Technical Field

[0001] The present application relates to the technical field of steel grating processing, and in particular to a pressure welding device for steel grating production. Background Art

[0002] Steel grating is also called mesh grille. It is a kind of steel product that is made of flat steel arranged crosswise with a certain spacing and cross bars, and welded into a square grid in the middle. It is usually welded by welding equipment.

[0003] Related technologies can refer to the Chinese patent with publication number CN117984019A, which discloses an automated welding device for steel gratings, including: a support structure and a steel bar conveying structure, the support structure includes a processing table and a plurality of vertical rods fixedly connected to the upper end of the processing table, the upper ends of the plurality of vertical rods are fixedly connected with the same horizontal top plate, and the same welding assembly is connected between the plurality of vertical rods, the upper side of the processing table is driven with a plurality of parallel steel plates, and the output end of the steel plate is driven by an external traction device, the upper end of the processing table is provided with a rectangular groove, and a limit assembly for limiting the steel plate is provided in the rectangular groove.

[0004] During welding, several long strips of flat steel are usually placed in parallel, and then cross bars are placed on top of the flat steels for welding and fixing. However, due to the long length of the flat steels, the flat steels are prone to vibrate during the operation of the equipment and the movement of the flat steels, causing themselves to tilt or twist. In this case, the quality of the steel grating is poor when the cross bars are welded to the flat steels. Summary of the invention

[0005] In order to improve the welding quality of steel gratings, the present application provides a pressure welding device for the production of steel gratings.

[0006] The present application provides a pressure welding device for steel grating production using the following technical solution:

[0007] A pressure welding device for producing steel gratings includes a processing table, a welding table is vertically slidably connected above the processing table, a welding head is provided below the welding table, and pressure plates are provided below the welding table on both sides of the welding head, clamping grooves corresponding to flat steels are opened on the pressure plates, and clamping plates for clamping flat steels are slidably connected in the clamping grooves.

[0008] By adopting the above technical solution, the steel grating is placed on the processing table, the welding table is lowered, the pressing plate is pressed on the upper surface of the flat steel to clamp and fix it, the clamping pieces are inserted on both sides of the flat steel and move toward the flat steel to clamp the flat steel, and the pressing plate and the clamping piece clamp and fix the steel grating from both vertical and horizontal directions, thereby improving the stability of the flat steel during welding. The welding head welds the steel grating, and the pressing plate is pressed on both sides of the welding head, which ensures the stability of the steel grating during welding, thereby improving the welding effect and ensuring the quality of the steel grating.

[0009] Preferably, a mounting platform is provided on the processing platform, and the mounting platform is fixedly connected to the processing platform via a plurality of vertically arranged support rods. Guide cylinders corresponding to the support rods are fixed on the welding platform, and the guide cylinders are sleeved on the support rods.

[0010] By adopting the above technical solution, the guide cylinder and the support rod cooperate with each other to limit and guide the movement of the welding table, thereby improving the stability of the movement of the welding table.

[0011] Preferably, a vertically arranged slide groove is opened under the welding table, the pressure plate is slidably connected in the slide groove, and a plurality of buffer springs are arranged between the bottom of the slide groove and the pressure plate. When the buffer springs are in a natural state, the lower surface of the pressure plate is lower than the lower surface of the welding head.

[0012] By adopting the above technical solution, when the welding table is not performing welding operations, the buffer spring is in a natural state and the lower surface of the pressure plate is low. When the welding table descends to prepare for welding operations, the lower surface of the pressure plate first contacts the flat steel, thereby pressing and fixing the flat steel. The welding table continues to descend, and the buffer spring is compressed until the welding head moves to the welding position to start welding. The welding head then welds and fixes the flat steel, thereby ensuring the quality of welding.

[0013] Preferably, a plurality of vertically arranged guide rods are fixed in the slide groove, and a guide groove corresponding to the guide rod is formed on the pressure plate, and the lower end of the guide rod is slidably connected in the guide groove.

[0014] By adopting the above technical solution, the guide rod and the guide groove cooperate with each other to limit and guide the movement of the pressure plate to prevent it from running off the track and getting stuck.

[0015] Preferably, a bidirectional lead screw is rotatably connected in the clamping groove, and the upper ends of the clamping plates are respectively threadedly connected to the two ends of the bidirectional lead screw, and when the bidirectional lead screw rotates, the two clamping plates move toward or away from each other.

[0016] By adopting the above technical solution, the pressure plate is pressed down to the upper end of the flat steel, the bidirectional lead screw rotates, and the two clamping plates move toward the flat steel synchronously to clamp it, thereby improving the stability of the flat steel.

[0017] Preferably, the guide rod and the clamping groove correspond one to one, one end of the bidirectional lead screw passes through the clamping groove and is located in the guide groove, a driving gear is coaxially fixed to the end of the bidirectional lead screw, and the lower end of the guide rod is provided with a driving rack meshing with the driving gear.

[0018] By adopting the above technical solution, during the descent of the welding platform, the pressing plate and the welding platform are synchronously descended, and the pressing plate and the welding platform are relatively stationary. When the pressing plate is pressed on the upper end of the flat steel, the welding platform continues to descend, and the pressing plate slides in the slide groove. The guide rod and the driving rack are synchronously descended with the welding platform, and the driving rack drives the driving gear to rotate, thereby controlling the rotation of the bidirectional lead screw, so that the clamping plate moves toward the flat steel to clamp it. That is, during the descent of the welding platform, the pressing plate is pressed on the upper end of the flat steel, and the clamping plate automatically clamps the flat steel, without the need for an additional power source, saving space and reducing energy consumption.

[0019] Preferably, a clamping spring perpendicular to the clamping piece is provided on one side of the clamping pieces facing each other, and a buffer piece is fixed to one end of the clamping spring facing away from the clamping piece.

[0020] By adopting the above technical solution, the clamping plate moves toward the flat steel, the buffer plate clamps the flat steel, and the clamping spring provides buffering protection for the flat steel to prevent the buffer plate from exerting excessive pressure on the flat steel, thereby causing the flat steel to deform and affecting the quality of the steel grating.

[0021] Preferably, a guide rod perpendicular to the buffer plate is fixed to one end of the buffer plate facing the clamping plate, a guide hole matching the guide rod is opened on the clamping plate, and the guide rod is inserted into the guide hole and slidably connected to the guide hole.

[0022] By adopting the above technical solution, the guide rod and the guide hole cooperate with each other to limit and guide the movement of the buffer plate, thereby preventing the buffer plate from running off the track and affecting the clamping effect.

[0024] 1. Through the setting of the pressing plate and the clamping piece, the pressing plate presses and fixes the upper surface of the flat steel, and the clamping piece presses and fixes the two sides of the flat steel, and fixes the flat steel from both vertical and horizontal directions to improve the stability of the flat steel, thereby ensuring the welding effect of the welding head and improving the quality of the steel grating.

[0029] The present application is further described in detail below in conjunction with all the accompanying drawings. Example

[0030] The present application embodiment discloses a pressure welding device for producing steel gratings, referring to Figure 1 to Figure 2 , including a processing table 1 and a welding table 2, and a plurality of conveying rollers 12 are arranged in parallel on the processing table 1. A mounting table 5 is fixed above the processing table 1 through four vertically arranged support rods 11, and a hydraulic cylinder 51 is installed below the mounting table 5. The output shaft of the hydraulic cylinder 51 is connected to the welding table 2, and a guide cylinder 21 corresponding to the support rods 11 is fixed on the welding table 2, and the guide cylinder 21 is sleeved on the support rods 11. When the flat steel and the cross bar are placed on the processing table 1, the hydraulic cylinder 51 is started, and the welding table 2 is lowered to weld the flat steel and the cross bar to form a steel grating. After the welding is completed, the welding table 2 is lifted and reset.

[0031] Reference Figure 1 to Figure 2 A welding head 3 is fixed on the lower surface of the welding table 2, and the welding head 3 welds the flat steel and the cross bar. A pressing plate 4 is provided on both sides of the welding head 3 and is slidably connected to the welding table 2. The welding table 2 descends, and the pressing plate 4 presses on the flat steel and is located on both sides of the cross bar. The welding head 3 is directly opposite to the cross bar and welds the cross bar. The pressing plate 4 presses and fixes the flat steel, improves the stability of the flat steel, and prevents the flat steel from deviating or vibrating during welding and affecting the welding.

[0032] Reference Figure 1 to Figure 2 , the lower surface of the welding table 2 is provided with a slide groove 22 located on both sides of the welding head 3, and the pressure plate 4 is slidably connected in the slide groove 22. A plurality of buffer springs 23 are arranged in the slide groove 22, and the lower end of the buffer spring 23 is fixedly connected to the pressure plate 4. When the buffer spring 23 is in a natural state, the lower surface of the pressure plate 4 is lower than the lower surface of the welding head 3. When the welding table 2 moves downward, the pressure plate 4 contacts the flat steel first to be pressed and fixed, and as the welding table 2 continues to descend, the buffer spring 23 is compressed. The buffer spring 23 provides buffering protection for the flat steel to prevent the pressure of the pressure plate 4 on the flat steel from being too great and causing damage to the flat steel. Moreover, after welding is completed, when the welding table 2 is lifted, the buffer spring 23 provides power for the reset of the pressure plate 4.

[0033] Reference Figure 1 to Figure 2A plurality of vertically arranged guide rods 24 are fixed in the slide groove 22, and a plurality of guide grooves 43 corresponding to the guide rods 24 are provided on the pressing plate 4, and the lower ends of the guide rods 24 are slidably connected in the guide grooves 43. The guide rods 24 limit the movement of the pressing plate 4 to prevent it from running off and getting stuck.

[0034] Reference Figure 1 to Figure 2 The lower surface of the pressing plate 4 is provided with a plurality of clamping grooves 41 corresponding to the flat steels, and the guide grooves 43 correspond to and are connected to the clamping grooves 41. A bidirectional lead screw 44 is horizontally rotatably connected in the clamping groove 41, and clamping pieces 42 are threadedly connected at both ends of the bidirectional lead screw 44. When the bidirectional lead screw 44 rotates, the clamping pieces 42 move toward or away from each other. The pressing plate 4 is pressed on the upper surface of the flat steel, and the two clamping pieces 42 are located on both sides of the flat steel. When the bidirectional lead screw 44 rotates, the clamping pieces 42 clamp on both sides of the flat steel to fix it. The pressing plate 4 and the clamping pieces 42 clamp and fix the steel grating in both vertical and horizontal directions, thereby improving the stability of the flat steel during welding.

[0035] Reference Figure 1 to Figure 2 , one end of the bidirectional lead screw 44 near the guide groove 43 passes through the clamping groove 41 and extends into the guide groove 43 and is coaxially fixed with a driving gear 45, and the lower end of the guide rod 24 is fixed with a driving rack 25 meshing with the driving gear 45. When the pressing plate 4 presses on the upper end of the flat steel, the welding table 2 continues to descend, and the pressing plate 4 slides in the slide groove 22. The guide rod 24 and the driving rack 25 descend synchronously with the welding table 2, and the driving rack 25 drives the driving gear 45 to rotate, thereby controlling the rotation of the bidirectional lead screw 44, so that the clamping piece 42 moves toward the flat steel to clamp it. That is, during the descent of the welding table 2, the pressing plate 4 presses on the upper end of the flat steel, and the clamping piece 42 automatically clamps the flat steel, without the need for an additional power source, saving space and reducing energy consumption.

[0036] Reference Figure 1 to Figure 2 After welding is completed, the welding platform 2 rises. Due to the buffer spring 23, when the welding platform 2 is just lifted, the pressing plate 4 is still statically pressed on the flat steel. During the rising process of the welding platform 2, the guide rod 24 rises accordingly, thereby driving the bidirectional lead screw 44 to rotate in the opposite direction, and the two clamping pieces 42 move in opposite directions to release the flat steel. Until the buffer spring 23 is in the natural state, the pressing plate 4 rises synchronously with the welding platform 2 and separates from the steel grating.

[0037] Reference Figure 1 to Figure 2The clamping pieces 42 are provided with a clamping spring 46 perpendicular to the clamping piece 42 on the opposite side to each other, a buffer piece 47 is fixed to the end of the clamping spring 46 away from the clamping piece 42, and a guide rod 48 perpendicular to the buffer piece 47 is fixed to the end of the buffer piece 47 facing the clamping piece 42. A guide hole 49 matching the guide rod 48 is provided on the clamping piece 42, and the guide rod 48 is inserted into the guide hole 49 and slidably connected to the guide hole 49. The clamping piece 42 moves toward the flat steel, the buffer piece 47 contacts the flat steel and clamps the flat steel, and the clamping spring 46 provides buffer protection for the flat steel to prevent the buffer piece 47 from exerting too much pressure on the flat steel and causing deformation of the flat steel.

[0038] The implementation principle of the pressure welding equipment for steel grating production in the embodiment of the present application is as follows: the flat steel and the cross bar are placed on the processing table 1, the welding table 2 is lowered, the pressure plate 4 is pressed on the upper end of the flat steel, the buffer sheet 47 is pressed on both sides of the flat steel, and the welding head 3 welds the cross bar. After the welding is completed, the welding table 2 rises, the buffer sheet 47 releases the flat steel, the pressure plate 4 is detached from the top of the flat steel, and the welding table 2 is separated from the steel grating and reset.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
