Once you decide to buy new shearing equipment, you want to make sure you get the machine that fits your needs. Every piece and part play into production success. While these components may vary to some degree on each machine, they are great parts in sheet metal shearing machine. Here are features to consider when shopping for hydraulic shear for sale:
Make sure your mainframe is strong and durable. The mainframe of your hydraulic shearing machine is the “backbone” of its operation. This frame is what supports the entirety of the machine like the drive system, bed, and other components. If the frame is bent, broken, or even weakened due to engineering or usage, it’s something you want to be aware of. Some sheet metal shearing machines have “lightweight” frames that can crack, fracture, or break sooner than their heavy-duty counterparts. Check to see if the shear you’re wanting to buy has a lightweight or heavy-duty frame. Make sure the mainframe you choose fits your needs.
The bed of hydraulic shear for sale is where the operator will work and feed the material into the blades. The bed is the support for both the shearing blade and the material. The bed supports the blade and the material as it gets fed into the machine. It’s important that your bed is heavy and stable so that it can support the blade, material, and operation requirements.
As the name suggests, the squaring arm is used to squares up the material - cut material at 90 degrees. A squaring arm needs to be secure and accurate. Take a look at the engineering and manufacturing of the arm to get a better idea of whether or not it will work for you. Some arms offer measurement guides to make it easier for material management on the bed. Moreover, the squaring arm needs to equal to or longer than the length of the shearing blade, which will help you when you need some working room around the blade.
The hold down is what holds the material in place for the shear to bend or cut it. The hydraulic shearing machine has single or multiple bar clamps to hold the material firmly in place. The hold down is typically near the shearing blade to prevent movement or tipping during the cut. Typically, the higher force of a cut paired with more hold-downs gives a cleaner, more accurate cut.
The cutting blades are typically tool steel and hardened for wear resistance, as well as ground for sharpness. These blades are mounted on the upper moving ram and the lower fixed bed. Typically, they have gapped a few thousandths of an inch apart. What’s great is that the blades can be flipped — similar to tires being rotated — to combat wear, as well as resharpened or replaced. Moreover, you need to know the blade being the proper size and function for your type of operation.
Make sure your sheet metal shearing machine includes a measurement system or called “stops.” These assist operators in making consistent, quick, efficient cuts with accuracy so that they don’t have to manually measure each cut they make. Usually, these gages or stops are at the rear of the hydraulic shear machine to assist the operator and can be adjusted as needed.
The simple shear uses a hand wheel with manual operation in conjunction with a clutch-foot pedal. The more advanced equipment is programmable and offers your operator relief from manual control. Make sure your hydraulic shearing machine is which operation before you buy.
