Embodiment Construction

[0020] Examples of steel cutting device Figure 1~4 Shown: Including the frame and the fixed knife 2 and the movable knife 7 which are arranged in a front-to-back displacement. The frame includes a mounting base plate 6 whose thickness extends in the front-to-rear direction. The fixed knife 2 is fixed to the rear side of the mounting base plate by bolts. On the left side of the fixed knife, the base plate is fixedly provided with a left stopper 1 which cooperates with the left end of the fixed knife. The mounting substrate is also provided with a driving device that drives the movable knife to reciprocate in the left and right directions. On the lower side of the movable knife, there are mounting holes 12 that penetrate the front and rear surfaces of the mounting substrate. The driving device is a linear motor. The guide rail 10 includes a guide rail 10 fixed in the mounting hole and extending in the left-right direction. A mover 9 is mounted on the guide rail for guiding movem...

Abstract

The invention relates to a steel bar shearing device which comprises a moving cutter and a machine frame. A driving device for driving the moving cutter to perform reciprocating motion in the left-right direction is arranged on the machine frame and comprises a linear motor, wherein the linear motor comprises guide rails with the guiding direction extending in the left-right direction and an active cell movably assembled on the guide rails in a guiding mode, a transmission lever with the hinge axis extending in the front-back direction is hinged to the machine frame, the active cell is in transmission connection with a power arm of the transmission lever, and the moving cutter is in transmission connection with a resisting arm of the transmission lever. The problem that the manufacture cost of the steel bar shearing device in the prior art is high due to a crankshaft is solved.

Description

Technical field [0001] The invention relates to the field of mechanical processing, in particular to a steel bar cutting device for steel bar cutting. Background technique [0002] Rebar cutting devices need to be used to cut steel bars during on-site construction on construction sites. Existing steel bar cutting devices such as "a steel bar cutting machine" disclosed in Chinese patent CN203155899U, the steel bar cutting machine includes a frame, the frame is provided with a drive device and the fixed knife and movable knife arranged in a forward and backward displacement, on the frame A gap is provided for the steel bars to be placed from top to bottom. The fixed knife is set on the frame on the left side of the gap, the drive device is arranged on the frame on the right side of the gap, and the power output end of the drive device is connected to the movable knife to drive The movable knife moves toward and away from the fixed knife in the left and right direction. The driving...
