Detailed Description
As used in the specification and in the claims, certain terms are used to refer to particular components. As one skilled in the art will appreciate, manufacturers may refer to a component by different names. This specification and claims do not intend to distinguish between components that differ in name but not function. The description which follows is a preferred embodiment of the present application, but is made for the purpose of illustrating the general principles of the application and not for the purpose of limiting the scope of the application. The protection scope of the present application shall be subject to the definitions of the appended claims.
The present application will be described in further detail below with reference to the accompanying drawings, but the present application is not limited thereto.
The first embodiment is as follows:
as figure 1 the utility model provides a structural schematic diagram of wear-resisting welt shocks resistance is shown, the utility model provides a pair of wear-resisting welt shocks resistance, a serial communication port, including ceramic block 1, cavity 2 and installation steel sheet 3, wherein, ceramic block 1 evenly distributed in constitute the face of shocking resistance of welt in cavity 2, installation steel sheet 3 set up in ceramic block 1 with the bottom of cavity 2, ceramic block 1, cavity 2 and installation steel sheet 3 compound bonding between two liang have rubber layer 4. The rubber layer 4 is preferably a rubber vulcanizate.
The utility model discloses well pottery chooses zirconium aluminium composite ceramic that shock resistance and toughness are good for use, and ceramic structure chooses for use the taper shape, and it is poor to have certain diameter from top to bottom, is provided with protruding curved surface atress structure above the pottery, and pottery height-diameter ratio is about 1-2. The cast iron is made of high manganese steel or high chromium cast iron according to different impact working conditions and matched with corresponding heat treatment processes. The aperture of the cast iron is larger than the diameter of the ceramic, and rubber vulcanization buffer layers with certain thickness are arranged around the ceramic and the cast iron in contact. The ceramic and cast iron bottom and a steel plate are vulcanized into a whole, so that the installation is convenient.
The working principle of the lining plate is that when a large material falls from a high position, the large material firstly contacts the ceramic block 1 on the upper layer of the lining plate, and the impact force of the material on the surface of the lining plate can be partially decomposed because the ceramic block 1 is of a spherical surface protrusion structure; secondly, the impact force conducted downwards is transmitted to the rubber layer 4 with high elasticity through the cavity 2, namely the cast iron layer, most of the impact force is absorbed, and the residual force is absorbed through the cavity 2 with good toughness, namely the cast iron layer, so that the long-time work of the lining plate is ensured.
The mounting steel plate 3 is a square mounting steel plate. The mounting steel plate 3 is square, the back surface of the mounting steel plate is mounted at an anti-abrasion part of the equipment through bolts, so that the mounting and splicing of most occasions are facilitated, and the application range is wide. According to the mechanism that the lining plate is worn and impact-resistant, a brand-new concept of high-wear-resistance impact-resistant lining plate is formed, and the lining plate has the advantages of wear resistance, impact resistance, no material accumulation, light dead weight, convenience in replacement, high safety coefficient, high comprehensive cost performance and the like.

The preparation process of the cavity 2 comprises the following steps: according to the actual working condition, high manganese steel, high chromium cast iron or other wear-resistant metal materials are selected and manufactured through casting and corresponding heat treatment processes. In the cast iron lining plate, edges between holes are designed to be about 5-10mm, the size of the whole lining plate is controlled within 500mm x 100mm, cracks are not allowed to appear in the casting process of the lining plate, the size tolerance is controlled within +/-1 mm, the surface of the lining plate is smooth, the surface and the holes are processed cleanly through sand blasting, and the luster of a metal body is exposed.
The ceramic block 1, the cavity 2 and the mounting steel plate 3 are subjected to pretreatment processes such as cleaning, sand blasting, glue spraying, glue brushing and the like. The vulcanization is divided into two steps, after rubber is wound on the periphery of the ceramic block 1, the ceramic block is fixedly placed in a hole of the cavity 2 to be vulcanized for one time, a rubber layer 4 with the thickness of 2mm is filled between the ceramic block 1 and the cavity 2, the ceramic block 1 and the cavity 2 are integrated, and meanwhile, the cavity 2 also plays a role in protecting the ceramic block 1, so that the ceramic block 1 is not easy to break. After the first vulcanization, rubber is paved between the cavity 2 and the bottom installation steel plate 3 for second vulcanization. The two times of vulcanization can ensure that the ceramic block 1, the cavity 2 and the mounting steel plate 3 are well combined.
