[0002] A high-precision double-sided milling machine for copper strip processing is a support device for milling both sides of copper strip. In the copper strip processing industry, double-sided milling of copper strip is an important processing step.

[0003] Existing double-sided milling machines for high-precision copper strip processing have certain drawbacks. These machines encounter numerous problems when processing copper strips. Firstly, due to the softness of the copper strip, it is prone to wobbling during milling, leading to decreased processing accuracy and failing to meet the requirements of high-precision copper strip processing. Secondly, the significant heat generated during milling not only causes thermal deformation of the copper strip, affecting its dimensional accuracy and surface quality, but also accelerates cutter wear, reduces tool life, and increases processing costs. Furthermore, traditional equipment suffers from insufficient stability and significant vibration, further impacting the surface finish and equipment lifespan. Therefore, developing a double-sided milling machine with high processing accuracy and high surface roughness is of significant practical importance.

[0022] like Figure 1-4 As shown, a high-precision double-sided milling machine for copper strip processing includes a main body 1. From left to right and located at the position of the copper strip, a first feeding roller 2, a lower milling mechanism 3, a second feeding roller 4, an upper milling mechanism 5, and a third feeding roller 6 are sequentially installed on the main body 1. The lower milling mechanism 3 is arranged in opposite directions to the upper milling mechanism 5. The lower milling mechanism 3 includes a back roller 7, an inlet guide plate 8, an inlet pressure roller 9, a milling cutter 10, a bearing seat upper and lower fixing mechanism 11, an outlet guide plate 12, an outlet pressure roller 13, a bearing seat left and right fixing mechanism 14, and a chip suction cylinder 15.

[0023] Furthermore, the back roller 7 is located on the upper and lower fixing mechanism 11 of the bearing seat, the milling cutter 10 is located on the left and right fixing mechanism 14 of the bearing seat, the milling cutter 10 is located below the back roller 7, the inlet pressure roller 9 is located on the inlet guide plate 8, and the outlet pressure roller 13 is located on the outlet guide plate 12.

[0024] Furthermore, a baffle 16 is positioned at the upper end of the chip suction cylinder 15, a chip suction fan 19 is installed at the upper part of the inner wall of the chip suction cylinder 15, a chip suction pipe 18 is installed on the chip suction fan 19, a chip suction cover 17 is installed at the top of the chip suction pipe 18, a chip outlet 21 is provided on the outer side of the bottom of the chip suction cylinder 15, and a chip inlet 20 is opened at the upper end of the chip suction cylinder 15.

[0025] Furthermore, the back roller 7 rotates on the upper and lower fixing mechanism 11 of the bearing housing, and the milling cutter 10 rotates on the left and right fixing mechanism 14 of the bearing housing. The back roller 7 and the milling cutter 10 are combined to perform cutting.

[0026] Furthermore, the chip suction cylinder 15 is engaged and positioned with the baffle 16, and the chip suction cylinder 15 is fixed with the chip suction fan 19 by bolts. The chip suction fan 19 drives the chip suction cover 17 to suck up chips and blow them into the inside of the chip suction cylinder 15 through the chip suction pipe 18.

[0027] Furthermore, the copper strip passes sequentially through the positions of the first feeding roller 2, the lower milling mechanism 3, the second feeding roller 4, the upper milling mechanism 5, and the third feeding roller 6, and is milled on both sides by the lower milling mechanism 3 and the upper milling mechanism 5.

[0028] Furthermore, the upper milling mechanism 5 and the lower milling mechanism 3 have the same structure, and the upper milling mechanism 5 and the lower milling mechanism 3 are arranged in opposite directions.

[0029] Furthermore, during operation, the lower milling mechanism 3 uses the back roller 7 and the milling cutter 10 to mill the lower surface of the copper strip.

[0030] Working Principle: This utility model includes a main body 1, a first feeding roller 2, a lower milling mechanism 3, a second feeding roller 4, an upper milling mechanism 5, a third feeding roller 6, a back roller 7, an inlet guide plate 8, an inlet pressure roller 9, a milling cutter 10, a bearing seat upper and lower fixing mechanism 11, an outlet guide plate 12, an outlet pressure roller 13, a bearing seat left and right fixing mechanism 14, a chip suction cylinder 15, a baffle 16, a chip suction hood 17, a chip suction pipe 18, a chip suction fan 19, a chip inlet 20, and a chip outlet 21. It solves the problems of unstable strip, large vibration, and high heat generation in the processing of copper strips by existing equipment, improves the processing accuracy and quality of copper strips, extends the service life of tools, reduces processing costs, provides high-quality raw materials for the next process, and improves the yield and quality grade of rolled products.

[0031] The first feeding roller uses two sets of clamping rollers. The lower roller is fixed, while the upper roller is opened and closed by a hydraulic cylinder. Both rollers are driven by a single vector motor. This ensures both the flatness of the copper strip before entering the milling zone and the stability of the material during the milling process, thereby guaranteeing a high-quality milled surface finish.

[0032] The lower milling mechanism mills the lower surface of the material. To ensure the surface quality of the precision milling, the milling machine is equipped with an auxiliary mechanism to support the precision milling process.

[0033] The second feed roller has the same structure as the first feed roller. The precise coordination of the speed and output of the first and second feed rollers ensures the stability of the material during milling and safeguards high-quality milling.

[0034] The upper milling mechanism mills the upper surface of the material.

[0035] The third feed roller has the same structure as the first two sets of feed rollers. The precise coordination of the speed and output of the second and third feed rollers ensures the stability of the material during milling, safeguarding high-quality milling. Since the three feed rollers have different conveying capacities, the motors are individually controlled to ensure accurate and reasonable output from each roller, increasing the milling speed to 8-20 m / min. Milling removes oxide layers, component segregation, surface scratches, and cracks, reducing material loss and improving yield.

[0036] Back roller

[0037] Driven by a servo motor, the position and level of the back roller are controlled through a composite transmission structure of a high-precision diaphragm coupling and a worm gear. The servo motor provides precise control (±0.01mm accuracy) and is displayed on a digital display. This reduces vibration and improves transmission accuracy. Two servo motors operate on each back roller, allowing for independent adjustment on both the DS and WS sides. The back roller also allows for flexible switching between low and high-speed operation.

[0038] Bearing housing upper and lower fixing mechanism

[0039] When a milling cutter cuts, the material vibrates. The upper and lower fixing mechanisms of the bearing housing can reduce the amplitude of vertical vibration. The fixing mechanism is powered by hydraulic oil, which has a fast response speed, convenient pressure adjustment, and smooth and reliable movement.

[0040] Inlet guide plate

[0041] By guiding the workpiece into the milling area via a preset path, offset or misalignment during machining is avoided, improving milling accuracy. When the workpiece enters the milling machine, the guide plate and the workpiece contact surface form a precise fit, assisting in initial position calibration and providing a reference for subsequent milling. The guide plate provides lateral support through its contact surface with the workpiece, reducing lateral displacement and vibration during milling, ensuring uniform force on the milling cutter, and preventing ripples or burrs on the machined surface.

[0042] Pressure roller

[0043] The front pressure roller applies positive pressure to fix the strip before it enters the cutting edge, preventing deviation due to vibration or cutting force and ensuring milling stability. The pressure of the front pressure roller can be adjusted to provide suitable preload for strips of different thicknesses. The low-friction structure on the roller surface reduces sliding resistance with the strip, allowing the material to smoothly enter the machining area.

[0044] Bearing housing left and right fixing mechanism

[0045] When the milling cutter cuts, the material vibrates. The left and right fixing mechanisms of the bearing housing can reduce the amplitude in the horizontal direction. The fixing mechanism is powered by hydraulic oil, which has a fast response speed, convenient pressure adjustment, and smooth and reliable movement.

[0046] milling cutter

[0047] WC alloy ultrafine particles are pressed and sintered to form superhard alloy cutting tools with excellent cutting characteristics.

[0048] The matching of the milling cutter's rotational speed, feed per cut, and production line speed during milling is a key factor in cutting quality. 400–600 m / min is the range for medium to high speed milling. The feed rate is determined by the characteristics of the material being cut; a larger feed rate is used for softer materials, and a smaller feed rate is used for harder materials.

[0049] Accessibility

[0050] Cooling and lubrication

[0051] Before milling, the cutting fluid is atomized with air and sprayed under high pressure onto the front guide plate, carrying away the heat generated by friction between the workpiece and the guide plate, and also providing lubrication. During milling, the atomized cutting fluid is continuously sprayed onto the milling cutter, reducing the heat generated during milling.

[0052] Bearing lubrication

[0053] Milling cutter bearings generate a significant amount of heat during high-speed operation. If this heat cannot be dissipated effectively and promptly, it will severely impact bearing performance and lifespan. The forced lubrication system of the milling cutter bearings achieves efficient cooling, removing the heat generated during high-speed operation.

[0054] Chip removal system

[0055] The shavings collection hopper introduces copper shavings into the pipeline, and the fan generates negative pressure to draw the copper shavings and air at a certain flow rate into the vortex separator for collection, and then packages them off-line.

[0056] Side guide plate

[0057] After milling, the guide plate guides the material along a preset path, ensuring the processed blank stably leaves the milling area and preventing deviation due to inertia or residual stress. Several nozzles are distributed on the guide plate to provide cooling circulation for the tool and material. As a physical barrier, the guide plate intercepts milling debris, preventing it from entering the transmission system or affecting the operation of subsequent equipment.

[0058] Exiting side pressure roller

[0059] The pressing force of the exit-side pressure roller can be adjusted by a pressure-reducing valve, and its simultaneous use with the inlet-side pressure roller ensures material stability during milling. After the strip separates from the milling cutter and back roller, material deviation is effectively prevented.

[0060] In summary, this application's technical solution, combining multi-dimensional innovation, solves the vibration control problem in copper strip milling, improves the surface machining accuracy of the strip, achieving a surface roughness Ra≤1.6, transverse thickness deviation≤0.03mm, and longitudinal thickness deviation≤0.1mm. The bearing housing temperature is controlled, the linear speed is increased to 20 / min, and efficiency is improved by more than double. Vibration and temperature are effectively controlled, and the milling cutter life is significantly extended. The cutting length of brass is extended to over 20,000m.
