Abstract

portable annular seal gasket forming device, including the circumscribed cutter and the inscribe cutter of matched with, circumscribed cutter coaxial relatively fixed is in the periphery of inscribe cutter, and circumscribed cutter and inscribe cutter's cutting tip clearance is at a distance from constituting the annular shaping space, and ejecting sleeve is located the annular shaping space and removes the cooperation, and ejecting telescopic inner end has reset spring, forms seal gasket ejection mechanism the utility model discloses a rational in infrastructure, the cutting tip clearance that utilizes interior, circumscribed cutter is at a distance from the annular shaping space that constitutes, only need to be with interior, circumscribed cutter play the pushing down can easily cut the shaping on flexible sealing sheet and go out regular annular seal gasket, and it is very convenient to use the operation, overall structure is compact, light in weight, portable, and the on-the-site preparation is efficient.

Description

Portable annular sealing gasket forming device

The technical field is that the utility model relates to kinds of on-the-spot production tools, in particular to a forming device of an annular sealing gasket.

In the background technology, various sealing gaskets are often needed in the installation and debugging sites of production equipment such as a valve , a pipeline and the like, and nonstandard sealing gaskets are sometimes needed.

Aiming at the defects of the prior art, the utility model provides portable annular sealing gasket forming devices with convenient use.

The utility model discloses a matched with circumscribed cutter and inscribe cutter, circumscribed cutter coaxial relatively fixed are in inscribe cutter's periphery, and circumscribed cutter and inscribe cutter's cutting tip clearance is at a distance from constituting the annular forming space, and ejecting sleeve is arranged in the annular forming space and removes the cooperation, and ejecting telescopic inner end has reset spring, forms seal gasket ejection mechanism.

The utility model discloses a rational in infrastructure, the annular shaping space of utilizing the cutting tip clearance of inside and outside cutter apart from the constitution only needs to play inside and outside cutter and pushes down can easily cut the shaping on flexible sealing sheet and go out regular annular seal gasket, and it is very convenient to use the operation, and overall structure is compact, light in weight, portable, and on-the-spot preparation is efficient.

The present invention will be further described in with reference to the accompanying drawings and examples.

Description of the drawings: fig. 1 is a schematic diagram of the main structure of the embodiment.

Fig. 2 is a schematic view of the cutting operation state of fig. 1.

The specific implementation mode is that as shown in fig. 1, an external cutter 1 is coaxially and relatively fixed on the periphery of an internal cutter 2, a gap between cutting end parts of the external cutter 1 and the internal cutter 2 forms an annular forming space, an ejection sleeve 3 is positioned in the annular forming space and movably matched, and a return spring 4 is arranged at the inner end of the ejection sleeve 3 to form a sealing gasket ejection mechanism.

When the sealing gasket is manufactured, as shown in fig. 2, the outer end part of an ejection sleeve 3 of the device is placed on a flexible sealing sheet 8, an inner cutter 2 is pressed downwards, an outer cutter 1 is synchronously pressed downwards, a return spring 4 is compressed, and the ejection sleeve 3 moves upwards relatively. The cutting ends of the external cutter 1 and the internal cutter 2 are contacted with the flexible sealing sheet 8 and then are pressed downwards and cut, and the annular sealing gasket 9 can be cut and formed in the annular forming space of the device. The downward pressure is removed, the return spring 4 is elastically restored, the ejection sleeve 3 is ejected outwards, the annular sealing gasket 9 can be ejected out of the annular forming space in a demoulding way, and the whole operation and use process is easy and convenient.
