Description

Technical Field

[0001] The invention relates to the technical field of steel bar welded mesh processing, and in particular to a processing device for an interlocking steel bar welded mesh. Background Art

[0002] Steel welded mesh is a mesh in which longitudinal and transverse steel bars are arranged at a certain interval and at right angles to each other, and all intersections are welded together by resistance spot welding. Generally, one mesh is produced at a time, and subsequent meshes are interlocked and packaged. During the production process of steel welded mesh, it is necessary to use corresponding cutting devices to cut the steel bars into appropriate sizes to facilitate the processor to weld the steel bars.

[0003] The existing cutting devices are all controlled individually and cannot be linked with the welding equipment, resulting in the cutting process being difficult to control. When using a welding machine for welding, the longitudinal steel bars are placed manually. Since the steel bars are circular in structure, they are prone to rolling when placed, causing the steel mesh to shift and affecting the quality of welding.

The number of steel bar rollers 13 is selected according to needs, and a welding mechanism is provided at the upper end of the front seat 2 of the machine tool.

[0025] like Figure 2As shown, the lower end of the processing machine tool 1 is fixedly installed with a rear block located at the rear side of the machine tool front seat 2, and the inner end surface of the machine tool front seat 2 is fixedly installed with a front block, and a certain distance is set between the front block and the rear block. A front self-rotating shaft 14 is rotatably installed on the front block, and a rear self-rotating shaft 15 is rotatably installed on the rear block. The front self-rotating shaft 14 and the rear self-rotating shaft 15 are arranged in the left and right directions. A plurality of rectangular holes 16 that penetrate up and down are evenly opened on the processing machine tool 1. The rectangular holes 16 are arranged in the front and back directions, and the number of the rectangular holes 16 is the same as the number of the steel bar rollers 13. The front end of the rectangular hole 16 is arranged inside the machine tool front seat 2, and each steel bar roller 13 is arranged corresponding to the rectangular hole 16 on the front side, and multiple first sprocket groups 17 are installed between the front rotating shaft 14 and the rear rotating shaft 15. Each first sprocket group 17 is arranged corresponding to the rectangular hole 16 above, and each first sprocket group 17 includes two first sprockets and a first chain. The front rotating shaft 14 and the rear rotating shaft 15 are respectively coaxially fixed with first sprockets, and a first chain is connected between every two corresponding front and rear first sprockets. A clamping mechanism is provided on each of the first sprocket groups 17, and a first steel bar 23 is wound around each steel bar roller 13, and the clamping mechanism is used for conveying the first steel bar 23.

[0026] like Figure 1 , Figure 2 , Fig. 9 As shown, a limiting frame 18 is fixedly installed on the top of the processing frame 3, and the limiting frame 18 is arranged at the rear side of the processing frame 3. A delivery box 19 is fixedly installed on the limiting frame 18, and the delivery box 19 is arranged in the left and right directions. A roller 20 is rotatably installed inside the delivery box 19, and the outer wall of the roller 20 is slightly in contact with the inner wall of the delivery box 19. A plurality of steel bar grooves 21 in the left and right directions are evenly arranged on the roller 20. The number of the steel bar grooves 21 is set according to needs, and the inner diameter of the steel bar groove 21 is slightly larger than the outer diameter of the second steel bar 24. A bevel box 22 is fixedly installed on the bottom end of the delivery box 19, and the bevel box 22 and the delivery box 19 are mutually connected, and the inner wall of the bevel box 22 is inclined forward, and a discharge hole is provided at the bottom end of the bevel box 22. The delivery box 19 is used to place a batch of second steel bars 24, and the inner diameter of the discharge hole is larger than the outer diameter of the second steel bar 24. The personnel place a batch of second steel bars 24 into the delivery box 19, and the second steel bars 24 will fall into the steel bar groove 21 above. Then, one end of the first steel bar 23 is installed on the corresponding clamping mechanism, and the multiple first sprocket groups 17 are driven to rotate together and move the first steel bars 23 forward. Each steel bar roller 13 rotates synchronously to transport the first steel bars 23. When the multiple first steel bars 23 move to the bottom of the inclined box 22, the roller 20 is driven to rotate and rotate the second steel bars 24 in the steel bar groove 21 to the bottom. Due to the self-gravity of the second steel bars 24, the second steel bars 24 will fall onto the inclined surface of the inclined box 22, and at the same time At this time, the second steel bar 24 at the top will gradually enter the empty steel bar groove 21. At this time, the second steel bar 24 will fall onto the first steel bar 23 below through the discharge hole along the inclined surface of the inclined surface box 22. The first steel bar 23 will overlap multiple second steel bars 24 in the left and right directions. The welding mechanism is turned on to weld each contact point between the first steel bar 23 and the second steel bar 24 at the same time. When the welding is completed, the first sprocket group 17 continues to rotate and transports the first steel bar 23 forward, driving the roller 20 to continue to rotate, and the second steel bar 24 in the steel bar groove 21 continues to overlap the first steel bar 23 below, and the welding mechanism continues to weld it. Due to the continuous rotation of the first sprocket group 17, the welded mesh on the front side is moved to the conveying roller 9, and the front end of the welded mesh is flush with the front end of the auxiliary frame 4. Then the two positioning gears 11 are rotated and the corresponding two driving racks 12 are moved. The pressure spring is continuously compressed, and the two push plates 6 bring the shearing knife 7 to approach each other and contact the first steel bar 23. When the two push plates 6 continue to approach each other, each buffer spring 8 will be gradually compressed until the two shearing knives 7 completely cut off the first steel bar 23. Then the positioning gear 11 is released. Due to the rebound force of the pressure spring, the two push plates 6 will quickly move away from each other and wait for the next cutting of the steel mesh. By continuously conveying the first steel bar 23 through the first sprocket group 17, the steel mesh can be continuously welded, which not only saves welding time, but also improves welding efficiency, reduces human operation, and improves automation. Due to the continuous rotation of the roller 20, not only intermittent feeding is achieved, but also the feeding speed and interval time can be controlled, thereby improving the welding quality and aesthetics of the steel mesh welding, ensuring that the spacing between each second steel bar 24 is roughly the same, improving work efficiency, saving time and labor costs, and not requiring human operation, thereby improving safety. The setting of the buffer spring 8 reduces the impact force between the shear knife 7 and the push plate 6 and extends the service life.

[0027] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 8As shown, the welding mechanism includes a welding gun rod 25, and a plurality of fixed blocks 26 are evenly fixedly installed at the front end of the limiting frame 18. The number of the fixed blocks 26 is the same as the number of the steel bar rollers 13. Each of the fixed blocks 26 is provided with a sliding hole that passes through the upper and lower parts, and a welding gun rod 25 that slides up and down is installed in each sliding hole. The bottom end of the welding gun rod 25 is provided with an existing suitable welding gun, and the welding gun is connected to the corresponding control device and power supply. Positioning holes are respectively provided between the left and right ends of the limiting frame 18, and synchronization rods 27 are installed in the two positioning holes to slide up and down. The two A cross bar is fixedly installed between the synchronization rods 27, and a compression spring is fixedly installed on the cross bar. The other end of the compression spring is fixedly installed on the top of the limiting frame 18. The compression spring can quickly reset the cross bar and the welding gun rod 25. A linkage rod 28 is fixedly installed on the top of each welding gun rod 25. Each linkage rod 28 is fixedly installed on the cross bar. Vertical guide slots 29 are respectively provided at the left and right ends of the limiting frame 18. A guide rod 30 is fixedly installed on each synchronization rod 27. The guide rod 30 is slidably installed in the corresponding guide slot 29 up and down. When welding the steel mesh, turn on the power supply and control equipment, and drive the two guide rods 30 to slide downward with the synchronization rod 27 at the same time. The cross bar pushes each welding gun rod 25 to slide downward through the linkage rod 28, and the compression spring is compressed. At this time, the welding gun welds each contact point between the first steel bar 23 and the second steel bar 24 at the same time. When the welding is completed, release the two guide rods 30, and the compression spring drives the welding gun rod 25 to reset through the corresponding components. The first sprocket group 17 continues to rotate and transports the first steel bar 23 forward, driving the roller 20 to continue to rotate, and the second steel bar 24 in the steel bar groove 21 continues to overlap the first steel bar 23 below, and the welding mechanism continues to weld it. The up and down reciprocating motion of the welding gun improves the welding quality and makes the welding point more perfect.

[0028] like Figure 3 , Fig.11 As shown, each of the clamping mechanisms includes an extension rod 31, and a plurality of extension rods 31 are evenly fixedly installed on the outer end surface of each of the first chains. The number of the extension rods 31 is selected according to needs. A positioning shell 32 is fixedly installed on the top of each of the extension rods 31, and arc-shaped spring pieces 33 are fixedly installed at both ends of each positioning shell 32. The tops of every two arc-shaped spring pieces 33 are arranged close to each other. The arc-shaped spring pieces 33 are made of existing suitable metal materials and are elastic. A clamping plate 34 is fixedly installed on the top of each of the arc-shaped spring pieces 33. The clamping plate 34 is slidably connected to the inner wall of the positioning shell 32, and friction blocks 35 are fixedly installed on the close ends of every two clamping plates 34. When the first steel bar 23 is transported, the personnel install each first steel bar 23 between the corresponding two clamping plates 34. Since the arc-shaped spring piece 33 is elastic, the friction block 35 and the outside of the first steel bar 23 are squeezed and contacted with each other, and then the first sprocket group 17 is rotated, and the positioning shell 32 carries the corresponding first steel bar 23 to be transported forward. When each positioning shell 32 on the front side moves to the first sprocket, the positioning shell 32 will move around the outer side of the first sprocket to the lower side, and the first steel bar 23 will be separated from between the two friction blocks 35. Since the first steel bar 23 is always stuck between multiple clamping plates 34, and at the same time, the positioning shell 32 on the rear side moves around the outer side of the first sprocket to the upper side, driving every two clamping plates 34 to be clamped on the first steel bar 23, the friction block 35 and the first steel bar 23 are in a close contact state, so that the first steel bar 23 can be continuously transported forward. Since the arc-shaped spring piece 33 is elastic, the first steel bar 23 will not be separated from the clamping plate 34 and the friction block 35, thereby improving the transportation stability of the first steel bar 23.

[0029] like Figure 3 , Fig.10 As shown, a transverse plate 36 is fixedly installed at the rear end of the processing machine tool 1, and the transverse plate 36 is arranged on the front side of the steel bar roller 13. A plurality of clamping rings 37 are evenly and fixedly installed at the lower end of each of the transverse plates 36. The number of the clamping rings 37 is selected according to needs. The clamping rings 37 are always clamped on the first steel bar 23 to exert a downward pressure on the first steel bar 23; when the positioning shell 32 moves around the outer side of the first sprocket to the upper side, since the clamping rings 37 are always clamped on the first steel bar 23, every two clamps 34 can be quickly clamped on the first steel bar 23 at this time.

[0030] like Figure 1 , Figure 8 As shown, the left and right ends of the limiting frame 18 are respectively rotatably installed with a toggle plate 38, and the two toggle plates 38 are coaxially fixedly connected to the roller 20. A plurality of toggle rods 39 are evenly fixedly installed on the circumferential end of each of the toggle plates 38, and the number of toggle rods 39 is selected according to needs. A second sprocket group 40 is installed between each of the toggle plates 38 and the corresponding front rotating shaft 14. The second sprocket group 40 includes two second sprockets and a second chain. The front rotating shaft 14 and the outer ends of the toggle plate 38 are respectively coaxially fixedly installed with second sprockets, and a second chain is connected between the two second sprockets. A motor 41 is fixedly installed on the left end of the limiting frame 18, and the rotating shaft of the motor 41 is coaxially fixedly installed with the second sprocket on the lower side. The motor 41 is connected to the controller, and the controller is connected to the power supply.

[0031] like Figure 1 , Figure 8As shown, each of the positioning gears 11 is coaxially fixedly installed with a gear shaft 42 extending backward, the bevel gear set 43 includes a front bevel gear and a rear bevel gear, the rear end of each gear shaft 42 is coaxially fixedly installed with a front bevel gear, the left and right ends of the front seat 2 of the machine tool are respectively rotatably installed with front drive gears 44, each of the front drive gears 44 is coaxially fixedly installed with a rear bevel gear, the front bevel gear is meshed with the rear bevel gear, the left and right ends of the front seat 2 of the machine tool are respectively rotatably installed with rear drive gears 45, each rear drive gear 45 is meshed with the corresponding front drive gear 44, and the two second sprockets located below are respectively coaxially fixedly installed with sector gears 46; The personnel install each first steel bar 23 between the corresponding two clamping plates 34, and the front end of the first steel bar 23 is located at the lower rear side of the bevel box 22. The power is turned on, and the controller starts the motor 41 to rotate the second sprocket set 40 and the fan gear 46 synchronously. The front self-rotating shaft 14 rotates with multiple first sprocket sets 17 and the rear self-rotating shaft 15. Each first sprocket set 17 moves forward with the corresponding first steel bar 23. During the rotation of each steel bar roller 13, the first steel bar 23 is conveyed forward. When multiple first steel bars 23 move to the right below the bevel box 22, the two toggle plates 38 rotate with the rollers 20 at this time, and the second steel bars 24 in the steel bar groove 21 fall through the discharge hole onto the first steel bars 23 below. Then the first sprocket set 17 continues to move forward with the corresponding first steel bar 23. At this time, the two toggle rods 39 will press the corresponding guide rod 30 and slide the synchronization rod 27 downward. The cross bar pushes each welding gun rod 25 to slide downward through the linkage rod 28. The compression spring is compressed, and the welding gun quickly welds each contact point between the first steel bar 23 and the second steel bar 24. When the welding is completed, the toggle plate 38 slides with the toggle rod 39 against the guide rod 30 until it quickly disengages from the guide rod 30. The compression spring drives the welding gun rod 25 to rebound upward and reset quickly through the corresponding components. The first sprocket set 17 continues to rotate and slides with the first steel bar 23 and pushes the welding mesh forward. At the same time, the second steel bar 24 at the rear side continues to fall onto the first steel bar 23 below, and the welding gun quickly welds each contact point between the first steel bar 23 and the second steel bar 24. When the welding mesh moves to the conveying roller 9, the fan gear 46 meshes with the rear drive gear 45 to rotate, the rear drive gear 45 meshes with the front drive gear 44 to rotate, the front drive gear 44 meshes with the rear bevel gear to rotate, the two gear shafts 42 rotate with the corresponding positioning gears 11, the upper drive rack 12 moves downward, the lower drive rack 12 moves upward, the pressure spring continues to compress until the two push plates 6 push the shear knife 7 to quickly cut the first steel bar 23 completely, the staff can remove the cut steel mesh, when the fan gear 46 disengages from the rear drive gear 45, the rebound force of the pressure spring drives the two push plates 6 to quickly move away from each other, waiting for the next cutting of the steel mesh; In this way, the steel mesh can be welded and cut continuously, which reduces the number of human operations, improves automation, saves time and labor costs. Due to the setting of the fan gear 46 and the toggle plate 38, intermittent cutting and welding are achieved, which will not cause the steel mesh to deviate, improves the welding quality, helps to reduce production costs, and can replace manual labor to complete repetitive and high-intensity work, reducing the demand for operating workers and improving safety and welding efficiency.

The front end of the inclined block 54 is provided with a downwardly inclined inclined surface, and each inclined block 54 is provided corresponding to the moving rack 50 on the front side; When each welding gun rod 25 moves downward, the sliding bar 48 located on the rear side will stick to the corresponding inclined surface of the inclined block 54 and slide forward along the inclined surface, and the linkage gear 52 will engage with the corresponding two moving racks 50 to slide. At this time, the two sliding bars 48 are close to each other and push the corresponding second steel bars 24 to move through the two push plates 49. The reset spring 53 is compressed, which can drive the second steel bars 24 to a vertical state in the left and right directions. At this time, the welding gun quickly welds each contact point between the first steel bar 23 and the second steel bar 24, and there will be no welding point offset. When the welding is completed, the welding gun rod 25 moves upward, and the rebound force of the reset spring 53 drives the two sliding bars 48 and the push plates 49 to return to their initial state. Compared with the manual placement of the longitudinal steel bars, this method can avoid the disorder of the longitudinal steel bars during welding, thereby improving the welding quality and appearance.
