Description
Technical field: the utility model relates to a kind of die casting machine quantitative feed device, is mainly used in the extrusion process of magnesium alloy.
Background technology: at present, domestic magnesium alloy pressure-casting Processes and apparatus still is in initial research and application stage.Manual type is mainly adopted in the production of most of die castings, and safety coefficient is low; Because the chemical property of magnesium alloy is active, be easy to oxidizing fire simultaneously, cause the quality of die casting not reach the part specification requirement, thereby can't produce in batches.
Summary of the invention: the utility model is in order to overcome the shortcoming of manually watering material, guarantee product quality, improve safety coefficient, different with valve class control magnesium alloy liquation quantitative conveyer in the past, the utility model provides a kind of die casting machine step-by-step movement magnesium-alloy quantitative pay-off, it is characterized in that: described device mainly comprises stepper motor, transmission mechanism, material storing box, shot sleeve and the insulation conveyance conduit of microprocessor controller control; Described shot sleeve is fixed on the frame, places in the material storing box, and casing wall offers charging aperture, and discharge end and described insulation conveyance conduit link; The piston of described shot sleeve is positioned at feed end, and is connected with described transmission mechanism; Described transmission mechanism is made of ball guide screw nat and connecting rod, and ball guide screw nat is connected with described motor by shaft joint, links by described connecting rod and piston.
This device is realized the accurate control to piston traveling speed and distance by adopting microprocessor controller control step motor revolution and rotating speed, thereby reaches the purpose of quantitative feed.Realize the quantitative conveying of magnesium alloy liquation in the production process, substituted and manually water material, improved operating efficiency, safety coefficient and product quality, reduced production cost.
Description of drawings: Fig. 1 is the utility model die casting machine step-by-step movement magnesium-alloy quantitative pay-off feed state schematic diagram;
Fig. 2 is the utility model die casting machine step-by-step movement magnesium-alloy quantitative pay-off discharging view;
Fig. 3 is that the utility model die casting machine is incubated the conveyance conduit schematic diagram with step-by-step movement magnesium-alloy quantitative pay-off.
The specific embodiment: as shown in Figure 1, this step-by-step movement magnesium-alloy quantitative pay-off mainly comprises stepper motor 1, transmission mechanism, material storing box 7, shot sleeve 10, insulation conveyance conduit 12, wherein stepper motor 1 adopts microprocessor controller control revolution and rotating speed, is fixed on the frame 2; Shot sleeve 10 is fixing by frame 2, and places in the material storing box 7, and casing wall offers charging aperture 9, discharging termination insulation conveyance conduit 12.Place the piston 8 in the shot sleeve 10 to be positioned at the shot sleeve feed end, and be connected with the transmission mechanism of motor 1 driving.Transmission mechanism is made of ball guide screw nat 4 and connecting rod 5, and ball guide screw nat 4 is connected with motor 1 by shaft joint 3, links by connecting rod 5 and piston 8.In order to guarantee accurately moving of piston 8, between piston 8 and ball guide screw nat 4, increase by a rolling guide 6, connect by connecting rod 5.The utility model is by adopting the revolution and the rotating speed of microprocessor controller control step motor 1, and driving precision ball screw pair of nut 4 is realized piston 8 translational speeds and accurately control of distance, thereby reaches the purpose of quantitative feed.
As shown in Figure 1, during charging, stepper motor 1 is the rotating speed rotation to set under the control of microprocessor controller, drives precision ball screw pair of nut 4 by shaft coupling 3, drives piston 7 assemblies that link with nut and moves upward along directed rolling guide 6.When the lower edge of piston 8 upwards surpassed charging aperture 9, the magnesium alloy liquation in the material storing box 7 entered by charging aperture 9 and finishes the charging action in the shot sleeve 10.
As shown in Figure 2, during discharging, stepper motor 1 drives 4 counter-rotatings of precision ball screw pair of nut, drives piston 8 and moves downward.When piston 8 was descending, charging aperture 9 was sealed by piston 8, stoped the alloy liquation to enter shot sleeve 10, and the magnesium alloy liquation that will enter simultaneously in the shot sleeve 10 is pressed in the insulation conveyance conduit 12, thereby magnesium alloy solution is transported on the die casting machine.Set stepper motor 1 rotation revolution in the microprocessor controller, its correspondence the movement travel of piston 8, and this has also just controlled charging aperture 9 openings of sizes, and then injection is gone out from shot sleeve 10 alloy liquid what have been controlled.
As shown in Figure 3, insulation conveyance conduit 12 is made up of parts such as pipe 13, resistance heater 14, heat-insulation layer 15 in heat-resisting, and protective gas enters in the pipe by gas atmosphere inlet 11, can prevent the oxidation of magnesium alloy liquation effectively.The holding temperature of insulation carrier pipe 12 can freely be set, and operated by rotary motion prevents that the magnesium alloy liquation from solidifying, and blocks pipeline when carrying between 600～650 ℃.Insulation conveyance conduit 12 adopts resistance heated mode and gas shield, makes pipe temperature be controlled at 600～650 ℃, has guaranteed that the magnesium alloy liquation does not solidify in sending into the process of die casting machine, not oxidation, has improved the quality of alloy liquid.
