Description
Technical field
The utility model belongs to mold and punching head technical field, specifically, and particularly a kind of Separated type combination drift.
Background technology
At present, car beam like members cutting die generally needs to use multipart punch, this multipart punch comprises backing plate, fixed head and two little drifts, wherein the middle part of fixed head upwards extends to form a special-shaped plunger chip, and this special-shaped plunger chip left part is rectangular section, and right part is major part section, two little drifts are provided with in the both sides, front and back of special-shaped plunger chip rectangular section of right-hand member, described little drift is from bottom to top through fixed head, and have backing plate at fixed head, lower end and the backing plate of described little drift offset.In using, described fixed head and backing plate are fixed on die holder by bolt and alignment pin.When assembling and setting, because special-shaped plunger chip and fixed head are one, once mobile special-shaped plunger chip, described fixed head also moves together, the pin-and-hole of alignment pin and little drift also and then together with move, make the assembling and setting of each drift very inconvenient.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Separated type combination drift being convenient to assembling and setting.
The technical solution of the utility model is as follows: a kind of Separated type combination drift, comprise backing plate, fixed head and little drift, wherein fixed head is cut narrow rectangular block gradually by left part and is formed, also chamfering has been cut at the right-hand member of fixed head, both sides, front and back in the middle part of fixed head all have installing hole, little drift is inserted with from bottom to top in described installing hole, backing plate is provided with in the below of described fixed head, lower end and the backing plate of described little drift offset, described fixed head has profiled holes, the left part of described profiled holes is rectangular section of left and right directions, and this right-hand member of rectangular section is between former and later two little drifts, the both sides, front and back of described profiled holes right part are outwards widened, form the major part section that two ends, left and right are narrowed, the special-shaped plunger chip of column is fitted with in described profiled holes, the lower end of described special-shaped plunger chip and profiled holes matched in clearance, the top of special-shaped plunger chip is exposed outside fixed head, and the extension pin of fore-and-aft direction is inserted with in the left part lower end of described fixed head, the described bottom hanging pin and run through special-shaped plunger chip, screw is inserted with from bottom to top at the right part of described backing plate, the upper end of this screw is inserted in special-shaped plunger chip.
Adopt said structure, profiled holes left by fixed head, in profiled holes, special-shaped plunger chip is installed, thus special-shaped plunger chip is set separately, make to carry out installation and debugging respectively between special-shaped plunger chip and fixed head and little drift, the debugging avoiding special-shaped plunger chip affects the position of fixed head and little drift, makes the assembling and setting of each drift more convenient.And the left part of special-shaped plunger chip is connected with fixed head by hanging pin, and the right part of special-shaped plunger chip is fixed by screw and backing plate, not only make the installation of special-shaped plunger chip, dismounting and debugging convenient, and special-shaped plunger chip and being connected firmly between fixed head and backing plate, to stablize.
The two ends, left and right of described special-shaped plunger chip lower end all have breach of stepping down, and this breach of stepping down is stuck on the end face at two ends, fixed head left and right.Generally for the intensity meeting fixed head, fixed head needs to be formed special-shaped plunger chip lower end to enclose, and makes that the outer rim of fixed head does not have breach, so just requires that the outer rim of fixed head all stretches out the outer rim of special-shaped plunger chip, and the size of such fixed head is inevitable larger.And the utility model by arranging breach of stepping down on special-shaped plunger chip, effectively control the size of fixed head, make overall structure compacter, production cost is lower.
Described fixed head has four via holes, these four via holes lay respectively at front and the back at two ends, fixed head left and right, have former and later two pin-and-holes at the middle part of described fixed head, described pin-and-hole is positioned at the right of corresponding installing hole, and described backing plate has the hole relative with via hole and pin-and-hole.Such fixed head and backing plate are fixed on die holder by the screw running through four via holes, then by inserting pin-and-hole and the alignment pin stretching into die holder is accurately located, and make overall easy for installation, accurate, firm.
Beneficial effect: the utility model by opening profiled holes on fixed head, in profiled holes, special-shaped plunger chip is installed, thus special-shaped plunger chip is set separately, make special-shaped plunger chip and fixed head and little drift can carry out installation and debugging respectively, the debugging avoiding special-shaped plunger chip affects the position of fixed head and little drift, make the assembling and setting of each drift more convenient, have be skillfully constructed, structure is simple, transformation easily and the feature such as improvement cost is low.
