Description

Technical Field

[0001] This utility model relates to the field of medical tubing technology, and in particular to a cutting device. Background Technology

[0002] Stainless steel pipe is a hollow, long, round steel material. The main types of stainless steel pipe include austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, duplex stainless steel, and precipitation-hardening stainless steel. It is widely used in industrial pipelines for petroleum, chemical, medical, food, light industry, and machinery, as well as in mechanical structural components. Furthermore, while maintaining the same bending and torsional strength, it is lighter in weight, making it widely used in manufacturing mechanical parts and engineering structures, and also commonly used in furniture and kitchenware.

[0003] Currently, stainless steel pipe straightening and cutting devices rely on manual sampling using calipers. During normal operation, if the pipe diameter is defective, it's difficult to detect and take effective measures immediately, leading to product scrap. Furthermore, the low control precision and excessively long speed adjustment response time of these devices frequently result in pipe lengths exceeding process requirements, also causing product scrap.

[0004] It should be noted that the information disclosed in the background section of this invention is intended only to enhance the understanding of the general background of this utility model, and should not be regarded as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0021] like Figure 1 As shown, a cutting device 100 according to one embodiment includes a support assembly, a transmission assembly 120, a cutting assembly 130, a detection element 140, and a control device 150. This cutting device 100 is used to cut a target material. In this embodiment, the target material is a stainless steel tube, particularly a medical-grade stainless steel tube. It should be noted that stainless steel tubes are used as the target material in the following description. However, the target material can also be a polymer tube, etc.

[0022] Specifically, the support assembly includes a base plate 111 and a support frame 112 vertically mounted on the base plate 111. The base plate 111 and the support frame 112 can be fixedly connected by bolts or other means. A transmission assembly 120 is located on one side of the support frame 112, and a cutting assembly 130 is located on the other side of the support frame 112; that is, the transmission assembly 120 and the cutting assembly 130 are located on opposite sides of the support frame 112. The transmission assembly 120 includes rollers 121 and at least one set of servo motors. The servo motor set includes two first servo motors 122 spaced apart in a vertical direction, and the first servo motors 122 are equipped with rollers 121. Here, "vertical direction" refers to... Figure 1The Y-axis direction is shown. Two first servo motors 122 of the same servo motor group are coaxially arranged in the vertical direction. Rollers 121 correspond one-to-one with the first servo motors 122, and are connected to each other. The first servo motors 122 drive the rollers 121 to rotate. A stainless steel tube 200 is positioned between the two rollers 121 in the vertical direction, so that the first servo motors 122 drive the rollers 121 to rotate, thereby driving the stainless steel tube 200 forward, i.e., towards the direction of the cutting component. It should be noted that the minimum distance between the two rollers 121 in the same servo motor group is greater than or equal to the diameter of the stainless steel tube 200. Preferably, the minimum distance between the two rollers 121 in the same servo motor group is equal to the diameter of the stainless steel tube 200, thereby better driving the stainless steel tube 200 forward.

[0023] In one embodiment, the transmission assembly further includes a first rotating shaft 123, which corresponds one-to-one with a first servo motor 122. The first rotating shaft 123 connects the first servo motor 122 and the roller 121, that is, one end of the first rotating shaft 123 is connected to the first servo motor 122, and the other end is connected to the roller 121. Further, in one embodiment, the number of servo motor groups is three, and the three servo motor groups are spaced apart in the horizontal direction (i.e., the direction in which the stainless steel tube moves forward). Using multiple servo motor groups ensures that the stainless steel tube 200 maintains linear motion during transmission, thus achieving a straightening effect.

[0024] Additionally, a detection element 140 is mounted on the support frame 112. The detection element 140 has a through hole for a stainless steel tube 200 to pass through, specifically, the stainless steel tube 200 passes between the rollers 121 and through the through hole. The central axis of the through hole is collinear with the central axis of the stainless steel tube 200 after it passes through the rollers. The detection element 140 is used to detect the diameter of the stainless steel tube 200; that is, the diameter of the stainless steel tube 200 is detected when it passes through the through hole. The detection element 140 can be a laser detector.

[0025] The control device 150 is electrically connected to the transmission component, the cutting component, and the detection component 140. The control device 150 can be electrically connected to these components wirelessly or via a port. During operation, the control device 140 starts the first servo motor 122, which drives the roller 121 to rotate via the first rotating shaft 123, causing the stainless steel tube 200 to be transmitted forward. The stainless steel tube 200 passes through the through-hole on the detection component 140. At this time, the detection component 140 detects the diameter of the stainless steel tube 200 and sends this diameter to the control device 150. The control device 150 receives this diameter value and compares it with a preset value through a comparison circuit. If the diameter exceeds or falls below the preset value, the control device 150 sends an alarm message (such as an indicator light). After seeing the alarm message, the operator cuts off the portion of the stainless steel tube 200 that does not meet the requirements. If the diameter value received by the control device is the same as the preset value, the control device 150 activates the cutting component, which cuts the transmitted stainless steel tube 200. It should be noted that the cutting position of the cutting component is determined based on the length of the transmitted stainless steel tube 200. The control device 150 can be a PLC, etc. Through the setting of the detection component 140, the diameter of the stainless steel tube 200 is detected as it passes through its through-hole. If the diameter of the stainless steel tube 200 does not meet the requirements, the non-compliant portion can be cut off, thereby avoiding batch returns due to diameter defects and further reducing the scrap rate.

[0026] Furthermore, in one embodiment, the cutting assembly further includes a display device 160, which is connected to a control device 150. The control device 150 can be mounted on the detection element 140 via a support rod 151. The display device 160 can be a display screen, which can be used to display data such as the speed of the first servo motor.

[0027] The aforementioned cutting device includes a support assembly, a transmission assembly 120, a cutting assembly 130, a detection element 140, and a control device 150. The support assembly includes a base plate 111 and a support frame 112 vertically mounted on the base plate 111. The transmission assembly 120 and the cutting assembly 130 are located on opposite sides of the support frame 112. The transmission assembly includes rollers 121 and at least one set of servo motors. The servo motor set includes two first servo motors 122 spaced apart in a vertical direction. Rollers 121 are mounted on the first servo motors 122. The detection element 140 is mounted on the support frame 112 and has through holes. The detection element 140 is used to detect the diameter of the target cut-off part. The control device 150 is electrically connected to the transmission assembly 120, the cutting assembly 130, and the detection element 140. The target cut-off part is located between two rollers 121. When the target cut-off part needs to be cut, the control device 150 controls the first servo motor 122 to move, thereby driving the rollers 121 to rotate, so that the target cut-off part located between the rollers 121 is conveyed forward. The target cut-off part passes through the through hole on the detection element 140 and is conveyed to the cutting assembly. When the target cut-off part is conveyed to the preset position, the control device 150 controls the cutting assembly 130 to cut. By controlling the first servo motor 122 and the cutting assembly 130 through the control device 150, the target cut-off part is cut, improving cutting accuracy and reducing scrap rate. In addition, by setting the detection element 140, the diameter of the target cut-off part is detected when it passes through its through hole. If the diameter of the target cut-off part does not meet the requirements, the part that does not meet the requirements can be cut, thereby avoiding batch returns due to defective diameter and further reducing the scrap rate.

[0028] Please refer to Figure 2 In one embodiment, the cutting assembly 130 includes a second servo motor 131, a second rotating shaft 132, and a cutting blade 133. The second servo motor 131 is connected to the control device 150, the second rotating shaft 132 is connected to the second servo motor 131, and the cutting blade 133 is connected to the second rotating shaft 132. Therefore, when cutting is required, the control device 150 controls the second servo motor 131 to move, thereby driving the cutting blade 133 to rotate, thus achieving cutting.

[0029] Furthermore, the cutting assembly also includes a power component and a slider 134. The slider 134 is connected to the power component, and the second servo motor 131 is fixedly connected to the slider 134. The power component drives the slider 134 to move vertically, thereby driving the cutting blade 133 to move vertically. The slider 134 allows the cutting blade 133 to move; when not in use, the cutting blade can be moved upwards, thus improving safety. It should be noted that in one embodiment, a mounting bracket 1341 is fixedly installed on the slider 134. The second servo motor 131 is fixedly installed at one end of the mounting bracket 1341 and at its transmission end. A second rotating shaft 132 passes through the mounting bracket 1341, and the cutting blade 133 is fixedly installed on the second rotating shaft 132. The cutting assembly also includes a first movable ring 135, which is sleeved on the second rotating shaft 132 and fixedly installed inside the mounting bracket 1341. The first movable ring 135 provides a stabilizing effect.

[0030] Further, in one embodiment, the power assembly includes a third servo motor 136 and a lead screw 137. The third servo motor 136 is connected to the lead screw 137, and a slider 134 is movably mounted on the lead screw 137. When the third servo motor 136 drives the lead screw 137 to rotate, it in turn drives the slider 134 to move in the vertical direction. The lead screw 137 can be a threaded lead screw, which is fixedly mounted on the transmission end of the third servo motor. In one embodiment, the power assembly also includes a lifting box 138 and a second movable ring 139. The third servo motor 139 is located at the end of the lifting box 138, the lead screw 137 is located inside the lifting box 138, and the second movable ring 139 is also located inside the lifting box and is fixedly connected to the inner side of the other end of the lifting box 138. The second movable ring 139 is sleeved on the lead screw, providing a stabilizing effect. When the stainless steel pipe 200 needs to be cut, the third servo motor 136 drives the lead screw 137 to rotate, causing the slider 134 to move downwards. Then, the second servo motor 131 drives the second rotating shaft 132 and the cutting blade 133 to rotate, causing the cutting blade 133 to move downwards and cut the stainless steel pipe 200. By using the servo motor and control device, and taking advantage of the high precision, fast response speed, and good stability of the servo motor, the length of each cut can be precisely controlled, avoiding inconsistent product lengths.

[0031] Please refer to this again. Figure 1In one embodiment, the support assembly further includes a side plate 113, which is disposed on the base plate 111. A support frame 112 is perpendicularly connected to the side plate 113, meaning the side plate 113 is detachably connected to the side of the base plate 111, and the support frame 112 is disposed on the base plate 111. In this embodiment, a servo motor assembly is mounted on the side plate 113; that is, the first servo motor 122 is fixedly mounted on the side plate.

[0032] Furthermore, the support assembly also includes a horizontal plate 114, which is disposed on the side plate 113 and is vertically and fixedly connected to the side plate 113. The horizontal plate 114 is parallel to the bottom plate 111 and is located on the side of the support frame 112 away from the transmission assembly. The cutting assembly 130 is disposed on the side of the horizontal plate 114 near the support frame 112. As can be seen from the above, in this embodiment, the lifting box 138 is fixedly installed on the horizontal plate 114. In addition, the horizontal plate 114 is also used to receive the cut target part (stainless steel pipe), that is, when the stainless steel pipe 200 is cut by the cutting assembly installed on the horizontal plate 114, the cut part of the stainless steel pipe 200 is on the horizontal plate 114.

[0033] In one embodiment, the cutting device further includes a power component 170 and a receiving component (not shown in the figure). The power component 170 is mounted on the side plate 113 and is connected to the control device 150. The power component 170 is used to push the cut stainless steel tube. The receiving component is located between the horizontal plate 114 and the bottom plate 111. That is, when the stainless steel tube 200 is cut by the cutting assembly mounted on the horizontal plate 114, the cut portion of the stainless steel tube is on the horizontal plate 114. At this time, the control device 150 controls the power component 170 to start, so that the power component 170 pushes the cut portion of the stainless steel tube forward, thereby causing that portion of the stainless steel tube to fall off the horizontal plate 114 and into the receiving component, thus realizing the recycling of the product.

[0034] Furthermore, in one embodiment, the cutting device further includes support columns 180 and anti-slip components 190. The support columns 180 and anti-slip components 190 correspond one-to-one. The support columns 180 are mounted on the surface of the base plate 111 away from the support frame 112, and the anti-slip components 190 are disposed on the surface of the support columns 180 away from the base plate 111. The anti-slip components 190 improve the stability of the entire cutting device. The number of support columns 180 can be four, symmetrically arranged at the four corners of the base plate 111.
