Detailed description of the invention
The present invention includes once filling adjusting mechanism, secondary filling adjusting mechanism ..., n filling adjusting mechanism, powder feeding mechanism and die cavity mechanism, described primary filling guiding mechanism comprises primary filling adjustment motor, primary filling adjustment motor connects primary filling adjustment Limit screw by transmission mechanism, and primary filling limited roller is established in primary filling adjustment Limit screw bottom; Described secondary filling adjusting mechanism comprises secondary filling adjustment motor, and secondary filling adjustment motor is by transmission mechanism connecting secondary filling adjustment Limit screw, and secondary filling limited roller is established in secondary filling adjustment Limit screw bottom; Described n filling adjusting mechanism comprises n filling adjustment motor, and n filling adjustment motor connects n filling adjustment Limit screw by transmission mechanism, and n filling limited roller is established in n filling adjustment Limit screw bottom; Described once adjust Limit screw, secondary adjustment Limit screw ..., n time adjustment Limit screw rise successively in lengthwise position; Described die cavity organization establishes is in the bottom of powder feeding mechanism, die cavity mechanism bottom connects reset cylinder by a lifters, reset cylinder top establish successively the lifting of corresponding with each filling adjusting mechanism restriction lifters a demoulding swing arm, secondary demoulding swing arm ..., n-1 demoulding swing arm, each demoulding swing arm all can present locking or movable two states.
The filling limiting piston that described each demoulding swing arm top is established driving cylinder respectively and driven by driving cylinder, the driving direction of described driving cylinder is variable.
The present invention carries out according to the following steps:
1) first require to determine the depth of fill of each section of powder according to goods, then by primary filling guiding mechanism, secondary filling adjusting mechanism ..., n filling adjusting mechanism adjust the position of each filling adjustment Limit screw; Then the position of each demoulding swing arm is determined according to the position of each filling adjustment Limit screw, namely the corresponding primary filling adjustment in the position of demoulding swing arm Limit screw position ..., n-1 demoulding swing arm the position of corresponding this filling of the n-1 adjustment in position Limit screw, and by each demoulding swing arm locking;
2) die cavity mechanism moves upward under the drive of reset cylinder, until stop when encountering primary filling adjustment Limit screw, primary filling terminates;
3) remove a demoulding swing arm, die cavity mechanism continues to move upward under the drive of reset cylinder, until stop when encountering secondary filling adjustment Limit screw, secondary sand off;
4) 3 are repeated) step, until n sand off;
5) after sand off, the descending compacting of upper punch makes product molding, and the rear demoulding obtains.
The course of work of the present invention is elaborated below: 1) first the present invention requires to determine the depth of fill of one, two powder according to goods with secondary feeding, secondary filling, thus adjust by first and second filling adjusting mechanism the position that each filling adjusts Limit screw, and set the action of each gas, liquid, electric system; Control the airdraulic actuator epicoele normal open gas of the depth of fill of one, two powder, to make filling limiting piston in the floating of face prevention demoulding swing arm bottom, thus the floating of die face in controlling, realize filling needs, the power upwards that the power that the pressure of driving cylinder cylinder of the present invention should make filling limiting piston produce produces slightly larger than reset cylinder;
2) after the machine demoulding starts, along with going deep into of the demoulding, feeding swing arm drives material boots to move forward under the effect of demoulding cam; The demoulding terminates, goods deviate from die cavity completely, now feeding cam goes to isometrical section of A-B from F, and now expect boots pushing out product and expect that boots chamber is directly over die cavity, first time filling starts, and middle die face is moved upward to and encounters primary filling adjustment Limit screw and stopping under the promotion of reset cylinder, first time filling, feeding terminate;
3) magnetic valve controlling driving cylinder commutates under the control of PLC, and filling limiting piston constraint relief moves up, and demoulding swing arm moves up immediately, and middle die face moves up until encounter secondary filling adjustment Limit screw and stop under the promotion of reset cylinder; Now feeding cam goes to C-D from isometrical section of A-B, carries out feeding filling above same feeding material boots chamber rollback to middle die face die cavity, second time feeding sand off;
4) last feeding cam is converted to isometrical section of E-F from isometrical section of C-D, and material boots can fall back on rearmost, and upper punch is descending carries out pressed ware, the machine run demoulding again, feeding, filling, completes and once circulates.
Be more than the forming method of two layers of pulverulent product, the forming method principle of multiple layer powder goods is the same.
