Description

Technical Field

[0001] The invention relates to the technical field of stainless steel composite plate milling devices, in particular to a milling device for carbon steel and stainless steel composite plates. Background Art

[0002] A milling device is a mechanical device used to perform milling processes, which can cut workpieces through a rotating milling cutter. Milling is one of the most common cutting methods used to remove excess parts of metal or other materials to obtain the desired shape, size and surface quality. A milling device usually includes a series of mechanical systems, tools and accessories to ensure accurate and efficient processing.

[0003] The milling of carbon steel and stainless steel composite plates is a process involving two different metal materials. Carbon steel and stainless steel each have different physical and chemical properties, so their differences need to be considered during the milling process to ensure processing quality and tool life. Carbon steel has better processing performance and lower hardness, and is usually easier to cut. It tends to generate more heat during processing, so it requires reasonable cooling and lubrication. Stainless steel is usually harder, wear-resistant, and easy to generate cutting heat. It has higher strength, so stainless steel has more stringent requirements on tools during processing.

[0004] The existing milling devices used for processing carbon steel and stainless steel composite plates have the following technical problems: 1. Tool vibration problem: During the milling process, especially during high-speed cutting or long-term deep cutting, the machine tool may be affected by vibration and resonance, causing the processing tool to vibrate, thereby affecting the processing accuracy and workpiece quality, and may also cause tool damage or surface quality problems. 2. Tool cooling problem: The function of the coolant is to reduce the tool temperature, reduce the fluctuation of the cutting force, and prevent the workpiece from overheating. However, uneven coolant supply, unstable flow, and poor cooling effect will lead to thermal stress, premature tool wear and other problems during the processing process.

[0005] Traditional coolants are mostly oil-based coolants or water-based coolants, the latter of which may cause environmental pollution. In particular, as the problem of wastewater treatment becomes increasingly serious, industries with high environmental protection requirements are facing greater pressure. Summary of the invention

The present invention provides a milling device for a carbon steel and stainless steel composite plate, wherein a distribution box is arranged on the base of the milling device, a moving component is arranged in the middle of the base, a first support column and a second support column are respectively arranged on both sides of the inside of the base, an X-axis moving component, a Y-axis moving component and a Z-axis moving component are respectively arranged on the first support column and the second support column, an anti-vibration component is arranged on the Z-axis moving component, and a cooling component is arranged on the X-axis moving component; the moving component of the milling device comprises a support plate located in the base, a first motor located at one end of the base is arranged on the support plate, the first motor is connected to a first lead screw, first slide rails located on both sides of the support plate are arranged on both sides of the first lead screw, a workbench is arranged on the first lead screw and the first slide rail, a workbench is arranged on the workbench, and a workpiece is arranged on the workbench. The milling device for the carbon steel and stainless steel composite plate has a simple overall structure, is easy to install and operate, and is convenient for staff to perform milling and maintenance.

[0018] 2. The present invention provides a milling device for a carbon steel and stainless steel composite plate. The X-axis moving component, Y-axis moving component and Z-axis moving component designed in the milling device perform fine machining to achieve the required size and surface quality after completing rough machining. The cylinder drives the piston rod to move, pushing the support frame to move on the Y-axis. In addition, the second lead screw rotates under the drive of the second motor, driving the slider on the second lead screw to move. Since the transmission shaft is installed on the slider, the movement of the slider drives the transmission shaft above the milling tool to move horizontally in the X-axis direction, and cooperates with the movement of the Z-axis moving component in the vertical direction. According to the size requirements of the composite plate workpiece, the movement of the milling tool on the X-axis, Y-axis and Z-axis is realized, thereby obtaining a workpiece that better meets the size requirements, improving the machining accuracy of the milling tool, and improving the machining efficiency of the workpiece.

[0019] 3. The present invention provides a milling device for carbon steel and stainless steel composite plates. The milling device is designed with a shockproof component, which includes a first connecting member connected to a transmission shaft, telescopic rods are arranged on both sides of the first connecting member, a buffer spring is arranged on the telescopic rod, and a second connecting member is arranged below the buffer spring. Since the milling device will generate vibration during the milling process, especially during long-term milling processing, the shockproof component will compress the telescopic rod with the external force generated by the vibration, and the axial expansion and contraction of the telescopic rod compresses the buffer spring therein, and the buffer spring is deformed and absorbs vibration, thereby reducing the influence of vibration on the milling tool, allowing the milling tool to process the workpiece more smoothly, thereby obtaining a higher quality processed workpiece.

[0020] 4. The present invention provides a milling device for a carbon steel and stainless steel composite plate, wherein a cooling component of the milling device includes a magnetic base located on a support frame, a compressor is arranged on the magnetic base, a switch valve is connected to one side of the compressor, an air cavity is arranged on the compressor, one end of the air cavity is connected to a universal guide tube, one end of the universal guide tube is arranged with a nozzle, and an injection hole is arranged on the nozzle. During the milling process, with the long-term use of the milling tool, the cutting temperature gradually increases. Excessive temperature will cause the surface of the workpiece to harden, increase tool wear, and may affect the processing accuracy. At this time, the switch valve of the cooling component is opened, and air is introduced inwardly. The compressor compresses the air to expand. When the gas expands, it absorbs heat from the surrounding environment. The expanded gas enters the air cavity, flows into the universal guide tube connected to the air cavity, and is ejected through the injection hole on the nozzle at one end of the universal guide tube. Since the temperature of the ejected gas can be reduced to a very low level, the milling tool and the workpiece are cooled, the surface hardening of the workpiece caused by high temperature is prevented, tool wear is reduced, and the processing accuracy of the workpiece is improved.

[0035] See also Figures 1 to 11 The magnetic base 1201 of the cooling component 12 is coaxially arranged with the compressor 1202, the axis of the compressor 1202 is perpendicular to the axis of the air cavity 1204, the universal guide tube 1205 is located between the air cavity 1204 and the nozzle 1206, and a plurality of jet holes 1207 are arranged on the nozzle 1206.

[0036] The working principle and specific working process of a milling device for carbon steel and stainless steel composite plates are as follows: According to the processing requirements of the workpiece 6 of the carbon steel stainless steel composite plate, before starting milling, check the material, thickness, surface condition, etc. of the stainless steel composite plate to ensure that the material meets the processing requirements; determine the processing path and process parameters, and formulate reasonable processing paths, feed speeds, cutting depths and other process parameters according to the size, shape and required processing accuracy of the stainless steel composite plate.

[0037] According to the plate thickness, material and processing method of the workpiece 6 to be processed, select a suitable milling tool 903, install the milling tool 903 on the transmission shaft 902, ensure that the milling tool 903 is firmly installed, and correctly set the working coordinates of the milling tool 903; set various parameters of the milling device according to the processing requirements: cutting depth, feed speed, spindle speed and other parameters to ensure reasonable coordination between the milling tool 903 and the workpiece 6 on the workbench 504.

[0038] The second motor 701, the cylinder 803 and the third motor 901 of the X-axis moving component 7, the Y-axis moving component 8 and the Z-axis moving component 9 of the milling device are started respectively to move the milling tool 903 to a suitable position. The third motor 901 drives the transmission shaft 902 to operate. The rotation of the transmission shaft 902 drives the milling tool 903 to move up and down in the Z-axis direction. First, rough machining is performed to remove most of the excess material. A larger cutting depth and a higher feed speed can be selected during rough machining, but attention should be paid to the material differences of the stainless steel composite plate. Different metals have different cutting properties, especially the outer layer of the composite plate The stainless steel is usually harder, which can easily cause tool wear.

[0039] After completing the rough machining, fine machining is performed to achieve the required size and surface quality. The cylinder 803 drives the piston rod 804 to move, pushing the support frame 703 to move on the Y axis. At the same time, the second lead screw 702 rotates under the drive of the second motor 701, driving the slider 704 on the second lead screw 702 to move. Since the transmission shaft 902 is installed on the slider 704, the movement of the slider 704 drives the transmission shaft 902 above the milling tool 903 to move horizontally in the X-axis direction, and cooperates with the movement of the Z-axis moving component 9 in the vertical direction. According to the size requirements of the composite plate workpiece 6, the movement of the milling tool 903 on the X-axis, Y-axis, and Z-axis is realized, and the workpiece 6 is finely machined. During fine machining, the tool cutting depth is small and the feed speed is low to ensure surface finish and reduce the generation of internal stress.

[0040] Since the milling device will vibrate during the milling process, especially during long-term milling, the base 1 of the milling device may be affected by vibration and resonance, causing the machining tool to vibrate, thereby affecting the machining accuracy and the quality of the workpiece 6, and may also cause damage to the tool or surface quality problems. The external force generated by the vibration compresses the telescopic rod 1103, and the axial expansion and contraction of the telescopic rod 1103 compresses the buffer spring 1104 inside it. The buffer spring 1104 deforms and absorbs the vibration, thereby reducing the impact of the vibration on the milling tool 903, allowing the milling tool 903 to process the workpiece 6 more smoothly, thereby avoiding affecting the machining quality of the workpiece 6. During the milling process, as the milling tool 903 is used for a long time, the cutting temperature gradually increases. Excessive temperature will cause the surface of the workpiece 6 to harden, increase tool wear, and may affect the processing accuracy. At this time, the switch valve 1203 of the cooling component 12 is opened, and air is introduced inward. The compressor 1202 compresses the air to expand. When the gas expands, it absorbs heat from the surrounding environment. The expanded gas enters the air cavity 1204 and flows into the universal duct 1205 connected to the air cavity 1204, and is ejected through the jet hole 1207 on the nozzle 1206 at one end of the universal duct 1205. At this time, the temperature of the ejected gas can be reduced to a very low level, thereby cooling the milling tool 903 and the workpiece 6.

[0041] After milling, the workpiece 6 is deburred and sharpened to avoid affecting subsequent use. After processing, the final size and surface quality inspection is performed to ensure that it meets the design requirements.

[0042] The same and similar parts between the various embodiments in this specification can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0043] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
