Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of iron accessory processing, and specifically, to a cutting device for iron accessory production. Background Art

[0002] Iron accessories refer to parts made of iron materials for connecting, fixing, or assembling mechanical equipment. These parts can include bolts, nuts, studs, screws, bolt washers, nut washers, washers, pins, dowel pins, pin shafts, bearing seats, etc. Iron accessories play an important role in the process of mechanical manufacturing, connecting various components to ensure the normal operation of mechanical equipment. The mechanical manufacturing industry covers various companies and factories that produce mechanical equipment, including the manufacture of construction machinery, agricultural machinery, construction machinery, transportation equipment, power equipment, mining equipment, metallurgical equipment, etc. Among them, the production of bolts requires cutting after forging to obtain preliminary blanks.

[0003] In the prior art, the cutting device for iron accessory production is arranged near the cylindrical blank, and the motor is used to drive the full-disc cutter to rotate at high speed and cut the blank. It cooperates with the feeding mechanism of the cylindrical blank to realize the automation of the iron accessory blank cutting work. The cutting device for iron accessory production in the prior art has a low working efficiency. Each cutting can only produce one formed blank, and the cutting mechanism also needs to rotate at an angle along with the swing oil cylinder. In this way, not only the single production capacity of the equipment is wasted, but also the service life of the swing oil cylinder is reduced indirectly. Therefore, it is urgent to solve.

A protective cover is fixedly installed on the output shaft of the cutting motor. The first gear meshes with the sleeve, so that the cutting disc can make a circular motion around the axis of the support column; Fixing mechanism, the fixing mechanism includes a connecting column installed on the front of the cutting mechanism, one end of the connecting column is fixedly connected with a follower ring, a magnet is movably sleeved on the inner side of the outer surface of the follower ring, a damping ring is fixedly installed on the outer side of the outer surface of the follower ring, and the back of the damping ring abuts against the front end of the workpiece; The feeding mechanism is arranged in four groups, and each group of the feeding mechanism holds and installs a group of workpieces, and the cutting disc can completely cover a certain group of workpieces.

[0006] Preferably, the feeding mechanism includes a fixed column, a first support cylinder and a second support cylinder fixedly installed on the outer peripheral surface of the bracket. The second support cylinder, the fixed column and the first support cylinder are arranged in sequence from front to back. There are two groups of fixed columns. One end of the fixed column is fixedly installed with a mounting frame. Two groups of rollers are rotatably installed on the inner wall of the mounting frame. A feeding motor is installed on the side of one group of mounting frames. The feeding motor drives the rollers to rotate. The workpiece is clamped and installed inside the second support cylinder, the first support cylinder and the rollers. A feeder is fixedly installed at the rear end of the first support cylinder, and the feeder is designed in a flared shape.

[0007] Preferably, the damping ring is made of a non-metallic material with a high friction coefficient. There is a gap between the back of the magnet and the front of the damping ring. The shape of the magnet is fan-shaped, and the magnet faces the front of the cutting disc.

[0008] Preferably, a first connecting block is fixedly installed between the driving motor and the outer surface of the support column, and the first connecting block is located at the front side of the inner cavity of the box.

[0009] Preferably, the diameter value of the first gear is smaller than the diameter value of the second gear, and there is a clearance fit between the inner wall of the second gear and the outer surface of the support column.

[0010] Preferably, a protective cover is arranged on the outer surface of the cutting disc. The protective cover is fixedly connected with the cutting motor, and the output shaft of the cutting motor is rotatably installed on the surface of the protective cover.

[0011] Preferably, there is an interference fit between the workpiece and the inner walls of the first support cylinder and the second support cylinder, and the friction force between the roller and the outer surface of the workpiece is greater than the friction force between the workpiece and the inner walls of the first support cylinder and the second support cylinder.

[0012] Preferably, the rotation direction of the cutting disc is opposite to the direction of the cutting disc revolving around the axis of the support column, and the protective cover cannot contact the workpiece.

[0013] Preferably, the feeding motor is a servo motor. There are four groups of feeding motors, which are circumferentially and equidistantly distributed in the four groups of feeding mechanisms. The feeding motor is installed on the back of the last group of mounting frames.

[0014] Preferably, when the cutting motor is driven to rotate around the axis of the support column, the outer surface of the cutting motor is separated from the gear one.

[0015] The beneficial effects of the embodiments of the present disclosure are: 1. The device has been redesigned to use a driving motor to drive gear one and gear two to rotate, driving the cutting disc to revolve around the axis of the support column, abandoning the use of an oil cylinder to swing the cutting disc in the prior art, avoiding wasting the cutting stroke of the cutting disc being driven back and reset by the swinging oil cylinder. The device is provided with four groups of feeding mechanisms located on the outer peripheral surface of the box body to fix and clamp the four groups of workpieces around the box body. At the same time, a support column is provided in the middle of the box body to rotationally support the sleeve, gear two, cutting motor and cutting disc, and the transmission is carried out through gear one and gear two, so that the cutting disc moves in a circle around the support column under the drive of the driving motor, and the four groups of workpieces are just located in the coverage area of ​​the cutting disc revolution. In this way, the high-speed rotating cutting disc can perform cyclic cutting on the four groups of workpieces, effectively improving the working efficiency of the device, so that the cutting disc does not need to be reset when being driven to prepare for the next cutting.

[0016] 2. The device is also provided with a fixing mechanism located in front of the cutting mechanism, which assists the cutting mechanism in fixing the workpiece before cutting. The friction force is generated between the connecting column and the damping ring and the workpiece, so that the damping ring is fixed relative to the follower ring. When the cutting motor and the protective cover move under the drive of the driving motor, the follower ring and the magnet will be driven to rotate. At this time, the magnets relative to the front and back of the cutting disk move simultaneously. When the cutting disk is to cut a group of workpieces, the magnet covering the end of the workpiece can magnetically fix the cut part of the front end of the workpiece, so that the front end of the workpiece will not fall off temporarily when it is completely cut off by the cutting disk, but wait for the cutting disk to continue to revolve around the axis of the support column to the surface of the next group of workpieces, and the magnet will be separated from the covering position of the cut workpiece, so that the cut workpiece loses its magnetic attraction and finally falls off. This design not only enhances the fixing stability of the workpiece when it is cut, but also enables the cut workpiece to be staggered with the high-speed rotating cutting disk, so as to avoid the workpiece being cut and falling near the cutting disk, thereby protecting the cut workpiece.

[0017] 3. The device can also drive the cutting disc to revolve through the driving motor, thereby reducing the wear of the cutting disc. First, the cutting disc rotates at high speed under the drive of the cutting motor, and then the cutting disc revolves around the axis of the support column. Each time the cutting disc reaches a cutting position for a group of workpieces, the contact point with the outer surface of the workpiece is different. After one cycle of revolution, the outer surface of the cutting disc will not maintain a contact position every time it contacts the workpiece, thereby effectively reducing the overall wear of the cutting disc, extending the service life of the cutting disc, and improving safety.

[0027] As Figures 1 to 8 shown, the present invention discloses a cutting device for the production of iron accessories, including: a bracket 1, on the top of the bracket 1 is installed a box body 2, and multiple feeding mechanisms 4 are arranged on the outer peripheral surface of the box body 2; Cutting mechanism 5, the cutting mechanism 5 is installed inside the box body 2. The cutting mechanism 5 includes a driving motor 51 fixedly installed on the inner wall of the box body 2 and a support column 54. The output shaft of the driving motor 51 and the support column 54 both penetrate to the front of the box body 2. A first gear 53 is fixedly installed on the output shaft of the driving motor 51. A sleeve 55 is rotatably installed at the front end of the support column 54. A second gear 56 is fixedly installed at the rear end of the sleeve 55. A second connecting block 57 is fixedly installed on the outer surface of the sleeve 55. One side of the second connecting block 57 is fixedly connected to a cutting motor 58. A protective cover 510 is fixedly installed on the output shaft of the cutting motor 58. The first gear 53 meshes with the sleeve 55, enabling the cutting disc 59 to perform a circular motion around the axis of the support column 54; Fixing mechanism 6, the fixing mechanism 6 includes a connecting column 61 installed on the front of the cutting mechanism 5. One end of the connecting column 61 is fixedly connected to a follower ring 62. A magnet 63 is movably sleeved on the inner side of the outer surface of the follower ring 62. A damping ring 64 is fixedly installed on the outer side of the outer surface of the follower ring 62. The back of the damping ring 64 abuts against the front end of the workpiece 3; The feeding mechanism 4 is provided in four groups. Each group of the feeding mechanism 4 holds and installs a group of workpieces 3. The cutting disc 59 can completely cover a certain group of workpieces 3; This device has been redesigned. The driving motor 51 drives the first gear 53 and the second gear 56 to rotate, driving the cutting disc 59 to revolve around the axis of the support column 54, abandoning the use of an oil cylinder to swing the cutting disc 59 in the prior art, avoiding wasting the cutting stroke of the cutting disc 59 when it is driven back by the swinging oil cylinder to reset. This device is provided with four groups of feeding mechanisms 4 on the outer peripheral surface of the box body 2, fixedly clamping the four groups of workpieces 3 around the box body 2. At the same time, by providing a support column 54 in the middle of the box body 2, rotational support is provided for the sleeve 55, the second gear 56, the cutting motor 58, and the cutting disc 59. Through the transmission of the first gear 53 and the second gear 56, the cutting disc 59 makes a circular motion around the support column 54 under the drive of the driving motor 51, and the four groups of workpieces 3 are just located in the coverage area of the revolution of the cutting disc 59. In this way, the cutting disc 59 rotating at high speed can circularly cut the four groups of workpieces 3, effectively improving the working efficiency of the device, and enabling the cutting disc 59 not to need to reset when being driven and then prepare for the next cutting.

[0028] Embodiment 2: The feeding mechanism 4 includes a fixed column 44, a first support cylinder 41, and a second support cylinder 43 that are fixedly installed on the outer peripheral surface of the bracket 1. The second support cylinder 43, the fixed column 44, and the first support cylinder 41 are arranged in sequence from front to back. There are two groups of fixed columns 44. One end of the fixed column 44 is fixedly installed with a mounting frame 45. Two groups of rollers 46 are rotatably installed on the inner wall of the mounting frame 45. A feeding motor 47 is installed on the side of one group of mounting frames 45. The feeding motor 47 drives the rollers 46 to rotate. The workpiece 3 is clamped and installed inside the second support cylinder 43, the first support cylinder 41, and the rollers 46. A material guide 42 is fixedly installed at the rear end of the first support cylinder 41. The material guide 42 is designed with a flared opening; The large flared opening design of the material guide 42 enables the workpiece 3 to be more easily aligned with the inside of the first support cylinder 41, facilitating the feeding of the workpiece 3, thereby effectively improving the working efficiency of the device; Four groups of feeding mechanisms 4 are installed on the outer peripheral surface of the box body 2 of this device. Four groups of workpieces 3 are fed and fixed through the four groups of feeding mechanisms 4. The workpiece 3 is supported by the second support cylinder 43 and the first support cylinder 41 arranged one in front and one behind. At the same time, the two groups of mounting frames 45 and rollers 46 located in the middle are used to drive the workpiece 3 to move forward. Among them, a feeding motor 47 is installed on the rear mounting frame 45. The feeding motor 47 drives the rollers 46 to rotate. Under the rotational contact friction force between the rollers 46 and the workpiece 3, the workpiece 3 is driven to feed forward. By utilizing the static friction force generated by the interference fit between the second support cylinder 43 and the first support cylinder 41 and the outer surface of the workpiece 3 and the large contact area of the long cylindrical shape of the first support cylinder 41 and the second support cylinder 43, the device does not require a specific fixing mechanism to fix the workpiece 3, thus eliminating the preparation steps during cutting. It only needs to ensure that the friction force between the rollers 46 and the workpiece 3 is greater than the friction force between the first support cylinder 41, the second support cylinder 43, and the workpiece 3.

[0029] Embodiment 3: The damping ring 64 is made of a non-metallic material with a high coefficient of friction. There is a gap between the back surface of the magnet 63 and the front surface of the damping ring 64. The shape of the magnet 63 is fan-shaped, and the magnet 63 faces the front surface of the cutting disc 59; The damping ring 64 is made of ceramic or synthetic rubber. When the workpiece 3 is driven forward by the feeding mechanism 4, by applying pressure to the workpiece 3 and making the front end of the workpiece 3 abut against the back surface of the damping ring 64 to generate static friction force. When the magnet 63 moves to cover the front end of the workpiece 3, it will generate a magnetic attraction force on the workpiece 3, making the pressure between the front end of the workpiece 3 and the damping ring 64 greater, that is, the static friction force is greater, so as to realize the auxiliary fixing function of the workpiece 3 during cutting; The device is also provided with a fixing mechanism 6 located in front of the cutting mechanism 5, which assists the cutting mechanism 5 in fixing the workpiece 3 before cutting, and generates friction with the workpiece 3 through the connecting column 61 and the damping ring 64, so that the damping ring 64 is fixed relative to the follower ring 62. When the cutting motor 58 and the protective cover 510 are driven by the driving motor 51 to move, the follower ring 62 and the magnet 63 are driven to rotate. At this time, the magnet 63 opposite to the front and rear of the cutting disk 59 moves at the same time. When the cutting disk 59 is about to cut a group of workpieces 3, the magnet 63 covering the end of the workpiece 3 can be cut at the front end of the workpiece 3. The cut part is fixed by magnetic attraction, so that the front end of the workpiece 3 will not fall off temporarily when it is completely cut off by the cutting disk 59, but waits for the cutting disk 59 to continue to revolve around the axis of the support column 54 to the surface of the next group of workpieces 3, and the magnet 63 is separated from the covering position of the cut workpiece 3, so that the cut workpiece 3 loses its magnetic attraction and finally falls off. This design not only enhances the fixing stability of the workpiece 3 when being cut, but also enables the cut workpiece 3 to be staggered with the high-speed rotating cutting disk 59, thereby preventing the workpiece 3 from being cut and falling near the cutting disk 59, thereby protecting the cut workpiece 3.

[0030] Embodiment 4: A connecting block 1 52 is fixedly installed between the driving motor 51 and the outer surface of the supporting column 54, and the connecting block 1 52 is located at the front side of the inner cavity of the box body 2; The connecting block 52 is used to fix the connection between the driving motor 51 and the support column 54. On the front side of the inner cavity of the box body 2, the driving motor 51 and the support column 54 are fixedly installed on the inner wall of the box body 2. The setting of the connecting block 52 can maintain the stability of the driving motor 51 and the support column 54.

[0031] Embodiment 5: The diameter of the gear 1 53 is smaller than the diameter of the gear 2 56 , and there is a clearance fit between the inner wall of the gear 2 56 and the outer surface of the support column 54 ; The output torque of the driving motor 51 can be amplified under the transmission action of gear 1 53 and gear 2 56 , while reducing the revolution speed of the cutting disc 59 . Gear 2 56 is not connected to the support column 54 , thereby ensuring the smooth rotation of the connecting block 2 57 and gear 2 56 .

[0032] Embodiment 6: A protective cover 510 is provided on the outer surface of the cutting disc 59, the protective cover 510 is fixedly connected to the cutting motor 58, and the output shaft of the cutting motor 58 is rotatably mounted on the surface of the protective cover 510; The protective cover 510 is located on the outside of the cutting disc 59, which can provide protection for the cutting disc 59 and prevent the cutting disc 59 from being broken and splashing outward due to high-speed rotation, thereby creating a safety hazard.

[0033] Embodiment 7: There is an interference fit between the workpiece 3 and the inner walls of the first support cylinder 41 and the second support cylinder 43, and the frictional force between the roller 46 and the outer surface of the workpiece 3 is greater than the frictional force between the workpiece 3 and the inner walls of the first support cylinder 41 and the second support cylinder 43; The feeding motor 47 drives the roller 46 to rotate. Under the action of the rotational contact frictional force between the roller 46 and the workpiece 3, the workpiece 3 is driven to feed forward. By using the static frictional force generated by the interference fit between the outer surface of the workpiece 3 and the second support cylinder 43 and the first support cylinder 41, and the cooperation of the large contact area of the long cylindrical shapes of the first support cylinder 41 and the second support cylinder 43, the device does not require a specific fixing mechanism to fix the workpiece 3.

[0034] Embodiment 8: The self-rotation direction of the cutting disc 59 is opposite to the direction of the revolution of the cutting disc 59 around the axis of the support column 54, and the protective cover 510 cannot contact the workpiece 3; The device can also drive the cutting disc 59 to revolve through the driving motor 51, thereby reducing the wear degree of the cutting disc 59. First, the cutting disc 59 rotates at a high speed under the drive of the cutting motor 58. Then, the cutting disc 59 revolves around the axis of the support column 54. Every time the cutting disc 59 reaches the cutting position of a group of workpieces 3, the contact points between it and the outer surface of the workpiece 3 are different. After a cycle of one revolution, the outer surface of the cutting disc 59 will not maintain a contact position every time it contacts the workpiece 3, thereby effectively reducing the overall wear degree of the cutting disc 59, extending the service life of the cutting disc 59, and improving safety.

[0035] Embodiment 9: The feeding motor 47 is a servo motor. Four sets of feeding motors 47 are provided and are circumferentially and equidistantly distributed in the four sets of feeding mechanisms 4. The feeding motor 47 is installed on the back of the rear set of mounting brackets 45; Each set of feeding mechanisms 4 is provided with a set of feeding motors 47, which are used to drive the roller 46 to rotate and push the workpiece 3 forward to achieve feeding.

[0036] Embodiment 10: When the cutting motor 58 is driven to rotate around the axis of the support column 54, the outer surface of the cutting motor 58 is separated from the first gear 53; The outer surfaces of the cutting motor 58 and the first gear 53 are in a separated movement, so that the cutting motor 58 will not touch the first gear 53 during revolution, avoiding jamming and damage.

[0037] Working principle: When the device is working, the workpiece 3 is inserted into the first support cylinder 41 along the feeder 42, and the workpiece 3 is continuously pushed forward so that the workpiece 3 abuts against the roller 46. The feeding motor 47 is started to drive the roller 46 to rotate, and the workpiece 3 is driven forward so that the front end of the workpiece 3 protrudes from the front end of the second support cylinder 43. In the initial state, the cutting disc 59 is located at the middle position between two adjacent groups of workpieces 3; Then, start the cutting motor 58 to drive the cutting disc 59 to rotate at high speed. At this time, all four groups of workpieces 3 protrude forward and are fixed in place. The friction force provided by the second support cylinder 43, the first support cylinder 41, and the roller 46 to the workpiece 3 provides the fixation of the workpiece 3. Start the driving motor 51, and drive the first gear 53, the second gear 56, and the sleeve 55 to rotate. The sleeve 55 drives the cutting motor 58 and the cutting disc 59 to revolve around the axis of the support column 54 through the second connecting block 57. During the revolution process, the cutting disc 59 will come into contact with the four groups of workpieces 3 in sequence, so as to cut off the protruding part of the workpiece 3, generate a formed blank, and automatically fall under the action of gravity. When the cutting disc 59 finishes cutting one group of workpieces 3 and rotates to the next group of workpieces 3, the feeding mechanism 4 corresponding to the cut group of workpieces 3 can be driven by the feeding motor 47 for a specified distance and protrude forward to complete the preparation for the next cutting. In this way, the driving motor 51 can continuously drive the cutting disc 59 to revolve, and cooperate with the rotation of the cutting disc 59 to circularly cut the four groups of workpieces 3 to achieve the purpose of efficient cutting; When the workpiece 3 is driven forward by the feeding mechanism 4, by applying pressure to the workpiece 3 and making the front end of the workpiece 3 abut against the back surface of the damping ring 64 to generate static friction force. When the magnet 63 moves to cover the front end of the workpiece 3, it will generate a magnetic attraction force on the workpiece 3, making the pressure between the front end of the workpiece 3 and the damping ring 64 greater, that is, the static friction force is greater, so as to realize the auxiliary fixation function of the workpiece 3 during cutting.
