Abstract
The utility model relates to a kind of core bar driving device, which is mounted on powder hydraulic press, it is characterised in that: including central cylinder, extension bar, lower template, guide post and attaching nut；The central cylinder with pneumatic type in the utility model by being arranged in lower template, piston rod movement is driven by the central cylinder of pneumatic type, to adjust the initial position of lower template upper piston rod, to realize the core bar in lower template in the driving of vertical direction, compared to the labyrinth in being driven in single core bar structure using structure of taking blame for others, more structure is simple by the way of the central cylinder of air-cylinder type, facilitates adjusting.
Description
Technical field
The utility model relates to powder Hydraulic Field more particularly to a kind of core bar driving devices.
Background technique
Powder metallurgy is to produce metal or use metal powder (or mixture of metal powder and non-metal powder) as original
Material manufactures metal material, compound and various types product technique skill by sintering again after having pressure or shaping without pressure
Art.PM technique has significant energy conservation, material saving, has excellent performance, the series of advantages such as Product Precision is high and stability is good, non-
It is very suitable for producing in enormous quantities.Currently, PM technique has been widely used in traffic, machinery, electronics, aerospace, soldier
The fields such as device, biology, new energy, information and nuclear industry become one of the branch of most development vitality in new material science.With
The rapid development of domestic powder technology, many metal materials are all made of powder compacting technology, i.e., will be golden by powder shaping press
Belong to powder and be pressed into pie, then metal product is made by being sintered.
Currently, the core bar of powder hydraulic press can not be adjusted, the row of the rough control centre's cylinder of hydraulic cylinder can only be passed through
Journey, precision is lower, and to the product with some high-precision requirements, the stroke control precision of core bar is low, then can seriously affect product
Precision.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of core bar driving devices, are able to solve general adjusting machine
The initial position in core bar punching course is adjusted in structure realization, controls the stroke accuracy of core bar.
In order to solve the above technical problems, the technical solution of the utility model are as follows: a kind of core bar driving device, core bar driving
Device is mounted on powder hydraulic press, and innovative point is: including central cylinder, extension bar, lower template, guide post and attaching nut；
The central cylinder includes outer cylinder sheath and piston rod, and outer cylinder sheath and piston rod form air cylinder structure；The outer cylinder sheath leans on
Bolt hole along the vertical direction is provided at nearly outer wall, the outer cylinder sheath is connected horizontally on the upper end of lower template by assembling bolt
On face, port is provided on the outer cylinder sheath, outer cylinder sheath is provided with the air cavity for accommodating piston rod in the axial direction；The piston rod is set
It sets in outer cylinder sheath air cavity and is slided along the inner wall of outer cylinder sheath, the piston rod is provided with the circle for accommodating extension bar along axis direction
Post holes is provided with washer at the upper port of the piston rod；
The extension bar is arranged vertically in piston rod, is provided with limit on the extension bar and above washer
Nut；
The lower template is located at the lower section of central cylinder, is provided in lower template and accommodates the through-hole that extension bar passes through；
The guide post is arranged vertically at the upper of lower template and passes through lower template, the bottom end of the guide post and lower template
Bottom end between by attaching nut be connected.
Further, the extension bar has several segments, is connected between extension bar by link block.
Further, the air cavity, cylindrical hole and through-hole coaxial arrangement.
Utility model has the advantages that
1) center of pneumatic type is passed through by the central cylinder with pneumatic type being arranged in lower template in the utility model
Cylinder drives piston rod movement, so that the initial position of lower template upper piston rod is adjusted, to realize that the core bar in lower template is erecting
Histogram to driving, compared to using take blame for others structure driven in single core bar structure in labyrinth, using air-cylinder type
Central cylinder mode more structure it is simple, facilitate adjusting.
