Description

Technical Field

[0001] The utility model relates to a high-reliability bending tool, which is used for bending metallized shells and other products that need to be bent. Background Art

[0002] The tube legs need to be bent at 90°. Traditional bending tooling is mostly designed for a 90° bending angle. However, due to the high hardness of the metal, it is difficult for the finished product to form a 90° angle after the tube legs are bent, resulting in errors.

[0003] How to solve the current technical problem that the bending tooling of the metalized shell easily damages the ceramic insulator, resulting in a decrease in product yield has become a technical problem that needs to be solved urgently. Utility Model Content

[0004] The technical problem to be solved by this utility model is generally to provide a highly reliable bending fixture. To address the technical problem that existing metallized shell bending fixtures are prone to damaging ceramic insulators, this design adds a fixing bar that is screwed to secure the tube legs, ensuring that the root insulator is not stressed. Through theoretical design and practical testing, this design optimizes the 90° bending angle of the traditional bending fixture to 98°, offsetting the deformation and ensuring that the tube legs are precisely bent at 90°.

[0005] In order to solve the above problems, the technical solution adopted by the present invention is:

[0006] In order to achieve better bending, a high-reliability bending tool includes a main body as a support and a fixed horizontal bar on the main body;

[0007] The main body has a slot for storing the main body of the part to be bent and realizing horizontal positioning to ensure the bending size is consistent with the standard;

[0008] The part to be bent has an insulator portion, and a tube leg part to be bent is arranged at the outer end of the insulator portion;

[0009] The main body and the fixed horizontal bar clamp the exposed tube leg parts.

[0010] As a further improvement of the above technical solution:

[0011] In order to achieve compatibility, a transition portion is connected to the end of the card slot;

[0012] In order to realize the tube leg parts and avoid damaging the insulators, the upper surface of the main body has a positioning step;

[0013] In order to realize the matching horizontal bars, steps are provided at both ends of the main body, and threaded holes are provided on the steps;

[0014] The fixed horizontal bar has a through hole corresponding to the threaded hole;

[0015] In order to achieve better 90-degree shaping, guide slopes are provided on both sides of the main body, and the included angle a between the guide slope and the step portion is an acute angle.

[0016] In order to achieve more precise positioning and increase pressure, a reinforcing protrusion is provided in the middle of the fixed horizontal bar; the reinforcing protrusion and the positioning step correspondingly clamp the upper and lower ends of the same pipe leg member.

[0017] In order to improve the pressing processability, the lower end surface of the reinforcement protrusion is U-shaped.

[0018] This design uses a fixed horizontal bar to secure the tube leg with screws; the bending angle is optimized to 98° to offset deformation. This design secures the tube leg with a fixed horizontal bar, ensuring that the root insulator is not stressed; the 98° bending angle offsets deformation, allowing the tube leg to be precisely bent at 90°.

[0019] The utility model can protect the insulator and improve the product yield; the tube leg has high bending accuracy and can be bent accurately by 90 degrees. It has a reasonable design, low cost, is strong and durable, safe and reliable, simple to operate, saves time and effort, saves money, has a compact structure and is easy to use.

[0024] like Figure 1-3 As shown, the high-reliability bending tool of this embodiment includes a main body 2 as a support and a fixed horizontal bar 3 on the main body 2; the main body can be a carrier such as a block or a frame.

[0025] The main body 2 has a card slot 6 for storing the main body of the part to be bent 1; it can be matched according to the shape of the part to achieve lateral limitation, and gaskets and other parts can be added.

[0026] As a description of the workpiece, the part to be bent 1 has an insulator portion 5, and a tube leg part 4 to be bent is provided at the outer end of the insulator portion 5;

[0027] The main body 2 and the fixing horizontal bar 3 clamp the exposed tube leg 4, thereby preventing damage to the insulator.

[0028] A transition portion 7 is connected to the end of the slot 6 to be compatible with the lower part of the insulator;

[0029] The upper surface of the main body 2 has a positioning step 8, thereby supporting the tube leg 4.

[0030] Steps 9 are provided at both ends of the main body 2, and threaded holes 10 are provided on the step 9;

[0031] The fixed horizontal bar 3 has a through hole corresponding to the threaded hole 10; thereby achieving installation and fixing, in order to increase rigidity, the thickening setting can be

[0032] A guide slope 11 is provided on both sides of the main body 2. The angle a between the guide slope 11 and the step portion 9 is an acute angle, preferably 88 degrees.

[0033] A reinforcement protrusion 12 is provided in the middle of the fixed horizontal bar 3; the reinforcement protrusion 12 and the positioning step 8 correspond to clamp the upper and lower ends of the same tube leg 4, thereby reducing the contact area under force, increasing the pressure, and thus better clamping.
