Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of high-temperature alloy surface treatment, and in particular relates to a low-magnification corrosion treatment tool for preventing large-area contact and a use method thereof. Background Art
[0002] In the field of aero-engines, the quality of high-temperature alloys plays a key role in their subsequent processing and use. Macrostructure can be used as one of the important methods to test the quality of high-temperature alloys. It can often directly reflect the quality of the production process and products, and plays a decisive role in the quality of the products. However, traditional corrosion requires the disk-like parts to be placed in the loading frame as a whole, resulting in a large area of contact between the workpiece and the loading frame, poor corrosion effect, and need to be repaired, resulting in low production efficiency. Under extreme working conditions, it may even lead to no processing allowance for forgings and scrapping. Poor corrosion effect is an urgent problem to be solved in the low-magnification corrosion of disk-like parts. Summary of the invention
[0003] Purpose of the invention: To provide a low-magnification corrosion treatment tool and a method of use that can prevent large-area contact, so as to prevent disc-like parts from excessively contacting the loading frame during the low-magnification corrosion process, thereby causing poor corrosion effect.
[0004] Technical solution:
[0005] A low-magnification corrosion treatment tool for preventing large-area contact includes: a hanger 1, a mother frame 2, two hangers 3, a hanger rod 4, two hooks 5, and a hanger rod 6, wherein:
[0006] The suspension 1 is a plurality of square steels connected in the longitudinal, transverse and vertical directions to form a beam frame structure; the upper end of the suspension 1 is connected to a crane;
[0007] The trough body of the mother frame 2 is formed by connecting a number of square steels in the longitudinal, transverse and height directions. A connecting piece is provided at the upper end of the trough body. A slot formed by welding angle iron and steel plate is provided at the upper end of the connecting piece for assembly with the lower end of the suspension 1.
[0008] The front of the hook 3 is welded with steel plates to form a U-shaped groove, and the two ends of the back are welded into a flanging U-shaped groove for hanging with the mother frame 2 and the hanging rod 6;
[0009] The suspension rod 4 includes a rod and a steel bar, wherein two ends of the steel bar are respectively welded to two ends of the rod to form a triangular structure;
[0010] The upper end of the hook 5 is provided with a through hole for connecting with the two ends of the rod material of the suspension rod 4, and the lower end of the hook 5 is provided with a single-side opening structure for connecting with the two ends of the hanging rod 6;
[0011] The hanging rod 6 is a high temperature alloy rod-shaped structure.
[0012] Furthermore, the upper end slot of the connector in the mother frame 2 is a double slot, which is used to cooperate with the two limit columns at the lower end of the suspension 1 to prevent the workpiece from falling off due to shaking during the production transfer process.
[0013] Furthermore, the front U-shaped groove of the hook 3 is used to limit the position of the suspension rod.
[0014] Furthermore, the middle section of the hanging rod 6 is processed into a threaded state.
[0015] Furthermore, the thread diameter of the middle section of the hanging rod 6 is 0.5mm-2mm.
[0016] Furthermore, the gap between the upper U-shaped groove on the reverse side of the hook 3 and the mother frame 2 is 1-3 cm, which is convenient for sliding along the mother frame.
[0017] Furthermore, the thread pitch of the middle section of the hanging rod 6 is 2cm-3cm, and the gap between the two ends of the hanging rod 6 and the U-shaped groove at the lower end of the reverse side of the hook 3 is less than 0.5-1cm.
[0018] A method for using a low-magnification corrosion treatment tool to prevent large-area contact, comprising:
[0019] Step 1: Hang the hook 3 on the inner wall of the mother frame 2, and keep the hook parallel to the side wall of the mother frame to form a first component;
[0020] Step 2: The through holes of the suspension rod 4 and the hook 5 are connected, and the suspension rod 6 is passed through the inner hole of the disc-like component and then hung on the single-side opening structure of the hook 5 to form a second assembly, and the axial diameter direction of the forging is perpendicular to the suspension rod;
[0021] Step 3: Combine the first component and the second component so that both ends of the hanging rod 6 are located in the U-shaped groove and hung in the lower end U-shaped groove on the reverse side of the hook 3, hang the mother frame 2 on the hanger 1, and perform pickling.
[0022] Beneficial effects:
[0023] In the past, no measures were taken to avoid contact between disc-like parts. Forgings were placed freely in the loading frame, with a large contact area with the frame, less forging material, serious surface pollution after production, low production efficiency, high frequency of rework, and even serious corrosion and scrapping. Using the tooling of the present invention, the forgings are placed on the processed threaded hanging rods using a hanger before corrosion, and the side-standing hoisting increases the amount of loading. The inner circle of the forgings has only point contact with the threaded part of the hanging rod, which greatly reduces the contact area between the forgings and the loading frame, improves the low-multiple corrosion effect on the surface of the forgings, and improves production efficiency. The tooling is cleverly designed, simple to use, convenient to hoist, effectively utilizes the tank space, and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS
