Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of roll forgings, and in particular relates to a recyclable roll forging. Background Art
[0002] Rollers are the main working parts and tools on the rolling mill that cause continuous plastic deformation of metal. Rollers are divided into cast rolls, forged rolls, surfacing rolls, and sleeve rolls according to their manufacturing methods. Forged rolls are further divided into integral rolls and composite rolls.
[0003] In the existing technology, roll forgings are divided into integral rolls and composite rolls. Composite rolls are mainly made of different materials for the outer layer of the roll body and the core (including the roll neck part), and the two materials are metallurgically bonded. Composite rolls can not only meet the requirements of the rolling mill for the wear resistance, thermal fatigue resistance and other performance of the roll body, but also ensure the toughness of the core and the roll neck. The main outer layer and core of the composite roll are mainly made of metal materials and have a high recycling value. However, during the use of the composite roll, the roll body and the core are prone to wear, and after wear, the roll body and the core are easily damaged, thereby affecting the recycling value of the roll forging. Therefore, we propose a recyclable roll forging. Utility Model Content
[0004] The purpose of the utility model is to provide a recyclable roll forging to solve the technical problem that the roll body and the core of the existing composite roll forging are easily worn during use, thereby causing serious damage to the roll body and the core and affecting the recycling value, so as to achieve the purpose of delaying the wear between the roll body and the core and improving the recycling value.
[0005] In order to solve the above technical problems, the utility model provides a recyclable rolling mill forging, including a roll core, a roll body is provided on the outer periphery of the roll core, and a fixing seat is provided on the inner side of the roll body near both sides and on the outer periphery of the roll core near both sides, an oil storage cavity is provided on the inner side of the fixing seat, and the oil storage cavity is used to store lubricating oil, an oil filter mesh connected to the inner side is provided on the inner side of the fixing seat, and the oil filter mesh is made of alloy material, a limiting ring is fixed to the inner side of the fixing seat and on the outer periphery of the roll core, and the limiting ring is fixed to the roll core.
[0006] Furthermore, both sides of the roller core are integrally formed with shaft necks, and the side of the shaft neck away from the roller core is integrally formed with a shaft head.
[0007] Furthermore, an operating head is fixedly connected to a side surface of the shaft head on the right side, and a connecting head is fixedly connected to an end of the shaft head on the left side.
[0008] Furthermore, an oil filling port is provided on the opposite side of the fixing seat and near the top, and the oil filling port is communicated with the oil storage cavity.
[0009] Through the above solution, by setting the oil filling port, the oil filling port is convenient for injecting lubricating oil into the interior of the oil storage cavity, thereby facilitating the loading of the oil storage cavity.
[0010] Furthermore, the periphery of the oil filling port is threadedly connected to a sealing cover, and a sealing rubber ring is clamped on the inner side of the sealing cover and located on the periphery of the sealing cover.
[0011] Through the above solution, by providing the sealing cover, the sealing cover can effectively seal the oil filling port, and the sealing can effectively prevent the lubricating oil in the oil storage cavity from leaking.
[0012] Furthermore, a stainless steel filter is fixedly connected to the interior of the oil storage cavity and at the opening of the oil filling port. The interior of the stainless steel filter is filled with an impurity filter layer, and the impurity filter layer is made of cotton material.
[0013] Furthermore, a slow-release layer is provided on the inner side of the oil storage cavity and on the outer periphery of the oil filter, and the slow-release layer is made of a slow-release cotton material.
[0014] Through the above solution, by setting the slow-release layer, the slow-release layer can slowly penetrate the lubricating oil through the oil filter to the limit ring, thereby effectively ensuring that the limit ring is lubricated with lubricating oil for a long time, thereby reducing the wear between the roller core and the roller body.
[0015] The beneficial effects of the utility model are:
[0016] 1. Through the setting of the fixed seat, the fixed seat can effectively connect the roller core and the roller body, thereby ensuring the stability of the connection, and the oil storage chamber can effectively store the lubricating oil, and the oil filter can effectively release the lubricating oil. By releasing the lubricating oil, it is ensured that there is lubricating oil on the limit ring for a long time. In this way, it can effectively ensure that the connection between the roller core and the roller body is lubricated by the lubricating oil during operation, which can reduce wear and tear, thereby ensuring that the roller body and roller core will not be damaged due to wear, thereby increasing the recycling value and facilitating the recycling of the roller body and roller core.
[0017] 2. Through the setting of the slow-release layer, the slow-release layer can slowly release the lubricating oil inside the oil storage chamber onto the limit ring. In this way, the lubrication of the limit ring can be guaranteed for a long time, and wear can be effectively reduced. At the same time, there is no need to add lubricating oil for a long time, which can effectively avoid the trouble caused by the frequent need to add lubricating oil. Through the setting of the stainless steel filter mesh and the impurity filter layer, the impurities in the lubricating oil can be effectively filtered. By filtering the impurities in the lubricating oil, the impurities can be effectively prevented from penetrating into the limit ring and affecting the lubrication effect.
