Description

one
The invention relates to a hydraulic drive of a woodworking machine and can be used in the forest and woodworking industry.
Known hydraulic mechanism of the clamping trolley band saw machine, comprising a hydraulic cylinder, distributors and pipelines.
However, the known hydraulic drive has a complex control system and low reliability,
The aim of the invention is to simplify the design and increase the reliability of the hydraulic drive. To do this, the supply lines for the piston and rod cavities of the hydraulic cylinder are installed with normally closed and normally open controlled valves, and the normally open valve is interconnected by means of a pressure switch with the piston cavity of the hydraulic cylinder.
The drawing shows a diagram of the proposed hydraulic drive.
It contains a hydraulic cylinder 3 connected to the upper 1 and lower 2 clamping hooks. A normally closed valve 5 is connected to the pipe 4 of the piston cavity of the piston cavity, and a normally open valve 7 in the pipe supply pipe of the rod of the cylinder.
control, and the electromagnet Em2 of the distributor 7 can be activated by means of a pressure switch 8.
The hydraulic actuator works as follows.
When the electromagnets EM1 and EM2 are turned off, the oil enters the rod end of the hydraulic cylinder 3 through the distributor 7, and its piston cavity through the distributor 5 is connected to the drain. Hooks 1 and 2 are separated.
When the electromagnet Em1 of the distributor 5 is turned on, its spool switches and connects the piston cavity of the hydraulic cylinder 3 to the pressure line. The hydraulic cylinder is activated in a differential circuit, and the hooks 1 and 2 converge and interact with the log 9. The pressure in the piston cavity of the hydraulic cylinder 3 rises and the pressure switch 8 issues a command to turn on the electromagnet Em2 of the distributor 7. The valve spool switches, and the rod cavity of the hydraulic cylinder 3 connects It comes with a drain. The log is clamped with the necessary force.
To unseat the logs, the power supply circuits of the electromagnets Em1 and Em2 of the distributors 5 and 7 are turned off. The spools of the distributors are installed in springs (as shown in the drawing), the oil enters the rod end of the hydraulic cylinder 3 through the distributor 7, and the piston cavity of the hydraulic cylinder through the distributor 5 is connected to the drain. The hydraulic cylinder rod retracts and retracts the clamping hooks 1 and 2 from the log 9.
Subject invention
The hydraulic drive of the clamping mechanism of the band saw machine, including a hydraulic cylinder, distributors and pipelines, is characterized in that, to increase reliability of operation, the normally closed and normally open controlled distributors are installed on the supply pipelines of the piston and rod cylinder cavities, respectively, the latter being connected by means of pressure switch with piston cylinder cavity.
