Description

Technical Field

[0001] This utility model relates to the field of bending technology, specifically to a bending mechanism for processing chassis housings. Background Technology

[0002] A bending mechanism for processing chassis enclosures is typically used in the processing of sheet metal to achieve precise bending. When designing such a bending mechanism, factors such as the size of the sheet metal, the bending angle, accuracy requirements, and work efficiency need to be considered.

[0003] According to a public disclosure of a bending mechanism for processing agricultural machinery housings (Publication No.: CN 214488603 U), it includes a first support rod, a second support rod fixedly connected to the first support rod, a first bearing plate fixedly connected to the second support rod, a second bearing plate slidably connected to the upper surfaces of the two second support rods, a second fixing rod fixedly connected to the top of the two first support rods, a third fixing rod fixedly connected to the opposite side of the two second fixing rods, a limit rod fixedly connected to the opposite side of the two second fixing rods, and the bottom of the opposite side of the two limit rods fixedly connected to the second support rod.

[0004] The above-mentioned method, through the cooperation between components such as the first support rod and the second support rod, is insufficient to prevent displacement of the chassis during bending, which could lead to inaccurate bending or damage due to chassis movement. This method needs improvement. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a bending mechanism for chassis body processing, which solves the technical problem that the chassis cannot avoid displacement during the bending process in the prior art.

[0006] According to one aspect, at least one embodiment of the present invention provides a bending mechanism for processing chassis housings, including a support leg, an operating table fixedly connected to the top of the support leg, a bending anti-displacement component provided on the top of the operating table, the bending anti-displacement component including a vertical rod, one end of the vertical rod fixedly connected to the top of the operating table, a hydraulic cylinder fixedly connected to the side of the vertical rod, a bending head fixedly connected to the telescopic end of the hydraulic cylinder, a rectangular frame fixedly connected to the top of the operating table, a short rod fixedly connected to the side of the operating table, a motor fixedly connected to one end of the short rod, a double-acting lead screw fixedly connected to the output shaft of the motor, a threaded sleeve threadedly connected to the circumferential surface of the double-acting lead screw, a limit rod fixedly connected to the side of the motor, the end of the limit rod away from the motor passing through the side of the threaded sleeve, a fixing plate fixedly connected to the top of the threaded sleeve, a sliding groove provided on the top of the rectangular frame, a baffle plate fixedly connected to the top of the rectangular frame, and a placement platform fixedly connected to the top of the baffle plate.

[0007] For example, in at least one embodiment of the present invention, a bending mechanism for processing a chassis body is provided, which further includes: the bidirectional lead screw and the threaded sleeve are located on the inner wall of the rectangular frame; two threaded sleeves and fixing plates are provided and are symmetrical to each other along the vertical central axis of the bidirectional lead screw; the provision of two fixing plates is beneficial to the stable clamping of the two sides of the chassis body to prevent displacement.

[0008] The side of the threaded sleeve is slidably connected to the inner wall of the groove, the bending head is located at the top of the placement platform, and a switch is provided on the side of the hydraulic cylinder. The design of the switch facilitates direct control of the hydraulic cylinder.

[0009] The side of the fixing plate is fixedly connected with a protective pad. There are two protective pads, which are symmetrical to each other along the vertical central axis of the placement platform. The design of the protective pads helps to protect the clamped chassis.

[0010] The placement platform is located on the displacement trajectory of the bending head, the fixing plate and the protective pad are located on the side of the placement platform, and the shielding plate is located at the bottom of the placement platform. This design is beneficial for squeezing and bending the chassis placed on the placement platform when the bending head moves.

[0011] The placement platform is located on the displacement trajectory of the fixed plate. The top of the operating platform is fixedly connected with a frame rod. There are two frame rods, which are symmetrical to each other along the vertical central axis of the operating platform. This design is beneficial to firmly clamp the chassis and temporarily fix it when the fixed plate moves.

[0012] According to another aspect, at least one embodiment of the present invention also provides a bending mechanism for processing chassis housings, comprising: a dust removal and heat dissipation assembly disposed on the top of the operating table, the dust removal and heat dissipation assembly including an extrusion rod, one end of the extrusion rod being fixedly connected to the top of a fixing plate, an L-shaped rod being fixedly connected to the top of the frame rod, a rotating shaft being rotatably connected to the bottom of the L-shaped rod, an inclined rod being fixedly connected to the circumferential surface of the rotating shaft, and a fan blade being fixedly connected to the circumferential surface of the rotating shaft. The fan blades generate airflow to blow air onto the placement table and the bending head, thereby reducing the temperature generated during bending and removing dust from the placement table.

[0013] For example, in a bending mechanism for processing a chassis body provided in at least one embodiment of the present invention, the inclined rod is located on the displacement trajectory of the extrusion rod, and a plurality of fan blades are provided and arranged in a circumferential array on the circumferential surface of the rotating shaft. This design is beneficial to extruding the inclined rod when the extrusion rod moves.

[0014] A torsion spring is fixedly connected to the circumferential surface of the rotating shaft. The end of the torsion spring away from the rotating shaft is fixedly connected to the bottom of the L-shaped rod. The design of the torsion spring is conducive to the automatic reset of the rotating shaft when it is not compressed.

[0015] Two fan blades, inclined rods, and extrusion rods are provided. The fan blades are located on the top of the placement platform and bending head. Anti-slip pads are fixedly connected to the bottom of the support legs. The design of the anti-slip pads helps to prevent the entire device from tipping over and sliding.

[0016] The beneficial effects of the embodiments of this utility model are as follows: 1. In this utility model, through the cooperation of components such as the fixing plate, motor, and bidirectional lead screw inside the bending anti-displacement assembly, precise control by the hydraulic cylinder is achieved. This ensures that the up-and-down movement of the bending head is uniform and stable, thereby improving the accuracy of the bending process and ensuring that the shape and size of the machine box meet the requirements after bending. Starting the motor and driving the bidirectional lead screw to rotate forward can move the two threaded sleeves and the two fixing plates relative to each other, clamping the two sides of the machine box. This effectively prevents the machine box from shifting during the bending process and avoids inaccurate processing or damage caused by the movement of the machine box.

[0017] 2. In this utility model, the fan blades, rotating shaft, inclined rod, and extrusion rod inside the dust removal and heat dissipation component work together to achieve the effect of effectively removing heat through the air force generated by the fan blades, reducing the temperature of the hydraulic cylinder and bending head, ensuring stable operation, and avoiding equipment failure or efficiency reduction due to overheating. Dust and impurities often accumulate on the top of the placement platform. If this dust enters the interior of the equipment, it may have an adverse effect on the mechanical operation. By blowing air, these impurities can be effectively removed, keeping the working area clean and reducing the probability of failure. Attached Figure Description

[0027] like Figures 1-5 As shown, this invention illustrates a bending mechanism for processing chassis housings according to one embodiment of the present invention. The mechanism includes a support leg 1, with an operating platform 2 fixedly connected to the top of the support leg 1. A bending anti-displacement component 3 is provided on the top of the operating platform 2. The bending anti-displacement component 3 includes a vertical rod 31, one end of which is fixedly connected to the top of the operating platform 2. A hydraulic cylinder 32 is fixedly connected to the side of the vertical rod 31, and a bending head 33 is fixedly connected to the telescopic end of the hydraulic cylinder 32. A rectangular frame 34 is fixedly connected to the top of the operating platform 2, and short rods 3 are fixedly connected to the side of the operating platform 2. 5. A motor 36 is fixedly connected to one end of the short rod 35. A double-acting lead screw 37 is fixedly connected to the output shaft of the motor 36. A threaded sleeve 38 is threadedly connected to the circumferential surface of the double-acting lead screw 37. A limit rod 39 is fixedly connected to the side of the motor 36. The end of the limit rod 39 away from the motor 36 passes through the side of the threaded sleeve 38. A fixing plate 310 is fixedly connected to the top of the threaded sleeve 38. A sliding groove 316 is opened on the top of the rectangular frame 34. A baffle plate 312 is fixedly connected to the top of the rectangular frame 34. A placement platform 313 is fixedly connected to the top of the baffle plate 312.

[0028] In some examples, the bidirectional lead screw 37 and the threaded sleeve 38 are located on the inner wall of the rectangular frame 34. There are two threaded sleeves 38 and two fixing plates 310, which are symmetrical to each other along the vertical central axis of the bidirectional lead screw 37. The two fixing plates 310 help to clamp the two sides of the stable chassis to prevent displacement.

[0029] The side of the threaded sleeve 38 is slidably connected to the inner wall of the groove 316. The bending head 33 is located on the top of the placement platform 313. A switch 314 is provided on the side of the hydraulic cylinder 32. The design of the switch 314 is conducive to direct control of the hydraulic cylinder 32.

[0030] The side of the fixing plate 310 is fixedly connected with a protective pad 311. There are two protective pads 311, which are symmetrical to each other along the vertical central axis of the placement platform 313. The design of the protective pad 311 is beneficial to protect the clamped chassis.

[0031] The placement platform 313 is located on the displacement trajectory of the bending head 33. The fixing plate 310 and the protective pad 311 are located on the side of the placement platform 313, and the shielding plate 312 is located at the bottom of the placement platform 313. This design is beneficial to the squeezing and bending of the chassis placed on the placement platform 313 when the bending head 33 moves.

[0032] The placement platform 313 is located on the displacement trajectory of the fixed plate 310. The top of the operating platform 2 is fixedly connected with a frame rod 315. There are two frame rods 315, which are symmetrical about each other along the vertical central axis of the operating platform 2. This design is conducive to the stable clamping of the chassis and temporary fixation when the fixed plate 310 moves.

[0033] For example, such as Figures 1-5 As shown, the chassis to be bent is placed on top of the placement platform 313. Switch 314 is pressed, activating the hydraulic cylinder 32. The extension end of the hydraulic cylinder 32 extends and retracts, causing the bending head 33 to move up and down, facilitating the compression of the chassis and achieving bending. To prevent displacement of the chassis during bending, motor 36 is activated, driving it to rotate forward. The forward rotation of motor 36 drives the bidirectional lead screw 37 to rotate forward, causing the two threaded sleeves 38 and the two fixed plates 310 to move relative to each other. This causes the two threaded sleeves 38 and the two fixed plates 310 to move simultaneously towards the side closer to the placement platform 313. The placement platform 313 is located on the displacement trajectory of the two fixed plates 310. When the two fixed plates 310 move relative to each other… The machine casing placed on the placement table 313 can be clamped on both sides to prevent displacement. Through the precise control of the hydraulic cylinder 32, the up and down movement of the bending head 33 can be ensured to be uniform and stable, thereby improving the accuracy of the bending process and ensuring that the shape and size of the machine casing after bending meet the requirements. Starting the motor 36 and driving the bidirectional lead screw 37 to rotate forward can move the two threaded sleeves 38 and the two fixing plates 310 relative to each other, clamping the two sides of the machine casing. This effectively prevents the machine casing from shifting during the bending process, avoiding inaccurate processing or damage caused by the movement of the machine casing. The fixing plates 310 can ensure the stability of the machine casing during the bending process, reducing the risk of workpiece slippage or damage caused by improper operation or external interference, thereby improving the safety of operation.

[0034] like Figures 1-5As shown, a bending mechanism for processing chassis housing is illustrated in another embodiment of the present invention. The mechanism includes: a dust removal and heat removal component 4 is provided on the top of the operating table 2. The dust removal and heat removal component 4 includes a pressing rod 41. One end of the pressing rod 41 is fixedly connected to the top of the fixing plate 310. An L-shaped rod 42 is fixedly connected to the top of the frame rod 315. A rotating shaft 43 is rotatably connected to the bottom of the L-shaped rod 42. An inclined rod 46 is fixedly connected to the circumferential surface of the rotating shaft 43. A fan blade 44 is fixedly connected to the circumferential surface of the rotating shaft 43. The fan blade 44 generates wind by rotating, which blows air onto the placement table 313 and the bending head 33 to reduce the temperature generated during bending and remove dust from the placement table 313.

[0035] In some examples, the diagonal bar 46 is located on the displacement trajectory of the extrusion bar 41, and several fan blades 44 are arranged in a circumferential array on the circumferential surface of the rotating shaft 43. This design is beneficial for extruding the diagonal bar 46 when the extrusion bar 41 moves.

[0036] A torsion spring 45 is fixedly connected to the circumferential surface of the rotating shaft 43. The end of the torsion spring 45 away from the rotating shaft 43 is fixedly connected to the bottom of the L-shaped rod 42. The design of the torsion spring 45 is conducive to the automatic reset of the rotating shaft 43 when it is not compressed.

[0037] There are two fan blades 44, inclined rods 46, and extrusion rods 41. The fan blades 44 are located on the top of the placement platform 313 and the bending head 33. The bottom of the support leg 1 is fixedly connected with an anti-slip pad 5. The design of the anti-slip pad 5 helps to prevent the entire device from tipping over and sliding.

[0038] For example, such as Figures 1-5As shown, the two fixed plates 310 move relative to each other, which in turn moves the pressing rod 41. The pressing rod 41 follows the fixed plates 310, pressing against the inclined rod 46 during its movement. The inclined rod 46 is located on the trajectory of the pressing rod 41. The pressed inclined rod 46 causes the rotating shaft 43 to rotate along the bottom of the L-shaped rod 42. The rotation of the rotating shaft 43 causes the fan blades 44 to rotate, generating wind. The fan blades 44 are located at the top of the hydraulic cylinder 32, the bending head 33, and the placement platform 313. The wind generated by the rotating fan blades 44 directly blows onto the hydraulic cylinder 32, the bending head 33, and the placement platform 313, affecting the hydraulic cylinder 32 and the bending head 33 during the bending operation. For the placement platform 313, air cooling is used to remove dust and impurities from its top. The hydraulic cylinder 32 and bending head 33 generate a lot of heat during prolonged operation, especially during bending. Excessive heat can affect work efficiency and equipment lifespan. The airflow generated by the fan blades 44 effectively removes heat, lowering the temperature of the hydraulic cylinder 32 and bending head 33, ensuring stable operation, and preventing equipment failure or efficiency loss due to overheating. Dust and impurities often accumulate on the top of the placement platform 313. If this dust enters the equipment, it can adversely affect mechanical operation. Airflow effectively removes these impurities, keeping the working area clean and reducing the probability of malfunctions.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
