Description

Technical Field

[0001] This utility model relates to the field of aluminum processing technology, specifically to a cold-forming aluminum processing uncoiling device. Background Technology

[0002] Cold forming is a processing method that involves punching, shearing, bending, stretching, etc., without heating. Cold forming is neither a one-time forming nor a two-time forming, but a new and promising processing technology. Aluminum and aluminum alloys are among the most widely used and economical materials. Uncoiling equipment is a component of aluminum processing production lines, mainly used to gradually unwind coiled aluminum strips to provide a continuous and stable material supply for subsequent stamping, forming, cutting, and other processes.

[0003] Chinese patent provides a cold-forming aluminum processing uncoiling device, publication number CN213037080U, which includes a substrate. The upper surface of the substrate is provided with a support plate one and a support plate two. The support plate one is fixedly connected to a fixing plate by an electric push rod. The fixing plate is installed on the upper surface of the substrate.

[0004] The above-mentioned device sets up an extrusion plate one and an extrusion plate two, and uses a motor two to drive the screw to rotate, so that the movable plate drives the extrusion plate two to move up or down through the slide bar. In this way, the distance between the extrusion plate one and the extrusion plate two can be adjusted according to the thickness of the aluminum strip, and the aluminum strip can be extruded and flattened, effectively ensuring the flatness of the aluminum strip after unwinding, and the guide rollers effectively reduce friction.

[0005] However, its structure is relatively simple and lacks a step to clean the unfolded aluminum coil. Impurities are easily adhered to the top surface of the aluminum strip. When cold stamping is performed directly, the friction is large, which affects the service life of the mold and makes it difficult to lubricate. The aluminum strip and the die wall are dry-frictioned for a long time, which can easily leave scratches parallel to the drawing direction and affect the processing quality. Utility Model Content

[0006] The purpose of this invention is to provide a cold-forming aluminum processing uncoiling device, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A cold-forming aluminum processing uncoiling device includes an uncoiling frame, a support plate is fixedly installed at one side of the front end of the uncoiling frame, and an air expansion shaft is installed on the inner side of the support plate via a rotating shaft. An aluminum coil body is provided on the outer ring of the air expansion shaft. A guide roller is installed at the upper part of the inside of the uncoiling frame via a mounting bracket. An electric telescopic rod is installed at the front of the top of the uncoiling frame.

[0009] The push rod end of the second electric telescopic rod is connected to a connecting plate via connecting bolts. A sponge wiping block is provided at the bottom of the connecting plate. Mounting bolt posts are provided on both sides of the top of the sponge wiping block. The outer ring of the mounting bolt posts is threaded with mounting nuts. The sponge wiping block is installed at the bottom of the connecting plate via the mounting bolt posts and mounting nuts. The push rod of the second electric telescopic rod extends and retracts to drive the sponge wiping block to rise and fall. Inside the unwinding frame and below the guide roller, an electric telescopic rod is installed. A leveling roller is installed at the top of the push rod of the first electric telescopic rod. One end of the aluminum coil body extends into the unwinding frame, and the extended part is in the shape of an unfolded aluminum strip. The aluminum strip passes between the guide roller and the leveling roller. The guide roller and the leveling roller cooperate to level the aluminum strip.

[0010] Preferably, the sponge wiping block is detachably installed at the bottom end of the connecting plate by means of a mounting nut and a mounting bolt, and the bottom surface of the sponge wiping block is in contact with the top surface of the unfolded aluminum roll body.

[0011] Preferably, a wool felt coating roller is rotatably mounted at the center of the unwinding frame via a rotating rod. A liquid delivery pipe is provided through the top of the unwinding frame, and one end of the liquid delivery pipe extending into the unwinding frame is connected to a spray pipe. A drain solenoid valve is provided at the connection between the spray pipe and the liquid delivery pipe. The spray pipe and the wool felt coating roller are on the same vertical line, and the auxiliary liquid is delivered to the top of the wool felt coating roller and dripped out through the spray pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model, by setting up a sponge wiping block and an electric telescopic rod in conjunction with the aluminum coil body, allows for the wiping of impurities on the top surface of the aluminum coil body by continuously pressing the sponge wiping block against the top surface of the aluminum strip after the aluminum coil body is leveled by the leveling roller and the electric telescopic rod. This reduces the friction generated during cold stamping, thereby reducing the impact on the mold life. Furthermore, the sponge wiping block is installed at the connecting plate by mounting bolts and mounting nuts, making it easy for personnel to disassemble and replace after the service life is reached.

[0017] By setting up a wool felt coating roller, a cleaning motor, a liquid delivery pipe, and a spray pipe to work together, a layer of stamping-assisted liquid film can be applied to the top surface of the aluminum strip after dust removal. The cold stamping process is a non-dry friction process, which reduces damage to the cutting edge of the mold and reduces the probability of scratches, thus improving the yield of finished products.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Combination Figures 1-4A cold-forming aluminum processing uncoiling device includes an uncoiling frame 1. A support plate is fixedly installed on one side of the front end of the uncoiling frame 1, and an air expansion shaft 2 is installed on the inner side of the support plate via a rotating shaft. An aluminum coil body 3 is provided on the outer ring of the air expansion shaft 2. A guide roller 4 is installed on the upper part of the inside of the uncoiling frame 1 via a mounting frame. An electric telescopic rod 7 is installed on the front part of the top of the uncoiling frame 1.

[0026] See Figure 2 and Figure 3 Furthermore, an electric telescopic rod 5 is installed inside the unwinding frame 1 and below the guide roller 4. A leveling roller 6 is installed at the top of the push rod of the electric telescopic rod 5. One end of the aluminum coil body 3 extends into the unwinding frame 1, and the extended part is in the shape of an unfolded aluminum strip. The aluminum strip passes between the guide roller 4 and the leveling roller 6. The guide roller 4 and the leveling roller 6 cooperate to level the aluminum strip. A wool felt coating roller 14 is installed in the center of the unwinding frame 1 via a rotating rod. A liquid delivery pipe 13 is installed through the top of the unwinding frame 1. One end of the liquid delivery pipe 13 that extends into the unwinding frame 1 is connected to a spray pipe 12. A drain solenoid valve is installed at the connection between the spray pipe 12 and the liquid delivery pipe 13. The spray pipe 12 and the wool felt coating roller 14 are on the same vertical line. The auxiliary liquid is delivered to the top of the wool felt coating roller 14 and dripped out through the spray pipe 12. A coating motor is set in the center of one side of the unwinding frame 1. The drive shaft of the coating motor is connected to the rotating rod of the wool felt coating roller 14 through a plum blossom coupling. An unwinding motor is installed on one side of the support plate. The end of the drive shaft of the unwinding motor is connected to the rotating shaft of the air expansion shaft 2 through a coupling. A guide support roller 16 is rotatably installed inside the unwinding frame 1 and below the aluminum strip. A waste collection box 15 is set inside the unwinding frame 1 and below the wool felt coating roller 14. The waste collection box 15 is used to collect the dripping waste liquid or waste.

[0027] Specifically, by controlling the extension of the push rod of the electric telescopic rod 5, the leveling roller 6 can be driven to rise to level the unfolded aluminum strip. The guide support roller 16 can lift the aluminum strip to prevent it from sagging. The aluminum strip passes through the unwinding frame 1, and its top surface contacts the outer ring of the wool felt coating roller 14. At this time, the external stamping auxiliary liquid delivery pipe and the liquid delivery pipe 13 can be connected in advance according to the processing needs. Subsequently, the drain solenoid valves set at the liquid delivery pipe 13 and the spray pipe 12 can be opened to deliver the stamping auxiliary liquid to the spray pipe 12 for spraying, thereby wetting the wool felt coating roller 14. Then, the coating motor can be started to drive the wool felt coating roller 14 to rotate continuously so as to apply the auxiliary liquid to the top surface of the aluminum strip. This makes the subsequent cold stamping process non-dry friction processing, reduces the damage to the die cutting edge, reduces the probability of scratches on the finished product surface, and improves the processing yield.

[0028] Example 2

[0029] See Figure 3 and Figure 4 Furthermore, based on Embodiment 1, the push rod end of the electric telescopic rod 2 7 is further provided with a connecting plate 8 installed by connecting bolts. A sponge wiping block 9 is provided at the bottom end of the connecting plate 8. Mounting bolt posts 10 are provided at the top of the sponge wiping block 9 near both sides. The outer ring of the mounting bolt posts 10 is threaded with mounting nuts 11. The sponge wiping block 9 is installed at the bottom end of the connecting plate 8 by the mounting bolt posts 10 and mounting nuts 11. The electric telescopic rod 2 7 push rod extends and retracts to drive the sponge wiping block 9 to rise and fall. The sponge wiping block 9 is detachably installed at the bottom end of the connecting plate 8 by the mounting nuts 11 and mounting bolt posts 10. The bottom surface of the sponge wiping block 9 is in contact with the top surface of the unfolded aluminum coil body 3. An electrical control box 17 is provided at the rear side of the unwinding frame 1. The electrical control box 17 is electrically connected to the electric telescopic rod 1 5, the electric telescopic rod 2 7, the liquid draining solenoid valve, the unwinding motor, and the coating motor.

[0030] Specifically, since the sponge wiping block 9 is installed at the end of the push rod of the electric telescopic rod 7 through various components, the sponge wiping block 9 can be pushed down by controlling the extension of the push rod of the electric telescopic rod 7. This allows the bottom surface of the sponge wiping block 9 to be in contact with the top surface of the aluminum strip, so as to continuously wipe the passing aluminum strip. This can effectively remove residual dust and other impurities on the aluminum strip, thereby avoiding the generation of large friction due to a large number of impurities during subsequent processing. After the sponge wiping block 9 reaches the preset service life, the operator can unscrew the mounting nut 11 as needed, and then remove the sponge wiping block 9 from the bottom surface of the connecting plate 8 for replacement.

[0031] In actual operation, the steps of replacing and unwinding the aluminum coil body 3 in the existing technology will not be described here. By controlling the extension of the push rod of the electric telescopic rod 5, the leveling roller 6 can be driven to rise so as to level the unfolded aluminum strip. The aluminum strip can be lifted by the set guide support roller 16 to prevent it from falling. The aluminum strip passes through the unwinding frame 1 and its top surface contacts the outer ring of the wool felt coating roller 14. At this time, the external stamping auxiliary liquid delivery pipe and the liquid delivery pipe 13 can be connected in advance according to the processing needs. Then, the liquid discharge solenoid valve set at the liquid delivery pipe 13 and the spray pipe 12 can be opened so as to deliver the stamping auxiliary liquid to the spray pipe 12 and spray it out, thereby wetting the wool felt coating roller 14. Then, the coating motor can be started to drive the wool felt coating roller 14 to rotate continuously so as to apply the auxiliary liquid to the top surface of the aluminum strip, so that the subsequent cold stamping process is non-dry friction processing, reducing the damage to the die edge, reducing the probability of scratches on the surface of the finished product, and improving the processing yield.

[0032] Because the sponge wiping block 9 is installed at the end of the push rod of the electric telescopic rod 7 through various components, the sponge wiping block 9 can be pushed down by controlling the extension of the push rod of the electric telescopic rod 7. This allows the bottom surface of the sponge wiping block 9 to be in contact with the top surface of the aluminum strip, so as to continuously wipe the aluminum strip. This can effectively remove residual dust and other impurities on the aluminum strip, thereby avoiding the generation of large friction due to a large number of impurities during subsequent processing. After the sponge wiping block 9 reaches the preset service life, the operator can unscrew the mounting nut 11 as needed, and then the sponge wiping block 9 can be removed from the bottom surface of the connecting plate 8 for replacement.

[0033] Furthermore, the external liquid pipe of the infusion pipe 13 can be adjusted according to the processing conditions. It can use graphite suspension, water-based cutting fluid, or deionized water as auxiliary liquid according to the working conditions. When the aluminum strip thickness is <0.08mm or the drawing depth is >40%, special volatile oil for aluminum strip processing can be used. At the same time, the material of the coating roller can be adjusted adaptively. It is not limited to one or two usage conditions. Therefore, it will not be elaborated in detail. The technical solution described in this embodiment shall prevail.

[0034] Furthermore, the display and control components and modules used in the aforementioned electric telescopic rod 7, electric telescopic rod 5, solenoid valve, unwinding motor, coating motor, and drain solenoid valve are all existing technologies, which can be fully implemented by those skilled in the art. The power supply is also common knowledge in the field and does not need to be elaborated. The content protected by this utility model does not involve the improvement of software and methods. Moreover, this utility model is mainly used to protect mechanical mechanisms, so the control method and circuit connection will not be explained in detail in this utility model.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
