Abstract
Description
Technical Field
[0001] This invention belongs to the field of metal sheet post-processing technology, and particularly relates to a method for rapid burr removal from stacked blanking of stamping steel sheets. It is especially suitable for the efficient removal of edge burrs from cold-rolled steel sheets, galvanized steel sheets, etc., in batches using industry-standard equipment after the stamping blanking process, in the form of stacked sheets. Background Technology
[0002] During the blanking and cutting process of steel plates, burrs inevitably form on the edges of the parts due to blanking clearance, cutting edge wear, or fluctuations in process parameters. The presence of burrs not only affects the appearance quality and dimensional accuracy of the parts, but also causes problems such as scratches on the plate surface, die damage, and feeding jams in subsequent stacking, handling, stamping, and assembly processes. In severe cases, it can even cause cuts to operators.
[0003] Currently, commonly used industrial methods for deburring steel plates mainly target single sheets or continuous strips, while specialized processes for deburring entire stacks of blanked steel plates in batches are relatively scarce. Existing related technologies mainly fall into the following categories:
[0004] 1. Manual sanding method: Operators use files, sandpaper, or angle grinders to sand the edges of the entire stack of sheets one by one. This method is extremely labor-intensive and inefficient. The quality of deburring depends entirely on the operator's experience and condition, making it difficult to guarantee consistency. For an entire stack of sheets, the workload of manual processing is even greater, and since the sheets are closely packed together, it is difficult for hand tools to apply even pressure to every layer of the stack's edges.
[0005] 2. Tumbler or Vibratory Grinding: The blanked sheet parts are mixed with abrasive and grinding fluid and placed in a tumbler or vibratory grinding machine. The burrs are removed by the rotation or vibration of the tumbler. This method is suitable for batch processing of small, irregularly shaped parts, but for larger blanked sheets (such as blanked sheets for automotive body panels), extra-large grinding machines are required, resulting in high equipment investment and floor space costs. Furthermore, the grinding media may scratch the sheet surface or wear down surface coatings such as the galvanized layer during prolonged tumbling.
[0006] 3. Sheet-by-sheet deburring method using sanding belts or brush rollers: This method uses sanding belts or brush rollers to feed individual sheets of sheet metal into the equipment. The edges are then ground and deburred by a high-speed rotating sanding belt or brush roller. These machines are sheet-by-sheet type; when processing a stack of sheets, they must first be broken down into individual sheets, processed one by one, and then re-stacked. This adds destacking and stacking processes, resulting in low overall efficiency and making it unsuitable for high-speed stamping blanking lines.
[0007] 4. Sheet metal flipping and vibration method: The entire stack of sheets is clamped and flipped over, using the sheet metal's own weight and mutual displacement to remove some of the burrs. This method has limited effectiveness in removing harder or deeper burrs, and the flipping operation itself carries certain safety risks.
[0008] In summary, existing technologies have the following significant shortcomings when dealing with the specific task of "stacked sheets after blanking":
[0009] (1) It is impossible to efficiently process stacks of boards in batches. Almost all existing equipment adopts a single-sheet through-processing method. The time to process a stack of boards is equal to the processing time of a single sheet multiplied by the number of sheets plus the time for destacking and stacking, which is extremely inefficient.
[0010] (2) The burrs between the layers are interlocked and difficult to reach with surface treatment. After the entire stack of plates is punched and cut, it is naturally stacked and compacted. The burrs between adjacent plates are interlocked and difficult to remove effectively by simply brushing the surface.
[0011] (3) High requirements for plate surface protection, existing methods are prone to causing secondary damage. Blanked plates are usually the precursors of finished parts, and the plate surface quality requirements are strict. Existing grinding or polishing methods are prone to scratching or coating damage to the plate surface during batch processing.
[0012] Therefore, there is an urgent need for a process that can quickly eliminate burrs from a whole stack of boards without relying on specialized custom equipment and using industry-standard equipment. Summary of the Invention
[0013] The purpose of this invention is to provide a method for rapid burr removal during the stacking and blanking of stamping steel plates, aiming to solve the following problems in the prior art:
[0014] The current method of removing burrs from stacks of sheet metal requires individual sheet separation, resulting in extremely low efficiency and incompatibility with high-speed stamping and blanking lines. Burrs between sheets become interlocked, and conventional surface brushing methods are insufficient for thorough removal. Existing batch processing methods easily cause scratches or coating damage to the sheet surface. Furthermore, existing technologies largely rely on specialized, customized equipment, resulting in poor versatility and high barriers to adoption. This invention aims to provide a method for rapidly, thoroughly, and non-destructively removing burrs from the edges of stacks of sheet metal using only industry-standard vibration devices and handheld or mobile electric / pneumatic tools, through a specific combination of process steps and operational sequences.
[0015] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0016] This invention discloses a method for rapid burr removal during the stacking and blanking of stamping steel plates, comprising the following steps:
[0017] Step 1: Clamping and securing the entire stack of sheets
[0018] The stacked steel plates, after being punched and blanked, are transported to the processing station. The height of the stack is H, the thickness of a single steel plate is h, and the number of plates is approximately H / h, where the height is in mm; at least one or more of the four edges of the stacked plates are edges to be processed, formed by punching and shearing.
[0019] Place the entire stack of sheet metal on a general-purpose vibration platform;
[0020] Using a common manual or hydraulic clamping device, a horizontal clamping force is applied from at least two opposite sides of the stack of sheets to fix the stack of sheets horizontally to the vibrating platform; the function of the clamping force is to keep the sheets in contact with each layer but allow a small amount of elastic displacement between the layers, while limiting the horizontal slippage or flying out of a single sheet during the process.
[0021] Step 2: Vibration loosening of interlayer burrs
[0022] Start the vibration platform to apply vertical vibration excitation to the entire stack of sheets in the clamped state; the vibration parameters are set within the adjustable range of the general vibration platform according to the sheet thickness and material:
[0023] Vibration frequency: 30–200 Hz;
[0024] Amplitude: 0.1–1.5 mm;
[0025] Vibration duration: 3–30 seconds;
[0026] Under vibration excitation, each layer of the stack of sheet metal undergoes a slight relative displacement in the vertical direction. The interlayer burrs that were originally interlocked due to punching corner collapse, burr interlacing, etc., undergo repeated micro-dislocation. The burr tips are released from the edge area of adjacent sheet metal and exposed to the outer contour of the stack. During the vibration process, the clamping force is maintained, and the sheet metal only undergoes a slight interlayer elastic displacement caused by vibration in the vertical direction, without any macroscopic movement in the horizontal direction.
[0027] Step 3: Remove burrs from the edges using a mechanical brush.
[0028] After the vibration excitation in step two stops, use an industry-standard rotary brushing tool to mechanically brush and remove burrs from the edges of the entire stack of boards.
[0029] Step 4: Deburring sequence and full edge coverage
[0030] For a stack of sheets with burrs on only one side, complete steps one through three.
[0031] For a stack of sheet metal that requires deburring on multiple sides (such as two long sides or four sides of a rectangular blanking part), perform the operation in the following order:
[0032] First, complete steps one through three for one edge; loosen the clamping device and rotate the entire stack of sheets horizontally on the vibrating platform to the required angle (e.g., 90°); reapply the clamping force and repeat steps two and three to process the next edge; complete all edges to be processed in sequence.
[0033] Step 5: Cleaning and Inspection
[0034] After deburring all the edges to be treated, use a general-purpose compressed air spray gun to blow away the edge areas of the entire stack of sheets to remove residual metal shavings and abrasive debris from the edges and between layers. Then, select at least three sheets from the top, middle, and bottom of the stack and visually inspect or use a magnifying glass to check the edge deburring status.
[0035] Furthermore, the vibration platform is a vibration aging platform, vibration screening platform, or vibration conveying platform commonly used in industrial production, which has the function of adjusting the vibration frequency and amplitude, and the platform size should be larger than the planar size of the entire stack of plates.
[0036] Furthermore, the manual or hydraulic clamping device is a bench vise, an F-clamp, or a hydraulic clamp.
[0037] Furthermore, the rotary brushing tool is an industrially common electric or pneumatic hand-held tool that drives the replaceable brush head to rotate.
[0038] Furthermore, the brush head types include:
[0039] Disc-shaped wire brush, with wire diameter 0.1–0.5 mm;
[0040] Disc-shaped nylon abrasive brush, with silicon carbide or alumina abrasive grains embedded in the nylon matrix, and the abrasive grain size is 80-240 mesh;
[0041] Cup-shaped twisted wire brush.
[0042] Furthermore, the brushing operation method is as follows: Hold the rotating brushing tool by hand or with a robotic arm, and bring the rotating brush head into contact with the edge of the entire stack of sheets to be treated at a certain angle and pressure, moving it back and forth at a uniform speed along the length of the edge; key points of the operation include:
[0043] The brush rotation direction is set so that the bristles move from the inside to the outside of the sheet metal when they contact the edge, scraping away the loose burrs.
[0044] The contact envelope depth between the brush head and the edge of the board is 1 / 4 to 1 / 2 of the diameter or length of the brush bristles;
[0045] The moving speed is controlled at a constant speed of 2-8 m / min, and the entire edge is covered by 1-3 reciprocating motions.
[0046] During operation, keep the brush head axis basically parallel to the edge of the board to be treated, so that the brush bristles act simultaneously on the edge of the multi-layer board from the top to the bottom.
[0047] Furthermore, in step two, when the sheet thickness is 0.4–0.8 mm, the vibration frequency is preferably 80–150 Hz, the amplitude is preferably 0.5–1.0 mm, and the vibration duration is preferably 5–15 seconds; when the sheet thickness is 0.8–1.5 mm, the vibration frequency is preferably 50–100 Hz, the amplitude is preferably 0.3–0.8 mm, and the vibration duration is preferably 5–20 seconds; when the sheet thickness is 1.5–3.0 mm, the vibration frequency is preferably 30–80 Hz, the amplitude is preferably 0.1–0.5 mm, and the vibration duration is preferably 8–30 seconds.
[0048] Furthermore, in step three, the brush head is preferably selected from cup-shaped twisted wire brushes or disc-shaped nylon abrasive brushes. The former has a high efficiency in removing larger metal burrs, while the latter has a more delicate effect on the treatment of fine burrs and coated materials and is less likely to damage the coating.
[0049] Furthermore, in step three, when the height H of the entire stack of boards is greater than 50 mm, it is advisable to use a segmented brushing method: first brush the upper half of the edge, adjust the tool height, and then brush the lower half of the edge to ensure that all edges of the boards from the top to the bottom are fully brushed and covered. There should be a 20% to 30% overlap in height between the brushing segments.
[0050] Furthermore, the vibration platform is a vibration aging platform, whose frequency and amplitude can be precisely set, and it has a timing function. Vibration aging platforms are widely used in the metal processing industry to eliminate residual stress in welded components, and there is a large number of such devices in use. Transferring them to the method of this invention requires no additional equipment investment.
[0051] Furthermore, the rotary brushing tool is an industrially common angle grinder or straight grinder, equipped with replaceable brush heads. Such tools are almost standard equipment in manufacturing workshops, with extremely low procurement and maintenance costs.
[0052] Furthermore, the clamping device is a general-purpose manual quick clamp or hydraulic clamp, which is used daily in stamping workshops and does not require special customization.
[0053] The core technological contribution of this invention lies in the discovery of the key enabling step of "vibration excitation to loosen interlayer burrs," and its combination with "a specific operating method of a general-purpose rotary brush tool," forming a complete and efficient deburring process for entire stacks of sheet metal. This method does not rely on specialized custom equipment at all; all operations can be performed by general stamping operators after simple training.
[0054] Compared with the prior art, the beneficial technical effects of the present invention are as follows:
[0055] 1. It enables batch deburring of entire stacks of sheet metal, improving efficiency by dozens of times compared to processing sheet by sheet.
[0056] This invention uses a stack of sheet metal as the processing unit, combining vibration loosening with brushing to deburr the edges of dozens to hundreds of sheets in a single operation. The processing time for a whole stack is measured in minutes (including several seconds to tens of seconds of vibration and tens of seconds of brushing), while processing each sheet individually takes tens of minutes to several hours, thus increasing efficiency by tens of times and perfectly matching the production cycle of a high-speed stamping blanking line.
[0057] 2. The vibration loosening process solves the core problem of burr jamming between layers of the entire stack of plates.
[0058] This invention innovatively introduces a whole-stack vibration excitation step—a key enabling step for successful whole-stack processing. By using an industry-standard vibration platform to apply micro-amplitude, high-frequency vibration to the clamped stack of sheets, slight relative displacement occurs between each layer, loosening and exposing the interlocking burrs between the sheets, thus providing effective contact conditions for subsequent brushing. This is a technique never before revealed in existing technology.
[0059] 3. It is based entirely on industry-standard equipment and does not rely on any specialized or customized equipment.
[0060] The key feature of this invention is that the vibration platform, rotating brushing tool, and clamping device involved are all standard equipment commonly used in stamping and machining workshops, requiring no special design or customization. This makes the promotion of this method extremely easy, allowing any stamping and blanking company to implement it immediately, with virtually no equipment investment (existing equipment can be used).
[0061] 4. The board surface is well protected, with no corner collapse or coating damage.
[0062] The brushing operation uses a universal rotary brush, allowing operators to flexibly control the contact angle and pressure. When using nylon abrasive brushes or cup-shaped twisted wire brushes to treat coated sheets such as galvanized sheets, the elasticity of the bristles effectively avoids scratching the sheet surface and damaging the coating. During vibration, the sheet remains clamped and constrained in the horizontal direction, preventing macroscopic misalignment and frictional damage to the sheet surface.
[0063] 5. It is easy to operate and easy to train and promote.
[0064] The method has clear operating steps and does not involve complex CNC programming or equipment debugging. It can be mastered by general stamping operators with simple training, facilitating rapid promotion and application within enterprises. Detailed Implementation
[0065] Example 1
[0066] The material to be processed is a stack of cold-rolled steel sheets after stamping and blanking, grade DC04, single sheet thickness 0.7 mm, sheet size 400 mm × 300 mm (rectangular), stack height approximately 140 mm, approximately 200 sheets. All four sides are punched and sheared edges, with continuous burrs of 0.03–0.15 mm in height on the edges, which have a noticeable scraping feel to the touch.
[0067] Equipment used:
[0068] Vibration platform: Commercially available vibration aging platform (model HK-3000, power 1.5 kW, frequency range 0~200 Hz, amplitude adjustable from 0~1.5 mm, table size 1500 mm×1000 mm)
[0069] Clamping device: Two pairs of F-type quick clamps (general hardware tools)
[0070] Brushing tool: Pneumatic angle grinder (8000 r / min), equipped with a 100 mm diameter cup-shaped twisted wire brush (0.3 mm wire diameter).
[0071] Purging tool: Compressed air spray gun
[0072] Operation process:
[0073] (1) Lift the entire stack of boards flat onto the vibrating platform. Use two pairs of F-type clamps to clamp the two short sides of the entire stack of boards respectively. The clamping force should be such that the boards are reliably fixed and do not slip horizontally.
[0074] (2) Set the vibration platform parameters: frequency 100 Hz, amplitude 0.6 mm, timer 15 seconds. Start the vibration platform and observe the entire stack of boards. Slight, blurry vibrations can be seen in the edge area of the boards, indicating that micro-displacement is occurring between the layers.
[0075] (3) After the vibration stops, the operator holds the pneumatic angle grinder and places the rotating cup-shaped twisted wire brush at an angle of about 30° to the edge of one long side of the stack of plates. The rotation direction is from the inside of the plate to the outside. Move it at a constant speed of about 4 m / min along the 400 mm side length, repeating twice to complete the deburring of the long side.
[0076] (4) Loosen the clamps, rotate the stack of sheets 90°, and re-clamp the two short sides. Repeat steps (2) and (3) to process the other long side. Process the two short sides in the same way.
[0077] (5) After the four sides are treated, use a compressed air spray gun to blow along each edge for about 5 seconds.
[0078] (6) Take 3 sheets from the top, middle and bottom of the stack of boards (9 sheets in total) and visually inspect them: all the inspected boards have no visible burrs on the edges, the edges are smooth, and the surface is free of scratches. The edges are smooth to the touch and have no scraping sensation.
[0079] Total processing time: Approximately 5 minutes (including clamping, four vibrations, four brushings, and blowing). Compared to the approximately 50 minutes required for manual sanding of each sheet of the same batch, this represents an efficiency increase of approximately 10 times.
[0080] Example 2
[0081] The material to be processed is a stack of hot-dip galvanized steel sheets, grade DX56D+Z, with a single sheet thickness of 1.2 mm, sheet dimensions of 600 mm × 500 mm, and a stack height of approximately 120 mm, totaling about 100 sheets. The zinc coating must remain undamaged after processing.
[0082] Equipment used:
[0083] Vibration platform: Same as above
[0084] Clamping device: Hydraulic clamp (general purpose)
[0085] Brushing tool: Electric angle grinder (6000 r / min), equipped with a 100 mm diameter disc-shaped nylon abrasive brush (nylon matrix + silicon carbide abrasive grains, 180 mesh).
[0086] Purging tool: Compressed air spray gun
[0087] Operation process:
[0088] The vibration parameters were set to a frequency of 60 Hz, an amplitude of 0.4 mm, and a timing of 20 seconds. A nylon abrasive brush was used for brushing, moving along the edge at a speed of 3 m / min, repeating twice. The remaining operations were the same as in Example 1.
[0089] Treatment Results: Nine sheets were randomly inspected, and all edge burrs were removed. A salt spray test (GB / T10125, neutral salt spray, continuous 48 hours) was performed on the treated edges: no red rust was observed, proving the galvanized layer was intact. The sheet surface was free of scratches.
[0090] Example 3
[0091] The material to be processed is a stack of electro-galvanized steel sheets, grade SECC, with a single sheet thickness of 0.5 mm, sheet dimensions of 300 mm × 200 mm, and a stack height of approximately 250 mm, totaling about 500 sheets. The sheets are thin and stacked high, with fine burrs but extremely high interlayer density.
[0092] Equipment used: Same as in Example 2, but with the addition of upper and lower segmented brushing operations.
[0093] Operation process:
[0094] Vibration parameters: frequency 120 Hz, amplitude 0.8 mm, timing 10 seconds (the thin plates have high interlayer adhesion, and higher frequency and amplitude are adopted to fully loosen them). During brushing, first hold the brushing tool to process the upper half of the edge (approximately in the height range of 0 to 130 mm), then process the lower half (approximately in the height range of 120 to 250 mm), and there is an overlapping area of about 10 mm between the upper and lower sections. Each section is reciprocated twice.
[0095] Treatment effect: 15 sheets are sampled for inspection (5 sheets each at the upper, middle and lower positions), all are qualified, and no burrs remain. There are no scratches on the plate surface and no zinc layer peeling off. The total treatment time is about 8 minutes. Compared with the processing of sheets of the same specification one by one which takes more than 60 minutes, the efficiency is increased by about 8 times. The above-described embodiments are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall all fall within the protection scope defined by the claims of the present invention.
