Description

Technical Field

[0001] The invention relates to the technical field of welding machines, in particular to a welding machine for producing high-reliability and high-load drill rod springs. Background Art

[0002] In the field of exploration and exploitation of resources such as oil and natural gas, drill pipe springs play a vital role. During the drilling process, drill pipes need to cope with extremely complex and harsh working environments, including huge axial pressure, frequent vibration shock, high temperature and high pressure, and corrosive media. With the continuous increase in drilling depth and the continuous improvement of drilling efficiency and safety requirements, higher standards are put forward for the performance of drill pipe springs. Traditional drill pipe spring production processes and related welding equipment have gradually exposed many limitations.

[0003] The patent with publication number CN215824627U relates to a welding machine for producing pneumatic valve springs, including a base body, a clamping mechanism, a connecting assembly and a top assembly. The clamping mechanism is fixedly connected to the top of the base body, and the top assembly is fixedly installed on the top of the base body through two connecting assemblies; the connecting assembly includes a fixing plate, and a hydraulic cylinder is fixedly installed at the bottom of the fixing plate. The device realizes a welding machine for producing pneumatic valve springs through the mutual cooperation of the base body, the clamping mechanism, the connecting assembly and the top assembly, which greatly improves the protection effect of the welding machine and effectively prevents welding sparks from flying around. The welding machine can purify welding fumes and protect workers. It is highly safe to use and makes it easy to remove the top assembly from the base body, which facilitates the maintenance and repair of components in the welding machine. It also makes it easy to replace the purification filter element, which reduces the workload of workers. However, in the process of fixing and clamping the spring, the clamping plate of the device is a straight plate, which can easily cause the spring to fall off during welding, making it difficult to effectively fix and support the spring. Therefore, a high-reliability and high-load-bearing drill rod spring production welding machine is proposed to solve the above-mentioned problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a high-reliability and high-load-bearing welding machine for producing drill rod springs in view of the deficiencies in the above-mentioned prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a high-reliability and high-load drill pipe spring production welding machine, including a welding table, the top of the welding table is fixedly connected with a baffle, the top of the welding table is provided with a clamping device, the inner wall of the clamping device is provided with a discharging device, the bottom of the welding table is provided with a collecting device, and the welder is installed at the bottom of the baffle; the clamping device includes a side plate, a support plate, a motor, a bidirectional threaded rod, a sliding plate 1, a sliding rod, an arc plate, a fixed rod, a V-shaped telescopic plate, a fixed plate, a fixed frame, an L-shaped plate, and an inner clamping plate, the side plate is fixedly connected to the top of the welding table, the support plate is fixedly connected to the right side of the side plate, the motor is fixedly connected to the top of the welding table, the bidirectional threaded rod is fixedly connected to the output end of the motor, the sliding plate 1 is threadedly connected to the circumferential surface of the bidirectional threaded rod, the sliding rod is slidably connected to the inner wall of the side plate, the arc plate is fixedly connected to the right side of the sliding rod, the fixed rod is fixedly connected to the bottom of the support plate, and the V-shaped telescopic plate is rotatably connected to the circumference of the fixed rod through a torsion spring The top of the support plate contacts with the bottom of the arc plate, the surface of the fixed plate contacts with the inner wall of the arc plate, the top of the fixed plate contacts with the bottom of the inner plate, and the inner wall of the sliding plate is fixedly connected to the circumferential surface of the sliding rod. When the spring is welded, the drill rod spring is placed on the top of the fixed plate, and the movement of the sliding rod drives the arc plate to move, so that the surface of the drill rod spring can be clamped, so that the drill rod spring can reduce the pressure of the fixed plate supporting during the welding process, thereby improving the stability of the drill rod spring during the welding process, and the inner arc surface of the arc plate can be wrapped to further improve the stability of the device. The rotation of the V-shaped telescopic plate drives the inner plate to move, so that the inner wall of the drill rod spring can be clamped and fixed, thereby increasing the firmness of the drill rod spring during the welding process.

[0006] Preferably, the discharging device includes a connecting plate 1, a sliding plate 2, an inclined plate 1, an inclined plate 2, and a telescopic rod, wherein the connecting plate 1 is fixedly connected to the rear of the L-shaped plate, the sliding plate 2 is fixedly connected to the top of the connecting plate 1, the inclined plate 1 is fixedly connected to the rear of the connecting plate 1, the inclined plate 2 is slidably connected to the inner wall of the fixed frame, and the telescopic rod is rotatably connected to the inner wall of the inclined plate 2, and the discharging device also includes an auxiliary plate, a lifting block, and an I-shaped plate, wherein the auxiliary plate is fixedly connected to the left side of the telescopic rod, the lifting block is slidably connected to the inner wall of the inclined plate 2, and the I-shaped plate is fixedly connected to the top of the lifting block The inner wall of the sliding plate 2 is threadedly connected to the circumferential surface of the bidirectional threaded rod, and the top of the inclined plate 1 is in contact with the bottom of the inclined plate 2. When welding is completed, the movement of the inclined plate 2 drives the I-shaped plate to move, so that the drill rod spring placed on the top of the I-shaped plate can be pushed out, which can facilitate workers to take out the welded drill rod spring, thereby improving the welding efficiency of the drill rod spring. At the same time, when the drill rod spring is placed in the welding area, the rotation of the telescopic rod drives the auxiliary plate to rotate, so that the circumferential surface of the drill rod spring can be auxiliary limited, avoiding instability during the process of pushing the drill rod spring out.

[0007] Preferably, the collecting device includes a rotating rod, a shaking plate, a protrusion, and a collecting box. The rotating rod is fixedly connected to the inner wall of the welding table. The shaking plate is rotatably connected to the circumferential surface of the rotating rod through a torsion spring. The protrusion is fixedly connected to the bottom of the shaking plate.

The inner wall of the collection box is in contact with the bottom of the cleaning plate. When the drill rod spring is pushed out, the protrusion will fall and drive the shaking plate to fall, so that the shaking plate can be shaken back and forth through multiple protrusions, and then the welding slag dropped on the surface of the shaking plate can be shaken off, thereby improving the cleaning effect of the welding slag after welding. At the same time, the movement of the connecting plate 2 drives the cleaning plate to move, so that the residual welding slag dropped in the collection box can be scraped off, avoiding the welding slag from adhering to and accumulating on the inner wall of the collection box for a long time, resulting in the inability to clean the welding slag on the inner wall of the collection box after a long time.

[0008] The present invention adopts the above technical solution to bring the following beneficial effects: 1. The high-reliability and high-load-bearing drill stem spring production welding machine operates through the cooperation between the welding table, baffle, side plate, support plate, motor, bidirectional threaded rod, sliding plate, sliding rod, arc plate, fixed rod, V-shaped telescopic plate, fixed plate, fixed frame, L-shaped plate and inner clamping plate. When the spring starts to be welded, the drill stem spring is placed on the top of the fixed plate, and the movement of the sliding rod drives the arc plate to move, so that the surface of the drill stem spring can be clamped, so that the drill stem spring can reduce the pressure of the fixed plate supporting during the welding process, thereby improving the stability of the drill stem spring during the welding process, and can also wrap the surface of the spring through the inner arc of the arc plate to further improve the stability of the device. At the same time, the rotation of the V-shaped telescopic plate drives the inner clamping plate to move, so that the inner wall of the drill stem spring can be clamped and fixed, thereby increasing the firmness of the drill stem spring during the welding process.

[0009] 2. The high-reliability and high-load-bearing welding machine for producing drill stem springs works in coordination with the connecting plate 1, the sliding plate 2, the inclined plate 1, the inclined plate 2, the telescopic rod, the auxiliary plate, the lifting block and the I-shaped plate. When welding is completed, the inclined plate 2 moves to drive the I-shaped plate to move, thereby ejecting the drill stem spring placed on the top of the I-shaped plate, making it convenient for workers to take out the welded drill stem spring, thereby improving the welding efficiency of the drill stem spring. At the same time, when the drill stem spring is placed in the welding area, the rotation of the telescopic rod drives the auxiliary plate to rotate, thereby assisting in limiting the circumferential surface of the drill stem spring, thereby avoiding instability during the process of pushing out the drill stem spring.

[0010] 3. The high-reliability and high-load-bearing welding machine for producing drill stem springs cooperates with the rotating rod, shaking plate, protrusion, collection box, connecting plate 2, top plate and cleaning plate to operate. When the drill stem spring is pushed out, the protrusion will fall and drive the shaking plate to fall, so that the shaking plate can be reciprocated by multiple protrusions, and then the welding slag dropped on the surface of the shaking plate can be shaken off, thereby improving the cleaning effect of the welding slag after welding. At the same time, the movement of connecting plate 2 drives the movement of the cleaning plate, so that the welding slag dropped in the collection box can be scraped off, avoiding the welding slag from adhering to and accumulating on the inner wall of the collection box for a long time, resulting in the inability to clean the welding slag on the inner wall of the collection box after a long time.
