Detailed Description
In order to describe the technical content and constructional features of the present invention in detail, the following description will be made with reference to the embodiments in conjunction with the accompanying drawings.
Referring to fig. 2 to 7, the method S100 for manufacturing a high-rigidity pulling arm of the present invention includes the following steps:
step S01: a steel bar 2, a sealing plate 3 and a welding gun are provided, and the welding gun adopts a spot welding mode to weld the steel bar 2 on the surface of the sealing plate 3, so that the steel bar 2 is connected with the sealing plate 3. Specifically, in this step, the number of welding spots 4 between the steel bar 2 and the sealing plate 3 is 2-3, the welding spots 4 are arranged at intervals around the circumference of the steel bar 2, and the steel bar 2 is welded at the center of the sealing plate 3. By means of spot welding between the steel bar 2 and the sealing plate 3, the subsequent steel bar 2 can easily fall off from the sealing plate 3 under the action of external force.
Step S02: providing a hollow drawing arm body 1 with two open ends, enabling a sealing plate 3 to face the opening of the drawing arm body 1, and extending a steel rod 2 and the sealing plate 3 into the drawing arm body 1; it can be understood that in this step, the sealing plate 3 is a thin plate, and the plane of the sealing plate 3 and the cross section of the drawing arm body 1 are parallel. The sealing plate 3 is arranged in the drawing arm body 1, so that the rigidity of the final drawing arm is improved, and the drawing arm can improve the load bearing capacity.
Step S03: providing a measuring tool 6, wherein one end of the measuring tool 6 extends into the interior of the drawing arm body 1 and is blocked on the sealing plate 3, and reading the numerical value on the measuring tool 6 at the moment, so as to obtain the position depth of the sealing plate 3 in the drawing arm body 1, and confirm the position of the sealing plate 3 at the moment; after the measurement is completed, the measuring tool 6 is taken out. Specifically, in this step, the measuring tool 6 is a tape measure, however, in other embodiments, the measuring tool 6 is a long ruler or a steel bar is provided with graduations, which is not limited thereto. During measurement, the tape is made to cling to the inner side wall of the drawing arm body 1, the head end of the tape is made to prop against the sealing plate 3, and the numerical value of the end opening of the tape, which is positioned at the end opening of the drawing arm body 1, is read, and is the current position reference of the sealing plate 3 in the drawing arm body 1. For example, assuming that the length of the pulling arm body 1 is 1000mm, the thickness of the sealing plates 3 is ignored, and 200mm is the distance between the two sealing plates 3, 4 sealing plates 3 (the sealing plates 3 at the openings at the two ends of the pulling arm body 1 are not counted) need to be built in. The tape measures 800mm from the end opening to the sealing plate 3 built in the interior of the pulling arm body 1. The position of the closure plate 3 can be adjusted and when the tape measure obtains a value of 800mm, this represents the correct position of the closure plate 3. Step S04: the welding gun stretches into the drawing arm body 1, and the welding gun adopts a segmented welding mode to weld four edges of the sealing plate 3 and four side faces of the drawing arm body 1 in a one-to-one correspondence mode. And after the welding is finished, taking out the welding gun, and cooling and waiting. Specifically, in this step, the welding lines 5 of the segment welding are 20-30mm, and the interval between two adjacent welding lines 5 is 40-60mm. By means of the welding mode of the sectional welding, the bending deformation caused by overheating of the inside of the drawing arm body 1 is prevented. The welding is firm, and meanwhile, the shape of the drawing arm body 1 is guaranteed not to be bent and deformed. For example, the sealing plate 3 is a square plate with a side length of 180mm.
Step S05: the steel bar 2 is knocked so that the steel bar 2 is separated from the sealing plate 3, and the steel bar 2 is taken out. Because the steel bar 2 and the sealing plate 3 are connected by adopting a spot welding mode, the steel bar 2 can be knocked off without using great force during the knocking process. And because the seal plate 3 and the drawing arm body 1 adopt the form of sectional welding, the welding is firm, so the steel bar 2 is beaten and the seal plate 3 cannot be displaced. It will be appreciated that in other embodiments, other removable connections between the steel bar 2 and the closure plate 3 may be used, such as snap fit, adhesive, etc.
Step S06: the above steps are repeated to locate the plurality of sealing plates 3 in the drawing arm body 1 at intervals. It will be appreciated that when proceeding to extend into the second closure plate 3, the value of the tape measure is 600mm and the position of the second closure plate 3 is not exactly calculated.
Step S07: providing two sealing plates 3, enabling one of the sealing plates 3 to cover an opening at one end of the drawing arm body 1, and welding the sealing plates 3 on the opening at one end of the drawing arm body 1 in a full-welding mode by using a welding gun; the other sealing plate 3 is covered on the opening at the other end of the drawing arm body 1, and the sealing plate 3 is welded on the opening at the other end of the drawing arm body 1 by using a welding gun in a full-welding mode. Because the sealing plates 3 at the openings at the two ends of the drawing arm body 1 can generate quicker heat exchange with the outside temperature, the full-welding mode can be adopted, the drawing arm body 1 cannot be affected by high temperature to generate bending deformation, and the welding is firmer.
Specifically, in this embodiment, the welding gun adopts a carbon dioxide arc welding mode, the voltage of the welding gun is 24-26V, and the current of the welding gun is 240-260A. Specific parameters of the welding gun are adjusted according to practical situations, namely the length and the thickness of the drawing arm body 1, the size and the thickness of the sealing plate 3, and therefore the welding gun is not limited to the specific parameters.
Referring to fig. 1 to 6, the pulling arm of the present invention is obtained by the above-mentioned manufacturing method. The drawing arm 200 comprises a drawing arm body 1 and a plurality of sealing plates 3, wherein the drawing arm body 1 is of a hollow structure with two open ends, the sealing plates 3 are of a thin plate structure, the sealing plates 3 are arranged in the drawing arm body 1 at intervals along the length direction of the drawing arm body 1, four edges of the sealing plates 3 are integrally connected with four inner side walls of the drawing arm body 1 in a welding mode, and the planes of the sealing plates 3 are parallel to the cross section of the drawing arm body 1. By means of the sealing plates 3 which are arranged in the drawing arm body 1, the rigidity of the drawing arm body 1 is enhanced, and the load bearing capacity of the drawing arm body 1 is improved. Preferably, in this embodiment, the sealing plates 3 are also welded to the openings at the two ends of the pulling arm body 1 to close the openings. The sealing plates 3 positioned at the two ends of the drawing arm body 1 are outer sealing plates, and welding seams between the outer sealing plates and the drawing arm body 1 are continuously arranged. It can be understood that the sealing plate 3 positioned inside the drawing arm body 1 is an inner sealing plate, and a plurality of welding seams 5 between the inner sealing plate and the drawing arm body 1 are arranged at intervals. For example, the length of the weld 5 is 20-30mm, and the distance between two adjacent weld 5 is 40-60mm, but not limited thereto. For example, in the present embodiment, the drawing arm body 1 is of a square-shaped sheet structure, and the sealing plate 3 is of a square-shaped sheet structure, however, in other embodiments, the drawing arm body 1 is of a flat-shaped structure, and the invention is not limited thereto.
Compared with the prior art, the manufacturing method of the high-rigidity drawing arm has the advantages that the plurality of sealing plates 3 which are distributed at intervals are arranged in the drawing arm body 1, and the rigidity of the drawing arm body 1 is enhanced by the aid of the sealing plates 3. Meanwhile, the method is simple to operate, the existing drawing arm body 1 is improved in technology at extremely low cost, and the effect of high rigidity can be achieved under the condition that the weight and the thickness of the drawing arm body 1 are not increased. Similarly, the drawing arm has the advantages of simple manufacturing process, low cost and high rigidity under the condition of not increasing the weight and thickness of the drawing arm. Meanwhile, the weight of the pulling arm is not excessively increased, and the energy consumption cost can be reduced.
