Description

Technical Field

[0001] This invention relates to the field of cold rolling roll production technology, specifically to an auxiliary clamping and turning device for the recycling and remanufacturing of forged steel cold rolling rolls. Background Technology

[0002] Cold rolling rolls are a type of roll that is smelted in a melting furnace, cast, and gradually forged. Cold rolling rolls include cold rolling work rolls, intermediate rolls, and support rolls. The work rolls are in direct contact with the workpiece, the intermediate rolls are in contact only with the work rolls, and the support rolls are in contact with the work rolls and may also be in contact with the intermediate rolls.

[0003] Chinese patent CN216807107U discloses a clamping and turning device for cold rolling roll forging production, which plays a supporting and stabilizing role in the processing of cold rolling rolls. At the same time, the motor starts to rotate the cold rolling roll, which can realize processing at different angles and avoid repeated loosening and tightening by the workers.

[0004] However, although the above-mentioned device can support and securely clamp the cold rolling roll, during the clamping process, it is necessary to continuously raise and lower the height of the cold rolling roll, then twist and adjust the distance between the two sets of support side plates, and finally rotate the screw to clamp the cold rolling roll. This series of adjustments can easily lengthen the installation process of the cold rolling roll. At the same time, after the forging of the forging is completed, the steps of unloading and unloading must be repeated, which forces the cold rolling roll processing steps to increase the workload invisibly, thereby reducing the forging efficiency of the cold rolling roll from the side.

[0005] To address this technical deficiency, a solution is proposed. Summary of the Invention

[0006] The purpose of this invention is to facilitate the simultaneous double-locking clamping of multiple sets of cold rolling rolls, shorten the multiple adjustment processes before cold rolling roll forging, and on this basis, not only can the cold rolling rolls be stably rotated to achieve full forging, but also the cold rolling rolls can be stably unloaded and unloaded, reducing disassembly and handling processes, and effectively improving the processing efficiency of cold rolling rolls.

[0007] The objective of this invention can be achieved through the following technical solution: an auxiliary clamping and flipping device for recycling and remanufacturing of forged steel cold rolling rolls, comprising a bottom frame, a limiting cylinder and a motor, wherein the bottom inner wall of the bottom frame is inclined at one end, and the limiting cylinder is rotatably connected to the middle section inside the bottom frame.

[0008] The motor is located at the center of the rear end of the bottom frame, and the output end of the motor extends into the bottom frame and is fixedly connected to the limiting cylinder. A cylinder is installed in the middle section of the limiting cylinder through the machine frame. A push frame with a concave structure is installed at one end of the cylinder through a push rod. Wedge-shaped blocks are fixedly installed on the front and rear inner walls of the push frame at the middle and one end. The two rows of wedge-shaped blocks are mirror symmetrical with respect to the central axis of the push frame.

[0009] The bottom inner wall of the base frame is provided with a mountain-shaped card frame at the center of the push frame, and the bottom inner wall of the mountain-shaped card frame is curved. The limiting cylinder has a sliding groove on one side at both the front and rear ends of the cylinder. Sliding strips are slidably connected inside both sets of sliding grooves, and one end of the sliding strip extends to the outside of the sliding groove and is fixedly connected to a clamping plate. Limiting mechanism one is provided in the middle section and on one side of the clamping plate. Vertical grooves are provided on the front and rear inner walls of the base frame near one end, and limiting mechanism two is provided between the two sets of vertical grooves.

[0010] Furthermore, the two rows of limiting mechanisms are mirror-symmetrical with respect to the central axis of the push frame. The inner end of the clamping plate near the slide bar is provided with an inner groove, and the side frame of the push frame is respectively fitted into the inner grooves of the two sets of inner grooves. The side of the two sets of clamping plates away from each other and the misalignment with the limiting mechanism are provided with conical blocks.

[0011] Furthermore, the limiting mechanism includes a cylinder, which is fixedly inserted inside the clamping plate, with the cylinder opening flush with the surface of the clamping plate. The end of the cylinder away from the opening extends to the outside of the clamping plate. Fixing frames are fixedly installed on the upper and lower ends and the inner walls on both sides away from the opening. An L-shaped abutment is fixedly inserted inside each set of fixing frames. One end of the abutment extends to the outside of the cylinder, and a sliding shaft is provided on one side of the abutment and at the end extending inside the cylinder.

[0012] Furthermore, an insert is fixedly installed at the center of the inner wall on the side of the cylinder away from the cylinder opening, and a T-shaped insert rod is connected through the cylinder opening. A spring damping shock absorber is fixedly connected to one end of the T-shaped insert rod and the corresponding insert. The end of the T-shaped insert rod away from the insert extends to the outside of the cylinder and is fixedly installed with a disc.

[0013] Furthermore, inclined sliding frames are fixedly installed on one side of the disc and at the upper and lower ends and both sides of the T-shaped insert rod. The four sets of sliding frames extend inclinedly from the center of the disc to the outer ring. Each set of sliding shafts is slidably connected to the interior of the corresponding sliding frame. A wedge-shaped abutment is fixedly installed on the other side of the disc.

[0014] Furthermore, the limiting mechanism two includes a connecting plate, which is slidably connected between two sets of vertical grooves. Each set of vertical grooves has a guide rod fixedly installed inside, and the front and rear ends of the connecting plate are respectively sleeved on the top of the guide rod. A spring coil is sleeved on the outside of the guide rod between the connecting plate and the inner wall of the bottom of the vertical groove.

[0015] Furthermore, rectangular blocks are fixedly installed at both ends of the bottom of the connecting plate, and a frame is inserted into the bottom of the rectangular blocks. The frame is fixedly installed on the inner wall of the bottom frame and corresponds to the rectangular blocks. A horizontal bar is horizontally installed inside the frame near the bottom.

[0016] Furthermore, a limiting groove is provided in the middle section of the crossbar, and the inner wall of one side of the limiting groove is inclined and corresponds to the rectangular block. One end of the crossbar extends to the outside of the frame and is horizontally hinged with a baffle plate. The other end of the crossbar also extends to the outer wall of the frame and is wound with a spring coil two. One end of the spring coil two is fixedly connected to the outer wall of the frame.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention uses a combination of a cylinder, a push frame, clamping plates, and a limiting mechanism. Two sets of cold rolling rolls are placed on the surface of a mountain-shaped clamping frame. The cylinder pushes the push frame and wedge-shaped blocks to move. The wedge-shaped blocks press against the side walls of the conical blocks, causing the two sets of clamping plates to move closer to each other. This forces the corresponding limiting mechanism to press against the end of the cold rolling roll. Then, the wedge-shaped blocks continue to move and press against the wedge-shaped cylinder. The wedge-shaped cylinder is pressed against and pushes the disc and several sliding frames. The relative movement of the sliding frames and the sliding shaft causes several sets of clamping plates to press against the outside of the cold rolling roll, thereby achieving double automatic clamping of the end of the cold rolling roll, reducing complex adjustment processes, and improving the processing efficiency of the cold rolling roll.

[0019] 2. This invention uses a combination of a motor, a limiting cylinder, and a limiting mechanism. After single-sided forging is completed, the motor drives the limiting cylinder, push frame, clamping plate, and the clamped cold rolling roll to rotate, facilitating the rotation of the cold rolling roll. Simultaneously, when the push frame rotates, it presses against the connecting plate, forcing the two sets of rectangular blocks to collide with the inner wall of the bottom of the frame, causing vibration. Consequently, the cold rolling roll also vibrates, accelerating the discharge of waste residue from its surface. At the same time, the push frame resets and moves, causing the cold rolling roll to unload. The push frame loses its pressure on the connecting plate, and the connecting plate and rectangular blocks reset upwards, losing their locking to the two sets of abutment plates. The cold rolling roll that falls off then slides downwards against the abutment plates, thus achieving stable unloading of the cold rolling roll. Attached Figure Description

[0029] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.

[0030] Example 1: Please refer to Figure 1 - Figure 7 As shown, an auxiliary clamping and flipping device for recycling cold rolling rolls of forged steel includes a base frame 1, a limiting cylinder 2 and a motor 3. The bottom inner wall of the base frame 1 is set at one end with an inclined surface, and the limiting cylinder 2 is rotatably connected to the middle section inside the base frame 1. The motor 3 is set at the center of the rear end of the base frame 1, and the output end of the motor 3 extends into the interior of the base frame 1 and is fixedly connected to the limiting cylinder 2.

[0031] A cylinder 4 is installed in the middle section of the limiting cylinder 2 through the machine frame. A push frame 5 with a concave structure is installed at one end of the cylinder 4 through the push rod. Wedge-shaped blocks 501 are fixedly installed on the front and rear inner walls of the push frame 5 at the middle and one end. The two rows of wedge-shaped blocks 501 are mirror symmetrical with respect to the central axis of the push frame 5. A mountain-shaped card frame 6 is installed on the bottom inner wall of the bottom frame 1 at the center of the push frame 5. The bottom inner wall of the mountain-shaped card frame 6 is curved.

[0032] The limiting cylinder 2 has a sliding groove 201 on one side at both the front and rear ends of the cylinder 4. The two sets of sliding grooves 201 are slidably connected to the sliding strip 202. One end of the sliding strip 202 extends to the outside of the sliding groove 201 and is fixedly connected to the clamping plate 7. The clamping plate 7 is provided with a limiting mechanism 8 in the middle section and on one side. The bottom frame 1 has a vertical groove 101 on the front and rear inner walls near one end. The two sets of vertical grooves 101 are provided together with a limiting mechanism 9.

[0033] The front and rear rows of limiting mechanisms 8 are mirror symmetrical with respect to the central axis of the push frame 5. The inner groove 701 is opened at the end of the clamping plate 7 near the slide bar 202, and the side frame of the push frame 5 is respectively fitted into the inner groove 701 of the front and rear rows. Conical blocks 702 are provided at the side of the two clamping plates 7 away from each other and at the misalignment of the limiting mechanism 8.

[0034] First, the two sets of cold rolling rolls are fed into the mountain-shaped clamping frame 6, and the middle section of the bottom surface of the cold rolling rolls is in contact with the bottom curved surface of the frame. The two sets of clamping plates 7 are located at the front and rear ends of the cold rolling rolls respectively. Then, the cylinder 4 is activated, which uses the push rod to push the push frame 5 to move. The push frame 5 and the two sets of clamping plates 7 move relative to each other from left to right. The wedge-shaped abutment block 501 moves to the adjacent conical abutment block 702, and the inclined surface of the wedge-shaped abutment block 501 continuously presses against the side inclined surface of the conical abutment block 702, forcing the conical abutment block 702 and the clamping plate 7 to move under pressure. Then, the slide bar 202 also moves along the inside of the slide groove 201. The two sets of clamping plates 7 move closer to each other. At the same time, the opposing limiting mechanisms 8 on the surfaces of the two sets of clamping plates 7 also press against the front and rear ends of the two sets of cold rolling rolls respectively, thereby realizing the centering positioning of the two sets of cold rolling rolls and the initial pressure at the ends.

[0035] Example 2: Please refer to Figure 2 , Figure 4 - Figure 5 As shown, the limiting mechanism 8 includes a cylinder 81, which is fixedly inserted inside the clamping plate 7. The opening of the cylinder 81 is flush with the surface of the clamping plate 7. The end of the cylinder 81 away from the opening extends to the outside of the clamping plate 7. Fixing frames 82 are fixedly installed on the upper and lower ends and the inner walls of both sides away from the opening. An L-shaped abutment plate 83 is fixedly inserted inside each set of fixing frames 82. One end of the abutment plate 83 extends to the outside of the cylinder 81, and a sliding shaft 84 is provided on one side of the abutment plate 83 and at the end extending inside the cylinder 81.

[0036] A tube 85 is fixedly installed at the center of the inner wall of the side of the cylinder 81 away from the opening, and a T-shaped rod 86 is connected through the opening of the tube 85. A spring damping shock absorber 87 is fixedly connected to one end of the T-shaped rod 86 and the corresponding tube 85. The end of the T-shaped rod 86 away from the tube 85 extends to the outside of the cylinder 81 and is fixedly installed with a disc 88. Inclined sliding frames 89 are fixedly installed on one side of the disc 88 and at the upper and lower ends and both sides of the T-shaped rod 86. Four sets of sliding frames 89 extend inclinedly from the center of the disc 88 to the outer ring. Each set of sliding shafts 84 is slidably connected to the inside of the corresponding sliding frame 89. A wedge-shaped abutment 810 is fixedly installed on the other side of the disc 88.

[0037] The two sets of limiting mechanisms 8, corresponding to the front and rear, move towards the end of the cold rolling roll at the same time. The ends of the two sets of cylinders 81 press against the ends of the cold rolling roll respectively. With the continuous pushing of the push frame 5, the wedge block 501 moves to the wedge cylinder 810. Similarly, the tip of the wedge block 501 continuously presses against the inclined surface of the wedge cylinder 810.

[0038] As a result, the wedge-shaped abutment 810 and the disc 88 move into the cylinder 81, and the T-shaped insert 86 presses against the spring damping shock absorber 87 to compress it. Meanwhile, the four sets of abutment plates 83 are simultaneously inserted into the cylinder 81 due to the traction at their ends. The four sets of abutment plates 83 extend outside the cylinder 81 and press against the outer wall of the cold rolling roll end, thereby achieving further clamping and restriction of the cold rolling roll end. This structure can simultaneously provide double restriction of the ends of multiple sets of cold rolling rolls to reduce the occurrence of forging detachment during the forging process.

[0039] Example 3: Please refer to Figure 1 , Figure 6 - Figure 7 As shown, the limiting mechanism 2 9 includes a connecting plate 91, which is slidably connected between two sets of vertical grooves 101. Each set of vertical grooves 101 has a guide rod 92 fixedly installed inside. The front and rear ends of the connecting plate 91 are respectively sleeved on the top positions of the guide rod 92. A spring coil 93 is sleeved on the outside of the guide rod 92 between the connecting plate 91 and the bottom inner wall of the vertical groove 101.

[0040] Rectangular blocks 94 are fixedly installed at both ends of the bottom of the connecting plate 91, and a frame 95 is inserted into the bottom of the rectangular blocks 94. The frame 95 is fixedly installed on the bottom inner wall of the bottom frame 1 and corresponds to the rectangular blocks 94. A horizontal bar 96 is horizontally arranged through the inside of the frame 95 near the bottom end. A limiting groove 97 is provided in the middle of the inside of the horizontal bar 96, and the inner wall of the limiting groove 97 is inclined and corresponds to the rectangular blocks 94. One end of the horizontal bar 96 extends to the outside of the frame 95 and is horizontally hinged to a baffle plate 98. The other end of the horizontal bar 96 also extends to the outer wall of the frame 95 and is wound with a spring coil 99. One end of the spring coil 99 is fixedly connected to the outer wall of the frame 95.

[0041] After the upper half of the cold rolling roll is processed, the motor 3 is started, which drives the limiting cylinder 2 to rotate 180 degrees. The clamping plate 7, the push frame 5 and the two sets of cold rolling rolls also rotate 180 degrees. The frame edge of the open end of the push frame 5 presses against the top surface of the connecting plate 91. The connecting plate 91 continues to sink and presses against the spring coil 93 to compress. The two sets of rectangular blocks 94 sink with the connecting plate 91 and insert into the vertical frame 95 until the bottom of the rectangular blocks 94 hits the bottom inner wall of the vertical frame 95. Because the push frame 5 is in contact with the connecting plate 91, the impact of the rectangular blocks 94 causes the connecting plate 91, the push frame 5 and the two sets of cold rolling rolls to vibrate to a certain extent, so as to help to remove the debris attached to the processed area of ​​the cold rolling roll more quickly.

[0042] At the same time, when the rectangular block 94 sinks downward, its bottom end first inserts into the corresponding limiting groove 97. The bottom end of the rectangular block 94 presses against the inclined inner wall of the limiting groove 97, forcing the end of the crossbar 96 with the baffle plate 98 hinged to be pulled into the vertical frame 95. The spring coil 2 99 is stretched, thereby locking the hinge end of the baffle plate 98, making it difficult to deflect arbitrarily, so as to prevent the cold rolling roll from falling off due to vibration and rolling out of the bottom frame 1.

[0043] As can be seen from Embodiments 2 and 3, as the connecting plate 91 sinks and the push frame 5 flips to a flat state, the two sets of cold rolling rolls can be processed. After the cold rolling rolls are also processed, the cylinder 4 is started again, which pulls the push frame 5 to reset and move. Multiple sets of wedge blocks 501 move synchronously. The wedge blocks 501 first disengage from the wedge cylinder 810, and under the rebound force of the spring damping shock absorber 87, the wedge cylinder 810, the disc 88 and multiple sets of sliding frames 89 are forced to reset and move to the outside of the cylinder 81. The sliding frames 89 move relative to the sliding shaft 84 again, causing multiple sets of abutments 83 to be pushed out of the cylinder 81 and lose their clamping on the ends of the cold rolling rolls, thereby assisting the two sets of cold rolling rolls to automatically fall off and unload.

[0044] As the push frame 5 moves linearly, its end gradually detaches from the top of the connecting plate 91. The connecting plate 91, having lost its pressure, resets under the rebound force of the spring coil 93. The two sets of rectangular blocks 94 rise synchronously with the connecting plate 91 and disengage from the limiting groove 97. The crossbar 96 resets under the rebound force of the spring coil 99. The end of the crossbar 96 hinged to the baffle plate 98 moves outward from the frame 95, and the baffle plate 98 loses its lock. As a result, the cold rolling roll falls off and slides down the inclined surface. The front and rear ends of the cold rolling roll press against the two sets of baffle plates 98 respectively. The deflection angle of the two sets of baffle plates 98 is adjusted according to the length of the cold rolling roll, and the opening and closing angle of the two sets of baffle plates 98 is adaptively changed according to the length of the cold rolling roll in order to achieve stable feeding of the cold rolling roll.

[0045] In use, the present invention firstly feeds two sets of cold rolling rolls into the mountain-shaped clamping frame 6, with the middle section of the bottom surface of the cold rolling rolls fitting against the curved bottom surface of the frame. The two sets of clamping plates 7 are located at the front and rear ends of the cold rolling rolls respectively. Then, the cylinder 4 is activated, which uses a push rod to push the push frame 5 to move. The push frame 5 and the two sets of clamping plates 7 move relative to each other from left to right. The wedge-shaped abutment block 501 moves towards the adjacent conical abutment block 702, and the inclined surface of the wedge-shaped abutment block 501 continuously presses against the side inclined surface of the conical abutment block 702, forcing the conical abutment block 702 and the clamping plate 7 to move under pressure. Then, the slide bar 202 also moves along the inside of the slide groove 201, and the two sets of clamping plates 7 move closer to each other. At the same time, the opposing limiting mechanisms 8 on the surfaces of the two sets of clamping plates 7 also press against the front and rear ends of the two sets of cold rolling rolls respectively, thereby achieving the centering positioning of the two sets of cold rolling rolls and the initial pressure at the ends.

[0046] Secondly, as the push frame 5 continues to push, the wedge-shaped abutment 501 moves to the wedge-shaped abutment cylinder 810. Similarly, the tip of the wedge-shaped abutment 501 continuously presses against the inclined surface of the wedge-shaped abutment cylinder 810. As a result, the wedge-shaped abutment cylinder 810 and the disc 88 move into the cylinder 81, and the T-shaped insert rod 86 presses against the spring damping shock absorber 87 to compress it. The four sets of abutment plates 83 are simultaneously inserted into the cylinder 81 due to the traction at their ends. The four sets of abutment plates 83 extend on the outer plate of the cylinder 81 and press against the outer wall of the end of the cold rolling roll, thereby achieving further clamping and limiting of the end of the cold rolling roll.

[0047] Next, after the upper half of the cold rolling roll is processed, the motor 3 is started, which drives the limiting cylinder 2 to rotate 180 degrees. The clamping plate 7, the push frame 5, and the two sets of cold rolling rolls also rotate 180 degrees. The frame edge of the open end of the push frame 5 presses against the top surface of the connecting plate 91. The connecting plate 91 continues to sink and presses against the spring coil 93 to compress. The two sets of rectangular blocks 94 sink with the connecting plate 91 and insert into the vertical frame 95 until the bottom of the rectangular blocks 94 hits the bottom inner wall of the vertical frame 95. Because the push frame 5 is in contact with the connecting plate 91, the impact of the rectangular blocks 94 causes the connecting plate 91, the push frame 5, and the two sets of cold rolling rolls to vibrate to a certain extent, so as to help to remove the debris attached to the processed area of ​​the cold rolling roll more quickly.

[0048] Finally, the two sets of cold rolling rolls that have been flipped can be processed. After the flipped surfaces of the cold rolling rolls have also been processed, the cylinder 4 is started again, and its traction push frame 5 is reset and moved. Multiple sets of wedge blocks 501 move synchronously. The wedge blocks 501 first disengage from the wedge cylinder 810, and under the rebound force of the spring damping shock absorber 87, the wedge cylinder 810, the disc 88 and multiple sets of sliding frames 89 are forced to reset and move towards the outside of the cylinder 81. The sliding frames 89 move relative to the sliding shaft 84 again, causing multiple sets of abutments 83 to be pushed out of the cylinder 81 and lose their clamping on the ends of the cold rolling rolls, thereby assisting the two sets of cold rolling rolls to automatically fall off and unload.
