Description

Technical Field

[0001] The invention relates to the technical field of aluminum plate cutting, in particular to a cutting machine and a cutting method for aluminum alloy and aluminum plate processing. Background Art

[0002] Aluminum sheet is a common metal material, widely used in curtain walls, lighting and door panels. Aluminum sheet raw materials are processed into large plates in factories, cut into required sizes by cutting equipment and then further processed.

[0003] The hardness index is an important data of aluminum plate. The existing testing equipment usually takes samples on the aluminum plate and then performs hardness testing on a hardness tester. First of all, the number of samples taken in the whole aluminum plate is small, and it is difficult to take samples on a plane. Secondly, the integrity of the aluminum plate will inevitably be destroyed when sampling. When cutting, the aluminum plate at the sampling position needs to be removed. If the sampling position is set randomly, there will inevitably be a sampling hole in the middle of the aluminum plate, which will reduce the number of finished plates of large aluminum plates and increase production costs. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a cutting machine and a cutting method for processing aluminum alloy and aluminum plates.

Initially, the second cutting knife is located in the open groove to form a complete knife body with the cutting knife. The electromagnet can be adsorbed on the cutting knife when it is energized, so that the detector is located in the open groove, and the detector works to detect the surface of the aluminum plate.

[0006] Its beneficial effect is that the hardness of the aluminum plate surface can be tested every time a cut is made. At the same time, the test point is located on the cutting line, which will not damage the surface of the aluminum plate, thereby increasing the number of samples tested and eliminating the sampling work, reducing the loss of aluminum plate materials and reducing production costs.

A support frame is provided on the detector, the electromagnet is provided at the upper end of the support frame, and a second guide column is provided at the lower end of the support frame, and the second guide column is elastically guided and slidably set on the sliding frame.

[0008] In the above scheme, preferably, the cutting machine also includes a movable cutting groove, which includes a U-shaped groove body, a top-contact inclined block and a telescopic device. The U-shaped groove body is slidably guided up and down on the cutting machine. A first inclined surface is provided on the lower end wall of the U-shaped groove body, and the top-contact inclined block is slidably guided on the cutting machine, and a second inclined surface is provided on the top-contact inclined block. The telescopic device is connected to the top-contact inclined block and can push the top-contact inclined block forward a certain amount. The second inclined surface contacts the first inclined surface, causing the U-shaped groove body to rise. When the top-contact inclined block is located below the U-shaped groove body, the upper end surface of the U-shaped groove body is flush with the supporting platform on the cutting machine.

[0009] In the above scheme, preferably, the cutting edge of the cutting knife is aligned with the front end wall of the U-shaped trough body, and the thickness of the cutting knife is consistent with the groove width of the U-shaped trough body. When the cutting knife descends to cut the aluminum plate, the plane of the cutting knife enters into the U-shaped trough body, pushing the edge of the cut aluminum plate to align with the rear end wall of the U-shaped trough body.

[0010] In the above scheme, preferably, the cutting machine also includes a clamping device, which includes a first clamping member and a second clamping member, and the first clamping member and the second clamping member are respectively located on the front and rear sides of the U-shaped trough body. During cutting, the first clamping member presses the aluminum plate, and after cutting is completed, the second clamping member presses the finished plate.

The edge grinding device is arranged on the sliding block, and the sliding block is elastically guided and slidably arranged in a sliding cavity on the side of the cutting machine. A sliding groove is opened on the U-shaped trough body. After the U-shaped trough body descends, the sliding groove is aligned with the sliding cavity, and the sliding block can slide in the sliding groove. When the edge grinding device slides in the sliding groove, the upper and lower cutting edges of the cutting walls of the two aluminum plates that are cut and separated are ground.

[0012] The beneficial effect is that after cutting is completed, the cutting edges of the material plate and the finished plate are ground at the same time to remove cutting burrs and eliminate the dents left by the test, further reducing the impact of the test on the aluminum plate, thereby achieving traceless detection.

The elastic force of the first elastic member is greater than the elastic force of the second elastic member. When the cutting knife rises, the telescopic head extends, and the cutting knife touches the telescopic head, driving the telescopic sliding block to rise, pressing the first elastic member, and at the same time loosening the first pull rope, so that the sliding block slides in the slide groove under the action of the second elastic member. After the cutting knife rises to the set height, the telescopic head retracts, and the telescopic sliding block moves downward under the action of the first elastic member, pulling the first rack to move, causing the wire drum to rotate, and the first pull rope is rewound on the wire groove, and the sliding block returns to its initial position.

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1-Figure 6 A cutting machine for processing aluminum alloy and aluminum plate includes a cutting machine 1 and a detection device 2. The cutting machine 1 includes a cutting knife 11, a movable cutting groove 12, a pressing device 13, a chamfering device 14 and a connecting device 15. The cutting knife 11 is controlled by a hydraulic device to slide up and down on the cutting machine frame. A supporting platform is arranged below the cutting knife 11. The aluminum plate is placed on the supporting platform. The hydraulic device controls the cutting knife 11 to move up and down, thereby completing the cutting of the aluminum plate. An opening groove 111 is provided in the middle position of the cutting knife 11, so that a blade is missing in the middle of the cutting knife 11. The detection device 2 includes a sliding frame 21, a detector 22 and a second cutting knife 23. The sliding frame 21 has front and rear baffles connected by two guide pillars 211. The cutting knife 11 is guided and slidably arranged on the cutting knife 11 by two guide pillars 211, and a second cutting knife 23 is fixedly arranged on the front baffle plate of the sliding frame 21, and a detector 22 is arranged on the rear baffle plate of the sliding frame 21. At the same time, a third elastic member 212 is sleeved on the guide pillar 21, and the two ends of the third elastic member 212 respectively touch the rear baffle plate of the sliding frame 21 and the cutting knife 11, so that in the initial state, under the action of the third elastic member 212, the front baffle plate of the sliding frame 21 touches the front end surface of the cutting knife 11, so that the second cutting knife 23 is embedded in the opening groove 111, so that the second cutting knife 23 and the cutting knife 11 form a complete knife body, and can perform a complete cutting operation on the aluminum plate when the hydraulic device moves downward.

[0027] The detector 22 includes a support frame 222, on which a second guide column 223 is arranged, and the second guide column 223 is guided and slidably arranged on the rear end baffle of the sliding frame 21 through the upper and lower limit limits, and a fourth elastic member is sleeved on the second guide column 223, and the two ends of the fourth elastic member are respectively in contact with the support frame 222 and the sliding frame 21, and the support frame 222 is a portal frame, and a hardness detector is arranged in the middle position of the portal, and a battery iron 221 is arranged at the upper end position of the support frame 222, and the clamping device 13 includes a first clamping member 131 and a second clamping member 132, and the first clamping member 131 and the second clamping member 132 are respectively located on the front and rear sides of the cutting knife 11.

[0028] After the aluminum plate is placed on the support platform of the cutting machine 1, the cutting position of the aluminum plate is aligned with the cutting knife 11 through the moving device. At this time, the first pressing member 131 presses the aluminum plate, and the electromagnet 221 is powered on and started to adsorb on the cutting knife 11, thereby compressing the third elastic member 212, so that the second cutting knife 23 leaves the opening groove 111, and the hardness tester enters the opening groove 111. At the same time, the tip of the ejector pin of the hardness tester is aligned with the cutting edge of the cutting knife 11. At this time, the probe of the hardness tester starts to move downward and touches the aluminum plate, completing the hardness test of the aluminum plate. After completion, the probe rises and returns to its initial position. At this time, the electromagnet 221 is powered off. Under the action of the third elastic member 212, the second cutting knife 23 is embedded in the opening groove 111, so that the second cutting knife 23 and the cutting knife 11 form a complete knife body. At this time, the hydraulic device starts to move downward to cut the aluminum plate. At the same time, while the cutting knife 11 is cutting the aluminum plate downward, the detector 22 is driven to move downward together. The support frame 222 first contacts the surface of the aluminum plate. At this time, the cutting knife 11 continues to descend, and the sliding frame 21 descends together. The support frame 222 remains stationary, and the fourth elastic member is pressed.

[0029] The movable cutting groove 12 includes a U-shaped groove body 121, a top contact inclined block 122 and a telescopic device 123. The U-shaped groove body 121 is arranged on the cutting machine 1 for guiding and sliding upward and downward. A first inclined surface 1211 is arranged on the lower end wall of the U-shaped groove body 121. A guide rail is arranged in the front and rear directions of the frame of the cutting machine 1. The top contact inclined block 122 is arranged on the guide rail for guiding and sliding. At the same time, a second inclined surface 1221 is arranged on the upper end of the top contact inclined block 122. At the same time, the moving direction of the top contact inclined block 122 is perpendicular to the moving direction of the U-shaped groove body 121. The telescopic device 123 is an electric telescopic rod, which is arranged on the frame of the cutting machine 1, and the front end of the telescopic rod is arranged on the top contact inclined block 122. When the U-shaped groove 121 is extended, the top contact inclined block 122 is pushed to move forward, and the second inclined surface 1221 contacts the first inclined surface 1211, so that the U-shaped groove body 121 moves upward. When the lower end plane of the U-shaped groove body 121 presses against the upper end plane of the top contact inclined block 122, the U-shaped groove body 121 no longer rises, and the upper end surface of the U-shaped groove body 121 is flush with the supporting platform of the cutting machine 1, and the cutting edge of the cutting knife 11 is aligned with the front end wall of the U-shaped groove body 121, and the thickness of the cutting knife 11 is consistent with the groove width of the U-shaped groove body 121.

[0030] When the first pressing member 131 presses the aluminum plate, the telescopic device 123 is started to lift the U-shaped trough 121 upward to be level with the supporting platform. At this time, the cutting knife 11 moves downward to complete the cutting of the aluminum plate. At the same time, the cutting knife 11 enters the U-shaped trough 121, so that the cutting edge of the cut finished aluminum plate is aligned with the rear end wall of the U-shaped trough 121. At this time, the second pressing member 132 descends to press the cut finished aluminum plate, so that after each cutting, the gap between the material plate and the finished plate is uniform. After the finished plate is pressed by the second pressing member 132, the telescopic device 123 retracts, so that the U-shaped trough 121 moves downward under the action of gravity, so that the U-shaped trough 121 is out of contact with the aluminum plate.

[0031] The chamfering device 14 includes a sliding block 141, a first pull rope 142 and an edge grinding device 143. The edge grinding device 143 is arranged on the sliding block 141. The sliding block 141 is guided and slidably arranged in a sliding cavity 144 on the side of the cutting machine 1, and a second elastic member 145 is arranged in the sliding cavity 144. The two ends of the second elastic member 145 are respectively in contact with the bottom surface of the sliding cavity 144 and the sliding block 141. The edge grinding device 143 is a grinding wheel motor. A V-groove grinding wheel is arranged on the motor shaft, and the V-groove height of the V-groove grinding wheel is consistent with the thickness center line of the aluminum plate. A slide groove 1212 is opened on the U-shaped groove body 121. After the U-shaped groove body 121 descends, the slide groove 1212 is aligned with the sliding cavity 144. When the sliding block 141 moves on the slide groove 1212, the V-shaped grinding wheel can grind the cutting edges on the material plate and the finished plate at the same time, thereby grinding the upper and lower cutting edges of the cutting walls of the two aluminum plates that are cut and separated.

[0032] The connecting device 15 includes a wire drum 151 and a lifting member 152. The wire drum 151 is rotatably arranged on the frame of the cutting machine 1, and a wire groove 1511 and a gear 1512 are arranged on the wire drum 151. The diameter of the wire groove 1511 is larger than the diameter of the gear 1512. One end of the first pull rope 142 is wound on the wire groove 1511, and the other end is connected to the rear end of the sliding block 141. The lifting member 152 includes a telescopic sliding block 1521, a guide slide groove 1522, a first elastic member 1523, a second pull rope 1524 and a first rack 1526. The guide slide groove 1522 is arranged on the frame of the cutting machine 1 and is located on the side of the cutting knife 11. The telescopic sliding block 1521 is arranged to slide in the guide slide groove 1 522, the first elastic member 1523 is located in the guide slot 1522, and the two ends are respectively in contact with the upper end of the guide slot 1522 and the upper end surface of the telescopic sliding block 1521, the first rack 1523 is guide-slidably arranged on the side of the cutting machine 1, and is meshed with the gear 1512, and one end of the second pull rope 1524 is connected to the upper end surface of the telescopic sliding block 152, and the other end extends outward through the upper end of the guide slot 1522 and is connected to the rear end of the first rack 1523, and the elastic force of the first elastic member 1523 is greater than the elastic force of the second elastic member 145, and a telescopic head 1525 is arranged on the telescopic sliding block 1521, and the telescopic head 1525 is controlled by an electric telescopic rod, which can control its extension or retraction.

[0033] In the initial state, the telescopic head 1525 is in a retracted state. At this time, the telescopic sliding block 1521 is pressed against the lower end of the guide sliding groove 1522 under the action of the first elastic member 1523. At this time, the sliding block 141 is located in the sliding cavity 144, the first pull rope 142 is wound on the wire groove 1511, and the second pull rope 1524 is in a tensioned state.

[0034] After the cutting knife 11 completes the cutting, the U-shaped trough 121 descends, and the internal slide groove 1212 thereof is aligned with the sliding cavity 144, and the telescopic head 1525 extends forward. At this time, the cutting knife 11 begins to rise. When the cutting edge of the cutting knife 11 leaves the surface of the aluminum plate, the cutting knife 11 touches the lower end of the telescopic head 1525. At this time, the cutting knife 11 resets upward and drives the telescopic sliding block 1521 to move upward together, thereby loosening the second pull rope 1524. Therefore, the tension on the wire drum 151 disappears. Under the action of the second elastic member 145, the first pull rope 142 is stretched, and the sliding block 141 slides into the slide groove 1212. Inside, the edge grinding device 143 starts to grind the upper and lower cutting edges of the cutting walls of the two aluminum plates that are cut and separated. When the cutting knife 11 rises to the highest point, the sliding block 141 passes through the entire cutting line of the cutting knife 11. At this time, the telescopic head 1525 retracts, and the telescopic sliding block 1521 moves downward under the action of the first elastic member 1523, and the first rack 1526 is pulled backward by the second pull rope 1524, thereby driving the gear 1512 to rotate, and the wire wheel 1511 rewinds the first pull rope 142, so that the sliding block 141 returns to the sliding cavity 144, so that the second elastic member 145 is in a compressed state again.

[0035] Its working principle or usage is as follows:

[0036] After the aluminum plate is placed on the support platform of the cutting machine 1, the cutting position of the aluminum plate is aligned with the cutting knife 11 through the moving device. At this time, the first pressing member 131 presses the aluminum plate, and the telescopic device 123 is started to lift the U-shaped groove body 121 upward to be level with the support platform. At the same time, the electromagnet 221 is powered on and started to adsorb on the cutting knife 11, thereby compressing the third elastic member 212, so that the second cutting knife 23 leaves the opening groove 111, and the hardness testing machine enters the opening groove 111. At the same time, the tip of the ejector pin of the hardness testing machine is in a straight line with the cutting edge of the cutting knife 11. At this time, the probe of the hardness testing machine starts to move downward and touches the aluminum plate to complete the hardness test of the aluminum plate. After completion, the probe rises and returns to the initial position. At this time, the electromagnet 221 is powered off, and the third elastic member 2 Under the action of 12, the second cutting knife 23 is embedded in the open groove 111, so that the second cutting knife 23 and the cutting knife 11 form a complete knife body. At this time, the hydraulic device starts to descend to cut the aluminum plate, and the cutting knife 11 enters the U-shaped groove body 121. The inclined surface at the lower end of the cutting knife 11 pushes the cut finished aluminum plate to move backward, so that the cutting edge of the cut finished aluminum plate is aligned with the rear end wall of the U-shaped groove body 121. At this time, the second pressing member 132 descends to press the cut finished aluminum plate, so that after each cutting, the gap between the material plate and the finished plate is uniform. After the finished plate is pressed by the second pressing member 132, the telescopic device 123 retracts, so that the U-shaped groove body 121 moves downward under the action of gravity, so that the U-shaped groove body 121 is out of contact with the aluminum plate.

[0037] In the initial state, the telescopic head 1525 is in a retracted state. At this time, the telescopic sliding block 1521 is pressed against the lower end of the guide sliding groove 1522 under the action of the first elastic member 1523. At this time, the sliding block 141 is located in the sliding cavity 144, the first pull rope 142 is wound on the wire groove 1511, and the second pull rope 1524 is in a tensioned state.

[0038] After the cutting knife 11 completes the cutting, the U-shaped trough 121 descends, and the internal slide groove 1212 thereof is aligned with the sliding cavity 144, and the telescopic head 1525 extends forward. At this time, the cutting knife 11 begins to rise. When the cutting edge of the cutting knife 11 leaves the surface of the aluminum plate, the cutting knife 11 touches the lower end of the telescopic head 1525. At this time, the cutting knife 11 resets upward and drives the telescopic sliding block 1521 to move upward together, thereby loosening the second pull rope 1524. Therefore, the tensioning force on the wire drum 151 disappears. Under the action of the second elastic member 145, the first pull rope 142 is stretched, and the sliding block 141 slides into the slide groove 1212. The edge grinding device 143 starts to separate the two cuts. The upper and lower cutting edges of the cutting wall of the aluminum plate are ground. When the cutting knife 11 rises to the highest point, the sliding block 141 passes through the entire cutting line of the cutting knife 11. At this time, the telescopic head 1525 retracts, and the telescopic sliding block 1521 moves downward under the action of the first elastic member 1523, and the first rack 1526 is pulled backward by the second pull rope 1524, thereby driving the gear 1512 to rotate, and the wire wheel 1511 rewinds the first pull rope 142, so that the sliding block 141 returns to the sliding cavity 144, so that the second elastic member 145 is in a compressed state again. At this time, the clamping device 13 is released, and the manipulator or moving device takes away the finished aluminum plate, and everything returns to the initial state.
