Description

Technical Field

[0001] The present invention relates to the technical field of steel strip cutting equipment, and in particular to a cutting equipment and a cutting method for a steel strip production line. Background Art

[0002] During the production of steel strips, cutting equipment is required for segmentation and rewinding. Steel strip cutting equipment is a special machine used to precisely cut metal steel strips. It is widely used in steel processing, automobile manufacturing, home appliance production, construction industry and other fields.

[0003] Currently, some cutting equipment uses disc cutters to cut conveyor belts in straight lines. However, in specialized stamping and bending processes, when the workpiece end face requires an angled cut, straight cutting methods are insufficient. In these cases, a cutter with a specific angle or specialized cutting equipment must be replaced, which is a cumbersome and inconvenient process. Summary of the Invention

[0004] The purpose of the present invention is to provide a cutting device and a cutting method for a steel strip production line to solve the problem raised in the above background technology that when the end face of the workpiece requires a bevel cut, a cutter with a specific angle or special cutting equipment must be replaced, and the operation process is relatively cumbersome and lacks convenience.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a cutting device and a cutting method for a steel strip production line, comprising a machine body and a disc cutter installed on the upper side of the machine body, an angle adjustment assembly being provided on the upper side of the machine body, the angle adjustment assembly comprising: a shaft rod being installed on the upper side of the disc cutter, for driving the disc cutter to rotate and realize angle offset; a connecting rod, one end of which is fixedly connected to the outer side of the shaft rod; a swinging mechanism being located on the front side of the disc cutter, the swinging mechanism comprising a lever for moving the connecting rod, and the shaft rod being driven to rotate by the connecting rod during the swinging process; a rotating mechanism being arranged at the front bottom of the lever, and the rotating mechanism driving the lever to swing when rotating.

[0006] Furthermore, a limiting groove is provided on the top of the shifting rod, and a limiting ball is slidably connected inside the limiting groove. The limiting ball slides back and forth inside the limiting groove as the shifting rod swings.

[0007] Furthermore, a support rod is fixedly connected to the middle portion of the rear side of the shifting rod, and the shifting rod swings around the support rod as the axis point.

[0008] Furthermore, a supporting plate is provided at the bottom end of the connecting rod, and a supporting block is fixedly connected to the bottom end of the supporting plate.

[0009] Furthermore, the rotation mechanism includes: a turntable, which is arranged on the front side of the shift rod, and a fixed column is fixedly connected to the rear side of the turntable, and the fixed column is slidably connected to the bottom of the shift rod. When the turntable rotates, it drives the fixed column to move at the bottom of the shift rod, causing the bottom of the shift rod to swing; a locking member, which is located on the front side of the turntable, and the outer shell of the locking member is provided with a shell, and the front side of the shell is rotatably connected to a knob. The locking member is provided to play a locking role to prevent the turntable from rotating in the opposite direction.

[0010] Furthermore, the locking member includes: a ratchet, which is rotatably connected to the inside of the shell parallel to the lever, an axial hole is opened inside the ratchet, and a pawl is engaged on the outside of the ratchet, which utilizes the characteristics of the ratchet and the pawl to perform a locking function; a rotating rod, which is installed inside the shell and fixedly sleeved in the axial hole, and the two ends of the rotating rod are respectively fixedly connected between the knob and the turntable, and the turntable can be driven to rotate coaxially by turning the knob.

[0011] Furthermore, a reciprocating mechanism is provided at the top end of the disc cutter for carrying the disc cutter to move back and forth to cut the steel strip.

[0012] Furthermore, the reciprocating mechanism includes a bidirectional screw rod installed at the top end of the disc cutter, and a movable sleeve is provided on the outer side of the bidirectional screw rod. The lower side of the movable sleeve is fixedly installed on the upper side of the disc cutter. When the bidirectional screw rod rotates, the disc cutter can be driven to reciprocate through the movable sleeve.

[0013] Furthermore, both ends of the bidirectional screw rod are rotatably connected to a mounting bracket for mounting the disc cutter, and the upper side of the mounting bracket is fixedly mounted on the lower side of the shaft rod.

[0014] Furthermore, a collecting trough is slidably connected to the top of the machine body and is located at the lower side of the disc cutter. Waste chips generated during cutting fall directly into the collecting trough to avoid being scattered on the machine body.

[0015] Furthermore, an offset mechanism is provided on the front side of the collecting trough, and the collecting trough is connected to the angle adjustment assembly through the offset mechanism. As the angle adjustment assembly rotates, the collecting trough is synchronously offset.

[0016] A cutting method for a cutting device used in a steel strip production line comprises the following steps: Step 1: Turn the knob counterclockwise to drive the fixed column to rotate in a circle through the rotating rod. At the same time, observe the indicator position on the knob to understand the rotation angle; Step 2: As the fixed column rotates in a circle, it slides at the bottom of the lever. Due to the restriction of the support rod, the lever swings as the fixed column rotates. Step 3: When the top of the lever swings, the limiting ball and the arc seat drive the connecting rod and the shaft to have an angular deviation; Step 4: After adjusting the required angle, stop turning the knob and lock it with the locking piece, then start the disc cutter and start cutting.

[0017] Compared with the prior art, the present invention has the following beneficial effects: During normal cutting, the angle adjustment assembly is in its initial state, and the disc cutter cuts the steel strip at right angles. To achieve bevel cutting, rotating the knob drives the turntable and fixed column, which in turn deflects the top of the lever. This, in turn, drives the shaft via a connecting rod to produce angular deflection, thereby adjusting the disc cutter's cutting angle. This structure enables rapid switching between straight and bevel cutting, supports multi-angle bevel adjustment, and is simple and quick to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figures 1 to 11 The present invention provides a cutting device and cutting method for a steel strip production line: a cutting device and cutting method for a steel strip production line, comprising a machine body 1 and a disc cutter 8 mounted on the upper side of the machine body 1. The machine body 1 is a cutting machine tool, which is a machine tool for cutting, shearing or trimming various materials and is widely used in industries such as metal processing. A support frame 2 is fixedly connected to the left side of the machine body 1. A fixing frame is installed on the upper side of the support frame 2. The fixing frame consists of two lockable clamps and a hinge. The two clamps are connected by a hinge. The chain is hinged, and a winding drum 3 is installed between the two fixed frames for winding the cut steel strip. When the winding drum 3 is completed, the fixed frame is opened, the winding drum 3 can be replaced, and then the winding operation can be performed again. The disc cutter 8 is a common cutting tool, which is widely used in various industrial fields. It is usually made of high-strength steel or carbide and realizes the cutting action by high-speed rotation. A smooth-edged disc cutter is used here, which is mainly used in situations where a smooth incision is required to ensure a smooth incision after the steel strip is cut and reduce the appearance of burrs.

[0032] A plurality of conveying mechanisms 4 for conveying steel strips are symmetrically fixedly installed on the machine body 1. The conveying mechanism 4 includes a side frame 401. A slot is provided inside the side frame 401. A lifting block 402 is slidably connected inside the slot. The upper side of the lifting block 402 is rotatably connected with a screw rod 404. A threaded hole adapted for the screw rod 404 is provided at the top of the side frame 401. The screw rod 404 is rotatably connected to the inside of the threaded hole. At the same time, the bottom is restricted by the lifting block 402. Therefore, when the screw rod 404 rotates, it can also drive the lifting block 402 to move up and down inside the side frame 401. A compression spring 403 is provided on the outer side of the screw rod 404. The upper side of the compression spring 403 abuts against the top inner wall of the side frame 401, and the lower side of the compression spring 403 abuts against the upper side of the lifting block 402. The top of the screw rod 404 extends to the side frame The upper side of 401 is fixedly connected with a handle 405; the conveying roller 406, the two ends of the upper conveying roller 406 are respectively fixedly installed between the two adjacent lifting blocks 402, and the two ends of the lower conveying roller 406 are respectively fixedly installed between the two adjacent side frames 401. The steel belt is transmitted from between the two conveying rollers 406 for conveying. The handle 405 is turned clockwise to drive the screw 404 to rotate and move upward inside the side frame 401. When the lifting block 402 moves with the screw 404, it can drive the upper conveying roller 406 to move synchronously, thereby increasing the distance between the two conveying rollers 406. Conversely, the distance between the two is reduced. In this way, steel belts of different thicknesses can be conveyed. An operation panel 5 is installed on the front side of the top of the body 1 for controlling the operation of all structures of the body 1.

[0033] The upper side of the body 1 is fixedly connected to the gantry 6, and the upper side of the body 1 is provided with an angle adjustment component 9, which is arranged inside the gantry 6. The angle adjustment component 9 includes: a shaft 11, which is installed on the upper side of the disc cutter 8, for driving the disc cutter 8 to rotate to achieve angle offset, the top of the shaft 11 is rotatably connected to the top inner wall of the gantry 6, and the bottom end of the shaft 11 extends to the lower side of the gantry 6; a connecting rod 904, one end of which is fixedly connected to the outer side of the shaft 11, and the other end of the connecting rod 904 is fixedly connected to the arc seat 907; a swing mechanism, which is located at the front side of the disc cutter 8, the swing mechanism includes a lever 901 for toggling the connecting rod 904, and the toggling rod 901 drives the shaft 11 to rotate through the connecting rod 904 during the swinging process; a rotating mechanism 7, which is arranged at the front bottom of the toggle rod 901, and the rotating mechanism 7 drives the toggle rod 901 to swing when it rotates.

[0034] A limiting groove is provided at the top of the shift lever 901, and a limiting ball 903 is slidably connected inside the limiting groove. The diameter of the limiting ball 903 is equal to the width of the limiting groove. The limiting ball 903 slides back and forth inside the limiting groove as the shift lever 901 swings. At the same time, when the shift lever 901 swings, relative rotation will also occur between the limiting ball 903 and the shift lever 901. The arc surface of the arc seat 907 fits tightly with the outer side of the limiting ball 903, and the two are slidably connected. By setting the limiting ball 903 and the arc seat 907, the angle between the shift lever 901 and the connecting rod 904 can be changed, thereby avoiding the situation where the connection angle between the two is fixed when the shift lever 901 swings, and the connecting rod 904 cannot rotate and cause interference.

[0035] A support rod 902 is fixedly connected to the middle of the rear side of the shifting rod 901. The shifting rod 901 swings around the support rod 902 with the support rod 902 as the axis point. The other end of the support rod 902 is rotatably connected to the front inner wall of the gantry 6.

[0036] A support plate 905 is provided at the bottom end of the connecting rod 904. The support plate 905 is a semicircular elastic sleeve. The connecting rod 904 is clamped inside the support plate 905. The bottom end of the support plate 905 is fixedly connected to a support block 906. The bottom end of the support block 906 is slidably connected to the inner wall of the gantry 6.

[0037] The rotating mechanism 7 includes: a turntable 702, which is arranged at the front side of the dial rod 901, and a fixed column 701 is fixedly connected to the rear side of the turntable 702. The fixed column 701 is located on the side of the turntable 702 away from the center. When the turntable 702 rotates, it can drive the fixed column 701 to make a circular motion. The fixed column 701 is slidably connected to the bottom of the dial rod 901. The bottom of the dial rod 901 is provided with a sliding groove adapted to the fixed column 701. When the turntable 702 rotates, it drives the fixed column 701 to move at the bottom of the dial rod 901, causing the bottom of the dial rod 901 to swing. While making a circular motion, the fixed column 701 can slide up and down in the sliding groove at the bottom of the dial rod 901; a locking member, which is located at the front side of the turntable 702. The outer sleeve of the locking member is provided with a shell 704. The shell The front side of 704 is connected to the rotation of the knob 705, and the front side of the shell 704 is provided with scale lines. The scale lines indicate the offset angle of the connecting rod 904. A pointer is provided on the knob 705 to indicate the scale lines on the shell 704. It can be calibrated before installation to ensure that the angle pointed by the knob 705 is equal to the offset angle of the connecting rod 904. The scale lines on the shell 704 are counted clockwise from 0 degrees to 60 degrees, then to 0 degrees, and then 60 degrees to the original 0 degrees. There are also multiple small scales evenly divided between each scale, which can be divided according to needs. When the pointer points to the left, it means that the connecting rod 904 is offset to the left. Similarly, when it points to the right, it is offset to the right. A locking member is provided to prevent the turntable 702 from rotating in the opposite direction.

[0038] The locking part includes: a ratchet 706, which is connected to the inside of the housing 704 and rotates parallel to the lever 901. An axial hole is opened inside the ratchet 706, and a pawl 707 is engaged on the outside of the ratchet 706. The characteristics of the ratchet 706 and the pawl 707 are used to play a locking function. The pawl 707 is used to clamp the ratchet 706, allowing the ratchet 706 to move in one direction and reversely lock the structural parts; a rotating rod 703, which is installed inside the housing 704 and fixedly sleeved in the axial hole. The two ends of the rotating rod 703 are respectively fixedly connected between the knob 705 and the turntable 702. Turning the knob 705 can drive the turntable 702 to rotate coaxially, and the fixed column 701 and the pointer on the knob 705 are in the same position.

[0039] A reciprocating mechanism 10 is provided at the top end of the disc cutter 8 for carrying the disc cutter 8 to move back and forth to cut the steel strip.

[0040] The reciprocating mechanism 10 includes a bidirectional screw rod 1002 installed at the top end of the disc cutter 8. The two threads opened on the outside of the bidirectional screw rod 1002 are opened at opposite angles and are connected at the head and tail to form a closed loop. The outer side of the bidirectional screw rod 1002 is provided with a movable sleeve 1003. The interior of the movable sleeve 1003 is provided with a guide block adapted to the thread, which is not drawn in detail in the figure. The guide block is slidably connected in the thread. Under the action of the guide block, when the bidirectional screw rod 1002 rotates, the disc cutter 8 can be driven to move through the movable sleeve 1003. The lower side of the movable sleeve 1003 is fixedly installed on the upper side of the disc cutter 8. When the bidirectional screw rod 1002 rotates, the disc cutter 8 can be driven to reciprocate through the movable sleeve 1003.

[0041] Both ends of the bidirectional screw rod 1002 are rotatably connected to a mounting bracket 1001 for mounting the disc cutter 8 , and the upper side of the mounting bracket 1001 is fixedly mounted on the lower side of the shaft 11 .

[0042] A cutting method for a cutting device used in a steel strip production line comprises the following steps: Step 1: Turn the knob 705 counterclockwise to rotate the turntable 702 via the rotating rod 703. The fixed column 701 will then rotate in a circular motion. Observe the position of the pointer on the knob 705 corresponding to the scale line on the indicator housing 704 to understand the rotation angle. Step 2: During the circular rotation of the fixed column 701, it slides on the bottom of the lever 901, and at the same time, an external force is applied to the bottom of the lever 901. Due to the restriction of the support rod 902, the bottom of the lever 901 swings to the left as the fixed column 701 rotates; Step 3: At this time, the top of the lever 901 will swing to the right. During the swinging process, it will drive the limiting ball 903 to slide on the top of the lever 901. The limiting ball 903 will only move horizontally and will not move up and down. The limiting ball 903 and the arc seat 907 will drive the connecting rod 904 to deviate to the right. At the same time, the shaft 11 will also rotate, so that the cutting angle of the disc cutter 8 can be adjusted through the mounting bracket 1001 at the bottom. Step 4: Observe the knob 705, adjust the required angle, stop turning the knob 705, and lock it with the locking member, then start the disc cutter 8 to perform the cutting operation.

[0043] In another embodiment provided by the present invention, a collection trough 12 is slidably connected to the top of the body 1, and the lower side of the collection trough 12 is slidably connected to the upper side of the body 1 for collecting cutting waste. The collection trough 12 is located on the lower side of the disc cutter 8, and the waste generated during cutting falls directly into the collection trough 12 to avoid being scattered on the body 1, making it easy to clean.

[0044] The front side of the collecting trough 12 is provided with an offset mechanism, which is connected to the angle adjustment assembly 9 through the offset mechanism. As the angle adjustment assembly 9 rotates, the collecting trough 12 is synchronously offset. The offset mechanism includes a connecting block 1201, the top of which is fixedly connected to the bottom end of the shift rod 901, and the bottom end of the connecting block 1201 is slidably connected to a connecting clip 1202, which is Y-shaped and has a retractable bottom design. In this way, when the shift rod 901 is offset and raised, the connecting clip 1202 can also be stretched by the connecting block 1201 to avoid affecting the rotation of the shift rod 901. The telescopic plate 1203 is located at the bottom of the gantry 6, and the upper front end of the telescopic plate 1203 is fixedly connected to the bottom end of the connecting clip 1202. The lower side of the telescopic plate 1203 is rotatably connected to a bottom shaft 1204 for supporting rotation. At the same time, the lower front end of the telescopic plate 1203 can also be slidably connected to the bottom shaft 1204, and the bottom end of the bottom shaft 1204 is fixedly connected to the upper side of the machine body 1.

[0045] The two sides of the collecting trough 12 are symmetrically fixedly connected with a ring 1206, and the inside of the ring 1206 is rotatably connected with a fixed shaft 1205, and the ring 1206 and the fixed shaft 1205 are detachable, and the bottom ends of the two fixed shafts 1205 are respectively fixedly connected to the telescopic plate 1203 and the upper side of the body 1. When the collecting trough 12 is full, the collecting trough 12 is held and lifted upward to separate the ring 1206 from the fixed shaft 1205, thereby pouring out the waste chips in the collecting trough 12. Under the action of the above structure, it is ensured that the collection trough 12 and the disc cutter 8 have the same offset angle.

[0046] In the above scheme, when the lever 901 is offset, one end of the telescopic plate 1203 is driven to offset through the connecting block 1201 and the connecting clamp 1202, and at the same time a thrust is given to the telescopic plate 1203. Under the action of the bottom shaft 1204, the telescopic plate 1203 is rotated and extended at the same time. The other end of the telescopic plate 1203 can drive the collecting trough 12 to offset through the fixed shaft 1205 and the ring 1206 on the front side, and the offset angle is the same as the offset angle of the upper disc cutter 8, and is always located below the cutting point of the steel strip, so as to facilitate the collection of waste chips generated during cutting.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
