Description

Technical Field

[0001] The present invention relates to the technical field of processing equipment, and specifically relates to a stainless steel coil welding machine. Background Art

[0002] In modern industrial production, stainless steel materials are widely used in many fields due to their excellent corrosion resistance, high strength, and good processing performance, such as architectural decoration, food processing, chemical equipment, and automobile manufacturing. Among them, stainless steel coils, as a common form of stainless steel materials, often need to be welded into the required structures or product components during subsequent processing. During the use of a stainless steel coil welding machine, generally, workers first place the coil at the bottom of the welding equipment, and then fix the two ends of the coil through two relatively moving clamping blocks to prevent displacement. However, when stabilizing a relatively thick coil with two relatively moving clamping blocks, the two contact surfaces of the coil combination will warp at both ends under the action of their own elasticity, resulting in a dislocation of the welding interface during subsequent welding, thus affecting the welding quality of the coil. Summary of the Invention

[0003] The purpose of the present invention is to provide a stainless steel coil welding machine to solve the problems raised in the above background art.

[0004] To solve the above technical problems, the present invention is realized through the following technical solutions: The present invention is a stainless steel coil welding machine, including a main body. A placement plate is fixedly connected to the top of the main body. A motor is fixedly connected to the top of the placement plate. The output shaft of the motor is rotationally connected to a threaded rod. A rectangular groove is opened on the side wall of the placement plate. It also includes; A clamping mechanism, which includes two fixed blocks, a first spring for shrinking under the thrust of an elastic plate, and a shrinking mechanism for moving back and forth through the shrinking of the first spring; The shrinking mechanism includes an L-shaped plate, a telescopic rod for rotating on the L-shaped plate, and an arc-shaped plate one for changing the arc through the rotation of the telescopic rod; The bottoms of the two fixed blocks are fixedly connected to the bottom inner wall of the rectangular groove. A rotating plate is rotationally connected to one side of the fixed block close to the fixed plate. An elastic plate is fixedly connected to the side of the rotating plate away from the fixed block.

[0005] Furthermore, a welding machine is slidably connected to the outer surface of the threaded rod. A fixed plate is fixedly connected to the side wall of the main body. A trapezoidal groove is opened on the top of the fixed plate.

[0006] Furthermore, a first spring is fixedly connected to the inner side wall of the elastic plate close to the rotating plate. A connecting rod is fixedly connected to the end of the elastic plate away from the rotating plate.

[0007] Further, one side of the L-shaped plate close to the elastic plate is fixedly connected to the elastic plate, and a telescopic rod is rotatably connected to one end of the L-shaped plate away from the elastic plate.

[0008] Further, an arc-shaped plate one is rotatably connected between the two telescopic rods, and the top of the L-shaped plate is rotatably connected to one end of the connecting rod away from the elastic plate; Among them, the arc-shaped plate one is made of an elastic material, and a number of rubber shafts are arranged on the outer surface of the arc-shaped plate one.

[0009] Further, a swinging mechanism is arranged inside the rectangular groove. The swinging mechanism includes two spring twos fixedly connected to the inner wall of the bottom of the rectangular groove, and two spring twos fixedly connected to the bottom of the rectangular groove at the bottom. The top of the spring two is fixedly connected to a swinging rod.

[0010] Further, a convex-shaped rod is fixedly connected to one side of the swinging rod close to the fixed block, and one end of the swinging rod away from the convex-shaped rod is rotatably connected to the inner wall of the bottom of the rectangular groove.

[0011] Further, an auxiliary mechanism is arranged on the front side of the rotating plate. The auxiliary mechanism includes an arc-shaped plate two fixedly connected to one side of the rotating plate close to the elastic plate. The arc-shaped plate two is elastic. Two inclined plates are fixedly connected to one end of the arc-shaped plate two away from the rotating plate. The sides of the two inclined plates close to the fixed block are provided with small openings.

[0012] Further, two support rods are arranged on the top of, and one side of the support rod close to the rotating plate is fixedly connected to the side wall of the rotating plate.

[0013] Further, a support block is fixedly connected to one side of the rotating plate away from the support rod, and the outer surface of the support block contacts the top of the swinging rod.

[0014] The present invention has the following beneficial effects: 1. In the present invention, by pushing the coiled plate, a thrust can be applied to the L-shaped plate to make it move when receiving the thrust. Through the movement of the L-shaped plate, the connecting rod can drive one end of the elastic plate to move downward. At this time, the downward-moving end of the elastic plate will squeeze the coiled plate, thereby realizing the fixation of the coiled plate. At the same time, by contacting one side of the coiled plate inside the elastic plate, the two ends of the coiled plate are aligned when pushing, preventing the situation that the two ends of the coiled plate are not aligned after being fixed when placing the coiled plate, reducing the influence on welding during the placement process of the coiled plate, and improving the quality of the fixation of the coiled plate.

[0015] 2. In the present invention, while the L-shaped plate moves, it will also drive the first arc-shaped plate to move inside the two inclined plates. At this time, the opened first arc-shaped plate will contract due to the change in the distance between the two inclined plates. At the same time, since the heights of the head and tail of the inclined plates are different, when the connecting rod drives the first arc-shaped plate to move, the connecting rod will be squeezed by the different heights of the inclined plates and then lift the arc-shaped plate, so that the arc-shaped plate can push the coiled plate, preventing the situation where the two ends of the coiled plate are stacked when it is fixed, thus affecting the subsequent processing of the coiled plate and improving the efficiency of fixing the coiled plate.

[0016] 3. In the present invention, after the coiled plate is fixed, due to the relatively thick coiled plate, the two ends of the coiled plate will warp due to the weight of the coiled plate itself. Then, the warped part of the coiled plate will contact the support rod, causing the support rod to push the rotating plate to rotate, further driving the support block to squeeze the swing rod. After being squeezed, the swing rod will drive the convex rod to move downward, thereby squeezing the warped coiled plate downward to make it contact the second arc-shaped plate, forming a butt joint at both ends of the coiled plate, effectively preventing the situation where the two ends of the coiled plate warp due to its own weight during the processing, thus improving the welding quality.

[0017] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-9 As shown, the present invention is a stainless steel coil welding machine, including a main body 1. A placing plate 101 is fixedly connected to the top of the main body 1. A motor 102 is fixedly connected to the top of the placing plate 101. The output shaft of the motor 102 is rotatably connected to a threaded rod 103. A rectangular groove is opened on the side wall of the placing plate 101. Further included is; A clamping mechanism 2, which includes two fixed blocks 201, a first spring 204 for shrinking under the thrust of the elastic plate 203, and a shrinking mechanism 3 for moving back and forth by shrinking through the first spring 204; The shrinking mechanism 3 includes an L-shaped plate 301, a telescopic rod 302 for rotating on the L-shaped plate 301, and a first arc-shaped plate 303 for changing the arc by rotating through the telescopic rod 302; The bottoms of the two fixed blocks 201 are fixedly connected to the bottom inner wall of the rectangular groove. A rotating plate 202 is rotatably connected to one side of the fixed block 201 close to the fixed plate 105. An elastic plate 203 is fixedly connected to the side of the rotating plate 202 away from the fixed block 201. After placing the coil on the L-shaped plate 301 and pushing the coil towards the main body 1, when the coil moves, a thrust will be applied to the protruding part at one end of the L-shaped plate 301, causing the L-shaped plate 301 to move towards the main body 1 following the coil.

[0023] A welding machine 104 is slidably connected to the outer surface of the threaded rod 103. A fixing plate 105 is fixedly connected to the side wall of the main body 1. A trapezoidal groove is formed at the top of the fixing plate 105. The motor 102 located on the placing plate 101 is started. The motor 102 rotates the threaded rod 103 through the output end. When the threaded rod 103 rotates, the welding machine 104 can be synchronously driven to slide on the threaded rod 103, so as to realize the welding of both ends of the fixed coiled plate.

[0024] A first spring 204 is fixedly connected to the inner side wall of the elastic plate 203 close to the rotating plate 202. One end of the elastic plate 203 far from the rotating plate 202 is fixedly connected to a connecting rod 205. When the connecting rod 205 moves, it will pull the elastic plate 203 connected to one end of the connecting rod 205 to bend downward, so that the downward-bent end of the elastic plate 203 contacts the top of the coiled plate, thereby applying pressure to the coiled plate to make the downward-bent end of the coiled plate contact the top of the coiled plate.

[0025] One side of the L-shaped plate 301 close to the elastic plate 203 is fixedly connected to the elastic plate 203. One end of the L-shaped plate 301 far from the elastic plate 203 is rotatably connected to a telescopic rod 302. After the coiled plate is placed on the L-shaped plate 301 and then the coiled plate is pushed towards the main body 1, when the coiled plate moves, it will apply a thrust to the protruding part at one end of the L-shaped plate 301, so that the L-shaped plate 301 moves towards the main body 1 following the coiled plate.

[0026] An arc-shaped plate 303 is rotatably connected between the two telescopic rods 302. The top of the L-shaped plate 301 is rotatably connected to one end of the connecting rod 205 far from the elastic plate 203; Among them, the arc-shaped plate 303 is made of an elastic material, and a number of rubber shafts are arranged on the outer surface of the arc-shaped plate 303. Then when the L-shaped plate 301 moves, it will drive the telescopic rod 302 at one end to move. When the telescopic rod 302 moves, the arc-shaped rod will be squeezed by the inclined plate and contract, so that the contact area between the rubber balls on the surface of the arc-shaped plate 303 and the inclined plate becomes larger, thereby increasing the friction between the rubber balls and the inclined plate and realizing the fixation after the coiled plate moves.

[0027] A swing mechanism 4 is arranged inside the rectangular groove. The swing mechanism 4 includes two second springs 401 fixedly connected to the inner wall of the bottom of the rectangular groove. The two second springs 401 fixedly connected to the bottom of the rectangular groove. The top of the second spring 401 is fixedly connected to a swing rod 402. When the swing rod 402 swings downward, it will squeeze one end of the second spring 401 and at the same time make the second spring 401 contract downward.

[0028] The side of the swing rod 402 close to the fixed block 201 is fixedly connected to the convex rod 403, and the end of the swing rod 402 away from the convex rod 403 is rotatably connected to the bottom inner wall of the rectangular groove. When the swing rod 402 swings downward, it will drive the convex rod 403 to move downward and squeeze the raised parts at both ends of the rolling plate downward, so that the two ends of the rolling plate are aligned.

[0029] An auxiliary mechanism 5 is provided on the front side of the rotating plate 202, and the auxiliary mechanism 5 includes an arc plate 2 501 fixedly connected to the side of the rotating plate 202 close to the elastic plate 203. The arc plate 2 501 is elastic, and one end of the arc plate 201 away from the rotating plate 202 is fixedly connected to two inclined plates. The two inclined plates are provided with a small opening on one side close to the fixed block 201, and the bottoms of the two rotating plates 202 will approach each other. In the process of the bottoms of the two rotating plates 202 approaching each other, the arc plate 2 501 will be squeezed, so that the arc plate 2 501 bulges upward, thereby supporting the rolling plate.

[0030] Two support rods 502 are set on the top of 501. The side of the support rod 502 close to the rotating plate 202 is fixedly connected to the side wall of the rotating plate 202. When the two ends of the rolling plate are tilted upward, they will contact the support rod 502, thereby applying a thrust to the support rod 502 so that the support rod 502 pushes the rotating plate 202 to rotate.

[0031] A support block 503 is fixedly connected to one side of the rotating plate 202 away from the support rod 502. The outer surface of the support block 503 contacts the top of the swing rod 402. When the rotating plate 202 rotates, the support block 503 is driven to rotate. When the support block 503 rotates, the swing rod 402 is swung downward.

[0032] During use, after placing the coiled plate on the L-shaped plate 301, the coiled plate is pushed towards the main body 1. When the coiled plate moves, a thrust is applied to the protruding part at one end of the L-shaped plate 301, causing the L-shaped plate 301 to move towards the main body 1 following the coiled plate. When the L-shaped plate 301 moves, a thrust is applied to the first spring 204 at one end, causing the first spring 204 to contract. When the L-shaped plate 301 moves, a pulling force is applied to one end of the connecting rod 205 close to the L-shaped plate 301, driving the connecting rod 205 to move. When the connecting rod 205 moves, the elastic plate 203 connected to one end of the connecting rod 205 is pulled to bend downward, so that the downward-bent end of the elastic plate 203 contacts the top of the coiled plate, thereby applying a pressure to the coiled plate to make the downward-bent end of the coiled plate contact the top of the coiled plate. Then, when the L-shaped plate 301 moves, one end of the telescopic rod 302 is driven to move. When the telescopic rod 302 moves, the arc-shaped rod is squeezed by the inclined plate and contracts, increasing the contact area between the rubber ball on the surface of the first arc-shaped plate 303 and the inclined plate, thereby increasing the friction between the rubber ball and the inclined plate, realizing the fixation after the coiled plate moves. At the same time, by contacting the inside of the elastic plate 203 with one side of the coiled plate, the two ends of the coiled plate are aligned when pushed, preventing the situation where the two ends of the coiled plate are not aligned after being fixed when placing the coiled plate, reducing the influence on welding during the placement process of the coiled plate, and improving the quality of fixing the coiled plate.

[0033] While the L-shaped plate 301 is moving, since one end of the telescopic rod 302 is driven to move, when the telescopic rod 302 moves, it contacts the inclined plate at the bottom and swings upward, achieving the effect of lifting the first arc-shaped plate 303 upward during the movement. When the telescopic rod 302 moves, it drives the first arc-shaped plate 303 to move within the two inclined plates. During the movement of the first arc-shaped plate 303, since the distance between the two inclined plates gradually decreases, the first arc-shaped plate 303 is squeezed by the inclined plates and contracts while moving upward, thereby pushing the coiled plate and preventing the situation where the two ends of the coiled plate are stacked when fixed, which may affect the subsequent processing of the coiled plate, and improving the efficiency of fixing the coiled plate.

[0034] After the coiled plate is fixed, there is no device at the bottom to support the coiled plate. Therefore, the coiled plate will fall downward due to inertia. Since the coiled plate is fixed, the two ends of the coiled plate located inside the two clamping mechanisms will be pulled upward by the bottom and warp. When the two ends of the coiled plate warp upward, they will contact the support rod 502 and exert a thrust on the support rod 502, causing the support rod 502 to push the rotating plate 202 to rotate. When the rotating plate 202 rotates, the bottoms of the two rotating plates 202 will approach each other. During the process of the bottoms of the two rotating plates 202 approaching each other, the second arc-shaped plate 501 will be squeezed, causing the second arc-shaped plate 501 to bulge upward, thereby supporting the coiled plate. While the rotating plate 202 rotates, it will drive the support block 503 to rotate. When the support block 503 rotates, the swing rod 402 will swing downward. When the swing rod 402 swings downward, it will squeeze one end of the second spring 401 and cause the second spring 401 to contract downward. While the swing rod 402 swings downward, it will drive the convex rod 403 to move downward and squeeze the bulging parts at both ends of the coiled plate, aligning the two ends of the coiled plate. Finally, start the motor 102 located on the placement plate 101. The motor 102 rotates the threaded rod 103 through the output end. When the threaded rod 103 rotates, it can synchronously drive the welding machine 104 to slide on the threaded rod 103, thereby welding the two ends of the fixed coiled plate. Through the downward extrusion of the convex rod 403, it effectively prevents the coiled plate from warping at both ends due to its own weight during the processing, thereby improving the welding quality.
