Detailed Implementation
[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0024] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a pickling equipment for stainless steel seamless coils, comprising:
[0025] Pickling tank 1, wherein a drain pipe is installed on the pickling tank 1 and a valve is installed on the drain pipe. Opening the valve can drain the used pickling solution in the pickling tank 1 so as to clean the pickling tank 1 or inject new pickling solution.
[0026] The coil placement assembly includes a liftable mounting plate 4. Four support rods 2 are mounted on the pickling tank 1, and a support plate 3 is fixed to the upper end of each support rod 2. A hydraulic cylinder 5 is mounted on the support plate 3, and the output end of the hydraulic cylinder 5 is fixedly connected to the upper end of the mounting plate 4. When the hydraulic cylinder 5 operates, its output end moves up and down, thereby moving the mounting plate 4 up and down. Furthermore, a pressure supply device 7 is mounted on the support plate 3 and connected to the hydraulic cylinder 5 via a pipe. Hydraulic oil is supplied to the hydraulic cylinder 5 through the pressure supply device 7 to drive its operation. This is existing technology and will not be described in detail here.
[0027] To ensure stable up-and-down movement of the mounting plate 4, two through holes are provided on the support plate 3, and two guide rods 6 are fixed on the mounting plate 4. The guide rods 6 pass through the through holes and are slidably connected to them. Through the cooperation between the guide rods 6 and the through holes, the mounting plate 4 can be guided, thereby ensuring its stable movement.
[0028] Four steel cables 10 are fixed to the bottom of the mounting plate 4. The four steel cables 10 are arranged in a rectangle at the bottom of the mounting plate 4. Hooks 11 are fixed to the bottom of the four steel cables 10. Hanging rings 15 are hung on the four hooks 11. Fence-type placement frames 8 are fixed to the bottom of the four hanging rings 15. Connecting blocks are welded to the bottom of the hanging rings 15 and welded to the fence-type placement frames 8. This makes the hanging rings 15 more stably fixed to the fence-type placement frames 8.
[0029] The fence-type placement frame 8 is further explained as follows: The fence-type placement frame 8 includes two rectangular frames distributed vertically. The two rectangular frames, which are opposite each other, are fixedly connected by multiple tie rods. The connecting block is fixed on the upper rectangular frame, and the horizontal plate 12 is fixed on the lower rectangular frame, which can reduce the obstruction to the pickling solution.
[0030] Two rectangular tubes 9 are fixed at the bottom of the fence-type placement frame 8. The two rectangular tubes 9 are located at both ends of the bottom of the fence-type placement frame 8. The two rectangular tubes 9 are set to cooperate with the drive arm on the forklift. In this way, the coil placement component can be picked up and put down using the forklift. When a large number of coils are pickled, it is more convenient to transfer them using the forklift.
[0031] A horizontal plate 12 is fixed to the inner wall of the fence-type placement frame 8. Multiple conical blocks 13 are fixed on the horizontal plate 12. A limit rod 14 is fixed to the upper end of the conical block 13. The conical block 13 and the limit rod 14 are coaxially arranged. The coil is sleeved on the conical block 13 and the limit rod 14. The coil placement assembly drives the coil to move into the pickling tank 1 to pickle the coil.
[0032] Among them, multiple coil placement components can be produced. In actual use, the staff puts the coil on the outside of the conical block 13 and the limiting rod 14. The conical block 13 and the limiting rod 14 can limit the coil. Due to the setting of the limiting rod 14, the coil will not fall off even if it is tilted.
[0033] Then, a forklift is used to insert into the rectangular tube 9, and the coil placement assembly is moved to the pickling tank 1 and positioned at the four hooks 11. The worker hangs the hooks 11 on the hanging rings 15 and the forklift drives away. The hydraulic cylinder 5 drives the mounting plate 4, the fence-type placement frame 8, and the coil to move into the pickling tank 1. The pickling solution in the pickling tank 1 can pickle the coil. During the pickling process, the output end of the hydraulic cylinder 5 can move up and down. Since the coil is unstable on the conical block 13, the coil will shake, thereby changing the position between the coil and the conical block 13, which can pickle the coil more thoroughly and also make the coil and the pickling solution move relative to each other, improving the pickling effect of the coil.
[0034] Among them, for the coil that is not sealed at the top and bottom, since the coil is fitted on the conical block 13, the pickling solution can enter the coil and pickle the inside of the coil; after the pickling is completed, the output end of the hydraulic cylinder 5 is reset, so that the fence-type placement frame 8 leaves the pickling solution. Due to the placement method of the coil, the pickling solution inside the coil is also quickly discharged.
[0035] Then, the staff used a forklift to insert into the rectangular tube 9 to support it, removed the hook 11, moved the part to the cleaning pool for rinsing with clean water, and then suspended the prepared coil placement assembly for subsequent acid washing.
[0036] In summary, this novel utility model, with its multiple conical blocks 13 and limiting rods 14, can be used to support and limit the coil, avoiding the drawbacks of existing technologies in fixing the coil. It is applicable to coils of various inner diameters, can effectively flush the coil, can be used with forklifts, and can meet the needs of large-scale coil pickling operations in factories.
[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
