Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel plate welding, in particular to a tungsten carbide hot melting welding composite wear-resistant steel plate production process and equipment thereof. BACKGROUND

[0002] Melting welding is a commonly used welding method in composite steel plate processing. The steel plates at the connection are melted under the action of high temperature, etc. Since the welded steel plates are closely attached together, under the action of temperature field, gravity, etc., without pressure, the molten liquid of the two steel plates will also be mixed. After the temperature decreases, the melted part coagulates, and the two steel plates are firmly welded together. The overall operation is simple. Currently, in the process of melting welding processing, tungsten carbide powder is added to improve the performance of the steel plate, that is, to improve the hardness and toughness of the steel plate, and to reduce maintenance and replacement costs.

[0003] However, in the actual production process, after the base plate is placed in the heating equipment, the alloy powder and tungsten carbide powder need to be spread by manual method. The manual spreading is time-consuming and laborious, and the working effect is low. Moreover, the alloy powder and tungsten carbide powder cannot be evenly distributed by manual spreading, which leads to processing defects in the subsequent production of the composite wear-resistant steel plate. In the heating process, the molten metal powder may flow out from between the two base plates. There is no corresponding cleaning equipment, which leads to traces of molten metal powder flowing at the edges and corners of the processed composite wear-resistant steel plate. Therefore, the composite wear-resistant steel plate needs to be processed again, which is very troublesome. After the processing is completed, the edges and corners of the composite wear-resistant steel plate need to be detected to check whether there are processing gaps. At the same time, the composite wear-resistant steel plate needs to be pulled by manual method to check the stability of the welding of the composite wear-resistant steel plate.

Figure 5 The direction is the basis, in the process of the rotating rod 313 moving to the right following the moving plate 305, the rotating rod 313 will rotate counterclockwise, the metal powder in the moving groove 319 enters the rotating groove 316, when the rotating groove 316 rotates to the opening 320, the metal powder falls on the upper side of the base plate through the opening 320, thereby completing the spreading operation of the metal powder, and the metal powder is more evenly spread.

[0038] As shown in Figure 8 , the moving plate 305 is provided with a flattening assembly, the main function of the flattening assembly is to flatten the metal powder falling on the upper side of the base plate, so that the metal powder is more evenly spread, the flattening assembly comprises a plurality of installation plates 322 slidingly installed on the side wall of the moving groove 319, the plurality of installation plates 322 are correspondingly matched in number and position with the rotating blocks 315, a fixed square rod 326 is slidingly connected in the plurality of installation plates 322, the fixed square rod 326 is fixedly connected with the moving plate 305, a second spring 325 is fixedly connected between the fixed square rod 326 and the installation plate 322, a first trapezoidal plate 323 is fixedly connected to the outer side of the plurality of installation plates 322, a plurality of fixed plates 321 are fixedly connected to the outer side of the moving plate 305, the fixed plates 321 are arranged in pairs on the upper and lower sides of each group, each group of fixed plates 321 is oppositely arranged on the upper and lower sides of the installation plate 322, a slide rod 327 is slidingly connected to the side wall of each fixed plate 321, a second trapezoidal plate 328 is fixedly connected to one end of the slide rod 327, a rolling plate 324 is fixedly connected to the other end of the slide rod 327, a moving ring 330 is slidingly connected to the outer side of the slide rod 327, a third spring 329 is fixedly connected between the moving ring 330 and the rolling plate 324, the contact surfaces of the rotating blocks 315 and the installation plates 322 are smooth;

[0039] First, one mounting plate 322, one rotating block 315, two fixed plates 321 are relatively arranged, second, in the process of counterclockwise rotation of the rotating block 315, the mounting plate 322 is located in the rotating groove 316 in the initial state, the mounting plate 322 is located at the leftmost side of the moving plate 305 at this time, when the mounting plate 322 moves out of the rotating groove 316, the mounting plate 322 is always in contact with the side wall of the rotating groove 316, so that the mounting plate 322 moves to the right relative to the moving plate 305, the mounting plate 322 compresses the second spring 325 at the same time, drives the first trapezoidal plate 323 to move to the right, the first trapezoidal plate 323 and the second trapezoidal plate 328 are in contact, which drives the second trapezoidal plate 328 to move away from each other, the second trapezoidal plate 328 drives the rolling plate 324 to move away from each other through the slide rod 327, the rolling plate 324 is in contact with the metal powder falling on the upper side of the base plate and flattens the metal powder, further improves the spreading effect of the metal powder, makes the metal powder spread more evenly, until the mounting plate 322 enters the rotating groove 316 again, so that the metal powder can be flattened automatically after falling on the upper side of the base plate, the degree of automation and intelligence is high, and in the above working process, the mounting plate 322 is in contact with the rotating groove 316 which has passed through the opening 320, and there is no metal powder in the rotating groove 316, so the overall movement of the mounting plate 322 will not be affected.

[0040] The outer side of each fixed plate 321 is provided with a sliding groove 333, the slide rod 327 penetrates and slidably connects with the sliding groove 333, the side wall of the moving ring 330 is fixedly connected with a connecting plate 331, and the connecting plate 331 and the moving plate 305 are fixedly connected with a fourth spring 332;

[0041] Firstly, the sliding groove 333 is wavy, and in the initial state, the sliding rod 327 is located at the right end of the sliding groove 333 and abuts against the sliding groove 333, and the fourth spring 332 is in a compressed state, so that during the back-and-forth movement of the mounting plate 322, the rolling plate 324 is caused to move up and down relative to the moving plate 305, and after the metal powder is scattered, the double-shaft motor 302 is started again to continue to drive the threaded ring 307 to rotate, so that the moving plate 305 and the rolling plate 324 are located at both ends of the base plate as a whole, and a certain gap is formed between the moving plate 305, the rolling plate 324 and the base plate, and after the composite wear-resistant steel plate is just heated, the threaded ring 307 is rotated, the threaded ring 307 drives the moving plate 305 to move towards the base plate through the threaded rod 306, so that the rolling plate 324 abuts against the outer side wall of the base plate, and the threaded ring 307 is continuously rotated, at this time, the rolling plate 324 cannot continue to move with the moving plate 305 due to the resistance of the base plate, and therefore the rolling plate 324 moves to the left relative to the fixed plate 321 under the restriction of the sliding groove 333 and the sliding rod 327, and the fourth spring 332 is compressed, so that the rolling plate 324 moves forward and backward relative to the moving plate 305 during the up-and-down movement, and the rolling plate 324 abuts against the side wall of the base plate to form a cleaning operation on the liquid metal that may exist on the side wall of the base plate, so as to reduce the existence of the liquid metal flow marks, and further reduce the subsequent cleaning operation. During the above working process, the rolling plate 324 should be avoided to move between the base plates as much as possible;

[0042] Then, after the base plate is cooled as a whole, the threaded ring 307 is rotated to make the distance between the two rolling plates 324 in the minimum state, that is, the mounting plate 322 is located in the rotating groove 316, at this time, the base plate is moved as a whole, so that the rolling plate 324 extends into the two base plates, and then the threaded ring 307 is rotated again to move the moving plate 305 towards the base plate, during which the two rolling plates 324 are caused to move away from each other, and the rolling plate 324 abuts against the base plate to separate the base plates as much as possible, if the stability of the welding between the base plates is general, the base plates will be disconnected under the action of the rolling plate 324, if the welding effect between the base plates is good, no phenomenon will occur, and then the detection operation on the connection stability of the base plates after welding is completed is completed.

[0043] As Figure 6 The extrusion plate 318 is slidably connected in the moving groove 319, the upper side of the extrusion plate 318 is fixedly connected with the upper pressing plate 308, and the first spring 317 is fixedly connected between the upper pressing plate 308 and the moving plate 305;

[0044] When it is needed to put the metal powder into the moving groove 319, the upper pressing plate 308 and the extrusion plate 318 are removed from the moving groove 319, and then the extrusion plate 318 is put into the moving groove 319 again, at this time, the first spring 317 is in the stretched state, and under the action of the first spring 317, the extrusion plate 318 can form the extrusion effect on the metal powder, so that the metal powder can completely enter into the rotating groove 316.

[0045] The pressure sensor is fixedly connected between the moving ring 330 and the rolling plate 324;

[0046] The pressure sensor is a device or apparatus that can sense a pressure signal and can convert the pressure signal into an electrical signal according to a certain rule, when the rolling plate 324 is used to clean the liquid metal possibly existing on the outer side of the substrate, the liquid metal falling on the outer side of the rolling plate 324 can increase the weight of the rolling plate 324, and then the pressure sensor can send a corresponding electrical signal, in this process, the sizes of the electrical signals sent by all the pressure sensors can be compared, if it is found that the electrical signals sent by some pressure sensors are abnormal, the damage of the side wall of the substrate at this position needs to be detected in time.

[0047] The production process of the tungsten carbide hot melting welding composite wear-resistant steel plate comprises the following steps:

[0048] S1, substrate processing: Q235 low carbon steel plate is selected as the substrate, and the oil stains and rust on the surface are cleaned;

[0049] S2, coating film remover: uniformly coating the film remover on the surface of the substrate, the composition including borax and boric acid;

[0050] S3, spreading alloy powder: uniformly spreading the alloy powder on the surface of the film remover, the composition including chromium, boron, silicon, molybdenum and nickel;

[0051] S4, spreading tungsten carbide powder: uniformly spreading the tungsten carbide powder on the surface of the alloy powder;

[0052] S5, scattering slagging agent: scattering the slagging agent on the surface of the tungsten carbide powder;

[0053] S6, heating treatment: pushing the substrate into the heating box 1, heating to 1280℃, keeping warm for 10 minutes, then cooling to 1180℃, keeping warm for 3 hours, and then discharging from the furnace, to obtain the strengthened tungsten carbide wear-resistant composite plate product.

[0054] In the present application, the required metal powder is poured into the moving groove 319, the double-shaft motor 302 is started, the double-shaft motor 302 drives the rotating shaft 303 to rotate, the rotating shaft 303 drives the threaded ring 307 to rotate through the belt pulley assembly 304, since the threaded ring 307 and the threaded rod 306 are threadedly connected, and the threaded rod 306 and the moving frame 301 are slidingly connected, therefore the rotating threaded ring 307 drives the threaded rod 306 to move relative to the moving frame 301, the threaded rod 306 drives the moving plate 305 to move, in the process of moving of the moving plate 305, since the rack 312 and the moving frame 301 are fixedly connected, therefore when the moving plate 305 moves, the gear 309 and the rotating rod 313 will rotate, to Figure 5 the direction as the basis, in the process of the rotating rod 313 moving rightward following the moving plate 305, the rotating rod 313 will rotate counterclockwise, the metal powder in the moving groove 319 enters the rotating groove 316, when the rotating groove 316 rotates to the opening 320, the metal powder falls on the upper side of the base plate through the opening 320, thereby completing the spreading operation of the metal powder, and the spreading of the metal powder is more uniform;

[0055] In the process of counterclockwise rotation of the rotating block 315, the mounting plate 322 is located in the rotating groove 316 in the initial state, the mounting plate 322 is located at the leftmost side of the moving plate 305 at this time, in the process of the mounting plate 322 moving out of the rotating groove 316, the mounting plate 322 is always in abutment with the side wall of the rotating groove 316, therefore the mounting plate 322 moves rightward relative to the moving plate 305, the mounting plate 322 compresses the second spring 325 at the same time, drives the first trapezoidal plate 323 to move rightward, the first trapezoidal plate 323 and the second trapezoidal plate 328 abut to drive the second trapezoidal plate 328 to move away from each other, the second trapezoidal plate 328 drives the rolling plate 324 to move away from each other through the slide rod 327, the rolling plate 324 abuts with the metal powder falling on the upper side of the base plate and flattens the metal powder, further improves the spreading effect of the metal powder, makes the spreading of the metal powder more uniform, until the mounting plate 322 enters the rotating groove 316 again, thereby the metal powder can be flattened again automatically after falling on the upper side of the base plate, the degree of automation and intelligence is high;

[0056] In the initial state, the slide rod 327 is located at the right end of the sliding groove 333 and abuts against the sliding groove 333, and the fourth spring 332 is in a compressed state. Therefore, during the back-and-forth movement of the mounting plate 322, the rolling plate 324 moves up and down relative to the moving plate 305. After the metal powder is scattered, the dual-shaft motor 302 is started again to continue rotating the threaded ring 307, so that the moving plate 305 and the rolling plate 324 as a whole are located at both ends of the base plate and a certain gap exists between the moving plate 305, the rolling plate 324 and the base plate. After the composite wear-resistant steel plate is just heated, the threaded ring 307 is rotated to drive the moving plate 305 to move towards the base plate, so that the rolling plate 324 abuts against the outer sidewall of the base plate. The rolling plate 324 cannot continue to move with the moving plate 305 due to the resistance of the base plate, and thus moves left relative to the fixed plate 321 under the restriction of the sliding groove 333 and the slide rod 327 and compresses the fourth spring 332. Therefore, the rolling plate 324 moves forward and backward relative to the moving plate 305 during the up-and-down movement. The rolling plate 324 abuts against the sidewall of the base plate to clean the liquid metal that may exist on the sidewall of the base plate, reduce the existence of the liquid metal flow marks, and further reduce the subsequent cleaning operation. During the above working process, the rolling plate 324 should be avoided to move between the base plates as much as possible.

[0057] Then, after the base plate is cooled as a whole, the threaded ring 307 is rotated to make the distance between the two rolling plates 324 be in a minimum state, i.e., the mounting plate 322 is located in the rotating groove 316. At this time, the base plate as a whole is moved to make the rolling plate 324 extend into the two base plates. Then, the threaded ring 307 is rotated again to move the moving plate 305 towards the base plate. During this process, the two rolling plates 324 move away from each other, and the rolling plate 324 abuts against the base plate to separate the base plates. If the stability of the welding between the base plates is general, the base plates will be disconnected under the action of the rolling plate 324. If the welding effect between the base plates is good, no phenomenon will occur, and thus the detection operation of the connection stability of the base plates after welding is completed is completed.

[0058] The pressure sensor is a device or apparatus that can sense a pressure signal and convert the pressure signal into an electrical signal according to a certain rule. When the rolling plate 324 is used to clean the liquid metal that may exist on the outer side of the base plate, the weight of the rolling plate 324 increases due to the liquid metal falling on the outer side of the rolling plate 324, and thus the pressure sensor sends a corresponding electrical signal. During this process, the sizes of the electrical signals sent by all the pressure sensors can be compared. If it is found that the electrical signal sent by some pressure sensor is abnormal, the base plate sidewall at this position needs to be detected in time to determine whether the base plate sidewall is damaged.
