Abstract

This invention discloses a peeling device for processing steel bars. The peeling device includes a feeding frame with a frame at the bottom, a grinding component, a receiving frame, and a rotary grinding mechanism. One end of the feeding frame is equipped with a pushing cylinder to horizontally push the steel bar out, while the other end of the feeding frame has a discharge hole for discharging the steel bar. The grinding component is located near the discharge hole, and the receiving frame receives the steel bar after grinding by the grinding component. The rotary grinding mechanism includes a driving component, a pre-cleaning component, and a rotating component. The driving component is located at the bottom of the feeding frame.

Description

Technical Field

[0001] This invention belongs to the field of steel bar processing technology, and specifically relates to a peeling device for steel bar processing. Background Technology

[0002] A steel bar peeling device is a mechanical device specifically designed to remove surface defects from steel bars. Its core function is to perform precision machining on the surface of steel bars through techniques such as turning, milling, or grinding to improve their dimensional accuracy, surface finish, and overall quality.

[0003] Currently, steel bar peeling devices primarily rely on cylinders to directly push the steel bar into the grinding zone. The steel bar initially comes into contact with the high-speed rotating grinding equipment from a stationary state, experiencing a significant acceleration process. During this acceleration period, the grinding effect is insufficient, resulting in uneven peeling in the front section of the steel bar, creating a processing blind spot. Simultaneously, the steel bar surface often has oxide scale debris and hard impurities from storage or transportation. These impurities directly enter the precision grinding zone with the steel bar, rapidly wearing down the grinding wheel or belt. This not only increases material costs but may also scratch the steel bar itself due to embedded impurities, affecting the final surface quality. The entire processing lacks adaptability to the incoming material condition, has a single function, and only performs a simple series of pushing and grinding operations, failing to optimize and protect the core grinding process beforehand. Summary of the Invention

[0004] The purpose of this invention is to provide a peeling device for steel bar processing, in order to solve the problems mentioned in the background art, such as poor peeling effect in the early stage of steel bar grinding and severe wear of the device due to impurities.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a peeling device for steel bar processing, the peeling device comprising a feeding frame with a frame at the bottom, a grinding component, a receiving frame, and a rotary grinding mechanism;

[0006] One end of the feeding frame is equipped with a pusher cylinder that pushes the steel bar out horizontally, while the other end of the feeding frame is provided with a discharge hole for the steel bar to be discharged.

[0007] The grinding component is located near the discharge hole, and the receiving frame receives the steel bar after grinding by the grinding component.

[0008] The rotary grinding mechanism includes a drive assembly, a pre-cleaning assembly, and a rotating assembly;

[0009] The drive component is located at the bottom of the feeding frame; one end of the drive component is connected to the pusher cylinder and rotates when the pusher cylinder reciprocates horizontally.

[0010] The rotating component is connected to the other end of the driving component;

[0011] The pre-cleaning component is disposed between the rotating component and the feeding frame, and the pre-cleaning component is connected to the driving component in a transmission manner;

[0012] The rotating component is tangent to the surface of the inner steel rod.

[0013] As a preferred technical solution of the present invention, the inside of the feeding frame is provided with a moving groove, which coincides with the extension and retraction path of the pushing cylinder on the vertical plane;

[0014] One end of the drive component passes through the moving groove and is connected to the output end of the pusher cylinder.

[0015] As a preferred technical solution of the present invention, the drive assembly comprises a fixed transmission part and a dynamic transmission part arranged coaxially.

[0016] The drive transmission unit includes a second drive shaft, a push plate, a cross plate, and a push column;

[0017] Both ends of the second drive shaft are radially limited within the frame at the bottom of the feeding frame by the shaft seat. A locking post is provided on the surface of the second drive shaft, and a spiral groove is fixed on the end face of the second drive shaft facing the fixed transmission part. A horizontal plate is fixed at the end of the frame at the bottom of the feeding frame. When the pushing cylinder retracts, it drives the end of the second drive shaft to contact the horizontal plate for limiting, thereby limiting the retraction position of the second drive shaft. At the same time, it can also separate from the first drive shaft and no longer drive the first drive shaft to rotate.

[0018] The top of the pusher plate is fixed to the output end of the pusher cylinder, while the bottom end extends through the discharge hole to the bottom of the discharge frame.

[0019] The horizontal plate is vertically fixed to the bottom end of the push plate, and the push column is fixed to the bottom end of the horizontal plate; the push column is inserted into the locking column.

[0020] As a preferred technical solution of the present invention, the fixed transmission part includes a drive shaft, a drive gear, and a drive disk;

[0021] The first drive shaft is also mounted in the frame at the bottom of the feeding frame via a shaft seat. An end hole for the spiral groove to engage is provided at the end of the first drive shaft. This end hole consists of a round hole and an internal hexagonal hole, where the round hole is the circumcircle of the internal hexagonal hole. The second drive shaft engages with the internal hexagonal hole of the end hole. When the pusher cylinder extends, it drives the pusher plate to move synchronously. At this time, the pusher plate drives the horizontal plate and the pusher column to move. The pusher column first pushes the second drive shaft horizontally and engages the spiral groove into the internal hexagonal hole of the end hole. This achieves the docking of drive shaft one and drive shaft two. When the push column moves again, it will move along the inside of the clamping column. Through the clamping of the push column, drive shaft two will rotate and drive drive shaft one to rotate synchronously. When the push cylinder retracts, the push column will first push drive shaft two away from drive shaft one in the direction of north, so that the clamping column moves into the round hole of the end hole. Then the push column returns along the clamping column and rotates drive shaft two in the opposite direction. At this time, the clamping column is in an idle state and will no longer drive drive shaft one to rotate.

[0022] The drive gear is fixed on the drive shaft, and the two rotate synchronously;

[0023] The drive disk is fixed to the end of the drive shaft, and the rotating component is sleeved on the outside of the drive disk and rotates at a low speed with the drive disk; wherein the drive shaft rotates synchronously with the drive disk, so when the pusher cylinder retracts to prepare for subsequent feeding, the drive shaft and drive disk no longer rotate.

[0024] At least two limiting rings are also fitted on the surface of the drive shaft one. The two limiting rings are symmetrically distributed on both sides of the shaft seat of the drive shaft one to ensure that the axial position of the drive shaft one remains unchanged and to avoid the change of its own position caused by the lateral movement of the drive shaft two.

[0025] As a preferred technical solution of the present invention, the rotating assembly includes a rubber wheel, a closing cover, and a stop ring;

[0026] The rubber wheel is placed between the feeding frame and the grinding assembly, and the rubber wheel is tangent to the surface of the steel side.

[0027] The closing cover is sleeved on the drive shaft and seals the rear surface of the rubber wheel;

[0028] The stop ring is installed inside the rubber wheel, and the two are arranged in a concentric circle. The inner wall of the stop ring has guide protrusions formed at equal angles, and the two side walls of the guide protrusions have an inwardly concave arc structure.

[0029] As a preferred technical solution of the present invention, the outer surface of the drive disk is provided with grooves at equal angles, and the opening of each groove extends vertically outward.

[0030] A steel ball is placed in the groove of the drive disc, and a spring is installed between the steel ball and the groove. The steel ball abuts against the side wall of the guide protrusion under the rebound of the second drive shaft. When the drive disc rotates with the first drive shaft, the steel ball is thrown outward by centrifugal force and the rebound of the spring, causing the steel ball to press against the side wall of the guide protrusion. This drives the stop ring and the rubber wheel to rotate. The rotation of the rubber wheel drives the steel rod that has not yet been ground and peeled to rotate. When the steel rod enters the grinding assembly for peeling, the steel rod is driven by the grinding assembly to rotate at high speed. At this time, the rubber wheel will also rotate at high speed along with the steel rod. The rotation speed of the rubber wheel and the stop ring will exceed that of the drive disc. When the two rotation speeds are different, the steel ball will move into the two guide protrusions and be pressed against the steel ball by the guide protrusions. The steel ball squeezes the spring. After the spring is compressed, the guide protrusion will push the steel ball over, thereby reducing the speed consumption when the rubber wheel drives the drive disc. When the pusher cylinder extends to its maximum value and is ready to retract, the steel rod completely enters the grinding assembly and no longer contacts the rubber wheel. At the same time, drive shaft one also separates from drive shaft two, and the whole assembly is in a stationary state.

[0031] As a preferred technical solution of the present invention, the pre-cleaning component includes a driven gear disc, a wire brush, and a mounting shaft;

[0032] The driven gear is positioned above the driving gear, and the two are meshed together.

[0033] The wire brush is fixed to the rear surface of the driven gear plate, and the mounting shaft passes through the driven gear plate and the wire brush, and is installed at the end of the feeding frame.

[0034] The bristles on the wire brush are in contact with the surface of the steel rod. When the drive gear rotates with the drive shaft, it will drive the driven gear plate and the wire brush to rotate, and the bristles on the wire brush will pre-scrape away impurities on the surface of the steel rod.

[0035] In a preferred embodiment of the present invention, the mounting shaft is positioned above the rubber wheel, and the two do not contact each other; the driven gear plate is in contact with the outer surface of the closing cover.

[0036] As a preferred technical solution of the present invention, both ends of the grinding component are equipped with feeding components. The feeding component has two guide wheels inside, and the two guide wheels are on the same plane as the grinding center of the grinding component. After the pushing cylinder pushes the steel rod out of the discharge hole, it will first pass through one of the feeding components, and then be ground by the grinding component. The ground steel rod will be transferred to the other feeding component, and finally transferred to the receiving frame. The feeding component has a driving component, such as a motor, to drive the guide wheels to rotate. The rotating guide wheels will move the steel rod toward the receiving frame.

[0037] As a preferred technical solution of the present invention, the interiors of both the feeding frame and the receiving frame are inclined. The plane where the pushing cylinder is located is the lowest point inside the feeding frame, while the receiving frame is inclined downward toward the rear surface of the grinding component. The inclination of the feeding frame is to allow the steel rod to roll down to the position of the pushing cylinder for easy ejection, while the inclination of the receiving frame is to allow the processed steel rod to be rolled and collected.

[0038] Compared with the prior art, the beneficial effects of the present invention are:

[0039] In this invention, the pushing action of the pusher cylinder, combined with the rotary grinding mechanism, imparts the required initial rotational speed to the steel bar, enabling it to reach a stable working speed the instant it enters the main grinding zone. This completely eliminates the processing blind spots caused by the acceleration process in traditional methods, ensuring uniform and consistent grinding results along the entire length of the steel bar. Furthermore, this invention utilizes the same power source to perform an active and effective pretreatment on the surface of the steel bar at the initial stage of rotation, removing firmly attached oxide scale and particulate impurities in advance. This creates a clean and ideal processing surface for the subsequent core grinding process, significantly improving the surface quality and consistency of the final product. At the same time, it greatly reduces the direct impact and wear of hard impurities on precision grinding tools, effectively extending the service life of key consumables such as grinding wheels and abrasive belts, and reducing the overall maintenance cost of long-term equipment operation. The entire processing flow is thus smoother and more efficient, and the equipment's adaptability and processing capacity to raw materials in different initial states are substantially enhanced.

[0062] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0063] Please see Figures 1 to 9 The present invention provides a technical solution: a peeling device for steel bar processing, the peeling device including a feeding frame 100 with a frame at the bottom, a grinding component 200, a receiving frame 300, and a rotary grinding mechanism.

[0064] One end of the feeding frame 100 is equipped with a pusher cylinder 101 that pushes the steel bar horizontally, while the other end of the feeding frame 100 is provided with a discharge hole 100a for the steel bar to be discharged.

[0065] The grinding component 200 is positioned near the discharge hole 100a, while the receiving frame 300 receives the steel bar after grinding by the grinding component 200.

[0066] The rotary grinding mechanism includes a drive assembly 400, a pre-cleaning assembly 500, and a rotating assembly;

[0067] The drive assembly 400 is located at the bottom of the feeding frame 100; one end of the drive assembly 400 is connected to the pusher cylinder 101 and rotates when the pusher cylinder 101 reciprocates horizontally.

[0068] The rotating component is connected to the other end of the drive component 400;

[0069] The pre-cleaning component 500 is disposed between the rotating component and the feeding frame 100, and the pre-cleaning component 500 is connected to the drive component 400 in a transmission manner;

[0070] The rotating component is tangent to the surface of the steel bar inside 101a.

[0071] In this embodiment, refer to Figure 8 The material feeding frame 100 has a moving groove 100b inside, which coincides with the extension and retraction path of the pusher cylinder 101 on the vertical plane.

[0072] One end of the drive component 400 passes through the moving groove 100b and is connected to the output end of the pusher cylinder 101.

[0073] In this embodiment, refer to Figure 6 , Figure 7 The drive assembly 400 comprises a fixed transmission part and a moving transmission part arranged coaxially.

[0074] The drive transmission unit includes a second drive shaft 406, a push plate 407, a cross plate 408, and a push column 409.

[0075] Both ends of the second drive shaft 406 are radially limited within the frame at the bottom of the feeding frame 100 by the shaft seat. A locking post 406a is provided on the surface of the second drive shaft 406, and a spiral groove 406b is fixed on the end face of the second drive shaft 406 facing the fixed transmission part. A horizontal plate 102 is fixed at the end of the frame at the bottom of the feeding frame 100. When the pushing cylinder 101 retracts, it drives the end of the second drive shaft 406 to contact the horizontal plate for limiting, thereby limiting the retraction position of the second drive shaft 406. At the same time, it can also be separated from the first drive shaft 401 and no longer drive the first drive shaft 401.

[0076] The top of the push plate 407 is fixed to the output end of the push cylinder 101, while the bottom end passes through the discharge hole 100a to the bottom of the discharge frame 100.

[0077] The horizontal plate 408 is vertically fixed at the bottom end of the push plate 407, while the push column 409 is fixed at the bottom end of the horizontal plate 408; the push column 409 is inserted into the locking column 406a.

[0078] In this embodiment, refer to Figure 4 , Figure 9 The fixed transmission unit includes a drive shaft 401, a drive gear 402, and a drive disc 403;

[0079] Drive shaft 401 is also mounted in the frame at the bottom of the feeding frame 100 via a bearing seat. An end hole 401a is provided at the end of drive shaft 401 for the spiral groove 406b to engage. This end hole 401a consists of a round hole and an internal hexagonal hole, where the round hole is the circumcircle of the internal hexagonal hole. Drive shaft 406 engages with the internal hexagonal hole of end hole 401a. When the pusher cylinder 101 extends, it drives the pusher plate 407 to move synchronously. At this time, the pusher plate 407 drives the horizontal plate 408 and the pusher column 409 to move. The pusher column 409 first pushes drive shaft 406 horizontally and engages the spiral groove 406b into the internal hexagonal hole of end hole 401a, thus achieving the docking of drive shaft 401 and drive shaft 406. When the pusher column 409 moves further, it will move along the inside of the engagement column 406a. The movement is achieved by the pusher 409 pressing against the drive shaft 406, which rotates the drive shaft 401 synchronously. When the pusher cylinder 101 retracts, the pusher 409 first pushes the drive shaft 406 away from the drive shaft 401, causing the locking pin 406a to move into the round hole of the end hole 401a. Then, the pusher 409 returns along the locking pin 406a and rotates the drive shaft 406 in the opposite direction. At this time, the locking pin 406a is in an idle state and will no longer drive the drive shaft 401 to rotate. The helical angle of the locking pin 406a should be an integer multiple of 360° to ensure that when the pusher 409 moves from one end of the locking pin 406a to the other end, the helical groove 406b maintains the same angle, which is convenient for subsequent insertion into the internal hexagonal hole of the end hole 401a.

[0080] The drive gear 402 is fixed on the drive shaft 401, and the two rotate synchronously;

[0081] The drive disk 403 is fixed to the end of the drive shaft 401, and the rotating component is sleeved on the outside of the drive disk 403 and rotates with the drive disk 403 at a low speed. The drive shaft 401 and the drive disk 403 rotate synchronously. Therefore, when the pusher cylinder 101 retracts to prepare for subsequent feeding, the drive shaft 401 and the drive disk 403 no longer rotate.

[0082] At least two limiting rings 410 are also fitted on the surface of the drive shaft 401. The two limiting rings 410 are symmetrically distributed on both sides of the shaft seat of the drive shaft 401 to ensure that the axial position of the drive shaft 401 remains unchanged and to prevent its position from changing due to the lateral movement of the drive shaft 406.

[0083] In this embodiment, refer to Figure 3 , Figure 4 , Figure 5 The rotating assembly includes a rubber wheel 601, a closing cover 602, and a stop ring 603;

[0084] The rubber wheel 601 is placed between the feeding frame 100 and the grinding assembly 200, and the rubber wheel 601 is tangent to the surface of the steel side.

[0085] The closing cover 602 is fitted onto the drive shaft 401 and seals the rear surface of the rubber wheel 601;

[0086] The stop ring 603 is installed inside the rubber wheel 601, and the two are arranged in a concentric circle. The inner wall of the stop ring 603 has a guide protrusion 603a formed at equal angles. The two side walls of the guide protrusion 603a have an inwardly concave arc structure.

[0087] In this embodiment, refer to Figure 5 The outer surface of the drive disk 403 has grooves at equal angles, and the opening of each groove extends vertically outward.

[0088] A steel ball 405 is installed in the groove of the drive disc 403, and a spring 404 is installed between the steel ball 405 and the groove. The steel ball 405 abuts against the side wall of the guide protrusion 603a under the rebound of the second drive shaft 406. When the drive disc 403 rotates with the first drive shaft 401, the steel ball 405 is thrown outward by centrifugal force and the rebound of the spring 404, and the steel ball 405 abuts against the side wall of the guide protrusion 603a, thereby driving the stop ring 603 and the rubber wheel 601 to rotate. Through the rotation of the rubber wheel 601, the steel rod that has not yet been ground and peeled is driven to rotate. When the steel rod enters the grinding component 200 for peeling, the steel rod is driven to rotate at high speed by the grinding component 200. At this time, the rubber wheel 603 rotates. 1 will also rotate at high speed with the steel rod. At this time, the rotation speed of the rubber wheel 601 and the stop ring 603 will exceed that of the drive disk 403. When the rotation speeds of the two are different, the steel ball 405 will move into the two guide protrusions 603a and be pressed against the steel ball 405 by the guide protrusions 603a. The steel ball 405 squeezes the spring 404. After the spring 404 is compressed, the guide protrusions 603a will pass the steel ball 405, thereby reducing the rotation speed consumption when the rubber wheel 601 drives the drive disk 403. When the push cylinder 101 extends to the maximum value and is ready to retract, the steel rod completely enters the grinding assembly 200 and no longer contacts the rubber wheel 601. At the same time, the drive shaft 1 401 is also separated from the drive shaft 2 406, and the whole is in a stationary state.

[0089] In this embodiment, refer to Figure 3 , Figure 4 The pre-cleaning assembly 500 includes a driven gear 501, a wire brush 502, and a mounting shaft 503;

[0090] The driven gear 501 is positioned above the driving gear 402, and the two are meshed together.

[0091] The wire brush 502 is fixed on the rear surface of the driven gear plate 501, and the mounting shaft 503 passes through the driven gear plate 501 and the wire brush 502, and is installed at the end of the feeding frame 100.

[0092] Among them, the bristles on the wire brush 502 are in contact with the surface of the steel bar. When the drive gear 402 rotates with the drive shaft 401, it will drive the driven gear 501 and the wire brush 502 to rotate, and the bristles on the wire brush 502 will pre-scrape away the impurities on the surface of the steel bar.

[0093] In this embodiment, the mounting shaft 503 is located above the rubber wheel 601, and the two do not contact each other; the driven gear 501 is in contact with the outer surface of the closing cover 602.

[0094] In this embodiment, refer to Figure 1 Both ends of the grinding assembly 200 are equipped with feeding assemblies 201. The feeding assembly 201 has two guide wheels inside, one upper and one lower. The two guide wheels are on the same plane as the grinding center of the grinding assembly 200. After the pushing cylinder 101 pushes the steel bar out of the discharge hole 100a, it will first pass through one of the feeding assemblies 201, and then be ground by the grinding assembly 200. The ground steel bar will be transferred to the other feeding assembly 201, and finally transferred to the receiving frame 300. The feeding assembly 201 has a driving component, such as a motor, on the outside to drive the guide wheels to rotate. The rotating guide wheels will move the steel bar toward the receiving frame 300.

[0095] In this embodiment, refer to Figure 1 The interiors of both the feeding frame 100 and the receiving frame 300 are inclined. The plane where the pushing cylinder 101 is located is the lowest point inside the feeding frame 100, while the receiving frame 300 is inclined downwards towards the rear surface of the grinding component 200. The inclination of the feeding frame 100 is to allow the steel bar to roll down to the position of the pushing cylinder 101 for easy ejection, while the inclination of the receiving frame 300 is to allow the processed steel bar to be rolled and collected.

[0096] The working principle of the peeling device is explained below:

[0097] First, the steel bar is placed in the feeding frame 100 and automatically rolls down to the plane where the pusher cylinder 101 is located. Then, the pusher cylinder 101 extends and pushes the steel bar out from the discharge hole 100a. At the same time, the pusher cylinder 101 drives the pusher plate 407 to move synchronously. The pusher plate 407 pushes the drive shaft 406 laterally through the horizontal plate 408 at the bottom and the pusher column 409, so that the spiral groove 406b is engaged in the end hole 401a, realizing the docking of the drive shaft 406 and the drive shaft 401. At this time, the pusher column 400a... 9. Moving along the locking post 406a forces the second drive shaft 406 to rotate, causing the first drive shaft 401 to rotate synchronously. When the first drive shaft 401 rotates, its driving gear 402 drives the driven gear disk 501 to rotate, thereby causing the bristles on the wire brush 502 to pre-scrape the surface of the steel bar and remove impurities. At the same time, the drive disk 403 at the end of the first drive shaft 401 rotates accordingly. Through the cooperation of the spring 404 and the steel ball 405 with the guide protrusion 603a of the stop ring 603, the steel ball 405 is pushed by centrifugal force. 05. The guide protrusion 603a is thrown out and pressed against the steel rod, thereby driving the stop ring 603 and the rubber wheel 601 to rotate. The rubber wheel 601 is tangential to the surface of the steel rod, giving the steel rod a stable initial rotational speed. The steel rod enters the grinding assembly 200 for high-speed grinding and peeling while rotating. At this time, the rubber wheel 601 no longer contacts the drive disk 403 and rotates. It is squeezed by the guide protrusion 603a and passes over the steel ball 405, so that it can rotate synchronously with the high-speed rotating steel rod in the grinding state. Then, after the steel rod is ground, it passes through the feeding assembly 20. 1. The material is guided and transported to the receiving frame 300 for collection. When the pushing cylinder 101 retracts, the push plate 407 drives the push column 409 to move in the opposite direction. First, the second drive shaft 406 is pushed away from the first drive shaft 401, so that the spiral groove 406b exits the end hole 401a. Then, the push column 409 returns along the locking column 406a. The second drive shaft 406 rotates freely and separates from the first drive shaft 401. The entire transmission system stops. The first drive shaft 401 and the drive disk 403 no longer rotate. The device returns to a static state and waits for the next pushing cycle.

[0098] Although embodiments of the invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
