Description

Technical Field

[0001] The invention relates to the technical field of welding, in particular to a light steel keel connection spot welding forming machine. Background Art

[0002] Lightweight steel keels are mainly made of high-quality hot-dip galvanized plates rolled through a cold-bending process. They are metal frames used for construction and decoration. This material has the advantages of light weight, high strength, fire resistance, moisture resistance, and easy processing. Therefore, it is widely used in suspended ceilings, partition walls, floor paving and other fields.

[0003] In the prior art, spot welding machines are often used to spot weld the connection positions of light steel keels. During welding, pressure is applied through the upper and lower electrodes, and low voltage and high current are passed instantly, so that the electrode pressure position is partially melted to form fusion. During the welding process, the surface of the weldment is first cleaned, and then the welded sheets are overlapped and assembled, pressed between two columnar copper electrodes, and a clamping force is applied. When a sufficiently large current passes, a large amount of resistance heat is generated at the contact point of the keel, and the hottest metal in the center area is quickly heated to a plastic state to form a lens-shaped liquid molten pool. The voltage is continued to be maintained, the current is disconnected, and a weld point is formed after the metal cools.

[0004] The current light steel keel spot welding forming machine has the following problems: the light steel keel is an important component of the frame, and the strength and uniformity of its connection points are directly related to the stability of the entire structure. The current spot welding machine is handheld by the operator. Due to the limited stability of human hands, it is difficult to ensure that the spacing between each welding point is completely consistent. The uneven spacing of the spot welding positions will directly affect the strength of the keel connection, resulting in insufficient bearing capacity, and it is easy to loosen or break when subjected to external force or load; when the spot welding machine of the prior art is used, the operator needs to use one hand to position the light steel keel during the spot welding process and use the other hand to perform the spot welding operation. The operational stability of using the hand to stabilize the keel to be connected is insufficient, and it is impossible to ensure that the two keels are in close contact, which will reduce the welding quality.

When the push rod 319 does not push the rack plate 318, the spring between the rack plate 318 and the upper outer frame plate 31 will release the stored force to push the rack plate 318, the push rod 319 and the disengagement button 320 back to their original positions. Fig.14 In the position shown in FIG. 1 , the rack plate 318 is restricted in the slide groove of the upper outer frame plate 31 and can only slide left and right.

[0043] Working principle: Before use, by loosening the limit bolt button 212, the side guide block 211 can slide on the light rod 210, so that the vertical keel pieces 12 of different widths can be adaptively adjusted. After adjusting to the appropriate position, the limit bolt button 212 is tightened to complete the locking of the position of the side guide block 211. During use, first place the vertical keel piece 12 and the L-shaped keel 11 to be connected to the specified position according to construction requirements, and then move the spot welding forming machine from the right side of the angle formed by the L-shaped keel 11 and the vertical keel piece 12 from bottom to top, so that the fixed extrusion plate 27 is in contact with the side of the L-shaped keel 11, and the fixed extrusion plate 27 is in a plane position of the spot welding connection, and then pinch the movable pull ring 24 in the keel clamping component group 02, The specific holding method is that the operator's right palm and thumb are in contact with the grip plate 23, and the other four fingers hook the movable pull ring 24, and the movable pull ring 24 is pulled toward the grip plate 23 by hooking the fingers. As the movable pull ring 24 moves, the tension spring between the movable pull ring 24 and the back plate 25 will accumulate force and stretch, and the movable connecting rod 28 on the movable pull ring 24 will drive the movable extrusion plate 29, the light rod 210, the limit bolt button 212 and the side guide block 211 to move toward the vertical keel member 12, and the movable extrusion plate 29 will contact the vertical keel member 12, and the side guide block 211 on the movable extrusion plate 29 will contact the two sides of the vertical keel member 12. The side guide block 211 structure is set to an arc design, and the fixed extrusion plate 27 and the movable extrusion plate 29 are L-shaped. When the keel 11 and the vertical keel member 12 are squeezed, the arc structure contacts the vertical keel member 12, which guides the position of the vertical keel member 12 so that the vertical keel member 12 can slide to the position between the two side guide blocks 211, and then the L-shaped keel 11 and the vertical keel member 12 are squeezed by the fixed squeezing plate 27 and the movable squeezing plate 29, so as to ensure that the L-shaped keel 11 and the vertical keel member 12 are in close contact. At the same time, in the process of the movable pull ring 24 moving toward the grip plate 23, the upper limit plate 215 connected to the bottom of the movable pull ring 24 will also move accordingly. The movement of the upper limit plate 215 will squeeze the lower limit plate 214 downward, and the spring between the lower limit plate 214 and the bottom frame 213 will accumulate force and contract. When the fixed squeezing plate 27 and the movable squeezing plate 29 complete the squeezing of the L The operator can release the grip of the grip plate 23 and the movable pull ring 24 to squeeze the L-shaped keel 11 and the vertical keel 12. The spring will release the stored force to make the lower limit plate 214 and the upper limit plate 215 fit tightly. Release the pulling of the movable pull ring 24. Under the influence of the toothed structure between the lower limit plate 214 and the upper limit plate 215, the movable pull ring 24 and the upper limit plate 215 will be limited. The tension spring between the movable pull ring 24 and the back plate 25 will not release the stored force. This structure is used to ensure that the clamping of the L-shaped keel 11 and the vertical keel 12 by the fixed extrusion plate 27 and the movable extrusion plate 29 can be locked. There is no need for the operator to pull the movable pull ring 24 for a long time, which reduces the burden on the operator. The L-shaped keel 11 and the vertical keel 12 are squeezed.It can make the two metal structures at the spot welding position contact more closely, and in the subsequent spot welding, they can be better melted together to form a firm welding point, thereby improving the mechanical strength and durability of the welding point. After the spot welding is completed, the pull ring 217 can be released by pulling downward to release the contact between the lower limit plate 214 and the upper limit plate 215, and the tension spring between the dynamic pull ring 24 and the back plate 25 will release the stored force, and the fixed extrusion plate 27 and the dynamic extrusion plate 29 will loosen the clamping of the L-shaped keel 11 and the vertical keel member 12. When the L-shaped keel 11 and the vertical keel member 12 are clamped, the movable pull ring 2 36 in the uniform spot welding component group 03 is pulled to move the movable pull ring 2 36 toward the grip plate 2 34. The tension spring between the movable pull ring 2 36 and the back plate 2 35 will accumulate force and stretch. The movement of the movable pull ring 2 36 will drive the movable upper rod frame 310 and the movable copper electrode head 311 to move toward the vertical keel member 12 and the L-shaped keel 11. At this time, the nut member 312 inside the movable upper rod frame 310 will drive the rifle rod 313 to rotate through the thread, and the rifle rod 313 will be, Fig.12 The outer disc 315 is rotated clockwise in the middle, and the clockwise rotation of the rifle rod 313 will not drive the outer disc 315. After the moving copper electrode head 311 contacts the vertical keel 12, the fixed copper electrode head 39 is connected to the moving copper electrode head 311 through the L-shaped keel 11 and the vertical keel 12. The L-shaped keel 11 and the vertical keel 12 between the fixed copper electrode head 39 and the moving copper electrode head 311 will conduct electricity and heat up, and then melt to complete the spot welding. Then release the pull on the moving pull ring 2 36, and the tension spring between the moving pull ring 2 36 and the back plate 2 35 will release the stored force, pulling the moving pull ring 2 36 back to its original position. At this time, the nut 312 will drive the rifle rod 313 through the thread. Fig.12 The outer disc 315 and the gear member 317 are rotated counterclockwise by the ratchet 316. Since the gear member 317 and the rack plate 318 are meshed, the gear member 317 moves on the rack plate 318, causing the upper moving frame 33, the movable pull ring 2 36, and the lower moving frame 37 to rotate counterclockwise. Fig.11The movable pull ring 36 is pulled and released each time, the fixed copper electrode head 39 and the movable copper electrode head 311 will be driven to move to the right at an equal distance. Through this design, the movable pull ring 36 is pulled each time to spot weld the fixed copper electrode head 39 and the movable copper electrode head 311, and the spacing between multiple spot welding positions is maintained consistent. After completing the uniform spot welding, the upper movable frame 33, the movable pull ring 36, and the lower movable frame 37 need to return to their original positions to prepare for spot welding at the next connection position. At this time, by pressing the disengagement button 320, one end of the push rod 319 will push the rack plate 318, and the rack plate 318 will slide in the slide groove of the upper outer frame plate 31, and the spring between the rack plate 318 and the upper outer frame plate 31 will accumulate force and shrink, so that the rack plate 318 will disengage and The gear part 317 is engaged, and the upper movable frame 33, the lower movable frame 37 and the back plate 35 can be moved back to their original positions, so that the fixed copper electrode head 39 and the movable copper electrode head 311 can be returned to the starting position to prepare for the spot welding of the next keel connection position. After adjusting the fixed copper electrode head 39 and the movable copper electrode head 311 to the starting position, release the pressure on the disengagement button 320, and the spring between the rack plate 318 and the upper outer frame plate 31 releases the stored force, which will push the rack plate 318 back to its original position, and the rack plate 318 will re-engage with the gear part 317. Compared with the method of manually controlling the spot welding spacing in the prior art, this device can achieve uniform spacing of the spot welding positions. The uniform spot welding spacing can improve the connection strength of the vertical keel member 12 and the L-shaped keel 11, thereby achieving the purpose of improving the bearing capacity. This light steel keel connection spot welding forming machine realizes adaptive adjustment and precise spot welding of keel members of different widths through a series of innovative designs, thereby improving welding quality and efficiency.
