Description

Technical Field

[0001] This utility model relates to the field of metal processing equipment technology, and specifically to a bending and forming device for metal jackets. Background Technology

[0002] In modern manufacturing, metal clips are widely used in various fields, including machinery manufacturing and the automotive industry. Metal clips are often referred to as wire harness clamps. They are generally L-shaped with a through hole at each end, and after machining, the middle section is annular, with the two through holes coaxial. Currently, there is a lack of specialized equipment for machining metal clips. Machining methods primarily rely on manual bending, requiring multiple clamping and adjustments, increasing operational complexity and time costs. This results in high labor intensity, low production efficiency, difficulty in guaranteeing machining accuracy, and poor product quality. Furthermore, manual bending using tools can easily damage the surface of the metal clip, affecting the product's appearance.

[0003] In order to overcome the shortcomings of existing technologies, there is an urgent need for a bending and forming device for metal jackets, which can improve the bending and forming efficiency and bending quality of metal jackets through a simplified and reasonable bending and forming device. Utility Model Content

[0004] The present invention aims to provide a bending and forming device for metal jackets, which effectively solves the problem of low processing quality and efficiency of metal jackets, and improves the bending and forming efficiency and bending quality of metal jackets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bending and forming device for metal jackets includes a frame, a clamping mechanism, and a bending mechanism. Both the clamping mechanism and the bending mechanism are mounted on the upper surface of the frame. The bending mechanism includes a rotating seat, a bending block, and a truncated cone. The rotating seat includes a fixed platform fixed to the frame and a rotating disk coaxially rotatably connected to the periphery of the fixed platform. The truncated cone is located at the center of the fixed platform. The bending block is located on the rotating disk, and a receiving space for inserting a metal jacket is provided between the bending block and the truncated cone. The clamping mechanism includes a positioning block, a clamping block, and a first driving mechanism. The positioning block is connected to the frame. The clamping surface of the positioning block has a positioning post with a through hole for engaging the metal jacket. The side of the positioning block away from the clamping block is tangent to the surface of the truncated cone and parallel to the clamping surface. The clamping block is connected to the free end of the first driving mechanism. The clamping surfaces of the clamping block and the positioning block are parallel.

[0007] The principle and advantages of this scheme are:

[0008] This design incorporates a bending and forming device based on the shape and structural characteristics of metal sleeves. Through positioning, clamping, and then bending, the bending and forming operation of metal sleeves is efficiently completed. The core of this solution lies in the clamping and rotating mechanism. This mechanism is formed by the cooperation of a drive mechanism, a rotating base, a clamping block, a positioning block, a bending block, and a truncated cone. The remaining components are arranged around the rotating base. The position of the positioning block is fixed according to the size of the metal sleeve. The positioning block has positioning posts for quickly fixing the metal sleeve. Then, the drive mechanism and clamping block are arranged. The first drive mechanism drives the clamping block to move, thus completing the first clamping operation. Next, the bending block is placed on the rotating disk of the rotating base. The bending block, in conjunction with the truncated cone, presses the metal sleeve and rotates it, completing the bending and forming operation. The advantages of this solution are that it can efficiently and quickly complete the bending and forming operation of metal sleeves without scratching them, greatly improving the efficiency and quality of metal sleeve bending and forming.

[0009] Preferably, as an improvement, the first drive mechanism includes a cylinder and a lever component, wherein the telescopic end of the cylinder is detachably connected to the force-bearing end of the lever component.

[0010] To reduce the overall size of the device, a first drive mechanism with a cylinder is used to drive the lever component. Both are compact and have stable performance, which can effectively drive the clamping block to complete the reciprocating clamping and releasing operation.

[0011] Preferably, as an improvement, the frame is further provided with a second drive mechanism for driving the bending mechanism. The second drive mechanism is a gear and rack mechanism. The frame is provided with a fixed shaft, the fixed table is coaxially fixed on the fixed shaft, the outer ring of the fixed shaft is coaxially provided with a bearing, the outer ring of the bearing is coaxially connected to a gear, the rotating disk is detachably connected to the end face of the gear, the upper surface of the rotating disk is flush with the upper surface of the fixed table, and the rack is connected to the free end of the second drive mechanism.

[0012] To further improve processing efficiency and quality and reduce labor intensity, a second drive mechanism is also provided. The second drive mechanism adopts a rack and pinion mechanism that can precisely adjust the stroke. The rotation of the gear drives the rotating disk to rotate, and the rotating disk drives the bending block to rotate, realizing automatic reciprocating bending and forming operation. It works in conjunction with the first drive mechanism to complete the clamping, bending and forming processing of the metal sleeve.

[0013] Preferably, as an improvement, the lower part of the bending block is provided with a protruding structure, and the rotating seat is provided with a limiting groove and a limiting block that cooperate with the protruding structure, and the height of the protruding structure is higher than the height of the limiting groove.

[0014] Due to the nature of bolted connections, directly fixing the bending block to the rotating seat can easily cause it to loosen and shift, resulting in deviations in the stress point during metal sleeve bending, thus affecting bending accuracy and the overall stability of the sheet metal. By adding a protruding structure and a limiting groove, the loosening of the bending block is effectively prevented, ensuring the accuracy and stability of the bending operation.

[0015] Preferably, as an improvement, the clamping surfaces and the rounded platforms of the clamping block and the positioning block are provided with Teflon tape.

[0016] The clamping block and the positioning block are provided with Teflon tape on their opposite surfaces and the rounded platform to prevent the device from scratching the metal jacket, thus providing protection. At the same time, it reduces friction, improves the smoothness of operation, and reduces wear.

[0017] Preferably, as an improvement, the bending block is a quadrangular prism with grooves on the facet close to the inverted frustum. Rollers are provided at both corners of the facet. When the bending block rotates with the rotating disk, the distance between the rollers and the inverted frustum is equal to the thickness of the metal sleeve.

[0018] Observations during actual use of the bending block's rotation trajectory and its final contact with the positioning block revealed that during rotation, the corner of the bending block near the inverted truncated cone directly contacts and rubs against the metal clamp, easily causing scratches and wear. Therefore, rollers were installed at both corners. These rollers press against the center of the metal clamp, and the bending block rotates with the rotating seat. The rollers move in an arc shape, closely adhering to the metal clamp, completing the bending and forming operation of the entire metal clamp. The contact between the bending block and the metal clamp during rotation becomes rolling friction, significantly reducing the coefficient of friction, effectively preventing scratches, and extending the equipment's service life.

[0019] Preferably, as an improvement, an adjustable limit rod coaxial with the rack is installed on the side wall of the frame opposite to the rack.

[0020] To increase the stability of the device, an adjustable limit rod coaxial with the rack is added to the side wall of the frame. This can effectively adjust the range of motion of the rack, prevent excessive displacement, ensure smooth operation of the device, and improve the stability and safety of the overall structure.

[0029] The following detailed description illustrates the specific implementation method:

[0030] The reference numerals in the accompanying drawings include: frame 1, clamping mechanism 2, metal clamp 3, bending mechanism 4, control mechanism 5, Teflon tape 6, limit rod 11, second drive mechanism 21, rack 22, positioning block 23, clamping block 24, gear 25, first drive mechanism 41, lever component 42, rotating seat 43, bending block 44, inverted frustum 45, positioning post 231, limit block 431, limit groove 432, fixed platform 433, rotating disk 434, roller 441, clamping controller 51, bending controller 52.

[0031] The basic implementation examples are as follows: Figure 1-8 As shown:

[0032] As attached Figure 1 and attached Figure 2 As shown, a bending and forming device for metal jackets includes a frame 1, a clamping mechanism 2, a bending mechanism 4, and a control mechanism 5. The frame 1 is generally a rectangular box, as shown in the attached figure. Figure 6 As shown, a second drive mechanism 21 is provided inside the rectangular box. The second drive mechanism 21 is a gear and rack mechanism. The clamping and rotating mechanism 2 is installed on the upper surface of the rectangular box, and the control mechanism 5 is installed on the lower side of the rectangular box. The clamping mechanism 2 includes a positioning block 23 and a clamping block 24. The bending mechanism 4 includes a rotating seat 43, a bending block 44, and a rounded frustum 45. The rotating seat 43 is divided into a coaxial fixed platform 433 and a rotating disk 434. A fixed shaft is provided on the frame 1. The fixed platform 433 is coaxially fixed on the fixed shaft of the frame 1. A bearing is coaxially provided on the outer ring of the fixed shaft. The outer ring of the bearing is coaxially connected to a gear 25. The rotating disk 434 is bolted to the end face of the gear 25. The upper surface of the rotating disk 434 is flush with the upper surface of the fixed platform 433, as shown in the attached figure. Figure 8As shown, the bending block 44 is generally a parallelogram prism with two screw holes at the top for fixing. A groove is formed on the edge near the inverted frustum 45, and rollers 441 are respectively provided at the two corners of the edge. When the bending block 44 rotates with the rotary disk, the distance between the rollers 441 and the inverted frustum 45 is equal to the thickness of the metal sleeve 3. The roller 441 closest to the inverted frustum 45 plays the main bending and shaping role, while the other roller 441 plays an auxiliary bending and shaping role, while preventing scratches on the metal sleeve 3. The distance between the roller 441 closest to the inverted frustum 45 and the inverted frustum 45 is equal to the thickness of the metal sleeve 3 to ensure overall machining accuracy. The lower end of the parallelogram prism has a protruding structure for easy installation. The inverted frustum 45 is installed and fixed at the center of the inner ring. The inverted frustum 45 mainly serves for positioning and shaping, ensuring that the center of the metal sleeve is circular after machining. The rotating disk can rotate with the gear 25. The rotating disk is provided with a limiting groove 432 and a limiting block 431 that cooperate with the protruding structure at the bottom of the bending block 44, which facilitates the installation, fixing and limiting of the bending block 44, effectively preventing the bending block from loosening and ensuring the accuracy and stability of the bending operation.

[0033] The driving mechanism includes a first driving mechanism 41 and a second driving mechanism 21. The first driving mechanism 41 includes a cylinder and a lever component 42. The cylinder drives the lever component 42 to rotate around the left fulcrum. The upper part of the clamping block 24 is fixed to the lower end of the lever component 42 by bolts. The cylinder-driven lever component 42 has a compact structure and fast response, enabling it to quickly complete the rotation of the lever component 42, thus improving the efficiency and stability of the clamping operation. (See attached diagram) Figure 7 As shown, the positioning block 23 is L-shaped, with a positioning post 231 on the side of the long end of the L-shape adjacent to the clamping block, used for quickly positioning the metal sleeve 3. The upper end of the positioning block 23 is fixed to the housing of the first drive mechanism 41 by bolts. When the lever component 42 rotates to clamp the metal sleeve 3 to be processed, the clamping surfaces of the positioning block 23 and the clamping block 24 are parallel. The cylinder drives the lever component 42 to drive the clamping block 24 to complete the clamping and releasing function. Teflon tape 6 is provided on the clamping surfaces and the rounded platform of the clamping block 24 and the positioning block 23 to prevent scratches on the metal sleeve, providing protection, reducing friction, improving the smoothness of operation, and reducing wear.

[0034] As attached Figure 6The lower part of the rotating seat 43 shown is a gear structure. The second drive mechanism 21 is a gear and rack mechanism used to drive the bending mechanism 4. The right end of the second drive mechanism 21 is connected to a rack 22 that cooperates with the gear 25. The second drive mechanism 21 drives the rack 22 to reciprocate, thereby realizing the rotation return function of the rotating seat 43. On the right side wall of the frame 1 opposite to the rack 22, there is an adjustable length limit rod 11 coaxial with the rack 22. The bending operation of the metal sleeve 3 can be completed by precisely controlling the stroke through the rack and gear mechanism. The movement range of the rack 22 can be adjusted by the limit rod 11 to prevent excessive displacement and improve the stability and safety of the overall structure. The clamping, rotation, and recovery functions of the entire device are accomplished by controlling the second drive mechanism 21 and the first drive mechanism 41 through the control mechanism 5. The control mechanism 5 includes a clamping controller 51 and a bending controller 52. Considering the differences in operators' habits and operating time, in order to simplify the single-person operation process and enhance safety, the clamping control and rotation control are set independently. After the metal sleeve 3 is installed, the operator can start the clamping control and rotation control by himself, thereby avoiding the metal sleeve 3 from starting to rotate and bend before it is correctly installed due to excessive waiting time or chaotic operation, and avoiding incomplete processing or even damage to the metal sleeve. In this way, the overall bending and forming quality and efficiency of the metal sleeve 3 can be improved.

[0035] In addition, different sizes of inverted truncated cone 45, positioning block 23 and clamping block 24 can be customized for metal sleeves 3 with different bending dimensions, and can be flexibly selected to meet the needs of different bending forming dimensions.

[0036] The specific implementation method is as follows:

[0037] As attached Figure 3 As shown, align the round hole at the short end of the L-shaped metal sleeve 3 with the positioning post 231 and clamp it in place. Then, activate the clamping controller 51. The clamping block 24, in conjunction with the positioning block 23, clamps the metal sleeve 3. Then, activate the bending controller 52. The second drive mechanism 21 drives the rack 22 to rotate the rotating seat 43. The bending block 44 rotates with the rotating seat 43, and the roller 441 on the bending block 44 presses against the metal sleeve 3 and slides. Figure 4 As shown, the bending and forming of the metal sleeve 3 is finally completed. Then, the second drive mechanism 21 drives the rack 22 to reset the rotating seat 43, and the first drive mechanism 41 drives the clamping block 24 to reset. The entire device re-enters the waiting state. By placing a new metal sleeve 3 and repeating the above operation, the bending and forming of the metal sleeve 3 can be completed efficiently in batches.
