Description

Technical Field

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

[0002] Steel pipe welding refers to the process of bending and deforming steel strips or plates into shapes such as circles and squares, and then welding them together to form steel pipes with seams on the surface. The raw materials used for welding steel pipes are steel plates or strips. Currently, steel pipe welding is generally carried out by manual feeding.

[0003] A search revealed, for example, a utility model patent with Chinese publication number CN220427258U, which discloses a feeding device for steel pipe welding. This device uses a lifting trough to provide space for the receiving pipe groove to descend. A hydraulic cylinder controls the descent of the receiving pipe groove into the lifting trough, allowing the steel pipe to be welded to fall into the receiving pipe groove under gravity. A telescopic plate, based on a telescopic base, allows for easy extension and retraction of the pusher assembly, adapting to different steel pipe lengths and preventing the pusher assembly from obstructing the placement of the steel pipe. A lifting block drives the pusher base to adapt to the height of steel pipes with different diameters, avoiding the inability to reach the sides of the steel pipe to be welded due to a fixed pusher height. An electric telescopic rod pushes the steel pipe to be welded into the welding device's feed inlet. A discharge ramp facilitates the placement of multiple sets of steel pipes, reducing the need for frequent feeding operations.

[0004] However, the above devices do not have any protective structures along the movement path of the steel pipes during the feeding process. Therefore, the steel pipes are very prone to tilting during the feeding process, which can cause them to fall outside the device, affecting normal feeding and damaging the quality of the steel pipes. Therefore, a feeding device for steel pipe welding is proposed to solve the above problems. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-3 This embodiment of a feeding device for steel pipe welding includes a feeding base 1, a receiving groove 2 on the top wall of the feeding base 1, a material receiving pipe groove 3 in the receiving groove 2, and a material storage and conveying mechanism 4 on the feeding base 1. In use, this device is used in conjunction with the main body of the steel pipe welding mechanism to transport the feeding base 1 to one side of the feed inlet of the steel pipe welding device so that the center points of the feeds of the two are consistent. The material receiving pipe groove 3 is adjusted to be at the same level as the steel pipe welding clamping mechanism, so that the device can push the steel pipe to be welded into the clamping mechanism in the horizontal direction for subsequent operations.

[0024] Specifically, the material conveying mechanism 4 includes a mounting plate 401. The mounting plate 401 is fixedly mounted on the top of the feeding base 1. A hydraulic push rod 402 is mounted on the mounting plate 401. A feeding push plate 403 is mounted on the free end of the hydraulic push rod 402. A feeding chute 404 is formed on the top wall of the feeding base 1. A storage plate 405 is hinged to the feeding chute 404. A mounting frame 406 is mounted on the top of the feeding base 1. A mounting groove 407 is formed on the bottom wall of the mounting frame 406. A motor 408 is mounted on the inner top wall of the mounting groove 407. A threaded rod 409 is rotatably connected inside the mounting groove 407. A threaded seat 410 is threadedly connected to the outside of the threaded rod 409. A pulley 411 is mounted on the outside of the threaded rod 409. The two pulleys 411 transmit power between each other. A belt 412 is connected to the bottom of the threaded seat 410, and a hinge block 413 is hinged to it. By setting up a material storage and conveying mechanism 4, steel pipe materials can be placed on a horizontal storage plate 405. When it is necessary to feed the steel pipe materials, it is only necessary to control the motor 408 to drive the two threaded rods 409 to rotate simultaneously, and drive the two threaded seats 410 to move downwards simultaneously, gradually causing the storage plate 405 to rotate downwards and tilt. The steel pipe materials on the storage plate 405 gradually roll into the feeding chute 404. The feeding chute 404 is located inside the feeding base 1, so there will be no rolling phenomenon. The steel pipe materials will roll along the feeding chute 404 into the receiving pipe groove 3 to complete the next feeding work. Compared with the comparative device, this feeding method is safer.

[0025] Specifically, the top wall of the storage plate 405 has two sliding grooves, and a slider is slidably connected inside the groove. When the threaded seat 410 drives the storage plate 405 to rotate up and down, the slider will slide in the groove to adapt to the changes of the storage plate 405.

[0026] Specifically, the lowest point of the feeding chute 404 and the highest point of the receiving trough 2 are on the same horizontal line. Several rubber deceleration strips are installed on the feeding chute 404. The rubber deceleration strips can slow down the rolling speed of the steel pipe and allow the steel pipe to safely enter the receiving trough 3.

[0027] Specifically, a control panel is provided at one end of the feeding base 1, and four support columns are installed at the bottom of the feeding base 1. A baffle is installed on one side of the top wall of the feeding base 1. The baffle is located at the top side of the receiving groove 2 and can prevent the rolling steel pipe from rolling out of the receiving pipe groove 3.

[0028] When implementing this procedure, please follow these steps:

[0029] 1) First, make the storage plate 405 horizontal, and place the steel pipe preparation on the feeding base 1 and storage plate 405 near the mounting plate 401. When feeding is required, control the motor 408 to drive the two threaded rods 409 to rotate simultaneously.

[0030] 2) Then the two threaded seats 410 move downwards at the same time, gradually causing the storage plate 405 to rotate and tilt downwards, and the steel pipes on the storage plate 405 gradually roll into the feeding chute 404.

[0031] 3) Finally, the steel pipe will roll along the feeding chute 404 into the receiving pipe groove 3, and then the feeding electric push rod 6 will be controlled to push the steel pipe in the receiving pipe groove 3 into the steel pipe welding device for welding.

[0032] In summary, this steel pipe welding feeding device, by setting up a material storage and conveying mechanism 4, can place steel pipe blanks on a horizontally positioned storage plate 405. When it is necessary to feed the steel pipe blanks, it is only necessary to control the motor 408 to drive the two threaded rods 409 to rotate simultaneously, and drive the two threaded seats 410 to move downwards simultaneously, gradually causing the storage plate 405 to rotate downwards and tilt. The steel pipe blanks on the storage plate 405 gradually roll into the feeding chute 404. The feeding chute 404 is located inside the feeding base 1, so there will be no rolling phenomenon. The steel pipe blanks will roll along the feeding chute 404 to the receiving pipe groove 3 to complete the next feeding work. Compared with the comparative device, this feeding method is safer.
