Description

A kind of hand blanking die

Technical field

The utility model relates to a kind of mould structure, particularly relate to a kind of easy, mould structure manually.

Background technology

Present thin plate (thickness 0.3-0.5mm) is when the mould stamping-out, and mode commonly used is drift to be installed in carry out press work on the forcing press.When on press machine, carrying out press work certain danger is arranged, and press machine is relatively more expensive, complex operation.Enterprise will consider employee's safety when producing, avoid having an accident.And will spend more fund and be used for buying press machine, the operation pressing equipment also need consume a large amount of electric energy.Employ stamping machine for this type of thin plate of processing; Employing seems low load with strong power with upper type; Excessive use machinery is arranged, consume the suspicion of the energy excessively, for fear of the generation security incident of member when the worker operates; And reducing the required cost of enterprise's purchase of equipment, hope can provide a kind of simple thin plate blanking die of operation manually.Price is more cheap than stamping machine bed, operates safer.

Summary of the invention

The utility model is intended provides a kind of ability the suitable simple thin plate blanking die structure of operation manually, reaching the generation security incident of the person of avoiding when the operation, and minimizing enterprise purchase of equipment, and the purpose of the required cost of consumes energy in the production process.

The purpose of the utility model is achieved by following technical scheme:

A kind of hand blanking die comprises part of the upper die and part of the lower die, it is characterized in that:

Said part of the upper die: on train wheel bridge, offer the punch hole, in the punch hole, embed punch, punch is connected on the punch retainer of top by soket head cap screw, punch retainer is fixed on the upper surface of train wheel bridge again by soket head cap screw;

Said part of the lower die: on backing plate, offer shoulder hole, in shoulder hole, dispose the die of bead outside the circle, soket head cap screw is the fixing outer bead of die from the bottom of backing plate;

Pair of supporting is fixed on a side of backing plate by soket head cap screw, between two bracing frames optical axis is set, and through the be rotationally connected train wheel bridge of part of the upper die of optical axis, the rightabout side of train wheel bridge and optical axis is provided with handle.

Further, two spring symmetries are installed on the backing plate; Die is positioned on the backing plate through straight pin, and backing plate cooperates with the dowel hole that the top train wheel bridge is offered through the fixing alignment pin of interference fit.

Further, on said backing plate, pin stop is set.

Further, locate through straight pin and train wheel bridge at said punch retainer.

Further, be mounted on the train wheel bridge through engage thread at said handle.

There is following problem in the thin plate blanking die at present: one, blanking die carries out work on press machine, and danger is bigger when punching press, to employee's person formation harm; Two, carrying out press work just needs to buy corresponding press machine, and the pressing equipment price is expensive.For this reason, the utility model has designed a kind of blanking die of cutting knife type, and punch is installed on train wheel bridge, and die is installed on backing plate.Through depressing handle punch is moved downward, cooperate the stamping-out workpiece with die on being installed in backing plate.According to the size of required blanking pressure, confirm the brachium of handle.

The advantage of the utility model, the apparatus structure of employing the utility model, the simple and easy blanking die of cutting knife type can manual work carry out work, need not on press machine, to carry out work.Contingent security incident when this had both been avoided on press machine, carrying out work has deducted enterprise again and has bought required cost on the press machine.In a word, the simple and easy blanking die design of this cutting knife type provides a kind of novel and practical blanking equipment.The simple and easy blanking die of cutting knife type that uses this paper to propose, economic benefit is with considerable.And stamping-out is one of basic working procedure of Sheet Metal Forming Technology, in punch process, uses extremely extensively, and very big prospect and the value applied are arranged.
