Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, and in particular to a pressure resistance welding machine for steel grating production. Background Technology

[0002] Resistance welding machines for steel grating production are commonly used in the steel grating manufacturing industry. They utilize the resistance heating effect to weld crossbars and flat steel under electrode pressure and current. They can precisely control welding parameters, achieve efficient connection, and ensure the structural stability and dimensional accuracy of the steel grating. They are widely used in industrial platform construction, building tread fabrication, and other fields to improve production efficiency and quality.

[0003] In practical applications, existing pressure resistance welding machines, through the use of transformers and electrodes, can basically meet the requirements for pressure welding of steel gratings, but the following problems still exist:

[0004] When performing double-sided precision welding on steel grating, common pressure resistance welding machines require manual and mechanical cooperation to remove the steel grating and reposition it for secondary welding after welding one side, which greatly reduces work efficiency. At the same time, during secondary welding, the placement of the steel grating inevitably shifts, affecting the welding effect. Therefore, this application provides a pressure resistance welding machine for steel grating production to meet the requirements. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a pressure resistance welding machine for steel grating production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pressure resistance welding machine for steel grating production, comprising a support frame and an electrode welding module disposed at the bottom of the support frame;

[0007] A flipping assembly is placed on the side of the electrode welding module. The flipping assembly includes a support rod fixed to the top of the electrode welding module. A sliding block is fixedly connected to the bottom of the support rod at the end away from the electrode welding module. A rotating block is fixedly connected to the side of the sliding block near the electrode welding module. A snap-fit ​​plate is provided on the top of the rotating block.

[0008] The positioning component is placed on the side of the flipping component near the electrode welding module and is used to assist the flipping component in flipping the steel grating. The positioning component includes a protective shell installed at the bottom of the electrode welding module. A toothed rack is provided on the top of the protective shell, and a movable plate is fixedly connected to the top of the toothed rack at the end away from the electrode welding module.

[0009] The sliding block has a fixed rod rotatably connected to one side of its bottom. A first spring is fixedly connected to the side of one end of the fixed rod. A connecting rod is fixedly connected to the end of the first spring away from the fixed rod. The end of the connecting rod away from the first spring is rotatably connected to the side of the sliding block near the fixed rod.

[0010] In a preferred embodiment, a limiting rod is fixedly connected to the side of the sliding block near the fixed rod, and a limiting plate is provided at one end of the sliding block.

[0011] The technical effect of adopting the above technical solution is that by setting a limiting rod, the connecting rod can be supported, and by setting a limiting plate, the movement trajectory of the sliding block can be limited.

[0012] In a preferred embodiment, a snap-fit ​​block is fixedly connected to the side of the rotating block, and a sliding frame is provided at the bottom of the snap-fit ​​block.

[0013] The technical effect of adopting the above technical solution is that by setting the snap-fit ​​block, the steel grating, the movable plate and the template can be rotated; by setting the sliding frame, the rotating block can be rotated.

[0014] In a preferred embodiment, one end of the movable plate is provided with a template, the inner cavity of the template is provided with a groove, and a slider is slidably connected to the inner cavity of the groove.

[0015] The technical effect of adopting the above technical solution is that by setting the groove, the movement trajectory of the slider can be limited.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] By setting up an electrode welding module, the steel grating can be precisely processed. A drive motor is set at the bottom of the rack. In use, the steel grating is first arranged, and then the motor is started. The output shaft of the motor rotates forward, which causes the rack to move. This allows the steel grating to be aligned by moving the moving plate. At this time, the electrode welding module is started, which allows the electrode welding module to weld the steel grating. After welding, the electrode welding module moves upward, which drives the sliding block to move upward through the support rod. When the sliding block moves to a certain position, the top of the locking block engages with the inner cavity of the locking plate. At the same time, the lever set on the side of the rotating block contacts the bottom of the sliding frame, which causes the locking block to drive the locking plate to rotate clockwise. This allows the steel grating to be directly rotated, avoiding the need to remove and rotate it after welding one side, effectively improving work efficiency. During the rotation process, the movement trajectory of the rotating block is limited by the cooperation of the connecting rod, the first spring piece, and the fixing rod.

[0026] 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.

[0027] like Figure 1 - Figure 3 As shown, this embodiment provides a technical solution: a pressure resistance welding machine for steel grating production, including: a support frame 1 and an electrode welding module 11 disposed at the bottom of the support frame 1;

[0028] The flipping component 2 is placed on the side of the electrode welding module 11. The flipping component 2 includes a support rod 21 fixed to the top of the electrode welding module 11. A sliding block 22 is fixedly connected to the bottom of the support rod 21 away from the electrode welding module 11. A rotating block 28 is fixedly connected to the side of the sliding block 22 close to the electrode welding module 11. A snap-fit ​​plate 210 is provided on the top of the rotating block 28.

[0029] Positioning component 3 is placed on the side of flipping component 2 near electrode welding module 11 and is used to assist flipping component 2 in flipping steel grating. Positioning component 3 includes a protective shell 31 installed at the bottom of electrode welding module 11. A rack 32 is provided on the top of the protective shell 31. A movable plate 33 is fixedly connected to the top of the rack 32 at the end away from electrode welding module 11.

[0030] Among them, a fixed rod 26 is rotatably connected to one side of the bottom of the sliding block 22, a first spring piece 25 is fixedly connected to the side of one end of the fixed rod 26, a connecting rod 24 is fixedly connected to the end of the first spring piece 25 away from the fixed rod 26, the end of the connecting rod 24 away from the first spring piece 25 is rotatably connected to the side of the sliding block 22 near the fixed rod 26, a limit rod 27 is also fixedly connected to the side of the sliding block 22 near the fixed rod 26, a limit plate 23 is provided at one end of the sliding block 22, a snap-fit ​​block 29 is fixedly connected to the side of the rotating block 28, a sliding frame 211 is provided at the bottom of the snap-fit ​​block 29, and the bottom of the inner wall of the sliding frame 211 is... A fixing block 212 is fixedly connected to the steel grating. By setting up the electrode welding module 11, the steel grating can be precision-processed. A drive motor is installed at the bottom of the rack 32. In use, the steel grating is first arranged, then the motor is started. The motor's output shaft rotates forward, causing the rack 32 to move. This movement allows the moving plate 33 to push the steel grating, aligning it. Then, the electrode welding module 11 is activated to weld the steel grating. After welding, the electrode welding module 11 moves upward. The movement allows the sliding block 22 to move upward via the support rod 21. When the sliding block 22 reaches a certain position, the top of the locking block 29 engages with the inner cavity of the locking plate 210. Simultaneously, the lever located on the side of the rotating block 28 contacts the bottom of the sliding frame 211, causing the locking block 29 to rotate the locking plate 210 clockwise. This directly rotates the steel grating, avoiding the need to remove the steel grating after welding one side, thus improving work efficiency. When the rotating block 28 rotates clockwise, it drives the connecting rod 24 to rotate. The clockwise rotation causes the first spring piece 25 to stretch. When the connecting rod 24 rotates to a certain position, the first spring piece 25 releases stress, causing one end of the connecting rod 24 to contact the top of the limiting rod 27. This limits the movement trajectory of the rotating block 28, preventing the rotating block 28 from shifting and causing damage. After the rotation is completed, the rotating block 28 continues to rise, causing the snap-fit ​​block 29 to disengage from the inner cavity of the snap-fit ​​plate 210. At this time, the electrode welding module 11 presses down again, allowing for precision processing of the other side of the steel grating.

[0031] Going a step further, such as Figure 3 and Figure 4As shown: A template 34 is provided at one end of the movable plate 33. A groove 36 is provided in the inner cavity of the template 34. A slider 35 is slidably connected to the inner cavity of the groove 36. A movable block 37 is slidably connected to the top of the inner wall of the template 34. A second spring piece 38 is fixedly connected to the side of the movable block 37. A snap-fit ​​module is provided on the side of the movable plate 33 opposite to the template 34. The connection between the rack 32 and the movable plate 33 is made by a snap-fit. After the two ends of the steel grating are aligned, the movable plate 33 snaps into the side of the template 34. At this time, the snap-fit ​​between the rack 32 and the movable plate 33 is manually removed, so that the movable plate 33 and the template 34 can form a whole. At the same time, it can avoid the rack 32 from affecting the flipping operation. The slider 35 and the side of the movable block 37 are both provided with With matching ramp angles, after the steel grating is placed, when the rack 32 drives the moving plate 33 to move towards the center of the electrode welding module 11, it can drive the slider 35 to move along the inner cavity of the groove 36. When the slider 35 moves to a certain position, the side of the slider 35 contacts the side of the moving block 37, thereby causing the moving block 37 to move towards the outside of the template 34. This enables the moving block 37 to position and clamp the two sides of the steel grating, ensuring that the top of one end of the steel grating always faces upward during the pressure welding and flipping process, avoiding positional deviation when placing the hemp steel. By setting the second spring 38, the stress generated by the contact between the moving block 37 and the steel grating can be absorbed.

[0032] Because the steel grating is clamped by the moving block 37 via the moving plate 33 and slider 35, it is not clamped synchronously as a whole, but rather in segments, with the alignment of both ends completed simultaneously. This causes the side of the steel grating to rub against the side of the moving block 37 for a period of time. Figure 4 As shown: In this solution, a flexible clamping plate 39 is fixedly connected to the side of the second spring 38. By setting the shape of the flexible clamping plate 39 to be arc-shaped, the frictional stress generated between the steel grating and the flexible clamping plate 39 can be effectively reduced, thus avoiding damage to the steel grating. At the same time, the outer surface of the flexible clamping plate 39 is provided with slight protrusions, which effectively improves the clamping effect and prevents the position of the steel grating from shifting during the flipping process.

[0033] Working principle:

[0034] like Figure 1-4 As shown:

[0035] In use: First, place the steel grating into the inner cavity of the template 34 and arrange it. Then, start the motor located at the bottom of the rack 32. The motor's output shaft rotates forward, causing the rack 32 to move towards the center of the electrode welding module 11. This, in turn, causes the slider 35 to move along the inner cavity of the groove 36 via the moving plate 33. When the slider 35 reaches a certain position, its side contacts the side of the moving block 37, causing the moving block 37 to move outward from the template 34. This achieves the effect of positioning and clamping the two sides of the steel grating, simultaneously positioning both ends of the steel grating. After clamping, remove the buckle located at the connection between the rack 32 and the moving plate 33. At this point, electrode welding is initiated. Module 11 enables the electrode welding module 11 to weld the steel grating. After welding, the electrode welding module 11 moves upward, which in turn drives the sliding block 22 to move upward via the support rod 21. When the sliding block 22 moves to a certain position, the top of the locking block 29 engages with the inner cavity of the locking plate 210. At the same time, the lever on the side of the rotating block 28 contacts the bottom of the sliding frame 211, which causes the locking block 29 to rotate the locking plate 210 clockwise, thereby achieving the effect of rotating the steel grating. After the rotation is completed, the rotating block 28 continues to rise, which causes the locking block 29 to disengage from the inner cavity of the locking plate 210. At this time, the electrode welding module 11 presses down again, finally completing the two-sided welding of the steel grating.
