Description

Technical Field

[0001] The invention relates to the technical field of square billet deburring, in particular to a square billet deburring machine and a control method. Background Art

[0002] After the billet is cut by the flame cutting machine, burrs will be generated on its lower surface. Most of the existing billet deburring machines use a single double-edged scraper to remove the burrs. Specifically, during the transportation of the billet, the scraper rises and uses the blade on one side to remove the burrs on the head of the billet, and uses the blade on the other side to remove the burrs on the tail of the billet. For example, the patent with the authorization announcement number CN212350642U discloses a deburring machine using the above method. However, the above deburring process requires the scraper to rise and support the lower surface of the billet, which requires a vertical upward force on the billet to make the scraper close to the lower surface of the billet to complete the deburring operation. However, if the lifting force of the scraper is too large, the billet will be lifted from the transport roller and the billet will be separated from the transport roller, affecting the transportation of the billet. If the lifting force of the scraper is adjusted to a small value, the burrs will not be completely removed.

[0003] In addition, the scraper used in the existing billet deburring machine is usually an integral scraper, the width of the scraper is slightly wider than the width of the billet cross section, but the cross section of the billet will shrink and deform during the casting process, and bulges or depressions are likely to occur on the lower surface of the billet, and the blade of the integral scraper is flat. In the process of removing burrs, when scraping burrs on the raised parts, burrs on both sides may remain, and when scraping burrs on the recessed parts, burrs in the middle part may remain, resulting in incomplete burr removal.

[0004] A combined billet deburring machine is disclosed in the patent with authorization announcement number CN202207840U. The device removes burrs by combining a rotating blade and a horizontal scraper, but the rotating blade and the horizontal blade are both mounted on a swinging frame. One end of the swinging frame is the support point of the swinging shaft, and the other end is supported by a lifting cylinder and the lifting cylinder controls the cutter head to be in tight contact with the billet. If the device is not well controlled, the billet may be lifted from the transport roller.

[0005] The patent with authorization announcement number CN214108721U discloses a mechanism for removing burrs from the ends of square billets with front and rear pressure rollers. The device uses two front and rear pressure roller assemblies to press the running square billet, so that it runs smoothly and ensures that the bottom of the square billet is in close contact with the cleaning roller. However, the device uses a cleaning roller to clean the burrs under the square billet. The cleaning roller part can only realize the lifting action and cannot cooperate with the movement to complete the deburring operation. In addition, when the lower surface of the above-mentioned square billet shrinks and deforms to produce bulges or depressions, it is still easy to cause the burrs to be not removed cleanly.

[0006] The patent with authorization announcement number CN105619201B discloses a square steel and square billet deburring device and a process method thereof. The device uses a first transverse spiral roller and a second transverse spiral roller to cooperate to complete the deburring operation of the square billet, but the structure of the device is not compact enough, the installation space occupied is large, and the action control is relatively complex. Summary of the invention

[0017] A control method of the billet deburring machine is specifically as follows: when the billet does not enter the frame, the first pressure roller, the second pressure roller and the third pressure roller in the pressure roller mechanism are all in a high position, the scraper mechanism is at the input side of the frame, and the scraper assembly is in a low position;

[0018] When the head end of the billet is transported into the frame through the conveying roller, the first pressing roller rotates downward to press the head end of the billet, the scraper assembly rises and abuts against the lower side of the head end of the billet, and then the scraper mechanism moves in the same direction as the conveying direction of the conveying roller so that the scraper assembly removes the burrs on the lower side of the head end of the billet, and the scraper mechanism moves to the output side of the frame, and then the scraper assembly descends to return to a low position, and the first pressing roller rotates upward to return to a high position;

[0019] The billet continues to be transported through the conveying roller until the tail end of the billet moves above the scraper mechanism on the output side of the frame. The second and third rollers in the roller mechanism turn down to press the billet, and the scraper assembly rises again to abut against the lower side of the tail end of the billet. The scraper mechanism then moves in the opposite direction of the conveying direction of the conveying roller to allow the scraper assembly to remove burrs on the lower side of the tail end of the billet, and the scraper mechanism returns to the input side of the frame. The scraper assembly then descends to return to a low position, and the second and third rollers turn up to return to a high position.

[0020] When the billet is transmitted in the frame through the transmission roller, the blocking arm is driven to rotate toward the output side of the frame. When the tail end of the billet is deburred, the tail end of the billet is blocked and limited by the blocking arm.

[0021] The advantages and positive effects of the present invention are:

[0022] 1. The present invention positions the square billet by a three-roller pressing mechanism, wherein when deburring is performed on the head end of the square billet, the first roller in the pressing mechanism is operated to press the square billet, and when deburring is performed on the tail end of the square billet, the second roller and the third roller in the pressing mechanism are operated to press the square billet, and considering that there is no equipment limit at the front of the billet after it is output, the third roller can press a position close to the middle of the billet, thereby cooperating with the second roller to ensure the flat state of the billet, thereby ensuring the deburring quality of the tail end of the billet.

[0023] 2. The pressing roller mechanism of the present invention is provided with a driving gear on the second hinge shaft at the connection between the second middle arm and the second swing arm, and a driven gear is provided on the third hinge shaft connecting the third swing arm and the upper end of the frame, and the driving gear drives the driven gear to rotate through the torque transmitted by the intermediate gear, so that the swinging of the second swing arm can also drive the swinging of the third swing arm, thereby achieving the purpose of using one driving device to drive the second pressing roller and the third pressing roller to move, which will not increase the number of driving devices of the entire equipment, thereby ensuring that the manufacturing cost of the equipment is controllable, and the present invention can also achieve the purpose of the second pressing roller first contacting the upper surface of the square billet for positioning, and then the third pressing roller contacting the upper surface of the square billet for flattening through the design of gear transmission ratio, the length of the second swing arm and the third swing arm.

[0024] 3. The scraper mechanism of the present invention is provided with a movable frame which can move horizontally left and right in the frame body, and the scraper assembly is driven to move by the movable frame to cooperate with the transmission of the square billet on the transmission roller to complete the deburring operation of the head end and the tail end of the square billet, which will not affect the transmission process of the square billet, and can realize the cyclic deburring operation of the head end and the tail end of each square billet, thereby improving the working efficiency. In addition, the movable frame, the transverse driving device and other components in the scraper mechanism of the present invention are all integrated in the frame body, so the overall structure of the present invention is compact and will not take up too much installation space.

[0025] 4. The lower end of the movable frame of the scraper mechanism of the present invention is provided with an L-shaped roller bracket, on which a roller is provided, and the roller is in a clamping cooperation form with the upper track and the lower track in the frame base, so that it can ensure that the movable frame moves smoothly and the scraper assembly can be lifted and lowered vertically and smoothly without deviation.

[0026] 5. The present invention provides a stop arm at the upper end of the frame, and the stop arm can only rotate toward the output side of the frame through the cooperation of the stop arm limit shaft and the stop block at the upper end. When the billet is transmitted, the stop arm will make adaptive rotation without affecting the transmission of the billet. When deburring the tail end of the billet, since the billet transmission direction is opposite to the moving direction of the scraper assembly, the scraper assembly may drive the billet (especially the small-sized and relatively light-weight billet) to retreat in the opposite direction and fail to complete the deburring operation smoothly. However, the present invention blocks the tail end of the billet from retreating by the stop arm contact at the lower end of the stop arm, thereby ensuring that the deburring operation at the tail end of the billet can be carried out smoothly.

[0027] 6. The present invention changes the single scraper in the prior art into a segmented structure including multiple single scrapers, and the width of each scraper is relatively small. In this way, when the present invention is working, each single scraper can automatically compress its own spring according to the protrusions and depressions on the lower surface of the square billet to achieve height adjustment to ensure that the burrs are removed cleanly.

[0028] 7. The present invention takes into account that the cross-section of the billet is small, and it is easy to deform in a red-hot state, and it may also deviate from the center during transportation. Therefore, the combined width of each single scraper in the scraper assembly of the present invention is greater than the width of the billet, wherein the combined width of all the single scrapers except the outermost single scrapers on both sides is close to the cross-sectional width of the billet and greater than the width of the billet, and when the billet deflects to the left or right, the outermost single scrapers on both sides will be used, so that the present invention can have the single scrapers working within the deformation range of the billet, thereby avoiding the situation where burrs are not scraped due to the narrow width of the tool.

[0049] like Fig.10 As shown, in this embodiment, the scraper assembly 301 includes a knife bar 3012, a spring 3015, a guide sleeve assembly and a lock nut 3016, wherein the scraper mounting seat 3018 is provided with a plurality of mounting holes, the knife bar 3012 is inserted into the corresponding mounting holes, and a guide sleeve assembly is provided between the outer wall of the knife bar 3012 and the inner wall of the mounting hole to ensure that the knife bar 3012 can smoothly slide vertically along the mounting hole, and the upper end of the knife bar 3012 is connected to the corresponding single scraper 3018 by bolts. 011 is fixedly connected, a spring 3015 is provided in the lower part of the guide sleeve assembly, and a spring upper limit surface 30122 is provided in the middle part of the knife bar 3012 to abut against the upper end of the spring 3015, a spring lower limit surface 3019 is provided in the lower end of the guide sleeve assembly to abut against the lower end of the spring 3015, a knife bar locking shaft 30121 is provided at the lower end of the knife bar 3012, and the knife bar locking shaft 30121 extends to the outside of the scraper mounting seat 3018 and is threadedly connected with the corresponding lock nut 3016.

[0050] like Fig.10 As shown, due to the reasons of continuous casting and roller conveying, the lower surface of the billet 5 is not flat.

The washer assembly 3017 can be in the form of a combination of suitable washers, gaskets, etc. according to actual needs, which is a well-known technology in the art.

[0053] The working principle of the present invention is:

[0054] like Figures 1 to 10 As shown, the present invention transmits the billet 5 into the frame 1 of the present invention through the transmission roller 6 and completes the deburring operation. The transmission roller 6 is a well-known technology in the art.

[0055] When the present invention works, Figure 1 As shown, when the square billet 5 has not yet entered the frame 1 of the present invention, the first pressing roller 204, the second pressing roller 208 and the third pressing roller 213 in the pressing roller mechanism 2 are all in a high position, the movable frame 302 in the scraper mechanism 3 is at the input side of the frame 1, and the scraper assembly 301 on the movable frame 302 is in a low position.

[0056] like Figure 2 As shown, when the billet 5 is driven into the frame 1 of the present invention through the transmission roller 6, the first roller driving device 201 in the roller mechanism 2 starts to drive the first intermediate arm 202 to rotate, and then drives the first swing arm 203 to rotate so that the first roller 204 turns downward to press the head end of the billet 5, and the scraper assembly 301 is driven to rise through the lifting drive device 305 on the movable frame 302 to abut against the lower side of the head end of the billet 5. The first roller 204 can ensure that the lower side of the billet 5 is in full contact with the scraper assembly 301. At this time, the second roller 208 and the third roller 213 in the roller mechanism 2 are still in a high position and will not affect the movement of the billet 5.

[0057] Then the transverse driving device 303 in the scraper mechanism 3 starts to drive the moving frame 302 to move to the left, thereby driving the scraper assembly 301 to move to the left to complete the deburring operation on the lower side of the head end of the billet 5. At this time, it is necessary to ensure that the moving speed of the scraper assembly 301 is faster than the transmission speed of the transmission roller 6, so that the billet on the lower surface of the head end of the billet 5 can be scraped off instantly by the scraper assembly 301. After completing the deburring operation on the head end of the billet 5, Figure 3 As shown, the scraper mechanism 3 also moves to the output side of the frame 1, and then the scraper assembly 301 descends to restore to a low position, and the first pressure roller 204 rotates upward to restore to a high position, and then Figure 4 As shown, the billet 5 continues to move to the left until the tail end of the billet 5 moves above the scraper mechanism 3 located on the output side of the frame 1 .

[0058] like Figure 4 As shown, when the tail end of the billet 5 moves to above the scraper mechanism 3 located on the output side of the frame 1, the second roller driving device 205 in the roller mechanism 2 is started. On the one hand, the second roller driving device 205 drives the second swing arm 207 to swing through the second intermediate arm 206 so that the second roller 208 is pressed on the upper surface of the tail end of the billet 5. On the other hand, when the second swing arm 207 rotates, the driving gear 209 on the second hinge shaft rotates, and the torque is transmitted through each intermediate gear 210 to drive the driven gear 211 on the third hinge shaft to rotate, so that the third hinge shaft drives the third swing arm 212 to swing and the third roller 213 is pressed on the upper surface of the billet 5. The reason for such a design is that when the billet 5 is input, since its rear part is still in the flame cutting machine and other equipment, it generally does not warp, and the billet 5 is output After that, there is no equipment in the front part. At this time, the tail end of the billet 5 is clamped by the second pressing roller 208 and the scraper assembly 301. The billet 5 may be tilted upward, which will affect the quality of burr removal. The present invention adds a third pressing roller 213, and the third swing arm 212 is longer than the second swing arm 207, which can make the third pressing roller 213 pressed at a position close to the middle of the billet 5. In this way, the present invention can ensure the flatness of the billet 5 during deburring through the joint action of the third pressing roller 213 and the second pressing roller 208, thereby ensuring the deburring quality. In addition, the present invention can achieve the purpose of the second pressing roller 208 first contacting the upper surface of the billet 5 for positioning, and then the third pressing roller 213 contacting the upper surface of the billet 5 for flattening through the design of the gear transmission ratio, the length of the second swing arm 207 and the third swing arm 212.

[0059] When the billet 5 is pressed by the second pressing roller 208 and the third pressing roller 213 and the scraper assembly 301 abuts against the lower surface of the tail end of the billet 5, the scraper assembly 301 quickly moves to the right to complete the deburring operation of the tail end of the billet 5, specifically: Figure 5As shown, when the billet 5 has not separated from the blocking arm 4, since the upper end of the blocking arm 4 is only provided with a block 405 on one side close to the output side of the frame 1, and the other side is not provided with a block 405, the blocking arm 4 will not affect the leftward movement of the billet 5, and it can be adaptively rotated with the transmission of the billet 5. When the billet 5 separates from the blocking arm 4, the blocking arm 4 will automatically return to the vertical position, and the blocking arm 4 cannot rotate to the other side because the upper end blocking arm limit shaft 406 is against the block 405 at the upper end of the frame 1. When the tail end of the billet 5 is positioned, the transverse driving device 303 in the scraper mechanism 3 is started again to drive the movable frame 302 to move right, and then drive the scraper assembly 301 to move quickly to the right. Since the moving direction of the movable frame 302 is opposite to the transmission direction of the transmission roller 6 and the moving speed is faster, some billets 5 with relatively small size specifications are easily driven by the scraper assembly 301 to retreat to the right, and as shown in FIG. Figure 6 As shown, since the blocking arm 4 cannot rotate, the blocking arm contact 401 at the lower end of the blocking arm 4 can block the square billet 5 from retreating, thereby ensuring that the scraper assembly 301 can complete the deburring operation on the lower surface of the tail end of the square billet 5.

[0060] like Figures 7-8 As shown, after the device of the present invention completes the deburring operation of the tail end of the billet 5, the scraper mechanism 3 also returns to the input side of the frame 1, and then the scraper assembly 301 descends and returns to the low position, and the second pressure roller 208 and the third pressure roller 213 also swing up and return to the high position. After the billet 5 is completely output, the next billet 5 can continue to be input into the frame 1 and repeat the above process, so that it can cooperate with the transmission roller 6 to realize automatic continuous cycle operation.
