Abstract

The utility model discloses a metallic gasket. One or more than one through hole capable of storing lubricating oil is arranged along the circumferential direction of the metallic gasket; the lubricating oil can be stored through the through holes, so that the surface of the metallic gasket, which is contacted with a product, can be fully lubricated, the abrasion is reduced, and the gasket can be designed to be thinner in thickness. Meanwhile, cold extrusion can be performed by adopting a low-carbon steel material, so that the surface of the metallic gasket is peened, thereby, the performance of the gasket is capable of meeting the operating requirement on products with small-torque structures without performing heat treatment or electroplating, the production process steps are reduced, and the cost of the raw material and the production cost are reduced.

Description

Metallic shim

Technical field

The utility model relates to the pad in a kind of fastening piece, relates in particular to a kind of metallic shim.

Background technique

Metallic shim normally forms by high carbon steel, stainless steel or the brass material of high precision, high hardness are refining, is widely used in electronic instrument, mould manufacturing, precision optical machinery, hardware, mechanical parts, stamping part and the hardware manufacturing.In the existing technology; No matter be torsion greatly or the little metallic shim of torsion use when on rubbing surface, assemble be high carbon steel through the heat treatment correct grinding process, nickel plating processes; As depicted in figs. 1 and 2, in order to make metallic shim and the sufficient lubrication of product surface of contact, also need be lubricated the metallic shim lubricant oil of annotating; To reach the requirement in working life, this makes the cost of production of metallic shim high to a certain extent.

The model utility content

The utility model technical problem to be solved provides a kind of metallic shim of the low-carbon steel material at little torsion, and its performance can satisfy usage requirement, and cost is low.

For solving the problems of the technologies described above, the utility model provides a kind of metallic shim, is ring, it is characterized in that, along said metallic shim one or more through holes is set circumferentially.

Said through hole is 6.

Said metallic shim is a low-carbon steel material.

Said metallic shim is by low-carbon steel material cold hobbing and flow harden moulding.

Said metallic shim outer surface comprises an electrodeposited coating.

Said electrodeposited coating material is a zinc.

The thickness of said metallic shim is 1.5mm.

The beneficial effect that the utility model reached:

The metallic shim of the utility model can be stored the oil storage hole of lubricant oil through on pad, being provided with, and the surface of contact of itself and product can be lubricated fully, has reduced wearing and tearing, and the thickness of pad is also programmable thinner; Simultaneously can adopt low-carbon steel material to carry out cold hobbing; Make its surperficial flow harden; Its performance just can satisfy usage requirement under the situation that pad need not heat-treat and electroplate thereby make, and has reduced production craft step, has reduced raw-material cost and cost of production.

Description of drawings

Fig. 1 is a metallic shim schematic representation in the existing technology;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is the metallic shim schematic representation of the utility model;

Fig. 4 is the A-A sectional view of Fig. 3.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described.Following examples only are used for more clearly explaining the technological scheme of the utility model, and can not limit the protection domain of the utility model with this.

Like Fig. 3 and shown in Figure 4, metallic shim 1 upper edge of the utility model circumferentially evenly is provided with a plurality of through holes 2 that can be used for storing lubricant oil, and preferable mode is that 6 through holes are set.Metallic shim 1 adopts low-carbon steel material to carry out cold hobbing, makes its surperficial flow harden.Preferable mode is its plating zinc on surface again after metallic shim 1 moulding, forms a zinc coat.

The thickness of metallic shim 1 can be by the common 1.7mm boil down to 1.5mm that adopts of existing technology medium and high carbon steel pad.

1 high carbon steel pad average production cost of the prior art is: 12 yuan of high carbon steel raw materials, heat treatment process take 5 yuan, and nickel plating technology takes 5 yuan, amount to 22 yuan.

And 1 low carbon steel pad average production cost of the same size of the utility model is: 8 yuan of low carbon steel raw materials, because of 2 yuan of the die costs adjusted of processing through hole, zincincation take 1.5 yuan, 11.5 yuan altogether, has practiced thrift 40% cost of production than existing technology.

The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and distortion, these improvement and distortion also should be regarded as the protection domain of the utility model.
