There is diel and the method for work thereof of safety protection function
the application is divisional application, the invention and created name of original application: the diel with safety protection function, application number: 201310266387.0, 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 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 diel.Adopt Sheet Metal Forming Technology, 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 process for stamping processing, still continues to use simple handwork method, namely directly get part die cavity is in-built with hand, and a large amount of pressing equipments is all responsible for the manufacturing operation of multiple product or working procedures.In this case, if pressing equipment and mould do not have security protection to fill very easily hinder the accidents such as hand.So, in punching production, strengthen security protection, safety is administered and progressive mechanization degree, is the vital task that Accident prevention occurs.
Pressing 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, accident occurrence frequency that is miniature or small-sized punching machine is high, therefore, carries out Safe Transformation trial to miniature or small-sized punching machine, is to reduce the key of hindering the accidents such as hand.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, propose a kind of can the diel with safety protection function of brake hard and method of work thereof.
The present invention is the technical scheme solving the problems of the technologies described above proposition: a kind of diel with safety protection function, comprise the upper bolster and die shoe that are oppositely arranged, described upper bolster is provided with punch, described die shoe is provided with die, described die is shaped with the die groove coordinated with punch, described die is provided with the pressing plate for striking out shaped piece flanging, described die shoe is fixed with I-shaped vertical guide pillar, described upper bolster is provided with and the square guide pin bushing that is slidably matched on vertical guide pillar, the pair of inside face that the wing plate side of described vertical guide pillar is relative with square guide pin bushing is slidably matched, the web of described vertical guide pillar lower end is provided with the lining brake connecting outer brake pipeline, when described square guide pin bushing is positioned at the lining brake place of vertical guide pillar lower end, described lining brake stretches out another inner surface sides relative with square guide pin bushing and fits and locking.Described punch is provided with the checkout gear for detecting foreign matter in punch undershoot stroke, and the output of described checkout gear is connected with the input of control device, and the output of described control device connects the control end of brake piping; Checkout gear is infrared detecting device.Described vertical guide pillar is at least two vertical guide pillars arranged in parallel, each vertical guide pillar is provided with a square guide pin bushing.
The method of work of described diel, it comprises: when described square guide pin bushing is positioned at the lining brake place of vertical guide pillar lower end, and described lining brake stretches out another inner surface sides relative with square guide pin bushing and fits and locking.
The present invention adopts the beneficial effect of technique scheme to be: be provided with the lining brake connecting outer brake pipeline by the web of vertical guide pillar lower end; when square guide pin bushing is positioned at the lining brake place of vertical guide pillar lower end; lining brake stretches out another inner surface sides relative with square guide pin bushing and fits and locking; on minitype stamping machines; when occurring on dangerous situation; can brake hard be realized, protect the safety of personnel.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is the structural representation that the embodiment of the present invention has the diel of safety protection function.
Detailed description of the invention
Embodiment
The diel with safety protection function of the present embodiment, as shown in Figure 1, comprise the upper bolster 1 and die shoe 2 that are oppositely arranged, upper bolster 1 is provided with punch 3, and die shoe 2 is provided with die 4, die 4 is shaped with the die groove coordinated with punch 3.Die 4 is provided with the pressing plate 11 for striking out shaped piece flanging.
Die shoe 2 is fixed with I-shaped vertical guide pillar 5, upper bolster 1 is provided with and the square guide pin bushing 6 that is slidably matched on vertical guide pillar 5.
The pair of inside face that the wing plate 5-1 side of vertical guide pillar 5 is relative with square guide pin bushing 6 is slidably matched, and the web 5-2 of vertical guide pillar 5 lower end is provided with the lining brake 8 connecting outer brake pipeline 7.When square guide pin bushing 6 is positioned at lining brake 8 place of vertical guide pillar 5 lower end, lining brake 8 stretches out another inner surface sides relative with square guide pin bushing 6 and fits and locking.
The punch 3 of the present embodiment is provided with the checkout gear 9 for detecting foreign matter in punch undershoot stroke, and the output of checkout gear 9 is connected with the input of control device 10, and the output of control device 10 connects the control end of brake piping 7.Checkout gear 9 can be electromagnetic detection, also can be infrared detecting device.
The vertical guide pillar 5 of the present embodiment is at least two vertical guide pillars arranged in parallel, and each vertical guide pillar 5 is provided with a square guide pin bushing.
The present invention is not limited to above-described embodiment.All employings are equal to the technical scheme of replacing and being formed, and all drop on the protection domain of application claims.
