Description

Technical Field

[0001] This utility model relates to a CNC copying machine. Background Technology

[0002] Some irregularly shaped boards (such as cutting boards and washboards) are processed using CNC profiling machines. However, traditional old-fashioned CNC profiling machines require manual placement of the boards under the profiling cutter and manual positioning. After the profiling cutter finishes processing, the boards are removed manually. This manual loading, positioning, and unloading method has a low degree of automation. Operators need to operate frequently, which not only increases the intensity of manual labor but also takes a long time, affecting the overall production efficiency. Utility Model Content

[0003] This utility model addresses the problems existing in the prior art by providing a CNC copying machine.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a CNC profiling machine, comprising a positioning and feeding mechanism, a clamping mechanism, and a discharging mechanism arranged sequentially from back to front on the machine table. The positioning and feeding mechanism includes a vertically arranged feeding channel, and a pulling mechanism is arranged above the feeding channel to transport several vertically stacked plates into the feeding channel. A feeding component is arranged below the feeding channel to transport the bottommost plate forward to the clamping mechanism. The clamping mechanism is arranged beside the profiling cutter and clamps the plate from both the top and bottom. The discharging mechanism receives and outputs the processed plate pushed out by the feeding component on the clamping mechanism.

[0005] Furthermore, a feeding lifting platform is provided on the left side of the positioning and feeding mechanism for placing multiple vertically stacked boards. The feeding lifting platform lifts several boards upwards to the top of the feeding channel each time. The pulling mechanism is used to push the several boards lifted upwards by the feeding lifting platform to the top of the feeding channel from left to right into the feeding channel.

[0006] Furthermore, the material pulling mechanism includes a vertically arranged material pulling push plate, which is located above the machine platform and is used for contacting the left end faces of several plates. The material pulling push plate is connected to the feeding moving assembly. The feeding moving assembly includes a feeding moving seat located above the front side of the feeding channel. The feeding moving seat is driven by a horizontally arranged feeding cylinder to move left and right along a pair of horizontally arranged feeding guide rods. The material pulling push plate is connected to the feeding moving seat and moves left and right synchronously with the feeding moving seat.

[0007] Furthermore, a pair of longitudinal connecting rods distributed on the left and right are fixed to the rear end of the feeding moving seat, and a pair of transverse connecting rods distributed at intervals in front and behind are fixed to the upper end of the pulling push plate. The pair of transverse connecting rods are located above the pair of longitudinal connecting rods. A connecting block is provided at the intersection of each transverse connecting rod and the pair of longitudinal connecting rods. The upper end of the connecting block is slidably engaged with the transverse connecting rod, and the lower end is slidably engaged with the longitudinal connecting rod. A first sliding locking handle is also provided at the upper and lower ends of the connecting block.

[0008] Furthermore, the feeding assembly includes a feeding seat plate for supporting several vertically stacked plates. The feeding seat plate is provided with a pre-push clamping assembly for pushing and clamping the bottommost plate forward. The feeding seat plate is driven forward by the feeding moving assembly to convey the bottommost plate forward.

[0009] Furthermore, a feeding channel is formed between the top of the feeding seat plate and the bottom of the front end of the feeding channel to facilitate the passage of a single piece of material; a liftable baffle assembly is provided on the front side of the feeding channel, which is used to abut against the front end face of the material pushed forward by the pre-push clamping assembly; the pre-push clamping assembly includes a pre-push moving plate arranged horizontally above the feeding seat plate, which is driven to move back and forth by the pre-push moving assembly arranged on the feeding seat plate; the front end face of the pre-push moving plate is provided with a pair of left and right distributed push blocks for contacting the rear end face of the bottommost material, and the front side of the pair of push blocks is provided with a clamping assembly for clamping the bottommost material from the left and right directions.

[0010] Furthermore, the clamping assembly includes a pair of longitudinal support plates distributed on the left and right sides of the feeding seat plate. The rear ends of the pair of longitudinal support plates are connected to the top of the pre-push moving plate by fasteners. Each longitudinal support plate has an L-shaped clamping block on its inner side. Each L-shaped clamping block is driven to move left and right by a clamping cylinder that is horizontally installed on the longitudinal support plate. The rear end face of the pre-push moving plate is fixed with a pair of longitudinal pushing rods distributed on the left and right. When the bottom plate is pushed forward, the pair of longitudinal pushing rods support the remaining plate in the feeding channel.

[0011] Furthermore, the cross-section of the feeding channel is rectangular, and the length and width of the feeding channel are adjustable. The feeding channel includes a front side plate, a rear side plate, a left side plate, and a right side plate. The front side plate is horizontally arranged, and fixed guide shafts and movable guide shafts are respectively arranged longitudinally at the left and right ends. A first slider is fixed at the front end of the movable guide shaft. The first slider is slidably engaged with a first horizontal groove at the right end of the front side plate. A second slider is slidably connected to the movable guide shaft behind the first slider. The second slider is slidably engaged with a second groove at the top right end of the horizontally arranged rear side plate. The left end of the rear side plate is slidably engaged with the fixed guide shaft through a third slider. The left side plate and the right side plate are a pair and are distributed in front and back. The left side plate at the front end is fixedly connected to the fixed guide shaft, and the left side plate at the rear end is fixedly connected to the rear side plate. The right side plate at the front end is fixedly mounted on the movable guide shaft through a guide shaft support, and the right side plate at the rear end is fixedly connected to the second slider.

[0012] Furthermore, the clamping mechanism includes a horizontally arranged rotating support plate for supporting the plate. The rotating support plate is driven to rotate by a rotating power component located below it. An upper pressure plate is arranged directly above the rotating support plate. The upper pressure plate is driven to move up and down by a clamping drive component. The upper pressure plate is rotatably connected to the moving end of the clamping drive component. The contouring cutter is driven to rotate by a power motor through a transmission component. The power motor, the transmission component, and the contouring cutter are driven to move horizontally and vertically by a two-dimensional moving module.

[0013] Furthermore, the discharge mechanism includes a horizontally arranged conveyor belt for conveying the processed boards from right to left, and a discharge lifting platform is provided on the left side of the conveyor belt for receiving and vertically stacking the processed boards.

[0014] Compared with the prior art, the present invention has the following advantages: The present invention is reasonably designed, the feeding channel is semi-automatic, and the plates in the feeding channel are positioned one by one and then conveyed forward to the clamping mechanism next to the contour cutter. The whole process does not require manual placement, positioning and unloading, which effectively liberates manual operation, reduces the intensity of manual labor, reduces operation time, and thus improves the overall production efficiency.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] like Figures 1-18As shown, this utility model discloses a CNC profiling machine, comprising a positioning and feeding mechanism 200, a clamping mechanism 300, and a discharging mechanism 400 arranged sequentially from back to front on a machine base 101. The positioning and feeding mechanism 201 includes a vertically arranged feeding channel 202, the top and bottom of which are open. A pulling mechanism 104 is arranged above the feeding channel 202, which is used to convey several vertically stacked plates from left to right into the feeding channel 202. The feeding channel 202 is used to accommodate several plates stacked vertically; a feeding assembly 201 is provided below the feeding channel 202 to convey the bottom plate forward to the pressing mechanism; the pressing mechanism 300 is located beside the profile cutter 500 and presses the plate from the top and bottom, and the profile cutter processes the plate pressed by the pressing mechanism; the discharging mechanism 400 is used to receive and output the processed plate pushed out by the feeding assembly 201 when it is fed forward on the pressing mechanism 300.

[0020] In this embodiment, a loading lifting platform 103 for placing multiple vertically stacked boards is provided on the left side of the positioning and feeding mechanism 200. The loading lifting platform 103 is used to place multiple vertically stacked boards, and it lifts several boards upwards to above the loading channel 202 each time. The pulling mechanism 104 is used to push the boards lifted by the loading lifting platform 103 to above the loading channel 202 from left to right into the loading channel 202, thus realizing loading. In use, multiple boards are manually stacked vertically and placed on the loading lifting platform. The loading lifting platform lifts several boards upwards to above the loading channel each time, and then the pulling mechanism pushes several boards from left to right into the loading channel. By lifting the boards with the loading lifting platform and then conveying them to the loading channel with the pulling mechanism, semi-automatic loading into the loading channel is achieved, eliminating the need for frequent manual operation, reducing loading time, and thus improving overall production efficiency.

[0021] In this embodiment, the material pulling mechanism 104 includes a material pulling push plate 105 vertically arranged above the loading lifting platform 103. The material pulling push plate 105 is located above the machine base 101 and is used to contact the left end face of several plates that are lifted upward by the loading lifting platform 103 to the loading channel 202 each time. The material pulling push plate 105 is connected to the loading moving component. The material pulling push plate 105 is driven to move left and right by the loading moving component 106 to realize the conveying of several vertically stacked plates from left to right.

[0022] In this embodiment, the feeding moving assembly 106 includes a feeding moving seat 107 vertically arranged above the front side of the feeding channel 202. The feeding moving seat 107 is driven by a horizontally arranged feeding cylinder 108 to move left and right along a pair of horizontally arranged feeding guide rods 109. The pulling push plate 105 is connected to the feeding moving seat 107 and moves left and right synchronously with the feeding moving seat. Specifically, a pair of left and right longitudinal connecting rods 110 are fixed to the rear end of the feeding moving seat 107. A pair of front and rear spaced transverse connecting rods 111 are fixed to the upper end of the pulling push plate 105. The pair of transverse connecting rods 111 are located above the pair of longitudinal connecting rods 110. A connecting block 112 is provided at the intersection of each transverse connecting rod 111 and the pair of longitudinal connecting rods 110. The upper end of the connecting block 112 is slidably engaged with the transverse connecting rod 111, and the lower end is slidably engaged with the longitudinal connecting rod 110. By having the connecting blocks slide and engage with the horizontal and vertical connecting rods respectively, the position of the material pulling plate can be easily adjusted in the front-back and left-right directions, thereby adapting to different sizes of boards and improving the flexibility of use.

[0023] In this embodiment, to facilitate sliding locking, the upper and lower ends of the connecting block 112 are respectively provided with first sliding locking handles 113. The upper first sliding locking handle 113 is used to lock the left and right movement of the transverse connecting rod 111, and the lower first sliding locking handle 113 is used to lock the forward and backward movement. It should be noted that the first sliding locking handle is an existing mature product. It is threadedly connected to the connecting block and is set on the opening of the through hole side of the connecting block to facilitate the sliding passage of the connecting rod. By rotating the first sliding locking handle, the opening of the through hole side is reduced, thereby achieving locking. Using the first sliding locking handle, the operation is simple and convenient, requiring no tools and improving the convenience of manual operation.

[0024] In this embodiment, the material pulling push plate 105 is located on the left side of the feeding moving seat 107, and the distance between the material pulling push plate 105 and the feeding moving seat 107 is greater than the length of the material.

[0025] In this embodiment, the loading lifting platform 103 is driven to move up and down by the loading lifting drive component 114. Further, the loading lifting platform 103 is mounted on an L-shaped loading lifting frame 115, with the loading lifting platform 102 and the vertical edge of the loading lifting frame 115 sliding vertically together. The loading lifting drive component is mounted on the loading lifting frame. Specifically, the loading lifting drive component 114 includes a loading lifting motor and a sprocket drive component mounted on the loading lifting frame. The chain of the sprocket drive component is connected to the loading lifting platform, and the loading lifting motor is connected to the sprocket of the sprocket drive component. The loading lifting motor drives the loading lifting platform to move up and down through the sprocket drive component.

[0026] In this embodiment, a first sensor 117 for detecting the board material is provided in the feeding channel 202. The first sensor is electrically connected to the feeding lifting motor of the feeding lifting drive through a control unit (such as a PLC). When the first sensor detects that there is no board material in the feeding channel, the control unit receives the signal from the first sensor and controls the feeding lifting drive to work. The feeding lifting drive drives the feeding lifting platform to move upward, thereby lifting several boards upward to the top of the feeding channel.

[0027] In this embodiment, a second sensor 118 for detecting the board material is provided above the loading lifting platform 103. The second sensor 118 and the loading cylinder of the pulling mechanism are electrically connected to the control unit. When the second sensor detects the board material, the control unit receives the signal from the second sensor and controls the loading lifting motor of the loading lifting drive to stop. The control unit controls the loading cylinder of the pulling mechanism to work. The loading cylinder drives the loading moving seat and the pulling push plate to move synchronously from left to right to realize the pushing of the material.

[0028] In this embodiment, both the first sensor and the second sensor can be photoelectric sensors.

[0029] In this embodiment, a horizontally arranged loading slide plate 116 is fixed to the top of the vertical side of the loading lifting frame 115. The right end of the loading slide plate 116 is connected to the top opening of the loading channel 202. The loading slide plate is used to support the plate when it moves from left to right.

[0030] In this embodiment, the feeding assembly 201 includes a feeding seat plate 203 for supporting several vertically stacked plates. The feeding seat plate 203 is provided with a pre-push clamping assembly 204 for pushing the bottommost plate forward and clamping it from the left and right. The pre-push clamping assembly first pushes the bottommost plate forward and clamps it from the left and right to position the plate. The feeding seat plate 203 is driven forward by the feeding moving assembly 205 to move forward, so that the bottommost plate is positioned and then conveyed forward to the clamping mechanism 300 of the CNC copying machine. That is, after the plate is positioned, it is directly conveyed to the clamping mechanism next to the copying tool of the CNC copying machine, without the need for manual feeding and positioning.

[0031] In this embodiment, a feeding channel is formed between the top of the feeding seat plate 203 and the bottom of the front end of the feeding channel 202 to facilitate the forward passage of a single board; a liftable baffle assembly 206 is provided on the front side of the feeding channel 202. The liftable baffle assembly 206 is used to abut against the front end face of the board pushed forward by the pre-push clamping assembly 204. That is, the pre-push clamping assembly pushes the board located at the bottom forward a certain distance, and the front end face of the board contacts the liftable baffle assembly to achieve front-back positioning. Then the pre-push clamping assembly clamps the board from the left and right directions to complete the positioning of the board.

[0032] In this embodiment, the liftable baffle assembly 206 includes a vertical baffle rod 207. The vertical baffle rod 207 is driven downward by a baffle cylinder 208 located above it to move directly in front of the feeding seat plate, so as to facilitate contact with the front end face of the plate being pushed forward by the pre-push clamping assembly. Before feeding, the vertical baffle rod moves downward to directly in front of the plate under the drive of the baffle cylinder; after the plate is positioned (clamped from the left and right directions), the vertical baffle rod returns to its original position upward to avoid obstructing the forward conveying of subsequent plates.

[0033] In this embodiment, the pre-push clamping assembly 204 includes a pre-push moving plate 209 horizontally disposed above the feeding seat plate 203. The pre-push moving plate 209 is driven to move back and forth by the pre-push moving assembly 210 disposed on the feeding seat plate 203. The front end face of the pre-push moving plate 209 is provided with a pair of left and right distributed push blocks 211 for contacting the rear end face of the bottommost plate. The front side of the pair of push blocks 211 is provided with a clamping assembly for clamping the bottommost plate from the left and right directions. Specifically, the clamping assembly includes a pair of longitudinal support plates 212 distributed on the left and right sides of the feeding seat plate 203. The rear end of the pair of longitudinal support plates 212 is connected to the top of the pre-push moving plate 209 by fasteners. Each longitudinal support plate 212 has an L-shaped clamping block 213 disposed on its inner side. Each L-shaped clamping block 213 is driven to move left and right by a clamping cylinder 214 horizontally mounted on the longitudinal support plate 212. During operation: (1) In the initial state, the pre-push moving plate 209 is located behind the feeding channel 202, and a pair of longitudinal support plates 212 are distributed on the left and right sides below the feeding channel 202; when several plates stacked vertically are placed in the feeding channel 202, the feeding seat plate 203 supports several plates, and at this time a pair of push blocks 211 are behind the plates; (2) Plate positioning: the pre-push moving component 210 drives the pre-push moving plate 209 to move forward a certain distance, and the pre-push moving plate 209 pushes the plate at the bottom to move forward until it abuts against the vertical stop bar 207 through a pair of push blocks 211. Then, the clamping cylinders 214 on the pair of longitudinal support plates 212 extend towards each other and clamp. The L-shaped clamping block 213 connected to the cylinder 214 clamps the plate from the left and right sides to achieve plate positioning; (3) Pre-push: The plate is kept in a clamped state, and then the pre-push moving component 210 drives the pre-push moving plate 209 to move the plate forward, so that the plate is in front of the feeding seat plate 203 (in a front-back misalignment state); (4) Feeding: The feeding moving component 205 drives the feeding seat plate 203 to move forward, and the feeding seat plate 203 drives the plate to move forward synchronously until the plate is below the copying tool, so that the plate is on the pressing mechanism 300; (5) The clamping cylinder 214 drives the L-shaped clamping block 213 to retract, release the plate, the feeding seat plate resets backward, and the pre-push moving plate resets backward.

[0034] In this embodiment, the top left and right ends of the pre-push movable plate 209 are provided with a row of mounting holes distributed horizontally. The mounting holes are used to cooperate with fasteners to adjust the installation position of the longitudinal support plate 212 in the horizontal direction, thereby adjusting the spacing between a pair of longitudinal support plates and adapting to clamping plates of different lengths.

[0035] In this embodiment, a pair of longitudinally pushing rods 216 distributed on the left and right are fixed to the rear end face of the pre-pushing moving plate 209. When the plate at the bottom is pushed forward, the pair of longitudinally pushing rods 216 support the remaining plate in the feeding channel 202.

[0036] In this embodiment, longitudinal slots 217 are respectively provided at the left and right ends of the feeding seat plate 203; the pre-push moving assembly 210 includes a pre-push moving seat 218 disposed below the feeding seat plate 203. The pre-push moving seat 218 is driven to move back and forth by a rodless cylinder 219 longitudinally installed at the bottom of the feeding seat plate 203. The top left and right ends of the pre-push moving seat 218 pass through the corresponding longitudinal slots 217 and are connected to the pre-push moving plate 209, so that the pre-push moving plate and the pre-push moving seat form a whole, and the two move back and forth synchronously. Furthermore, pre-push longitudinal guide rods 220 are arranged parallel to each other on the left and right sides of the rodless cylinder, and the pre-push moving seat 218 slides with the pre-push longitudinal guide rods 220.

[0037] In this embodiment, the feeding channel 202 has a rectangular cross-section. Both the length and width of the feeding channel 202 are adjustable to accommodate different sizes of boards, improving usability. Specifically, the feeding channel 202 includes a front side plate 221, a rear side plate 222, a left side plate 223, and a right side plate 224. The front side plate 221 is horizontally arranged, with a fixed guide shaft 225 and a movable guide shaft 226 longitudinally arranged at its left and right ends, respectively. A first slider 227 is fixed to the front end of the movable guide shaft 226. The first slider 227 slides in conjunction with a first transverse groove 228 at the right end of the front side plate 221. A second slider 229 is slidably connected to the movable guide shaft 226 behind the first slider 227. The second slider 229 slides in conjunction with a second transverse groove 230 at the top right end of the horizontally arranged rear side plate 222. The left end of the rear side plate 222 slides in conjunction with the fixed guide shaft 225 via a third slider 231. The left side plate 223 and the right side plate 224 are both... The two plates are arranged in a front-to-back configuration. The left side plate 223 at the front end is fixedly connected to the fixed guide shaft 225. The left side plate 223 at the rear end is fixedly connected to the rear side plate 222 and can move back and forth with the rear side plate. That is, the distance between the two left side plates is adjustable, and the distance between the front and rear side plates is adjustable. The right side plate 224 at the front end is fixedly mounted on the movable guide shaft 226 through the guide shaft support 232. The right side plate 224 at the rear end is fixedly connected to the second slider 229. That is, when the movable guide shaft 226 moves left and right, the two right side plates 224 move synchronously with the movable guide shaft 226, so that the distance between the left side plate 223 and the right side plate 224 is adjustable. The right side plate 224 at the rear end can move back and forth with the rear side plate 222, so that the distance between the two right side plates 224 is adjustable.

[0038] In this embodiment, the first slider 227, the second slider 229, and the third slider 231 are all equipped with a second sliding locking handle for locking after adjustment. It should be noted that the second sliding locking handle on the slider is an existing mature product (e.g., the existing SCS box-type slider). It is connected to the slider, and by rotating the second sliding locking handle, the slider can be locked in place and cannot be moved. Using the second sliding locking handle makes operation simple and convenient, requiring no tools and improving the convenience of manual operation.

[0039] In this embodiment, both the left side plate 223 and the rear side plate 222 are L-shaped. The vertical edge of the left side plate 223, the vertical edge of the rear side plate 222, the front side plate 221, and the right side plate 224 form a feeding channel 202. The second transverse chute 230 is disposed on the horizontal edge of the rear side plate 222. A transverse support rod 234 is disposed parallel to the rear of the rear side plate 222. The rear end of the fixed guide shaft 225 is fixedly connected to the transverse support rod 234, and the rear end of the movable guide shaft 226 is slidably connected to the transverse support rod 234. The left and right ends of the transverse support rod are supported on the machine platform. A downwardly protruding limiting protrusion is provided in the middle of the bottom surface of the front side plate. A feeding channel is formed between the bottom of the limiting protrusion and the top of the feeding seat plate to facilitate the passage of a single piece of material.

[0040] In this embodiment, the feeding base plate 203 is slidably engaged with a pair of feeding guide shafts 235 longitudinally disposed below it; the feeding moving assembly includes a feeding rack 236, a feeding gear 237, and a feeding motor 238. The feeding rack 236 is longitudinally installed at the right end of the feeding base plate 203, and the feeding motor 238 is installed on the machine base 101. The output shaft of the feeding motor 238 is connected to the feeding gear 237, and the feeding gear 237 meshes with the feeding rack 236. When the feeding gear rotates, it drives the feeding rack and the feeding base plate to move in the forward and backward directions.

[0041] In this embodiment, the clamping mechanism 300 includes a horizontally arranged rotating pallet 301 for supporting the sheet metal. The rotating pallet 301 is rotatably mounted on the machine base 101. The rotating pallet 301 is used to receive the sheet metal pushed from back to front by the feeding assembly 201. The rotating pallet 301 is driven to rotate by a rotating power component 302 (such as a rotary motor) located below it. An upper pressure plate 303 is arranged parallel to the top of the rotating pallet 301. The upper pressure plate 303 is driven to move up and down by a clamping drive component 304 (such as a vertically arranged clamping cylinder). The upper pressure plate 303 is rotatably connected to the moving end of the clamping drive component 304. During operation, the feeding assembly conveys the sheet metal from back to front onto the rotating pallet. Then, the upper pressure plate moves downward to press the sheet metal. The upper pressure plate and the rotating pallet cooperate to clamp the sheet metal from the upper and lower sides. The rotating pallet drives the sheet metal and the upper pressure plate to rotate so that the subsequent contouring tool can process the sheet metal.

[0042] In this embodiment, the contouring tool 500 is driven to rotate by a power motor 501 through a transmission component 502 (with a transmission component). The power motor, the transmission component, and the contouring tool are driven to move horizontally and vertically by a two-dimensional moving module 503.

[0043] In this embodiment, the discharge mechanism 400 includes a horizontally arranged conveyor belt 401, which is used to transport the processed sheet material from right to left. A discharge lifting platform 402 is provided on the left side of the conveyor belt 401 to connect and vertically stack the processed sheet material. Furthermore, a longitudinally arranged discharge baffle 403 is provided above the right end of the conveyor belt.

[0044] It should be noted that the structure of the unloading lifting platform is the same as that of the loading lifting platform, only the working process is reversed. The loading lifting platform lifts from bottom to top, while the unloading lifting platform receives the output plates and descends from top to bottom. It descends after receiving each plate. The structure and lifting principle of the unloading lifting platform will not be repeated here.

[0045] In this embodiment, a protective cover 600 is provided on the machine base 101. The protective cover covers the contour cutting tool, the clamping mechanism, etc., and plays a protective role.

[0046] Specific implementation process: (1) Loading: The manual first stacks multiple boards vertically and places them on the loading lifting platform 103. The loading lifting platform 103 lifts several boards upward to the top of the loading channel 202 each time. Then the pulling mechanism 104 pushes several boards from left to right into the loading channel 202. (2) Positioning: The pre-push moving component 210 drives the pre-push moving plate 209 to move forward a certain distance. The pre-push moving plate 209 pushes the plate located at the bottom forward through a pair of push blocks 211 until it abuts against the vertical stop bar 207. Then, the clamping cylinders 214 on a pair of longitudinal support plates 212 extend towards each other. The L-shaped clamping block 213 connected to the clamping cylinder 214 clamps the plate from the left and right sides to achieve positioning of the plate. (3) Pre-push: The plate is kept in a clamped state, and then the pre-push moving component 210 drives the pre-push moving plate 209 to move the plate forward, so that the plate is located in front of the feeding seat plate 203 (in a front-back misaligned state). (4) Feeding: The feeding moving component 205 drives the feeding seat plate 203 to move forward, and the feeding seat plate 203 drives the plate to move forward synchronously until the plate is located on the rotating pallet. (5) Pressing: The upper pressure plate 303 moves downward to press the plate. The upper pressure plate 303 and the rotating support plate 301 cooperate to clamp the plate from the upper and lower sides. The plate rotates under the drive of the rotating support plate 301. (6) Machining: A 500-grip profile cutting tool is used to machine the sheet metal; (7) Discharge: After processing, repeat step (4). The feeding seat plate 203 drives the new plate to be processed to move from back to front. The plate to be processed pushes the processed plate on the rotating pallet forward to the conveyor belt. The conveyor belt transports the processed plate from right to left to the unloading lifting platform to realize discharge.

[0047] The advantages of this utility model are: (1) The structure layout is reasonable, which reduces unnecessary connection losses and significantly improves the overall production speed and quality; (2) The size of the material pulling mechanism and the feeding channel can be flexibly adjusted. When changing the processing object, it is not necessary to frequently change the tooling, which reduces the technical requirements of operation and improves the convenience of operation; (3) The whole process does not require manual placement, positioning and unloading, which effectively liberates manual operation, reduces the intensity of manual labor, reduces operation time, and thus improves the overall production efficiency.

[0048] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then, unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).
