Description

Technical Field

[0001] The present invention relates to the technical field of stainless steel bar drawing, and more particularly to an integrated machine for automatically drawing and cutting stainless steel bars. Background Art

[0002] Stainless steel bar drawing is a processing method in which, under normal temperature or heating conditions, an external force is applied to a stainless steel bar through a die, causing it to undergo plastic deformation to obtain a product with the required size and shape. This process mainly relies on the plasticity of the metal material. Through the stretching action, the stainless steel bar undergoes plastic flow under the constraint of the die, thereby changing its shape and size. Stainless steel bar drawing products are widely used in various fields such as construction, machinery manufacturing, automobile manufacturing, medical devices, etc.

[0003] During the stainless steel bar drawing process, as the number of drawing passes increases, the die will gradually wear, and the shape and size of the die hole will change. This may cause the stainless steel bar to be subjected to uneven tensile forces during drawing. Such uneven tensile forces can lead to defects such as cracks or pits on the surface of the stainless steel bar. Surface cracks and pits will weaken the tensile strength and ductility of the stainless steel bar, making it more prone to fracture or deformation when subjected to external forces, and will also affect the subsequent processing and surface treatment of the stainless steel bar, such as welding, electroplating, etc.; in addition, the prior art usually uses a hydraulic shear to cut the drawn stainless steel bar, but there is a lack of support for the steel bar during the cutting process, and the stainless steel bar is prone to shaking and displacement, which easily affects the cutting effect of the stainless steel bar.

[0004] How to invent an integrated machine for automatically drawing and cutting stainless steel bars to solve these problems has become an urgent problem for those skilled in the art. Summary of the Invention

The cooperation between the distance sensor and the control system can accurately identify and analyze the defects on the surface of the steel bar, improving the product quality and safety. At the same time, during the cutting operation, the gas is evenly transmitted to the installation cavity through the air guide branch and the connecting groove, pushing the sliding rod and the ball to tightly abut against the steel bar, forming a stable inelastic support structure, which helps to maintain the stability of the steel bar during the cutting process and prevent the cutting effect from being affected by vibration or shaking. The design of the inclined scraping part and the groove in the cleaning cylinder effectively scrapes the grease on the surface of the steel bar, preventing the accumulation or overflow of grease. The combined use of the collection tank, the discharge pipe and the collection box ensures the smooth discharge and centralized collection of grease, reducing environmental pollution and grease waste. The auxiliary discharge component can effectively dredge the possible blockage. At the same time, during the gas flow, a negative pressure area is formed inside the collection tank, which helps to adsorb impurities such as grease on the steel bar into the collection tank, further enhancing the cleaning effect.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0038] Example 1. Refer to Figures 1 - 9 , an automatic drawing and cutting integrated machine for stainless steel bars, including a base 1 and a steel bar 10. A box body 2, a front support 12, a mounting frame 11, and a rear support 13 are sequentially installed on the base 1 from left to right. The box body 2 is used to hold lubricating oil. A cleaning plug 21 is installed at the left end of the box body 2, and a coating sponge 22 is installed at the right end. The surface of the steel bar 10 can be cleaned through the cleaning plug 21 before lubrication, and the lubricating oil can be evenly coated on the steel bar 10 through the coating sponge 22. A drawing die 121 is installed on the front support 12 for drawing the steel bar 10 into the required specifications. A guide rail 111 is fixedly arranged on the mounting frame 11. A first motor 4 is installed on the right side of the rear support 13. The output end of the first motor 4 is fixedly connected to a first lead screw 41. The first lead screw 41 is rotatably connected to the front support 12 and the rear support 13. A mounting seat 42 is threadedly connected to the first lead screw 41. A slider 112 matching the guide rail 111 is fixedly installed on the lower side of the mounting seat 42. A clamping mechanism for clamping the steel bar 10 is fixedly arranged on the upper side of the mounting seat 42. When the first motor 4 is started, the first lead screw 41 starts to rotate. At this time, the mounting seat 42 will drive the slider 112 to slide along the guide rail 111 to cooperate with the clamping mechanism to perform the drawing operation. A hydraulic shear 3 for cutting the drawn steel bar 10 is fixedly connected to the rear support 13. It further includes:

[0039] Cleaning and temporary storage component: The cleaning and temporary storage component is arranged on the rear support 13 and is used for cleaning and collecting the grease on the steel bar 10.

[0040] Detection and support component: The detection and support component is arranged on the left side of the cleaning and temporary storage component. The detection and support component can detect the defects on the surface of the drawn steel bar 10 and can provide support for the steel bar 10 during the cutting operation.

[0041] Auxiliary discharging component: The auxiliary discharging component is arranged on the detection and support component. During the cutting operation, the auxiliary discharging component can assist the cleaning and temporary storage component in discharging materials.

[0042] Further, the clamping mechanism includes a clamping seat 5 fixedly connected to the upper side of the mounting seat 42. A clamping cavity 53 is provided inside the clamping seat 5. A second lead screw 511 and a guide rod 512 are rotatably connected to the clamping seat 5. A second motor 51 is fixedly installed on one side of the clamping seat 5. The output end of the second motor 51 is fixedly connected to the end of the second lead screw 511. Reverse threads are symmetrically arranged on the second lead screw 511 located inside the clamping cavity 53. A clamping block 52 is threadedly connected to each of the two threads of the second lead screw 511 in a symmetric manner. The lower ends of the two clamping blocks 52 are both slidably connected to the guide rod 512. An arc-shaped clamping groove is provided on the clamping block 52 facing the steel bar 10, and anti-slip patterns are provided on the arc-shaped clamping groove. By driving the second lead screw 511 to rotate through the second motor 51, the two clamping blocks 52 are made to move closer to or separate from each other under the guidance of the guide rod 512, thereby realizing the clamping or release of the steel bar 10. The arc-shaped clamping groove and anti-slip patterns on the clamping block 52 enhance the stability and safety of clamping.

[0043] The cleaning and temporary storage assembly includes a mounting cylinder 8 and a collection box 83. The mounting cylinder 8 is fixedly installed on the rear support 13. The collection box 83 is fixedly installed on the right side of the mounting cylinder 8 and is used to collect and store the grease discharged from the cleaning cylinder 9. A cleaning cylinder 9 is fixedly installed inside the mounting cylinder 8. A passage for the steel bar 10 to pass through is provided inside the cleaning cylinder 9. The design of this passage ensures that the steel bar 10 can be in close contact with the inner wall of the cleaning cylinder 9 when passing through, thereby effectively scraping off the grease on the surface. An inclined scraping portion 91 and a groove 92 are provided on the cleaning cylinder 9 corresponding to this passage. The groove 92 can provide additional grease collection space. A collection groove 911 is opened on the cleaning cylinder 9 at the front end of this passage for receiving the grease scraped off by the inclined scraping portion 91. The design of the collection groove 911 ensures that the grease can slide down smoothly and accumulate therein. A discharge pipe 93 is provided at the lower end of the collection groove 911. The end of the discharge pipe 93 penetrates through the side wall of the cleaning cylinder 9. The discharge pipe 93 is responsible for discharging the collected grease into the collection box 83. The design of the discharge pipe 93 ensures that the grease can flow out smoothly without clogging or accumulating inside the cleaning cylinder 9.

[0044] It should be noted that the discharge pipe 93 is located above the inner cavity bottom wall of the collection box 83, and the inclined scraping portion 91 is reduced in diameter to match the channel entrance. When the steel bar 10 passes through the channel, the inclined scraping portion 91 will scrape off the grease on the surface of the steel bar 10. Due to the design of the inclined scraping portion 91, the scraped-off grease can slide down smoothly instead of accumulating in the channel. The side wall of the steel bar 10 abuts against the inner wall of the channel in the cleaning cylinder 9. The cleaning cylinder 9 is made of fluororubber material, which has good wear resistance, corrosion resistance and elasticity, and can ensure a stable cleaning effect during long-term use. The grease scraped off by the inclined scraping portion 91 slides into the collection groove 911 and is then discharged into the collection box 83 through the discharge pipe 93 for collection.

[0045] In this embodiment, when the first motor 4 is started, the first lead screw 41 begins to rotate, and the mounting seat 42 moves along with the rotation of the lead screw. When the mounting seat 42 moves, the clamping mechanism also moves the steel bar 10 together. During this process, the steel bar 10 passes through the drawing die 121 on the front support 12 and is thus drawn into the required specification. After the steel bar 10 completes the drawing operation, it continues to move along the direction of the guide rail 111, passes through the channel of the cleaning cylinder 9, and reaches the position of the hydraulic shear 3. At this time, the hydraulic shear 3 is started, and the blade quickly cuts off the steel bar 10 under the push of the hydraulic cylinder. The cut steel bar 10 can be collected or further processed.

[0046] When the steel bar 10 is processed in the drawing and cutting integrated machine, it successively passes through the box body 2 (for lubrication treatment), the drawing die 121 (for drawing operation), and the cleaning cylinder 9 (for grease cleaning). When passing through the channel of the cleaning cylinder 9, the side wall of the steel bar 10 is in close contact with the inner wall of the cleaning cylinder 9, and the inclined scraping part 91 scrapes off the grease on the surface of the steel bar 10. The scraped grease then slides into the collection groove 911 and is discharged through the discharge pipe 93 into the collection box 83 for collection.

[0047] The groove 92 is located inside the cleaning cylinder 9 and together with the inclined scraping part 91 and the collection groove 911 constitutes a grease collection system. By opening the groove 92 on the wall of the cleaning cylinder 9, the storage space for grease can be increased, preventing the grease from accumulating or overflowing inside the cleaning cylinder 9. In addition, the presence of the groove 92 can also enhance the scraping effect of the cleaning cylinder 9 on the grease. When the steel bar 10 passes through the cleaning cylinder 9, its side wall contacts the edge of the groove 92, which helps to further scrape off the grease attached to the surface of the steel bar 10. In this way, the groove 92 and the inclined scraping part 91 work together to ensure that the grease on the surface of the steel bar 10 is completely removed.

[0048] Throughout the process, the cleaning and temporary storage assembly ensures the effective scraping and smooth discharge of the grease, which not only improves the surface cleanliness of the steel bar 10 but also prevents environmental pollution and waste of grease.

[0049] Embodiment 2, refer to Figures 3 - 12The detection support assembly includes a second pulley 6, a sliding rod 7, a first pulley 60 and an air intake pipe 81. The first pulley 60 is fixedly arranged on the first screw 41 and rotates with the first screw 41. A snap ring 61 is arranged at the right end of the second pulley 6, and a slot matching the snap ring 61 is arranged at the end of the mounting tube 8. The second pulley 6 is rotatably connected with the mounting tube 8 through the snap ring 61 and the slot. The air intake pipe 81 is located inside the mounting tube 8 and its end passes through the side wall of the mounting tube 8. An air supply pipe 82 is fixedly connected to the end of the air intake pipe 81 close to the hydraulic shear 3. An air guide groove 62 is arranged on one side of the second pulley 6 corresponding to the air intake pipe 81. The end of the air supply pipe 82 is connected with the output end of the external air supply pump to provide the system with the required gas (such as compressed air). The second pulley 6 is connected to the first pulley 60 through a belt 601. When the first pulley 60 rotates, the second pulley 6 will also rotate under the drive of the belt 601.

[0050] Furthermore, a plurality of mounting cavities 70, air guide branches 63, connecting grooves 64 and limiting cavities 75 are equidistantly arranged in a circular shape in the second pulley 6. One end of the mounting cavity 70 passes through the inner wall of the second pulley 6. The outer side of the slide bar 7 is fixedly connected to a limiting ring 72. The top of the limiting ring 72 is fixedly connected to a spring 74. The upper end of the spring 74 is fixedly connected to the top side wall of the limiting cavity 75. The mounting cavity 70 and the slide bar 7, the limiting ring 72 and the limiting cavity 75 are matched with each other. The up and down movement of the slide bar 7 will change the distance between the limiting ring 72 and the top of the limiting cavity 75, thereby changing the compression degree of the spring 74. This change can be monitored by the distance sensor 73. The end of the slide bar 7 located on the outer side of the second pulley 6 is rotatably clamped with a ball 71, and the end of the mounting cavity 70 away from the ball 71 is fixedly installed with a distance sensor 73. The distance sensor 73 can sense the position change of the slide bar 7 in real time, and feed this information back to the control system, so as to realize accurate detection of surface defects of the steel rod 10.

[0051] It should be noted that the end of the air guiding branch 63 penetrates through the side wall of the second pulley 6. The right end of the air guiding branch 63 corresponds to the air guiding groove 62. The limiting cavities 75 distributed along the axial direction of the second pulley 6 are communicated through the air guiding branch 63. The limiting cavities 75 distributed in a ring shape along the axis of the second pulley 6 are communicated through the connecting groove 64. Before the cutting operation is performed, at this time, the external air delivery pump ventilates the air delivery pipe 82, and the gas will enter the air guiding groove 62 through the air inlet pipeline 81, and be distributed into each installation cavity 70 through the air guiding branch 63 and the connecting groove 64. The pressure of the gas will push the limiting ring 72, so that the ball 71 can be tightly pressed against the surface of the steel rod 10, so as to realize the double-end limiting of the steel rod 10, avoid the situation that the steel rod 10 shakes during cutting, and improve the quality of the cut of the steel rod 10. The air guiding branch 63 is located above the limiting ring 72, and the side wall of the ball 71 abuts against the outer side wall of the steel rod 10. When there are defects on the surface of the steel rod 10, when the steel rod 10 moves, it will push the ball 71 and the sliding rod 7 to move up and down in the installation cavity 70.

[0052] In this embodiment, when the cutting operation of the steel rod 10 needs to be performed, the external air delivery pump starts to work, and conveys compressed air or other required gases through the air delivery pipe 82 into the air inlet pipeline 81. The gas entering the second pulley 6 is distributed into each installation cavity 70 through the air guiding branch 63 and the connecting groove 64. The designs of these air guiding branches 63 and connecting grooves 64 ensure that the gas can be evenly and effectively transmitted to each installation cavity 70. In each installation cavity 70, the sliding rod 7 is connected to the spring 74 through the limiting ring 72. When the gas enters the installation cavity 70, its pressure will push the limiting ring 72 (and the sliding rod 7) to move downward until the ball 71 abuts tightly against the outer side wall of the steel rod 10. When the ball 71 abuts tightly against the steel rod 10, a stable inelastic support structure will be formed, which helps to maintain the stability of the steel rod 10 during the cutting process and ensure the accuracy and safety of the cutting operation. After the cutting operation is completed, the spring 74 resets, and the gas will be discharged through the air guiding branch 63.

[0053] During the drawing process of the steel bar 10 (without ventilation), the first pulley 60 is fixedly arranged on the first lead screw 41 and rotates with the first lead screw 41. As the steel bar 10 continues to advance, when the first pulley 60 rotates, the second pulley 6 will also rotate driven by the belt 601, and the balls 71 thereon will keep in contact with the surface of the steel bar 10, so as to realize the omnidirectional detection of the steel bar 10. Under the action of the spring 74, the balls 71 will elastically contact the surface of the steel bar 10. The design of the balls 71 reduces the friction with the steel bar 10 and at the same time ensures good contact. When there are defects (such as cracks, depressions, etc.) on the surface of the steel bar 10, these defects will cause the contact force between the steel bar 10 and the balls 71 to change during the movement process, thereby causing the up and down movement of the slide bar 7 and the limit ring 72. This movement process is monitored in real time by the distance sensor 73. The distance sensor 73 can sense the position change of the slide bar 7 and feedback this information to the control system. The control system identifies and analyzes the defects on the surface of the steel bar 10 according to the information provided by the distance sensor 73. If an abnormal movement pattern (such as sudden up and down jumping or continuous offset) is detected, it may indicate that there are defects on the surface of the steel bar 10.

[0054] According to the severity and location of the defects, the control system can make different responses. For example, it can issue an alarm to prompt the operator to check the steel bar 10. At the same time, the control system can also adjust the cutting parameters or stop the cutting operation as needed to avoid damaging the equipment or producing unqualified products.

[0055] This detection and support component can monitor the position change of the slide bar 7 in real time during the drawing process to identify the defects on the surface of the steel bar 10, improving the product quality and safety. At the same time, it can effectively support the steel bar 10 during the cutting operation, helping to maintain the stability of the steel bar 10 during the cutting process and preventing it from affecting the cutting effect due to vibration or shaking. This component integrates functions such as gas transmission, steel bar 10 limiting, and surface detection, realizing the comprehensive monitoring and support of the steel bar 10 during the cutting and drawing processes.

[0056] Embodiment 3, referring to Figures 9 - 13 , the auxiliary discharging component includes a cleaning branch 65 arranged on the right side of the second pulley 6. The cross-section of the cleaning branch 65 is arranged in an inclined L shape, avoiding the reverse flow of grease into the cleaning branch 65. The lower end of the cleaning branch 65 is communicated with the air guide groove 62, and the upper end of the cleaning branch 65 penetrates through the side wall of the second pulley 6. A jet port is opened on the side wall of the cleaning cylinder 9 corresponding to the cleaning branch 65, and the end of the jet port penetrates through the side wall of the collection tank 911. During ventilation, a part of the gas will flow to the collection tank 911 through the cleaning branch 65 and the jet port.

[0057] It should be noted that the upper end of the cleaning branch 65 is located above the discharge pipe 93, which avoids grease from entering the cleaning branch 65. During the cutting operation, the upper end of the cleaning branch 65 is arranged towards the connection port of the collection tank 911 and the discharge pipe 93, ensuring that the blown gas can directly act on the connection port of the collection tank 911 and the discharge pipe 93, effectively dredging the possible blockage and ensuring that the grease can flow smoothly into the collection box 83. On the other hand, this design also cleverly utilizes the negative pressure effect. During the gas flow, it will form a certain negative pressure area inside the collection tank 911. This negative pressure area not only helps to adsorb impurities such as grease on the steel rod 10 into the collection tank 911, but also further enhances the cleaning effect.

[0058] In this embodiment, gas flow and blockage dredging: In the ventilation state, a part of the gas will enter the cleaning branch 65 through the air guide groove 62. Due to the cross-sectional design of the cleaning branch 65, the gas will maintain a certain speed and pressure during the flow. When the gas reaches the upper end of the cleaning branch 65, it will be sprayed into the collection tank 911 through the jet orifice.

[0059] Specifically, the upper end of the cleaning branch 65 is carefully arranged above the discharge pipe 93 and towards the connection port of the collection tank 911 and the discharge pipe 93. In this way, when the gas is blown out, it can directly act on this connection port, effectively dredging the possible blockage. This design ensures that impurities such as grease can smoothly flow through the discharge pipe 93 into the collection box 83, avoiding production interruption caused by blockage.

[0060] Negative pressure effect and impurity adsorption: At the same time, during the gas flow, it will form a negative pressure area inside the collection tank 911. This negative pressure area is formed when the gas is ejected from the jet orifice and the surrounding air is quickly sucked away. This negative pressure area not only helps to adsorb impurities such as grease on the steel rod 10 into the collection tank 911, but also further enhances the cleaning effect.

[0061] Specifically, when the gas is ejected from the jet orifice, it will form a high-speed air flow, which will drive the surrounding air to flow together, thus forming a low-pressure area inside the collection tank 911. Due to the existence of the pressure difference, impurities such as grease on the steel rod 10 will be adsorbed into the collection tank 911. At the same time, this negative pressure area will also accelerate the flow speed of impurities such as grease, making them flow into the collection box 83 faster.

[0062] Through the ingenious design of cleaning the branch passage 65 and the jet orifice, the auxiliary discharging assembly not only effectively dredges and cleans the connection port between the collecting tank 911 and the discharging pipe 93, but also enhances the cleaning effect by using the negative pressure effect. This design not only improves the collection efficiency of impurities such as grease, but also ensures the smooth progress of the cutting operation. At the same time, it also reduces the maintenance cost and downtime during the production process, and improves the overall production efficiency and product quality.
