Description

Technical Field

[0001] This utility model relates to a steel sheet pile technology, and more particularly to a production technology for irregularly shaped steel sheet piles, specifically a welding fixture for the Y-shaped steel sheet pile component in a 3Y-shaped steel sheet pile. Background Technology

[0002] Currently, 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 such as 2010101882260, 201010188228X, 2010101882364, and 2010101882398 comprehensively disclose the general shapes and manufacturing methods of existing sheet piles. After decades of development, the main direction of sheet pile development has been the application of high-strength steel: modern sheet piles mostly use high-strength low-alloy steel (such as S355 and S420), which combines high load-bearing capacity and corrosion resistance. In some special environments, stainless steel or anti-corrosion coatings (such as epoxy coatings and galvanizing) are used. Its forming process mainly involves cold bending, producing U-shaped, Z-shaped, and straight sections to improve the bending and shear resistance of the pile. Laser welding technology can also be used to improve joint strength. Lightweight design is becoming a development direction for many manufacturers, aiming to minimize steel usage while protecting strength and moment of inertia, thus achieving green development. Currently, optimized cross-sectional shapes mainly include "cap-shaped" and "box-shaped" sections. While these partially achieve lightweighting and reduce construction difficulty and transportation costs, they still suffer from complex structures, high manufacturing costs, and the need for specialized equipment for mass production, hindering large-scale promotion. Therefore, sheet pile technology is developing towards high strength, intelligence, and green technology, with huge potential in deep-sea engineering and urban underground space development. However, cost control, adaptability to complex geological conditions, and full life-cycle management remain key areas for the industry to overcome. Therefore, designing a 3Y-shaped steel sheet pile can effectively solve the above problems. The welding and forming of the Y-shaped steel sheet pile, which is the foundation component of the 3Y-shaped steel sheet pile, is the key to the entire production of the 3Y-shaped steel sheet pile. The Y-shaped steel sheet pile is usually welded by V-shaped steel plate 7 and I-shaped steel plate 12. Since its length is usually tens of meters, ordinary welding methods are difficult to meet production needs and ensure welding quality. CNC welding robots must be used for welding. In order to meet the needs of CNC welding robots, corresponding welding fixtures must be designed to meet production needs. Utility Model Content

[0003] The purpose of this invention is to address the problem that existing Y-shaped sheet piles lack welding fixtures that meet the requirements of CNC welding robots, making them difficult to weld, and to design a welding fixture for Y-shaped sheet piles.

[0004] The technical solution of this utility model is:

[0005] A Y-shaped sheet pile welding fixture is characterized by comprising an anti-deformation platform 4, on which an inverted V-shaped boss 7 is fixed, and on both sides of the V-shaped boss 7 are a downward-pressing quick clamp 2 for pressing the V-shaped steel plate 6 and a push-pull quick clamp 5 for pressing the straight steel plate 12; the anti-deformation platform 4 is clamped between an active pneumatic clamp 8 and a passive pneumatic clamp 1, the active pneumatic clamp 8 is mounted on a fixed bracket 11 and connected to a motor 9 that drives its rotation, the passive pneumatic clamp 1 is mounted on a movable bracket 10, and the movable bracket 10 is mounted on a movable platform 13 for its movement.

[0006] The motor 9 is directly or through a reduction mechanism connected to the active pneumatic clamp 8.

[0007] The movable support 10 is equipped with a locking mechanism so that it remains stationary once it is adjusted into place.

[0008] The anti-deformation platform 4 rotates ±60 degrees with the active pneumatic clamp 8 to utilize the operation of the welding torch 15.

[0009] When fixing the V-shaped steel plate 6 and the straight steel plate 12, the deformation prevention platform 4 is installed on the pre-installed bracket 14. A push-pull quick clamp 5 and a press-down quick clamp 2 are respectively installed on the deformation prevention platform 4 at both ends of the V-shaped steel plate 6 and the straight steel plate 12 to position them in the length direction.

[0010] The V-shaped steel plate 6 and the straight steel plate 12 are first spot welded on the pre-installed bracket 14. Then, the push-pull quick clamp 5 and the downward quick clamp 2 at both ends are removed. The whole plate is then clamped between the active pneumatic clamp 8 and the passive pneumatic clamp 1 and rotated 60 degrees in both directions to complete the welding of the two seams.

[0011] The beneficial effects of this utility model are:

It should be noted that the CNC welding robot (model can be GLMH-350) and the downward-pressing quick clamp used in this utility model can be designed by oneself or directly adopt the commercially available product model BRH-102B. The horizontal push-pull quick clamp can also be designed by oneself or directly adopt the commercially available product model GH-305-HM. The active pneumatic clamp 8 and the passive pneumatic clamp 1 used in the welding process can be directly ordered from the market or designed and manufactured by oneself with reference to relevant manuals. Their structures are not described in this utility model but are directly adopted. At the same time, they can also be designed and manufactured by oneself according to technical terminology.

[0023] like Figure 1-6 As shown.

[0024] A Y-shaped sheet pile welding fixture includes an anti-deformation platform 4, on which an inverted V-shaped boss 7 (e.g., ...) is fixed. Figure 5 , 6The V-shaped boss 7 has a downward-pressing quick clamp 2 for pressing the V-shaped steel plate 6 and a push-pull quick clamp 5 for pressing the straight steel plate 12 on both sides. The deformation-preventing platform 4 is clamped between the active pneumatic clamp 8 and the passive pneumatic clamp 1. The active pneumatic clamp 8 is mounted on a fixed bracket 11 and connected to a motor 9 that drives its rotation. The motor 9 can be directly connected to the active pneumatic clamp 8 (either a stepper motor or a rotary motor) or through a reduction mechanism. The passive pneumatic clamp 1 is mounted on a movable bracket 10, which is mounted on a movable platform 13 for its movement. The movable bracket 10 has a locking mechanism to keep it stationary after adjustment. Figure 1 , 2 As shown. The anti-deformation platform 4 rotates 60 degrees positively and negatively with the active pneumatic clamp 8 to utilize the operation of the welding torch 15, such as... Figure 3 .

[0025] When fixing the V-shaped steel plate 6 and the straight steel plate 12, the deformation prevention platform 4 is installed on the pre-installed bracket 14. A push-pull quick clamp 5 and a press-down quick clamp 2, which position the V-shaped steel plate 6 and the straight steel plate 12 respectively at both ends of the deformation prevention platform 4, are installed to position them in the length direction. Figure 4 The V-shaped steel plate 6 and the straight steel plate 12 are first spot welded on the pre-installed bracket 14. Then, the push-pull quick clamp 5 and the downward quick clamp 2 at both ends are removed. The whole plate is then clamped between the active pneumatic clamp 8 and the passive pneumatic clamp 1 and rotated 60 degrees in both directions to complete the welding of the two seams.

[0026] The manufacturing process of this utility model is as follows:

[0027] First, steel coils that meet the performance requirements purchased from the market are fed into the feeding machine, and then into the uncoiler for uncoiling.

[0028] Secondly, the uncoiled steel plate is fed into a leveling machine for leveling;

[0029] Third, the leveled steel plate is sent to a CNC shearing machine and cut into blocks according to length for later use.

[0030] Fourth, the cut steel plate is longitudinally cut 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.

[0031] Fifth, the wide steel sheet pile is fed into a bending machine for bending to form a V-shaped steel plate 6, the included angle of the V-shaped steel plate 6 matching the upper included angle of the Y-shaped steel plate;

[0032] Sixth, after inverting the V-shaped steel plate 6, it is fixed to the inverted V-shaped boss 7 using the downward clamping fixture 2, as shown. Figure 5As shown, the included angle of the inverted V-shaped boss 7 matches the included angle of the V-shaped steel plate. Then, using the horizontal push-pull clamp 5, another straight steel plate 12 is vertically installed on the upper part of the inverted V-shaped boss 7, bringing the two into contact. Figure 6 As shown.

[0033] Seventh, use a CO2 shielded welding machine to spot weld the V-shaped steel plate 6 and the straight steel plate 12 to form a preliminary integral Y-shaped structure; remove the anti-deformation platform 4 along with the assembled workpiece for later use. Then install the anti-deformation platform 4 between the active pneumatic clamp 8 and the passive pneumatic clamp 1.

[0034] Eighth, drive the anti-deformation platform 4 to rotate 60° to the right ( Figure 6 After forming a boat-shaped weld bead, the first continuous weld bead is welded using a gantry CNC welding robot 15 via submerged arc welding. Then, the anti-deformation platform is rotated 60° to the left to form another boat-shaped weld bead, and the second continuous weld bead is welded using the gantry CNC welding robot 15 via submerged arc welding. Once the weld is complete, the passive pneumatic clamp 1 is released, the active pneumatic clamp 9 is released, and the anti-deformation platform 4, along with the welded workpiece, is removed.
