and the upper die holder are sequentially connected. The steel ball is disposed between the female die and the steel ball seat. The push-out rod is arranged in the steel ball seat. A pushing device is arranged at the upper end of the push-out rod. A die structure is simplified, die production cost is reduced, processing accuracy and product quality are guaranteed, and working efficiency is improved.
Description
Technical field
The present invention relates to a kind of perforating die structure, be specifically related to the perforating die structure for ribbon retainer.
Background technology
The ribbon retainer production technology mainly is made up 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 influences the ribbon retainer surface quality is pressure wound and burr, and because 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, have a strong impact on quality and manufacturing schedule.Therefore in process, the punching press link also must careful attention.
Problems such as existing punching die part is more, and mating surface is many, and the multilayer reference for assembling makes mould assembling back accumulated error big, does not guarantee the punch clearance of little clearance blanking, and generation burr and hole site be inclined to one side during punching.
Summary of the invention
The present invention relates to the parts perforating die structure that is used for ribbon retainer less, simple in structure, solved and be easy to generate pressure wound and Burr Problem because the punching die part is more.
Be used for the perforating die structure of ribbon retainer, comprise material returned ring, convex mould base, punch, die, reference column, upper bolster, die shoe; Described die is positioned at the die shoe top and links to each other with die shoe by screw, is provided with material returned ring, convex mould base, upper bolster on the described die successively, and die, material returned ring link to each other by reference column with convex mould base; Described punch is arranged in the convex mould base, and the tip, bottom of described punch extends in the material returned ring.
Described punch is of a size of 10-50mm.
Also be provided with backing plate between described upper bolster and the convex mould base.
Also be provided with groove in the described die, groove is positioned under the punch.
Described groove is bigger than the bottom tip size of punch.
The present invention compared with prior art has the following advantages and beneficial effect:
The present invention has reduced workpiece, makes the mating surface of perforating die structure reduce, thereby has reduced rigging error, and reference column is acted directly on convex mould base and the die, guarantees to guide accurate, guarantees each no gap of parts cooperation, has greatly reduced the punching burr.
Description of drawings
Fig. 1 is structure chart of the present invention.
The name of Reference numeral correspondence is called: 1-material returned ring, 2-convex mould base, 3-reference column, 4-backing plate, 5-punch, 6-die, 7-upper bolster, 8-die shoe, 9-groove.
The specific embodiment
The present invention is described in further detail below in conjunction with embodiment, but embodiments of the present invention are not limited thereto.
Referring to Fig. 1, be used for the perforating die structure of ribbon retainer, comprise material returned ring 1, convex mould base 2, punch 5, die 6, reference column 3, upper bolster 7, die shoe 8; Described die 6 is positioned at die shoe 8 tops and links to each other with die shoe 8 by screw, is provided with material returned ring 1, convex mould base 2, upper bolster 7 on the described die 6 successively, and die 6, material returned ring 1 and convex mould base 2 link to each other by reference column 3; Described punch 5 is arranged in the convex mould base 2, and the tip, bottom of described punch 5 extends to 1 li on material returned ring.
During punching, under the 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 reference column 3, continue to press down upper bolster 7, and punch 5 and die 6 are sheared punchings.After the die sinking, material returned ring 1 is backed off retainer from punch 5, finish punching.
Similar referring to Fig. 1 and embodiment 1, 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 the convex mould base 2.
Also be provided with groove 9 in the above-mentioned die 6, groove 9 is positioned under the punch 5, and above-mentioned groove 9 is bigger than the bottom tip size of punch 5, when 5 pairs of ribbon retainer punchings of punch, can just embed 9 li of grooves, finishes punching.
