Description

Technical Field

[0001] The utility model belongs to the technical field of steel component processing, in particular to a grinding and rust removal device for steel component blanks. Background Art

[0002] Steel components refer to steel structure composite components that can bear and transfer loads and are made of steel plates, angle steels, channel steels, I-beams, welded or hot-rolled H-shaped steels that are cold-bent or welded and connected by connectors. The various components of steel components are also processed from blanks. Steel blanks are actually the steel billets that everyone is more familiar with. They are the original prototypes of steel in the steel production industry, or they can be said to be semi-finished products of steel building materials. General steel building materials, such as steel bars and steel plates, are made of steel billets that are heated and then rolled under strong pressure. After this process, the steel billets become the building materials we often see on construction sites. However, the steel component blanks need to be derusted before processing, but there are still the following disadvantages in the rust removal process:

[0003] First, the steel component blanks include plate-shaped, square-shaped, and cylindrical blanks. Before processing, the rust on the surface of the blanks usually needs to be removed, because the blanks will inevitably rust during long-term stacking. Only after rust removal can subsequent processing be convenient. However, the current rust removal device cannot remove the rust on all the plate-shaped, square-shaped, and cylindrical blanks.

[0004] Secondly, when it comes to rust removal of cylindrical blanks, the usual grinding and rust removal components are flat. For example, grinding with a grinding wheel machine is difficult to contact more areas around the cylindrical blank, resulting in a smaller area to be ground each time, which is time-consuming and laborious.

[0005] Finally, when grinding and rust removal of various types of blanks, the shapes of various types of blanks are different, which is not very convenient for stable transportation. Utility Model Content

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model is a grinding and rust removal device for steel component blanks, comprising a workbench, a roller assembly, a clamping plate, a cylinder, and a top plate.

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] See also Figure 1-7 As shown, the utility model is a grinding and rust removal device for steel component blanks, comprising a workbench 1, a roller assembly 2, a clamping plate 3, a cylinder 4, and a top plate 5. The upper surface of the workbench 1 is provided with a plurality of roller assemblies 2 distributed at equal intervals, and two symmetrically distributed clamping plates 3 are also provided above the roller assembly 2;

[0032] The workbench 1 is used as the main rust removal work and conveying carrier, and a large number of roller assemblies 2 are arranged on the top to assist in the conveying of the blanks. The workbench 1 and the roller assemblies 2 can be used in combination to adapt to the corresponding blank length. The clamping plate 3 is used to limit the blanks that need to be rust removed to prevent them from shifting during movement.

[0033] An inverted U-shaped frame 104 is fixed on the workbench 1, a cylinder 4 is fixed on the top of the frame 104, and the piston rod of the telescopic end of the cylinder 4 penetrates downward through the frame 104 and is fixed to a top plate 5, both sides of the top plate 5 are rotatably connected with brackets 501, the bracket 501 includes two strips 5011 and a roller 504, a connecting rod 5012 is fixed to the middle of the opposite surfaces of the two strips 5011, the roller 504 is rotatably connected between the opposite surfaces of the lower parts of the two strips 5011, and a grinding belt 505 is provided on the transmission sleeve between the two rollers 504; a collar 507 is sleeved on the outside of the connecting rod 5012 in each bracket 501, a threaded cylinder 508 is rotatably connected to the outer periphery of one collar 507, a threaded rod 509 is fixed to the outer periphery of the other collar 507, and the end of the threaded rod 509 away from the collar 507 is screwed into the threaded cylinder 508;

[0034] The frame 104 is used as a mounting carrier of the cylinder 4, so that the cylinder 4 and the top plate 5 are both located above the workbench 1 and the rolling assembly. Brackets 501 are arranged on both sides of the top plate 5. A roller 504 is rotated between two strips 5011 in the bracket 501. A grinding belt 505 is jointly driven and sleeved outside the two rollers 504. When the roller 504 rotates, the grinding belt 505 rotates, and the cylinder 4 controls the top plate 5 and its auxiliary components to move downward until the lower layer of the grinding belt 505 contacts the upper surface of the blank, and the grinding and rust removal process can be completed. According to actual needs, multiple groups of structures such as the grinding belt 505 and the top plate 5 can be arranged;

[0035] The distance between the two brackets 501 is adjustable. When the threaded barrel 508 is rotated, the threaded rod 509 will extend into or out of the threaded barrel 508. When the threaded rod 509 gradually enters the threaded barrel 508, the distance between the two brackets 501 decreases. At this time, the grinding belt 505 is no longer stretched straight, which is more beneficial for grinding cylindrical blanks (such as Figure 4 As shown in FIG. 5 ), the lower layer of the grinding belt 505 will contact the surface of the cylindrical blank more, so a larger area can be ground at one time, reducing time consumption.

[0036] The four corners of the bottom of the workbench 1 are all fixed with legs 102, and the two ends of the workbench 1 are fixed with symmetrically distributed ear plates 101, and an adjusting screw 103 is rotatably connected between the two ear plates 101 on the same end of the workbench 1;

[0037] Both ends of the clamping plate 3 are fixed with side plates 301, the lower part of the side plates 301 is located at the end of the workbench 1, the length of the clamping plate 3 is equal to the length of the workbench 1, and the adjusting screw 103 is provided with two opposite threads, each of which is threadedly connected to a side plate 301 at the end of the clamping plate 3;

[0038] The workbench 1 is supported on the ground by the legs 102, and its end is rotatably connected to the adjusting screw 103 through the ear plate 101. When the adjusting screw 103 rotates, the two side plates 301 will move closer to or farther from each other because of the two opposite threads on its outer circumference, so that the two clamping plates 3 can move closer to or farther from each other, thereby being suitable for clamping blanks of different widths.

[0039] The roller assembly 2 includes two base blocks 203 and a guide roller 201 rotatably connected between the two base blocks 203, and guide wheels 202 equidistantly distributed are fixed outside the guide roller 201; multiple roller assemblies 2 are used to assist in the transportation of the blank, and rolling transportation is more labor-saving. A large number of guide wheels 202 are arranged outside the guide roller 201 to contact the blank; the guide roller 201 can be connected to additional driving equipment.

[0040] A lifting slot 302 is provided in the clamping plate 3, and a lifting bar 303 is movably connected in the lifting slot 302. A lifting screw 304 is rotatably connected to the upper end of the lifting bar 303, and the upper thread of the lifting screw 304 penetrates and extends out of the upper part of the lifting slot 302.

[0041] The bottom of the lifting bar 303 is rotatably connected to a rotating wheel 305, and the top view area of ​​the rotating wheel 305 is larger than the top view area of ​​the lifting slot 302;

[0042] By rotating the lifting screw 304, the lifting bar 303 can be lifted up and down in the lifting groove 302, so that the rotating wheel 305 can be lifted and lowered to adapt to the center height of the blank. For example, for a cylindrical blank, the rotating wheel 305 can be moved to a position that is on the same horizontal line as its central axis to better assist in transportation. Part of the rotating wheel 305 extends out of the lifting groove 302, and the rotating wheel 305 is in contact with the blank, while the clamping plate 3 is not in contact.

[0043] Two ear plates 502 are symmetrically fixed at both ends of the top plate 5, and a rotating shaft 503 is rotatably connected between the two ear plates 502 at the same end of the top plate 5, and the upper parts of the two strip plates 5011 in the bracket 501 are fixed outside the rotating shaft 503, and a motor 506 is fixed on the side of any strip plate 5011 away from the roller 504, and the output shaft of the motor 506 is fixedly connected to the end of the roller 504 close to it;

[0044] The two strips 5011 in the bracket 501 can rotate around the shaft 503, and the motor 506 outside one strip 5011 rotates to drive the roller 504 connected to it to rotate. Under the linkage of the grinding belt 505, the other roller 504 is synchronously driven with the grinding belt 505, and the grinding belt 505 contacts the blank for grinding and rust removal.

[0045] The specific working principle of the utility model is as follows: first, the blank to be polished and rust-removed is placed on the roller assembly 2 on the workbench 1 for subsequent transportation, and the workbench 1 and the roller assembly 2 can be used in combination to adapt to the corresponding length of the blank, and then the lifting screw 304 is rotated to make the lifting bar 303 lift up and down in the lifting groove 302, so that the rotating wheel 305 is lifted and lowered to adapt to the center height of the blank. For example, for a cylindrical blank, the rotating wheel 305 can be moved to a position on the same horizontal line as the axis thereof, and then the adjusting screw 103 is rotated. Because there are two opposite threads on its periphery, the two side plates 301 will approach or move away from each other, that is, the two clamping plates 3 can be made to approach or move away from each other, so as to adapt to the clamping of blanks of different widths. At this time, the rotating wheel 305 is in contact with the blank, while the clamping plates 3 are not in contact;

[0046] Then the blank runs, and the motor 506 outside one strip plate 5011 rotates, driving the roller 504 connected thereto to rotate. Under the linkage of the grinding belt 505, the other roller 504 is synchronously driven with the grinding belt 505, and the cylinder controls the top plate 5 and its auxiliary components to move downward until the lower layer of the grinding belt 505 contacts the upper surface of the blank, and the grinding and rust removal process is completed;

[0047] The distance between the two brackets 501 is adjustable. When the threaded barrel 508 is rotated, the threaded rod 509 will extend into or out of the threaded barrel 508. When the threaded rod 509 gradually enters the threaded barrel 508, the distance between the two brackets 501 decreases. At this time, the grinding belt 505 is no longer stretched straight, which is more beneficial for grinding cylindrical blanks (such as Figure 4 As shown in FIG. 5 ), the lower layer of the grinding belt 505 will contact the surface of the cylindrical blank more, and a larger area can be ground at one time.

[0048] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
