Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-2 This utility model provides an embodiment of a U-bolt forming device, including a moving module 1. The moving module 1 is one of the key components of the entire forming device, providing an installation foundation and support for other components such as the forming assembly 3. It can be connected to an external power device to drive the forming assembly 3 to move downwards and perform molding operations such as forming the U-bolt. A fixed mold assembly 5 is provided on the lower side of the bottom end of the moving module 1. The upper surface of the moving module 1 is provided with a mounting hole 2, which is used to install and fix the moving module 1 to the corresponding drive equipment or other support structure, ensuring that the moving module 1 can move up and down stably and accurately during operation, providing a stable power transmission and support foundation for the normal operation of the entire forming device. The lower surface of the moving module 1 is provided with the forming assembly 3, which is used as a whole to perform forming operations on the U-bolt. Through the synergistic action of each component, the bolt can be bent and formed, and the shape, size and precision of the formed bolt can be adjusted according to different needs.

[0025] Reference Figures 1-3The forming assembly 3 includes a support frame 31, which provides a stable mounting base for subsequent components such as the moving mold 34, ensuring the overall structural stability of the forming assembly 3 and enabling it to withstand the pressure and impact generated during the forming process. The support frame 31 is fixedly installed on the lower surface of the moving mold 1, and the moving mold 34 is fixedly installed at the bottom end of the support frame 31. An adjusting plate 35 is slidably connected to the inner wall of the moving mold 34. The front surface of the adjusting plate 35 is threadedly connected to a wheel 33 via a lead screw 32. The lead screw 32 rotates by rotating the wheel 33, thereby allowing the adjusting plate 35 connected to it to move in the front-back direction of the moving mold 34, realizing the adjustment of the position of the adjusting plate 35. Precise adjustments are made to control the size and shape during molding, adapting to the molding requirements of U-bolts of different specifications. The wheel 33 allows operators to manually control the rotation of the lead screw 32, thereby adjusting the position of the adjusting plate 35. This design makes the adjustment process more convenient and intuitive, facilitating precise control of the molding dimensions. A limit frame 36 is fixedly installed at the upper end of the moving mold 34. The limit frame 36, installed at the upper end of the moving mold 34, restricts the movement range of the adjusting plate 35, preventing the adjusting plate 35 from exceeding the reasonable range during movement. This avoids problems such as equipment damage or poor molding effect due to excessive movement, thus protecting the equipment and ensuring molding quality.

[0026] Reference Figures 1-3 The moving mold 34, as the core component of the forming assembly 3, provides a sliding track for components such as the adjusting plate 35 on its inner wall, guiding the adjusting plate 35 to move along a predetermined trajectory. Simultaneously, it cooperates with the fixed mold assembly 5 to perform the forming operation on the U-bolt. Its shape and size directly affect the appearance and precision of the formed U-bolt. Multiple sets of sponge pads 37 are detachably connected to the rear surface of the adjusting plate 35. The sponge pads 37 act as buffers and protectors, reducing rigid collisions between the adjusting plate 35 and the U-bolt blank during the forming process, preventing scratches or other damage to the blank surface. They also absorb impact to a certain extent, improving the stability and precision of the forming process. Multiple sets of ball bearings 38 are rolled near the multiple sets of sponge pads 37 on the rear surface of the adjusting plate 35. When the adjusting plate 35 moves, the ball bearings 38 reduce friction between the adjusting plate 35 and the sponge pads 37, as well as with other components, making the movement of the adjusting plate 35 smoother, improving the operating efficiency and service life of the equipment, and ensuring the relative positional accuracy of each component during the forming process.

[0027] Reference Figures 2-4The fixed mold assembly 5 includes a fixed template 57, which is fixedly installed on the upper surface of the base plate 4. The fixed template 57 is the main component of the fixed mold assembly 5. Its inner wall provides space for the installation and movement of components such as the telescopic rod 51 and the forming template 53. At the same time, it cooperates with the moving module 1 and the forming assembly 3 to form a complete forming cavity, ensuring the U The bolt can be bent into a predetermined shape and size during the forming process. A base plate 4 is fixedly connected to the lower surface of the fixed template 57, providing a stable support foundation for the fixed mold assembly 5, ensuring that the fixed mold assembly 5 remains stationary during the forming process. Simultaneously, it can be connected to an external workbench or other fixed device via fixing bolts 56, enhancing the stability of the entire device and ensuring the accuracy and reliability of the forming operation. Fixing bolts 56 are detachably connected to the left and right ends of the upper surface of the base plate 4. A telescopic rod 51 is fixedly installed on the lower inner wall of the fixed template 57. The telescopic rod 51 is elastically connected to the forming template 53 via a spring 52. The top end of the spring 52 is fixedly connected to the lower surface of the forming template 53, and the bottom end of the spring 52 is fixedly connected to the outer wall of the telescopic end of the telescopic rod 51. The forming template 53 is slidably connected to the inner wall of the fixed template 57. Utilizing the elastic properties of the spring 52, an upward elastic force is applied to the forming template 53 during the forming process, allowing the forming template 53 to move according to U... The forming requirements of the bolts allow for flexible adjustment of pressure and position to ensure forming accuracy and quality, while also providing a certain buffering effect to reduce the impact force on the equipment during the forming process.

[0028] Reference Figures 2-4 The forming template 53 is slidably connected to the inner wall of the fixed template 57. The forming groove 54 in the groove on its upper surface determines the specific shape and size of the U-bolt after forming. It is one of the core components of the forming operation. The forming groove 54 is provided in the groove on the upper surface of the forming template 53. The shape and size of the forming groove 54 match the U-bolt to be formed, providing a mold cavity for the forming of the U-bolt. Under pressure, the bolt blank can be bent and deformed according to the shape of the forming groove 54, and finally obtain a qualified U-bolt product. Two sets of auxiliary rollers 55 are rotatably connected to the left and right ends of the top of the inner wall of the fixed template 57. During the forming process of the U-bolt, the auxiliary rollers 55 can guide and support the bolt blank, so that the blank can smoothly enter the forming groove 54 and bend and form according to the predetermined trajectory. At the same time, it can also reduce the friction between the blank and the fixed template 57, improve the forming efficiency and quality, and prevent the blank from twisting or deforming during the forming process.

[0029] Working principle: The moving module 1 is fixed to an external power unit or support structure through the mounting holes 2 on it. The base plate 4 of the fixed mold assembly 5 is connected to the worktable or other fixed device by fixing bolts 56 to ensure the stability and reliability of the entire device. According to the specifications of the U-bolt, the wheel 33 in the forming assembly 3 is manually rotated to drive the lead screw 32 to rotate, so that the adjusting plate 35 moves in the moving mold 34 to precisely adjust its position to control the size and shape during forming. At the same time, the limiting frame 36 restricts the movement range of the adjusting plate 35 to prevent excessive movement. The external power unit drives the moving module 1 to move downward, and the forming assembly 3 moves downward and approaches the fixed mold assembly 5. The U-bolt blank is placed in the forming groove 54 of the fixed mold assembly 5. When the blank enters the forming groove 54, it is guided and supported by the auxiliary roller 55, and smoothly enters and begins to bend and form.

[0030] The moving mold 34 and the forming template 53 work together to apply pressure to the blank. The spring 52 provides an upward elastic force to the forming template 53 through the telescopic rod 51, so that the forming template 53 can flexibly adjust its position and pressure according to the deformation requirements of the blank, ensuring forming accuracy and quality. The sponge pad 37 and the ball bearing 38 on the adjusting plate 35 play a role in buffering and reducing friction during the pressing process, improving the stability and accuracy of the forming. When the U-bolt reaches the predetermined shape and size, the external power device drives the moving module 1 to move upward, the pressing component 3 separates from the fixed mold component 5, the formed U-bolt is taken out from the forming groove 54, the device is reset, and it is ready to carry out the next forming operation.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
