Description

Technical Field

[0001] The invention relates to a cutting processing device, in particular to an aluminum plate saw. Background Art

[0002] At present, although a set of highly automated sawing equipment has been formed for sawing aluminum plates, such as a patented CNC cutting saw (Announcement No. CN208680662U), the equipment still uses the traditional clamping and sawing structure;

[0003] When using the traditional clamping structure, when the aluminum plate to be sawed is heavy, if the end clamping part is small, it is easy to cause the aluminum plate to slip when pulling. If the contact length of the clamping part is increased, the width of the clamped waste will also increase greatly. In order to ensure the quality of the processing later, the width of the clamping part needs to be treated as waste.

[0004] When using a traditional sawing structure, the saw blade not only needs to have a rotating cutting action, but also needs to have a lifting action, and the drive motor used to drive the saw blade to rotate often needs to be lifted and lowered under the drive of the jacking cylinder. Therefore, the overall vibration during sawing and the lifting weight that needs to be maintained at all times during vibration use can easily cause damage to the power equipment, thereby reducing the service life of the sawing component. Summary of the invention

[0005] In order to solve the above technical problems, the purpose of the present invention is to provide an aluminum plate saw, which can ensure that the aluminum plate can have a relatively stable sawing effect with a low loss rate on the basis of automated sawing.

[0006] The present invention provides the following technical solutions:

[0007] An aluminum plate saw comprises a working platform and a front feeding platform and a rear feeding frame located on both sides of the working platform, the rear feeding frame is provided with a clamping mechanism, the clamping mechanism is used to pull the aluminum plate dropped onto the front feeding platform backwards into the rear feeding frame, and clamp the end of the aluminum plate to feed forward through the working platform during sawing, the working platform is provided with a passing gap for a saw blade to pass through and move in a straight line to cut the aluminum plate, a main machine base is installed below the working platform for driving the saw blade to rise and move in a straight line, the main machine base comprises a machine base frame, a rotating shaft, a rotating shaft arm, an electrode seat, a driving motor, a spindle seat, a spindle The assembly and the driving cylinder are locked and installed on a group of rotating shafts, the rotating shaft is installed on the machine base frame, the end of the rotating shaft arm is installed with a group of spindle assemblies for fixing the saw blade through the spindle seat adapter, and a group of driving motors are installed on the electrode seat, the driving end of the driving motor is connected to the spindle assembly through a belt, and the axes of the rotation centers of the driving motor, the spindle assembly and the rotating shaft are parallel and not coplanar, one end of the cylinder body of the driving cylinder is hingedly installed on the machine base frame, and the driving end thereof is hingedly installed on the rotating shaft arm;

[0008] At this point, when it is necessary to drive the saw blade to rise and fall, the drive cylinder can be started. The driving action realized by the drive cylinder is to drive the rotating shaft arm, electrode seat, drive motor, and saw blade to rotate synchronously around the rotating axis as a whole. Since the rotating shaft arm, electrode seat, and drive motor are distributed in a triangular structure, the overall structural stability of the composition can be guaranteed to be better. At the same time, the resistance overcome by the driving action of the drive cylinder is greatly reduced compared to the overall vertical lifting of the drive structure, so the loss of the drive cylinder can be greatly reduced.

[0009] Preferably, the machine base frame is also equipped with copper bar guide plates for limiting the position on both sides of the rotating shaft arm, so as to reduce the vibration of the rotating shaft arm during sawing, thereby reducing the loss of the driving cylinder caused by the vibration. Graphite plates for abutting against the copper bar guide plates are also provided on both sides of the rotating shaft arm. Therefore, when the rotating shaft arm rotates around the rotating axis, the wear resistance and smoothness of the friction contact between the rotating shaft arm and the copper bar guide plates can be improved.

[0010] Preferably, the electrode holder is locked and mounted on one end of the rotating shaft, and a group of encoders for monitoring the rotation angle of the rotating shaft are also mounted on the machine base frame at the other end of the rotating shaft through a mounting bracket.

[0011] Preferably, a group of walking frames are also installed on the machine base frame, and the walking frames are slidably installed on the supporting frame under the working platform, and a walking motor is also installed thereon. A driving gear is fixed to the driving end of the walking motor, and a driving rack meshing with the driving gear is also fixed on the supporting frame.

[0012] Preferably, the material clamping mechanism includes a horizontal frame driven by a screw rod for linear reciprocating motion on the rear feeding frame, and a plurality of clamping units are installed side by side on the horizontal frame, and the clamping unit includes two groups of clamping main boards connected by a connecting plate, and a group of clamping cylinders and a group of bending frames are respectively hingedly installed between the two groups of clamping main boards through pin shaft one and pin shaft two. The driving end of the clamping cylinder is also hingedly installed at the bending part of the bending frame for driving the bending frame to swing and rotate around the pin shaft two. A group of upper pressing claws are also fixed on the end of the bending frame away from the pin shaft two. Two groups of lower pressing tongues corresponding to the lower pressure claws are fixed on the clamping main board. When the clamping cylinder starts to push the bending frame to rotate and swing around the pin shaft two, the upper pressing claw is pressed together with the bending frame to rotate and press on the surface of the plate placed on the lower pressing tongue, and the pressing surface of the upper pressing tongue is a plane with claw tooth one, and the pressing surface of the upper pressing claw is an arc surface with claw tooth two.

[0013] During the clamping, since the pressing surface of the upper pressing claw is an arc-shaped surface, it can be pressed more flexibly and firmly on the upper surface of the aluminum plate, and there is no need to change and adjust it according to the thickness of the aluminum plate. The clamp cylinder adopts a top pressing method, and the claw teeth 1 and the claw teeth 2 are in contact with the surface of the aluminum plate, which can further improve the stability of the clamping;

[0014] At the same time, since the clamping mechanism and the main machine base are two components that can cause a high depreciation rate of equipment and plates, by improving the clamping mechanism and the main machine base, the purpose of reducing the double depreciation rate of plates and equipment can be achieved, thereby improving the use efficiency of the equipment.

[0015] Preferably, a group of pressing plates driven to rise and fall by a pressing cylinder are also installed on the working platform. The pressing plates are driven by the pressing cylinder to be pressed against the aluminum plate during sawing, and a front ruler for abutting against one side of the aluminum plate is also provided on one side of the working platform. The front ruler is used to standardize the side position of the forward aluminum plate and cooperate with the pressing and positioning of the aluminum plate during sawing, thereby further improving the accuracy of sawing.

[0016] Preferably, the front feeding table includes a group of fixed tables and at least one group of movable tables, the fixed tables are located on one side of the front ruler, and the movable tables are slidably connected to one side of the working platform, and the ends of each group of movable tables are fixed by a group of pressing cylinders to press one side of the working platform. This method of fixation is not only convenient for positioning, but also easy to increase the number of movable tables to adapt to the sawing of aluminum materials of different widths.

[0017] Preferably, the fixed table, the movable table and the working platform all include a group of air cavities connected to the blower, and a plurality of groups of mounting holes are provided on the horizontal panel at the top of the air cavity, a group of connecting shells are screwed and installed in the mounting holes, the connecting shells have a cylindrical through hole that passes through the air cavity, a group of retaining rings are clamped at the bottom end of the through hole, the bottom end of the spring abuts on the retaining ring, and the top end of the spring is pressed and connected with a group of arc-shaped ball sleeves, a group of stainless steel balls are built in the arc-shaped ball sleeves, the top ends of the stainless steel balls protrude through the connecting shells under the pressure of the springs, and also protrude from the table top of the fixed table, the movable table or the working platform, and by adding an arc-shaped ball sleeve between the stainless steel ball and the spring, the spring will not directly abut against the stainless steel ball, thereby avoiding obstruction of the stainless steel ball when rolling in contact with the bottom surface, thereby ensuring the smoothness of rolling.

[0018] At this time, when the aluminum plate moves, the blower is started to ventilate the air cavity, forming an air film between the aluminum plate and the table top, and then driving the aluminum plate to move, combined with the smoother rolling of the stainless steel ball, the smoothness of the movement of the aluminum plate is further improved.

[0019] The beneficial effects of the present invention are as follows: in the present application, when it is necessary to drive the saw blade to rise and fall, the drive cylinder can be started, and the driving action realized by the drive cylinder is to drive the rotating shaft arm, the electrode seat, the drive motor, and the saw blade to rotate synchronously around the rotating shaft as a whole. Since the rotating shaft arm, the electrode seat, and the drive motor are in a triangular layout structure, the stability of the overall structure can be guaranteed to be better. At the same time, the resistance overcome by the driving action of the drive cylinder is greatly reduced compared with the vertical lifting of the driving structure as a whole, so the loss of the drive cylinder can be greatly reduced; and when the clamp unit is pressed and clamped, since the pressing surface of the upper pressure claw is set as an arc surface, it can be pressed more flexibly and more firmly on the surface of the aluminum plate, and there is no need to change and adjust with the thickness of the aluminum plate. The clamp cylinder adopts a horizontal top pressure method, and the claw tooth one and the claw tooth two are in contact with the surface of the aluminum plate, which can further improve the stability of the clamping; at the same time, since the clamping mechanism and the main base are two components that can cause a high depreciation rate of the equipment and the plate, by improving the clamping mechanism and the main base, the purpose of reducing the double depreciation rate of the plate and the equipment can also be achieved, thereby improving the use efficiency of the equipment.

DETAILED DESCRIPTION

[0032] Example 1

[0033] like Figure 1-9As shown, an aluminum plate saw, in this embodiment, comprises a working platform 1 and a front feeding platform 2 and a rear feeding frame 3 located on both sides of the working platform 1, the rear feeding frame 3 is provided with a clamping mechanism 4, the clamping mechanism 4 is used to pull the aluminum plate dropped onto the front feeding platform 2 backward into the rear feeding frame 3, and clamp the end of the aluminum plate to feed forward through the working platform 1 during sawing, the working platform 1 is provided with a passing gap 5 for a saw blade 7 to pass through and move in a straight line to cut the aluminum plate, and a main frame 6 is installed below the working platform 1 for driving the saw blade 7 to rise and move in a straight line;

[0034] The main machine base 6 includes a machine base frame 61, a rotating shaft 62, a rotating shaft arm 63, an electrode seat 64, a driving motor 65, a spindle seat 66, a spindle assembly 67 and a driving cylinder 68. The rotating shaft arm 63 and the electrode seat 64 are fixedly mounted on a group of rotating shafts 62 by screws, which is also more convenient for disassembly and replacement. The rotating shaft 62 is installed on the machine base frame 61 via a transfer, and a group of spindle assemblies 67 for fixing the saw blade 7 are installed on the end of the rotating shaft arm 63 via a spindle seat 66. A group of driving motors 65 are installed on the electrode seat 64. The driving end of the driving motor 65 is connected to the spindle assembly 67 through a belt, and the axes of the rotation centers of the driving motor 65, the spindle assembly 67 and the rotating shaft 62 are parallel and not coplanar. One end of the cylinder body of the driving cylinder 68 is hingedly mounted on the machine base frame 61, and its driving end is hingedly mounted on the rotating shaft arm 63.

[0035] At this point, when it is necessary to drive the saw blade 7 to rise and fall, the drive cylinder 68 can be started. The driving action realized by the drive cylinder 68 is to drive the rotating shaft arm 63, the electrode seat 64, the drive motor 65, and the saw blade 7 to rotate synchronously around the rotating shaft 62 as a whole. Since the rotating shaft arm 63, the electrode seat 64, and the drive motor 65 are in a triangular distribution structure, the stability of the overall structure can be guaranteed to be better. At the same time, the resistance overcome by the driving action of the drive cylinder 68 is greatly reduced compared to the overall vertical lifting of the driving structure, so the loss of the drive cylinder 68 can be greatly reduced.

[0036] The machine base frame 61 is also equipped with copper bar guide plates 69 for limiting the positions on both sides of the rotating shaft arm 63, so as to reduce the vibration of the rotating shaft arm 63 during sawing, thereby reducing the loss of the driving cylinder 68 caused by the vibration. Graphite plates 610 for abutting against the copper bar guide plates 69 are also provided on both sides of the rotating shaft arm 63. Therefore, when the rotating shaft arm 63 rotates around the rotating axis 62, the wear resistance and smoothness of the friction contact between the rotating shaft arm 63 and the copper bar guide plates 69 can be improved.

[0037] The electrode holder 64 is fixedly mounted on one end of the rotating shaft 62 , and a set of encoders 611 for monitoring the rotation angle of the rotating shaft 62 is also mounted on the machine frame 61 at the other end of the rotating shaft 62 through a mounting bracket.

[0038] A group of walking frames 612 are also installed on the machine base frame 61. The walking frames 612 are slidably installed on the support frame 11 below the working platform 1, and a walking motor 613 is also installed thereon. A driving gear 614 is fixed to the driving end of the walking motor 613, and a driving rack 12 meshingly connected to the driving gear 614 is also fixed on the support frame 11.

[0039] Example 2

[0040] An aluminum plate saw, in this embodiment, is further defined based on embodiment 1, the clamping mechanism 4 includes a horizontal frame 41 driven by a screw rod to reciprocate linearly on the rear feed frame 3, and multiple groups of clamp units 42 are installed side by side on the horizontal frame 41, and the clamp units 42 include two groups of clamp main boards 421 connected by a connecting plate, and a group of clamp cylinders 424 and a group of bending frames 425 are respectively hingedly installed between the two groups of clamp main boards 421 through a pin shaft 1 422 and a pin shaft 2 423, and the driving end of the clamp cylinder 424 is also hingedly installed at the bending position of the bending frame 425 for driving the bending frame 425 around The second pin 423 swings and rotates, and a group of upper pressing claws 426 are fixed to one end of the bending frame 425 away from the second pin 423. Two groups of lower pressing tongues 427 corresponding to the lower part of the upper pressing claws 426 are fixed to the clamp main board 421. When the clamp cylinder 424 starts to push the bending frame 425 to rotate and swing around the second pin 423, the upper pressing claw 426 rotates with the bending frame 425 and is pressed on the surface of the plate placed on the lower pressing tongue 427. The pressing surface of the upper pressing tongue is a plane with a claw tooth 428, and the pressing surface of the upper pressing claw 426 is an arc surface with a claw tooth 429.

[0041] During the clamping, since the pressing surface of the upper pressing claw 426 is an arc-shaped surface, it can be pressed more flexibly and firmly on the upper surface of the aluminum plate, and there is no need to change and adjust it according to the thickness of the aluminum plate. The clamp cylinder 424 adopts a top pressing method, and the claw tooth 1 428 and the claw tooth 2 429 are in contact with the surface of the aluminum plate, which can further improve the stability of the clamping;

[0042] At the same time, since the clamping mechanism 4 and the main base 6 are two components that can cause a high deterioration rate of the equipment and the plate, by improving the clamping mechanism 4 and the main base 6, the purpose of reducing the double deterioration rate of the plate and the equipment can also be achieved, thereby improving the use efficiency of the equipment.

[0043] Example 3

[0044] An aluminum plate saw, in this embodiment, is further limited based on Example 2, and a group of pressure plates 13 driven to rise and fall by a pressure cylinder 14 are also installed on the working platform 1, and the pressure plates 13 are used to be driven by the pressure cylinder 14 to press against the aluminum plate during sawing, and one side of the working platform 1 is also provided with a front ruler 15 for abutting against one side of the aluminum plate, and the front ruler 15 is used for the side position of the standard aluminum plate, and cooperates with the pressing and positioning of the aluminum plate during sawing, so as to further improve the accuracy of sawing.

[0045] The front feeding table 2 includes a group of fixed tables 21 and at least one group of movable tables 22. The fixed tables 21 are located on one side of the front ruler 15, and the movable tables 22 are slidably connected to one side of the working platform 1. The ends of each group of movable tables 22 are pressed against one side of the working platform 1 by a group of pressing cylinders 23 to fix the position of the movable tables 22. This method of fixing is not only convenient for positioning, but also convenient for increasing the number of movable tables 22 to adapt to the sawing of aluminum materials of different widths.

[0046] The fixed platform 21, the movable platform 22 and the working platform 1 all include a group of air cavities 24 connected to the blower 25. A plurality of mounting holes are provided on the top horizontal panel of the air cavity 24. A group of connecting shells 26 are screwed and installed in the mounting holes. The connecting shells 26 have a cylindrical through hole that passes through the air cavity 24. A group of retaining rings 27 are clamped at the bottom end of the through hole. The bottom end of the spring 28 abuts against the retaining ring 27, and the top end thereof is pressed and connected with a group of arc-shaped ball sleeves 29. The arc A group of stainless steel balls 210 are built into the arc-shaped ball sleeve 29. The top of the stainless steel ball 210 protrudes through the connecting shell 26 under the pressure of the spring 28, and also protrudes from the fixed platform 21 or the movable platform 22 or the table surface of the working platform 1. By adding an arc-shaped ball sleeve 29 between the stainless steel ball 210 and the spring 28, the spring 28 will not directly abut against the stainless steel ball 210, thereby avoiding obstruction when the stainless steel ball 210 contacts the bottom surface and rolls, thereby ensuring smooth rolling.

[0047] At this time, when the aluminum plate moves, the blower 25 is started to ventilate the air cavity 24, forming an air film between the aluminum plate and the table top, and then driving the aluminum plate to move, the smoother rolling of the stainless steel ball 210 further improves the smoothness of the aluminum plate movement.

[0048] The working principle of the present invention is: firstly, the aluminum plate raw material is dropped into the front feeding table 2 of the equipment, one end of the aluminum plate raw material is clamped by the clamping mechanism 4 on the rear feeding frame 3, and then the clamping mechanism 4 is started to automatically pull the material into the rear feeding frame 3. After the material is in place, the saw blade 7 is started and automatically rises, and the pressure plate 13 is pressed down synchronously. After the saw blade 7 rises to the right position, the main seat 6 drives the saw blade 7 to start moving forward and start cutting. After the cutting is completed, the pressure plate 13 automatically rises, and the saw blade 7 drops to the lower limit. The clamping mechanism 4 continues to feed forward and continues to perform subsequent cutting operations until the aluminum plate is cut.

[0049] In the present application, when it is necessary to drive the saw blade 7 to rise and fall, the drive cylinder 68 can be started, and the driving action realized by the drive cylinder 68 is to drive the shaft arm 63, the electrode seat 64, the drive motor 65, and the saw blade 7 to rotate synchronously around the rotating shaft 62 as a whole. Since the shaft arm 63, the electrode seat 64, and the drive motor 65 are in a triangular layout structure, the stability of the overall structure can be guaranteed to be better. At the same time, the resistance overcome by the driving action of the drive cylinder 68 is greatly reduced compared with the overall vertical lifting of the driving structure, so the loss of the drive cylinder 68 can be greatly reduced; and when the clamp unit 42 is pressed and clamped, due to the upper The pressing surface of the pressing claw 426 is set as an arc surface, which can press on the surface of the aluminum plate more flexibly and more firmly, and there is no need to change and adjust it according to the thickness of the aluminum plate. The clamping cylinder 424 adopts a horizontal top pressure method, and the claw tooth 1 428 and the claw tooth 2 429 are in contact with the surface of the aluminum plate, which can further improve the stability of the clamping; at the same time, since the clamping mechanism 4 and the main base 6 are two components that can cause a higher depreciation rate of the equipment and the plate, through the improvement of the clamping mechanism 4 and the main base 6, the purpose of reducing the double depreciation rate of the plate and the equipment can also be achieved, thereby improving the use efficiency of the equipment.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
