[0014] Beneficial effects

[0015] The present invention provides a metal sheet flying shear based on automated control. Compared with the prior art, it has the following advantages:

[0016] (1) Through the setting of the intermittent feeding fixed-length flying shear mechanism, the transmission and feeding of the plate and the flying shear function are integrated. The intermittent feeding flying shear not only realizes the fixed-length flying shear of the plate, but also utilizes its intermittent feeding function to effectively prevent the shearing of multiple sections of plate from being damaged after the flying shear fails, and reserves the reaction time for the staff to shut down the equipment. At the same time, the feeding and flying shear functions can be turned off at the same time, with a high degree of automation and convenient control.

[0017] (2) By setting up the stress scraping component, the scraper scrapes back and forth to remove the stress inside the plate, so that the metal plate can be quickly restored to flatness after being squeezed by the conveying roller to produce a small plastic deformation during transmission, thereby improving the flying shear forming quality of the plate.

[0018] (3) By setting up a quick debonding unit, the scraper will easily generate extra heat after rubbing the plate, which will aggravate the adhesion tendency with the flying shears. The swing of rubber ball one will intermittently squeeze rubber ball two, so that the plate can quickly detach from the flying shears, preventing the two from adhering and improving the flying shearing efficiency.

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The present invention provides three technical solutions, including the following embodiments:

[0030] Example 1

[0031] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 8, a metal sheet flying shear based on automatic control, includes a base plate 1, two vertical plates 2 are fixed on the top of the base plate 1, two vertical plates 3 are fixed on the top of the base plate 1, and a transmission roller 4 is rotatably connected between the opposite sides of the two vertical plates 3. The setting of the transmission roller 4 can facilitate the loading of metal sheets from back to front, and a feeding roller 5 is rotatably connected between the opposite sides of the two vertical plates 2. A protrusion 14 is provided on the feeding roller 5. When the feeding roller 5 rotates, the protrusion 14 contacts the metal sheet, which will exert an extrusion force on the sheet, thereby significantly increasing the friction between the feeding roller 5 and the metal sheet. The use of this friction force enables the metal sheet to be intermittently transmitted and fed, providing a strong guarantee for the precise control of the entire processing process. An intermittent feeding and fixed-length flying shearing mechanism 6 is provided on the vertical plate 2. The intermittent feeding and fixed-length flying shearing mechanism 6 is used to perform flying shearing while intermittently feeding the sheet with a fixed length;

[0032] The intermittent feeding fixed-length flying shear mechanism 6 includes a cross bar 61 rotatably connected between the two vertical plates 2, and a cam 62 is fixed on each of the two cross bars 61. An L-shaped plate 63 is provided at the bottom of each of the two cams 62. The top of the L-shaped plate 63 contacts and squeezes the side surface of the cam 62, and a flying shear 64 is fixed between the bottoms of the two L-shaped plates 63. When the blade of the flying shear 64 completes the flying shear action, it will smoothly enter the knife groove 12, avoiding unnecessary collision between the blade and other components, and greatly extending the service life of the flying shear 64. A reset and anti-warping component 65 is provided on the vertical plate 2 to drive the flying shear 64 to reset and prevent the plate from warping, and an intermittent drive component 66 is provided on the vertical plate 2 to drive the feeding roller 5 to rotate intermittently.

[0033] The reset anti-warping component 65 includes a horizontal plate 651 fixed to one side of the vertical plate 2. The top of the horizontal plate 651 is slidably connected to a pressure rod 652. The bottom end of the pressure rod 652 passes through the horizontal plate 651 and extends to the bottom of the horizontal plate 651. A pressure block 653 is fixed to the bottom end of the pressure rod 652. When the pressure block 653 is pressed down to the bottom, it can press and stabilize the plate to prevent the plate from moving and warping. The bottom of the pressure block 653 is lower than the bottom of the flying shear 64, which improves the stability during flying shearing and improves the flying shear forming quality. The top of the pressure rod 652 is fixed to the bottom of the L-shaped plate 63. The pressure rod 652 is an elastic telescopic rod, which consists of a sleeve, a sleeve rod and a spring. After the pressure rod 652 drives the pressure block 653 to contact the plate, the sleeve rod is compressed into the sleeve and squeezes the spring. After the flying shear is completed, the pressure rod 652 is reset, and the spring resets and pushes the sleeve rod out. A spring 654 is sleeved on the pressure rod 652. The top of the spring 654 is fixed to the bottom of the L-shaped plate 63, and the bottom of the spring 654 is fixed to the top of the horizontal plate 651.

[0034] The intermittent drive assembly 66 includes a motor 661 fixed to one side of the vertical plate 2. The motor 661 is controlled by an external switch and is electrically connected to an external power supply. The motor 661 has the function of adjusting the speed, and this speed directly determines the feeding speed and the flying shear speed of the plate. In the actual production process, the operator can flexibly set the speed of the motor 661 according to different production needs. A gear 1 662 is fixed on the output end of the motor 661. One end of the cross bar 61 passes through the vertical plate 2 and extends to the outside of the vertical plate 2. A gear 2 663 is fixed on the cross bar 61. One side of the vertical plate 2 rotates The gear three 664 is dynamically connected, the gear one 662 is meshed with the gear two 663, the gear two 663 is meshed with the gear three 664, a turntable 665 is fixed on one side of the gear three 664, a rotating arm 666 is fixed on the turntable 665, a boss 667 is fixed on the rotating arm 666, a driving disk 668 is fixed on the transmission shaft of the transmission roller 4, four slide grooves 669 are provided on the driving disk 668, the boss 667 slides in the slide groove 669, and one rotation of the rotating arm 666 can drive the driving disk 668 to rotate a quarter of a circle, thereby driving the feeding roller 5 to rotate a quarter of a circle for intermittent rolling feeding.

[0035] A support platform 11 is fixed on the top of the base plate 1. The setting of the support platform 11 provides stable and reliable support for the flying shear operation. A knife groove 12 is opened on the top of the support platform 11. The setting of the knife groove 12 can reserve a safe flying shear space for the flying shears 64. A collection box 13 is fixed on the top of the base plate 1. The collection box 13 is used to collect the plates after flying shearing, so that the working area remains clean and orderly, which is convenient for subsequent unified processing of the processed plates.

[0036] By setting up the intermittent feeding fixed-length flying shear mechanism 6, the transmission and feeding of the plate and the flying shear function are integrated, and intermittent feeding flying shearing is performed, which not only realizes the fixed-length flying shearing of the plate, but also utilizes its intermittent feeding function to effectively prevent multiple sections of the plate from being damaged after the flying shear 64 fails, and reserves the reaction time for the staff to shut down the equipment. At the same time, the feeding and flying shear functions can be turned off at the same time, with a high degree of automation and convenient control.

[0037] Example 2

[0038] Based on Example 1, see Figure 4-Figure 5As shown, a stress scraping assembly 7 is also provided on the vertical plate 2. The stress scraping assembly 7 is used to scrape and eliminate stress for slight deformation on the plate. The stress scraping assembly 7 includes a rotating wheel 71 rotatably connected to one side of the vertical plate 2. A triangular arc plate 72 is fixed on the rotating wheel 71. A connecting plate 73 is fixed on one side of the vertical plate 2. The top of the connecting plate 73 is rotatably connected to a swing frame 74 through a rotating shaft. An arc rack 75 is fixed on the swing frame 74. One end of the swing frame 74 is rollingly connected to a roller 76. The roller 76 is in rolling contact with the side surface of the triangular arc plate 72. When the rotating wheel 71 rotates, it can drive the triangular arc plate 72 to intermittently contact and squeeze with the roller 76, thereby driving the swing frame 74 to swing intermittently. A fixed seat 77 is fixed on one side of the vertical plate 2.

[0039] A groove 78 is provided on the fixed seat 77, and a movable seat 79 is slidably connected in the groove 78. The size of the movable seat 79 is adapted to that of the groove 78. A straight rack 710 is fixed on one side of the movable seat 79, and the straight rack 710 is engaged with the arc rack 75. A spring 2 711 is fixed between one side of the movable seat 79 and the inner wall of the groove 78. The setting of the spring 2 711 is used to allow the movable seat 79 to be reset horizontally. A folding rod 712 is fixed on the top of the movable seat 79, and a mounting plate 713 is fixed to the bottom end of the folding rod 712. A plurality of scrapers 714 are fixed to the bottom of the mounting plate 713. The bottom of the scraper 714 is in contact with the top of the plate. When the scraper 714 scrapes back and forth, the stress and slight deformation of the plate can be quickly eliminated.

[0040] The rotating wheel 71 and the cross bar 61 are connected by a pulley 8 and a belt 9. The setting of the pulley 8 and the belt 9 links the stress scraping component 7 and the intermittent feeding fixed-length flying shear mechanism 6 together, so that the stress of the plate can be eliminated synchronously during the flying shearing.

[0041] By setting up the stress scraping component 7, the scraper 714 is used to scrape back and forth to scrape away the stress inside the plate, so that the metal plate can be quickly restored to flatness after being squeezed by the transmission roller 4 during transmission and producing slight plastic deformation. The stress scraping component 7 can simultaneously eliminate the stress of the plate, greatly improving the processing efficiency and the flying shear forming quality of the plate.

[0042] Example 3

[0043] Based on Example 2, see Figure 6-Figure 7As shown, a quick debonding unit 10 is provided above the bottom plate 1. The quick debonding unit 10 is specifically used to solve the problem that the scraper 714 easily generates extra heat after rubbing the plate, thereby exacerbating the tendency of the plate to stick to the flying scissors 64. The quick debonding unit 10 includes a fixed rod 101 fixed to the top of the swing frame 74, a fixed plate 102 is fixed to the top of the fixed rod 101, a connecting rod 103 is fixed to the bottom of the fixed plate 102, a rubber ball 104 is fixed to the bottom end of the connecting rod 103, and a vertical pipe 105 is fixed to the top of the bottom plate 1.

[0044] The top of the vertical tube 105 is slidably connected to a slide rod 106, and a circular plate 107 is fixed to the bottom end of the slide rod 106. A spring three 108 is fixed between the bottom of the circular plate 107 and the bottom wall of the vertical tube 105. The setting of the spring three 108 is used to drive the rubber ball two 1010 to reset. The top of the slide rod 106 is fixed to an extension plate 109, and a rubber ball two 1010 is fixed to one side of the extension plate 109. The rubber ball two 1010 and the rubber ball one 104 are set to rubber material to prevent the plate from being damaged by pressure and reduce friction.

[0045] By setting up the quick debonding unit 10, extra heat is easily generated after the scraper rubs the plate, which aggravates the adhesion tendency with the flying shears 64. The rubber ball 104 swings to intermittently squeeze the rubber ball 2 1010. The rubber ball 2 1010 acts on the plate, so that the plate can quickly separate from the flying shears 64, preventing the two from adhering, greatly improving the flying shearing efficiency, and ensuring the efficient and stable operation of the flying shear machine.

[0046] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0047] During operation, the metal sheet is placed on the transmission roller 5, and the motor 661 is started. The motor 611 drives the various gears to cooperate with each other, and then drives the rotating arm 666 to rotate, so that the boss 667 rotates intermittently into the slide groove 669, and then the boss 667 drives the driving disk 668 and the transmission roller 5 to rotate intermittently, thereby driving the sheet to be intermittently loaded. The cross bar 61 drives the cam 62 to rotate while rotating, and then drives the flying shears 64 to move up and down. Through the setting of spring 1 654, the flying shears 64 can be driven to reset upward. When the pressure block 653 moves to the bottom, it presses the sheet to prevent the sheet from moving and tilting, and the flying shears 64 is used to cut the sheet. Flying shear, the plate after flying shearing falls into the collection box 13 for collection, and is driven by the transmission cooperation of the pulley 8 and the belt 9 to drive the wheel 71 to rotate, and then drive the swing frame 74 to swing, and then drive the movable seat 79 to move horizontally back and forth, and then drive the scraper 714 to scrape back and forth on the plate to remove the stress of the plate and flatten the plate. When the swing frame 74 rotates, it synchronously drives the swing plate 102 to swing, and then drives the rubber ball 104 to swing intermittently. After the rubber ball 104 contacts the spherical surface of the rubber ball 2 1010, it drives the rubber ball 2 1010 to press downward, and then the rubber ball 2 1010 is subjected to force to press the plate downward to prevent the plate from sticking to the flying shears 64.

[0048] The above embodiments of the invention are described in detail, but the contents are only preferred embodiments of the invention and should not be considered to limit the scope of the invention. All equivalent changes and improvements made within the scope of the invention should still fall within the scope of the invention.
