Novel press machine adjusting device

Abstract

Provided is a novel press machine adjusting device. A closed positioning flange is arranged in the center of an eccentric bushing and is provided with a crankshaft, the crankshaft is provided with a limiting toothed ring and a two-position positioning key, the outer ends of the two sides of the eccentric bushing are provided with symmetrical double-fixing pressing boards, and the double-fixing pressing boards are fixed through double-position fixing bolts. The novel press machine adjusting device can overcome the defects that as the stroke is fixed, an existing press machine is narrow in process range and poor in technological adaptability; meanwhile, the defects that an existing press machine stroke adjusting mechanism is complex in structure, not convenient to adjust or maintain, poor in adjusting precision, difficult to assemble and disassemble, high in labor intensity, low in production efficiency and poor in universality are effectively overcome.

Description

technical field [0001] The invention relates to a press adjusting device, in particular to a novel press adjusting device, which belongs to the technical field of press configuration. Background technique [0002] The press adjustment device is an important configuration part of the press. The current press adjustment is determined by the eccentricity of the crankshaft. Therefore, its adjustment is also fixed. This fixed adjustment cannot be applied to multiple sets of molds. Exchange processing limits the scope of its process. Due to the limited scope of application, in order to adapt to the work of the mold and meet different process requirements, it is necessary to use a press with corresponding stroke parameters, which increases the investment in equipment. Increase the cost of production; although some existing mechanical presses also use adjustment mechanisms, the adjustment mechanism has complex structures, inconvenient adjustment, poor adjustment accuracy, and the me...

AI Technical Summary

Problems solved by technology

[0005] Beneficial effects of the present invention: In the present invention, as long as the fixing bolts are removed, the meshing relationship between the eccentric sleeve and the double-position positioning teeth is separated, and the position of the eccentric sleeve on the crankshaft is rotated, the relationship between the crankshaft journal and the eccentric sleeve can be adjusted. The eccentric distance between them can achieve the purpose of adjusting the press. Therefore, the present invention can overcome the defects of narrow process range and poor process adaptability caused by the fixed stroke of the existing press; at the same time, it can also effectively overcome the The existing press stroke adjustment mechanism has the defects of complex structure, inconvenient adjustment, poor adjustment accuracy, difficult disassembly, inconvenient maintenance, high labor intensity, low production efficiency, and poor versatility
