The rear end of the conveying roller is connected to a motor, and the rotation of the conveying roller is controlled by the motor.

[0004] However, during the continuous processing of copper strips by the milling machine, due to the frictional heat and cutting deformation heat generated by the cutting tool and the workpiece during the cutting process, especially during high-speed cutting, the surface temperatures of the cutting tool and the workpiece may increase, thereby reducing the tool life. There may also be cases where the chips of some copper strips adhere to the surface of the cutting tool due to heat, which in turn affects the processing quality of the copper strips. Summary of the Utility Model

[0005] The utility model discloses a continuous milling machine for copper strip processing, aiming to solve the technical problem that during the continuous processing of copper strips by the milling machine, due to the frictional heat and cutting deformation heat generated by the cutting tool and the workpiece during the cutting process, especially during high-speed cutting, the surface temperatures of the cutting tool and the workpiece may increase, thereby reducing the tool life. There may also be cases where the chips of some copper strips adhere to the surface of the cutting tool due to heat, which in turn affects the processing quality of the copper strips.

[0006] To achieve the above object, the utility model adopts the following technical solutions:

[0007] A continuous milling machine for copper strip processing, including a base body, a copper strip, and a milling machine body. The milling machine body includes a milling cutter, and the milling cutter is installed above the base body. The milling cutter is used for milling the copper strip, and further includes:

[0008] A conveying mechanism: located on the outer wall of one opposite side of the base body;

[0009] Cooling mechanism: Located on both sides of the milling cutter, the cooling mechanism includes four sliders. An installation frame is provided on the outer wall of the top of the slider. One end of adjacent two installation frames is fixedly connected with a cold water tank. A water storage cavity is arranged inside the cold water tank. Seven high-pressure nozzles are installed on one side of the cold water tank. The two cold water tanks and adjacent two installation frames are symmetrically arranged about the center line of the base body on the left and right. The milling cutter is located between the two cold water tanks. A water collecting box is arranged on the inner wall of the opposite side of the base body and below the conveying mechanism.

[0010] Adjusting mechanism: Located above the conveying mechanism.

[0011] During use, first control the position of the conveying mechanism through the adjusting mechanism, so as to realize the movement of the copper strip and the clamping and limiting of the copper strip, which is convenient for subsequent continuous processing of the surface of the copper strip. Then the milling cutter on the milling machine body is located between the two cold water tanks and processes the surface of the copper strip. At the same time, the coolant in the two cold water tanks is sprayed out through the high-pressure nozzles to cool the surface of the milling cutter and the copper strip, and wash away the chips adhered to the surface of the milling cutter. Then the coolant carries part of the chips and flows into the water collecting box together, which is collected and processed by the staff uniformly, so as to avoid the splashing of metal chips and affect the processing quality of the copper strip. This device can reduce the wear of the milling cutter at high temperature, extend the service life of the milling cutter, reduce the chip adhesion phenomenon, lower the surface roughness of the processing, and improve the dimensional accuracy and shape accuracy of the copper strip.

One end of the two conveying rollers is connected to one inner wall of two of the installation frames through a bearing. An auxiliary roller is connected between adjacent two sliders through a bearing.

[0013] When milling the copper strip, the copper strip can be placed between the auxiliary roller and the conveying roller, and the upper surface and the lower surface of the copper strip are close to the circumferential outer walls of the conveying roller and the auxiliary roller. Then, by adjusting the position of the auxiliary roller through the adjusting mechanism, the distance between it and the conveying roller can be changed, so as to limit and convey copper strips of different thicknesses. And the auxiliary roller can rotate synchronously with the conveying roller under the action of the transmission belt, improving the conveying and processing efficiency.

[0014] In a preferred embodiment, the adjusting mechanism includes four threaded rods, which are connected to the top outer wall of the slider through bearings. A limiting opening is formed in the top of the mounting frame.

[0015] During use, first rotate the threaded rod, so that the slider moves up and down in the mounting frame, and at the same time, it can drive the auxiliary roller, the mounting rack, and the cold water tank to move up and down synchronously. Then, the distance between the auxiliary roller and the conveying roller can be adjusted, so that it can limit and convey copper strip plates of different thicknesses, enhancing the practicability of the device.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Usually, the components of the embodiments of the present application described and marked in the attached drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the attached drawings is not intended to limit the scope of the present application claimed, but only represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0027] A continuous milling machine for copper strip processing disclosed by the present utility model is mainly applied to the process of continuously processing copper strip by a milling machine. During the cutting process, due to the frictional heat and cutting deformation heat generated by the tool and the workpiece, especially during high-speed cutting, it may cause the surface temperature of the tool and the workpiece to rise, thereby reducing the tool life. There may also be a situation where the chips of some copper strips adhere to the tool surface due to heat, which in turn affects the processing quality of the copper strip.

[0028] Refer to Figure 1 , Figure 2 and Figure 3 , a continuous milling machine for copper strip processing, including a base body 1, a copper strip, and a milling machine body. The milling machine body includes a milling cutter 4, and the milling cutter 4 is installed above the base body 1. The milling cutter 4 is used for milling the copper strip, and further includes:

[0029] Conveying mechanism: located on the outer wall of the opposite side of the base body 1;

[0030] Cooling mechanism: Located on both sides of the milling cutter 4, the cooling mechanism includes four sliders 6. An installation frame 8 is provided on the outer wall of the top of the slider 6. One ends of adjacent two installation frames 8 are fixedly connected to form a cold water tank 9. A water storage cavity is provided inside the cold water tank 9. Seven high-pressure nozzles 10 are installed on one side of the cold water tank 9. The two cold water tanks 9 and the adjacent two installation frames 8 are symmetrically arranged about the center line of the base 1 on the left and right. The milling cutter 4 is located between the two cold water tanks 9. A water collecting box 2 is provided on the inner wall of the opposite side of the base 1 and below the conveying mechanism.

[0031] Adjusting mechanism: Located above the conveying mechanism.

[0032] It should be noted that a wear-resistant and high-temperature-resistant coating, such as titanium carbonitride coating, can be coated on the surface of the milling cutter 4 to improve the wear resistance and anti-adhesion ability of the cutter, and reduce the chip adhesion phenomenon.

[0033] Among them, the installation frame 8 is of an arc structure to avoid forming dead corners at the connection with the slider 6, thus affecting the conveyance of the copper strip by the conveying mechanism.

[0034] In the specific implementation process, the spraying directions of the seven high-pressure nozzles 10 are set to be inclined downward. A protective net is provided on the inner wall of one end of the high-pressure nozzle 10. Such a setting facilitates the top-down flushing of the milling cutter 4, reduces the chip adhesion on the surface of the milling cutter 4, and cools and lowers the temperature of the milling cutter 4 and the copper strip in a larger range. The protective net is mainly to prevent chips from entering the inside of the high-pressure nozzle 10, thereby reducing the loss of the high-pressure nozzle 10 and prolonging the service life of the high-pressure nozzle 10.

[0035] Among them, the outer wall of one side of the cold water tank 9 is of an arc structure. An installation pipe 18 is provided on one outer wall of the water collecting box 2. A one-way valve is provided at one end of the installation pipe 18. The arc-shaped sides of the two cold water tanks 9 are close to each other to form an "eight" shape, which can block a part of the chip and coolant splash. When the water collecting box 2 is full, the one-way valve can be opened, and the staff can perform batch filtering treatment on the coolant and part of the metal chips inside.

[0036] Specifically, during use, first, the position of the conveying mechanism is controlled by the adjusting mechanism, so as to move the position of the copper strip and clamp and limit the copper strip, which is convenient for subsequent continuous processing of the surface of the copper strip. Then, the milling cutter 4 on the milling machine body is located between the two cold water tanks 9 and processes the surface of the copper strip. At the same time, the coolant in the two cold water tanks 9 is ejected through the high-pressure nozzles 10 to cool the milling cutter 4 and the surface of the copper strip, and wash away the chips adhered to the surface of the milling cutter 4. Then, the coolant carries part of the chips and flows into the water collecting box 2 together, which is collected and processed by the staff uniformly, thus avoiding the splashing of metal chips and affecting the processing quality of the copper strip. This device can reduce the wear of the milling cutter 4 at high temperatures, extend the service life of the milling cutter 4, reduce the chip adhesion phenomenon, lower the surface roughness of the processing, and improve the dimensional accuracy and shape accuracy of the copper strip board.

[0037] Referring to Figure 1 、 Figure 4 and Figure 5 , in a preferred embodiment, the conveying mechanism includes four mounting frames 3, the four mounting frames 3 are mounted on the outer walls of both sides of the base body 1, the slider 6 is slidably connected to the inner wall of the mounting frame 3, and a mounting groove 7 is formed on the outer wall of the top of the base body 1. One inner wall of two of the mounting frames 3 is provided with a motor 11 near the bottom position, the output shaft of the motor 11 is fixedly connected with a conveying roller 12, one ends of the two conveying rollers 12 are connected to one inner wall of two of the mounting frames 3 through bearings, and an auxiliary roller 13 is connected between adjacent two sliders 6 through a bearing.

[0038] It should be noted that the rotation directions, power and rotational speeds of the two motors 11 are the same, so that the two groups of conveying rollers 12 can rotate synchronously, improving the conveying stability of the copper strip.

[0039] Among them, a fixing plate 15 is provided on the inner wall of the mounting groove 7, a return spring 16 is provided on the outer wall of one side of the fixing plate 15, a movable plate 17 is provided at one end of the return spring 16, one side of the movable plate 17 is of an arc-shaped structure, and a transmission belt 14 is sleeved on the circumferential outer wall of the conveying roller 12, the circumferential outer wall of the auxiliary roller 13 and one side of the movable plate 17. When the adjusting mechanism drives the slider 6 to move upward in the mounting frame 3, the tension of the transmission belt 14 will change. At this time, the movable plate 17 will move a certain amplitude under the cooperation of the return spring 16 and the fixing plate 15. When the auxiliary roller 13 moves upward, the transmission belt 14 squeezes the movable plate 17, so that the return spring 16 is stressed and shortened. When the auxiliary roller 13 moves downward, the movable plate 17 pushes and squeezes the transmission belt 14 under the elastic force of the return spring 16, so that the transmission belt 14 can still maintain effective tension after the auxiliary roller 13 moves.

[0040] Specifically, when milling the copper strip, the copper strip can be placed between the auxiliary roller 13 and the conveying roller 12, and the upper and lower surfaces of the copper strip are close to the circumferential outer walls of the conveying roller 12 and the auxiliary roller 13. Then, by adjusting the position of the auxiliary roller 13 through the adjusting mechanism, the distance between it and the conveying roller 12 can be changed, so that it can limit and convey copper strips of different thicknesses. Moreover, the auxiliary roller 13 can rotate synchronously with the conveying roller 12 under the action of the transmission belt 14 to improve the conveying and processing efficiency.

[0041] Referring to Figure 1 and Figure 4 , in a preferred embodiment, the adjusting mechanism includes four threaded rods 5. The threaded rods 5 are connected to the top outer wall of the slider 6 through bearings. A limiting port is opened at the top of the mounting frame 3. One end of the threaded rod 5 penetrates through the inner wall of the limiting port, and the threaded rod 5 is threadedly connected to the inner wall of the limiting port.

[0042] It should be noted that the bottom of the cold water tank 9 and the topmost circumference of the auxiliary roller 13 are on the same horizontal plane.

[0043] Specifically, during use, first rotate the threaded rod 5, so that the slider 6 moves up and down in the mounting frame 3, and at the same time can drive the auxiliary roller 13 and the mounting bracket 8 and the cold water tank 9 to move up and down synchronously. Then, the distance between the auxiliary roller 13 and the conveying roller 12 can be adjusted, so that it can limit and convey copper strips of different thicknesses, enhancing the practicability of the device.

[0044] Working principle: During use, first control the position of the conveying mechanism through the adjusting mechanism, so as to move the position of the copper strip and clamp and limit the copper strip, facilitating subsequent continuous processing of the surface of the copper strip. Then, the milling cutter 4 on the milling machine body is located between the two cold water tanks 9 and processes the surface of the copper strip. At the same time, the coolant in the two cold water tanks 9 is ejected through the high-pressure nozzles 10 to cool the milling cutter 4 and the surface of the copper strip, and wash away the chips adhered to the surface of the milling cutter 4. Then, the coolant carries some chips and flows into the water collecting box 2 together, which is collected and processed by the staff uniformly, so as to avoid metal chips from splashing and affecting the processing quality of the copper strip.

[0045] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. The substitution may be the substitution of some structures, devices, and method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present invention and its inventive concept should be covered within the protection scope of the present invention.
