Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel welding, and more specifically to a device for conveniently welding stainless steel. Background Art

[0002] Stainless steel is the abbreviation of stainless acid-resistant steel. It is a type of steel that is resistant to weak corrosive media such as air, steam, and water or has stainless properties. Welding stainless steel is a common stainless steel processing technology. In the prior art, when welding and connecting multiple sections of tubular stainless steel, the connecting ends of the steel pipes are mostly aligned manually. During the welding process, the steel pipes lack effective fixation and support, and are easily misaligned.

[0003] Chinese patent authorization announcement number: CN218016841U provides a stainless steel duct welding shaping device, which uses a magnetic suction component to bring the sliding plate into contact with the duct body, drives the rack plate to move through the first drive component, and the rack plate drives the sliding plate to move synchronously. The sliding plate synchronously drives the duct body to move and contact inside the connecting sleeve under the guidance of the guide component, so that the moving and clamping processing of the stainless steel duct can be automatically adjusted, which is convenient for the use of the device; the orientation of the welding head can be adjusted by manually adjusting the fastening knob, and the moving orientation can be adjusted by driving the connecting ring through the moving component, and the gear ring can be driven to rotate by the second drive component. The gear ring drives the clamped welding head to perform rotation welding processing, thereby realizing the welding processing and shaping processing of the stainless steel duct, which is convenient for the use of the device.

[0004] However, in this solution, the inner diameter of the connecting sleeve for supporting the stainless steel pipe remains unchanged. When the diameter of the steel pipe to be processed is larger than the inner diameter of the connecting sleeve, the steel pipe cannot be inserted. When the diameter of the steel pipe is smaller than the inner diameter of the connecting sleeve, the electromagnet is affected by the adsorption of one end of the steel pipe, which easily causes one end of the steel pipe to tilt up, and the alignment of the steel pipes at both ends cannot be achieved, resulting in poor practicality of the solution and being unable to adapt to stainless steel pipes of various calibers. Therefore, a device for convenient welding of stainless steel is proposed to address the above problems. Utility Model Content

This scheme realizes the clamping and fixation of two sections of stainless steel pipes by arranging mutually symmetrical placement blocks and abutment blocks in a pair of annular limit blocks, which can ensure that the two sections of steel pipes are flush with each other after fixation to avoid warping of one end of the steel pipe. The V-shaped structure of the placement block and the abutment block can keep the steel pipe in the center position, so that the steel pipes at both ends are aligned with each other and avoid rolling of the steel pipe. The movable abutment block allows the device to be adapted to steel pipes of various different calibers, effectively improving the practicability of the device, improving the stability of stainless steel pipes during welding, and providing convenience for users' welding work.

[0037] Example:

[0038] See also Figure 1-2 A device for convenient welding of stainless steel comprises a base 1, a pair of mutually symmetrical supporting blocks 2 are fixedly connected to the base 1, an annular mounting block 3 is fixedly connected to the supporting block 2, a pair of annular mounting blocks 3 are rotatably connected to an annular limiting block 4 at one end close to each other, a placement block 5 is fixedly connected to the bottom end of the inner wall of the annular limiting block 4, and an electric push rod 6 is installed on the top end of the inner wall of the annular limiting block 4, an abutment block 7 is fixedly connected to the output end of the electric push rod 6, a pair of placement blocks 5 are in the same horizontal position, the placement block 5 and the abutment block 7 are both arranged in a V-shaped structure, and the concave surfaces of the placement block 5 and the abutment block 7 are symmetrical to each other.

[0039] Welding stainless steel is a common stainless steel processing technology. In the prior art, when welding and connecting multiple sections of tubular stainless steel, the connecting ends of the steel pipes are mostly aligned manually. During the welding process, the steel pipes lack effective fixation and support, and are easily misaligned. In this solution, the user can respectively pass the stainless steel pipes that need to be welded at both ends through the inner cavities of a pair of annular mounting blocks 3 and a pair of annular limiting blocks 4, so that the stainless steel pipes abut against the upper ends of the placement blocks 5, and the connecting ends of the stainless steel pipes at both ends abut against each other, and then simultaneously start a pair of electric push rods 6 to push downward, so that a pair of abutment blocks 7 respectively abut against the top ends of a pair of stainless steel pipes, thereby clamping the stainless steel pipes and fixing the stainless steel pipes between the abutment blocks 7 and the placement blocks 5. Since the pair of placement blocks 5 are in the same horizontal position, it can be ensured that the two sections of the steel pipes are flush with each other after being fixed, and the V-shaped structure of the placement block 5 and the abutment block 7 can keep the steel pipe in the center position and avoid rolling of the steel pipe. The movable abutment block 7 allows the device to be adapted to a variety of steel pipes with different calibers.

[0040] See also Figure 2 A rubber pad 8 is installed at one end of the placement block 5 and the abutment block 7 close to each other.

[0041] By setting the rubber pads 8, multiple rubber pads 8 can be made close to the surface of the steel pipe when the abutment block 7 and the placement block 5 clamp the steel pipe, which can enhance the friction between the abutment block 7, the placement block 5 and the steel pipe and improve the stability of the steel pipe during welding. At the same time, the setting of the rubber pads 8 can prevent the abutment block 7 and the placement block 5 from scratching the steel pipe during the clamping process.

[0042] See also Figure 1 and 3 A servo motor 10 is installed at one end of one of the support blocks 2, and a connecting rod 11 is fixedly connected to the output end of the servo motor 10. The connecting rod 11 is rotatably connected to the other support block 2 at one end away from the servo motor 10. The outer ends of a pair of annular limit blocks 4 are fixedly connected to gear rings 9, and the outer ends of the connecting rod 11 are fixedly connected to a pair of gears 12, and the pair of gears 12 are respectively meshed with a pair of gear rings 9.

[0043] A pair of gear rings 9 are meshedly connected with a pair of gears 12, so that when the gears 12 do not rotate, the pair of annular limit blocks 4 are restricted by the gear rings 9 and cannot rotate on the annular mounting block 3, thereby keeping the pair of placement blocks 5 always symmetrical with each other, which is convenient for the user to place the steel pipe. During the welding process, the user can start the servo motor 10 to drive the connecting rod 11 to rotate, and then drive the pair of gears 12 to rotate synchronously. The gear 12 drives the gear ring 9 to rotate, and then drives the pair of annular limit blocks 4 to rotate synchronously on the annular mounting block 3, so that the steel pipes at both ends rotate synchronously when they are in contact with each other. This arrangement can facilitate the user to perform circumferential welding on the connecting ends of the steel pipe while standing in place, avoiding the user from moving back and forth.

[0044] Working principle:

[0045] When in use, the user passes the stainless steel pipes that need to be welded at both ends through the inner cavities of a pair of annular mounting blocks 3 and a pair of annular limiting blocks 4 respectively, so that the stainless steel pipes abut against the upper end of the placement block 5, and the connecting ends of the stainless steel pipes at both ends abut against each other, then simultaneously start a pair of electric push rods 6 to push downward, so that a pair of abutting blocks 7 abut against the top ends of a pair of stainless steel pipes respectively, thereby clamping the stainless steel pipes and fixing the stainless steel pipes between the abutting blocks 7 and the placement blocks 5, then the user starts the servo motor 10 to drive the connecting rod 11 to rotate, and then drives a pair of gears 12 to rotate synchronously, and drives the gear ring 9 to rotate through the gear 12, and then drives a pair of annular limiting blocks 4 to rotate synchronously on the annular mounting block 3, so that the steel pipes at both ends rotate synchronously when they abut against each other. At this time, the user can stand in place and perform circumferential welding on the connecting ends of the steel pipes without moving back and forth.

[0046] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
