Abstract
The utility model discloses a novel centrifugal casting-type mould tube automatic locking end cover, which is characterized by mainly comprising a slideway, a telescopic spring and a dowel. When a mould tube rotates, the wedge-shaped dowel can move in a dowel hole along the radial direction of the surface of the end cover under the action of a centrifugal force; because of the special shape of the wedge-shaped dowel, with the deepening of the insertion distance of the wedge-shaped dowel in the dowel hole, the dowel can push the end cover compressed tightly along the axial direction, thereby implementing the displacement control of the end cover in the radial direction and the axial direction to achieve the goal of automatic locking. In the rotation process of the mould tube, the spring is still in a state of compression and the end cover cannot get loose, thereby, the safety of the end cover of the form is ensured. The utility model has the advantages that assembly and disassembly are convenient and save labor, the safety is high and the like, thereby, the production efficiency can be greatly improved.
Description
Technical field
The utility model relates to a kind of novel centrifugal casting type tube auto lock end cap and belongs to metallurgy, machinery, electric power, centrifugal casting field, mine.
Background technology
In industrial boiler tube centrifugal casting was produced, the end cap shutoff was adopted at the type tube two ends at present, prevented from that molten steel from splashing to be set in the type tube two ends and to influence tube drawing.The fixing general detachable pin that adopts of end cap, in the production by hand the mode of hammering load and unload, waste time and energy, human factor is bigger.So this end cap fixed form safety coefficient is low, destructive big, inconvenient operation, production efficiency are low.
Summary of the invention
The purpose of this utility model is to propose a kind ofly to overcome above defective, and is safe in utilization, easy to loading and unloading, the type tube end cap of raising the efficiency.A kind of novel centrifugal casting type tube auto lock end cap is characterized in that: mainly be made up of slideway, coil tension spring and wedge stud.A kind of novel centrifugal casting type tube auto lock end cap mainly is to adopt the novel slipway design on end cap.It is characterized in that: auto lock end cap under the centrifugal action that designed slideway produces when the type tube high speed rotating.After type tube rotates, wedge stud is subjected to centrifugal action, can be along the end cap face diameter in pin hole, moving, because the special shape of wedge stud, in pin hole, insert the intensification of distance along with wedge stud, pin can promote end cap and compress vertically, thereby realizes the displacement control of end cap on radial and axial, reaches the purpose of tight lock automatically.In the type tube rotation process, spring still is in compressive state, and end cap can not become flexible, thereby guarantees the security of this form end cap.
For achieving the above object, the utility model has designed special slideway and pin form according to practical working situation.This end cap adopts coil tension spring to connect pin, because the wedge stud lower end is provided with handle, pull handle utilizes the spring force effect that pin is inserted in the type tube pin hole during installation.Only need the hammering pin to loosening state during dismounting, pull handle withdraws from pin from pin hole, unloads bottom end cover.Therefore, the utility model proposes the making and the installation method of auto lock end cap, make new end cap normally to move.Thereby reached the end cap auto lock, convenient use, the purpose of raising the efficiency.
Description of drawings
Fig. 1 installs and uses schematic diagram for end cap.
Fig. 2 is the end cap vertical view.
Specific embodiments
Referring to accompanying drawing 1, end cap 20 is provided with slideway 50, place coil tension spring 30 in the slideway, coil tension spring one end is connected with slideway, one end is connected with wedge stud 70, and the lower end of wedge stud is provided with handle 40, and type tube 10 edges are notch cuttype, which is provided with pin hole 60, its shape size and wedge stud match.Referring to accompanying drawing 2, three slideways are set to the end cap uniform plane, be mutually 120 degree, corresponding type tube edge also is provided with three pin holes equably.
Below the design of wedge shape slideway and pin and the installation and removal of novel centrifugal casting type tube auto lock end cap are analyzed:
The design of 1 slideway
Slideway is the groove that is arranged on the end cap, and its cross section is a rectangle, and the length of slideway should be greater than wedge stud and compression rear spring length sum.For improving the mechanical performance of end cap, the inner surface corner of slideway all makes rounding and handles.
The design of 2 wedge studs
The wedge stud cross section is a rectangle, and its width can not surpass chute width.Wedge stud skewed surface gradient cross conference to wedge stud move radially the generation large drag forces, be unfavorable for the tight lock of end cap; The oblique angle is too small then not to produce enough axial displacement, is unfavorable for the tight lock of end cap equally, so this gradient is consistent with type tube pin hole gradient.
The installation of 3 novel centrifugals casting type tube auto lock end cap
When being installed, end cap at first it is pre-fixed, with handle wedge stud is compacted to end cap edge when pre-fixing, then it is aimed at the pin hole at type tube edge, unclamp handle after wedge stud under the elastic force effect of coil tension spring, be pressed in the pin hole, realized pre-fixing of pin.When the type tube high speed rotating, wedge stud is subjected to centrifugal action, can be along the end cap face diameter in pin hole, moving, because the special shape of wedge stud, in pin hole, insert the intensification of distance along with wedge stud, pin can promote end cap and compress vertically, thereby realizes the displacement control of end cap on radial and axial, reaches the purpose of tight lock automatically.
The dismounting of 4 novel centrifugal foundry furnace type tube auto lock end caps.
During the dismounting end cap, only need the hammering pin to loosening state, pull handle withdraws from pin from pin hole, can unload bottom end cover.A plurality of slideways are set on the end cap plane equably, and slideway links to each other with wedge stud by coil tension spring.
The advantages such as this Novel centrifugal casting furnace tube type tube automatic locking end cover has the safety coefficient height, and is easy to use are to improve centrifugal casting efficient, and laborsaving a kind of invention has promotional value.
