Description

Technical Field

[0001] This utility model relates to the field of heat exchanger tube processing technology, specifically to an online intelligent shearing and welding device for heat exchanger tubes. Background Technology

[0002] Titanium and titanium alloy welded heat exchange tubes possess characteristics such as low density, high specific strength, good corrosion resistance, low thermal conductivity, non-toxicity, non-magnetic properties, good weldability, good biocompatibility, and strong surface decorative properties. They are widely used in aerospace, chemical, petroleum, power, medical, construction, and sporting goods industries. Titanium and titanium alloy welded heat exchange tubes are manufactured from titanium strips on an automated welded pipe production line. The inlet section of this line mainly includes an uncoiler, leveler, shearing and welding machine, and looper. The uncoiler unwinds rolls of titanium strip, which are then leveled by the leveler and fed into the shearing and welding machine. Irregular ends are cut and welded. The titanium strip is then sent to the looper storage silo to ensure sufficient reserves for the welded pipe production line, guaranteeing continuous and normal operation. Because the joined titanium strips undergo subsequent processes such as loopering, milling, and rolling, high weld quality is required to withstand the complex stresses during tension, rotation, and bending. Titanium strip joint welds are prone to breakage. Fracture will severely affect the efficiency of the production line and the yield rate.

[0003] Traditional welded pipe production lines mostly rely on manual welding due to the narrow width and thinness of the titanium strips. Manual welding is inefficient, and the weld quality is highly dependent on the welder's skill level, leading to significant uncertainty. As welded pipe production lines produce larger and more demanding products with increasingly stringent quality requirements, existing technologies can no longer meet manufacturers' needs for improved production line efficiency, yield, pass rate, and labor productivity. Utility Model Content

[0004] The purpose of this invention is to provide an online intelligent shearing and welding device for heat exchange tubes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an online intelligent shearing and welding device for heat exchange tubes, comprising:

[0006] A support platform, on the upper side of which a guide assembly, a first limiting assembly, a cutting assembly, a second limiting assembly, and an end welding assembly are sequentially installed from left to right. A control box is installed on the support platform, and the control box is electrically connected to the guide assembly, the first limiting assembly, the cutting assembly, the second limiting assembly, and the end welding assembly, respectively.

[0007] An uncoiler is located to the left of the support platform.

[0008] Furthermore, the guiding assembly includes a first gantry frame, on which two first cylinders are mounted. The telescopic ends of the two first cylinders are connected to a movable seat. The movable seat is equipped with two second cylinders. The telescopic ends of the two second cylinders are connected to a lifting frame. An upper roller and a lower roller arranged side by side are rotatably mounted inside the lifting frame. A first motor is connected to the rear side of the lifting frame, and the output end of the first motor is connected to the lower roller.

[0009] The bottom ends of the first gantry frame are connected to the upper side of the support platform;

[0010] By coordinating the first and second cylinders, the moving seat and lifting frame can be moved precisely, thereby driving the upper and lower rollers to accurately guide the strip, ensuring that the strip always maintains the correct direction and position during processing, thus improving processing quality.

[0011] Furthermore, the first limiting component includes a second gantry frame, on the top of which two third cylinders are mounted. The telescopic ends of the two third cylinders penetrate the top wall of the second gantry frame. The telescopic ends of the two third cylinders are connected to a mounting frame. Inside the mounting frame, two first guide rollers arranged vertically are rotatably mounted. A double-headed telescopic cylinder is mounted on the top inner wall of the mounting frame. Both output ends of the double-headed telescopic cylinder are connected to a slide block. The bottom of the slide block is rotatably connected to a second guide roller. The second guide roller is located to the right of the first guide roller. A second motor is mounted on the rear side of the mounting frame. The output end of the second motor is connected to the first guide roller located below.

[0012] The bottom ends of the second gantry frame are connected to the upper side of the support platform;

[0013] It can effectively limit the strip, ensuring that the strip will not deviate or shake during processing, thus improving processing accuracy and stability.

[0014] Furthermore, the inner wall of the mounting bracket is fixed with slide rails corresponding to the positions of the two slide blocks, and the slide blocks are slidably mounted on the slide rails.

[0015] Furthermore, the structure of the second limiting component is exactly the same as that of the first limiting component, which further improves the precision and stability of strip processing and ensures the consistency of product quality.

[0016] Furthermore, the cutting assembly includes a cutting machine body, on which a cutting passage cavity is formed through the left and right sides of the cutting machine body, and a cutting groove is formed in the middle of the bottom wall of the cutting passage cavity. Two fourth cylinders are installed on the top of the cutting machine body, and the telescopic ends of the two fourth cylinders slide into the cutting passage cavity and are connected to a cutting blade.

[0017] The cutting assembly uses the extension and retraction of the fourth cylinder to move the cutting blade up and down within the cutting cavity, enabling precise cutting.

[0018] Furthermore, the end welding assembly includes a welding seat, a first pressure block on the left side of the welding seat, a fifth cylinder connected to the front and rear ends of the lower side of the first pressure block, a second pressure block on the right side of the welding seat, a sixth cylinder connected to the front and rear ends of the lower side of the second pressure block, a seventh cylinder between the sixth cylinder and the fifth cylinder, a transmission box connected to the telescopic ends of the two seventh cylinders, a lead screw rotatably connected inside the transmission box, a nut seat sleeved on the lead screw, a welding gun connected to the bottom end of the nut seat, a third motor connected to the front side of the transmission box, and the output end of the third motor connected to the lead screw;

[0019] The cylinder seat of the fifth cylinder is embedded in the welding seat, the cylinder seat of the sixth cylinder is embedded in the welding seat, and the cylinder seat of the seventh cylinder is embedded in the welding seat.

[0020] The fifth cylinder moves the first pressure block downward to squeeze and fix the head of the strip. The sixth cylinder moves the second pressure block downward to squeeze and fix the tail of the strip, ensuring the stability of the welding between the head and tail. At the same time, the seventh cylinder moves the transmission box downward, thereby moving the welding torch downward. The third motor moves the welding torch horizontally, thus achieving welding.

[0021] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0022] 1. By integrating the guiding assembly, the first limiting assembly, the cutting assembly, the second limiting assembly, and the end welding assembly onto the same support platform and centrally controlling them through a control box, the entire process of heat exchange tube strip from uncoiling, guiding, shearing to welding is automated, reducing manual intervention, improving production efficiency, and reducing processing errors caused by human operation, thus ensuring the stability of product quality.

[0023] 2. Through precise shearing and welding operations, continuous production of strip material is achieved, avoiding production interruptions caused by irregular strip beginnings and ends, ensuring the continuity of heat exchange tube production, and effectively improving production efficiency.

[0024] 3. By setting the first and second limiting components, the position of the strip can be precisely adjusted in the vertical and horizontal directions to ensure that the vertical and horizontal positions of the strip meet the requirements during the shearing and welding process, thereby improving the accuracy of shearing and welding.

[0025] 4. The cutting assembly can cut the irregular ends of the strip into flat and regular shapes, creating favorable conditions for welding. The end welding assembly uses a cylinder to control the pressure block to fix the strip, and then the welding gun performs the welding, ensuring the stability and reliability of the welding, improving the welding quality, and thus ensuring the overall quality of the heat exchange tube.

[0054] The cutting assembly 40 drives the cutting blade 45 to move up and down within the cutting cavity 42 via the operation of the fourth cylinder 44, enabling precise cutting action.

[0055] The end welding assembly 60 includes a welding seat 61. A first pressure block 62 is provided on the left side of the welding seat 61.

[0058] In this utility model, after the strip material on the uncoiler 80 is produced, the tail of the strip material moves to the cutting assembly 40. The control box 70 controls the fourth cylinder 44 in the cutting assembly 40 to work and drive the cutting blade 45 to move and cut the irregular part of the tail of the strip.

[0060] The strip head enters between the two first guide rollers 34 of the first limiting assembly 30, and then passes between the two second guide rollers 37. The first limiting assembly 30 can precisely adjust the position of the strip in the vertical and horizontal directions to ensure that the vertical and horizontal positions of the strip meet the requirements during the shearing and welding process.

[0061] The strip head continues to travel to the cutting assembly 40, where the cutting assembly 40 cuts the irregular portion of the strip head;

[0062] After cutting, the strip head continues to travel through the second limiting component 50 to the welding position of the end welding component 60. The control box 70 controls the fifth cylinder 63 in the end welding component 60 to work, driving the first pressure block 62 to move down and squeeze and fix the strip head. At the same time, the seventh cylinder 66 drives the transmission box 67 to move down, thereby driving the welding gun 68 to move down. The third motor 69 works to drive the welding gun 68 to move in the horizontal direction, welding the strip head and tail into one piece, preparing for continuous production of heat exchange tubes.

[0063] Then repeat the above steps to perform the cyclic shearing and end welding operation of the next roll of strip.

[0064] This utility model integrates the guide assembly 20, the first limiting assembly 30, the cutting assembly 40, the second limiting assembly 50, and the end welding assembly 60 onto the same support base 10, and centrally controls them through the control box 70.
