Description

Technical Field

[0001] This application relates to the field of sheet metal forming and shearing technology, and in particular to a rotary shearing device. Background Technology

[0002] Currently, roll forming equipment is needed to cold-press certain sheets to process them into the required cross-sectional shapes. After the sheets are formed, shearing equipment is required to cut them to a fixed length.

[0003] The existing Chinese patent with publication number CN215238128U discloses a hydraulic forming and shearing device for roof tiles with auxiliary rollers. Its structure is that the base is connected to the gantry frame through the column. The top surface of the gantry frame is equipped with a hydraulic cylinder. The output end of the hydraulic cylinder passes downward through the gantry frame and is connected to the top of the upper cutter holder through the connecting block. The two sides of the upper cutter holder are slidably connected to the guide lubrication grooves set on the inner side of the column. The upper cutter holder is equipped with an upper blade. Below the upper blade is a contouring lower blade. The contouring lower blade is installed on the top surface of the base through a side plate. The side plate has a contouring outlet. An auxiliary roller is located below the outer side of the contouring outlet. The contouring lower blade includes a main arched part located in the center, two W-shaped parts on both sides of the main arched part, and first and second side arched parts located on the outer sides of the two W-shaped parts respectively. The distance between the two sides of the first side arched part is greater than the distance between the two sides of the second side arched part.

[0004] Regarding the aforementioned technologies, the gantry frame is fixed to the base, and the upper blade works in conjunction with the lower blade to cut the roof tiles. However, during the cutting process, the blades cut along a direction perpendicular to the length of the roof tiles, meaning the cut end face of the roof tiles is perpendicular to its own length. This makes it difficult to perform bevel cuts on some materials, resulting in poor applicability. Utility Model Content

[0005] To facilitate adjustment of the angle of the shearing end face of the sheet metal and improve its applicability, this application provides a rotary shearing device.

[0006] The rotary shearing device provided in this application adopts the following technical solution:

[0007] A rotary shearing device includes a base, a mounting frame, an upper blade, and a lower blade. The upper blade is slidably mounted on the mounting frame along the height direction, and the lower blade is fixedly mounted on the mounting frame. The upper blade and the lower blade are installed with their heights offset. The mounting frame is rotatably connected to the base. The mounting frame is rotatably and adjustablely connected to the base via a vertical connecting shaft. The base is provided with a driving component for driving the mounting frame to rotate.

[0008] By adopting the above technical solution, when it is necessary to bevel the sheet metal, the mounting bracket can be rotated by the drive component, which can simultaneously drive the upper and lower blades to adjust their angles. Since the sheet metal is generally conveyed along a horizontal plane, the angle of the sheared end face of the sheet metal can be adjusted when the shearing angle of the upper and lower blades changes while the conveying direction of the sheet metal remains unchanged.

[0009] Preferably, the connecting shaft is located at the midpoint between the cutting lines of the upper blade and the lower blade.

[0010] By adopting the above technical solution, the connecting shaft can drive the upper and lower blades to rotate along the vertical center position of the cutting line. Therefore, when the connecting frame, the upper blade and the lower blade rotate synchronously, the cutting line formed by the upper blade and the lower blade can better adapt to the cross section of the plate.

[0011] Preferably, the lower end of the mounting bracket is provided with a plurality of support wheels, and the support wheels are in support contact with the base.

[0012] By adopting the above technical solution, the support wheel can support the mounting frame and make the rotation between the mounting frame and the base smoother.

[0013] Preferably, a plurality of pads are horizontally arranged on the base, and the lower end of the support wheel is supported on the pads.

[0014] By adopting the above technical solution, the support wheel can roll along the surface of the pad because it needs to bear a certain weight.

[0015] Preferably, the driving component is an electric cylinder, the telescopic rod of the electric cylinder is rotatably connected to the mounting bracket, the cylinder body of the electric cylinder is rotatably connected to the base, and the rotation axes of the telescopic rod and the cylinder body are both vertically arranged.

[0016] By adopting the above technical solution, when the telescopic rod of the electric cylinder moves in extension and retraction, it can drive the mounting frame to achieve rotational adjustment.

[0017] Preferably, the mounting frame includes a mounting block and a gantry frame. The mounting block is rotatably connected to the base. The two ends of the opening of the gantry frame are fixed to the mounting block. An upper blade holder is slidably connected inside the opening of the gantry frame along the height direction. The upper blade is mounted on the upper blade holder, and the lower blade is mounted on the mounting block.

[0018] By adopting the above technical solution, the upper blade can slide up and down the mounting bracket.

[0019] Preferably, the gantry frame includes a top block and two guide rods. The upper ends of the two guide rods are vertically fixed to both ends of the top block. The top block and the mounting block are arranged opposite each other vertically. The lower ends of the guide rods are fixed to both ends of the mounting block.

[0020] By adopting the above technical solution, the connection between the gantry and the base can be realized, so as to facilitate the installation of the upper and lower blades.

[0021] Preferably, the mounting bracket further includes a reinforcing rod, one end of which is connected to the top block, and the other end of which is connected to the mounting block.

[0022] By adopting the above technical solution, the two ends of the support rod are fixed to the top block and the mounting block respectively, which can improve the structural stability of the mounting frame.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] (1) By setting the cooperation between the base, mounting bracket, connecting shaft and drive component, the cutting position of the upper blade and the lower blade can be adjusted, thereby realizing the angle adjustment of the shearing end face of the plate;

[0025] (2) By setting support wheels, the mounting frame and the components on the mounting frame with a certain weight can be supported, while ensuring smooth rotation between the mounting frame and the base.

[0026] (3) The connecting shaft is set vertically and located in the middle of the cutting lines of the upper and lower blades to ensure that the upper and lower blades can still cut the plate normally when the mounting bracket is rotating. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0031] This application discloses a rotary shearing device. (Refer to...) Figure 1 and Figure 2The rotary shearing device includes a base 1, a mounting bracket 2, an upper blade 3, and a lower blade 4. In this embodiment, the sheared sheet metal is conveyed horizontally. The mounting bracket 2 is rotatably connected to the base 1, and the mounting bracket 2 is rotatably adjustable to the base 1 via a connecting shaft 5. The connecting shaft 5 is vertically arranged, and the base 1 is provided with a driving component 6 for driving the mounting bracket 2 to rotate and adjust.

[0032] The upper blade 3 is slidably mounted on the mounting frame 2 along the height direction, and the lower blade 4 is fixedly mounted on the mounting frame 2. Both the upper blade 3 and the lower blade 4 are horizontally set, and the upper blade 3 and the lower blade 4 are installed in a staggered manner. The mounting frame 2 is equipped with a hydraulic cylinder for driving the upper blade 3 to move up and down. When the upper blade 3 moves downward and is staggered with the lower blade 4, it can cut the plate.

[0033] The connecting shaft 5 is located at the midpoint between the cutting lines of the upper blade 3 and the lower blade 4. When the mounting bracket 2 rotates, the upper blade 3 and the lower blade 4 can also rotate horizontally along the center of the cutting line for better cutting of the sheet metal. When the sheet metal conveying direction remains unchanged, but the angle of the cutting line changes, the angle of the sheared end face of the sheet metal can be adjusted.

[0034] The drive component 6 is an electric cylinder. The telescopic rod of the electric cylinder is rotatably connected to one end of the mounting bracket 2, and the tail of the cylinder body is rotatably connected to the base 1. The rotation axes of both the telescopic end of the electric cylinder and the cylinder body are vertically set. When the telescopic rod moves horizontally back and forth, the angle of the mounting bracket 2 can be adjusted. An angle detector is set on the connecting shaft 5 to detect the rotation angle of the connecting shaft 5. The angle detector is connected to the electric cylinder control to more accurately detect the adjustment angle of the mounting bracket 2.

[0035] Mounting frame 2 includes mounting block 21, gantry frame 22, and reinforcing rods 23. Mounting block 21 is rotatably connected to base 1. Gantry frame 22 includes top block 221 and two guide rods 222. The upper ends of the two guide rods 222 are vertically fixed to both ends of top block 221, and the lower ends of guide rods 222 are fixed to both ends of mounting block 21. Top block 221 and mounting block 21 are arranged vertically opposite each other. An upper blade holder 7 is slidably connected along the height direction inside the opening of gantry frame 22. Both ends of upper blade holder 7 are slidably connected to guide rods 222. Upper blade 3 is installed on upper blade holder 7, and lower blade 4 is installed on mounting block 21. Two reinforcing rods 23 are vertically arranged. One end of reinforcing rod 23 is connected to top block 221, and the other end is connected to mounting block 21. Both ends of reinforcing rod 23 are bolted to mounting block 21 and gantry frame 22 to improve the structural stability of mounting frame 2.

[0036] Several support wheels 8 are fixed to the lower end of the mounting block 21. The support wheels 8 are in contact with the base 1. In this embodiment, three support wheels 8 are provided, located near both ends and the middle of the mounting block 21, respectively. The support wheels 8 can be used to support the mounting frame 2 and other components on the mounting frame 2. At the same time, they ensure smooth rotation between the mounting frame 2 and the base 1.

[0037] In some embodiments, a plurality of pads 9 are horizontally welded onto the base 1. The pads 9 are made of metal sheet, and the lower ends of the support wheels 8 are supported on the pads 9.

[0038] The implementation principle of the rotary shearing device in this application embodiment is as follows: When the mounting frame 2 is in the initial position, the cutting lines of the upper blade 3 and the lower blade 4 are perpendicular to the conveying direction of the plate, thus enabling traditional vertical end-face shearing of the plate. When the end face of the plate needs to be beveled, the mounting frame 2 can be rotated by the driving component 6, thereby adjusting the cutting line angle of the upper blade 3 and the lower blade 4. Therefore, when the conveying direction of the plate remains unchanged, the angle of the end face being sheared also changes accordingly, achieving the effect of easily adjusting the angle of the sheared end face of the plate and improving its applicability.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
