Description

Technical Field

[0001] The invention relates to the technical field of building steel bar welding equipment, in particular to a fully automatic welding machine for steel mesh. Background Art

[0002] Steel mesh is a mesh with longitudinal and transverse bars arranged at regular intervals and at right angles to each other, with all intersections welded together. Steel mesh can significantly improve the quality of reinforcement projects, speed up construction, and enhance the crack resistance of concrete, offering excellent overall economic benefits.

[0003] During the production process of the steel cage, a full-coverage steel mesh needs to be tied or welded to the top and bottom of the steel cage. Its function is to effectively prevent the mold expansion phenomenon when grouting the steel cage. The current method can only be done by manual tying, which is more troublesome.

[0004] At present, there are two methods for making steel mesh: fully manual binding and fully automatic welding equipment. The disadvantages of fully manual binding are: fully manual operation, manual lifting of steel bars to pre-arrange them into finished product intervals, high manpower requirements, large space occupation, and low efficiency; operators work in a squatting position, which is labor-intensive. How to reduce labor costs while ensuring work efficiency is a technical problem that needs to be solved; and although fully automatic welding equipment has solved the problem of manual labor intensity, most of the fully automatic welding equipment is purchased imported equipment, which is extremely expensive, occupies a large space, and has high requirements for related supporting facilities, so it is necessary to accelerate the pace of independent research and development in my country; and the steel mesh welding equipment currently on the market can only handle the welding of single-layer welds due to structural limitations, and cannot meet the needs of simultaneous automated welding of multiple welds. For example, if the upper and lower layers of steel mesh on the steel cage can be welded at the same time, the overall work efficiency can be further improved. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The present invention has a simple structure. The mesh welding mechanism is inclined to the upper and lower frames, so that the mesh welding mechanism can increase the welding contact surface between the steel mesh and the steel frame when it is close to the welding surface. The welding point position and the initial position are completed by a linear motion, thereby avoiding position interference, thereby reducing the position error of the welding and improving the accuracy of the welding. It also allows multiple mesh welding mechanisms to be arranged simultaneously on the welding axis.

[0017] (2) The present invention drives the entire upper welding head and the lower welding head to be inserted into the interior of the steel frame through the oblique linear guide rail, the lower electrode cylinder extends, and the upper electrode cylinder retracts, pressing the welding point of the steel bar to be welded between the upper welding head and the lower welding head, and the transformer energizes the entire upper electrode assembly and the lower electrode assembly to realize the welding work. After the welding is completed, the upper electrode cylinder retracts and the lower electrode cylinder retracts, and the upper electrode assembly and the lower electrode assembly return to the origin under the drive of the oblique linear guide rail. During the working process, the upper welding head and the lower welding head compact the three layers of materials at the welding point (respectively, the transverse reinforcement on the steel frame, the additional reinforcement and the transverse reinforcement on the steel mesh) through the action of the upper electrode cylinder and the lower electrode cylinder respectively, and the whole is energized to a suitable current. At this time, the transverse reinforcement on the steel mesh will be quickly melted due to its small diameter, and the upper and lower welding joints are driven by the upper and lower electrode cylinders respectively. After the transverse reinforcement on the steel mesh is quickly melted, the upper and lower welding joints will continue to be pressed tightly, and the power is continued to be supplied. The transverse reinforcement on the steel frame, the additional reinforcement and the transverse reinforcement on the steel mesh are fusion-welded to complete the welding. The present invention completes two actions (fusing the transverse reinforcement on the steel mesh and fusion-welding the additional reinforcement and the transverse reinforcement on the steel frame) by one power supply, realizing welding between three layers of objects. The entire welding action is simple and smooth. The present invention can realize automated production as a whole, greatly reducing the labor intensity and number of workers, which is conducive to reducing the labor cost of the enterprise, and greatly improving production efficiency and safety factor.

[0018] (3) The present invention provides relative mesh welding mechanisms on both the upper frame and the lower frame, so that four mesh welding mechanisms can work simultaneously, thereby accelerating the welding progress of the steel mesh and the steel frame, and realizing double-layer simultaneous welding;

[0019] (4) The present invention can adapt to the changes in height, length, longitudinal spacing, transverse spacing, and diameter of welded steel bars of various specifications of steel frames and steel meshes by setting a lifting component and an X-axis moving component. It has wide applicability and high economic value. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The lower frame 1 is fixedly connected to the ground, and mesh welding mechanisms 2 are installed obliquely on both sides of the lower frame 1. Lifting components 3 are fixedly provided at both ends of the lower frame 1. The upper end of the lifting component 3 is fixedly connected to the upper frame 4. Mesh welding mechanisms 2 are installed obliquely on both sides of the upper frame 4. Figure 2 and Figure 15 As shown, this inclined setting method allows the upper welding head 2043 and the lower welding head 2053 to enter obliquely from the space between the steel mesh 19 and the steel frame 17, and can increase the welding contact area between the steel mesh 19 and the steel frame 17 when close to the welding surface. The round trip between the welding point position and the initial position is completed through a linear motion, avoiding position interference, thereby reducing the position error of the welding, improving the accuracy of the welding, and allowing multiple mesh welding mechanisms 2 to be arranged simultaneously on the welding axis.

[0040] The left side of the lower frame 1 and the upper frame 4 are both provided with an X-direction moving component 5, which is slidably connected to the mesh welding mechanism 2. Figure 1 As shown, the mesh welding mechanism 2 on the left can slide on the X-axis moving component 5. This setting is used to adjust the width of the steel frame 17 and the steel mesh 19. A support frame 6 is also installed on the lower frame 1, and the support frame 6 is used to limit the lateral deviation of the steel frame 17 when moving.

[0041] The mesh welding mechanism 2 includes a bottom inclined plate 201, a mounting plate 202, a transformer 203, an upper electrode assembly 204, a lower electrode assembly 205 and a mounting frame 206. The bottom inclined plate 201 is fixedly arranged on the X-direction moving assembly 5. The mounting plate 202 is slidably connected to the bottom inclined plate 201 through a sliding member. The transformer 203 is fixed on the mounting plate 202. The output end of the transformer 203 is fixedly connected to the upper electrode assembly 204 and the lower electrode assembly 205 respectively; the mounting plate 202 is integrally welded to the mounting frame 206. Figure 5 and Figure 6 As shown, reinforcing ribs 11 are fixed on the mounting frame 206. This embodiment provides two installation methods of the reinforcing ribs 11. The structure of the reinforcing ribs 11 is not an improved part of the present invention, so it is not described in detail; the upper electrode assembly 204 and the lower electrode assembly 205 are fixed on the mounting frame 206.

[0042] The upper electrode assembly 204 includes a hard copper busbar 2041, a soft copper busbar 2042, an upper welding head 2043, a hard copper busbar 2044, an insulating assembly and an upper electrode cylinder 2045. The output end of the transformer 203 is fixedly connected to the hard copper busbar 2041. The soft copper busbar 2042 is fixedly installed on the hard copper busbar 2041. One end of the soft copper busbar 2042 is fixedly connected to the hard copper busbar 2044. The upper end of the hard copper busbar 2044 is provided with an upper welding head 2043. The hard copper busbar 2044 is fixedly connected to the output end of the upper electrode cylinder 2045 through an insulating fixing assembly. The upper electrode cylinder 2045 is fixedly mounted on the mounting frame 206.

[0043] The lower electrode assembly 205 includes a hard copper busbar 3 2051, a soft copper busbar 2052, a lower welding head 2053, a hard copper busbar 4 2054, an insulating assembly and a lower electrode cylinder 2055. The output end of the transformer 203 is fixedly connected to the hard copper busbar 3 2051. The soft copper busbar 2052 is fixedly provided on the hard copper busbar 3 2051. One end of the soft copper busbar 2052 is fixedly connected to the hard copper busbar 4 2054. The upper end of the hard copper busbar 4 2054 is provided with a lower welding head 2053. The hard copper busbar 4 2054 is fixedly connected to the output end of the lower electrode cylinder 2055 through an insulating fixing assembly. The lower electrode cylinder 2055 is fixedly provided on the mounting frame 206.

[0044] The working principle of the mesh welding mechanism 2 is as follows: during operation, the upper welding head 2043 and the lower welding head 2053 will not contact each other. In order to avoid interference in movement and protect the stability of the upper welding head 2043 and the lower welding head 2053, the oblique linear guide 12 is driven by the oblique cylinder 13, driving the entire upper welding head 2043 and the lower welding head 2053 to be inserted into the interior of the steel frame 17, the lower electrode cylinder 2055 is extended, and the upper electrode cylinder 2045 is retracted, and the steel mesh 19 to be welded and the additional ribs 18 (usually on both sides of the steel frame 17 during production) are welded. Additional ribs 18 are added between the steel mesh 19 for welding. The welding points between the additional ribs 18 (the steel bar diameter of the additional ribs 18 is larger than the steel bar diameter of the steel mesh 19 and smaller than the steel bar diameter of the steel frame 17) are pressed between the upper welding head 2043 and the lower welding head 2053. The transformer 203 energizes the entire upper electrode assembly 204 and the lower electrode assembly 205 to realize the welding work. After the welding is completed, the upper electrode cylinder 2045 and the lower electrode cylinder 2055 are retracted, and the upper electrode assembly 204 and the lower electrode assembly 205 are returned to the origin under the drive of the oblique linear guide 12. During the working process, the upper welding head 2043 and the lower welding head 2053 compact the three layers of materials at the welding point (the transverse reinforcement on the steel frame 17, the additional reinforcement 18 and the transverse reinforcement on the steel mesh 19) through the upper electrode cylinder 2045 and the lower electrode cylinder 2055 respectively, and the whole is energized to a suitable current. At this time, the transverse reinforcement on the steel mesh 19 will be quickly fused due to its small diameter, and the upper welding head 2043 and the lower welding head 2053 are driven by the upper electrode cylinder 2045 and the lower electrode cylinder 2055 respectively. After the transverse reinforcement on the steel mesh 19 is quickly fused, the upper welding head 2043 and the lower welding head 2053 are The welding heads 2053 will continue to be pressed together, and power will continue to be supplied. The transverse bars on the steel frame 17, the additional bars 18 and the transverse bars on the steel mesh 19 will be fused and welded to complete the welding. In this embodiment, two actions (melting of the transverse bars on the steel mesh 19 and fusion welding of the additional bars 18 and the transverse bars on the steel frame 17) can be completed by powering on once during operation, thereby realizing welding between three layers of objects. The entire welding action is simple and smooth, and the entire mesh welding mechanism 2 can realize automated production as a whole, greatly reducing the labor intensity and number of workers, which is beneficial to reducing the labor cost of the enterprise, and greatly improving production efficiency and safety factor.

[0045] In this embodiment, since the mesh welding mechanism 2 provided on the upper frame 4 welds the upper steel mesh 19 and the additional ribs 18, the output ends of the upper electrode cylinder 2045 and the lower electrode cylinder 2035 are facing downward, so the soft copper bus 1 2042 and the soft copper bus 2 2052 of the mesh welding mechanism 2 installed on the upper frame 4 are multi-piece fixed and fitted extensions (without contact with the upper electrode cylinder 2405 and the lower electrode cylinder 2035 to avoid electrical interference). This method is an appropriate adjustment made according to the actual production method. The whole is still composed of the soft copper bus 1 2042 connected to the hard copper bus 1 2041 and the hard copper bus 2 2044 respectively, and the soft copper bus 2 2052 connected to the hard copper bus 3 2051 and the hard copper bus 4 2054 respectively. It is not a structural innovation, so the present invention does not make distinguishing marks on the mesh welding mechanisms 2 respectively provided on the upper frame 4 and the lower frame 1.

[0046] The lifting assembly 3 includes a lifting frame 301, an electric cylinder 302, a guide rail, a linear bearing 304 and a guide plate 305. The lifting frames 301 are fixedly installed on both sides of the lower frame 1. The electric cylinder 302 is fixed in the lifting frame 301. The output shaft 306 of the electric cylinder 302 passes through the lower frame 1 and is fixedly connected to the upper frame 4. Guide rods 303 are provided on both sides of the electric cylinder 302. The upper end of the guide rod 303 is fixedly connected to the upper frame 4. The connection between the guide rod 303 and the lower frame 1 is sleeved with a linear bearing 304; the top of the lifting frame 301 is provided with The guide plate 305 and the setting of the guide plate 305 will prevent the upper end of the guide rod 303 from contacting the linear bearing 304 during the process of retraction and descent of the output shaft 306, so as to avoid damaging the linear bearing 304. The setting of the guide plate 305 can also assist in the lifting height of the positioning electric cylinder 302 and provide a certain support for the descending upper frame 4. The output height of the output shaft 306 of the electric cylinder 302 is used to adapt to the specification adjustment of the height direction and the specification adjustment of the width direction of the steel frame 17 and the support of the welding assembly.

[0047] In this embodiment, by arranging the cooperation of the lifting component 3 and the X-direction moving component 5, it can adapt to the changes in the height, length, longitudinal spacing, transverse spacing, and welded steel bar diameter of various specifications of steel bar frames and steel bar meshes, and has wide applicability and high economic value.

[0048] The insulating fixing assembly includes an upper insulating gasket 7, an avoidance hole 8, an insulating hollow column 9, a lower insulating gasket 10 and a bolt 11. The same avoidance hole 8 is opened on the hard copper busbar 2044 and the hard copper busbar 4 2054. The upper end of the avoidance hole 8 is affixed to the upper insulating gasket 7, and the inside of the avoidance hole 8 is provided with an insulating hollow column 9. The bottom of the insulating hollow column 9 is connected to the lower insulating sheet. The bolt 11 passes through the upper insulating gasket 7, the insulating hollow column 9 and the lower insulating gasket 10 in sequence, and the lower end of the bolt 11 extends into the output end of the upper electrode cylinder 2045 or the lower electrode cylinder 2055 and is screwed and fixed.

[0049] The sliding member is an oblique linear guide 12, the upper end of which is slidably connected to the mounting plate 202. A solenoid valve assembly 14 is also mounted on the mounting plate 202 and electrically connected to the oblique linear guide 12. The solenoid valve assembly 14 senses the range of motion of the mounting plate 202 on the oblique linear guide 12, and promptly senses and indicates the range of motion of the upper electrode assembly 204 and the lower electrode assembly 205 driven by the mounting plate 202.

[0050] The outer cover of the solenoid valve assembly 14 is provided with a dustproof box 15 to protect the solenoid valve assembly 15 from dust interference.

[0051] There are two support frames 6 , which are respectively arranged on the left and right sides of the lower frame 1 , and the support frame 6 on the left is slidably connected to the X-direction moving component 5 .

[0052] The working principle of the present invention is as follows: first, the mesh welding mechanism 2 on the left side is moved to the far left by the X-direction moving assembly 3, and the steel frame 17 and the steel mesh 19 are both transported to the welding position. The support frame 6 is used to limit the lateral deviation of the steel frame 17 during movement. Then, the X-direction moving assembly 3 drives the mesh welding mechanism 2 on the left side to move right to the left welding position of the steel frame 17 and the steel mesh 19, and prepares for welding.

[0053] As shown in the figure, the four mesh welding mechanisms 2 can perform welding at the same time when the current conditions are good, and achieve the welding work of the required welding points; if the current conditions are average, the four mesh welding mechanisms 2 can perform welding work in turn, and achieve the welding work of the required welding points. Finally, the mesh welding mechanism 2 returns to the origin driven by the oblique linear guide rail 12, waiting for the next welding instruction.

[0054] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of rights of the present invention. Therefore, modifications, equivalent changes, improvements, etc. made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
