Description

Technical Field

[0001] This utility model belongs to the technical field of H-beam steel assembly welding and straightening integrated machine, and particularly relates to an H-beam steel assembly welding and straightening integrated machine with a clamping device. Background Technology

[0002] The H-beam assembly, welding, and straightening integrated machine is a specialized piece of equipment for H-beam production. It combines the traditional assembly, welding, and straightening processes into one integrated machine, primarily serving industries such as prefabricated buildings, steel structure workshops, light steel villas, bridges, shipbuilding, subways, high-speed railways, drilling platforms, gas furnaces, and weighbridges.

[0003] Currently, H-beam welding and straightening integrated machines rely solely on the upper rollers to press down the vertically arranged steel plates. When the vertical span of the vertically arranged steel plates is large, the limiting stability of the steel plates is poor, which in turn affects the welding accuracy. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated welding and straightening machine for H-beams with a clamping device in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an integrated welding and straightening machine for H-beams with a clamping device, comprising:

[0006] A support platform on which trusses are installed;

[0007] Multiple first support wheels are arranged in a rectangular array and hinged to the support platform;

[0008] Multiple second support wheels are arranged in a rectangular array and hinged to the truss;

[0009] A welding machine, which is fixedly mounted on the truss;

[0010] Two welding torches are symmetrically arranged and fixedly connected to the support platform, and the two welding torches are connected to the welding machine.

[0011] A clamping mechanism, which is slidably connected to the truss;

[0012] A first electric cylinder is arranged vertically and fixedly connected to the truss, and the first electric cylinder is connected to and drives the clamping mechanism.

[0013] As a further description of the above technical solution:

[0014] The clamping mechanism includes a support frame, two second electric cylinders and two third support wheels. The support frame is fixedly connected to the telescopic end of the first electric cylinder. A positioning groove is provided at the bottom of the support frame. The second electric cylinders are symmetrically arranged and fixedly connected to the support frame. The two third support wheels are respectively hinged to the telescopic ends of the two second electric cylinders, and both third support wheels are located inside the support frame.

[0015] As a further description of the above technical solution:

[0016] Both ends of the support frame abut against the truss.

[0017] As a further description of the above technical solution:

[0018] The rotation axis of the third support wheel is arranged vertically.

[0019] As a further description of the above technical solution:

[0020] The support frame is provided with a weight reduction groove, and both of the second electric cylinders are installed in the weight reduction groove.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] 1. In this utility model, multiple first support wheels abut against the opposite ends of a horizontal steel plate located on a support platform, providing guidance and support for the movement of the horizontal steel plate. Multiple second support wheels abut against the opposite sides of a vertical steel plate, providing guidance and support for the movement of the vertical steel plate. The pressing mechanism initially presses down on the vertical steel plate under the action of the first electric cylinder, and precisely presses and corrects the vertical steel plate. Even if the span of the vertical steel plate is large, the limiting stability of the vertical steel plate can be ensured, thereby guaranteeing the welding accuracy.

[0023] 2. In this utility model, the positioning groove abuts against the vertical steel plate, which plays a role in initial stabilization and support. The extension and retraction of the second electric cylinder drives the position change of the third support wheel, so that the third support wheel abuts against the side of the vertical steel plate. Even if the span of the vertical steel plate is large, the vertical steel plate can be stabilized and limited, and it also has the effect of correction, thereby ensuring the accuracy of welding.

[0035] Welding machine 5 is fixedly mounted on the truss 2;

[0036] Two welding torches 6 are arranged symmetrically and fixedly connected to the support platform 1, and the two welding torches 6 are connected to the welding machine 5;

[0038] The first electric cylinder 8 is arranged vertically and fixedly connected to the truss 2, and the first electric cylinder 8 is connected to and drives the clamping mechanism 7;

[0039] The clamping mechanism 7 includes a support frame 71, two second electric cylinders 72, and two third support wheels 73. The support frame 71 is fixedly connected to the telescopic end of the first electric cylinder 8. A positioning groove 9 is provided at the bottom of the support frame 71. The second electric cylinders 72 are symmetrically arranged and fixedly connected to the support frame 71. The two third support wheels 73 are respectively hinged to the telescopic ends of the two second electric cylinders 72, and both third support wheels 73 are located inside the support frame 71. The positioning groove 9 abuts against the vertical steel plate, which plays a role in initial stabilization and support. The telescopic movement of the second electric cylinders 72 causes the position of the third support wheels 73 to change, so that the third support wheels 73 abut against the side of the vertical steel plate. Even if the span of the vertical steel plate is large, it can limit and stabilize the vertical steel plate and also has the effect of correction, thereby ensuring the accuracy of welding.

[0040] Both ends of the support frame 71 abut against the truss 2, and the truss 2 provides guidance and support for the sliding of the support frame 71, ensuring the stability of the sliding of the support frame 71.

[0041] The rotation axis of the third support wheel 73 is arranged vertically, so that the third support wheel 73 can follow the direction of the vertical steel plate;

[0042] The support frame 71 is provided with a weight reduction groove 10, and the two second electric cylinders 72 are installed in the weight reduction groove 10, which makes the structure of the support frame 71 lighter.

[0043] Working principle: First, multiple first support wheels 3 abut against the opposite ends of the horizontal steel plate located on the support platform 1, providing guidance and support for the movement of the horizontal steel plate. Multiple second support wheels 4 abut against the opposite sides of the vertical steel plate, providing guidance and support for the movement of the vertical steel plate. Second, the positioning groove 9 abuts against the vertical steel plate, providing initial stabilization and support. The extension and retraction of the second electric cylinder 72 drives the position change of the third support wheel 73, causing the third support wheel 73 to abut against the side of the vertical steel plate. Even if the span of the vertical steel plate is large, it can limit and stabilize the vertical steel plate and also has a correction effect, thereby ensuring the welding accuracy. Finally, the welding machine 5 is turned on, and the welding torch 6 performs submerged arc welding on the gap between the horizontal and vertical steel plates.
