Press Brake
A press brake otherwise known as brake press or brake is typically defined as a machine or equipment used for bending sheet metal. Basically, a press brake is described using two parameters – working length and force or tonnage. Who can operate the machine would depend on one’s knowledge and skill about press brake as this cannot be done by an ordinary and inexperienced person in the field.
Different types of Press Brake
Different types of press brake classified according to force or tonnage are: mechanical, pneumatic, hydraulic, and servo-electric. A mechanical press is advantageous in terms of speed and accuracy. Pneumatic and servo-electric machines, on the other hand are used for lower tonnage work or applications. Furthermore, hydraulic brakes are used to produce high quality products that are reliable and use little energy.Die Designs for Press Brake
A press brake is very useful for sheet metal bending. The produced sheet metal afterwards will then be useful for a wide array of applications in the manufacturing industry. From home appliances, to vehicles, to heavy equipment, these sheet metals are sure to be functional on everyday lives of people. But before the right sheet metals are formed, sheet metal benders should first consider the right die design to produce the right sheet metal.
There are several types of dies available in the market today: (1) V-dies; (2) rotary bending dies; (3) 90 degree dies; (4) acute angle dies; (5) Gooseneck dies; (6) offset dies; (7) hemming dies; (8) seaming dies; (9) radius dies; (10) beading dies; (11) curling dies; (12) tube and pipe-forming dies; (13) four-way die blocks; (14) channel-forming dies; (15) U-bend dies; (16) box forming dies; (17) corrugating dies; (18) multiple-bend dies; and (19) rocker-type dies.
Depending upon the requirement or your need, you can choose from the different die designs for your press brake mentioned above. The most commonly used die is the V-dies. These dies are widely used because they have different bottom dies with differently sized die-openings to produce a variety of materials and bend at different angles. The other types of dies have their own specifications and work in different ways to handle different kinds of metal depending on thickness, bend angles and form. For a detailed explanation of each of the different types of dies, you can read and surf the internet.
Press Brake Prices
If you are in the market to buy press bakes, it makes sense for you to gain a better understanding of what some of the recent prices for these products are. To help you understand, here are some of the best prices we have been able to find on websites such as amazon / ebay / specialty press brake stores.
- NorthStar Press Brake For 40-Ton Shop Press: $379 (Amazon)
- Malco MB48A 48-inch Portable Brake: $309 (Amazon)
- Torin Hydraulic Shop Press – 20-Ton, Model# T52001B: $299 (Amazon)
Through our experience, it makes sense for you to pay $300 or above for a quality press brake. While you can find some at prices under these prices, you need to understand that you may suffer later as the lifespan of these products won’t be as great as the higher prices. Likewise, don’t feel obligated to spend over $1000 for your product. The best products seem to range from $300 – $700.
Recent Improvements in Press Brake Technology
Mechanical brakes dominated the world market until the 1950s. Afterwards, hydraulic machines have been popular in the introduction of better hydraulics and incorporation of computer controls of press brake. Furthermore, recent improvements in the press brake industry revolve around the controls and the device called backgauge. The latter is used to position accurately the piece of metal such that the press brake puts the bend in the correct place. Improvements on this device help in developing or forming complex parts in metal sheets. Press brake nowadays has multi-axis computer controlled backgauges and optical sensors. The optical sensors aid the operators in making adjustments during the bending process. These optical sensors are also able to send real-time data about the bending angle to machine controls that can adjust process parameters.
