Description

Technical Field

[0001] This invention relates to a variable disc double 45-degree angle cutting device, which is a special processing equipment for the terminal air outlets of central air conditioning ventilation systems, smoke prevention and exhaust systems, clean air conditioning systems and household air conditioning systems, and belongs to the field of professional equipment for cutting aluminum profiles for air outlets. Background Technology

[0002] Aluminum alloy air vents are widely used in central air conditioning ventilation systems, smoke extraction systems, cleanroom air conditioning systems, and residential air conditioning systems in various buildings and subways, with huge demand. However, for a long time, the processing of aluminum alloy air vents has been a labor-intensive product, with all processes done manually, resulting in low automation and low processing precision. The main reason for this is that the cross-sectional shape of the aluminum profiles for air vents is irregular and the dimensions are varied. The profiles are long and thin, resulting in large deformation, and punching holes in the profiles is required. Unlike conventional profiles such as aluminum profiles for doors and windows, aluminum rods, and aluminum tubes, which have thick walls and closed shapes with minimal deformation, making processing and automation easier, the processing of aluminum alloy air vents has a very low degree of automation. Secondly, manually cutting aluminum profiles of different disc sizes (the cross-sectional width of the aluminum profile) requires frequent changes of material plates of different thicknesses to minimize waste, which is inefficient. At the same time, the accuracy of the cutting dimensions largely depends on manual work, resulting in large errors and low precision, and the processing efficiency urgently needs to be improved. Summary of the Invention

[0003] Purpose of the invention: To address the above-mentioned problems, this invention provides a variable disc double 45-degree angle cutting device, the purpose of which is to improve the automation and precision of aluminum alloy vent processing, while keeping the scrap material head at its minimum size, thereby achieving the goals of saving materials and reducing costs and increasing efficiency.

[0004] Technical solution: A variable disc double 45-degree angle cutting device, comprising: a feeding wheel assembly, a feeding assembly, a main unit base assembly, a variable distance cutting table assembly, a drilling assembly, and a discharge assembly. The feeding wheel assembly includes a rotary material rack, a material pattern disc, a material pattern hole, a material rack support base, a feeding wheel servo motor, a synchronous pulley, and a synchronous belt; the main unit base assembly includes a frame, a frame slider, a material support plate, a material support plate slide rail frame, a material support plate slider, a pneumatic pressure arm, and a sliding shaft pin fixed on the material support plate; the feeding assembly includes a feeding robot, a feeding servo motor, and a robot slide rail platform one; the variable pitch cutting table assembly includes a cutting platform, a saw lifting platform, a lifting cylinder, a lifting slide rail, a platform chassis, a variable pitch servo motor, and the saw lifting platform integrates a cutting power motor, a saw blade bearing seat, and a saw blade, with a variable pitch groove opened on the cutting platform; the drilling assembly includes a drilling motor, a reciprocating cylinder, and a bidirectional drilling position adjustment device; the discharging assembly includes a discharging servo motor, a discharging robot, and a robot slide rail platform two. The working process is as follows: 1. After the equipment starts, the rotary feeding wheel filled with aluminum profiles rotates to the position of the feeding robot under the drive of the servo motor; 2. The feeding robot grips the aluminum profiles and, driven by the servo motor, feeds them along the slide rail platform into the variable-distance cutting table assembly; 3. The variable-distance cutting table assembly has been precisely adjusted to the optimal cutting position according to the profile disc size (cross-sectional width of the aluminum profile) after the equipment starts; the aluminum profiles are gripped and moved forward by the feeding robot. 1. The drilling motor in the drilling assembly starts, and the reciprocating cylinder drives the drilling motor to move forward and backward, completing the drilling process on the profile; 2. After drilling is completed, the pneumatic clamping arm extends to press and fix the aluminum profile on the cutting platform, the cutting saw lifting platform descends, and the high-speed rotating double-headed 45-degree bevel saw blade cuts the profile at a double 45-degree angle. The cutting saw lifting platform rises, the cutting is completed, and the pneumatic clamping arm retracts; 3. The unloading robot arm in the unloading assembly extends to pull out the cut aluminum profile and reset it. This process is repeated continuously.

[0005] Specifically, the feed roller assembly has a rotary feeder with a pattern hole on the pattern plate that is the same as the cross-section of the profile being cut. The aluminum profile passes through the pattern hole and is fixed on the rotary feeder. One rotary feeder can fix multiple profiles. The rotary feeder rotates precisely at a fixed angle under the drive of the servo motor, continuously feeding profiles to the feeding robot.

[0006] Specifically, the aforementioned variable-pitch cutting table assembly is mounted on the frame within the main unit base assembly, connected via a sliding connection. Driven by a variable-pitch servo motor, the variable-pitch cutting table assembly moves back and forth on the frame, thereby achieving precise changes in the cutting disc surface (width of the aluminum profile) to minimize waste material. This also avoids the drawback of frequently changing the material guide plate to minimize waste material when manually cutting with a saw.

[0007] Specifically, the cutting platform of the aforementioned variable-pitch cutting table assembly is provided with a variable-pitch slide groove. The variable-pitch slide groove forms a 45-degree angle with the center line of the cutting platform. One end of the sliding pin is vertically fixed to the material support plate, and the other end extends into the variable-pitch slide groove. The variable-pitch slide groove and the sliding pin form a sliding connection. When the variable-pitch cutting table assembly moves back and forth to change the pitch, the variable-pitch slide groove pushes the sliding pin to move. The direction of movement of the sliding pin is perpendicular to the direction of movement of the variable-pitch slide groove. Under the drive of the sliding pin, the material support plate also moves synchronously to both sides in a direction perpendicular to the direction of movement of the variable-pitch cutting table assembly 4, so that the saw blade on the variable-pitch cutting table assembly and the material support plate always maintain a fixed gap distance and will not touch or damage the material support plate.

[0008] Specifically, the aforementioned support plate and pneumatic clamp are both fixed on the support plate slide rail frame. When the support plate moves, it drives the support plate slide rail frame to move in sync, so that the pneumatic clamp installed on the support plate slide rail frame always maintains a fixed distance from the saw blade on the variable distance cutting table assembly, and will not touch or damage the pneumatic clamp.

[0009] Specifically, the saw blades on the saw lifting platform in the variable-pitch cutting table assembly are two, symmetrically arranged, with each saw blade forming a 45-degree angle with the cutting platform, and the two saw blades forming a 90-degree angle, so that the two ends of each section of aluminum profile being cut are always at a 45-degree angle.

[0010] The beneficial effects of this invention are:

[0011] I. The variable disc double 45-degree angle cutting device of the present invention, wherein the feeding wheel assembly, feeding assembly and discharging assembly can automatically feed, feed and discharge, saving labor and improving processing efficiency.

[0012] II. The variable disc double 45-degree angle cutting device described in this invention has a variable distance cutting table assembly that can be precisely and automatically adjusted to the required disc width (cross-sectional width of the aluminum profile), so that the cut aluminum profile scraps are always kept at the minimum size, greatly saving the waste of raw materials; at the same time, the automatic and precise adjustment of the disc width (cross-sectional width of the aluminum profile) greatly reduces the technical skill requirements of the operator, significantly improves the degree of automation, and improves the processing efficiency.

The material pattern disc 12 has a material pattern hole 17 on its circumference. One end of the rotary material rack 11 is supported by the material rack support base 13, and the other end is supported by the frame 31 of the main machine base assembly 3. The feeding wheel servo motor 14 is also fixed on the frame 31. The feeding wheel servo motor 14 drives the synchronous wheel 15 to rotate through the synchronous belt 16. The synchronous wheel 15 synchronously drives the rotary material rack 11 to rotate. The feeding assembly 2 includes: a feeding robot 21, a feeding servo motor 22, and a robot slide rail platform 23. The feeding robot 21 and the feeding servo motor 22 are integrated and mounted on the robot slide rail platform 23, and are slidably connected to the robot slide rail platform 23. The main unit base assembly 3 includes: frame 31, square rail slider 32, material support plate 33, pneumatic pressure hand 34, sliding shaft pin 35, material support plate slide rail frame 36, and material support plate slider 37. All four square rail sliders 32 are fixed on the frame 31, the sliding shaft pin 35 is fixed on the material support plate 33, and the material support plate 33 and the pneumatic pressure hand 34 are fixed on the material support plate slide rail frame 36. The material support plate slide rail frame 36 is slidably connected to the frame 31 through the square rail sliders 37. The variable pitch cutting table assembly 4 includes: a platform chassis 41, a saw lifting platform 42, a cutting power motor 43, a lifting cylinder 44, a lifting slide rail 45, a saw blade bearing seat 46, a saw blade 47, a variable pitch groove 48, a cutting platform 49, and a variable pitch servo motor 410. The platform chassis 41 is completely mounted on the frame 31 of the main unit base assembly 3 and is slidably connected to the frame 31 by four square rail sliders 32. The saw lifting platform 42, the lifting cylinder 44, the lifting slide rail 45, the cutting platform 49, and the variable pitch servo motor 410 are assembled and installed on the platform chassis 41. The cutting power motor 43, the saw blade bearing seat 46, and the saw blade 47 are integrated and installed on the saw lifting platform 42. The variable pitch groove 48 is opened on the cutting platform 49. The drilling assembly 5 includes: a drilling motor 51, a reciprocating cylinder 52, and a bidirectional drilling position adjustment device 53. The drilling motor 51 is mounted on the reciprocating cylinder 52, and the reciprocating cylinder 52 drives the drilling motor 51 to reciprocate. The bidirectional drilling position adjustment device 53 is mounted on the frame 31, and both the drilling motor 51 and the reciprocating cylinder 52 are mounted on the bidirectional drilling position adjustment device 53, and are adjusted laterally with the direction of movement of the reciprocating cylinder 52. The discharge assembly 6 includes: a discharge servo motor 61, a discharge robot 62, and a second robot slide rail platform 63. The discharge robot 62 and the discharge servo motor 61 are integrated and mounted on the second robot slide rail platform 63, and are slidably connected to the second robot slide rail platform 63.

[0020] Specifically, the rotary material rack 11 in the above-mentioned feeding wheel assembly 1 is a rotary type. The material pattern plate 12 of the material rack is provided with a material pattern hole 17 that is the same as the cross section of the profile being cut. The aluminum profile passes through the material pattern hole 17 and is fixed on the rotary material rack 11. The rotary material rack 11 can fix multiple profiles on one wheel. The rotary material rack 11 rotates precisely at a fixed angle under the drive of the feeding wheel servo motor 14, continuously supplying profiles to the feeding robot 21.

[0021] Specifically, the variable-pitch cutting table assembly 4 is connected to the frame 31 in the main unit base assembly 3 via a sliding connection. Driven by the variable-pitch servo motor 410, the variable-pitch cutting table assembly 4 moves back and forth on the frame 31, thereby achieving precise pitch adjustment of the cutting disc surface (width of the aluminum profile) and minimizing the amount of scrap material cut. This also avoids the drawbacks of frequently changing the material support plate when manually cutting with a saw.

[0022] Specifically, the cutting platform 49 in the aforementioned variable-pitch cutting table assembly 4 is provided with a variable-pitch slide groove 48. The variable-pitch slide groove 48 forms a 45-degree angle with the center line of the cutting platform. One end of the sliding pin 35 is vertically fixed on the material support plate 33, and the other end extends into the variable-pitch slide groove 48. The variable-pitch slide groove 48 and the sliding pin 35 form a sliding connection. When the variable-pitch cutting table assembly 4 moves back and forth to change the pitch, the variable-pitch slide groove 48 pushes the sliding pin 35 to move. The direction of movement of the sliding pin 35 is perpendicular to the direction of movement of the variable-pitch slide groove 48. Under the drive of the sliding pin 35, the material support plate 33 also moves synchronously to both sides in a direction perpendicular to the direction of movement of the variable-pitch cutting table assembly 4, so that the saw blade 47 on the variable-pitch cutting table assembly 4 and the material support plate 33 always maintain a fixed gap distance and will not touch or damage the material support plate 33.

[0023] Specifically, the aforementioned material support plate 33 and pneumatic pressure hand 34 are both fixed on the material support plate slide rail frame 36. When the material support plate 33 moves, it drives the material support plate slide rail frame 36 to move in sync, so that the pneumatic pressure hand 34 installed on the material support plate slide rail frame 36 always maintains a fixed distance from the saw blade 47 on the variable distance cutting table assembly 4, and will not touch or damage the pneumatic pressure hand 34.

[0024] Specifically, the saw blades 47 on the saw lifting platform 42 in the variable distance cutting table assembly 4 are two, symmetrically arranged, with each saw blade 47 forming a 45-degree angle with the center line of the cutting platform 49, and the two saw blades forming a 90-degree angle, so that the two ends of each section of aluminum profile being cut are always at a 45-degree angle.

[0025] The variable disc double 45-degree angle cutting device of the present invention operates as follows: A material template 12 and a synchronous wheel 15 are coaxially mounted on the rotary material rack 11 in the feeding wheel assembly 1. The material template 12 has material template holes 17. The aluminum profile to be cut passes through the material template holes 17 on the material template 12 and is thus fixed. The rotary material rack 11 is supported by a material rack support 13. The feeding wheel servo motor 14 drives the synchronous wheel 15 to rotate via a synchronous belt 16. The synchronous wheel 15 synchronously drives the rotary material rack 11. 1. Rotation; feeding the material to the feeding robot 21 is completed; the feeding robot 21 clamps the aluminum profile, and driven by the feeding servo motor 22, it feeds the aluminum profile into the variable-pitch cutting table assembly 4 along the robot slide rail platform 23; the variable-pitch cutting table assembly 4 is completely seated on the frame 31 of the main unit base assembly 3, and is slidably connected to the frame 31 by the slide rail slider group 32. After the equipment is started, the variable-pitch servo motor 410 drives the variable-pitch cutting table assembly 4 to precisely slide to the optimal cutting position distance to achieve the purpose of minimizing the cutting waste. At the same time, during the movement of the variable-pitch cutting table assembly 4, the variable-pitch slide groove 48 opened on the cutting platform 49 drives the sliding shaft pin 35 on the material support plate 33 to move synchronously. The sliding shaft pin 35 drives the material support plate 33 and the material support plate slide rail frame 36 to move synchronously to both sides, so that the saw blade 47 always maintains a fixed gap distance with the material support plate 33 during the back and forth movement of the variable-pitch cutting table assembly 4. The pneumatic clamping arm 34, mounted on the material guide rail 36, also moves synchronously to both sides, and the saw blade 47 maintains a fixed distance from the pneumatic clamping arm 34. After the aluminum profile is gripped by the feeding robot 21 into the variable-pitch cutting table assembly 4, the drilling motor 51 in the drilling assembly 5 starts, and the reciprocating cylinder 52 drives the drilling motor 51 to reciprocate forward and backward, completing the drilling process on the profile. After drilling is completed, the pneumatic clamping arm 34 extends to press and fix the aluminum profile on the cutting platform 49, the cutting saw lifting platform 42 descends along the lifting rail 45, the high-speed rotating double-headed saw blade 47 cuts the profile, the cutting saw lifting platform 42 rises, the cutting is completed, and the pneumatic clamping arm 34 retracts. The discharge robot 62 in the discharge assembly 6 clamps the cut aluminum profile and, driven by the discharge servo motor 61, moves along the robot arm rail platform 63 to pull out and reset the aluminum profile. This process is repeated cyclically.

[0026] The above description illustrates the structural features, technical principles, and advantages of the present invention. Any improvements and variations that do not depart from the features and principles of the present invention will fall within the scope of protection claimed by the present invention, which is defined by the claims and their equivalents.
