Selection of the size of the hydraulic press table
Today talk about the size of the hydraulic press table
We use a hydraulic press to pressurize any workpiece to deform it into the shape we need. The use of molds is inseparable here. The quality of the mold determines the standard of the pressed object is not standard, so how do we determine What is the size of the working surface of the hydraulic press and the size of the pressure?
This can be determined by precise scientific calculations and work experience. First of all, the pressure of the main cylinder of the hydraulic press generally ranges from 100 tons to 200 tons, 315 tons, 400 tons, 500 tons, 630 tons, 800 tons and 1000 tons. The thickness of the desired object and the size of the mold determine the tonnage of the four-column hydraulic press. We made a decision through scientific calculations and experienced workers. We want an item. His tonnage is a 630-ton machine. Then the next goal is to determine the size of the work surface according to the size of the mold. .
In principle, the mold is made of cast steel. It is a cube with various dimensions in length, width and height. Then how do we determine the size of the work surface? For example, our mold is 1 meter long x 1 meter wide, is it ours? The work surface can be placed 1 meter long by 1 meter wide, of course not. When the mold is placed on the work surface, at least two and a half centimeters of the lock nut must be vacant on both sides, and the position where the mold and the workbench are locked to each other must be vacated, that is, 1 meter × 1 meter. For the mold, the workbench you choose is at least 1m2×1m2.
Some of our purchasing manufacturers are one-sided pursuit of cost-effectiveness, lowering prices, and calculating the size of the work surface. Even if the mold cannot be placed in the future, or the fixed device cannot be installed after it is placed, the gain is not worth the loss. , A lock nut needs to take up 5 cm in length, two hand lock nuts need to be 10 cm in length, between the columns is a workbench with a length of 1 m 4, which actually only has a size of 1 m 3 on the workbench ×1m3, there is less than 10 cm invisibly. When we count the workbench, we must save it in advance. This is why we try to make it bigger when we choose the workbench. For this reason.
After talking about the work surface, let’s talk about the height of the opening and the stroke of the cylinder. When doing anything, the margin must be controlled. The height of the mold determines the stroke of the cylinder. The so-called opening height is when the slider is moved to the top. The height from the work surface is called the opening height, and the distance from the start of the cylinder to the top length to the longest position is called the cylinder stroke for short. The most important indicator of a hydraulic press is the size of the lifting pressure, the opening height of the work surface, the pressure holding time, the speed of fast up and down, and other factors.
