Hydraulic stop block mechanism of powder forming machine

Abstract

The invention provides a hydraulic stop block mechanism of a powder forming machine. The hydraulic stop block mechanism comprises a cross arm and two ejecting rods matched with the cross arm, wherein two cross arm resetting air / oil cylinders are mounted on a frame; a lower spindle connected with a T-shaped block is fixed on the cross arm; and the cross arm is matched with the oil cylinders mounted on the frame through the lower spindle and can move up and down. The number of original parts and the processing volume are large, and the original parts are irregular parts which are difficult to process and mount, are easy to wear and need to be frequently maintained and replaced. By adopting the hydraulic stop block mechanism, the original components are replaced only by using the height-adjustable oil cylinders mounted on the frame, and two original transmission rods, namely a pressure rod and a demoulding rod are replaced by using the ejecting rods, parts need not to be processed, the oil cylinders are simple and convenient to maintain and replace, time and labor are saved, and the production cost is greatly reduced; meanwhile, the sizes of the oil cylinders are configured according to needs, the positions of pistons in the oil cylinders can be regulated in height, and the pistons are used for processing different parts, so that the structure can be mounted and used on powder forming machines of different tonnages and different types, the generality is high, the practicality is high, the use effect is good and processing quality of products is guaranteed.

Description

technical field [0001] The invention relates to an important part of a powder forming machine, which enables the powder forming machine to continuously operate the automatic block demoulding, and a powder forming machine hydraulic stop mechanism to ensure the processing quality of pressed products. Background technique [0002] Chinese Patent No. 01245708.6 "Demolition Device for Powder Molding Machine" has a complex structure. The pressure wheel on the swing arm cooperates with the pressure block on the cross arm, and a boom with bearings, rollers, and roller shafts needs to be processed on the swing arm. , so its volume is large, and it is difficult to process many parts. It is only suitable for installation and use on small-tonnage powder forming machines.

[0002] Chinese Patent No. 01245708.6 "Demolition Device for Powder Molding Machine" has a complex structure. The pressure wheel on the swing arm cooperates with the pressure block on the cross arm, and a boom with bearings, rollers, and roller shafts needs to be processed on the swing arm. , so its volume is large, and it is difficult to process many parts. It is only suitable for installation and use on small-tonnage powder forming machines.

[0003] Chinese Patent No. 200520131909.7 "Powder Molding Machine Female Mold Release Block Mechanism" replaces the original cross arm plus swing arm with an independent cross arm, cancels the swing arm and adopts the stop mechanism, but the cross arm still needs to be connected with the pressure rod , Ejection rod, and stopper mechanism, the stopper mechanism is an irregular part, it is difficult to process and install, and it is easy to wear after a long working time, and it is very troublesome to replace and maintain

[0004] Chinese Patent No. 200610053095.9 "Female Block Mechanism of Powder Forming Machine" uses a simple and easy-to-process inclined block to directly cooperate with the ejection rod, and drives the entire slider to move outward through the roller at the lower end, so that the pad on the bottom of the slider Break away from the contact with the stopper, so that the female template can move downward to complete the floating demoulding of the female mold. Although the structure has been improved, its structure is still relatively complicated, and there are many parts to be processed, and it is also difficult to process and install.
