Description

Technical Field

[0001] This utility model relates to the field of strip steel welding technology, specifically to an auxiliary device for welding galvanized strip steel processing. Background Technology

[0002] Welding is a crucial step in the processing of galvanized steel strip, and the quality of welding directly affects the overall performance and service life of the steel strip product.

[0003] In traditional welding processes, the lack of effective limiting measures makes the strip steel prone to displacement and shaking during welding, resulting in inaccurate welding positions and affecting welding quality. In some applications with high welding precision requirements, such as automobile manufacturing and home appliance production, deviations in welding positions may lead to a decrease in the sealing performance, strength, and other properties of the product, or even safety hazards. On the other hand, some welding methods are not perfect in fixing the two sections of strip steel. Chinese patent CN219787205U discloses a welding auxiliary device for galvanized strip steel. Its activation control component controls the pressure plate to move closer to the fixing plate, reducing the distance between the pressure plate and the fixing plate until both the pressure plate and the fixing plate are in contact with the strip steel and are tightly pressed together, so that the joint between the tail of the steel coil and the head of the next steel coil is located at the operating hole, and the operator welds the joint at the operating hole.

[0004] However, in practical use, the two sections of steel strip to be welded need to be pressed together simultaneously, requiring multiple operators to work together to place the two sections of steel strip in the designated position and control them to prevent displacement. This operation is inconvenient and inefficient. To address this, we propose an auxiliary device for welding galvanized steel strip. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary device for processing and welding galvanized steel strip, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a welding auxiliary device for galvanized strip steel processing, comprising a support platform, a welding platform mounted on the top surface of the support platform, two mounting plates mounted on both sides of the top surface of the welding platform, a guide roller rotatably mounted between the two mounting plates on the same side, a sliding groove formed on the surface of the mounting plate, a slider slidably mounted inside the sliding groove, an adjusting component for driving the slider movement mounted on one side of the mounting plate, and a limit roller rotatably mounted between the two sliders;

[0007] Two mounting blocks are installed on one side of the support platform. A telescopic rod is installed on the top surface of the mounting block. A pressure plate is installed at one end of the inner rod of the telescopic rod. An elastic element is provided between the pressure plate and the mounting block. An abutment component that can move laterally to resist the movement of the pressure plate is installed on one side of the support platform.

[0008] Preferably, the adjusting component is a first electric push rod, the outer rod of the first electric push rod is installed on one side of the mounting plate, the inner rod of the first electric push rod movably passes through the mounting plate, and one end of the inner rod of the first electric push rod is fixed to the slider.

[0009] Preferably, the elastic element is a spring, with one end of the spring mounted on one side of the pressure plate and the other end of the spring mounted on one side of the mounting block.

[0010] Preferably, the abutment component includes a linear motor, which is mounted on one side of the support platform. A movable plate is mounted on the moving end of the linear motor, and a second electric push rod is mounted on the top surface of the movable plate. An abutment block is mounted on the output end of the second electric push rod.

[0011] Preferably, the cross-section of the abutting block is trapezoidal, and one side of the abutting block is provided with an inclined surface for abutting the pressure plate.

[0012] Preferably, the linear motor is fixedly mounted on one side of the support platform via a connecting block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This auxiliary device for processing and welding galvanized steel strip, when in use, turns on the switch of the first electric push rod, which drives the slider to move, thereby changing the position of the limiting roller and adjusting the distance between the limiting roller and the guide roller so that the distance between the limiting roller and the guide roller matches the thickness of the galvanized steel strip. Then, the galvanized steel strip is passed between the left guide roller and the limiting roller. The galvanized steel strip is limited by the guide roller, the limiting roller and the two mounting plates, so that the part of the galvanized steel strip to be welded will not deviate when it moves to the surface of the welding table, ensuring its accurate position.

[0015] 2. This auxiliary device for processing and welding galvanized steel strips, by turning on the switch of the linear motor, drives the moving plate, the second electric push rod, and the contact block to move laterally. The inclined surface of the contact block abuts against the left pressure plate and moves downward, so that the left pressure plate presses the left strip tightly. Then, another strip is passed between the right guide roller and the limit roller. The contact block is controlled to continue to move laterally, so that the inclined surface of the contact block abuts against the right pressure plate and moves downward, until the bottom surface of the contact block abuts against both pressure plates at the same time. This allows the two pressure plates to press the two strips in sequence, which facilitates the sequential operation of moving the two strips to the designated position and fixing them, thus ensuring operational efficiency.

[0020] 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.

[0021] Example 1

[0022] Please refer to Figure 1-3 As shown, this utility model provides a welding auxiliary device for galvanized strip steel processing, including a support platform 1, a welding platform 2 installed on the top surface of the support platform 1, two mounting plates 3 installed on both sides of the top surface of the welding platform 2, a guide roller 4 rotatably installed between the two mounting plates 3 on the same side, a sliding groove 5 opened on the surface of the mounting plate 3, a slider 7 slidably installed inside the sliding groove 5, an adjusting component for driving the slider 7 to move is installed on one side of the mounting plate 3, and a limit roller 8 rotatably installed between the two sliders 7;

[0023] Two mounting blocks 9 are installed on one side of the support platform 1. A telescopic rod 10 is installed on the top surface of the mounting block 9. A pressure plate 11 is installed at one end of the inner rod of the telescopic rod 10. An elastic element is provided between the pressure plate 11 and the mounting block 9. A counteracting component that can move laterally to counteract the movement of the pressure plate 11 is installed on one side of the support platform 1.

[0024] Specifically, by adjusting the distance between the guide roller 4 and the limiting roller 8, the device can limit the strip steel of different thicknesses. The abutment component can press the two pressure plates 11 in two stages, so that the two strip steels can be sent into the designated positions and fixed respectively.

[0025] Specifically, the adjusting component is the first electric push rod 6. The outer rod of the first electric push rod 6 is installed on one side of the mounting plate 3, and the inner rod of the first electric push rod 6 moves through the mounting plate 3. One end of the inner rod of the first electric push rod 6 is fixed to the slider 7. When the switch of the first electric push rod 6 is turned on, the slider 7 can be driven to move, thereby changing the distance between the limit roller 8 and the guide roller 4.

[0026] Specifically, the elastic element is spring 12. One end of spring 12 is installed on one side of pressure plate 11, and the other end of spring 12 is installed on one side of mounting block 9. When pressure plate 11 is not pressed down, spring 12 drives pressure plate 11 to move upward away from welding table 2.

[0027] The contact assembly includes a linear motor 13, which is mounted on one side of the support platform 1. A moving plate 14 is mounted on the moving end of the linear motor 13, and a second electric push rod 15 is mounted on the top surface of the moving plate 14. A contact block 16 is mounted on the output end of the second electric push rod 15. The contact block 16 has a trapezoidal cross-section, and one side of the contact block 16 is provided with an inclined surface for contacting the pressure plate 11. The linear motor 13 is fixedly mounted on one side of the support platform 1 via a connecting block. By turning on the switch of the linear motor 13, the moving plate 14, the second electric push rod 15, and the contact block 16 are driven to move laterally. During the lateral movement of the contact block 16, it can press down on the two pressure plates 11, causing the pressure plates 11 to press down against the surface of the strip steel. By controlling the second electric push rod 15 to open, the contact block 16 can be driven to move upward or downward, thereby adjusting the height position of the contact block 16 and changing the height position of the pressure plate 11 when the bottom surface of the contact block 16 presses down on the pressure plate 11, so that the pressure plate 11 can press down on strip steel of different thicknesses.

[0028] Working principle: This utility model is an auxiliary device for welding galvanized steel strip. When in use, the switch of the first electric push rod 6 is turned on, which drives the slider 7 to move, thereby changing the position of the limiting roller 8 and adjusting the distance between the limiting roller 8 and the guide roller 4 so that the distance between the limiting roller 8 and the guide roller 4 matches the thickness of the galvanized steel strip. Then, the galvanized steel strip is passed between the left guide roller 4 and the limiting roller 8. The galvanized steel strip is limited by the guide roller 4, the limiting roller 8 and the two mounting plates 3, so that the part of the galvanized steel strip to be welded will not deviate when it moves to the surface of the welding table 2, ensuring its accurate position.

[0029] After the strip to be welded is moved to the middle of the top surface of the welding table 2, the switch of the linear motor 13 is turned on, which drives the moving plate 14, the second electric push rod 15 and the contact block 16 to move laterally. The inclined surface of the contact block 16 abuts against the left pressure plate 11 and moves downward, so that the left pressure plate 11 presses the left strip tightly. Then, the distance between the right guide roller 4 and the limiting roller 8 is adjusted in the same way, and another strip is passed between the right guide roller 4 and the limiting roller 8. The contact block 16 is controlled to continue to move laterally, so that the inclined surface of the contact block 16 abuts against the right pressure plate 11 and moves downward, until the bottom surface of the contact block 16 abuts against both pressure plates 11 at the same time, so that the two pressure plates 11 press the two strips in sequence.

[0030] By controlling the second electric push rod 15 to open, the contact block 16 can be moved up or down, thereby adjusting the height position of the contact block 16 and changing the height position of the pressure plate 11 when the bottom surface of the contact block 16 presses against the pressure plate 11, so that the pressure plate 11 can press against strip steel of different thicknesses.
