Principios y precauciones para seleccionar equipos de hornos de templado de vidrio.

Glass tempering furnace is a key equipment in the glass production line, which directly affects the operating efficiency of the entire production line and the quality of glass products. Reasonable selection of glass tempering furnace can not only improve production efficiency and extend the service life of equipment, but also effectively save energy consumption and reduce operating costs.

Principles of glass tempering furnace equipment selection

1. Capacity matching principle

The design capacity of the glass tempering furnace must match the actual capacity of other links in the production line. If the capacity of the tempering furnace is too large, it will cause waste of energy and labor; if the capacity is too small, it will restrict the efficiency of the entire production line. Por lo tanto, when selecting, it is necessary to combine the actual situation of the production line to select a better tempering furnace specification.

2. Process compatibility principle

The tempering process requirements of different glass varieties are different, so the design of the tempering furnace must be compatible with the process of the required tempered glass variety. Por ejemplo, although the tempering processes of flat glass, vidrio automotriz, laminated glass, etc. have something in common, the parameter settings in the heating, cooling, and transportation links are different. Por lo tanto, it is necessary to select a suitable tempering furnace model based on the company’s existing and future product planning.

3. Energy-saving and environmental protection principles

With the increasing attention paid to energy conservation and environmental protection, the glass industry is also facing higher environmental protection requirements. Tempering furnaces are high-energy-consuming equipment, and equipment with high energy efficiency ratio and low pollution emissions should be given priority, which can not only reduce operating costs but also meet environmental protection requirements. In addition to the energy-saving performance of the equipment itself, the design of energy-saving links such as waste heat recovery should also be considered.

Precautions for selecting glass tempering furnace equipment

1. Clarify the size requirements of the tempering furnace

Glass tempering furnaces of different specifications have large differences in size. Por ejemplo, the length of the car window glass tempering furnace is usually 6-9 metros; the flat glass tempering furnace can even reach more than 30 metros. Por lo tanto, before selecting the model, it is necessary to accurately understand the requirements of the production line for the glass size to avoid the inability to produce normally due to inconsistent sizes.

Manufacturing process of slewing bearing and detailed steps

Cojinetes de giro are also called turntable bearings. The main structure includes: inner ring, outer ring, rolling element and rolling element guided cage. It is an important transmission component in mechanical equipment. It is widely used in engineering machinery, light industrial machinery, metallurgical machinery, medical machinery, ship equipment and other industries. Hoy, the slewing bearing manufacturer will take you to understand the manufacturing process and detailed steps of the slewing bearing.

Slewing bearing manufacturing process

Slewing bearing

1. Cutting of slewing bearing steel raw materials

The commonly used raw materials for slewing bearings are integrally hardened carbon chromium bearing steel, and the slewing bearing rings are made of surface hardened steel, generally made of 50Mn steel. The cylindrical raw material billets transported back from the steel plant are cut according to the size required for processing the bearings. En general, carbide saw blades should be used for cutting bearing steel, which has a series of excellent properties such as high hardness, resistencia al desgaste, good strength and toughness, resistencia al calor, y resistencia a la corrosión.

2. Forging of slewing bearing billets

In the heating furnace, the billets are heated and forged into a round cake shape. The forging link is an important link to ensure the reliability and life of the bearing. Después de forjar, the raw materials form the bearing ring blank. Al mismo tiempo, the organizational structure of the raw materials becomes more dense and streamlined, which can improve the reliability and service life of the bearing. Además, the quality of the forging process will directly affect the utilization rate of the raw materials, thereby affecting the production cost.

3. Forging ring of slewing bearing

The steel blank is forged into a ring-shaped steel ring by using a ring rolling machine. Forging can improve the internal organization of steel and improve the strength, plasticity, impact toughness and other mechanical properties of steel.

4. Rough turning

The steel ring after ringing is loaded into the machine tool for rough turning of machining, and various grooves and raceways are turned out. The steel ring is fixed on the gear milling machine and the teeth are cut out. The main purpose is to make the ring after the ring is the same as the shape of the final product, creating conditions for the later grinding machine processing.

5. Temple (heat treatment) of slewing bearing

After machining, the strength and hardness of the steel are improved through quenching operation, and the wear resistance, fatigue strength and toughness of the metal are improved. The heat treatment process is to treat the bearing rings after forging and turning at high temperature. It directly affects the uniformity of carburization in the bearing rings, can improve the wear resistance and hardness of the bearings, and is also an important link that affects the reliability and life of the bearings.

Cómo seleccionar rodamientos de bolas con cuatro puntos de contacto

Rodamientos de bolas con cuatro puntos de contacto are radial single row angular contact ball bearings designed to support axial loads in both directions. They can support a certain degree of radial loads and take up significantly less axial space than double row bearings. The inner ring is a split inner ring, which allows a higher number of balls to be loaded and increases the load carrying capacity. Selecting a four-point contact ball bearing involves considering several key factors to ensure it suits the specific application.

Four-point contact ball bearing selection

four-point contact ball bearings

1. Load Type and Magnitude

Axial Load: Four-point contact ball bearings can handle both radial and axial loads. Ensure that the bearing’s axial load capacity meets the application’s requirements.

Radial Load: Determine the radial load the bearing will be subjected to. Four-point contact ball bearings typically have a lower radial load capacity compared to other ball bearings, so this needs to be considered.

Combined Loads: Four-point contact bearings are particularly useful in applications where both radial and axial loads are present. Make sure to calculate and consider the resulting combined load.

2. Bearing Size and Internal Geometry

Bearing Diameter: The size of the bearing should match the shaft diameter or housing in which it will be installed.

Angulo de contacto: Four-point contact bearings have a contact angle of about 35° that allows them to support both axial and radial loads. Check if this angle aligns with your application’s needs.

Clearance or Preload: This defines the amount of internal clearance between the rolling elements and raceways, which influences the bearing’s performance under load.

3. Speed Requirements

Rotational Speed: Four-point contact bearings are generally suitable for moderate to high-speed operations, but you should verify the maximum speed the bearing can handle by checking the manufacturer’s catalog.

Lubricación: High-speed applications may require special lubrication (oil or grease). Make sure to select a bearing that is compatible with the lubrication type you plan to use.

4. Condiciones ambientales

Temperatura: Consider the operating temperature range. Some four-point contact ball bearings are available with seals or shields for dust, humedad, and temperature resistance.

Corrosion Resistance: If the bearing will be exposed to corrosive environments (p.ej., chemicals or water), choose a bearing with appropriate material coatings, such as stainless steel or ceramic bearings.

four-point contact ball bearings

5. Precision Requirements

Precision Class: Bearings come in different accuracy classes (p.ej., P0, P6, P5). For high-precision machinery, select a bearing with a higher accuracy grade.

Radial Runout and Axial Runout: For high-precision applications, the bearing’s radial and axial runout tolerances should be evaluated.
