In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0033] The present embodiment provides a pre-bending clamp, as shown in the drawings, which comprises a bracket assembly 10, a pre-bending assembly 20 and a binding belt 30. The two ends of the bracket assembly 10 are provided with the pre-bending assembly 20, the two pre-bending assemblies 20 are oppositely provided with openings 211, the two ends of the workpiece 100 can be correspondingly clamped into the openings 211, and the clamping force of the pre-bending assembly 20 can make the middle part of the workpiece 100 bend away from the bracket assembly 10; the binding belt 30 can pass around the side of the workpiece 100 away from the bracket assembly 10, and the pre-tightening force of the binding belt 30 can make the workpiece 100 bend along the preset arc. Figure 1 In this structure, the two ends of the bracket assembly 10 can fix the pre-bending assembly 20, the workpiece 100 can be installed between the two pre-bending assemblies 20 through the openings 211, and the two pre-bending assemblies 20 can preliminarily form the workpiece 100 to bend away from the bracket assembly 10 through the interactive pre-bending ability; in addition, the binding belt 30 can tightly adhere to the side of the workpiece 100 away from the bracket assembly 10 and re-bend the workpiece 100 through its own pre-tightening force, so that the workpiece 100 can uniformly bend along the preset arc, thereby avoiding the difference in local bending state and achieving good pre-bending effect, thereby improving the efficiency of the spray forming and ensuring the yield.
[0034] To simplify the specific structure, as shown in the drawings, the bracket assembly 10 comprises a support column 11, a movable piece 12 and a supporting piece 13, the movable piece 12 is arranged at both ends of the support column 11 along the length direction, and the supporting piece 13 is arranged at the middle part of the support column 11. When the pre-bending assembly 20 clamps the workpiece 100, the supporting piece 13 abuts against and supports the workpiece 100, so that it can bend away from the support column 11. In this structure, the support column 11 is located on one side of the workpiece 100, and the pre-bending assembly 20 is located at both ends of the support column 11, which can maximize the simplification of the connection structure; and the supporting piece 13 is arranged at the middle part of the support column 11, so that when the pre-bending assembly 20 clamps the workpiece 100, the supporting piece 13 can abut against and support the inner side of the workpiece 100 (the side close to the bracket assembly 10), and thus the workpiece 100 can be pre-bent by the pre-bending assembly 20 at both ends and the supporting piece 13, thereby improving the pre-bending effect on the basis of simplifying the tool structure, so that the target bending arc can be more easily achieved.
[0035] Figure 1 In this structure, the two ends of the bracket assembly 10 can fix the pre-bending assembly 20, the workpiece 100 can be installed between the two pre-bending assemblies 20 through the openings 211, and the two pre-bending assemblies 20 can preliminarily form the workpiece 100 to bend away from the bracket assembly 10 through the interactive pre-bending ability; in addition, the binding belt 30 can tightly adhere to the side of the workpiece 100 away from the bracket assembly 10 and re-bend the workpiece 100 through its own pre-tightening force, so that the workpiece 100 can uniformly bend along the preset arc, thereby avoiding the difference in local bending state and achieving good pre-bending effect, thereby improving the efficiency of the spray forming and ensuring the yield.
[0036] To further improve the pre-bending effect, the movable piece 12 is movably connected with the support 11. When the thickness of the workpiece 100 is large and the bending resistance is strong, the movable piece 12 can drive the pre-bending assembly 20 to move towards the support 11, so that the abutting force between the support piece 13 and the workpiece 100 is increased, thereby facilitating the bending of the workpiece 100. Conversely, if the thickness of the workpiece 100 is small and the bending resistance is weak, the movable piece 12 can be moved away from the support 11, so that the abutting force between the support piece 13 and the workpiece 100 is reduced, thereby avoiding the workpiece 100 from being broken due to excessive force and improving the user experience.
[0037] It should be noted that in the present embodiment, the movable piece 12 is connected perpendicularly with the support 11 and can move along the thickness direction of the support 11. This arrangement not only simplifies the structure, but also ensures that the workpiece 100 does not come off the opening 211 of the pre-bending assembly 20 during movement of the movable piece 12, thereby ensuring good pre-bending effect.
[0038] To further improve the pre-bending ability, as shown in Figure 1 , the pre-bending assembly 20 can rotate around the connection position with the movable piece 12. When the pre-bending of the workpiece 100 cannot be completed by moving the movable piece 12 along the thickness direction of the support 11 alone, the pre-bending assembly 20 can be rotated for secondary adjustment, thereby improving the actual pre-bending effect. In combination with the adjustment of the movable piece 12 and the binding belt 30, the workpiece 100 can be bent to the expected radius more quickly and conveniently, thereby improving the pre-bending convenience.
[0039] In addition, as shown in Figure 1 , the pre-bending assembly 20 includes a pre-bending clamp 21, and the opening 211 is arranged in the pre-bending clamp 21, and the pre-bending clamp 21 can adjust the opening degree of the opening 211. Since the opening degree of the opening 211 is adjustable, the two ends of the workpiece 100 can be conveniently clamped into the opening 211, thereby improving the pre-bending efficiency and the convenience of pre-bending.
[0040] Specifically, as shown in Figure 1 , the pre-bending assembly 20 includes an adjusting piece 22, which is detachably arranged in the opening 211 of the pre-bending clamp 21, and the adjusting piece 22 can adjust the opening degree of the opening 211. In this structure, the opening degree of the opening 211 can be changed by changing the specific position of the adjusting piece 22 in the opening 211, thereby improving the convenience of use. It should be noted that in the present embodiment, the adjusting piece 22 is a bolt, which can be screwed to move in the opening 211, thereby changing the space occupied by the adjusting piece 22 in the opening 211, so that the opening degree of the opening 211 can be quickly and conveniently adjusted to install and fix the workpiece 100, thereby improving the convenience of use.
[0041] To facilitate the installation of the binding belt 30, as shown inFigure 1 The pre-bending clamp 21 is provided with a first through hole 212, and the binding belt 30 can pass through the side of the workpiece 100 away from the support assembly 10 and pass through the first through hole 212. In this structure, the binding belt 30 can be fixed through the first through hole 212, thereby simplifying the installation operation of the binding belt 30 and facilitating the fixing of the binding belt 30.
[0042] In addition, as shown in the drawings, Figure 1 Both ends of the support column 11 are provided with a second through hole 111, and the binding belt 30 can pass through the first through hole 212 and the second through hole 111 in sequence, so that the workpiece 100 is bent along the preset arc. This kind of setting can further ensure the stability of the overall structure, expand the operation space of both ends of the binding belt 30, and thus improve the convenience of fixing from both ends of the binding belt 30.
[0043] In addition, as shown in the drawings, Figure 1 The pre-bending clamp further comprises a locking member 40, and the two ends of the binding belt 30 passing through the second through hole 111 can be locked and fixed by the locking member 40 on the side of the support column 11 away from the workpiece 100. This kind of setting reasonably uses the space on the other side of the support column 11, thereby improving the space utilization rate, simplifying the structure between the support column 11 and the workpiece 100, and ensuring the convenience of use. In addition, after the shot forming is completed, the binding belt 30 can be removed by disassembling the locking member 40, which is simple and convenient.
[0044] The use process of the pre-bending clamp in the embodiment is described in combination with the drawings:
[0045] First, the workpiece 100 is preliminarily fixed by the pre-bending clamp 21;
[0046] Secondly, the binding belt 30 is wound around the outer periphery of the workpiece 100 and passes through the first through hole 212 and the second through hole 111, and is fixed on the other side of the support column 11 by the locking member 40;
[0047] Finally, the rotation angle of the movable member 12 and the pre-bending clamp 21 is repeatedly adjusted, so as to reach the target prestress and make the workpiece 100 bend along the preset arc.
[0048] In summary, the pre-bending clamp in the embodiment not only has good pre-bending effect, but also has good shot forming effect and high yield.
[0049] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and replacements can be made without departing from the protection scope of the present application. Here, it is not necessary and also impossible to enumerate all the implementation modes. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application claim.
