Abstract
The invention relates to a filling adjusting mechanism of a powder former, which belongs to the technical filed of powder product forming machinery. The filling adjusting mechanism comprises an adjusting mechanism which is controlled by a PLC. The adjusting motor drives an adjusting screw to move up and down by a transmission mechanism. The adjusting screw is driven by a swinging arm lever to move up and down along with a lower main shaft which is connected by swing arm level and a die. The outside of the adjusting screw is provided with an over and under pressure mechanism which consists of an over and under oil cylinder and a filling piston. The adjusting screw and the over and under pressure mechanism are split, and the filling adjusting mechanism is arranged outside the machine tool body. The invention has the advantages that the filling adjusting mechanism is arranged outside the machine tool bed, therefore the installation and debugging are convenient; the over and under pressure mechanism which consists of the over and under oil cylinder and the filling piston, and the adjusting screw are split and then assembled, therefore the structure is simple, the cost is low, the structure is easy to guarantee, and the stability and reliability are high when in work.
Description
Technical field
The present invention relates to filling adjusting mechanism of powder former, belong to pulverulent product forming machine technical field.
Background technology
Pulverulent product is in forming process, because actual needs need be controlled the filling state of powder, be divided into powder filling and cross the amount of owing filling, there is following defective in filling adjusting mechanism of powder former in the past: 1) design is installed with adjustment extremely inconvenient in the fuselage inboard; 2) original structure is crossed and owed gauging cylinder and piston and adjustment screw mandrel and be designed to integrative-structure, and is complicated on the structure, processing difficulties and cost height, and also the precision that processes is difficult to guarantee that the stability when making mechanism's real work, reliability can not get guaranteeing.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide a kind of installation, debugging conveniently, the filling adjusting mechanism of powder former of stability, good reliability during work.
Technical scheme of the present invention is: the present invention includes the adjustment motor by PLC control, adjusting motor moves up and down by transmission mechanism drive adjustment screw mandrel, adjusting screw mandrel moves up and down by the lower main axis that the swing arm lever drives is connected with die, adjusting the screw mandrel outside is provided with by crossing and owes the mistake that gauging cylinder and filling piston form and owe the piezometric force mechanisms, adjust screw mandrel and cross and owe between the piezometric force mechanisms to split design, filling adjusting mechanism designs outside lathe bed.
The invention has the beneficial effects as follows: 1) filling adjusting mechanism is installed in the lathe bed outside, makes things convenient for installation and debugging; 2) cross owe mistake that gauging cylinder and piston form owe the piezometric force mechanisms with adjust screw mandrel separate design after with its assembling, cost simple in structure is low, is easy to assurance, the stability during work, reliability height.
Description of drawings
Fig. 1 is a structural representation of the present invention
Among the figure 1 for lower main axis, 2 be owe the gauging cylinder, 3 for the filling piston, 4 for adjust gear wheel, 5 for pinion, 6 for adjust screw mandrel, 7 for stop pin, 8 be that swing arm lever, 11 is a bevel gear for adjusting power transmission shaft, 9 for adjusting motor, 10.
The specific embodiment
The present invention includes adjustment motor 9 by PLC control, adjusting motor 9 moves up and down by transmission mechanism drive adjustment screw mandrel 6, adjusting screw mandrel 6 moves up and down by the lower main axis 1 that 10 drives of swing arm lever are connected with die, adjusting screw mandrel 6 outsides is provided with by crossing and owes the mistake that gauging cylinder 2 and filling piston 3 form and owe the piezometric force mechanisms, adjust screw mandrel 6 and cross and owe between the piezometric force mechanisms to split design, filling adjusting mechanism designs outside lathe bed.
Operation principle of the present invention is: the rotation number of turns of adjusting motor 9 by PLC control and calculating, driving adjustment screw mandrel 6 by bevel gear 11, gear pair transmission moves up and down, and the realization of powder filling and adjustment are the realizations that moves up and down by lower main axis 1, the position that moves up and down of lower main axis 1 has in fact just been controlled in the mobile adjustment of adjusting screw mandrel 6, the final adjustment that realizes filling powder height.Cross the principle of the amount of owing filling: after carrying out sand off after the filling position is determined, feeding pressure oil by airdraulic actuator moves filling piston 3 up or down, finally make lower main axis 1 move up and down a short stroke, thereby make concave die cavity form one and owe powdery attitude and many powderies attitude, to adapt to the moulding requirement of different pulverulent products, for adjustment screw mandrel 6 self is not rotated, the present invention sets up defences in adjustment screw mandrel 6 outsides and ships and resell on another market.
Operation acts of the present invention is: motor 9 rotations are adjusted in normal filling adjustment: PLC control, driving adjustment power transmission shaft 8 by bevel gear 11 rotates, drive and adjust power transmission shaft 8 drive drive pinions 6, adjust gear wheel 4 a pair of gear pairs runnings, adjusting gear wheel 4 moves up and down by screw thread drive adjustment screw mandrel 6, the variation of control swing arm lever 10 upper-lower positions, swing arm lever 10 drives lower main axis 1 and moves up and down, and the die die cavity that drives mould bases forms the filling state.
Cross the amount of owing filling: after filling is adjusted, material boots feeding forward carry out filling to the die die cavity, and after powder filling finished, PLC control magnetic valve made owed gauging cylinder 2 upper ends feeding pressure oil, filling piston 3 action downwards drives adjustment screw mandrel 6 and moves downward, it is downward finally to drive lower main axis 1 by swing arm lever 10, owing to down towards motionless, matrix cavity is shortened, powder has more by the material boots and takes back during return backward, excessive filling state is finished, otherwise filling piston 3 upwards action then is the amount of owing filling state.
Claims (1)
1. filling adjusting mechanism of powder former, comprise adjustment motor by PLC control, adjusting motor moves up and down by transmission mechanism drive adjustment screw mandrel, adjusting screw mandrel moves up and down by the lower main axis that the swing arm lever drives is connected with die, adjusting the screw mandrel outside is provided with by crossing and owes the mistake that gauging cylinder and filling piston form and owe the piezometric force mechanisms, it is characterized in that adjust screw mandrel and cross and owe between the piezometric force mechanisms to split design, filling adjusting mechanism designs outside lathe bed.
