Description

Technical Field

[0001] This invention belongs to the field of stainless steel bolt processing and cutting technology, specifically a cutting device for processing stainless steel bolts. Background Technology

[0002] In the production and processing of stainless steel bolts, the first step is to cut long stainless steel bars into sections of blanks. This blanking process, though seemingly simple, directly determines the quality of subsequent cold heading. Cutting is typically done using a circular cold saw for single-bar cutting and a metal band saw for multi-bar cutting. The cut blanks then undergo visual inspection and necessary deburring, and are sorted and stacked according to specifications. This provides qualified blanks for subsequent cold heading, thread rolling, heat treatment, and surface treatment processes, ensuring the precision and strength of the finished bolts.

[0003] Existing metal band saw cutting devices include a saw band mechanism, a fixing mechanism, a feeding mechanism, a feeding rack, and a feeding and stacking mechanism. In use, bundles of bar stock are placed on the feeding and stacking mechanism, which sorts and stacks the bundles of bar stock into "square stacks" placed on the feeding rack. Then, the feeding mechanism clamps the "square stacks" and pulls them toward the fixing mechanism. Next, the fixing mechanism clamps the "square stacks" and the saw band mechanism cuts the "square stacks," thus achieving the cutting of multiple bar stock at once.

[0004] In the above scheme, after the bundled bars are placed on the feeding and stacking mechanism, the feeding and stacking mechanism breaks down the bundled bars one by one, and then stacks the bars one by one onto the feeding rack. This results in a very complex structure and a large footprint for the feeding and stacking mechanism, which not only leads to high equipment investment costs, but also troublesome maintenance in the later stage. Therefore, the present invention provides a cutting device for processing stainless steel bolts. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a cutting device for processing stainless steel bolts, including a saw blade mechanism, a fixing mechanism is provided inside the saw blade mechanism, a feeding mechanism is provided behind the fixing mechanism, and a feeding mechanism is provided behind the feeding mechanism. The feeding mechanism includes a main frame body, the main frame body is directly opposite the feeding mechanism, several pairs of support rollers are equidistantly installed on the main frame body, the support rollers are rotatably installed on the support rollers, several sets of correction plates are rotatably installed at equal distances on both sides of the main frame body, two guide columns are symmetrically rotatably installed on the correction plates, the output end of the hydraulic cylinder is hinged to the lower end of the correction plate, and the tail end of the hydraulic cylinder is hinged to the main frame body. Each pair of support rollers consists of two support rollers, and a synchronous gear is provided at one end of the support rollers. The synchronous gear meshes with a synchronous toothed belt. By setting the feeding mechanism, the material bars can be stacked in a square pile on the main frame after the steel strip is removed, without the need to disassemble and sort the material bars, making the device structure simpler, reducing the equipment investment cost and facilitating later maintenance.

[0007] Preferably, the correction plate is also provided with a shearing mechanism, which includes two sets of cutters, the cutters are slidably mounted on the correction plate, the connecting rods at the tail of the cutters are hinged, the two ends of the rotating rod are hinged to two sets of connecting rods, the pin is fixedly mounted on the rotating rod, the output end of the first cylinder is hinged to the pin, the shearing mechanism also includes a fixed frame, the fixed frame is fixedly mounted on the correction plate, the middle of the rotating rod is rotatably connected to the fixed frame, the tail of the first cylinder is hinged to the fixed frame, the correction plate is provided with a rectangular groove, and slide rails are provided on both sides of the upper part of the rectangular groove. The two sets of slide rails slidably connect the two sets of cutters, and drive the two sets of cutters to move towards each other along the slide rails so that the two sets of cutters cut the steel strips tied on the material bar; The first cylinder pushes the pin shaft to drive the rotating rod to rotate. The rotating rod drives two sets of cutters to move towards each other along the corresponding slide rails through two sets of connecting rods. At the same time, the ends of the two sets of cutters cut the steel strip, so that the steel strip tied to the bar is cut at the same time. This not only improves the automation rate of the device, but also improves the overall efficiency of the bar cutting process.

[0008] Preferably, the feeding mechanism further includes several sets of unloading mechanisms. The unloading mechanism includes a dropping box, which is fixedly installed in the main frame body. A second cylinder is fixedly installed on one end of the dropping box. A push plate is fixedly installed on the output end of the second cylinder. Several sets of scrap boxes for placing the steel strip that slides out of the dropping box are arranged at equal intervals on one side of the main frame body. A set of dropping boxes is distributed between every two sets of correction plates. A clearance groove is opened on the correction plate. The end of the dropping box is located in the clearance groove. The shearing mechanism further includes a pre-positioning mechanism. The pre-positioning mechanism includes two sets of fixing blocks, which are installed on two sets of cutting tools. A guide post is movably inserted into the fixing block. A spring is sleeved on the guide post. A pressure plate is fixedly connected to the ends of the two sets of guide posts. Under the influence of gravity, the lower half of the steel bar will automatically fall into the material box. Then, the push plate driven by the second cylinder will push the lower half of the steel bar to move along the inner cavity of the material box, so that the lower half of the steel bar is pushed out of the material box and falls into the waste box, realizing the rapid collection of the steel bar and further improving the overall efficiency of the bar cutting process.

[0009] The beneficial effects of this invention are as follows: 1. By setting the feeding mechanism, the material bars can be stacked in a square pile on the main frame after the steel strip is removed, without the need to disassemble and sort the material bars, making the device structure simpler, reducing the equipment investment cost, and facilitating later maintenance.

[0010] 2. During the process of driving the two sets of cutters to cut the steel bar, the lifting device remains hooked to the lifting ring on the steel strip. The moving cutters drive the fixing block, guide post, and pressure plate to move together. Before the cutters contact the steel bar, the pressure plate will contact the steel bar in advance. As the cutters continue to move, the steel bar will be clamped between the two sets of pressure plates. At the same time, the fixing block slides along the guide post and compresses the spring until the cutters cut the steel bar. At this time, due to the clamping force of the two sets of pressure plates, the lower half of the steel bar will not bounce off due to its own tension, causing the steel bar to... If the lower half of the strip cannot fall precisely into the lower feeding box, the upper half of the steel strip is lifted away by the lifting device. At the same time, the two sets of cutters are driven to separate, releasing the clamps of the two sets of pressure plates on the lower half of the steel strip. Under the action of gravity, the lower half of the steel strip will automatically fall into the feeding box. Then, the second cylinder drives the push plate to push the lower half of the steel strip along the inner cavity of the feeding box, so that the lower half of the steel strip is pushed out of the feeding box and falls into the waste box, realizing the rapid collection of the steel strip and further improving the overall efficiency of the bar cutting process.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] Example 1: As Figures 1 to 4 As shown in the embodiment of the present invention, a cutting device for processing stainless steel bolts includes a saw blade mechanism 1, a fixing mechanism 2 is provided inside the saw blade mechanism 1, a feeding mechanism 3 is provided behind the fixing mechanism 2, and a feeding mechanism 4 is provided behind the feeding mechanism 3. The feeding mechanism 4 includes a main frame 401, which faces the feeding mechanism 3. Several pairs of support rollers 402 are equidistantly installed on the main frame 401. The support rollers 402 are rotatably mounted on the main frame 401. Several sets of correction plates 403 are rotatably mounted at equal distances on both sides of the main frame 401. Two guide columns 404 are symmetrically rotatably mounted on the correction plates 403. The output end of a hydraulic cylinder 405 is connected to the lower end of the correction plate 403, and the tail of the hydraulic cylinder 405 is hinged to the main frame 401. Each pair of support rollers 402 consists of two support rollers 402. A synchronous gear 406 is provided at one end of the support roller 402, and the synchronous gear 406 meshes with a synchronous toothed belt 407.

[0024] Specifically, in the initial state, the clamps on the feeding mechanism 3 are in the closed state, and the material bar 5 is bundled into a square stack by steel straps. Lifting rings are installed on the steel straps. When cutting is required, the material bar 5 is lifted onto the main frame 401 using lifting equipment, and several pairs of support rollers 402 lift the material bar 5. Then, a motor drives one of the support rollers 402 in each pair to rotate. This support roller 402, through the transmission of synchronous gears 406 and synchronous toothed belts 407, causes the other support roller 402 to rotate. The rotating support roller 402 moves the material bar 5 towards the feeding mechanism 3 until the end of the material bar 5 touches the clamps on the feeding mechanism 3. At this point, the motor driving the support roller 402 is de-energized, and several sets of hydraulic cylinders 405 are simultaneously activated. The hydraulic cylinders 405 push the correction plate 403 to rotate until the guide post 40 on the correction plate 403... 4. The material bar 5 is squeezed to the side, so that the square stack of material bar 5 is clamped between several sets of correction plates 403 to correct the position of material bar 5. The square stack of material bar 5 is located between several sets of correction plates 403. Then, the steel strip on the material bar 5 is cut off and removed. The end of the material bar 5 is clamped by the feeding mechanism 3 and continuously fed to the fixing mechanism 2 until the end of the material bar 5 enters the fixing mechanism 2. The fixing mechanism 2 fixes the end of the material bar 5. Then, the sawing mechanism 1 cuts the material bar 5. The above operation is repeated so that the material bar 5 is cut into multiple short material bars. Compared with the prior art, by setting the material feeding mechanism 4, the material bar 5 can be stacked in a square stack on the main frame 401 after the steel strip is removed. There is no need to split and sort the material bar 5, which makes the device structure simpler, reduces the equipment investment cost of the device, and facilitates later maintenance.

[0025] Example 2: Figure 5 and Figure 6 As shown in Example 1, another embodiment of the present invention is as follows: The correction plate 403 is also equipped with a shearing mechanism 408, which includes two sets of cutters 4081. The cutters 4081 are slidably mounted on the correction plate 403. A connecting rod 4082 is hinged to the tail of the cutter 4081. Two sets of connecting rods 4082 are hinged to both ends of the rotating rod 4083. A pin 4084 is fixedly mounted on the rotating rod 4083. The output end of the first cylinder 4085 is hinged to the pin 4084. The shearing mechanism 408 also includes a fixing frame 4086. 6 is fixedly installed on the correction plate 403. The middle part of the rotating rod 4083 is rotatably connected to the fixing frame 4086. The tail of the first cylinder 4085 is hinged to the fixing frame 4086. A rectangular groove 4031 is opened on the correction plate 403. Slide rails 4032 are provided on both sides of the upper part of the rectangular groove 4031. The two sets of slide rails 4032 are slidably connected to the two sets of cutters 4081. The two sets of cutters 4081 are driven to move towards each other along the slide rails 4032, so that the two sets of cutters 4081 cut the steel strip tied on the material bar 5.

[0026] Specifically, when cutting the steel strips on the bar 5, since there are many steel strips tied on the bar 5, cutting them one by one would take a lot of time and reduce the overall efficiency of the cutting process of the bar 5. Therefore, when the square stack of bar 5 is clamped between several sets of correction plates 403, the steel strip on the bar 5 is exactly positioned between the two sets of cutters 4081 on each set of shearing mechanism 408. Then, the first cylinder 4085 is activated, and the first cylinder 4085 pushes the pin 4084 to drive the rotating rod 4083 to rotate. The rotating rod 4083 drives the two sets of cutters 4081 to move towards each other along the corresponding slide rail 4032 through two sets of connecting rods 4082. At the same time, the ends of the two sets of cutters 4081 cut the steel strip, so that the steel strip bound on the bar 5 is cut at the same time. This not only improves the automation rate of the device, but also improves the overall efficiency of the bar 5 cutting process.

[0027] like Figure 7 and Figure 9 As shown, the feeding mechanism 4 also includes several sets of unloading mechanisms 409. Each unloading mechanism 409 includes a dropping box 4091, which is fixedly installed inside the main frame 401. A second cylinder 4092 is fixedly installed on one end of the dropping box 4091, and a push plate 4093 is fixedly installed on the output end of the second cylinder 4092. Several sets of scrap boxes 410 for placing the steel strip sliding out of the dropping box 4091 are equidistantly arranged on one side of the main frame 401. Between every two sets of correction plates 403... The shearing mechanism 408 includes a set of feed boxes 4091, a correction plate 403 with a relief groove 4033, and the end of the feed box 4091 located in the relief groove 4033. The shearing mechanism 408 also includes a pre-positioning mechanism 4087, which includes two sets of fixing blocks 871, which are mounted on two sets of cutters 4081, a guide post 872 movably inserted into the fixing block 871, a spring 873 sleeved on the guide post 872, and a pressure plate 874 fixedly connected to the ends of the two sets of guide posts 872.

[0028] Specifically, after the steel strips are cut, the large number of steel strips, and the fact that the steel strips are cut into two ends, results in an increased number of steel strips, making collection troublesome and time-consuming. During the process of cutting the steel bar using the two sets of cutting tools 4081, the lifting device remains hooked to the lifting ring on the steel strip. The moving cutting tool 4081 drives the fixing block 871, guide post 872, and pressure plate 874 to move together. Before the cutting tool 4081 contacts the steel bar, the pressure plate 874 will contact the steel bar in advance. As the cutting tool 4081 continues to move, the steel bar will be clamped between the two sets of pressure plates 874. At the same time, the fixing block 871 slides along the guide post 872 and compresses the spring 873 until the cutting tool 4081 cuts the steel bar. At this time, due to the clamping force of the two sets of pressure plates 874, the lower half of the steel bar will not bounce off due to its own tension. This phenomenon causes the lower half of the steel strip to not fall accurately into the lower material box 4091. At this time, the upper half of the steel strip is lifted away by the lifting device, and at the same time, the two sets of cutters 4081 are driven to separate, releasing the clamping of the lower half of the steel strip by the two sets of pressure plates 874. Under the action of gravity, the lower half of the steel strip will automatically fall into the material box 4091. Then, the second cylinder 4092 drives the push plate 4093 to push the lower half of the steel strip along the inner cavity of the material box 4091, so that the lower half of the steel strip is pushed out of the material box 4091 and falls into the waste box 410, realizing the rapid collection of the steel strip and further improving the overall efficiency of the cutting process of the material bar 5.

[0029] Working principle: The material bar 5 is lifted onto the main frame 401 by a hoisting device, and several pairs of support rollers 402 support the material bar 5. Then, a motor drives one of the support rollers 402 in each pair to rotate. This support roller 402 drives the other support roller 402 to rotate through the transmission of synchronous gear 406 and synchronous toothed belt 407. The rotating support roller 402 drives the material bar 5 to move towards the feeding mechanism 3 until the end of the material bar 5 touches the clamp on the feeding mechanism 3. At this time, the motor driving the support roller 402 is de-energized. Then, several sets of hydraulic cylinders 405 are activated simultaneously. The hydraulic cylinders 405 push the correction plate 403. Rotate until the guide post 404 on the correction plate 403 presses against the side of the bar 5, so that the bar 5 in a square stack is clamped between several sets of correction plates 403, thereby correcting the position of the bar 5. The bar 5 is then in a square stack between several sets of correction plates 403. Then the steel strip on the bar 5 is cut off and removed. The end of the bar 5 is clamped by the feeding mechanism 3 and continuously fed into the fixing mechanism 2 until the end of the bar 5 enters the fixing mechanism 2. The end of the bar 5 is fixed by the fixing mechanism 2. Then the bar 5 is cut by the sawing mechanism 1. Repeat the above operation to cut the bar 5 into multiple short bars. When the square stack of bar 5 is clamped between several sets of correction plates 403, the steel strip on the bar 5 is exactly positioned between the two sets of cutters 4081 on each set of shearing mechanism 408. Then, the first cylinder 4085 is activated. The first cylinder 4085 pushes the pin 4084 to drive the rotating rod 4083 to rotate. The rotating rod 4083 drives the two sets of cutters 4081 to move towards each other along the corresponding slide rail 4032 through two sets of connecting rods 4082. At the same time, the ends of the two sets of cutters 4081 cut the steel strip, so that the steel strip tied on the bar 5 is cut at the same time. During the process of driving the two sets of cutters 4081 to cut the steel bar, the lifting device remains hooked to the lifting ring on the steel strip. The moving cutter 4081 drives the fixing block 871, guide post 872, and pressure plate 874 to move together. Before the cutter 4081 contacts the steel bar, the pressure plate 874 will contact the steel bar in advance. As the cutter 4081 continues to move, the steel bar will be clamped between the two sets of pressure plates 874. At the same time, the fixing block 871 slides along the guide post 872 and compresses the spring 873 until the cutter 4081 cuts the steel bar. At this time, due to the clamping force of the two sets of pressure plates 874, the steel bar... The lower half of the steel strip will not bounce due to its own tension, preventing it from falling accurately into the lower material box 4091. At this time, the upper half of the steel strip is lifted away by the lifting device, and the two sets of cutters 4081 are driven to separate, releasing the clamping of the lower half of the steel strip by the two sets of pressure plates 874. Under the action of gravity, the lower half of the steel strip will automatically fall into the material box 4091. Then, the second cylinder 4092 drives the push plate 4093 to push the lower half of the steel strip along the inner cavity of the material box 4091, so that the lower half of the steel strip is pushed out of the material box 4091 and falls into the waste box 410.
