Description

Technical Field

[0001] The present invention relates to a steel sheet pile technology, in particular to a production technology of special-shaped steel sheet piles, specifically a welding tool for Y-shaped steel sheet pile components in 3Y-shaped steel sheet piles. Background Art

[0002] At present, the steel sheet pile technology, as an efficient and environmentally friendly temporary or permanent support structure, is widely used in civil engineering, water conservancy projects, port construction and other fields. Chinese patents 2010101882260, 201010188228X, 2010101882364, 2010101882398, etc. have comprehensively disclosed the general shapes and preparation methods of existing steel sheets. After decades of development, the main development direction of steel sheet piles is the application of high-strength steel: modern steel sheet piles mostly use high-strength low-alloy steels (such as S355, S420, etc.), which have both high bearing capacity and corrosion resistance. In some special environments, stainless steel or anti-corrosion coatings (such as epoxy coatings, galvanizing) are used. Its forming process is mainly cold bending forming technology. By cold bending process, cross-sections such as U-shaped, Z-shaped, and straight-shaped are produced to improve the bending and shear resistance of the pile body. Laser welding technology can also be used to improve the joint strength. And lightweight design is becoming the development direction of many production enterprises, that is, under the premise of protecting strength and moment of inertia, the steel consumption is minimized as much as possible to achieve green development. At present, the optimized cross-sectional shapes mainly include "hat-shaped" and "box-shaped" cross-sections. Although they have partially solved the problems of lightweight, reduced construction difficulty and transportation cost, they still have complex structures, high manufacturing costs, and require the development of special equipment to mass-produce, making it difficult to be widely promoted. Therefore, the steel sheet pile technology is developing towards high strength, intelligence, and greenness, and has great potential in deep-sea engineering, urban underground space development and other fields in the future. However, cost control, adaptability to complex geology, and full-life cycle management are still the key points that the industry needs to break through. For this reason, designing a 3Y-shaped steel sheet pile can well solve the above problems. And the welding forming of the Y-shaped steel sheet pile, which is the basic component of the 3Y-shaped steel sheet pile, is the key to the production of the entire 3Y-shaped steel sheet pile. The Y-shaped steel sheet pile is usually welded by a V-shaped steel sheet 7 and a straight-shaped steel sheet 12. Since its length usually reaches dozens of meters, ordinary welding means are difficult to meet the production needs and ensure the welding quality. It is necessary to use a numerically controlled welding manipulator for welding. In order to meet the needs of the numerically controlled welding manipulator, a corresponding welding tool must be designed to meet the production needs. Summary of the Invention

[0003] The purpose of the present invention is to design a welding tool for Y-shaped steel sheet piles in view of the problem that the Y-shaped steel sheet piles in the existing 3Y-shaped steel sheet piles lack a welding tool that meets the needs of numerically controlled welding manipulators and are difficult to carry out.

[0004] The technical solution of the present invention is as follows: A Y-shaped steel sheet pile welding tooling, characterized in that: it includes a deformation prevention platform 4, on which an inverted V-shaped boss 7 is fixed, and on both sides of the V-shaped boss 7, a downward pressure type quick clamp 2 for pressing the V-shaped steel sheet 6 and a push-pull type quick clamp 5 for pressing the straight-shaped steel sheet 12 are installed; the deformation prevention platform 4 is clamped between the active pneumatic clamp 8 and the passive pneumatic clamp 1, the active pneumatic clamp 8 is installed on the fixed bracket 11 and connected to the motor 9 that drives its rotation, and the passive pneumatic clamp 1 is installed on the moving bracket 10, and the moving bracket 10 is installed on the moving platform 13 for its movement.

[0005] The motor 9 is directly or through a reduction mechanism connected to the active pneumatic clamp 8.

[0006] The moving bracket 10 is provided with a locking mechanism so as to remain stationary after it is adjusted in place.

[0007] The deformation prevention platform 4 rotates positively and negatively by 60 degrees driven by the active pneumatic clamp 8 to facilitate the operation of the welding torch 15.

[0008] When fixing the V-shaped steel sheet 6 and the straight-shaped steel sheet 12, the deformation prevention platform 4 is installed on the pre-installation bracket 4, and a push-pull type quick clamp 5 and a downward pressure type quick clamp 2 for positioning them in the length direction are respectively installed at both ends of the deformation prevention platform 4 corresponding to the V-shaped steel sheet 6 and the straight-shaped steel sheet 12.

[0009] The V-shaped steel sheet 6 and the straight-shaped steel sheet 12 are first spot-welded on the pre-installation bracket 4, then the push-pull type quick clamp 5 and the downward pressure type quick clamp 2 at both ends are removed, and then they are integrally clamped between the active pneumatic clamp 8 and the passive pneumatic clamp 1 and rotated positively and negatively by 60 degrees to complete the welding of two weld seams.

[0010] The beneficial effects of the present invention: The present invention solves the urgent production need, has the advantages of simple structure, convenient manufacturing and installation, can greatly improve the production efficiency, and can meet the batch production needs of 3 Y-shaped steel sheet piles.

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] As Figure 7 shown.

[0020] The present invention is a welding device used for producing any one of the Y-shaped steel sheet piles in the Figure 7 shown 3Y-shaped steel sheet pile. The production of the V-shaped steel plate 7 and the straight-shaped steel plate 12 that make up the Y-shaped steel sheet pile 3 is not within the scope of discussion of the present invention and can be implemented with reference to existing descriptions or the applicant's similar patents. It should be noted that the numerically controlled welding manipulator (model number can be GLLMH-350) and the down-pressing type quick clamp used in the present invention can be designed by oneself or directly adopt the commercially available product with the model number: BRH-102B. The horizontal push-pull type quick clamp can also be designed by oneself or directly adopt the commercially available product with the model number GH-305-HM. The active pneumatic clamp 8 and the passive pneumatic clamp 1 used during the welding process can be directly ordered from the market or designed and manufactured by oneself with reference to relevant manuals. The present invention will not describe their structures but directly adopt them. At the same time, they can also be designed and manufactured according to technical terms.

[0021] As Figures 1-6 shown.

[0022] A welding tooling for Y-shaped steel sheet piles, which includes a deformation prevention platform 4. A reverse V-shaped boss 7 is fixed on the deformation prevention platform 4 (as Figure 5 , 6 ). A down-pressing type quick clamp 2 for pressing the V-shaped steel plate 6 and a push-pull type quick clamp 5 for pressing the straight-shaped steel plate 12 are installed on both sides of the V-shaped boss 7; the deformation prevention platform 4 is clamped between the active pneumatic clamp 8 and the passive pneumatic clamp 1. The active pneumatic clamp 8 is installed on the fixed bracket 11 and is connected to the motor 9 that drives its rotation. The motor 9 can be directly (a stepping motor or a rotary angle motor can be used) or connected to the active pneumatic clamp 8 through a reduction mechanism. The passive pneumatic clamp 1 is installed on the moving bracket 10, and the moving bracket 10 is installed on the moving platform 13 for its movement. The moving bracket 10 is provided with a locking mechanism so as to keep still after it is adjusted in place. As Figure 1 , 2As shown. The anti-deformation platform 4 is driven by the active pneumatic clamp 8 to rotate positively and negatively by 60 degrees to facilitate the operation of the welding torch 15, such as Figure 3 .

[0023] When fixing the V-shaped steel plate 6 and the straight-shaped steel plate 12, the anti-deformation platform 4 is installed on the pre-installed bracket 4. A push-pull type quick clamp 5 and a push-down type quick clamp 2 for positioning them in the length direction are respectively installed at both ends of the anti-deformation platform 4 corresponding to the V-shaped steel plate 6 and the straight-shaped steel plate 12. Such as Figure 4 . The V-shaped steel plate 6 and the straight-shaped steel plate 12 are first spot-welded on the pre-installed bracket 4, then the push-pull type quick clamp 5 and the push-down type quick clamp 2 at both ends are removed, and then the whole is clamped and rotated positively and negatively by 60 degrees between the active pneumatic clamp 8 and the passive pneumatic clamp 1 to complete the welding of two weld seams.

[0024] The manufacturing process of the present invention is as follows: First, the steel coil meeting the performance requirements purchased from the market is fed into the loading machine and then into the uncoiler for uncoiling; Secondly, the uncoiled steel plate is fed into the leveling machine for leveling; Thirdly, the leveled steel plate is fed into the numerical control shearing machine and transversely sheared into pieces according to the length for standby.

[0025] Fourthly, the sheared steel plate is longitudinally sheared again into a wide steel plate and a narrow steel plate according to the dimensions of the three parts of the Y-shaped steel plate. The transverse width of the wide steel plate is equal to the sum of the widths of the two inclined plates of the Y-shaped steel sheet pile, and the width of the narrow steel plate matches the vertical height of the Y-shaped steel sheet pile; Fifthly, the wide steel plate pile is fed into the bending machine for bending to form the V-shaped steel plate 6, and the included angle of the V-shaped steel plate 6 matches the upper included angle of the Y-shaped steel plate; Sixthly, the V-shaped steel plate 6 is inverted and fixed on the inverted V-shaped boss 7 through the push-down type clamp 2. As Figure 5 shown, the included angle of the inverted V-shaped boss 7 matches the included angle of the V-shaped steel plate. Then, another straight-shaped steel plate 12 is vertically installed on the upper part of the inverted V-shaped boss 7 by using the horizontal push-pull type clamp 5 and the two are made to contact; As Figure 6 shown.

[0026] Seventhly, the V-shaped steel plate 6 and the straight-shaped steel plate 12 are spot-welded by using a CO2 shielded welding machine to form a preliminarily formed integral Y-shaped structure; The anti-deformation platform 4 together with the assembled workpiece is taken down for standby. Then the anti-deformation platform 4 is installed between the active pneumatic clamp 8 and the passive pneumatic clamp 1.

[0027] Eighthly, drive the anti-deformation platform 4 to rotate 60° to the right ( Figure 6After that, a flanged weld bead is formed, and the first continuous welded seam is welded by submerged arc welding using the gantry numerically controlled welding manipulator 15. Then, the anti-deformation platform is rotated 60° to the left to form a flanged weld bead, and the second continuous welded seam is welded by submerged arc welding using the gantry numerically controlled welding manipulator 15. After the welding of the weld seam is completed, the passive pneumatic clamp 1 is loosened, the active pneumatic clamp 9 is loosened, and the anti-deformation platform 4 together with the welded workpiece is removed.

[0028] Parts not involved in the present invention are the same as or can be implemented using the prior art.
