Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die for a disc spring to prevent deviation. Background Art

[0002] A stamping die is a kind of process equipment used for stamping processing. It completes the processing of materials through the relative movement of the upper and lower dies to produce the required parts or semi-finished products.

[0003] The utility model patent with the authorized patent number of CN218015145U discloses a stamping die for a disc spring to prevent deviation, including a set bottom plate, and telescopic rods are symmetrically arranged at the top of the bottom plate, and a die body is fixed at the top of the telescopic rods, and a disc spring body is connected between the bottom of the die body and the bottom of the bottom plate, and the disc spring body is sleeved outside the telescopic rods; a top plate is connected to the top of the bottom plate, and a hydraulic driving member is arranged in the middle of the top plate, and a punch is installed at the bottom of the hydraulic driving member; further comprising: a die cavity is formed in the middle of the top surface of the die body, fixing plates are symmetrically arranged on the left and right sides of the top of the die body, movable toothed plates are connected to the inner side walls of the fixing plates, and pressing plates are connected to the tops of the fixing plates.

[0004] It is found in the use of the above patent that: the above patent uses the top pressing plate and the lateral movable toothed plate to clamp and fix the components in multiple directions during the stamping process to prevent the components in the die from deviating during the stamping process. However, when the movable toothed plate moves and clamps, it will drive the gear inside it to rotate, and then the gear drives the threaded rod to drive the upper pressing plate to move. Therefore, when the lateral movable toothed plate moves, it will be associated with driving the pressing plate to move. Therefore, when the movable toothed plate clamps the component to be stamped, the aspect ratio of the stamping component must meet certain requirements, and the upper clamping plate can clamp its top. To sum up, when clamping the component in the above patent, the aspect ratio of the component must meet the requirements to be clamped, and the applicability is not strong, and it is difficult to be applicable to the stamping processing work of multi-specification components. For this reason, we propose a stamping die for a disc spring to prevent deviation to solve the above technical defects. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0024] Refer toFigures 1-4 , please refer to Figures 1-4 , where Figure 1 is a schematic three-dimensional structure diagram of a butterfly spring stamping die for preventing offset proposed by the present utility model Figure 1 ; Figure 2 is a schematic three-dimensional structure diagram of a butterfly spring stamping die for preventing offset proposed by the present utility model Figure 2 ; Figure 3 is a schematic three-dimensional structure diagram of a butterfly spring stamping die for preventing offset proposed by the present utility model Figure 3 ; Figure 4 is a schematic internal sectional structure diagram of an anti-offset mechanism of a butterfly spring stamping die for preventing offset proposed by the present utility model. A butterfly spring stamping die for preventing offset includes: a stamping table 1, a stamping die 2 is arranged directly above the stamping table 1, a butterfly spring 3 is installed between the stamping die 2 and the stamping table 1, a cylinder 5 is installed on the stamping die 2, a sliding box groove 6 is fixedly installed on the output end of the cylinder 5, and an anti-offset mechanism 7 is arranged on the sliding box groove 6.

[0025] In this mode, the anti-offset mechanism 7 includes a sliding block 71, an upper support plate 73 is fixedly installed on the top of the sliding block 71, an electric telescopic rod 75 is installed on the upper support plate 73, the output end extends to the lower side of the upper support plate 73, and an upper clamping plate 76 is fixedly installed on the output end of the electric telescopic rod 75. A second chute 711 is arranged inside the sliding box groove 6, a forward slider 712 is slidably installed inside the second chute 711, a connecting rod 713 is hinged between the forward slider 712 and the inner side of the sliding block 71, and a return spring 714 is connected between the forward slider 712 and the second chute 711.

[0026] Through the setting in the above manner, when the sliding block 71 clamps the side of the component to be processed, under the reverse action of the clamping force, the sliding block 71 will be pushed to slide inwardly in the sliding box groove 6, and it drives the forward slider 712 to slide inside the second chute 711 through the connecting rod 713 hinged inside. When the forward slider 712 slides inside, the forward slider 712 will be subjected to the return spring force of the return spring 714, so that the sliding block 71 has an elastic buffer zone when retracting, and further makes the sliding block 71 have an elastic clamping buffer interval when clamping the component.

[0027] In this mode, the butterfly springs 3 are arranged at the four corners of the stamping table 1. An expansion rod 31 is arranged inside the butterfly springs 3. The outer wall of the expansion rod 31 is in sliding contact with the butterfly springs 3. The upper and lower ends of the expansion rod 31 are respectively connected to the stamping table 1 and the stamping die 2. It should be noted here that a damping washer is provided between the outer wall of the butterfly spring 3 and the expansion rod 31, so that the butterfly spring 3 has a damping shock absorption effect when restoring deformation. This technology is an existing conventional technical means and will not be elaborated here.

[0028] With the above - mentioned setting, the telescopic rod 31 arranged inside the disc spring 3 provides a vertical guiding function for the deformation direction of the disc spring 3, and further provides a vertical guiding function for the stamping die 2.

[0029] In this method, a control switch 4 is fixedly installed on the stamping die 2. The control switch 4 is electrically connected to the air cylinder 5 and the electric telescopic rod 75 respectively. A stroke control valve is arranged on the air cylinder 5.

[0030] With the above - mentioned setting, the stroke control valve arranged on the air cylinder 5 enables the stroke of the air cylinder 5 to be controlled by the control switch 4, so that the air cylinder 5 can drive the sliding box groove 6 to slide different distances, enabling it to clamp components of different widths.

[0031] In this method, the upper clamping plate 76 is an L - shaped folding plate, and inclined ribs 74 are evenly arranged on the inner side of the upper clamping plate 76.

[0032] With the above - mentioned setting, the setting of the inclined ribs 74 strengthens the stiffness at the folding corner of the upper clamping plate 76.

[0033] In this method, a lateral cushion plate 72 is arranged on the outer side of the sliding block 71, and an upper cushion plate 77 is arranged at the bottom of the upper clamping plate 76. Both the lateral cushion plate 72 and the upper cushion plate 77 are anti - slip pads.

[0034] With the above - mentioned setting, the settings of the lateral cushion plate 72 and the upper cushion plate 77 can improve the clamping friction force and the clamping stability when clamping the component.

[0035] In this method, first chutes 79 are opened on the upper and lower sides inside the sliding box groove 6. Lateral sliding blocks 78 are fixedly installed on the upper and lower sides of the sliding block 71. A damping gasket 710 is installed inside the first chute 79, and the lateral sliding blocks 78 are in sliding contact with the damping gasket 710.

[0036] With the above - mentioned setting, when the sliding block 71 slides relative to the sliding box groove 6, the sliding block 71 will drive the lateral sliding blocks 78 on the side to slide relative to the damping gasket 710, preventing the sliding block 71 from repeatedly sliding and vibrating inside the sliding box groove 6 due to the resilience of the return spring 714 when the sliding block 71 releases the clamping, and reducing frictional losses.

[0037] In this method, the cleaning mechanism includes a folding rod 8. A groove tooth 9 is provided on the upper side of the folding rod 8, and the folding rod 8 is fixedly installed on the side of the sliding box groove 6. A gear 10 is meshed above the groove tooth 9. A rotating shaft 11 is fixedly installed at the rear end of the gear 10. A fan blade 12 is installed on the side wall of the rotating shaft 11. A rear support is rotatably connected behind the rotating shaft 11, and the rear support is fixedly installed on the stamping die 2. Here, it should be noted that the gear 10 is a small-diameter gear. When the folding rod 8 moves along with the sliding box groove 6, the meshing drive of the groove tooth 9 on the folding rod 8 can drive the gear 10 to rotate multiple circles. At the same time, the sliding box groove 6 is pushed by the air cylinder 5, and its speed is relatively fast. When clamping the components on the stamping die 2, the gear 10 on the side can be quickly rotated multiple circles, and then the fan blade 12 is quickly rotated, which plays a certain role in cleaning the surface of the components on the stamping die 2.

[0038] Through the above setting, when the sliding box groove 6 slides driven by the air cylinder 5, it can drive the folding rod 8 to move left and right on the stamping die 2, so that the groove tooth 9 on the folding rod 8 meshes with the gear 10, driving the rotating shaft 11 to rotate by the gear 10, and then the fan blade 12 on the rotating shaft 11 rotates along with the rotating shaft 11, generating a blowing effect and playing a certain role in cleaning the surface of the components on the stamping die 2.

[0039] The working principle of a butterfly spring stamping die for preventing deviation provided by the present utility model is as follows:

[0040] During use, the component to be processed is placed on the stamping die 2. The air cylinders 5 on both sides are started. When the air cylinders 5 are started, their output ends drive the sliding box groove 6 to slide towards the middle position of the stamping die 2 to clamp the side of the component. After the side clamping is completed, the electric telescopic rod 75 on the upper support plate 73 is started to extend, and the output end of the electric telescopic rod 75 drives the upper clamping plate 76 at the bottom to move downward, and then the upper side of the component is clamped. The setting of the lateral cushion plate 72 on the side of the sliding block and the upper cushion plate 77 at the bottom of the upper clamping plate 76 can improve the clamping friction and the clamping stability when clamping the component, prevent the component from shifting during stamping processing, improve the quality of stamping products. At the same time, when the sliding box groove 6 slides driven by the air cylinder 5, it can drive the folding rod 8 to move left and right on the stamping die 2, so that the groove tooth 9 on the folding rod 8 meshes with the gear 10, and the fan blade 12 on the rotating shaft 11 is driven by the gear 10 to rotate along with the rotating shaft 11, generating a blowing effect and playing a certain role in cleaning the surface of the components on the stamping die 2.

[0041] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
