In order to improve people's physical fitness and ensure good health, fitness equipment is becoming more and more popular. During the manufacturing process of fitness equipment, it is often necessary to bend the tube body. After the raw material is bent, it is convenient for the later processing and welding needs. In order to facilitate the user to hold and fix it to prevent injury, fitness equipment has a large number of bent tubes, which is convenient for grasping and also increases the friction with the hand, enhancing personal safety during fitness. Bending during the processing of fitness equipment is a very important process.
[0003] In order to facilitate the bending of fitness equipment during processing, it is usually necessary to cut the raw materials so as to bend the required curved tubes. The commonly used methods for bending and cutting in the prior art are laser cutting and punching. The laser cutting equipment requires large power, the cutting equipment is expensive, and the cost of use is relatively high. Punching can usually only cut a 90-degree incision to achieve a 90-degree bend. It cannot perform multiple cutting at multiple angles as required, and cannot achieve arc-shaped bending. In addition, the application field of punching is limited. It cannot punch thick tubes with high hardness. When punching thin-walled tubes, it is easy to cause the pipes to be squeezed, deformed, and collapsed. The punching quality is relatively low, which affects the subsequent processing and use.

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings. Figures 1 to 7 As shown, the present invention provides a bending and cutting device for processing fitness equipment, including a base plate 1, a feeding assembly 2 is arranged at the left end of the base plate 1, a fixing assembly 3 is arranged at the right end of the base plate 1, and the fixing assembly 3 includes a support plate 31, an upper fixing assembly 32, a middle fixing assembly 33 and a lower fixing assembly 34 are arranged on the support plate 31, and the middle fixing assembly 33 is arranged between the upper fixing assembly 32 and the lower fixing assembly 34. The upper fixing assembly 32, the middle fixing assembly 33 and the lower fixing assembly 34 have the same structure, and the upper fixing assembly 32 and the lower fixing assembly 34 slide up and down with the support plate 31 through two slider guide assemblies 39. Dynamic connection, the right ends of the upper fixed component 32 and the lower fixed component 34 are fixedly connected with drive blocks 38, and springs 381 are fixedly connected between the drive blocks 38. The right ends of the drive blocks 38 are symmetrically provided with inclined surfaces. The right ends of the drive blocks 38 are slidably connected to the drive card plate 36, and the drive card plate 36 is provided with a trapezoidal groove. The inclined surface of the trapezoidal groove is in sliding contact with the inclined surface of the drive block 38. The right end of the drive card plate 36 is fixedly connected to the telescopic end of the cylinder 37, and the cylinder 37 is fixedly connected to the support plate 31. The upper and lower ends of the drive card plate 36 are slidably connected with positioning bars 35, and the positioning bars 35 are fixedly set on the support plate 31.
[0036] During operation, the steel pipe 11 is sleeved on the middle fixing component 33. The steel pipe 11 is fixedly connected to the feeding component 2. The feeding component 2 drives the steel pipe 11 to slide on the middle fixing component 33. When the steel pipe 11 slides to the designated position, the telescopic end of the cylinder 37 extends leftward to drive the driving clamping plate 36 to move leftward. The driving clamping plate 36 drives the driving blocks 38 to approach each other, thereby driving the upper fixing component 32 and the lower fixing component 34 to approach each other in the vertical direction to squeeze and fix the steel pipe 11. Then, the cutting disc cuts the steel pipe 11, and a cut 111 is cut out on the steel pipe 11 as required. The cutting disc is a prior art and belongs to a cutting blade with multiple degrees of freedom, which can move with multiple degrees of freedom as required to adjust the cutting angle and cutting path. Through the squeezing and fixing of the upper fixing component 32 and the lower fixing component 34, the clamping and fixing of the steel pipe 11 can be realized. The shape and size of the middle fixing component 33 are the same as those of the steel pipe. The middle fixing component 33 can fix and support the steel pipe 11 to prevent the steel pipe from deforming under force during cutting. Due to the support of the middle fixing component 33 and the squeezing of the upper fixing component 32 and the lower fixing component 34, a punching cutter can also be used for rapid punching during the cutting of the steel pipe 11, and the steel pipe 11 will not generate deformations such as collapse during the punching process, improving work efficiency.
[0037] Further, as Figure 5-Figure 7 shown, the upper fixing component 32 includes a rectangular frame 321. The rectangular frame 321 is a hollow rectangular column. A groove is provided in the middle of the rectangular frame 321. The rectangular frame 321 is integrally in an inverted "C" shape.

Two meshing gears 326 are rotatably connected in the rectangular through hole of the slide plate 322. The left gear 326 is fixedly connected to a left swing plate 323, and the right gear 326 is fixedly connected to a right swing plate 327. The upper and lower surfaces of the left swing plate 323 and the right swing plate 327 are coplanar with the upper and lower surfaces of the rectangular frame 321. The ends of the left swing plate 323 and the right swing plate 327 far from the gears 326 are slidably connected to a telescopic block 324. The telescopic block 324 includes a cylinder 3241. Horizontal bars 3242 are fixedly provided at the upper and lower ends of the cylinder 3241 and are arranged in parallel. The horizontal bars 3242 are slidably connected to the upper and lower surfaces of the left swing plate 323 and the right swing plate 327. A slider 325 is rotatably sleeved on the cylinder 3241. A through hole 3251 is provided vertically on the slider 325, and the through hole 3251 is sleeved outside the cylinder 3241. The slider 325 is slidably connected to the front side of the groove of the rectangular frame 321.
[0038] Furthermore, a waist-shaped groove 3271 is horizontally provided on the side of the right swing plate 327 away from the left swing plate 323, and a sliding column 3283 is slidably connected in the waist-shaped groove 3271. The sliding column 3283 is provided on the adjusting bolt 328, and the adjusting bolt 328 is threadedly connected to the side wall of the rectangular frame 321. A locking nut 329 is threadedly connected on the adjusting bolt 328. The end of the adjusting bolt 328 away from the locking nut 329 is rotatably connected to a connecting block 3281, and the end of the connecting block 3281 close to the locking nut 329 is provided with a rotating block 3282, and the rotating block 3282 is rotatably connected to the end of the adjusting bolt 328, and the sliding column 3283 is provided at one end of the connecting block 3281 away from the rotating block 3282.
[0039] Furthermore, the slide plates 322 of the upper fixing assembly 32 and the lower fixing assembly 34 are rotatably connected to one side away from the right swing plate 327 with two adjusting bolts 24, the two adjusting bolts 24 are horizontally arranged left and right, the adjusting bolts 24 are threadedly connected to the back side of the rectangular frame 321, and the two adjusting bolts 24 are both threadedly connected with locking nuts 242.
[0040] During operation, the adjusting bolt 328 is threadedly connected to the rectangular frame 321. The adjusting bolt 328 is moved relative to the rectangular frame 321 by rotating the adjusting bolt 328, and the adjusting bolt 328 pushes the right swing plate 327 to swing. The swing of the right swing plate 327 drives the right gear 326 to rotate. The right gear 326 engages to drive the left gear 326 to rotate. The left gear 326 drives the left swing plate 323 to swing, thereby realizing the angle adjustment between the left swing plate 323 and the right swing plate 327. After the adjustment is completed, the adjusting bolt 328 is locked relative to the rectangular frame 321 by the locking nut 329. When the left swing plate 323 and the right swing plate 327 swing, the telescopic block 324 is driven to extend and retract at the ends of the left swing plate 323 and the right swing plate 327, and the telescopic block 324 drives the slider 325 to slide horizontally, and the slider 325 supports the telescopic block 324 and the left swing plate 323 and the right swing plate 327, so that after the angle adjustment of the left swing plate 323 and the right swing plate 327 is completed, the left swing plate 323, the right swing plate 327 and the telescopic block 324 can support the inside of the steel pipe 11.
[0041] The adjusting bolt 24 is threadedly connected to the rectangular frame 321. The adjusting bolt 24 is rotated to move the adjusting bolt 24 relative to the rectangular frame 321, and the adjusting bolt 24 drives the slide plate 322 to move forward and backward. The movement of the slide plate 322 drives the ends of the left swing plate 323 and the right swing plate 327 that are close to each other to move forward and backward to adapt to the depth of the incision 111 of the steel pipe 11, so that the V-shaped space formed by the left swing plate 323, the right swing plate 327 and the telescopic block 324 has the same shape as the incision of the steel pipe 11, which can provide precise support for the steel pipe 11 when cutting to prevent the steel pipe from being squeezed, collapsed and deformed.
[0042] Further, such as Figure 8-Figure 11 The middle fixed component 33 includes a rectangular frame 331, and the side of the rectangular frame 331 away from the cylinder 37 is fixedly connected to a guide tube 333. A driving bar 334 is slidably connected inside the guide tube 333. The driving bar 334 is fixedly connected to a slide plate 332 in the rectangular frame 331. The guide tube 333 is a hollow tube with a rectangular cross-section, and the guide tube 333 is fixedly connected to the feed component 2.
[0043] Furthermore, the feed assembly 2 includes a bracket 21, the bracket 21 is fixedly connected to the base plate 1, the guide tube 333 passes through the bracket 21 and is fixed to the fixed block 211 on the side of the bracket 21, the side of the guide tube 333 close to the fixed block 211 is threadedly connected with an adjusting bolt three 335, the end of the adjusting bolt three 335 is rotatably connected to the driving bar 334, and the adjusting bolt three 335 is threadedly connected with a locking nut three 336.
[0044] During operation, by rotating the adjusting bolt three 335, the adjusting bolt three 335 is moved relative to the guide tube 333, thereby pushing the driving bar 334 to move, and the driving bar 334 pushes the slide plate two 332 to move. When the slide plate two 332 moves into place, the locking nut three 336 locks the adjusting bolt three 335 on the guide tube 333, thereby realizing the position adjustment and positioning of the slide plate two 332.
[0045] Furthermore, the side of the guide tube 333 is slidably connected with a half screw rod 23, the surface of the half screw rod 23 is provided with a plane penetrating the half screw rod 23, the guide tube 333 is relatively slidably connected with the plane, the half screw rod 23 is externally threadedly connected with a screw nut 24, and the screw nut 24 is rotatably connected to the side of the bracket 21.
[0046] (The half screw rod 23 is a screw rod with a missing cross-section rather than a complete circle. The missing part can be set according to actual conditions. The missing part can accommodate the guide tube 333, so that the guide tube 333 does not affect the normal threaded connection between the half screw rod 23 and the screw nut 24). A large gear 25 is fixedly connected to the outside of the screw nut 24, and a small gear 26 is meshedly connected to the side of the large gear 25. The small gear 26 is fixed to the output shaft of the servo motor 27, and the servo motor 27 is fixedly connected to the bracket 21.

[0048] During the working process, firstly, the position of the slide plate 322 of the fixing assembly 3 is adjusted according to the cutting angle and cutting position of the steel pipe 11, and at the same time, the angle between the left swing plate 323 and the right swing plate 327 is adjusted so that the space between the left swing plate 323 and the right swing plate 327 is the same shape as the incision 111 of the steel pipe 11.
[0049] Then, the steel pipe 11 is sleeved from the right end onto the outside of the middle fixing assembly 33 and the guide tube 333, so that the end of the steel pipe 11 enters the connecting frame 231 and abuts against the end of the half screw rod 23, and the fixing bolt 232 is rotated to squeeze the steel pipe to achieve relative fixation between the steel pipe 11 and the half screw rod 23.
[0050] Then the servo motor 27 is started, and the servo motor 27 drives the small gear 26 and the large gear 25 to rotate, and the large gear 25 drives the screw nut 24 to rotate, and the screw nut 24 drives the half screw 23 and the steel pipe 11 to move. When the steel pipe moves into place, the cylinder 37 drives the upper fixing assembly 32 and the lower fixing assembly 34 to move toward the middle fixing assembly 33 to achieve fixed support for the steel pipe 11.
[0051] Finally, the steel pipe 11 is cut by a punching knife or a cutting disc. When multiple cuts 111 need to be cut, the above process is repeated until appropriate cuts 111 are cut on the steel pipe 11, and the steel pipe is removed to complete the pipe bending operation.
[0052] The beneficial effects of the present invention are as follows: the present invention fixes and supports the steel pipe 11 by setting an upper fixing component 32, a middle fixing component 33 and a lower fixing component 34, so that the inner and outer edges of the cutout 111 of the steel pipe 11 can be supported to prevent the steel pipe 11 from being squeezed, collapsed and deformed, and the cutting effect is good, and a punching knife or a cutting disc can be used to save production costs.
[0053] Secondly, the present invention can adjust the position of the slide plate 322 and the angle between the left swing plate 323 and the right swing plate 327, so that the space between the left swing plate 323 and the right swing plate 327 has the same structure as the incision 111 of the steel pipe 11, can adapt to incisions 111 of different shapes, and has a wide range of applications.
