Abstract

The utility model relates to an automatic vacuumizing device of a precision numerical control two-way hydraulic press. The device is characterized by comprising a compaction cylinder fixedly connected with a press sliding bock, wherein the other end of the compaction cylinder is connected with a vacuumizing plate, and the vacuumizing plate is communicated with a vacuumizing pump station through a vacuum pipeline. The device has the advantages that automatic vacuumizing when an explosive column is extruded to different heights can be realized, the vacuum degree of a workpiece in a closed cavity of a mold can be ensured, bubbles produced in the pressing process of the explosive column can be reduced, the quality of the explosive column product is improved, and the working efficiency can also be improved.

Description

Accurate digital control bidirectional hydraulic machine automatic vacuum device
Technical field
The utility model belongs to hydraulic machinery manufacturing technology field, particularly relates to the two-way press automatic vacuum of a kind of accurate digital control device.
Background technology
At present, along with developing rapidly of China's military industry field, the increasing large-tonnage accurate digital control bidirectional hydraulic machine that uses in the production technique of explosive column.The compacting of explosive column after the automatic charging device of hydropress is put into mould with medicinal powder, produces bubble for fear of powder column in pressing process in producing, and influences the compacting quality of powder column, need vacuumize operation to the medicinal powder of mould usually.The tradition vacuum extractor needs manually vacuumizing joint to be received on the mould, then the medicinal powder in the mould is carried out disposable vacuumizing.Adopt above-mentioned vacuum extractor can't realize that explosive column carries out automatic vacuum when being squeezed to different heights, not only be difficult to guarantee workpiece vacuum tightness in the mould closed cavities, and can not satisfy the needs of full-automatic explosive column production line.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, can realize that explosive column carries out automatic vacuum and can guarantee the two-way press automatic vacuum of the accurate digital control device of workpiece vacuum tightness in the mould closed cavities when being squeezed to different heights.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
The two-way press automatic vacuum of accurate digital control device comprises the hold-down cylinder affixed with press slide, and the other end of described hold-down cylinder is connected with and vacuumizes dish, described vacuumize dish by vacuum-lines with vacuumize pumping plant and be communicated with.
The utility model can also adopt following technical scheme:
The described pumping plant that vacuumizes comprises vacuum pumping pump, is arranged on the hay tank of vacuum pumping pump one side and is arranged on the cooling tank of vacuum pumping pump opposite side.
The described dish that vacuumizes is provided with sealing-ring with press upper punch contact site.
Described vacuumizing between dish and the mould is provided with sealing-ring.
Advantage and the positively effect that the utlity model has are: because the utility model adopts technique scheme, by tele-control system this automatic vacuum device is controlled, and promote to vacuumize dish by hold-down cylinder and realize the automatic butt mould, can realize that explosive column carries out automatic vacuum and can guarantee workpiece vacuum tightness in the mould closed cavities when being squeezed to different heights, not only can reduce bubble, raising powder column quality product that powder column occurs in pressing process, but also can increase work efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, upper punch; 2, mould; 3, lower punch; 4, hold-down cylinder; 5, sealing-ring; 6, vacuumize dish; 7, vacuum-lines; 8, medicinal powder; 9, vacuum pumping pump; 10, hay tank; 11, cooling tank.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, the two-way press automatic vacuum of accurate digital control device comprises the hold-down cylinder 4 affixed with the press top shoe, and the other end of described hold-down cylinder is that piston rod is connected with and vacuumizes dish 6, described vacuumize dish by vacuum-lines 7 with vacuumize pumping plant and be communicated with.
In the present embodiment, the described pumping plant that vacuumizes comprises vacuum pumping pump 9, is arranged on the hay tank 10 of vacuum pumping pump one side and is arranged on the cooling tank 11 of vacuum pumping pump opposite side.
The described dish that vacuumizes is provided with sealing-ring 5 with press upper punch 1 contact site, and described vacuumizing between dish and the mould is provided with sealing-ring.
Described press upper punch 1 is connected with the press top shoe, and press lower punch 3 lower ends are connected with the press sliding block.
Principle of work of the present utility model is:
After the medicinal powder in the mould 2 smooths by the powder flattening device, vacuumize dish 6 with upper punch 1 DL synchronization, before upper punch is entering the sealing die cavity, vacuumize dish and fit and sealing with the die end face of mould.At this moment, by the tele-control system sender, after vacuum pumping pump 9 was received instruction, to beginning the work of vacuumizing in the mould medicinal powder closed cavities, this process also can be carried out (hold-down cylinder is passive during compacting returns) in compacting.When the vacuum tightness in medicinal powder 8 closed cavitieies reached set(ting)value, vacuum pumping pump quit work, and upper punch 1 continues the suppression process of descending beginning powder column.
