Description

Technical Field

[0001] This utility model relates to a surface treatment device for steel processing, used for polishing the surface of steel, and belongs to the field of steel processing technology. Background Technology

[0002] Steel surface polishing mainly refers to surface treatment methods that reduce the roughness of steel surfaces through mechanical, chemical, or electrochemical methods to achieve a smooth or mirror-like finish. To improve polishing efficiency, existing technologies typically use fully automatic or semi-automatic polishing mechanisms to polish cylindrical steel raw materials, also known as round bars.

[0003] Existing polishing mechanisms typically include a frame with guide rollers rotatably mounted on it. A pusher roller assembly consisting of a row of rollers is rotatably mounted on one side of the guide rollers, with the rollers angled on the frame and their axes intersecting the axis of the guide rollers. A polishing wheel is rotatably mounted on the side of the frame where the pusher roller assembly is located. There is space between the guide rollers and the polishing wheel to accommodate the round steel to be polished. A base is fixedly mounted in each of the guide rollers, rollers, and polishing wheel, and a motor is mounted on each base. All the guide rollers, rollers, and polishing wheels are driven to rotate by the motors. While the rollers in the pusher roller assembly push the round steel forward along the guide rollers, the polishing wheel polishes the cylindrical surface of the round steel.

[0004] Using the above method, the round steel bars that have already been loaded can be polished while the subsequent round steel bars are being loaded. That is, loading and polishing are carried out simultaneously, saving polishing time and improving polishing efficiency.

[0005] However, when polishing round steel using the above method, it can usually only polish the cylindrical surface of the round steel, but not the end face, resulting in a poor polishing effect. Utility Model Content

[0006] The purpose of this utility model is to provide a surface treatment equipment for steel processing, so as to solve the problem that when polishing round steel with fully automatic or semi-automatic polishing machines in the prior art, only the cylindrical surface of the round steel can be polished, but the end face of the round steel cannot be polished, resulting in poor polishing effect.

[0007] To solve the above problems, the surface treatment equipment for steel processing involved in this utility model adopts the following technical solution: A surface treatment equipment for steel processing includes a cylindrical surface polishing section, the cylindrical surface polishing section includes a first frame, a guide roller is rotatably arranged on the first frame, a push roller assembly is rotatably arranged on one side of the guide roller, and a first polishing wheel is rotatably arranged on the first frame on the side where the push roller assembly is located; it also includes an end face polishing section arranged on one side of the cylindrical surface polishing section, the end face polishing section includes a second frame, a material discharge hole is opened on the second frame, and a first roller and a second roller are rotatably arranged side by side on the second frame at both ends of the material discharge hole, the first roller and the second roller... Two rollers are arranged parallel to the guide roller. The second roller is driven by a power mechanism to reciprocate horizontally on the second frame to move closer to or away from the first roller. Two second polishing wheels are symmetrically arranged on both sides of the material discharge hole on the second frame. The second polishing wheels are respectively located at the ends of the first roller and the second roller. The two second polishing wheels are driven by a power mechanism to reciprocate horizontally on the second frame to move closer to or away from each other. A guide part is fixedly arranged at one end of the material discharge hole below the second frame. The guide part has a receiving end and a discharging end. The receiving end of the guide part is located below the second frame, and the discharging end of the guide part extends above the guide roller.

[0008] A limit rod is fixedly extended upward on the first frame, and the gap of the limit rod is set in the gap of the push rollers in the push roller assembly.

[0009] A limiting component is fixedly installed on the second frame, and the limiting component extends above and at both ends of the first roller.

[0010] The second frame is equipped with a pressure roller for pressing down on the raw material to be polished during polishing. The pressure roller is slidably positioned above the first roller and the second roller.

[0011] The material guiding section is an inclined plate with the discharge end lower than the receiving end.

[0012] The material guide section is provided with guard plates on both sides.

[0013] The discharge end of the material guide is equipped with an openable and closable sealing door.

[0014] The guard plate is provided with a T-shaped sliding groove, and the sealing door is provided with a T-shaped sliding strip that cooperates with the T-shaped sliding groove. The sealing door is slidably mounted on the guard plate on both sides of the material guide section through the cooperation of the T-shaped sliding groove and the T-shaped sliding strip.

[0015] The sealing gate is driven to slide up and down by a linear drive mechanism. A fixed plate is provided on the material guide section directly above the sealing gate, and the linear drive mechanism is located between the sealing gate and the fixed plate.

[0016] The linear drive mechanism that drives the sealing door to slide up and down is a cylinder.

[0017] The first and second rollers of this invention can clamp the round steel to be polished between them. The two second polishing wheels can polish the two end faces of the round steel respectively. The guide part can convey the round steel with the end faces polished to the cylindrical surface polishing part below it. Then the first polishing wheel polishes the cylindrical surface of the round steel. All surfaces of the round steel can be polished at once, and the polishing effect is good.

[0018] The surface treatment equipment for steel processing of this utility model is equipped with a pusher roller group on the first frame. The pusher rollers in the pusher roller group can push the round steel forward along the guide roller while the first polishing wheel polishes the cylindrical surface of the round steel. In this way, it can make room for the next round steel that has been polished by the end face polishing part, so that the material guide part can convey the next round steel to the cylindrical surface polishing part. It can polish the end face of the next round steel while polishing the cylindrical surface of the previous round steel, shortening the polishing time and improving the polishing efficiency.

[0021] To make the technical objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model; that is, the described embodiments are only a part of the embodiments of this utility model, and not all of them. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] Specific embodiments of the surface treatment equipment for steel processing involved in this utility model are as follows: Figures 1-6The device includes a cylindrical polishing section 1 for polishing the cylindrical surface of round steel bars, where the round steel bars are the raw materials to be polished. The cylindrical polishing section 1 has a first frame 2, on which a guide roller 3 is rotatably mounted. A pusher roller assembly is rotatably mounted on one side of the guide roller 3. The pusher roller assembly consists of a set of pusher rollers 4, which are rollers whose axes intersect with the axis of the guide roller 3. The pusher rollers 4 can push the round steel bars on the cylindrical polishing section 1 to move forward along the guide roller 3. A first polishing wheel 5 is rotatably mounted on the first frame 2 on the side where the pusher roller assembly is located. The guide roller 3 and the first polishing wheel 5 are positioned between each other. The machine has a space to accommodate the round steel to be polished. When the round steel moves between the first polishing wheel 5 and the guide roller 3, the first polishing wheel 5 can polish the cylindrical surface of the round steel. It also has an end face polishing part 6 set on one side of the cylindrical surface polishing part 1. The end face polishing part 6 includes a second frame 7. The second frame 7 has a material drop hole 8. A first roller 9 and a second roller 10 are rotatably arranged side by side on both ends of the material drop hole 8 on the second frame 7. The first roller 9 and the second roller 10 are arranged parallel to the guide roller 3. A base 20 is fixedly installed on the second roller 10. Driven by a power mechanism, the machine base 20 moves horizontally reciprocating on the second frame 7 to approach or move away from the first roller 9. When the machine base 20 moves to the end close to the first roller 9, the first roller 9 and the second roller 10 can push the round steel to rotate between them. When the machine base 20 moves to the end away from the first roller 9, the round steel between the first roller 9 and the second roller 10 is released and falls from the discharge hole 8. Two second polishing wheels 11 are symmetrically arranged on both sides of the discharge hole 8 on the second frame 7. The second polishing wheels 11 are respectively located on the first roller 9 and the second roller 10. At both ends of shaft 10, two second polishing wheels 11 are driven by a power mechanism to reciprocate horizontally on the second frame 7 to move closer to or further away from each other. The horizontal reciprocating motion of the two second polishing wheels 11 to move closer to or further away from each other is the prior art. When the two second polishing wheels 11 move to the end that moves away from each other, space can be made for placing the round steel to be polished. When the two second polishing wheels 11 move to the end that moves closer to each other, the two second polishing wheels 11 polish the two end faces of the round steel rotating between the first roller 9 and the second roller 10 respectively.A guide section 12 is fixedly installed at one end of the discharge hole 8 below the second frame 7. The guide section 12 is used to convey the round steel polished by the end face polishing section 6 to the cylindrical surface polishing section 1. The guide section 12 also acts as a buffer to prevent the round steel polished by the end face polishing section 6 from falling onto the cylindrical surface polishing section 1 under its own weight. The guide section 12 is provided with a slag leakage hole (not shown in the figure), through which the waste slag polished by the end face polishing section 6 can fall. Below the guide section 12, which has a receiving end and a discharging end, the receiving end of the guide section 12 is located below the second frame 7. The discharging end of the guide section 12 extends above the guide roller 3 from the outside of the guide roller 3. After the round steel polished by the end face polishing section 6 falls from the dropping hole 8 to the receiving end of the guide section 12, the round steel moves along the guide section 12 towards the discharging end and falls from the discharging end towards the cylindrical surface polishing section 1. The so-called outside refers to the side away from the space containing the round steel to be polished.

[0023] In operation, firstly, drive the machine base 20, causing it to move the second roller 10 closer to the first roller 9, and simultaneously drive the two second polishing wheels 11 to move to opposite ends. Then, manually or using a separately equipped feeding mechanism, place the round steel to be polished onto the end-face polishing section 6, and drive the two second polishing wheels 11 to move closer to each other. The two second polishing wheels 11 then polish the two end faces of the round steel respectively. After end-face polishing is complete, drive the two second polishing wheels 11 to move to opposite ends, and simultaneously drive the machine base 20 to move the second roller 10 away from the first roller 9. The polished round steel is then released and falls from the discharge hole 8. This cycle can be repeated to continuously polish the end faces of different round steels. After being polished at the end face, the round steel bars, under their own gravity, fall from the drop hole 8 through the guide section 12 into the space of the cylindrical surface polishing section 1 that accommodates the round steel bars to be polished. The pusher 4 in the pusher wheel group pushes the round steel bars on the first frame 2 forward along the guide roller 3. During the forward movement of the round steel bars, on the one hand, the first polishing wheel 5 can polish the cylindrical surface of the round steel bars, and on the other hand, it can make room for the subsequent round steel bars to be polished, so that the guide section can transfer the next round steel bar to be polished to the cylindrical surface polishing section 1. By repeating this operation, different round steel bars can be polished continuously and comprehensively.

[0024] Specifically, a limiting rod 13 is fixedly extended upward on the first frame 2, and the gap of the limiting rod 13 is set in the gap of the push rollers in the push roller group. The limiting rod 13 is used to restrict the round steel between the guide roller 3 and the push roller group to prevent the round steel from falling off the outside of the push roller group.

[0025] Specifically, a limiting member 14 is fixedly installed on the second frame 7, with the limiting member 14 extending above and at both ends of the first roller 9. The limiting member 14 serves two purposes: firstly, it prevents the round steel from falling off the outside of the first roller 9; secondly, it restricts the two end faces of the round steel at the ends of the first roller 9 and the second roller 10, respectively.

[0026] Specifically, the second frame 7 is equipped with a pressure roller 15 for pressing the round steel to be polished during polishing. The pressure roller 15 is equipped with a pressure roller seat, and the pressure roller 15 is slidably positioned above the first roller 9 and the second roller 10 via the pressure roller seat.

[0027] Specifically, the guide section 12 is an inclined plate with the discharge end lower than the receiving end. In this way, without the need for additional power, the round steel can move from the receiving end to the discharge end on the guide section 12 under its own gravity.

[0028] Specifically, guard plates 16 are provided on both sides of the guide section 12. The guard plates 16 can prevent the round steel moving on the guide section 12 from falling off the sides of the guide section 12.

[0029] Specifically, an openable and closable sealing gate 17 is provided at the discharge end of the material guide section 12. Opening the sealing gate 17 allows the round steel to fall from the discharge end of the material guide section 12 towards the cylindrical surface polishing section 1; closing the sealing gate 17 confines the round steel to the discharge end of the material guide section 12. Closing the sealing gate 17 prevents the round steel from falling while restricting its position, ensuring that both ends of the round steel are on the same horizontal line, facilitating a smooth fall of the round steel towards the cylindrical surface polishing section 1 after the sealing gate 17 is subsequently opened.

[0030] Specifically, the guard plate 16 is provided with a T-shaped groove (not shown in the figure), and the sealing door 17 is provided with a T-shaped sliding strip (not shown in the figure) that cooperates with the T-shaped groove. The sealing door 17 is slidably mounted on the guard plates 16 on both sides of the guide section 12 through the cooperation of the T-shaped groove and the T-shaped sliding strip.

[0031] Specifically, the sealing door 17 is driven to slide up and down by a linear drive mechanism, and a fixing plate 18 is provided on the guide part 12 directly above the sealing door 17. The linear drive mechanism is located between the sealing door 17 and the fixing plate 18.

[0032] Specifically, the linear drive mechanism that drives the sealing door 17 to slide up and down is a cylinder 19. The cylinder body of the cylinder 19 is fixed on the fixed plate 18, and the piston rod of the cylinder 19 is fixed on the sealing door 17.

[0033] Specifically, the guide roller 3 is hollow, and a motor is installed inside the guide roller 3. The motor has a stator 21 and a rotor 22. The rotor 22 is fixed on the inner wall of the guide roller, that is, the guide roller 3 has a built-in motor. The guide roller 3 is driven to rotate by the built-in motor. The rotation mode of the guide roller 3 is the same as the rotation mode of the electric drum in the prior art.

[0034] In the above embodiments, the power mechanisms for driving the second roller to reciprocate horizontally on the second frame and the power mechanisms for driving the second polishing wheel to reciprocate horizontally on the second frame are both cylinders.

[0035] In the above embodiments, the way in which the drive roller, polishing roller, first roller and second roller rotate is the same as the way in which the drive guide roller rotates, and they are all driven by a built-in motor.

[0036] In the above embodiment, a limiting rod is fixedly extended upward on the first frame. This is an optimized technical solution. In other embodiments, the limiting rod may not be provided.

[0037] In the above embodiment, a limiting component is fixedly installed on the second frame, which is an optimized technical solution. In other embodiments, the limiting component may not be provided.

[0038] In the above embodiment, the second frame is provided with a pressure roller for pressing down on the round steel to be polished during polishing. This is an optimized technical solution. In other embodiments, the pressure roller may not be provided.

[0039] In the above embodiment, the guide section is an inclined plate with the discharge end lower than the receiving end, which is an optimized technical solution. In other embodiments, the guide section can also be horizontal, and a roller for conveying round steel is rotatably arranged on the guide section.

[0040] In the above embodiment, guard plates are provided on both sides of the material guide section. This is an optimized technical solution. In other embodiments, guard plates may not be provided.

[0041] In the above embodiment, an openable and closable sealing gate is provided at the discharge end of the material guide section. This is an optimized technical solution. In other embodiments, the sealing gate may not be provided.

[0042] In the above embodiment, the linear drive mechanism that drives the sealing door to slide up and down is a cylinder. In other embodiments, the cylinder can be replaced with a hydraulic cylinder.

[0043] The rollers, cylinders, and hydraulic cylinders in the above embodiments are all commercially available parts and belong to the prior art.
