The utility model discloses in, go up connecting axle motor output shaft, accept instruction rotation operation work when the motor, the also synchronous revolution work of connecting axle, because the helical pitch round pin slides in the centre, rotatory tangent line motion is done to the helical pitch cover, the connecting axle shifts up along the helical pitch tangent line thereupon down, stop rotatory helical pitch cover when the motor and link together with down the connecting axle body along with the gravity power landing, automatic displacement about having rotatory tangent line to do, the action time is short, operate steadily, advantages such as simple operation, and simple structure, easy manufacturing, safety and reliability, the operation maintenance of being convenient for, be applicable to magnesium alloy melt liquid continuous casting, also can use with magnesium alloy melting furnace and magnesium alloy holding furnace cooperation, reach accurate ration notes material.
Description
Technical Field
The utility model relates to a metallurgical casting technical field especially relates to a novel gravity displacement axle from top to bottom.
Background
With the wide application of magnesium alloy materials, the quality requirement of deep processing products of magnesium alloys is higher and higher, the quality of magnesium alloy die castings is difficult to control due to the fact that the key technology of domestic magnesium alloy melting quantitative furnaces is laggard, and in addition, the magnesium alloys are active in chemical properties, easy to oxidize and burn, slightly prone to explosion safety accidents, and further have a plurality of technical barriers in domestic magnesium alloy melting furnace equipment, and especially horizontal quantitative pouring is a pending problem for many years.
The prior method for quantitatively pouring the magnesium alloy has the following defects; the motor always keeps rotating and running when the magnesium alloy is quantitatively poured or not poured, the oxidation protection film is destroyed by ceaselessly stirring, and the liquid level oxidation combustion also occurs: if the horizontal liquid conveying motor stops rotating, liquid can flow back quickly, so that magnesium liquid in a semi-cavity of the liquid conveying pipeline is oxidized and burned to be blocked; because a backflow overcoming method is not good, a fall oblique flow gravity pouring mode is generally adopted in China, otherwise, the whole height of the furnace body needs to be increased, and potential safety hazards in operation and maintenance are brought.
Disclosure of Invention
The utility model aims at providing a not enough and novel gravity displacement axle about can who designs to current technical equipment aims at changing the liquation and passes through the horizontal pipeline pouring, also can overcome the liquid reflux even when long-time stall, guarantees that the infusion pipeline does not produce half cavity, and the pouring time is short and the flow is invariable. The magnesium alloy melt can be accurately and quantitatively poured horizontally, the oxidation and blockage of the magnesium alloy melt in a runner are reduced, and the aims of quickly and quantitatively pouring materials and preventing liquid from flowing back in real time are fulfilled.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a novel gravity displacement axle about can, includes the connecting axle, its characterized in that: the bottom of going up the connecting axle is connected with the helical pitch cover, and the bottom of helical pitch cover is connected with down the connecting axle, the outside of helical pitch cover is installed the smooth round pin of helical pitch.
Preferably, the upper connecting shaft is a motor output shaft, and the upper connecting shaft is connected with the lower connecting shaft through a lead sleeve.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
1. the utility model discloses in, go up connecting axle motor output shaft, accept instruction rotation operation work when the motor, the also synchronous revolution work of connecting axle, because the helical pitch round pin slides in the centre, rotatory tangent line motion is done to the helical pitch cover, the connecting axle shifts up along the helical pitch tangent line thereupon down, stop rotatory helical pitch cover when the motor and link together with down the connecting axle body along with the gravity power landing, automatic displacement about having rotatory tangent line to do, the action time is short, operate steadily, advantages such as simple operation, and simple structure, easy manufacturing, safety and reliability, the operation maintenance of being convenient for, be applicable to magnesium alloy melt liquid continuous casting, also can use with magnesium alloy melting furnace and magnesium alloy holding furnace cooperation, reach accurate ration notes material.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-3, a novel vertical gravity displacement shaft comprises an upper connecting shaft 1, a lead sliding pin 2, a lead sleeve 3 and a lower connecting shaft 4, wherein the bottom of the upper connecting shaft 1 is connected with the lead sleeve 3, the bottom of the lead sleeve 3 is connected with the lower connecting shaft 4, and the lead sliding pin 2 is installed on the outer side of the lead sleeve 3.
Further, the upper connecting shaft 1 is a motor output shaft, the upper connecting shaft 1 is connected with the lower connecting shaft 4 through the lead sleeve 3, when the motor receives an instruction to rotate and operate, the connecting shafts also rotate synchronously, the lead sleeve 3 rotates tangentially to move as the lead sliding pin 2 slides in the middle, the lower connecting shaft 4 moves upwards along the lead tangent line, and when the motor stops rotating, the lead sleeve 3 and the lower connecting shaft 4 are combined together to slide along the gravity.
The working principle is as follows: when the device is used, the upper connecting shaft 1 is arranged on a power output shaft of the motor, when the motor receives an instruction to rotate and operate, the upper connecting shaft 1 also synchronously rotates and operates, as the lead sliding pin 2 slides in the middle, the lead sleeve 3 rotates and moves tangentially, the lower connecting shaft 4 moves upwards along the lead tangent line, and when the motor stops rotating, the lead sleeve 3 and the lower connecting shaft 4 are combined together and slide down along the gravity; the lower connecting shaft 4 is connected with the pump body part of the rotary connecting rod, the lower part of the lower connecting shaft is subjected to resistance of molten liquid during rotation to generate upward power and rotary cutting force, the lead sleeve 3 is passively lifted upwards under the action of the two resultant forces to drive the lower component to open the transfusion channel, and the gravity droops when the rotation is stopped, so that the aim of closing the lower transfusion channel component is fulfilled.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
