Detailed Description
As shown in fig. 1-3, a spinneret holder includes a base 110, a gland 120, a spacer 130, and a jacking mechanism 140.
The base 110 has a column 111, the column 111 has a first through hole 112 for inserting the tube 21 of the nozzle 20 downward, and the inner diameter of the first through hole 112 is adapted to the outer diameter of the tube 21. After the tube 21 of the spinneret 20 is inserted downward into the first through hole 112, the loop 22 thereof is just suspended on the top surface of the column 111.
The pressing cover 120 is used for pressing the ring part 22 on the top surface of the column 111, the pressing cover 120 is detachably fixed with the base 110, a second through hole 121 for the punching needle to pass through is formed in the pressing cover 120, the aperture of the second through hole 121 is slightly smaller than that of the first through hole 112, and the center lines of the second through hole 121 and the first through hole 112 are overlapped, so that the pressing cover 120 can press the ring part 22.
The pad 130 is a soft metal pad and is disposed on the jacking mechanism 140.
The jacking mechanism 140 is used to lift the spacer 130 upwards to the bottom surface of the pipe portion 21 and continuously provide support, and the jacking mechanism 140 is fixed on the base 110.
During the use, insert the pipe portion 21 of spinneret 20 downwards into the first through-hole 112 of cylinder 111 earlier, make ring portion 22 hang on the top surface of cylinder 111, and fix gland 120 to base 110, make gland 120 push down ring portion 22, then start climbing mechanism 140, climbing mechanism 140 upwards lifts up gasket 130 to the bottom surface of pipe portion 21 and continuously provides the support, at this moment, the action of punching downwards is carried out to the punching needle, form the location indentation point in the bottom of pipe portion 21, because the continuous support of gasket 130 in the below can prevent that the bottom of pipe portion 21 from producing the deformation, after forming the location indentation point, climbing mechanism 140 descends, the punching needle carries out the action of punching downwards once again and runs through the location indentation point, it is accomplished to punch. Since the location of the indentation point is already equivalent to a non-piercing state, the bottom of the tube 21 is not deformed by the second piercing operation.
In this embodiment, the base 110 includes a bottom plate 113, the bottom of the column 111 has a supporting leg 114, the supporting leg 114 is fixed to the bottom plate 113, and the jacking mechanism 140 is located below the first through hole 112 and fixed to the bottom plate 110.
In this embodiment, the jacking mechanism 140 is a pneumatic jacking pump. The bottom plate 113 is provided with a third through hole 115, the center line of the third through hole 115 coincides with the center line of the first through hole 112, the pump body 141 of the air pressure jacking pump is detachably connected with the third through hole 115, and the gasket 130 is arranged on the jacking head 142 of the air pressure jacking pump 141.
Preferably, the pump body 141 is threadedly coupled to the third through hole 115.
In this embodiment, the diameter of the washer 130 is adapted to the diameter of the bottom surface of the tube portion 21, and the center lines of the two coincide.
In the present embodiment, the first through hole 112, the second through hole 121, and the third through hole 115 are respectively located in the middle of the cylinder 111, the gland 120, and the bottom plate 113.
In the present embodiment, the gland 120 is screw-coupled to the outer circumferential surface of the cylinder 111.
However, those skilled in the art should realize that the above embodiments are only used for illustrating the present invention and not used as a limitation of the present invention, and that the changes and modifications to the above embodiments are within the scope of the appended claims as long as they are within the true spirit of the present invention.
