Abstract

Disclosed is a hydraulic toggle lever transmission brake type plate shearing machine, comprising a machine frame (1) and hydraulic systems (4), wherein three groups of guide rail wheels (7) are arranged between two vertical columns (2) of the machine frame (1), a movable tool rest (3) is connected among the three groups of guide rail wheels (7), a blade is arranged on the movable tool rest (3), the guide rail wheels (7) are all fixedly connected between upper ends or lower ends of the two vertical columns (2), the hydraulic systems (4) are arranged on the outside of the two vertical columns (2), the two vertical columns (2) are connected to the hydraulic systems (4), the hydraulic systems (4) are connected to the movable tool rest (3) via a toggle lever (5), and the toggle lever (5) penetrates the vertical column (2) and can rotate by taking the connection point between itself and the vertical column (2) as a pivot point. By means of the hydraulic toggle lever transmission brake type plate shearing machine, the external height and centre of gravity of the whole machine are lowered, and stability is improved; and the plate shearing machine is rational in structure, and is convenient to adjust, maintain, assemble and disassemble.

IPC Classes  ?

• B23D 15/08 - Sheet shears with a blade moved in one plane, e.g. perpendicular to the surface of the sheet

Abstract

A pull rod screw-down leveler, comprising a pull rod (5), a movable upper beam (10) and a fixed lower beam (2); the movable upper beam is provided with an upper levelling roller (3), and the fixed lower beam is provided with a lower levelling roller (4); the two ends of the movable upper beam are connected to the pull rod, and the fixed lower beam is connected to a pull rod screw-down power mechanism; the pull rod is disposed within a pull rod seat (15) at the two ends of the upper beam, and the bottom of the fixed lower beam corresponding to the pull rod seat is provided with a pull rod power device; and the pull rod is disposed within the pull rod seat and connected to the power device, and the power device causes the pull rod to move relative to the pull rod seat in the axial direction. The leveler eliminates a transverse beam and a longitudinal beam, providing a simplified structure; and the origin of force of the screw-down power device is at the outermost side of the movable upper beam, thus easily controlling the balance of the levelling rollers.

Abstract

A built-in transmission apparatus of a plate shearing machine comprises a pneumatic clutch (1), a flywheel (2), a transmission shaft (3), a wall plate (4), an unloading sleeve (5), a pinion (6), a gear (7) and a shaft (8). The pinion is mounted in the unloading sleeve; the gear and the shaft are mounted in a matching manner; the pinion, the gear, and the shaft together form a transmission structure and are mounted on an inner side of the wall plate; the flywheel and the pneumatic clutch are sequentially mounted on an outer side of the wall plate; the transmission shaft is connected to the transmission structure. The transmission apparatus optimizes a mounting position and load distribution, improves safety performance of the device, and prolongs the service life of the device.

Abstract

An electric system of a lathe-miller combined machine tool with simultaneously copying inner and outer circles of a piston ring comprises an embedded and integrated industrial computer, a programmable logic controller, a first frequency changer, a second frequency changer, and a servo amplifier. The embedded and integrated industrial computer is connected to the programmable logic controller through the RS232 interface, and is connected to the first frequency changer and the second frequency changer separately through the RS485 interface; the programmable logic controller is connected to the servo amplifier through the RS422 interface; and the servo amplifier is connected to a lathe feed motor, the first frequency changer is connected to a spindle motor, and the second frequency changer is connected to a miller feed motor. In this solution, with a network electric control system, device parameters and control information can be synchronously transmitted, displayed, and set in real time. Control buttons of the system are mostly implemented by using a touch screen, thereby simplifying the operation, reducing the cost of hardware system devices, and achieving a desirable use effect.
