By analyzing its schematic diagram, the first step after the pressure oil enters the cylinder pushes the plunger upward. The inner cavity forms a pressure. The second step is to push the one-way cone valve to drive the cup-shaped plunger to seal the oil hole channel at the bottom of the cylinder. The third step is three-dimensional printing. Push the check valve to the bottom of the plunger to form a second boost! The first step is normal, so is the second step normal? When you step on the paper presser, insert a screwdriver into the oil hole at the bottom of the cylinder. As a result, you can easily pass through the opposite oil hole. Obviously, the cup-shaped plunger does not work well after the post-press equipment. The problem lies here. After disassembling the cylinder, it was found that a small compression spring of the one-way cone valve was crushed. The relevant parameters are D9mm and d15mm. As for T and H love Kefa, it is unknown, because of various reasons can not get the original compression spring accessories and their corresponding parameters, we had to D9mm. The elasticity of the small compression spring is a key factor in the history of development! It is necessary to overcome the pressure of the tower-shaped large compression spring to make the cup-shaped plunger work in place. And it must be able to overcome the pressure oil and push the one-way cone valve. If the small compression spring is too small, the plunger will not work properly, and the paper press will also have a front failure! If the elasticity is too large, the pressure oil cannot push the one-way poppet valve for proofing, and the second supercharging is impossible to talk about. Later, D9mm is used. d15mm. T25mm, H45mm compression spring. The work of the paper press is back to normal, and there is no analysis and processing of the plates! The working process of Shenweida QZK1150A paper cutter is die-cutting hot stamping and indentation. After the paper pusher is in place, place the cutting object. First press the paper presser pedal to test the pressure, and then press the cutting button with both hands. Solid wood veneer as the main raw material, through high-frequency pressing and chairs made of different shapes. Bentwood chairs seat curved wooden multilayer board selected environmental pressing at high frequency, double-sided high-quality bendable fire board; election steel chair legs, powder coated or plated trim. Currently on the market 75% of bentwood chairs are curved wood and metal combination, modeling relatively simple, stylish. High seat bentwood chairs is very particular about, usually should be maintained at between 420-440mm, and bentwood chairs in to the desktop height should be maintained at between 280-320mm. Furthermore width should not be less than the former seat bentwood chairs of 380mm, seat depth between 340-420mm, the total height of the backrest is appropriate between 850-1000mm.
