Description

Technical Field

[0001] The utility model relates to the technical field of die processing and stamping, in particular to a stamping and clamping tool for automobile die processing. Background Art

[0002] A stamping die is a special process equipment used to process materials into parts during cold stamping. It is called a cold stamping die. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation, thereby obtaining the desired parts.

[0003] At present, molds have been widely used in the production process. Different molds will be used according to the different requirements of parts and components. In addition, different tables are required to clamp molds of different specifications and sizes according to actual production needs. The existing clamping equipment is for clamping molds of a single size and specification, which limits the use of stamping molds. Therefore, a stamping clamping tooling for automobile mold processing is proposed.

[0005] However, the above technical solution still has certain defects. During use, when the hydraulic rod pushes the upper mold to move downward, so that the upper mold and the lower mold are closed, the downward impact force of the upper mold is directly transmitted to the lower mold, which can easily cause damage to the mold and reduce the service life of the mold. For this reason, a stamping and clamping tooling for automobile mold processing is proposed. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0026] The following describes an embodiment of the utility model based on its overall structure.

[0027] A stamping and clamping tool for automobile mold processing, such as Figures 1 to 4As shown, it comprises a support mechanism 1, the outer wall of the support mechanism 1 is slidably connected with a clamping mechanism 2, and the top of the support mechanism 1 is fixedly connected with a hydraulic rod 3;

[0028] The support mechanism 1 includes a base 101, a bracket 107 is fixedly connected to the top of the base 101, a guide rod 102 is fixedly connected to the top of the base 101, the outer wall sliding sleeve of the guide rod 102 is provided with two groups of sliding sleeves 103, the tops of the two groups of sliding sleeves 103 are respectively hinged with a group of push rods 104, the tops of the push rods 104 are hinged to the bottom of the clamping mechanism 2, the side walls of the sliding sleeves 103 are fixedly connected to the damping assembly 106, the outer wall sleeve of the guide rod 102 is provided with a reset spring 105, one end of the reset spring 105 is fixedly connected to the outer wall of the guide rod 102, and the reset spring 1 05 is fixedly connected to the side wall of the sleeve 103, the damping assembly 106 includes a sleeve 1061, the sleeve 1061 is fixedly connected to the top of the base 101, the inner wall of the sleeve 1061 is slidably sleeved with a piston 1062, the side wall of the piston 1062 is fixedly connected with a group of push rods 1063 extending to the outside of the sleeve 1061, one end of the push rods 1063 located outside the sleeve 1061 is fixedly connected to the side wall of the sleeve 103, the side wall of the piston 1062 is provided with a through hole 1064 penetrating both sides of the piston 1062, and the inner wall of the sleeve 1061 is filled with damping oil 1065.

[0029] The thrust when the upper mold moves downward and closes the mold with the lower mold pushes the clamping table 201 to slide downward, so that the clamping table 201 pushes the two sets of sliding sleeves 103 to slide on the outer wall of the guide rod 102 and move away from each other through the two sets of push rods 104, thereby compressing the reset spring 105. At the same time, the sliding sleeve 103 pushes the push rod 1063, so that the push rod 1063 pushes the piston 1062 to slide inside the sleeve 1061. During the sliding process of the piston 1062, the damping oil 1065 inside the sleeve 1061 is pushed by the piston 1062, so that one side of the piston 1062 flows to the other side of the piston 1062 through the through hole 1064. Since the diameter of the through hole 1064 is small and the resistance The viscosity of nylon oil 1065 is relatively high, so that the piston 1062 is subjected to greater damping during the sliding process, so that the impact force generated by the mold closing is consumed. As the hydraulic rod 3 continues to push the upper mold downward, when the clamping table 201 is blocked by the base 101 and cannot slide down, at this time, under the push of the hydraulic rod 3, the upper mold and the lower mold complete the stamping process, and then the upper mold is reset under the drive of the hydraulic rod 3. At this time, the reset spring 105 pushes the sleeve 103 to reset, so that the sleeve 103 drives the push rod 1063 to reset, thereby resetting the piston 1062. During the reset process of the sleeve 103, the sleeve 103 pushes the clamping table 201 to reset through the push rod 104.

[0030] Please refer to Figure 1 and Figure 3 The clamping mechanism 2 includes a clamping platform 201, which is slidably connected to the outer wall of the bracket 107, and the bottom end of the clamping platform 201 is hinged to the top of the two groups of top rods 104. The inner wall of the clamping platform 201 is rotatably connected to a turntable 202, and the side walls of the turntable 202 are connected with multiple groups of connecting rods 203, and the ends of the multiple groups of connecting rods 203 are respectively connected with a group of chucks 204, and the multiple groups of chucks 204 are slidably connected to the top of the clamping platform 201. The side walls of the chucks 204 are provided with multiple groups of anti-slip grooves, and a worm gear 205 is fixedly sleeved at the bottom end of the turntable 202. The inner wall of the clamping platform 201 is rotatably connected to a worm 206 extending to the outside of the clamping platform 201, and the worm 206 is meshed with the worm gear 205. One end of the worm 206 located outside the clamping platform 201 is fixedly connected to a handle, and the outer cover of the handle is provided with a rubber sleeve.

[0031] The lower half of the mold is placed on the clamping table 201 so that the mold is located in the middle of the multiple sets of chucks 204. The worm 206 is then rotated so that the worm 206 drives the worm wheel 205 to rotate. The worm wheel 205 drives the turntable 202 to rotate during the rotation. The rotation of the turntable 202 pulls the multiple sets of chucks 204 closer to each other through the connecting rod 203, so that the multiple sets of chucks 204 are tightly attached to the outer wall of the mold, thereby clamping and fixing the mold. The worm 206 is rotated in the opposite direction so that the worm wheel 205 rotates in the opposite direction. At this time, the turntable 202 rotates in the opposite direction, so that the turntable 202 pushes the multiple sets of chucks 204 away from each other through the connecting rod 203, so that the mold is released.

[0032] When in use, the upper mold pushes the lower mold downward while the upper mold is closing, causing the clamping table 201 to move downward, and then the downward impact force is buffered by resetting the spring and damping assembly 106, so that the mold is not easily damaged during the production process, thereby increasing the service life of the mold.
