Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding tooling technology, specifically to a tooling for welding angle steel components. Background Technology
[0002] Angle steel components are commonly used in the manufacture of engineering machinery and equipment, such as the standard fishplate section of tower cranes. Welding connectors (e.g., connecting plates) to the inner and outer surfaces of one end of the angle steel is a frequent practice in angle steel component production. In the mass production of such components, after assembling and positioning the angle steel body and connectors using tooling, tack welding is used to initially fix the angle steel body and connectors, and then the components are transferred to another tooling for full welding. During the welding process, the high temperatures can easily cause the angle steel components to bend and deform after welding. Furthermore, the connectors, which connect to the angle steel body via the weld, are prone to angular changes relative to the angle steel body during welding, leading to non-compliance with product design requirements and compromised welding quality. However, existing tooling for full welding of angle steel components only has a simple fixing function and cannot solve the above problems. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a tooling for welding angle steel components that can balance welding deformation, improve welding quality, and is easy to implement and apply.
[0004] The present invention adopts the following technical solution:
[0005] A tooling for welding angle steel components includes: a base; two supports disposed on the base with a certain distance between them; a clamping device for clamping the angle steel component onto the two supports; and a deformation positioning component disposed between the two supports and at a height lower than the supports. The clamping device is located between the two supports and can compress the portion of the angle steel component located between the two supports to bend downwards and abut against the deformation positioning component. Before welding, the deformation positioning component and the clamping device can cooperate to force the portion of the angle steel component located between the two supports to bend downwards by a predetermined arc, thereby balancing the overall bending deformation of the angle steel component caused by high temperature during welding and improving the welding quality.
[0006] Preferably, the deformation positioning component is installed on the base in a height-adjustable manner through a height adjustment assembly. The height adjustment assembly enables the deformation positioning component to have vertical displacement capability, and the bending curvature of the angle steel can be precisely controlled by adjusting the height of the deformation positioning component.
[0007] Preferably, the height adjustment assembly includes a lifting seat and a lifting drive mounted on the base. The lifting seat is located on the drive end of the lifting drive and can move up and down as the drive end of the lifting drive extends and shortens. The mechanical combination of the lifting drive and the lifting seat forms a stable and reliable linear lifting mechanism.
[0008] Preferably, the lifting drive component is one of a telescopic cylinder, a telescopic hydraulic cylinder, or an electric push rod, and a standardized power element (cylinder / hydraulic cylinder / electric push rod) is selected as the core of the lifting drive, which has both fast response and precise position control characteristics.
[0009] Preferably, the base is provided with an end positioning assembly, which includes an end positioning seat for positioning one end of the angle steel member against the end positioning seat and an end positioning drive mechanism for pushing the angle steel member to move and abut against the end positioning seat. The end positioning assembly achieves accurate lateral positioning of the angle steel member through active driving.
[0010] Preferably, the end positioning drive mechanism includes a pusher and a telescopic drive that drives the pusher to move closer to and away from the end positioning seat.
[0011] Preferably, the support includes a support seat disposed on the base and a roller rotatably fitted on the support seat. The roller-type support structure converts sliding friction into rolling friction, which greatly reduces the moving resistance of the angle steel.
[0012] Preferably, the clamping device includes a pressure block and a cylinder that drives the pressure block to move up and down.
[0013] Preferably, the base is also provided with an anti-deformation device, which includes a positioning plate and an anti-deformation drive mechanism that drives the positioning plate to move between a first position and a second position. This can prevent the connecting parts that are connected to the angle steel body through the weld from changing their angle relative to the angle steel body during the welding process, so that the product meets the design requirements and the welding quality is guaranteed.
[0014] Preferably, when the positioning plate is in the first position, the positioning plate simultaneously abuts against the connecting piece and the main body of the angle steel component; when the positioning plate is in the second position, the positioning plate disengages from the abutting engagement with the connecting piece and the main body of the angle steel component.
[0015] Compared with the prior art, the present invention has the following advantages: The present invention provides a tooling for welding angle steel components that can balance welding deformation, improve welding quality, and is easy to implement and apply. The clamping device is located between two support members and can compress the part of the angle steel component located between the two support members to bend downward and abut against the deformation positioning member. The tooling for welding angle steel components has a deformation positioning member with a height less than the height of the two support members between the two support members. Before welding, the deformation positioning member and the clamping device can cooperate to force the part of the angle steel component located between the two support members to bend downward by a predetermined arc, thereby balancing the overall bending deformation of the angle steel component caused by high temperature during the welding process and improving the welding quality.

[0021] In the figure, the components are: base 1, support 2, support seat 2-1, roller 2-2, clamping device 3, pressure block 3-1, cylinder 3-2, deformation positioning component 4, height adjustment assembly 5, lifting seat 5-1, lifting drive component 5-2, anti-deformation device 6, positioning plate 6-1, anti-deformation drive mechanism 6-2, end positioning assembly 7, end positioning seat 7-1, push component 7-2, telescopic drive component 7-3, connector 100, and angle steel body 200. Detailed Implementation
[0022] To facilitate understanding of the technical solution of this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.
[0023] Example 1
[0024] like Figure 1-5 As shown, a tooling for welding angle steel components includes:
[0025] Base 1;
[0026] Two support members 2 are set on the base 1, with a certain distance between them;
[0027] The clamping device 3 is used to clamp the angle steel component onto the two support members 2;
[0028] Deformation positioning element 4 is disposed between the two support elements 2 and its height is lower than that of the support elements 2;
[0029] The clamping device 3 is located between the two support members 2 and can compress the part of the angle steel member located between the two support members 2 to bend downward and abut against the deformation positioning member 4. Before welding, the deformation positioning member and the clamping device can cooperate to force the part of the angle steel member located between the two support members to bend downward by a predetermined arc, thereby balancing the overall bending deformation of the angle steel member caused by high temperature during the welding process and improving the welding quality.
[0030] The deformation positioning component 4 is mounted on the base 1 in an adjustable manner via a height adjustment assembly 5. This height adjustment assembly enables the deformation positioning component to move vertically, allowing precise control of the angle steel's bending curvature by adjusting its height. In use, adjusting the height of the deformation positioning component 4 adjusts the pre-bending curvature of the angle steel component, adapting to variations in deformation during welding due to different models, materials, and welding processes. This improves flexibility and expands its application range. In actual operation, the bending deformation of the angle steel component after welding under straight and fixed conditions is first determined. The height of the deformation positioning component 4 is then adjusted accordingly. The deformation positioning component 4, in conjunction with the clamping device 3, forces the pre-bending curvature of the angle steel component to deform precisely after welding, straightening the angle steel component.
[0031] like Figure 1 As shown, the height adjustment assembly 5 includes a lifting seat 5-1 and a lifting drive component 5-2 mounted on the base 1. The lifting seat 5-1 is located on the driving end of the lifting drive component 5-2 and can move up and down as the driving end of the lifting drive component 5-2 extends and shortens. The mechanical combination of the lifting drive component and the lifting seat forms a stable and reliable linear lifting mechanism. The lifting drive component 5-2 drives the lifting seat 5-1 to move vertically to adjust the height, and the height of the deformation positioning component 4 also changes along with the lifting seat 5-1. The height adjustment assembly has the advantages of simple structure, low cost, and easy adjustment. The above-mentioned guiding mechanism uses a combination of guide sleeve and guide post, but other existing guiding structures can also be used.
[0032] The lifting drive component 5-2 is one of a telescopic cylinder, a telescopic hydraulic cylinder, or an electric push rod. It uses a standardized power component (cylinder / hydraulic cylinder / electric push rod) as the core of the lifting drive, and has the characteristics of fast response and precise position control.
[0033] like Figure 1As shown, the base 1 is equipped with an end positioning assembly 7. The end positioning assembly 7 includes an end positioning seat 7-1 for positioning one end of the angle steel member against the end positioning seat 7-1 and an end positioning drive mechanism for pushing the angle steel member to move and abut against the end positioning seat 7-1. The end positioning assembly achieves precise lateral positioning of the angle steel member through active driving. When placing the angle steel member, it is only necessary to place the angle steel member on the two support members 2 within a certain range, and use the end positioning drive mechanism to push the angle steel member from the other end to move and abut against the end positioning seat 7. The end positioning of the angle steel member can be automatically completed without manual movement of the angle steel member, which can reduce the labor intensity and improve the placement efficiency.
[0034] The end positioning drive mechanism includes a pusher 7-2 and a telescopic drive 7-3 that drives the pusher 7-2 toward and away from the end positioning seat 7-1. When the telescopic drive 7-3 drives the pusher 7-2 toward the end positioning seat 7-1, it pushes the angle steel member from one end of the angle steel member to move and abut against the end positioning seat 7-1. When the telescopic drive 7-3 drives the pusher 7-2 away from the end positioning seat 7-1, it provides space for placing the angle steel member.
[0035] The support member 2 includes a support seat 2-1 disposed on the base 1 and a roller 2-2 rotatably fitted on the support seat 2-1. The roller-type support structure converts sliding friction into rolling friction, which greatly reduces the moving resistance of the angle steel.
[0036] The pressing device 3 includes a pressing block 3-1 and a cylinder 3-2 that drives the pressing block 3-1 to move up and down. The pressing device 3 is a prior art.
[0037] like Figure 2-3 As shown, the base 1 is also provided with an anti-deformation device 6. The anti-deformation device 6 includes a positioning plate 6-1 and an anti-deformation driving mechanism 6-2 that drives the positioning plate 6-1 to move between a first position and a second position. This can prevent the connecting parts that are connected to the angle steel body through the weld from changing angle relative to the angle steel body during the welding process, so that the product meets the design requirements and ensures the welding quality.
[0038] When the positioning plate 6-1 is in the first position, the positioning plate 6-1 simultaneously abuts against the connector 100 and the angle steel body 200 in the angle steel component. The connector 100 and the angle steel body 200 are relatively positioned by the positioning plate 81, thereby preventing the connector 100 from changing angle relative to the angle steel body 200 during the welding process. When the positioning plate 6-1 is in the second position, the positioning plate 6-1 disengages from the abutting engagement with the connector 100 and the angle steel body 200, which facilitates the loading and unloading of the angle steel component.
[0039] The above are merely preferred embodiments of this utility model. The scope of protection of this utility model is defined by the scope of the claims. Any improvements and modifications made by those skilled in the art without departing from the spirit and scope of this utility model should also be considered as protection within the scope of this utility model.
