Applications and properties of the punching press machine
The punching press machine widely use in pressing and shaping electronics, communications, computers,
household appliances, furniture, transport (cars, motorcycles, bicycles), metal parts, etc.
High rigidity, high precision stand, accept steel sheet welding and heat treatment to remove physical
physical strength so that work equipment is sustainable in the long term and does not deform. b) uniforms
structural load, steel balance.
Strong high accuracy
The most important parts of the equipment such as the crankshaft, gear, transmission shaft and other parts are
Hardened by heat treatment grinding process with high wear resistance, long strength,
to guarantee high requirements for accuracy and stability.
Reliable and safe operation
The reason why it is easy to operate, the correct placement with the brake is different from the traditional one.
The clutch / brake combination device has a high sensitivity in combination with an international top
equipment common double solenoid control valve and overload protection device to guarantee a blow
high-speed sliding movement and precise and safe stopping.
Automated production, labor savings and high efficiency

After work
The punching machine can be used with a corresponding automatic feeding device with a feeding error
detection, pre-cut, pre-break equipment, fully implement automated production with low cost and high efficiency.
5. Slider adjustment mechanism
The slider setting is divided into manual setting and electrical setting, convenient and reliable, safe,
fast, accurate to 0.1 mm.
New design, environmental protection
Utilizes advanced technologies and design concepts in Japan and Taiwan, with low noise and low noise
consumption, no pollution benefits. Classification of punching machines.
According to driving force
The driving force of the slider can be divided into mechanical and hydraulic, ie according to the driving use
press power is divided into:
Mechanical pressure press
Hydraulic press
The most common processing by sheet metal pressing using a mechanical punch.
According to the use of different fluids, the hydraulic press is divided into a pressure press for oil and water
press punch.
The use of an oil pressure press is the cause of most, while a pressure water punch is used for the giant
machines or special machines.
rider’s movement
It can divide into single-acting, double-acting, three-acting presses,
most people only use a single action strike. Double movement and three-stroke strike commonly used for bodywork and large dimensions parts, the number is very small, sliding mechanism.
Crank press
A press that uses a crank mechanism is called a crank punch, usually a mechanical punch.
uses this mechanism.
The reason for using the crankshaft mechanism is its easy production and the possibility of repair
Determine the lower end of the stroke and the sliding activity curve differently
editing.
Therefore, this type of stamping is used for punching, bending, drawing, hot forging, intermediate temperatures.
forges, cold forges and almost all further pressing processing.
Clickless press
No crankshaft punch, also known as eccentric gear punch.
Better rigidity, lubrication, appearance and maintenance of the eccentric punch structure
then the crankshaft design. The disadvantage is the higher price.
An eccentric gear punch is more advantageous for high strokes. And a special machine for strokes
shorter is better for the crankshaft punch.
The crank punch therefore also includes a small punch and a high-speed punching press.
Articulated press
The use of a switching mechanism on a sliding drive is called tipping punching.
This punch has a unique driver activity curve with a very low speed (and crankshaft punch) nearby
low center of death and also correctly determines the term under the stroke. Therefore, this die is suitable for relieving and completing the pressing process for which it is commonly use
now blacksmiths are studying.
Friction press
The use of a friction transmission and a screw mechanism to track the punch is called friction
fire.
This punch is the most suitable forging, crushing operation. It can also used for bending, shaping,
stretching and further processing, with multifunctional function, thanks to the low price is widespread
used for war.
Because it is not possible to determine the lower end of the stroke, the machining accuracy is poor
Production speed is slow, the error in the operation control will gain too much weight, it is necessary to use skillful.
technical shortcomings are now gradually being rectified.
Screw press
In the sliding drive mechanism, it uses a screw mechanism known as a helical punch (or screw punch). (6) Stand press.
The use of a comb mechanism and a pinion of a slide drive mechanism is called a comb punch.
The spiral punch and the ridge punch have almost the same properties and are almost identical to the hydraulic ones.
fire
Formerly used for holding sleeves, punches, and other extruded articles, oil extraction, packaging,
and shell extrusion (thin hot stamping processing), but has now been replaced by a hydraulic
press if you are no longer using a very special situation.
Link Press
In a slider drive mechanism using various punch interconnect mechanisms. It call a rod-type punch.
When using a coupling mechanism. The stretching speed keep within limits as long as a drawing is available.
created and the drawing speed will be reduced by reducing the speed of the drawing process,
and the approaching top dead center stroke to the starting processing point is accelerated
the return rate from high dead center is faster than the crankshaft punch to increase productivity. This punch has long been used to deepen the cylindrical vessel, the bed.
The surface is narrow and is used to process the main body red.
Cam Press
A punch press that uses a cam mechanism on a sliding drive mechanism called a cam punch.
The punch shown in a well-shaped cam shape for easy retrieval of the desired rider
activity curve.
But the nature of the cam mechanism is difficult to express with more effort, so this punching capacity is quite
small.
Structures of punching machine molds.
Upper form
The upper mold is the upper half of the whole mold, i.e. the part of the mold on the press carriage.
Upper base of the mold
The upper base of the mold is the plate-like parts of the upper part of the mold, the workpiece close

Low mold
The lower mold is the lower half of the entire die, i.e. the part of the die adheres to the work surface of the die.

Blade wall
The wall edge is the side wall of the die hole.
Leading edge
The slope of the edge is the slope on both sides of the die hole.
air cushion
