[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] To address the technical problems of low production efficiency and unstable product quality caused by manually bending and forming clamps, this utility model provides a clamp bending mold tooling that can quickly process and form clamps, and produce clamps of stable and reliable quality.

[0020] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a clamp bending mold tooling in one embodiment of the present invention. The clamp bending mold tooling includes: a base 1, a mandrel 2, a fixing device 3, and a bending device 4.

[0021] The base 1 is placed on the machining table and has threaded holes or pin holes for fixing on the machining table.

[0022] The mandrel 2 is mounted on the base 1, and the fixing device 3 is mounted on the base 1 and located on one side of the mandrel 2. The fixing device 3 cooperates with the mandrel to clamp and fix the sheet metal. The bending device 4 is rotatably connected to the mandrel 2. During the rotation, the bending device 4 contacts the sheet metal and can push the sheet metal to bend around the mandrel 2 into a clamp.

[0023] In some embodiments, the mandrel 2 includes an inner core 21 and an outer body 22. The lower end of the inner core 21 is fixedly connected to the base 1, and the outer body 22 is fixedly sleeved on the inner core 21. The outer body 22 is cylindrical. The sheet metal is bent around the outer body 22 to form a clamp.

[0024] The inner core 21 is detachably connected to the base 1 and / or the inner core 21 is detachably connected to the outer body 22. By adopting the detachable connection method, the outer body 22 of different sizes can be replaced, thereby processing clamps of different sizes.

[0025] In some embodiments, the base 1 has a threaded hole, and the lower end of the inner core 21 has an external thread, which are connected together. Depending on the size of the clamp, a suitable mandrel 2 is selected and installed onto the base 1. In these embodiments, the entire mandrel 2 needs to be replaced.

[0026] In other embodiments, the outer body 22 has a threaded hole coaxial with the outer body 22, and the upper part of the inner core 21 has a corresponding external thread. Depending on the size of the clamp, a suitable outer body 22 is selected and installed onto the inner core 21. In these embodiments, only the outer body 22 needs to be replaced.

[0027] In other embodiments, in addition to threaded connections, other connection methods can be used, such as keyed connections, as long as they can achieve a secure and detachable connection.

[0028] In some embodiments, the lower surface of the outer body 22 is spaced apart from the upper surface of the base 1, and the bending device 4 is rotatably connected to the inner core 21 between the outer body 22 and the base 1.

[0029] In some embodiments, the fixing device 3 includes a fixing block 31 and a fixing plate 32. The fixing block 31 is fixed on the base 1 and located on one side of the mandrel 2. The fixing plate 32 is connected to the fixing block 31. One end of the fixing plate 32 forms a fixing gap with the outer side of the mandrel 2 for clamping and fixing the plate material.

[0030] In some embodiments, the fixing plate 32 and the fixing block 31 can be fixedly slidably connected to adjust the width of the fixing gap to accommodate different mandrels 2 and plates of different thicknesses.

[0031] In some embodiments, the fixing plate 32 has a through groove, the fixing block 31 has a mounting hole, and the fixing device 3 further includes a fixing member 33. The fixing member 33 passes through the channel and is detachably connected to the mounting hole. The fixing member 33 can cooperate with the fixing block 31 to clamp the fixing plate 32. The fixing member 33 can also loosen the fixing plate 32, so that the fixing plate 32 can slide through the through groove and the fixing member 33 to adjust the position of the fixing plate 32. After adjustment, the fixing member 33 is used to fix the fixing plate 32.

[0032] In some embodiments, a threaded connection can also be used, where the mounting hole has an internal thread and one end of the fixing member 33 has a corresponding external thread, and the fixing member 33 is screwed into the mounting hole to clamp the fixing plate 32. In other embodiments, other connection methods, such as magnetic attraction, can also be used, as long as the above-mentioned technical effects can be achieved.

[0033] In some embodiments, the bending device 4 includes a base plate 41 and a bending block 42. The base plate 41 is rotatably connected to the inner core 21, i.e., located between the base 1 and the outer body 22. The bending block 42 is disposed on the base plate 41 and located on one side of the outer body 22. Rotation of the base plate 41 around the inner core 21 can drive the bending block 42 to rotate. During the rotation, the bending block 42 contacts the sheet metal and pushes the sheet metal to bend and shape around the outer body 22.

[0034] In some embodiments, to accommodate different mandrels and process clamps of different sizes, the bending block 42 needs to be able to move radially relative to the base plate 41. Therefore, the base plate 41 has an inverted stepped groove 411 arranged radially along the mandrel 2. The larger opening of the inverted stepped groove 411 is located on the lower surface of the base plate 41, and the smaller opening is located on the upper surface of the base plate 41. The bending block 42 includes a forming element 421 and a connecting bolt 422. The forming element 421 has a threaded hole at its lower end and is disposed on the base plate 41 and located on one side of the outer body 22. The connecting bolt 422 is slidably embedded in the stepped groove 411 and extends from the upper opening of the stepped groove 411 to connect with the threaded hole.

[0035] The bending block 42 can slide along the stepped through groove 411 to adjust the distance between the bending block 42 and the mandrel 2. After the bending block 42 is moved to the desired position, the connecting bolt 422 and the forming part 421 are clamped in the stepped part of the stepped through groove 411 by tightening the connecting bolt 422, so that the bending block 42 is fixed on the base plate 41.

[0036] In some embodiments, the bending device 4 further includes a handle 43 connected to the base plate 41, enabling the operator to rotate the base plate 41 more effectively.

[0037] To better understand this utility model, the following is combined with... Figure 1The technical solution of this utility model is described in detail as follows: A suitable mandrel 2 is selected according to the size of the clamp, and the bending block 42 is adjusted to a suitable position on the base plate 41. Then, the mandrel 2 and the bending device 4 are installed on the base 1. The position of the fixing plate 32 is adjusted by the fixing member 33 so that the fixing plate 32 and the mandrel 2 cooperate to clamp the sheet material. Before the bending device 4 rotates, the fixing block 31 and the bending block 42 are located within the acute angle area clamped by the fixing plate 32 and the sheet material. The bending device 4 is pushed according to the direction of rotation by the handle 43. Figure 1 The bending block 42 is rotated clockwise from the side where the fixing block 31 is located to the other side of the fixing plate 32. During this process, the bending block 32 pushes the plate to bend around the outer side of the mandrel 2 to form a clamp.
