Description

Technical Field

[0001] The invention relates to the technical field of size correction devices, and in particular to an automatic correction device for size deformation after solid solution of stainless steel. Background Art

[0002] In order to improve the material structure and improve the performance of stainless steel, the pickled stainless steel capillary is usually subjected to solution treatment to make its structure a supersaturated solid solution or a solid solution phase that usually only exists at high temperatures. It is thermodynamically metastable and will undergo dissolution or other transformations under appropriate temperature or stress conditions.

[0003] However, after solution treatment, the release of residual stress, the generation of thermal stress and changes in the structure of the stainless steel plate will cause the size of some stainless steel plates to deform. For example, during the heating process, if one end of the stainless steel plate is heated faster and the other end is heated slower, thermal stress will be generated, causing the tube to bend. In addition, during the subsequent cooling process, if the flow of the cooling medium is uneven, similar bending deformation will also occur.

[0004] In the prior art, in order to correct the deformation of the steel plate, various correction and straightening devices are used. The principle is to apply pressure to the plate by pressing or using multiple rollers to gradually restore it to flatness. However, since the steel plate has a certain resilience, the effect of one straightening is often not good, and multiple straightenings are required, which seriously delays work efficiency. Summary of the invention

The plug 13 is fixedly connected, and the other end is connected to a push block 15. A second piston 16 is arranged in the second cylinder 12, a pull rope 17 is connected between the second piston 16 and the first piston 13, and a spring 18 is connected to the bottom of the second piston 16; a support block 19 is fixed on the top wall of the first cylinder 11 and the second cylinder 12; a connecting pipe 20 is connected between the first cylinder 11 and the second cylinder 12, and a valve 21 is installed on the connecting pipe 20, and an exhaust pipe 22 is connected to the bottom of the first cylinder 11; After the correction is completed, in order to facilitate the removal of multiple correction plates 601, during the correction, every time the driving rod 5 drops once, the connecting rod 9 drives the air pump 10 to inflate once, and the air enters the second cylinder 12 and squeezes the second piston 16 to drop and squeeze the spring 18. The second piston 16 pulls the first piston 13 up through the pull rope 17, so that the movable rod 14 and the push block 15 are raised for a distance, which will not affect the movement of the push plate 8. After multiple stainless steel plates are corrected, the push block 15 reaches the highest point. After the correction is completed, the valve 21 is opened, the second cylinder 12 is depressurized, and the air enters the first cylinder 11.

[0036] The working principle of the present invention is as follows: during operation, the bent steel plate is placed on the placement plate 2, and then the driving rod 5 and the correction mechanism 6 are driven downward by an external driving source, and the bottom correction plate 601 contacts the stainless steel plate to be squeezed and corrected. At the same time, the airbag 604 is squeezed after the correction plate 601 contacts the stainless steel plate until the pressure plate 605 is flush with the bottom of the correction plate 601. After the airbag 604 is squeezed, the gas enters the second installation groove through the connecting channel 608, thereby pushing the positioning plate 606, and the positioning plate 606 enters the positioning port of the baffle 3. At this time, the bottom correction plate 601 is in contact with the stainless steel plate. The plate 601 is fixed in order to keep the stainless steel plate in this state for a period of time so that the stress inside the plate can be fully released to avoid rebound. Then the driving rod 5 and the correction mechanism 6 are reset, and the bottom correction plate 601 is separated from the rest of the correction plates 601. The next bent steel plate is placed on the separated correction plate 601, and the above operation is repeated. When all the correction plates 601 are used up, the threaded connector 502 can be rotated to separate it from the correction plate 601, and the placement plate 2 can be moved aside and kept for a period of time, and a new placement plate 2 can be replaced to continue the correction operation;

[0037] Whenever the driving rod 5 descends once, the air pump 10 is driven to inflate once through the connecting rod 9. After the air enters the second cylinder 12, it squeezes the second piston 16 to descend. The second piston 16 pulls the first piston 13 up through the pull rope 17, so that the movable rod 14 and the push block 15 are raised for a distance, which will not affect the movement of the push plate 8. After multiple stainless steel plates are corrected, the push block 15 reaches the highest point. After maintaining for a period of time, the valve 21 is opened, and the second cylinder 12 is depressurized. Under the action of gravity, the push block 15 descends and pushes the push plate 8 from top to bottom in turn. The push plate 8 squeezes the positioning plate 606 into the correction plate 601 and the airbag 604 is reset, so that each correction plate 601 is automatically detached from the baffle 3, and the corrected stainless steel plate is taken away. Each correction plate 601 is automatically adsorbed together, and the threaded connector 502 is connected to the top correction plate 601.
