An anti-drop mechanism for a slide block of a hydraulic press

Abstract

The invention discloses an anti-falling mechanism for a sliding block of a hydraulic machine. The anti-falling mechanism for the sliding block of the hydraulic machine comprises a gear rack; a gear rack fixing seat is arranged on the front surface of the upper end of the gear rack; a spring baffle plate is fixedly mounted at the bottom of the gear rack fixing seat through a bolt; the lower end of a gear buckle supporting seat extends out of the spring baffle plate; a spring is arranged at the lower part of the gear buckle supporting seat in a sleeving manner; the spring is positioned above the spring baffle plate; a screw nut is mounted at the lower end of the gear buckle supporting seat; an emergency stop switch is arranged under the screw nut; a sporting plate is arranged above the gear buckle supporting seat and is fixedly connected with the gear buckle supporting seat; the top end of the gear buckle supporting seat is hinged with a gear buckle through a pin; the left end of the gear buckle is hinged with a connecting block; an air cylinder is mounted at the left end of the supporting plate; a connecting screw is arranged at the right part of a piston rod of the air cylinder; another spring is arranged on the connecting screw in a sleeving manner; a top pillar is arranged on the right side of the connecting screw. The anti-falling mechanism for the sliding block of the hydraulic machine can effectively prevent the sliding block of the hydraulic machine from travelling downward abnormally, has a real-time protective effect on abnormal downward travelling of the sliding block of the hydraulic machine, stops a potential safety hazard, and is suitable to be applied to production equipment for various pressing structures.

Description

technical field [0001] The invention relates to the technical field of hydraulic presses, in particular to a hydraulic press slide block anti-falling mechanism. Background technique [0002] In the automobile and spare parts manufacturing industry, stamping is the main processing procedure. Although the degree of automation in the current industry has been greatly improved compared to the past, most of the stamping machines are still manually operated. Although today's stamping equipment has safety protection devices, there are still many potential safety hazards. Therefore, various stamping accidents occur from time to time, causing many Lots of tragedies. Photoelectric protection is used in the industry to prevent the dangers caused by various human misoperations, but it does not have the protective effect on the dangers caused by the failure of the machine itself. Sliding and falling, hydraulic machine clutch failure may also lead to secondary continuous punching. Becau...

Problems solved by technology

[0005] This type of anti-drop mechanism can eliminate the danger of the slide block falling when the hydraulic press is shut down for maintenance, but it cannot be used when the hydraulic press is performing stamping operations, so it cannot prevent the hidden danger of the slide block suddenly falling during the operation of the hydraulic press
