Supply tin bronze bushing parts

Supply tin bronze bushing parts
Hot-die forging presses are used in manufacturing industries such as automobiles, tractors, internal combustion engines, ships, aviation, mining machinery, petroleum machinery, hardware tools, etc. to carry out die forging and finishing forgings of ferrous and non-ferrous metals in large quantities in batches, and are indispensable high precision forging equipment for modern forging production.

The hot die forging press is mainly composed of body, motor support, drive shaft, crankshaft, combine, brake, slider, upper top material, lower top material, balancer, flywheel brake, pneumatic system, water cooling device, lubrication system, foot switch, cam switch, electrical system, etc.

When the hot die forging press is working, the torque of the motor is transmitted from the small pulley to the large pulley on the drive shaft through the v-belt, and then the torque is transmitted to the large gear on the crankshaft through the small gear at one end of the drive shaft, and the floating block friction clutch is fixed to the large pulley on the large gear, and the floating block brake is at the other end of the crankshaft, and the middle of the crankshaft is equipped with a connecting rod, and the connecting rod and the slider are connected together through the tension brake, tight lever and pressure pin. When the press is working, the clutch and the brake are fed at the same time. Since the volume of the brake cylinder is smaller than that of the clutch cylinder, the clutch is combined only after the brake is disengaged, driving the crankshaft to rotate and driving the slider through the connecting rod to move vertically in the body guide. Workbench The press is a two-stage drive, the first stage is belt drive, the second stage is herringbone gear drive, flywheel is set on the drive shaft, and the main actuator is the crank slider mechanism.

In the process of using the hot-die forging press, due to the failure of the automatic oil distributor detection device, resulting in the lack of oil between the crank journal and the sliding bearing to form dry friction, resulting in local wear, and then contact fatigue, the sliding bearing surface is partially stripped, forming progressive friction damage, resulting in losses to production, so the quality of the copper bushing is relatively high. Our company produces hot-die forging press bronze bushing material is generally tin bronze zCuSn10Pb1.

Bearing bushings copper bush is an important part of the sliding bearing, the main form of failure is wear, fatigue wear due to insufficient strength and bushing off due to process reasons. For the selection of bearing bushing material, the following aspects are mainly considered: (1) strength, plasticity, compliance and embedded sex; (2) wear, friction and wear resistance; (3) corrosion resistance; (4) lubrication performance and thermal properties (5) process; (6) economy.

Centrifugal Casting of Large Copper Sleeves

Centrifugal Casting of Large Bronze Bushing

The production of copper sleeves by centrifugal casting has a wide range of applications. By coating the surface of the mold with sand and controlling key processes such as alloy smelting, filling and pouring, the defects such as pores and slag inclusions on the surface of the copper sleeve are solved, and high-quality products are produced. copper sleeves for large ships.

Custom Bearings are available

Bearings are available in 3 standard bronze alloys:

Standard material fulfills most application requirements
High load capacity with maximum corrosion resistance
Highest load capacity, but less corrosion resistance

Industrial: Offshore industry, underwater equipment, bridges and civil engineering, iron and steel industry equipment, cranes and conveyors, deep and open cast mining equipment, construction and earthmoving equipment, etc.

Water lubricated solid lubricant inserts bearing is a new product with solid lubricant inlaid on high – force brass or tin bronze.It breaks through the limit that the general bearing depends on oil film lubrication.Suitable for high temperature, high load, corrosion resistance or no refueling and other occasions.Its hardness is twice as high as the general copper set, wear resistance is also twice as high.At present, it is widely used in metallurgical continuous casting machine, steel rolling equipment, mining machinery, ships, gas turbine, injection molding machine, light industry machinery, machine tool industry and equipment production line.

Water lubricated solid lubricant inserts cast bronze bearings advantages:

It can work completely under the condition of no oil feeding;
Self-lubricating, and the lubrication performance is better than RCB650
Good lubricity and structural integrity in all environmental conditions;
Can work in the most extreme temperature, more than 1200 degrees Celsius, far below the freezing environment;
The environmental protection

Note: The size can be customized

Self-Lubricating, Maintenance-Free Cast Bronze Bushings With Solid Lubricant Inserts Bearings Are Designed For Applications With High Specific Loads, Long Dwell Periods Under Static Loading, And Low Sliding Speeds, As Well As Applications That Cannot Be Conventionally Lubricated. In Addition, They Can Be Used To Replace Existing Greased Bearings.

Cast Bronze Bearing

There are many kinds of copper sleeves, including machine copper rollers, copper bearings, etc. Oil lubricated bearings are used in various large and heavy machinery and are an important component of machinery.

Copper sleeves, also known as copper bushings, are divided into many types, including machine copper rollers, copper bearings, etc. It is used in various light industry, large and heavy machinery and is an important component of machinery. The product has the traditional tin bronze bearing function. It is made of electrolytic copper as raw material with various trace metal elements, sintered at high temperature, and processed by air pressure centrifugal casting. High hardness, excellent wear resistance, not easy to cause seizure, good casting performance and cutting performance, and good corrosion resistance in the atmosphere and fresh water. In the absence of lubricants and water-based lubricants, it has good sliding properties and self-lubricating properties, easy cutting, poor casting properties, and good corrosion resistance to dilute sulfuric acid. Structural parts for general purposes, simple-shaped castings used in ships, instruments, etc., such as sleeves, bushings, bearing bushes, sliders, etc.

Bronze Bearing Material

The material of the copper sleeve is as follows:
