AI Technical Summary

Technical Problem

Existing stamping molds are prone to finger clamping during operation. Existing protective measures such as pressing buttons with both hands and electronic protection have problems such as high labor intensity, easy failure and visual detection lag, making it difficult to effectively prevent hand clamping.

Method used

A stamping mold tool for anti-pinching hands is designed, adopting dual measures of mechanical protection and electronic protection. Infrared detection is performed through the infrared fence. When the finger is in a dangerous area, the alarm light is triggered and the hydraulic cylinder is controlled to stop the stamping; at the same time, the hydraulic cylinder drives the gear and rack to mesh, driving the swinging rod and protective plate to swing, swaying the fingers to prevent clamping the hand.

Benefits of technology

It effectively prevents finger clamping of operators, improves operating safety through double protection measures, and avoids the risk of clamping hands caused by electronic protection failure or visual detection lag.

Description

Technical Field

[0001] The utility model relates to the technical field of stamping devices, in particular to a stamping die tooling for preventing fingers from being pinched. Background Art

[0002] Stamping dies are a type of large-scale metal cutting equipment widely used in the automotive, home appliance, electronics and other industries. They are mainly used to convert metal sheets or pipes into products of the required shape, size and tolerance after a certain process.

[0003] Stamping dies are generally composed of multiple parts, including templates, guide devices, cooling systems, hydraulic systems, etc. Among them, the template is the core part of the stamping die, and its design and manufacturing directly affect the quality and efficiency of the product. Common types of stamping dies include single-process, multi-process, composite materials and other types of stamping dies.

[0004] Manual loading of stamping molds requires manual placement of the product to be stamped on the stamping mold table. The guide system drives the upper and lower molds to press and stamp. If the operator does not operate in a standardized manner, his fingers will be placed between the upper and lower molds, which may easily cause injury to the fingers during stamping. Currently, existing companies have two ways to prevent finger pinching: one is to set up a two-handed button stamping method to prevent finger pinching. Two-handed pressing and stamping requires high labor intensity; the other is to set up electronic protection for protection. Electronic protection is prone to malfunction. Visual inspection relies on software calculations. Once the computer crashes or lags, finger pinching may occur. Utility Model Content

The rack 32 drives the gear 31 to rotate and further drives the swing rod 33 and the protective plate 34 to swing, thereby swinging the staff's fingers out to prevent hand crushing.

[0034] The utility model workflow:

[0035] During use, infrared detection is performed through the infrared fence 41. When the punching personnel's fingers are in the dangerous area, the infrared fence 41 triggers the alarm light 42 to sound an alarm, and the controller controls the hydraulic cylinder 22 to stop punching. When the controller starts the hydraulic cylinder 22 for punching, the hydraulic cylinder 22 drives the upper module 23 to move downward, driving the gear 31 to move downward. The gear 31 is meshed and connected with the rack 32. The rack 32 drives the gear 31 to rotate, further driving the swing rod 33 and the protective plate 34 to swing, so as to swing the staff's fingers out to prevent hand crushing.
