Description

Technical Field

[0001] The utility model belongs to the technical field of part processing tooling, and more specifically, particularly relates to a swaging tooling for the end of a fork screw rod. Background Art

[0002] A fork screw rod refers to a rod with threads, and one or both ends thereof have flat or special-shaped heads, which can be used in cooperation with a fork. By rotating the screw rod, the fork can be pushed or pulled, thereby realizing the conversion of linear motion. It is commonly found in parts used in fields such as automobiles, machine tools, aerospace, and automation equipment.

[0003] For the end shaping of the fork screw rod, swaging and extrusion are required. However, the clamping tooling on the existing swaging press has poor stability. During the swaging process, the position of the workpiece is prone to deviation and is easily affected by external interference, resulting in low processing efficiency.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a swaging tooling for the end of a fork screw rod is provided, in order to achieve a more practical value purpose. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a swaging tooling for the end of a fork screw rod to solve the problems of poor stability of the clamping tooling on the swaging press, easy deviation of the workpiece position during the swaging process, easy interference from the outside, and low processing efficiency.

[0006] The purpose and effect of the swaging tooling for the end of a fork screw rod of the utility model are achieved by the following specific technical means:

[0007] A swaging tooling for the end of a fork screw rod includes a lower die body and an upper die body. The lower die body includes a support table and a support column integrally formed with the center of the support table. A connecting ring is arranged on the periphery of the support column. A placement hole is opened at the top of the support column. The upper die body is a hollow cylinder with a sealed top. A threaded groove is opened at the bottom of the inner wall of the upper die body. The threaded groove is in threaded engagement with the connecting ring. An accommodation hole corresponding to the placement hole is opened at the top of the upper die body.

[0008] Further, a positioning groove extends around the top of the placement hole.

[0009] Further, handles are arranged on the peripheries of both the lower die body and the upper die body.

[0010] Further, the handle is horizontally inserted through the upper die body or the lower die body and is in threaded connection with it.

[0011] Further, a backing plate is arranged on the inner top wall of the upper die body.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By placing the workpiece on the lower die body, inserting its stud into the placement hole, and screwing the upper die body with the lower die body, the end of the nut is urged against the inner wall of the upper die body. Then, the riveting head of the press can be rotated to squeeze the nut to complete the riveting. The fixation of the upper die body and the lower die body reduces the external interference on the workpiece, makes the tooling fixation structure more stable, and improves the processing efficiency.

[0023] Example:

[0024] As attached Figure 1 To Attachment Figure 4 As shown:

[0025] The utility model provides a riveting tool for the end of a shift fork screw rod, comprising a lower die body 1 and an upper die body 2.

[0026] like Figure 2 As shown, the lower mold body 1 includes a support platform 101 and a support column 102 integrally formed with the support platform 101 at the center. A connecting ring 103 is arranged around the support column 102. A placement hole 105 is opened on the top of the support column 102. The stud of the screw rod 4 can be inserted into the placement hole 105 to limit the position of the screw rod 4.

[0027] like Figure 3 and Figure 4 As shown, the upper mold body 2 is a hollow cylinder with a top seal, and a threaded groove 202 is provided at the bottom of the inner wall of the upper mold body 2, and the threaded groove 202 is threadedly engaged with the connecting ring 103. By buckling the upper mold body 2 on the support 102 of the lower mold body 1 and sliding downward until the upper mold body 2 contacts the connecting ring 103, the upper mold body 2 can be rotated continuously to continue to move downward, so that the upper mold body 2 can finally squeeze the screw 4 placed on the fixed support column 102, and a pad 203 is provided on the inner top wall of the upper mold body 2 to reduce the wear of the upper mold body 2 caused by long-term extrusion;

[0028] The top of the upper mold body 2 is provided with a receiving hole 201 corresponding to the placement hole 105, and the nut at the head of the screw rod 4 extends from the receiving hole 201 so that it can be docked with the rivet head on the press. In this embodiment, the top of the placement hole 105 extends to the surroundings to form a positioning groove 104 for matching the step below the end of the screw rod 4. The lower mold body 1 and the upper mold body 2 are both provided with handles 3. Figure 1 As shown, the handle 3 is transversely passed through the upper mold body 2 or the lower mold body 1 and is threadedly connected thereto, and can be removed at any time. The arrangement of the handle 3 facilitates the control of the lower mold body 1 and the rotation of the upper mold body 2.

[0029] The fixing of the screw rod 4 by the upper mold body 2 and the lower mold body 1 reduces external interference on the workpiece, makes the tooling fixing structure more stable, and improves the processing efficiency.

[0030] When using:

[0031] Place the lead screw 4 on the lower die body 1, insert the stud of the lead screw 4 into the placement hole 105, then screw the upper die body 2 onto the lower die body 1, causing the end of the nut to abut against the bottom wall of the upper die body 2, so that the end of the stud located in the nut is aligned with the receiving hole 201. Then, insert the riveting head on the press into the receiving hole 201, and rotate and extrude the end of the stud in the nut at high speed, causing the end of the nut to deform into a disc shape, thereby completing the riveting.

[0032] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better illustrate the principles of the present invention and its practical application, and to enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.
