Description

Technical Field

[0001] This invention belongs to the field of stainless steel bar production, specifically stainless steel bar production and processing equipment. Background Technology

[0002] A key step in transforming stainless steel bars into precision parts is cutting them, which involves dividing long stainless steel bars into multiple bars of the required length. The general process is to first position the stainless steel bar to be cut in the required location, and then use the rotation of the cutting unit to bring the cutting structure into contact with the stainless steel bar to cut it.

[0003] A patent document with announcement number CN211614469U discloses a cutting device for producing stainless steel bars, including a housing, stainless steel bars, and support legs. By opening a feed hole on the left side of the housing, and cooperating with a feed guide on the inner wall of the left side of the housing, the feed guide, in conjunction with a guide block on the bottom wall of the housing, can prevent the stainless steel bars from not moving inside the housing.

[0004] In traditional technology, when stainless steel bars need to be cut to a fixed length, precise instruments are required to position and control the stainless steel bars to meet the requirements of fixed-length cutting. However, such instruments are relatively complex and have limited adaptability. They also rely heavily on transportation production lines for positioning, resulting in high production costs. Furthermore, it is difficult to support and limit the two ends of the stainless steel bar at the cutting position during cutting to ensure the flatness of the cut surface.

[0005] Therefore, the present invention provides stainless steel bar production and processing equipment to solve the problems mentioned in the background art. Summary of the Invention

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: the stainless steel bar production and processing equipment of the present invention includes a frame and a stainless steel bar placed on the frame. A cutting unit is also installed above the frame. A support unit is rotatably installed on the side of the frame. A drive unit is also installed on the side of the frame. The drive unit is used to drive the support unit to rotate. A linkage unit is installed inside the frame near the drive unit. A positioning slot is provided on the upper part of the frame. A push unit is slidably installed inside the positioning slot. The stainless steel rod is inserted into the positioning slot. The linkage unit is used to link the rotation of the support unit and the sliding operation of the push unit. The supporting unit includes a connecting shaft rotatably connected to the side of the drive unit and a connecting rod installed at one end of the connecting shaft. A supporting arc block is fixedly installed above one end of the connecting rod, and a limiting arc block is slidably installed above the supporting arc block. Both the limiting arc block and the supporting arc block have grooves inside that match the stainless steel rod body. A structural groove is also provided above the frame.

[0007] Preferably, the pushing unit includes a pushing circular block slidably mounted inside the positioning slot and two sliding blocks slidably mounted inside the upper part of the frame, the two sliding blocks being fixedly connected to the two sides of the pushing circular block.

[0008] Preferably, a guide column and a spiral column are rotatably mounted on the upper interior of the frame, one set of sliding blocks is sleeved on the outside of the guide column, and another set of sliding blocks is spirally sleeved on the outside of the spiral column, with the two sliding blocks on the same vertical plane.

[0009] Preferably, two sliding grooves are provided above the supporting arc block, and two connecting strips are fixedly installed below the limiting arc block. The two connecting strips are slidably installed inside the sliding grooves. A multi-stage telescopic rod is fixedly installed on the side of the connecting strip away from the drive unit. One end of the multi-stage telescopic rod is fixedly installed inside the sliding groove. The telescopic control limiting arc block of the two multi-stage telescopic rods slides above the supporting arc block.

[0010] Preferably, the drive unit includes a transmission box and a fixed motor fixedly mounted on the side of the frame, and one end of the connecting shaft is movably mounted inside the transmission box.

[0011] Preferably, the transmission box is equipped with a transmission structure inside, which drives the connecting shaft to rotate through the drive of the fixed motor and the cooperation of the transmission structure.

[0012] Preferably, a drive shaft and a spiral ring are rotatably mounted inside the transmission box, the drive shaft and the spiral ring are meshed together, and the spiral ring is fixedly sleeved on the outside of one end of the connecting shaft.

[0013] Preferably, the linkage unit includes an adjusting block slidably installed inside the structural groove and a rubber belt fixedly installed inside the structural groove, the rubber belt being fixedly connected to the outside of the adjusting block.

[0014] Preferably, a sliding column is slidably installed inside one end of the connecting shaft, and a connecting ring is rotatably installed on the outside of the sliding column. The connecting ring and the adjusting block are fixedly connected, and the sliding column slides axially inside the connecting shaft.

[0015] Preferably, a plurality of pins are fixedly installed on the outer side of the end of the sliding column facing the spiral column, and a groove is opened at one end of the spiral column facing the sliding column to match the sliding column and the plurality of pins. A fixing ring is also fixedly installed on one side of the spiral column facing the sliding column, and the diameter of the fixing ring is larger than the diameter of the groove at the end of the spiral column. The spiral column is rotatably installed inside the frame through the fixing ring.

[0016] The beneficial effects of this invention are as follows: 1. The stainless steel bar production and processing equipment of the present invention drives the support unit to rotate counterclockwise through the drive unit. During this process, the linkage unit cooperates to push the stainless steel bar towards the support unit. When the support unit completes the rotation, the end of the stainless steel bar will extend into the interior of the support arc block. The drive limiting arc block slides above the support arc block so that the two are no longer misaligned. That is, the end of the stainless steel bar will be supported and limited by the limiting arc block and the support arc block. At this time, the gap between the support unit and the frame is the cutting position, ensuring that the cutting of the stainless steel bar is a fixed-length cutting. Both ends of the part to be cut are supported and limited, which can ensure the flatness of the cut surface of the stainless steel bar.

[0017] 2. The stainless steel bar production and processing equipment of the present invention can link the spiral column and the support unit through the linkage unit. That is, when the drive unit drives, the spiral column and the support unit rotate simultaneously. When the spiral column rotates, the pushing block and the two sliding blocks will move inside the frame and the positioning slot. At this time, the guide column provides guidance for the movement of the pushing block and the two sliding blocks.

[0018] 3. The stainless steel bar production and processing equipment of the present invention uses a fixed motor to drive the drive shaft to rotate the spiral ring, which in turn drives the connecting shaft, connecting rod, supporting arc block and limiting arc block to rotate. At the same time, the connecting shaft is linked with the spiral column through the linkage unit. That is, when the connecting shaft rotates, the spiral column will rotate, which in turn drives the pushing unit to move the stainless steel bar, so as to complete the fixed length cutting work with a simple structure.

[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 1-5 As shown, the stainless steel bar production and processing equipment of this embodiment includes a frame 1 and a stainless steel bar 2 placed on the frame 1. A cutting unit 3 is also installed above the frame 1. A support unit 4 is rotatably installed on the side of the frame 1. A drive unit 5 is also installed on the side of the frame 1. The drive unit 5 is used to drive the support unit 4 to rotate. A linkage unit 6 is installed inside the frame 1 near the drive unit 5. A positioning slot 11 is provided on the upper part of the frame 1. A push unit 12 is slidably installed inside the positioning slot 11. A stainless steel rod 2 is inserted into the positioning slot 11. The linkage unit 6 is used to link the rotation of the support unit 4 and the sliding operation of the push unit 12. The supporting unit 4 includes a connecting shaft 44 rotatably connected to the side of the drive unit 5 and a connecting rod 43 installed at one end of the connecting shaft 44. A supporting arc block 42 is fixedly installed above one end of the connecting rod 43. A limiting arc block 41 is slidably installed above the supporting arc block 42. Both the limiting arc block 41 and the supporting arc block 42 have grooves inside that match the stainless steel rod body 2. A structural groove 13 is also provided above the frame 1.

[0024] Specifically, in this device, the initial position of the pushing unit 12 is at the extreme position inside the positioning slot 11, away from the supporting unit 4. At this time, the supporting unit 4 is in a vertical state below one side of the frame 1 (i.e., Figure 1(As shown in the diagram), at this point, the supporting unit 4 does not obstruct the stainless steel rod 2 from being inserted into the positioning slot 11. After the stainless steel rod 2 is inserted into the positioning slot 11, one end of it contacts the side of the pushing unit 12. Driven by the driving unit 5, the connecting shaft 44 drives the connecting rod 43, the supporting arc block 42, and the limiting arc block 41 to rotate on the side of the frame 1, so that the supporting unit 4 is in a lateral state. At this time, the center of the limiting arc block 41 and the supporting arc block 42 is on the same axis as the center of the stainless steel rod 2. While the supporting unit 4 is rotating, the pushing unit 12 moves towards the supporting unit 4 inside the positioning slot 11 through the linkage unit 6, thereby driving the stainless steel rod 2 to move until the end of the stainless steel rod 2 is flush with the side of the frame 1 facing the supporting unit 4 (i.e., Figure 2 In the initial stage (medium state), the cutting preparation is completed. Driven by the drive unit 5, the support unit 4 rotates 360 degrees counterclockwise. During the rotation, the limiting arc block 41 slides above the support arc block 42, causing them to be misaligned. During this process, the linkage unit 6 cooperates to push the push unit 12 to move the stainless steel rod 2 towards the support unit 4. After the support unit 4 completes the rotation, the end of the stainless steel rod 2 will extend into the interior of the support arc block 42. Drive the limiting arc block 41 to slide above the support arc block 42 so that they are no longer misaligned. That is, the end of the stainless steel rod 2 will be supported and limited by the limiting arc block 41 and the support arc block 42. At this time, the gap between the support unit 4 and the frame 1 is the position to be cut. The cutting unit 3 rotates to cut the stainless steel rod 2. A portion of the stainless steel rod 2 that is cut off is inside the support unit 4, while the stainless steel rod that is cut off is inside the positioning slot 11. One end of the rod 2 remains flush with the side of the frame 1 near the support unit 4, ready for the next cut. This ensures that the cutting of the stainless steel rod 2 is a fixed-length cut. Driven by the drive unit 5, the support unit 4 rotates 360 degrees counterclockwise again, pushing the stainless steel rod 2 to cut again, completing the automated fixed-length cutting. At this time, the support unit 4 contains the cut stainless steel rod 2 inside. Through the staggered state of the limiting arc block 41 and the supporting arc block 42, this part of the stainless steel rod 2 is unloaded. In this device, a fixed-length cut of the stainless steel rod 2 is achieved through a simple structure. When cutting the stainless steel rod 2, both ends of the part to be cut are supported and limited, which can ensure the flatness of the cut surface of the stainless steel rod 2. When it is necessary to push the unit 12 to return to the initial position, the linkage structure of the linkage unit 6 can be disconnected, and the pushing unit 12 can be moved to the initial position, ready for the next cut.

[0025] like Figures 3-4As shown, the pushing unit 12 includes a pushing circular block 121 that is slidably installed inside the positioning slot 11 and two sliding blocks 122 that are slidably installed inside the frame 1 above it. The two sliding blocks 122 are fixedly connected to the two sides of the pushing circular block 121.

[0026] A guide post 14 and a spiral post 15 are rotatably mounted inside the upper part of the frame 1. A set of sliding blocks 122 are sleeved on the outside of the guide post 14, and another set of sliding blocks 122 are spirally sleeved on the outside of the spiral post 15. The two sliding blocks 122 are on the same vertical plane.

[0027] Specifically, the linkage unit 6 can link the spiral column 15 with the support unit 4. That is, when the drive unit 5 drives, the spiral column 15 and the support unit 4 rotate simultaneously. When the spiral column 15 rotates, the push block 121 and the two sliding blocks 122 will move inside the frame 1 and the positioning slot 11. At this time, the guide column 14 provides guidance for the movement of the push block 121 and the two sliding blocks 122.

[0028] like Figure 5 As shown, two sliding grooves 421 are provided above the supporting arc block 42, and two connecting bars 412 are fixedly installed below the limiting arc block 41. The two connecting bars 412 are slidably installed inside the sliding grooves 421. A multi-stage telescopic rod 411 is fixedly installed on the side of the connecting bar 412 away from the drive unit 5. One end of the multi-stage telescopic rod 411 is fixedly installed inside the sliding groove 421. The extension and retraction control of the two multi-stage telescopic rods 411 causes the limiting arc block 41 to slide above the supporting arc block 42.

[0029] Specifically, the retraction of the multi-stage telescopic rod 411 can drive the connecting strip 412 to move inside the sliding groove 421, so that the limiting arc block 41 and the supporting arc block 42 are in a staggered state. At this time, when the supporting unit 4 rotates counterclockwise until it is in a horizontal state, the supporting arc block 42 will support the lower side of the end of the stainless steel rod 2. The extension of the multi-stage telescopic rod 411 causes the connecting strip 412 to move inside the sliding groove 421 until the limiting arc block 41 and the supporting arc block 42 overlap, that is, the limiting arc block 41 covers the upper side of the end of the stainless steel rod 2, that is, it supports and limits the end of the stainless steel rod 2, which is beneficial for the subsequent cutting and processing of the stainless steel rod 2.

[0030] like Figures 5-6 As shown, the drive unit 5 includes a transmission box 51 fixedly installed on the side of the frame 1 and a fixed motor 52, with one end of the connecting shaft 44 movably installed inside the transmission box 51.

[0031] The transmission box 51 has a transmission structure inside, which drives the connecting shaft 44 to rotate through the drive of the fixed motor 52 and the cooperation of the transmission structure.

[0032] Inside the transmission box 51, a drive shaft 53 and a spiral ring 54 are rotatably mounted. The drive shaft 53 and the spiral ring 54 are meshed together, and the spiral ring 54 is fixedly sleeved on the outside of one end of the connecting shaft 44.

[0033] Specifically, the drive shaft 53 is driven by the fixed motor 52 to rotate the spiral ring 54, which in turn drives the connecting shaft 44, connecting rod 43, supporting arc block 42 and limiting arc block 41 to rotate. At the same time, the connecting shaft 44 is linked with the spiral column 15 through the linkage unit 6. That is, when the connecting shaft 44 rotates, the spiral column 15 will rotate, which in turn drives the pushing unit 12 to push the stainless steel rod 2 to move, so as to complete the fixed length cutting work with the simple structure.

[0034] Example 2: Figure 7 As shown in the first embodiment, another embodiment of the present invention is as follows: the linkage unit 6 includes an adjustment block 61 that is slidably installed inside the structural groove 13 and a rubber belt 62 that is fixedly installed inside the structural groove 13. The rubber belt 62 is fixedly connected to the outside of the adjustment block 61.

[0035] A sliding column 64 is slidably installed inside one end of the connecting shaft 44, and a connecting ring 63 is rotatably installed on the outside of the sliding column 64. The connecting ring 63 and the adjusting block 61 are fixedly connected, and the sliding column 64 slides axially inside the connecting shaft 44.

[0036] Multiple pins 65 are fixedly installed on the outer side of the end of the sliding column 64 facing the spiral column 15. A groove matching the sliding column 64 and the multiple pins 65 is opened on one end of the spiral column 15 facing the sliding column 64. A fixing ring 151 is also fixedly installed on the side of the spiral column 15 facing the sliding column 64. The diameter of the fixing ring 151 is larger than the diameter of the groove at the end of the spiral column 15. The spiral column 15 is rotatably installed inside the frame 1 through the fixing ring 151.

[0037] Specifically, when the connecting shaft 44 and the spiral post 15 rotate simultaneously, the pin 65 and the end of the sliding post 64 will insert into the end of the spiral post 15. The rotation of the connecting shaft 44 will drive the sliding post 64 and the spiral post 15 to rotate, thus achieving concentric rotation of the spiral post 15 and the connecting shaft 44. That is, the supporting unit 4 rotates counterclockwise one revolution, and the pushing unit 12 pushes the stainless steel rod 2 to move a certain distance. After the stainless steel rod 2 is cut, the supporting unit 4 needs to rotate back to its initial position (i.e.,...). Figure 1(State), but the pushing unit 12 has not returned to its initial position. By pushing the adjusting block 61 to move inside the structural groove 13, the adjusting block 61 and the connecting ring 63 cause the sliding column 64 and the pins 65 to no longer be inserted into the spiral column 15. That is, the spiral column 15 no longer rotates concentrically with the connecting shaft 44. At this time, when the pushing unit 12 is pushed to move inside the positioning slot 11, the spiral column 15 is driven to rotate until the pushing unit 12 returns to its initial position. Since the spiral column 15 is connected by a spiral, the groove opened in the end of the spiral column 15 still matches the sliding column 64 and the multiple pins 65. Pushing the sliding column 64 and the connecting ring 63 again causes the multiple pins 65 of the sliding column 64 to be inserted into the spiral column 15, so that the spiral column 15 and the connecting shaft 44 can rotate concentrically, ready for the next cutting use.

[0038] Working principle: In this device, the initial position of the pushing unit 12 is at the extreme position inside the positioning slot 11, away from the supporting unit 4. At this time, the supporting unit 4 is in a vertical state below one side of the frame 1 (i.e., Figure 1 (As shown in the diagram), at this point, the supporting unit 4 does not obstruct the stainless steel rod 2 from being inserted into the positioning slot 11. After the stainless steel rod 2 is inserted into the positioning slot 11, one end of it contacts the side of the pushing unit 12. Driven by the driving unit 5, the connecting shaft 44 drives the connecting rod 43, the supporting arc block 42, and the limiting arc block 41 to rotate on the side of the frame 1, so that the supporting unit 4 is in a lateral state. At this time, the center of the limiting arc block 41 and the supporting arc block 42 is on the same axis as the center of the stainless steel rod 2. While the supporting unit 4 is rotating, the pushing unit 12 moves towards the supporting unit 4 inside the positioning slot 11 through the linkage unit 6, thereby driving the stainless steel rod 2 to move until the end of the stainless steel rod 2 is flush with the side of the frame 1 facing the supporting unit 4 (i.e., Figure 2In the intermediate state, the initial preparation for cutting and processing is completed. Driven by the drive unit 5, the support unit 4 rotates 360 degrees counterclockwise. During this rotation, the limiting arc block 41 slides above the support arc block 42, causing them to misalign. Simultaneously, with the cooperation of the linkage unit 6, the pushing unit 12 pushes the stainless steel rod 2 towards the support unit 4. Once the support unit 4 has completed its rotation, the end of the stainless steel rod 2 extends into the interior of the support arc block 42. The driving limiting arc block 41 slides above the support arc block 42, preventing them from misaligning. Thus, the stainless steel rod... The end of body 2 is supported and limited by the limiting arc block 41 and the supporting arc block 42. At this time, the gap between the supporting unit 4 and the frame 1 is the position to be cut. The stainless steel rod 2 is cut by the rotation of the cutting unit 3. A part of the stainless steel rod 2 that is cut off is inside the supporting unit 4. After cutting, one end of the stainless steel rod 2 inside the positioning slot 11 is still flush with the side of the frame 1 near the supporting unit 4, ready for the next cut. It is ensured that the cutting of the stainless steel rod 2 is a fixed length cut. The supporting unit 4 is driven by the driving unit 5 to perform a 360-degree reverse rotation. As the clock hand rotates, it pushes the stainless steel rod 2 to cut again, completing the automated fixed-length cutting process. At this time, the supporting unit 4 rotates, containing the cut stainless steel rod 2. Through the staggered state of the limiting arc block 41 and the supporting arc block 42, this portion of the stainless steel rod 2 is unloaded. This device achieves fixed-length cutting of the stainless steel rod 2 through a simple structure. Furthermore, during cutting, both ends of the part to be cut are supported and limited, ensuring the flatness of the cut surface of the stainless steel rod 2. When it is necessary to push the unit 12 back to its initial position... The linkage structure of linkage unit 6 can be disconnected, and the pushing unit 12 can be moved to the initial position in preparation for the next cut. When the connecting shaft 44 and the spiral column 15 rotate simultaneously, the pin 65 and the end of the sliding column 64 will be inserted into the end of the spiral column 15. When the connecting shaft 44 rotates, it will drive the sliding column 64 and the spiral column 15 to rotate, thereby realizing that the spiral column 15 and the connecting shaft 44 rotate concentrically. That is, the supporting unit 4 rotates counterclockwise one revolution, and the pushing unit 12 pushes the stainless steel rod 2 to move a certain distance. After the stainless steel rod 2 is cut, the supporting unit 4 needs to rotate back to the initial position (i.e., Figure 1(State), but the pushing unit 12 has not returned to its initial position. By pushing the adjusting block 61 to move inside the structural groove 13, the adjusting block 61 and the connecting ring 63 cause the sliding column 64 and the pins 65 to no longer be inserted into the spiral column 15. That is, the spiral column 15 no longer rotates concentrically with the connecting shaft 44. At this time, when the pushing unit 12 is pushed to move inside the positioning slot 11, the spiral column 15 is driven to rotate until the pushing unit 12 returns to its initial position. Since the spiral column 15 is connected by a spiral, the groove opened in the end of the spiral column 15 still matches the sliding column 64 and the multiple pins 65. Pushing the sliding column 64 and the connecting ring 63 again causes the multiple pins 65 of the sliding column 64 to be inserted into the spiral column 15, so that the spiral column 15 and the connecting shaft 44 can rotate concentrically, ready for the next cutting use.
