A welding apparatus for steel member production

Abstract

This utility model relates to a welding equipment for steel component production, comprising a welding table and a T-shaped steel component mounted on the welding equipment. The welding table is equipped with a limiting structure to restrict deformation during the welding process of the T-shaped steel component. The limiting structure includes a support frame with two clamping support components mounted on the support frame. This welding equipment for steel component production controls the sliding of a guide frame, which moves the left-side clamping support component closer to the workpiece, ensuring that the L-shaped abutment plate is in contact with the non-welded side of the flange plate. A clamping plate moves vertically downward along the guide rod, pressing the web plate against the vertical surface of the L-shaped abutment plate, forming a three-dimensional positioning system of lateral constraint on the flange plate and longitudinal fixation of the web plate. Furthermore, the L-shaped abutment plate transmits rigid support force through an H-shaped bracket, preventing the flange plate from warping towards the non-welded side. A support plate compresses the flange plate and stretches the spring, forming a controllable preload. Utilizing the stress buffer principle, compensation space is reserved for subsequent thermal deformation.

Description

Technical Field

[0001] This utility model relates to the field of steel component production and processing technology, specifically a welding equipment for steel component production. Background Technology

[0002] Steel component manufacturing and processing refers to the production of steel structural components that meet engineering design requirements through a series of processes, including design refinement, raw material processing, cutting and blanking, forming and processing, hole making, assembly and welding, surface anti-corrosion, and quality inspection. These components are widely used in industrial plants, high-rise buildings, bridges, stadiums, and mechanical equipment. The core requirements are high precision, strength, and durability. Among these, assembly and welding refers to connecting multiple parts through welding to form a complete steel component. This is the core link between parts processing and finished components, and it directly determines the structural strength, geometric accuracy, and stability of the steel component, serving as the core guarantee for the strength of the steel component.

[0003] In the current technology, welding of T-shaped steel components requires the use of welding equipment. The components are fixed by positioning clamps on the welding equipment, ensuring that the web plate is perpendicular to the flange plate. Then, the welding operation is carried out. Finally, the unpenetrated weld roots on the back are removed until the fusion line of the weld on the front is exposed, thus completing the welding of the T-shaped steel component. In the production and processing of thinner T-shaped steel components, the web plate is welded to one side of the flange plate. The heat is concentrated only on the welded side, resulting in a significant temperature gradient difference between the welded and non-welded sides. This leads to uneven heating between the welded and non-welded areas, causing thermal expansion and contraction. During the heating expansion stage, the welded side expands, generating stress towards the non-welded side. During the cooling contraction stage, the welded metal begins to cool and contract. The flange plate generates torque through expansion and contraction, causing the flange plate to warp or bend towards the non-welded side. Therefore, a welding equipment for steel component production is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a welding device for steel component production. It offers the advantage of rigidly constraining the flange plate, solving the problem that in the production of thin T-shaped steel components, when the web plate is welded to one side of the flange plate, heat is concentrated only on the welded side, creating a significant temperature gradient difference between the welded and non-welded sides. This results in uneven heating between the welded and non-welded areas, leading to thermal expansion and contraction. During the heating expansion phase, the welded side expands, generating stress towards the non-welded side. During the cooling contraction phase, the welded metal begins to cool and contract, and the flange plate, through expansion and contraction, generates torque, causing the flange plate to warp or bend towards the non-welded side.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a welding equipment for the production of steel components, comprising a welding table and a T-shaped steel component disposed on the welding equipment, wherein the welding table is provided with a limiting structure for limiting the deformation generated during the welding process of the T-shaped steel component; The limiting structure includes a support frame that is slidably mounted on a welding table. The support frame is provided with two clamping support components for limiting the web and flange of the T-shaped steel member. The two clamping support components are symmetrically distributed on the left and right. A linear actuator with a telescopic end fixedly connected to the support frame is fixedly mounted on the welding table. The clamping support component on one side is also provided with an elastic support component for adaptively adjusting the pressure against the flange of the T-shaped steel member. The support frame includes a guide frame sleeved on the welding table, and the guide frame is slidably connected to the welding table. Two H-shaped brackets symmetrically distributed on the top of the guide frame are fixedly installed. The clamping support component includes an L-shaped abutment plate for abutting the non-welded side of the flange plate of the T-shaped steel component, and the L-shaped abutment plate is fixedly connected to one end of the H-shaped bracket. A clamping plate for clamping the web plate of the T-shaped steel component is slidably installed at the bottom of the L-shaped abutment plate. An electric push rod is fixedly installed on the L-shaped abutment plate, and the telescopic end of the electric push rod is fixedly connected to the clamping plate.

[0006] Furthermore, the elastic support component includes a support plate for abutting the welded side of the flange plate of the T-shaped steel component. Two guide columns penetrating the L-shaped abutment plate are fixedly installed on one side of the support plate, and the guide columns are slidably connected to the L-shaped abutment plate. Two elastic elements are provided on the two guide columns, and the elastic elements are connected to the L-shaped abutment plate.

[0007] Furthermore, the elastic element includes two washers and a spring. The spring is fixedly installed between the two washers on opposite sides, and both washers and the spring are sleeved on the guide post. The washer at the end of the guide post is fixedly connected to the guide post, and the washer near the L-shaped abutment plate is fixedly connected to the L-shaped abutment plate.

[0008] Furthermore, both H-shaped supports are fixedly equipped with reinforcing plates to enhance the load at the corners of the H-shaped supports.

[0009] Furthermore, two guide rods are fixedly installed on the top of the clamping plate, and one end of the guide rod passes through the L-shaped abutment plate, with the L-shaped abutment plate and the guide rod slidably connected.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. This welding equipment for steel component production controls the guide frame to slide along the welding table and drive the left-side clamping support component to move closer to the workpiece, ensuring that the L-shaped abutment plate and the non-welded side of the flange plate are in contact. The clamping plate moves vertically downward along the guide rod to press the web plate against the vertical surface of the L-shaped abutment plate, forming a three-dimensional positioning system with lateral constraint of the flange plate and longitudinal fixation of the web plate. Moreover, the L-shaped abutment plate transmits rigid support force through the H-shaped bracket to prevent the flange plate from warping to the non-welded side. At this time, the connection node between the web plate and the flange plate is fixed, and the thermal expansion stress is concentrated in the weld area, avoiding macroscopic deformation caused by stress diffusion. 2. The welding equipment used for steel component production utilizes the support plate to contact the flange plate and then pushes the guide frame to stretch the spring, forming a controllable preload. Utilizing the stress buffering principle, it reserves compensation space for subsequent thermal deformation. The welding side expands due to heat, pushing the support plate, thereby using the elasticity of the spring to absorb the expansion stress. During the cooling and contraction stage, the spring rebounds to generate a reverse thrust, offsetting the contraction torque and preventing the flange plate from warping in the opposite direction. 3. The welding equipment used for steel component production utilizes a support plate to pre-contact the flange plate, ensuring that the clamping plate does not adhere to the side of the flange plate after welding, thus preventing the clamping plate from contacting the weld area when pressed down, and avoiding instability of the clamping web plate due to unevenness in the weld area.

[0013] 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.

[0014] Example 1: Please refer to Figure 1-4 This embodiment provides a welding device for producing steel components, including a welding table 1 and a T-shaped steel component 2 disposed on the welding device. The welding table 1 is provided with a limiting structure 3 for limiting the deformation of the T-shaped steel component 2 during the welding process.

[0015] Example 2: Please refer to Figure 1-4 Based on Embodiment 1, the limiting structure 3 includes a support frame 31 that is slidably mounted on the welding table 1. The support frame 31 is provided with two clamping support components 32 for limiting the web and flange of the T-shaped steel member 2. The two clamping support components 32 are symmetrically distributed on the left and right. A linear actuator 33 with its telescopic end fixedly connected to the support frame 31 is fixedly mounted on the welding table 1. An elastic support component 34 for adaptively adjusting the pressure against the flange of the T-shaped steel member 2 is also provided on one side of the clamping support component 32. The support frame 31 includes a guide frame 311 sleeved on the welding table 1, and the guide frame 311 is slidably connected to the welding table 1. Two H-shaped brackets 312 that are symmetrically distributed on the left and right are fixedly installed on the top of the guide frame 311. The clamping support component 32 includes an L-shaped abutment plate 321 for abutting against the non-welded side of the flange of the T-shaped steel component 2, and the L-shaped abutment plate 321 is fixedly connected to one end of the H-shaped bracket 312. A clamping plate 322 for clamping the web of the T-shaped steel component 2 is slidably installed on the bottom of the L-shaped abutment plate 321. An electric push rod 323 is fixedly installed on the L-shaped abutment plate 321, and the telescopic end of the electric push rod 323 is fixedly connected to the clamping plate 322.

[0016] Among them, two H-shaped brackets 312 are fixedly installed with reinforcing plates 313 to enhance the load at the corners of the H-shaped brackets 312. The addition of reinforcing plates 313 at the corners of the brackets forms a stable structure, thereby increasing the load of the H-shaped brackets 312.

[0017] In addition, two guide rods are fixedly installed on the top of the pressing plate 322, and one end of the guide rod passes through the L-shaped abutment plate 321. The L-shaped abutment plate 321 is slidably connected to the guide rod. Two guide rods that pass through the L-shaped abutment plate 321 are set on the top of the pressing plate 322. The guide rods and the electric push rod 323 form a dual-axis drive, which improves the uniformity of pressure distribution.

[0018] Using the above technical solution, the linear actuator 33 is activated, and its telescopic end drives the guide frame 311 to slide along the welding table 1. The left clamping support component 32 is pushed to the side of the workpiece through the H-shaped bracket 312, ensuring that the L-shaped abutment plate 321 is in contact with the non-welded side of the flange plate. The electric push rod 323 is activated, driving the clamping plate 322 to move vertically downward along the guide rod, pressing the web plate against the vertical surface of the L-shaped abutment plate 321, forming a three-dimensional positioning system with lateral constraint of the flange plate and longitudinal fixation of the web plate. The first side joint between the flange plate and the web plate is welded. The L-shaped abutment plate 321 transmits rigid support force through the H-shaped bracket 312, preventing the flange plate from warping to the non-welded side. At this time, the connection node between the web plate and the flange plate is fixed, and the thermal expansion stress is concentrated in the weld area, avoiding macroscopic deformation caused by stress diffusion.

[0019] Example 3: Please refer to Figure 1-4 Based on Embodiment 2, the elastic support component 34 includes a support plate 341 for abutting against the welded side of the flange plate of the T-shaped steel component 2. Two guide posts 342 that penetrate the L-shaped abutment plate 321 are fixedly installed on one side of the support plate 341, and the guide posts 342 are slidably connected to the L-shaped abutment plate 321. Two elastic elements 343 are provided on the two guide posts 342, and the elastic elements 343 are connected to the L-shaped abutment plate 321.

[0020] The elastic element 343 includes two washers and a spring. The spring is fixedly installed between the two washers on opposite sides, and both washers and the spring are sleeved on the guide post 342. The washer at the end of the guide post 342 is fixedly connected to the guide post 342, and the washer near the L-shaped abutment plate 321 is fixedly connected to the L-shaped abutment plate 321. The combination of double washers and springs is adopted. The washers are fixed to the guide post 342 and the L-shaped abutment plate 321 respectively, which restricts the lateral displacement of the spring and uses the spring force to achieve pre-tightening force control and counteract the contraction torque.

[0021] Using the above technical solution, after the support plate 341 contacts the flange plate, it continues to push the guide frame 311 to stretch the spring in the elastic element 343, forming a controllable preload. Utilizing the stress buffering principle, it reserves compensation space for subsequent thermal deformation. The right electric push rod 323 is activated, and the clamping plate 322 fixes the web plate again. When welding the second side joint, the welding side expands due to heat, pushing the support plate 341. Thus, the elasticity of the spring absorbs the expansion stress. During the cooling and contraction stage, the spring rebounds and generates a reverse thrust to offset the contraction torque and prevent the flange plate from warping in the opposite direction.

[0022] The working principle of the above embodiments is as follows: The welding equipment used for steel component production initially connects the web and flange of the T-shaped steel component 2 by spot welding, and then places the T-shaped steel component 2 on the welding table 1. The linear actuator 33 is activated to retract and move the guide frame 311. The moving guide frame 311 moves the clamping support component 32 toward the T-shaped steel component 2 through the H-shaped bracket 312 until the L-shaped abutment plate 321 contacts the flange plate side of the T-shaped steel component 2. Start the electric push rod 323 to drive the clamping plate 322 to move slowly down until it contacts the surface of the web plate, thereby pressing the T-shaped steel component 2 onto the welding table 1. At this time, the L-shaped abutment plate 321 abuts against the flange plate and the clamping plate 322 abuts against the web plate. Then, the other side of the flange plate and the web plate are welded. Through the rigid support of the L-shaped abutment plate 321, the flange plate is restricted from warping and deforming to the non-welded side. After the welding on this side is completed, the clamping state of the T-shaped steel component 2 is released, the linear actuator 33 is activated to extend, and the guide frame 311 is driven to move in the opposite direction. During the movement of the guide frame 311, the T-shaped steel component 2 is temporarily fixed by auxiliary tooling. The moving guide frame 311 drives the pressing support component 32 and the elastic support component 34 on the other side to move synchronously until the support plate 341 in the elastic support component 34 abuts against the welded side of the flange plate of the T-shaped steel component 2 and stretches the spring in the elastic element 343 until the pressing plate 322 on this side moves to the top of the web plate, then the electric push rod 323 on this side is activated and the pressing plate 322 is controlled to press the web plate. At this time, the clamping plate 322 abuts against the web plate and the support plate 341 abuts against the flange plate on the side where welding is completed. Then, welding is performed on the unwelded side. The force of the support plate 341 and the elastic element 343 is used to counteract the stress generated during the flange plate welding process, thus limiting the flange plate from warping to the unwelded side.
