DESCRIPTION OF FOUR-COLUMN HYDRAULIC PRESS YQ32-630A
The four-column hydraulic press is designed for processing parts by pressure, suitable for the automotive industry, the production of household appliances and parts for light industry.
The bed of the four-column hydraulic press provides a structure of three beams, the main element is a steel welded structure. A movable traverse with eight guide bushings is fixed on the slider, which moves along four columns as guides. The hydraulic station is located on the side of the machine.
This press provides stroke adjustment, the hydraulic system is equipped with a built-in block of two-position valves. The electrical system is controlled by a relay or PLC.
The press has the ability to work in manual and semi-automatic mode.

How to choose a suitable hydraulic press for you?
<Eight Elements of Choosing a Hydraulic Press>
1、 Workbench size
The effective dimensions of the hydraulic press are: the distance between the left and right sides, and the distance between the front and back edges. The size of the workbench is determined based on the external dimensions of different products (molds). When a hydraulic press simultaneously presses (stretches) different sizes, it is determined based on the maximum size of the product (mold). In theory, the size of the product (mold) accounts for 70% -80% of the effective size of the workbench, and the specific situation is according to customer requirements.
2.Distance between the table and the slider
The opening size refers to the maximum distance from the top of the oil cylinder to the workbench. According to the different pressing (stretching) distances of different products, in order to maximize cost savings, it is sufficient to ensure a safety margin of 50MM-100MM remaining in the main cylinder of the pressing (stretching) product. It is also important to consider making it easier to remove the product after mold opening.
3、 Master cylinder stroke
The main cylinder stroke refers to the range of piston rod stroke, which should be less than the maximum stroke of the main cylinder to prevent damage to the cylinder.
4、 Mold height
The clamping height refers to the maximum opening height minus the stroke of the main cylinder. The clamping height should be less than the height of the product (mold) after molding. For example, if the opening height is 900MM, the stroke of the main cylinder is 600MM, and the clamping height is 300MM, that is, the height of the product (mold) should be greater than 300MM.
5、 Height of workbench above ground
Normal 600MM-750MM, with different requirements for different processes, the height above the ground plus the height of the product (mold) ensures safe and comfortable operation for workers.
6、 Working speed
The speed of hydraulic presses can be divided into slow, fast, and high-speed. The selection of speed depends on the product process.
7、 Action requirements
The actions are divided into: pressing and stretching, stretching products, and demolding processes, which require the installation of a top cylinder. The operation methods are divided into manual and automatic.
8、 Throat depth dimension
The throat depth dimension refers to the distance from the middle point of the hydraulic cylinder to the wall panel. The throat depth dimension is determined based on the size of the product (mold), and should be greater than the radius of the product (mold) to ensure that the center point of the product (mold) is perpendicular to the center point of the hydraulic cylinder when working on the hydraulic press workbench.
