Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, fig. 2 and fig. 3, fig. 1 and fig. 2 are schematic structural diagrams of a first viewing angle and a second viewing angle of the preform 100 provided in this embodiment, respectively, and fig. 3 is a schematic perspective structural diagram of the preform 100 provided in this embodiment.
The embodiment provides a preform 100, which includes a ceramic substrate 110 and a steel block 120 embedded in the ceramic substrate 110, where the ceramic substrate 110 is provided with a via 130, one end of the via 130 extends to a surface of the ceramic substrate 110, and the other end is close to the steel block 120.
In this embodiment, the ceramic substrate 110 has a first surface 111, a second surface 112 opposite to the first surface 111, and a side surface 113 surrounding the first surface 111, and the ceramic substrate 110 has a plurality of first channels 131 and a plurality of second channels 132. The first and second ports 131 and 132 in the embodiment of the present application are used for filling molten steel so that metal is combined with ceramic. One end of the first channel 131 extends to the first surface 111 of the ceramic substrate 110, and the other end is close to the steel block 120; one end of the second porthole 132 extends to the side 113 of the ceramic base 110 and is close to the edge of the first surface 111 of the ceramic base 110, and the other end is close to the steel block 120.
The structure is that the first duct 131 and the second duct 132 extend from the surface of the ceramic substrate 110 to the steel block 120, so that the steel block 120 is used as a chilling block to accelerate the solidification of the molten steel around the steel block 120 in the process of compositing the ceramic substrate 110 with the molten steel, and the molten steel around the preform 100 is prevented from solidifying first and then, so that the molten steel in the ceramic substrate 110 is prevented from cooling and shrinking to form a shrinkage cavity to influence the toughness of the solidified steel.
In the present embodiment, the first cell channels 131 and the second cell channels 132 are rectangular bodies, the lengths of the first cell channels 131 and the second cell channels 132 are set according to the size of the ceramic substrate 110, and the length of the first cell channels 131 is greater than the length of the second cell channels 132. In other embodiments of the present application, the shapes of the first and second hole channels 131 and 132 may also be cylinders or other prisms, which are not limited in the present application.
In some embodiments of the present disclosure, the axial direction of the first channel 131 forms a first angle with the side surface 113 of the ceramic substrate 110, and the degree of the first angle is 0 to 45 degrees. The structure enables the length direction of the first pore channels 131 to be approximately parallel to the direction of the impact on the first surface 111 of the ceramic matrix 110, and the direction of the impact between the material and the wear surface is not more than 45 degrees according to the wear mechanism, which is beneficial to reducing the wear loss. After forming the wear-resistant part, the ceramic substrate 110 is firstly contacted with the ceramic-metal composite material during impact, which is equivalent to instantaneous impact Ft ═ Δ P, the composite material has good compression resistance effect, so that the material is cracked due to the impact generated by self energy conversion, and a good impression protection effect is achieved on the metal substrate of the wear-resistant part. If the impact direction is perpendicular to the abrasion direction, i.e. the length direction of the first channel 131 is perpendicular to the impact direction, the ceramic metal composite material is cut layer by layer or broken off easily due to the resistance to compression and resistance to tension, so that the abrasion is fast.
In the present embodiment, the axial direction of the first via 131 is parallel to the side surface 113 of the ceramic substrate 110, i.e., the extending direction of the first via 131 is perpendicular to the first surface 111 of the ceramic substrate 110. This structure helps the wearing resistance of the wearing part action face to a great extent.
In some embodiments of the present application, the first channel 131 near the steel block 120 extends from the first surface 111 of the ceramic substrate 110 to the steel block 120, i.e., the first channel 131 communicates with the ceramic substrate 110, so that the molten steel contacts the steel block 120 after being poured into the ceramic substrate 110, thereby increasing the cooling solidification rate of the molten steel. In order to make the impact resistance and wear resistance of the wear resistant member after the metal is combined with the ceramic substrate 110 uniform, the plurality of first portholes 131 in the embodiment of the present application are arranged in a matrix. In other embodiments of the present application, the plurality of first conduits 131 are randomly arranged or arranged in other manners, which is not limited in the present application.
The wear part formed by the ceramic base 110 is not only impacted on one surface during application, but often also on the side 113. In order to increase the wear resistance of the side 113 of the wear part and to reduce the wear of the wear part, the ceramic base body 110 is provided with a plurality of second portholes 132. One end of the second porthole 132 extends to the side 113 of the ceramic base 110 and is close to the edge of the first surface 111 of the ceramic base 110, and the other end is close to the steel block 120.
In some embodiments of the present disclosure, the axial direction of the second channel 132 has a second angle with the first surface 111 of the ceramic substrate 110, and the second angle is between 0 and 45 degrees. The structure enables the length direction of the second pore channels 132 to be approximately parallel to the direction of the impact on the side surface 113 of the ceramic matrix 110, and the material and the abrasion surface impact in a 45-degree direction according to an abrasion mechanism, which is beneficial to reducing the abrasion loss. In the present embodiment, the axial direction of the second via 132 is parallel to the first surface 111 of the ceramic substrate 110, i.e., the extending direction of the first via 131 is perpendicular to the side surface 113 of the ceramic substrate 110. This configuration contributes to an improved wear resistance of the corners of the wear part sides 113.
In the embodiment of the present application, the ceramic substrate 110 has a first side surface 1131 and a second side surface 1132 opposite to the first side surface 1131, an edge of the first side surface 1131 close to the first surface 111 has two corner regions, an edge of the second side surface 1132 close to the first surface 111 also has two corner regions, and one end of each of the second pore channels 132 is disposed in each of the four corner regions. In the embodiment of the application, each corner area is provided with nine holes arranged in a matrix, and the structure is helpful for improving the abrasion resistance of the corners of the side surfaces 113 of the abrasion-resistant parts, so that the abrasion resistance of the abrasion-resistant parts can be ensured to a greater extent. In other embodiments of the present application, a plurality of second ducts 132 may be formed on the edges, not only corner regions, of the first side surface 1131 and the second side surface 1132 close to the first surface 111, and the arrangement manner may be set according to requirements, which is not limited in the present application.
Since the first surface 111 of the ceramic substrate 110 is mainly provided with the holes of the first via 131, the length of the second via 132 is not too long so as to avoid affecting the arrangement of the first via 131. Preferably, the length of the second pore channels 132 is one fifth to one tenth of the length of the ceramic matrix 110 in the length direction.
The preform 100 is subsequently combined with molten steel to form a wear part, which generally needs to be connected to a mechanical arm or the like for crushing. However, molten steel (iron) such as molten iron of high-chromium cast iron has high hardness after solidification, and is difficult to machine, and if machining is performed on high-chromium cast iron, the hammer head may be cracked. The present application realizes the connection of wearing parts through the preset steel piece 120. To improve the machinability of the wear part, the steel block 120 is a low carbon steel, such as a Q235 block, 45 steel, or other tool carbon steel, which has low strength and low hardness and can be machined after casting. In this embodiment, set up the screw hole that is used for connecting on steel block 120 to with bolted connection, make things convenient for the dismantlement in the in-service use process.
In the embodiment of the present application, the steel block 120 is disposed at the center of the preform 100, so that the formed wear-resistant member, such as a hammer, can effectively provide a force conduction path in the use process, and the force applied to each position of the wear-resistant member is uniform.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a preset steel block 120 provided in an embodiment of the present application. In the embodiment of the present application, the steel block 120 includes a first steel block 121 and a second steel block 122 fixedly connected, the first steel block 121 is disposed near the second surface 112 of the ceramic substrate 110, and the second steel block 122 is disposed on a side of the first steel block 121 away from the second surface 112 of the ceramic substrate 110. The first and second steel blocks 121, 122 differ in size in a direction parallel to the second surface 112 of the ceramic substrate 110. This structure makes the bonding between the steel block 120 and the ceramic base 110 more stable. In this embodiment, the dimension of the first steel block 121 in a direction parallel to the second surface 112 of the ceramic substrate 110 is smaller than the dimension of the second steel block 122 in that direction. The structure has the effect of mechanical riveting and locking, and can improve the stability of the pre-embedded block and the ceramic matrix 110, so that the abrasion-resistant part formed by the prefabricated part 100 cannot break away from the splitting accident in the process of high-speed rotation. In the embodiment of the present application, the first steel block 121 and the second steel block 122 are both rectangular parallelepipeds. In other embodiments of the present application, the first steel block 121 may be a cylinder, and the second steel block 122 is a rectangular parallelepiped, and the present application does not limit the specific shape thereof.
The present application further provides a wear part (not shown) comprising a preform 100 and a steel material wrapping the surface of the preform 100 and filling the first and second portholes 131, 132. The bottom and the corner area of the side edge of the wear-resistant part of the structure are made of composite materials of steel and ceramics.
The wear-resistant part has the following beneficial effects:
1. good toughness and difficult cracking in service process
The wear part has an outer wear surface of a steel-ceramic composite and an inner pre-positioned steel block 120. In the process of fusing the molten steel with the steel block 120, the molten steel grains are refined due to the chilling action of the preset steel block 120, the toughness of the steel is improved, and the probability of integral fracture of the wear-resistant part in the service process is reduced.
2. Simple machining, low cost and convenient disassembly
Due to the fact that the preset steel block 120 is low in hardness, the steel block 120 can be machined, machining limitation is avoided, and machining is simple. The steel block 120 can be connected with a bolt, the bolt is independent of parts, and the on-site installation and the disassembly are simple and convenient. The steel block 120 is low in purchase cost and reduces cost.
3. Low density and weight
The proportion of the hammerhead is ceramic material, so the density of the ceramic material is only 4.5-5.5g/cm3Therefore, compared with the original high manganese steel, the weight of the combined hammer can be reduced by about 10 percent, a better part lightweight effect is achieved, and the power output of a motor and the bearing loss can be reduced.
