Abstract

The utility model discloses a powder forming hydropress which comprises a rack, and an upper template (1), a female template (2), a middle fixed template (3) and a fixed template (4) which are sequentially arranged on the rack from top to bottom, wherein the female template (2) is connected with a top cylinder (8) through a guide pillar, the two sides of the lower end face of the female template (2) are provided with small hydraulic oil cylinders (11) in the horizontal direction, and the end parts of the small hydraulic oil cylinders (11) are connected with limiting blocks (6). In the process of pressing, the small hydraulic oil cylinders are ejected so as to play a role of fixed limiting, when a workpiece in a female die is required to be demolded, the small hydraulic oil cylinders are retreated, and the top cylinder connected with the female template pulls the female template to subside, in such a way, the workpiece in the female template is ejected out of a female die cavity by a fixed lower puncher pin so as to complete a demolding process. By using the powder forming hydropress disclosed by the utility model, the pressing of stepped workpieces can be completed once, and the demolding is convenient.

Description

A kind of hydraulic press for powder formation
Technical field
The present invention relates to a kind of hydraulic press, relate in particular to a kind of hydraulic press for powder formation.
Background technology
Hydraulic press for powder formation is used for dusty material is pressed into pie; When the step-like metallic article of compacting, traditional method is through hydraulic press for powder formation dusty material to be pressed into pie, carries out the machining cutting again; Production efficiency is low; And the clout after the cutting can't re-use, and causes waste material, has improved production cost.A kind of hydraulic press for powder formation is also arranged, and it comprises the upper punch that is connected with little hydraulic jack, is fixed on the low punch on the frame; And the negative template between the last low punch; Be connected with former in the negative template, the inner chamber of former is directly processed stepped, once can be through the effect of last low punch and former with powder pressing forming; But because former is step-like; Therefore former and negative template thereof can receive downward impulsive force when upper punch pressed down, and must be provided with one fixing spacingly in the bottom of negative template, were used to process negative template.It exists shortcoming to be: low punch is for fixing, and negative template can't move down down in fixing spacing effect, and the workpiece that causes suppressing completion can't automatic demoulding, and very inconvenience influences production efficiency.
Summary of the invention
The technical problem that the present invention will solve provides a kind of hydraulic press for powder formation of can a step-like pulverulent product of compression moulding and being convenient in demoulding.
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of hydraulic press for powder formation, comprise frame, and the cope match-plate pattern that sets gradually from top to bottom on the frame, negative template, middle fixed form, fixed form; Said cope match-plate pattern is provided with central cylinder, and the fixed form below is provided with takes blame for others; Be connected with upper punch on the described central cylinder, be fixed with the low punch of fixed form in passing on the fixed form; Described negative template is connected with taking blame for others through guide pillar, and is provided with the little hydraulic jack of horizontal direction in the both sides, lower surface of described negative template; The end of described little hydraulic jack is connected with limited block.
Beneficial effect of the present invention is: adopt the hydraulic press for powder formation of this structure, can once accomplish the compacting of stepped workpiece, and be convenient in demoulding.
Description of drawings
Fig. 1 is the mould bases structural representation of a kind of hydraulic press for powder formation of the present invention.
Marginal data: cope match-plate pattern 1, negative template 2, middle fixed form 3, fixed form 4, central cylinder 5, limited block 6, former 7, take blame for others 8, guide pillar 9, lower bolster 10, little hydraulic jack 11.
The specific embodiment
As shown in Figure 1; The present invention designs a kind of hydraulic press for powder formation; It comprises on the mould bases cope match-plate pattern 1, middle fixed form 3 and fixed form 4 from top to bottom, central cylinder 5 is housed on the cope match-plate pattern 1, the top of this central cylinder 5 is connected with upper punch; The center fixation of fixed form 4 has the low punch that passes middle fixed form 3, and its below is provided with takes blame for others 8.
Negative template 2 is located between cope match-plate pattern 1 and the middle fixed form 3, and it 8 is connected with taking blame for others through fore-set 9 and lower bolster 10.Little hydraulic jack 11 is located at the both sides of negative template 2, the top of middle fixed form 3, and its piston rod end is connected with limited block 6.When the piston rod of little hydraulic jack 11 ejected, limited block 6 was arranged in the top of fixed form 3, and when piston rod was retreated, limited block 6 was arranged in a side of fixed form 3.
Former 7 is housed in the negative template 2, and the inner chamber of this former 7 is stepped, during compacting; Taking blame for others 8 promotes negative templates 2 and former 7 rises, and makes former 7 and low punch constitute a cavity, in changing cavity, adds powder; Simultaneously, the piston rod of little hydraulic jack 11 ejects, and limited block 6 is placed the top of fixed form 3; Like this; When upper punch was pressed into the ladder cavity of former 7 downwards, the limited block 6 of negative template 2 lower surfaces was against on the middle fixed form 3 of its below, bears the impact of upper punch to former 7 and negative template 2.After compacting was accomplished, the piston rod of little hydraulic jack 11 was retreated, a side of fixed head 3 during limited block 6 retreats into, and the 8 pulling negative templates 2 of taking blame for others sink, and make workpiece in the former 7 in the effect realization demoulding down of former that sinks 7 and fixing indefinite low punch.

Claims (2)

1. hydraulic press for powder formation; Comprise frame; And the cope match-plate pattern that sets gradually from top to bottom on the frame (1), negative template (2), middle fixed form (3), fixed form (4); It is characterized by: cope match-plate pattern (1) is provided with central cylinder (5), and fixed form (4) below is provided with take blame for others (8); Central cylinder is connected with upper punch on (5); Fixed form is fixed with the low punch that passes middle fixed form (3) on (4); Negative template (2) is connected with take blame for others (8) through guide pillar, and is provided with the little hydraulic jack (11) of horizontal direction in the both sides, lower surface of described negative template (2).
2. a kind of hydraulic press for powder formation according to claim 1 is characterized by: the end of said little hydraulic jack (11) is connected with limited block (6).
