Punching Machine

Getting more done with a combo

The idea of combined punching and shearing machines has gained the approval of current generations. They allow operators to finish products through a single installation more accurately, performing relatively few steps without adding values.

In what ways can the combination of punch and shear operations be advantageous? 

Are the combined punching/shearing machines in competition with combined punching/laser machines?

Every single combined machine offers promotion in a particular field. The matter is not about competition, but the improvement of capability. 

For instance, during the laser cut process it takes quite long the sheets to get separated, yet, the combined punching/laser operations allow punching, forming tapping and contouring parts through a single step. If the task cannot be accomplished through punch operation, turn to laser cutting.

To make right-angled products such as an electric box, telecommunication data center or a cabinet, you will gain the utmost productiveness by making use of the combination punching and rectangular shearing machines. This allows operators to punch, form, and tap just like the combined punching and laser-cutting machines. But in this case component shearing is carried out with shaker part elimination. The separation of accomplished parts occurs in no time. 

Products of limited size, separate elements, lengthy pieces might need tap, mark, up-form operations through turrets. Next, they can be sent to shearing with no additional set-up.

What is the latest advancement in the combination of punching and shearing machines?

In the latest versions, shearing technologies are merged with servo-electrical driving systems. Shearing can be controlled and adjusted relatively easily out of the hydraulic system. This provides higher productivity. As the servo-electrical system delivers more economy, the expenses of the shearing operation have decreased by up to 50 %.

Servo-electrical systems offer not just the economy, but cleanliness as well. There are no disadvantages to the hydraulics including high-cost oils, filtering and maintaining issues. Chillers are not needed. There are no thermal variations.

What is the essence of the shear capacities? 

Every manufacturer offers a certain range of capacities. The combined shearing machine designed by HARSLE is capable of shearing aluminum sheets of 5mm thickness, cold-roll steels of 4 mm, stainless sheets of steel of 3mm thickness. Blades offered by these designs are 40 inches at the X-axles and 60 inches at the Y-axles. The frame of the shearer and the top blades, with rakes mounted on them, make it possible to shear too long parts eliminating any noticeable step mark. You can program as well as make automatic settings for optimal shear strokes and the gap between blades. 

What is the course of the work when the task is to have parts with no punch feature?

In this case, the workshop may apply a combined punching/shearing machine to pre-cut blanks to perform another operation. This means the workshop can gain standard-sized sheets and cut workpieces to size economically on their own.

What are the extra benefits brought to the workshop by the combined punching/shearing equipment?

Nowadays combined machines offer easier and more convenient use for operators compared to the previous designs. This is due to such advancement features as software and touchscreen controlling, which also speed up the work process. The performance of combination equipment is equivalent to the productiveness of 2 or 3 autonomous turret punches.

The integration of shearing in the combined equipment provides more total security compared to the autonomous shearing. The structural frame offers higher defense against blades. As the equipment is featured with safe operation, there is no need for extra protection measurements.

How to punch and shear a heavy material through one step?

Combined punch/shear equipment is not new in the production of structural steels. This was one of the 1st productions. The motive of it was worth its production, as shearing parts are less inexpensive when they have been punched or drilled than using plasma. The cost relation is the same as two or three cents for shearing parts in comparison with 1.25 dollars to plasma-cut a lineal foot.

Certainly, separate punch and shear machines are still used vastly. However, the demand for placing 6, 8 or 20 feet plates on the machines, with various capabilities, is increasing. This served as a reason for adding angular capacities.

Here are answers to some possible questions while using combined punching/shearing machines for structure materials.  

What are the major benefits of combined shearing/punching machines to build parts? 

First of all, the combination of punch/shear equipment shortens the time of processing the materials in order to transfer them from an operation to the other. The process is quicker, the costs involved are low. The combined versions provide laborious advantages. While shearing a part in the workshop, operators often have to raise and bring it to some other machine. This might bring about issues related to health and safe operation, which can be avoided in the case of processing fewer materials.

 In what way have punching/shearing capacities advanced?

Combining punch/shear operations has a long-year experience. Now our models are capable of drilling as well, enabling a user to perform drilling or tapping. Some other additions to our models include angular punching and shearing of plane bars. As to the structural production, these machines are completely capable of processing a truss bracing, angles of clips, sheet joints, etc.

Systems to mark and scribe are another addition to certain models. This allows adding a center-line indicator for holes to the plates. Imagine your task is welding plates to beams, it is possible to add each visual indicator prior to shearing without margins. Consequently, welders need no measuring. 

What about notching pieces?

Plane steel shears rotate in V550-6 to accomplish profiled sheets otherwise requiring plasma or burn technology for corner-cutting. Machines bearing rotate scissors cannot work with radius, but it can rotate, creating a 45-degree incision.

What are the differences in the service life of blades while making a comparison between autonomous and combined machines?

The differences are not of great significance concerning the matter. On the machines designed by us the bottom blades lower by nearly 1/8 inch, thus, as soon as the sheet moves to the shearing area, no obstacles occur preventing it from rubbing the blades. Once the sheet appears in the cut area, the bottom blade rises to the desired extent.

Plane scissors on our designs have a width of 20 inches. The power cylinder is located right at the loading points, which in turn excludes dirt and twisting. Each side of the angular shear might be used with particular radii to gain the desired results.
