Description

Technical Field

[0001] The utility model relates to the technical field of shearing machines, in particular to a fixed-length shearing device for metal plates. Background Art

[0002] In the metal processing industry, metal plates often need to be cut to length to meet different production needs. This is usually done using a shearing machine. However, the shearing machines currently on the market all have fixed devices for fixing metal plates, which can only process metal plates of a specific size. Their applicability is greatly limited. Moreover, during the cutting process, metal plates are easily deviated in size due to loose fixation or tilted placement, resulting in material waste.

[0003] The prior art CN212551952U discloses a shearing machine for plane cutting, which pushes the metal plate placed on the workbench to the required position by moving the baffle. Because the baffle and the cutter are parallel to each other, the metal plate can be kept parallel to the cutter at all times, and the metal plate will not be tilted. Then the controller controls the second cylinder to extend the second telescopic rod to push the fixed support to the appropriate position. This setting is suitable for metal plates of different sizes. At this time, the controller extends the third telescopic rod through the third cylinder to move the second slider, thereby driving the pressure plate and the extrusion pad to the appropriate position. The four extrusion pads have an anti-slip function and are respectively located at the front, back, left and right positions of the metal plate, which can firmly fix the metal plate to prevent the metal plate from moving during work, causing size deviation in cutting and waste of material.

[0004] For the above-mentioned shearing machine for plane cutting, due to the lack of a continuous feeding mechanism, and the baffle adjusting the position of the metal plate by sliding the slider on a linear track, each adjustment requires manual or automatic control of the baffle movement, the process is relatively slow, and it is difficult to achieve fast and continuous fixed-length shearing.

[0019] The metal plate fixed-length shearing device of the present invention includes a frame 101, a conveyor roller 102, a shearing tool holder 103, a guide rail 104, a movable frame 105, a cylinder 106, a lifting plate 107, an infrared sensor 108, a positioning plate 109, a connecting block 110, a driving motor 111, a driving screw 112, a telescopic rod 113, a guide frame 114, a sliding sleeve 115, a guide plate 116, a locking bolt 117, a limiting groove 118, and a protrusion 119. It solves the problem that the existing technology lacks a continuous feeding mechanism, and the baffle adjusts the position of the metal plate by sliding a slider on a linear track. Each adjustment requires manual or automatic control of the baffle movement, and the process is relatively slow, making it difficult to achieve fast and continuous fixed-length shearing. It is understandable that the above solution can also be used to improve processing efficiency.

[0020] In this embodiment, the conveying roller 102 is a prior art, which is driven by an external driving device and is used to convey the metal plate. The shearing knife holder 103 is arranged in the middle of the conveying roller 102. The shearing knife holder 103 is provided with a cutting knife for shearing the metal plate.

[0021] The guide rail 104 is fixedly connected to the frame 101 and is located on the side of the frame 101 close to the shearing knife frame 103. The movable frame 105 is slidably connected to the guide rail 104 and is located on the side of the guide rail 104 away from the frame 101. The cylinder 106 is installed on the movable frame 105 and is located on the side of the movable frame 105 close to the conveying roller 102.

The lifting plate 107 is fixedly connected and is located on the side of the lifting plate 107 away from the cylinder 106. The adjusting member drives the movable frame 105 to move. The guide rail 104 is installed on the top of the frame 101 along the length direction of the frame 101 to guide the movement of the movable frame 105. The movable frame 105 is U-shaped with an opening facing downward. The movable frame 105 has a slide groove that matches the guide rail 104. The movable frame 105 is installed on the guide rail 104 through the slide groove. The guide rail 104 is mounted on the movable frame 105 and can slide freely along the guide rail 104. The cylinder 106 is vertically mounted on the inner top of the movable frame 105, with the output end facing downward. The lifting plate 107 is fixedly connected to the output end of the cylinder 106. The lifting plate 107 can be driven to move up and down by the extension and contraction of the cylinder 106. The positioning plate 109 is fixedly mounted on the bottom of the lifting plate 107, which can block the movement of the metal plate to achieve fixed-length shearing. The adjusting component is used to drive the movable frame 105 to move. The position of the positioning plate 109 is adjusted by moving the movable frame 105. By adjusting the position of the positioning plate 109, and cooperating with the conveying of the conveying roller 102, automatic and continuous shearing of the metal plate is achieved, which solves the problem that the existing technology lacks a continuous feeding mechanism, and the baffle adjusts the position of the metal plate by sliding a slider on a linear rail. Each adjustment requires manual or automatic control of the baffle movement, and the process is relatively slow, making it difficult to achieve fast and continuous fixed-length shearing.

[0022] Secondly, the connecting block 110 is fixedly connected to the movable frame 105 and is located on one side of the movable frame 105; the driving motor 111 is installed on the frame 101 and is located on the side of the frame 101 close to the connecting block 110; the driving screw 112 is fixedly connected to the output shaft of the driving motor 111 and is threadedly connected to the connecting block 110, and the connecting block 110 has a threaded through hole, and the driving screw 112 is installed on the side of the frame 101 through a bearing bracket, and the driving screw 112 passes through the threaded through hole and is threadedly connected to the connecting block 110, and the driving motor 111 is used to drive the driving screw 112 to rotate, and the driving screw 112 is driven to rotate by the driving motor 111, thereby driving the movable frame 105 to move along the guide rail 104, thereby adjusting the position of the positioning plate 109.

[0023] At the same time, the two ends of the telescopic rod 113 are fixedly connected to the movable frame 105 and the lifting plate 107 respectively. There are two telescopic rods 113, which are respectively arranged on both sides of the cylinder 106. The telescopic rod 113 is extended and retracted as the lifting plate 107 is raised and lowered. Through the telescopic rod 113, the shaking of the lifting plate 107 during raising and lowering is reduced, thereby improving stability.

[0024] In addition, the guide frame 114 is fixedly connected to the frame 101 and is located on the side of the frame 101 close to the shearing blade 103; the sliding sleeve 115 is sleeved on the guide frame 114 and is slidably connected to the guide frame 114; the guide piece 116 is fixedly connected to the sliding sleeve 115 and is located on the side of the sliding sleeve 115 close to the conveying roller 102; the locking bolt 117 extends into the sliding sleeve 115 and is threadedly connected to the sliding sleeve 115.

Sliding the two sliding sleeves 115 can make the two guide pieces 116 be located on both sides of the metal plate, thereby guiding the movement of the metal plate and preventing the metal plate from shifting during the transportation process, affecting the shearing quality. The locking bolt 117 is used to fix the sliding sleeve 115, and the guide piece 116 is used to guide the metal plate.

[0025] Finally, the limiting groove 118 is located on the side of the guide frame 114 close to the sliding sleeve 115; the protrusion 119 cooperates with the limiting groove 118, and the limiting groove 118 is a rectangular groove, which is opened along the length direction of the guide frame 114 and extends from one end to the other end. The protrusion 119 is located on the inner wall of the sliding sleeve 115. Through the cooperation between the protrusion 119 and the limiting groove 118, the sliding sleeve 115 is limited to prevent the sliding sleeve 115 from rotating on the guide frame 114.

[0026] In this embodiment, when in use, according to the need of shearing, the driving motor 111 is controlled to move, so that the positioning plate 109 is moved to the specified position, and then, according to the width of the metal plate, the guide piece 116 is moved to both sides of the metal plate, and the sliding sleeve 115 is fixed by the locking bolt 117. Under the action of the guide piece 116, the metal plate is restricted and can only move in a straight line. After that, the conveying roller 102 is started, and the conveying roller 102 conveys the metal plate. The lifting plate 107 is provided with an infrared sensor 108. When the metal plate approaches the positioning plate 109, the infrared sensor 108 feeds back an electrical signal to the external controller, and the external controller controls the cylinder 106 to move, so that the cylinder 106 extends, driving the positioning plate 109 to move downward to press the metal. The metal plate is blocked, and at the same time, the external controller controls the shearing tool holder 103 to shear the metal plate. After shearing is completed, the external controller controls the cylinder 106 to retract, and the sheared metal plate continues to be conveyed. The shearing tool holder 103 pauses and then opens again, so that there is a certain distance between the subsequent metal plate and the previously sheared metal plate, which is convenient for the infrared sensor 108 to recognize next time. After the shearing tool holder 103 is opened, the conveying roller 102 continues to convey the metal plate, and the process is repeated, thereby realizing fast and continuous fixed-length shearing, solving the problem of the prior art lacking a continuous feeding mechanism, and the baffle adjusts the position of the metal plate by sliding the slider on a linear track. Each adjustment requires manual or automatic control of the baffle movement, and the process is relatively slow, making it difficult to achieve fast and continuous fixed-length shearing.
