The following specific embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
The specific embodiment
Please refer to Fig. 1 and Fig. 2, shearing jig 100 comprises a base plate 1, be arranged at the guide rail 2 on base plate 1, slip is arranged at the load plate 3 on guide rail 2, protrude from three positioned parallel bars 4 on base plate 1, be fixed on the first gripper shoe 5 on backstay 4 ends, be arranged at two first long-range cylinders 6 of the first gripper shoe 5 belows, be fixed on the second gripper shoe 7 on two first long-range cylinder 6 piston rods, be arranged at the second long-range cylinder 8 in the second gripper shoe 7, be arranged at the cutting knife 9 on the second long-range cylinder 8 piston rods, the first switching device 10, the first interlock 11, second switch device 12 and the second interlock 13, wherein load plate 3 is for place work piece 16.This first interlock 11 is arranged on base plate 1 and one end of close guide rail 2, and the second interlock 13 is arranged at the below of the second gripper shoe 7.The first long-range cylinder 6 and the second long-range cylinder 8 comprise respectively a piston, are positioned at top cavity and the below cavity of piston both sides and are fixedly attached to the piston rod on piston.
With reference to figure 3, the first switching device 10 is three mouthfuls of two-position valves, and it comprises A1 valve port, B1 valve port and P1 valve port, and wherein A1 valve port is connected with the below cavity of two first long-range cylinders 6, B1 valve port is connected with the first interlock 11, and P1 valve port is connected with the first air pressure or hydraulic means 14.In the time not pressing the first switching device 10, P1 valve port is communicated with A1 valve port, and then the piston rod that can act on the first long-range cylinder 6 drives the second gripper shoe 7 to move upward; In the time pressing the first switching device 10, P1 valve port is communicated with B1 valve port.
The first interlock 11 comprises A2 valve port, B2 valve port and P2 valve port, and wherein A2 valve port is in communication with the outside, and B2 valve port is communicated with two first long-range cylinder 6 top cavitys, and P2 valve port is connected with the A1 valve port of the first switching device 10.In the time not triggering the first interlock 11, P2 valve port is communicated with A2 valve port; In the time triggering the first interlock 11, P2 valve port is communicated with B2 valve port.
The second interlock 13 comprises A4 valve port, B4 valve port and P4 valve port, and wherein A4 valve port is in communication with the outside, and B4 valve port is communicated with the top cavity of the second long-range cylinder 8, and P4 valve port is connected with the B3 valve port of second switch device 12.In the time not triggering the second interlock 13, P4 valve port is communicated with A4 valve port; In the time triggering the second interlock 13, P4 valve port is communicated with B4 valve port.
When use, just load plate 3, from cutting knife 9 below pull-outs, after place work piece 16 is pushed into load plate 3 cutting knife 9 belows and triggers the first interlock 11.Now press the first switching device 10, the working media (liquid or gas) that the first air pressure or hydraulic means 14 provide enters the top cavity of two first long-range cylinders 6 through P1 valve port, B1 valve port, P2 valve port and B2 valve port, and then drives its piston rod to drive the second gripper shoe 7 to move downward and trigger the second interlock 13.Continue to press second switch device 12, the working media that the second air pressure or hydraulic means 15 provide is through the top cavity of P3 valve port, B3 valve port, P4 valve port and B4 valve port and then the second long-range cylinder 8, and then drives its piston rod to drive cutting knife 9 to move downward and shear the workpiece 16 being arranged on load plate 3.User can press respectively the first switching device 10 and second switch device 12 by both hands simultaneously, therefore can avoid cutting knife 9 to move downward and hurt user.
After having sheared, unclamp the first switching device 10 and second switch device 12, the working media that the first air pressure or hydraulic means 14 provide enters the below cavity of two first long-range cylinders 6 through P1 valve port and A1 valve port, and then the piston rod of effect the first long-range cylinder 6 drives the second gripper shoe 7 to move upward, the working media P3 valve port that the second air pressure or hydraulic means 15 provide and A3 valve port enter the below cavity of two second long-range cylinders 8, and then the piston rod of effect the second long-range cylinder 8 drives cutting knife 9 to move upward, therefore can conveniently pull out load plate 3 and take out the workpiece 16 on it.
In the middle of another embodiment, described shearing jig 100 comprises the first long-range cylinder 6, the first switching device 10, the first interlock 11 and the first air pressure or hydraulic means 14, and do not comprise the second gripper shoe 7, the second long-range cylinder 8, second switch device 12, the second interlock 13 and the second air pressure or hydraulic means 15, cutting knife 9 is arranged on the first long-range cylinder 6.In the time that load plate 3 triggers the first interlock 11 along guide rail movement, the piston rod of pressing the first switching device 10, the first long-range cylinders 6 drives cutting knife 9 to move downward and shears workpiece 16.
In the time that load plate 3 does not move to the position of triggering the first interlock 11, when pressing the first switching device 10 and second switch device 12, the working media that the first air pressure or hydraulic means 14 provide is gone out through P1 valve port, B1 valve port, P2 valve port and A2 valve port, and the piston rod that therefore cannot act on two first long-range cylinders 6 drives the second gripper shoe 7 to move downward and triggers the second interlock 13.The working media of the second air pressure or hydraulic means 15 is gone out through P3 valve port, B3 valve port, P4 valve port and A4 valve port, the piston rod that therefore can not act on the second long-range cylinder 8 drives cutting knife 9 to move downward, and therefore can effectively keep away while pressing the first switching device 10 and second switch device 12 by mistake and cause cutting knife 9 to move downward.
Although the preferred embodiment of the present invention is illustrated and is described, those skilled in the art will realize, and can make various changes and improvements, and these do not exceed true scope of the present invention.Therefore expect, the present invention is not limited to disclosed conduct and realizes the specific embodiment of the contemplated optimal mode of the present invention, and all embodiments that the present invention includes have in the protection domain of appended claims.
