[0002] To improve the mechanical properties of titanium alloy plates, a composite heat treatment process of solid solution treatment and aging treatment is generally adopted in industry. However, due to factors such as technical conditions, equipment precision and process design, titanium alloy plates are prone to transverse bending defects such as wavy bending and edge waves during the rolling production stage. At the same time, uncontrollable plastic deformation of the plates may occur due to the release of internal residual stress during the solid solution treatment. In view of the above two types of deformation problems, special straightening equipment must be configured in the production process to accurately straighten the plates to ensure the geometric precision and dimensional stability of the final product.

[0003] The existing straightening equipment for titanium alloy plate strips has the following problems:

[0004] The existing titanium alloy plate strip straightening equipment does not have the ability to cool and shape the heated titanium alloy plate strip, which increases the probability of springback of the straightened titanium alloy plate strip, thereby increasing the number of roll pressing of the titanium alloy plate strip, thereby increasing the labor intensity of the workers, and the temperature difference between the end of the titanium alloy plate strip that is first heated and rolled and the end that is later heated and rolled is large, which causes different shrinkage degrees in different regions of the titanium alloy plate strip, resulting in residual stress in the titanium alloy plate strip, thereby reducing the quality of the titanium alloy plate strip after heating and straightening.

[0037] The side walls of the workbench 2 are provided with a controller 40.

[0038] The controller 40 is electrically connected with the driving motor 5, the heating coil 12, the hydraulic cylinder 18, the water supply pump 31, the flow valve 32 and the strip electromagnet 36 respectively.

[0039] In specific use, in the initial state, the copper straightening mesh roller 11 is placed above the middle part of the workbench 2, the torsion springs 24 arranged on the ends of the workbench 2 are in the twisted deformation state, and the copper straightening mesh roller 11 and the roller 39 are respectively attached to the upper wall of the straightening plate 19.

[0040] When the titanium alloy plate strip needs to be straightened, the controller 40 controls the hydraulic cylinder 18 to start, the power end of the hydraulic cylinder 18 shortens to drive the straightening plate 19 to descend, the straightening plate 19 moves away from the copper straightening net roller 11 and the roller 39, the controller 40 controls the driving motor 5 to start, the power end of the driving motor 5 drives the threaded rod 6 to rotate forward, the threaded rod 6 drives the driving frame 8 to move to one end of the workbench 2, the driving frame 8 drives the copper straightening net roller 11 to move through the sliding block 7 along the upper wall of the workbench 2, and the copper straightening net roller 11 reaches the end of the straightening plate 19. At this time, the torsional spring 24 near the copper straightening net roller 11 resets, and the temperature-resistant transmission belt 26 is wound outside the torsional roller 23. Since the distance between the roller 39 protruding from the surface of the temperature-resistant transmission belt 26 is greater than the distance between the thick and thin water-absorbing cotton layers 27 and 28 protruding from the surface of the temperature-resistant transmission belt 26, the temperature-resistant transmission belt 26 has a large space inside under the support of the magnetic frame 38 and the roller 39, thereby avoiding extrusion of the temperature-resistant transmission belt 26 on the thick and thin water-absorbing cotton layers 27 and 28; the torsional spring 24 far from the copper straightening net roller 11 continues to deform and twist, the length of the temperature-resistant transmission belt 26 unwound from the outside of the torsional roller 23 increases, and the temperature-resistant transmission belt 26 is laid flat above the straightening plate 19;

[0041] Cooling water is sprayed into the thick and thin water-absorbing cotton layers 27 and 28 wound outside the torsional roller 23, an external water pipe is communicated with the flow valve 32, the thick and thin water-absorbing cotton layers 27 and 28 wound outside the torsional roller 23 are moistened, the controller 40 controls the water supply pump 31 to start, the water supply pump 31 draws cooling water through the flow valve 32, the cooling water enters the inside of the water supply pipe 33, the water supply pipe 33 sprays the cooling water into the inside of the thin water-absorbing cotton layer 28, and the thick water-absorbing cotton layer 27 absorbs the cooling water in the thin water-absorbing cotton layer 28, so that the thick and thin water-absorbing cotton layers 27 and 28 store cooling water. When the flow of the cooling water drawn by the water supply pump 31 reaches the requirement of the operator, the controller 40 controls the water supply pump 31 to stop drawing cooling water;

[0042] When the titanium alloy plate strip is straightened, the controller 40 controls the heating coil 12 to start, the heating coil 12 is electrified to heat the metal rod 13, the metal rod 13 heats the copper straightening net roller 11, the titanium alloy plate strip to be straightened is sent to the upper wall of the straightening plate 19, one end of the titanium alloy plate strip is aligned with the end of the straightening plate 19, the controller 40 controls the hydraulic cylinder 18 to start, the power end of the hydraulic cylinder 18 is elongated to drive the straightening plate 19 to ascend, the straightening plate 19 drives the titanium alloy plate strip to be combined with the bottom wall of the copper straightening net roller 11, the copper straightening net roller 11 heated after heating heats the titanium alloy plate strip, and the roller 39 on the bottom wall of the temperature-resistant transmission belt 26 on the two sides of the copper straightening net roller 11 is combined with the upper wall of the titanium alloy plate strip;

[0043] The controller 40 controls the driving motor 5 to start, and the driving motor 5 drives the copper straightening net roller 11 to roll along the upper wall of the titanium alloy strip through the reverse rotation of the power end. The titanium alloy strip is heated and rolled by the copper straightening net roller 11, and the titanium alloy strip is prone to springback after being straightened. The heat pressing seat 42 pulls the temperature-resistant transmission belt 26 through the heat insulation frame 15. The temperature-resistant transmission belt 26 drives the twisting roller 23 to rotate along the outer side of the winding shaft 43 under the deformation of the torsional spring 24. The temperature-resistant transmission belt 26 is unwound from the outer side of the twisting roller 23 and laid on the upper side of the titanium alloy strip. The roller 39 unwound from the outer side of the titanium alloy strip is attached to the upper wall of the titanium alloy strip.

[0044] The copper straightening net roller 11 heats and rolls the titanium alloy strip on the upper wall of the straightening plate 19. The titanium alloy is prone to springback after being straightened. The heat pressing seat 42 pulls the temperature-resistant transmission belt 26 through the heat insulation frame 15. The temperature-resistant transmission belt 26 drives the twisting roller 23 to rotate along the outer side of the winding shaft 43 under the deformation of the torsional spring 24. The temperature-resistant transmission belt 26 is unwound from the outer side of the twisting roller 23 and laid on the upper side of the titanium alloy strip. The roller 39 unwound from the outer side of the titanium alloy strip is attached to the upper wall of the titanium alloy strip.

[0045] The controller 40 controls the driving motor 5 to start, and the driving motor 5 drives the copper straightening net roller 11 to roll along the upper wall of the titanium alloy strip through the reverse rotation of the power end. The titanium alloy strip is heated and rolled by the copper straightening net roller 11, and the titanium alloy strip is prone to springback after being straightened. The heat pressing seat 42 pulls the temperature-resistant transmission belt 26 through the heat insulation frame 15. The temperature-resistant transmission belt 26 drives the twisting roller 23 to rotate along the outer side of the winding shaft 43 under the deformation of the torsional spring 24. The temperature-resistant transmission belt 26 is unwound from the outer side of the twisting roller 23 and laid on the upper side of the titanium alloy strip. The roller 39 unwound from the outer side of the titanium alloy strip is attached to the upper wall of the titanium alloy strip.

[0046] With the movement of the driving motor 5 driving the heat pressing seat 42, the roller 39 and the copper straightening net roller 11 roll along the upper wall of the titanium alloy strip. The roller 39 is used for cooling and shaping the titanium alloy strip. Due to the setting of the high-temperature rubber heat preservation layer 29, the cooling water in the thick water-absorbing cotton layer 27 cannot contact the heated titanium alloy strip.

[0047] The thin water-absorbing cotton layer 28 cools and shapes the titanium alloy strip after being heated and rolled. The titanium alloy strip heats the cooling water in the thin water-absorbing cotton layer 28. The cooling water in the thin water-absorbing cotton layer 28 evaporates after being heated and absorbs the heat in the titanium alloy strip. After the original cooling water in the thin water-absorbing cotton layer 28 is evaporated, the cooling water in the thick water-absorbing cotton layer 27 with high humidity enters the thin water-absorbing cotton layer 28 with low humidity, thereby continuously cooling and shaping the titanium alloy strip after being heated and rolled.

[0048] The controller 40 controls the power end of the driving motor 5 to switch the movement of the positive and negative rotation. Through repeated heating and cooling of the titanium alloy strip, the springback amount of the titanium alloy strip after being heated and straightened is reduced, and the shape of the titanium alloy strip after being straightened is closer to the target shape.

[0049] When the temperature-resistant transmission belt 26 laid on the upper side of the titanium alloy strip is completely wound on the outer side of the twisting roller 23, the controller 40 controls the water supply pump 31 to spray cooling water into the thick water-absorbing cotton layer 27 and the thin water-absorbing cotton layer 28 through the nozzle 34. The flow valve 32 monitors the flow of the cooling water to ensure the consistency of the cooling of the heated titanium alloy strip.

[0050] And the copper straightening net roller 11 is heated to the titanium alloy plate strip on the upper wall of the straightening plate 19, and the temperature-resistant conveying belt 26 and the high-temperature rubber heat preservation layer 29 are laid on the titanium alloy plate strip, which can reduce the heat loss of the titanium alloy plate strip after rolling, reduce the temperature difference between the two ends of the titanium alloy plate strip, reduce the probability of internal residual stress, and ensure the quality of the titanium alloy plate strip after heating and straightening operation;

[0051] When the number of reciprocating rolling of the copper straightening net roller 11 to the titanium alloy plate strip reaches the specified number of the operator, the controller 40 controls the hydraulic cylinder 18 to start, the power end of the hydraulic cylinder 18 shortens to drive the titanium alloy plate strip to descend, the titanium alloy plate strip moves away from the copper straightening net roller 11, and a new group of titanium alloy plate strips to be straightened is sent to the upper wall of the straightening plate 19; the above operation can be repeated next time.
