Description

Technical Field

[0001] This utility model relates to the field of cable clamp processing technology, specifically a universal forming device for cable clamps. Background Technology

[0002] In the current cable clamp processing and production field, existing forming equipment generally suffers from multiple technical shortcomings, making it difficult to meet the comprehensive requirements of precision, efficiency, and adaptability in mass production. In terms of positioning accuracy, most devices lack a visual and high-precision positioning structure, relying solely on operator experience for adjustment. There is no clear scale line and positioning protrusion design for proper fit, and the fixing mechanism is mostly a single locking method, which is prone to slippage during processing due to gaps, causing clamp dimensional deviations. In mass production, the pass rate can only be maintained at around 85%, and a large number of defective products increase production costs. In terms of versatility, existing devices are mostly designed for single specifications, and the clamp positioning and forming components cannot be flexibly replaced or adjusted. When facing the processing needs of cable clamps with different diameters and bending angles, the entire set of devices needs to be replaced frequently, which not only increases the equipment purchase cost, but also leads to excessively long production changeover time, seriously restricting production efficiency. In terms of ease of operation, the existing equipment has a cumbersome positioning and adjustment process. The slider slides without a precise guide structure, often resulting in jamming or offset, requiring repeated position calibration. The forming operation relies heavily on complex mechanical transmission structures, which not only makes operation difficult, but also requires repeated adjustment of positioning parameters when continuously processing clamps of the same specification, further extending the processing cycle. The average daily processing volume of a single machine is only 60% of the ideal state. Insufficient structural stability and durability are also prominent issues. Some of the forming components of the device do not have a dedicated anti-deformation structure. During processing, the concentrated forming force can easily cause deformation of the bracket or mandrel, affecting the subsequent processing accuracy. The connection parts of the components lack effective wear-resistant protection design. After long-term use, wear will intensify, which will not only shorten the service life of the device (the average service life is only 1-1.5 years), but also cause fluctuations in the forming quality of the clamp. In terms of processing quality control, the existing clamping mechanisms are mostly single-point or asymmetrical support designs, which can easily cause uneven force on the clamps during clamping, resulting in tilting or local deformation. During the forming process, the mandrel arrangement is not reasonable enough, and the bending force is not applied evenly, often resulting in problems such as clamp wrinkles, cracks, or excessive bending angle deviations. It is difficult to meet the quality requirements of high-precision cable installation for clamps. These technical pain points have jointly driven the research and development and improvement of universal forming devices for cable clamps. Utility Model Content

[0003] To address the above problems, this utility model provides a universal forming device for cable clamps, thus solving the aforementioned issues.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a universal forming device for cable clamps, including a base, a positioning component on the base, a positioning clamping component at the upper end of the base, and a rotating forming component at the upper end of the base; The positioning component includes a bottom slider that is slidably connected to the base, an upper slider that is slidably connected to the bottom slider, and a fixed U-shaped component that is detachably connected to the upper slider; The positioning and clamping assembly includes a pressure plate, a support rod at the lower end of the pressure plate, and a tightening bolt connected to the lower end of the pressure plate; The rotary forming assembly includes a movable bracket with a handle connected to it. A contact mandrel and a rotating contact shaft are rotatably connected to the movable bracket, and anti-deformation connectors are provided at the upper ends of the contact mandrel and the rotating contact shaft.

[0005] Preferably, the base includes a sliding groove, a scale line, and a rotating fixing groove, and the bottom slider is provided with a triangular protrusion corresponding to the scale line.

[0006] Preferably, the right end of the bottom slider is connected to a screw rod, and a nut and a tightening nut are threadedly connected to the screw rod. A fixing seat is provided between the nut and the tightening nut, and the fixing seat is fixed to the base.

[0007] Preferably, the upper end of the bottom slider is provided with an isosceles trapezoidal groove, and the lower end of the upper slider is provided with an isosceles trapezoidal strip corresponding to the groove, and the upper slider slides in the groove of the bottom slider.

[0008] Preferably, the upper end of the contact mandrel is provided with a connecting seat, a washer is sleeved on the connecting seat, and the connecting seat is connected to the anti-deformation connector.

[0009] Preferably, the upper end of the rotating contact shaft is connected to a small spindle, the upper end of the small spindle is connected to an anti-deformation connector, and the anti-deformation connector is fixedly connected to the movable bracket.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The base is equipped with high-precision scale lines, and the triangular protrusion of the bottom slider enables visual positioning. Combined with the double locking structure of screw and double nuts, it can eliminate gaps and fix the position. At the same time, the isosceles trapezoidal groove guide design of the bottom slider and the upper slider can avoid sliding and offset, and ensure the dimensional consistency of the clamp processing.

[0011] 2. The fixed U-shaped part is detachable by bolts, and the appropriate model can be replaced according to different specifications of cable clamps; the distance between the contact core shaft and the rotating contact shaft can be adjusted by the anti-deformation connector to adapt to different bending angle requirements, without the need to customize equipment separately for a single specification of clamp.

[0012] 3. During positioning, parameters can be quickly set by sliding the slider and adjusting the bolts. The handle of the rotating forming component has anti-slip texture, and bending can be achieved by manual rotation. Moreover, when continuously processing clamps of the same specification, there is no need to repeatedly adjust the positioning, which greatly shortens the operation process and improves processing efficiency.

[0013] 4. The anti-deformation connectors are made of high-strength materials, and the small mandrel and connecting seat disperse the forming force to avoid deformation of the parts under stress; the washers at the connecting seat reduce friction loss, and the precision fit clearance design of each sliding part reduces wear of the parts and extends the overall service life of the device.

[0014] 5. The pressure plate forms a stable support through the support rod, and the tightening bolts achieve uniform clamping to prevent the clamp from tilting or deforming during processing; during forming, the contact mandrel and the rotating contact shaft are arranged in parallel, and the applied bending force is uniform, ensuring that the clamp bending angle is accurate and there are no wrinkles or cracks after forming.

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0018] Please see Figure 1 and Figure 2A universal forming device for cable clamps includes a base 1, which serves as the mounting foundation for the entire device. The top surface of the base 1 is precision-machined to ensure horizontality. A positioning component 2 is provided on the upper surface of the base 1. A positioning clamping component 3 is fixedly installed on the upper left side of the base 1, and a rotating forming component 4 is movably installed on the upper right side of the base 1 via a rotating fixing groove. The positioning component 2 includes a bottom slider 21 slidably connected to a groove in the base 1. The bottom of the bottom slider 21 has a guide structure matching the groove in the base 1. An upper slider 26 is slidably connected to the upper surface of the bottom slider 21. A fixing U-shaped component 27 is detachably connected to the top of the upper slider 26 via bolts. The opening size of the fixing U-shaped component 27 can be changed to a suitable model according to the profile specifications.

[0019] Please see Figure 1 and Figure 2 The positioning and clamping assembly 3 includes a horizontally arranged pressure plate 31. The lower end of the pressure plate 31 is provided with a support rod 32. The bottom of the support rod 32 is fixedly connected to the base 1 to form a stable support frame. A tightening bolt 33 is vertically connected to the center of the lower end of the pressure plate 31. The tightening bolt 33 passes through the pressure plate 31 and is adjusted for lifting through threads. The rotating forming assembly 4 includes an L-shaped movable bracket 47. A cylindrical handle 42 is fixed to the horizontal end of the movable bracket 47. The surface of the handle 42 is provided with anti-slip texture. The vertical end of the movable bracket 47 is rotatably connected to a contact spindle 43 and a rotating contact shaft 45 through a bearing. The contact spindle 43 and the rotating contact shaft 45 are arranged in parallel. An anti-deformation connector 48 is horizontally arranged at the upper end of the contact spindle 43 and the rotating contact shaft 45. The anti-deformation connector 48 is made of high-strength alloy material.

[0020] Please see Figure 1 and Figure 2The base 1 includes a T-shaped groove along its length, high-precision laser-engraved scale lines with an accuracy of 0.1mm, and a rotating fixing groove on the right side for mounting rotating components. The front end face of the bottom slider 21 has a triangular protrusion corresponding to the scale line, with the tip of the protrusion pointing towards the zero position of the scale line. This structure, through visual scale alignment, allows operators to quickly read the displacement of the bottom slider 21. Combined with the fine-tuning function of the screw 22, it achieves a positioning accuracy of ±0.05mm, significantly reducing the product scrap rate caused by positioning errors. It is particularly suitable for the standardized positioning requirements of mass production. The right end center of the bottom slider 21 is fixed to the screw 22 via a key connection. From right to left, the screw 22 is threaded with a nut 24 and a tightening nut 25. A fixing seat 23 is provided between the nut 24 and the tightening nut 25. The fixing seat 23 engages with the screw 22 via internal threads and is fixed to the base 1 by expansion bolts. By using a double-nut locking structure, the bottom slider 21 is coarsely positioned by first adjusting the nut 24, and then finely adjusted and locked by tightening the nut 25. This double fixing method can withstand the axial force generated during processing, avoid slight displacement of the bottom slider 21, and improve the positioning stability by more than 40%.

[0021] The upper end face of the bottom slider 21 has an isosceles trapezoidal groove along its width direction, with the side walls of the groove inclined at an angle of 60°. The lower end face of the upper slider 26 has an integrally formed isosceles trapezoidal strip corresponding to the groove, with a 0.02-0.05mm fitting gap between the trapezoidal strip and the groove. The upper slider 26 slides smoothly within the groove of the bottom slider 21 via the trapezoidal strip. The isosceles trapezoidal structure forms a natural anti-drop design, ensuring that the upper slider 26 slides along the set trajectory while withstanding vertical pressure. Precise control of the fitting gap ensures uniform sliding resistance, preventing jamming and making the lateral positioning adjustment of the profile smoother, improving adjustment efficiency by 30%.

[0022] Please see Figure 1 and Figure 2The upper end of the contact mandrel 43 is fixedly provided with a connecting seat 41 via a flange. The connecting seat 41 is made of 45# steel and has undergone heat treatment. A wear-resistant washer 44, made of polytetrafluoroethylene (PTFE), is fitted onto the contact surface between the connecting seat 41 and the anti-deformation connector 48. The connecting seat 41 is rigidly connected to the anti-deformation connector 48 via high-strength bolts. The PTFE washer 44 can reduce the coefficient of friction of the contact surface from 0.15 to 0.04, significantly reducing wear during rotation and avoiding abnormal noise caused by direct metal-to-metal contact. The rigid connection design of the connecting seat 41 controls the radial runout of the contact mandrel 43 to within 0.03mm, ensuring the consistency of the forming dimensions. The upper end of the rotating contact shaft 45 is positioned and connected to a small mandrel 46 via a shoulder. The small mandrel 46 and the rotating contact shaft 45 are interference-fitted. The upper end of the small mandrel 46 is movably connected to the anti-deformation connector 48 via a bearing. The anti-deformation connector 48 is welded to the movable bracket 47 to form an integral structure. This multi-point connection design distributes the force on the rotating contact shaft 45 to the entire anti-deformation connector 48. Combined with the use of high-strength materials, it can increase the component's resistance to deformation by 50%. Even when processing thick-walled profiles, it can ensure that the forming angle error does not exceed ±0.5°, effectively improving the product qualification rate.

[0023] When using this device for positioning and forming profiles, the following procedures must be followed: First, prepare the equipment by checking that the base 1 slide is clean and free of debris, ensuring that the screw 22, nut 24, and tightening nut 25 of the positioning component 2 rotate smoothly, and that the contact spindle 43 and contact shaft 45 of the forming component 4 rotate flexibly. Also, ensure that the anti-slip texture of the handle 42 is intact and that the anti-deformation connector 48 is not loose or deformed. Simultaneously, select the appropriate fixing U-shaped part 27 according to the specifications of the profile to be processed and install it on the upper slide block 26 with bolts. If the profile is thick, replace it with a thicker washer 44. Next, position the profile by loosening the nut 24 and tightening nut 25. Push the bottom slider 21 to slide along the groove of the base 1. Align the triangular protrusion at the front end of the bottom slider 21 with the scale line of the base 1 to determine the initial longitudinal position. For example, align the bending point with the mark. Then tighten the nut 24 to make it fit tightly against the fixing seat 23 to achieve rough fixing. Then rotate the top tightening nut 25 to lock in the reverse and eliminate the gap of the screw 22 to complete fine fixing. After that, push the upper slider 26 to slide along the isosceles trapezoidal groove of the bottom slider 21. Adjust the lateral position of the fixing U-shaped part 27 to fit the side contour of the profile. After the position is determined, fix it with the locking bolt on the side of the upper slider 26. After positioning, perform the clamping operation and put the profile to be processed into the opening of the fixing U-shaped part 27. Inside, make it fit against the upper surface of the bottom slider 21 and align the processing position with the lower part of the contact mandrel 43 and the rotating contact shaft 45. Then rotate the tightening bolt 33 of the positioning clamping assembly 3 to drive the pressure plate 31 to slowly press against the upper surface of the profile. The clamping force should be such that the profile is not loose. The support rod 32 ensures that the pressure plate 31 is horizontally stressed to prevent the profile from tilting. Then, perform rotational forming. According to the bending angle requirements, adjust the distance between the contact mandrel 43 and the rotating contact shaft 45 through the reserved hole of the anti-deformation connector 48. The operator holds the handle 42 and slowly rotates it towards the profile. During the rotation, the rotating contact shaft 45 rotates around the movable bracket 47, cooperating with the contact mandrel 43. 3. Apply uniform bending force to the profile. The anti-deformation connector 48 distributes the force through the small mandrel 46 and the connecting seat 41 to prevent the component from deforming. When the handle 42 is rotated to the preset angle, the scale of the rotating fixing groove of the base 1 can be used to judge. Hold for 10-15 seconds to ensure the plastic deformation of the profile is stable. Finally, reset and remove the material. Rotate the bolt 33 in the opposite direction to lift the pressure plate 31 and remove it from the profile. Rotate the handle 42 in the opposite direction to return the rotating contact shaft 45 to the initial position. Loosen the locking bolt of the upper slider 26 and slide it outward to remove the formed profile. If it is necessary to continuously process profiles of the same specification, the positions of the bottom slider 21 and the upper slider 26 can be kept unchanged and the subsequent steps can be repeated. During use, it is important to remove burrs from the profile surface before processing to prevent scratching the groove or components. After each processing, clean the surface debris of the contact mandrel 43 and rotating contact shaft 45 and apply a small amount of lubricating oil for maintenance. For high-strength profiles, multiple small-angle bends should be performed to avoid excessive force that could damage the components. Through this operating procedure, the device can achieve high-precision positioning and stable forming of the profile, meeting the high requirements for dimensional consistency in mass production.
