Description

Technical Field

[0001] The utility model relates to the technical field of angle steel welding equipment, in particular to an angle steel flange welding device. Background Art

[0002] Angle steel, commonly known as angle iron, is a long steel strip with two perpendicular sides forming an angle. It can be divided into equal-leg angle steel and unequal-leg angle steel. Equal-leg angle steel has two sides of equal width. Angle steel can be used to form various load-bearing components according to different structural needs, and can also serve as connectors between components. Angle steel plays an important role in pipe connections, equipment mounting, structural support, and mechanical component connections. Its basic shapes are two main types: round flanges and square flanges. When processing square angle steel flanges, welding equipment is typically used to butt-fix four angle steels and then weld them together.

[0003] Existing angle steel flange welding devices have poor fixing effects on angle steels, and are prone to angle steel movement and dislocation during welding, resulting in uneven butt joints between angle steels and reduced butt joint quality, thus affecting welding results. For example, the utility model patent application number 202220916449.2 discloses an angle steel flange welding machine for angle steel flange processing. Although the active material and waste generated by the welding head can be blocked by a baffle, they fall into the water tank through the waste hole on the operating table. The water in the water tank can cool the high-temperature waste, thereby avoiding damage to the machine caused by waste splashing, while also ensuring the safety of the user during work.

[0004] However, the welding machine only fixes the angle steel by means of a fixing block and a baffle plate provided on the top of the operating table. The fixing effect is poor and the movement or dislocation of the angle steel during welding cannot be avoided. In addition, since the positions of the fixing block and the baffle plate are fixed, only one specification of angle steel flange can be welded, which makes the welding machine have certain limitations when used.

[0005] Therefore, it is necessary to develop an angle steel flange welding device to address the above defects. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0027] In one embodiment, Figure 1 As shown, it includes a base 1 and a welding part 2 fixedly installed at one end of the top surface of the base 1, a first slide groove 3 is provided on the top surface of the base 1, and moving blocks 4 are slidably connected at both ends of the first slide groove 3, and the tops of the two moving blocks 4 are fixedly connected with L-shaped fixing blocks 5, and the two L-shaped fixing blocks 5 are symmetrically arranged and the openings are opposite to each other; the bottom end of the L-shaped fixing block 5 is provided with a slot 7 for inserting two angle steels 6 required for welding; a first positioning component 8 and a second positioning component 9 are provided on the L-shaped fixing block 5, the first positioning component 8 is used to fix the top ends of the two angle steels 6, and the second positioning component 9 is used to press and fix the top surfaces of the parts of the two angle steels 6 inserted into the slots 7; a driving member is connected to the moving block 4, and the driving member is used to drive the two moving blocks 4 to move linearly in a direction approaching or away from each other at the same time.

[0028] By setting the L-shaped fixing block 5 and the slot 7, one side of the two angle steels 6 at the same welding position can be inserted into the slot 7 respectively, while the other sides of the two angle steels 6 are respectively fitted with the side walls of the L-shaped fixing block 5, and one end of one angle steel 6 is pressed against the side wall of the L-shaped fixing block 5, while one end of the other angle steel 6 is pressed against its side wall. Then, the two angle steels 6 are fixed by multiple limiting positions through the first positioning component 8 and the second positioning component 9, thereby improving the fixing effect of the angle steels 6 and avoiding movement and dislocation during welding, which affects the welding effect. At the same time, the two movable blocks 4 are driven to move by the driving member, further driving the two L-shaped fixing blocks 5 to move linearly in the direction of approaching or moving away from each other at the same time, so that angle steels 6 of different sizes can be fixed, thereby improving the practicality of the device.

[0029] In one embodiment, Figure 2 and Figure 3 As shown, the first positioning assembly 8 includes a first motor 801, the interior of the L-shaped fixed block 5 is hollow, the first motor 801 is fixedly connected to the top surface of the L-shaped fixed block 5, the output end of the first motor 801 is coaxially fixedly connected to the first threaded rod 802, and the other end of the first threaded rod 802 is rotatably connected to the bottom surface of the inner cavity of the L-shaped fixed block 5; an L-shaped movable plate 803 is threadedly connected to the first threaded rod 802, and the L-shaped movable plate 803 is slidingly connected to the side wall of the inner cavity of the L-shaped fixed block 5; second sliding grooves 804 are vertically opened on the two side walls of the L-shaped fixed block 5, and the two ends of the L-shaped fixed block 5 are fixedly connected to the first pressure plates 805, and the two first pressure plates 805 respectively pass through the two second sliding grooves 804 and are slidably connected thereto.

[0030] The forward or reverse rotation of the first motor 801 can drive the rotation of the first threaded rod 802, and further drive the L-shaped movable plate 803 to slide up and down in the inner cavity of the L-shaped fixed block 5, so that the first pressure plates 805 at both ends of the L-shaped movable plate 803 can slide up and down in the second slide groove 804, thereby achieving the compression, fixation and release of the top ends of the two angle steels 6 below it.

[0031] Specifically, two ends of the inner cavity bottom surface of the L-shaped fixed block 5 are fixedly connected with the sliding rods 806 , and two ends of the L-shaped movable plate 803 are slidably connected with the sliding rods 806 .

[0032] By setting the sliding rod 806, the L-shaped movable plate 803 can be slidably guided.

[0033] Specifically, the second positioning assembly 9 includes two telescopic parts 901, which are respectively fixedly connected to the side walls at both ends of the L-shaped fixing block 5. The telescopic ends of the telescopic parts 901 are vertically facing the base 1 and the top is fixedly connected to the second pressure plate 902.

[0034] The telescopic member 901 can be extended and retracted to drive the second pressing plate 902 to press toward or away from the top surface of the side where the angle steel 6 is inserted into the slot 7, thereby pressing, fixing, and releasing the angle steel 6.

[0035] Specifically, the bottom surfaces of the first pressing plate 805 and the second pressing plate 902 are fixedly connected with anti-skid rubber pads 903. This can increase the friction between the first pressing plate 805 and the second pressing plate 902 and the surface of the angle steel 6, preventing the angle steel 6 from sliding.

[0036] Specifically, the telescopic member 901 is an electric push rod, an electro-hydraulic push rod, a hydraulic cylinder or a pneumatic cylinder.

[0037] In one embodiment, Figure 4 As shown, the driving member includes a bidirectional threaded rod 10, which is rotatably connected to the side wall of the first slide groove 3, and the two moving blocks 4 are respectively threadedly connected to the left-handed thread and the right-handed thread of the bidirectional threaded rod 10. A second motor 11 is fixedly connected to the side wall of the base 1, and the output end of the second motor 11 is coaxially fixedly connected to one end of the bidirectional threaded rod 10.

[0038] In one embodiment, the bottom surface of the slot 7 and the top surface of the base 1 are located at the same horizontal plane, and the distance between the top and bottom surfaces of the slot 7 is greater than the side thickness of the angle steel 6. This allows the base 1 to support the remaining portion of the angle steel 6 when one end of the angle steel 6 is inserted into the slot 7.

[0039] Working principle of the present invention: When the angle steel flange welding device of the present invention is used, first, the bottom edges of both ends of an angle steel 6 are respectively inserted into the slots 7 of the L-shaped fixing blocks 5 at both ends of the first slide groove 3, so that the other side walls of the angle steel 6 are respectively fitted with one side wall of the two L-shaped fixing blocks 5, and the two ends of the angle steel 6 are respectively in contact with the other side wall of the L-shaped fixing blocks 5, and the two telescopic parts 901 above the angle steel 6 are controlled to extend, and the second pressing plate 902 is driven to move downward to press and fix the bottom edge of the angle steel 6; then the other two angle steels 6 are respectively inserted into the slots 7 of the two L-shaped fixing blocks 5, at this time, the two angle steels 6 are respectively perpendicular to the other angle steel 6, and then the telescopic parts 901 above the two angle steels are started to press and fix them;

[0040] Then start the first positioning assembly 8, and the first motor 801 starts working, driving the first threaded rod 802 to rotate. Since the L-shaped movable plate 803 is threadedly connected to the first threaded rod 802 and is guided by the second slide 804 and the slide rod 806, the L-shaped movable plate 803 will move up and down along the threaded rod. As the L-shaped movable plate 803 descends, the first pressure plates 805 at both ends thereof will press the top of the angle steel 6, further pressing and fixing the angle steel 6 fixed by the second positioning assembly 9, and then use the welding piece 2 to weld the joint of the angle steel 6 to complete the welding of one end of the angle steel flange. Take out the welded angle steel flange, and weld the other end of the angle steel flange according to the above steps to complete the welding of the angle steel flange.

[0041] If welding angle steel flanges of different sizes is required, the distance between the two L-shaped fixing blocks 5 can be adjusted by a drive. Specifically, the second motor 11 is activated to rotate the bidirectional threaded rod 10. Since the two moving blocks 4 are respectively threadedly connected to the left-handed and right-handed threads of the bidirectional threaded rod 10, when the bidirectional threaded rod 10 rotates, the two moving blocks 4 will simultaneously move linearly toward or away from each other, thereby adjusting the distance between the L-shaped fixing blocks 5.

[0042] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Reference can be made to the common and similar parts between the various embodiments. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the method description.

[0043] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
