In automobile manufacturing, cold-rolled steel is used for body structural parts and panels. Its good strength and formability can meet the safety and appearance requirements of automobiles. When cutting cold-rolled steel, traditional cutting devices usually use a conveying mechanism to transfer the cold-rolled steel so that it can be sheared and cut later.

[0011] A method for using a compression cutting device for cold-rolled steel processing, the method comprising the following steps: When in use, the cold-rolled steel to be cut is placed on the roller rod on the bracket, and the cold-rolled steel is supported by multiple rollers, thereby reducing the friction when the cold-rolled steel moves, pulling one end of the cold-rolled steel and making it pass through the guide roller and the pressing assembly. At this time, one end of the cold-rolled steel is overlapped on the top of the cutting seat and is located under the pressing plate, and the slider is supported by the elastic force of two third springs in the frame, so that the slider drives the pressure roller to move downward through the bearing, so that the outer wall of the pressure roller is close to the upper surface of the cold-rolled steel, and the lower surface of the cold-rolled steel contacts the guide roller, and the cold-rolled steel is pressed by the pressure roller and the guide roller, so as to play the role of paving the cold-rolled steel and improve the stability of the guide roller in conveying the cold-rolled steel. The thickened cold-rolled steel will push the pressure roller upward, so that the pressure roller drives the two sliders to move upward in the two sliding grooves through the two bearings, and the slider is pressed down with the elastic force of the third spring, so that the height of the pressure roller can be adaptively adjusted according to the thickness of the cold-rolled steel; By controlling the operation of the motor, the output shaft of the motor drives the gear to rotate clockwise, and the gear drives the turntable to rotate counterclockwise through the gear plate, and the turntable drives the sliding column at the edge to slide into the slideway outside the deflection seat. As the sliding column continues to move, it pushes the deflection seat to rotate clockwise, and the deflection seat drives the guide roller to rotate. The guide roller cooperates with the pressure roller to drive the cold-rolled steel to move, so that the cold-rolled steel passes a distance from under the cutting knife. At this time, the turntable drives the limit plate to slide into the limit groove outside the deflection seat. At this time, the deflection seat no longer drives the guide roller to rotate, so that the cold-rolled steel is in a stopped state. During the rotation process, the gear drives the two cams to rotate through the connecting shaft. During the rotation of the cam The two fixing frames will be squeezed downward, and the fixing frames will squeeze the supporting assembly downward, so that the column in the supporting assembly slides inside the sliding sleeve, and the sliding rod inside the column will move downward synchronously, so that the sliding rod drives the pressing plate to first contact the upper surface of the cold-rolled steel. As the pressing plate continues to press downward, the sliding rod squeezes the first spring inside the slide groove, and the elastic force of the first spring supports the sliding rod in the opposite direction, so that the pressing plate below is close to the cold-rolled steel, and cooperates with the cutting seat to support the lower surface of the cold-rolled steel, which plays a role in pressing and limiting the cold-rolled steel, thereby improving the stability of subsequent cutting of the cold-rolled steel. Secondly, the two fixing frames will drive the cutting knife to move downward, so that the cutting knife shears the cold-rolled steel on the cutting seat; After completing the cutting of the cold-rolled steel, the connecting shaft drives the highest point of the two cams to gradually move away from the two fixed frames, and the top of the inner wall of the fixed frame is supported by the elastic force of the second spring, so that the fixed frame drives the column and the cutting knife to move upward, and the cutting knife moves to the top of the cold-rolled steel. The column pulls the bottom slide bar to move upward, and the slide bar drives the pressing plate to move upward and away from the cold-rolled steel. At this time, the pressing state of the cold-rolled steel is released, and the turntable drives the slide column to slide into the slide outside the deflection seat again, so that the deflection seat drives the guide roller to rotate clockwise and transport the cold-rolled steel. The cold-rolled steel passes through the bottom of the cutting knife again, and when the highest point of the cam gradually squeezes the two fixed frames, the fixed frame drives the cutting knife to cut it. This cycle works to achieve the purpose of automatic conveying, pressing and cutting of the cold-rolled steel. The cut cold-rolled steel will fall on the inclined plate and slide down along the inclined part of the inclined plate for collection.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the two cams are driven to rotate by the connecting shaft. During the rotation of the cams, the two fixing frames are squeezed downward, and the fixing frames squeeze the support assembly downward, so that the column in the support assembly slides inside the sliding sleeve, and the sliding rod inside the column moves downward synchronously, so that the sliding rod drives the clamping plate to first contact the upper surface of the cold-rolled steel. As the clamping plate continues to press downward, the sliding rod squeezes the first spring inside the slide groove, and the elastic force of the first spring supports the sliding rod in the opposite direction, so that the lower clamping plate is close to the cold-rolled steel, and cooperates with the cutting seat to support the lower surface of the cold-rolled steel, thereby playing a role in clamping and limiting the cold-rolled steel, thereby improving the stability of subsequent cutting of the cold-rolled steel. Secondly, the two fixing frames drive the cutting knife to move downward, so that the cutting knife shears the cold-rolled steel on the cutting seat, completing the cutting of the cold-rolled steel. After cutting, the connecting shaft drives the highest point of the two cams to gradually move away from the two fixing frames, and the top of the inner wall of the fixing frame is supported by the elastic force of the second spring, so that the fixing frame drives the column and the cutting knife to move upward, and the cutting knife moves to the top of the cold-rolled steel. The column pulls the sliding rod at the bottom to move upward, and the sliding rod drives the pressing plate to move upward and away from the cold-rolled steel. At this time, the pressing state of the cold-rolled steel is released, and the guide roller rotates clockwise and conveys the cold-rolled steel. When the highest point of the cam gradually squeezes the two fixing frames, the fixing frame drives the cutting knife to cut it. This cycle works to achieve the purpose of automatic conveying, pressing and cutting of the cold-rolled steel, prevent the cold-rolled steel from sudden jumping or displacement due to the cutting force, reduce safety hazards and improve cutting accuracy. 2. In the present invention, the cold-rolled steel is supported by multiple rollers, thereby reducing the friction of the cold-rolled steel when it moves. One end of the cold-rolled steel is overlapped on the top of the cutting seat and is located below the pressure plate. The slider is supported by the elastic force of two third springs in the frame, and the slider drives the pressure roller to move downward through the bearing, so that the outer wall of the pressure roller is close to the upper surface of the cold-rolled steel, and the lower surface of the cold-rolled steel is in contact with the guide roller. The cold-rolled steel is pressed by the pressure roller and the guide roller, which plays a role in flattening the cold-rolled steel and improving the stability of the guide roller in conveying the cold-rolled steel. The thickened cold-rolled steel will push the pressure roller upward, so that the pressure roller drives the two sliders to move upward in the two sliding grooves through the two bearings, and the slider is pressed down with the elastic force of the third spring, so that the height of the pressure roller can be adaptively adjusted according to the thickness of the cold-rolled steel, thereby meeting the needs of compacting and conveying cold-rolled steel of different thicknesses.

[0014] The technical solution of the present application will be further described in detail below in conjunction with specific implementation methods.

[0015] like Figure 1-7As shown, the present invention provides a technical solution: a compression cutting device for cold-rolled steel processing, comprising a frame 1, with a bracket 15 and a side plate 17 fixedly connected to both sides of the frame 1, a cutting seat 2 fixedly connected to the middle of the inner wall of the frame 1, a roller 16 rotatably connected to the inside of the bracket 15 through a shaft sleeve, the cold-rolled steel to be cut is placed on the roller 16 on the bracket 15, and the cold-rolled steel is supported by multiple rollers 16, thereby reducing the friction of the cold-rolled steel when it moves; an inclined plate 18 is fixedly connected to the bottom of the inner wall of the side plate 17, and the cut cold-rolled steel will fall on the inclined plate 18 and slide down along the inclined portion of the inclined plate 18 for collection.

[0016] A partition 3 is provided above the cutting seat 2, with both ends of the partition 3 fixed to either side of the inner wall of the frame 1. Two support assemblies 6 are slidably connected through the partition 3. The support assembly 6 includes a column 601, the top of which is fixed to the top of the inner wall of the fixing frame 5. The fixing frame 5 is L-shaped. The column 601 is fixedly connected to a horizontally arranged side wing of the fixing frame 5. The bottom ends of the other longitudinally arranged side wings of the two fixing frames 5 are fixedly mounted with cutting blades 4, which are located above the cutting seat 2. The outer wall of the column 601 is sleeved with a sliding sleeve 605, which is inserted through the partition 3 and fixed by a snap connection. The bottom of the column 601 is provided with a slide groove 602, in which a slide rod 603 is slidably connected. The bottom end of the slide rod 603 passes through the column 601 and is fixed to the top of the pressure plate 7.

[0017] The top of the slide bar 603 is fixedly connected with a first spring 604, and the top of the first spring 604 is fixed to the top of the inner wall of the slide groove 602. The slide bar 603 squeezes the first spring 604 inside the slide groove 602, and the elastic force of the first spring 604 reversely supports the slide bar 603, so that the pressing plate 7 below is close to the cold-rolled steel, and cooperates with the cutting seat 2 to support the lower surface of the cold-rolled steel, which plays a role in pressing and limiting the cold-rolled steel, thereby improving the stability of subsequent cutting of the cold-rolled steel; the outer shell of the column 601 is connected with a second spring 606, the bottom end of the second spring 606 is fixed to the partition 3, and the top end of the second spring 606 is fixedly connected to the top of the inner wall of the fixing frame 5. The top of the inner wall of the fixing frame 5 is supported by the elastic force of the second spring 606, so that the fixing frame 5 drives the column 601 and the cutting knife 4 to move upward, and the cutting knife 4 moves to the top of the cold-rolled steel. The column 601 pulls the bottom slide bar 603 to move upward, and the slide bar 603 drives the clamping plate 7 to move upward to make it away from the cold-rolled steel, so as to release the clamping state of the cold-rolled steel.

[0018] The fixing frame 5 presses the column 601 downward, causing the column 601 to slide inside the sliding sleeve 605, and the sliding rod 603 inside the column 601 will move downward synchronously, causing the sliding rod 603 to drive the pressing plate 7 to contact the upper surface of the cold-rolled steel. The sliding sleeve 605 limits the position of the column 601, improving the stability of the vertical movement of the sliding rod 603 and the pressing plate 7 below driven by the column 601; One side of the frame 1 is fixedly connected to a base 8, to which a motor 9 is fixedly connected. The output shaft of the motor 9 is fixedly connected to a push assembly 10. The two ends of the push assembly 10 are installed through the frame 1, and the middle part of the push assembly 10 overlaps the top of the two fixed frames 5. The push assembly 10 includes a connecting shaft 101, the outer ends of which are rotatably connected to the frame 1 through shaft sleeves. One end of the connecting shaft 101 passes through the frame 1 and is fixedly connected to a gear 103, one end of which is fixedly connected to the output shaft of the motor 9. Cams 102 are fixed on both sides of the outer wall of the connecting shaft 101. The lowest end of the cam 102 overlaps the top of the fixed frame 5. When the highest point of the cam 102 gradually squeezes the two fixed frames 5, the fixed frames 5 drive the cutting blade 4 to cut it. When the highest point of the cam 102 gradually moves away from the fixed frame 5, the cutting blade 4 moves upward to facilitate the next cutting of the cold-rolled steel.

[0019] The push assembly 10 extends through one side of the frame 1 and is connected to a drive assembly 11. A guide roller 12 is fixedly connected to one side of the drive assembly 11. The ends of the guide roller 12 are rotatably connected to the inner wall of the frame 1 via shaft sleeves. The drive assembly 11 includes a turntable 111. The middle portion of the turntable 111 is rotatably connected to one side of the frame 1 via shaft sleeves. A gear plate 114 and a limit plate 112 are fixedly connected to the two side surfaces of the turntable 111. A sliding post 113 is fixed to the edge of the turntable 111. The gear plate 114 meshes with the gear 103. A deflection seat 115 is provided outside the limit plate 112. The middle portion of the deflection seat 115 is fixed to the end of the guide roller 12 that extends outside the frame 1. Four slides 116 and four limit slots 117 are arranged in an staggered manner outside the deflection seat 115. The angle between two adjacent slides 116 and two limit slots 117 is ninety degrees. The slide 116 is a straight slide and points to the center of the deflection seat 115. The limit slot 117 is arc-shaped and the outer edge is between the two slides 116. The turntable 111 drives the limit plate 112 to slide into the limit slot 117 outside the deflection seat 115. As the turntable 111 rotates, the slide column 113 can be inserted into the slide 116, and the outer edge of the limit plate 112 can match and fit with the limit slot 117. At this time, the deflection seat 115 no longer drives the guide roller 12 to rotate, so that the cold-rolled steel is in a stopped state, so as to facilitate the subsequent precise cutting of the cold-rolled steel.

[0020] A downward pressing assembly 13 is provided above the guide roller 12, and sliding grooves 14 are respectively provided on both sides of the inner wall of the frame 1 corresponding to the two ends of the guide roller 12. The downward pressing assembly 13 includes a pressure roller 131, and bearings 132 are sleeved at both ends of the pressure roller 131. A slider 133 is fixedly connected to the outside of the bearing 132. The slider 133 is slidably connected in the sliding groove 14. A limiting rod 134 is slidably installed through the middle of the slider 133. The two ends of the limiting rod 134 are fixed to the upper and lower inner walls of the sliding groove 14. A third spring 135 is connected to the outer surface of the limiting rod 134. The third spring 135 is located between the inner wall of the sliding groove 14 and the slider 133. The slider 133 is supported by the elastic force of the two third springs 135 in the frame 1, so that the slider 133 drives the pressure roller 131 to move downward through the bearing 132, so that the outer wall of the pressure roller 131 is in close contact with the upper surface of the cold-rolled steel, and the lower surface of the cold-rolled steel is in contact with the guide roller 12. The cold-rolled steel is pressed by the pressure roller 131 and the guide roller 12, which plays a role in flattening the cold-rolled steel and improving the stability of the guide roller 12 in conveying the cold-rolled steel.

[0021] A method for using a compression cutting device for cold-rolled steel processing, the method comprising the following steps: During use, the cold-rolled steel to be cut is placed on the roller 16 on the bracket 15, and the cold-rolled steel is supported by multiple rollers 16, thereby reducing the friction of the cold-rolled steel when it moves, pulling one end of the cold-rolled steel and passing it through the guide roller 12 and the down-pressing assembly 13. At this time, one end of the cold-rolled steel is overlapped on the top of the cutting seat 2 and is located below the pressure plate 7. The slider 133 is supported by the elastic force of the two third springs 135 in the frame 1, so that the slider 133 drives the pressure roller 131 to move downward through the bearing 132, so that the outer wall of the pressure roller 131 is close to the upper surface of the cold-rolled steel, and the lower surface of the cold-rolled steel contacts the guide roller 12. The cold-rolled steel is pressed by the pressure roller 131 and the guide roller 12, which plays a role in flattening the cold-rolled steel and improving the stability of the guide roller 12 in conveying the cold-rolled steel.

[0022] The thickened cold-rolled steel will push up the pressure roller 131, so that the pressure roller 131 drives the two sliders 133 to move upward in the two sliding grooves 14 through the two bearings 132, and the elastic force of the third spring 135 presses the sliders 133 downward, so that the height of the pressure roller 131 can be adaptively adjusted according to the thickness of the cold-rolled steel.

[0023] By controlling the operation of the motor 9, the output shaft of the motor 9 drives the gear 103 to rotate clockwise, and the gear 103 drives the turntable 111 to rotate counterclockwise through the toothed disc 114. The turntable 111 drives the sliding column 113 at the edge to slide into the slideway 116 outside the deflection seat 115. As the sliding column 113 continues to move, it pushes the deflection seat 115 to rotate clockwise, and the deflection seat 115 drives the guide roller 12 to rotate. The guide roller 12 cooperates with the pressure roller 131 to drive the cold-rolled steel to move, so that the cold-rolled steel passes a distance from the bottom of the cutting knife 4; at this time, the turntable 111 drives the limit plate 112 to slide into the limit groove 117 outside the deflection seat 115. At this time, the deflection seat 115 no longer drives the guide roller 12 to rotate, so that the cold-rolled steel is in a stopped state.

[0024] During the rotation of gear 103, the two cams 102 are driven to rotate through the connecting shaft 101. During the rotation of cam 102, the two fixing frames 5 are squeezed downward, and the fixing frame 5 squeezes the support assembly 6 downward, so that the column 601 in the support assembly 6 slides inside the sliding sleeve 605, and the sliding rod 603 inside the column 601 will move downward synchronously, so that the sliding rod 603 drives the clamping plate 7 to first contact the upper surface of the cold-rolled steel; as the clamping plate 7 continues to press downward, the sliding rod 603 squeezes the first spring 604 inside the slide groove 602, and the elastic force of the first spring 604 reversely supports the sliding rod 603, so that the lower clamping plate 7 is close to the cold-rolled steel, and cooperates with the cutting seat 2 to support the lower surface of the cold-rolled steel, which plays a role in clamping and limiting the cold-rolled steel, thereby improving the stability of subsequent cutting of the cold-rolled steel; secondly, the two fixing frames 5 will drive the cutting knife 4 to move downward, so that the cutting knife 4 shears the cold-rolled steel on the cutting seat 2.

[0025] After completing the cutting of the cold-rolled steel, the connecting shaft 101 drives the highest point of the two cams 102 to gradually move away from the two fixed frames 5, and the top of the inner wall of the fixed frame 5 is supported by the elastic force of the second spring 606, so that the fixed frame 5 drives the column 601 and the cutting knife 4 to move upward, and the cutting knife 4 moves to the top of the cold-rolled steel, and the column 601 pulls the bottom slide bar 603 to move upward, and the slide bar 603 drives the pressing plate 7 to move upward and away from the cold-rolled steel, at this time releasing the clamping state of the cold-rolled steel; the turntable 111 drives the slide column 113 to slide into the slideway 116 outside the deflection seat 115 again, so that the deflection seat 115 drives the guide roller 12 to rotate clockwise and convey the cold-rolled steel, and the cold-rolled steel passes through the bottom of the cutting knife 4 again, and when the highest point of the cam 102 gradually squeezes the two fixed frames 5, the fixed frame 5 drives the cutting knife 4 to cut it. The cold rolled steel is automatically conveyed, compacted and cut by such a cycle. The cut cold rolled steel falls on the inclined plate 18 and slides down along the inclined surface of the inclined plate 18 for collection.

8. A method for using a pressing and cutting device for cold-rolled steel processing, according to any one of claims 1 to 7, characterized in that: The method of use comprises the following steps: When in use, the cold-rolled steel to be cut is placed on the roller (16) on the bracket (15), and the cold-rolled steel is supported by multiple rollers (16), thereby reducing the friction force when the cold-rolled steel moves, pulling one end of the cold-rolled steel and passing it through the guide roller (12) and the pressing assembly (13). At this time, one end of the cold-rolled steel is overlapped on the top of the cutting seat (2) and is located below the pressing plate (7). The slider (133) is supported by the elastic force of the two third springs (135) in the frame (1), so that the slider (133) drives the pressing roller (131) to move downward through the bearing (132), so that the outer wall of the pressing roller (131) is tightly attached to the outer wall of the pressing roller (131). The upper surface of the cold-rolled steel and the lower surface of the cold-rolled steel are in contact with the guide roller (12), and the cold-rolled steel is pressed by the pressure roller (131) and the guide roller (12), so as to flatten the cold-rolled steel and improve the stability of the guide roller (12) in conveying the cold-rolled steel. The thickened cold-rolled steel will push up the pressure roller (131), so that the pressure roller (131) drives the two sliders (133) to move upward in the two sliding grooves (14) through the two bearings (132), and the slider (133) is pressed downward by the elastic force of the third spring (135), so that the height of the pressure roller (131) can be adaptively adjusted according to the thickness of the cold-rolled steel; By controlling the motor (9) to work, the output shaft of the motor (9) drives the gear (103) to rotate clockwise, and the gear (103) drives the turntable (111) to rotate counterclockwise through the toothed disc (114). The turntable (111) drives the sliding column (113) at the edge to slide into the slideway (116) outside the deflection seat (115). As the sliding column (113) continues to move, it pushes the deflection seat (115) to rotate clockwise, and the deflection seat (115) drives the guide roller (12). The guide roller (12) cooperates with the pressure roller (131) to drive the cold-rolled steel to move, so that the cold-rolled steel passes a distance from the bottom of the cutting knife (4). At this time, the turntable (111) drives the limit plate (112) to slide into the limit groove (117) outside the deflection seat (115). At this time, the deflection seat (115) no longer drives the guide roller (12) to rotate, so that the cold-rolled steel is in a stopped state. During the rotation process, the gear (103) drives the two cams ( 102) rotates, and the cam (102) will squeeze the two fixing frames (5) downward during the rotation process, and the fixing frames (5) will squeeze the support assembly (6) downward, so that the column (601) in the support assembly (6) slides inside the sliding sleeve (605), and the sliding rod (603) inside the column (601) will move downward synchronously, so that the sliding rod (603) drives the pressing plate (7) to first contact with the upper surface of the cold-rolled steel. As the pressing plate (7) continues to press downward, the sliding rod (603) squeezes The first spring (604) inside the pressing groove (602) supports the sliding rod (603) in the reverse direction through the elastic force of the first spring (604), so that the pressing plate (7) below is close to the cold-rolled steel, and cooperates with the cutting seat (2) to support the lower surface of the cold-rolled steel, playing the role of pressing and limiting the cold-rolled steel, thereby improving the stability of the subsequent cutting of the cold-rolled steel. Secondly, the two fixing frames (5) will drive the cutting knife (4) to move downward, so that the cutting knife (4) can shear the cold-rolled steel on the cutting seat (2); After the cutting of the cold-rolled steel is completed, the connecting shaft (101) drives the highest points of the two cams (102) to gradually move away from the two fixing frames (5), and the top of the inner wall of the fixing frame (5) is supported by the elastic force of the second spring (606), so that the fixing frame (5) drives the column (601) and the cutting knife (4) to move upward, and the cutting knife (4) moves to the top of the cold-rolled steel. The column (601) pulls the bottom slide bar (603) to move upward, and the slide bar (603) drives the pressing plate (7) to move upward and away from the cold-rolled steel. At this time, the pressing state of the cold-rolled steel is released, and the turntable (111) drives the slide bar (113) slides into the slideway (116) outside the deflection seat (115) again, so that the deflection seat (115) drives the guide roller (12) to rotate clockwise and convey the cold-rolled steel. The cold-rolled steel passes through the bottom of the cutting knife (4) again. When the highest point of the cam (102) gradually squeezes the two fixed frames (5), the fixed frames (5) drive the cutting knife (4) to cut it. This cycle works to achieve the purpose of automatically conveying, pressing and cutting the cold-rolled steel. The cut cold-rolled steel will fall on the inclined plate (18) and slide down along the inclined surface of the inclined plate (18) for collection.
