Description
Technical field:
The utility model relates to a kind of control device of friction press, the particularly a kind of device that can realize the work of automatic control control friction press.
Background technology:
The friction press that generally uses exists labour intensity big at present, poor safety performance, shortcomings such as quality of item instability.
The structure of existing friction press is referring to Fig. 1, die head 1 and lower die head 2 fixed-type moulds on the friction press, and moulding material fills in the lower die head mould 3.During friction press work, motor 4 founds wheel 5 as the flying wheel store kinetic energy by upright wheel 5 rotations of belt drives.Flat wheel 6 is connected with last die head 1 by screw mandrel 7, and is fixed on the frame 9 by nut 8 by screw mandrel 7; Cylinder 10 drives upright wheel 5 move left and right, make flat wheel 6 can be respectively with about upright wheel 5 produce friction, thereby 6 rotations of flat wheel drive screw mandrels 7 and last die head 1 moves up and down.Because the inertia of upright wheel 5 and the translational speed of last die head 1 produce impulsive force when die head 1 is contacted with lower die head 2, moulding material is hit.Impulsive force is relevant with the inertia that the translational speed of last die head 1 reaches upright wheel 5 and last die head 1.The impulsive force that different moulding materials needs is also different with cycle.Shaped article after the punching press is in lower die head 2.It is up to drive ejector beam 11 when last die head is up simultaneously, when arriving certain altitude shaped article is ejected from lower die head 2, is called liftout.
The control mode of above-mentioned friction press is the pneumatic control mode, and adopts the manual mode of operation, by 3 operator's operations: loaders, get material worker and board worker.The board worker is by the whole forming process of manual Air Valve Control.Operating process is as follows:
(1) die head comes downwards to packed height on the board industry control system;
(2) loaders' filler;
(3) the board worker requires control to go up die head according to hitting power to go upward to and hit height, then control down fraction time hit; Repeat to hit, up to the cycle of finishing regulation;
(4) die head is up on the board industry control system ejects from lower die head up to finished bricks;
(5) getting the material worker takes out finished bricks; And circulation above-mentioned steps.
Existing friction press adopts above-mentioned artificial pneumatic mode of operation, all has deficiency and problem at aspects such as product quality, board efficient and personal safeties:
(A) product quality problem: by actuating friction forcing press operated pneumatic valve, the size of frictional force realizes pressure between the flat wheel of control, the upright wheel, reaches adobe density.Present pressure brick action is the gas control manually-operated, because workman's technical merit is different, only only by rule of thumb the friction press operated pneumatic valve is operated by certain flow process, control accuracy is poor, hitting power is inconsistent, the product quality of producing obviously has fluctuation, and this also is the greatest drawback of this equipment.
(B) board efficient is low: it is the gas control manually-operated that flow processs actions such as brick strike, liftout and playback are pressed in present friction, and because of human factor, it is not in place to produce control, influences production efficiency.
(C) personal safety problem: get to know on the friction press-distance of descending to get to know is about 700mm.During the machine brick output, be now artificial handle reach get to know-take brick in the middle of descending to get to know, because of no safety guard, in case maloperation just personal injury may occur, personal safety can not get assurance, and is abnormally dangerous.
The utility model content:
The utility model is big at the labour intensity of the friction press existence of above-mentioned present use; poor safety performance; defectives such as quality of item instability can realize hand/half/Automatic Control, local and long-range strike control, slide block logic control and automatic homing operates and the control device of functions such as liftout operation, safeguard protection, running state monitoring and provide a kind of.
