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 can be realized when an explosive column is extruded to different heights, 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
Technical field
The invention belongs to hydraulic machinery manufacturing technology field, particularly relate to a kind of accurate digital control bidirectional press automatic vacuum-pumping apparatus.
Background technology
At present, along with developing rapidly of China's military industry field, the increasing large-tonnage accurate digital control bidirectional hydraulic press that uses in the production technique of explosive column.The compacting of explosive column is put into medicinal powder after mould when the automatic charging device of hydropress in producing, and produces bubble for fear of powder column in pressing process, affects the compacting quality of powder column, conventionally need to vacuumize operation to the medicinal powder of mould.Tradition vacuum extractor needs manually vacuumizing joint to be received on mould, then the medicinal powder in mould is carried out to disposable vacuumizing.Adopt above-mentioned vacuum extractor cannot realize explosive column and in the time being squeezed to different heights, carry out automatic vacuum, be not only difficult to ensure workpiece vacuum tightness in mould closed cavities, and can not meet the needs of full-automatic explosive column production line.
Summary of the invention
The present invention for solve the technical problem existing in known technology provide a kind of simple in structure, can realize the accurate digital control bidirectional press automatic vacuum-pumping apparatus that explosive column carries out automatic vacuum and can ensure workpiece vacuum tightness in mould closed cavities in the time being squeezed to different heights.
The technical scheme that the present invention takes for the technical problem existing in solution known technology is:
Accurate digital control bidirectional press automatic vacuum-pumping apparatus, 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 in vacuumize dish by vacuum-lines with vacuumize pumping plant and be communicated with.
The present invention 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 mould is provided with sealing-ring.
Advantage and positively effect that the present invention has are: because the present invention adopts technique scheme, by tele-control system, this automatic vacuum-pumping apparatus is controlled, and promote to vacuumize dish by hold-down cylinder and realize automatic butt mould, can realize explosive column carries out automatic vacuum and can ensure workpiece vacuum tightness in mould closed cavities in the time 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.

In 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 invention, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, accurate digital control bidirectional press automatic vacuum-pumping apparatus, comprises the hold-down cylinder 4 affixed with press top shoe, and the other end of described hold-down cylinder is that piston rod is connected with and vacuumizes dish 6, described in vacuumize dish by vacuum-lines 7 with vacuumize pumping plant and be communicated with.
In the present embodiment, described in vacuumize pumping plant and comprise vacuum pumping pump 9, be arranged on the hay tank 10 of vacuum pumping pump one side and be arranged on the cooling tank 11 of vacuum pumping pump opposite side.
Described vacuumize dish with press upper punch 1 contact site be provided with sealing-ring 5, described in vacuumize dish with mould between be provided with sealing-ring.
Described press upper punch 1 is connected with press top shoe, and press lower punch 3 lower ends are connected with press sliding block.
Principle of work of the present invention is:
After the medicinal powder in mould 2 smooths by powder flattening device, vacuumize dish 6 with upper punch 1 DL synchronization, entering before sealing die cavity at upper punch, vacuumize dish and fit and seal with the die end face of mould.Now, by tele-control system sender, vacuum pumping pump 9 is received after instruction, and to starting to vacuumize work in mould medicinal powder closed cavities, this process also can be carried out (when compacting, hold-down cylinder is passive returns) in compacting.In the time that the vacuum tightness in medicinal powder 8 closed cavitieies reaches set(ting)value, vacuum pumping pump quits work, and upper punch 1 continues the suppression process of descending beginning powder column.
