The beneficial effects of this embodiment lie in: the wave arc-shaped punching shear head is matched with the wave arc-shaped punching shear groove on the punching shear platform, and the piston rod drives the punching shear head to punch and shear the adjusting gasket once under the drive of the hydraulic cylinder, so that the wave arc-shaped structure can be obtained, the machining process of the wave arc-shaped structure is realized, the wave arc-shaped structure is cut by adopting a conventional tool, chamfering machining is firstly carried out, and then the arc shape is cut.
Further, the hydraulic cylinder penetrates through the mounting platform, a mounting bolt is arranged on the mounting platform, and the hydraulic cylinder is reversely mounted at the bottom of the mounting platform by the aid of the mounting bolt. When the punching shear bit punches the shear, produce the reaction force and can act on mounting platform, its mounting bolt does not receive the reaction force, consequently the mounting bolt installs in mounting platform's bottom and compares in the top of installing at mounting platform, and it can avoid the reaction force, extension mounting bolt's life.
Further, the edge of the punching shear groove is matched with the blade profile of the punching shear head. The edge of the punching shear groove is matched with the blade outline of the punching shear tool bit, namely, the edge of the punching shear groove is consistent with the outline of the adjusting gasket after being processed, so that the punching shear platform can well support the adjusting gasket in the punching shear process, the wavy arc side edge of the adjusting gasket after punching shear is more neat, and the adjusting gasket cannot deform in the punching shear process.
Further, the thickness of the punching shear head is 6-10cm.
Further, the joint of the mounting platform and the machine base is provided with a reinforcing rib.
Further, the mass of the stand is greater than three times the mass of the mounting platform.

Detailed Description
The following is a further detailed description of the embodiments:
reference numerals in the drawings of the specification include: the device comprises an adjusting gasket 1, a punching and shearing platform 2, a punching and shearing groove 21, a machine base 3, reinforcing ribs 31, a mounting platform 4, mounting bolts 41, a mounting gasket 42, a hydraulic cylinder 5, a hydraulic cylinder piston rod 6, a punching and shearing tool bit 7 and a cutting edge 71.
Examples are shown in fig. 2 to 4: the utility model provides a processing wave curved cuts utensil to the direction of figure 3 is description direction, including punching shear platform 2, the right side of punching shear platform 2 to punching shear platform center between the welding have frame 3, the top surface has the mounting platform 4 with frame 3 integrated into one piece processing on the frame 3 mounting platform 4 is connected out with frame 3 and is equipped with strengthening rib 31, and the quality of frame 3 is the quadruple of mounting platform 4 quality for mounting platform 4 is in on frame 3 with the focus of frame 3, and the biasing punching shear platform 2, and holistic focus is low like this, and strengthening rib 31 can support mounting platform 4, increases overall structure's intensity, therefore cuts the utensil more stable when the operation.
With the direction of fig. 3 as the description direction, be provided with the mesopore that can hold pneumatic cylinder 5 between the left side edge of mounting platform 4 and the center of mounting platform 4, mesopore radius size is unanimous with pneumatic cylinder 5, the bottom of pneumatic cylinder 5 passes the mesopore, use mounting bolt 41 and mounting pad 42 to install on the mounting platform bottom, i.e. pneumatic cylinder 5 and mounting platform 4 threaded connection, install mounting bolt 41 in the bottom of mounting platform 4 like this, when pneumatic cylinder 5 during operation, the reaction force that the pneumatic cylinder received can act on mounting platform, and do not produce effort to mounting bolt 41, the life of mounting bolt 41 has been prolonged.
A hydraulic cylinder piston rod 6 integrated with the hydraulic cylinder 5 is connected with the bottom of the hydraulic cylinder 5, an installation chuck is welded on the hydraulic cylinder piston rod 6, the installation joint is detachably connected with a punching shear tool bit 7, so that the tool bit can be replaced when different workpieces are punched,
the thickness of the punching shear head 7 is 10cm, the concave outline of the cutting edge 71 of the punching shear head 7 is consistent with the convex edge of the adjusting gasket 1, so the cutting edge 71 of the punching shear head 7 can be in seamless clamping with the side edge of the adjusting gasket.
