Description

Technical Field

[0001] This utility model relates to the field of stainless steel cutting technology, and specifically to a stainless steel cutting device. Background Technology

[0002] Stainless steel is an alloy primarily composed of iron and chromium, and typically also contains other elements such as nickel, molybdenum, and manganese. It gets its name from its excellent corrosion resistance, maintaining good appearance and performance even under adverse climatic conditions. Therefore, stainless steel is commonly used to produce stainless steel pipes, stainless steel plates, etc. During the production of stainless steel products, dimensional deviations may occur, or customers may have specific requirements for the final dimensions. Cutting allows for precise adjustment of the product's length, width, or thickness to meet these needs, thus requiring cutting processing. For example, a stainless steel bar cutting device disclosed in application number CN202410718878.2 is used for cutting stainless steel products.

[0003] When cutting stainless steel pipes, existing cutting machines typically maintain a constant cutting pressure and a constant cutting blade rotation speed. However, since the hollow part of the stainless steel pipe is unsupported, when the cutting tool (circular cutting blade) enters, the cutting force must not only overcome the external material resistance but also consider the influence of the hollow part. Because the hollow part lacks material support, the resistance distribution during the actual cutting process becomes uneven. This leads to vibration and instability of the cutting tool, resulting in an uneven cut surface with wavy or irregular cutting edges. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a stainless steel cutting device that can effectively solve the problem that the existing technology cannot adjust the speed according to the actual cutting state of the stainless steel pipe.

[0017] 1. This utility model accurately measures a portion of the wall thickness and inner diameter of a stainless steel tube when it is vertically clamped. Then, it uses a second electric telescopic rod to move the top block. By changing the position of the resistance plate, the current in the first sliding rheostat changes.

The sprayed clean water can also leak back into the space below the filter plate 26 through the filter holes of the filter plate 26 for recycling.

[0035] The dimensions of stainless steel pipes are inspected using the following specific structural method, for reference. Figures 2 to 4The detection mechanism 3 includes a connecting plate 31 fixedly connected to the side wall of one of the extrusion plates 22 located above it. The top of the connecting plate 31 and the inner top wall of the cutting cover 1 are jointly provided with an infrared rangefinder 32. The cutting cover 1 is provided with a pipe inner diameter detection component, which includes a first sliding rheostat for detection.

[0036] The inner diameter detection component includes a first electric telescopic rod 33 fixedly connected to the inner wall of the cutting cover 1, an extension plate 34 fixedly connected to the telescopic end of the electric hydraulic rod, a second electric telescopic rod 35 fixedly connected to the top of the extension plate 34, a top block 36 fixedly connected to the telescopic end of the second electric telescopic rod 35, and a moving groove 37 opened at the top of the extension plate 34.

The first conductive sheet 38 and the first resistance plate 310 constitute the first sliding rheostat. The first conductive sheet 38 and the first resistance plate 310 are electrically connected to a PLC controller and form a first detection circuit. As the first resistance plate 310 slides upward on the surface of the first conductive sheet 38, the resistance of the first sliding rheostat in the first detection circuit gradually decreases.

[0038] The detection mechanism 3 also includes a third electric telescopic rod 311 fixedly connected to the top of the cutting cover 1. The telescopic end of the third electric telescopic rod 311 is fixedly connected to a cutting power box 312, and the cutting power box 312 contains a power shaft for transmitting power.

The PLC controller is electrically connected to the infrared temperature detector 314 and the water pump 214 to form a cooling circuit. Due to the extremely high hardness of diamond, the diamond cutting blade has extremely high wear resistance and can maintain a sharp cutting edge for a long time without being easily worn.

[0039] The inner wall of the cutting cover 1 is fixedly connected to a second resistance plate 315. The outer wall of the cutting power box 312 near the second resistance plate 315 is fixedly connected to a second conductive sheet 316, and the second conductive sheet 316 slides in contact with the second resistance plate 315. The second conductive sheet 316 and the second resistance plate 315 are electrically connected to a PLC controller to form a second detection circuit. The second conductive sheet 316 and the second resistance plate 315 constitute a second sliding rheostat. During the downward sliding process of the second conductive sheet 316 on the second resistance plate 315, the resistance of the second sliding rheostat in the second detection circuit gradually decreases. The PLC controller is electrically connected to the infrared rangefinder 32 to form a third detection circuit. The PLC controller is electrically connected to the third electric telescopic rod 311 and the cutting power box 312 to form a cutting circuit. The PLC controller has a built-in current detection module for detecting current and a calculation module for data calculation.

[0040] The working principle of this utility model is as follows:

[0041] First, the stainless steel pipe is placed horizontally between the clamping plate 21 and the extrusion plate 22. Then, the motor 28 is started, which drives the bidirectional lead screw 24 to rotate. Then, the transmission structure drives another bidirectional lead screw 24 to rotate. The clamping rod 29 moves on the bidirectional lead screw 24 toward the position of the stainless steel pipe through the limiting of the two bidirectional lead screws 24 and the sliding groove 27, so as to clamp the stainless steel pipe horizontally. At the same time, the two upper electric telescopic rods 212 and the two lower electric telescopic rods 211 are started, which in turn drives the extrusion plate 22 to clamp the stainless steel pipe vertically, so as to clamp the stainless steel pipe from all directions.

[0042] After the stainless steel tube is fixed by the upper extrusion plate 22, the distance that the extrusion plate 22 moves downward is measured by the infrared rangefinder 32.

[0043] Then, the first electric telescopic rod 33 is activated, which pushes the extension plate 34 forward, allowing the top block 36 to enter the stainless steel tube. The second electric telescopic rod 35 is then activated, causing the first resistance plate 310 to move synchronously, sliding on the first conductive sheet 38 and changing the current through the first sliding rheostat. The current detection module in the PLC controller then detects the current through the first sliding rheostat. When the current stops changing, it indicates that the top block 36 has completely reached the inner wall of the tube hole (the tube hole refers to the channel inside the stainless steel tube). The distance the top block 36 has moved is fed back from the change in current. The wall thickness of the stainless steel tube can be determined by the distance the top block 36 has moved and the distance measured by the infrared rangefinder 32. The specific calculation method is as follows:

[0044] Let the upper surface of the extension plate 34 be the horizontal plane x. In the initial state, the distance from the top block 36 to x is x1. The distance the top block 36 moves, as fed back by the current detection, is x2. In the initial state, the transmitter of the rangefinder on the upper surface of the connecting plate 31 is y. The distance y is from the position where the extrusion plate 22 contacts the stainless steel tube to y1. The distance after the extrusion plate 22 moves is y2. The distance from x to y is z. (y1+y2+x1+x2) is the wall thickness of the stainless steel tube. Based on the above data, the diameter of the stainless steel tube hole and the diameter of the stainless steel tube can also be obtained. By pre-measuring the distance from the horizontal centerline of the extension plate 34 to x as x3, the inner diameter of the tube hole is (x3+x1+x2)*2. The outer diameter of the stainless steel tube = the thickness of the stainless steel tube + the inner diameter of the stainless steel tube. The above calculations can be obtained in the calculation module of the PLC controller.

[0045] Based on the above calculations, the third electric telescopic rod 311 is started by controlling the PLC controller. The distance from the cutting blade 313 to the initial contact position between the extrusion plate 22 and the stainless steel pipe is measured beforehand. Assuming this distance is d, the extension length of the third electric telescopic rod 311 can be calculated using y²-d (the third electric telescopic rod 311 is a telescopic rod that can control the extension length and speed, and is existing technology). After the third electric telescopic rod 311 moves the cutting power box 312 downwards to the designated position, the power source in the cutting power box 312 is started by controlling the PLC controller, thereby driving the cutting blade 313... 13 rotates and slows down the descent speed of the third electric telescopic rod 311 to cut the stainless steel pipe. The cutting speed of the cutting blade 313 will be relatively slow (the initial cutting speed can be set at 10-20 mm / s) to ensure that the cutting blade 313 can stably cut into the stainless steel pipe wall. The lower speed helps the blade to make uniform contact with the material and avoids material deformation or burr formation caused by cutting too quickly. As the stainless steel pipe is continuously cut, the rotation speed of the cutting blade 313 will be gradually increased (the intermediate cutting speed can be increased to 30-50 mm / s). Appropriately increasing the cutting speed can reduce the cutting time and improve the cutting efficiency.

[0046] Then, based on the data calculated above, when the cutting blade 313 is about to cut into the pipe hole, the PLC controller controls the cutting blade 313 to slow down the cutting speed (the cutting speed at this time can be set to 10-20 mm / s). The slower speed helps to ensure the stability of the cutting equipment and the cutting quality, avoiding incomplete cutting or rough cutting edges. Then, the lower half of the stainless steel pipe is cut (repeating the cutting process of the upper plate). When the end of the pipe wall is cut, the cutting speed is reduced again (the final cutting speed can be reduced to 10-20 mm / s) to ensure the flatness and accuracy of the end cut.

[0047] At the start of cutting, a lower cutting pressure is typically used (provided via the third electric telescopic rod 311) (initial cutting pressure can be set at 50-100 psi) to avoid the blade cutting in too quickly, which could cause material deformation or uneven cut edges. Lower pressure helps ensure smooth contact between the blade and the material. During cutting, the cutting pressure is gradually increased (intermediate cutting pressure may increase to 150-200 psi) to improve cutting efficiency and depth. Appropriate pressure increases ensure that the cutting blade 313 can smoothly cut through the material, but the blade's durability must be ensured, especially when approaching the bore. When cutting near the tube hole, the cutting pressure needs to be reduced again (at this point, the cutting pressure can be set at 50-100 psi). This is because when cutting near the tube hole, the internal stress of the material will concentrate at the cutting edge and around the hole to be formed. Excessive cutting pressure may cause local stress concentration in the material, causing material deformation. Then continue cutting (repeating the cutting process of the first half). When cutting to the end of the tube wall, reduce the cutting pressure again (the final cutting pressure can be reduced to 50-100 psi) to ensure the flatness and accuracy of the end cut. Excessive pressure at the end of the cut can easily cause burrs or material deformation, so special attention is required.

[0048] As the cutting power box 312 moves downward, it drives the second conductive plate 316 to slide on the second resistance plate 315 to change the current through the second sliding rheostat. Then, the current detection module in the PLC controller detects the current change, and the calculation module in the PLC controller calculates the cutting depth based on the current change, thereby determining when to reduce or increase the pressure and speed.

[0049] Furthermore, high heat is generated during cutting. Therefore, at the beginning of cutting, the water pump 214 is started by controlling the PLC controller. The water pump 214 draws out the clean water in the space below the filter plate 26. Then, the clean water is divided into four water delivery chambers and two connecting chambers by the distributor 215. The water is discharged into the last two connecting chambers through the distributor pipe 219 and the drain pipe 220. Finally, the clean water is sprayed onto the grinding area by the booster nozzle 23.

[0050] When the infrared temperature detector 314 detects that the temperature of the cutting blade 313 is high, the PLC controller controls the water pump 214 to increase its power, so that more water is sprayed onto the cutting blade 313 and the cutting area to remove the heat generated during cutting more quickly.

[0051] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
