Forklift Support Base Lost Wax Investment Casting

Product Introduction

Forklift Support Frame Locking Mechanism
The utility model relates to a forklift for transportation, specifically a forklift support frame locking mechanism.
Forklifts are common mechanical equipment used in workshops to transport goods in daily production. Its working principle is to extend the bottom plate of the forklift under the goods on the shelf, and raise the height of the bottom plate through the cylinder device to contact the lower surface of the goods and lift the goods. Thus moving goods from one place to another. Generally speaking, the height adjustment of the forklift floor is realized by using a cylinder. The front end of the cylinder piston rod is connected to the floor support frame with an external thread. Because forklifts are often used to transport heavy goods and are used frequently, especially the forward and backward tilting movements during heavy-loading operations will put a great burden on the connection between the cylinder piston rod and the support frame of the bottom plate. The threaded connection of the cylinder piston rod can easily become loose due to wear. , causing the length of the piston rods on the left and right sides to be different, causing the base plate to tilt during the backward tilting process. In severe cases, the piston rod may separate from the support frame of the base plate, which brings great safety risks to daily production.
A forklift support frame locking mechanism, which includes a cylinder, a bottom plate support frame, and a bottom plate. It is characterized in that: a locking nut is installed at the connection between the piston rod of the cylinder and the bottom plate support frame, and the locking nut is installed outside the cylinder piston rod. At the thread, one shaft end face of the locking nut is in close contact with the shaft end face of the bottom plate support frame.
All locking nuts of the forklift are installed on the cylinder piston rod and the rear axle end face is flush.
beneficial effects
After the locking nut is installed on the cylinder piston rod, since one shaft end surface of the locking nut is flush with the shaft end surface of the bottom plate support frame, when loading heavy goods on the bottom plate, the freedom of movement of the piston rod in the direction of the bottom plate support frame is locked. The nut restricts the cylinder piston rod from moving in the direction of the base plate support frame, which avoids the danger of the base plate tilting due to different piston rod support lengths. When the threads are worn, the nut is also very convenient to replace.
 

Investment Casting Principles
Investment casting is a process for making castings by casting molten metal material into an investment mold. Compared with other casting processes, investment casting has the advantages of high precision, high surface finish, high material usage, and the ability to manufacture complex shapes. The four key links of investment casting will be introduced below.
1. Mold preparation
Investment molds are usually made of plaster, ceramics, wax and other materials, among which plaster molds and ceramic molds are widely used. The choice of mold depends on the metal material used, the size and shape of the Forklift support base lost wax investment casting, cost and other factors. The exhaust system designed inside the investment mold can effectively reduce the generation of pores.
2. Investment mold
The production principle of investment casting is to cast molten metal in an investment mold, and then remove the casting after cooling and solidification. In this process, the molten metal needs to fill the mold cavity in the investment mold to form the shape of the casting. At the same time, the temperature, fluidity, solidification speed and other parameters of the molten metal need to be controlled throughout the process to ensure the quality of the casting.
3. Casting cooling
Casting cooling is one of the important links in the investment casting process because it determines the dimensional accuracy and surface quality of the casting. The cooling rate may affect the formation of solid structure in the casting, and the cooling method should be determined based on the material and design specifications of the casting.
4.Heat treatment
Heat treatment is a step in investment casting. By heating the casting to a certain temperature and cooling it within a certain period of time, the microstructure and mechanical properties of the casting can be changed, its strength and toughness can be improved, and the casting requirements can be better met.
In summary, investment casting is a high-precision and casting process that has been widely used in the manufacturing field. With the continuous advancement and development of technology, investment casting will have broader application prospects.
