Description

Technical Field

[0001] The invention belongs to the technical field of rotary disc cutter shears, and in particular relates to a cutting device for processing radiator aluminum profiles. Background Art

[0002] Radiator aluminum profiles refer to aluminum alloy profiles used to make radiators. Radiators are components used to dissipate heat generated by electronic equipment, motors, transformers and other equipment, and aluminum profiles are widely used in the manufacture of radiators due to their good thermal conductivity, light weight, corrosion resistance and easy processing and forming.

[0003] When manufacturing a radiator, the entire radiator aluminum profile will be cut into pieces to obtain independent radiator products of required length. When a rotary disc knife shearing machine is used as a cutting device for the radiator aluminum profile, one end of the fin of the radiator aluminum profile is fixed to the entire radiator profile to form a fixed end, and the other end of the fin is extended away from the entire radiator profile to form a free end. Because the rotating blade used by the rotary disc knife shearing machine cuts through mechanical friction, continuous downward pressure needs to be applied to the radiator profile during cutting. This pressure acts on the free end of the fin, which will cause disordered vibration and compressive deformation of the fin. When cutting with rapid downward pressure, stress fatigue or even fracture will occur at the root of the fin. In view of this, a cutting device for processing radiator aluminum profiles is provided. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a cutting device for processing radiator aluminum profiles.

[0005] The technical solution adopted to solve the above technical problems is:

[0006] A cutting device for processing radiator aluminum profiles, comprising a shearing machine and a rotating disc cutter group, and also comprising:

[0007] An overhead seat connecting the shearing machine and the rotating disc cutter group, the overhead seat drives the rotating disc cutter group to move vertically in the height direction, and a slag discharge port is opened at the corresponding rotating blade of the shearing machine;

[0008] The radiator profile is placed between the shearing machine and the rotating disc cutter group, and the rotating blade of the rotating disc cutter group cuts the radiator profile into a main body to be cut and a finished aluminum profile. The main body to be cut and the finished aluminum profile have fins arranged in parallel, and a horizontal gap with a single-side opening is formed between the fins;

[0009] Positioning frame 1 and positioning frame 2 are used to clamp the main body to be cut and the finished aluminum profile. The positioning frame 1 and positioning frame 2 are respectively fixed on the top surface of the shearing machine close to the main body to be cut and the finished aluminum profile and one end of the rotating blade. The positioning frame 1 and positioning frame 2 are located in the horizontal gap and are provided with a main board and a support frame. When the main board is translated and pressed against the vertical side walls of the main body to be cut and the finished aluminum profile, the support frame is pressed and contacted with the horizontal side wall of the free end of the fin.

[0010] Furthermore, the positioning frame 1 and the positioning frame 2 are completely identical in structure except for the difference in installation position, and the positioning frame 1 and the positioning frame 2 are arranged symmetrically front to back in groups of two, and an installation spacing is reserved between the positioning frame 1 and the positioning frame 2 in the same group for the radiator profile to pass through, and a translation frame is installed between the positioning frame 1 and the positioning frame 2 in the same group and the fixed frame of the shearing machine, and a driving component is fixedly installed between the translation frame and the fixed frame.

[0011] Through the above technical solution, positioning frame one and positioning frame two are grouped in pairs, and can clamp the radiator profile front and back to fix it for stable cutting. After cutting, they are driven away from each other, and the radiator profile can be pushed for the next cutting, with flexible material discharge, clamping and positioning functions.

[0012] Furthermore, a notch is provided at the lower edge of the radiator profile, a clamping column is provided at the position of the translation frame corresponding to the notch, a pressing block is provided at the position of the translation frame above the notch, and a rounded chamfer is provided at the edge of the pressing block.

[0013] Through the above technical solution, in order to improve the accuracy of cutting length during cutting, equidistant notches are opened on the radiator profile, and fixed-length loading can be conveniently carried out by using clamping columns and notches. The clamping firmness can be improved by clamping the clamping columns and notches to ensure that the radiator profile will not move horizontally during cutting.

[0014] Furthermore, the support frame is provided with multiple parts and is located in the horizontal gap formed between the fins. The support frame includes a parallel plate and an action member. The action member can be deformed when the parallel plate is pressed against the vertical side walls of the main body to be cut and the finished aluminum profile. After the deformation, the action member is pressed into contact with the horizontal side wall of the free end of the fin.

[0015] Through the above technical solution, the parallel plates of the support frame can assist the main board to press against the main body to be cut and the vertical side walls of the finished aluminum profile. Through multi-point pressure clamping in the horizontal direction, the level of the radiator profile clamping is ensured to avoid twisting and tilting in the front and rear directions. The acting parts do not contact the fins before clamping to avoid scratching the outer surface of the fins during the clamping process. After clamping, the acting parts clamp the fins from the top and bottom directions to avoid bending and deformation of the fins.

[0016] Furthermore, the active member includes a contact frame 1 and a contact frame 2, wherein an end block is installed at one end of the contact frame 1 and the contact frame 2 connected to each other, and the contact frame 1 and the contact frame 2 are away from each other at one end facing away from the end block, and an oblique opening is opened on the parallel plate for the contact frame 1 and the contact frame 2 to pass through and install.

[0017] Through the above technical solution, contact frame 1 and contact frame 2 use elastic thin plates. When the end block does not contact the radiator profile, it will extend out of the parallel plate for a distance. When the parallel plate approaches and contacts the radiator profile, the end block is pressed and slides until the end is flush with the end of the parallel plate. At this time, the end of contact frame 1 and contact frame 2 facing away from the end block is pushed out from the oblique mouth and deformed in the upward and downward directions, so that the fins can be clamped from the upper and lower directions.

[0018] Furthermore, the active part includes a contact frame 1 and a contact frame 2, a tee shell is installed at one end where the contact frame 1 and the contact frame 2 are connected, an end block is installed at one end of the tee shell facing the radiator profile, a fine-diameter cavity is provided at the tee shell corresponding to the contact frame 1 and the contact frame 2, and a thick-diameter cavity is provided at the tee shell corresponding to the end block.

[0019] Through the above technical solution, the contact frame 1 and the contact frame 2 adopt a hard piston structure. When the end block does not contact the radiator profile, it will extend a distance from the tee shell and the parallel plate. When the parallel plate approaches and contacts the radiator profile, the end block slides under pressure until the end is flush with the end of the parallel plate. At this time, the end block presses the transfer medium in the large-diameter cavity into the small-diameter cavity, pushing the contact frame 1 and the contact frame 2 to extend in the upward and downward directions, so that the fins can be clamped from the upward and downward directions. Compared with the clamping of elastic deformation, this hard contact clamping can improve the stability of the fins and adapt to fast cutting and thicker radiator profiles.

[0020] Furthermore, the mainboards correspond to the support frames one by one, a support plate is installed between the mainboards and the support frames, and the multiple mainboards are fixed to each other through vertical frames. The vertical frames include screws, which pass through the mainboards. The outer sides of the screws are located at the top and bottom ends of the mainboards and are screwed with self-locking nuts through threads.

[0021] Through the above technical solution, the mainboard and the bracket are fixed at the same horizontal height through the support plate. The clamping firmness of the mainboard can be improved as the number of brackets increases. The height and number of the mainboard and the brackets can be adjusted to adapt to different radiator profiles, and the adaptability is strong.

[0022] Furthermore, a butt plate is installed in the middle of the support frame, and the butt plate can slide horizontally along the vertical side wall of the radiator profile. A self-lubricating grinding block is provided at one end of the butt plate that contacts the rotating blade.

[0023] Through the above technical solution, the abutment plate can move horizontally and be adjusted before cutting, so as to be in direct contact with the rotating blade, thereby reducing the vibration of the rotating blade when it rotates at high speed and contacts the radiator profile, reducing noise, reducing the horizontal vibration deviation of the rotating blade, and improving the smoothness of the cut surface.

[0024] Furthermore, the shearing machine also includes a moving frame, and the positioning frame 1 is installed on the moving frame. The moving frame can fix the positioning frame 1 at a position at the same height as the positioning frame 2. The moving frame can drive the positioning frame 1 to move away from the rotating blade, and the rotating disc knife group is installed with a shell avoiding the position of the moving frame.

[0025] Through the above technical scheme, the moving frame can clamp the right end of the radiator profile when positioning the radiator profile. After cutting, the right end of the radiator profile will become an independent aluminum profile product. The moving frame is away from the rotating blade, which can facilitate the removal of the aluminum profile product. The outer shell plays an anti-splash protection role during cutting. The moving frame is away from the rotating blade and can also facilitate the cleaning of debris inside the outer shell that has not been discharged from the slag discharge port. In order to facilitate the determination of the cleaning time, an inspection door with a glass panel is set at the front of the outer shell for convenient maintenance.

[0026] Furthermore, the shearing machine also includes a conveyor, and a plurality of the conveyors are provided, all of the conveyors are located on the same straight line, and the conveyors are provided with rollers in contact with the bottom surface of the radiator profile.

[0027] Through the above technical scheme, the conveyor is equipped with rollers, which can carry out automatic loading, and guide plates with horizontally bent ends are arranged on the front and rear sides of the rollers, which are interlocked with the convex strips on the bottom surface of the radiator profile. This can ensure that the radiator profile will not be lifted upward by the rollers when it moves horizontally, and can also be coordinated to ensure that the radiator profile will not twist back and forth, thereby improving the loading accuracy.

[0028] The beneficial effects of the present invention are as follows:

[0029] (1) The present invention provides a positioning frame, which can be used for positioning and clamping before cutting the radiator profile. In order to offset the downward pressure of the rotating blade of the rotating disc shearing machine on the radiator profile, the support frame is pressed against the free end of the fin, and adopts a clamping support in the up and down directions, which can avoid disordered vibration and compression deformation of the free end of the fin during cutting, prevent stress fatigue or even fracture at the root of the fin during cutting, and reduce the defective rate of the product fin;

[0030] (2) The present invention improves the positioning frame, and the mainboard is used as the main contact member during clamping. Multiple stacked frames can ensure stable clamping and prevent the radiator profile from being twisted due to horizontal pressure at different heights. The support frame is located at the same height as the mainboard and a distance is left between the mainboards, which can assist the mainboard in making multi-point contact with the radiator profile, ensure the horizontal positioning of the radiator profile, and improve the positioning accuracy.

[0031] (3) The present invention improves the rotary disc knife group and the shearing machine. When arranging the rotary disc knife group, a special-shaped overhead seat is used as a base to install the motor and the rotary blade. This can ensure the smooth up and down movement of the rotary disc knife group without affecting the loading of materials. After cutting, the combined design of the fixed frame and the movable frame of the shearing machine can be used to flexibly unload materials, thereby having good practicality.

[0043] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0044] like Figure 1 - Fig.10 As shown, this embodiment provides a cutting device for processing radiator aluminum profiles, including a shearing machine 1 and a rotating disc knife group 2. The shearing machine 1 is an assembled frame that can provide a stable installation space and a cutting operation position. The rotating disc knife group 2 is an active component that can cut and segment the radiator profile 3 to obtain a product of a required length.

[0045] For the overhead seat 22, refer to Figure 3 and Figure 4 , the overhead seat 22 connects the shearing machine 1 and the rotating disc knife group 2, and a motor 23 is installed in the middle of the overhead seat 22. The motor 23 is used to drive the rotating blade 21 to rotate. Specifically, the overhead seat 22 is mountain-shaped, and hydraulic cylinders are installed at the right front corner and the left rear corner of the overhead seat 22 so that the overhead seat 22 can drive the rotating disc knife group 2 to move vertically in the height direction. In addition, in order to avoid the horizontal twisting of the overhead seat 22, vertical rods can be installed at the left front corner and the right rear corner for sliding guidance. At the same time, in order to avoid the position of the radiator profile 3, the left front position of the overhead seat 22 is avoided backward for a distance to ensure that the horizontal feeding of the radiator profile 3 is not disturbed. It should be emphasized that in order to perform a thorough cutting, the shearing machine 1 is provided with a slag discharge port 13 corresponding to the rotating blade 21. The circular rotating blade 21 can move downward into the slag discharge port 13 for a distance, so that the horizontal tangent length of the rotating blade 21 exposed at the slag discharge port 13 is greater than the front and rear width of the radiator profile 3, and the radiator profile 3 is completely cut off;

[0046] For radiator profile 3, refer to Figure 6, the radiator profile 3 is placed between the shearing machine 1 and the rotating disc cutter group 2, and the radiator profile 3 is conveyed to the right so as to be cut by the rotating blade 21, that is, referring to Figure 4 The rotating blade 21 of the rotating disc knife group 2 cuts the radiator profile 3 into a main body 31 to be cut and an aluminum profile finished product 35. At the same time, in order to meet the heat dissipation requirements, the main body 31 to be cut and the aluminum profile finished product 35 have parallel arranged fins 32. The fins 32 are stacked up and down. The fins 32 are used to increase the contact area with the air and improve the heat dissipation effect. Therefore, a horizontal gap 33 with a single-side opening is formed between the fins 32. The horizontal gap 33 is a subordinate structure after the horizontal fins 32 are set, which can facilitate the passage of air;

[0047] Regarding the positioning frame 1 4 and the positioning frame 2 5, refer to Figure 4 The positioning frame 1 4 and the positioning frame 2 5 are used to clamp the main body 31 to be cut and the finished aluminum profile 35. The positioning frame 1 4 and the positioning frame 2 5 have the same structure except for the difference in the installation position. At the same time, the positioning frame 1 4 and the positioning frame 2 5 are respectively fixed on the top surface of the shearing machine 1 close to the main body 31 to be cut and the finished aluminum profile 35 close to the rotating blade 21, and are arranged in the same straight line to adapt to the horizontal radiator profile 3, and, with reference to Figure 5 and Figure 7 , the positioning frame 1 4 and the positioning frame 2 5 are located in the horizontal gap 33 and are provided with a main board 54 and a support frame 56. The main board 54 is set to be flush with one end of the radiator profile 3 to increase the contact area. The support frame 56 is translated on the main board 54 and pressed against the vertical side walls of the main body 31 to be cut and the finished aluminum profile 35 to stably clamp the radiator profile 3. At the same time, because one end of the fin 32 is fixed to the entire radiator profile 3 to form a fixed end, and the other end of the fin 32 is extended away from the entire radiator profile 3 to form a free end, because the rotating blade 21 used by the rotating disc knife shearing machine cuts through mechanical friction, it is necessary to apply continuous downward pressure to the radiator profile 3 during cutting, and the support frame 56 is pressed against the horizontal side wall of the free end of the fin 32, which can avoid disordered vibration and compressive deformation of the free end of the fin 32 during cutting, prevent stress fatigue or even fracture at the root of the fin 32 during cutting, and reduce the defective rate of the fin 32 position of the product after cutting.

[0048] In a further embodiment, referring to Figure 5The positioning frame 1 4 and the positioning frame 2 5 are arranged symmetrically in pairs, and the positioning frame 1 4 and the positioning frame 2 5 are arranged in pairs, and the radiator profile 3 can be fixed by front and back clamping. There is an installation spacing for the radiator profile 3 to pass between the positioning frame 1 4 and the positioning frame 2 5 in the same group. When loading, the positioning frame 1 4 and the positioning frame 2 5 in the same group are far away from each other to facilitate smooth loading. When cutting, the positioning frame 1 4 and the positioning frame 2 5 in the same group are close to each other to stably cut the radiator profile 3. In order to achieve the horizontal position of the positioning frame 1 4 and the positioning frame 2 5, a translation frame 52 is installed between the positioning frame 1 4 and the positioning frame 2 5 of the same group and the fixed frame 11 of the shearing machine 1, and a driving member 51 is fixedly installed between the translation frame 52 and the fixed frame 11, which has flexible material discharge, clamping and positioning functions. It should be noted that the top surface of the shearing machine 1 is provided with an installation opening corresponding to the translation frame 52, so that the translation frame 52 passes through the top surface of the shearing machine 1 and installs the driving member 51 under the shearing machine 1 to ensure that the top surface of the shearing machine 1 is flat.

[0049] In a further embodiment, when cutting, in order to improve the accuracy of the cutting length, refer to Figure 5 - Figure 7 A notch 34 is provided at the lower edge of the radiator profile 3, and a plurality of equidistant notches 34 are provided and arranged on the front and rear sides. A clamping column is provided at the position corresponding to the notch 34 of the translation frame 52. When the translation frame 52 is close to the radiator profile 3, the clamping column will be embedded in the notch 34, so that fixed-length loading can be conveniently performed. At the same time, a pressing block is provided at the translation frame 52 above the notch 34. When clamping, the bottom surface of the pressing block will contact the horizontal top surface of the notch 34 of the radiator profile 3, pressing the radiator profile 3 downward, thereby improving the firmness of the clamping and ensuring that the radiator profile 3 will not move horizontally during cutting. A round chamfer is provided at the edge of the pressing block to prevent the pressing block from being stuck by the vertical side wall of the radiator profile 3.

[0050] In a further embodiment, referring to Figure 5 and Figure 7The support frame 56 is provided with a plurality of horizontal gaps 33 formed between the fins 32. The support frame 56 includes parallel plates 561 and an action member. The parallel plates 561 of the support frame 56 are located at the elevated position of the main board 54 and form a horizontal distance with the main board 54. The parallel plates 561 can assist the main board 54 to press against the vertical side walls of the main body 31 to be cut and the finished aluminum profile 35. Through the multi-point pressing and clamping in the horizontal direction, the clamping level of the radiator profile 3 is ensured to avoid torsion and tilting in the front and rear directions. At the same time, the parallel plates 561 There are two upper and lower parts, and an installation space is formed in the middle. The acting part is installed in the installation space. The acting part does not contact the fin 32 before clamping to avoid scratching the outer surface of the fin 32 during the clamping process. The acting part can be deformed when the parallel plate 561 is pressed against the vertical side walls of the main body 31 to be cut and the finished aluminum profile 35. After the acting part is deformed, the acting part clamps the fin 32 from the top and bottom after clamping, and presses and contacts with the horizontal side wall of the free end of the fin 32 to avoid the fin 32 from bending and deforming up and down, and reduce stress fatigue caused by vibration and downward pressure.

[0051] In a further embodiment, referring to Fig. 9 The working parts include a contact frame 1 564 and a contact frame 2 565. The contact frame 1 564 and the contact frame 2 565 are made of elastic thin plates. The contact frame 1 564 and the contact frame 2 565 are connected to each other at one end and an end block 563 is installed to form a shape similar to "<", and the tip is toward the contact frame 1 564 and the contact frame 2 565. The elastic thin plate, when the end block 563 does not contact the radiator profile 3, it will extend out of the parallel plate 561 for a distance (not shown in the figure), and at the same time, the contact frame 1 564 and the contact frame 2 565 are back to the end block The ends of the contact frames 563 are far away from each other, and the parallel plate 561 is provided with an oblique opening 562 for the contact frame 1 564 and the contact frame 2 565 to pass through and install. When the parallel plate 561 approaches and contacts the radiator profile 3, the end block 563 is pressed and slides until the end is flush with the end of the parallel plate 561. At this time, the ends of the contact frames 1 564 and the contact frame 2 565 facing away from the end block 563 are pushed out from the oblique opening 562 to deform in the upward and downward directions, so that the fin 32 can be clamped from the upward and downward directions to resist the downward pressure applied by the rotating blade 21 on the free end of the fin 32.

[0052] In a further embodiment, referring to Fig.10The acting member includes a contact frame 1 564 and a contact frame 2 565. The contact frame 1 564 and the contact frame 2 565 adopt a hard piston structure. A three-way shell 566 is installed at one end of the contact frame 1 564 and the contact frame 2 565. The three-way shell 566 contains hydraulic oil or other transmission medium. The three-way shell 566 is installed at one end facing the radiator profile 3. The three-way shell 566 is provided with a large diameter cavity 567 corresponding to the end block 563. The three-way shell 566 is provided with a small diameter cavity 568 corresponding to the contact frame 1 564 and the contact frame 2 565. This different inner diameter The chamber design can allow the contact frame 1 564 and the contact frame 2 565 to move a longer distance accordingly when the end block 563 moves laterally slightly, ensuring that the contact frame 1 564 and the contact frame 2 565 can be sufficiently away from the fin 32 in the shortened state, and the upper and lower multi-layer contact frames 1 564 and 2 565 can clamp the fin 32 from the upper and lower directions in the extended state. Compared with the clamping by elastic deformation, this hard contact clamping can improve the stability of the fin 32, adapt to fast cutting and thicker radiator profiles 3, and can resist the large downward pressure of the rotating blade 21.

[0053] In a further embodiment, referring to Figure 7 and Figure 8 The main board 54 corresponds to the support frame 56 one by one, and the main board 54 and the support frame 56 are fixed at the same horizontal height through the support plate 55. The multiple main boards 54 are fixed to each other through the vertical frame 53. As the number of the main boards 54 increases, the clamping firmness can be improved. The vertical frame 53 includes a screw rod, which runs through the main board 54. The outer side of the screw rod is located at the top and bottom ends of the main board 54 and is screwed with self-locking nuts through threads. When adapting to different radiator profiles 3, the height and number of the main board 54 and the support frame 56 can be adjusted, and the adaptability is strong.

[0054] In a further embodiment, referring to Figure 8 A butt plate 57 is installed in the middle of the support frame 56. A rectangular opening is provided in the middle of the butt plate 57, and a bolt passes through the opening. The butt plate 57 can be moved horizontally left and right by loosening the bolt. A self-lubricating grinding block is provided at the end of the butt plate 57 that contacts the rotating blade 21. The self-lubricating grinding block is preferably made of graphite. The position is adjusted before cutting so that the self-lubricating grinding block is in direct contact with the vertical end face of the rotating blade 21. It should be noted that a large pre-pressure should not be applied to avoid the rotating blade 21 from rotating smoothly. For example, a spring can be installed between the butt plate 57 and the self-lubricating grinding block, and the elastic deformation of the spring is used to store energy to generate pre-pressure to ensure that the contact surface pressure with the rotating blade 21 is controllable. The self-lubricating grinding block is arranged at the edge of the rotating blade 21 away from the rotation center to reduce the horizontal vibration of the edge position of the rotating blade 21 at high speed rotation and the moment of contacting and cutting through the radiator profile 3, thereby reducing noise. At the same time, the horizontal vibration offset of the rotating blade 21 can also be reduced, and the smoothness of the cut surface can be improved to ensure product quality.

[0055] In a further embodiment, referring to Figure 1 and Figure 4 In order to improve the convenience of cutting, the shearing machine 1 also includes a moving frame 12, and the positioning frame 14 is installed on the moving frame 12. The moving frame 12 can fix the positioning frame 14 at a position with the same height as the positioning frame 25. The moving frame 12 can clamp the right end of the radiator profile 3 when positioning the radiator profile 3 to prevent the aluminum profile finished product 35 from falling under the action of gravity when the cutting knife is close to breaking, thereby ensuring that the lower part of the cut end surface is smoother. At the same time, the moving frame 12 can drive the positioning frame 14 to move away from the rotating blade 21. After cutting, the right end of the radiator profile 3 will become an independent aluminum profile finished product 35. The moving frame 12 is away from the rotating blade 21, so that the aluminum profile finished product 35 can be easily removed;

[0056] It should be emphasized that the above-mentioned movement of the movable frame 12 can be translation, with a horizontally arranged hydraulic cylinder as a power source, and the moving distance is greater than the horizontal length of the finished aluminum profile 35, so as to smoothly remove the finished aluminum profile 35 horizontally;

[0057] The above-mentioned moving frame 12 can also be moved by rotation. A rotating driving device (stepping motor, hydraulic motor, etc.) is installed at the lower part of the moving frame 12 near the rotating blade 21. After cutting, the moving frame 12 and the finished aluminum profile 35 are driven to rotate downward clockwise at least ninety degrees as a whole. The horizontal finished aluminum profile 35 can be converted into a vertical one or the top end is tilted to the right, and the material can be taken out upward to achieve unloading, avoiding bumps and wear during unloading, and is suitable for products with a thin overall thickness or high requirements for appearance.

[0058] The movement of the movable frame 12 can also be a combination of translation and rotation. The rotation driving device is installed at the end of the movable frame 12 away from the rotating blade 21. The rotation driving device is driven to translate by a horizontally arranged hydraulic cylinder. After translation, the counterclockwise swing can tilt the left end of the finished aluminum profile 35 downward. The finished aluminum profile 35 can slide out to the lower left under the action of gravity to complete automatic unloading. No other actions or equipment are required to cooperate with unloading, thereby increasing the unloading speed and reducing the equipment cost.

[0059] It should be noted that, refer to Figure 2 and Figure 3 The rotating disc knife group 2 is installed with a shell at a position away from the moving frame 12, and the shell plays a splash protection role during cutting. The moving frame 12 is away from the rotating blade 21, which can also facilitate the cleaning of debris inside the shell that is not discharged downward from the slag discharge port 13. In order to facilitate the determination of the cleaning time, an inspection door with a glass plate is provided at the front of the shell, which is convenient for maintenance.

[0060] In a further embodiment, referring to Figure 2 , Figure 3 and Figure 6The shearing machine 1 also includes a conveyor 6, and a plurality of conveyors 6 are provided for automatic loading. All conveyors 6 are located in the same straight line. The conveyor 6 has rollers, and guide plates with horizontally bent ends are arranged on the front and rear sides of the rollers, which are interlocked with the convex strips on the bottom surface of the radiator profile 3. During transportation, the conveyor 6 is provided with rollers in contact with the bottom surface of the radiator profile 3, which can ensure that the radiator profile 3 will not be lifted up by the rollers when it moves horizontally, and can also be coordinated to ensure that the radiator profile 3 will not twist back and forth, thereby improving the loading accuracy.

[0061] The working principle of this embodiment is as follows:

[0062] When loading, align the convex strip on the bottom of the radiator profile 3 with the guide plate of the conveyor 6, push the radiator profile 3 horizontally to the right until the roller of the conveyor 6 contacts the bottom of the radiator profile 3, and the roller rotates to automatically load the radiator profile 3 to the right;

[0063] During positioning, the radiator profile 3 moves until the distance of the right end passing over the rotating blade 21 reaches the required length of the product. At this time, the right end of the radiator profile 3 is in the position of the moving frame 12. The number and spacing of the main boards 54 are adjusted by the vertical frame 53 to adapt to the position of the fins 32 of the radiator profile 3. The translation frame 52 drives the main boards 54 of the positioning frame 1 4 and the positioning frame 2 5 to approach each other and contact the vertical side wall of the radiator profile 3. The support frame 56 and the main board 54 clamp the radiator profile 3 from the front and back sides. The clamping column of the translation frame 52 is embedded in the notch 34 of the radiator profile 3 to ensure that the radiator profile 3 is straight and will not move left and right.

[0064] Before cutting, the position of the abutment plate 57 is adjusted so that the self-lubricating grinding block is in direct contact with the vertical end face of the rotating blade 21, and the contact point between the self-lubricating grinding block and the rotating blade 21 is at the edge of the rotating blade 21, thereby reducing the horizontal vibration of the edge of the rotating blade 21 when it rotates at high speed, contacts and cuts through the radiator profile 3 at the moment;

[0065] During cutting, the overhead seat 22 drives the rotating blade 21 downward, exerting continuous downward pressure on the radiator profile 3, and the support frame 56 is pressed against the horizontal side wall of the free end of the fin 32, which can avoid disordered vibration and compression deformation of the free end of the fin 32 during cutting, prevent stress fatigue or even fracture at the root of the fin 32 during cutting, and reduce the defective rate of the position of the fin 32 of the product after cutting, until the radiator profile 3 is cut to obtain an independent main body 31 to be cut and an aluminum profile finished product 35;

[0066] When unloading, the movable frame 12 is away from the rotating blade 21, and sufficient unloading space can be formed by the positioning frame 14 and the aluminum profile product 35 away from the rotating blade 21, and the angle and state of the aluminum profile product 35 can be changed to facilitate the removal of the aluminum profile product 35;

[0067] After completing the above-mentioned action process, the loading, cutting and unloading actions can be repeated to continuously produce finished aluminum profiles 35.

[0068] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
