Description
Technical field
This utility model is related to power metallurgy equipment field, more particularly to a kind of lower plug of powder compaction device
Automatic riser.
Background technology
With expanding economy, PM technique range of application is more and more extensive, in each department of national economy, almost
There is mould processing, it is not only closely related with whole machinery industry, and closely coupled with the life of people.Due to powder
Last metallurgical technology have production efficiency height, steady quality, low cost and can the series of advantages such as manufacturing complex shapes workpiece,
The sector applications such as automobile, light industry, appliances motor, household electrical appliance, Aero-Space and daily living article are more and more extensive.With
The continuous development of industrial products and production technology level it is continuous, powder compaction device is as Modern High-Speed forming technique in technique
Increasing effect is played in equipment.
Existing powder compaction device is only adapted to suppress the little product of tonnage, it is impossible to meet compacting large-tonnage product
Compacting demand.This is because if product tonnage is larger, Design of Dies structure needs to use the automatic lifting mechanism of plug to core
Rod is lifted just can be suppressed, if full automatic mechanical press somewhat expensive is bought, and hydraulic press carries in itself action
The demand that plug is moved automatically can not be met.
Utility model content
In order to overcome the defect of prior art, technical problem to be solved in the utility model is to propose a kind of powder pressure
The automatic riser of lower plug of molding jig, can realize the compacting of large-tonnage product, and simple structure, significantly reduce into
This, and efficiently solve the problems, such as that lower plug rises automatically.
It is that, up to this purpose, this utility model is employed the following technical solutions：
The present invention provide a kind of powder compaction device the automatic riser of lower plug, including upper plug, lower plug and
Spring, the upper part contact of the upper plug and the lower plug, and the two relative disPlacement motion, the lower plug and the bullet
Spring is coaxially disposed, and the lower plug is located at the top of the spring, and between the lower plug and the spring plug pad is provided with
Plate, the lower end of the lower plug is fixed on the plug backing plate.
In this utility model preferably technical scheme, also including upper press cover, internal diameter and institute are provided with the upper press cover
The shoulder hole that lower plug external diameter is adapted is stated, the lower plug passes through the shoulder hole.
In this utility model preferably technical scheme, also including shell body, the spring is located at the chamber of the shell body
Interior, the shell body is threadedly coupled with the upper press cover.
In this utility model preferably technical scheme, also including base pressure lid, the base pressure lid is located at the spring bottom,
The base pressure lid is threadedly coupled with shell body.
The beneficial effects of the utility model are：
The automatic riser of lower plug of the powder compaction device that this utility model is provided, spring is placed in below lower plug.
After filling is completed, in suppression process, upper plug press against lower plug down motion shaped article, after formed product is completed, on
Plug drawback movement, by backhaul after spring active force upwards, be then engage in next step rushes powder action to lower plug.Using spring
Replace lower plug backhaul equipment, effectively reduce the expense of the purchase component such as backhaul action equipment and cylinder, effectively reduce
The cost of the automatic riser of lower plug.

Specific embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by specific embodiment.
As shown in figure 1, a kind of automatic riser of lower plug of powder compaction device is provided in embodiment, including upper core
Rod 1, lower plug 2 and spring 6, the upper part contact of upper plug 1 and lower plug 2, and the two relative disPlacement motion, lower plug 2 with
Spring 6 is coaxially disposed, and lower plug 2 is located at the top of spring 6, and plug backing plate 4, lower plug are provided between lower plug 2 and spring 6
2 lower end is fixed on plug backing plate 4, meeting extrusion spring 6 when lower plug 2 is moved downward, under the storage elastic force potential energy of spring 6 drives
The drawback movement of plug 2.Specifically, after powder compaction device filling is completed, in suppression process, the lower core of the compacting of upper plug 1
Rod 2 is down moved and completes formed product, then goes up the drawback movement of plug 1, and lower plug 2 receives backhaul after the active force upwards of spring 6,
Then wait next step rushes powder action.Large-tonnage can not only be realized using the automatic riser of lower plug with spring 6
Product compacting, and simple structure compares other equipment and completes the backhaul of lower plug 2, and cost is greatly reduced.
In order to limit the displacement of lower plug 2, and beneficial to the installation and fixation of lower plug 2.Further technical scheme, lower plug
Automatically riser also includes upper press cover 3, and the shoulder hole 8 that internal diameter is adapted with the lower external diameter of plug 2 is provided with upper press cover 3, under
Plug 2 passes through shoulder hole 8.The radial displacement of lower plug 2 can effectively be limited by shoulder hole 8, it is ensured that the jail that lower plug 2 is installed
Solidity.
For the radial displacement of limited spring 6, it is ensured that spring 6 carries out translation along its axis.Further technical scheme,
The automatic riser of lower plug also includes shell body 5, and spring 6 is located at the within the chamber of shell body 5, shell body 5 and the screw thread of upper press cover 3
Connection.Shell body 5 can effectively ensure that the concordance that spring 6 is moved with lower plug 2.
In order to the opposite direction for ensureing only downward plug 2 effect of spring 6 is moved, the automatic riser of lower plug also includes
Base pressure lid 7, base pressure lid 7 is located at the bottom of spring 6, and base pressure lid 7 is threadedly coupled with shell body 5, and threaded connection is conducive to assembling and tears open
Unload.Base pressure lid 7 limits the axial displacement in 6 one directions of spring, and base pressure lid 7 is detachably fixed with shell body 5 and is connected, outward
Housing 5 is detachably fixed with upper press cover 3 and is connected again, advantageously ensures that the overall stability of the automatic riser of whole lower plug.
