Description

Technical Field

[0001] The present technical solution relates to the technical field of sphere processing equipment, specifically an efficient ball peeling machine and a processing technology for the ball core of a ball valve. Background Art

[0002] Currently, the processing of the ball core inside a ball valve usually requires multiple processes to gradually process a cylindrical pipe fitting into a ball core. The existing processing technology generally uses multiple devices to correspond to each process respectively for processing. For example, processes such as drilling the inner hole, turning the outer circle, and opening the groove are all completed by independent devices.

[0003] This traditional processing method has many defects: 1. The labor cost is high. Since at least one operator is required for each device, the labor input is large and the cost remains high.

[0004] 2. It occupies a large area. The layout requirement of at least three devices requires a large space for the production site, and the purchase cost of each device is high.

[0005] 3. The processing accuracy is low. Since it is currently necessary for workers to move materials between different devices for loading and unloading, it is difficult to ensure the accuracy of the loading position of each manual loading, resulting in uneven product quality.

[0006] 4. The production efficiency is low. Multiple devices operate independently and rely on manual material movement. There is a waiting time for the connection of processes. At the same time, the manual operation efficiency is limited, and it is difficult to achieve continuous and efficient production, resulting in a long overall processing cycle and being unable to meet the rapid delivery requirements of large - batch orders.

[0007] 5. The spindle speed of the existing turning equipment is relatively low, and it is difficult to drive the material to rotate at a high speed. When the turning equipment performs the outer - circle turning operation on the material, it is difficult to accurately control the cutting force and accuracy; due to insufficient speed, the flatness of the material surface after turning is not good. Even with a finishing turning tool, it is impossible to effectively eliminate the surface processing marks and difficult to form a mirror effect; moreover, the low - speed processing efficiency is low and cannot meet the production requirements of high precision and high quality.

[0008] 6. In the traditional outer - circle turning operation, multiple processes need to be completed in stages by multiple devices: first, a device is used to turn the material into a spherical shape, and then another device is used to polish the surface to achieve a mirror effect; this mode not only requires frequent equipment replacement, inconvenient operation, long processing cycle, and low production efficiency, but also is prone to positioning errors when the material is transferred between devices, directly affecting the turning accuracy and surface quality. Summary of the Invention

[0009] The purpose of this technical solution is to provide an efficient ball peeling machine and a processing technology for the ball core of a ball valve. By integrating multiple processing procedures such as drilling the inner hole, turning the outer circle, and grooving into one, and realizing sequential feeding and discharging through a material transfer device, precise and continuous processing of materials between different procedures is achieved, improving the problems of high labor cost, large equipment floor area, low processing accuracy, and low production efficiency in the processing of the ball core of a ball valve.

[0010] The purpose of this technical solution is achieved as follows: An efficient ball peeling machine includes: a frame; a material transfer device installed on the frame for transporting materials to a set position; a fixed reference device installed on the frame for performing cutting operations on the central hole and the lower half of the materials transported by the material transfer device; a turning device installed on the frame and located beside the fixed reference device for performing turning operations on the materials transported from the fixed reference device to form a spherical structure of the materials; a milling device installed on the frame and located beside the turning device for performing milling operations on the side walls of the materials transported from the turning device to form grooves on the side walls of the materials; the material transfer device sequentially feeds the materials to the fixed reference device, moves them to the turning device and the milling device, and finally discharges them from the milling device.

[0011] The above technical solution integrates the core processes such as drilling the inner hole, turning the outer circle, and grooving of the ball core of a ball valve. Through the collaborative operation of the fixed reference device, turning device, and milling device on the frame, and the material transfer device completes automatic feeding and discharging between processes, reducing labor input and site occupation, improving the consistency of product quality, realizing efficient, continuous, and precise processing of the ball core of a ball valve, and effectively ensuring the double improvement of production efficiency and quality.

[0012] Preferably, the material transfer device includes a number of clamping mechanisms that can move horizontally and vertically on the frame; the clamping component of the clamping mechanism has a clamping position for clamping materials; the fixed reference device includes a fixed reference clamping mechanism and a cutting mechanism, and the fixed reference clamping mechanism has a fixed reference clamping position; the turning device includes a turning clamping mechanism and a turning mechanism, and the turning clamping mechanism has a turning clamping position; the milling device includes a milling clamping mechanism and a milling mechanism, and the milling clamping mechanism has a milling clamping position; the vertical plane where the center of the clamping position corresponds to the centers of the fixed reference clamping position, turning clamping position, and milling clamping position is a coplanar relationship.

[0013] In the above technical solution, the vertical plane where the center of the material clamping position corresponds to the centers of the fixed reference clamping position, the turning clamping position, and the milling clamping position is a coplanar relationship, realizing the movement of the material within the material clamping position and placing it in the corresponding clamping position, improving the accuracy of the material transfer device in transporting the material, ensuring the position accuracy of the material moving into different processing stations, and thus ensuring the precise and continuous processing of the material between different processes.

[0014] Preferably, a plurality of material clamping mechanisms are respectively installed above the corresponding fixed reference clamping position, turning clamping position, and milling clamping position; the fixed reference clamping mechanism is horizontally installed on the frame, the cutting mechanism is vertically installed on the frame, and the cutting mechanism is located below the fixed reference clamping position; the turning mechanism is horizontally installed on the frame and beside the fixed reference clamping mechanism, the turning clamping mechanism is vertically installed on the frame and beside the cutting mechanism, and the turning mechanism is located behind the turning clamping position; the milling clamping mechanism is horizontally installed on the frame and beside the turning mechanism, the milling mechanism is vertically installed on the frame and beside the turning clamping mechanism, and the milling mechanism is located in front of the milling clamping position.

[0015] In the above technical solution, the material clamping mechanism is installed above the corresponding fixed reference clamping position, turning clamping position, and milling clamping position, the fixed reference clamping mechanism, the turning mechanism, and the milling clamping mechanism are horizontally installed on the frame in sequence, and the cutting mechanism, the turning clamping mechanism, and the milling mechanism are vertically installed on the frame in sequence, improving the space utilization rate, making the installation position of each mechanism more compact, reducing the overall volume, and reducing the occupation of space and site.

[0016] Preferably, the cutting mechanism of the fixed reference device includes: a cutting assembly, which is slidably arranged on the frame and used for cutting the material in the fixed reference clamping position of the fixed reference device; a cutting movement assembly, which is installed between the frame and the cutting assembly and used for driving the cutting assembly to longitudinally slide on the frame; the cutting assembly includes a cutting tool, the cutting tool includes a reaming part and a plurality of arc parts, the plurality of arc parts are circumferentially distributed in the lower half of the reaming part, the front end of the reaming part has a reaming edge, the reaming part extends into the central hole of the material, the reaming edge performs reaming operation on the central hole of the material, the arc part has an arc edge, and the arc edge performs cutting on the lower end edge of the central hole of the material and the outer side wall of the lower end of the material.

[0017] The above technical solution of the cutting tool includes a reaming part and several arc parts. The reaming part extends into the central hole of the material. The reaming edge of the reaming part performs reaming operation on the central hole of the material, and the arc edge performs cutting on the lower edge of the central hole of the material and the outer side wall of the lower end of the material. By using the same cutting tool to achieve multiple cutting functions, only by driving the cutting tool to rotate, multiple cutting processes such as reaming, chamfering, and milling the outer circle can be completed, reducing the cutting time, improving the production efficiency, and ensuring the consistency of product processing.

[0018] Preferably, the turning mechanism of the turning device includes: a turning component, which is slidably installed on the frame and is used for turning the surface of the material in the turning clamping position of the turning device; a turning moving component II, which is installed between the frame and the turning component and is used for driving the turning component to approach or move away from the material in the turning clamping position of the turning device; the turning component includes: a swing driving part, which is installed on the turning moving component II; a swing arm, which is installed on the driving end of the swing driving part; a turning tool holder, which is installed on the swing end of the swing arm; a rough turning tool group, which is installed on the turning tool holder; a finish turning tool, which is installed on the turning tool holder and is located beside the rough turning tool group; by switching the positions of the rough turning tool group and the finish turning tool through the turning moving component II, the rough turning tool group and the finish turning tool can perform turning operations on the material in the turning clamping position in sequence; the turning clamping and rotating component of the turning device includes a turning rotating main shaft, and the turning rotating main shaft is a ten-thousand-rpm main shaft.

[0019] The turning rotating main shaft adopts a ten-thousand-rpm main shaft, which drives the material to rotate at a high speed through the high speed, so that the turning component can accurately complete the operation of turning the outer circle; the high speed ensures the turning accuracy of the material surface, and under the action of the finish turning tool, the surface of the material can reach a mirror effect; at the same time, by swinging the swing arm up and down once, the rough turning and finish turning can be completed, without additionally setting a finish turning mechanism, reducing the volume of the machine and saving the occupied space of the site.

[0020] Preferably, the rough turning tool group includes: a rough turning tool I, which is installed on the turning tool holder; a rough turning tool II, which is installed on the turning tool holder, the rough turning tool II is located above the rough turning tool I, and the distance from the front end of the rough turning tool II to the center of the turning clamping position of the turning device is greater than the distance from the front end of the rough turning tool I to the center of the turning clamping position.

[0021] The above technical solution installs the two tools, namely rough turning tool 1 and rough turning tool 2, on the same turning tool rest. Only by lifting the turning tool rest once can rough turning tool 1 and rough turning tool 2 respectively perform turning operations on the surface of the material in sequence. That is, rough turning tool 2 first performs the first turning on the material, and then rough turning tool 1 performs another turning to make the thickness of the turned material reach the set thickness, achieving two turnings of the material. There is no need for an additional turning mechanism to achieve multiple turnings of the material, saving turning time, improving production efficiency, reducing tool wear, and prolonging the service life of the rough turning tool.

[0022] Preferably, the turning device further includes: a chamfering mechanism, which is installed on the frame and is used to chamfer the upper and lower ends of the material in the turning clamping position of the turning device; the chamfering mechanism includes: an upper chamfering tool, which is installed on the turning tool rest of the turning mechanism. The upper chamfering tool is located beside the rough turning tool group and above the finish turning tool, and is used to chamfer the upper end of the material in the turning clamping position; a lower chamfering tool, which is installed on the frame and is used to chamfer the lower end of the material in the turning clamping position.

[0023] When performing an external turning operation on the outer side of the material with the above technical solution, the chamfering mechanism simultaneously chamfers the upper and lower ends of the central hole of the material, eliminating the need for separate processing production at multiple stations, improving production efficiency, ensuring the high-efficiency production of products, and reducing the occupied space of the equipment at the same time.

[0024] Preferably, the turning clamping mechanism of the turning device includes: a turning clamping and rotating assembly, which is slidably arranged on the frame, and a turning clamping position is provided on the turning clamping and rotating assembly for clamping and rotating the material; a positioning assembly, which is installed beside the turning clamping and rotating assembly, and the end of the positioning assembly extends into the turning clamping position for abutting against the lower end of the material in the turning clamping position; a turning moving assembly 1, which is installed on the frame and connects the turning clamping and rotating assembly and the positioning assembly, and is used to drive the turning clamping and rotating assembly and the positioning assembly to slide longitudinally on the frame; the positioning assembly includes: a positioning frame, which is installed on the turning moving assembly 1; a positioning member, which is installed on the positioning frame, and the front end of the positioning member extends into the turning clamping position for abutting against the lower end of the material to limit the longitudinal movement of the material on the turning clamping and rotating assembly.

[0025] With the above technical solution, the front end of the positioning member extends into the turning clamping position, enabling the positioning member to abut against the lower end of the material and restricting the longitudinal movement of the material on the turning clamping and rotating assembly, ensuring the accurate position of the material after loading, thus ensuring the accuracy of external turning processing and the accuracy of each material during processing.

[0026] Preferably, the high-efficiency ball stripping machine further includes: a drilling device, which is installed on the frame and located between the turning device and the milling device, and is used for drilling the side wall of the material transported by the turning device; the drilling device includes: a drilling clamping mechanism, which is installed on the frame, and the drilling clamping mechanism has a drilling clamping position for clamping the material processed by the turning device; a drilling mechanism, which is installed on the frame and is used for drilling the side wall of the material at the drilling clamping position; the drilling clamping mechanism includes: a support seat, which is installed on the frame, and the upper end of the support seat has the drilling clamping position; a pressure plate frame, which is installed at the side end of the support seat; a pressure plate, which is rotatably installed at the upper end of the pressure plate frame and is used to press the material against the upper end of the support seat; a pressure plate driving member, which is installed at the upper end of the pressure plate frame, and the driving end of the pressure plate driving member is connected to the pressure plate and is used to drive the end of the pressure plate to be placed above or leave the drilling clamping position.

[0027] The above technical solution designs a drilling device to drill the side wall of the material, meeting the customer's additional production requirements for the product, improving the product applicability, eliminating the need for an additional separate device for drilling operations, and reducing space occupation.

[0028] A processing technology for a ball valve ball core, used for the high-efficiency ball stripping machine, includes the following steps: Step 1: The material transfer device feeds the material onto the fixed reference device. The fixed reference clamping mechanism of the fixed reference device clamps the material, and the cutting mechanism performs cutting and reaming operations on the lower half of the material. Step 2: The material transfer device takes out the material from the fixed reference clamping mechanism and feeds the material onto the turning device. The positioning component of the turning device abuts against the lower end of the material. The turning clamping and rotating component internally supports and clamps the material. The turning clamping and rotating component rotates the material. The lower chamfering tool abuts against the lower end of the material to perform chamfering operations on the material. The swing arm drives the turning tool holder to swing upward, so that the rough turning tool two performs external turning on the material. At the same time, the rough turning tool one performs external turning on the material again. The swing arm drives the turning tool holder to swing downward, and the finishing tool polishes the outer wall of the material. When the swing arm drives the turning tool holder to swing downward to the set position, the turning tool holder makes the upper chamfering tool abut against the upper end of the material to perform chamfering operations. Step 3: The material transfer device takes out the material from the turning device and feeds the material into the drilling device. The drilling clamping mechanism clamps the material. The pressure plate driving member drives the pressure plate to press the material against the upper end of the support seat. The drilling tool of the drilling mechanism drills the side wall of the material. When the drilling is completed, the pressure plate driving member drives the pressure plate to leave the upper end of the material. Step 4: The material transfer device removes the material at the upper end of the support base and feeds the material into the milling device. The milling clamping mechanism clamps the material and moves it towards the milling mechanism. The milling mechanism performs milling operations on the side wall of the material by rotating the milling cutter. After milling, the milling clamping mechanism moves the material to below the clamping position of the material transfer device. Step 5: The material transfer device removes the material from the milling clamping mechanism and discharges it.

[0029] The prominent and beneficial technical effects of this technical solution compared with the prior art are: 1. This technical solution integrates multiple processing procedures such as drilling the inner hole, turning the outer circle, and grooving of the ball valve ball core. Through the corresponding fixed reference device, turning device, and milling device on the machine frame, the corresponding procedures are processed. At the same time, a material transfer device is configured to achieve sequential feeding and discharging of the corresponding procedures, realizing precise and continuous processing of the material between different procedures, effectively reducing labor input and site occupation, improving the consistency of product processing quality, improving the processing efficiency and quality of the ball valve ball core, and ensuring the high-efficiency production requirements of the ball valve ball core.

[0030] 2. The turning rotating spindle designed in this technical solution is a ten-thousand-rpm spindle. The high-speed turning rotating spindle drives the material to rotate at a high speed, enabling the turning assembly to precisely control the cutting process and improving the machining accuracy of the outer circle turning operation. The high speed, combined with the precision turning tool, can quickly eliminate the machining marks on the surface of the material, making the surface smooth as a mirror. This not only improves the appearance quality and performance of the product but also shortens the processing cycle through the high-speed and efficient processing mode, effectively improving production efficiency and providing a reliable guarantee for the high-precision and high-quality processing of the ball valve ball core.

[0031] 3. The vertical plane where the center of the clamping position corresponds to the centers of the fixed reference clamping position, turning clamping position, and milling clamping position is a coplanar relationship. This realizes the movement and placement of the material in the clamping position, improving the accuracy of the material transfer device in transporting the material and ensuring the position accuracy of the material moving to different processing stations, thus ensuring the precise and continuous processing of the material between different procedures.

[0032] 4. The cutting tool designed in this technical solution includes a reaming part and several arc parts. The reaming part extends into the center hole of the material, and the reaming edge of the reaming part performs reaming operations on the center hole of the material. The arc part has an arc edge, and the arc edge performs cutting on the lower edge of the center hole of the material and the outer side wall of the lower end of the material. By using the same cutting tool to achieve multiple cutting procedures, the cutting time is reduced, the production efficiency is improved, and the consistency of product processing is ensured.

[0033] 5. The turning device designed in this technical solution includes a turning mechanism and a chamfering mechanism. When performing an external turning operation on the outer side of the material, the upper and lower ends of the central hole of the material are chamfered simultaneously through the chamfering mechanism. There is no need to use multiple workstations for separate processing and production, which improves production efficiency, ensures the efficient production of products, and reduces the occupied space of the equipment.

[0034] 6. The drilling device designed in this technical solution is used to drill the side wall of the material, meeting the additional production requirements of customers for the product, improving the applicability of the product, and there is no need to use an additional separate device for drilling operations, reducing space occupation.

[0035] 7. In this technical solution, the material clamping mechanism is installed above the corresponding fixed reference clamping position, turning clamping position, and milling clamping position. The fixed reference clamping mechanism, turning mechanism, and milling clamping mechanism are horizontally installed on the frame in sequence, and the cutting mechanism, turning clamping mechanism, and milling mechanism are vertically installed on the frame in sequence, improving space utilization rate, making the installation position of each mechanism more compact, reducing the overall volume, and reducing the occupation of space and site.

[0074] The turning rotation main shaft 452 adopts a ten-thousand-rpm main shaft, which drives the material to rotate at a super-high speed. The turning mechanism 42 can accurately control the cutting process, greatly improving the machining accuracy of the outer circle turning operation; the high speed is combined with the precision turning tool 485, which can quickly eliminate the machining marks on the surface of the material, making the surface as smooth as a mirror.

[0078] As Figures 6 - 11 , the turning component 48 includes: a swing driving member 481, a swing arm 482, a turning tool holder 483, a rough turning tool group 484 and a finishing tool 485; the swing driving member 481 is a motor or a swing cylinder and is installed on the second turning movement component 49; the swing arm 482 is installed on the driving end of the swing driving member 481; the turning tool holder 483 is installed on the swing end of the swing arm 482; the rough turning tool group 484 is installed on the rough turning tool mounting part 4831 of the turning tool holder 483; the finishing tool 485 is installed on the finishing tool mounting part 4832 of the turning tool holder 483, and the finishing tool 485 is located beside the rough turning tool group 484; by switching the front and back positions of the rough turning tool group 484 and the finishing tool 485 through the second turning movement component 49, the rough turning tool group 484 and the finishing tool 485 sequentially perform turning operations on the material in the turning clamping position 44. First, the swing arm 482 swings upward and the rough turning tool group 484 performs rough turning on the material, then the rough turning tool group 484 and the finishing tool 485 are moved forward through the second turning movement component 49, and then the swing arm 482 swings downward and returns to its original position and the finishing tool 485 performs fine machining on the material, that is, polishing operation. The rough turning tool group 484 performs the first processing on the material, and the finishing tool 485 performs the second processing on the material.

[0079] As Figure 7, the rough turning tool set 484 includes: a first rough turning tool 4841, which is installed on the turning tool rest 483; a second rough turning tool 4842, which is installed on the turning tool rest 483. The second rough turning tool 4842 is located above the first rough turning tool 4841, and the distance from the front end of the second rough turning tool 4842 to the center of the turning clamping position 44 is greater than the distance from the front end of the first rough turning tool 4841 to the center of the turning clamping position 44. So that a part of the outer end of the material is first turned off by the second rough turning tool 4842, making the material into a spherical shape, and then a part of it is further turned off by the first rough turning tool 4841. That is, the second rough turning tool 4842 first reduces the thickness of the material 100 by a set thickness, and then the first rough turning tool 4841 further cuts the thickness of the material 100. Through one upward swing of the swing arm 482, two turning operations are realized. While ensuring the processing efficiency, it avoids serious wear on the tool when directly turning to the set thickness at one time, and extends the service life of the rough turning tool set 484.

[0080] The second turning movement component 49 includes: a second turning driving part 491, which is a motor and is installed on the frame 1; a second turning lead screw, which is rotatably installed on the frame 1 and is connected to the driving end of the second turning driving part 491; a second turning slide 493, which is slidably arranged on the frame 1 and is threadedly connected to the second turning lead screw.

[0081] As Figure 10 And Figure 11 , the chamfering mechanism 43 includes: an upper chamfering tool 431 and a lower chamfering tool 432 which are identical in structure and arranged oppositely; in this embodiment, the upper chamfering tool 431 is installed on the upper chamfering tool installation part 4833 of the turning tool rest 483 of the turning mechanism 42. The upper chamfering tool 431 has a chamfering edge groove 433 for chamfering the opening edge of the central hole 101. The upper chamfering tool 431 is located beside the rough turning tool set 484 and above the finish turning tool 485. When the second turning movement component 49 switches to the finish turning tool 485 to turn the material, and when the swing arm 482 swings downward and resets, the upper chamfering tool 431 abuts against the upper end of the material 100 for chamfering the upper end opening of the central hole 101 of the material 100 in the turning clamping position 44; a lower chamfering tool support 434 is installed on the frame 1.

After the material is placed in the turning clamping position 44, there is a space between the inner wall of the lower end opening of the central hole 101 of the material and the outer side wall of the turning inner support fixture 453 for the front end of the lower chamfering tool 432 to insert, so that the lower end opening edge of the central hole 101 of the material can be placed in the chamfering edge groove 433 of the lower chamfering tool 432.

The braking member is located between the side wall of the chute and the slide rail. A tension spring is arranged between the side wall of the chute and the braking member. An air inlet hole is arranged on the side wall of the chute. Gas is transported into the chute through the air inlet hole. The braking member is pressed against the slide rail by air pressure, so as to prevent the slider from sliding on the slide rail, ensuring that when the milling mechanism 52 performs the milling groove operation, the braking member is used to overcome the reaction force of milling and prevent the movement of the milling fixture 54; when gas is no longer injected into the air inlet hole, the tension spring drives the braking member to disengage from the slide rail, realizing the sliding of the slider on the slide rail.

[0090] The drilling mechanism 62 includes: a drilling assembly 64 and a drilling moving assembly 65; the drilling assembly 64 is slidably installed on the frame 1 in the front and rear directions and is used to perform drilling operations on the rear side wall of the material 100 in the drilling clamping position 63; the drilling moving assembly 65 is a lead screw transmission mechanism, which is installed on the frame 1 and the drilling assembly 64 and is used to drive the drilling assembly 64 to approach or move away from the side wall of the material 100 in the drilling clamping position 63.

The pressure-holding device is connected to the fixed reference device 3, the turning device 4, the drilling device 6, and the milling device 5 through a plurality of pipelines, and is used to provide air pressure or oil-air pressure inside the fixed reference device 3, the turning device 4, the drilling device 6, and the milling device 5, so as to prevent the gaps between various parts from being blocked by the waste materials cut off by the materials, and at the same time ensure the running stability and smoothness between the parts. Specifically, the oil and gas are transported through the pipeline to between the cutting spindle 3212 of the cutting component 321 and the cutting bushing, between the turning rotating spindle 452 of the turning clamping and rotating component 45 and the turning rotating bushing, between the milling spindle 562 of the milling component 56 and the milling bushing, and between the drilling spindle 642 of the drilling component 64 and the drilling bushing by the oil mist lubricator, the air compressor or the air pump.

The oil can lubricate the spindle, and the gas ejected from the gap between the corresponding spindle and the bushing can blow away the chips cut from the materials, preventing the chips from entering the gap and affecting the rotation of the spindle. At the same time, through holes are opened on the clamping component 233, the fixed reference fixture 311, the turning inner support fixture 453, and the milling fixture 54.

[0095] A processing technology for a ball valve ball core, combined with Figures 17 - 19 , based on the structure of the above-mentioned high-efficiency ball peeling machine, realizes the following steps: Step 1: The material transfer device 2 feeds the material 100 onto the fixed reference device 3. The fixed reference clamping mechanism 31 of the fixed reference device 3 clamps the material 100, and the cutting mechanism 32 cuts the lower half of the material 100 into a hemispherical shape and enlarges the central hole 101, so that the material is processed from Figure 19 the D1 state in to the D2 state; Figure 19The D2 state in is processed into the D3 state; when the swing arm 482 drives the turning tool rest 483 to swing downward for resetting, the finish turning tool 485 polishes the outer wall of the material 100. When the swing arm 482 drives the turning tool rest 483 to swing downward to the set position, the turning tool rest 483 makes the upper chamfering tool 431 abut against the upper end of the material 100 and performs chamfering operation, so that the material changes from Figure 19 the D3 state in to the D4 state; Step Three: The material transfer device 2 takes out the material 100 in the turning device 4 and feeds the material into the drilling device 6. The drilling clamping mechanism 61 clamps the material 100, and the pressing drive part 614 drives the pressing part 613 to press the material 100 against the upper end of the support seat 611. The drilling tool of the drilling mechanism 62 approaches and drills the side wall of the material 100, so that a through hole 103 is formed on the side wall of the material, thus making the material change from Figure 19 the D4 state in to the D5 state. After the drilling is completed, the pressing drive part 614 drives the pressing part 613 to leave the upper end of the material 100; Step Four: The material transfer device 2 takes out the material 100 on the upper end of the support seat 611 and feeds the material 100 into the milling device 5.

The milling mechanism 52 performs milling operation on the side wall of the material 100 by rotating the milling tool 563, so that the material changes from Figure 19 the D5 state in to the D6 state. After the milling is completed, the milling clamping mechanism 51 moves the material 100 to the lower part of the material clamping position 24 of the material transfer device 2; Step Five: The material transfer device 2 takes out the material 100 in the milling clamping mechanism 51 and unloads it.
