Description

Technical Field

[0001] The utility model relates to a shaping tool for arc-shaped thin-wall products, belonging to the technical field of arc-shaped thin-wall product shaping. Background Art

[0002] A certain curved thin-walled product consists of a welded curved thin-walled shell, a light-emitting element mounted on the shell, and a small strip of carbon felt insulation.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figure 1-8 As shown, the shaping tool for arc-shaped thin-walled products of the present invention includes a base 3, an outer clamping ring 4, an inner clamping ring 8, a pressing block 9 and a support 2.

[0021] Two parallel pressure strips 13 are mounted on the top surface of the base 3, forming a guide groove with the top surface of the base 3. The pressure strips 13 are fixed to the base 3 by screws 12. A threaded hole 31 is located at the center of the bottom surface of the guide groove (i.e., the top surface of the base 3).

[0022] The outer clamping ring 4 includes two clamping plates 41. Each clamping plate 41 is a rectangular plate-like structure with a semicircular groove 42 at one end. A boss 43 is provided at the edge of the semicircular groove on the clamping plate 41. The clamping plates 41 are spaced apart to form a clearance fit within the guide chute. The semicircular grooves 42 of the two clamping plates 41 are arranged opposite each other. A support 2 is provided at each end of the base. A compression screw 1 is threaded onto each support 2. The axis of the compression screw 1 is parallel to the guide direction of the guide chute. The compression screw 1 is pivotally connected to the corresponding clamping plate. A handle is provided at each opposing end of the two compression screws 1.

[0023] The two clamping plates 41 each have a convex-shaped groove 44 at their opposing ends. The convex groove 44 comprises a large and small interconnected portion. The compression screw 1 comprises a coaxially arranged threaded portion 1-1, a connecting portion 1-2, and a positioning head 1-3. The threaded portion 1-1 connects to the positioning head 1-3 via the connecting portion 1-2. Both the connecting portion 1-2 and the positioning head 1-3 are cylindrical, with the positioning head 1-3 having a larger diameter than the connecting portion 1-2. The positioning head 1-3 is positioned in the large portion of the convex-shaped groove, while the connecting portion 1-2 is positioned in the small portion of the convex-shaped groove.

[0024] The inner clamping ring 8 comprises two inner half-rings 81. The lower portion of the center hole of the inner clamping ring 8 is conical, with a larger upper portion and a smaller lower portion. The compression block 7 is positioned within the center hole of the inner clamping ring. The side surface 72 of the compression block 7 is conical, with a larger upper portion and a smaller lower portion. The compression block 7 is secured to the base via screws 6, which are threaded into the threaded holes. An annular retaining groove 71 is provided at the top of the center hole of the compression block 7. Two retaining blocks 51 are positioned at the lower end of the handle 5, and these retaining blocks 51 are positioned within the retaining groove 7, ensuring that the handle 5 can move the compression block 7 flexibly up and down.

[0025] When the utility model is used, the following steps are included:

[0026] 1) Assemble the illuminator 141 and the carbon felt insulation strip 142 in the arc-shaped thin-walled housing and place them on the base 3 so that they are located between the outer clamping ring 4 and the inner clamping ring 8;

[0027] 2) Turn the handle 11 and tighten the clamping screw 1 to push the two movable clamping plates 41 toward each other and clamp the outer arc surface of the arc-shaped thin-walled shell; press the handle 5 downward to make the side 72 of the clamping block 7 press the two inner half rings 81 of the inner clamping ring 8 to expand outward, pressing the inner arc surface of the arc-shaped thin-walled shell, and then tighten the screw 6 with a special wrench to fix the entire product and let it stand for 30-80 minutes to achieve the purpose of shaping the arc-shaped thin-walled shell.

[0028] 3) After the product is shaped, loosen the two tightening screws 1 and screw 6 and take out the arc-shaped thin-walled shell.
