Description

Technical Field

[0001] This utility model relates to the field of tank trimming machine technology, and in particular to a brush bending tool. Background Technology

[0002] Commercially available beverages are typically packaged using two-piece cans (or simply two-piece cans). A two-piece can is a metal container consisting of a lid and a seamless, one-piece can body with a bottom. The production process for the can body is as follows: the raw material is first stretched into a pre-defined shape using a stretching device, and then it undergoes edge trimming processing using a trimming machine.

[0003] A star wheel device is installed in the arc-shaped recess of the inlet section between the upper and lower guide rails of the trimming machine's outlet device. The star wheel device works in conjunction with the guide rails to transport the can body. Given the relatively high conveying speed of the star wheel device, the can body may collide with the guide rails during transport. Therefore, a cushioning brush needs to be installed on the guide rails. The brush handle is pressed against the guide rail by a pressure plate, and its shape is a fan-shaped ring corresponding to the guide rail. Due to wear and tear during use, the brushes need to be replaced promptly to ensure the quality of the can body. However, due to their special shape, the demand for these brushes is small and cannot be replenished through market procurement, thus affecting the normal operation of the trimming machine. Summary of the Invention

[0004] This utility model provides a brush bending tool to overcome the above-mentioned technical problems.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A brush bending tool includes a concave die and a convex die;

[0007] The die has an inwardly concave arc-shaped recess;

[0008] The punch has a receiving cavity for accommodating the strip brush, and the die can be inserted into the receiving cavity. The inner wall of the receiving cavity has two arc-shaped protrusions corresponding to the arc-shaped recess. The gap between the two arc-shaped protrusions can accommodate the bristles of the strip brush, and the distance between the two arc-shaped protrusions is less than the thickness of the strip brush handle.

[0009] Furthermore, the punch includes two punch plates and two partition plates detachably connected to the punch plates. The punch plates are provided with arc-shaped protrusions, and the partition plates are located between the two punch plates. The two partition plates are respectively disposed at both ends of the punch plates.

[0010] The two convex templates and the two partitions form a receiving cavity.

[0011] Furthermore, the lengths of both the arc-shaped recess and the arc-shaped protrusion are greater than the length of the brush handle.

[0012] Furthermore, the die or the punch is provided with connecting bolts for connecting to the press head of the stamping machine.

[0013] Furthermore, the convex template and the partition are connected by screws.

[0014] Beneficial Effects: The brush bending tool provided by this utility model has a receiving cavity inside the punch for accommodating the strip brush. The arc-shaped protrusions within this receiving cavity cooperate with the arc-shaped recesses on the die to form a forming cavity for bending the strip brush handle. The gap between the two arc-shaped protrusions allows the brush bristles to be accommodated, preventing damage during bending. By using commercially available straight-handled strip brushes to manufacture the fan-shaped handle brushes required for edge trimming machines, this invention solves the problem of not being able to replenish edge trimming machine brushes through market procurement.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] This embodiment provides a brush bending tool, such as Figure 8 As shown, it includes a concave die 1 and a convex die 2;

[0032] like Figure 5 As shown, the die 1 has an inwardly concave arc-shaped recess 11;

[0033] The punch 2 has a receiving cavity for accommodating the strip brush A, and the die 1 can be inserted into the receiving cavity, such as... Figure 2 and Figure 3 As shown, the inner wall of the receiving cavity is provided with two arc-shaped protrusions 21 corresponding to the arc-shaped recess 11, such as... Figure 3 As shown, the gap between the two arc-shaped protrusions 21 can accommodate the bristles A2 of the strip brush A, and the distance between the two arc-shaped protrusions 21 is less than the thickness of the brush handle A1 of the strip brush A, so that the arc-shaped protrusions 21 can act on the brush handle A1 without damaging the bristles A2.

[0034] This embodiment provides a brush bending tool with a receiving cavity inside the punch 2 for accommodating a strip brush A. The arc-shaped protrusion 21 within this receiving cavity cooperates with the arc-shaped recess 11 on the die 1 to form a forming cavity for bending the handle A1 of the strip brush A. The gap between the two arc-shaped protrusions 21 allows the bristles A2 of the strip brush A to be accommodated, preventing damage to the bristles A2 during bending. By using a commercially available straight-handled strip brush A, a fan-shaped handle brush required for an edge trimming machine can be manufactured, overcoming the problem that brushes for edge trimming machines cannot be replenished through market procurement.

[0035] Specifically, such as Figure 4 As shown, the punch 2 includes two punch plates 22 and two partition plates 23 detachably connected to the punch plates 22, as follows: Figure 6 As shown, the convex template 22 is provided with an arc-shaped protrusion 21, and the partition 23 is located between the two convex templates 22. The two partitions 23 are respectively disposed at both ends of the convex template 22.

[0036] The two protruding templates 22 and the two partitions 23 together form a receiving cavity. By using screws to detachably connect the protruding templates 22 and partitions 23 (the protruding templates 22 have through holes, and the partitions 23 have threaded holes), the strip brush A does not need to be inserted into the punch 2 by insertion. Instead, one protruding template 22 can be removed from the punch 2, the strip brush A can be placed on the punch 2, and then the removed protruding template 22 can be reinstalled, so that the strip brush A is clamped between the two protruding templates 22. This design not only avoids potential damage to the bristles during insertion but also allows for appropriate reduction of size during design. Figure 7 The thickness of the partition plate 23 shown is reduced to decrease the distance between the two convex templates 22 (so that the strip brush A can be easily inserted into the receiving cavity without increasing the distance between the convex templates 22), effectively preventing the strip brush A from becoming loose in the convex mold 2.

[0037] Specifically, such as Figure 2 As shown, the lengths of the arc-shaped recess 11 and the arc-shaped protrusion 21 are both greater than the length of the brush handle A1 of the strip brush A, leaving room for the deformation of the brush handle A1.

[0038] Specifically, the die 1 or the punch 2 is provided with a connecting bolt 3 for connecting to the press head B of the stamping machine. In this embodiment, for example... Figure 1 As shown, the punch 2 is provided with connecting bolts 3 (at this time, the punch 2 is connected to the press head B of the stamping machine, and the die 1 is located below the punch 2; if the die 1 is provided with connecting bolts 3, then the die 1 is connected to the press head B of the stamping machine, and the punch 2 is located below the die 1), as... Figure 8 As shown, die 1 is placed on worktable C, and pressure is applied by the stamping machine to make... Figure 8 The straight brush handle in the middle is bent into Figure 9 The fan-shaped brush handle is shown.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
