What are the common buffer devices of single-layer hot press?

Generally speaking, there are three common buffer devices of single-layer hot press, namely adjustable buffer device, gap buffer device and variable throttling buffer device. Glass fiber hot-press molding machine is a kind of electrical and mechanical connection device between parts and solder after heating two parts coated with solder flux in advance to a temperature sufficient to melt and flow solder. The effect of Suzhou hot press in the process of use is also very great, so the sales volume in the market is also quite good. According to the pulse heating principle of the hot press, due to the special design of the welding head surface, the resistance of the welding surface is very small, and the current will pass through the section with the minimum resistance. By constantly changing the voltage, adjusting the current level, and rapidly heating the welding head.
1. The adjustable buffer protection device, if it reaches a cylinder head through the buffer plunger, its oil return port will be blocked, and it can only be effectively throttled by itself, and its buffer working pressure will rise. This is because the piston is decelerating, such a buffer effect is not satisfactory. If the piston reverses, the pressure oil will flow from the check valve to the hydraulic cylinder, so the piston will open slowly. The buffer device can be adjusted by the enterprise according to the size of the opening.
The gap type buffer device of the invention has a large braking force at the beginning, but the braking force will drop immediately when the braking force does not work, the buffering efficiency is not very good, and the retarding pressure cannot be adjusted, but the structure is simple.
3. The variable throttling buffer device has three throttling grooves. The throttling area will increase and decrease with the increase of stroke. It will automatically adjust, so the buffer effect is very uniform and the impact force is very small, but its structure is very complex.
