Abstract
The utility model provides a cooling device of a feeding barrel of a powder molding press belonging to the mechanical technical field, which resolves the defects in prior art that the rate of finished products can be affected due to the temperature rise of the feeding barrel and the bad operational safety. The cooling device of a feeding barrel of a powder molding press is arranged on the barrel body of the feeding barrel of a powder molding press, wherein the barrel body comprises an outer layer barrel body and an inner layer barrel body arranged in the outer layer barrel body, a gap is formed between the inner layer and the outer layer barrels which forms a cavity, and an inlet and an outlet communicated with the cavity are arranged on the outer layer barrel. The cooling device of a feeding barrel of a powder molding press has the advantages of simple structure, excellent heat radiating effect of the barrel body, high operation stability and the like.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of fine powder press molding machine, particularly adopts the cooling device of the fine powder press molding machine feed cylinder of polytetrafluorethylepowder powder raw material compacting workpiece.
Background technology
Its manufacturing process of workpiece that adopts the die casting of polytetrafluorethylepowder powder raw material to form is simple, manufacturing cost is lower.Therefore, fine powder press molding machine uses in machining more widely.
Usually, fine powder press molding machine comprises hopper and the feed cylinder of connecting with hopper.The polytetrafluorethylepowder powder raw material is delivered in the hopper, and the polytetrafluorethylepowder powder raw material in the hopper enters diel place by feed cylinder again.When fine powder press molding machine worked long hours, feed cylinder rubbed with powder stock for a long time and just makes that the temperature of feed cylinder and powder stock can be along with corresponding improve.
Some fine powder press molding machine can flow smoothly in order to make the powder stock in the feed cylinder, also is provided with agitating device in feed cylinder.Obviously, so just make the temperature increase of feed cylinder and powder stock higher, faster.
Will influence the yield rate of workpiece when usually, the temperature of the powder stock of polytetrafluoroethylene (PTFE) surpasses 30 ℃.Simultaneously, when the operator touches the higher feed cylinder of temperature, also can damage the operator.Therefore, its safety in utilization and less stable.
Summary of the invention
The purpose of this utility model is at existing in prior technology the problems referred to above, and a kind of cooling device of simple in structure, fine powder press molding machine feed cylinder that stability in use is higher is provided.
The purpose of this utility model can realize by following technical proposal: a kind of cooling device of fine powder press molding machine feed cylinder; be arranged on the cylindrical shell place of fine powder press molding machine feed cylinder; it is characterized in that; described cylindrical shell is made up of outer layer barrel and the internal layer cylinder that is positioned at outer layer barrel; has the space between internal layer cylinder and the outer layer barrel; this space forms a cavity, and described outer layer barrel is provided with import and the outlet that communicates with above-mentioned cavity.
The feed cylinder of fine powder press molding machine is arranged on the diel top of fine powder press molding machine, usually, is also connecting a hopper that communicates with it above feed cylinder.The polytetrafluorethylepowder powder raw material that is delivered in the hopper just can enter into diel place through feed cylinder.
Import on the feed cylinder outer layer barrel is connected by pipeline and water pump, and outlet is connected in the pond by pipeline.When fine powder press molding machine was worked, by in the cavity between import injection internal layer cylinder and the outer layer barrel, the water in the cavity was escaped and enter in the pond by outlet pump operation more then with water.Obviously, so just making constantly has water to flow through in the cavity, and cylindrical shell just can dispel the heat by circulating of water, thereby makes that the temperature of fine powder press molding machine cylindrical shell when work can be not too high, and the temperature of polytetrafluorethylepowder powder raw material can be not too high yet.
In the cooling device of above-mentioned fine powder press molding machine feed cylinder, described outer layer barrel is cylindric with internal layer cylinder and both coaxial settings.Such structure processing and manufacturing is comparatively easy.
In the cooling device of above-mentioned fine powder press molding machine feed cylinder, described import is positioned at the top of outer layer barrel, and described outlet is positioned at the bottom of outer layer barrel.Such structure makes water to circulate in cavity more fully.
Compared with prior art, the cooling device of this fine powder press molding machine feed cylinder just is made as sandwich with cylindrical shell, and makes when fine powder press molding machine is worked in the cavity between internal layer cylinder and the outer layer barrel and have water to circulate.Obviously, it is not only simple in structure, but also makes that the radiating effect of cylindrical shell is better.
Simultaneously, the temperature of the cylindrical shell of feed cylinder can be not too high, the yield rate when so not only having improved fine powder press molding machine compacting workpiece, and also safety in utilization is also higher.

The specific embodiment
As depicted in figs. 1 and 2, the cooling device of this fine powder press molding machine feed cylinder is provided with the feed cylinder place of fine powder press molding machine.
As shown in Figure 3, feed cylinder is one and is cylindrical shell 1 cylindraceous that cylindrical shell 1 is made up of outer layer barrel 2 and internal layer cylinder 3.Internal layer cylinder 3 is positioned at outer layer barrel 2, and has the space between internal layer cylinder 3 and the outer layer barrel 2, and this space forms a cavity 11.In the present embodiment, internal layer cylinder 3 and outer layer barrel 2 are cylindric, and internal layer cylinder 3 is coaxial settings with outer layer barrel 2.
As shown in Figure 2, outer layer barrel 2 is provided with import 21 and outlet 22, and import 21 is joined by pipeline and water pump, and go out 22 and be connected in the pond by pipeline, and import 21 and export 22 and all communicate with above-mentioned cavity 11.In the present embodiment, import 21 is positioned at the top of outer layer barrel 2, and outlet 22 is positioned at the bottom of outer layer barrel 2.
Usually, the cylindrical shell 1 of feed cylinder is positioned at diel 5 places of fine powder press molding machine, is also connecting a hopper that communicates with it 4 on the top of cylindrical shell 1, sees shown in Figure 1.The polytetrafluorethylepowder powder raw material that is delivered in the hopper 4 just can enter diel 5 places by feed cylinder.
Fine powder press molding machine is when work, and water enters cavity 11 by import 21, and the water in the cavity 11 discharges by going out 22 again.Water just circulated in cavity 11 when like this, fine powder press molding machine was worked.Obviously, under the effect of this cooling device, can dispel the heat, that is to say that the water by circulating at cavity 11 dispels the heat to cylindrical shell 1, raise with the temperature that prevents cylindrical shell 1 and powder stock to cylindrical shell 1.
