Abstract
The utility model discloses an extrusion rod for extrusion forming, and belongs to the field of sectional material processing. The extrusion rod comprises a cylindrical main body one end of which is provided with an opening end, wherein the opening end of the cylindrical main body is in threaded connection with a pressure head, and the cylindrical main body is internally provided with a spring; the pressure head is provided with a coaxial through hole of the spring, the through hole is internally provided with an inner supporting rod in an inserting way with intervals, the front end of the inner supporting rod is fixedly connected with a rod head, and the rod head is arranged in the cylindrical main body in the interval manner. The extrusion rod provided by the utility model has the advantages that the formation of a die region is reduced, the extrusion force is greatly reduced, the burden of power equipment is lighted, the energy consumption is reduced, the burden of a mould is relieved, and the service life of the mould is prolonged; meanwhile, the distance from a central metal material of a blank to the edge of a radiator is reduced, the flow rate difference of metal is reduced better, the flow rate is uniform, and the flowing property of metal is well improved.
Description
Technical field
The utility model genotype material manufacture field, particularly a kind of production apparatus technical field that adopts tubular blank to produce the heronsbill shaped material of radiator.
Background technology
Being applied in of radiator is now more and more wider, has related in a lot of fields.Shaped material of radiator much all adopts hot extrusion production to complete, and is to use solid blank mostly in production process.But larger for some external diameters in actual production process, radiation tooth higher heronsbill radiator production difficulty still larger, main cause is: the extruding proparea exists that serious dead band phenomenon, metal charge flow difficulties, extruding force are large, die life is short etc.
Summary of the invention
The utility model purpose is to propose a kind of extrusion molding pressure ram for adopting tubular blank production heronsbill shaped material of radiator.
The utility model comprises that an end is the tubular body that is provided with openend, at the openend of the described tubular body pressure head that is threaded, in described tubular body, spring is set, offer on described pressure head and the homoaxial through hole of described spring, at the interspersed inner bracing piece of described through hole internal clearance formula, the front end fixed connecting rod head of inner bracing piece, described bar head clearance-type is arranged in tubular body.
Before the extruding beginning, along with inner bracing piece takes the lead in stretching in tubular blank, the bar head is played a supporting role, to prevent that metal charge flows to the place, axle center in extrusion process.Carrying out along with extruding, after the bar head of pressure ram front end touches blank, it is exerted pressure, flow forward along the direction of extrusion under the condition of three-dimensional compressive stress, owing to having adopted tubular blank, the corresponding minimizing of the contact area of blank and mould, reduced the formation in dead band in extrusion process, greatly reduce extruding force, alleviate the burden of power-equipment, reduced energy consumption, alleviated the life-span that the burden of mould has improved mould.Simultaneously expect the distance at radiator edge and reduced due to the metal in blank bosom in this, can well reduce the current difference of metal, its flow velocity is tending towards evenly, well improved the mobile performance of metal.
In addition, the external diameter of described inner bracing piece rear end is the tapering transition face that reduces gradually.It can be separated with defective material after extruding is completed well, be convenient to follow-up production.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises that an end is the tubular body 1 that is provided with openend, at the interior spring 3 that arranges of tubular body 1, at the openend of tubular body 1 pressure head 2 that is threaded, offer on pressure head 2 and the homoaxial through hole 4 of spring 3, at the interspersed inner bracing piece 5 of through hole 4 internal clearance formulas, the front end fixed connecting rod head 6 of inner bracing piece 5, these bar head 6 clearance-types are arranged in tubular body 1, and the external diameter of inner bracing piece 5 rear ends is the tapering transition face 7 that reduces gradually.
Claims (2)
1. extrusion molding pressure ram, comprise that an end is the tubular body that is provided with openend, it is characterized in that: at the openend of the described tubular body pressure head that is threaded, in described tubular body, spring is set, offer on described pressure head and the homoaxial through hole of described spring, at the interspersed inner bracing piece of described through hole internal clearance formula, the front end fixed connecting rod head of inner bracing piece, described bar head clearance-type is arranged in tubular body.
2. extrusion molding pressure ram according to claim 1 is characterized in that: the external diameter of described inner bracing piece rear end is the tapering transition face that reduces gradually.
