Technical Field

The invention relates to the technical field of casting, in particular to a casting furnace plug leading port device.

Background

The casting furnace utilizes a medium frequency induction furnace on the original equipment used in the casting industry, and the casting is a technological process of smelting metal into liquid meeting certain requirements, pouring the liquid into a casting mold, cooling, solidifying and cleaning to obtain a casting with a preset shape, size and performance. Casting is one of the fundamental processes in the modern manufacturing industry, because of the near shaping, the aim of avoiding machining or little machining is achieved, reducing costs and time to a certain extent. The medium frequency induction furnace can be used for casting more efficiently and more energy-saving, so that the cost is saved and the environment is protected.

But general casting furnace all is equipped with the furnace eye, and the effect of stopper is used for plugging up the furnace eye, prevents that the metal liquid of casting furnace from revealing, and prior art's stopper comprises the stock of a toper chock plug, and during the production was used, aims at the furnace eye with the chock plug, makes strength to the furnace eye extrusion, finally plugs up the furnace eye, but this kind of device operation need exert very big power, and the jam effect is relatively poor, consuming time power, and stifled in-process, the metal liquid that splashes out very easily causes operating personnel's injury moreover.

Disclosure of Invention

The invention aims to provide a casting furnace plug leading port device which is simple to operate, good in plugging effect and capable of safely and quickly plugging a furnace eye.

The invention is realized by the following technical scheme:

the utility model provides a casting furnace stopper draws a mouthful device, includes main shaft, a plurality of connecting plate and stopper, and the connecting plate bottom is rotated and is installed on the main shaft, connects the installation pole between the connecting plate top, connects the end cap on the installation pole, and the action bars is connected outside the connecting plate, and the main shaft is connected on the support, and the support is fixed in the top of casting oven outside stove eye, and the main shaft setting is on the support, and the saddle is located one side of the below casting stove eye of main shaft, and the stopper is installed and is blocked the action bars on the saddle.

Furthermore, the connecting plate is 2, and 2 connecting plates are the symmetry setting, and are stable pleasing to the eye, and the both ends of installation pole are connected with the connecting plate respectively.

Further, the connecting plate with the installation pole junction is equipped with the adjustment tank, the installation pole passes the adjustment tank is connected on the connecting plate, and the installation pole is located in the adjustment tank, conveniently adjusts the position of installation pole according to the circular arc distance between casting stove stopper draw mouthful device and the casting stove eye to realize the regulation of end cap position, make the end cap can with the accurate butt joint of stove eye.

Furthermore, the adjusting groove is of a waist-round structure, the vertical adjustable distance is 100mm, the mounting rod can move up and down to adjust the position, and the adjusting range is larger.

Furthermore, the connecting support rods are connected between the connecting plates, and the connecting plates are more stable and convenient to operate due to the design of the supporting rods.

Further, the supporting rod is connected to the connecting plate through an M8 nut.

Further, the operating rod is connected to the outer part of the connecting plate through an M8 nut.

Furthermore, the plug is of a conical structure, so that the plug can be conveniently plugged into a furnace eye on the casting furnace and is tightly matched with the furnace eye, and molten metal is prevented from splashing in the casting process.

Further, the saddle has T-shaped spout, the stopper passes through T type spout with saddle sliding connection, the T-shaped groove with still be provided with the matched with pinhole on the stopper, the stopper highly be higher than the degree of depth of T type spout, the stopper is installed in the T type spout of saddle, increases the stability of stopper, and the degree of depth that highly is higher than T type spout in spacing hole guarantees that the part that the stopper exceeds T type spout can block the action bars, and is spacing to the action bars, and the stopper passes through bolt fixed position with T type spout, makes the stopper can not retreat, makes the action bars fixed, makes the jam effect better.

The operating rod sets up in the outside of connecting plate, and this design makes the staff need not just block up the furnace eye when the operation, can operate in one side of furnace eye, and it is more convenient and safe to operate.

According to the invention, the limiting block is flexibly arranged, when the operating rod needs to be limited and fixed, the limiting block is arranged in the T-shaped chute of the saddle, the limiting block is fixed through the plug wire, and the limiting block blocks the operating rod, so that the operating rod is fixed.

The casting furnace plug lead port device designed by the invention is made of 45# steel, is hard in texture and is not easy to damage.

The invention has the beneficial effects that:

the invention solves the problem that operators on the traditional casting furnace production line use a long rod with a conical plug head to extrude the furnace eye to block the furnace eye, and the operators are injured due to splashing of molten metal in the blocking process. According to the device, an operator does not need to block the furnace eye directly, the furnace eye can be blocked by pressing the operating rod on one side, and the aim that the operator on a production line can safely operate is fulfilled.
