Description

Technical Field

[0001] The utility model relates to the technical field of ship production, in particular to a plate shearing device used for ship production. Background Art

[0002] Ships are a general term for various vessels. They are vehicles that can navigate or anchor in water for transportation or operations. They possess varying technical performance, equipment, and structural types depending on their intended use. A ship is a man-made vehicle that primarily operates in water. Its interior primarily comprises a container, support structure, and drainage system, with a propulsion system utilizing either external or internal energy sources. Its exterior generally features a streamlined envelope that helps overcome fluid resistance. Materials have evolved with technological advancements, from early natural materials such as wood, bamboo, and hemp to more modern materials such as steel, aluminum, fiberglass, acrylic, and various composite materials, with steel and other metals being the most common.

[0003] During the shipbuilding process, some small plates need to be sheared into different shapes. Shearing equipment is needed to shear the small plates. Since the shearing base plate is in contact with the sheared plate for a long time during the shearing process, the shearing base plate is a wearing part and needs to be replaced in time. However, most of the existing shearing base plates are fixed and difficult to disassemble. Therefore, a shearing equipment for shipbuilding is proposed to solve the above problem. Utility Model Content

[0011] (3) Beneficial effects

[0012] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0013] The utility model provides bolts, washers and nuts, screws the two nuts, and then removes the two washers from the outsides of the two bolts, so that the shear base plate can be removed from the rear end of the shear base.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] In the embodiment, Figure 1 and 2A shearing device for ship production is given, comprising a workbench 1, the top of the workbench 1 is fixedly connected to a bracket 2, the bracket 2 is hinged with a cylinder 3, the inner side of the cylinder 3 is slidably connected to a cylinder push rod 4, the cylinder push rod 4 is hinged with a connecting handle 5, the connecting handle 5 is hinged with a shearing blade 6, the top of the workbench 1 is detachably connected to a shearing base 7, the shearing blade 6 is hinged to the front end of the shearing base 7, the shearing base 7 is detachably connected to a shearing bottom plate 8, the inner side of the shearing base 7 is fixedly connected to a fixed rod 9, the outer side of the fixed rod 9 is slidably connected to a clamping seat 10, the front end of the fixed rod 9 is fixedly connected to a limiting plate 11, and a notch 12 is provided on the shearing bottom plate 8.

[0019] With the above arrangement, the staff first lifts the pressing seat 10 by hand, so that the pressing seat 10 slides upward along the outer side of the fixed rod 9, and places the small plate on the top of the shear base 7 and the shear bottom plate 8, and then gently supports the pressing seat 10 to slowly move down until the pressing seat 10 is pressed on the top of the small plate, and then starts the cylinder 3, the cylinder push rod 4 is pushed out, the cylinder 3 rotates clockwise along the hinge position, the connecting handle 5 drives the shear blade 6 to rotate, and the shear blade 6 rotates clockwise along the hinge position between the shear base 7, and the shear blade 6 contacts the small plate to push the small plate down to contact with the notch 12, and the shear blade 6 is further pushed down until When cutting small plates, it should be noted that the weight of the clamping seat 10 is large, which can ensure that the small plates are pressed down. During the shearing process, the small plates do not move. Since the shearing base plate 8 is a wearing part, it can be disassembled and replaced with a new shearing base plate 8 and installed on the shearing base 7 to ensure that the entire device can work normally. It should also be noted that the shearing blade 6 is hinged to the connecting handle 5 and the shearing base 7 through hinge bolts and hinge nuts. Therefore, when the shearing blade 6 is damaged, the hinge nut can be screwed to remove the shearing blade 6 and replace the new shearing blade 6 to install on the connecting handle 5 and the shearing base 7.

[0020] Reference Figure 1 and 2 , wherein, the front end of the shear plate base 7 is provided with two bolts 13, one end of which penetrates and extends to the rear side of the shear base 8, the outer sides of the two bolts 13 are sleeved with washers 14, the outer sides of the two bolts 13 are threadedly connected with nuts 15, and the front and rear ends of the two washers 14 are in contact with the shear base 8 and the two nuts 15 respectively;

[0021] Through the above-mentioned structural setting, by screwing the two nuts 15 and then removing the two washers 14 from the outside of the two bolts 13, the shear base 8 can be removed from the rear end of the shear base 7. After replacing the new shear base 8 and installing it on the rear end of the shear base 7, the two washers 14 are put back on and the two nuts 15 are screwed again to make the shear base 8 relatively fixed to the shear base 7.
