Description

Technical Field

[0001] This utility model relates to the field of shearing plate technology, and in particular to an adjustable shearing plate angle locking mechanism. Background Technology

[0002] A shearing machine is a machine that uses one blade to reciprocate linearly relative to another blade to shear sheet metal. It utilizes a moving upper blade and a fixed lower blade, with a suitable blade gap, to apply shearing force to metal sheets of various thicknesses, causing the sheet metal to break and separate to the required dimensions. Shearing machines belong to the category of forging and pressing machinery, primarily used in the metal processing industry. The products are widely used in aerospace, light industry, metallurgy, chemical industry, construction, shipbuilding, automotive, power, electrical appliances, decoration, and other industries, providing the necessary specialized machinery and complete sets of equipment.

[0003] A search revealed a patent with publication number CN220407233U entitled "An Adjustable Angle Shearing Machine for Sheet Metal Processing." The technical problem it addresses is that while the shearing machine body rotates, the actual size of the opening in the machine body shrinks. Consequently, without adjusting the sheet metal, there's a possibility the sheet metal cannot enter the shearing machine body, affecting processing efficiency. Furthermore, the lack of a corresponding limiting structure makes the sheet metal prone to shifting during processing, reducing the quality of the processed sheet metal. The patent addresses this by using a combination of a mounting plate, connecting plate, mounting block, slider, limiting rod, sleeve, worm gear, worm, and servo motor to ensure the upper blade... The upper and lower blades can be synchronously adjusted within the frame, ensuring that the shearing machine can perform normal shearing after the angle adjustment is completed, and the size of the shearing machine opening will not change, ensuring the smooth entry of sheet metal. At the same time, through the cooperation of the support plate, placement plate, adjusting screw, moving block and limit plate, the shearing machine can perform corresponding limit treatment on the sheet metal to be processed, thereby effectively avoiding the problem of sheet metal deviation during processing and improving the quality of sheet metal after processing. However, the following drawbacks still exist and need to be addressed: there is no locking mechanism after the upper blade rotates, which can easily lead to instability of the upper blade when shearing the workpiece, resulting in reduced shearing accuracy, or even workpiece breakage and other problems that affect the quality of the workpiece. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable shear plate angle locking mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable shear plate angle locking mechanism includes a body. Brackets are fixedly installed on the inner walls of both sides of the vertical section of the body, and lower blades are fixedly installed at the top of the two brackets. A discharge port is opened at the lower end of the outer wall of the vertical section of the body, and the brackets and lower blades are both located above the top of the discharge port. A rotating plate is rotatably installed at the top of the body. Limit frames are fixedly installed at the top of the inner walls of both sides of the vertical section of the body. A mounting base is fixedly installed at the bottom of the rotating plate, and an upper blade is fixedly installed at the bottom of the mounting base. Hollow sleeves are fixedly connected to both sides of the rotating plate. The hollow sleeve is fixedly connected to the top and bottom of the sleeve with cover plates. The hollow sleeve has guide openings at both ends. The two cover plates in each column are located on the outer side of the upper and lower ends of the limiting frame. A second drive motor is fixedly installed in the middle of the outer wall of one of the cover plates. A bidirectional lead screw is fixedly installed at the output end of the second drive motor. The upper and lower ends of the bidirectional lead screw are rotatably sleeved with I-shaped frames. The upper and lower ends of the limiting frame have sliding grooves in the middle. Multiple locking blocks are provided on the outer walls of the opposite ends of the two I-shaped frames in each group and on the inner walls of the upper and lower ends of the limiting frame.

[0007] Preferably, a negative pressure chamber is provided inside the horizontal section of the machine body, and a number of adsorption holes are provided at the top of the negative pressure chamber. An air pump is connected to the inlet of the negative pressure chamber through a pipe.

[0008] Preferably, a hanger is fixedly connected to the top center of the rotating plate, the outer walls at both ends of the rotating plate are arc-shaped, a guide groove is opened in the middle of one end of the rotating plate, and multiple toothed blocks at equal angles are fixedly arranged in the middle of the outer wall at one end of the rotating plate.

[0009] Preferably, a limiting frame is fixedly installed on the upper end of the inner wall of one end of the vertical section of the machine body, and a first drive motor is fixedly installed on the top of the limiting frame. A drive gear is rotatably installed inside the limiting frame. The output end of the first drive motor is fixedly installed with the input end of the drive gear, and the circumference of the drive gear meshes with several tooth blocks. The end of the limiting frame is slidably sleeved with the guide groove.

[0010] Preferably, the guide opening is located between the rotating plate and the cover plate, and the I-beam is located between the outer wall of the rotating plate and the inner wall of the limiting frame.

[0011] Preferably, the bidirectional lead screw rotates between the two cover plates and inside the hollow sleeve.

[0012] Preferably, the hollow sleeve is slidably sleeved with the slide groove, and the end of the rotating plate is sleeved with the limiting frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model proposes an adjustable shearing plate angle locking mechanism. The rotating plate is positioned between two limiting frames. When the first drive motor operates, the rotating drive gear drives the rotating plate, mounting base, and upper blade to rotate and tilt via multiple toothed blocks, thereby adjusting the shearing angle on the workpiece. The hollow sleeve moves along two sliding grooves in the same column, and the guide groove rotates with the rotating plate. The position of the limiting frame remains unchanged. Once the shearing angle of the rotating plate, mounting base, and upper blade is reached, the second drive motor operates, causing the two I-beams to move away from each other and press against the upper and lower inner walls of the limiting frames. This helps lock the tilt angle of the upper blade, ensuring the stability of the upper blade's tilt during shearing. Furthermore, multiple locking blocks are provided on the opposite outer walls of the two I-beams in each group and the upper and lower inner walls of the limiting frames. The two sets of locking blocks engage, further enhancing the locking effect after the rotating plate rotates, thus ensuring the stability of the upper blade's tilt.

[0015] This utility model proposes an adjustable shearing plate angle locking mechanism, which has a negative pressure chamber inside the horizontal section of the machine body, and several suction holes at the top of the negative pressure chamber. The inlet of the negative pressure chamber is connected to an air pump through a pipe. When the workpiece is ready to be sheared, the air pump cooperates with the negative pressure chamber to make the several suction holes adsorb the workpiece, thereby increasing the stability of the workpiece during shearing.

Multiple locking blocks 24 are provided on the outer walls of the opposite ends of the two I-shaped frames 21 in each group and on the inner walls of the upper and lower ends of the limiting frame 22.

[0022] In this utility model, a negative pressure chamber 3 is provided inside the horizontal section of the body 1, and a number of adsorption holes 2 are provided at the top of the negative pressure chamber 3. An air pump is connected to the inlet end of the negative pressure chamber 3 through a pipe.

[0023] A hanger 7 is fixedly connected to the top center of the rotating plate 8. The middle of the outer walls at both ends of the rotating plate 8 is arc-shaped. A guide groove 11 is opened in the middle of one end of the rotating plate 8, and multiple tooth blocks 12 with equal angles are fixedly arranged in the middle of the outer wall at one end of the rotating plate 8.

[0024] A limit frame 13 is fixedly installed on the upper end of the inner wall of one vertical section of the body 1, and a first drive motor 14 is fixedly installed on the top of the limit frame 13. A drive gear 15 is rotatably installed inside the limit frame 13.
