Description
Technical field
The utility model relates to stamping technology field, particularly relates to a kind of R shape sheet spring bending die.
Background technology
Sheet spring is widely used in power contacts device, and sheet spring has various shape and structure because purposes is different, and as shown in Figure 4, be a kind of R shape sheet spring, raw material adopt bronze lath, are shaped by bending die bending machining.Common bending, processing is divided into two procedures, first raw material U-shaped bending die is bent to U-shaped part, with shaping bending die, U-shaped part is bent to final shape again, this method is because needing two minor bend moulds, two procedures separate operation, machining period is long, and production cost is high.
Utility model content
Problem to be solved in the utility model is, for the above-mentioned defect of prior art, provide a kind of minor bend mould that only needs can bend to R shape, machining period is short, the R shape sheet spring bending die that production cost is low.
The purpose of this utility model is achieved through the following technical solutions.R shape sheet spring bending die, comprise upper bolster, punch, die shoe, punch is fixedly connected on below upper bolster, described die shoe upper surface is fixedly connected with die socket, die socket upper side is provided with the first groove being through to trailing flank from die socket leading flank, rotating shaft is provided with in first groove, rotating shaft is provided with the second groove extended vertically, the face, rear and front end of rotating shaft is fixedly connected with respectively the upper end of spring, the lower end of spring is fixedly connected on die shoe, and the left and right sides of die socket upper side is respectively equipped with location structure.During work, be placed on by raw material on die socket, patrix is descending, and the first groove raw material compressed into by punch and to the second groove, rotating shaft rotates under the effect of punch, raw material is pressed into R shape product.The utility model, only needs a minor bend mould can complete the processing of product, shortens machining period, reduce production cost.
As preferably, the length of described rotating shaft is equal with the length of side before and after die socket, the front/rear end of rotating shaft is respectively equipped with baffle plate, baffle plate is fixedly connected on the front and back sides of die socket, the position that the height of baffle plate is connected with spring lower than rotating shaft front/rear end, baffle plate can prevent from altering outside rotating shaft, improves the quality of mould.
As preferably, the lower surface of described upper bolster is fixedly connected with middle plate, and the lower surface of middle plate is fixedly connected with lower plate, and punch is fixedly connected in lower plate.
As preferably, described location structure is location-plate, and location-plate is fixedly connected on the upper side of die socket.
As preferably, the upper surface of described upper bolster is fixedly connected with die shank.
The beneficial effects of the utility model are, only need a minor bend mould can bend to R shape sheet spring, machining period is short, and production cost is low, and structure is simple, easy to operate.

Structural representation when Fig. 1 is the separation of the utility model upper and lower mould.
Structural representation when Fig. 2 is the pressing of the utility model upper and lower mould.
Fig. 3 is the side view of counterdie.
Fig. 4 is the structural representation of R shape sheet spring.
Detailed description of the invention
Below the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
Embodiment, as shown in Fig. 1 to Fig. 3, R shape sheet spring bending die, be made up of patrix and counterdie, patrix is by die shank 1, upper bolster 2, middle plate 3, lower plate 4, composition such as punch 5 grade, die shank is fixedly connected on upper bolster upper surface, middle plate is fixedly connected on upper bolster lower surface, lower plate is fixedly connected on middle plate lower surface, upper bolster, middle plate, lower plate is fixed together by screw and straight pin, the upper end of punch is fixedly connected on lower plate by step, the lower end of punch is passed lower plate and vertically stretches out from its lower surface, the cross section of punch is rectangular, the longitudinal cross-section of punch lower end is R shape.Counterdie is by die shoe 10, die socket 7, rotating shaft 11, baffle plate 8, spring 9, composition such as location-plate 6 grade, die socket is fixedly connected on die shoe upper surface by screw, the basic configuration of die socket is cuboid, die socket upper side is provided with the first groove 71 being through to trailing flank from die socket leading flank, rotating shaft 11 is set in first groove, rotating shaft can be rotated in the first groove, rotating shaft is provided with the second groove 111 extended vertically, the length of rotating shaft is equal with the length of side before and after die socket, the front/rear end of rotating shaft is respectively equipped with baffle plate 8, baffle plate is fixedly connected on the front and back sides of die socket.The face, rear and front end of rotating shaft is fixedly connected with respectively the first steady pin 13, the position of the first steady pin is higher than the height of baffle plate, the upper end of spring 9 is fixedly connected on the first steady pin, the lower end of spring is fixedly connected on the second steady pin 14, second steady pin is fixedly connected on die shoe, and the left and right sides of die socket upper side is fixedly connected with location-plate 6 respectively.During work, raw material are placed on die socket, patrix is descending, and the first groove raw material compressed into by punch and to the second groove, rotating shaft rotates under the effect of punch, raw material are pressed into R shape sheet spring 12, spring is stretched, and patrix is up, and R shape sheet spring is along with up, rotating shaft gets back to original position under the force of a spring, R shape sheet spring can be taken off from punch.The utility model, only needs a minor bend mould can complete the processing of product, shortens machining period, reduce production cost.
The above is the utility model preferably detailed description of the invention, not limits practical range of the present utility model with this.The utility model can also have other embodiment, and only otherwise deviate from spirit of the present utility model, no matter in form what kind of conversion all drops within protection domain of the present utility model.
