Description

Technical Field

[0001] The invention relates to the technical field of cast iron profile cutting, and in particular to a fully automatic cutting device for continuous production of cast iron profiles. Background Art

[0002] Cast iron profiles, as an iron-carbon alloy with a high carbon content, have been widely used in many industries such as machinery manufacturing, construction, and pipelines due to their excellent hardness characteristics. For example, they are used to manufacture band saw machine bodies, valves, and pipelines. After the production process is completed, profiles usually need to be cut according to specific length requirements to meet subsequent use needs. In the existing processing process, profile cutting often adopts a continuous equidistant cutting method.

[0003] After the profile is produced, it needs to be cut into a certain length before use. During the processing, continuous equidistant cutting is usually performed.

[0004] Referring to the Chinese patent document with the authorization publication number CN117505966B and the announcement date of February 6, 2024, and the name of the patent document is a photovoltaic aluminum material processing automatic cutting device, wherein the cutting device includes a base with a cavity inside, a transport mechanism for transporting aluminum profiles is provided on the base, a cutting mechanism for multi-directional fixation of the cut aluminum profiles is provided on the base, and a correction mechanism for correcting the expansion holes at both ends of the cut aluminum profiles is also provided on the base. Through the coordinated use of the transport mechanism, the cutting mechanism and the correction mechanism, the aluminum profile is transported to the cutting position by limiting the position, so as to fix the cutting position of the aluminum profile.

[0005] With regard to the above-mentioned related technologies, as the cutting process continues, the total length of the profile to be cut gradually shortens. When the size of the finished profile to be cut is narrow, the existing transportation mechanism has difficulty in pushing the profile tailings. At the same time, the fixing structure on the cutting mechanism is also difficult to effectively fix the profile tailings. The remaining profile tailings usually need to be moved manually. However, cast iron profiles are heavy and are subject to the size restrictions of the finished profiles and the cutting mechanism. There is a high safety risk during manual operation. Especially for cylindrical profiles, the fixing effect is not good. During the cutting process, the cylindrical profile tailings are more likely to tilt and other problems. It may also cause material waste and reduce the cutting effect. In addition, if the profile is not fixed stably during the cutting process, vibration or movement occurs, it will cause uneven force on the saw blade, which is easy to cause the saw to jam. Summary of the invention

[0006] In view of this, the present invention provides a fully automatic cutting device for continuous production of cast iron profiles, aiming to solve the technical problems in the prior art of difficult feeding and poor fixing effect when the remaining length of the profile is short.

[0007] In order to solve the above technical problems, the present invention provides a fully automatic cutting device for continuous production of cast iron profiles, which adopts the following technical solutions: a fully automatic cutting device for continuous production of cast iron profiles, comprising a band sawing machine body and a ring saw and a cutting table, a support table, and a transport member for conveying profiles, which are arranged in sequence from left to right on the top surface of the band sawing machine body and vertical positions corresponding to the ring saw and the cutting table, and a clamping assembly for fixing both sides of the profiles;

[0008] A connecting plate rotatably connected to the side wall of the support platform and a rotating member for driving the connecting plate to rotate, a telescopic cylinder is fixedly connected to the top surface of the connecting plate, and a push block is connected to the output end of the telescopic cylinder;

[0009] The control cylinder, baffle, cam 1 and cam 2 are arranged in sequence from left to right. The control cylinder is connected to the left end of the cutting table, the baffle is connected to the output end of the control cylinder, and the cutting table is connected to two support seats which are arranged on both sides of the circular saw in sequence. The support seats are vertically slidably connected to support plates. Cam 1 and cam 2 are rotatably connected to the bottom of the two support plates in sequence. Both support plates are provided with driving members, and the two groups of driving members are symmetrically arranged.

[0010] The driving member includes a hydraulic pipeline arranged in the support plate, the left end of the hydraulic pipeline is connected to the interior of the cylinder body of the control cylinder, and a height adjustment cylinder and a downward pressure cylinder, both of which are connected to the interior of the cylinder body with the hydraulic pipeline, are arranged above and below the support plate in sequence. The output end of the height adjustment cylinder extends upward and is connected to the support seat, and the output end of the downward pressure cylinder extends downward and is connected to a rack. A fixed sleeve at one end of the cam is provided with a gear meshing with the rack, and a torsion spring is provided between the cam and the support plate to make the cam have a counterclockwise rotation tendency, and a limit plate that can abut against the right side of the cam is connected to the right side of the bottom surface of the support plate.

[0011] By adopting the above technical solution, a connecting plate and a push block are set. When the remaining length of the profile is short, the connecting plate rotates, and the telescopic cylinder pushes the push block so that the push block abuts against the right end of the profile. The push block can push the profile for loading, thereby reducing the safety risks in the processing process and ensuring the personal safety of the workers. A baffle is added, and the baffle abuts against the left end of the profile. Under the joint action of the baffle and the push block, the fixing effect of the profile is improved, and the tilting of the profile during the cutting process is avoided as much as possible.

[0012] After the baffle plate abuts against the left end of the profile, the hydraulic oil in the control cylinder flows to the hydraulic pipeline, and the output end of the downward pressure cylinder is subject to the resistance transmitted by the torsion spring. The output end of the downward pressure cylinder is stationary, and the output end of the height adjustment cylinder is upward. Taking cam 1 as an example, the support plate, cam 1 and downward pressure cylinder move downward synchronously. When the bottom surface of cam 1 connects with the top of the profile, the profile prevents the support plate from moving downward, and the output end of the height adjustment cylinder is stationary. During this process, the hydraulic oil pressure in the hydraulic pipeline continues to increase, so that the output end of the downward pressure cylinder transmits force to cam 1 through the rack and gear, so that cam 1 has a clockwise rotation trend, and cam 1 transmits the force to the profile.

[0013] Cam 1 and cam 2 respectively limit the two parts of the profile being cut, which can further reduce the tilting of the profile during cutting, improve the stability of the cutting process, and help improve the poor cutting effect and saw jamming caused by poor fixing effect; Cam 1 and cam 2 have a tendency to move away from each other. Cam 1 and cam 2 apply force to the profile, so that the two parts of the cut profile produce a moment of force that diverges from each other, which can further reduce the risk of saw jamming. The cam structure can effectively transmit a large force to the profile to ensure the stability of the structure.

[0014] Optionally, the band saw body is provided with a moving part for driving the support platform to reciprocate along the axial direction of the profile.

[0015] By adopting the above technical solution, the disadvantage of the limited moving range of the output end of the telescopic cylinder can be compensated and the application scope of the device can be expanded.

[0016] Optionally, the baffle is an electromagnetic chuck.

[0017] By adopting the above technical solution, the baffle can absorb the cut profile, and the control cylinder drives the baffle to move to the left, so that the cut profile is away from the circular saw, which is convenient for unloading. This can improve the stability and convenience of the unloading process and reduce possible dangers in the cutting process.

[0018] Optionally, the baffle is hinged to the output end of the control cylinder.

[0019] By adopting the above technical solution, the baffle drives the cut profile away from the circular saw. Under the action of the gravity of the profile, the baffle rotates along the hinge axis, the baffle is powered off, and it is easy to separate from the profile, allowing the profile to fall naturally.

[0020] Optionally, a guide plate is connected to the bottom of the left end of the cutting table and is tilted from top to bottom and leftward.

[0021] By adopting the above technical solution, the cut profile is guided so that after the baffle is powered off and separated from the profile, the profile falls downward onto the guide plate and slides down, which facilitates the collection of the cut profile, reduces the risk of the unloading process, and improves the safety of the device.

[0022] Optionally, the baffle is controlled to be powered on and off in sequence by two photoelectric sensors.

[0023] By adopting the above technical solution, the photoelectric sensor is used to monitor the baffle position and can control the power on and off of the baffle. When the baffle is powered on, it absorbs the cut profile and drives the profile to move to the unloading point; when the baffle is powered off, the profile moves under its own gravity to complete the unloading.

[0024] Optionally, a through slot is formed on the side wall of the support platform, the connecting plate is rotatably disposed in the through slot, a rotating motor is disposed inside the support platform, and an output end of the rotating motor extends upward into the through slot and is fixedly connected to an end of the connecting plate.

[0025] By adopting the above technical solution, the support platform supports the profile, and the through groove is provided to facilitate the rotation of the connecting plate, and can avoid conflicts between structures, thereby facilitating a reasonable layout.

[0026] Optionally, a limiting block cooperating with the pushing block is fixedly connected to one end of the support platform.

[0027] By adopting the above technical solution, the push block and the limit block are matched to limit the profile on the support platform, thereby reducing the deviation of the profile during the movement.

[0028] In summary, the present invention includes the following beneficial technical effects:

[0029] 1. Set up a connecting plate and a push block. When the remaining length of the profile is short, the connecting plate rotates, and the telescopic cylinder pushes the push block so that the push block abuts against the right end of the profile. The push block can push the profile for loading, reducing the safety risks in the processing process and ensuring the personal safety of the staff; add a baffle, which abuts against the left end of the profile. Under the joint action of the baffle and the push block, the fixing effect of the profile is improved, and the tilting of the profile during the cutting process is avoided as much as possible;

[0030] Cam 1 and cam 2 respectively limit the two parts of the profile being cut, which can further reduce the tilting of the profile during cutting, improve the stability of the cutting process, and help improve the poor cutting effect and saw jamming caused by poor fixing effect; Cam 1 and cam 2 have a tendency to move away from each other. Cam 1 and cam 2 apply force to the profile, so that the two parts of the cut profile produce a moment of force that diverges from each other, which can further reduce the risk of saw jamming. The cam structure can effectively transmit a large force to the profile to ensure the stability of the structure.

[0031] 2. The moving parts can make up for the shortcoming of the limited moving range of the output end of the telescopic cylinder and expand the application scope of the device.

[0032] 3. The setting of the baffle and the guide plate enables the baffle to absorb the cut profile. The control cylinder drives the baffle to move to the left, so that the cut profile is away from the circular saw, and the profile can slide along the guide plate and complete the unloading, which is convenient for unloading. It can improve the stability and convenience of the unloading process and reduce the possible dangers in the cutting process. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0042] The following is combined with Figure 1 -Attached Figure 7 The present invention is described in further detail.

[0043] The embodiment of the present invention discloses a fully automatic cutting device for continuous production of cast iron profiles. Figures 1 to 7A fully automatic cutting device for continuous production of cast iron profiles, including a processing mechanism, a feeding mechanism and an auxiliary mechanism. The processing mechanism is used to transport the profiles and perform preliminary fixation and cutting of the profiles. When the profiles become shorter, it is difficult for the processing mechanism to feed and clamp the profiles. The feeding mechanism moves the profiles to the cutting position for cutting. The auxiliary mechanism fixes the profiles again before cutting. The multi-angle fixation ensures the smooth progress of the cutting process. The auxiliary mechanism can make the two parts of the profile to be cut have a moment of force that deviates from each other, so as to avoid the situation of saw jamming during the cutting process as much as possible. After the profile cutting is completed, the auxiliary mechanism discharges the cut profiles.

[0044] Reference Figure 1 , Figure 2 and Figure 4 The processing mechanism includes a band saw body 1, a circular saw 2, a cutting table 3, a supporting table 4, a transport member 5 and a clamping assembly 6.

[0045] Reference Figure 1 The long side of the band saw machine body 1 extends left and right, the wide side of the band saw machine body 1 extends front and back, and the height of the band saw machine body 1 extends up and down. Figure 1 and Figure 2 The cutting table 3, the supporting table 4 and the transporting member 5 are arranged on the top surface of the band saw machine body 1 from left to right. The circular saw 2 corresponds to the cutting table 3 in the vertical direction. The bottom of the circular saw 2 is connected to the band saw machine body 1. The cutting table 3 is used to support the end of the profile. The circular saw 2 moves downward and cuts the profile to the required size. The supporting table 4 is used to support the profile part between the transporting member 5 and the cutting table 3, so that the profile can move smoothly to the bottom of the circular saw 2. Figure 4 The clamping assembly 6 is arranged on the cutting table 3, and the clamping assembly 6 fixes both sides of the profile, and the clamping assembly 6 can fix the profiles located on both sides of the circular saw 2, so as to limit the position of the profile, so that the cutting process can proceed smoothly.

[0046] Reference Figure 1 Specifically, the transport member 5 includes a plurality of transport rollers arranged in parallel and capable of rotating around their own axes. The roller axes of the transport rollers extend forward and backward, and the axial direction of the profile extends left and right. The profile is placed on the transport rollers, and the transport rollers rotate to drive the profile to move leftward. Furthermore, in other embodiments, the transport member 5 can also be conveyed by a belt or the like to move the profile forward to the bottom of the ring saw 2.

[0047] Reference Figure 4Specifically, the clamping assembly 6 is provided with two groups and the two groups of clamping assemblies 6 are arranged in parallel in the left-right direction, and the two groups of clamping assemblies 6 are respectively placed on both sides of the circular saw 2. The clamping assembly 6 includes a fixed plate 61, a movable plate 62 and a clamping cylinder 63. The fixed plate 61 is fixedly connected to the front side of the cutting table 3, the movable plate 62 is slidably connected to the rear side of the cutting table 3 along the front-back direction, the clamping cylinder 63 is fixedly connected to the rear side of the cutting table 3, and the movable plate 62 is fixedly connected to the output end of the clamping cylinder 63. The circumferential side wall of the profile first abuts against the rear side of the fixed plate 61, and the clamping cylinder 63 is started, and the movable plate 62 moves to abut against the circumferential side wall of the profile. The movable plate 62 cooperates with the fixed plate 61 to limit the position of the profile, which is convenient for the stable cutting process. Furthermore, in other embodiments, the clamping assembly 6 can also use an arc plate or the like to limit the profiles on both sides of the circular saw 2, so as to achieve the purpose of avoiding the movement of the profiles during the cutting process as much as possible.

[0048] When in use, the profile is placed horizontally on the transport rollers for transportation, and the profile extends axially to the left and right. When the profile is transported to the cutting table 3, it is pushed by two clamping cylinders 63, so that the two movable plates 62 cooperate with the two fixed plates 61 to fix the profile on both sides of the circular saw 2, and the circular saw 2 is started to cut the profile.

[0049] Reference Figure 2 and Figure 3 The feeding mechanism includes a connecting plate 7, a rotating member 8, a telescopic cylinder 9, a push block 10, a moving member 11 and a limit block 12. The push block 10 can abut against the right end of the profile to push the feeding of the shorter profile.

[0050] Reference Figure 2 and Figure 3 The side wall of the support platform 4 is provided with a through slot extending forward and backward, and one end of the connecting plate 7 is rotatably connected to the inner wall of the through slot. Specifically, the rotating member 8 includes a rotating motor, which is arranged in the support platform 4. The output end of the rotating motor extends upward and extends into the through slot. The output end of the rotating motor is fixedly connected to the end of the connecting plate 7. When the rotating motor is started, the connecting plate 7 is driven to rotate. The telescopic cylinder 9 is fixedly connected to the end of the connecting plate 7 away from the support platform 4. The output end of the telescopic cylinder 9 extends horizontally, and the push block 10 is fixedly connected to the output end of the telescopic cylinder 9. After hiding part of the support block, the rotating motor located inside the support block can be exposed.

[0051] Reference Figure 3 The limit block 12 is connected to the front end of the connecting plate 7, and the limit block 12 can cooperate with the push block 10 to limit the position of the profile.

[0052] Reference Figure 2Specifically, the moving member 11 includes a moving cylinder, which is fixedly connected to the top surface of the band saw machine body 1, and the output end of the moving cylinder extends to the left. The moving cylinder is placed under a plurality of transport rollers. Two parallel shafts are provided between the left side of the transport member 5 and the right side of the cutting table 3. The support table 4 is slidably connected to the two shafts, and the output end of the moving cylinder is fixedly connected to the right side of the support table 4. It can make up for the limited moving range of the output end of the telescopic cylinder 9, expand the range of movement of the push block 10 in the left and right directions, and thus expand the scope of application of the device. Furthermore, in other embodiments, the support table 4 can also be fixedly connected to the top surface of the band saw machine body 1. In this embodiment, the moving cylinder plays a role in further improving the flexibility and scope of application of the device.

[0053] When the length of the profile is long, the profile can be moved to the bottom of the circular saw 2 by the transport member 5. At this time, the telescopic cylinder 9 and the push block 10 are placed at the rear side of the profile. The push block 10 cooperates with the limit block 12, which are respectively located at the front and rear sides of the profile. The profile is limited, which can avoid conflicts between structures as much as possible, and can improve the stability of the profile transportation process and reduce the deviation of the profile during transportation as much as possible. When the remaining length of the profile is short, the rotating motor is started, the connecting plate 7 rotates, the push block 10 abuts against the right end of the profile, the telescopic cylinder 9 and the moving cylinder are started, and the push block 10 pushes the profile to move to the left, so that the shorter profile can also move smoothly to the bottom of the circular saw 2.

[0054] Reference Figure 4 and Figure 6 The auxiliary mechanism includes a control cylinder 13, a baffle 14, a guide plate 15, a cam 1 16, a cam 2 17, two support seats 18, two support plates 19 and two sets of driving parts 20.

[0055] Reference Figure 2 , the control cylinder 13 is fixedly connected to the left side of the cutting table 3, and the output end of the control cylinder 13 extends to the right. Figure 4 , the control cylinder 13, the baffle 14, the cam 1 16 and the cam 2 17 are arranged in sequence from left to right (wherein, in order to clearly show the structure in the figure, Figure 4 Schematic diagram of other viewing angles after the model diagram is reversed, the "left" and "right" described in the text refer to the previous text and the marks in the figure), the baffle 14 can abut against the left end of the profile, the baffle 14 cooperates with the push block 10 to limit the position of the profile, the cam 16 and the cam 2 17 are respectively arranged on both sides of the circular saw 2, the cam 1 16 and the cam 2 17 move vertically and can abut against the top of the profile, and after abutting against the top of the profile, the cam 1 16 and the cam 2 17 have a tendency to move away from each other, so that the two parts of the profile being cut have a torque moving away from each other, thereby achieving the purpose of avoiding saw jamming as much as possible.

[0056] The baffle 14 is hinged to the output end of the control cylinder 13. The baffle 14 is an electromagnetic suction cup. The power on or off of the baffle 14 is controlled by two photoelectric sensors connected to the cutting table 3. The guide plate 15 is connected to the left side of the cutting table 3. The guide plate 15 is tilted to the left from top to bottom. The guide plate 15 is located below the control cylinder 13. The baffle 14 drives the cut profile away from the circular saw 2. Under the gravity of the profile, the baffle 14 rotates along the hinge axis. The baffle 14 is powered off, which is convenient for separation from the profile and allows the profile to fall naturally. The guide plate 15 is used to guide the cut profile, so that after the baffle 14 is powered off and separated from the profile, the profile falls downward onto the guide plate 15 and slides down, which is convenient for collecting the cut profile, reducing the risk of the unloading process and improving the safety of the device.

[0057] Reference Figure 4 The two support seats 18 are sequentially connected to the top surfaces of the two fixed plates 61, and the two support plates 19 are sequentially vertically slidably connected to the two support seats 18. The cam 1 16 and the cam 2 17 are sequentially rotatably connected to the bottoms of the two support plates 19. The two sets of driving members 20 correspond to the cam 1 16 and the cam 2 17 one by one, and the two sets of driving members 20 are symmetrically arranged.

[0058] Reference Figure 6 and Figure 7 The driving component 20 includes a hydraulic pipeline 201, two height adjustment cylinders 202, a pressing cylinder 203, a rack 204, a gear 205, a torsion spring and a limit plate 206.

[0059] Reference Figure 7 The hydraulic pipeline 201 extends in the left-right direction. The hydraulic pipeline 201 is placed inside the support plate 19. The left end of the hydraulic pipeline 201 is connected to the inside of the cylinder body of the control cylinder 13 through a pipeline, so that the hydraulic oil in the control cylinder 13 can flow to the hydraulic pipeline 201 through the pipeline. The pipeline for connecting the control cylinder 13 and the hydraulic pipeline 201 is not shown in the figure. Figure 7 The shaded portion of the support plate 19 on the left side is a schematic diagram of a portion of the support plate 19 that has been cut to facilitate the display of the hydraulic pipeline 201 .

[0060] The two height adjustment cylinders 202 are arranged in parallel in the left-right direction, the cylinder body of the height adjustment cylinder 202 is connected to the top surface of the support plate 19, the cylinder body of the height adjustment cylinder 202 is connected to the inside of the hydraulic pipeline 201, and the output end of the height adjustment cylinder 202 extends upward and is connected to the support seat 18. The cylinder body of the pressing cylinder 203 is connected to the bottom surface of the support plate 19, the cylinder body of the pressing cylinder 203 is connected to the inside of the hydraulic pipeline 201, the output end of the pressing cylinder 203 extends downward, and the rack 204 is fixedly connected to the left side of the output end of the pressing cylinder 203.

[0061] The gear 205 is fixedly sleeved on the front end of the cam 16, and the gear 205 is meshed with the rack 204. The gear 205 is located on the left side of the rack 204, and the gear 205 is meshed with the rack 204. When the rack 204 has a downward movement tendency, the gear 205 has a clockwise rotation tendency.

[0062] The torsion spring is arranged between the support plate 19 and the cam 16, and transmits force to the cam 16, so that the cam 16 has a movement tendency of rotating counterclockwise.

[0063] The limit plate 206 is connected to the bottom surface of the support plate 19, and is located on the right side of the cam 16. The bottom surface of the limit plate 206 is tilted from top to bottom and rightward. Under the action of the torsion spring, the cam 16 abuts against the bottom surface of the limit plate 206. The limit plate 206 can ensure the initial position of the cam 16 and enhance the stability of the device.

[0064] After the baffle 14 abuts against the left end of the profile, the hydraulic oil in the control cylinder 13 flows to the hydraulic pipeline 201, and the output end of the pressing cylinder 203 is subjected to the resistance transmitted by the torsion spring. The output end of the pressing cylinder 203 is stationary, and the output end of the height adjustment cylinder 202 moves upward. Taking cam 16 as an example, the support plate 19, cam 16 and pressing cylinder 203 move downward synchronously. When the bottom surface of cam 16 connects with the top of the profile, the profile prevents the support plate 19 from moving downward, and the output end of the height adjustment cylinder 202 is stationary. During this process, the hydraulic oil pressure in the hydraulic pipeline 201 continues to increase, so that the output end of the pressing cylinder 203 transmits force to cam 16 through the rack 204 and the gear 205, so that cam 16 has a clockwise rotation trend, and cam 16 transmits force to the profile.

[0065] Correspondingly, the cam 17 has a counterclockwise rotation tendency. The cam 1 16 and the cam 2 17 respectively limit the two parts of the profile being cut, which can further reduce the tilting during the profile cutting process, improve the stability of the cutting process, and help improve the poor cutting effect and saw jamming caused by poor fixing effect; under the action of the driving member 20, the cam 1 16 and the cam 2 17 have a movement tendency to deviate from each other. The cam 1 16 and the cam 2 17 apply force to the profile, so that the two parts of the profile being cut produce a torque that deviates from each other, which can further reduce the risk of saw jamming. The cam structure can effectively transmit a large force to the profile to ensure the stability of the structure.

[0066] The implementation principle of a fully automatic cutting device for continuous production of cast iron profiles in an embodiment of the present invention is as follows:

[0067] When the length of the profile is long, the profile can be moved to the bottom of the circular saw 2 by the transport member 5. The profile is placed horizontally on the transport member 5 for transportation, and the telescopic cylinder 9 and the push block 10 are placed at the rear side of the profile, and the push block 10 cooperates with the limit block 12, which are respectively located at the front and rear sides of the profile to limit the profile.

[0068] When the remaining length of the profile is shorter, start the rotating motor, the connecting plate 7 rotates, the push block 10 abuts against the right end of the profile, start the telescopic cylinder 9 and the moving cylinder, the push block 10 pushes the profile to move to the left, so that the shorter profile can also move smoothly under the circular saw 2.

[0069] Before the profile is cut, the two clamping cylinders 63 push the two movable plates 62 to match the two fixed plates 61 to fix the profiles on both sides of the ring saw 2.

[0070] Then the control cylinder 13 drives the baffle 14, and the baffle 14 abuts against the left end of the profile. After the baffle 14 abuts against the left end of the profile, the hydraulic oil in the control cylinder 13 flows to the hydraulic pipeline 201, and the output end of the pressing cylinder 203 is subjected to the resistance transmitted by the torsion spring. The output end of the pressing cylinder 203 is stationary, and the output end of the height adjustment cylinder 202 moves upward. Taking the cam 16 as an example, the support plate 19, the cam 16 and the pressing cylinder 203 move downward synchronously. When the bottom surface of the cam 16 is connected with the top of the profile, the profile prevents the support plate 19 from moving downward, and the output end of the height adjustment cylinder 202 is stationary. In this process, the hydraulic oil pressure in the hydraulic pipeline 201 continues to increase, so that the output end of the pressing cylinder 203 transmits force to the cam 16 through the rack 204 and the gear 205, so that the cam 16 has a clockwise rotation trend, and the cam 16 transmits the force to the profile. Correspondingly, the cam 2 17 has a counterclockwise rotation tendency, so that the two parts of the profile being cut generate a moment of force that deviates from each other.

[0071] The circular saw 2 is started to move downward to cut the profile. After the cutting is completed, the photoelectric sensor controls the baffle 14 to energize the baffle 14, and the baffle 14 absorbs the cut profile. The control cylinder 13 drives the baffle 14 and the profile to move left. When it moves to the top of the guide plate 15, under the action of the gravity of the profile, the baffle 14 rotates to an inclined state, and the photoelectric sensor controls the baffle 14 to cut off the power. The profile falls naturally and moves along the guide plate 15 to complete the unloading. When the control cylinder 13 drives the baffle 14 to move left, the hydraulic oil in the hydraulic pipeline 201 is pumped away by the hydraulic cylinder, the height adjustment cylinder 202 is reset, and the cam 1 16 and the cam 2 17 move up and complete the reset.
