Detailed Implementation

[0025] The present invention will now be described in detail with reference to the accompanying drawings.

[0026] As attached Figure 1 and attached Figure 2As shown, a semi-automatic circular chain forming mold according to an embodiment of this utility model includes a base plate 5, a lower left mold base 7, a lower right mold base 15, a left adjustment structure, a right adjustment structure, a left limiting structure 10, a right limiting structure 12, and an upper mold core 3. The base plate 5 has left and right sliding grooves. The lower left mold base 7 and the lower right mold base 15 are both slidably disposed in the sliding grooves. The left adjustment structure is connected to the left side of the lower left mold base 7, and the right adjustment structure is connected to the right side of the lower right mold base 15. The left limiting structure 10 is disposed on the left adjustment structure. Structurally, the right limiting structure 12 is set on the right adjusting structure, the left limiting structure 10 is used to limit the left end of the metal rod to be processed placed on the lower left mold base 7 and the lower right mold base 15, the right limiting structure 12 can adjust the right end of the metal rod to be processed, the left adjusting structure and the right adjusting structure are used to adjust the distance between the lower left mold base 7 and the lower right mold base 15, and the position of the distance relative to the metal rod to be processed, and the upper mold core 3 is used to press the metal rod to be processed between the lower left mold base 7 and the lower right mold base 15.

[0027] This utility model, through the coordinated arrangement of a base plate 5, a lower left mold base 7, a lower right mold base 15, a left adjustment structure, a right adjustment structure, a left limiting structure 10, and a right limiting structure 12, allows for the use of either the left or right adjustment structure as needed. This drives the lower left mold base 7 and the lower right mold base 15 to move along the slide groove according to different sizes or required dimensions of the metal rod to be processed, thereby changing the spacing between them to meet the size requirements of the metal rod. Simultaneously, by utilizing the left limiting structure 10 connected to the left adjustment structure and the right limiting structure 12 connected to the right adjustment structure, when adjusting the lower left mold base 7 and the lower right mold base 15, the left limiting structure 10 and the right limiting structure 12 can restrict the metal rod to remain relatively stationary. Therefore, after adjustment, the joint position or size of the formed circular chain can be changed as needed.

[0028] In this design, various specifications of chains, such as titanium alloy chains, can be manufactured as needed by replacing the upper mold core 3 and adjusting the lower left mold base 7 and lower right mold base 15. This improves the chain forming efficiency and stability. The upper mold core 3 has a circular arc groove to reduce indentation on the inner side of the metal rod to be processed, and a flat head for easy demolding. This device has a simple structure, requires only one person to operate, and is low in cost and highly efficient.

[0029] In another specific embodiment based on the above, the left adjustment structure includes a left adjustment seat 4 and a left adjustment screw 9. The left adjustment seat 4 is fixed to the left side of the base plate 5. The left adjustment seat 4 is provided with a left threaded hole that passes through from left to right. The left adjustment screw 9 is threaded into the left threaded hole and passes through to be rotatably connected to the left side wall of the lower left mold base 7 located on the right side of the left adjustment seat 4. In this way, the position of the lower left mold base 7 can be driven and adjusted as needed by rotating the left adjustment screw 9.

[0030] In another specific embodiment, the right adjustment structure includes a right adjustment seat 13 and a right adjustment screw 14. The right adjustment seat 13 is fixed to the right side of the base plate 5. The right adjustment seat 13 has a right threaded hole that extends through both sides. The right adjustment screw 14 is threaded into the right threaded hole and extends through to be rotatably connected to the right side wall of the lower right mold base 15 located on the left side of the right adjustment seat 13. Thus, the position of the lower right mold base 15 can be driven and adjusted as needed by rotating the right adjustment screw 14.

[0031] In the above embodiments, in specific embodiments of the left and right adjustment structures, the left adjustment screw 9 can be rotatably connected to the left side wall of the lower left mold base 7 via a bearing, and the right adjustment screw 14 can be rotatably connected to the right side wall of the lower right mold base 15 via a bearing; the left adjustment seat 4 and the right adjustment seat 13 can be bolted to the base plate 5.

The two lower dies 8 are rotatably connected to the upper ends of the left lower die base 7 and the right lower die base 15 on adjacent sides via pins. The rotatable lower dies 8 facilitate the forming of the metal rod to be processed in conjunction with the upper die core 3. In this embodiment, the sidewall of the lower die 8 is provided with a groove to assist in the forming of the metal rod. The maximum distance between the grooves of the two opposing lower dies 8 is not less than the minimum distance between the left lower die base 7 and the right lower die base 15. The lower dies 8 can be mounted on the left lower die base 7 and the right lower die base 15 via pins 2 and can roll with the metal rod to be processed. In this embodiment, the upper die core 3 and the lower dies 8 can be replaced individually as needed to adjust the corresponding spacing and change the specifications of the circular chain.

[0033] In another specific embodiment, the left limiting structure 10 includes an extension rod and a stop block. One end of the extension rod is fixed to the left adjusting structure by a first adjusting bolt, and the other end of the extension rod is connected to the stop block.

[0034] In a further specific embodiment, the end of the extension rod near the left adjustment structure has a strip-shaped adjustment through hole in the left-right direction. The first adjustment bolt passes through the adjustment through hole to fix the extension rod to the left adjustment structure. The first adjustment bolt can move left and right in the strip-shaped adjustment through hole. In this way, the relative position of the extension rod and the first adjustment bolt can be adjusted as needed through the strip-shaped adjustment through hole, thereby realizing the adjustment of the position of the abutment block.

[0035] In another specific embodiment, the right limiting structure 12 includes a mounting base and a second adjusting bolt. The mounting base is fixed to the right adjusting structure, and a threaded hole is provided on the mounting base.

[0041] To complete the forming of a titanium alloy circular link chain, the following steps are required: First, adjust the two lower dies 8 to the desired size and specifications of the circular link chain. Then, place the titanium alloy rod on the two lower dies 8, with the right end of the rod against the upper right limiting structure 12. Next, the upper die holder 11 drives the upper die core 3 to press down, completing the first step. Then, place the semi-circular end of the completed titanium alloy circular link chain against the upper left limiting structure 10. Finally, the upper die holder 11 drives the upper die core 3 to press down, completing the forming of the titanium alloy circular link chain. In this design, the right limiting structure 12 and the left limiting structure 10 can be used for positioning during the two pressing processes, facilitating quick and easy manufacturing of the circular link chain according to the settings. Adjusting the position of the right limiting structure 12 or the left limiting structure 10 allows for adjustment of the joint position or size of the circular link chain as needed.
