Abstract
The invention relates to a mould and a working method of the mould, and belongs to the technical field of metal stamping. The punching mould comprises an upper mould base, a lower mould base, a male mould body, a female mould body, vertical guide columns and square guide sleeves. A female mould hole is formed in the female mould body, and wing plate side faces of the vertical guide columns are in sliding fit with a pair of opposite inner side faces of the square guide sleeves; brakes connected with external brake pipelines are arranged at the lower ends of the vertical stand columns; and each brake comprises a pair of oppositely-arranged brake shoes with one end hinged to a web plate of the corresponding vertical guide column, and the other ends of the pair of brake shoes are in rolling connection with a driving cam; and an inclined face and a friction piece which is arranged on the inclined face are arranged on each brake shoe, and the inclined face inclines towards the other end of the brake shoe. When the square guide sleeves are located at the brakes at the lower ends of the vertical guide columns, the driving cams drive the brake shoes to rotate and enable the friction pieces to be attached to the other pair of opposite inner side faces of the square guide sleeves in a clamped manner. The punching mould has the advantage that under the dangerous condition, a micro punching machine is emergently braked, and therefore safety of personnel is protected.
Description
The application is divisional application, the invention and created name of original application: the blanking die with braking function, application number: 201310266209.8, the applying date: 2013-06-28.
Technical field
The present invention relates to a kind of mould, belong to metal stamping techniques field.
Background technology
Punch press process in machining occupies an important position in the processing industry of national economy.The application of sheet metal component is extremely extensive, and be deep into manufacturing various aspects, sheet material forming realizes mainly through blanking die.Adopt punching process, have that precision is high, efficiency is high, quality is good, cost-saving, save the series of advantages such as material and the energy.
At present, a lot of enterprise, when utilizing blanking method processing, still continues to use simple handwork method, namely directly get part die cavity is in-built with hand, and a large amount of blanking equipments is all responsible for the manufacturing operation of multiple product or working procedures.In this case, if blanking equipment and mould do not have security protection to fill very easily hinder the accidents such as hand.So, in stamping-out is produced, strengthen security protection, safety is administered and progressive mechanization degree, is the vital task that Accident prevention occurs.
Blanking equipment is very large on safety in production impact.As punch press inherently defectiveness, lack safety device, clutch, brake are reliably sensitive not, and electrical equipment control structure is suddenly out of control and occur even to rush phenomenon, and accessory tool defectiveness etc., are all the major reasons caused the accident.
Applicant finds, the accident occurrence frequency of miniature or small-sized clicker press machine is high, therefore, carries out Safe Transformation trial to miniature or small-sized clicker press machine, is to reduce the key of hindering the accidents such as hand.
