Abstract
The invention provides a cold extrusion molding device for an aluminum alloy seamless tube. The cold extrusion molding device for the aluminum alloy seamless tube is characterized in that a lower mould I with a center hole, and a lower mould II with a center hole are sequentially upwards mounted on a bottom board; a core rod type hydraulic cylinder is arranged in the center of an upper mould board; beam type hydraulic cylinders are respectively mounted at two upper sides of the upper mould board; a piston rod of the core rod hydraulic cylinder is downwards connected with a core rod; piston rods of the two beam hydraulic cylinders are downwards connected above a beam; the center of the beam is downwards connected with an upper mould with a center hole; the core rod passes through the center hole of the upper mould; and the lower end of the upper mould and the center hole of the lower mould I are matched. By using the cold extrusion molding device for the aluminum alloy seamless tube, provided by the invention, to machine the aluminum alloy seamless tube, an aluminum alloy raw material has no need of being heated, and is molded by cold extrusion at a constant temperature state. With the adoption of a vertical type hydraulic machine, an upper mold and a lower mold are arranged at the lower part of the hydraulic machine, so that the aluminum alloy seamless tubes with different diameters can be formed by changing the diameters of inner holes of the two molds. The cold extrusion molding device for the aluminum alloy seamless tube has the advantages of low cost, high machining efficiency, no need of heating, no need of consuming coal and electricity, emission reduction, and energy conversation and environment friendliness.
Description
Technical field
The invention belongs to aluminium alloy seamless pipe cold extrusion forming equipment, particularly a kind of aluminium alloy seamless pipe cold extrusion forming device.
Background technology
The process technology of aluminium alloy seamless pipe is to aluminium ingot heating, coordinates extrusion modling by mould after reaching uniform temperature.Shortcoming is to heat raw material of aluminum alloy, needs to consume electric energy, and working (machining) efficiency is low.
Summary of the invention
Technical problem to be solved by this invention is: a kind of aluminium alloy seamless pipe cold extrusion forming device is provided.
Technical scheme of the present invention is:
A kind of aluminium alloy seamless pipe cold extrusion forming device is characterized in that: counterdie I and counterdie II upwards are housed on base plate successively, and there is centre bore at the center of counterdie I and counterdie II; Wherein the centre bore of counterdie II is the bevelled funnel-shaped hole of tool from top to bottom successively, and funnel-shaped hole lower end connection has the annular tough with holes of projection, and the lower end annular tough with holes with projection connects greater than the hole with protruding annular ligament bore dia; The core bar hydraulic cylinder is equipped with at the center on cope match-plate pattern, and a crossbeam hydraulic cylinder respectively is equipped with in both sides on cope match-plate pattern; The piston rod of core bar hydraulic cylinder connects core bar downwards; The piston rod of two crossbeam hydraulic cylinders is connected to crossbeam top downwards, and the crossbeam center is connected with the patrix of centre bore downwards; Core bar is through in the centre bore of patrix; The patrix lower end coordinates with the centre bore of counterdie I.
Effect of the present invention is:
Adopt this device processing aluminium alloy seamless pipe, raw material of aluminum alloy need not heat, and the normal temperature state is cold extrusion shaped.Utilize vertical hydraulic press, be provided with upper and lower mould in the hydraulic press bottom, can form by the diameter of bore that changes two moulds the aluminium alloy seamless pipe of different-diameter.Advantage is exactly that cost is low, and working (machining) efficiency is high, does not need heating, and is electric without coal combustion, reduces discharging, energy-conserving and environment-protective.
Description of drawings
Fig. 1 is the structure chart of aluminium alloy seamless pipe cold extrusion forming device.
Fig. 2 is the local structural graph of aluminium alloy seamless pipe cold extrusion forming device.
In figure: 1 base plate, 2 counterdie I, 3 counterdie II, 4 crossbeams, 5 core bar hydraulic cylinders, 6 and 8 crossbeam hydraulic cylinders, 7 cope match-plate patterns, 9 patrixes, 10 core bars, 11 funnel-shaped holes, 12 have the annular tough with holes of projection, 13 holes greater than the annular ligament bore dia with projection, 14 aluminium alloy material pieces.
The specific embodiment
As shown in Figure 1: a kind of aluminium alloy seamless pipe cold extrusion forming device, counterdie I and counterdie II upwards are housed on base plate successively, there is centre bore at the center of counterdie I and counterdie II; Wherein the centre bore of counterdie II is the bevelled funnel-shaped hole of tool from top to bottom successively, and funnel-shaped hole lower end connection has the annular tough with holes of projection, and the lower end annular tough with holes with projection connects greater than the hole with protruding annular ligament bore dia; The core bar hydraulic cylinder is equipped with at the center on cope match-plate pattern, and a crossbeam hydraulic cylinder respectively is equipped with in both sides on cope match-plate pattern; The piston rod of core bar hydraulic cylinder connects core bar downwards; The piston rod of two crossbeam hydraulic cylinders is connected to crossbeam top downwards, and the crossbeam center is connected with the patrix of centre bore downwards; Core bar is through in the centre bore of patrix; The patrix lower end coordinates with the centre bore of counterdie I.
Core bar hydraulic cylinder 5 is controlled 10 core bars and is moved up and down, and crossbeam hydraulic cylinder 6 and crossbeam hydraulic cylinder 8 are controlled moving up and down of crossbeam 4 for controlling the hydraulic cylinder of crossbeam 4.The below of core bar 10 is the nose bars with fixed diameter, and effect is to control warp in seamless pipe.Counterdie I and counterdie II are hollow mould.Wherein the mesopore of counterdie II is to have the inclined-plane characteristic, and the annular ligament of projection is arranged in the inclined-plane end, and the internal diameter at ligament place is the external diameter of the seamless pipe of machine-shaping.Counterdie I and counterdie II are fixed on base plate 1 jointly.Patrix 9 has mesopore, core bar 10 freely action up and down therein.Patrix 9 is fixed on crossbeam 4.
Use this device processing aluminium alloy seamless pipe cold extrusion forming process: columniform aluminium alloy material piece 14 with mesopore is positioned in counterdie 13, core bar 10 comes downwards to over material piece position, then patrix 9 is descending, extruding aluminium alloy material piece, make its distortion, but the direction of distortion is along the zone of the ligament of counterdie II and core bar 10 encirclements, has formed the aluminium alloy seamless pipe.Can be by changing the interior external diameter of controlling the aluminium alloy seamless pipe through size of counterdie I and counterdie II, change the interior warp of aluminium alloy seamless pipe by the diameter that changes core bar lower end taper end.
