Description

Technical Field

[0001] The present application relates to the technical field of parts processing, and in particular to a deep-drawing parts bulging processing die clamping mechanism. Background Art

[0002] Deep drawing refers to a metal plastic processing method in which a metal sheet is punched into a part with a large depth on a press die. Deep drawing parts are generally processed using a bulging die. A bulging die is a die that obtains a convex-shaped part by causing local plastic deformation of the ingredients, thinning the material, and increasing the surface area.

[0003] The expansion processing die is the stamping part for deep drawing of parts. The processing die is mostly used by direct assembly on the machine tool. The stamping inner diameter of the stamping surface of the part usually needs to be determined before leaving the factory. For expansion punching of different depths, processing dies with different gradients and the same hole inner diameter are equipped. During conventional use, the workpiece needs to be transferred between multiple gradients to achieve punching of different depths. The same effect can also be achieved by replacing the processing die loaded on the machine tool. However, due to the complexity of the assembly process, one of the processing methods is currently used more often.

[0004] Since the thin wall produced by the expansion of the workpiece is prone to deformation during the demolding process during the transfer of the workpiece, the design of a clamping mechanism that can flexibly replace the processing mold has good prospects for improving product yield. A deep drawing part bulging processing mold clamping mechanism is proposed to solve the above-mentioned problems. Utility Model Content

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a deep-drawing part bulging processing die clamping mechanism, comprising two machine bases, guide rails located on the machine bases and deep-drawing dies connected to the guide rails, wherein the machine bases are provided with a driving structure for traction stamping and a clamping mechanism connected between the driving structure and the deep-drawing dies;

[0007] The clamping mechanism includes a hinge, a mounting tube fixedly connected to the outside of the hinge, and a connecting rod located in the mounting tube. The clamping mechanism also includes a clamping tube fixedly installed inside the mounting tube, the clamping tube is attached to the outer wall of the connecting rod, and the outside of the clamping tube is broken into multiple arc segments.

[0008] Furthermore, the guide rail and the base are fixedly connected via a bracket.

[0009] Furthermore, the driving structure includes a motor fixedly mounted on the outside of one of the machine bases, a cam block rotatably mounted on the insides of two of the machine bases, and a hinge rotatably connected to the two cam blocks.

[0010] Furthermore, the number of the cam blocks is two, and one of the cam blocks is fixedly connected to the power end of the motor.

[0011] Furthermore, a connecting ball is rotatably mounted on the end of the connecting rod, and the connecting ball is embedded in the sliding block.

[0012] Furthermore, a threaded rod is fixedly installed inside the mounting tube, and the connecting rod is threadably connected to the threaded rod.

[0013] Furthermore, an extrusion tube is threadedly mounted on the inner wall of the mounting tube, and a ramp block is fixedly mounted on the outer wall of the clamping tube, and the surface of the ramp block is inclined to the outer wall of the clamping tube.

[0014] Furthermore, the inner diameter of the extruded tube is smaller than the diameter of the ramp block, and an adjusting ring is fixedly mounted on one end of the extruded tube extending to the outside of the mounting tube.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] The deep-drawing part bulging processing die clamping mechanism is configured such that a connecting rod for connecting a slider can be rotated relative to a mounting tube to adjust its length.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] See also Figure 1-4 In this embodiment, a deep-drawing part bulging processing die clamping mechanism includes two machine bases 1, guide rails 2 located on the machine base 1, and a deep-drawing die connected to the guide rails 2, wherein the guide rails 2 and the machine base 1 are fixedly connected by a bracket 3, and the guide rails 2 and the machine tool foundation can also be directly connected and fixed to each other.

[0024] Preferably, the deep drawing die includes a slider 10 slidably connected to the guide rail 2 and an expansion die 11 fixedly mounted on the slider 10 .

[0025] In this embodiment, a driving structure for traction stamping and a clamping mechanism connected between the driving structure and the deep-drawing die are provided on the machine base 1, and the driving structure includes a motor 4 fixedly mounted on the outside of a machine base 1, a cam block 5 rotatably mounted on the inner sides of two machine bases 1, and a hinge 6 rotatably connected to the two cam blocks 5, wherein the number of the cam blocks 5 is two, and one cam block 5 is fixedly connected to the power end of the motor 4, and can be driven by the motor 4 to rotate.

[0026] It should be noted that the clamping mechanism includes a mounting tube 7 fixedly connected to the outside of the hinge 6, a connecting rod 8 located in the mounting tube 7, a connecting ball 9 is rotatably mounted on the end of the connecting rod 8, and the connecting ball 9 is embedded in the slider 10. The slider 10 can complete the connection between the connecting ball 9 and the connecting rod 8, so that the connecting rod 8 can freely deflect relative to the slider 10;

[0027] The clamping mechanism further comprises a clamping tube 12 fixedly mounted inside the mounting tube 7 . The clamping tube 12 is fitted to the outer wall of the connecting rod 8 , and the outer portion of the clamping tube 12 is broken into multiple arc segments.

[0028] Such a design enables the clamping tube 12 to be forced to contract the clamping link 8 when external stress is applied to the clamping tube 12 .

[0029] In this embodiment, a threaded rod 16 is fixedly installed inside the mounting tube 7, and the connecting rod 8 is threadedly connected to the threaded rod 16. By rotating the connecting rod 8, the connecting rod 8 can be moved relative to the threaded rod 16, thereby adjusting the length of the connecting rod 8 extending to the outside of the mounting tube 7.

[0030] In this embodiment, an extrusion tube 14 is threadedly mounted on the inner wall of the mounting tube 7 , and a ramp block 13 is fixedly mounted on the outer wall of the clamping tube 12 . The surface of the ramp block 13 is inclined to the outer wall of the clamping tube 12 .

[0031] In a specific implementation, since the inner diameter of the extrusion tube 14 is smaller than the diameter of the ramp block 13 , the extrusion tube 14 can exert an extrusion force on the ramp block 13 .

[0032] It should be noted that an adjustment ring 15 is fixedly mounted on one end of the extrusion tube 14 extending to the outside of the mounting tube 7 , and the extension length position of the extrusion tube 14 relative to the mounting tube 7 can be conveniently changed by rotating the adjustment ring 15 .

[0033] The working principle of the above embodiment is:

[0034] By assembling the machine base 1 and the guide rail 2 on the processing machine tool, the motor 4 can be driven to drive the cam block 5 on the power end to rotate, and the cam block 5 drives the hinge 6 to move up and down relative to the machine base 1 under the rotation, so as to complete the pulling of the installation pipe 7, and the connecting rod 8 drives the slide block 10 to slide and adjust along the expansion die 11 for stamping;

[0035] When it is necessary to adjust the extension length of the connecting rod 8, the connecting rod 8 is rotated so that the connecting rod 8 is threadedly engaged with the threaded rod 16 during rotation, thereby allowing the connecting rod 8 to be extended and adjusted relative to the threaded rod 16. After the adjustment is completed, the adjusting ring 15 connected to the end of the extrusion tube 14 is rotated. The adjusting ring 15 drives the extrusion tube 14 to rotate relative to the mounting tube 7 during rotation. The extrusion tube 14 is threadedly connected to the mounting tube 7 and moves along the inner wall of the mounting tube 7. The inner wall of the extrusion tube 14 is squeezed by contact with the ramp block 13 on the outer wall of the clamping tube 12, so that the clamping tube 12 can be squeezed by the extrusion tube 14, thereby limiting the rotation of the connecting rod 8 and achieving locking.
