Description

Technical Field

[0001] This utility model relates to a mold, specifically a square tube pressing mold structure. Background Technology

[0002] In the cab frame structure of electric tricycles, in order to install the cab more stably, a convex square beam needs to be set in the cab as a structural reinforcement. The current processing method is to bend the tube twice using a tube bending machine. However, this method has large processing errors, poor consistency of the formed tubes, cumbersome operation, and low processing efficiency.

[0003] Currently, a utility model patent with publication number CN208067118U discloses a square tube bending mold, including a base, two clamping components, and a punch. The base has two upward-protruding support blocks at both ends, with a distance of 20-50cm between them. Grooves are formed along the length of the upper surface of each support block. Each clamping component is detachably fitted into a corresponding groove. A slot is formed on the upper surface of each clamping component to hold the square tube; the depth of the slot is equal to the height of the square tube. The ends of the two clamping components are in contact. The punch is located directly above the contacting ends of the two clamping components. After bending, the two clamping components, along with the bent square tube, are removed from the grooves in the base. Since they do not deform during bending, they are easily removed from the grooves. Then, the bent square tube is removed from the slots in the two clamping components. The square tube is completely secured in the slots with minimal deformation. The clamping components are small and lightweight, facilitating disassembly and removal of the bent square tube.

[0004] As can be seen from the above-disclosed technical content, the prior art, utility model with announcement number CN208067118U, involves a punch pressing the contact ends of two clamping parts. The two clamping parts, along with the square tube, tilt and rotate towards the center, causing the square tube to bend. After completion, the two clamping parts, along with the bent square tube, are removed from the base groove. However, this patent can only bend the square tube once at a time, and the bend is 90 degrees, making it unsuitable for processing the square beams of electric tricycle cabs. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a square tube forming mold structure that can stamp and form the square beam of the electric tricycle cab in one step, and has high consistency in bending, which can effectively improve the processing efficiency of the square beam of the electric tricycle cab.

[0006] To achieve the above objectives, this utility model provides a square tube forming die structure, comprising an upper die base plate, a guiding mechanism, a lower die base plate, a punch, punch side pressure blocks, an upper guide plate, a lower die guide, a die cavity, a lower die stop, and a square beam. The upper die base plate and the lower die base plate are respectively fixedly mounted on a stamping machine by screws. The upper die base plate is connected to the lower die base plate through the guiding mechanism. The punch is fixedly mounted in the middle of the upper die base plate, and punch side pressure blocks are respectively mounted at both ends of the punch. A die cavity is correspondingly arranged below the punch and the punch side pressure blocks. The lower die guide is fixedly connected to the front of the die cavity, and the lower die stop is fixedly mounted at the rear of the die cavity by a pad block. A gap is left between the die cavity and the lower die stop. The upper guide plate is fixedly mounted at the rear of the punch, and the upper guide plate corresponds to the gap reserved between the die cavity and the lower die stop.

[0007] In addition, the square tube forming mold structure proposed in the above embodiments of this utility model may also have the following additional technical features:

[0008] As a further improvement of this utility model, the guide sleeve of the guide mechanism is fixedly installed on the lower part of the upper base plate of the mold, and the guide sleeve covers the guide post fixedly installed on the lower base plate of the mold.

[0009] As a further improvement of this utility model, a mold cavity is provided on the surface of the concave mold.

[0010] As a further improvement of this utility model, the lower mold stop has a built-in magnet.

[0011] As a further improvement of this utility model, the surfaces of the punch and the punch side pressure block are smoothly transitioned.

[0012] By means of the above solution, this utility model has at least the following advantages: compared with conventional pipe bending machines, by setting a punch, a punch side pressure block and a die, which are pressed together under the action of a stamping machine, the material can be directly taken out after one stamping cycle is completed, and it has high pipe bending consistency, which can effectively improve the processing efficiency of square beams for electric tricycle cabs.

[0018] The structure of the square tube forming mold of this utility model is described below with reference to the accompanying drawings.

[0019] In Embodiment 1 of this application, as Figures 1 to 3 As shown, the square tube forming die structure (hereinafter referred to as "the present invention") includes an upper die plate 1 and a lower die plate 3. The upper die plate 1 and the lower die plate 3 are respectively fixedly installed on the stamping machine by screws. The upper die plate 1 is connected to the lower die plate 3 through a guide mechanism 2. A punch 4 is fixedly installed in the middle of the upper die plate 1. Punch side pressure blocks 5 are respectively installed at both ends of the punch 4. A die 8 is correspondingly arranged below the punch 4 and the punch side pressure blocks 5. A lower die guide 7 is fixedly connected to the front of the die 8. A lower die stop 9 is fixedly installed at the rear of the die 8 through a pad. A gap is left between the die 8 and the lower die stop 9. An upper guide plate 6 is fixedly installed at the rear of the punch 4. The upper guide plate 6 corresponds to the gap reserved between the die 8 and the lower die stop 9. This structure effectively solves the problems of wrinkling and deformation of square tubes and consistency.

[0020] A square tube bending die (hereinafter referred to as "the patent") with utility model announcement number CN208067118U uses a punch to press the contact ends of two clamping parts. The two clamping parts, along with the square tube, tilt and rotate towards the center, causing the square tube to bend. After completion, the two clamping parts and the bent square tube are removed from the base groove. However, this patent can only bend the square tube once at a time, and the bend is 90 degrees, which is not suitable for processing square beams for electric tricycle cabs. In contrast, this invention, by setting a punch 4, a punch side pressure block 5, and a die 8, applies pressure together under the action of a stamping press. After one stamping cycle, the material can be directly removed, and the bending consistency is high, which can effectively improve the processing efficiency of square beams for electric tricycle cabs.

[0021] This second embodiment is basically the same in structure as the first embodiment, the difference being that, as Figure 1 As shown, the guide sleeve of the guide mechanism 2 is fixedly installed on the lower part of the upper base plate 1 of the mold, and the guide sleeve covers the guide post fixedly installed on the lower base plate 3 of the mold.

[0022] To further optimize the working efficiency of this application and enable the square tube to be placed in place in one go, a mold cavity is provided on the surface of the concave mold 8. A magnet is built into the lower mold stop 9. To make the surface of the square tube smoother, the surfaces of the convex mold 4 and the convex mold side pressure block 5 have a smooth transition.

[0023] When in use, install the square tube forming mold structure into the corresponding position on the stamping machine, and the equipment can be put into use.

[0024] When this utility model is used, its specific operation is as follows:

[0025] In use, a square tube is placed on the punch 4. The upper die plate 1 moves downward, and the upper die guide plate 6 first inserts into the lower die guide 7. Then, the punch 4 on the upper die plate 1 begins to contact the square tube. When the die reaches the bottom dead center, the square tube has been formed into a square beam 10. Figure 4 As shown, the square tube is now surrounded on all sides. After processing, the mold continues to move upwards and removes the formed square beam 10, thus completing one cycle.

[0026] In summary, the square tube forming die structure of this utility model embodiment, by setting a punch 4, a punch side pressure block 5 and a die 8, together apply pressure under the action of a stamping machine. After one stamping cycle is completed, the material can be directly taken out, and it has high tube bending consistency, which can effectively improve the processing efficiency of square beams for electric tricycle cabs.
