Description

Technical Field

[0001] This utility model relates to the field of high-frequency welded pipe machine technology, and in particular to a weld scar collection structure and a high-frequency welded pipe machine. Background Technology

[0002] High-frequency pipe welding machine, as a high-efficiency metal pipe forming equipment, is based on the skin effect and proximity effect generated by high-frequency current at the edge of the pipe blank. It achieves pressure welding by melting the metal contact surface through instantaneous high temperature, and simultaneously completes the forming and joint curing.

[0003] The Chinese Patent Database has published a patent titled "A Weld Scar Removal Device for a High-Frequency Welded Pipe Unit," with publication (announcement) number CN219211860U and publication (announcement) date of June 20, 2023. Section

[0041] of its specification discloses: [Example 1] Figure 1 As shown, the weld scar removal assembly 3 also includes: a mounting base 303, which is connected to the frame 4. The mounting base 303 is connected to two weld scar removal assemblies 3 that are spaced apart along the direction of weld pipe movement. A tray 304 connected to the mounting base 303 is provided below the weld scar removal assembly 3. The tray 304 is used to hold the shavings scraped off by the blade and prevent the shavings from falling onto the frame 4.

[0004] The shortcomings of the above technical solution are that although the tray can collect debris, it is necessary to manually clean the debris in the tray regularly during long-term use. Since the tray is fixedly connected to the mounting base, manual cleaning is relatively laborious. In addition, the upper edge of the tray has a protruding edge, which further increases the inconvenience of cleaning. During the process of cleaning debris outward, there is a possibility that the debris may fall onto the frame. Utility Model Content

[0005] This application provides a weld spatter collection structure. By designing the tray as a detachable structure, it facilitates manual removal and cleaning, improving cleaning convenience and preventing iron filings from falling onto the machine frame. This application also discloses a high-frequency pipe welding machine.

[0006] The first aspect of this application provides a weld spatter collection structure, comprising:

[0007] A fixed plate, which is connected to the frame of the high-frequency welded pipe machine;

[0008] A collection tray, which is disposed on the fixed tray, is used to collect fallen weld spatter;

[0009] A positioning mechanism is connected to the fixed plate, and the positioning mechanism is used to detachably position the collection plate on the fixed plate;

[0010] The fixed disk has a positioning groove at its lower end, and the collection disk has a positioning block on its outer periphery. The positioning block is inserted into the positioning groove, and the positioning mechanism is connected to the lower end of the fixed disk and is used to position the positioning block in the positioning groove.

[0011] The positioning mechanism includes: a positioning post, which is threadedly connected to the bottom of the fixed plate, and the upper end of the positioning post is a limiting end, which is used to limit the positioning block in the positioning groove.

[0012] The positioning mechanism further includes an anti-loosening component, which is connected to the positioning post and is used to improve the stability of the positioning post connection.

[0013] The positioning mechanism further includes: a pin shaft connected to the fixed disk, and a positioning column rotatably connected to the pin shaft around the pin shaft.

[0014] The beneficial effects of the above embodiments are as follows: by setting a positioning mechanism to detachably position the collection tray on the fixed tray, when there are many weld spatters in the collection tray, the collection tray can be directly removed for cleaning or directly rinsed with water, which improves the convenience of cleaning and can prevent weld spatters from falling onto the frame.

[0015] A second aspect of this application provides a high-frequency pipe welding machine, including the aforementioned weld scar collection structure. Attached Figure Description

[0022] Example 1

[0023] like Figure 1 As shown, a weld spatter collection structure includes: a fixed plate 1, a collection plate 2, and a positioning mechanism 3. The fixed plate 1 is connected to the frame of a high-frequency welded pipe machine, specifically to the mounting base of a weld spatter removal device. The collection plate 2 is disposed on the fixed plate 1 and is used to collect fallen weld spatter. The positioning mechanism 3 is connected to the fixed plate 1 and is used to detachably position the collection plate 2 on the fixed plate 1.

[0024] This embodiment is an improvement on the weld scar removal device of the high-frequency welded pipe unit with publication number CN219211860U. The improvement is only made to the tray for collecting weld scars, which is made into a separate detachable structure.

[0025] Specifically, such as Figure 1 As shown, the fixed plate 1 is connected to the mounting base by bolts or welding. The fixed plate 1 is a quadrilateral hollow structure. The collecting plate 2 is installed in the hollow structure. The size of the collecting plate 2 is at least enough to cover the area where the weld spatter falls. The collecting plate 2 is made of sheet metal with a thickness between 0.5mm and 1mm to reduce the weight of the collecting plate 2 and make it easier to move the collecting plate 2 manually.

[0026] Specifically, such as Figure 1 As shown, a positioning groove 101 is provided at the lower end of the fixed disk 1, and a positioning block 201 is arranged on the outer periphery of the collecting disk 2. The positioning block 201 is inserted into the positioning groove 101. The positioning mechanism 3 is connected to the lower end of the fixed disk 1 and is used to position the positioning block 201 in the positioning groove 101. By designing the positioning structure to be hidden under the fixed disk 1, weld spatter is prevented from falling onto the positioning structure.

[0027] Specifically, such as Figure 1 As shown, the material collection tray 2 is equipped with positioning blocks 201 on at least two sides, and the middle part of the material collection tray 2 is a material collection area that is larger at the top and smaller at the bottom.

[0028] Specifically, such as Figure 1 As shown, the positioning mechanism 3 includes a positioning post 301, which is threadedly connected to the bottom of the fixed plate 1. The upper end of the positioning post 301 is a limiting end, which is used to limit the positioning block 201 in the positioning groove 101. The position of the positioning post 301 can be easily adjusted through the threaded structure.

[0029] Specifically, such as Figure 1 As shown, an L-shaped bracket 302 is connected to the lower end of the fixed plate 1. The vertical side of the bracket 302 is connected to the bottom surface of the fixed plate 1. A threaded hole is opened on the horizontal side of the bracket 302. The positioning post 301 has a threaded section and is threadedly connected to the positioning post 301 through the threaded section. The limiting end of the upper end of the positioning post 301 is a disc-shaped structure. The diameter of the disc-shaped structure is larger than the width of the positioning block 201. The end of the positioning post 301 extending below the bracket 302 has a square (such as a square, a regular hexagon, etc.) block. The block facilitates the rotation of the positioning post 301 by a wrench.

[0030] Specifically, such as Figure 1 As shown, the positioning mechanism 3 further includes an anti-loosening component 303, which is connected to the positioning post 301. The anti-loosening component 303 is used to improve the stability of the connection of the positioning post 301. The anti-loosening component 303 is a nut. The positioning stability of the positioning post 301 is improved by the anti-loosening component 303, thereby improving the positioning stability of the material collection tray 2.

[0031] When using this weld spatter collection structure, the rotating positioning column 301 confines the positioning block 201 in the positioning groove 101, and the collecting tray 2 collects the fallen weld spatter. When the machine stops, the positioning column 301 is rotated so that the positioning column 301 moves downward, thereby separating the positioning block 201 from the positioning groove 101, and the collecting tray 2 is taken out from under the fixed tray 1. The weld spatter can be cleaned out by tilting, sweeping, or rinsing. Then the positioning block 201 is placed in the positioning groove 101, and the positioning column 301 is rotated to position the positioning block 201, thereby completing the cleaning operation of the collecting tray 2.

[0032] Because the collection tray 2 and the fixed tray 1 are designed to be detachable, the operator can remove the collection tray 2 from the fixed tray 1 for cleaning. After the collection tray 2 is removed, the welding slag can be cleaned out by pouring, rinsing, sweeping, etc. In the original structure, the collection tray 2 is above the frame and is a certain height from the ground, so it is not convenient to clean the welding slag. This split and detachable structure expands the ways to clean the welding slag and also prevents the welding slag from falling onto the frame, thus having high ease of use.

[0033] Example 2

[0034] Example 2 is an improvement on Example 1, such as... Figure 2 As shown, the positioning mechanism 3 further includes a pin 304, which is connected to the fixed disk 1. The positioning post 301 is rotatably connected to the pin 304 around the pin 304. Through the rotational connection, the positioning post 301 can be easily moved away from under the positioning block 201, thereby improving the convenience of picking up or assembling the material collection tray 2.

[0035] Specifically, such as Figure 2 As shown, the vertical side of the bracket 302 has a connecting hole. One end of the pin 304 passes through the connecting hole and is inserted into the corresponding through hole of the fixed plate 1. The upper end of the pin 304 is fixedly connected to the fixed plate 1 by bolts. The lower end of the pin 304 has a limiting block, which limits the bracket 302 to the lower end of the fixed plate 1. The pin 304 only plays a limiting role here. That is, after applying external force manually, the bracket 302 can rotate at the lower end of the fixed plate 1. When the positioning column 301 is rotated away from the positioning block 201, the collection plate 2 can be removed. When the positioning block 201 is placed in the positioning groove 101, the bracket 302 is rotated so that the positioning column 301 moves to the lower end of the positioning block 201, thus limiting the positioning block 201 in the positioning groove 101, thereby improving the usability of this weld scar collection structure.
