Abstract
The invention relates to an automatic ejection bending die and belong to the field of stamping dies. The automatic ejection bending die comprises a male die, a positioning plate, a formed part, a female die, a base late, a top plate, rubber, a support plate, a stud, and two nuts. An ejector plate, the rubber and the support plate are integrated in the bending die through the stud and the nuts. The ejector plate is inverted T shape. The lower end of the ejector plate is provided with a threaded hole. The rubber is cylindrically shaped when not stressed, and is drum shaped when stressed. One connecting end of the stud and one connecting end of each nut are provided with planes allowing a monkey wrench to be conveniently used. The positioning plate is connected with the female die through a screw. The positioning plate is rectangular. The middle of one end of the positioning plate is provided with a gap used for holding and positioning a steel plate. During mounting, one end of the gap is open to the center of the die, and the base plate is connected with the female die through a screw. The automatic ejection bending die is simple in structure, easy to manufacture and convenient to use, and allows the formed part on the bending die of a stamping machine to be well ejected out.
Description
Technical field
The present invention relates to a kind of automatic ejection bending die, belong to diel field, be mainly used in sheet metal bending forming and eject.
Background technology
When bending die is worked on hydraulic press, drip molding is stayed counterdie push rod in the lower push rod drive bending die of forcing press and is ejected; When bending die is worked on stamping machine, drip molding wants the smooth demoulding can adopt inverted structure to utilize knockout rod to provide power to eject.High with the relative stamping machine price of tonnage hydraulic press, mould adopts inverted structure can increase Design of Dies difficulty and cost.In order to use shaping bending die eject smoothly formation of parts on stamping machine, invent in practice a kind of automatic ejection bending die, this mould structure is simple, easily manufactured, cost is low.
Summary of the invention
In order better to realize bending die formation of parts, on stamping machine, eject smoothly, reduce Design of Dies and manufacturing cost, easy to operate, the invention provides a kind of simple in structure, be easy to manufacture, the automatic ejection mould of handiness.
Technical scheme of the present invention is: a kind of automatic ejection bending die, comprises punch, location-plate, formation of parts, die, backing plate, top board, rubber, gripper shoe, studs, nut.In described bending die, top board, rubber, gripper shoe connect and are combined into one with studs and double nut, and top board is anti-T shape, in top board lower end, is processed with screwed hole; Rubber is cylindrical when not being stressed, and after being stressed, is cydariform; Studs is connected use one end with nut is processed with the plane of being convenient to monkey wrench use.In described bending die, location-plate is connected with die by screw, and it is rectangular-shaped that location-plate is, and jagged for placing steel plate one end in the middle of one end, during installation, jagged one end is towards mold center, and backing plate is connected with die by screw.
During use, punch on stamping machine is pressed into die by the steel plate of having good positioning, top board, rubber are along with moving downward together, the segment distance punch stop motion of moving starts upwards return movement, rubber moves upward because the flexible potential energy of pressurized starts to drive top board, and top board ejects formation of parts thereupon from die.
Automatic ejection design of bending die described in the present invention is simple, is easy to manufacture, easy to use, realizes preferably ejecting of bending die formation of parts on stamping machine.
Accompanying drawing explanation
Figure is automatic ejection design of bending die schematic diagram of the present invention.
The specific embodiment
Referring to accompanying drawing, the invention provides a kind of automatic ejection bending die, comprise punch 1, location-plate 2, formation of parts 3, top board 4, rubber 5, die 6, backing plate 7, nut 8, gripper shoe 9, studs 10.
In described automatic ejection bending die, by monkey wrench, twist studs 10 and with plane one end, studs 10 is screwed in the screwed hole of top board 4, rubber 5, gripper shoe 9 are contained on studs 10 fastening with double nut 8 in turn.
In described automatic ejection bending die, location-plate 2 is by screw fastening on die 6, and backing plate 7 is connected with die 6 by screw, and location-plate 6 is rectangular-shaped, and one end is jagged for fixing steel plate use, and during installation, jagged one end is towards mold center.
In described automatic ejection bending die, punch 1 is pressed into die 6 to motion by the steel plate of having good positioning and is shaped as formation of parts 3, punch 1 moves downward and forces top board 4 to move downward together with rubber 5, the segment distance that moves stops, and under the elasticity of rubber 5 is recovered, drives top board 4 to move upward forming part 3 automatic ejection from die 6.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described.Although the present invention is had been described in detail with reference to embodiment, those of ordinary skill in the art is to be understood that, technical scheme of the present invention is modified or is equal to replacement, do not depart from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
