Description

Technical Field

[0001] This invention relates to the field of aluminum sheet and strip processing technology, specifically to an integrated device and method for high-precision slitting and deburring of aluminum sheets and strips. Background Technology

[0002] After aluminum sheets and strips are rolled into shape, they need to be longitudinally slit into multiple narrow strips according to production specifications to meet the needs of subsequent stamping, bending, and deep processing. During the high-speed slitting process, metal burrs are very likely to be generated at the cut points. If not dealt with in time, they will seriously affect the subsequent assembly accuracy, product flatness, and safety in use.

[0003] Currently, most traditional processing techniques employ a split-processing model of "slitting first, then deburring." This involves first slitting the aluminum strips using a slitting machine, and then transferring them to a separate grinding machine for side deburring. This process is fragmented and cumbersome. Furthermore, most conventional deburring equipment can only perform planar grinding on aluminum strips of a single specification, making it unsuitable for multi-channel simultaneous processing. In traditional processes, multiple aluminum strips after slitting tend to stick together and interfere with each other, making simultaneous edge deburring impossible. Each strip must be processed sequentially, resulting in a cumbersome processing procedure and extremely low grinding efficiency.

[0004] It is evident that existing technologies lack an integrated continuous processing equipment and method that can achieve multi-channel synchronous slitting, automatic layer guidance, flattening and straightening, and precise deburring on both sides. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated device and method for high-precision slitting and deburring of aluminum strips. This device and method realizes multi-channel synchronous slitting and independent layered guidance, so that the slitting aluminum strips are at different height levels, which facilitates the setting of grinding units on both sides and the simultaneous grinding and deburring of both sides of multiple slitting aluminum strips, thereby improving work efficiency.

[0006] To achieve the above objectives, the present invention provides an integrated high-precision slitting and deburring device for aluminum sheet and strip. This device includes a slitting table with multiple cutting grooves dividing it into multiple flat platforms. A descending guide platform, a pressing platform, and a grinding platform are sequentially arranged at the rear end of each flat platform. The pressing platform and grinding platform connected to the same descending guide platform are at the same height, and a height difference exists between adjacent pressing platforms. A pressing roller assembly is provided on the pressing platform. Grinding machine units are installed on both sides of the grinding platform. A cutting machine unit is installed on the slitting table, and pressing mechanisms are provided on both sides of the cutting machine unit.

[0007] Preferably, the cutting unit includes a first gantry frame, on which a first movable frame driven by a first cylinder is slidably disposed, and a cutting machine is mounted on the lower end of the first movable frame, wherein the cutting blade mounted on the cutting machine is correspondingly disposed to the cutting groove.

[0008] Preferably, the pressing mechanism includes a second gantry frame, on which a second movable frame driven by a second cylinder is slidably disposed, and a cutting pressure roller is installed at the lower end of the second movable frame.

[0009] Preferably, the flattening roller assembly includes side plates installed on both sides of the pressing platform, and a height-adjustable flattening roller is installed between the two side plates.

[0010] Preferably, a guide shell is provided on the downward guide platform, and a smooth guiding gap is formed between the guide shell and the downward guide platform.

[0011] Preferably, a partition is provided between two adjacent downward guide platforms; side guards are provided on both sides of the cutting platform, and multiple support columns are provided at the bottom.

[0012] Preferably, the width of the polishing table is smaller than the width of the pressing platform, and recesses are formed on both sides.

[0013] Preferably, the grinding unit includes a mounting frame and grinding motors mounted at both ends of the mounting frame, with grinding wheels mounted on the grinding motors.

[0014] Preferably, the grinding wheel has a V-shaped grinding groove on its side.

[0015] This invention also provides a high-precision deburring method for aluminum sheet and strip, using the aforementioned integrated device, comprising the following steps: S1. Place the aluminum strip that needs to be slit and deburred on the slit table and push it forward. The aluminum strip is rolled and pressed by the set pressing mechanism. S2, the aluminum sheet and strip are cut by the cutting unit, so that each cut aluminum sheet and strip enters the corresponding downward guide table, pressing platform and grinding table in sequence; S3 guides each slit aluminum strip in layers via a downward guide table, flattens the bent aluminum strip by a flattening roller group, and grinds the burrs on both sides of the aluminum strip by a grinding machine group.

[0016] According to the above technical solution, the integrated device and method for high-precision slitting and deburring of aluminum sheet and strip provided by the present invention has the following beneficial effects: 1. By setting up a height difference structure between adjacent pressing platforms, and cooperating with the downward guide table and partition for isolation and guidance, multiple aluminum strips after slitting can be transported in layers with staggered positioning and independent isolation. This solves the problem of traditional equipment where multiple aluminum strips run in parallel and interfere with each other, making it impossible to perform edge deburring and grinding simultaneously. Each aluminum strip operates independently without interference, and can simultaneously complete flattening, straightening, and bilateral grinding operations, truly realizing multi-channel synchronous integrated processing. This significantly improves the overall processing efficiency of aluminum strip slitting and deburring, while effectively ensuring the consistency of slitting dimensions and grinding quality in each channel. 2. The machine integrates pressing and leveling, multi-blade cutting, layering guidance, roller pressing and leveling, and double-sided deburring functions on the same machine, realizing continuous and uninterrupted operation of feeding, cutting, leveling and deburring without the need for secondary clamping and transfer, which greatly shortens the processing steps and improves the overall production efficiency. 3. The cutting unit is equipped with pressing mechanisms on both sides, which roll and press the aluminum strip in advance through the cutting pressure rollers to ensure that the strip is flat and free of warping during the cutting process; together with the cylinder-driven lifting cutting machine and the precise alignment of the cutting groove, stable and high-precision longitudinal cutting is achieved. 4. Each channel is independently equipped with height-adjustable flattening roller groups to roll flatten the aluminum strip that is bent or arched after passing through the downward guide table after slitting, ensuring that the strip entering the grinding station is completely flat, providing a flat benchmark for subsequent high-precision deburring. 5. The machine adopts a symmetrical grinding unit on both sides, with a grinding wheel with a V-shaped grinding groove, which can accurately cover the cut edges of aluminum strips and remove burrs, sharp edges, and flared edges in a targeted manner, and is suitable for the grinding needs of the rounded transition of aluminum strip edges and corners. Compared with flat grinding, the V-shaped groove has a higher fit, uniform grinding, and no residual burrs, while avoiding large-area wear on the plate surface and effectively protecting the precision of the aluminum strip base material. 6. The downward guide table, together with the guide shell, forms a closed and smooth guide gap, which smoothly guides the narrow strip after slitting, avoiding bending, scratching and jamming of the strip; together with the independent partition, it realizes complete isolation of each channel, further ensuring smooth synchronous feeding of multiple strips, and the equipment has strong operational stability. 7. The width of the grinding table is smaller than that of the pressing platform, and grinding recesses are reserved on both sides to provide sufficient working space for the grinding wheels on both sides, avoid table obstruction and interference, ensure that the grinding mechanism can fully fit the side of the strip, with sufficient grinding stroke and no dead corners, further improving the deburring effect; 8. The supporting processing methods realize standardized linkage operations of feeding and pressing, synchronous cutting, layer guidance, leveling, and double-sided grinding, which can produce high-precision aluminum sheet and strip products with high flatness, no burrs, and uniform size in batches, and are suitable for large-scale precision production.

Detailed Implementation

[0020] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] In this invention, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its normal use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0022] See Figure 1-3The high-precision slitting and deburring integrated device for aluminum sheet and strip shown includes a slitting table 1 with multiple cutting grooves 3 to divide it into multiple flat platforms. A descending guide platform 22, a pressing platform 20, and a grinding platform 2 are sequentially arranged at the rear end of each flat platform. The pressing platform 20 and grinding platform 2 connected to the same descending guide platform 22 have the same height, and a height difference exists between adjacent pressing platforms 20. Sixteen sets of pressing rollers are arranged on the pressing platform 20. Grinding machine sets are installed on both sides of the grinding platform 2. A cutting machine set 7 is installed on the slitting table 1, and pressing mechanisms are arranged on both sides of the cutting machine set 7. The cutting machine set 7 includes a first gantry frame 4, on which a first movable frame 5 driven by a first cylinder 6 is slidably arranged. The cutting machine 7 is installed at the lower end of the first movable frame 5, and the cutting blades installed on the cutting machine 7 are correspondingly arranged with the cutting grooves 3. The pressing mechanism includes a second gantry frame 8, on which a second movable frame 9 driven by a second cylinder 11 is slidably disposed, and a cutting pressure roller 10 is installed at the lower end of the second movable frame 9.

[0023] Through the implementation of the above technical solution, the entire system uses the slitting table 1 as the supporting base. Multiple sets of cutting grooves 3 are evenly opened on the slitting table 1, dividing the table surface into multiple parallel straight platforms, enabling multi-channel parallel slitting operations. Each straight platform is sequentially connected to a descending guide table 22, a pressure platform 20, and a grinding table 2 at its rear end, forming an independent processing channel for a single aluminum strip. Adjacent pressure platforms 20 are designed with varying heights, allowing multiple slid aluminum strips to move in staggered layers in space, fundamentally avoiding problems such as friction, interference, deviation, and overlapping of multiple strips in parallel. The slitting table 1 is equipped with 7 sets of cutting machines and pressing mechanisms on both sides, forming a pre-leveling and precise slitting structure. The pressing mechanism consists of a second gantry frame 8, a second cylinder 11, a second movable frame 9, and a bottom cutting pressure roller 10. It can roll and press the aluminum strip before it enters the cutting area, eliminating strip warping and loosening, and ensuring a flat and stable slitting base surface. The first set of cutting machines 7 drives the first movable frame 5 to rise and fall vertically through the first cylinder 6, which drives the cutting machine 7 and the cutting blade to press down precisely and match with the bottom cutting groove 3 to achieve high-precision longitudinal cutting of aluminum plate and strip, with flat cutting cut and accurate dimensions.

[0024] In this embodiment, the flattening roller group 16 includes side plates 15 installed on both sides of the pressing platform 20, and a height-adjustable flattening roller 16 is installed between the two side plates 15. A guide shell 12 is provided on the downward guide table 22, and a smooth guiding gap 21 is formed between the guide shell 12 and the downward guide table 22. A partition 13 is provided between two adjacent downward guide tables 22; side guard plates 14 are provided on both sides of the cutting table 1, and multiple support columns 17 are provided at the bottom.

[0025] After slitting, multiple independent narrow aluminum strips enter their respective downward guide tables 22. Guide shells 12 are mounted on the outer side of each downward guide table 22, forming a smooth guiding gap 21. This provides a gentle transition for the strips, preventing hard bending, scratches, and jamming. Partitions 13 are installed between adjacent downward guide tables 22 to achieve complete physical isolation between channels, ensuring independent and smooth transport of each aluminum strip. After being guided, the strips enter the pressing platform 20 area. Adjustable-height flattening rollers 16 are installed between the side plates 15 on both sides of the pressing platform 20. These rollers precisely adjust the pressing gap according to the strip thickness and warping degree, performing roller flattening on aluminum strips with stress warping or slight bending after slitting, ensuring complete flatness and providing a high-precision processing benchmark for subsequent deburring processes.

[0026] In this embodiment, the width of the polishing table 2 is smaller than the width of the pressure platform 20, and recesses are formed on both sides. The polishing unit includes a mounting frame 18 and polishing motors 19 mounted at both ends of the mounting frame 18, with polishing wheels mounted on the polishing motors 19. V-shaped polishing grooves are provided on the sides of the polishing wheels.

[0027] The leveled aluminum strip enters the grinding table 2, which is narrower than the pressure platform 20, with working recesses on both sides to provide ample working space for the grinding mechanism. Grinding units are symmetrically arranged on both sides of the grinding table 2, with grinding motors 19 at both ends driving the grinding wheels to rotate at high speed. V-shaped grinding grooves are cut into the sides of the grinding wheels to precisely engage with the cut edges of the aluminum strip, effectively removing burrs, flanges, and sharp edges from both sides of the strip. The grinding is uniform, leaving no burr residue, and does not damage the flat substrate of the aluminum strip, ensuring the finished product's appearance and dimensional accuracy. Alternatively, the grinding motors 19 can be configured to adjust their position along the width direction, allowing for adjustments based on the wear of the grinding wheels, for example, through a self-driven linear movement auxiliary drive.

[0028] This invention also provides a high-precision deburring method for aluminum sheet and strip, using the aforementioned integrated device, comprising the following steps: S1. Place the aluminum strip that needs to be slit and deburred on the slit table 1 and push it forward. The aluminum strip is rolled and pressed by the set pressing mechanism. S2, use 7 sets of cutting machines to cut the aluminum strip, so that each cut aluminum strip enters the corresponding downward guide table 22, pressing platform 20 and grinding table 2 in sequence; S3, the downward guide table 22 guides each slit aluminum strip in layers, the flattened aluminum strip is flattened by the flattening rollers 16, and the burrs on both sides of the aluminum strip are polished by the grinding machine.

[0029] The specific process is as follows: First, the wide aluminum strip to be processed is laid flat on the cutting table 1. The equipment drives the aluminum strip forward at a uniform speed. During the conveying process, the cutting rollers 10 of the pressing mechanism on both sides roll and press the surface of the aluminum strip to achieve feeding leveling, preventing deviation and warping.

[0030] Subsequently, the seven cutting machines press down as a whole, and the cutting blades and cutting grooves 3 are aligned and cooperate to perform multi-blade longitudinal cutting on the wide aluminum strip, cutting a single wide aluminum strip into multiple aluminum strips of equal width and narrow width in one go.

[0031] After being cut, each aluminum strip enters an independent downward guide platform 22. Through the guide gap 21, it achieves stable layered guidance and moves independently without interfering with each other under the action of the staggered channel structure.

[0032] After the aluminum strip enters the pressing platform 20, it is rolled and leveled by 16 sets of adjustable pressing rollers to eliminate shear stress and strip warping deformation, ensuring that the strip is flat and straight.

[0033] Finally, the flat aluminum strip enters the grinding station, where the grinding units on both sides use V-shaped grinding grooves to precisely deburr and chamfer the cut edges on both sides of the strip, completing the integrated processing of cutting, leveling, and deburring, and finally outputting high-precision, burr-free, and highly flat finished aluminum strip.

[0034] This invention breaks through the bottleneck of traditional split-type processing technology. Through multi-channel high and low layer independent conveying, pre-pressing for precise cutting, online roller pressing and leveling, and double-sided V-shaped precision deburring integrated structural design, it realizes efficient, high-precision, and continuous precision processing of aluminum strips. The processing quality is stable, the degree of automation is high, and the versatility is strong, making it suitable for mass production of various high-precision aluminum strips.

[0035] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0036] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not describe the various possible combinations separately.

[0037] Furthermore, various different embodiments of the present invention can be combined in any way, as long as they do not violate the spirit of the present invention, they should also be regarded as the content disclosed by the present invention.
