Abstract
The invention discloses a seamless tubing extrusion device which comprises an extrusion barrel. The seamless tubing extrusion device is characterized by further comprising an extrusion rod, an extrusion needle and an extrusion die. A molding core is arranged on the extrusion die, a slide groove is arranged in the extrusion barrel, the extrusion rod capable of sliding back and forth along the slide groove is arranged in the slide groove, the extrusion needle is arranged at the front end of the extrusion rod, and a billet is arranged between the extrusion rod and the extrusion die. By the aid of the seamless tubing extrusion device, the problems of complex overall structure, high cost, and complex processing operation of operation staff due to the fact that a punch is used for forward extrusion of seamless tubing are solved, and the problems that the billet is inconveniently clamped and processed on the punch through a clamping device so that overall processing efficiency is affected, and when a hollow part of the middle of the seamless tubing is extruded, the hollow part is easy to produce burrs and using is affected due to the fact that stress is not uniform are also solved. Accordingly, the seamless tubing extrusion device is simple in structure, quick in molding and free of the burrs, and finished products are fine in quality.
Description
Technical field
The present invention relates to a kind of pressurizing unit, particularly relate to a kind of seamless tube extruding device.
Background technology
Seamless tubular goods be a kind ofly have hollow section, periphery does not have jointed circle, and is square, rectangle pipe material.Seamless tubular goods is to make hollow billet with steel ingot or the solid pipe hole that wears long, and then makes through hot rolling, cold rolling or cold group.Seamless tubular goods has hollow section, a large amount of pipelines as carrying fluid, steel pipe is compared with solid steel such as round steel, when the bending resistance torsional strength is identical, weight is lighter, be a kind of Economic Section steel, be widely used in manufacturing structure spare and machine components, as steel scaffold of using in oil drill rocker, truck drive shaft, bicycle rack and construction etc.
Present seamless tubular goods forward extrusion adopts punch press to push more, complicated integral structure, and cost is high, and it is also comparatively loaded down with trivial details that operating personnel operate processing.Also very bother for the processing billet by the clamping device clamping on punch press simultaneously, the working (machining) efficiency that impact is whole can not satisfy the needs that rapid processing is produced.During the hollow part in the middle of seamless tube extruding, due to stressed even not, and directly act on without buffering in addition.Cause the seamless tubular goods hollow part easily to produce burr, impact is used.
Summary of the invention
Adopt punch press to push in order to solve in prior art the seamless tubular goods forward extrusion more, complicated integral structure, cost is high, and it is also comparatively loaded down with trivial details that operating personnel operate processing.Also very bother for the processing billet by the clamping device clamping on punch press simultaneously, the working (machining) efficiency that impact is whole, and during the hollow part in the middle of seamless tube extruding, due to stressed even not, cause hollow part easily to produce burr, the problem that impact is used, the invention provides a kind of simple in structure, moulding is quick, and without burr, manufactured goods have the seamless tube extruding device of better quality.
In order to address the above problem, the technical solution used in the present invention is:
A kind of seamless tube extruding device, comprise recipient, it is characterized in that: also comprise pressure ram, squeezing needle and extrusion die, be provided with building core on extrusion die, offer chute in recipient, be provided with the pressure ram that can slide before and after the chute in chute, be provided with squeezing needle at the front end of pressure ram, be provided with billet between pressure ram and extrusion die.
Aforesaid a kind of seamless tube extruding device is characterized in that: be provided with in the front center of pressure ram and can pass billet and extend into extruding and touch squeezing needle in building core.
Aforesaid a kind of seamless tube extruding device is characterized in that: also comprise dummy block, between pressure ram and billet, be provided with the dummy block that plays cushioning effect in the both sides of squeezing needle.
The invention has the beneficial effects as follows: the present invention is positioned over billet between dummy block and extrusion die, then utilize pressure ram to move in chute, push billet and obtain manufactured goods, clamping is quick, and working (machining) efficiency is high, and whole installation cost is lower, utilize simultaneously squeezing needle to come the extruded stock ingot shape to become the hollow of tubing, because the front center at pressure ram is provided with dummy block, make billet extruded hollow position stressed more even, can not produce burr like this, guarantee that manufactured goods have quality preferably.
Description of drawings
Fig. 1 is the structural representation of seamless tube extruding device of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of seamless tube extruding device, comprise pressure ram 1, recipient 2, dummy block 3, billet 4, squeezing needle 5 and extrusion die 6, be provided with building core on extrusion die 6, offer chute in recipient 2, be provided with the pressure ram 1 that can slide before and after the chute in chute, be provided with in the front center of pressure ram 1 and can pass billet and extend into extruding and touch squeezing needle 5 in 6 building cores, be provided with billet 4 between pressure ram 1 and extrusion die 6.Between pressure ram 1 and billet 4, be provided with the dummy block 3 that plays cushioning effect in the both sides of squeezing needle 5.
The present invention is positioned over billet 4 between dummy block 3 and extrusion die 6, then utilize pressure ram 1 to move in chute, push billet 4 and obtain manufactured goods 7, clamping is quick, and working (machining) efficiency is high, and whole installation cost is lower, utilize simultaneously squeezing needle 5 to push billet 4 relevant positions and form the hollow of tubing, because the front center at pressure ram 1 is provided with dummy block 3, make billet 4 extrusion positions stressed more even, can not produce burr like this, guarantee that manufactured goods have quality preferably.
Above demonstration and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
