Concrete mixer chassis maintenance four major items
It is very important for concrete mixers to be maintained and maintained. Let's elaborate on this issue with our partners: 1. Regularly check the oil environment of each important assembly of the concrete mixer truck: the mobilization machine, transmission, brake system, power steering system, etc. It is generally possible to check by hand when refueling to see whether the oil of each tank is above or below. Between the two tick marks, if it is lower than the lower tick mark, it must be added in real time. The added engine oil must be the same type of engine oil used in the original model, so as to avoid the difference between the other engine oil (selection standard of the concrete mixer lubricant). Together, they cause chemical reverberation, which in turn makes the engine oil deteriorate and lose its dyeing. If the oil level drops quickly, it indicates that the system has leaks, and it is necessary to quickly check out the leaked parts and repair it in real time. 2, pay attention to the brake pads (two strokes to determine the concrete mixer brake pads need to change) and the clutch plate wear changes in real time: brake pads and clutch plates these two friction plates are depleting products, after a period of time will be loss, loss of the original With results, if it is not changed in real time, it can easily become a car accident. For serenity, it is best to install an electronic signal sensor. The brake indicator on the instrument panel will light up when about 1.5 mm of the friction plate remains. This reminds the driver (Concrete Mixer Truck Co., Ltd., a common knowledge of concrete mixers). Replace the friction plate. If in a rainy, wet weather, the friction plate will receive water, the friction will be significantly lower, the tanker will first lightly step on the brakes and clutches a few times, and the heat generated by the friction will evaporate the water on the friction plate. Then get out of the car. 3, four-wheel alignment is very important: use concrete mixer to bias the disk if the sentiment is different, they should go to the repair shop to do four-wheel positioning checks, and make the appropriate mediation. The appearance of the four wheels seems to be standing upright on the ground. It is not true. If you measure with an instrument, there is usually a deviation of 0.5 to 2 degrees. The naked eye does not look out. Don't look at the small 0.5 to 2 degree deviation. Selecting the steering function of the tanker will greatly reduce the maneuverability. 4, the maintenance of concrete mixer tires: often check the tire pressure, especially in the summer, high air pressure, easy to puncture, small tilt, shake head, then roll over; pressure is too low, increase resistance, corresponding increase in fuel consumption. Change the front and rear tires after the necessary mileage, because the weight of the two is not equal, and the wear is not equal. Before and after the tires change each other, the service life of the concrete mixer tires can be delayed and the cost of the vehicle can be saved.
Sheet Metal Fabrication
Definition of sheet metal fabrication
Sheet Metal fabrication is the creation of useful metallic parts and structures by the application of multiple fabrication processes. Sheet metal fabrication is basically a broad term that involves various complex processes like cutting, forming, bending, welding, machining, and assembling. The instructions include below: materials, processes, and tools required for sheet metal fabrication.
Types of Sheet Metal Fabrication Materials
The choice of metal depends on the final use of the fabricated parts.
Common fabrication processes:
· Carbon Steel
· Stainless Steel
· Aluminum
· Bronze
· Copper
· Brass
· Aluminized steel
· Galvanized steel
Types of Metal Fabrication Processes
The journey to the final product from raw sheet metals proceeds through various sheet metal fabrication processes. All the sheet metal fabrication processes can be grouped into the following three categories:
· Cutting
· Deformation
· Assembly
Sheet metal fabrication: Cutting
ii. Water jet cutting
iii. Plasma cutting
Sheet metal fabrication: Forming or Deformation
Bending: Sheet metal bending is one of the most popular deformation processes. A machine known as a Press brake is used to bend sheet metals into V, U, or other complex shapes. With an increase in gauge thicknesses of sheet metals the force required to bend increases.
Stamping: In the stamping process, a hydraulic or mechanical stamping press equipped with a tool and die is used to perform specific tasks like curling, drawing, embossing, flanging, etc
Hemming: Hemming is a process by which the edges of sheet metal are folded over itself or another piece of sheet metal to create a rounded edge. In the sheet metal fabrication process, two types of hemming processes are widely involved. They are roll hemming and conventional die hemming. Conventional hemming is used for mass production. A hemming roller is used for roll hemming.
Spinning: Spinning is a metal fabrication process where a lathe machine is used to rotate the sheet metal against a tool to produce conical or cylindrical shapes.
Sheet metal fabrication: Assembly
Assembly is basically joining Sheet Metal Components produced using above mentioned cutting or bending processes. The common sheet metal assembly process consists of joining by Welding and joining using fasteners.
Welding: In the welding process, sheet metal components are joined together by melting sections with the application of heat to form a solid connection. There are various processes available that are used to weld sheet metals.
Joining using Fasteners: Similar or dissimilar sheet metal parts can easily be joined using fasteners like bolts, screws, rivets, etc.
Brazing: Brazing is a process similar to welding that operates by melting a filler without melting the sheet metals.
Adhesives: Adhesives can be used to hold metal sheets together in conjunction with other joining methods
Advantages and Disadvantages of Sheet Metal Fabrication
As sheet metal fabrication covers a wide area of techniques and methods, the advantages and limitations will vary depending on the process used during fabrication.
Benefits:
i. Sheet metal fabrication is fast and can produce high-quality components.
i. A large number of processes are available with wide range of materials
ii. High strength to weight ratio for sheet metal fabricated parts.
Disadvantage:
i. Each fabrication process has their own limitations.
ii. High initial cost for set up of equipment and tools.
iii. Requirement of skilled labors for each process.
