Description

Technical Field

[0001] The present invention relates to the technical field of metal processing, and more particularly to the technical field of metal strip cutting, in particular to a rolling shear for metal strip cutting. Background Art

[0002] In the field of metal processing, it is usually necessary to use cutting devices to remove metal scraps to make the metal materials meet the design and process requirements. For example, metal strips such as stainless steel, carbon steel, aluminum, copper, and titanium alloys need to be cut during processing to make them suitable for use. Rolling shears are generally used for strip cutting operations.

[0003] For example, the patent with authorization announcement number CN208246919U discloses a plate rolling shear, which belongs to the field of rolling shears and aims to provide a plate rolling shear that can adjust the distance between the upper disc knife and the lower disc knife according to different plate thicknesses, so that the equipment has strong production applicability. Its technical points are: a plate rolling shear, including a frame, on which a feeding mechanism and a rolling shear mechanism are arranged in sequence along the conveying direction of the plate, the rolling shear mechanism includes an upper knife roller, a lower knife roller and a rolling shear group symmetrically arranged up and down, the upper knife roller is rotatably connected to the frame; a drive motor is provided on the lower side of the lower knife roller on the frame, the drive motor is connected to the upper knife roller through a belt, and the lower knife roller rotates synchronously with the upper knife roller through a linkage component; the frame is provided with an adjustment component for adjusting the height of the lower knife roller. It is suitable for rolling shearing of plates such as PCB boards;

[0004] Another example is the patent with authorization announcement number CN208289092U, which discloses a cutting mechanism of a rolling shearing machine. The key technical solutions include a base, a support plate and a support platform are respectively provided on both sides of the base, an upper rotating shaft and a lower rotating shaft are rotatably connected between the support plate and the support platform, and are parallel to each other and driven by a cutting motor. The upper rotating shaft and the lower rotating shaft are respectively fixedly sleeved with two upper blades and two lower blades. The support plate and the support platform are respectively provided with adjustment holes and adjustment cavities on the opposite sides. The adjustment holes and the adjustment cavities are both provided with adjustment blocks. The adjustment blocks are provided with a rotation hole for one end of the upper rotating shaft to be inserted into. The upper end surface of the adjustment block is fixedly connected to a lifting screw that passes through the support plate or the support platform. The upper end surfaces of the adjustment plate and the adjustment platform are both tightly attached to the lifting handwheels that are threadedly connected to the lifting screw. By rotating the two lifting handwheels, the gap between the upper rotating shaft and the lower rotating shaft can be increased, thereby facilitating the metal coil to pass through the gap between the upper blade and the lower blade, saving time and effort.

[0005] However, considering the actual production process of metal strip cutting, the current metal strip rolling shears still have certain drawbacks, such as:

[0006] 1. Although the rolling shear machine adopts an upper and lower rolling shear group that can adjust the spacing, it is difficult to transmit the power between the upper and lower shear groups. Some existing technologies use gears for transmission, but it cannot ensure that the gear transmission is always engaged after the spacing is arbitrarily adjusted, so the spacing adjustment range is limited;

[0007] 2. The shearing shears of the rolling shear machine have a fixed structure during use, which makes it difficult to adjust the position of the shears according to the needs.

[0008] 3. The hob structure is usually fixed directly on the outside of the cutter roller, which is not convenient for disassembly and replacement, which will extend maintenance time and reduce processing efficiency.

[0009] Therefore, we propose a rolling shear for metal strip cutting to solve the above problems. Summary of the Invention

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention, so that the implementation process of how this application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0054] In order to solve the problems existing in the prior art, please refer to Figure 1-8 , the present invention provides the following technical solutions:

[0055] A rolling shear for cutting metal strips, comprising: a frame 1, a table 2, a gear box 3, a protective shell 4, a support plate 5, a slide 6, a fixing bolt 7, a fixing block 8, an adjusting block 9, a pressing plate 10, a first adjusting rod 11, an adjusting hand wheel 12, a lower knife group 13, an upper knife group 14, a lower rotating shaft 15, a connecting wheel 16, a transmission chain 17, a transmission gear 18, a driving shaft 19, an upper rotating shaft 20, a rotating arm 21, a first gear 22, a second Gear 23, connecting plate 24, horizontal shaft 25, third gear 26, fourth gear 27, knife roller 28, fixed end 29, slot 30, standard section 31, knife section 32, fitting block 33, fitting buffer pad 34, block 35, limiting slot 36, rear blade 37, front blade 38, fixing pin 39, fixing plate 40, vertical rod 41, second adjustment rod 42, adjustment seat 43, support rod 44, support rod 45 and roller 46;

[0056] Among them: Figure 1 and Figure 2In the figure, a table 2 is integrally provided on the top surface of the frame 1, and a gear box 3 and a support plate 5 with adjustable spacing are provided on the left and right sides of the top of the table 2. A lower knife group 13 and an upper knife group 14 for shearing are provided between the gear box 3 and the support plate 5. A fixing block 8 is fixed to the inner bottom of the gear box 3 and the support plate 5. An adjusting block 9 is provided on the inner top of the gear box 3 and the support plate 5. The inner sides of the fixing block 8 and the adjusting block 9 are used to connect the upper knife group 14 and the lower knife group 13 respectively. A slide groove 6 is symmetrically provided on the right side of the table 2, and a fixing bolt 7 is slidably connected to the inner side of the slide groove 6. The bottom of the support plate 5 is fixed to the table 2 through the fixing bolt 7. A pressing plate 10 is fixedly installed on the top of the gear box 3 and the support plate 5. A first adjusting rod 11 connected to the top of the adjusting block 9 is provided on the inner side of the pressing plate 10. The outer side of the first adjusting rod 11 is connected to the adjusting hand wheel 12 located above the pressing plate 10.

[0057] In a specific application scenario: the height position of the adjusting block 9 can be adjusted above the table 2 by rotating the adjusting hand wheel 12, thereby adjusting the height of the spacing between the fixed block 8 and the adjusting block 9, and the upper knife group 14 and the lower knife group 13 are respectively installed on the inner sides of the fixed block 8 and the adjusting block 9, thereby facilitating the adjustment of the spacing between the lower knife group 13 and the upper knife group 14 according to the thickness of the metal strip. At the same time, the support plate 5 can be adjusted left and right above the table 2, and the sliding of the fixing bolt 7 inside the slide groove 6 makes it easy to fix the support plate 5 above the table 2 for overall installation. A protective shell 4 is fixed to the outside of the gear box 3 to protect its internal transmission components for safety protection.

[0058] The above technical solution is adopted: it is convenient to use the adjustable block 9 to drive the height of the lower knife group 13 to move up and down, so as to adjust the height between the lower knife group 13 and the upper knife group 14, and can adapt to cutting metal strips of different thicknesses.

[0059] Among them: Figure 3 and Figure 4 In the figure, the fixed block 8 inside the gear box 3 and the adjusting block 9 are respectively connected to the lower rotating shaft 15 and the upper rotating shaft 20. The end of the lower rotating shaft 15 is connected to a power mechanism for driving. The power mechanism includes a connecting wheel 16, a transmission chain 17, a transmission gear 18 and a drive shaft 19. The connecting wheel 16 is fixedly connected to the top of the lower rotating shaft 15, the outer side of the connecting wheel 16 is connected to the transmission chain 17, the transmission gear 18 is connected to the bottom inner side of the transmission chain 17, and the middle part of the transmission gear 18 is connected to the drive shaft 19;

[0060] In a specific application scenario: the drive shaft 19 is the output shaft of the motor installed at the bottom inner side of the gear box 3. Through the fixed connection between the drive shaft 19 and the transmission gear 18, the rotation of the drive shaft 19 synchronously drives the transmission gear 18 to rotate. Since the transmission gear 18 is connected to the connecting wheel 16 through the transmission chain 17, the lower rotating shaft 15 is driven to rotate through the connecting wheel 16, so that the lower rotating shaft 15 drives the upper knife group 14 to rotate. At the same time, the inner side of the adjusting block 9 is connected to the upper rotating shaft 20, and the inner side of the upper rotating shaft 20 is connected to the lower knife group 13, so that the lower knife group 13 can rotate for easy shearing.

[0061] The above technical solution is adopted: the transmission chain 17 is used to transmit the power between the driving shaft 19 and the lower rotating shaft 15, so that the lower cutter group 13 can be rotated to facilitate the rolling shear drive.

[0062] Among them: Figure 3 、 Figure 4 and Figure 5 The second gear 23 is arranged on the outer side of the upper rotating shaft 20, and a linkage mechanism that can be adjusted in real time is provided between the lower rotating shaft 15 and the upper rotating shaft 20. The linkage mechanism includes a rotating arm 21, a first gear 22, a second gear 23, a connecting plate 24, a horizontal shaft 25, a third gear 26 and a fourth gear 27. The rotating arm 21 is rotatably connected to the outer side of the upper rotating shaft 20 through a bearing. The middle part of the upper rotating shaft 20 is fixedly installed with the first gear 22 located on the inner side of the rotating arm 21, the second gear 23 is rotatably connected to the outer end of the rotating arm 21, and the outer end of the second gear 23 is rotatably connected to the connecting plate 24. The horizontal shaft 25 is rotatably connected to the bottom end of the connecting plate 24. The third gear 26 is fixed to the middle part of the horizontal shaft 25, and the fourth gear 27 is fixedly connected to the middle part of the lower rotating shaft 15. The fourth gear 27, the third gear 26, the second gear 23 and the first gear 22 are meshed and connected in sequence. The second gear 23 is arranged to rotate along the rotating arm 21 on the outer side of the upper rotating shaft 20, and a linkage structure is formed between the rotating arm 21 and the connecting plate 24.

[0063] In a specific application scenario: when the lower rotating shaft 15 is driven by the driving shaft 19, since the fourth gear 27 is fixed to the outer middle part of the lower rotating shaft 15, the fourth gear 27, the third gear 26, the second gear 23 and the first gear 22 are meshed in sequence to make the lower rotating shaft 15 and the upper rotating shaft 20 interlock, so that the lower rotating shaft 15 and the upper rotating shaft 20 rotate in opposite directions, so as to drive the reverse rotation between the lower knife group 13 and the upper knife group 14, so as to facilitate the use of rolling shears. At the same time, when the adjusting block 9 is raised and lowered by adjusting the hand wheel 12, the raising and lowering of the adjusting block 9 will simultaneously drive the upper rotating shaft 20 to rise and fall, wherein the third gear 26 is rotatably connected to the inner side of the gear box 3 through the horizontal shaft 25, and the upper part of the horizontal shaft 25 is rotatably connected to the connecting plate 24, connecting The top of the plate 24 is rotatably connected to the rotating arm 21, and the tail end of the rotating arm 21 is rotatably sleeved on the outside of the upper rotating shaft 20. When the upper rotating shaft 20 is lifted or lowered, due to the hinge between the upper rotating shaft 20, the rotating arm 21, the connecting plate 24, the horizontal shaft 25 and the gear box 3, the lifting of the upper rotating shaft 20 automatically causes the rotating arm 21 to rotate. The rotation of the rotating arm 21 causes the top of the connecting plate 24 to rotate, so that the position of the second gear 23 follows the lifting of the upper rotating shaft 20 and moves around the center axis of the upper rotating shaft 20 with the rotating arm 21, so as to ensure that the first gear 22, the second gear 23, the third gear 26 and the fourth gear 27 are always engaged, so as to ensure that the transmission between the upper rotating shaft 20 and the lower rotating shaft 15 is always maintained while the upper rotating shaft 20 is lifted or lowered, so as to facilitate the use of rolling shears;

[0064] The above technical solution is adopted: by rotating the rotating arm 21 on the outside of the upper rotating shaft 20, utilizing the rotation between the rotating arm 21 and the connecting plate 24, and the rotation between the connecting plate 24 and the horizontal shaft 25, when the upper rotating shaft 20 is raised or lowered, the rotating arm 21 follows the rotation, so that the upper rotating shaft 20 is always engaged with the lower rotating shaft 15 through the first gear 22, the second gear 23, the third gear 26 and the fourth gear 27, and is transmitted to the lower rotating shaft 15, so as to facilitate the reverse rotation between the lower rotating shaft 15 and the upper rotating shaft 20, so as to facilitate the use of rolling shears.

[0065] Among them: Figure 1 、 Figure 3 、 Figure 6 and Figure 7In the embodiment, the lower knife group 13 and the upper knife group 14 have the same structure. Both the lower knife group 13 and the upper knife group 14 include a knife roller 28, a fixed end 29, a card slot 30, a standard section 31, a knife section 32, a fitting block 33, a fitting buffer pad 34 and a card block 35. The knife roller 28 is rotatably arranged on the inner side of the gear box 3. The end of the knife roller 28 is connected to a fixed end 29 rotatably arranged on the inner side of the support plate 5. The standard section 31 and the knife section 32 are correspondingly sleeved on the outer side of the knife roller 28. A fitting block 33 which is also sleeved on the outer side of the knife roller 28 is provided between the standard section 31 and the knife section 32. The outer side of the knife section 32 is provided with a sealing block 33 which is also sleeved on the outer side of the knife roller 28. A roller is provided on the side, and a slot 30 is provided inwardly on the side of the knife roller 28. The knife roller 28 is correspondingly engaged with the standard section 31, the knife-mounted section 32 and the fitting block 33 through the slot 30. A fitting buffer pad 34 is fitted on the outer side of the fitting block 33. A clamping block 35 is protruded on the outer side of the fitting block 33. The fitting block 33 is tightly fitted with the standard section 31, the knife-mounted section 32, the knife roller 28 or the fixed end 29 through the fitting buffer pad 34. The fitting block 33 is correspondingly limited and engaged with the standard section 31, the knife-mounted section 32, the knife roller 28 or the fixed end 29 through the fitting buffer pad 34.

[0066] In a specific application scenario: the end of the knife roller 28 is fixedly connected to the lower rotating shaft 15 or the upper rotating shaft 20 inside the fixed block 8 and the adjusting block 9 provided inside the gear box 3, so that the lower knife group 13 and the lower rotating shaft 15 drive the knife roller 28 to rotate. At the same time, the other end of the knife roller 28 is fixedly connected to the fixed end 29, and the fixed end 29 is correspondingly connected to the inner side of the fixed block 8 and the adjusting block 9 provided inside the support plate 5, so that the lower knife group 13 and the upper knife group 14 can roll. At the same time, the surface of the knife roller 28 is symmetrically provided with a card slot 30, and the knife roller 28 can be connected with the standard section 31, the knife section 32 and the fitting block 33 through the card slot 30. The sliding engagement connection is made between them, wherein the fitting block 33 is arranged between the knife roller 28 and the standard segment 31 or the knife-mounted segment 32, the standard segment 31 and the knife-mounted segment 32, and the fixed end head 29 and the standard segment 31 or the knife-mounted segment 32, so that the fitting buffer pad 34 fitted on the side of the fitting block 33 can make the standard segment 31, the knife-mounted segment 32 and the fitting block 33 fit tightly, wherein the knife-mounted segment 32 can be installed in an adjustable position on the outside of the knife roller 28, and other positions are filled through the standard segment 31 to adjust the installation position of the knife-mounted segment 32, so that after the hob is installed on the outside of the knife-mounted segment 32, the width of the metal strip can be cut to the designed size;

[0067] The above technical solution is adopted: by opening a slot 30 on the surface of the knife roller 28, the standard section 31, the knife section 32 and the fitting block 33 can be stably installed, so that they can follow the knife roller 28 for rolling use, and the fitting block 33 can tightly fit the connection between them, which can avoid the existence of gaps causing shaking during rolling, and by assembling the knife section 32 in different positions, it is convenient to change the position of the hob according to the width design size of the metal strip, so as to facilitate the cutting of the metal strip.

[0068] Among them: Figure 6 and Figure 7 In the embodiment, the hob is composed of a rear blade 37 and a front blade 38. The end faces of the rear blade 37 and the front blade 38 are engaged with each other and fixedly connected via a fixing pin 39. The inner side surfaces of the rear blade 37 and the front blade 38 correspond to the limiting grooves 36 provided on the surface of the fitting block 33.

[0069] In a specific application scenario: through the limiting groove 36 that is recessed inwardly on the surface of the blade mounting section 32, the rear blade 37 and the front blade 38 can be engaged with the inner side of the limiting groove 36 through the protruding structure of the inner side wall thereof, so as to facilitate the positioning and assembly of the rear blade 37 and the front blade 38. When the rear blade 37 and the front blade 38 are fitted to the blade mounting section 32, the rear blade 37 and the front blade 38 are engaged with each other at the same time, so that the rear blade 37 and the front blade 38 are fixed by the fixing pin 39, thereby facilitating the use of the rolling shear;

[0070] The above technical solution is adopted: the hob is formed by combining the rear blade 37 and the front blade 38, and the rear blade 37 and the front blade 38 are assembled on the outside of the tool mounting section 32, which is convenient for disassembly and replacement of the hob, so as to facilitate maintenance, reduce downtime and improve processing efficiency.
