[0001] The utility model relates to the technical field of titanium alloy bar production, and specifically relates to an acid pickling device for titanium alloy bars. Background Technique

[0002] The acid pickling process is an essential link in the production of titanium alloy bars. Its purpose is to dissolve the oxide layer on the surface of the titanium alloy bars through an acidic cleaning solution to generate metal salts soluble in water, thereby achieving the purpose of removing the oxide layer skin.

Specific embodiments

[0026] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0027] Embodiment 1:

[0028] Please refer to Figure 1 - Figure 2As shown in the figure, a pickling device for titanium alloy bars includes a pickling tank 1 and titanium alloy bars 2; the top end of the outer wall of the pickling tank 1 is open; the inner side wall of the pickling tank 1 is provided with a driving roller 3 and a driven roller 4, and both ends of the outer walls of the driving roller 3 and the driven roller 4 are rotatably connected to the opposite sides of the inner wall of the pickling tank 1 respectively, and the driving roller 3 and the driven roller 4 are in the same plane; the outer side wall of the titanium alloy bar 2 is slidably placed on the outer side walls of the driving roller 3 and the driven roller 4, and the bottom end of the outer side wall of the titanium alloy bar 2 is located between the driving roller 3 and the driven roller 4; one end of the outer wall of the driving roller 3 is fixedly connected with a rotating shaft I 5, and one end of the outer wall of the rotating shaft I 5 penetrates through the outer wall of the pickling tank 1 and is in transmission connection with a motor 6 located outside the pickling tank 1; bearings are hermetically arranged at the connection parts of both ends of the driven roller 4 and the inner side wall of the pickling tank 1; a pair of pickling rods 7 are arranged on the inner side wall of the pickling tank 1, and the titanium alloy bar 2 is located between the pair of pickling rods 7, and there is a gap between the pickling rod 7 and the titanium alloy bar 2; both ends of the outer walls of the pair of pickling rods 7 are rotatably connected to the opposite sides of the inner wall of the pickling tank 1 respectively, and the pair of pickling rods 7 are in the same plane; a group of brush hairs 8 are fixedly connected to the outer side walls of the pair of pickling rods 7; the length of the brush hairs 8 is greater than the gap between the pickling rod 7 and the titanium alloy bar 2 and less than the gap between the pickling rod 7 and the adjacent supporting roller; one end of the outer wall of the pickling rod 7 adjacent to the driving roller 3 is fixedly connected with a rotating shaft II 9, and one end of the outer wall of the pickling rod 7 far from the driving roller 3 is fixedly connected with a rotating shaft III 10, and one end of the outer walls of the rotating shaft II 9 and the rotating shaft III 10 both penetrate through the pickling tank 1 and are in transmission connection with the rotating shaft I 5. By placing the titanium alloy bar 2 between the driving roller 3 and the driven roller 4, at this time, the motor 6 drives the rotating shaft I 5 to rotate, and the rotating shaft I 5 drives the driving roller 3 to rotate, so that the rotation of the driving roller 3 causes the titanium alloy bar 2 located on the driving roller 3 to rotate. And due to the rotation of the rotating shaft I 5, the rotating shaft II 9 and the rotating shaft III 10 will be driven to rotate, thereby driving the pair of pickling rods 7 and the brush hairs 8 on the pickling rods 7 to rotate, so that the brush hairs 8 wash the titanium alloy bar 2 when rotating, thereby realizing the repeated cleaning of the titanium alloy bar 2. And one of the functions of the driving roller 3 and the driven roller 4 is to support the titanium alloy bar 2 to be cleaned, and the second function is to drive the titanium alloy bar 2 to rotate, so as to realize the cleaning of different positions of the titanium alloy bar 2. Through the cooperative rotation of the titanium alloy bar 2 and the cleaning rod in this application, the efficient cleaning of the titanium alloy bar 2 is realized, and the pickling efficiency and pickling effect of the pickling device for the titanium alloy bar 2 are greatly improved. The transmission methods between the motor 6 and the rotating shaft I 5, between the rotating shaft I 5 and the rotating shaft II 9, and between the rotating shaft I 5 and the rotating shaft III 10 are one of chain drive, belt drive, and gear drive. Because a group of ultrasonic vibration rods 11 are fixedly connected to the bottom end of the inner side wall of the pickling tank 1;An ultrasonic generator 12 is provided outside the pickling tank 1. The ultrasonic vibration rod 11 is connected to the ultrasonic generator 12 through a connecting wire. The shock waves generated during the transmission of the ultrasonic waves emitted by the ultrasonic vibration rod 11 make the dirt and impurities on the titanium alloy rod 2 brittle, peeled off, fallen off, and crushed, so that the titanium alloy rod 2 can be pickled more thoroughly and efficiently, thereby improving the pickling efficiency. Since the radii of the pickling rod 7, the driving roller 3, and the driven roller 4 are different, the bristles 8 on the pickling rod 7 will not touch the driving roller 3 and the driven roller 4 when repeatedly cleaning the titanium alloy rod 2, so that the pickling rod 7, the driving roller 3, the driven roller 4, and the bristles 8 will not affect each other's operation during operation, thus ensuring that the device can efficiently pickle the titanium alloy rod 2, and making the device not prone to failure. Since bearings are hermetically arranged at the joints of the rotating shaft I 5, the rotating shaft II 9, and the rotating shaft III 10 with the side wall of the pickling tank 1, the rotating shaft I 5, the rotating shaft II 9, and the rotating shaft III 10 maintain tightness while rotating, thereby preventing the pickling liquid from entering and damaging them, and further improving the overall safety of the device. A guide rail 13 is provided above the pickling tank 1; a telescopic rod 14 that can slide along the length direction of the guide rail 13 is vertically provided below the guide rail 13, and a gripper 15 for grasping the titanium alloy rod 2 is provided at the bottom of the telescopic rod 14. Since the pickling of the titanium alloy rod 2 is relatively dangerous and the pickling acid solution has a certain impact on the physical health of the staff, the titanium alloy rod 2 is fixed by the gripper 15 and placed on the driving roller 3 and the driven roller 4 for pickling. After the titanium alloy rod 2 is pickled, the gripper 15 is used again to fix the titanium alloy rod 2, and then the titanium alloy rod 2 is lifted by the telescopic rod 14, and then the pickled titanium alloy rod 2 is sent to the next cleaning process through the guide rail 13, so that only the machine needs to be operated by the staff during the entire production process of the titanium alloy rod 2, without directly contacting the titanium alloy rod 2, thereby improving the safety of the staff and ensuring the physical health of the staff.;

[0029] Embodiment 2

[0030] Based on Embodiment 1, the improvement is as follows: Please refer to Figure 3 - Figure 6As shown in the figure, a pickling device for titanium alloy bars includes a driving roller 3; a group of resistance-increasing grooves 16 are formed on the outer side wall of the driving roller 3; a cleaning block 17 is slidably connected to the outer side wall of the driving roller 3; the inner side wall of the cleaning block 17 is in mutual contact with the outer side wall of the driving roller 3; by providing a group of resistance-increasing grooves 16 on the outer side wall of the driving roller 3, the resistance when the driving roller 3 contacts the titanium alloy bar 2 is increased, so that it is easier to drive the titanium alloy bar 2 to rotate together when the driving roller 3 rotates. Thus, when the titanium alloy bar 2 is being cleaned, the cleaning efficiency and cleaning effect can be effectively improved. And after the cleaning of the titanium alloy bar 2 is completed, since the device is relatively complex and the resistance-increasing grooves 16 are relatively difficult to clean, when cleaning the resistance-increasing grooves 16, the cleaning block 17 can be moved back and forth, and the back-and-forth movement of the cleaning block 17 will clean the residual liquid and impurities in the resistance-increasing grooves 16, so that the device can effectively clean the resistance-increasing grooves 16 and the driving roller 3. And because a clamping groove 18 is formed on the outer side wall of the cleaning block 17; a hollow cylinder 19 is provided outside the cleaning block 17, and the hollow cylinder 19 is square-shaped, and the hollow cylinder 19 matches the clamping groove 18; limiting grooves 20 are formed on opposite sides of the inner wall of the clamping groove 18; a pair of limiting rods 21 are slidably connected to one side of the inner wall of the hollow cylinder 19; limiting blocks 22 are fixedly connected to the outer bottom ends of the pair of limiting rods 21, and the limiting blocks 22 match the limiting grooves 20; the top end of the outer wall of the limiting block 22 is in contact with the bottom end of the outer wall of the hollow cylinder 19; the pair of limiting blocks 22 are symmetric about the center line of the hollow cylinder 19; a double-threaded rod 23 is rotatably connected to one side of the inner wall of the hollow cylinder 19, and one end of the outer wall of the double-threaded rod 23 penetrates through the pair of limiting rods 21 and the outer side wall of the hollow cylinder 19, and the double-threaded rod 23 is threadedly connected to the pair of limiting rods 21. By placing the bottom end of the hollow cylinder 19 into the clamping groove 18 on the cleaning block 17 and then rotating the double-threaded rod 23, the rotation of the double-threaded rod 23 drives the pair of limiting rods 21 to move towards both sides at the same time, so that the pair of limiting rods 21 drive the pair of limiting blocks 22 to be clamped into the limiting grooves 20, so that the hollow cylinder 19 and the cleaning block 17 are fixed together, and then the hollow cylinder 19 is moved to drive the cleaning block 17 to move, so that the cleaning block 17 cleans the driving roller 3, so that the device can clean the driving roller 3 without directly contacting the cleaning block 17, making the work of the staff safer.

[0031] Working principle: By placing the titanium alloy bar 2 between the driving roller 3 and the driven roller 4, at this time, the motor 6 drives the rotation of the rotating shaft I 5, and the rotating shaft I 5 drives the rotation of the driving roller 3, so that the rotation of the driving roller 3 causes the titanium alloy bar 2 located on the driving roller 3 to rotate. And due to the rotation of the rotating shaft I 5, it will drive the rotation of the rotating shaft II 9 and the rotating shaft III 10, thereby driving the rotation of a pair of pickling rods 7 and the bristles 8 on the pickling rods 7, so that the bristles 8 wash the titanium alloy bar 2 during rotation, thus realizing the repeated cleaning of the titanium alloy bar 2. And one of the functions of the driving roller 3 and the driven roller 4 is to support the titanium alloy bar 2 to be cleaned, and the second function is to drive the titanium alloy bar 2 to rotate, thereby realizing the cleaning of different positions of the titanium alloy bar 2. Through the coordinated rotation of the titanium alloy bar 2 and the cleaning rod, the efficient cleaning of the titanium alloy bar 2 is realized, greatly improving the pickling efficiency and pickling effect of the pickling device for the titanium alloy bar 2. And because the radii of the pickling rod 7, the driving roller 3 and the driven roller 4 are different, the bristles 8 on the pickling rod 7 will not touch the driving roller 3 and the driven roller 4 when repeatedly cleaning the titanium alloy bar 2, so that the pickling rod 7, the driving roller 3, the driven roller 4 and the bristles 8 will not affect each other's operation during operation, thus ensuring that the device can efficiently pickle the titanium alloy bar 2, so that the device is not prone to failure. And the shock waves generated by the ultrasonic waves emitted by the ultrasonic vibration rod 11 during transmission make the dirt and impurities on the titanium alloy bar 2 brittle, peeled off, fallen off and crushed, so that the titanium alloy bar 2 can be pickled more thoroughly and efficiently, thus improving the pickling efficiency. And because the pickling of the titanium alloy bar 2 is relatively dangerous and the pickling liquid has a certain impact on the physical health of the staff, the titanium alloy bar 2 is fixed by the gripper 15 and placed on the driving roller 3 and the driven roller 4 for pickling. After the titanium alloy bar 2 is pickled, the titanium alloy bar 2 is fixed by the gripper 15 again, then the titanium alloy bar 2 is lifted by the telescopic rod 14, and then the pickled titanium alloy bar 2 is sent to the next cleaning process through the guide rail 13, so that only the machine needs to be operated by the staff during the whole production process of the titanium alloy bar 2, and there is no need to directly contact the titanium alloy bar 2, thus improving the safety of the staff and ensuring the physical health of the staff. And bearings are hermetically arranged at the joints of the rotating shaft I 5, the rotating shaft II 9, the rotating shaft III 10 and the side wall of the pickling tank 1, so that the rotating shaft I 5, the rotating shaft II 9 and the rotating shaft III 10 maintain tightness while rotating, thereby preventing the pickling liquid from entering and damaging them, so that the overall safety of the device is further improved. And a set of anti-slip grooves 16 are arranged on the outer side wall of the driving roller 3, so that the driving roller 3 increases the resistance when contacting the titanium alloy bar 2, so that the driving roller 3 is more likely to drive the titanium alloy bar 2 to rotate together when rotating, so that the cleaning efficiency and cleaning effect can be effectively improved when the titanium alloy bar 2 is being cleaned. And after the cleaning of the titanium alloy bar 2 is completed, because the device is relatively complex and the anti-slip grooves 16 are relatively difficult to clean,When cleaning the resistance-increasing groove 16, the cleaning block 17 can be moved back and forth, and the back-and-forth movement of the cleaning block 17 will clean the residual liquid and impurities in the resistance-increasing groove 16, so that the device can effectively clean the resistance-increasing groove 16 and the driving roller 3. And by putting the bottom end of the hollow cylinder 19 into the clamping groove 18 on the cleaning block 17 and then rotating the double-threaded rod 23, the rotation of the double-threaded rod 23 drives a pair of limiting rods 21 to move to both sides at the same time, so that the pair of limiting rods 21 drive a pair of limiting blocks 22 to be clamped into the limiting groove 20, so that the hollow cylinder 19 and the cleaning block 17 are fixed together. Then, moving the hollow cylinder 19 drives the cleaning block 17 to move, so that the cleaning block 17 cleans the driving roller 3, enabling the device to clean the driving roller 3 without directly contacting the cleaning block 17, thus making the staff safer during work.
