Description

Technical Field

[0001] The invention relates to the technical field of casting equipment, and in particular to an inclined casting and inclined shrinkage compensation system for a jaw plate casting of a jaw crusher and a use method thereof. Background Art

[0002] Jaw crusher has the characteristics of large crushing ratio, uniform product particle size, simple structure, reliable operation, easy maintenance and economical operating cost. Therefore, it is widely used in mining, building materials, chemical industry, metallurgy and other industries.

[0003] Jaw crusher is a commonly used crushing equipment in mining, building materials and other industries. It mainly crushes materials through the relative movement between the movable jaw and the fixed jaw. The wear resistance and strength of the jaw plate, as a key component of the jaw crusher, directly affect the service life and production efficiency of the crusher. Therefore, how to improve the quality and service life of the jaw plate has long been the focus of the crusher industry.

[0004] Traditional jaw plate production processes mostly use horizontal casting, but due to the complex shape, large surface area and uneven thickness of the jaw plate, horizontal casting can easily lead to defects such as wrinkles on the casting surface and uneven internal shrinkage, which affects the quality of the jaw plate. In addition, since the jaw plate is susceptible to impact and wear during the crushing process, it needs to have high strength and wear resistance.

[0005] However, the traditional casting process of jaw plate castings of jaw crusher has certain limitations, which not only affect the efficiency of the production process, but also directly affect the quality and performance of the final castings.

[0006] In traditional casting methods, the molten steel (iron) is often laid over a large area, which leads to a relatively dispersed energy distribution and increases the difficulty of controlling the casting process. Secondly, the temperature difference control of the molten steel (iron) during the casting process is a delicate job, and the temperature difference between the riser temperature and the casting body is relatively small under traditional methods, making it difficult to achieve the optimal riser shrinkage feeding thermodynamic conditions, which in turn affects the shrinkage feeding effect of the casting, thereby affecting the organizational structure and performance of the casting.

[0007] Shrinkage compensation is a key step in the casting process, but in traditional casting methods, shrinkage compensation is difficult and the effect is often unsatisfactory, which is mainly due to the uneven pressure distribution inside the casting and the limited fluidity of the molten metal. In addition, the shortcomings in the casting design also aggravate this problem, especially the excessive exhaust area and drastic pressure fluctuations, which lead to poor exhaust and easily cause defects such as pores.

[0008] The long-term exposure of the upper cavity of the casting mold to high-temperature baking not only aggravates the thermal stress of the casting mold, but also easily causes a series of casting defects such as box collapse, sand falling, sand inclusion and wrinkling, which seriously damage the appearance and internal quality of the casting.

[0009] The flow stability of molten steel (iron) during the casting process is also a major problem in traditional casting technology. Due to the unstable flow, the temperature of the front end of the molten steel (iron) drops rapidly, which easily forms a cold shut. This defect poses a potential threat to the strength and toughness of the casting.

[0010] To complicate matters further, the choice of casting temperature has become a dilemma. When low-temperature casting is used to improve shrinkage compensation, it often leads to cold shut, surface wrinkling and insufficient casting. On the contrary, increasing the casting temperature to pursue better surface quality may cause negative effects such as insufficient shrinkage compensation, linear (surface) shrinkage or shrinkage holes, and large grain size of the casting, thereby reducing the overall quality of the casting.

[0011] In summary, the traditional casting process of jaw plate castings of jaw crusher has many problems that need to be solved in the technical background. These problems not only limit the improvement of production efficiency and product quality, but also pose a challenge to the development of the entire foundry industry.

The technical principles and technical advantages are as follows:

[0045] (I) Technical Principle

[0046] 1. Scientificity of casting platform design

[0047] (1) Dimension and load-bearing optimization: The dimension design of the casting platform (the length of the casting platform in the X-axis direction is represented by L, and the length in the Y-axis direction is represented by W, L is determined by 1.2-1.5 times the length of the casting sand box, and W is determined by 1.2-1.5 times the width of the casting sand box) fully considers the total weight of the sand box, mold and casting. By introducing a safety factor of 2, it ensures that the platform can still bear stable loads under extreme conditions, effectively preventing deformation or damage caused by overload.

[0048] (2) Support and fulcrum layout: The double-sided support and fulcrum design not only enhances the stability of the platform, but also optimizes the mechanical structure through reasonable spacing (0.8W) distribution, reduces stress concentration, and improves the durability of the overall structure.

[0049] (3) Tilt adjustment mechanism: The tilt lifting system is used to achieve precise adjustment of the casting platform angle, with a maximum tilt angle of (+)(-)15 degrees. This design allows the casting to flow naturally during the casting process, reducing bubbles and inclusions and improving the internal quality of the casting.

[0050] 2. Stable and reliable mechanism design and convenient operation

[0051] At the equipment level, the tilted casting and tilted shrinkage compensation system of the jaw crusher jaw plate casting of the present invention introduces a tilted lifting system. This design not only improves the stability and reliability of the casting process, but also greatly simplifies the operation process. The training cost of operators is reduced, production efficiency is improved, and casting defects caused by human operating errors are reduced, further enhancing the overall performance and competitiveness of the system.

[0052] (II) Technical advantages

[0053] 1. Improve casting quality

[0054] (1) Natural shrinkage and exhaust: Inclined casting and inclined shrinkage system allow molten steel or iron to flow naturally into the mold cavity under the action of gravity, effectively promoting shrinkage inside the casting and reducing defects such as shrinkage cavities and shrinkage. At the same time, the adjustment of the tilt angle helps to smoothly discharge gas and inclusions, improving the density and cleanliness of the casting.

[0055] (2) Uniform cooling: The adjustment of the inclination angle can also promote the balanced cooling rate of various parts of the casting, reduce the internal stress concentration and deformation caused by uneven cooling, and further improve the dimensional accuracy and mechanical properties of the casting.

[0056] 2. Improve production efficiency

[0057] (1) High degree of automation: The tilt angle can be easily adjusted and the platform can be reset horizontally through the control panel, which reduces manual intervention and improves the automation level of the production process.

[0058] (2) Shorten the production cycle: The inclined casting and inclined shrinkage feeding system optimize the casting process, allowing the casting to reach a solidified state faster, thereby shortening the production cycle and improving production efficiency.

[0059] 3. Enhanced safety and durability

[0060] (1) Safety design: The casting platform and tilt lifting system have undergone strict safety factor calculation and structural design to ensure safety during operation.

[0061] (2) Good durability: The use of high-strength steel structural plates and I-beam frames ensures the long-term stability and durability of the casting platform and reduces maintenance costs.

[0062] In summary, the method for using the inclined casting and inclined shrinkage compensation system of the jaw crusher jaw plate casting of the present invention, by virtue of its scientific design principle and significant technical advantages, brings a more efficient and higher-quality solution to the casting industry.

[0063] The present invention has the following beneficial effects:

[0064] 1. The inclined casting and inclined shrinkage compensation system of the jaw plate casting of the jaw crusher of the present invention adopts horizontal casting or negative angle casting, and the casting method of inclined shrinkage compensation. After the casting, the whole casting mold is inclined at a certain angle, and the shrinkage compensation riser is at the highest position. The casting temperature can be appropriately reduced, and the high temperature and high pressure shrinkage compensation effect can be achieved at a lower casting temperature, which effectively reduces the negative impact of high temperature casting liquid on the cooling of the jaw plate of the jaw crusher; when negative angle casting is selected, the impact of molten steel on the mold cavity can also be effectively reduced, avoiding casting defects such as slag inclusion and pores caused by turbulent flow of molten steel.

[0065] 2. The inclined casting and inclined feeding system of the jaw plate casting of the jaw crusher of the present invention reduces the number of feeding risers. It is only necessary to place the feeding riser on one side of the sprue, thereby increasing the temperature and effective height of the molten steel at the feeding riser, and facilitating the generation of temperature gradient and pressure gradient.

[0066] 3. The inclined casting and inclined shrinkage compensation system of the jaw plate casting of the jaw crusher of the present invention adopts an inclined lifting system, which is stable and reliable, easy to operate, and saves labor costs.

[0067] 4. The inclined casting and inclined shrinkage compensation system of the jaw plate casting of the jaw crusher of the present invention solves to a certain extent the problems existing in the traditional casting of the jaw plate casting of the jaw crusher, such as the difficulty in selecting the casting temperature, the poor shrinkage compensation effect of the casting riser, and the surface quality of the casting failing to meet the requirements, which in turn lead to the problems of low casting production efficiency and difficulty in meeting the design requirements for product quality, thereby saving equipment maintenance and labor costs and increasing product profit margins.

[0098] The tilting and lifting system includes an oil pump motor unit 10, a piston cylinder 11, and a support column 15. The motor power of the oil pump motor unit 10 is designed according to the total weight carried by the casting platform 13, and the stroke length of the piston cylinder 11 is designed according to the maximum and minimum tilt angles.

[0099] The support columns 15 are located below the casting platform 13.

[0111] When further exploring the optimization path of the casting process, the introduction of the inclined casting and inclined shrinkage feeding system of the jaw crusher jaw plate casting of the present invention marks a significant technological innovation. Compared with the traditional casting device of the jaw crusher jaw plate casting, it shows significant technical advantages in many key aspects, as follows:

[0112] 1. Innovation of casting and shrinkage compensation mechanism

[0113] Traditional casting devices for jaw plate castings of jaw crushers often face the problems of large horizontal steel paving area, great difficulty in temperature difference control and poor shrinkage compensation effect. The inclined casting and inclined shrinkage compensation system for jaw plate castings of the jaw crusher of the present invention innovatively adopts the technical solutions of horizontal casting and inclined shrinkage compensation. This strategy not only optimizes the flow path of molten steel and reduces the uneven temperature caused by the large flat paving area, but also effectively utilizes the natural shrinkage compensation mechanism under the action of gravity through inclined shrinkage compensation, significantly improving the shrinkage compensation efficiency and quality. In addition, the mold design after inclined casting enables the riser to be in the highest position, thereby achieving efficient shrinkage compensation under high temperature and high pressure, further making up for the shortcomings of traditional shrinkage compensation methods.

[0114] 2. Optimization control of casting temperature

[0115] In view of the problem that the casting temperature is difficult to accurately control in the traditional casting device of the jaw plate casting of the jaw crusher, the inclined casting and inclined shrinkage compensation system of the jaw plate casting of the jaw crusher of the present invention has proposed a strategy for appropriately reducing the casting temperature through theoretical analysis and practical verification. This adjustment effectively reduces the heat loss of molten steel during the casting process while maintaining the basic performance of the casting, slows down the rapid drop in the temperature of the front end of the molten steel, and thus reduces the occurrence of casting defects such as cold shuts. At the same time, when it is necessary to improve the surface quality, the inclined casting and inclined shrinkage compensation system of the jaw plate casting of the jaw crusher of the present invention also provides flexible adjustment space. By appropriately increasing the casting temperature and combining with an optimized shrinkage compensation mechanism, problems such as insufficient shrinkage compensation, shrinkage porosity, and shrinkage holes are effectively avoided, thereby ensuring the overall quality and performance of the casting.

[0116] 3. Synergistic effect of riser design and casting optimization

[0117] The inclined casting and inclined shrinkage compensation system of the jaw plate casting of the jaw crusher of the present invention realizes the deep coordinated optimization of the riser and the casting mold in design. By reducing the number of risers and concentrating them on one side of the sprue, it not only simplifies the casting process, but also improves the temperature concentration of the riser molten steel, which is conducive to forming a more ideal temperature gradient and promoting uniform cooling and solidification of the casting. In addition, the inclined design of the casting mold after casting further strengthens the shrinkage compensation function of the riser, ensuring the steady improvement of the internal quality of the casting.

[0118] 4. Stable and reliable mechanism design and convenient operation

[0119] At the equipment level, the tilted casting and tilted shrinkage compensation system of the jaw crusher jaw plate casting of the present invention introduces a tilted lifting system. This design not only improves the stability and reliability of the casting process, but also greatly simplifies the operation process. The training cost of operators is reduced, production efficiency is improved, and casting defects caused by human operating errors are reduced, further enhancing the overall performance and competitiveness of the system.

[0120] In summary, the tilted casting and tilted shrinkage feeding system of the jaw plate casting of the jaw crusher of the present invention has shown significant technical advantages in casting and shrinkage feeding mechanism, casting temperature control, riser design and mold optimization, and stability, reliability and convenience of mechanism design. These improvements not only effectively solve many problems existing in the traditional casting device of the jaw plate casting of the jaw crusher, but also promote the overall progress and development of the casting process.
