Factory direct punch presses, forging machine ZDM Zhejiang forging presses JZ21-63B open fixed bench presses 63 tons presses, Zhejiang Metalforming Machinery Group Co., Ltd. of the domestic open fixed bench presses are the major producers, the production of ZDM brand mechanical pressure machine is 10 years of brand-name products in Zhejiang integrity, quality assurance http://zdmmachinery.1688.com/ The series has 10 models :( nominal power range 250-4000kN) JZ21-25B JZ21-45B JZ21-63B JZ21- 80B JZ21-110B JZ21-125A JZ21-160B JZ21-200B JZ21-200S JZ21-250B JZ21-315B JZ21-400A details can be found on our website www.zheduan.com ------------- -------------------------------------------------- ----------------- structural characteristics of Zhejiang forging presses JZ21-25B ZDM open fixed bench presses forging machine high-performance presses 1, the reference to Japan's advanced machine tools models design, beautiful appearance, unique structure. With the overall structure of steel plate welded by a large furnace tempering, eliminate stress, with sufficient angular stiffness and rigidity line to ensure that the performance of the machine. 2, the crankshaft vertical put, just good strength, gear oil infiltration in closed pool, lower noise. 3, using the six-sided rectangular slide rails, and after quenching, the guide is good, and to maintain good accuracy. 4, the use of advanced fully sealed wet-pneumatic friction clutch - brakes, reliable, stable operation, no dust, low noise, long life, in line with environmental requirements. 5, using sensitive hydraulic overload protection device, overload the pump used in Taiwan "KING AIR" whole package, to ensure the safety of the machine and mold. 6, using the Japanese "OMRON" Programmable Logic Controller (PLC), "SIEMENS" exchanges and contacts, push button switches and other Schneider TE, to ensure the reliability of the machine. 7, using eight security settings, by electric double-loop control, multiple interlocking design to ensure safe operation. Double solenoid valve by the United States "ROSS" brand. 8, stepless slide stroke frequency, using electromagnetic slip speed motor. To switch frequency control, optional Japan "FUJI" other inverter and braking unit (required for ordering). 9, the configuration enclosed numerical display device and electric height adjustment device, easy installation and adjustment of the mold. 10, 1100kN and above products used by the US-owned Nanjing "BIJUR" or the Sino-Japanese joint venture Yongjia "flow through" and other electric automatic lubrication system. 11, the configuration of Nanjing Eston electronic / mechanical cam controller, enabling travel jog and stop at any position. 12, all devices except devices listed in the "main outsourcing parts list" and some optional devices, all of its own production by Zhejiang forging machine tool plant, no Waixiejiagong. The use of brand-name steel plate, welded steel bed part all use completely new material, old material or waste without using splicing.
