Pneumatic punch involve a series of basic processes in the process of sheet metal stamping,which together complete the transformation from raw materials to finished products.The following is a detailed introduction to the basic process of sheet metal stamping by
China pneumatic punch manufacturers:
一、Material dropping and punching
1.Material cutting:Material cutting is a type of punching,which refers to the process of using a die to punch out parts or blanks of the desired shape from a sheet metal,while also punching out excess material.On Pneumatic punch,by adjusting the mold and stamping parameters,it is possible to accurately punch out parts of the desired shape and size.
2.Punching:Punching is the process of punching holes in sheet metal.On the pneumatic punch press,the punching die is installed on the punch press to form the required holes on the sheet metal through punching action.The size,shape,and position of punching can be precisely controlled through mold design.
二、Bending
Bending is the process of bending sheet metal into a certain angle and shape along a certain direction.On Pneumatic punch,bending molds are used to achieve this goal.By adjusting the shape of the mold and stamping parameters,the bending angle,radius,and shape can be controlled to obtain the desired bent part.
三、Deep drawing
Deep drawing is a stamping process that draws flat materials into open hollow parts.On Pneumatic punch,the deep drawing die uses stamping action to draw the sheet metal into the desired shape and size.During the deep drawing process,it is necessary to control factors such as stamping speed,mold clearance,and lubrication conditions to ensure the quality of the drawn parts.
四、Flip up
Flanging is a stamping process that turns the edge of a hole or blank into a vertical edge.On a pneumatic punch press,the flanging die flips up the hole edge or edge through stamping action to form the desired vertical edge.The flanging process is commonly used to increase the strength and stiffness of parts,or for purposes such as connection and sealing.
五、Bulging shape
Bulging is a stamping deformation process that enlarges hollow or tubular parts inward or outward.On Pneumatic punch,the bulging mold causes hollow or tubular parts to undergo bulging deformation through stamping action,thereby obtaining the desired shape and size.The bulging process is commonly used to manufacture hollow parts with complex shapes.
六、Shrinking mouth
Shrinkage is a stamping process that reduces the diameter of the mouth of a hollow or tubular component.On Pneumatic punch,the shrinking die reduces the diameter of the mouth through stamping action,thereby obtaining the desired size and shape.The necking process is commonly used to manufacture tubular parts that require necking.
七、Cutting and trimming
1.Edge cutting:Edge cutting is the process of removing excess margin or burrs from the edge of a component.On Pneumatic punch,the trimming die cuts off the excess or burrs on the edge of the part through stamping action,making the edge of the part flat and smooth.
2.Trimming:Trimming is the process of smoothing the surface of a component.On Pneumatic punch,trimming molds or tools can be used to remove small defects,ripples,or burrs on the surface of parts,improving the surface quality of the parts.
In summary,Pneumatic punch involve basic processes such as material dropping and punching,bending,deep drawing,flanging,bulging,necking,as well as edge cutting and trimming in the process of sheet metal stamping.These processes collectively complete the transformation from raw materials to finished products and meet the needs of different parts manufacturing.
