Abstract
A copper-clad pad comprises a nonmetallic filler, wherein the nonmetallic filler is in a strip shape; the non-metal filler is filled in the groove, the second copper bar covers the non-metal filler, and the two side edges of the first copper bar are folded inwards to form folded edges so as to cover and tightly press the edges of the second copper bar, so that the non-metal filler is wrapped in the first copper bar and the second copper bar to form a copper cladding belt; the copper-clad belt is welded in a butt joint mode at the head and the tail to form an annular copper-clad pad with upper and lower surfaces.
Description
Technical Field
The utility model relates to a copper-clad pad.
Background
A metal-clad mat is a mat in which a non-metallic filler (e.g., graphite) is wrapped in metal, and is annular in shape. For example CN 201884647U discloses a metal-clad gasket as an annular member consisting of an outer metal-clad layer and an inner filler layer. The metal coating layer can be made of stainless steel, nickel, titanium, copper, iron, aluminum or lead, wherein any one of the metal materials can be selected, and 300 series stainless steel is preferably selected in the stainless steel, for example: 304. 316, 321, etc. The filling layer is made of any one of graphite, polytetrafluoroethylene, asbestos or ceramic. The metal wrapping layer is divided into two parts, namely an annular metal groove and a baffle plate, the filling layer is firstly arranged in the annular metal groove, and then the baffle plate is pressed at the opening through pressure equipment to manufacture the gasket with an integrated structure.
The annular metal groove and the baffle of the metal coating layer of the existing metal coating pad are all integrated annular pieces, and the filling layer is also integrated annular pieces. The method adopted in the process of forming the annular metal groove, the annular baffle plate and the annular filling layer is to punch out annular parts on the metal plate and the filling plate, and the residual materials after punching become waste materials, so that the waste is extremely serious.
Disclosure of Invention
In order to overcome the defects of the prior copper cladding pad, the utility model provides the copper cladding pad, and the production raw materials can be greatly saved based on the structure of the copper cladding pad.
The technical scheme for solving the technical problems is as follows: a copper-clad pad comprises a nonmetallic filler, wherein the nonmetallic filler is in a strip shape;
The non-metal filler is filled in the groove, the second copper bar covers the non-metal filler, and the two side edges of the first copper bar are folded inwards to form folded edges so as to cover and tightly press the edges of the second copper bar, so that the non-metal filler is wrapped in the first copper bar and the second copper bar to form a copper cladding belt;
the copper-clad belt is welded in a butt joint mode at the head and the tail to form an annular copper-clad pad with upper and lower surfaces.
Further, the nonmetallic filler has several layers.
Further, two side edges of the second copper bar are respectively propped against the inner sides of the two side edges of the first copper bar.
The utility model has the beneficial effects that: the first copper bar and the second copper bar are both strip-shaped, and the nonmetallic filler is also strip-shaped, so that only strip-shaped raw materials are needed in production, the raw materials are not needed to be obtained through stamping, the generation of waste materials can be greatly reduced, and the production cost is greatly saved.
Drawings
Fig. 1 is a front plan view of the present utility model.
Fig. 2 is a cross-sectional view taken along A-A of fig. 1.
Description of the embodiments
The utility model is described in further detail below with reference to the drawings and the detailed description.
Referring to fig. 1 and 2, a copper-clad pad includes a non-metal filler 3, wherein the non-metal filler 3 is in a strip shape.
The novel copper-clad steel wire rod further comprises a first copper bar 1 and a second copper bar 2, wherein two sides of the first copper bar 1 are bent upwards to form a groove after being laterally bent, a nonmetal filler 3 is filled in the groove, the second copper bar 2 is covered above the nonmetal filler 3, two side edges of the first copper bar 1 are folded inwards to form a folded edge, the edge of the second copper bar 2 is covered and tightly pressed, and accordingly the nonmetal filler 3 is wrapped in the first copper bar 1 and the second copper bar 2 to form a copper-clad steel wire rod.
The copper-clad belt is welded in a butt joint mode at the head end and the tail end to form an annular copper-clad pad with upper and lower surfaces, a welding line 4 is formed at a welding position, and polishing treatment is preferably carried out on the welding line 4. The ring shape having upper and lower surfaces means that the copper clad laminate is not looped into a ring having inner and outer surfaces but into a flat ring having upper and lower surfaces when looped into a ring shape.
In one embodiment, the nonmetallic filler 3 has several layers, and the nonmetallic filler 3 is usually graphite, but may be other nonmetallic fillers such as polytetrafluoroethylene.
In one embodiment, two sides of the second copper bar 2 are respectively propped against the inner sides of two sides of the first copper bar 1, so that the nonmetallic filler can be better wrapped.
In the description of the present specification, a description referring to terms "one embodiment," "some embodiments," "examples," "specific examples," or "some examples," etc., means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present utility model. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
The embodiments of the present utility model have been described above. However, the present utility model is not limited to the above embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
