Description

Technical Field

[0001] The present invention relates to roll milling, and in particular to a gantry milling machine for manufacturing high-nickel-chromium-molybdenum centrifugally composite rolls. Background Art

[0002] The high-nickel-chromium-molybdenum centrifugally composite roll is a high-performance roll. The working layer of the roll body contains relatively high alloy elements such as nickel, chromium, and molybdenum, and its core usually uses high-strength ductile iron. The high content of alloy elements endows the roll with good wear resistance and thermal crack resistance.

[0003] Due to the high mechanical properties of the high-nickel-chromium-molybdenum centrifugally composite roll, namely high hardness, high wear resistance, and high thermal crack resistance, and its generally large volume, the machining performance of the high-nickel-chromium-molybdenum centrifugally composite roll is relatively low.

[0004] Currently, when machining a high-nickel-chromium-molybdenum centrifugally composite roll, especially during surface milling, due to the high surface hardness of the high-nickel-chromium-molybdenum centrifugally composite roll, the tool wears significantly during milling, and the milling cutter needs to be frequently replaced. At present, when milling such high-nickel-chromium-molybdenum centrifugally composite rolls, a milling machine is mostly used, and manual operation is required for tool changing. After machining, the tool has a large amount of heat energy, and it is difficult for manual operation to be safe. Tool changing needs to be carried out after the tool cools down, resulting in low overall processing efficiency. And during the processing, manual monitoring of the processing quality and the tool is required, so manual close observation is also needed, which is extremely likely to cause the drawback of chip flying out and injuring people, and the observation cannot be carried out in real time, and the processing quality and tool wear condition cannot be accurately controlled and observed.

[0005] Therefore, it is necessary to develop a gantry milling machine for manufacturing high-nickel-chromium-molybdenum centrifugally composite rolls to solve the above problems. Summary of the Invention

The running position of the third electric slide rail 101 is controlled by the position of the horizontal electric slide rail for milling 92. The running position of the fourth electric slide rail 103 is controlled by the position of the vertical electric slide rail for milling 91.

[0034] As shown Figure 8 in FIG. 1, the fixing device 11 includes a fixing frame 111 and a second electric push rod 112. The number of the fixing frames 111 is two groups. The fixing frames 111 are respectively fixedly connected to the front and rear sides of the upper right side of the mounting frame 6. The fixing frames 111 are both of a U-shaped sleeve structure with an opening in the left-right direction. The U-shaped sleeve structures of the fixing frames 111 are the same as those of the assembly frame 104. The second electric push rods 112 are installed on the upper sides of the U-shaped sleeve structures of the fixing frames 111. The second electric push rods 112 are vertically arranged.

[0036] Embodiment 2, as shown Figures 10-11As shown, it further includes an inspection device 13. The inspection device 13 includes a second transfer rack 131, a second fitting plate 132, a camera 133, and a collection assembly 14. The inspection device 13 is disposed at the rear side fixing rack 111. The inspection device 13 is detachably arranged at the rear side fixing rack 111 and can be loaded and unloaded and transferred between the assembly rack 104 and the rear side fixing rack 111. The inspection device 13 is used to monitor the working state of the milling cutter 95 during the milling of the workpiece, and can analyze the wear of the milling cutter 95 and the milling quality during the milling process through video output. The second transfer rack 131 is disposed at the right side position of the rear side fixing rack 111. The upper and lower sides of the front and rear walls of the second transfer rack 131 are fixedly connected with second fitting plates 132. The lower second fitting plate 132 is matched with the U-shaped sleeve structure of the rear side fixing rack 111. The second transfer rack 131 is assembled at the U-shaped sleeve structure of the rear side fixing rack 111 through the lower second fitting plate 132. The upper second fitting plate 132 has a matching relationship with the U-shaped sleeve structure of the assembly rack 104. The middle parts of the second fitting plates 132 are all structures with positioning holes. The positioning hole structures of the second fitting plates 132 are used to allow the moving parts of the second electric push rod 112 at the rear side fixing rack 111 and the first electric push rod 105 at the assembly rack 104 to extend for position fixing. A camera 133 is fixedly connected to the lower side of the second transfer rack 131. The camera 133 is used to monitor the operation of the milling cutter 95 in real time. The camera 133 can be switched to a high-speed imaging mode so that the camera 133 can monitor the operation state of the milling cutter 95 in a slow-motion state. A collection assembly 14 is disposed below the second transfer rack 131. The collection assembly 14 is used to collect the chips generated during a certain processing time period and transfer them. The chips generated during a certain processing time period collected can be analyzed to judge the processing states of the workpiece and the milling cutter 95.

[0037] As Figures 10-11As shown in the figure, the collection component 14 includes an extension frame 141, a moving pair 142, an elastic member 143, an outward expansion frame 144, a second electro-suction magnet 145, an air outlet pipe 146, rubber balls 147, a high-pressure air pump 148, and a connecting pipe 149. The extension frame 141 is fixedly connected to the lower side of the second transfer frame 131. The lower side of the extension frame 141 is fixedly connected with a moving pair 142. The moving pair 142 is a vertically arranged guiding pair. An elastic member 143 is fixedly connected to the moving pair 142. The elastic member 143 is a spring. The moving member of the moving pair 142 is acted upon by the elastic member 143. The lower side of the moving member of the moving pair 142 is fixedly connected with an outward expansion frame 144. The outward expansion frame 144 is in an expanded posture towards the right side. A plurality of second electro-suction magnets 145 are fixedly connected to the right side surface of the outward expansion frame 144. The second electro-suction magnets 145 are used to adsorb chips. Three air outlet pipes 146 are fixedly connected to the outward expansion frame 144. The air outlet pipes 146 extend out of the right side of the outward expansion frame 144. Rubber balls 147 are evenly distributed on the lower side surface of the outward expansion frame 144. The rubber balls 147 can enable the outward expansion frame 144 to slide relatively when it comes into contact with the workpiece, avoiding the direct contact between the outward expansion frame 144 and the workpiece and causing local surface scratches on the workpiece. A high-pressure air pump 148 is installed at the upper side position inside the second transfer frame 131. The air outlet end of the high-pressure air pump 148 is fixedly connected with a connecting pipe 149. The other end of the connecting pipe 149 is connected and communicated with the three air outlet pipes 146. Starting the high-pressure air pump 148 can cause high-pressure air flow to be discharged from the air outlet pipes 146 through the connecting pipe 149, enabling the outward expansion frame 144 to blow out the chips within the adsorption range of the second electro-suction magnets 145 through the air outlet pipes 146. Until it is necessary to collect the chips of another processing period, the high-pressure air pump 148 can be turned off, and the second electro-suction magnets 145 can be started to adsorb and collect the chips of this processing period.

[0038] As Figure 5 shown, it further includes a temperature sensor 15. The temperature sensor 15 is fixedly connected to the upper side of the extension base 106. The temperature sensor 15 is obliquely arranged in the lower right direction. The temperature sensor 15 is an infrared temperature measurement probe sensor. By controlling the position of the assembly frame 104, the temperature sensor 15 emits infrared rays to the milling cutter 95 or the processing area, and receives the returned infrared signal to detect the real-time temperature in the milling cutter 95 or the processing area.

[0039] Example 3, as Figures 1-11As shown in the figure, the assembly and milling methods of the gantry milling machine for manufacturing high-nickel chromium molybdenum centrifugal composite rolls for workpieces are as follows: According to the workpiece size, select the assembly base 7 and the clamping frame 8 suitable for the workpiece size, and adjust the position of the assembly base 7 in the installation groove of the base 1 according to the workpiece size. Subsequently, hoist the workpiece on the upper side of the assembly base 7 and adjust its position. Then, fix the clamping frame 8 on the upper side of the assembly base 7 to fix the workpiece. After that, select a suitable milling cutter 95 according to the hardness of the workpiece and perform tool setting. Set the numerical control program according to the processing requirements to set the running paths of the first electric slide rail 2, the vertical milling electric slide rail 91, and the horizontal milling electric slide rail 92 to control the milling method and the feed rate, and set the rotational speed of the milling main unit 93 in a certain milling program. Then, the workpiece can be milled through the first electric slide rail 2 and the milling device 9. Since the mechanical properties of high-nickel chromium molybdenum centrifugal composite rolls are high hardness, high wear resistance, and high thermal crack resistance, and the volume is relatively large, the processing performance of high-nickel chromium molybdenum centrifugal composite rolls is relatively low. During milling, the tool wear is large, and the milling cutter 95 needs to be replaced frequently.

[0040] The method of automatic tool change for the gantry milling machine used to manufacture high-nickel chromium molybdenum centrifugal composite rolls is as follows: ① Position the new milling cutter 95: When the tool hanging rack 124 is assembled at the front fixing rack 111, the tool hanging groove structure of the tool hanging rack 124 faces left at this time. At this time, the new milling cutter 95 can be placed in the rear tool hanging groove of the tool hanging rack 124. The front tool hanging groove structure of the tool hanging rack 124 is used to replace the worn milling cutter 95.
