Description

Technical Field

[0001] The invention relates to the technical field of welding dies, in particular to a curved surface welding die device. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. It is a process in which two or more materials of the same or different types are connected into one through the combination and diffusion between atoms or molecules. Existing steel plates are plate-shaped steel materials that are cast by molten steel and pressed after cooling. They can be directly rolled or cut from wide steel strips. When the length or bending angle of the finished steel plate does not meet the processing requirements, the steel plate will be processed by welding to make it a steel plate that meets the processing requirements. At this time, multiple steel plates will be welded together to form an overall steel plate structure.

[0003] The conventional welding operation method is to place two steel plates on the same plane and weld them together with a welding gun. This welding method is used when both steel plates are straight and are directly placed on the table for welding. If a curved steel plate with an arc is to be welded, it is necessary to support the curved steel plate so that the welding positions are close to each other during welding. In actual operation, it is found that the welding position of the two curved steel plates is difficult to fix, and it is easy to offset, displace or slide during welding, which is not convenient for fixing the steel plates. The welding position is offset during welding, which will lead to poor welding effect. The welded parts of the steel plates are prone to cracking after welding and have a low service life.

[0021] Thirdly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0022] Please refer to Figures 1 - 4 As shown, an arc surface welding die pressing device provided by an embodiment of the present invention includes a pair of fixed frames 1, and a lifting plate 2 is slidably arranged inside the pair of fixed frames 1; A positioning component 3 is arranged inside the lifting plate 2. The bottom of the fixing frame 1 is fixedly connected with a base 4, and the top of the base 4 is fixedly connected with a placing seat 5. An arc-shaped groove 6 is formed at the top of the placing seat 5, a welding groove 7 is formed in the middle of the arc-shaped groove 6, and sliding grooves 8 are formed on both sides of the welding groove 7 inside the placing seat 5. A pair of clamping plates 9 are slidably arranged inside the sliding grooves 8.

[0023] When welding two arc-shaped steel plates, place the two arc-shaped steel plates in the arc-shaped groove 6 at the top of the placing seat 5, and fit and butt the welding joints of the two arc-shaped steel plates. Drive a pair of clamping plates 9 inside the sliding grooves 8 to move towards each other to fix the two sides of the arc-shaped steel plates. Then drive the positioning component 3 to descend through the lifting plate 2 inside the fixing frame 1, so that the positioning component 3 positions and fixes the tops of the two arc-shaped steel plates, thereby improving the stability of the two arc-shaped steel plates and preventing the two arc-shaped steel plates from displacing or sliding during welding.

[0024] Among them, preferably, the positioning component 3 includes a first double-shaft motor 31 arranged inside the lifting plate 2. Both ends of the first double-shaft motor 31 are fixedly connected with lead screws 32. A pair of moving blocks 33 are screwed on the lead screws 32. The bottom of the moving block 33 is fixedly connected with a fixing plate 34. An elastic steel plate 35 is fixedly connected to the bottoms of a pair of fixing plates 34. Sliders 36 are fixedly connected to the tops of the moving block 33 and the fixing plate 34. The outer sides of the sliders 36 are slidably connected with the inner wall of the lifting plate 2.

[0025] When the lifting plate 2 descends, the bottom of the elastic steel plate 35 is in contact with the top of the arc-shaped steel plate. Drive the lead screw 32 to rotate through the first double-shaft motor 31, so that the two moving blocks 33 drive the fixing plate 34 to move towards each other, changing the radian of the elastic steel plate 35. Thus, the arc of the elastic steel plate 35 can be adjusted according to the radian of the arc-shaped steel plate, so as to position and fix arc-shaped steel plates with different radians, improving the applicability of the device. When the moving block 33 and the fixing plate 34 move, the sliders 36 at their tops slide on the inner wall of the lifting plate 2 to guide and limit the moving block 33 and the fixing plate 34, improving the stability of the moving block 33 and the fixing plate 34 during movement.

[0026] Preferably, an electric push rod 10 is arranged at the top of the fixing frame 1. The ejector rod of the electric push rod 10 is fixedly connected with the top of the lifting plate 2. It is convenient to drive the lifting plate 2 to lift and lower through the electric push rod 10.

[0027] Preferably, a pair of guide rods 11 are inserted inside the fixing frame 1. The bottom of the guide rod 11 is fixedly connected with the top of the lifting plate 2.

[0028] During the lifting and lowering process of the lifting plate 2, the guide rod 11 slides inside the fixing frame 1 to guide and limit the lifting plate 2, improving the stability of the lifting plate 2 during lifting and lowering.

[0029] Preferably, a second biaxial motor 12 is arranged inside the placement seat 5. Both ends of the second biaxial motor 12 are fixedly connected with screw rods 13, and the outer sides of the screw rods 13 are in threaded connection with the inner walls of the clamping plates 9.

[0030] The second biaxial motor 12 drives the screw rods 13 to rotate, thereby driving the two clamping plates 9 to slide in the sliding grooves 8.

[0031] Preferably, guide blocks 14 are fixedly connected to both sides of the lifting plate 2, and guide grooves 15 which are matched with the guide blocks 14 are formed in both sides of the inner wall of the fixing frame 1.

[0032] When the lifting plate 2 is lifted or lowered, the guide blocks 14 on both sides of it slide in the guide grooves 15 to guide and limit both sides of the lifting plate 2, making the lifting plate 2 more stable when it is lifted or lowered.

[0033] The working principle of the present invention is as follows: when welding two arc-shaped steel plates, place the two arc-shaped steel plates in the arc-shaped grooves 6 at the top of the placement seat 5, and fit and dock the welding joints of the two arc-shaped steel plates. Through the pair of clamping plates 9 inside the sliding grooves 8 moving towards each other, fix both sides of the arc-shaped steel plates. When the lifting plate 2 descends, the bottom of the elastic steel plate 35 is in contact with the top of the arc-shaped steel plate. The first biaxial motor 31 drives the lead screw 32 to rotate, so that the two moving blocks 33 drive the fixing plate 34 to move towards each other, changing the radian of the elastic steel plate 35. Thus, the arc of the elastic steel plate 35 can be adjusted according to the radian of the arc-shaped steel plate, so as to position and fix arc-shaped steel plates with different radians, improve the applicability of the device, thereby improving the stability of the two arc-shaped steel plates and preventing the two arc-shaped steel plates from shifting or sliding during welding.

[0034] It should be understood that in the development process of any actual implementation, such as in any engineering or design project, a large number of specific implementation decisions can be made.
