Abstract
The utility model relates to an automatic heightening nozzle, belonging to the technical field of fast forming. The automatic heightening nozzle comprises a nozzle which can move up and down, and is characterized in that the nozzle is fixed with an elastic mechanism which pulls the nozzle to move up and down by the elasticity of an elastic part thereof. When the inside of the nozzle has fed materials, the nozzle can automatically move downward, and when the inside of the nozzle does not have fed materials, the nozzle can automatically move upward. The automatic heightening nozzle has very simple structure, practicability, convenience, safety and reliability.
Description
Technical field
The utility model belongs to the RP technique field, particularly relates to heightening shower nozzle automatically.
Background technology
The basic principle of rapid forming system is: connecting gear is sent into the silk material in the liquefier of shower nozzle fusing and melted material is extruded from the nozzle than minor diameter, form material and pile up the path, under the control of computer, realize fast shaping technology based on melt extruded stack shaping principle.Because the melt extruded that needs to realize multiple material is piled up, in general rapid forming system, (see Fig. 1, Fig. 2), for realizing the continuity of forming technology, each shower nozzle 1 all has a controller 2-when sending material 3 to and send shower nozzle 1 to, motion down moves by the signal of telecommunication driving shower nozzle 1 of controller 2, extrude the fusion silk, when sending material 3 to and stop to send shower nozzle 1 to, motion up moves by the signal of telecommunication driving shower nozzle 1 of controller 2, because the material category of fusion is more, includes a plurality of shower nozzles in the rapid forming system, then the number of this controller is also a lot, has increased very big cost to rapid forming system.
The utility model content
At the defective in the above-mentioned field, the utility model provides heightens shower nozzle automatically, and structure is very simple, and when sending material in shower nozzle, shower nozzle is down motion automatically, and when nothing in the shower nozzle was sent material to, shower nozzle moved upward automatically.
Automatically heighten shower nozzle, comprise the upper and lower mobile shower nozzle of an energy, it is characterized in that: described shower nozzle is fixed with the elastic mechanism that moves up and down by its elastomeric element elastic force pulling shower nozzle.
Described elastic mechanism comprises elastomeric element and the fixture of fixing this elastomeric element.
Described elastomeric element is a spring.
Described spring is extension spring or stage clip, and the upper end of described extension spring is fixed on the fixture, and the lower end is fixed on the shower nozzle; The lower end of described stage clip is fixed on the fixture, and the upper end is fixed on the shower nozzle
Described shower nozzle below is provided with the lower limit that stops shower nozzle to move downward.
Described shower nozzle top is provided with the upper limit that stops shower nozzle to move upward.
The fixing elastic mechanism that moves up and down by the elastic force pulling shower nozzle of elastomeric element of shower nozzle, when in the shower nozzle but such the sending material to or though the plastics silk arranged but the plastics silk is not applied power when extruding downwards of plastics silk, shower nozzle and elastomeric element are kept a kind of balance, when send in the shower nozzle as the plastics silk send material to the time, because the effect of wire feeding force, the plastics silk is extruded from shower nozzle and is had downward speed, this power is big more, the extruded velocity of plastics silk is big more, being equivalent to the shower nozzle deadweight increases, thereby driving shower nozzle down moves, wire feeding force and elastomeric element are stretched or compressed, when the wire feeding force of a certain fixed size and elastomeric element and shower nozzle deadweight reached equilbrium position (lower limit), the plastics silk was at the uniform velocity extruded a material.When not having in the shower nozzle when sending material to and extruding, the shower nozzle deadweight reduces, and gets back to home position (upper limit) under the traction of elastic telescopic body.Preferred resilient members is a spring.
For guaranteeing the accuracy of nozzle position, fixing upper limit and lower limit can be set, the deflection of spring is subjected to upper and lower spacing control, and motional inertia do not cause between the shower nozzle motor area excessively yet, makes system more reliable, safety.

The specific embodiment
As shown in Figure 3, Figure 4, the utility model is heightened shower nozzle automatically, comprises the upper and lower mobile shower nozzle 1 of an energy, it is characterized in that: described shower nozzle 1 is fixed with the elastic mechanism that moves up and down by its elastomeric element elastic force pulling shower nozzle.When in the shower nozzle but such the sending material 3 to or though the plastics silk arranged but the plastics silk is not applied power when extruding downwards of plastics silk, shower nozzle and elastomeric element are kept a kind of balance, when send in the shower nozzle as the plastics silk send material 3 to the time, because the effect of wire feeding force, the plastics silk is extruded from shower nozzle and is had downward speed, this power is big more, the extruded velocity of plastics silk is big more, being equivalent to the shower nozzle deadweight increases, thereby driving shower nozzle down moves, wire feeding force and elastomeric element are stretched or compressed, and when the wire feeding force of a certain fixed size and elastomeric element and shower nozzle deadweight reached equilbrium position (lower limit), the plastics silk was at the uniform velocity extruded a material.When not having in the shower nozzle when sending material to and extruding, the shower nozzle deadweight reduces, and gets back to home position (upper limit) under the traction of elastic telescopic body.
Described elastic mechanism comprises elastomeric element and the fixture of fixing this elastomeric element, and described elastomeric element is a spring 4, and described spring 4 is extension spring or stage clip, and the upper end of described extension spring is fixed on the fixture, and the lower end is fixed on the shower nozzle 1; The lower end of described stage clip is fixed on the fixture, and the upper end is fixed on the shower nozzle 1.
For guaranteeing the accuracy of nozzle position, fixing upper limit 5 and lower limit 6 can be set, when shower nozzle 1 when being issued to lower limit 6, shower nozzle 1 can down not move again, when shower nozzle 1 resetted, shower nozzle is got back to upper limit 5 can be owing to inertia up motion again, and spring 4 deflections are subjected to upper and lower spacing control, make system more reliable, safety.
