Abstract
The invention discloses a method for manufacturing spring washers. A spring washer blanking die and a thick plate feeding machine are adopted in the method, wherein the spring washer blanking die is connected with a punching machine; coil stock is used as raw materials. The method comprises the steps that 1, the coil stock is fed to the upper surface of an upper die of the spring washer blanking die through the thick plate feeding machine; 2, the punching machine drives the upper die to move downwards to conduct stamping on the coil stock at a time, and at least three spring washers are obtained; 3, the upper die moves upwards to be separated from a lower die; 4, the steps 1-3 are executed again, and the spring washers are obtained repeatedly. According to the method for manufacturing the spring washers, the operation process is simple, and the raw materials are saved.
Description
Technical field
The present invention relates to parts and make that the washer preparation method, particularly a kind of operating process in field is simple, the preparation method of the washer that economizes in raw materials.
Background technology
Blanking die, comprises upper die and lower die, and patrix connects punching mechanism, by punching mechanism, makes patrix press to counterdie matched moulds, is positioned at the workpiece that raw material on counterdie is stamped into patrix shape.
In traditional washer production process, first user needs coiled strip to be cut into the bonding jumper of strip, and then send into and in washer blanking die, carry out punching press, production process technology is complicated, need to expend a large amount of bonding jumpers of manually preparing strip, for production in enormous quantities, traditional washer preparation method production efficiency is extremely low, in addition, prepare in the process of bonding jumper of strip and can produce a large amount of leftover pieces, waste raw material.
Summary of the invention
The invention provides that a kind of operating process is simple, the preparation method of the washer that economizes in raw materials.
Technical scheme provided by the invention is: a kind of preparation method of washer, the equipment utilizing comprises washer blanking die and the slab feeder being connected with stamping machine, raw material is coiled strip, described washer blanking die, comprise upper die and lower die, the lower surface of described patrix is provided with several washer punch, the upper surface of described counterdie is provided with and the above-mentioned washer punch recess of corresponding matching one by one, it is characterized in that, the quantity of described recess is at least 4 and all recesses and is arranged at least two row, and the recess in two adjacent row is staggered front to back distribution; The center of each described recess equates to the distance R at the center of adjacent recess; The preparation method of described washer comprises the following steps:
Step 1: by described slab feeder, described coiled strip is delivered to the counterdie upper surface of washer blanking die;
Step 2: drive by stamping machine that patrix is descending carries out a punching press to coiled strip, obtain at least 4 washers;
Step 3: described patrix is up, separated with counterdie;
Step 4: repeating step 1～step 3 can obtain washer repeatedly.
In the preparation method of above-mentioned washer, the cross section of described recess is circular, and the radius of described circle is r; Described distance R is 2.5～6 times of radius r.
In the preparation method of above-mentioned washer, described step 2 also comprises the part of punching press on coiled strip and just in the part of punching press, is carrying out cutting and separating.
In the preparation method of above-mentioned washer, described washer blanking die is also provided with and stops into inductor and retaining inductor, and described stopping into inductor goes downwards to after descending predeterminated position for sensing patrix, sends only inlet signal and to stamping machine, stops descending; Described retaining inductor is used for sensing that patrix is up to after up predeterminated position, sends retaining signal and to stamping machine, stops uply, and sends feed signal simultaneously and to slab feeder, carries out the operation of described step 1.
Compared with prior art, washer blanking die of the present invention on upper die and lower die, arrange respectively a plurality of washer punch and for recess, particularly adopt the mode a plurality of washers of punching simultaneously in one plane be equidistantly staggered front to back distribution, the distribution mode at this punching press position can guarantee that coiled strip is when punching press, each pressurized position pressurized is balanced, prevents from causing the inconsistent problem of washer finished form because of unbalance stress; And this programme adopts the mode of coiled strip charging, removes tradition from and prepares the operation that washer must be cut into long-bar metal shape, and it is more convenient to operate, avoided the waste of the leftover pieces that occur in this process simultaneously.Than traditional single head washer blanking die, in this method, distance R is radius r 2.5～6 times time, can save 10-20% raw material-coiled strip.
Further, what adopt due to the raw material of this aspect is coiled strip, so slab feeder can be used in conjunction with this washer blanking die, realizes self-feeding, and excises waste material by cutting knife, and handled easily personnel collect waste material.
