Description

Technical Field

[0001] The invention relates to the technical field of composite wear-resistant plate processing, in particular to a processing method for preventing composite wear-resistant plates from deforming. Background Art

[0002] Wear-resistant plates are widely used in metallurgy, building materials, chemicals, electric power and other industries to protect the parts of conveying equipment, powder equipment, transport vehicles, engineering machinery and other equipment from material impact and wear. Wear-resistant steel plates have high wear resistance, impact resistance, and weldability. They can be directly cut, welded, punched and processed like steel plates, and processed into engineering parts to meet wear conditions and put into use.

[0003] The existing technology adopts the method of surfacing welding, using special surfacing welding equipment, to surfacing a certain thickness of wear-resistant layer with high hardness and excellent wear resistance on the surface of ordinary low-carbon steel or low-alloy steel plate with good plasticity. Due to the large differences in the chemical composition and properties of the wear-resistant layer and the substrate, the compatibility and bonding between the wear-resistant layer and the substrate materials are poor. While improving the wear resistance of the wear-resistant layer material, a large stress concentration will be generated at the bonding surface, causing the wear-resistant plate to warp and deform under the influence of welding stress and thermal stress, affecting the subsequent manufacturing process and structural reliability. In order to avoid warping and deformation of the composite wear-resistant plate after welding and reduce the leveling process, a processing method for preventing deformation of the composite wear-resistant plate is proposed. Summary of the invention

[0004] Technical problem solved: In view of the deficiencies in the prior art, the present invention provides a processing method for preventing deformation of a composite wear-resistant plate, thereby solving the problem that the composite wear-resistant plate is prone to warping and deformation after welding.

[0005] To achieve the above object, the present invention provides the following technical solution: a processing method for preventing deformation of a composite wear-resistant plate, specifically comprising the following steps:

[0006] Step 1: Material screening: Select composite wear-resistant plates of different standard thicknesses produced by the workshop, analyze the materials of the composite wear-resistant plates, classify the composite wear-resistant plates with the same material for the steel plate and the wear-resistant layer into the same category, and classify them according to the thickness of the steel plate and the wear-resistant layer, and import the sorted material information into the information storage unit for storage;

[0007] Step 2, pressure test: set an area of ​​standard length and width as the standard area, cut the composite wear-resistant plate according to the standard area to obtain the test plate, place two test plates horizontally on the pressure test piece with pressure sensor, and then weld the two test plates with welding materials. During the welding process, the two test plates squeeze the pressure sensor in the pressure test piece due to stress changes, and import the squeezing force and welding material into the information storage unit for storage;

[0008] Step 3, balance test: take another test plate, put its welding side in contact with the horizontal plane, then use a tensile scale to lift the side of the test plate corresponding to the welding side, and when the tensile scale reaches the measured extrusion force, measure the inclination angle of the test plate, record the inclination angle as the balance inclination angle of the test plate under the welding of the welding material, and import the obtained balance inclination angle into the information storage unit for storage;

[0009] Step 4, chart analysis: the information analysis unit retrieves the balance tilt angles of the test plates of the same type with equal wear-resistant layer thickness but unequal steel plate thickness under the same welding material welding from the information storage unit through the central processing module, constructs a plane coordinate system with the steel plate thickness value as the X-axis and the balance tilt angle as the Y-axis, and displays the trend of the balance tilt angles of different steel plate thicknesses; retrieves the balance tilt angles of the test plates of the same type with equal steel plate thickness but unequal wear-resistant layer thickness under the same welding material welding from the information storage unit, constructs a plane coordinate system with the wear layer thickness value as the X-axis and the balance tilt angle as the Y-axis, and displays the trend of the balance tilt angles of different wear layer thicknesses;

[0010] Step 5. Tilt prediction: When welding two composite wear-resistant plates, it is found that the wear-resistant layer thickness and steel plate thickness are not stored in the information storage unit. Select the same classification as the wear-resistant layer and steel plate material of the composite wear-resistant plate from the information storage unit, and select the tested wear-resistant layer thickness closest to the wear-resistant layer thickness of the composite wear-resistant plate and the tested steel plate thickness closest to the steel plate thickness of the composite wear-resistant plate. According to the trend analysis in step 4, obtain two groups of balanced tilt angles, and then calculate the average value of the two groups of balanced tilt angles to obtain a new balanced tilt angle as the tilt angle of the two composite wear-resistant plates before welding.

[0011] By adopting the above technical scheme, the extrusion pressure generated by the warping deformation of the composite wear-resistant plate welding on the pressure sensor is tested, and the balance tilt angle of the corresponding composite wear-resistant plate is obtained in conjunction with the tensile scale. The composite wear-resistant plate is tilted to the other side at a corresponding angle before surfacing. After welding, the purpose of flattening the composite wear-resistant plate can be achieved. Through the classification of the test plates and the analysis of the wear-resistant layer thickness and the steel plate thickness and the balance tilt angle, the balance tilt angle in the actual composite wear-resistant plate welding process can be predicted, which greatly improves the scope of application and practicality.

[0012] The present invention is further configured as follows: the central processing module is bidirectionally connected with the information storage unit and the information analysis unit respectively, wherein the information storage unit includes a pressure sensor, a classification storage module and a tilt recording module, and the pressure sensor and the tilt recording module are both connected to the classification storage module.

[0013] The present invention is further configured as follows: the information analysis unit includes a curve analysis module and a tilt prediction module, and the curve analysis module is connected to the tilt prediction module.

[0014] The present invention is further configured as follows: the pressure testing piece includes a base, a motor fixing box is fixedly installed on the top of the base, a placing platform is fixedly installed on the top of the motor fixing box, guide plates are passed through and slidably connected on both the left and right sides of the placing platform, one end of the guide plate away from the placing platform is fixedly connected to a limit plate by a first adjusting bolt, and an adjusting piece compatible with the pressure sensor is fixedly installed on the top of the opposite side of the two limit plates.

[0015] The present invention is further configured as follows: the placement platform includes a square frame and a cover plate, the front and rear sides of the left and right sides of the square frame are both provided with open grooves adapted to the guide plate, a plurality of pins are fixedly installed on the bottom of the cover plate, and a plurality of blind holes adapted to the pins are opened on the top of the square frame.

[0016] By adopting the above technical solution, the cover plate is used as a welding receiving platform for the two test plates. With the cooperation of the pin shaft and the blind hole, the connection stability between the cover plate and the frame is ensured, while providing convenient conditions for the disassembly and assembly of the cover plate.

[0017] The present invention is further configured as follows: a servo motor is fixedly installed inside the motor fixing box, the output end of the servo motor passes through the motor fixing box and the square frame in sequence and is fixedly connected to a driving gear through a coupling, and grooves matching the driving gear are provided on opposite sides of the two guide plates, and teeth matching the driving gear are fixedly connected inside the grooves.

[0018] By adopting the above technical solution, in conjunction with the servo motor, driving gear and teeth, the movement of the guide plate is facilitated, so that the guide plate can drive the limit plate to move, and then the pressure test piece can be unfolded when needed, and can be effectively retracted and stored when not needed, thereby reducing the floor space.

[0019] The present invention is further configured as follows: the adjusting member includes a positioning plate, the top of the positioning plate is threadedly connected with a second adjusting bolt, the bottom of the second adjusting bolt is rotatably connected to the top of the pressure sensor through a bearing, the bottom of the pressure sensor is fixedly connected with a contact plate, the side of the limit plate is evenly spaced from top to bottom with a plurality of threaded holes compatible with the first adjusting bolt, the opposite side of the two limit plates and the front and rear sides of the guide plate are fixedly connected with a clamping plate, the side of the clamping plate away from the limit plate is in sliding contact with one side of the contact plate, thereby ensuring that the contact plate can only move up and down, and when the test plate is placed on the cover plate, a pad is placed on the guide plate to ensure that the bottom horizontal plane of the test plate and the top horizontal plane of the cover plate remain at the same level.

[0020] By adopting the above technical solution, the height of the pressure sensor from the ground is adjusted by rotating the second adjusting bolt to achieve fine-tuning. In conjunction with the setting of the contact plate, the test plate transmits the extrusion force to the pressure sensor through the contact plate, thereby avoiding damage to the pressure sensor caused by direct extrusion of the test plate. Under the setting of the second adjusting bolt and the threaded hole, coarse adjustment is achieved by cooperating with the second adjusting bolt and different bolt holes, thereby ensuring that the contact plate can stably contact the top surface of the test plate.

[0021] The present invention provides a processing method for preventing deformation of a composite wear-resistant plate. It has the following beneficial effects:

[0022] (1) The processing method for preventing deformation of the composite wear-resistant plate tests the extrusion pressure on the pressure sensor caused by the warping deformation of the composite wear-resistant plate during welding, and obtains the equilibrium tilt angle of the corresponding composite wear-resistant plate by using a tensile scale. The composite wear-resistant plate is tilted to the other side at a corresponding angle before surfacing. After welding, the composite wear-resistant plate can be flattened. In addition, the equilibrium tilt angle in the actual composite wear-resistant plate welding process can be predicted by classifying the test plates and analyzing the thickness of the wear-resistant layer and the thickness of the steel plate and the equilibrium tilt angle, thereby greatly improving the scope of application and practicality.

[0023] (2) The processing method for preventing deformation of the composite wear-resistant plate uses the cover plate as a welding receiving platform for two test plates. With the cooperation of the pin shaft and the blind hole, the connection stability between the cover plate and the frame is ensured, while providing convenient conditions for the disassembly and assembly of the cover plate.

[0024] (3) The processing method for preventing the deformation of the composite wear-resistant plate facilitates the movement of the guide plate by coordinating the servo motor, the driving gear and the teeth, so that the guide plate can drive the limit plate to move, thereby allowing the pressure test piece to be unfolded when needed and effectively retracted and stored when not needed, thereby reducing the floor space.

[0025] (4) The processing method for preventing deformation of the composite wear-resistant plate adjusts the height of the pressure sensor from the ground by rotating the second adjusting bolt to achieve fine adjustment. In conjunction with the setting of the contact plate, the test plate transmits the extrusion force to the pressure sensor through the contact plate, thereby avoiding damage to the pressure sensor caused by direct extrusion of the test plate. Under the setting of the second adjusting bolt and the threaded hole, coarse adjustment is achieved by cooperating with the second adjusting bolt and different bolt holes, thereby ensuring that the contact plate can stably contact the top surface of the test plate.

[0039] Step 2, pressure test: set an area of ​​standard length and width as the standard area, cut the composite wear-resistant plate according to the standard area to obtain a test plate, place two test plates horizontally on the cover plate 18, and then weld the two test plates with welding materials. During the welding process, the two test plates squeeze the contact plate 27 due to stress changes, and the pressure sensor 4 is subjected to squeezing force. After the welding is completed, the squeezing force and the welding material are introduced into the classification storage module 5 in the information storage unit 2 for storage;

[0040] Step 3, balance test: take another test plate, put its welding side in contact with the horizontal plane, then use a tensile scale to lift the side of the test plate corresponding to the welding side, and when the tensile scale reaches the measured extrusion force, measure the inclination angle of the test plate, and record the inclination angle as the balance inclination angle of the test plate under the welding of the welding material, and import the obtained balance inclination angle into the classification storage module 5 in the information storage unit 2 for storage;

[0041] Step 4, chart analysis: the information analysis unit 3 retrieves the balance tilt angles of the test plates of the same type with equal wear-resistant layer thickness but unequal steel plate thickness under welding with the same welding material from the information storage unit 2 through the central processing module 1, constructs a plane coordinate system with the steel plate thickness value as the X-axis and the balance tilt angle as the Y-axis, and displays the trend of the balance tilt angles of different steel plate thicknesses. The information analysis unit 3 retrieves the balance tilt angles of the test plates of the same type with equal steel plate thickness but unequal wear-resistant layer thickness under welding with the same welding material from the information storage unit 2, constructs a plane coordinate system with the wear layer thickness value as the X-axis and the balance tilt angle as the Y-axis, and displays the trend of the balance tilt angles of different wear layer thicknesses;

[0042] Step 5, tilt prediction: when welding two composite wear-resistant plates, it is found that the wear-resistant layer thickness and steel plate thickness are not stored in the classification storage module 5, and the classification with the same material as the wear-resistant layer and steel plate of the composite wear-resistant plate is selected from the classification storage module 5, and the curve analysis module 7 selects the tested wear-resistant layer thickness closest to the wear-resistant layer thickness of the composite wear-resistant plate and the tested steel plate thickness closest to the steel plate thickness of the composite wear-resistant plate, and obtains two sets of balanced tilt angles according to the trend analysis in step 4, and then the tilt prediction module 8 averages the two sets of balanced tilt angles to obtain a new balanced tilt angle as the tilt angle of the two composite wear-resistant plates before welding.

[0043] As a preferred solution, Figure 2 As shown, the central processing module 1 is bidirectionally connected with the information storage unit 2 and the information analysis unit 3 respectively.

[0044] Specifically, as attached Figure 3 As shown, the information storage unit 2 includes a pressure sensor 4 , a classification storage module 5 and a tilt recording module 6 , and both the pressure sensor 4 and the tilt recording module 6 are connected to the classification storage module 5 .

[0046] As a preferred solution, when the test board is placed for testing, the servo motor 21 is controlled to rotate clockwise, so that the driving gear 22 rotates, and the teeth 24 are squeezed to make the two guide plates 13 move away from the frame 17. After moving to a position suitable for the test board, the servo motor 21 is stopped. Figure 5 As shown, a pad is placed on the guide plate 13, and then the test plate is placed on the pad and cover plate 18, and the second adjusting bolt 26 is turned so that the pressure sensor 4 drives the contact plate 27 to move downward until it contacts the top surface of the test plate. At this time, the pressure of the pressure sensor 4 is zero, and then the two test plates are welded using welding materials. During the welding process, the test plate warps and squeezes the contact plate 27, squeezing the pressure sensor 4. The extrusion pressure information measured by the pressure sensor 4 is transmitted to the classification storage module 5 for storage.
