Description

Technical Field

[0001] The present application belongs to the technical field of copper material processing, and in particular relates to a device for copper strip correction and burr removal. Background Art

[0002] In the process of removing burrs, the pressing force of the roller of the traditional deburring machine is concentrated on the edge of the copper belt, which is easy to affect the flatness of the copper belt surface. Moreover, if the debris is not cleaned up in time after the burr treatment is completed, the burrs will be retained, and the debris attached to the surface of the copper belt will be pressed back into the copper belt by other rollers, causing scratches on the copper belt. Summary of the invention

[0003] The present application provides a device for copper strip correction and burr removal, which can clean up in time after the burr is removed and maintain the original thickness of the copper strip.

[0004] The technical solution of the present application is as follows: A device for copper strip correction and burr removal comprises a frame having a processing space for copper strip processing and a processing inlet and a processing outlet for entering and exiting the processing space; A plurality of lower polishing rollers and their matching lower polishing roller shaft seats are arranged at the bottom of the processing space, and upper polishing rollers and their matching upper polishing roller shaft seats are arranged between adjacent lower polishing rollers; A lifting device is provided at the top of the processing space, and the lifting device is connected to the polishing roller through an upper roller box plate, and the lifting device is used to drive the upper polishing roller shaft seat to rise and fall so that the upper polishing roller has a first position simultaneously tangent to the adjacent lower polishing roller and a second position simultaneously separated from the upper polishing roller; The upper roller box plate is also provided with a vacuum scrap suction device, which has a suction port and faces the tangent surface between the upper polishing roller and the lower polishing roller when the upper polishing roller is in the first position.

[0005] Furthermore, the lifting device includes a lead screw connected to the polishing roller shaft seat and a turbine and a worm that drive the lead screw.

[0006] Furthermore, the lifting device is fixed to the frame via a saddle.

[0007] Furthermore, there are several suction ports, each of which faces a tangent point.

[0008] Furthermore, the frame is provided with an extension frame in front of the processing inlet and behind the processing outlet, the extension frame is provided with a feed inlet and a discharge port flush with the processing inlet and the processing outlet, and an air blowing device is provided above the feed inlet and the discharge port facing the processing inlet and the processing outlet respectively.

[0009] Furthermore, a lower roller box plate for fixing the lower smooth roller shaft seat and the lower smooth roller is provided at the bottom of the processing space.

[0010] Due to the adoption of the above technical solution, the beneficial effects of this application are as follows: 1. The present application designs the structure of upper and lower polished rollers, which cooperate with the processing outlet and processing entrance to realize the correction of the copper strip. Specifically, the upper polished roller provides downward pressure, and the lower polished roller provides support force. After the copper strip enters the processing space, the upper and lower polished rollers are limited at different positions to achieve shape correction, so that the thickness of the copper strip is uniform. In other words, the present application uses staggered rolling to correct the shape. Different from the relative rolling method, staggered rolling can effectively prevent the copper strip from getting stuck. The copper strip passes through the lower polished roller and the upper polished roller in turn, and the correction can be repeated multiple times of upper and lower rolling, thereby reducing the thickness difference between each position.

[0011] 2. In the present application, all the polishing rollers are connected to a lifting device to ensure that there is no height difference between the polishing rollers, which helps to improve the accuracy of correction.

[0012] 3. In the present application, the upper polishing roller is tangent to the adjacent lower polishing roller after it descends, in order to ensure that the lowest point of the upper polishing roller is located between the two lower polishing rollers during rolling. Because during staggered rolling, if the lowest point of the upper polishing roller deviates from the middle, the copper strip will have different torques on both sides after passing the lowest point of the deviated upper polishing roller, which will cause the copper strip to bend, which is not conducive to the correction of the copper strip. The present application improves this disadvantage by accurately positioning the upper and lower polishing rollers.

[0013] 4. The present application can timely and efficiently suck away the debris generated by burrs. The present application places the suction port at a position facing the tangent point, which is also the point closest to the burr generation position when processing the copper strip. No matter where the burr falls, it will be pushed into the edge of the smooth roller as the copper strip moves forward, so that it can be efficiently sucked in by the suction port.

DETAILED DESCRIPTION

[0016] Based on the background technology, the present application provides a device for copper strip correction and burr removal, including a frame 1, the frame 1 having a processing space 2 for copper strip processing and a processing entrance 3 and a processing exit 4 for entering and exiting the processing space 2; a plurality of lower polishing rollers 5 and their corresponding lower polishing roller 5 shaft seats are provided at the bottom of the processing space 2, and an upper polishing roller 7 and its corresponding upper polishing roller 7 shaft seat are provided between adjacent lower polishing rollers 5; a lifting device 9 is provided at the top of the processing space 2, the lifting device 9 is connected to the upper polishing roller 7 through an upper roller box plate 13, the lifting device 9 is used to drive the upper polishing roller 7 shaft seat to rise and fall so that the upper polishing roller 7 has a first position that is simultaneously tangent to the adjacent lower polishing roller 5 and a second position that is simultaneously separated from the upper polishing roller 7; the upper roller box plate 13 is also provided with a vacuum chip suction device 10, the vacuum chip suction device 10 has a suction port 10-1 and the suction port 10-1 faces the tangent surface of the upper polishing roller 7 and the lower polishing roller 5 when the upper polishing roller 7 is in the first position.

[0017] After the upper polishing roller 7 descends, it is tangent to the adjacent lower polishing roller 5 at the same time, so as to ensure that the lowest point of the upper polishing roller 7 is located between the two lower polishing rollers 5 during rolling. Because during staggered rolling, if the lowest point of the upper polishing roller 7 deviates from the middle, the copper strip will have different moments on both sides after passing the lowest point of the deviated upper polishing roller 7, which will cause the copper strip to bend, which is not conducive to the correction of the copper strip. The present application improves this disadvantage by accurately positioning the upper and lower polishing rollers 5 relative to each other.

[0018] In the present application, the frame 1 is fixedly placed, and the copper strip is fed into the processing entrance 3 by a conveyor belt. As an example but not a limitation, the width of the upper polishing roller 7 and the lower polishing roller 5 in the present application should be greater than the width of the copper strip, that is, the rolling is performed on the entire cross section of the copper strip, which can improve the efficiency of burr removal on the one hand, and reduce the probability of uneven surface of the copper strip due to uneven force on the copper strip on the other hand.

[0019] As a preferred embodiment of the present application, the lifting device 9 includes a lead screw connected to the shaft seat of the polishing roller 7 and a worm gear and a gear for driving the lead screw. The lead screw and the worm gear drive the upper and lower parts of the mature existing Technology, at the same time, the worm gear structure also has a self-locking function, which can be limited at the required height. The lifting device 9 drives the shaft seat of the polishing roller 7 and the polishing roller 7 to move through the lead screw, so as to adjust the distance between the upper and lower polishing rollers 5 according to the thickness of the copper strip.

[0020] In a specific implementation of the above embodiment, the lifting device 9 is fixed to the frame 1 via a saddle 11 .

[0021] As a preferred embodiment of the present application, the number of the suction ports 10-1 is several and they are respectively directed toward each tangent point. Figure 1 and attached Figure 2 As shown, there are three lower polishing rollers 5 and two upper polishing rollers 7. There are four tangent points on both sides of the upper polishing rollers 7 and between the two upper polishing rollers 7. Therefore, there are four suction ports 10-1, which are respectively oriented to each tangent point. Because in the actual processing process, the copper strip moves forward, and the burrs may be blocked from moving backward after falling off, or they may fall on the copper strip moving forward. Therefore, setting the vacuum suction ports 10-1 in all directions in the front and back can improve the suction efficiency of the burrs.

[0022] As a preferred embodiment of the present application, the frame 1 is provided with an extension frame 12 in front of the processing entrance 3 and behind the processing exit 4, and the extension frame 12 is provided with a feed port and a discharge port flush with the processing entrance 3 and the processing exit 4, and an air blowing device facing the processing entrance 3 and the processing exit 4 is provided above the feed port and the discharge port. The extension frame 12 is arranged on both sides before and after the copper strip is processed, that is, a purge is performed before the copper strip enters the processing space 2 and after it leaves the processing space 2. The pre-processing purge is to remove dust, debris, etc., and the crushed copper strip is placed. The post-processing purge is a supplementary measure to improve the cleaning efficiency. In the present application, the extension frame 12 formed below can be regarded as the processing entrance 3 and the processing exit 4. The air blowing device can be realized based on the existing technology, and it is arranged above the processing entrance 3 and the processing exit 4.

[0023] As a preferred embodiment of the present application, a lower roller box plate 14 for fixing the shaft seat of the lower polishing roller 5 and the lower polishing roller 5 is provided at the bottom of the processing space 2 .

[0024] The upper roller box plate 13 is used to fix the upper roller seat, the polishing roller 7 and the vacuum scrap suction device 10, and transmit the lifting and pressing torque of the lifting device 9. The lower roller box plate 14 is used to fix the lower roller seat to the frame 1.

The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
