Description

Technical Field

[0001] The present invention belongs to the technical field of bolt cutting and processing, and specifically relates to a cutting device for bolt production. Background Art

[0002] A bolt is a common fastener that connects two or more components by cooperating with a nut or directly screwing into a hole with internal threads. The production and processing of bolts are usually made by processing a bar through steps such as cutting, upsetting, and turning. When cutting the bar, the bar is usually cut according to the model of the bolts to be produced.

[0003] A patent with the publication number CN119368811B discloses a cutting device for bolt production. The device supports the right side of the bar cutting position by setting two support plates. Before the bar moves to the corresponding position of the cutting device, the support plates are located below the right side of the bar. Thus, when the bar is conveyed to the corresponding position of the cutting device, the two support plates do not block the end of the bar, enabling the cutting position of the bar to move to the corresponding position of the cutting device, increasing the cutting efficiency of the bar. By setting a positioning plate and a triangular plate to position the right end of the bar, and the distance between the positioning plate and the triangular plate and the cutting device can be adjusted. When the two support plates move to the left and support the right side of the bar cutting position, the positioning plate and the triangular plate can abut against the right end of the bar. Thus, the cutting position of the bar can be accurately adjusted according to the distance between the positioning plate and the triangular plate and the cutting device, increasing the cutting accuracy of the bar.

[0004] The above solution still has some problems in actual application. Usually, the bar stock is placed on the cutting table, and the bar stock is pushed while adjusting the cutting position, and then the cutting device is driven to cut the bar stock. After cutting, the cut bolt blanks are collected, and then the bar stock is pushed again to adjust the cutting position for cutting. However, the existing cutting method is basically a vertical or horizontal movement cutting point by point, which not only has a large resistance during cutting and low cutting efficiency, but also the cutting blade is prone to overload damage, and subsequently, a grinding device needs to be used separately to grind the cut surface of the bolt blank, greatly affecting the bolt production efficiency.

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0023] Example 1: As Figures 1 to 8 shown, a cutting device for bolt production according to an embodiment of the present invention includes a base 1. On one side of the upper end surface of the base 1, a conveying roller path 2 is provided. Inside the conveying roller path 2, a bar stock conveying component 3 is installed for conveying the bar stock 10 according to the length of the produced bolts. On one side of the upper end surface of the base 1, a recycling through groove 4 is provided. Inside the recycling through groove 4, a cutting and grinding component 5 is provided; And the cutting and grinding component 5 includes four gears 52 installed on the inner wall of the recycling through groove 4. Among them, the four gears 52 are grouped in pairs and symmetrically arranged. The gears 52 are meshed with two toothed rings 51, and the two toothed rings 51 are connected in series and fixed. Between the two toothed rings 51, three servo push rods 55 are installed. The piston rod end of one servo push rod 55 is installed with a disc blade 54, and the piston rod ends of the other two servo push rods 55 are fixedly connected with grinding sheets 57 for grinding the cut part of the bar stock 10; The bar stock conveying component 3 includes a plurality of conveying rollers 31 rotatably connected inside the conveying roller path 2. The conveying rollers 31 are arranged in a semi-circular shape with an inner concave and outer convex shape, and rubber anti-slip tooth blocks are arranged in a ring shape on the outside of the conveying rollers 31, so that the bar stock 10 can be conveyed in the middle of the conveying rollers 31.

[0024] Specifically, in the prior art, the bar stock is usually placed on the cutting table, and at the same time, the bar stock is pushed to adjust the cutting position, and then the cutting device is driven to cut the bar stock. After cutting, the cut bolt blanks are collected, and then the bar stock is pushed again to adjust the cutting position for cutting processing. However, the existing cutting methods are basically vertical or horizontal movement cutting point-to-point, which not only has a large resistance during cutting and low cutting efficiency, but also the cutting blades are easily damaged, and subsequently, a separate grinding device is required to grind the cut part of the bolt blanks, which greatly affects the bolt production efficiency; In the present invention, the bar stock 10 is placed in the conveying roller path 2, and at the same time, the conveying roller 31 is driven to rotate. The conveying roller 31 is arranged in a semi-circular shape with an inner concave and outer convex structure, and is externally provided with rubber anti-slip teeth in a circular shape. Thus, the bar stock 10 can be stably conveyed to the cutting and grinding assembly 5. The inner concave and outer convex setting of the conveying roller 31 enables the bar stock 10 to always be in the middle of the conveying roller 31, avoiding the left and right movement of the bar stock 10 from affecting the cutting accuracy. After the cutting position of the bar stock 10 is adjusted during conveying, by driving the gear 52 to rotate and making the gear 52 meshingly drive the ring gear 51 to rotate, at the same time, the ring gear 51 drives the servo push rod 55 to rotate synchronously. During the rotation of the ring gear 51, by starting the servo push rod 55 to drive the disc blade 54 close to the bar stock 10 and at the same time starting the disc blade 54 to operate, thus, during the process of the ring gear 51 driving the servo push rod 55 to rotate, the disc blade 54 can cut around the bar stock 10 in a circular shape. Compared with the existing method of using a disc blade to perform linear cutting from top to bottom or from bottom to top, not only is the resistance small, but also the flatness of the cut can be ensured. Then, by driving the grinding disc 57 to move with the servo push rod 55 and making the grinding disc 57 insert into the cutting opening of the bar stock 10, and then during the rotation of the ring gear 51, driving the servo push rod 55 to rotate, at the same time, the servo push rod 55 drives the grinding disc 57 to rotate synchronously. Thus, the cutting opening of the bar stock 10 can be ground by the grinding disc 57. The disc blade 54 cuts around the bar stock 10 in a circular shape, which can reduce the unevenness of the cut opening of the bar stock 10, and then the grinding disc 57 can more quickly perform grinding treatment on the cut opening, facilitating the quality during the later bolt processing and manufacturing, thereby solving the above problems.

[0025] As Figure 1 , Figure 2 and Figure 5 shown, a transmission groove 32 is opened inside one end of the base 1. A rotating shaft 35 is rotatably connected inside the cavity of the transmission groove 32. A plurality of driven bevel gears 34 are fixedly connected to the outside of the rotating shaft 35, and the plurality of driven bevel gears 34 are meshingly connected with a first bevel gear 33, and the first bevel gear 33 is fixedly connected to the conveying roller 31.

[0026] As Figure 1 , Figure 2 and Figure 5 shown, a servo motor 11 is installed at one end of the base 1. A transmission bevel gear 36 is fixedly connected to the output shaft end of the servo motor 11 and is located inside the cavity of the transmission groove 32. The transmission bevel gear 36 is meshingly connected with the driven bevel gear 34 for driving the conveying roller 31 to drive the bar stock 10 for conveying.

[0027] Specifically, when transporting the bar stock 10 to produce bolt blanks, the servo motor 11 is started to drive the driving bevel gear 36 to rotate, and the driving bevel gear 36 meshes with and drives the driven bevel gear 34 to rotate, thereby driving the rotating shaft 35 to rotate. During the rotation of the rotating shaft 35, the driven bevel gear 34 will be driven to rotate synchronously. At the same time, the driven bevel gear 34 meshes with and drives the first bevel gear 33 to rotate, thereby driving the conveying roller 31 to rotate. Thus, the bar stock 10 can be transported and moved according to the cutting requirements, improving the automation degree of the cutting equipment and increasing the processing efficiency of bolt blanks.

[0028] As Figures 1 to 2 shown, four T-shaped support columns 12 are installed at the upper end of the base 1, and the four T-shaped support columns 12 are grouped in pairs and symmetrically arranged. Each T-shaped support column 12 is slidably connected with a T-shaped mounting block 13 on the outside. A tension spring 14 is fixedly connected to the lower end of the T-shaped mounting block 13, and one end of the tension spring 14 is fixedly connected to the base 1. A bar stock limiting component 9 is installed between the T-shaped mounting blocks 13, which is used to pull the bar stock limiting component 9 to press the bar stock 10, and can improve the stability of the bar stock 10 during transportation.

[0029] Specifically, when transporting and cutting the bar stock 10, the tension spring 14 is used to pull the T-shaped mounting block 13 to slide downward outside the T-shaped support column 12, and the T-shaped mounting block 13 drives the bar stock limiting component 9 to move downward synchronously. Then, the bar stock limiting component 9 is used to press and limit the bar stock 10. At the same time, the conveying roller 31 is used to convey the bar stock 10. Moreover, the bar stock limiting component 9 and the conveying roller 31 can clamp the bar stock 10. At the same time, by using the limiting effect of the bar stock limiting component 9, it is ensured that the bar stock 10 will not move or shake during the cutting process, improving the cutting accuracy of the bar stock 10. This solves the problem that in the existing cutting equipment for bolt production, when cutting the bar stock to process bolt blanks, usually a clamping component is used to clamp and fix the bar stock, and then the cutting component is controlled to cut the bar stock. After cutting, the clamping component needs to be loosened to adjust the position of the conveyed bar stock, and then the bar stock is cut again to process bolt blanks. This not only has cumbersome operations but also affects the processing efficiency of bolt blanks.

[0030] As Figure 1 、 Figure 3 and Figure 4 shown, the bar stock limiting component 9 includes a support frame 91 installed between the T-shaped mounting blocks 13. A plurality of rotating columns 92 are rotatably connected to the inner cavity of the support frame 91. Each rotating column 92 is provided with a chute 93 inside. Two limiting sliding disks 94 are slidably connected to the inner cavity of the chute 93, and the mutually approaching surfaces of the limiting sliding disks 94 are arranged in a semi-circular arc shape, which is used to clamp bar stocks 10 with different diameters and limit the position of the bar stock 10.

[0031] As Figure 1 、Figure 3 and Figure 4 As shown in Figure 4 , two fixed disks 96 are installed outside the rotating column 92. One end of the limit sliding disk 94 is installed with a second spring 95, and one end of the second spring 95 abuts against the support frame 91.

[0032] Specifically, when the bar stock 10 is conveyed and cut, the tension spring 14 is used to pull the T-shaped mounting block 13 to drive the support frame 91 to move downward, and the support frame 91 drives the rotating column 92 to move downward. Then, the rotating column 92 is used to press the bar stock 10 to ensure the stability of the bar stock 10 during conveyance. Moreover, when the bar stock 10 is pressed, the second spring 95 is used to bounce the limit sliding disks 94 to move closer to each other. The mutually approaching surfaces of the limit sliding disks 94 are arranged in a semi-circular arc shape. Therefore, during the process of the support frame 91 driving the rotating column 92 to move downward, the two limit sliding disks 94 are used to further clamp and limit the bar stock 10, so as to improve the stability of the bar stock 10 during conveyance and cutting, and avoid the situation that the bar stock 10 is offset during conveyance and cutting, which affects the cutting accuracy. Thus, it solves the problem that in the existing cutting equipment for bolt production, when cutting the bar stock into bolt blanks, due to the inconvenience of clamping and limiting bar stocks of different thicknesses, the cutting equipment cannot be applied to the processing of bolts of different sizes.

[0033] Embodiment 2: As shown in Figure 2 、 Figure 5 and Figure 8 As shown in Figure 8 , a cutting length adjustment component 6 is installed on one side of the upper end surface of the base 1. The cutting length adjustment component 6 includes two grooves 61 opened on one side of the upper end surface of the base 1. A threaded rod 62 is rotatably connected to the inner cavity of the groove 61. A U-shaped sliding frame 63 is threadedly connected to the outside of the threaded rod 62. A scale groove 8 is opened on the upper end surface of the base 1 on one side of the groove 61, which is used to drive the position of the U-shaped sliding frame 63 in the inner cavity of the groove 61, and the conveyance of the bar stock 10 can be blocked by the U-shaped sliding frame 63.

[0034] Specifically, when cutting the bar stock 10, the threaded rod 62 is driven to rotate, and the threaded rod 62 threadedly drives the U-shaped sliding frame 63 to slide in the inner cavity of the groove 61. At the same time, the scale groove 8 penetrates through the position where the U-shaped sliding frame 63 moves. Then, the bar stock conveying assembly 3 is used to convey the bar stock 10 for feeding. Then, the bar stock 10 is abutted against the U-shaped sliding frame 63. The distance from the cutting and grinding assembly 5 to the U-shaped sliding frame 63 is the length of the bolt blank. Therefore, when cutting and processing the bolt blanks in the same batch, there is no need to adjust the position of the U-shaped sliding frame 63. After the bar stock 10 is cut by the cutting and grinding assembly 5, the bar stock conveying assembly 3 automatically conveys the bar stock 10. After the bar stock 10 is abutted against the U-shaped sliding frame 63, the cutting and grinding assembly 5 is driven to cut the bar stock 10, thereby realizing the cyclic cutting and processing of the bolt blanks, improving the production efficiency of the bolts, and solving the problem that in the existing cutting equipment for bolt production, when cutting the bar stock to process the bolt blanks, after each cutting of the bar stock is completed, it is necessary to measure the cutting position of the bar stock to ensure that the length of the bolt blank meets the standard, which is not only cumbersome to operate but also affects the production and processing efficiency of the bolt blanks.

[0035] As Figure 1 , Figure 6 and Figure 7 shown, a chute 56 is provided at one end of the grinding disc 57. A slider 59 is slidably connected in the inner cavity of the chute 56. One end of the slider 59 is fixedly connected with a stopper 510, and one end of the stopper 510 is arranged in a semicircular arc shape.

[0036] As Figure 1 , Figure 6 and Figure 7 shown, a sliding column 511 is fixedly connected in the inner cavity of the chute 56. The slider 59 is slidably connected with the sliding column 511. One end of the slider 59 is fixedly connected with a first spring 58. One end of the first spring 58 is fixedly connected with the inner wall of the chute 56. Four limiting pulleys 53 are rotatably connected to the inner wall of the recovery through groove 4. The four limiting pulleys 53 are divided into two groups in pairs and are symmetrically arranged to assist the rotation of the gear ring 51.

[0037] Specifically, when cutting the bar stock 10, the bar stock conveying assembly 3 conveys the bar stock 10 into the inner cavity of the gear ring 51. Then, the servo push rod 55 is used to drive the disc blade 54 close to the bar stock 10, and the motor drives the disc blade 54 to cut the bar stock 10. At the same time, it cooperates with the rotation of the gear ring 51 to rotate around the bar stock 10 in a circular motion for cutting. When the gear ring 51 drives the grinding disc 57 to move to the cutting opening of the bar stock 10, the servo push rod 55 is used to drive the grinding disc 57, and the grinding disc 57 is inserted into the cut of the bar stock 10. At the same time, with the rotation of the gear ring 51, the grinding disc 57 rotates synchronously to polish the cutting opening of the bar stock 10. At the same time, the first spring 58 is used to bounce up the slider 59, and the slider 59 drives the abutting block 510 to slide outside the sliding column 511 to polish one end corner of the bar stock 10, avoiding the trouble of separately polishing the cut of the bolt blank when the bolt is machined by turning the bolt blank later, and improving the cutting efficiency of the bolt blank.

[0038] As Figure 1 , Figure 2 and Figure 8 shown, a recycling guiding assembly 7 is arranged inside one side of the upper end surface of the base 1, and the recycling guiding assembly 7 includes a flipping opening 71 opened on one side of the upper end surface of the base 1. Two rotating grooves 72 are opened on the inner wall of the flipping opening 71. A flipping plate 73 is rotatably connected inside the flipping opening 71. A rotating disc 74 is fixedly connected outside the inner cavity of the rotating groove 72 of the flipping plate 73. A torsion spring 75 is fixedly connected to one side of the rotating disc 74, and one end of the torsion spring 75 is fixedly connected to the inner wall of the rotating groove 72.

[0039] Specifically, after cutting the bolt blank from the bar stock 10, the weight of the bolt blank is used to drive the flipping plate 73 to flip. At the same time, the flipping plate 73 drives the rotating disc 74 to flip, so that the rotating disc 74 twists the torsion spring 75 to flip downward, so that the bolt blank slides out of the base 1 along the inclined flipping plate 73 for collection. Then, the torsion spring 75 twists the rotating disc 74 to rotate, and the rotating disc 74 drives the flipping plate 73 to rotate back to its original position, so as to wait for receiving the next bolt blank, solving the problem that after the existing cutting equipment for bolt production cuts the bar stock, since the operator needs to collect the cut bolt blank and then push the bar stock to cut the next bolt blank, the operation is cumbersome and affects the cutting efficiency of the bolt blank.

[0040] Working principle: Place the bar stock 10 in the conveying roller path 2, and at the same time drive the conveying roller 31 to rotate. The conveying roller 31 is arranged in a semi-circular shape with an inner concave and outer convex structure, and rubber anti-slip teeth are arranged in a ring shape on the outside. Thus, the bar stock 10 can be stably conveyed towards the cutting and grinding assembly 5. The inner concave and outer convex setting of the conveying roller 31 enables the bar stock 10 to always be in the middle of the conveying roller 31, avoiding the left and right movement of the bar stock 10 from affecting the cutting accuracy. After the cutting position of the bar stock 10 is adjusted during conveying, drive the gear 52 to rotate, and make the gear 52 meshingly drive the toothed ring 51 to rotate. At the same time, the toothed ring 51 drives the servo push rod 55 to rotate synchronously. During the rotation of the toothed ring 51, start the servo push rod 55 to drive the disc blade 54 close to the bar stock 10, and at the same time start the disc blade 54 to operate. Thus, during the process of the toothed ring 51 driving the servo push rod 55 to rotate, the disc blade 54 can cut around the bar stock 10 in a ring shape. Compared with the existing method of using a disc blade to perform linear cutting from top to bottom or from bottom to top, not only is the resistance small, but also the flatness of the cut can be ensured. Then, drive the grinding disc 57 to move through the servo push rod 55, and make the grinding disc 57 insert into the cut of the bar stock 10. Then, during the rotation of the toothed ring 51, drive the servo push rod 55 to rotate, and at the same time the servo push rod 55 drives the grinding disc 57 to rotate synchronously. Thus, the cut of the bar stock 10 can be ground by the grinding disc 57. The disc blade 54 cuts around the bar stock 10 in a ring shape, which can reduce the unevenness of the cut of the bar stock 10. Then, the grinding disc 57 can be used to grind the cut more quickly, so as to facilitate the quality during the later bolt processing and manufacturing; When conveying and cutting the bar stock 10, use the tension spring 14 to pull the T-shaped mounting block 13 to drive the support frame 91 to move downward, and make the support frame 91 drive the rotating column 92 to move downward. Thus, the bar stock 10 can be pressed by the rotating column 92 to ensure the stability of the bar stock 10 during conveying. Moreover, when pressing the bar stock 10, the limiting sliding discs 94 are made to move closer to each other by the elastic force of the second spring 95. The mutually approaching surfaces of the limiting sliding discs 94 are arranged in a semi-circular arc shape. Thus, during the process of the support frame 91 driving the rotating column 92 to move downward, the bar stock 10 can be further clamped and limited by the two limiting sliding discs 94 to improve the stability of the bar stock 10 during conveying and cutting, and avoid the situation that the bar stock 10 is offset during conveying and cutting, which affects the cutting accuracy; When cutting the bar stock 10, the threaded rod 62 is driven to rotate, and the threaded rod 62 thread-drives the U-shaped sliding frame 63 to slide in the inner cavity of the groove 61. At the same time, the scale groove 8 is used to penetrate the position where the U-shaped sliding frame 63 moves. Then, the bar stock conveying assembly 3 is used to convey the bar stock 10 for feeding. Then, the bar stock 10 is abutted against the U-shaped sliding frame 63, and the length of the bolt blank is the distance from the cutting and grinding assembly 5 to the U-shaped sliding frame 63. Therefore, when cutting and processing bolts blanks in the same batch, there is no need to adjust the position of the U-shaped sliding frame 63. After the bar stock 10 is cut by the cutting and grinding assembly 5, the bar stock conveying assembly 3 automatically conveys the bar stock 10. After the bar stock 10 is abutted against the U-shaped sliding frame 63, the cutting and grinding assembly 5 is driven to cut the bar stock 10, thereby realizing the cyclic cutting and processing of bolt blanks and improving the production efficiency of bolts. After cutting the bolt blank from the bar stock 10, the weight of the bolt blank is used to drive the flip plate 73 to flip. At the same time, the flip plate 73 drives the rotating disk 74 to flip. Thus, the rotating disk 74 twists the torsion spring 75 and flips downward, so that the bolt blank slides out of the base 1 along the inclined flip plate 73 for collection. Then, the torsion spring 75 twists the rotating disk 74 to rotate, and the rotating disk 74 drives the flip plate 73 to rotate back to its original position, thereby waiting to receive the next bolt blank, and thus realizing the cyclic cutting and processing operation of bolt blanks.
