Description
Technical Field
[0001] This utility model relates to the field of high-frequency pipe welding machine technology, specifically a high-frequency pipe welding machine that facilitates pipe connection and fixation. Background Technology
[0002] High-frequency pipe welding machine is a device that uses the electromagnetic characteristics of high-frequency current to weld metal pipes. When welding two metal pipes, this device is needed to connect and fix the ends of the two pipes, and then the high-frequency pipe welding machine is used to weld and fix the connection between the two pipes.
[0003] In the prior art, a high-frequency pipe welding machine with the publication number "CN217991268U" is used to facilitate pipe connection and fixation. The machine uses a motor to drive the connecting seat to move synchronously, making it easy to connect pipes. A rotatable mounting seat limits the pipe and prevents it from shifting during welding. This gives the high-frequency pipe welding machine a quick clamping and limiting structure. With the help of springs, the upper support seat on the high-frequency pipe welding machine can automatically push out and reset.
[0004] However, the above technical solutions and existing technologies have the following drawbacks:
[0005] Although this high-frequency pipe welding machine can clamp and connect two pipes, the process of fixing the pipes requires pressing both sets of upper support seats downwards to their limit positions before rotating the mounting base to limit the pipe position. Furthermore, the inward extension lengths of the two pipes must be adjusted to ensure they are the same before the two sets of support seats move inwards synchronously, precisely aligning the pipe joints directly beneath the high-frequency pipe welding machine. This fixing process is cumbersome and inconvenient. Additionally, the machine can only heat and weld the upper half of the pipe joint, leaving the lower half unwelded, making it unsuitable for practical applications. Utility Model Content
[0006] The purpose of this invention is to provide a high-frequency pipe welding machine that facilitates pipe connection and fixing, so as to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A high-frequency pipe welding machine for easy pipe docking and fixing includes a support base plate, a support back plate, a high-frequency pipe welding machine body, and a heating coil. The support back plate is fixedly connected to the rear side of the upper end face of the support base plate. The high-frequency pipe welding machine body is installed on the upper side of the front end face of the support back plate. A heating coil is provided at the lower end of the high-frequency pipe welding machine body. A first metal pipe is inserted through the right side of the heating coil, and a second metal pipe is inserted through the left side of the heating coil. A support component is provided on the upper end face of the support base plate, and the support component is used to support and limit the first and second metal pipes. A positioning component is provided inside the support component, and the positioning component is used to block and position the first and second metal pipes placed on the support component.
[0009] Preferably, the supporting assembly includes a support column, a support frame, support rollers, limiting rollers, a support shaft, and a support seat. The support column is fixedly connected to the upper end face of the support base plate, and the support frame is fixedly connected to the top of the support column. Multiple support rollers are arranged inside the support frame, and a support shaft is installed inside each of the multiple support rollers. Multiple support seats are symmetrically installed on the front and rear sides of the upper end face of the support frame, and a limiting roller is fixedly connected to the upper end of the support seat.
[0010] Preferably, the positioning component includes a multi-stage electric push rod, a connecting piece, and a positioning stop rod. The positioning stop rod is inserted through the right side of the support frame. The lower end of the positioning stop rod is connected to the connecting piece. The lower end face of the connecting piece is equipped with a multi-stage electric push rod.
[0011] Preferably, a limiting through hole is provided on the right side inside the support frame, and the limiting through hole matches the positioning stop bar. Two sets of positioning stop bars are inserted, and the two sets of positioning stop bars are of the same specification. The distance between the two sets of positioning stop bars is the total length of the first metal pipe plus the second metal pipe.
[0012] Preferably, multiple limiting rollers are fixedly connected, and the multiple limiting rollers have the same specifications. The distance between the front and rear of the multiple limiting rollers is the same as the outer diameter of the first metal pipe and the second metal pipe.
[0013] Preferably, the support roller is a rotatable structure, the support frame is concave in shape, and the multiple support rollers are all at the same height.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. By setting multiple rotatable support rollers, it is convenient for workers to place and connect the first and second metal pipes laterally. By fixing and connecting multiple limiting rollers, it is possible to avoid misalignment caused by forward or backward displacement or shaking during the lateral movement and connection of the first and second metal pipes. During this process, the joint of the first and second metal pipes needs to be in the middle area inside the heating coil so that the high-frequency pipe welding machine body can fully heat and weld the joint of the first and second metal pipes with the help of the heating coil. It has good practicality.
[0016] 2. By controlling the extension of the multi-stage electric push rods on the left and right sides respectively, the multi-stage electric push rods on the left and right sides can drive the positioning stops on the left and right sides to move upward through the connecting plates to block the first metal pipe and the second metal pipe respectively, so as to prevent the joint of the first metal pipe and the second metal pipe from loosening and separating during the subsequent heating and welding process.

[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 Figures 1-4 This utility model provides a technical solution:
[0024] Example 1:
[0025] A high-frequency pipe welding machine for easy pipe connection and fixing includes a support base plate 1, a support back plate 5, a high-frequency pipe welding machine body 6, and a heating coil 8. The support back plate 5 is fixedly connected to the rear side of the upper end face of the support base plate 1. The support back plate 5 is connected to the support base plate 1 by welding. The support back plate 5 can support and fix the high-frequency pipe welding machine body 6. The support base plate 1 is fixed to a designated position on the cement floor by external expansion bolts. The high-frequency pipe welding machine body 6 is installed on the upper side of the front end face of the support back plate 5. The heating coil 8 is provided at the lower end of the high-frequency pipe welding machine body 6. The inner diameter of the heating coil 8 is larger than the outer diameter of the first metal pipe 4 and the second metal pipe 7. The first metal pipe 4 is inserted through the right side of the heating coil 8, and the second metal pipe 7 is inserted through the left side of the heating coil 8. The first metal pipe 4 and the second metal pipe 7 are of the same specifications. When the high-frequency pipe welding machine body 6 is working, it can heat and weld the connection between the first metal pipe 4 and the second metal pipe 7 of the same specifications with the help of the heating coil 8. Since the detailed internal structure and working principle of the high-frequency pipe welding machine body 6 are relatively mature technologies in the prior art, they will not be described in detail here.
[0026] A support component 2 is provided on the upper surface of the support substrate 1. The support component 2 is used to support and limit the first metal pipe 4 and the second metal pipe 7 to prevent the first metal pipe 4 and the second metal pipe 7 from shaking or shifting back and forth during subsequent welding. A positioning component 3 is provided inside the support component 2. The positioning component 3 is used to block and position the first metal pipe 4 and the second metal pipe 7 placed on the support component 2, so that the connection between the first metal pipe 4 and the second metal pipe 7 is more tightly fitted, and to prevent the connection between the first metal pipe 4 and the second metal pipe 7 from loosening and separating during welding.
[0027] Support assembly 2 includes a support column 21, a support frame 22, a support roller 23, a limiting roller 24, a support shaft 25, and a support base 26. The support column 21 is fixedly connected to the upper surface of the support base 1. The support column 21 is connected to both the support base 1 and the support frame 22 by welding. The support column 21 supports and fixes the support frame 22. The support frame 22 is fixedly connected to the top of the support column 21. The support frame 22 is concave in shape. Two sets of support frames 22 are fixedly connected, and both sets have the same specifications and height. The concave support frame 22 does not... It can only support the support shaft 25 and will not come into contact with the first metal pipe 4 and the second metal pipe. Multiple support rollers 23 are provided on the inner side of the support frame 22. The support rollers 23 are rotatable. The multiple rotatable support rollers 23 can not only support the first metal pipe 4 and the second metal pipe 7 respectively, but also make the first metal pipe 4 and the second metal pipe 7 less effort during lateral and left-right movement. The multiple support rollers 23 are all at the same height to avoid vertical misalignment of the first metal pipe 4 and the second metal pipe 7 during docking.
[0028] Each of the multiple support rollers 23 has a support shaft 25 installed inside. The front and rear ends of the support shaft 25 are connected to the support frame 22 by welding. The support shaft 25 not only supports the support rollers 23, but also enables the support rollers 23 to rotate. Multiple support seats 26 are symmetrically installed on the front and rear sides of the upper end of the support frame 22. The support seats 26 are fixed to the upper end of the support frame 22 by screws. The support seats 26 can support and fix the limiting rollers 24. The upper end of the support seat 26 is fixedly connected to the limiting rollers 24. Multiple limiting rollers 24 are fixedly connected, and the multiple limiting rollers 24 are of the same specification. The distance between the front and rear of the multiple limiting rollers 24 is the same as the outer diameter of the first metal pipe 4 and the second metal pipe 7. The multiple limiting rollers 24 can respectively block and limit the first metal pipe 4 and the second metal pipe 7, so as to prevent the first metal pipe 4 and the second metal pipe 7 from shifting or swinging during the docking process.
[0029] Example 2:
[0030] Based on Embodiment 1, in this embodiment, by controlling the extension of the multi-stage electric push rods 31 on the left and right sides respectively, the multi-stage electric push rods 31 on the left and right sides can drive the positioning stop rods 33 on the left and right sides to move upward through the connecting piece 32 to block the first metal pipe 4 and the second metal pipe 7 respectively, so as to prevent the joint of the first metal pipe 4 and the second metal pipe 7 from loosening and separating during the subsequent heating and welding process.
[0031] The positioning component 3 includes a multi-stage electric push rod 31, a connecting piece 32, and a positioning stop rod 33. The positioning stop rod 33 is inserted inside the right side of the support frame 22. There are two sets of positioning stop rods 33, and the two sets of positioning stop rods 33 are of the same specification. The distance between the two sets of positioning stop rods 33 is the total length of the first metal pipe 4 plus the second metal pipe 7. After the two sets of positioning stop rods 33 move upward, they can block and position the first metal pipe 4 and the second metal pipe 7 after docking, so as to prevent the first metal pipe 4 and the second metal pipe 7 from loosening and separating at the docking point, thereby ensuring the stability of the subsequent welding of the first metal pipe 4 and the second metal pipe 7 by the heating coil 8.
[0032] A connecting piece 32 is connected to the lower end of the positioning stop 33. The connecting piece 32 is connected to the positioning stop 33 by welding. The connecting piece 32 can support the positioning stop 33. A multi-stage electric push rod 31 is installed on the lower end face of the connecting piece 32. The upper end of the multi-stage electric push rod 31 is fixed to the lower end face of the connecting piece 32 by screws. The bottom of the multi-stage electric push rod 31 is fixed to the upper end face of the support base plate 1 by screws. Two sets of multi-stage electric push rods 31 are installed, and the two sets of multi-stage electric push rods 31 are of the same specification. Both sets of multi-stage electric push rods 31 are electrically connected to the adjacent external control cabinet through wires. When working, the multi-stage electric push rod 31 can drive the positioning stop rod 33 to rise and fall through the connecting piece 32. Since the internal detailed structure and working principle of the multi-stage electric push rod 31 are relatively mature technologies in the prior art, they will not be described in detail here. A limit through hole 34 is opened on the right side of the support frame 22, and the limit through hole 34 matches the positioning stop rod 33. The limit through hole 34 not only facilitates the up and down movement of the positioning stop rod 33 inside the support frame 22, but also limits the positioning stop rod 33 to prevent it from shaking or deviating during the lifting and lowering process.
[0033] Working principle: The operator first places the first metal pipe 4 and the second metal pipe 7 to be welded flat on multiple support rollers 23. During this process, multiple limiting rollers 24 limit the first metal pipe 4 and the second metal pipe 7 placed on the support rollers 23, preventing them from shifting or wobbling during lateral movement and docking. The rotatable support rollers 23 also make the lateral pushing and docking of the first metal pipe 4 and the second metal pipe 7 less strenuous. After the first metal pipe 4 and the second metal pipe 7 are docked, the operator first controls the extension of the multi-stage electric push rod 31 on the right side, causing the multi-stage electric push rod 31 on the right side to drive the right side through the connecting piece 32. The positioning stop 33 moves upward to block the right end of the first metal pipe 4. Then, one worker assists in pushing the second metal pipe 7 to the right, making the second metal pipe 7 tightly connected with the first metal pipe 4. Another worker controls the extension of the multi-stage electric push rod 31 on the left, so that the multi-stage electric push rod 31 on the left drives the positioning stop 33 on the right to move upward through the connecting piece 32 to block the right end of the first metal pipe 4. This prevents the joint of the first metal pipe 4 and the second metal pipe 7 from loosening and separating during the heating and welding process. At this time, the high-frequency pipe welding machine body 6 can use the heating coil 8 to heat and weld the joint of the first metal pipe 4 and the second metal pipe 7 (see reference). Figure 1 Once the joint is heated and welded to the required state, the high-frequency pipe welding machine body 6 can be stopped. Then, allow the joint between the first metal pipe 4 and the second metal pipe 7 to cool and solidify naturally. At this point, control the retraction of the multi-stage electric push rods 31 on both the left and right sides, which will cause the connecting piece 32 to drive the positioning stops 33 on both sides to descend to the initial position (see reference). Figure 2 This allows workers to pull away the welded first metal pipe 4 and second metal pipe 7 laterally.
[0034] 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.
