Description
Affiliated technical field
The utility model belongs to a kind of rubber cutting machine that is used to cut rubber washer
Background technology
The rubber cutting machine primary structure of existing processing rubber packing ring is: the main shaft that is in transmission connection with drive motors is set on workbench, the workpiece mandrel that workpiece blank is installed is contained between main shaft and the tail tip seat, the knife rest of processing work is connected with screw drive, can drive knife rest radially advance and retreat cutter cam link mechanism and can drive toggle and the cutter motor that screw rod intermittently rotates and be in transmission connection, referring to Fig. 4, wherein be applied in the cam link mechanism in the connecting rod (22) of cam (20) back-moving spring (29) is housed, connecting rod can automatically reset after the displacement under cam (20) effect, thereby driving the knife bar that adds on the knife rest radially advances, withdrawing, the screw rod that intermittently rotates under the toggle effect then drives tool axis to the stepping at intermittence.The weak point of this device is: because the spring force size can not be adjusted, and contractility is inhomogeneous, so cause radially forward and back cutter unbalance stress of the knife bar that driven by the cam link mechanism connecting rod, and the amount of force between knife bar and the workpiece can not adjust, blade abrasion is fast.In addition the every axially stepping of the rubber cutting machine knife rest of this structure once, knife bar radially feed cuts a subjob, promptly a kind of stepping length can only be cut a kind of rubber washer of width.
Summary of the invention
The technical problems to be solved in the utility model provides that the stressed size of a kind of knife bar can be adjusted, the cutter of advancing and retreat is stressed evenly, and can adjust the per twice axial rubber cutting machine of stepping number of times in the feed at interval radially of knife rest.
The technical scheme that addresses the above problem is (referring to implementing illustration): the utility model is provided with the main shaft (7) that is in transmission connection with drive motors (10) on workbench, workpiece mandrel (12) is contained between main shaft and the tail tip seat (14), also be provided with the cam link mechanism (3) and the toggle (1) that are in transmission connection with cutter motor (4), knife rest (11) is in transmission connection with screw rod (6), screw rod (6) with can drive its toggle that intermittently rotates (1) and be in transmission connection, knife bar on the knife rest (13) with can drive it and radially advance, the cam link mechanism of withdrawing (3) is in transmission connection, it is characterized in that: the connecting rod (22) and reset cylinder (24) driving coupling that can be shifted under cam (20) effect in the described cam link mechanism, reset cylinder connects source of the gas (37) by solenoid directional control valve (34).
The technical scheme that is equal to foregoing is to replace pneumatic circuit with hydraulic circuit.
The course of work of the present utility model is: drive motors drives main shaft (7) and workpiece mandrel (12) rotates, cutter motor (4) drives cam link mechanism (3) and toggle (1) rotates, toggle drives screw rod (6) and intermittently rotates, make intermittently axially stepping of knife rest (11), cam in the cam link mechanism (20) acts on connecting rod (22), knife bar (13) on the drive knife rest is withdrawing radially, connecting rod (22) is after displacement under the cam effect, under cylinder (24) effect, reset again, drive radially feed of knife bar, during each withdrawing, tool axis is to stepping, the cutting width of stepping length decision rubber washer, because the expanding-contracting action of cylinder can pass through solenoid control, after so this practical connecting rod (22) is shifted by the cam effect, can control cylinder (24) intermittently moving drivening rod (22) after the stepping repeatedly again at knife rest resets, make knife bar finish next time radially feed, that is to say and make tool axis repeatedly to stepping, radially feed is once for knife bar, adjust the cutting width (and prior art back-moving spring flexible is difficult to circuit control, so can't realize this function) of rubber washer with this.
The utility model has replaced the spring of prior art with cylinder in cam link mechanism, the contractility of cylinder is evenly adjustable, thereby can make knife bar stressed evenly, and can adjust the stressed size of knife bar according to the workpiece situation, reduces the wearing and tearing of blade.Simultaneously owing to the action of stretching, contract of cylinder can be controlled by solenoid valve control circuit, so tool axis is after stepping, whether radially the knife bar action of feed also is controlled, thereby can make the every axially stepping of knife rest once, behind secondary or the several times, radially feed is once for knife bar, that is to say by adjusting per twice width of the stepping number of times adjustment between feed cutting rubber ring radially, make a kind of knife rest of stepping length can cut the rubber washer of multiple width.
