USA Wilson Press Brake Tools
Wilson Tool’s focus is to help their customers become more efficient. Whether it’s through setting up jobs more quickly, increasing performance or sustaining a leaner operation, the company offers several products to help customers.
One such product is Wilson’s Power Express Hydraulic Clamping System. This system will self-seat almost all American-style tooling without a self-seating groove.
“This is really nice. Say that you’re a customer, and you’re buying a new press brake. You have about 40 years of tooling sitting on the shelf, and you really want to use that tooling in your new brake, but you also want the functionality of self-seating,” comments Mike Sosnoski, press brake manufacturing manager.
“Well, you can buy this clamping system,and it will allow you to use your existing tooling to automatically self-seat in this clamping system.”
Wilson Tool also offers Express Clamps, a manual clamping solution for European-style tooling. Though it’s been on the market for about 10 years, Sosnoski notes that it’s still a high-selling product.
“It gives customers a lot of flexibility and freedom, and it’s a relatively low-cost solution,” he says.
The Express Clamping System is designed to work with European-style tooling. According to Wilson Tool’s website, when using the system, operators simply push long or sectionalized punches upward into the clamp and then lock them into place by pushing upward on the clamp’s removable lever, instead of having to slide the tooling in from the end of the brake. The clamp can then be unlocked by pushing down on the lever.
Wilson Tool also offers European-style staged tooling that features a common shut height, allowing staged bending to be performed on European-style press brakes. This reduces set-up time and increases productivity, as well as enhancing lean operations, since a number of different bends can be completed in one setup.
According to Wilson Tool’s website, the European-style tooling is precision ground to a tolerance of +/- 0.0008 in. and features common centerlines on all punches. Wilson Tool’s Nitrex surface enhancement is also applied to the tooling, providing a surface hardness of HRC-70 that increases durability and tooling life by several times when compared to non-treated tooling.
Another product that will potentially increase performance for customers is Wilson Tool’s quick-change large-radius punch holder.
“Let’s say that you have a half-meter ong punch holder, about 20 in.,” explains Sosnoski. “It’ll have three screws across the front, and to unlock and switch radiuses, you just take an Allen wrench, do a half turn on each of those three screws, slide the radius out, slide your next one in, give a half turn on each of those screws, and it’s locked in. It’s a quick-change feature that we think customers will be really excited about.”
The punch holder is also laser heat-treated, and the punch tips are Nitrexed. Sosnoski points out that this is added value, as most of the competition offers a product that is pre-hardened or soft. The advantage of the heat treatment is that it protects against burrs that might be found on laser-cut steel and would be abusive to a pre-hardened or soft product.
Wilson Tool also stocks 0.375-into 2-in.-radius tips for their punch holder and can accommodate special radiuses as well. If a customer needs to bend very close to the end of the sheet and produce small flanges, Wilson Tool has a solution for that problem in their V-Series Press Brake Dies.
The V-Series die works through what Sosnoski calls pivoting shoulders. As the punch tip pushes down and comes into contact with the paddles, the paddles will pivot and assist the sheet in bending.
“You’re not really drawing material over the shoulders of the die – the paddles of the die are moving with the sheet metal,” he says.
“Typically, with the flange you need so much material to come into contact with both shoulders of the die that you’re limited on the length of your flange. With the design of this V-Series die and the paddles that move, it’s really one flat surface. You can have very small flanges and bend with this, which is very attractive, because that’s one of the nemesis in the press brake world, how to deal with the short flanges.
The V-Series dies also assist with avoiding distortion in the bend and reducing sheet marking, both through the support provided by the pivoting
shoulders. Wilson Tool’s acquisition of Exacta in November 2010 further added to their capabilities.
“In the press brake world, Wilson Tool has always offered precision ground tooling, but now with the acquisition of Exacta, we’re able to offer the conventional plain milled tooling, as well,” comments Sosnoski.
“We can give the customer either option, and we’ll help them decide which is best for their application.”
Exacta also specializes in large equipment – they’ve produced punch holders measuring 4 ft. tall and hydraulically controlled dies 2 ft. wide and 60 ft. long. With its acquisition of the company, Wilson Tool now has this capability, too.
