Technical Field
[0001] This invention relates to the field of metal cutting machine tool technology, specifically to a metal cutting machine tool based on a rotary disc cutter. Background Technology
[0002] In the metal processing industry, metal bars serve as the basic processing blanks. Their slitting is a crucial preliminary process for the subsequent forming of parts, and it has strict requirements for processing accuracy, production efficiency, and finished product quality. Currently, most cutting machine tools used for slitting metal bars on the market adopt traditional structural designs. Among them, the feeding mechanism is mostly a simple manual push type or a single cylinder driven intermittent feeding structure. Usually, manual assistance is required to push the metal bar to the cutting station, or the cylinder pushes a certain distance at a time and then stops the machine to wait for cutting. The cutting mechanism adopts a single-tool design, that is, only one disc tool is fixed on the rotating shaft, which can only perform single-tool segment cutting, resulting in low processing efficiency.
[0003] The core drawback of existing metal bar cutting machine tools is that they generally adopt a single-tool-position segmented cutting mode, and the accompanying feeding and clamping structures are mostly single-limit designs, which can only achieve radial or axial limitation of the metal bar. Single-tool-position segmented cutting requires multiple positioning and cutting operations on a single metal bar, which not only significantly extends the processing cycle of a single bar, but also makes the bar prone to radial runout or axial movement during multiple positioning processes. This results in uneven cutting surfaces, excessive deviations in the dimensions of each segment of the finished product, affects the subsequent processing accuracy, and increases the scrap rate. At the same time, the single-tool-position cutting mode requires a separate multi-positioning and guiding structure to cooperate with multi-round cutting. This leads to the fact that the feeding components, guiding and limiting components and cutting components of existing machine tools are mostly designed as separate units. This increases the number of parts in the whole machine, makes the structure loose, and has a high space occupation rate. At the same time, the fit errors between the parts will continue to accumulate. Combined with the drawbacks of single-tool-position multi-positioning, this further amplifies the processing errors, making it difficult to improve the accuracy of the finished product.
[0004] In response to the core problems of single-tool segmented cutting in the existing technology, such as low processing efficiency, large positioning errors, and process connection bottlenecks, as well as the additional problems such as inaccurate limit positioning, structural interference, poor loading and unloading, high maintenance costs, and low automation, there is an urgent need for a metal cutting machine tool with a reasonable structural design, which can achieve full-process automation through pure mechanical linkage and can replace single-tool segmented cutting with multi-tool synchronous cutting, so as to effectively solve the above-mentioned problems and meet the actual processing needs of batch cutting of metal bars. Summary of the Invention
[0005] The purpose of this invention is to provide a metal cutting machine tool based on a rotary disc cutter to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a metal cutting machine tool based on a rotary disc cutter, comprising a clamping and feeding assembly, wherein the clamping and feeding assembly includes a shaft frame disposed at both ends, a rotary motor is bolted to the outer side of the shaft frame, and a spindle is fixedly connected to the rotating end of the rotary motor, the spindle is rotatably mounted between the two shaft frames, and a feeding cam is coaxially fixed to the outer periphery of the spindle, the feeding cam has several clearance notches radially opened along the axial direction, and a material groove is concavely opened on the outer periphery of the feeding cam, and torsion spring shafts are arranged at both ends of the outer periphery of the feeding cam, and radial baffles are rotatably mounted inside the torsion spring shafts.
[0007] Furthermore, the material groove is recessed on the outer periphery of the feeding cam, and the end opening of the material groove is located at both ends of the feeding cam axis, and the side opening of the material groove is located inside the radial baffle.
[0008] Furthermore, axial retaining rings are provided at both ends of the spindle axis, and the axial retaining rings are located between the gaps between the two end brackets and the opposite end faces of the feeding cam. The axial retaining rings are located outside the opening at the end of the material trough, and the radial baffles are provided with through holes on both sides that cooperate with the axial retaining rings.
[0009] Furthermore, a connecting rib is fixedly connected to the inner wall of the side end of the axial retaining ring, and a mounting ring is fixedly connected to the end of the connecting rib away from the axial retaining ring. The inner diameter of the hole in the mounting ring is larger than the outer diameter of the mandrel, and the mounting ring is fixedly installed on the inner opposite surfaces of the two end shaft brackets.
[0010] Furthermore, the shaft bracket is fixedly installed on the outer side of the left end of the side plate, and a stepper motor is fixedly installed on the outer side of the right end of the side plate. The stepper motor is connected to the conveyor belt between the two side plates for rotational transmission, and the conveyor belt is located below the feeding cam.
[0011] Furthermore, a bracket is fixedly installed in the middle of the side plate, and a hopper is fixedly installed at the top of the bracket. The bottom opening of the hopper is lower than the height of the radial baffle. Several metal bars are vertically stacked inside the hopper. When the feeding cam rotates to the top loading position, the metal bars fall from the bottom opening of the hopper into the clearance notch provided on the outer periphery of the feeding cam.
[0012] Furthermore, a guide plate is fixedly installed on the left end face of the side plate, and the end of the inner arc surface of the guide plate is directly opposite the initial end of the conveyor belt.
[0013] Furthermore, an installation sleeve is fixedly installed on the inner side of the left end of the side plate, and a spring rod is axially raised and lowered inside the installation sleeve. A release pin is fixedly connected to the top of the spring rod, and the release pin pushes the radial baffle to release the metal bar when the feeding cam rotates to the bottom unloading position.
[0014] Furthermore, the side plate is fixedly installed at one end of the base, and a cutting motor is fixedly installed at the bottom of the other end of the base.
[0015] Furthermore, a protective cover is fixedly installed on the top of the other end of the base, and a rotating shaft is rotatably installed inside the protective cover. The pulley at the end of the rotating shaft is connected to the cutting motor for rotational transmission via a synchronous belt. Several disc cutters are fixed radially along the axial direction in the middle of the rotating shaft, and the disc cutters are positioned corresponding to the clearance notches. When the feeding cam rotates to the side cutting position, the disc cutters enter through the clearance notches to achieve the slitting process of the metal bar.
[0016] This invention provides a metal cutting machine tool based on a rotary disc cutter, which has the following beneficial effects; 1. This machine tool uses the clamping and feeding assembly as the core transmission and execution unit, in conjunction with the automatic feeding bin, the disc cutter cutting assembly, and the unloading conveyor assembly. Through mechanical linkage, it realizes the automated cyclic cutting of metal bars. All components work together to follow the work process of automatic feeding, clamping and limiting, precise cutting, automatic unloading, and reset. Compared with traditional cutting equipment, it has significant advantages in terms of processing accuracy, work efficiency, finished product quality, equipment stability, and ease of operation.
[0017] 2. This application uses a torsion spring shaft to drive a radial baffle to form a radial rigid clamp on the bar stock in the feed trough, preventing the bar stock from falling or radially jumping during rotation and cutting. The axial retaining ring simultaneously realizes the axial limit of the bar stock and the rotational guidance of the feeding cam and the radial baffle, avoiding axial movement of the bar stock during cutting. The double limit ensures the positional stability of the bar stock during cutting, effectively improving the flatness of the cutting surface, the consistency of the finished product dimensions of each section, and reducing processing errors.
[0018] 3. The avoidance notch on the feeding cam of this application is precisely matched with the position of the disc cutter. During cutting, the cutter can enter the cutting area through the notch, which not only ensures the effective cutting stroke of the cutter, but also completely avoids hard collision between the cutter and the feeding cam, thus improving the safety of the cutting process. It can achieve multi-segment synchronous cutting of metal bars in one go. Compared with the traditional single-blade segment cutting, it significantly shortens the processing cycle of a single bar. At the same time, the single material groove achieves seamless connection of feeding, cutting and unloading as the feeding cam rotates, which can continuously process metal bars in batches, further improving the overall production efficiency.
[0019] 4. In the feeding stage, this application relies on the self-weight of the stacked bars in the hopper to achieve automatic unloading. Combined with the structural adaptability of the trough and the positional limitation of the radial baffle, it achieves precise feeding of metal bars. In the unloading stage, the release pin mechanically triggers the radial baffle to open and release the bars. Combined with the guide plate with the inner arc surface design, it precisely guides the finished bars, so that the slit bars fall smoothly to the conveyor belt, realizing automatic unloading of the processed products. The degree of automation is higher and the overall production efficiency is effectively improved. Attached Figure Description

[0022] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention. Please see Figures 1 to 7 This invention provides a technical solution: a metal cutting machine tool based on a rotary disc cutter, including a clamping and feeding assembly 1. The clamping and feeding assembly 1 includes a shaft frame 101 disposed at both ends. A rotary motor 102 is bolted to the outer side of the shaft frame 101, and a spindle 103 is fixedly connected to the rotating end of the rotary motor 102. The spindle 103 is rotatably installed between the two shaft frames 101. A feeding cam 104 is coaxially fixed to the outer periphery of the spindle 103. The feeding cam 104 has several clearance notches 105 radially opened along the axial direction. A material groove 106 is recessed in the outer periphery of the feeding cam 104. Torsion spring shafts 107 are arranged at both ends of the outer periphery of the feeding cam 104. A radial baffle 108 is rotatably installed inside the torsion spring shaft 107. The material groove 106 is recessed in the outer periphery of the feeding cam 104. The end opening of the material groove 106 is located at both ends of the axis of the feeding cam 104, and the side opening of the material groove 106 is located inside the radial baffle 108. The specific operation is as follows: During the feeding stage, the rotary motor 102 starts and drives the feeding cam 104 to rotate through the spindle 103. When the feeding cam 104 rotates to the top feeding position, because the height of the bottom opening of the hopper 9 is lower than the height of the radial baffle 108, the radial baffle 108 cannot rotate to the bottom of the hopper 9, so the side opening of the trough 106 naturally opens. The metal rods 10 stacked vertically in the hopper 9 fall into the trough 106 around the feeding cam 104 from the bottom opening by their own weight, thus completing the automatic feeding. Please see Figures 6 to 7 Axial retaining rings 2 are provided at both ends of the spindle 103 axis, and the axial retaining rings 2 are located between the gaps between the two end shaft supports 101 and the opposite end faces of the feeding cam 104. The axial retaining rings 2 are located outside the opening at the end of the material groove 106. The radial baffle 108 has through holes on both sides that cooperate with the axial retaining rings 2. A connecting rib 3 is fixedly connected to the inner wall of the side end of the axial retaining ring 2. A mounting ring 4 is fixedly connected to the end of the connecting rib 3 away from the axial retaining ring 2. The inner diameter of the hole in the mounting ring 4 is larger than the outer diameter of the spindle 103. The mounting ring 4 is fixedly installed on the inner opposite faces of the two end shaft supports 101. The specific operation is as follows: During the clamping and guiding limiting stage, after the feeding cam 104 completes the feeding and leaves the feeding station, the radial baffle 108 closes under the elastic reset action of the torsion spring shaft 107. Its inner clamping block forms a radial clamping effect on the metal bar 10 in the material groove 106, preventing the bar from falling off as the feeding cam 104 rotates. At the same time, the axial retaining ring 2 fixed to the inner side of the two end shaft brackets 101 is located between the shaft brackets 101 and the opposite end faces of the feeding cam 104, which not only provides precise rotational guidance for the rotating feeding cam 104 and the radial baffle 108, but also provides precise rotational guidance for the material groove. The metal bar 10 in the groove 106 forms an axial limit to prevent the bar from moving axially in subsequent processes. In this application, the radial baffle 108 is driven by the torsion spring shaft 107 to form a radial rigid clamp on the bar in the groove 106, preventing the bar from falling or moving radially during rotation and cutting. The axial retaining ring 2 simultaneously realizes the axial limit of the bar and the rotational guidance of the feeding cam 104 and the radial baffle 108, preventing the bar from moving axially during cutting. The double limit ensures the positional stability of the bar during cutting, effectively improves the flatness of the cutting surface, the consistency of the finished product size of each section, and reduces processing errors. Please see Figures 4 to 5A shaft bracket 101 is fixedly installed on the outer side of the left end of the side plate 5, and a stepper motor 6 is fixedly installed on the outer side of the right end of the side plate 5. The stepper motor 6 is rotatably connected to the conveyor belt 7 between the two side plates 5. The conveyor belt 7 is located below the feeding cam 104. A bracket 8 is fixedly installed in the middle of the side plate 5, and a hopper 9 is fixedly installed at the top of the bracket 8. The bottom opening of the hopper 9 is lower than the height of the radial baffle 108. Several metal bars 10 are vertically stacked inside the hopper 9. When the feeding cam 104 rotates to the top loading position, the metal bars 10 are loaded. The material 10 falls from the bottom opening of the hopper 9 into the clearance notch 105 on the outer periphery of the feeding cam 104. A guide plate 11 is fixedly installed on the left end face of the side plate 5, and the end of the inner arc surface of the guide plate 11 is directly facing the initial end of the conveyor belt 7. An installation sleeve 12 is fixedly installed on the inner side of the left end of the side plate 5, and a spring rod 13 is axially raised and lowered inside the installation sleeve 12. A release pin 14 is fixedly connected to the top of the spring rod 13. When the feeding cam 104 rotates to the bottom unloading position, the release pin 14 pushes the radial baffle 108 to release the metal rod 10. The specific operation is as follows: In the automatic feeding stage, after the single metal bar 10 is cut into multiple segments, the feeding cam 104 continues to rotate in the reverse direction to the bottom feeding position. The release pin 14 on the inner side of the left end of the side plate 5 is triggered as the cam rotates. During the return stroke, it moves the radial baffle 108 to open, releasing the radial clamping of the multiple finished bar segments after cutting in the trough 106 and achieving release. The multiple finished bar segments fall by their own weight and are precisely guided by the inner arc surface of the guide plate 11 on the side plate 5, falling smoothly into the initial end of the conveyor belt 7. The stepper motor 6 drives the conveyor belt 7 to rotate, completing the automatic conveying of the finished bar segments. The arc-shaped guide design avoids material collision and damage. In the feeding stage, the material bar 10 is automatically unloaded by relying on the weight of the stacked bars in the hopper 9. With the structural adaptability of the trough 106 and the position restriction of the radial baffle 108, the metal bar 10 is accurately fed. In the unloading stage, the radial baffle 108 is opened by mechanically triggering the release pin 14 to release the bar. With the guide plate 11 with the inner arc surface design, the finished bar is accurately guided, so that the slit bar falls smoothly to the conveyor belt 7, realizing automatic unloading after product processing. The degree of automation is higher, and the overall production efficiency is further improved. Please see Figures 1 to 3 The side plate 5 is fixedly installed at one end of the base 15, and the cutting motor 16 is fixedly installed at the bottom of the other end of the base 15. The protective cover 17 is fixedly installed at the top of the other end of the base 15, and the rotating shaft 18 is rotatably installed inside the protective cover 17. The pulley at the end of the rotating shaft 18 is connected to the cutting motor 16 for rotational transmission through a synchronous belt. Several disc cutters 19 are fixed radially along the axial direction in the middle of the rotating shaft 18. The disc cutters 19 are corresponding to the positions set by the clearance notch 105. When the feeding cam 104 rotates to the side cutting position, the disc cutters 19 enter through the clearance notch 105 to realize the slitting process of the metal bar 10. The specific operation is as follows: During the slitting process, when the feeding cam 104 rotates in reverse to the side cutting position, the several clearance notches 105 on the feeding cam 104 are precisely aligned with the disc cutters 19 of the cutting assembly. At this time, the cutting motor 16 drives the rotating shaft 18 to rotate via the synchronous belt. The several disc cutters 19 arranged radially along the axis on the rotating shaft 18 enter the material groove 106 area through the clearance notches 105, and perform multi-station synchronous slitting processing on the metal bar 10 that is radially clamped and axially limited. The clearance notches 105 effectively prevent structural interference between the cutter and the feeding cam 104. The clearance notch 105 on the wheel 104 is precisely matched with the position of the disc cutter 19. During cutting, the cutter can enter the cutting area through the notch, which not only ensures the effective cutting stroke of the cutter, but also completely avoids hard collision between the cutter and the feed cam 104, thus improving the safety of the cutting process. It can achieve multi-segment synchronous cutting of metal bar 10 in one go. Compared with the traditional single-tool segment cutting, it significantly shortens the processing cycle of a single bar. At the same time, the single material groove 106 rotates with the feed cam 104 to achieve seamless connection of feeding, cutting and unloading, which can continuously process metal bar 10 in batches, effectively improving the overall production efficiency.
[0023] In summary, this machine tool uses the clamping and feeding assembly 1 as the core transmission and execution unit, in conjunction with the automatic feeding bin 9, the disc cutter cutting assembly, and the unloading and conveying assembly, to achieve automated cyclic cutting of metal bars 10 through mechanical linkage. All components work together to follow a cyclical operation process of automatic feeding, clamping and limiting, precise cutting, automatic unloading, and reset. Compared with traditional cutting equipment, it has significant advantages in processing accuracy, operating efficiency, finished product quality, equipment stability, and ease of operation, as detailed below: During the feeding stage, the rotary motor 102 starts and drives the feeding cam 104 to rotate through the spindle 103. When the feeding cam 104 rotates to the top feeding position, the radial baffle 108 cannot rotate to the bottom of the hopper 9 because the height of the bottom opening of the hopper 9 is lower than the height of the radial baffle 108. This causes the side opening of the trough 106 to open naturally, and the metal bars 10 stacked vertically in the hopper 9 fall into the trough 106 around the feeding cam 104 from the bottom opening by their own weight, thus completing the automatic feeding. During the clamping and guiding limiting stage, after the feeding cam 104 completes the feeding and leaves the feeding station, the radial baffle 108 closes under the elastic reset action of the torsion spring shaft 107. Its inner clamping block forms a radial clamp on the metal bar 10 in the material groove 106, preventing the bar from falling off as the feeding cam 104 rotates. At the same time, the axial retaining ring 2 fixed to the inner side of the two end shaft brackets 101 is located between the shaft brackets 101 and the opposite end faces of the feeding cam 104, which not only provides precise rotational guidance for the rotating feeding cam 104 and the radial baffle 108, but also provides precise rotational guidance for the metal bar 10 in the material groove 106. The metal bar 10 is axially limited to prevent axial movement of the bar in subsequent processes. In this application, the radial baffle 108 is driven by the torsion spring shaft 107 to form a radial rigid clamp on the bar in the feed groove 106, preventing the bar from falling and radially jumping during rotation and cutting. The axial retaining ring 2 simultaneously realizes the axial limitation of the bar and the rotation guidance of the feeding cam 104 and the radial baffle 108, preventing axial movement of the bar during cutting. The double limitation ensures the positional stability of the bar during cutting, effectively improves the flatness of the cutting surface, the consistency of the finished product size of each section, and reduces processing errors. During the slitting process, when the feeding cam 104 rotates in reverse to the side cutting position, the several clearance notches 105 on the feeding cam 104 are precisely aligned with the disc cutters 19 of the cutting assembly. At this time, the cutting motor 16 drives the rotating shaft 18 to rotate via a synchronous belt. The several disc cutters 19 arranged radially along the axis on the rotating shaft 18 enter the material groove 106 area through the clearance notches 105, performing multi-station synchronous slitting on the radially clamped and axially limited metal bar 10. The clearance notches 105 effectively prevent structural interference between the cutters and the feeding cam 104. The feeding cam 10 of this application... The clearance notch 105 on the 4 is precisely matched with the position of the disc cutter 19. During cutting, the cutter can enter the cutting area through the notch, which not only ensures the effective cutting stroke of the cutter, but also completely avoids hard collision between the cutter and the feed cam 104, improving the safety of the cutting process. It can achieve multi-segment synchronous cutting of metal bar 10 in one go. Compared with the traditional single-blade segment cutting, it greatly shortens the processing cycle of a single bar. At the same time, the single material groove 106 rotates with the feed cam 104 to achieve seamless connection of loading, cutting and unloading, which can continuously process metal bar 10 in batches, effectively improving the overall production efficiency. In the automatic feeding stage, after the single metal bar 10 is cut into multiple segments, the feeding cam 104 continues to rotate in the reverse direction to the bottom feeding position. The release pin 14 on the inner side of the left end of the side plate 5 is triggered as the cam rotates, and during the return stroke, it moves the radial baffle 108 to open, releasing the radial clamping of the multiple finished bar segments cut in the trough 106 and achieving release. The multiple finished bar segments fall by their own weight and are precisely guided by the inner arc surface of the guide plate 11 on the side plate 5, falling smoothly into the initial end of the conveyor belt 7. The stepper motor 6 drives the conveyor belt 7 to rotate, completing the automatic conveying of the finished bar segments. The material design avoids material collision damage. In the feeding stage, the material bar stacked in the hopper 9 is automatically unloaded by its own weight. With the structural adaptability of the trough 106 and the position restriction of the radial baffle 108, the metal bar 10 is accurately fed. In the unloading stage, the radial baffle 108 is opened by mechanically triggering the release pin 14 to release the bar. With the guide plate 11 with the inner arc surface design, the finished bar is accurately guided, so that the slit bar falls smoothly to the conveyor belt 7, realizing automatic unloading after product processing. The degree of automation is higher, and the overall production efficiency is further improved. During the reset cycle, after all the finished bars in the feed trough 106 have been fed, the feeding cam 104 rotates forward to reset, and the radial baffle 108 closes again to the clamping state under the elastic action of the torsion spring shaft 107. The feed trough 106 on the outer periphery of the feeding cam 104 returns to the top loading position as it rotates, and the entire clamping and feeding assembly 1 returns to the loading state, entering the automated cutting cycle of the next metal bar 10, realizing the processing of single bars sequentially and in batches.
