Embodiment Construction

[0008] The present invention will be further described below in conjunction with accompanying drawing.

[0009] The structure of the present invention is as figure 1 As shown, it includes a forged female part 1 and a male part 2. The surface of the female part 1 has a depression, and the surface of the male part 2 has a protrusion that matches the depression on the surface of the female part 1. The joint between the protrusion and the depression is paved with Rubber film sheath layer 3.

[0010] The non-contact surface of the female part 1 and the male part is provided with a fixed lock, which facilitates the fixing of the sealing part and the equipment to be sealed.

[0011] When the present invention is used, the female part and the male part are respectively fixed at the places to be sealed, and when fixing is required, the protrusions and the recesses of the female part and the male part are controlled to fit together to realize sealing. If the rubber film sheath layer a...

Abstract

The invention provides a combined forged sealing piece. The combined forged sealing piece comprises a negative piece and a positive piece which are molded through forging, wherein indentations exist in the surface of the negative piece, and bulges matched with the indentations in the surface of the negative piece exist on the surface of the positive piece; a rubber film restrictive coating is laid in the combination position of the depressions and the bulges. According to the combined forging sealing piece disclosed by the invention, a forging piece used as a substrate is matched with an interchangeable rubber layer to perform sealing, so that the sealing effect is good, and the rubber layer is easy to change.

Description

technical field [0001] The invention relates to the field of forged parts, in particular to a combined forged sealing part. Background technique [0002] Seals are materials or parts that prevent fluid or solid particles from leaking from adjacent joint surfaces and prevent external impurities such as dust and moisture from invading the internal parts of the machine. Although the seal is small, its function makes it a basic component and accessory in the main industries of the national economy such as national defense, chemical industry, petroleum, coal, transportation and machinery manufacturing, and occupies a very important position in the development of the national economy. The current rubber seals have problems such as wear and tear, easy aging, and troublesome replacement of the entire part. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a combined forged seal, which uses the forged part as the bas...
