Description

Technical Field

[0001] The utility model relates to the technical field of die steel processing, in particular to a die steel processing and rust removal device. Background Art

[0002] Rust removal methods for mold steel processing mainly include chemical derusting, physical derusting, electrolytic derusting, dry ice cleaning, and heat treatment. Physical derusting uses mechanical equipment such as wire brushes, sandpaper, and grinding wheels to physically scrape and polish the mold steel surface. It is suitable for treating light rust. This method is environmentally friendly and pollution-free. Rinse thoroughly with clean water after polishing.

[0003] However, the physical rust removal methods in the existing technology have low efficiency in physical scraping and grinding of the mold steel surface due to problems with their working methods. For example, wire brushes, sandpaper, and grinding wheels are used to physically scrape and grind the mold steel surface. Even rust removal devices with a higher degree of mechanicality can only remove rust on one side of the mold steel, which still does not meet the high-efficiency processing requirements and affects the processing efficiency.

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] See also Figure 1-4 , a mold steel processing and rust removal device, comprising:

[0035] Base 1, base 1 is the base for assembling the device, two sets of conveyor belts 2 are set on the base 1 to convey the mold steel, the two sets of conveyor belts 2 are arranged at intervals along the same conveying direction, and the interval between the two sets of conveyor belts 2 does not affect the conveying of the mold steel;

[0036] An assembly cover 3 is fastened to the base 1 and spans over the two sets of conveyor belts 2;

[0037] The elastic contact grinding and rust removal rollers are two rollers of the same structure and are arranged on the base 1 inside the assembly cover 3. Among the two elastic contact grinding and rust removal rollers: the first elastic contact grinding and rust removal roller is fixedly arranged on the base 1 and is located between the two sets of conveyor belts 2 to grind the bottom surface of the mold steel conveyed and moved with the conveyor belts 2; the second elastic contact grinding and rust removal roller is located above the first elastic contact grinding and rust removal roller to grind the upper surface of the mold steel, that is, the two elastic contact grinding and rust removal rollers of the same structure, one upper and one lower, respectively, grind the upper and lower surfaces of the mold steel simultaneously, and the elastic surface of the elastic contact grinding and rust removal roller has sufficient friction with the surface of the mold steel to realize physical grinding and rust removal, thereby improving work efficiency;

[0038] a lifting and adjusting mechanism, which is provided on the top of the assembly cover 3 and is used to support the second elastic contact grinding and rust removal roller and adjust the height of the second elastic contact grinding and rust removal roller. Under the premise that the height of the first elastic contact grinding and rust removal roller is fixed and just grinding to the bottom of the mold steel, the second elastic contact grinding and rust removal roller is adjusted to support the second elastic contact grinding and rust removal roller so that it contacts the upper surface of the mold steel to perform grinding and rust removal; and

[0039] The dust removal mechanism is arranged on one side of the assembly cover 3 to absorb the dust and garbage generated by the elastic contact grinding and rust removal roller when grinding the mold steel to remove rust, so as to ensure the cleanliness of the processing position to avoid affecting the influence of debris on the rust removal of the mold steel.

[0040] Furthermore, both ends of the assembly cover 3 are open structures to allow the two sets of conveyor belts 2 and the mold steel to pass through.

[0041] Furthermore, the conveyor belt 2 has multiple first support rollers 4 that roll and support the conveyor belt and are located on the upper conveyor belt, so that the driving rollers at both ends of the conveyor belt 2 and the multiple first support rollers 4 serve as the main load-bearing structures for carrying the mold steel, and cooperate with the conveyor belt to drive the mold steel to be transported and moved.

[0042] Furthermore, a plurality of second support rollers 5 are provided on the upper surface of the base 1 at the end position of the conveying direction of the conveyor belt 2. The plurality of second support rollers 5 are arranged side by side. The mold steel conveyed by the conveyor belt 2 has been processed and rust-removed, and finally conveyed to the plurality of second support rollers 5 by the conveyor belt 2. The plurality of second support rollers 5 can smoothly receive the conveyed mold steel for unloading, waiting for the subsequent processed mold steel to be conveyed.

[0043] Furthermore, the elastic contact grinding and rust removal roller includes a horizontal shaft 6, an inner roller body 7 is sleeved and fixed on the horizontal shaft 6, an inner support ring 8 is sleeved and fixed on the outer side of the inner roller body 7, an outer support ring 9 is coaxially arranged on the outer side of the inner support ring 8, a plurality of elastic support sheets 10 are connected between the inner support ring 8 and the outer support ring 9, and the plurality of elastic support sheets 10 are evenly distributed in the circumferential direction, and a grinding layer 11 is sleeved and fixed on the outer side of the outer support ring 9;

[0044] It also includes a roller bracket 12, both ends of the roller bracket 12 are rotatably connected to both ends of the horizontal shaft 6 through bearings so that the horizontal shaft 6 can rotate axially. A driving motor 13 is set on one side of the roller bracket 12 to drive the horizontal shaft 6 to rotate.

[0045] Specifically, the roller bracket 12 rotates by supporting the horizontal shaft 6, which is then driven by the drive motor 13 to rotate the horizontal shaft 6. The inner roller body 7 on the horizontal shaft 6 drives the inner support ring 8, the outer support ring 9, and the elastic support sheet 10 to rotate, thereby rotating the grinding layer 11, so that the mold steel surface is polished and rust-removed by the rotating grinding layer 11. During this process, in order to ensure that the pressure of the grinding layer 11 on the mold steel surface can ensure polishing and rust removal, when the grinding layer 11 is pressed against the mold steel surface, the outer support ring 9 elastically deforms, and the elastic support sheet 10 of the force-bearing portion elastically deforms, which will exert a rebound force on the mold steel to ensure that polishing and rust removal are performed under sufficient pressure. The elastic deformation of the outer support ring 9 and the elastic deformation of the elastic support sheet 10 of the force-bearing part can also enable the elastic contact grinding and rust removal rollers at the upper and lower positions to be fixed in position. When the mold steel moves with the conveyor belt 2 and passes through the elastic contact grinding and rust removal rollers at the upper and lower positions, the elastic deformation of the elastic contact grinding and rust removal rollers at the upper and lower positions can give sufficient pressure to the upper and lower surfaces of the mold steel for effective grinding and rust removal.

[0046] Furthermore, the elastic support sheet 10 is connected between the inner support ring 8 and the outer support ring 9 in an S-shape. The curved structure of the elastic support sheet 10 with an S-shaped structure is conducive to elastic deformation to better provide rebound force.

[0047] Furthermore, the outer support ring 9 is an elastic plastic ring that can provide rebound force through deformation. Similarly, the elastic support sheet 10 can also be made of elastic plastic material. The polishing layer 11 also needs to use a deformable polishing material, such as a wire brush, sandpaper, etc., and its elastic recovery is provided by the outer support ring 9.

[0048] Furthermore, the lifting and adjusting mechanism includes two guide support rods 14 connected to the upper surface of the roller bracket 12 in the second elastic contact grinding and rust removal roller. The two guide support rods 14 are arranged parallel to each other. Two guide holes 15 are provided on the top surface of the assembly cover 3. The two guide holes 15 are arranged in a one-to-one correspondence with the two guide support rods 14 so that the guide support rods 14 pass through the corresponding guide holes 15 and slide in the guide holes 15. The top position between the two guide support rods 14 is connected to the first horizontal plate 16.

[0049] A second transverse plate 17 is provided above the first transverse plate 16. Both ends of the second transverse plate 17 are supported and fixed on the base 1 by legs 18. A threaded hole 19 is provided at the center of the second transverse plate 17. A threaded rod 20 is passed through the threaded hole 19 and threadedly engaged with the threaded rod 20. A rotating handle 21 is provided at the upper end of the threaded rod 20.

[0050] A limiting hole 22 is provided at the center of the first transverse plate 16 , and the lower end of the threaded rod 20 is arranged through the limiting hole 22 . Limiting plates 23 are provided on both sides of the lower end of the threaded rod 20 to prevent the threaded rod 20 from moving axially along the limiting hole 22 .

[0051] Specifically, the two guide support rods 14 move in the two guide holes 15, supporting the roller bracket 12 and the elastic contact grinding and rust removal roller to rise and fall, and play a guiding role. During the adjustment process, the handle 21 is manually rotated to drive the threaded rod 20 to rotate, and the threaded rod 20 is threadedly matched with the threaded hole 19 on the second cross plate 17. Under the premise that the second cross plate 17 is fixed on the base 1 by the support legs 18 and cannot move, the rotating threaded rod 20 is made to move axially at the same time, and then the threaded rod 20 drives the first cross plate 16 to rise and fall under the restriction of the limit plates 23 on the upper and lower sides of the limit hole 22, and then the roller bracket 12 and the elastic contact grinding and rust removal roller are driven to rise and fall through the two guide support rods 14 until the elastic contact grinding and rust removal roller is adjusted to be pressed against the upper surface of the mold steel.

[0052] Furthermore, the dust removal mechanism includes a plurality of dust collecting hoods 24 arranged on one side of the assembly hood 3 and a dust collector 25 arranged outside the assembly hood 3. The dust collecting hoods 24 and the dust collector 25 are connected through a dust collection pipe 26. The dust collector 25 performs dust collection and sucks away the dust and debris generated during the rust removal process through the dust collection pipe 26 and the plurality of dust collecting hoods 24 on one side of the assembly hood 3.

[0053] In summary, the device uses the elastic contact grinding and rust removal roller to simultaneously grind and remove rust from the upper and lower surfaces of the mold steel conveyed on the conveyor belt, thereby improving the processing efficiency of mold steel processing and rust removal.

[0054] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
