Detailed Description

In the embodiment, as shown in fig. 1 to 6, a clutch disc spring one-die two-die mold structure is used for molding a first clutch disc spring a with a large diameter and a second clutch disc spring B with a small diameter, so that continuous processing of the two clutch disc springs is realized. The specific die structure comprises an upper die plate 1 and a lower die plate 2, a male die base plate 3 and a male die fixing plate 4 are sequentially overlapped on the upper die plate 1, a second clutch disc spring inner hole forming male die 5 is sequentially arranged on the male die fixing plate 4 along the material belt conveying direction, an externally-tangent male die 6 is used for forming the local appearances of a front first clutch disc spring and a rear first clutch disc spring, a second clutch disc spring blanking male die 7 is used for realizing blanking of the second clutch disc spring, a first clutch disc spring inner hole forming male die 8 is used for forming a first clutch disc spring inner hole, and a cutting forming male die 9 is used for cutting off the outer contours of the front first clutch disc spring and the rear first clutch disc spring and forming a cut-off part.

The lower die plate 2 is sequentially overlapped with a female die base plate 10 and a punching female die 11, the punching female die 11 is provided with a forming hole 20 matched with the male die, and a blanking hole 21 is formed in the corresponding position of the female die base plate 10.

In order to prevent the material strap from moving upwards along with the male die, a material pushing plate 12 capable of moving up and down is arranged below the male die fixing plate 4, an elastic component 13 is arranged between the material pushing plate 12 and the male die fixing plate 4, the elastic component 13 can be elastic rubber or a spring, and the material pushing plate 12 and the male die fixing plate 4 are uniformly distributed on the elastic component 13, so that when the material pushing plate 12 is pressed, the stress is uniform everywhere, and the material pushing plate 12 is guaranteed to move along the opening and closing direction of the die.

In order to ensure the matching precision of the upper die and the lower die, a main guide post 14 is arranged on the lower die plate 2, a main guide sleeve 15 matched with the main guide post 14 is arranged on the upper die plate 1, a group of auxiliary guide posts 16 are arranged on the punch fixing plate 4, and a group of guide holes 17 matched with the auxiliary guide posts 16 are arranged on the punching female die 11.

In order to ensure the advancing direction of the material belt, guide rails 18 for limiting the material belt to swing are arranged on two sides of the punching female die 11, and a flange 181 which is pressed above the material belt and prevents the material belt from being separated from the two guide rails 18 is arranged on each guide rail 18. In order to control the feeding amount of the material belt each time, a stop block 19 for controlling the feeding amount of the material belt is fixedly arranged at the tail end of the punching female die 11. During punching, the material belt can be automatically fed into the die through the automatic feeding machine, so that automatic processing is realized.

The structure formed by the die on the material belt through one-time stamping is shown in fig. 6, an arrow in the figure is the advancing direction of the material belt, and the synchronous forming of the first clutch belleville spring a and the second clutch belleville spring B can be completed simultaneously. Stamping the material belts in the same area, wherein 4 processes can be performed according to the feeding amount of the material belts each time, firstly, the material belts complete the punch forming of the inner hole of the second clutch belleville spring under the action of a second clutch belleville spring inner hole forming male die 5 at a first station, and complete the punch forming of the appearance of the front side part of the first clutch belleville spring under the action of a first clutch belleville spring local appearance circumscribed male die 6; and then the material belt advances one station to reach a second forming station, at the moment, the second clutch belleville spring is processed and formed under the action of a blanking male die 7 of the second clutch belleville spring, and meanwhile, the external cutting male die 6 of the local shape of the first clutch belleville spring is used for stamping and forming the shape of the rear side part of the first clutch belleville spring. Then the material belt advances a station again, at the moment, the part of the material belt completes the forming of the inner hole of the first clutch belleville spring under the action of the inner hole forming male die 8 of the first clutch belleville spring; and finally, the material belt enters the last station, the first clutch belleville springs are disconnected from the material belt under the action of the cutting and forming male die 9, and the shape of the connecting position of the front first clutch belleville spring and the shape of the connecting position of the rear first clutch belleville spring are formed. The disconnected first clutch belleville spring directly falls down through a gap between the punching female die 11 and the stop block 19, so that the material belt can be continuously pushed forwards, and the two clutch belleville springs are circularly pushed to finish continuous processing.
