Description

Technical Field

[0001] This invention relates to the technical field of cutting equipment, specifically to a CNC cutting equipment for radiator processing and its operating method. Background Technology

[0002] A heat sink is a device for dissipating heat from electronic components in electrical appliances. They are usually made of aluminum alloy, brass, or bronze and can be in the form of plates, sheets, or multiple sheets. Generally, when using a heat sink, a layer of thermal grease is applied to the contact surface between the electronic component and the heat sink so that the heat generated by the component can be more effectively conducted to the heat sink and then dissipated into the surrounding air.

[0003] Chinese patent document CN209503000U discloses a cutting tool for machining heat sinks. The tool includes a fixed plate, an extension plate, and a tool holder. The fixed plate has a fixing hole inside. The extension plate is located at the end of the fixed plate, and the extension plate and the fixed plate intersect at a 90-degree angle. The extension plate has a sliding groove inside, and an adjusting bolt is located at the upper part of the sliding groove. The tool holder includes a sliding plate, a tool plate, a cutting blade, and a fixing bolt. One end of the sliding plate is movably disposed within the sliding groove, and the end of the adjusting bolt passes through the extension plate. The blade plate is in contact with the outer wall of the sliding plate; the other end of the sliding plate is connected to the cutting tool plate, and the cutting tool plate and the sliding plate intersect at a 90-degree angle; the cutting tool plate is provided with a groove inside, and the grooves are arranged sequentially along the length of the cutting tool plate; the fixing bolt is provided at the upper part of the groove; the cutting tool is matched and arranged in the groove, and the end of the fixing bolt penetrates through the groove and contacts the outer wall of the cutting tool; the cutting tool plate is provided with a scale line at the upper part, and the scale line and the groove are arranged one-to-one;

[0004] However, the above-mentioned solution requires the synchronous operation of multiple axes of the lathe to complete the processing of the radiator, which results in the need for a multi-directional drive structure for the equipment, making it inconvenient for the equipment to be controlled by the circuit, and also making it more troublesome for the staff to inspect the circuit. Therefore, the present invention proposes a CNC cutting equipment for radiator processing and its operating method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a CNC cutting device for radiator processing and its operating method, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a CNC cutting machine for radiator processing, comprising:

[0007] The processing table has legs on its bottom surface and a set of primary slots and a secondary slot on its surface. The primary slots are symmetrically arranged on both sides of the secondary slots. A front mounting seat and a rear mounting seat are fixedly installed on the front and rear ends of the lower surface of the processing table, respectively. A primary drive structure is provided between the front mounting seat and the rear mounting seat.

[0008] The material loading platform is driven back and forth by a primary drive structure. The profile to be processed is positioned in the profile groove on the material loading platform. A screw seat is fixedly installed on the front end of the material loading platform. A positioning screw is screwed onto the screw seat. A rotating handle is fixedly connected to the front end of the positioning screw. An adapter rod is integrally formed on the rear end of the positioning screw. A clamping plate is rotatably connected to the adapter rod. The clamping plate is used to position and fix the profile to be processed.

[0009] The cutting tool is fixedly connected to the rear end of the processing table, and a hydraulic mechanism mounting base is fixedly installed on the hydraulic mechanism mounting base. The cutting tool is fixedly connected to the telescopic rod of the hydraulic mechanism, and the cutting tool is driven by the hydraulic mechanism. The upper part of the profile is cut into multiple heat sinks by the cutting tool.

[0010] Preferably, a primary guide rod is fixedly installed between the front mounting base and the rear mounting base. The primary drive structure includes a primary guide rod, a transmission screw, and a servo motor. The primary guide rod is fixed between the front mounting base and the rear mounting base. The transmission screw is rotatably installed between the front mounting base and the rear mounting base. The servo motor is fixed to the lower side of the processing table, and the transmission screw is driven by the servo motor.

[0011] Preferably, a primary guide seat and a lead screw seat are fixedly connected to the lower surface of the loading platform. The primary guide seat and the lead screw seat are respectively set through a primary slot and a secondary slot. The primary guide seat has a primary guide rod hole and is movably mounted on a primary guide rod. The lead screw seat has a lead screw hole and the transmission lead screw is configured to cooperate with the lead screw hole.

[0012] Preferably, a primary mounting base is provided at the middle position of the machining table, and a secondary mounting base is provided at the rear position of the machining table. A set of primary and secondary mounting bases are symmetrically arranged, and a secondary guide rod is fixedly installed between the primary and secondary mounting bases. The front end of the secondary guide rod is inclined downward. Secondary guide rod seats are fixedly connected to both sides of the cutting tool. The secondary guide rod seat has a secondary guide rod hole and is movably mounted on the secondary guide rod.

[0013] Preferably, the cutting tool includes a main tool holder and a cutting head. The secondary guide rod holder is integrally formed with the main tool holder. The main tool holder has a cutting head groove. A clearance groove is formed at the bottom of the cutting head groove. A guide screw is fixedly connected to the bottom of the clearance groove. A primary guide hole is formed on the upper surface of the cutting head. A nut groove is formed at the upper end of the primary guide hole. A limit nut is fixedly tightened on the upper end of the guide screw. The limit nut is used to restrict the movement position of the cutting head.

[0014] Preferably, the guide screw is vertically upward and the inner end face of the cutter head is vertical. The guide screw passes through the primary guide hole. A spring groove is formed on the lower surface of the cutter head. A support spring is fixedly connected to the bottom of the spring groove. When the support spring is in the reset state, the cutter head is lifted up. At this time, the cutter head exerts an upward force on the root of the heat sink and bends the heat sink to a vertical state.

[0015] Preferably, an installation beam is fixedly installed on the upper surface of the processing table, and a force-bearing component is fixedly installed on the crossbeam of the installation beam. The force-bearing component includes a main force-bearing seat and a secondary force-bearing seat. The main force-bearing seat is fixedly connected to the installation beam. The front end face of the main force-bearing seat is vertically oriented, and a wedge-shaped surface is formed at the lower corner of the front end face of the main force-bearing seat. A movable groove is formed at the front end of the main force-bearing seat, and a threaded hole is formed at the bottom of the groove. The cross-section of the movable groove is convex. The cross-sectional dimensions of the secondary force-bearing seat match the cross-sectional dimensions of the movable groove, and the secondary force-bearing seat is movably disposed in the movable groove. A primary movable hole is formed at the outer end of the secondary force-bearing seat, and a secondary movable hole is formed at the inner end of the secondary force-bearing seat.

[0016] Preferably, a return spring is sleeved on the limiting bolt. When the return spring is in the reset state, the outer end face of the secondary force-bearing seat is flush with the front end face of the main force-bearing seat. At this time, the nut of the limiting bolt abuts against the bottom of the primary movable hole. When the front end face of the secondary force-bearing seat is subjected to force, the secondary force-bearing seat is completely retracted into the movable groove.

[0017] Preferably, when the cutting tool completes the cutting of a single heat sink, the inner end face of the cutting tool head is flush with the front end face of the main force bearing seat.

[0018] A method for operating a CNC cutting machine for radiator processing is disclosed. This method controls the operation of the CNC cutting machine. The method involves first positioning the profile to be processed in a profile groove on a loading platform. Then, a servo motor is driven to move the loading platform forward. A hydraulic mechanism then moves forward, causing the cutting tool to move forward, thereby cutting the profile using the cutting head. When a single radiator fin is finished cutting, the cutting head loses its secondary force. The force of the seat lifts the cutter head under the action of the support spring, causing the cutter head to exert an upward force on the root of the heat sink, bending the heat sink to a vertical position. When the hydraulic mechanism returns, the cutter head exerts a force on the secondary support seat, causing the secondary support seat to retract into the movable groove. This causes the cutter head to exert a force on the wedge-shaped surface on the main support seat, causing the cutter head to retract into the cutter head groove. Then, by driving the servo motor, the loading platform is driven forward, and the above actions are repeated to complete the processing of all the heat sinks on the heat sink.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. By setting up a CNC cutting equipment for radiator processing, which consists of a processing table, a loading platform and a cutting tool, the upper surface of the profile is cut into continuous heat sinks by the cutting tool. The cutting tool is set up to consist of a main tool holder and a cutting head. After the hydraulic mechanism moves, the cutting head can be lifted by the support spring, thereby realizing automatic alignment of the heat sink, reducing the power source on the equipment and facilitating daily inspection and maintenance of the equipment.

[0021] 2. By setting a mounting beam on the machining table, and setting a force-bearing component consisting of a main force-bearing seat and a secondary force-bearing seat on the mounting beam, and elastically connecting the secondary force-bearing seat to the main force-bearing seat through a return spring, the force-bearing component can easily control the position of the cutting head, and the cutting tool can easily return to its original position.

The primary slots 4 are symmetrically arranged on both sides of the secondary slots 5. A front mounting seat 6 and a rear mounting seat 7 are fixedly installed at the front and rear ends of the lower surface of the machining table 1, respectively.

The upper part of the profile 19 is cut into multiple heat sinks 24 by the cutting tool 3.

[0041] A primary guide rod 8 is fixedly installed between the front mounting base 6 and the rear mounting base 7. The primary drive structure includes the primary guide rod 8, the transmission screw 9, and the servo motor. The primary guide rod 8 is fixed between the front mounting base 6 and the rear mounting base 7. The transmission screw 9 is rotatably installed between the front mounting base 6 and the rear mounting base 7. The servo motor is fixed on the lower side of the processing table 1, and the transmission screw 9 is driven by the servo motor.

A screw hole is opened on the screw seat 11, and the transmission screw 9 is matched with the screw hole.

[0042] A primary mounting base 12 is located in the middle of the machining table 1, and a secondary mounting base 13 is located at the rear of the machining table 1. A set of primary mounting bases 12 and secondary mounting bases 13 are symmetrically arranged, and a secondary guide rod 14 is fixedly installed between the primary mounting bases 12 and the secondary mounting bases 13. The front end of the secondary guide rod 14 is inclined downwards. Secondary guide rod seats 15 are fixedly connected to both sides of the cutting tool 3. Secondary guide rod seats 15 have secondary guide rod holes and are movably mounted on the secondary guide rod 14. By setting up a CNC cutting equipment for radiator processing, which consists of a processing table 1, a material loading platform 2 and a cutting tool 3, the upper surface of the profile 19 is cut into continuous heat sink fins 24 by the cutting tool 3. The cutting tool 3 is set up to consist of a main tool holder 25 and a cutting head 26. After the hydraulic mechanism 17 moves, the cutting head 26 can be lifted by the support spring 33, thereby realizing automatic alignment of the heat sink fins 24, reducing the power source on the equipment and facilitating daily inspection and maintenance of the equipment.

[0043] In Example 2, based on Example 1, the cutting tool 3 includes a main tool holder 25 and a tool head 26. A secondary guide rod holder 15 is integrally formed with the main tool holder 25. A tool head groove 27 is formed on the main tool holder 25. A clearance groove 28 is formed at the bottom of the groove 27. A guide screw 29 is fixedly connected to the bottom of the clearance groove 28. A primary guide hole is formed on the upper surface of the tool head 26. A nut groove 31 is formed at the upper end of the primary guide hole. A limit nut 30 is fixedly tightened at the upper end of the guide screw 29. 0 is used to restrict the movement position of the cutter head 26. The guide screw 29 is set vertically upward, and the inner end face of the cutter head 26 is set vertically. The guide screw 29 passes through the first-stage guide hole. A spring groove 32 is opened on the lower surface of the cutter head 26. A support spring 33 is fixedly connected to the bottom of the spring groove 32. When the support spring 33 is in the reset state, the cutter head 26 is lifted up. At this time, the cutter head 26 exerts an upward force on the root of the heat sink 24 and bends the heat sink 24 to a vertical state.

[0044] A mounting beam 34 is fixedly installed on the upper surface of the processing table 1. A force-bearing component 35 is fixedly installed on the crossbeam of the mounting beam 34. The force-bearing component 35 includes a main force-bearing seat 36 and a secondary force-bearing seat 37. The main force-bearing seat 36 is fixedly connected to the mounting beam 34. The front end face of the main force-bearing seat 36 is vertically oriented, and a wedge-shaped surface 45 is provided at the lower corner of the front end face of the main force-bearing seat 36. A movable groove 38 is provided at the front end of the main force-bearing seat 36, and a threaded hole 39 is provided at the bottom of the groove. The cross-section of the movable groove 38 is convex. The cross-sectional dimensions of the secondary force-bearing seat 37 match the cross-sectional dimensions of the movable groove 38, and the secondary force-bearing seat 37 is movably disposed within the movable groove 38. The outer side of the secondary force-bearing seat 37... The secondary force-bearing seat 37 has a primary movable hole 40 at one end and a secondary movable hole 41 at the inner end. The secondary movable hole 41 and the primary movable hole 40 are connected by a secondary guide hole. A limit bolt 42 is screwed into the threaded hole 39. The screw of the limit bolt 42 passes through the secondary guide hole and the secondary movable hole 41. A return spring 43 is fitted on the limit bolt 42. When the return spring 43 is in the return state, the outer end face of the secondary force-bearing seat 37 is flush with the front end face of the primary force-bearing seat 36. At this time, the nut of the limit bolt 42 abuts against the bottom of the primary movable hole 40. When the front end face of the secondary force-bearing seat 37 is subjected to force, the secondary force-bearing seat 37 is completely retracted into the movable groove 38.

[0045] When the cutting tool 3 completes the cutting of the single heat sink 24, the inner end face of the tool head 26 is flush with the front end face of the main force seat 36. By setting a mounting beam 34 on the machining table 1, and setting a force-bearing component 35 composed of the main force seat 36 and the secondary force seat 37 on the mounting beam 34, and elastically connecting the secondary force seat 37 to the main force seat 36 through a return spring 43, it is convenient for the force-bearing component 35 to control the position of the tool head 26, and it is also convenient for the cutting tool 3 to perform the return motion.

[0046] Example 3, based on Example 2, provides an operation method for a CNC cutting device for radiator processing. This method controls the operation of the CNC cutting device. The method involves first positioning the profile 19 to be processed in the profile groove 18 on the loading platform 2. Then, by driving a servo motor, the loading platform 2 is moved forward. The hydraulic mechanism 17 then moves forward, causing the cutting tool 3 to move forward, thereby cutting the profile 19 through the cutting head 26. When a single radiator 24 is finished cutting, the cutting head 26 loses its secondary support 3. The force of the hydraulic mechanism 17 causes the cutting head 26 to be lifted by the support spring 33, thereby generating an upward force on the root of the heat sink 24 to bend the heat sink 24 to a vertical position. When the hydraulic mechanism 17 returns, the cutting head 26 exerts a force on the secondary support seat 37, causing the secondary support seat 37 to retract into the movable groove 38. This causes the cutting head 26 to exert a force on the wedge-shaped surface 45 on the main support seat 36, thereby causing the cutting head 26 to retract into the cutting head groove 27. Then, by driving the servo motor, the loading platform 2 is driven forward, and the above actions are repeated to complete the processing of all the heat sinks 24 on the heat sink.

8. The CNC cutting equipment for radiator processing according to claim 7, characterized in that: When the cutting tool (3) cuts a single heat sink (24), the inner end face of the cutting head (26) is flush with the front end face of the main force seat (36).

9. An operating method for a CNC cutting machine used for radiator processing, characterized in that: The operation method of the CNC cutting equipment for radiator processing is used to control the operation of any one of the CNC cutting equipment for radiator processing according to claims 1-8. The operation method is as follows: first, the profile (19) to be processed is positioned in the profile groove (18) on the loading platform (2), and then the loading platform (2) is moved forward by driving the servo motor. Then, the hydraulic mechanism (17) moves forward, thereby driving the cutting tool (3) to move forward, so that the profile (19) is cut by the cutting head (26). When a single heat sink (24) is cut, the cutting head (26) loses the force of the secondary force seat (37), thereby supporting the spring (33) Under the action of the hydraulic mechanism (17), the cutting head (26) is lifted up, so that the cutting head (26) exerts an upward force on the root of the heat sink (24) to bend the heat sink (24) to a vertical state. When the hydraulic mechanism (17) returns, the cutting head (26) exerts a force on the secondary force seat (37), so that the secondary force seat (37) is retracted into the movable groove (38), so that the cutting head (26) exerts a force on the wedge surface (45) on the main force seat (36), so that the cutting head (26) is retracted into the cutting head groove (27). Then, by driving the servo motor, the loading platform (2) is driven forward and the cycle is repeated to complete the processing of all the heat sinks (24) on the heat sink.
