This section provides an overview for hydraulic hole punchers as well as their applications and principles. Also, please take a look at the list of 9 hydraulic hole puncher manufacturers and their company rankings.
A hydraulic hole puncher is a tool for drilling holes using a hydraulic pump. It is suitable for drilling slightly larger holes. Both manual and electric types are available, and both are operated hydraulically, so they do not require a lot of force. It can drill holes in mild steel and stainless steel. The shapes of steel to be drilled include flat bar, equal-sided mountain steel, grooved steel, ripped grooved steel, and H-shaped steel.
The manual type is for steel thinner than 3.2 mm. It is smaller and more portable than the electric type. However, the electric type is more powerful than the manual type.
Hydraulic hole punchers are used in electrical construction for drilling holes for distribution boards, pull boxes, and piping. They are more convenient than drills, because drilling is quicker and requires less force. It is often used in equipment construction, but recently it is also being used in DIY projects.
For drilling large diameter holes, a manual puncher is more suitable than an electric hydraulic hole puncher. Also, if the application requires carrying, a manual hydraulic hole punchers are used. However, if the steel is thick, the electric puncher has more power.
Hydraulic hole punchers are machine that drills holes in mild steel or stainless steel plates. The punch and die are placed against the steel plate to be punched, and hydraulic pressure is applied from above to punch the holes.
The steel plate to be drilled is pre-drilled and set so that it is perpendicular to the punch. If it is tilted, the force will not be applied evenly and the hole may not open cleanly. There are different types of dies and punches, such as for round holes and long holes, and select the one within the applicable range for the shape and size of the hole to be drilled, the thickness of the target steel, and other factors.
In the case of electric, when the switch is pressed, the piston moves forward and the steel plate comes into contact with the punch attached to the piston and is gradually deformed and sheared. In the case of manual operation, repeated movement of the handle causes shearing. As the punch is pushed in, shearing begins from the underside as well, following the shape of the mounted die below, and a hole is opened. Scum accumulates inside the die.
In the case of electric operation, care must be taken to avoid ignition, explosion, and electric shock, and especially to prevent clothing and other objects from being caught in the process. Also, do not block the wind window.
