Description

Technical Field

[0001] This utility model relates to the field of pipe welding technology, specifically a seamless pipe welding device. Background Technology

[0002] During use, steel pipes often need to be welded together. Butt welding refers to placing the weldment between two clamping devices, aligning their end faces, and welding at the contact point. The cross-sectional dimensions and shape of the weldment at the contact point must be the same to ensure uniform heating of the weldment contact surface.

[0003] For example, Chinese patent application number 201921887559.5 discloses an automatic seamless butt welding device for welded pipes, including a frame. A first motor is installed at one end of the bottom of the frame, and a first threaded rod is driven to the end of the output shaft of the first motor. The first threaded rod is connected to the inner wall of the frame, and sliders are installed on both sides of the first threaded rod. A movable plate is installed in the middle of the frame, and support rods are connected between the movable plate and the two sliders. This utility model achieves one-time welding of the joint by adjusting two second discs to fit with two butt welded pipes, rotating two nuts to squeeze the two second discs and clamp the two butt welded pipes, and rotating the second motor to drive the two butt welded pipes to rotate. The welding effect is good and the welding is convenient. By changing the distance between the third threaded rod and the second threaded rod at the corresponding positions of the two first discs, the joint is always directly below the welding head, which is convenient for welding two butt welded pipes of different lengths.

[0004] However, the pipe butt welding device still has some shortcomings in actual use. For example, it is not equipped with a cooling device, so it cannot be cooled quickly after welding. In the further welding process, the pipe needs to be rotated to weld the entire pipe, which results in low welding efficiency, high labor intensity, and inconvenience. Utility Model Content

[0024] 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.

[0025] like Figure 1-5 As shown, this utility model provides a technical solution: including a machine tool assembly 1, a welding assembly 2 is fixedly installed on the top back of the machine tool assembly 1, and a cooling assembly 3 is installed on the bottom back of the machine tool assembly 1;

[0026] The welding assembly 2 includes a vertical plate 201. A rotating mounting base 202 is fixedly installed on the top front of the vertical plate 201. An arc-shaped transition groove is opened on the front of the rotating mounting base 202. An external gear ring 203 is rotatably installed in the arc-shaped transition groove. A servo motor 204 is fixedly installed on one side of the rotating mounting base 202. One end of the output shaft of the servo motor 204 extends into the rotating mounting base 202, and a gear 205 is fixedly sleeved on the extended end of the output shaft of the servo motor 204.

[0027] The cooling assembly 3 includes a water pump 301. The output end of the water pump 301 is fixedly connected to a main water supply pipe 302. Auxiliary water supply pipes 303 are fixedly connected to the top of both sides of the main water supply pipe 302. A nozzle 304 is fixedly installed at one end of each of the two auxiliary water supply pipes 303. The water pump 301 is fixedly installed at the bottom of the back of the casing 101. The inlet end of the water pump 301 is connected to the bottom of the water storage tank. The water pump 301 delivers the cooling water in the water storage tank to the nozzle 304, and then sprays it from the nozzle 304 to the welding area, thereby improving the cooling efficiency of the welding area and improving the welding completion efficiency.

[0028] In this embodiment, the machine tool assembly 1 includes a chassis 101, a water storage tank is provided inside the chassis 101, an inclined plate 102 is fixedly installed in the middle of the water storage tank, a chip outlet 103 is provided in the middle of one side of the chassis 101, and a collection box 104 is fixedly installed at the bottom of one side of the chassis 101. Waste generated during the welding process will fall onto the fence plate 110 and fall from the fence plate 110 onto the inclined plate 102. Under the action of the inclined plate 102, the waste rolls to the chip outlet 103 and falls from the chip outlet 103 into the collection box 104. A water inlet is provided on one side of the middle of the back of the chassis 101 for filling the water storage tank with water.

[0029] Meanwhile, a baffle plate 105 is fixedly installed on the four edges of the top surface of the chassis 101, and two linear motors 106 are fixedly embedded in the top front of the chassis 101. An L-shaped support plate 107 is fixedly installed on the front of the slider of each of the two linear motors 106.

[0030] Mounting plates 108 are fixedly installed on the bottom surface of the horizontal portions of the two L-shaped support plates 107, and chucks 109 are fixedly installed on the opposite sides of the two mounting plates 108. A fence plate 110 is provided on the top surface of the chassis 101.

[0031] The upright plate 201 is fixedly installed on the top of the back of the chassis 101.

[0032] The gear 205 meshes with the external gear ring 203. A cylinder 206 is fixedly installed on the inner ring surface of the external gear ring 203. A welding gun 207 is fixedly installed on one end of the piston rod of the cylinder 206. The rotation of the external gear ring 203 can drive the welding gun 207 to rotate. The rotation of the welding gun 207 can quickly perform rotational welding on the welding joint of the two steel pipes. There is no need for manual rotation to the steel pipe or manual operation of the welding gun 207 for welding, resulting in higher welding efficiency.

[0033] Support rods 208 are fixedly installed on the top of both sides of the upright plate 201, and the nozzles 304 are respectively fixedly embedded in the rods of the two support rods 208.

[0034] In use, one end of each of the two steel pipes to be welded is placed in one of the two chucks 109, and then the chucks 109 clamp the end of the steel pipe. Next, two linear motors 106 are activated, which control the movement of two L-shaped support plates 107. The movement of the L-shaped support plates 107 moves the mounting plate 108 and the chucks 109. The movement of the two chucks 109 allows the two steel pipes to quickly approach each other and align their welding surfaces. Then, the cylinder 206 is activated, and under the action of the cylinder 206, the welding gun 207 moves to the welding position. After aligning the welding point, welding is performed using the welding gun 207. Simultaneously, the servo motor 204 can be activated. Under the action of the servo motor 204, the gear 205 located in the cavity of the rotating mounting base 202 will rotate. The rotation of the gear 205 will drive the outer gear ring 203 to rotate, which in turn drives the welding gun 207 to rotate. The rotation of the welding gun 207 can quickly rotate and weld the two steel pipes at the welding point, eliminating the need for manual rotation of the steel pipes or manual operation of the welding gun 207, thus improving welding efficiency.

[0035] Waste generated during the welding process falls onto the fence plate 110 and then onto the inclined plate 102. Under the action of the inclined plate 102, the waste rolls to the chip outlet 103 and falls into the collection box 104.

[0036] Furthermore, after welding is completed, in order to improve the cooling efficiency of the weld, water cooling methods can be used after a short wait, including directly pouring water onto the weld surface and using cold water for cooling. Cold water with a temperature below 40 degrees Celsius should be used, and the flow rate should be greater than the rated flow rate of the weld to ensure the cooling effect. When water cooling is applied, the cooling water flowing from the nozzle 304 should maintain a stable flow. The cooling water in the water storage tank can be transported to the nozzle 304 by the water pump 301. At the same time, water cooling is only applied to the steel materials that are suitable for water cooling. Then, the water is sprayed from the nozzle 304 onto the weld to improve the cooling efficiency of the weld and improve the welding completion efficiency.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
