Description
Technical field
The present invention relates to a kind of vertical extrusion die of deep hole, be specifically related to a kind of dovetail slideway pneumatic type upper mold and move horizontally deep hole
Vertical extrusion die, belongs to machining punching press specialty Design of Dies technical field.
Background technology
Extruding is that the one of forging and stamping processing is less or without cutting technology.Conventional extrusion mould, works under lower mold assemblies and equipment
Platform is fixed, and upper die component is fixed with equipment top shoe, no matter upper die component or lower mold assemblies, the horizontal direction of relative device
Being all fixing, simply upper die component is along with the up and down motion of equipment top shoe, and the Guan Bi of extrusion equipment is highly greater than lower module
Part height adds upper die component height plus workpiece height, and otherwise after extruding, workpiece cannot take out from die.At present,
Processing penetration body (penetration body is the extrusion that the longer endoporus of a kind of profile is deeper, wherein profile reach 1.18 meters for longer,
Bore depth reaches 0.91 for deeper) parts were welded to form by head and stack shell two parts originally, head by extruded,
Owing to extrusion equipment Guan Bi is the least, it is impossible to monolithic extruded penetration body, can only squeeze bulb blank warp, the most again and stack shell
Being welded, both welding cost expenses, about at about 2000 yuan, are welded costly, in order to reduce manufacturing cost,
Without welding procedure, by monolithic extruded for penetration body shaping, if designing extrusion die routinely, existing equipment closes the most not
Extruding requirement can be met, if again purchasing the extrusion equipment of big Guan Bi height, needing to invest 7,800,000 yuan, disposably putting into
Relatively big, after extruding, economic benefit is inconspicuous, even loses more than gain.
Therefore, there is device closed height and can not meet traditional dies in existing production for the profile deeper extrusion of longer endoporus
The situation of design, and the problem that production cost is high.
Summary of the invention
