Description

Technical Field

[0001] This utility model relates to the field of milling technology, and in particular to a milling machine device for adjustable milling of multi-specification plates. Background Technology

[0002] Electronic aluminum foil is the raw material for aluminum electrolytic capacitors. It is made from high-purity aluminum with a purity of ≥99.99%. The aluminum is remelted in a melting and holding furnace, a certain amount of trace elements are added, and then it is cast into ingots with a length, width and thickness of approximately 6500mm*1060mm*365~520mm. The ingots are then processed into electronic aluminum foil through milling, homogenization treatment, hot rolling, cold rolling, foil rolling and finished product annealing. The aluminum foil is then etched and formed, and then slit to make the anodes in aluminum electrolytic capacitors.

[0003] Before milling an ingot, the feed rate must be confirmed first. Then, the milling machine cutter head is manually adjusted to the milling position before milling begins. During milling, a certain thickness needs to be milled off one side of the ingot to remove crystal segregation, nodules, and other casting defects from the aluminum alloy ingot surface. However, milling machines are typically designed and installed to produce ingots of a certain thickness. Companies usually purchase milling machines of a certain size based on their own production needs. For example, if a milling machine with a maximum opening size of 450mm is purchased, and 25mm of tool setting allowance is reserved on each side, then the milling machine can only process ingots less than 400mm thick. However, there are often production needs for larger sizes. Milling machines occupy a lot of space, with the main unit alone being 15 meters long and 6-7 meters high. Adding the auxiliary parts, the footprint is more than doubled, and the purchase cost is also high. Therefore, how to make a single machine more versatile and capable of milling ingots of more specifications is a problem worth studying.

[0004] The above background information is provided only to aid in understanding the concept and technical solution of this utility model. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above information was disclosed on the filing date of this patent application, the above background information should not be used to evaluate the novelty and inventiveness of this application. Utility Model Content

[0005] The purpose of this utility model is to propose a milling machine device that can adjust the milling of multi-specification plates and ingots, so as to solve the technical problems of the existing milling machine, such as the limited maximum opening size of the cutter head and the inability to mill plates and ingots of limited thickness.

[0006] Therefore, this utility model proposes a milling machine device for adjustable milling of multi-specification plate ingots.

[0007] Preferably, the present invention may also have the following technical features:

[0008] A milling machine device for adjustable milling of multi-specification slabs includes a gantry frame, a left cutter head, a right cutter head, a cutter head cover, and a chip extraction cylinder;

[0009] The gantry frame includes two supports and two crossbeams. The supports are arranged in an inverted "V" shape with their open ends on the ground. The two crossbeams are respectively arranged on the two outer sides of the supports and close to the closed ends of the supports to connect the supports.

[0010] The left and right cutter discs are disc-shaped and are symmetrically arranged between the two supports and below the crossbeam. Each of them has several cutters on its end face, which can move left and right to mill the surface of the plate ingot.

[0011] Both the left and right cutter discs are provided with cutter disc covers on the same side, which can move forward and backward with them. The cutter disc covers are hollow structures and include a first cover, a second cover, and a third cover. The first cover is arc-shaped, with its lower half covering the left and right cutter discs and its upper half vertically upward. The third cover is located above the first cover, with its upper end face higher than the upper surface of the crossbeam and its lower end face protruding from the lower surface of the crossbeam. The second cover is detachably installed between the first and third covers via a flange. It is available in various specifications to adjust the maximum opening distance of the left and right cutter discs, so as to accommodate ingots of different thicknesses. This allows the same milling machine to produce ingots of multiple specifications. According to production needs, a second cover of a certain specification is installed between the first and third covers.

[0012] The chip extraction cylinder is connected to the cutter head cover and can move with the cutter head cover. It is located on the upper surface of the third cover and is used to automatically collect the chips generated during the milling process.

[0013] Preferably, it also includes a worktable, the upper end of which is used to place the plate ingot to be milled, and the lower end is provided with a moving device to feed the plate ingot into and out between the left cutter head and the right cutter head.

[0014] Preferably, a sliding baffle is provided between the third protective cover and the chip extraction cylinder.

[0015] Preferably, the first, second, and third protective covers are all welded with flanges, and several through holes are provided on the flanges, which are fixed by bolts and nuts.

[0016] Preferably, the flange is made of stainless steel.

[0017] Preferably, the second protective cover is a vertical structure and is installed vertically with the first and third protective covers.

[0018] Preferably, the second protective cover is tilted, with its lower end tilted outwards, which increases the maximum opening of the left cutter head and the right cutter head.

[0019] Preferably, the cutting tools include roughing cutters and finishing cutters, which are distributed in a stepped manner around the left cutter head and the right cutter head.

[0020] Preferably, the system further includes a chip suction system connected to the chip extraction cylinder, so that the chips generated during the milling process can pass through the cutter head cover and enter the chip suction system through the chip extraction cylinder.

[0021] The beneficial effects of this utility model compared with the prior art include:

[0022] 1. The adjustable milling machine device for multi-specification slabs of this utility model divides the cutter head cover connected to the chip extraction cylinder into a first cover, a second cover, and a third cover, and uses a flange connection to allow the second cover to be disassembled. The second cover can be set to multiple specifications, and the corresponding specification of the second cover can be installed according to different production needs to adjust the maximum distance that the left cutter head and the right cutter head can open, so as to accommodate slabs of different thicknesses. This allows the same milling machine to produce slabs of multiple specifications, making the device more applicable, reducing the production cost of enterprises, and improving economic efficiency.

[0023] 2. This device, by setting up a chip extraction cylinder and a chip suction system, can automatically collect the chips generated during the milling process, reduce manual cleaning, lower the production risk factor, save labor costs, improve productivity, and make the overall environment clean and environmentally friendly.

[0024] 3. The device sets the second guard in an inclined state, with its lower end tilted outward, which increases the maximum opening of the left and right cutter heads, enabling the device to mill larger slabs.

[0025] 4. This device improves milling efficiency by setting up a left and right cutter head for double-sided milling. Both the left and right cutter heads are equipped with roughing cutters and finishing cutters, which are distributed in a stepped manner around them to increase the amount of milling done in one pass and improve milling accuracy.

Detailed Implementation

[0031] The present invention will now be described in further detail with reference to specific embodiments and the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope and application of the present invention.

[0032] Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein the same reference numerals denote the same parts unless otherwise specifically stated.

[0033] A milling machine device for adjustable milling of multi-specification plates, such as Figures 1-4As shown, the structure includes a gantry frame 1, a left cutter head 2, a right cutter head 3, a cutter head cover 5, and a chip extraction cylinder 6. The gantry frame 1 includes two supports 11 and two crossbeams 12. The supports 11 are arranged in an inverted "V" shape at intervals, with their open ends placed on the ground. This structure of the gantry frame 1 is more stable. The two crossbeams 12 are respectively arranged on the two outer sides of the supports 11 and close to the closed ends of the supports 11 to connect them. The left cutter head 2 and the right cutter head 3 are disc-shaped and symmetrically arranged between the two supports 11 and below the crossbeams 12. Each of their end faces is provided with several cutters 4, which can move left and right to mill the surface of the ingot. It can be understood that the left cutter head 2 and the right cutter head 3 are respectively connected to a drive device to drive their movement. Specifically, the drive device may include a gear structure and a motor, which together drive the left cutter head 2 and the right cutter head 3 to move forward and backward. Both the left cutter head 2 and the right cutter head 3 are provided with a cutter head cover 5 on the same side, which can move forward and backward with them. The cutter head cover 5 is a hollow structure, which includes a first cover 51, a second cover 52 and a third cover 53. The first cover 51 is arc-shaped, with its lower half covering the left cutter head 2 and the right cutter head 3, and its upper half vertically upward. The lower half can partially cover the left cutter head 2 and the right cutter head 3, and there is a gap between it and the left cutter head 2 and the right cutter head 3 to better collect the material chips generated during the milling process. The third protective cover 53 is positioned above the first protective cover 51, with its upper end face higher than the upper surface of the crossbeam 12 and its lower end face protruding from the lower surface of the crossbeam 12. The second protective cover 52 is detachably mounted between the first protective cover 51 and the third protective cover 53 via a flange 54. It comes in various specifications to adjust the maximum opening distance between the left cutter head 2 and the right cutter head 3, allowing for the placement of ingots of different thicknesses. This enables the same milling machine to produce ingots of multiple specifications. According to production needs, a specific specification of the second protective cover 52 can be installed between the first protective cover 51 and the third protective cover 53, making the device more widely applicable, reducing the cost of purchasing production equipment for enterprises, and improving their economic efficiency. The chip extraction cylinder 6 is connected to the cutter head cover 5 and can move with the cutter head cover 5. It is positioned on the upper end face of the third protective cover 53 and is used to automatically collect the chips generated during the milling process, reducing manual cleaning, lowering the production risk factor, saving labor costs, improving productivity, and making the overall environment clean and environmentally friendly.

[0034] Specifically, such as Figure 2As shown, it also includes a worktable 7, the upper end of which is used to place the plate ingot to be milled (not shown in the figure), and the lower end is provided with a moving device (not shown in the figure) to send the plate ingot into and out between the left cutter head 2 and the right cutter head 3. It can be understood that before milling, the worktable is not between the cutter heads. A guide rail or other device that can move it can be provided on the lower end of the worktable 3. After the plate ingot is placed on the worktable 7, it is moved into the space between the cutter heads and clamped by a clamping mechanism. Specifically, the clamping mechanism can be set on the gantry frame 1 to clamp both ends of the plate ingot.

[0035] Specifically, such as Figure 1 A sliding baffle 8 is provided between the third protective cover 53 and the chip extraction cylinder 6, and may also include a chip suction system (not shown in the figure). The chip suction system is connected to the chip extraction cylinder 6, so that the chips generated during the milling process can pass through the cutter head cover and enter the chip suction system through the chip extraction cylinder, so that the chip washing system can work better and improve its chip suction effect.

[0036] Specifically, flanges 54 are welded onto the first protective cover 51, the second protective cover 52, and the third protective cover 53. Several through holes are provided on the flanges 54, which are fixed using bolts and nuts. To improve the service life of the second protective cover 52, the flanges can be made of stainless steel. When it is necessary to replace the second protective cover 52 with another specification, simply loosen the bolts, replace it with a different second protective cover 52, and fix it with bolts again. This structure is simple, easy to disassemble and maintain, and also makes the milling machine device more widely applicable. Specifically, as... Figure 3 As shown, the second protective cover 52 can be a vertical structure, that is, it is installed vertically with the first protective cover 51 and the third protective cover 53, as shown. Figure 4 As shown, the second protective cover 52 can also be configured in an inclined state, with its lower end tilted outwards. For example... Figure 1As shown, the second guard 52 is located below the crossbeam 12, so setting the second guard 52 in an inclined state does not affect the overall movement of the cutter head guard 5. That is to say, when the third guard 53 reaches the limit (close to the crossbeam 12), setting the second guard 52 in an inclined state can increase the maximum opening distance of the left cutter head 2 and the right cutter head 3 to a certain extent. It is understandable that the second guard 52 cannot be tilted indefinitely. It can be set in an inclined state according to the needs and the actual site conditions, with an angle of 75° to 89° with the flange 54. The specific angle is not limited. This makes the maximum opening of the left cutter head 2 and the right cutter head 3 larger, which can accommodate thicker ingots, making the device more versatile. For example, when a company needs to produce slabs with a thickness of 390mm, with the addition of a 25mm tool setting allowance for each of the left and right cutter heads 2 and 3, the distance between the cutter heads needs to be at least 440mm (390+25+25=440). When the second guard 52 of this milling machine is a vertical structure, the maximum distance the cutter heads can open is 450mm, which is greater than 440mm. In this case, the vertical structure of the second guard 52 is sufficient. When a company needs to produce slabs with a thickness of 500mm, with the addition of a 25mm tool setting allowance for each of the left and right cutter heads 2 and 3, the cutter heads need to be able to open at least 550mm (500+25+25=550). In this case, the inclined structure of the second guard 52 needs to be selected so that the maximum opening size of the left and right cutter heads 2 and 3 is greater than 550mm, so that the 500mm slab can be milled.

[0037] Specifically, the cutting tool 4 includes a roughing cutter and a finishing cutter, which are distributed in a stepped manner around the left cutter head 2 and the right cutter head 3. With one loading, double-sided milling can be performed simultaneously, improving milling efficiency. Setting the roughing cutter and the finishing cutter and distributing them in a stepped manner around them increases the amount of milling done in one pass and improves milling accuracy.

[0038] The above-mentioned device is used as follows: Select the second protective cover 52 with the corresponding structure according to production needs, install the second protective cover 52 together with the first protective cover 51 and the third protective cover 53, place the plate ingot on the worktable 7, move the worktable 7 between the left cutter head 2 and the right cutter head 3, clamp the plate ingot, manually adjust the reference positioning (the same thickness of material only needs to be adjusted once), start milling, after milling is completed, release the clamping mechanism, move out of the worktable 7, and unload the material to complete the entire milling work.

[0039] Those skilled in the art will recognize that numerous variations are possible with respect to the above description, and the embodiments and figures are merely for describing one or more specific implementations.

[0040] Although exemplary embodiments of the present invention have been described and illustrated, those skilled in the art will understand that various changes and substitutions can be made thereto without departing from the spirit of the present invention. Furthermore, many modifications can be made to adapt specific situations to the doctrine of the present invention without departing from the central concept of the present invention described herein. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but may include all embodiments and equivalents that fall within the scope of the present invention.
