Square Bar Bending Machine

Bending solid metal bars, particularly in round, half-round, square, hexagonal, or rectangular sections, is efficient. “Easy way” bending (y-y axis) forms a belt-like shape, while “hard way” bending (x-x axis) resembles a large washer. Bending flat bars the hard way is the most challenging. Bending bars into rings or segments is often more cost-effective than cutting from plates due to higher material yield. With expertise and proper equipment, various bars, including hot-rolled, stainless, aluminum, Inconel, brass, and copper, can be bent with minimal distortion.

Often square bar is machined after bending as an affordable alternative to cutting shapes from plates. Machining square bars after bending can indeed be a cost-effective alternative to cutting shapes from plates in certain scenarios. Here are some reasons why:

  • Material Efficiency: Using square bars reduces material wastage compared to cutting shapes from plates, as you’re starting with a form that closely matches the final shape required.
  • Reduced Processing Steps: Bending a square bar and then machining it can sometimes require fewer processing steps compared to cutting shapes from plates. This can lead to reduced manufacturing time and costs.
  • Simplified Tooling: Bending a square bar might require less complex tooling compared to cutting shapes from plates, especially for intricate or irregular shapes.
  • Material Availability: Square bars are often readily available in a variety of materials, sizes, and grades, which can simplify procurement and lead to shorter lead times.
  • Cost Savings: Overall, machining square bars after bending can lead to cost savings in terms of material, processing, and tooling compared to cutting shapes from plates, especially for smaller production runs or simpler geometries.

Square bars can only be bent as one style (i.e. there is no strong axis or weak axis to bend against). BIT Series Profile Bending Machine can ability to bend all mill produces sizes of square and round bars.

Square Bar

Bars are most commonly used for smaller manufactured parts and for industrial applications.

Bars can be bent with virtually every bending process we have available with our section bending machine. For very tight radius bending you can utilize a draw bending process where you must pull the material (draw the material) around a bend die matching the desired bend radius.

What is bending solid material

Bars are most commonly used for smaller manufactured parts and for industrial applications.

Square bars can only be bent as one style (i.e. there is no strong axis or weak axis to bend against).

BIT profile bending machine (section bending machine/hydraulic bar bending machine) can ability to bend all mill produces sizes of square and round bars, including aluminum, stainless, and carbon steel.

5 important factors affecting the square bar bending process

Several tips can help to ease the bending of square or rectangular material and reduce the amount of distortion in bent sections.

  • Method of Bending: This is a key factor in controlling distortion. A correctly chosen procedure can help to produce consistent tolerances and accurate parts. Generally, smaller material requires rotary draw bending or compression bending, which can incorporate wiper dies and mandrels. Induction and increment bending should be used with larger material bent to a larger radius. Design distortion and material size are important factors for determining the bending method.
  • In many cases: There is no better factor than experience. Many trained bending artisans know what is required to produce an acceptable product.
  • Size of Material: Larger material bent to a smaller radius has a greater chance to distort than smaller material bent to a larger radius. Design and planning are necessary to help solve bending problems before they arise.
  • Tooling: After the parts have been designed, the method of bending has been chosen, and procedures to bend to proper tolerances are established, the machine must be set up with the proper tooling. Based on design conditions, tooling that can be used includes bend die, clamp block, follower block, mandrel, and wiper die. All or some of this tooling may be required.
  • Internal and External Lubricant: Lubricants decrease the friction between tooling and material to be bent. When friction is reduced, material flows smoothly through the bending equipment, allowing the machinery to perform its designed operation efficiently.

Application

Bent square bar for trummle screen rings, architectural features, artistic works among others. Often square bar is machined after bending as an affordable alternative to cutting shapes from plate.

Bars are formed by either a cold-drawn process or a hot-drawn process. The different processes result in different material properties which are defined by local mills that are producing bars. Hot rolled bars are typically designated as A36 with a yield point (PSI) of 36,000 minimum. Cold rolled bars are typically designated as 1018 with a yield point (PSI) of 54,000 minimum.
