Abstract
The invention discloses a sizing die structure for a holder. The sizing die structure comprises a lower die holder, a lower die, a steel ball, an upper die holder, a backing board, a steel ball seat, a material ejection spring and an ejection rod, wherein the upper part of the lower die holder is connected to the lower die by a bolt; an inner diameter controller is arranged in the lower die; the steel ball seat, the backing board, the upper die holder are placed above the lower die and are connected in sequence; the steel ball is placed between the lower die and the steel ball seat; the ejection rod is arranged in the steel ball seat; and a push device is arranged at the upper end of the ejection rod. According to the invention, a returned material device and the steel ball seat are integrated, so that workpieces are reduced, matching surfaces are decreased accordingly, assembly error is lowered, and a gap between the inner diameter controller and an inner bore of the lower die is enlarged as the returned material is realized by using the ejection rod to push the holder out of the steel ball seat, thereby avoiding the generation of burrs.
Description
Technical field
The present invention relates to a kind of mode structure, be specifically related to the sizing die structure for retainer.
Background technology
The ribbon retainer production technology mainly is comprised of punch process operations such as cutting ring, shaping, shaping, punching.When trimming is the ribbon retainer punch process, retainer finished product geometry beyond the assurance derivet hole dimension, the main program of size are that the retainer semi-finished product that the ribbon retainer molding procedure processes are finished shaping semi-finished product processing process by trimming.
Ribbon retainer trimming crudy is mainly guaranteed by the trimming moulds of industrial equipment.Therefore the shaping mould quality is directly connected to the quality of ribbon retainer shaping.
Shaping mould complex structure, Mould Machining quality just are not easy to be guaranteed, and the assembly relation of mould easily make assembling after the mould accumulated error increase, can't guarantee the normal production of retainer trimming.Shaping adds man-hour, easily produce retainer I deceive, the revisal of nest position, planar portions are smooth, in the light one side of one side, the problem such as burr.
Summary of the invention
The present invention relates to structure simply for the sizing die structure of retainer, solved the problem that the retainer of producing easily produces burr.
The technical scheme that the present invention adopts for achieving the above object is:
Be used for the sizing die structure of retainer, comprise die shoe, die, steel ball, upper bolster, backing plate, steel ball seat, liftout spring, push-off pin; Described die shoe top screw connects die, is provided with the internal diameter controller in the described die, and the top of described die is laid steel ball seat, backing plate, upper bolster successively, and described steel ball seat, backing plate, upper bolster connect successively; Described steel ball is placed between die and the steel ball seat, and described push-off pin is arranged in the steel ball seat, and described push-off pin upper end is provided with thrust unit.The formed circular diameter of described steel ball seat and die is greater than the diameter of steel ball, and the diameter range of described steel ball is 10～50mm.
Described thrust unit is spring or pneumatic cylinder.
Also comprise centring ring and locating dowel, described centring ring is fixed on the internal diameter controller, and the top of described locating dowel is positioned at backing plate central authorities, and the bottom is positioned at the steel ball seat middle part, and extends steel ball seat.
Connect by 2 screw A between described steel ball seat and the backing plate.
Connect by screw B between described upper bolster and the backing plate.
The present invention compared with prior art has the following advantages and beneficial effect:
The present invention is integrated discharging device and steel ball seat, and workpiece reduces, and mating surface is corresponding minimizing also, rigging error reduces, and the material returned adopts push-off pin that retainer is released from steel ball seat, has strengthened the gap of internal diameter controller and die endoporus, can avoid the generation of burr.
Description of drawings
Fig. 1 is structure chart of the present invention;
The name that Reference numeral is corresponding is called: 1-die shoe, 2-die, 3-steel ball, 4-upper bolster, 5-backing plate, 6-steel ball seat, 7-thrust unit, 8-push-off pin, 9-internal diameter controller, 10-centring ring, 11-locating dowel, 12-screw A, 13-screw B.
