Description

Technical Field

[0001] The invention relates to the technical field of cold rolling roll production, in particular to an auxiliary clamping and turning device for recycling forged steel cold rolling rolls. Background Art

[0002] Cold rolling rolls are a type of rolls that are melted in a smelting 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 only in contact with the work rolls, and the support rolls are in contact with the work rolls and also with the intermediate rolls. Chinese patent CN216807107U discloses a clamping and flipping device for cold roll forging production, which plays a role in supporting and clamping the cold roll during the processing. At the same time, the motor is started to realize the rotation of the cold roll, so that processing at different angles can be realized, avoiding repeated loosening and clamping by the staff; However, although the above-mentioned device can realize the support and stable clamping of the cold rolling roller, during the clamping process, it is necessary to continuously raise and lower the height of the cold rolling roller, then adjust the spacing between the two sets of supporting side plates by twisting, and finally rotate the screw to clamp the cold rolling roller. This series of adjustments can easily lead to the lengthening of the installation process of the cold rolling roller. At the same time, after the forging is completed, the steps need to be repeated to unload the material, which invisibly increases the workload of the cold rolling roller processing steps and reduces the forging efficiency of the cold rolling roller from the side.

[0003] In view of the technical defects in this aspect, a solution is now proposed. Summary of the invention

[0007] Furthermore, the limiting mechanism includes a cylinder, which is fixed and passes through the inside of the splint, and the cylinder mouth is flush with the surface of the splint, and the end of the cylinder away from the cylinder mouth extends to the outside of the splint, and the upper and lower ends of the cylinder and the ends of the inner walls on both sides away from the cylinder mouth are fixedly installed with fixed frames, and each group of the fixed frames is fixed with an L-shaped support plate, one end of the support plate extends to the outside of the cylinder, and a sliding shaft is provided on one side of the support plate and extends to one end inside the cylinder.

[0008] Furthermore, an insert cylinder is fixedly installed at the center of the inner wall on one side of the cylinder away from the cylinder mouth, and a T-shaped insert rod is connected through the cylinder mouth, a spring damping shock absorber is fixedly connected between one end of the T-shaped insert rod and the corresponding insert cylinder, and the end of the T-shaped insert rod away from the insert cylinder extends to the outside of the cylinder and is fixedly installed with a disc.

[0009] 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 insertion rod. Four groups of sliding frames extend obliquely from the center of the disc to the outer circle. Each group of sliding shafts is slidably connected to the inside of the corresponding sliding frame. A wedge-shaped resistance cylinder is fixedly installed on the other side of the disc.

[0010] Furthermore, the second limiting mechanism includes a connecting plate, and the connecting plate is slidably connected between the two groups of vertical grooves. A guide rod is fixedly installed inside each group of vertical grooves, and the front and rear ends of the connecting plate are respectively sleeved on the top position of the outside of the guide rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is to arrange a cylinder, a push frame, a clamping plate and a limiting mechanism to cooperate with each other, and two groups of cold rolling rollers are respectively placed on the surface of the mountain-shaped clamping frame. The cylinder pushes the push frame and the wedge-shaped block to move, and the wedge-shaped block presses the side wall of the conical block respectively to make the two groups of clamping plates close to each other, and forces the corresponding limiting mechanism to press against the end of the cold rolling roller. Then, the wedge-shaped block continues to move to press the wedge-shaped cylinder, and the wedge-shaped cylinder is pressed to push the disc and a plurality of sliding frames, and the sliding frame and the sliding shaft move relative to each other so that a plurality of groups of plates are pressed against the outside of the cold rolling roller, thereby realizing double automatic clamping of the end of the cold rolling roller, reducing complex adjustment procedures, and improving the processing efficiency of the cold rolling roller; 2. The present invention cooperates with a motor, a limit cylinder and a limit mechanism. When the single-sided forging process is completed, the motor drives the limit long cylinder, the push frame, the clamping plate and the clamped cold rolling roller to flip over, so as to facilitate the flipping process of the cold rolling roller. At the same time, when the push frame flips, the connecting plate is pressed to force the two groups of rectangular blocks to collide with the inner wall of the bottom of the frame and vibrate. Therefore, the cold rolling roller also vibrates and accelerates the discharge of waste slag on its surface. At the same time, the push frame resets and moves to cause the cold rolling roller to unload, and the push frame loses the pressure on the connecting plate. The connecting plate and the rectangular block reset upward and lose the locking of the two groups of abutment plates. The cold rolling roller that falls off presses the abutment plate and slides downward, thereby realizing stable unloading of the cold rolling roller. BRIEF DESCRIPTION OF THE DRAWINGS

A cylinder 4 is provided at the middle section of the limit long cylinder 2 through the machine frame, and a push frame 5 with a concave structure is provided at one end of the cylinder 4 through a push rod, and wedge-shaped abutments 501 are fixedly installed at the middle end and one end of the front and rear inner walls of the push frame 5, and the two rows of wedge-shaped abutments 501 are mirror-symmetrical with respect to the central axis of the push frame 5, and a mountain-shaped clamping frame 6 is provided at the inner wall of the bottom of the bottom frame 1 at the center of the push frame 5, and the inner wall at the bottom of the mountain-shaped clamping frame 6 is arranged in a curved surface; One side of the limiting long tube 2 is provided with a slide groove 201 at the front and rear ends of the cylinder 4, and the two sets of slide grooves 201 are slidably connected with a slide bar 202, and one end of the slide bar 202 extends to the outside of the slide groove 201 and is fixedly connected with a clamping plate 7, and a limiting mechanism 8 is provided at the middle section and one side of the clamping plate 7, and a vertical groove 101 is provided near one end of the front and rear inner walls of the bottom frame 1, and a limiting mechanism 9 is provided between the front and rear sets of vertical grooves 101; The front and rear rows of limit mechanisms 8 are mirror-symmetrical with respect to the central axis of the push frame 5. An inner groove 701 is provided at one end of the clamping plate 7 close to the slide bar 202, and the side frames of the push frame 5 are respectively sleeved in the front and rear two groups of inner grooves 701. Conical stop blocks 702 are provided at the side faces of the two groups of clamping plates 7 away from each other and at the offset positions with the limit mechanisms 8. First, the two groups of cold rolling rollers are respectively unloaded to the mountain-shaped clamping frame 6, and the middle section of the bottom surface of the cold rolling rollers is fitted with the bottom curved surface of the frame, and the two groups of clamping plates 7 are respectively located at the front and rear ends of the cold rolling rollers, and then the cylinder 4 is started, which uses the push rod to push the push frame 5 to move, and the push frame 5 and the two groups of clamping plates 7 move left and right relative to each other, and the wedge-shaped stop block 501 moves toward the adjacent conical stop block 702, and the inclined surface of the wedge-shaped stop block 501 continuously presses the side inclined surface of the conical stop block 702, forcing the conical stop block 702 and the clamping plate 7 to move, then the slide bar 202 also moves along the inside of the slide groove 201, and the two groups of clamping plates 7 approach each other. At the same time, the limiting mechanisms 8 on the surfaces of the two groups of clamping plates 7 also press against the front and rear ends of the two groups of cold rolling rollers, thereby realizing the centering positioning of the two groups of cold rolling rollers and the preliminary pressing of the ends.

[0019] Example 2: Please refer to Figure 2 , Figure 4 - Figure 5 As shown, the limiting mechanism 8 includes a cylinder 81, which is fixed and passes through the inside of the clamping plate 7, and the cylinder mouth of the cylinder 81 is flush with the surface of the clamping plate 7, and the end of the cylinder 81 away from the cylinder mouth extends to the outside of the clamping plate 7, and the upper and lower ends of the cylinder 81 and the ends of the inner walls on both sides away from the cylinder mouth are fixedly installed with fixed frames 82, and each set of fixed frames 82 is fixedly penetrated by an L-shaped abutment plate 83, and 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 extends to one end inside the cylinder 81; An insert tube 85 is fixedly installed at the center of the inner wall of the cylinder 81 away from the cylinder mouth, and a T-shaped insert rod 86 is connected to the cylinder mouth of the insert tube 85, and a spring damping shock absorber 87 is fixedly connected between one end of the T-shaped insert rod 86 and the corresponding insert tube 85, and the end of the T-shaped insert rod 86 away from the insert tube 85 extends to the outside of the cylinder 81 and is fixedly installed with a disk 88, and one side of the disk 88 and the upper and lower ends and both sides of the T-shaped insert rod 86 are fixedly installed with inclined sliding frames 89, four groups of sliding frames 89 extend obliquely from the center of the disk 88 to the outer circle, and each group of sliding shafts 84 are slidably connected to the inside of the corresponding sliding frame 89, and a wedge-shaped anti-tube 810 is fixedly installed on the other side of the disk 88; The two sets of limit mechanisms 8 corresponding to the front and rear simultaneously approach the ends of the cold rolling roller, and the ends of the two sets of cylinders 81 are pressed against the two ends of the cold rolling roller respectively. Then, with the continuous pushing of the push frame 5, the wedge-shaped stop block 501 moves to the wedge-shaped stop cylinder 810. Similarly, the tip of the wedge-shaped stop block 501 continuously presses against the inclined surface of the wedge-shaped stop cylinder 810. As a result, the wedge-shaped abutment cylinder 810 and the disc 88 move toward the inside of the cylinder 81, and the T-shaped insert rod 86 presses the spring damping shock absorber 87 to cause compression, and the four groups of abutment plates 83 are pulled at the ends and inserted into the inside of the cylinder 81 at the same time. The four groups of abutment plates 83 extend on the outer plate body of the cylinder 81 and press against the outer wall of the end of the cold rolling roller respectively, thereby further clamping and limiting the end of the cold rolling roller. This structure can perform double limitation on the ends of multiple groups of cold rolling rollers at the same time to reduce the possibility of forgings falling off during forging.

[0020] Example 3: Please refer to Figure 1 , Figure 6 - Figure 7 As shown, the second limiting mechanism 9 includes a connecting plate 91, and the connecting plate 91 is slidably connected between the two groups of vertical grooves 101, and a guide rod 92 is fixedly installed inside each group of vertical grooves 101, and the front and rear ends of the connecting plate 91 are respectively sleeved on the top position of the outside of the guide rod 92, and the outside of the guide rod 92 is located between the connecting plate 91 and the bottom inner wall of the vertical groove 101 and is sleeved with a spring group coil 93; A rectangular block 94 is fixedly installed near both ends of the bottom of the connecting plate 91, and a frame 95 is inserted at the bottom of the rectangular block 94. The frame 95 is fixedly installed on the inner wall of the bottom of the bottom frame 1 and corresponds to the rectangular block 94. A cross bar 96 is horizontally penetrated near the bottom end of the frame 95. A limiting groove 97 is arranged in the middle of the cross bar 96, and the inner wall of one side of the limiting groove 97 is inclined and corresponds to the rectangular block 94. One end of the cross bar 96 extends to the outside of the frame 95 and is laterally hinged with a blocking plate 98. The other end of the cross bar 96 also extends to the outer wall of the frame 95 and is wound with a spring coil 99, and one end of the spring coil 99 is fixedly connected to the outer wall of the frame 95. After the processing of the upper half of the cold rolling roller is completed, the motor 3 is started, which drives the limit long cylinder 2 to flip 180 degrees, and the clamping plate 7, the push frame 5 and the two groups of cold rolling rollers are flipped 180 degrees accordingly, and the frame edge of the open end of the push frame 5 presses against the top surface of the connecting plate 91, and the connecting plate 91 continues to sink and press against the spring group coil 93 for compression, and the two groups of rectangular blocks 94 sink with the connecting plate 91 and insert into the vertical frame 95 until the bottom end of the rectangular block 94 hits the bottom inner wall of the vertical frame 95, and the push frame 5 is in contact with the connecting plate 91, so the collision of the rectangular block 94 causes the connecting plate 91, the push frame 5 and the two groups of cold rolling rollers to vibrate to a certain extent, so as to help accelerate the removal of the debris attached to the processed area of ​​the cold rolling roller; At the same time, when the rectangular block 94 sinks downward, its bottom end is first inserted into the corresponding limiting groove 97, and the bottom end of the rectangular block 94 presses against the inclined inner wall of the limiting groove 97, forcing the end of the cross bar 96 hinged with the blocking plate 98 to be pulled into the vertical frame 95, and the spring coil 99 is stretched, thereby locking the hinged end of the blocking plate 98 and making it difficult to deflect arbitrarily, so as to prevent the cold rolling roller from falling off due to vibration and rolling out of the bottom frame 1. Combining the second and third embodiments, it can be known that as the connecting plate 91 sinks and the push frame 5 turns over to a straight state, the two groups of cold rolling rollers that have turned over can be processed. After the cold rolling roller turning surface is also processed, the cylinder 4 is started again, and the push frame 5 is pulled to reset and move, and the multiple groups of wedge-shaped stop blocks 501 move synchronously. The wedge-shaped stop blocks 501 first break away from the wedge-shaped stop cylinder 810, and under the rebound force of the spring damping shock absorber 87, the wedge-shaped stop cylinder 810, the disc 88 and the multiple groups of sliding frames 89 are forced to reset and move to the outside of the cylinder 81. The sliding frame 89 moves relative to the sliding shaft 84 again, causing the multiple groups of stop plates 83 to be pushed out of the cylinder 81 and lose the clamping of the cold rolling roller ends together, thereby assisting the two groups of cold rolling rollers to automatically fall off and unload; As the push frame 5 moves linearly, its end gradually falls off the top of the connecting plate 91, and the connecting plate 91 loses the pressure and resets under the rebound force of the spring coil 1 93, the two groups of rectangular blocks 94 rise synchronously with the connecting plate 91, and the rectangular blocks 94 are separated from the inside of the limiting groove 97, and the cross bar 96 is reset by the rebound force of the spring coil 2 99, and the end of the cross bar 96 hinged with the baffle plate 98 moves toward the outside of the frame 95, and the baffle plate 98 loses the lock, so that the cold rolling roller falls off and slides down the inclined surface, and the front and rear ends of the cold rolling roller respectively press the two groups of baffle plates 98, the deflection angles of the two groups of baffle plates 98 are deflected according to the length of the cold rolling roller, and the opening and closing angles of the two groups of baffle plates 98 are adaptively changed according to the length of the cold rolling roller, so as to achieve stable feeding of the cold rolling roller.

[0021] When the present invention is in use, firstly, the two groups of cold rolling rollers are respectively unloaded to the mountain-shaped clamping frame 6, and the middle section of the bottom surface of the cold rolling rollers is fitted with the bottom curved surface of the frame, and the two groups of clamping plates 7 are respectively located at the front and rear ends of the cold rolling rollers, and then the cylinder 4 is started, which uses the push rod to push the push frame 5 to move, and the push frame 5 and the two groups of clamping plates 7 move relative to each other left and right, and the wedge-shaped stop block 501 moves toward the adjacent conical stop block 702, and the inclined surface of the wedge-shaped stop block 501 continuously presses the side inclined surface of the conical stop block 702, forcing the conical stop block 702 and the clamping plate 7 to move under the pressure, then the slide bar 202 also moves along the inside of the slide groove 201, and the two groups of clamping plates 7 approach each other. At the same time, the limiting mechanisms 8 on the surfaces of the two groups of clamping plates 7 that are opposite to each other also press against the front and rear ends of the two groups of cold rolling rollers, thereby realizing the centering positioning of the two groups of cold rolling rollers and the preliminary pressing of the ends; Secondly, along with the continuous pushing of the push frame 5, the wedge-shaped abutment block 501 moves to the wedge-shaped abutment cylinder 810. Similarly, the tip of the wedge-shaped abutment block 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 toward the inside of the cylinder 81, and the T-shaped insertion rod 86 presses against the spring damping shock absorber 87 to be compressed, and the four groups of abutment plates 83 are pulled at the ends and inserted into the inside of the cylinder 81 at the same time. The four groups of abutment plates 83 extend outside the cylinder 81 and press against the outer wall of the end of the cold rolling roller respectively, so as to further clamp and limit the end of the cold rolling roller. Next, when the upper half of the cold rolling roller is processed, the motor 3 is started, which drives the limit cylinder 2 to flip 180 degrees, and the clamping plate 7, the push frame 5 and the two groups of cold rolling rollers are flipped 180 degrees accordingly, and the frame edge of the open end of the push frame 5 presses against the top surface of the connecting plate 91, and the connecting plate 91 continues to sink and press against the spring group coil 93 for compression, and the two groups of rectangular blocks 94 sink with the connecting plate 91 and insert into the vertical frame 95 until the bottom end of the rectangular block 94 hits the bottom inner wall of the vertical frame 95, and the push frame 5 is in contact with the connecting plate 91, so the rectangular block 94 hits the connecting plate 91, so that the connecting plate 91, the push frame 5 and the two groups of cold rolling rollers are vibrated to a certain extent, so as to help accelerate the removal of the debris attached to the processed area of ​​the cold rolling roller; Finally, the two groups of turned cold rolling rollers can be processed. After the turning surface of the cold rolling rollers is also processed, the cylinder 4 is started again, and the pulling push frame 5 is reset and moved, and the multiple groups of wedge-shaped resistance blocks 501 move synchronously. The wedge-shaped resistance blocks 501 first disengage from the wedge-shaped resistance cylinder 810, and under the rebound force of the spring damping shock absorber 87, the wedge-shaped resistance cylinder 810, the disc 88 and the multiple groups of sliding frames 89 are forced to reset and move to the outside of the cylinder 81. The sliding frame 89 moves relative to the sliding shaft 84 again, causing the multiple groups of resistance plates 83 to be pushed out of the cylinder 81 and lose their clamping on the end of the cold rolling roller together, thereby assisting the two groups of cold rolling rollers to automatically fall off and unload.
