Description

Technical Field

[0001] The present invention relates to the processing technology of metal materials, and specifically relates to a plasma cutting device for tinplate. Background Art

[0002] Tinplate refers to a steel plate with a thin layer of metallic tin plated on its surface. Tinplate is made by rolling low-carbon steel into a steel plate about 2 mm thick, followed by pickling, cold rolling, electrolytic cleaning annealing, leveling, trimming, and then further cleaning, electroplating, soft melting, passivation treatment, oiling, and finally cutting into finished tinplate sheets. The tin used for tinplate is high-purity tin (Sn>99.8%). With the development of modern industry, the processing requirements for metal materials are getting higher and higher. Traditional mechanical cutting methods are difficult to meet the requirements of complex shapes, high precision, and high efficiency. Therefore, new cutting technologies need to be introduced to improve the processing quality and production efficiency. Plasma is a high-temperature and high-energy ionized gas state, which has excellent characteristics in cutting. Plasma cutting technology ionizes gas into plasma and uses its high-temperature and high-energy characteristics to heat the metal material to the melting point and simultaneously blow away the molten pool to achieve the purpose of cutting and processing.

[0003] In the Chinese invention patent with the publication number CN118438020A, a plasma cutting auxiliary device is disclosed. This plasma cutting auxiliary device can enable the auxiliary components to achieve large position adjustments by setting adjustable adjustment plates, auxiliary main plates, and auxiliary inner plates. When the height of the cutting surface is relatively high, the workload can be reduced, and it can also protect the connection parts of the cutting device.

[0004] When the existing equipment is in use, when placing the tinplate, since the whole tinplate is relatively long, the two ends of the tinplate are prone to bulge, resulting in a height difference at the cutting position, and thus the cutting head is prone to collide with the tinplate during cutting. At the same time, during the cutting process, the generated gas is prone to diffuse around, and the generated fumes cannot be processed in time, which will affect the operators. Therefore, a plasma cutting device for tinplate has been developed. Summary of the Invention

[0036] Embodiment:

[0037] Please refer toFigures 1-8 , a plasma cutting device for tinplate, comprising an operation table 1, on one side of the operation table 1, a cutting member 11 is slidably installed, and the tinplate is sheared by the cutting member 11.

[0038] In this solution, moving grooves are provided on both sides of the operation table 1, and telescopic components such as electric telescopic rods are arranged on the inner walls of the moving grooves and are connected to an external control device. At the same time, when the electric telescopic rod is started, it drives the cutting member 11 to move. The cutting member 11 is composed of a moving column, a cutting gun and a plasma generator, and the cutting gun and the plasma generator are driven by the moving column to move to a specified position.

[0039] Furthermore, a pretreatment assembly 2 is assembled on both sides of the operation table 1 to cooperate with the pretreatment assembly 2 to limit the tinplate placed on the operation table 1; wherein, the pretreatment assembly 2 includes a bottom plate 21 slidably connected to the operation table 1, a support plate 211 is fixedly installed at the upper end of the bottom plate 21, a support plate 22 is fixedly installed on one side of the support plate 211, an arc plate 221 is fixedly installed at the end of the support plate 22, and an arc groove 222 is provided at the end of the arc plate 221.

[0040] In this embodiment, telescopic components such as electric telescopic rods are provided at the lower end of the support plate 211, and the support plate 211 is driven to move up and down by the electric telescopic rod until the support plate 211 moves to a suitable position and then stops.

[0041] At the same time, a device with power output such as a motor is fixedly installed on one side of the support plate 211, and the rotating shaft 23 is driven to rotate by the motor.

[0042] The height from one end to the other end of the arc plate 221 gradually increases, and the unfolded state of the arc plate 221 is triangular.

[0043] Furthermore, a rotating shaft 23 is rotatably installed at the middle position of the support plate 22, a rotating block 24 is fixedly installed at the end of the rotating shaft 23, a swinging block 25 is rotatably installed at one end of the rotating block 24, and a guiding block 251 is fixedly installed at the end of the swinging block 25, and the outer surface of the guiding block 251 is slidably connected to the inner wall of the arc groove 222.

[0044] Specifically, when the rotating shaft 23 rotates, the rotating block 24 fixedly installed on its outer surface rotates synchronously. Since the swinging block 25 is rotatably installed at the end of the rotating block 24, when the rotating block 24 rotates following the rotating shaft 23, the swinging block 25 rotatably installed on the rotating block 24 is driven to move.

[0045] Since a stop block is provided on the outer surface of the guide block 251 of the swing block 25, the guide block 251 is limited by the stop block, so that when the guide block 251 is forced to move on the inner wall of the arc-shaped groove 222, it is ensured that the guide block 251 is stably located on the inner wall of the arc-shaped groove 222, and the swing block 25 is driven to rotate around the connection with the rotating block 24.

[0046] Further, a second gear 27 is rotatably installed at one end of the rotating block 24 away from the swing block 25, and a protective plate 28 is fixedly installed at the end of the second gear 27 to preliminarily limit the tinplate through the protective plate 28.

[0047] Specifically, when the rotating block 24 rotates following the rotating shaft 23, the second gear 27 rotating on the rotating block 24 is synchronously driven to rotate around the rotating shaft 23, so as to drive the protective plate 28 fixedly installed on the second gear 27 to rotate around the rotating shaft 23 and preliminarily limit the tinplate.

[0048] Further, a first gear 26 is fixedly installed at the connection between the swing block 25 and the rotating block 24. The end of the first gear 26 penetrates and extends to the outside of the rotating block 24, and the outer surface of the first gear 26 meshes with the outer surface of the second gear 27.

[0049] Wherein, a pin shaft is fixedly installed at one end of the swing block 25. The pin shaft is rotatably arranged on the rotating block 24, and the top end of the pin shaft penetrates the rotating block 24 and is fixedly connected with the first gear 26.

[0050] Specifically, when the swing block 25 rotates, the first gear 26 fixedly installed at its end is synchronously driven to rotate. Since the outer surface of the first gear 26 meshes with the outer surface of the second gear 27, when the swing block 25 is forced to rotate, the second gear 27 is driven to rotate synchronously, and the protective plate 28 fixedly installed on the second gear 27 is driven to approach the outer surface of the tinplate.

[0051] Further, an elastic member 281 is fixedly installed on one side of the protective plate 28, and a pressing plate 282 is fixedly installed at the end of the elastic member 281.

[0052] Specifically, the elastic member 281 is an elastic component such as a spring. The pressing plate 282 is supported by the elastic member 281, so that after the pressing plate 282 is attached to the tinplate, the end of the tinplate is locked.

[0053] On both sides of the operating table 1, devices with telescopic functions such as electric telescopic rods are provided. The output end of the electric telescopic rod is connected to one side of the bottom plate 21, and the lower end of the bottom plate 21 is slidably connected to the inner wall on one side of the operating table 1.

[0054] When the electric telescopic rod is started, it synchronously drives the base plate 21 fixedly installed at its output end to move, wherein the moving trajectories of the two electric telescopic rods are inclined, and the cross-section of the moving trajectories of the two electric telescopic rods is in an eight-shaped shape, so that when the entire pretreatment component 2 moves toward the other end of the tinplate, it slowly stretches outward to ensure the overall flatness of the tinplate.

[0055] A telescopic rod is provided at the end of the protective plate 28, and the length of the telescopic rod is the same as the width of the tinplate. At the same time, a scraper is provided on the outer surface of the telescopic rod. Two pretreatment components 2 are arranged in sequence. When the pretreatment component 2 moves, the scraper is used to double-clear impurities on the outer surface of the tinplate, which helps to ensure the stability of the arc during the cutting process and improve the cutting effect.

[0056] Furthermore, a cleaning component 3 is mounted on the inner wall of the operating table 1, and the gas generated during cutting is processed by the cleaning component 3; the cleaning component 3 includes a fixed plate 31 slidably connected to the operating table 1, a driving member 32 is fixedly installed at the end of the fixed plate 31, and the output end of the driving member 32 passes through and extends to the outside of the fixed plate 31, and a driving plate 321 is fixedly installed at the output end of the driving member 32.

[0057] In this embodiment, the driving member 32 is a device with power output such as a motor, and is connected to an external control device. When the driving member 32 is started, it synchronously drives the driving plate 321 arranged at its output end to rotate.

[0058] Furthermore, a driving rod 33 is rotatably mounted at the end of the driving plate 321 and near the edge, and a movable plate 34 is rotatably mounted at the end of the driving rod 33. A sliding groove 311 is provided at the end of the fixed plate 31, and the inner wall of the sliding groove 311 is slidably connected to the outer surface of the lower end of the movable plate 34.

[0059] Specifically, when the driving plate 321 rotates, the driving rod 33 installed at its end drives the movable plate 34 to move. Since the outer surface of the lower end of the movable plate 34 is slidingly connected to the inner wall of the slide groove 311, the driving rod 33 drives the movable plate 34 to move along the inner wall of the slide groove 311.

[0060] At the same time, guide rails are provided on both sides of the upper end of the fixed plate 31, and the outer surfaces of the guide rails are slidably connected to the inner walls of both sides of the movable plate 34, so as to ensure that the entirety remains stable when the movable plate 34 moves.

[0061] Further, a movable rod 35 is rotatably installed at the end of the movable plate 34. The end of the movable rod 35 penetrates and extends to the other end of the movable plate 34, and an adjusting block 38 is fixedly installed at the lower end of the movable rod 35. An adjusting plate 36 is fixedly installed on one side of the fixed plate 31. An adjusting groove 37 is formed at the end of the adjusting plate 36. The outer surface of the adjusting block 38 away from the movable rod 35 is slidably connected to the inner wall of the adjusting groove 37.

[0062] Specifically, when the movable plate 34 moves, it synchronously drives the movable rod 35 rotatably installed at its end to move. Since the adjusting block 38 is fixedly installed at the end of the movable rod 35, the cross-section of the adjusting block 38 is Z-shaped. At the same time, the outer surface of the adjusting block 38 away from the movable rod 35 is slidably connected to the inner wall of the adjusting groove 37.

[0063] Both sides of the adjusting groove 37 are in a horizontal state, and the middle position is convex, so that when the adjusting block 38 moves on the inner wall of the adjusting groove 37, it rotates slowly, thereby driving the movable rod 35 to rotate until it reaches the best position and then stops.

[0064] Further, a collecting cylinder 39 is fixedly installed at the upper end of the movable rod 35. A power block 391 is rotatably installed on the inner wall of the collecting cylinder 39 and away from the central position. A rotating plate 392 is rotatably installed on the outer surface of the power block 391.

[0065] Specifically, a device with power output such as a motor is provided at the end of the collecting cylinder 39. The power block 391 is driven to rotate by the motor, and the rotating plate 392 rotatably installed on its outer surface is used to collect the gas generated in the operating table 1. An annular groove is formed on the inner wall of the collecting cylinder 39, and the inner wall of the annular groove is slidably connected to the outer surface of the rotating plate 392 away from the power block 391.

[0066] A collecting plate is provided at the end of the collecting cylinder 39 to collect the impurities generated during cutting, which is convenient for subsequent cleaning.

[0067] A transmission block is fixedly installed at the lower end of the fixed plate 31. Two screw rods are rotatably installed inside the transmission block, and the cross-sections of the two screw rods are perpendicular. A device with power output such as a motor is provided at the end of each screw rod. The position of the cleaning assembly 3 is adjusted by the vertically and horizontally arranged screw rods, so that the cleaning assembly 3 moves synchronously with the cutting end, thereby facilitating the collection of the gas and impurities generated during cutting.

[0068] The control device can select a single-chip microcomputer as the control terminal. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which is composed of an arithmetic unit, a controller, a memory, input and output devices, etc., and is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes more on self-supply (without external hardware) and cost savings. Its greatest advantage is its small size, which can be placed inside the instrument, but it has a small storage capacity, simple input and output interfaces, and low power consumption.

[0069] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
