Description

Technical Field

[0001] This invention relates to the field of wire drawing machine technology, specifically to a wire drawing machine for the surface of steel pipes used in new energy vehicles to prevent slippage during installation. Background Technology

[0002] A wire drawing machine is a type of mechanical equipment mainly used to process thicker wires into wires that meet specific standards through drawing. A surface wire drawing machine for steel pipes used in new energy vehicles is specifically designed for wire drawing of steel pipes for new energy vehicles. These steel pipes are generally made of high-strength, lightweight special alloy materials. Wire drawing improves the appearance and texture of the steel pipes, enhancing the smoothness and quality of the surface. This is crucial for meeting the aesthetic requirements and product quality standards of new energy vehicles.

[0003] In the existing technology, when drawing steel pipes for new energy vehicles, the steel pipes are first placed on an inclined guide support wheel. Then, the steel pipes on the guide support wheel are drawn by driving the drawing wheel. The drawing wheel rotates and contacts the surface of the steel pipe to draw the steel pipe. At the same time, the rotating drawing wheel drives the steel pipe to rotate through friction. The rotation of the steel pipe drives the inclined guide support wheel to rotate, so that the steel pipe is drawn and fed through the rotating support wheel at the same time.

[0004] Currently, when the steel pipe is placed on the guide support wheel and drawn by the rotation of the drawing wheel, there is no other limiting structure to limit the steel pipe. This may cause the steel pipe to jump and slip during the drawing process, resulting in unstable relative movement and reduced drawing effect. This may lead to unevenness, ripples, scratches or other poor quality problems on the surface of the steel pipe.

[0005] Meanwhile, due to long-term use of the equipment, internal parts such as gears may wear out, or operators may make mistakes when setting parameters, which may cause the wire drawing wheel to rotate too fast. The excessively fast rotation speed of the wire drawing wheel will increase the generation of frictional heat, causing the surface temperature of the steel pipe to rise. This may affect the physical properties and mechanical strength of the steel pipe, and even cause the steel pipe to deform or reduce its quality, affecting the appearance quality and smoothness of the steel pipe.

[0006] Therefore, a surface wire drawing machine for new energy vehicle steel pipes was proposed to prevent slippage during installation, in order to solve the above problems. Summary of the Invention

[0007] In view of this, the technical problem to be solved by the present invention is to propose a surface wire drawing machine for new energy vehicle steel pipes that prevents slippage during installation, so as to solve the problem that vibration or excessive feeding speed may occur during steel pipe wire drawing in the prior art, which affects the wire drawing quality.

A latching hole is provided on the side of the spring latch near the fixed rod, and the latching hole is adapted to the latching block.

[0012] Preferably, a fixing block is fixedly connected to the upper surface of the base, and a U-shaped rod is slidably connected between the inner walls of the fixing block. The upper end of the U-shaped rod passes through the upper surface of the fixing block, and an arc-shaped pressure plate is fixedly connected to the upper end of the U-shaped rod. A return spring is symmetrically sleeved on the upper end of the U-shaped rod, and the return spring is located between the arc-shaped pressure plate and the fixing block. Ball bearings are equidistantly rotatably connected to the lower surface of the arc-shaped pressure plate.

[0013] Preferably, the bottom of the U-shaped rod is symmetrically and rotatably connected to a connecting rod, the upper surface of the base is slidably connected to an L-shaped slide rod, the L-shaped slide rod is rotatably connected to the connecting rod, the inner wall of the outer shell is symmetrically and slidably connected to sliding columns, a support roller is rotatably connected between the sliding columns, a push rod is fixedly connected to the outer surface of the sliding column, and the bottom of the push rod is fixedly connected to the left end of the L-shaped slide rod.

[0014] Preferably, the detection and protection mechanism includes a U-shaped slide rail, which is fixedly connected to the upper surface of the base. A sliding seat is slidably connected between the inner walls of the U-shaped slide rail. A drive motor is fixedly connected to the upper surface of the sliding seat. A wire drawing wheel is fixedly connected to the output end of the drive motor. A drive gear is fixedly connected to the front shaft end of the wire drawing wheel.

[0015] Preferably, an L-shaped connecting rod is fixedly connected to the bottom of the front end of the drive motor, and a driven gear is rotatably connected to the upper end of the L-shaped connecting rod near the drive motor. The driven gear meshes with the driving gear. A rotating disk is rotatably connected to the side of the L-shaped connecting rod away from the drive motor. The rotating disk passes through the L-shaped connecting rod and is fixedly connected to the driven gear.

[0016] Preferably, the outer surface of the rotating disk has an inner cavity, and a centrifugal block is slidably connected to the inner cavity of the rotating disk. The centrifugal block passes through the outer surface of the rotating disk, and a tension spring is fixedly connected between the centrifugal block and the rotating disk.

[0019] Compared with the prior art, the present invention provides a surface wire drawing machine for steel pipes in new energy vehicles that prevents slippage during installation, and has the following beneficial effects:

[0020] 1. When the rotation speed is too fast, the arc surface of the pusher block pushes the arc surface of the clamp rod as the sliding rod moves, causing the pusher rod to slide away from the arc block. This prevents the wire drawing wheel from rotating too fast, as excessive rotation speed will increase the generation of frictional heat, causing the surface temperature of the steel pipe to rise, affecting the physical properties and mechanical strength of the steel pipe, and even causing the steel pipe to deform or reduce its quality. At the same time, the alarm can enable the staff to discover and deal with this situation as soon as possible, ensuring the appearance quality and smoothness of the steel pipe.

[0021] 2. By using the ball bearings at the bottom of the arc-shaped pressure plate, the proximity of the support rollers, and the support of the bottom guide wheels, the steel pipe is limited from three directions. This makes the steel pipe more stable when placed between the guide wheels, preventing the steel pipe from jumping or slipping during subsequent wire drawing. This ensures the stability of the steel truss during the wire drawing process, avoiding fluctuations or unevenness, and improving the quality of steel pipe wire drawing. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0036] Embodiments of the present invention

[0037] Please refer to Figures 1 to 5 As shown:

[0038] To address the problems mentioned in the technical solutions, this application provides a surface drawing machine for new energy vehicle steel pipes that prevents slippage during installation. The machine includes a base 1, with an outer shell 11 fixedly connected to the upper surface of the base 1. Guide wheels 2 are fixedly connected to the upper surface of the base 1, with at least eight guide wheels 2. The surface drawing machine for new energy vehicle steel pipes that prevents slippage during installation includes a limiting protection mechanism and a detection protection mechanism. The limiting protection mechanism is located in front of the detection protection mechanism. The limiting protection mechanism is used to limit the clamping of the steel pipe, and the detection protection mechanism is used to prevent the steel pipe from feeding too quickly.

[0039] The limiting and protective mechanism includes a fixed rod 301, which is fixedly connected to the upper surface of the base 1. A support rod 302 is fixedly connected to the upper surface of the base 1. A rotating rod 303 is rotatably connected to the top of the support rod 302. A spring catch rod 304 is fixedly connected to one end of the rotating rod 303 near the fixed rod 301. A catch block is fixedly connected to one end of the spring catch rod 304 near the fixed rod 301. A catch hole 305 is provided on the side of the spring catch rod 304 near the fixed rod 301, and the catch hole 305 is adapted to the catch block. A fixed block 306 is fixedly connected to the upper surface of the base 1. A U-shaped rod 309 is slidably connected between the inner walls of the fixed block 306. The upper end of the U-shaped rod 309 passes through the upper surface of the fixed block 306. An arc-shaped pressure plate 308 is fixedly connected to the upper end of the U-shaped rod 309. A return spring 307 is symmetrically sleeved on the upper end of the U-shaped rod 309. The return spring 307 is located between the arc-shaped pressure plate 308 and the fixed block 306. Ball bearings are equidistantly rotatably connected to the lower surface of the arc-shaped pressure plate 308. A connecting rod 310 is symmetrically rotatably connected to the bottom of the U-shaped rod 309. An L-shaped slide rod 314 is slidably connected to the upper surface of the base 1. The L-shaped slide rod 314 is rotatably connected to the connecting rod 310. Sliding columns 312 are symmetrically slidably connected to the inner wall of the outer shell 11. A support roller 313 is rotatably connected between the sliding columns 312. A push rod 311 is fixedly connected to the outer surface of the sliding column 312. The bottom of the push rod 311 is fixedly connected to the left end of the L-shaped slide rod 314.

[0040] Among them, the rotating rod 303 at the right end of the support rod 302 is the power arm, and the rotating rod 303 at the left end of the support rod 302 is the resistance arm. The power arm of the rotating rod 303 is greater than the resistance arm, which makes it easier to pull the rotating rod 303 at the right end of the support rod 302 and press down the arc-shaped pressure plate 308.

[0041] In the prior art, when the steel pipe is placed on the guide support wheel and drawn by the rotation of the drawing wheel 404, there is no other limiting structure to limit the steel pipe. This can lead to the steel pipe jumping and slipping during the drawing process, resulting in unstable relative movement and reduced drawing effect. This may cause unevenness, ripples, scratches, or other quality problems on the surface of the steel pipe. Compared with the prior art, the implementation of this embodiment limits the steel pipe from three directions through the ball bearings at the bottom of the arc-shaped pressure plate 308, the proximity of the support roller 313, and the support of the bottom guide wheel 2. This makes the steel pipe more stable when placed between the guide wheels 2, preventing the steel pipe from jumping and slipping during the subsequent drawing process. This stabilizes the steel truss during the steel pipe drawing process, avoids fluctuations or unevenness during drawing, and improves the quality of steel pipe drawing.

[0042] Further examples: Please refer to Figures 6 to 8 As shown:

[0043] The detection and protection mechanism includes a U-shaped slide rail 401, which is fixedly connected to the upper surface of the base 1. A sliding seat 402 is slidably connected between the inner walls of the U-shaped slide rail 401. A drive motor 403 is fixedly connected to the upper surface of the sliding seat 402. A wire drawing wheel 404 is fixedly connected to the output end of the drive motor 403. A drive gear 405 is fixedly connected to the front shaft end of the wire drawing wheel 404. An L-shaped connecting rod 406 is fixedly connected to the bottom of the front end of the drive motor 403. A driven gear 407 is rotatably connected to the upper end of the L-shaped connecting rod 406 near the drive motor 403. The driven gear 407 meshes with the drive gear 405. A rotating disk 408 is rotatably connected to the side of the L-shaped connecting rod 406 away from the drive motor 403. The rotating disk 408 passes through the L-shaped connecting rod 406 and is fixedly connected to the driven gear 407. An inner cavity is formed on the outer surface of the rotating disk 408. A centrifugal block 4081 is slidably connected to the inner cavity of the disc 408. The centrifugal block 4081 passes through the outer surface of the rotating disc 408. A tension spring 409 is fixedly connected between the centrifugal block 4081 and the rotating disc 408. A push rod 410 is slidably connected to the upper surface of the base 1. An electrical contact 411 is fixedly connected to the right side of the push rod 410 and the upper surface of the base 1. A limit block 414 is slidably connected to the front side of the U-shaped slide rail 401. The limit block 414 is fixedly connected to the sliding seat 402. A compression spring rod 415 is symmetrically fixedly connected between the sliding seat 402 and the U-shaped slide rail 401. An arc-shaped block 413 is fixedly connected to the side of the push rod 410 near the U-shaped slide rail 401. The arc-shaped block 413 and the push rod 412 are both set to be arc-shaped on the side closest to each other. An alarm is fixedly connected to the upper surface of the base 1. The electrical contacts 411 are electrically connected to control the opening and closing of the alarm.

[0044] Wherein: the diameter of the driving gear 405 is smaller than the diameter of the driven gear 407. When the driving gear 405 rotates one revolution, the driven gear 407 rotates less than one revolution. When the wire drawing wheel 404 rotates at normal speed to complete the wire drawing work, the driven gear 407 will drive the rotating disk 408 to rotate more slowly, so that the centrifugal block 4081 is subjected to less centrifugal force and the tension spring 409 has a smaller tension distance, so that the centrifugal block 4081 cannot approach the top of the push slide rod 410 during the rotation process.

[0045] In existing technologies, due to long-term use of equipment, internal parts such as gears may experience wear, or operators may make mistakes when setting parameters, which could cause the wire drawing wheel 404 to rotate too fast. Excessive rotation speed of the wire drawing wheel 404 increases frictional heat, leading to an increase in the surface temperature of the steel pipe. This can affect the physical properties and mechanical strength of the steel pipe, and even cause deformation or quality reduction, impacting the appearance and smoothness of the steel pipe. Compared to existing technologies, this embodiment prevents excessively fast rotation of the wire drawing wheel 404 from increasing frictional heat, raising the surface temperature of the steel pipe, affecting its physical properties and mechanical strength, and even causing deformation or quality reduction. Simultaneously, the alarm system allows operators to detect and address this situation immediately, ensuring the appearance and smoothness of the steel pipe.

[0046] The working principle of all the content in the above embodiments is as follows:

[0047] In the initial state: the steel pipe is placed on the upper surface of multiple guide wheels 2. When the reset spring 307 is in the normal state, the U-shaped rod 309 is located at the upper end of the groove of the fixed block 306. The bottom ball of the arc-shaped pressure plate 308 and the support roller 313 are not in contact with the steel pipe. The spring clamp rod 304 is in the compressed state. The clamping block and the clamping hole 305 at one end of the spring clamp rod 304 are not engaged. At the same time, the tension spring 409 is in the normal state. The centrifugal block 4081 is located in the groove of the rotating disk 408. The limiting plug 414 and the sliding seat 402 are located at the right end of the U-shaped slide rail 401, so that the wire drawing wheel 404 is not in contact with the steel pipe. At the same time, the limiting plug 414 is away from the arc-shaped block 413 and is not engaged with the U-shaped slide rail 401.

[0048] The following is the working process of the limit protection mechanism for clamping and limiting the steel pipe:

[0049] Before the drive motor 403 drives the drawing wheel 404 to draw the steel pipe, the operator can first manually pull the end of the rotating rod 303 near the fixed rod 301 upwards, causing the right end of the rotating rod 303 to rotate upwards and the left end to rotate downwards. When the left end of the rotating rod 303 rotates downwards, it presses down on the arc-shaped pressure plate 308, causing the arc-shaped pressure plate 308 and the U-shaped rod 309 to move downwards simultaneously. The return spring 307 enters a compressed state, and when the lower end of the U-shaped rod 309 slides downwards, the U-shaped rod 309 pushes the connecting rod 310 to swing, causing... The connecting rod 310, at the end furthest from the U-shaped rod 309, pushes the L-shaped slide rod 314 to slide to the right. This, in turn, causes the push rod 311 and sliding column 312 to slide closer to the steel pipe. Finally, the sliding column 312 causes the support roller 313 to contact the steel pipe. The arc-shaped pressure plate 308 moves downwards, causing the bottom ball bearing of the arc-shaped pressure plate 308 to contact the steel pipe, thus completing the clamping and limiting of the steel pipe. At this time, the spring clamp rod 304 causes the clamping block to approach the clamping hole 305. Under the elastic force of the spring clamp rod 304, the spring clamp rod 304... 04 The locking block at one end engages with the locking hole 305, thereby fixing the rotating rod 303. This fixing of the rotating rod 303 then fixes the arc-shaped pressure plate 308 and the support roller 313. Furthermore, through the arrangement of the support rod 302 and the rotating rod 303, when the rotating rod 303 is pulled to press down the arc-shaped pressure plate 308, according to the lever principle, since the rotating rod 303 at the right end of the support rod 302 is the effort arm and the rotating rod 303 at the left end of the support rod 302 is the resistance arm, the effort arm of the rotating rod 303 is greater than the resistance arm. Therefore, when pulling... When the rotating rod 303 at the right end of the moving support rod 302 presses down on the arc-shaped pressure plate 308, it will be more labor-saving. At the same time, the ball bearings at the bottom of the arc-shaped pressure plate 308, the approach of the support roller 313, and the support of the bottom guide wheel 2 limit the steel pipe from three directions, making the steel pipe more stable when placed between the guide wheels 2. This prevents the steel pipe from jumping and slipping during the subsequent wire drawing process, making the steel truss stable during the wire drawing process and avoiding fluctuations or unevenness during wire drawing, thus improving the quality of steel pipe wire drawing.

[0050] Please refer to the above work process. Figures 1 to 5 .

[0051] The following is the working process of the detection and protection mechanism to prevent the steel pipe from feeding too fast:

[0052] Furthermore, after the steel pipe is placed, the worker can manually push the sliding seat 402 to slide towards the steel pipe between the U-shaped slide rails 401. When the wire drawing wheel 404 contacts the steel pipe, the sliding seat 402 stops sliding. At this time, the sliding seat 402 approaches and squeezes the compression spring rod 415, causing the compression spring rod 415 to enter the compressed state. Then, it pushes the push lever 412 to slide towards the arc-shaped block 413 and contact the side of the arc-shaped block 413. At the same time, the limiting insert 414 is inserted into the slot of the U-shaped slide rail 401, completing the fixation of the sliding seat 402. Then, the drive motor 403 is started, which drives the wire drawing wheel 404 to rotate and perform wire drawing on the steel pipe. When the drawing wheel 404 rotates, since the driving gear 405 and the driven gear 407 are meshed, and the driven gear 407 is fixed to the rotating disk 408, the driving gear 405 and the driven gear 407 will simultaneously drive the rotating disk 408 to rotate. Because the drawing wheel 404 rotates at a normal speed, and the diameter of the driving gear 405 is smaller than the diameter of the driven gear 407, when the driving gear 405 rotates one revolution, the driven gear 407 rotates less than one revolution. Therefore, when the drawing wheel 404 completes the drawing work at its normal speed, the driven gear 407 will drive the rotating disk 408 to rotate more slowly, resulting in a smaller centrifugal force on the centrifugal block 4081 and a smaller extension distance for the tension spring 409. The smaller size of the centrifugal block 4081 prevents it from approaching the top of the push rod 410 during rotation. Furthermore, when the drawing wheel 404 rotates at a higher speed, the driving gear 405 drives the driven gear 407 and the rotating disk 408 to rotate at a higher speed, resulting in a larger centrifugal force on the centrifugal block 4081, a larger stretching distance for the tension spring 409, and a larger sliding distance for the centrifugal block 4081. Consequently, when the centrifugal block 4081 rotates, it approaches and pushes the push rod 410 away from the rotating disk 408, causing the two electrical contacts 411 to come into contact and activate the alarm signal. Simultaneously, as the push rod 410 moves, the arc surface of the arc-shaped block 413 pushes the arc surface of the locking rod 412, causing the push rod to move further away from the rotating disk 408. The lever 412 slides away from the arc-shaped block 413, thereby causing the limiting plug 414 to be disengaged from the U-shaped slide rail 401. At this time, the compression spring rod 415 rebounds and pushes the sliding seat 402 to slide, thereby driving the drive motor 403 and the wire drawing wheel 404 away from the steel pipe and stopping the wire drawing work on the steel pipe. This prevents the wire drawing wheel 404 from rotating too fast, which would increase the generation of frictional heat, causing the surface temperature of the steel pipe to rise, affecting the physical properties and mechanical strength of the steel pipe, and even causing the steel pipe to deform or reduce its quality. At the same time, the alarm can enable the staff to discover and deal with this situation as soon as possible, ensuring the appearance quality and smoothness of the steel pipe.
