Adjusting device for eccentric sleeve of wedge type hot die forging press

Abstract

The invention discloses an eccentric bushing adjusting device of a wedge type hot die forging press. The eccentric bushing adjusting device comprises a connecting rod, an upper clamping block, a lower clamping block, an eccentric bushing, a main sliding bearing, an upper pull rod, a lower pull rod, a locking drive device and an angle adjusting device. The locking drive device is a hydraulic cylinder or an air cylinder. A closed cavity formed by a cylinder body and an end cover is divided into a left cavity body and a right cavity body through a piston, a spring is arranged in the right cavity body, the cylinder body or the end cover is provided with a hole communicated with the left cavity body, and the bottom of the cylinder body is clamped between the upper clamping block and the lower clamping block. One end of the upper pull rod and one end of the lower pull rod are hinged to the piston through pin shafts, and the other end of the upper pull rod and the other end of the lower pull rod are hinged to the upper end face and the lower end face of a large head opening end through connecting pins respectively. The angle adjusting device comprises an angle adjusting driving device and a worm, worm wheel teeth are arranged on the outer surface of the eccentric bushing, a worm and worm wheel pair is formed by the eccentric bushing and the worm, and the angle adjusting driving device is in transmission connection with the worm and worm wheel pair. The structure is more compact, and the opening end of the connecting rod is stressed evenly and is not prone to deformation.

Description

technical field [0001] The invention relates to the field of forging equipment, in particular to a wedge-type hot die forging press. Background technique [0002] In recent years, due to the vigorous development of the automobile industry, especially the rapid increase in market demand for car parts, it has driven the rapid development of auto parts manufacturers. The market is also growing rapidly, and at the same time, the market's requirements for hot forging presses are also increasing. [0003] Such as figure 1 with image 3 As shown, in the wedge-type hot die forging press, since the small end of the connecting rod 01 is connected to the wedge 08, and the wedge 08 is connected to the slider, the crankshaft is installed at the center of the big end of the connecting rod 01, and the crankshaft is fixed. Rotating the eccentric sleeve 02 can change the center position of the big head of the connecting rod 01, thereby changing the length of the connecting rod 01, and fin...

Problems solved by technology

[0004] The above-mentioned eccentric sleeve adjustment device for wedge-type hot die forging presses has the following disadvantages: A. During the process of aligning the inner hexagon nut with the outer hexagon nut, since the inner hexagon nut cannot be seen, the operation is very difficult and requires experienced professionals Only a fitter can complete it; B. The adjustment time is long, which affects production efficiency; C. The rigidity and precision of the adjustment trolley are very high, otherwise it will affect the alignment of the inner and outer hex nuts; D. The adjustment trolley takes up a lot of space and is far from the ground. The height is too low, which affects the automatic connection of the equipment; E. There are many pipelines for adjusting the trolley, and the failure rate is high

[0005] CN203484597U discloses a locking mechanism for the eccentric sleeve of a hot die forging press, which only improves the loosening and clamping mechanism of the eccentric sleeve, although the original structure reduces the volume of the equipment to a certain extent , but its locking driving device is fixedly connected to one of the ends of the open end of the ring connecting rod, which is called the force end, and the other end of the opening end of the ring connecting rod is called the force end, and the locking driving device Located on the outer surface of the force end of the open end, it not only occupies the space under the big head of the connecting rod, but also requires high machining accuracy, and the force on the two ends of the open end of the ring connecting rod is uneven, and the deformation of the force end of the opening is larger than that of the force end of the opening. Large amount of deformation
