Description

Technical Field

[0001] This utility model relates to the field of pipe bending technology, and in particular to a new type of CNC bending equipment that uses electromagnetic power source. Background Technology

[0002] In the sheet metal processing industry, bending equipment, as a core forming device, directly affects product quality and production efficiency. Currently, most mainstream bending equipment on the market uses hydraulic or pneumatic power sources. While these can meet basic production needs, they have gradually revealed numerous technical bottlenecks in practical applications. Specific background technical issues are as follows:

[0003] Existing bending equipment mostly relies on hydraulic drive. The viscosity of hydraulic oil causes a lag in power response (≥0.5s), which can easily lead to asynchronous movement and parameters during multiple bends, resulting in defects in the sheet metal. Furthermore, standby power consumption accounts for over 35%, indicating poor energy efficiency. Although pneumatic drive has a slightly faster response, the driving force is unstable, making it difficult to meet the bending requirements of thick sheet metal and limiting its applicability.

[0004] Based on this, a new type of CNC bending equipment using electromagnetic power source is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a novel CNC bending device that uses electromagnetic power as a power source, thereby solving the problem of poor bending drive effect in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A novel CNC bending device using electromagnetic power source includes a feeding hopper for storing pipe fittings. The bottom of the feeding hopper is provided with an arc-shaped slide that matches the diameter of the pipe fittings. The inside of the feeding hopper is provided with a feeding ramp. The feeding hopper is provided with a pushing assembly for pushing out the pipe fittings. The outlet of the feeding hopper is provided with a bending assembly. The bending assembly includes a fixed plate, a support shaft at the upper end of the fixed plate, a fixed wheel at the upper end of the support shaft, and a movable wheel on the outer side of the fixed wheel. The arc surfaces of the movable wheel and the outer side of the fixed wheel match the outer diameter of the pipe fittings. The movable wheel is connected to a bending drive for driving it to rotate along the outer edge of the fixed wheel.

[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0009] In one alternative embodiment: the bending drive includes a magnetic track in the form of a semi-circular ring. Multiple magnetic push blocks are located at the track's slide position. The magnetic track is supported at both ends by track supports. Magnetic slides are provided on the track's slide. By energizing the magnetic track, the magnetic slides gain forward thrust. This electromagnetic drive method is more precise than traditional pneumatic methods and avoids leakage issues compared to hydraulic methods. The lower end of the movable wheel is rotatably connected to a support shaft. The lower end of the support shaft is connected to a side seat. One end of the side seat is connected to a rotating ring, which is rotatably positioned outside the fixed disc. The other end of the side seat is connected to a connecting shaft. The connecting shaft is rotatably connected to the magnetic slide via a traction rod. When the magnetic slide slides, the traction rod, connecting shaft, and side seat drive the rotating ring to rotate, causing the movable wheel to bend the pipe along the outside of the fixed wheel.

[0010] In one alternative: a second guide block is provided on one side of the fixed wheel to guide the pipe fitting, and a first guide block is provided on one side of the second guide block. The inner cavity formed by the first guide block and the second guide block is matched with the pipe fitting.

[0011] In one alternative embodiment: the feeding assembly includes a feed push column that matches the diameter of the pipe fitting; the lower end of the feeding hopper is provided with a push groove; a feed screw is provided below the feeding hopper; one end of the feed screw is rotatably connected to a support plate; the other end of the feed screw is driven by a feed motor; the feed motor is mounted on a motor frame; a feed sleeve is threaded on the outer side of the feed screw; the feed sleeve is connected to the feed push column through a connecting rod; the connecting rod matches the push groove; and the length of the feed push column is greater than the length of the pipe fitting.

[0012] In one alternative: the outer side of the feeding hopper is provided with a flipping assembly that drives the pipe to flip, so as to adjust the bending direction of the pipe. The flipping assembly includes a mounting ring that rotates at the end of the feeding hopper. The outer side of the mounting ring is provided with a driven gear that meshes with a flipping gear. The flipping gear is driven by a flipping motor, which is fixed on the outer side of the feeding hopper. The mounting ring is provided with a clamping member for holding the pipe.

[0013] In one alternative: the clamping member includes clamping push rods symmetrically arranged on the outside of the mounting ring. The output end of the clamping push rod is provided with a clamping plate. The clamping push rod drives the clamping plate to move closer to the pipe, thereby locking the position of the pipe and providing a basis for flipping.

[0014] In one alternative: the clamping surface of the clamping plate is provided with an anti-slip layer.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model is designed to meet existing needs and constructs a magnetically driven bending method. The accuracy of this driving method comes from the linear relationship between electromagnetic field strength and current. The precise control of the sliding seat displacement can be achieved by precisely controlling the current. At the same time, since there is no mechanical contact transmission and fluid medium, the pneumatic pressure fluctuation error and hydraulic leakage problem are avoided in principle.

[0017] 2. This utility model makes feeding more convenient, allowing the pipe fittings to be bent continuously, thus ensuring feeding efficiency.

[0018] 3. This utility model is designed to meet existing needs and can flip the pipe fitting, thereby allowing the pipe fitting to be bent at multiple angles and improving the processing range. Attached Figure Description

[0028] 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.

[0029] Example 1

[0030] like Figures 1-3 As shown, this utility model embodiment provides a novel CNC bending device using electromagnetic power as a power source, including a feeding hopper 100 for storing pipe fittings 300. The feeding hopper 100 has a feeding support 102 at its bottom. An arc-shaped slide matching the diameter of the pipe fittings 300 is provided at the bottom of the feeding hopper 100. A feeding inclined surface 101 is provided inside the feeding hopper 100, allowing the pipe fittings 300 to be arranged sequentially on the inner wall of the feeding hopper 100. The feeding hopper 100 also has a mechanism for ejecting the pipe fittings 300. The feeding assembly includes a bending assembly at the outlet of the feeding hopper 100. The bending assembly includes a fixed disk 409, a support shaft 407 at the upper end of the fixed disk 409, a fixed wheel 403 at the upper end of the support shaft 407, and a movable wheel 402 on the outer side of the fixed wheel 403. The arc surfaces of the movable wheel 402 and the outer side of the fixed wheel 403 match the outer diameter of the pipe fitting 300. The movable wheel 402 is connected to a bending drive for driving it to rotate along the outer edge of the fixed wheel 403.

[0031] The bending drive includes a magnetic track 406, which has a semi-circular structure. Multiple magnetic push blocks 405 are located at the slide positions of the magnetic track 406. Both ends of the magnetic track 406 are supported by track supports 408. Magnetic slide blocks 404 are provided on the upper slide of the magnetic track 406. By energizing the magnetic track 406, the magnetic slide blocks 404 receive forward thrust. This electromagnetic drive method is more precise than traditional pneumatic methods and avoids leakage problems compared to hydraulic methods. The lower end of the movable wheel 402 is connected to the support shaft 41. 4. The lower end of the support shaft 414 is connected to the side seat 411. One end of the side seat 411 is connected to the rotating ring 410. The rotating ring 410 is rotatably disposed on the outside of the fixed disk 409. The other end of the side seat 411 is connected to the connecting shaft 413. The connecting shaft 413 is rotatably connected to the magnetic slide 404 through the traction side rod 412. When the magnetic slide 404 slides, the traction side rod 412, the connecting shaft 413 and the side seat 411 will drive the rotating ring 410 to rotate, thereby causing the movable wheel 402 to bend the pipe 300 along the outside of the fixed wheel 403.

[0032] The working principle of magnetic drive is based on the interaction between electromagnetic induction and magnetic fields, and can be divided into the following core processes:

[0033] Electromagnetic field generation: When the magnetic track 406 is energized, the track coil will generate an electromagnetic field with a specific direction and intensity. Its magnetic field distribution matches the semi-circular structure of the track and the layout of the magnetic push block 405, forming a regularly changing magnetic field environment.

[0034] Electromagnetic force drive: The magnetic slide 404 has a built-in permanent magnet or magnetizable material, which will be subjected to Lorentz force or magnetic attraction / repulsion under the action of the track's electromagnetic field. By controlling the direction and magnitude of the track current, the magnetic field strength and direction can be precisely adjusted, so that the magnetic slide 404 obtains a driving force along the track tangent, realizing smooth sliding along the semi-circular track.

[0035] Force transmission and transformation: The sliding of the magnetic slide 404 is transformed into the circular motion of the rotating ring 410 through the transmission components such as the rotating shaft traction side rod 412 and the connecting rod connecting shaft 413, which ultimately drives the movable wheel 402 to apply bending force to the pipe.

[0036] The precision of this driving method stems from the linear relationship between electromagnetic field strength and current. By precisely controlling the current, the displacement of the sliding seat can be accurately controlled. At the same time, since there is no mechanical contact transmission or fluid medium, it avoids the air pressure fluctuation error of pneumatics and the leakage problem of hydraulics in principle.

[0037] The fixed wheel 403 is provided with a second guide block 400 on one side to guide the pipe fitting 300, and a first guide block 401 is provided on one side of the second guide block 400. The inner cavity formed by the first guide block 401 and the second guide block 400 is matched with the pipe fitting 300.

[0038] The feeding assembly includes a feed push column 200 that matches the diameter of the pipe fitting 300. The lower end of the feeding hopper 100 is provided with a push groove 205. A feed screw 203 is located below the feeding hopper 100. One end of the feed screw 203 is rotatably connected to a support plate, and the other end of the feed screw 203 is driven by a feed motor 201. The feed motor 201 is mounted on a motor frame 202. A feed sleeve 204 is threaded onto the outer side of the feed screw 203. The feed sleeve 204 is connected to the feed push column 200 via a connecting rod, which matches the push groove 205. The length of the feed push column 200 is greater than the length of the pipe 300. Driven by the feed motor 201, the feed screw 203 and the feed sleeve 204 rotate relative to each other. Under the action of the thread, the feed sleeve 204 drives the feed push column 200 to slide along the inner wall of the hopper 100, thereby pushing the pipe 300 in the hopper 100 to the bending position.

[0039] Working principle: In use, multiple pipe fittings 300 are placed in the feeding hopper 100. The bottommost pipe fitting 300 is pushed out by the pushing assembly. The pipe fitting 300 passes between the second guide block 400 and the first guide block 401, and then passes through the movable wheel 402 and the fixed wheel 403. By energizing the magnetic track 406, the magnetic slide 404 obtains forward thrust. When the magnetic slide 404 slides, the traction side rod 412, the connecting shaft 413 and the side seat 411 drive the rotating ring 410 to rotate, thereby causing the movable wheel 402 to bend the pipe fitting 300 along the outside of the fixed wheel 403.

[0040] Example 2

[0041] like Figure 4 As shown, unlike Embodiment 1, the outer side of the feeding hopper 100 is provided with a flipping assembly for rotating the pipe 300, so as to adjust the bending direction of the pipe 300. The flipping assembly includes a mounting ring 504 rotating at the end of the feeding hopper 100. A driven gear 502 is provided on the outer side of the mounting ring 504. The driven gear 502 meshes with a flipping gear 501. The flipping gear 501 is driven by a flipping motor 500, which is fixed on the outer side of the feeding hopper 100. The mounting ring 504 is provided with a clamping member for clamping the pipe 300. The position of the pipe 300 is locked by the clamping member. Then, the flipping motor 500 drives the flipping gear 501 to rotate. The flipping gear 501 matches the driven gear 502 and drives the mounting ring 504 to rotate, thereby driving the pipe 300 to flip.

[0042] The clamping component includes clamping push rods 505 symmetrically arranged on the outside of the mounting ring 504. The output end of the clamping push rod 505 is provided with a clamping plate 503. The clamping push rod 505 drives the clamping plate 503 to move closer to the pipe 300, thereby locking the position of the pipe 300 and providing a basis for flipping. The clamping surface of the clamping plate 503 is provided with an anti-slip layer.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
