Description
Technical field
The utility model relates to bar cropper technical field more particularly to a kind of anti-ejection bar croppers.
Background technique
Reinforcing bar is usually taken as the skeleton of cement components in project building construction, but due to the specification of cement components
It is different, therefore usually need to cut off the longer reinforcing bar of one ruler cun, cutting off used tool is bar cropper.
The existing notification number that can refer to is CN204912615U, and the day for announcing is the Chinese patent of 2015.12.30, disclosure
A kind of bar cropper, including the first transmission shaft that cutting machine actuating device drives, the first transmission shaft passes through gear and second
Transmission shaft cooperative movement is equipped with flying wheel on the first transmission shaft, and flying wheel is provided centrally with mounting hole, passes through spline and first
Propeller shaft couplings, so that bar cropper has the advantages that run smoothly.
Prior art among the above, which has the following deficiencies:, can generate very big impact when cut-off due to reinforcing bar
Power, therefore cut-off reinforcing bar is easy to launch under the action of this strand of impact force, to endanger the injury of operator.
Utility model content
The purpose of this utility model is to provide one kind to prevent reinforcing bar from ejection occurring when cut-off to improve operation peace
Full bar cropper.
The technical purpose of the utility model has the technical scheme that
A kind of anti-ejection bar cropper, including body offer cut-off port on body, cutting are fixedly installed on body
Component, cutting assembly include cutting off cylinder and the dynamic cutter affixed with the telescopic rod of cutting cylinder, and dynamic cutter is located at cut-off port
At position, dynamic cutter is provided opposite to the quiet cutter affixed with body, and dynamic cutter, quiet cutter are respectively positioned on the marginal position of cut-off port
Place is fixedly installed quiet ballistic resistant sheet on the quiet cutter, is fixedly connected with dynamic ballistic resistant sheet on dynamic cutter, moves ballistic resistant sheet and quiet shellproof
Piece is facing each other.
Through the above technical solutions, cutting cylinder drives dynamic cutter translation, dynamic to cut by reinforcing bar to be cut off by cut-off port
Knife completes cutting operation during constantly close to quiet cutter.During the translation of dynamic cutter, dynamic cutter will drive dynamic anti-
Elastic slice moves together, so that dynamic ballistic resistant sheet starts to be cut until reinforcing bar is completely severed constantly close to quiet ballistic resistant sheet in reinforcing bar
During, cutter can generate biggish impact force to reinforcing bar, especially be completely severed in a flash in reinforcing bar, impact force reaches
To maximum value, at this point, dynamic ballistic resistant sheet and quiet ballistic resistant sheet are close to each other, the reinforcing bar of cutting is blocked in centre, therefore can be effective
It prevents reinforcing bar from launching, improves the safety of operation.
