Description

Technical Field

[0001] The invention relates to the technical field of stainless steel bar drawing, in particular to an automatic stainless steel bar drawing and cutting integrated machine. Background Art

[0002] Stainless steel bar drawing is a processing method that applies external force to stainless steel bars through a die at room temperature or under heating conditions to cause plastic deformation, thereby obtaining products of the desired size and shape. This process mainly relies on the plasticity of metal materials. Through the stretching effect, the stainless steel bars undergo plastic flow under the constraints of the die, thereby changing their shape and size. Stainless steel bar drawing products are widely used in various fields, such as construction, machinery manufacturing, automobile manufacturing, medical equipment, etc.

[0003] During the drawing process of stainless steel bars, as the number of drawing times increases, the die will gradually wear, and the shape and size of the die channels will change, which may cause the stainless steel bars to be subjected to uneven tensile force during the drawing process. This uneven tensile force will cause defects such as cracks or pits to form on the surface of the stainless steel bars. The surface cracks and pits will weaken the tensile strength and ductility of the stainless steel bars, making them more likely to break or deform when subjected to external forces, and will also affect the subsequent processing and surface treatment of the stainless steel bars, such as welding and electroplating. In addition, the prior art usually uses hydraulic shears to cut the drawn stainless steel bars, but lacks support for the steel bars during the cutting process, and the stainless steel bars are prone to shaking and displacement, which can easily affect the cutting effect of the stainless steel bars.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1, refer to Figure 1-Figure 9 A stainless steel rod automatic drawing and cutting integrated machine comprises a base 1 and a steel rod 10. A box 2, a front support 12, a mounting frame 11 and a rear support 13 are installed on the base 1 from left to right. The box 2 is used to hold lubricating oil. A cleaning plug 21 is installed at the left end of the box 2 and a smearing sponge 22 is installed at the right end. The cleaning plug 21 can be used to clean the surface of the steel rod 10 before lubrication. The smearing sponge 22 can be used to evenly apply the lubricating oil to the steel rod 10. A drawing die 121 is installed on the front support 12 for drawing the steel rod 10 into the required specifications. A guide rail 111 is fixedly provided on the mounting frame 11. A first electric The first motor 4 has a first lead screw 41 fixedly connected to the output end thereof, and 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, and 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 drives 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 steel bar 10 after drawing is fixedly connected to the rear support 13, and further includes:

[0039] Cleaning and temporary storage component: The cleaning and temporary storage component is arranged on the rear support 13, and the cleaning and temporary storage component is used to clean and collect grease on the steel rod 10;

[0040] Detection support assembly: The detection support assembly is arranged on the left side of the cleaning temporary storage assembly. The detection support assembly can detect defects on the surface of the steel rod 10 after drawing, and can provide support for the steel rod 10 during the cutting operation;

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

[0042] Furthermore, the clamping mechanism includes a clamping seat 5 fixedly connected to the upper side of the mounting seat 42, a clamping cavity 53 is arranged 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, an output end of the second motor 51 is fixedly connected to the end of the second lead screw 511, and the second lead screw 511 located in the clamping cavity 53 is symmetrically provided with reverse threads, and the two sections of the threads of the second lead screw 511 are symmetrically arranged with each thread. The steel bar 10 is connected to a clamping block 52 with a groove, and the lower ends of the two clamping blocks 52 are slidably connected to the guide rod 512. An arc-shaped clamping groove is arranged on the clamping block 52 facing the steel bar 10, and an anti-slip groove is arranged on the arc-shaped clamping groove. The second lead screw 511 is driven to rotate by the second motor 51, so that the two clamping blocks 52 are guided by the guide rod 512 to move toward or separate from the middle, thereby clamping or releasing the steel bar 10. The arc-shaped clamping groove and the anti-slip groove on the clamping block 52 enhance the stability and safety of clamping.

[0043] The cleaning temporary storage assembly includes a mounting cylinder 8 and a collecting box 83. The mounting cylinder 8 is fixedly mounted on the rear support 13. The collecting box 83 is fixedly mounted on the right side of the mounting cylinder 8 and is used to collect and store grease discharged from the cleaning cylinder 9. The cleaning cylinder 9 is fixedly mounted inside the mounting cylinder 8. The cleaning cylinder 9 is provided with a channel for the steel rod 10 to pass through. The design of the channel ensures that the steel rod 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. The cleaning cylinder 9 corresponding to the channel is provided with an oblique scraping portion 91 and a groove 92 The groove 92 can provide additional grease collection space. A collection groove 911 is provided on the cleaning cylinder 9 at the front end of the channel for receiving the grease scraped off by the oblique scraping portion 91. The design of the collection groove 911 ensures that the grease can smoothly slide down 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 passes 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 being blocked or accumulated in the cleaning cylinder 9.

[0044] It should be noted that the discharge pipe 93 is located above the bottom wall of the inner cavity of the collecting box 83, and the oblique scraping part 91 is reduced in diameter to match the entrance of the channel. When the steel rod 10 passes through the channel, the oblique scraping part 91 will scrape off the grease on the surface of the steel rod 10. Due to the design of the oblique scraping part 91, the scraped grease can slide down smoothly instead of accumulating in the channel. The side wall of the steel rod 10 is against the inner wall of the channel in the cleaning tube 9. The cleaning tube 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 oblique scraping part 91 slides into the collecting groove 911 and is discharged into the collecting 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 starts to rotate, and the mounting seat 42 moves with the rotation of the lead screw. When the mounting seat 42 moves, the clamping mechanism also moves with the steel rod 10. During this process, the steel rod 10 passes through the drawing die 121 on the front support 12, thereby being drawn into the required specifications. When the steel rod 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, until it reaches the position of the hydraulic shear 3. At this time, the hydraulic shear 3 is started, and the blade is pushed by the hydraulic cylinder to quickly cut off the steel rod 10. The cut steel rod 10 can be collected or further processed.

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

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

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

[0049] Example 2, refer to Figure 3-Figure 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 guide branch 63 passes through the side wall of the second pulley 6, the right end of the air guide branch 63 corresponds to the air guide groove 62, the limiting cavities 75 distributed along the axial direction of the second pulley 6 are connected through the air guide branch 63, and the limiting cavities 75 distributed in an annular manner along the axis of the second pulley 6 are connected through the connecting groove 64. Before the cutting operation is performed, the external air pump ventilates the air delivery pipe 82, and the gas enters the air guide groove 62 through the air intake pipe 81, and is distributed to the air guide groove 62 through the air guide branch 63 and the connecting groove 64. Inside each installation cavity 70, the pressure of the gas will push the limit ring 72, so that the ball 71 can be tightly against the surface of the steel rod 10, so as to achieve double-end limitation of the steel rod 10, avoid the shaking of the steel rod 10 when cutting, and improve the quality of the incision of the steel rod 10. The air guide branch 63 is on the upper side of the limit ring 72, and the side wall of the ball 71 is against the outer wall of the steel rod 10. When a defect appears on the surface of the steel rod 10, when the steel rod 10 moves, it will push the ball 71 and the slide rod 7 to move up and down in the installation cavity 70.

[0052] In this embodiment, when it is necessary to perform the cutting operation of the steel rod 10, the external air pump starts working and delivers compressed air or other required gas to the air intake pipe 81 through the air pipe 82. The gas entering the second pulley 6 is distributed to the inside of each installation cavity 70 through the air guide branch 63 and the connecting groove 64. The design of these air guide branches 63 and the connecting groove 64 ensures that the gas can be evenly and effectively delivered to each installation cavity 70. In each installation cavity 70, the slide bar 7 is connected to the spring 74 through the limit ring 72. When the gas enters the installation cavity 70, its pressure will push the limit ring 72 (and the slide bar 7) to move downward until the ball 71 is tightly against the outer wall of the steel rod 10. When the ball 71 is tightly against the steel rod 10, a stable non-elastic support structure will be formed, which will help 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 is reset and the gas will be discharged through the air guide branch 63.

[0053] During the pulling process of the steel rod 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 rod 10 continues to move forward, when the first pulley 60 rotates, driven by the belt 601, the second pulley 6 will also rotate, and the ball 71 thereon will keep in contact with the surface of the steel rod 10, thereby realizing all-round detection of the steel rod 10; under the action of the spring 74, the ball 71 will elastically contact with the surface of the steel rod 10. The design of the ball 71 reduces the friction between the steel rod 10 and ensures good contact. When there is a friction between the steel rod 10 and the surface of the steel rod 10, the second pulley 6 will also rotate. When there are defects (such as cracks, dents, etc.), these defects will cause the contact force between the steel rod 10 and the ball 71 to change during movement, thereby causing the slide bar 7 and the limit ring 72 to move up and down. 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 feed this information back to the control system. The control system identifies and analyzes the defects on the surface of the steel rod 10 based on the information provided by the distance sensor 73. If an abnormal movement pattern is detected (such as sudden up and down jumps or continuous offsets), it may indicate that there are defects on the surface of the steel rod 10.

[0054] Depending on the severity and location of the defect, the control system can respond differently. For example, it can sound 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] The detection support component can monitor the position change of the slide bar 7 in real time during the drawing process to identify defects on the surface of the steel bar 10, thereby improving product quality and safety. At the same time, it can effectively support the steel bar 10 during the cutting operation, which helps to maintain the stability of the steel bar 10 during the cutting process and prevent it from affecting the cutting effect due to vibration or shaking. The component integrates functions such as gas transmission, steel bar 10 limiting and surface detection, thereby realizing comprehensive monitoring and support of the steel bar 10 during the cutting and drawing process.

[0056] Example 3, refer to Figure 9-13 The auxiliary discharge assembly 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 to prevent grease from flowing back into the cleaning branch 65. The lower end of the cleaning branch 65 is connected to the air guide groove 62, and the upper end of the cleaning branch 65 passes through the side wall of the second pulley 6. A jet port is provided on the side wall of the cleaning cylinder 9 corresponding to the cleaning branch 65, and the end of the jet port passes through the side wall of the collecting groove 911. During ventilation, part of the gas will flow to the collecting groove 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 prevents grease from entering the cleaning branch 65. During the cutting operation, the upper end of the cleaning branch 65 is arranged toward the connection port between the collecting tank 911 and the discharge pipe 93, ensuring that the blown gas can directly act on the connection port between the collecting tank 911 and the discharge pipe 93, effectively clearing possible blockages 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 flow of gas, 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 flows and clears blockages: in the ventilation state, a portion of the gas will enter the cleaning branch 65 through the gas 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 process. When the gas reaches the upper end of the cleaning branch 65, it will be sprayed into the collection tank 911 through the jet port.

[0059] In particular, the upper end of the cleaning branch 65 is carefully arranged above the discharge pipe 93 and faces the connection between 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 to effectively clear the possible blockage. This design ensures that impurities such as grease can flow smoothly through the discharge pipe 93 to the collection box 83, avoiding production interruption caused by blockage.

[0060] Negative pressure effect and impurity adsorption: At the same time, during the flow of gas, it will form a negative pressure area inside the collection tank 911. This negative pressure area is formed when the surrounding air is quickly drawn away when the gas is ejected from the jet nozzle. 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 port, it forms a high-speed airflow, which will drive the surrounding air to flow together, thereby forming a low-pressure area inside the collection tank 911. Due to 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, allowing them to flow into the collection box 83 faster.

[0062] Through the ingenious design of the cleaning branch 65 and the air jet, the auxiliary discharge component not only realizes the effective dredging and cleaning of the connection between the collection tank 911 and the discharge 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 cutting operation. At the same time, it also reduces the maintenance cost and downtime in the production process, and improves the overall production efficiency and product quality.
