Abstract

The invention provides a novel automatic locking end cover of a centrifugal tube casting die, and belongs to the field of metallurgy centrifugal casting. The novel end cover comprises a cover plate and a pin with a stretching spring, and is fixed by utilizing acting force of the spring when mounting. When the die is operated, automatic tight locking is realized through centrifugal affect, assembling and disassembling are facilitated, security is fine, and producing efficiency can be improved greatly.

Description

A kind of novel centrifugal casting pipe die automatic locking end cover

Technical field

The present invention relates to a kind of centrifugal casting furnace pipe die automatic locking end cover and belong to metallurgical centrifugal casting field.

Background technology

In centrifugal casting technique, the end cap shutoff is adopted at boiler tube mould two, prevents that molten metal splashing is set in the mould two ends and affects tube drawing at present.The fixing at present general detachable pin that adopts of end cap loads and unloads with the mode of beaing in the production, and pipe die is had very macrolesion, and owing to beaing vibration, also may destroy the balance of pipe die and affects product quality.So utilize pin fixedly end cap have that safety coefficient is low, destructive large, inconvenient operation, affect the shortcoming such as production efficiency.Centrifugal casting furnace pipe die end cap mainly adopts the detachable pin to fix at present, needs in the production process repeatedly to beat to load and unload, and not only pipe die is had damage, and loses time, and efficient is lower, and also existence in service is certain dangerous.

Summary of the invention

The objective of the invention is to propose the above defective of a kind of customer service, use safety, easy to loading and unloading, a kind of novel centrifugal casting pipe die automatic locking end cover of raising the efficiency, owing to can produce very large centrifugal action during the pipe die high speed rotating, as long as pin pre-fixes, along with the pipe die rotation just can be more and more tighter.

The present invention is achieved through the following technical solutions goal of the invention:

A kind of novel centrifugal casting pipe die automatic locking end cover comprises pipe die, is provided with end cap in the end of described pipe die, one circle of end cap periphery is die wall, one end of coil tension spring is fixed on the described end cap, and pin is connected on the coil tension spring, and the interior survey of described pipe die has molten metal.

Pin is provided with handle described in the present invention.

Beneficial effect:

This pipe die automatic locking end cover cost is low, and is easy to operate, can enhance productivity and safety coefficient.

Description of drawings

Fig. 1 is that end cap is installed and used schematic diagram.

Fig. 2 is the end cap top view.

Specific embodiments

A kind of novel centrifugal casting pipe die automatic locking end cover, pipe die 10 is set, be provided with end cap 40 in the end of pipe die 10, one circle of end cap 40 peripheries is die wall 30, one end of coil tension spring 50 is fixed on the described end cap 40, pin 60 is connected on the coil tension spring 50, and the interior survey of pipe die 10 has molten metal (20), and pin 60 is provided with handle 70.

With reference to figure 1 and Fig. 2, an end of coil tension spring 50 is fixed on the end cap 40, and pin 60 is connected on the coil tension spring 50.When pre-fixing, with handle 70 pin 60 is compacted in end cap 40 edges, end cap is filled on the pipe die 10, unclamp handle 70 after aiming at the draw-in groove on the die wall 30, pin 60 in draw-in groove, has been realized pre-fixing of end cap 40 by bullet.When the beginning spun casting, the pipe die high speed rotating, pin 60 is outwards moved by centrifugal action, and more card is tighter in the draw-in groove on die wall 30, thus the locking end cap prevents that molten metal 20 from splashing.The present invention adopts coil tension spring to connect pin, utilizes the spring force effect that pin is pre-fixed on the die wall draw-in groove during installation, and is convenient and swift.After pipe die rotated, wedge stud was subject to centrifugal action, and more card is tighter in draw-in groove, and spring is in compressive state always, and end cap can not produce loosening, thereby guarantees the safe moulding of molten metal.

Claims

1. a novel centrifugal is cast the pipe die automatic locking end cover, it is characterized in that: comprise pipe die (10), be provided with end cap (40) in the end of described pipe die (10), a circle of end cap (40) periphery is die wall (30),

One end of coil tension spring (50) is fixed on the described end cap (40), and pin (60) is connected on the coil tension spring (50), and the interior survey of described pipe die (10) has molten metal (20).
