Description

Technical Field

[0001] This invention relates to a control method for preventing aluminum powder from being pressed into the cut edge of aluminum strip. Background Technology

[0002] When manufacturing aluminum for metal packaging, the material becomes brittle after rolling, and small defects at the edges can easily lead to strip breakage during high-speed cold rolling. Therefore, aluminum strips that have undergone a certain number of rolling passes need to be trimmed. However, because the edges of the aluminum strip contain oil and aluminum powder after cold rolling, improper control during trimming can easily cause the aluminum powder to accumulate and be pressed into the surface of the strip after cold rolling. This results in an increased trimming amount required to remove the powder from the finished product, leading to significant losses.

[0003] The mechanisms underlying oil stain defects are mainly as follows: 1. After the aluminum strip is cold rolled, aluminum powder and oil remain on the surface. When the edges are trimmed, the aluminum powder will adhere to the rubber ring. When the oily part of the aluminum plate comes into contact with the aluminum powder, the aluminum powder on the rubber ring will fall off and adhere to the surface of the aluminum strip. After rolling, aluminum powder is pressed in. 2. When aluminum strip containing oil is sheared, the rolling oil containing aluminum powder accumulates between the blade ring and the strip due to the squeezing of the upper and lower blade rings. When the accumulation reaches a certain level, it is instantly carried away in large quantities due to the influence of the strip shape and other factors. The accumulated oil-containing aluminum powder is pressed into the surface of the aluminum strip during rolling, thus forming a situation where aluminum powder is pressed in. Summary of the Invention

[0004] The purpose of this invention is to provide a control method for preventing aluminum powder from being pressed into the aluminum strip during edge cutting. This control method helps to prevent aluminum powder from being pressed into the aluminum strip during edge cutting.

[0005] The technical solution of the present invention is: a control method for preventing aluminum powder from being pressed into the cut edge of aluminum strip, comprising the following steps: 1) Modify the size and structure of the blade ring in the edge trimming equipment: Design the diameter of both the upper and lower blade rings made of rubber to be less than or equal to the diameter of the edge trimming blade; and design the upper and lower blade rings to be composed of a cylindrical ring and a frustum ring, respectively; 2) Adjust the width and structure of the cutting blade: Design the cutting blade as a stepped disc blade, consisting of a ring-shaped blade and a ring-shaped step with a diameter smaller than the ring-shaped blade; when fitting the blades, the cylindrical ring end faces of the upper and lower blade rings respectively abut against the end faces of the ring-shaped steps on the corresponding cutting blades, and are assembled together on the blade shaft to form a cutting blade ring; 3) Adjust the size of the front and rear tension rollers of the cutting edge ring: Adjust the tension rollers on the front and rear sides of the cutting edge ring from the original Ф80mm to Ф140~160mm; 4) Add a cleaning and lubrication device for the cutting edge ring: By setting a felt and an oil vapor injection device on the biting side of the cutting edge ring, the cutting edge ring can be cleaned in real time; and the ring can be cleaned with a brush to prevent oil and aluminum powder from accumulating into clumps.

[0006] Furthermore, the cylindrical ring diameter of the upper blade ring is 0.5~1mm smaller than the annular blade diameter of the cutting edge, and the cylindrical ring diameter of the lower blade ring is ≤0~0.5mm smaller than the annular blade diameter of the cutting edge.

[0007] Furthermore, the axial width of the cylindrical rings of the upper and lower cutter rings is 18~22mm, and the angle between the sidewall of the frustum ring of the upper and lower cutter rings and the horizontal plane is 14°~16°.

[0008] Furthermore, the width of the annular blade of the cutting blade is adjusted from the original 20mm to 6-8mm, and the diameter of the annular blade is 8-12mm larger than the diameter of the annular step.

[0009] Furthermore, the upper tension roller A and lower tension roller B, located in front of the cutting edge ring, are offset left and right, and the top surface of the lower tension roller B is higher than the bottom surface of the upper tension roller A; the lower tension roller C and upper tension roller D, located behind the cutting edge ring, are offset left and right, and the top surface of the lower tension roller C is higher than the bottom surface of the upper tension roller D; the lower tension roller B and lower tension roller C are positioned between the upper tension roller A and upper tension roller D, with the upper end face of the lower tension roller B flush with the upper end face of the lower tension roller C, and the lower end face of the upper tension roller A flush with the lower end face of the upper tension roller D.

[0010] Furthermore, the felt is disposed on the biting side of the cutting blade ring and contacts the circular surface of the annular blade of the cutting blade and the cylindrical surface of the upper or lower blade ring.

[0011] Furthermore, the oil vapor injection device is located on the upper side of the felt and forms an angle with the surface of the cutting edge ring. The oil vapor injection device blows clean and lubricates the entire surface of the cutting edge ring.

[0012] Furthermore, the oil-vapor injection device uses a mixture of D30 solvent oil and compressed air at a pressure of 1 bar to blow clean and lubricate the cutting blade ring.

[0013] Furthermore, the brush is disposed on the upper side of the oil vapor injection device, and the brush is in contact with the surface of the cylindrical ring and frustum ring of the corresponding upper or lower cutter ring.

[0014] Furthermore, the brush is made of natural pig bristles.

[0015] Compared with the prior art, the present invention has the following advantages: This control method reduces the size of the cutter ring, thereby reducing the contact area between the aluminum strip and the cutter ring. This reduces the adhesion of aluminum powder to the cutter ring and prevents residual rolling oil and aluminum powder from accumulating at the contact point with the cutter ring. This greatly reduces the occurrence of aluminum powder pressing in, thus effectively preventing aluminum powder from pressing in during the cutting of the aluminum strip. Attached Figure Description

Detailed Implementation

[0021] To make the above features and advantages of the present invention more readily understood, specific embodiments are described below in conjunction with the accompanying drawings, but the present invention is not limited thereto. Example 1 (Reference) Figures 1 to 4

[0022] A method for preventing aluminum powder from being pressed into the cut edge of aluminum strip includes the following steps: Step 1) Modify the size and structure of the blade ring 12 in the edge cutting device: Generally, in order to ensure the quality of the cut edge and prevent blade marks, one rubber blade ring is required to have a larger diameter than the edge cutting blade 11 to prevent blade marks, and the other rubber blade ring 12 is required to have a smaller diameter than the edge cutting blade 11 to facilitate strip cutting. However, in the actual cutting process, the upper blade ring and the lower blade ring are in close contact with the strip, resulting in compression.

[0023] Therefore, in order to prevent the rubber blade ring from being squeezed between the rubber blade ring and the aluminum strip 2, thus causing oil stains to accumulate: ① The diameters of the upper and lower blade rings made of rubber are both designed to be ≤ the diameter of the cutting blade 11, that is: the diameter of the cylindrical ring 121 of the upper blade ring is 0.9mm smaller than the diameter of the annular blade 111 of the cutting blade 11, and the diameter of the cylindrical ring 121 of the lower blade ring is ≤ 0.45mm smaller than the diameter of the annular blade 111 of the cutting blade 11.

[0024] ② The original cylindrical upper and lower cutter rings are redesigned to consist of a cylindrical ring 121 and a frustum ring 122. The cylindrical ring 121 has an axial width of 20mm. The remaining portion of the original cylindrical cutter ring is machined into a frustum structure, so that the sidewall of the formed frustum ring 122 forms a 15° angle with the horizontal plane, thereby reducing the contact area between the cutter ring 12 and the aluminum strip 2. See the structure of the cutter ring 12 for details. Figure 1 and Figure 2 The right side of the middle section.

[0025] The advantages of step 1) are: it can reduce the size of the blade ring 12 and reduce the contact between the aluminum strip 2 and the blade ring 12, thereby reducing the adhesion of aluminum powder on the blade ring 12; on the other hand, it avoids the accumulation of residual rolling oil and aluminum powder on the aluminum strip 2 at the contact position with the blade ring 12, and greatly avoids the generation of aluminum powder pressing in.

[0026] The disadvantages of step 1) are: due to the smaller size of the blade ring 12, it may cause blade mark defects on the surface of the aluminum strip 2 (which is resolved through step 2) and localized poor cutting edges caused by the lack of clamping and jumping during the cutting process of the aluminum strip 2 (which is resolved through step 3).

[0027] Step 2) Adjust the width and structure of the cutting blade: The cutting blade 11 is designed as a stepped cylindrical disc blade, consisting of an annular blade 111 and an annular step 112 with a diameter smaller than the annular blade 111. Specifically, the width of the annular blade 111 of the cutting blade 11 is adjusted from the original 20mm to 7mm, and the diameter of the annular blade 111 is 10mm larger than the diameter of the annular step 112. When fitting the blades, the end faces of the cylindrical rings 121 of the upper and lower blade rings respectively abut against the end faces of the annular step 112 on the corresponding cutting blades 11, and are assembled together on the blade shaft to form the cutting blade ring 1.

[0028] By changing the contact width between the original cutting tool and the aluminum strip 2 from 20mm to 7mm in step 2), the normal process waste margin of 10~15mm / side is sufficient to remove the tool marks caused by the reduced ring diameter; at the same time, the local wall thickness of 20mm is retained to take into account the strength requirements of the cutting tool; a part of the cutting tool ring 12 is machined into a cone shape (truncated cone), which not only realizes the functions of unloading and protecting the surface of the strip, but also reduces the contact area to prevent aluminum powder from adhering.

[0029] Step 3) Adjust the size of the front and rear tension rollers of the cutting blade ring 1: Adjust the tension rollers on the front and rear sides of the cutting blade ring 1 from the original Ф80mm to Ф150mm, thereby increasing the wrap angle of the aluminum strip 2 and achieving the stability of the aluminum strip 2 during shearing.

[0030] Specifically, the arrangement structure of the tension rollers is shown in [reference needed]. Figure 3The upper tension roller A6 and lower tension roller B7, located in front of the cutting edge ring 1, are offset to the left and right, with the top surface of the lower tension roller B7 higher than the bottom surface of the upper tension roller A6; the lower tension roller C8 and upper tension roller D9, located behind the cutting edge ring 1, are offset to the left and right, with the top surface of the lower tension roller C8 higher than the bottom surface of the upper tension roller D9; the lower tension roller B7 and lower tension roller C8 are positioned between the upper tension roller A6 and the upper tension roller D9, with the upper end face of the lower tension roller B7 flush with the upper end face of the lower tension roller C8, and the lower end face of the upper tension roller A6 flush with the lower end face of the upper tension roller D9.

[0031] Step 4) Add a cleaning and lubrication device for the cutting edge ring 1: By setting a felt 3 and an oil vapor injection device 4 on the biting side of the cutting edge ring 1, real-time cleaning of the cutting edge ring 1 can be achieved; and the cutting edge ring 12 can be cleaned by a brush 5 to prevent oil and aluminum powder from accumulating into clumps.

[0032] See Figure 4 Specifically, the felt 3 is disposed on the biting side of the cutting blade ring 1 and contacts the circular surface of the annular blade 111 of the cutting blade 11 and the circular surface of the cylindrical ring 121 of the upper or lower blade ring, thereby cleaning the part of the cutting blade ring 1 that contacts the aluminum strip 2 through the felt 3 to prevent aluminum powder from accumulating.

[0033] The aforementioned oil-vapor injection device 4 is positioned on the upper side of the felt 3, forming an angle with the surface of the cutting edge ring 1. The oil-vapor injection device 4 cleans and lubricates the entire surface of the cutting edge ring 1 (including the annular blade 111, annular step 112, cylindrical ring 121, and frustum ring 122). The oil-vapor injection device 4 uses a mixture of D30 solvent oil and compressed air at a pressure of 1 bar to clean and lubricate the cutting edge ring 1.

[0034] The aforementioned brush 5 is positioned on the upper side of the oil and gas injection device 4, and the brush 5 contacts the surface of the corresponding upper or lower blade ring's cylindrical ring 121 and frustum ring 122. The brush 5 is made of natural pig bristles. This allows the brush 5 to clean the blade ring 12, preventing buildup. Example 2

[0035] A method for preventing aluminum powder from being pressed into the cut edge of aluminum strip includes the following steps: Step 1) Modify the size and structure of the blade ring 12 in the edge cutting device: Generally, in order to ensure the quality of the cut edge and prevent blade marks, one rubber blade ring is required to have a larger diameter than the edge cutting blade 11 to prevent blade marks, and the other rubber blade ring 12 is required to have a smaller diameter than the edge cutting blade 11 to facilitate strip cutting. However, in the actual cutting process, the upper blade ring and the lower blade ring are in close contact with the strip, resulting in compression.

[0036] Therefore, in order to prevent the rubber blade ring from being squeezed between the rubber blade ring and the aluminum strip 2, thus causing oil stains to accumulate: ① The diameters of the upper and lower blade rings made of rubber are both designed to be ≤ the diameter of the cutting blade 11, that is: the diameter of the cylindrical ring 121 of the upper blade ring is 0.5mm smaller than the diameter of the annular blade 111 of the cutting blade 11, and the diameter of the cylindrical ring 121 of the lower blade ring is ≤ 0.1mm smaller than the diameter of the annular blade 111 of the cutting blade 11.

[0037] ② The original cylindrical upper and lower cutter rings are redesigned to consist of a cylindrical ring 121 and a frustum ring 122. The cylindrical ring 121 has an axial width of 18mm. The remaining portion of the original cylindrical cutter ring is machined into a frustum structure, so that the sidewall of the formed frustum ring 122 forms a 14° angle with the horizontal plane, thereby reducing the contact area between the cutter ring 12 and the aluminum strip 2. See the structure of the cutter ring 12 for details. Figure 1 and Figure 2 The right side of the middle section.

[0038] The advantages of step 1) are: it can reduce the size of the blade ring 12 and reduce the contact between the aluminum strip 2 and the blade ring 12, thereby reducing the adhesion of aluminum powder on the blade ring 12; on the other hand, it avoids the accumulation of residual rolling oil and aluminum powder on the aluminum strip 2 at the contact position with the blade ring 12, and greatly avoids the generation of aluminum powder pressing in.

[0039] The disadvantages of step 1) are: due to the smaller size of the blade ring 12, it may cause blade mark defects on the surface of the aluminum strip 2 (which is resolved through step 2) and localized poor cutting edges caused by the lack of clamping and jumping during the cutting process of the aluminum strip 2 (which is resolved through step 3).

[0040] Step 2) Adjust the width and structure of the cutting blade: The cutting blade 11 is designed as a stepped cylindrical disc blade, consisting of an annular blade 111 and an annular step 112 with a diameter smaller than the annular blade 111. Specifically, the width of the annular blade 111 of the cutting blade 11 is adjusted from the original 20mm to 6mm, and the diameter of the annular blade 111 is 8mm larger than the diameter of the annular step 112. When fitting the blades, the end faces of the cylindrical rings 121 of the upper and lower blade rings respectively abut against the end faces of the annular step 112 on the corresponding cutting blades 11, and are assembled together on the blade shaft to form the cutting blade ring 1.

[0041] By changing the contact width between the original cutting tool and the aluminum strip 2 from 20mm to 6mm in step 2), the normal process waste margin of 10~15mm / side is sufficient to remove the tool marks caused by the reduced ring diameter; at the same time, the local wall thickness of 20mm is retained to take into account the strength requirements of the cutting tool; a part of the cutting tool ring 12 is machined into a cone shape (truncated cone), which not only realizes the functions of unloading and protecting the surface of the strip, but also reduces the contact area to prevent aluminum powder from adhering.

[0042] Step 3) Adjust the size of the front and rear tension rollers of the cutting blade ring 1: Adjust the tension rollers on the front and rear sides of the cutting blade ring 1 from the original Ф80mm to Ф140mm, thereby increasing the wrap angle of the aluminum strip 2 and achieving the stability of the aluminum strip 2 during shearing.

[0043] Specifically, the arrangement structure of the tension rollers is shown in [reference needed]. Figure 3 The upper tension roller A6 and lower tension roller B7, located in front of the cutting edge ring 1, are offset to the left and right, with the top surface of the lower tension roller B7 higher than the bottom surface of the upper tension roller A6; the lower tension roller C8 and upper tension roller D9, located behind the cutting edge ring 1, are offset to the left and right, with the top surface of the lower tension roller C8 higher than the bottom surface of the upper tension roller D9; the lower tension roller B7 and lower tension roller C8 are positioned between the upper tension roller A6 and the upper tension roller D9, with the upper end face of the lower tension roller B7 flush with the upper end face of the lower tension roller C8, and the lower end face of the upper tension roller A6 flush with the lower end face of the upper tension roller D9.

[0044] Step 4) Add a cleaning and lubrication device for the cutting edge ring 1: By setting a felt 3 and an oil vapor injection device 4 on the biting side of the cutting edge ring 1, real-time cleaning of the cutting edge ring 1 can be achieved; and the cutting edge ring 12 can be cleaned by a brush 5 to prevent oil and aluminum powder from accumulating into clumps.

[0045] See Figure 4 Specifically, the felt 3 is disposed on the biting side of the cutting blade ring 1 and contacts the circular surface of the annular blade 111 of the cutting blade 11 and the circular surface of the cylindrical ring 121 of the upper or lower blade ring, thereby cleaning the part of the cutting blade ring 1 that contacts the aluminum strip 2 through the felt 3 to prevent aluminum powder from accumulating.

[0046] The aforementioned oil-vapor injection device 4 is positioned on the upper side of the felt 3, forming an angle with the surface of the cutting edge ring 1. The oil-vapor injection device 4 cleans and lubricates the entire surface of the cutting edge ring 1 (including the annular blade 111, annular step 112, cylindrical ring 121, and frustum ring 122). The oil-vapor injection device 4 uses a mixture of D30 solvent oil and compressed air at a pressure of 1 bar to clean and lubricate the cutting edge ring 1.

[0047] The aforementioned brush 5 is positioned on the upper side of the oil and gas injection device 4, and the brush 5 contacts the surface of the corresponding upper or lower blade ring's cylindrical ring 121 and frustum ring 122. The brush 5 is made of natural pig bristles. This allows the brush 5 to clean the blade ring 12, preventing buildup. Example 3

[0048] A method for preventing aluminum powder from being pressed into the cut edge of aluminum strip includes the following steps: Step 1) Modify the size and structure of the blade ring 12 in the edge cutting device: Generally, in order to ensure the quality of the cut edge and prevent blade marks, one rubber blade ring is required to have a larger diameter than the edge cutting blade 11 to prevent blade marks, and the other rubber blade ring 12 is required to have a smaller diameter than the edge cutting blade 11 to facilitate strip cutting. However, in the actual cutting process, the upper blade ring and the lower blade ring are in close contact with the strip, resulting in compression.

[0049] Therefore, in order to prevent the rubber blade ring from being squeezed between the rubber blade ring and the aluminum strip 2, thus causing oil stains to accumulate: ① The diameters of the upper and lower blade rings made of rubber are both designed to be ≤ the diameter of the cutting blade 11, that is: the diameter of the cylindrical ring 121 of the upper blade ring is 0.75mm smaller than the diameter of the annular blade 111 of the cutting blade 11, and the diameter of the cylindrical ring 121 of the lower blade ring is ≤ 0.3mm smaller than the diameter of the annular blade 111 of the cutting blade 11.

[0050] ② The original cylindrical upper and lower cutter rings are both redesigned to consist of a cylindrical ring 121 and a frustum ring 122. The cylindrical ring 121 has an axial width of 22mm. The remaining portion of the original cylindrical cutter ring is machined into a frustum structure, so that the sidewall of the formed frustum ring 122 forms a 14° angle with the horizontal plane, thereby reducing the contact area between the cutter ring 12 and the aluminum strip 2. See the structure of the cutter ring 12 for details. Figure 1 and Figure 2 The right side of the middle section.

[0051] The advantages of step 1) are: it can reduce the size of the blade ring 12 and reduce the contact between the aluminum strip 2 and the blade ring 12, thereby reducing the adhesion of aluminum powder on the blade ring 12; on the other hand, it avoids the accumulation of residual rolling oil and aluminum powder on the aluminum strip 2 at the contact position with the blade ring 12, and greatly avoids the generation of aluminum powder pressing in.

[0052] The disadvantages of step 1) are: due to the smaller size of the blade ring 12, it may cause blade mark defects on the surface of the aluminum strip 2 (which is resolved through step 2) and localized poor cutting edges caused by the lack of clamping and jumping during the cutting process of the aluminum strip 2 (which is resolved through step 3).

[0053] Step 2) Adjust the width and structure of the cutting blade: The cutting blade 11 is designed as a stepped cylindrical disc blade, consisting of an annular blade 111 and an annular step 112 with a diameter smaller than the annular blade 111. Specifically, the width of the annular blade 111 of the cutting blade 11 is adjusted from the original 20mm to 8mm, and the diameter of the annular blade 111 is 12mm larger than the diameter of the annular step 112. When fitting the blades, the end faces of the cylindrical rings 121 of the upper and lower blade rings respectively abut against the end faces of the annular step 112 on the corresponding cutting blades 11, and are assembled together on the blade shaft to form the cutting blade ring 1.

[0054] By changing the contact width between the original cutting tool and the aluminum strip 2 from 20mm to 8mm in step 2), the normal process waste margin of 10~15mm / side is sufficient to remove the tool marks caused by the reduced ring diameter; at the same time, a local wall thickness of 20mm is retained to take into account the strength requirements of the cutting tool; a part of the cutting tool ring 12 is machined into a cone shape (truncated cone), which not only realizes the functions of unloading and protecting the surface of the strip, but also reduces the contact area to prevent aluminum powder from adhering.

[0055] Step 3) Adjust the size of the front and rear tension rollers of the cutting blade ring 1: Adjust the tension rollers on the front and rear sides of the cutting blade ring 1 from the original Ф80mm to Ф160mm, thereby increasing the wrap angle of the aluminum strip 2 and achieving the stability of the aluminum strip 2 during shearing.

[0056] Specifically, the arrangement structure of the tension rollers is shown in [reference needed]. Figure 3 The upper tension roller A6 and lower tension roller B7, located in front of the cutting edge ring 1, are offset to the left and right, with the top surface of the lower tension roller B7 higher than the bottom surface of the upper tension roller A6; the lower tension roller C8 and upper tension roller D9, located behind the cutting edge ring 1, are offset to the left and right, with the top surface of the lower tension roller C8 higher than the bottom surface of the upper tension roller D9; the lower tension roller B7 and lower tension roller C8 are positioned between the upper tension roller A6 and the upper tension roller D9, with the upper end face of the lower tension roller B7 flush with the upper end face of the lower tension roller C8, and the lower end face of the upper tension roller A6 flush with the lower end face of the upper tension roller D9.

[0057] Step 4) Add a cleaning and lubrication device for the cutting edge ring 1: By setting a felt 3 and an oil vapor injection device 4 on the biting side of the cutting edge ring 1, real-time cleaning of the cutting edge ring 1 can be achieved; and the cutting edge ring 12 can be cleaned by a brush 5 to prevent oil and aluminum powder from accumulating into clumps.

[0058] See Figure 4 Specifically, the felt 3 is disposed on the biting side of the cutting blade ring 1 and contacts the circular surface of the annular blade 111 of the cutting blade 11 and the circular surface of the cylindrical ring 121 of the upper or lower blade ring, thereby cleaning the part of the cutting blade ring 1 that contacts the aluminum strip 2 through the felt 3 to prevent aluminum powder from accumulating.

[0059] The aforementioned oil-vapor injection device 4 is positioned on the upper side of the felt 3, forming an angle with the surface of the cutting edge ring 1. The oil-vapor injection device 4 cleans and lubricates the entire surface of the cutting edge ring 1 (including the annular blade 111, annular step 112, cylindrical ring 121, and frustum ring 122). The oil-vapor injection device 4 uses a mixture of D30 solvent oil and compressed air at a pressure of 1 bar to clean and lubricate the cutting edge ring 1.

[0060] The aforementioned brush 5 is positioned on the upper side of the oil and gas injection device 4, and the brush 5 contacts the surface of the corresponding upper or lower blade ring's cylindrical ring 121 and frustum ring 122. The brush 5 is made of natural pig bristles. This allows the brush 5 to clean the blade ring 12, preventing buildup.
