[0002] With the rapid development of modern industrial technology, the requirements of the processing industry for processing equipment are increasing day by day. As one of the important equipment in the processing industry, shearing machines are widely used in the field of cutting materials. There is a rotary shearing machine. The material will be cut when it passes between the rotating upper and lower blades. The operator can make the shearing machine suitable for materials of different thicknesses by adjusting the horizontal distance between the upper and lower blades in the vertical state, avoiding increased tool wear due to excessive or insufficient distance between the upper and lower blades.

[0003] However, there are many problems with manually adjusting the position of the tool by the operator. Since there are a large number of shearing machines during production and processing, manual adjustment is time-consuming and inefficient, affecting the production efficiency of the product. In addition, the accuracy of manual adjustment is affected by the operator's tool adjustment level. When the operator is not skilled in tool adjustment, it not only increases the tool adjustment time, but also increases tool wear. Utility Model Content

[0004] In view of this, the utility model provides a shearing machine capable of automatically adjusting the blade to solve the above problem.

[0005] A shearing machine capable of automatic blade adjustment comprises a shearing machine body and at least one blade adjustment assembly mounted on the shearing machine body. The shearing machine body comprises a housing, an upper blade assembly rotatably mounted on the housing, a lower blade assembly rotatably mounted on the housing, and a drive assembly mounted on the housing for controlling the rotation of the upper and lower blade assemblies. The upper blade assembly comprises an upper blade shaft and an upper blade mounted on the upper blade shaft. The blade adjustment assembly comprises two mounting plates mounted on the upper blade assembly, a main guide rod horizontally disposed between the two mounting plates, a drive block movably mounted on the exterior of the main guide rod, a linear servo motor mounted on one side of the upper blade assembly for driving the drive block, a slave guide rod horizontally disposed between the two mounting plates and located at the bottom of the main guide rod, a slave block movably mounted on the slave guide rod, and a spring mounted on each slave guide rod and located at one end of each slave block. The driver block has an upper inclined surface on the side facing the slave block, and the slave block has a lower inclined surface on the side facing the driver block. The upper and lower inclined surfaces have the same angle with the horizontal plane. The driving block is controlled to move along the main guide rod so that the upper inclined surface abuts against the lower inclined surface, thereby driving the driven block to move along the guide rod. The upper blade is fixedly arranged on one side of the driven block.

[0006] Furthermore, the angle between the inclined plane and the horizontal plane is an acute angle.

[0007] Furthermore, the spring is arranged at one end of the driven block away from the linear servo motor.

[0008] Furthermore, the end of the upper blade extends out of the mounting plate.

[0009] Furthermore, the angle between the inclined surface direction of the upper inclined surface and the extension direction of the driving end of the linear servo motor is an acute angle.

[0010] Furthermore, the height of the top of the upper slope is not lower than the height of the top of the lower slope, the height of the bottom of the upper slope is not higher than the height of the bottom of the lower slope, and the width of the upper slope is not less than the width of the lower slope.

During the controlled movement of the driving block, the upper inclined surface abuts against the lower inclined surface and the driven block moves synchronously with the driving block. The two springs are respectively squeezed and stretched to drive the driven block to return when the driving block retreats so that the driven block and the driving block continue to abut against each other. The upper blade is fixedly arranged at one end of the driven block, so that the upper blade remains stable after and after the knife adjustment is completed.

[0016] The following is a further detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0017] like Figures 1 to 2 , which is a schematic diagram of the structure of a shearing machine capable of automatic blade adjustment provided by the present invention. The shearing machine capable of automatic blade adjustment includes a shearing machine body 10 and a blade adjustment assembly 20 disposed on the shearing machine body 10. The shearing machine capable of automatic blade adjustment also includes other functional modules, such as a controller and a power distribution device disposed on the shearing machine body. These are well known to those skilled in the art and will not be described in detail here.

[0018] The shearing machine body 10 includes a housing 11, an upper blade assembly 12 disposed in the housing 11, a lower blade assembly 13 disposed in the housing 11, and a drive assembly 14 disposed in the housing 11 and used to drive the upper blade assembly 11 and the lower blade assembly 12 to rotate.

[0019] The housing 11 is a rectangular cabinet-like structure with openings on two opposite sides, serving as the feed and processing ports for the cut material. The housing 11 can be constructed from multiple plates and made of cast iron, alloy, or other rigid materials, serving as the product's housing and protecting the internal structure.

[0020] The upper blade assembly 12 includes an upper blade shaft 121 and an upper blade 122 disposed on the upper blade shaft 121. The lower blade assembly 13 includes a lower blade shaft 131 and a lower blade 132 disposed on the lower blade shaft 131. The upper blade shaft 121 and the lower blade shaft 131 are respectively rotatably disposed within the housing 11, with their axes oriented perpendicularly to the two openings of the housing 11 to facilitate cutting of materials entering the device. The upper blade shaft 121 and the lower blade shaft 131 are both driven by the drive assembly 14 to rotate about their axes, thereby driving the upper blade 122 and the lower blade 132 to rotate about their axes, respectively. By adjusting the rotational positions of the upper blade shaft 121 and the lower blade shaft 131 and the positions of the blades, the upper blade 122 and the lower blade 132 can meet between the upper blade shaft 121 and the lower blade shaft 131 during each rotation, thereby cutting the strip of material located between the upper blade 122 and the lower blade 132. The installation method and principles of the upper blade shaft 121, the lower blade shaft 131, the upper blade 122, and the lower blade 132 are conventional technology, i.e., technology of rotary shearing machines, and are well known to those skilled in the art and will not be further described here.

[0021] The drive assembly 14 is a servo motor, and the drive assembly 14 is disposed on one side of the housing 11. The drive assembly 14 is respectively connected to the upper blade rotating shaft 121 and the lower blade rotating shaft 131, so that the rotation of the upper blade rotating shaft 121 and the lower blade rotating shaft 131 can be simultaneously controlled by the drive assembly 14. The transmission method between the drive assembly 14 and the upper blade rotating shaft 121 and the lower blade rotating shaft 131 is a pulley transmission or a gear transmission. It should be noted that the transmission structure and control method of the drive assembly 14 for controlling the rotation of the upper blade rotating shaft 121 and the lower blade rotating shaft 131 are well known to those skilled in the art and will not be described in detail here.

[0022] The knife adjusting assembly 20 is mounted on the upper blade rotating shaft 121. The knife adjusting assembly 20 includes two mounting plates 21 spaced apart on the housing 11, a main guide rod 22 horizontally disposed between the two mounting plates 21, a slave guide rod 23 spaced apart and parallel to the main guide rod 22, a driving block 24 slidably disposed on the main guide rod 22, a slave block 25 slidably disposed on the slave guide rod 23, and a spring 26 sleeved on the outside of the slave guide rod 23 and located at the end of the slave block 25 facing away from the linear servo motor 242.

[0023] The mounting plate 21 is fixedly mounted on the upper blade shaft 121. The main rod 22 is arranged perpendicular to the mounting plate 21. The driving block 24 is slidably mounted on the outside of the main rod 22. A linear servo motor 242 is provided on one side of the driving block 24. The linear servo motor 242 is fixed on the mounting plate 21, connected to and drives the driving block 24 to move along the main rod 22. An upper inclined surface 241 is provided on the side of the driving block 24 close to the driven block 25. The upper inclined surface 241 is lifted along the pushing direction of the linear servo motor 242, so that the angle between the direction of the upper inclined surface 241 and the extension direction of the driving end of the linear servo motor 242 is an acute angle. The driving block 24 is symmetrical along the vertical plane where the axis of the main rod 22 is located.

[0024] The slave guide rod 23 is disposed perpendicular to the mounting plate 21. One end of the driven block 25 is fixedly connected to the upper blade 122. The driven block 25 is symmetrical along the vertical plane in which the axis of the slave guide rod 23 lies. The axes of the main guide rod 22 and the slave guide rod 23 lie in the same vertical plane. A lower inclined surface 251 is provided on the side of the driven block 25 near the driving block 24. The upper inclined surface 241 and the lower inclined surface 251 have the same angle with the horizontal plane. The top of the upper inclined surface 241 is not lower than the top of the lower inclined surface 251, and the bottom of the upper inclined surface 241 is not higher than the bottom of the lower inclined surface 251. Therefore, when the driving block 24 moves to abut against the driven block 25, the upper inclined surface 241 and the lower inclined surface 251 abut against each other, and the lower inclined surface 251 is contained in the upper inclined surface 241, thereby ensuring the driving effect of the driving block 24. The width of the upper inclined surface 241 is not less than the width of the lower inclined surface 251.

[0025] One end of the spring 26 abuts the driven block 25. When the driven block 25 moves, it compresses the spring 26. When the driving block 24 is controlled to retract, the driven block 25 returns to its original position under the action of the spring 26. The spring 26, along with the upper and lower inclined surfaces 241, 242, enhance the stability of the upper blade 122 after adjustment.

[0026] During use, the operator inputs the distance the upper blade 122 needs to deviate, and the controller controls the linear servo motor 242 to drive the drive block 24 to move along the main rod 22. As the drive block 24 moves, the upper inclined surface 241 abuts the lower inclined surface 252, and after abutment, pushes the driven block 25 to move, thereby driving the upper blade 122 located on the driven block 25 to move, achieving the effect of adjusting the upper blade 122. Because a spring 26 is provided between the driven block 25 and the mounting plate 21, when the drive block 24 retracts due to the contraction of the driving end of the linear servo motor 242, the driven block 25 will return to its original position under the elastic force of the spring 26, thereby causing the driven block 25 to continue to abut against the drive block 24 until it returns to its original position. The driven block 25 is set in the original position at the position where the upper blade 122 is aligned with the lower blade 132, so that the operator can easily inspect the blade adjustment assembly 20 and also can easily adjust the blade after installing the upper blade 122.

[0027] It should be noted that controlling the linear servo motor 242 to move a specified value through a controller is a technical content well known to those skilled in the art, and the connection structure between the controller and the linear servo motor 242 is also a technical content well known to those skilled in the art, which will not be repeated here.

[0028] Compared with the prior art, the shearing machine capable of automatic knife adjustment provided by the present invention realizes automatic knife adjustment by providing a knife adjustment component 20. Specifically, the knife adjustment component 20 includes a driving block 24 slidably sleeved on the outside of the main rod 22, a driven block 25 slidably sleeved on the outside of the slave guide rod 23, two springs 26 sleeved on the outside of the slave guide rod 23 and respectively located on both sides of the driven block 25, and a linear servo motor 242 provided on one side of the driving block 24 and used for driving the driving block 24 to slide along the axial direction of the main rod 22, an upper inclined surface 241 is provided on the side of the driving block 24 facing the driven block 25, and a lower inclined surface 251 is provided on the side of the driven block 25 facing the driving block 24, and the upper inclined surface 241 and the lower inclined surface 251 are aligned with the horizontal plane. The angles between them are the same. During the controlled movement of the driving block 24, the upper inclined surface 241 and the lower inclined surface 251 are abutted and the driven block 25 moves synchronously with the driving block 24. The two springs 26 are respectively squeezed and stretched to drive the driven block 24 to return when the driving block 24 retreats, so that the driven block 24 and the driving block 24 continue to abut. The upper blade 122 is fixedly arranged at one end of the driven block 24, so that the upper blade 122 remains stable after and after the knife adjustment is completed. The accuracy of the knife adjustment is the same as the control accuracy of the linear servo motor 242, so that the accuracy of the knife adjustment can be guaranteed. The driving block 24 is driven by the linear servo motor 242, and then the driven block 25 is driven to move, thereby realizing automatic knife adjustment and improving the speed and efficiency of knife adjustment.

Any modifications, equivalent replacements or improvements within the spirit of the present invention are included in the scope of the claims of the present invention.
