Owing to our expertise in this domain, we are engaged in manufacturing and supplying a wide range of Dry Drawing Blocks OT6/BB type. The offered range is widely used for stainless steel, high carbon steel, alloy steel, mild steel and copper wire drawing in wire industry. Our offered range is designed as per the technical advancements by following the guidelines of experts. These are fabricated using the best grade raw material and sophisticated technology in accordance with the international quality standards. Available in various specifications so as to cater to clients’ wide needs, these are stringently tested by our quality controllers on various parameters in order to ensure flawlessness. Mechanism: The wire is drawn through a die which is fitted in independent water cooled die box It is further accumulated on the block, and later being taken through the OTO pulley to the next die Specifications: This BB block is a twist free type machine with free drum block for accumulation and transfer to next block for higher speed & better finish products.

Machine is designed to operate continuously. First block is provided OTO type for wire accumulation, allowing forth removal of any rod, snarl or changeover of coils at feeding end. VFN system on OTO block keeps uniform tension of wire passing over with on jerks. Each block is equipped with pressure regulating valves and gauges for accurate control of air pressure on sensor arm. Separate manifolds are provided for water to drums and dies with regulating valve on each block.BLOCK AND COOLING SYSTEM: Drawing drums are forged alloy steel, fully hardened and ground. Surface hardness: 58-60 HRC. Drums are internally water cooled with narrow gap system. Complete wetting of wall by highly turbulent motion of water, higher cooling effect with increasing drawing speeds. Drums are externally cooled by air from a single common blower through duct forming part of machine frame.DIE BOXES: Dies are direct water cooled from a separate manifold. Dies are loaded from top for quick fixing. Motorized rotating die holders can be provided; extra long to adopt standard pressure dies. Die boxes are equipped with motorized lubricant stirrer. Rotating die holders have single motor for stirrer and holder. Die boxes are adjustable in horizontal and vertical plane for cast and helix adjustment of wire. Die boxes are suitable for dry lubricants, large enough to store sufficient quantity of lubricant.SPEED CONTROL: Speed regulation of each block is achieved through self cantering sensor arm on which the wire is guided.SAFETY GUARD: Well balanced sheet metal guards, with transparent sheet/wire mesh to see through condition of machine, are provided. Guards are electrically interlocked not to allow running of machine with open guards. Sound proof guard for low noise level with suction of burnt powder can be provided.TRANSMISSION: Motion transmission from motor to block shaft is achieved directly by V belt and pulleys or through helical gear arrangement.INTELLIGENT CONTROLS: Specially designed A.C. Three Phase Inverter Duty/Servo Motors L&T Supernova/Siemens 1ph7 constant torque up to base speed and constant power above base speed. Digital A.C. Three Phase Vector Flux Inverter Drives ABB ACS 800/Siemens Kinemics provide the system with fastest communication through provirus. All blocks are working with a range of encoder feedback, thermal protection, and flux vector controlled. The logic control is attained automatically by PLC system (Siemens) automatically calculating reduction rate and monitoring all related dates.Utmost control flexibility allows any drafting programme and drum skipping. HMI displays all function data making it easier for the operator to take control of the machine during production. Displays and memorizes the fault for easy diagnosis. Can be interfaced with remote computer to collect all information. Cubicles are sheet steel enclosures with IP54 protection, duly power coated and with exhaust. Electric control system provides a smooth acceleration from zero to pre-selected value. Normal stop is attained with ramp down control within 15 to 30 second. Emergency stop/quick stop is attained within 6 to 8 seconds. This can be achieved without a broken wire.

Straight Line Wire Drawing Machines were developed for straight or deflection free drawing of wire to provide better drawability, lower frictional contact and lower operator interference. Theoretically there is no limit as far as the wire material or wire diameter is concerned to be drawn on these machines. ASSOMAC has pioneered to indigenously develop the Straight-Line Wire Drawing Machine Technology in India. Presently the range available is capstan diameter 900mm, 750mm, 600mm, 550mm, 500mm, 460mm, 400mm and 300mm for inlet wire diameter 16mm down to 0.5mm. Line speeds upto 25 Mtrs / Sec. These heavy Straight Line Wire Drawing Machines provide remarkable drawing performance for Low, Medium and High Carbon Steel Wire, Stainless Steel Wire and special Alloy Steel Wire and Non-Ferrous Alloy Steel Wire. This machine has a sensor roller between the drum and the next die such that the wire passes in contact with this roller. These rollers have sensors to detect the position of the arm and maintain tension on the wire by regulating speed of the drums. The drums of this machine are inclined to the vertical axis to effect fill on the drums. Principally this machine is best suited for thick wires. Features of Straight Line Wire Drawing Machine: Machines are built on modular structure, in combination of Blocks and do not require any special foundation. Better productivity due to higher drawing speeds, twist-free operation & better cooling. Easy operation and faster threading. High pressure Narrow gap, internal water cooling for high efficiency cooling of wire. High degree of reliability, low downtime due to lower no. of wear parts. Much better finish wire quality due to a gentler handling of the wire during the drawing process (less wire deviations, low torsion etc.) as well as an optimized wire cooling. Highly effective pneumatic braking system in case of emergency. Better environmental conditions due to increased dust protection. Greater flexibility and lower current consumption due to modern AC drive technology and efficient power transmission system. PLC based control with profibus digital communication and fault diagnostic system. Optional Fitment: Stripper Block Rotating Die Boxes Motorized Soap Applicator Die Boxes Die less drawing trough Rolling Cassette Laser wire diameter measurement system Dust Suction System Online Modem based PLC support
