From a 50 Ton hydroforming press for university research to a 2000 Ton production press for manufacturing, ITC’s hydroforming systems fill a variety of needs. Customers choose from one of our standard hydroform systems or ITC can build a custom system for your specific application. ITC presses provide closed loop control of forces, motions and pressures to produce high quality parts. Our exclusive, easy-to-use software allows users to develop complex force, motion and pressure profiles for consistent tube forming applications. The system is comprised of five sub-systems: ● A single-acting, servo-controlled hydraulic press with mode switching during the process. ● Servo-controlled Hydroforming Feed Actuators that are fully integrated. ● A Servo-controlled Pressure Intensifier with pressure control valves. A variety of pressure and flow options are available. ● Interlaken designed tooling with changeable die inserts for differing cavity shapes that can be run with or without end feed. ● A B&R PC/Controller with 3rd generation Intel i7 processor. Benefits Specifications HEATform™ Interlaken has taken its vast knowledge of Hydroform press design and combined it with the innovative forming techniques developed by HEATform™. HEATform™ is Hot Metal Gas Forming, and the press and forming system components are an analog to traditional fluid hydroforming. Instead of hydraulic pressure, gas pressure is used to form alloys in a heat softened state. Molds are opened and closed by the main press actuator as in fluid hydroforming, but the addition of temperature allows parts to be made using far less force. Highly accurate control over temperature, pressure, and force application enable the HEATform™ process to provide shapes and feature details never imagined in traditional cold metal forming using almost any metal alloy. HEATform’s™ simple, production proven process is robust and repeatable, providing quality at competitive prices. Compared to Hydroforming: ● Expansion or forming ratio limits of typical hydroformed parts are no longer a significant design constraint. ● Choose your product material to meet your needs rather than for its formability characteristics. ● Economical tools focus on forming parts rather than controlling massive forming pressures. ● Ability to control wall thickness optimizes raw material use and final product weight. ● Combine parts and eliminate assembly steps with the innovative geometries possible with HEATform™ ● Familiar system subcomponents integrated in an innovative manner enable installation without significant plant upgrades or expansion. Specifications Bellows Forming Bellows are tubular designs that can absorb thermal and mechanical movements in pipe and duct systems. They are single or multi-layered metal cylinders formed into uniform corrugations or convolutes. A Bellows form can be produced in a hydroforming press using a variety of alloys, particularly those with good elongation. The metal tube is placed inside the desired Bellows shaped tooling and the ends are sealed by feed actuators. The forming fluid is forced into the part under pressure, causing the metal to expand and assume the convoluted shape of the die. A bellows is defined by the following terms: Pitch, (q) Convolution height, (w) Thickness, (t) Number of plies, (n) Bellows convoluted length, (Lb) Skirt length, (Lt) Bellows inside diameter, (Db) Dent Tester The Interlaken Technology Dent Test System provides the operator with the ability to evaluate the dent resistance of material specimens from something as simple as a 9" “pie pan” type specimen to full body panels and even complete automobiles. This machine allows the operator to do static testing in completely automated fashion. A punch applies forces up to 1100 lbs., speeds up to 100 inches/second and a punch travel of 2″. A large work area of 10′ by 12′ enables the dent tester to accommodate full size automotive panels or sheet stock for testing. The operation of the system consists of the following steps: 1. The indenter head is positioned manually to control the height, horizontal position and angle of rotation of the head. 2. Input parameters such as test speed, panel type, vehicle model, material ID, gauge, operator and project number are entered into the computer. 3. The operator tells the test to run. 4. The control software applies the appropriate loads and the appropriate speeds, incrementing the load and displacements. The software displays and records the appropriate data while the test is running. The system is available with a simple pedestal mount as shown at right. Indenter mechanism swivels and rotates to allow convenient positioning. Bend Tester The Interlaken 90° Bend Tester is a triple acting, servo controlled, hydraulic system used for metal formability testing. The triple actions are comprised of two linear actuators set 90° from one another and a rotary actuator set on center, where the two linear intersect. The rotary height is adjustable to allow the tangents of the outside of the roller to touch the centerlines of the linear actuators. Each linear actuator is a double-end actuator with its own load cell. These axes utilize force and position sensors and can be independently controlled using either force or position as a feedback. This system is comprised of a main loading frame and Hydraulic Power Supply. The HPS provides the hydraulic pressure for the Left, Right and Rotary feeds. The Hydraulic Service Manifold (HSM) and Servo Manifold provide the local servo control and pressure accumulation for the actuators, as well as safety blocking and pressure isolation. The typical work that is done on sheet metal samples is a clamping operation on each end of the sample strip, then a 90° pull over a rolling or fixed bead that can be heated to 400° F. The Bend Tester is able to run samples up to 2″ wide and has a travel of 10″ at forces up to 11,000 lbs. Draw Bead Simulator The Interlaken Draw Bead Simulator (DBS) System is a two axis hydraulic system used for friction testing on sheet metals. There are two hydraulic actuators positioned at a 90 degree angle. The Bead actuator provides the draw bead loading, which forces the draw beads together either squeezing the sample or providing a prescribed clearance with a roller tool. The Draw actuator provides the draw force to pull the sheet metal specimen through the draw beads. Both actuators utilize force sensors and the draw actuator also utilizes a position sensor. The two actuators can be independently controlled using either force, or position if available, as a feedback. The typical work that is done on sheet metal samples is a clamping operation on one end of the specimen strip, while the Bead actuator forces the draw bead tooling together over the opposite end of the strip. The Draw actuator then pulls the specimen strip through the draw bead tooling one time. Autofrettage The Autofrettage technique is used on thick walled metal tubes or components, to improve the durability of the part by creating a compressive residual stress at the bore. It dictates a pressure that is high enough to plastically deform the bore of the part, but not so high that it bursts the part. The pressure is applied to the inside of the tube. The result after the pressure is removed, is the elastic recovery of the outer wall puts the inner wall into compression, providing a residual compressive stress. The main reason to autofrettage a part is to increase its fatigue life. The applications are typically heavy walled tubes that experience cyclic loading and are thus prone to fatigue. Applications where this process is used include diesel engine components such as fuel rails and fuel lines, hydraulic cylinders, oil field components and waterjet components such as cylinders and check valves. The Interlaken system has a pressure intensifier rated for pressure up to 100,000 psi, a computerized control system with autofrettage software, custom designed tooling for your specific part, and a hydraulic power supply. We rely on partnerships and long-term relationships. We work with exclusive technology to form impossible shapes and achieve extreme part consistency. We’ll make it, or we’ll help you make it.
