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

[0023] See also Figure 1-4 A bezel outer bevel drawing die includes a mounting base 1, on which a bezel tilt positioning component 4, a front mounting frame 2 and a rear mounting frame 3 are installed.

[0024] The bezel tilt positioning assembly 4 includes an elastic collet 401 that is tilted, and the bezel 100 is sleeved on the elastic collet 401 , so that the elastic clamping arms on the elastic collet 401 are elastically stretched outwards to clamp the bezel 100 .

[0025] like Figure 3 、 4 As shown, the multiple elastic clamping arms of the elastic collet 401 are expanded within the circle of the bezel 100 to clamp the inner wall of the bezel 100 .

[0026] The tilted elastic collet 401 allows the outer inclined surface of the bezel 100 that requires wire drawing to be adjusted to an upper position when the bezel 100 is sleeved on the elastic collet 401 along the length direction of the elastic collet 401 .

[0027] The front mounting frame 2 is connected to a wire drawing direction positioning plate 14 located above the elastic collet 401 . A guide hole 15 running through the wire drawing direction positioning plate 14 is formed at a portion corresponding to the elastic collet 401 .

[0028] The rear mounting frame 3 is provided with front and rear guide rails 5 , and a slide seat 6 is slidably provided on the front and rear guide rails 5 .

[0029] like Figure 1 、 3 As shown, at least two guide rods are connected to the top of the rear mounting frame 3, and the guide rods are arranged front and back. Guide holes corresponding to the guide rods are passed through the front and back of the slide 6. After the guide rods are passed through the corresponding guide holes, the guide rods are connected to the rear mounting frame 3 to form front and rear guide rails.

[0030] A rotating shaft seat 7 is provided on the slide 6, and a connecting arm 8 is rotatably connected to the rotating shaft seat 7. The connecting arm 8 is a horizontally rotating connection setting, and one end of the connecting arm 8 extends forward to above the drawing direction positioning plate 14.

[0031] The guide hole 15 is provided with a guide member 9 that cooperates with the guide hole 15. The upper part of the guide member 9 is installed on the connecting arm 8. The lower part of the guide member 9 is connected to the drawing head 10 that passes through the guide hole 15 downward, or the lower part of the guide member 9 passes through the guide hole 15 downward and is connected to the drawing head 10, wherein the guide hole 9 extends horizontally on the drawing direction positioning plate 14 to form a drawing path 11 and an avoidance path 12 connected to the drawing path 11, and the guide member 9 can move horizontally along the drawing path 11, and move horizontally along the avoidance path 12.

[0032] like Figure 1 、 2 As shown, when the guide member 9 is in the wire drawing path, the wire drawing head 10 contacts the outer inclined surface of the bezel 100 to perform the wire drawing operation.

[0033] When it is necessary to replace the bezel 100 or switch between different drawing positions of the bezel 100, the guide member 9 can be moved to the avoidance path 12 so that the drawing head 10 is horizontally away from the bezel 100 and the elastic collet 401, thereby enabling the replacement of the bezel 100 or switching between different drawing positions of the bezel 100.

[0034] The connecting arm 8 is also connected to an operating handle 13, which is arranged at the front end of the connecting arm 8. The operating handle 13 is an operating rod arranged up and down. The operating handle 13 can more conveniently drive the guide member 9 on the connecting arm 8 to move on the drawing path 11 and the avoidance path 12.

[0035] When wire drawing is required, the bezel 100 can be clamped by the elastic collet 401, and then the connecting arm 8 or the operating rod is operated to move the drawing head 10 to the drawing path 11, and the guide member 9 is moved accordingly on the drawing path 11, so that the drawing head 10 below performs the corresponding drawing operation on the outer inclined surface of the bezel 100.

[0036] By means of the front and rear guide rails 5 arranged front and rear, and the connecting arm 8 arranged for horizontal rotation, the guide member 9 is restricted to horizontal movement when moving on the drawing path 11, and cannot move in the up and down directions. That is, when the drawing head 10 draws the outer inclined surface of the bezel 100, the position and force of each drawing can be better guaranteed, which is more conducive to ensuring that the drawing effect is uniform or close to uniform.

[0037] It is worth noting that when the guide member 9 moves back and forth in the horizontal direction, it can be understood that the distance of the guide member 9's back and forth movement is the same as, or nearly the same as, the distance of the slide 6's back and forth movement on the front and rear guide rails 5. When the guide member 9 also moves left and right in the horizontal direction (e.g., a combination of front and back and left and right movement), due to the length limitation of the connecting arm 8, the distance of the guide member 9's back and forth movement is usually different from the distance of the slide 6's back and forth movement on the front and rear guide rails 5. Therefore, when setting the length of the front and rear guide rails 5, that is, when setting the distance of the slide 6's back and forth movement on the front and rear guide rails 5, it should be set as long as possible to ensure that the guide block 9 can move smoothly along the wire drawing path 11 and the avoidance path 12.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
