[0002] In the field of metal processing, the processing of metal skin is of vital importance. Among the many processing links, shearing and trimming the edges of the metal skin is a key step to ensure product quality and smooth subsequent processing. There are many problems with the traditional methods of shearing and trimming the edges of metal skins. For example, manual shearing is not only inefficient, but the shearing accuracy is completely dependent on the experience and skills of the operator, making it difficult to ensure product consistency and high-precision requirements. As an efficient shearing tool, circular shears can theoretically shear and trim both edges of the metal skin at the same time if they are arranged and operated in pairs, greatly improving production efficiency and product quality. However, in existing metal shearing machine technology, it is impossible to shear and trim the two edges of the metal skin by using circular shears arranged in pairs. Summary of the Invention

[0032] like Figure 5-6 As shown;

[0033] The metal shearing machine includes two groups of T-shaped seats 202, and the T-shaped seat 202 is rotatably connected to a rotating shaft 1 204 through a bearing seat. The end of the rotating shaft 1 204 is connected to a disc shear 1 206 through a key. The outer side of the disc shear 1 206 is integrally formed with a cylindrical platform 205. A gantry 210 is vertically slidably connected to the T-shaped seat 202, and the upper part of the gantry 210 is rotatably connected to a rotating shaft 2 209 through a bearing seat. The end of the rotating shaft 209 is connected to a disc shear 2 208 through a key. The disc shear 208 is located above the cylindrical platform 205. There are two groups of T-shaped seats 202, disc shear 1 206 and disc shear 2 208. Therefore, the machine tool has disc shears arranged in pairs. The outer ends of the rotating shaft 1 204 and the rotating shaft 2 209 are connected to couplings. The rotating shaft 1 204 and the rotating shaft 2 209 can be driven to rotate by a motor in the prior art. When shaft 209 rotates, it drives disc shear 208 to rotate. When shaft 1 204 rotates, it drives cylindrical table 205 and disc shear 1 206 to rotate, placing the edge of metal skin 501 between disc shear 208 and disc shear 1 206, driving gantry 210 to slide downward on T-shaped seat 202, and then driving disc shear 208 to approach disc shear 1 206. The inner side of disc shear 208 and the outer side of disc shear 1 206 are in the same plane, and then disc shear 208 approaches disc shear 1 206 to shear the metal skin 501, so that the metal skin 501 is continuously transmitted, and then disc shear 208 and disc shear 1 206 are continuously rotated, thereby shearing the edge of metal skin 501, and then trimming the edge of metal skin 501. The two edges of the metal skin are sheared and trimmed by the disc shears arranged in pairs. The edge of the cut metal skin 501 will fall on the cylindrical platform 205, and the cylindrical platform 205 supports and guides the cut edge.

[0034] like Figure 5-6 As shown;

[0035] The center of the disc shear 208 is connected to the hexagonal prism 211 by a screw, and the center of the rubber wheel 207 is inserted on the hexagonal prism 211. The rubber wheel 207 is located above the disc shear 1 206. A stop pin 212 is inserted on the hexagonal prism 211, and the stop pin 212 blocks the outside of the rubber wheel 207. During the rotation and shearing process of the disc shear 208, the hexagonal prism 211 and the rubber wheel 207 will also rotate. The diameter of the rubber wheel 207 is slightly larger than the disc shear 208, so that the rubber wheel 207 can be pressed on the metal skin 501. As the rubber wheel 207 rotates, the metal skin 501 is driven to move continuously through friction, so that the continuously moving metal skin 501 is continuously sheared; after removing the stop pin 212, the rubber wheel 207 can be easily removed from the hexagonal prism 211, and it is convenient to replace the rubber wheel 207 if it is damaged.

[0036] like Figure 5-6 As shown;

[0037] The lower end of the T-shaped seat 202 is connected to the sliding seat 201 by screws, and two telescopic rods 3 203 are connected to the sliding seat 201 by flanges. The upper ends of the two telescopic rods 3 203 are connected to the lower side of the portal frame 210 by flanges. The sliding seat 201 can support the T-shaped seat 202. The simultaneous extension and contraction of the two telescopic rods 3 203 can drive the portal frame 210 to rise and fall and slide on the T-shaped seat 202, thereby realizing the lifting and lowering of the circular shear 2 208 and the rotating shaft 2 209.

[0038] like Figure 4-6 As shown;

[0039] The two sliding seats 201 are respectively slidably connected to the two ends of the base 101. A track 102 is provided on the base 101. The sliding seats 201 are slidably connected to the track 102. The two sliding seats 201 can slide back and forth on the track 102 on the base 101, thereby adjusting the distance between the two T-shaped seats 202, and then adjusting the distance between the two sets of circular shears, thereby adjusting the position for trimming the edge of the metal skin 501, and controlling the width of the metal skin 501 after final trimming.

[0040] like Figure 5-6 As shown;

[0041] Since both sides of the base 101 are integrally formed with guide ridges 103, the two sides of each sliding seat 201 are respectively fitted with the two guide ridges 103, and both ends of the base 101 are connected to side seats 109 by screws. Each side seat 109 is connected to a telescopic rod 2 108 by a flange, and the ends of the two telescopic rods 208 are respectively connected to the outside of the two T-shaped seats 202 by flanges. The two guide ridges 103 limit the two sides of the two sliding seats 201, so that the two sliding seats 201 are more stable when sliding, and the two sets of circular shears are more stable when moving back and forth, thereby improving the shearing accuracy of the two sets of circular shears; when the two telescopic rods 208 are extended or retracted, they can drive the two T-shaped seats 202 and the two sliding seats 201 to move back and forth.

[0042] like Figure 4-8 As shown;

[0043] Since one side of the base 101 is connected to two support bars 304 by screws, the two ends of the beam 301 are respectively welded to the two support bars 304, and the upper side of the beam 301 is flush with the uppermost side of the two disc shears 206. Before the metal skin 501 enters the two sets of disc shears, it needs to be placed on the upper side of the beam 301. The beam 301 supports the metal skin 501 so that the metal skin 501 can remain flat and enter between the two sets of disc shears to ensure the shearing quality.

[0044] like Figure 7-8 As shown;

[0045] Since both ends of the beam 301 are slidably connected to a hand-moving seat 303, each hand-moving seat 303 is connected to a fastening screw 305 by a thread, and the fastening screw 305 presses on the beam 301 to fix the hand-moving seat 303 on the beam 301, the hand-moving seat 303 is vertically slidably connected to the slide 302, and the lower end of the slide 302 is connected to the pressure wheel 306 through an axis rotation. The pressure wheel 306 is located on the upper side of the beam 301, and the upper part of the slide 302 is welded with the upper end of the tension spring, and the lower end of the tension spring is welded to the upper part of the hand-moving seat 303. Both hand-moving seats 303 can It moves back and forth on the crossbeam 301, thereby driving the two hand shift seats 303 to move to the front and rear edges of the metal skin 501 respectively, limiting the metal skin 501 and preventing the metal skin 501 from moving back and forth on the crossbeam 301 at will, thereby ensuring the stability of the metal skin 501 during transmission; the slide 302 is always subjected to the downward force of the tension spring, so that the pressure wheel 306 always has downward pressure, so that the pressure wheel 306 always presses on the upper side of the metal plate, and the two pressure wheels 306 always press on the two edges of the upper side of the metal plate, preventing the metal plate from bouncing at will during transmission and affecting the shearing operation.

[0046] like Figure 5-6 and 9-10;

[0047] Since each of the sliding seats 201 is connected to an L-shaped rod 407 by screws, a hollow seat 401 is welded to the end of the L-shaped rod 407, a vertical sliding connection is provided on the hollow seat 401, the upper part of the vertical column 402 is connected to the inclined block 405 by screws, a telescopic rod 406 is connected to the hollow seat 401 by a flange, the upper end of the telescopic rod 406 is connected to the lower side of the inclined block 405 by a flange, the inner side of the inclined block 405 is threadedly connected to the round seat 404, the outer side of the inclined block 405 is provided with an inclined surface, and a vertical blade 403 is provided on the side of the inclined block 405 facing the disc shear 206. After the front and rear edges of the metal sheet 501 are sheared, two shear seams are formed on the metal sheet 501. When the sliding seat 201 slides, it drives the L-shaped rod 407, the hollow seat 401, the vertical column 402, and the inclined block 405 to move synchronously, so that the inclined block 405 is always located at the lower side of the shear seam. After the telescopic rod 406 is extended, it drives the inclined block 405 to move upward, and then drives the inclined block 405 to be inserted into the shear seam. The inclined surface of the inclined block 405 drives the cut edges of the metal sheet 501 to separate outward. The two edges of the sheared metal sheet 501 will fall on the two round seats 404 and continue to move, making it easier for the metal sheet 501 to separate from the cut edges. The vertical blade 403 and the inclined surface of the inclined block 405 can both be inserted into the shear seam, and then drive the cut edges of the metal sheet 501 to separate outward, making it easier for the cut edges of the metal sheet 501 to separate outward.

[0048] like Figure 4 and 7 -8 shown;

[0049] Since two L-shaped frames 104 are connected to the side of the base 101 away from the crossbeam 301 by screws, each L-shaped frame 104 is vertically slidably connected to a vertical rod 106, and the two ends of the round rod 107 are respectively welded to the upper ends of the two vertical rods 106. Each L-shaped frame 104 is connected to a telescopic rod 105 through a flange, and the end of the telescopic rod 105 is connected to the lower end of the vertical rod 106 through a flange. The round rod 107 is located on one side of the two inclined blocks 405, and the round rod 107 is located on the side close to the vertical blade 403. The two telescopic rods 105 respectively drive the two vertical rods 106 to move downward, and then drive the round rod 107 to move downward, and the metal skin 501 is pressed down by the round rod 107. After being pressed down, the shear seam on the metal skin 501 is easier to insert into the inclined block 405, which makes it more convenient for the inclined block 405 to separate the cut edges of the metal skin 501 outward.

[0050] Furthermore, in a preferred embodiment, the connection between the L-shaped rod 407 and the hollow seat 401 is changed to an elastic connection. For example, an elastic element such as a spring or a rubber pad is installed at the portion where the L-shaped rod 407 is connected to the hollow seat 401. In this way, when the sliding seat 201 encounters vibration or instability during movement, the elastic connection can play a buffering role, avoiding excessive impact on the position of the inclined plane block 405. The telescopic rod 406 drives the inclined plane block 405 upward to insert into the shear seam. The elastic connection ensures that the inclined plane block 405 can still function well under complex working conditions, driving the cut edges of the metal skin 501 to separate outward, thereby improving the adaptability of the device in different working environments.

[0051] Furthermore, in a preferred embodiment, an adsorption device, such as a small vacuum suction cup or an electromagnetic suction cup (for magnetic metal skin 501), is installed on the round seat 404. The adsorption device can gently adsorb the edge of the sheared metal skin 501 on the round seat 404, further facilitating the separation of the metal skin 501 from the cut edge. After the metal skin 501 is sheared, its edge falls on the round seat 404 equipped with the adsorption device. The adsorption device is started to gently adsorb the edge of the metal skin 501. At the same time, the inclined block 405 or the vertical blade 403 is inserted into the shear seam to drive the cut edge to separate outward. Since the metal skin 501 is gently adsorbed, the separation process is more stable, and the cut edge can be separated from the main body of the metal skin 501 more smoothly, thereby improving the separation efficiency and quality.

[0052] Furthermore, in a preferred embodiment, the bevel of bevel block 405 is designed to have an adjustable angle, as is conventionally done. For example, an angle adjustment mechanism is provided within bevel block 405, allowing the angle of the bevel to be changed by rotating a screw or other means. This allows the bevel angle of bevel block 405 to be flexibly adjusted to suit the thickness and material of metal sheets 501, thereby achieving the optimal separation effect. Before shearing different types of metal sheets 501, the angle of bevel block 405 is adjusted based on their characteristics using the angle adjustment mechanism. After the metal sheet 501 is sheared to form a shear seam, the sliding seat 201 drives the bevel block 405 to the underside of the shear seam, and the telescopic rod 406 is extended to insert the bevel block 405 into the shear seam. Because the bevel angle is optimized, it can drive the cut edge outward with the most appropriate force and angle for the current metal sheet 501, improving the device's adaptability to processing different types of metal sheets.

[0053] A method for using a metal shearing machine tool comprises the following steps:

[0054] S1: Place the metal sheet 501 on the upper side of the beam 301 and adjust the two hand-moving seats 303 to contact the two edges of the metal sheet 501 respectively;

[0055] S2: The two pressing wheels 306 are pressed against the front and rear edges of the metal sheet 501 respectively;

[0056] S3: Push the two edges of the metal sheet 501 into the space between the two sets of disc shears 1 206 and disc shears 208 respectively;

[0057] S4: The disc shear 208 and the rubber wheel 207 rotate synchronously, and the rubber wheel 207 continuously drives the metal sheet 501 to move;

[0058] S5: Cutting the two edges of the metal skin 501 by two sets of disc shears 1 206 and disc shears 2 208;

[0059] S6: driving the two inclined blocks 405 to be inserted into the two cutting seams to separate the metal skin 501 from the cut edges on both sides.
