Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe casting technology, specifically to a device for grinding and removing rust from the surface of stainless steel pipe castings. Background Technology

[0002] Stainless steel pipe castings refer to tubular parts or components manufactured using stainless steel as raw material through casting processes such as melting, pouring, and cooling. Afterwards, they undergo grinding and other subsequent processing. However, rust can occur during long-term storage. Before being put into use, a grinding and rust removal process is generally performed. A search revealed a patent with publication number CN221517316U that discloses a grinding and rust removal device for processing stainless steel pipe fittings. This device uses a moving component and a grinding component, along with an electric slide rail, to allow the moving component to simultaneously rotate and move the stainless steel pipe casting horizontally while grinding. This grinding method involves continuous, step-by-step grinding of the stainless steel pipe casting, resulting in low grinding efficiency. Therefore, a surface grinding and rust removal device for stainless steel pipe castings is designed to facilitate grinding and rust removal from the entire pipe casting at multiple angles, improving both grinding and rust removal efficiency and stability.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] Please see Figure 1-4 A stainless steel pipe casting surface grinding and rust removal device includes a base frame 1. An expansion support shaft 2 capable of rotation is placed horizontally on the top of the base frame 1. A grinding and rust removal arc block 4 capable of reciprocating left and right along the axis of the expansion support shaft 2 is arranged above the expansion support shaft 2. The device also includes a grinding and rust removal reciprocating movement structure for driving the grinding and rust removal arc block 4 to reciprocate. The grinding and rust removal reciprocating movement structure includes a left and right reciprocating rotation shaft rotatably connected above the expansion support shaft 2. The top of the grinding and rust removal arc block 4 is hinged to the left and right reciprocating rotation shaft through a guide elastic telescopic mechanism.

[0023] Specifically, it also includes a top frame 5 mounted above the expansion support shaft 2 and fixedly connected to the base frame 1. A reciprocating drive shaft is rotatably connected to the bottom of the top frame 5. It also includes a swing rotation drive mechanism that drives the reciprocating rotation shaft to swing left and right. The swing rotation drive mechanism includes a drive disk 15 rotatably connected to the top frame 5 via a grinding and rust removal drive motor 17. A guide slide frame 14 with racks 13 fixedly mounted on both sides of the bottom is horizontally slidably fitted in the middle of the top frame 5. The middle of the guide slide frame 14 is hinged to the eccentric part of the drive disk 15 via a connecting strip 16. Gears 12 that mesh with the racks 13 on both sides are fixedly mounted on both sides of the reciprocating rotation shaft. When the grinding and rust removal drive motor 17 is started, it is easy to drive the drive disk 15 to rotate. Through the cooperation of the connecting strip 16, it is easy to drive the guide slide frame 14 and the two racks 13 at the bottom to move left and right back and forth. Through the meshing of the racks 13 and the gears 12, the reciprocating rotation shaft is driven to swing left and right back and forth.

[0024] Specifically, the guiding elastic telescopic mechanism includes a sliding column 9 and a limiting sleeve 10 that mutually limit and guide sliding cooperation. An upper hinge seat 6 and a lower hinge seat 7 are fixedly installed on the top of the sliding column 9 and the bottom of the limiting sleeve 10, respectively. The upper hinge seat 6 is fixedly connected to a left-right reciprocating rotation axis, and a mounting bracket 8 is rotatably connected to the bottom of the lower hinge seat 7. The grinding and rust-removing arc block 4 is bolted to the mounting bracket 8. A compression spring 11 is fitted around the sliding column 9 and the limiting sleeve 10 as a whole. The two ends of the compression spring 11 are respectively connected to the upper hinge seat 6 and the lower hinge seat 7. The fixed connection, through the limiting guide sliding cooperation of the compression spring 11, the sliding column 9 and the limiting sliding sleeve 10, facilitates the extension and retraction of the grinding and rust removal arc block 4 when it moves laterally left and right, so that the grinding and rust removal arc block 4 always keeps close to the stainless steel pipe casting for grinding and rust removal. The setting of the lower hinge seat 7 and the upper hinge seat 6 makes it easy to keep the grinding and rust removal arc block 4 in a horizontal state. At the same time, the grinding and rust removal arc block 4 can be easily disassembled and replaced from the mounting bracket 8, which is convenient for grinding stainless steel pipe castings of different diameters.

[0025] Specifically, one end of the expansion support shaft 2 is equipped with a pipe rotation adjustment motor 3 that drives the expansion support shaft 2 to rotate. The pipe rotation adjustment motor 3 is fixedly installed on the top of the base frame 1 through a support plate. By starting the pipe rotation adjustment motor 3, the output shaft of the pipe rotation adjustment motor 3 rotates at a certain angle, thereby driving the expansion support shaft 2 to rotate synchronously at the same angle. Generally, grinding and rust removal operations are performed on the entire stainless steel pipe casting within other angle ranges.

[0026] Specifically, a shaft support mechanism adapted to the expansion support shaft 2 is provided on the side of the bottom of the expansion support shaft 2 away from the pipe rotation adjustment motor 3. The shaft support mechanism includes a support shaft support 18 and a lifting drive cylinder 19 fixedly installed on the base frame 1. The top output shaft of the lifting drive cylinder 19 is fixedly connected to the bottom of the support shaft support 18 through a guide sleeve 20. The bottom of the guide sleeve 20 is guided and slidably fitted with a guide column 21 fixedly connected to the base frame 1. The lifting drive cylinder 19 drives the guide sleeve 20 and the support shaft support 18 to move up and down, thereby facilitating the loading and unloading of the stainless steel pipe casting onto the expansion support shaft 2. The cooperation between the guide column 21 and the guide sleeve 20 improves the lifting stability of the support shaft support 18 and makes it easier to position the lifting drive cylinder 19 on one side of the expansion support shaft 2, reducing the adhesion of grinding debris to the lifting drive cylinder 19.

[0027] Specifically, it also includes a chip collection and moving box 22 placed below the expansion support shaft 2 and slidingly coordinated with the base frame 1. A handle 23 is provided on one side of the chip collection and moving box 22. The chip collection and moving box 22 facilitates the collection of grinding debris and allows the chip collection and moving box 22 to be pulled off the base frame 1 and moved by using the handle 23.

[0028] In use, lower the support shaft 18, then pull the grinding and rust-removing arc block 4 upwards. Next, place the stainless steel pipe casting onto the expansion support shaft 2, and then use the expansion support shaft 2 to support and fix the stainless steel pipe casting from the inside. Then release the grinding and rust-removing arc block 4, so that the grinding and rust-removing arc block 4 is tightly attached to the top of the stainless steel pipe casting from the top. Then start the left and right reciprocating rotating shaft to drive the guide elastic and the grinding and rust-removing arc block 4 to swing left and right. Through the setting of the guide elastic telescopic mechanism, the grinding and rust-removing arc block 4 is always kept close to the top of the stainless steel pipe casting for the entire left and right reciprocating grinding and rust removal operation. Then, by rotating the expansion support shaft 2, the entire stainless steel pipe casting is completely ground and rust-removed from multiple angles, which improves grinding efficiency and has high grinding stability.
