Plane cutting machine with safety posts

Abstract

The invention discloses a plane cutting machine with safety posts. The plane cutting machine with the safety posts comprises a main body and a downward pressing plate. A working table is arranged on the upper part of the main body; a hydraulic cylinder, a transmission device and other power mechanisms are arranged in the main body; the downward pressing plate and the main body are connected through four stand columns; a control panel is further arranged on the main body; a starting switch and an emergency stop switch are arranged on the downward pressing plate; a base and a hydraulic lifting column are further arranged in the main body; the hydraulic lifting column is vertically placed on the base; a hole for the hydraulic lifting column to penetrate through is formed in the working table;and the hydraulic lifting column is provided with a starting switch. When an accident happens, the emergency stop switch is pressed down, the working table of the cutting machine lifts up the hydraulic lifting column to support the downward pressing plate and push the downward pressing plate to lift again; and when the machine is stopped and overhauled, the lifting hydraulic cylinder can be further controlled to lift to support the downward pressing plate, so that the accident caused by the falling of the downward pressing plate due to depressurization of the hydraulic cylinder after machinestop is prevented.

Description

technical field [0001] The invention belongs to the technical field of plane cutting machine equipment, in particular to a plane cutting machine with a safety column. Background technique [0002] Plane cutting machine is an indispensable equipment in some light industries. It is a machine that uses the force of machine movement to pressurize the die to punch non-metallic materials. When the plane cutting machine is working, it is strictly forbidden for the operator to put his hands on the work surface to prevent the lower pressing plate from pressing the operator’s hand. In case of accident, the lower pressing plate of the cutting machine can be stopped by the emergency stop switch, and the lower pressing plate can be turned down by the return button. Pressing plate return, some cutting machines set the return button and the emergency stop switch button as the same button, which can immediately control the return of the lower pressing plate in the event of an accident.

Problems solved by technology

When the plane cutting machine is working, it is strictly forbidden for the operator to put his hands on the work surface to prevent the lower pressing plate from pressing the operator’s hand. In case of accident, the lower pressing plate of the cutting machine can be stopped by the emergency stop switch, and the lower pressing plate can be turned down by the return button. Pressing plate return, some cutting machines set the return button and the emergency stop switch button as the same button, which can immediately control the return of the lower pressing plate in the event of an accident. However, because this method is to turn the internal steering valve of the cutting machine, and then control The movement of the hydraulic cylinder makes the lower pressure plate return to its position. In actual production, the pressure of the hydraulic cylinder is often released after an emergency stop, and the power is lost, so the lower pressure plate cannot be raised.

[0003] When the cutting machine is shut down for maintenance, it is often necessary to place hard objects such as wooden blocks between the lower platen and the work surface to support the lower platen to prevent accidents caused by the sudden release of pressure from the hydraulic cylinder after the machine is shut down, but the additional hard objects such as wooden blocks The support is not stable enough, it is easy to skew and lose the support effect
