Description
Technical field
This utility model relates to Stamping Die Technology field, specifically a kind of high-strength bolt stock flush end decompressor.
Background technology
As in figure 2 it is shown, common bolt stock blanking die, all producing the phenomenon that end face is uneven, especially when the product that blanking intensity is relatively low, this phenomenon is more serious.Reason is as the punching press of cutter, stock can run-off the straight gradually, the section of stock gradually changes and no longer smooth.The generation of this phenomenon not only wastes raw material, further increases step (needing polishing) and the production cost of production technology.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiency in above-mentioned background technology, it is provided that a kind of high-strength bolt stock flush end decompressor, it is possible to the section keeping stock is smooth, and has easy to use, the feature of simple in construction.
The technical solution adopted in the utility model is as follows: a kind of high-strength bolt stock flush end decompressor, it is characterised in that: include the knife plate being arranged on punch press, the blanking punched mould of flush end being arranged on substrate and resilient abutment mechanism；The lower end of knife plate is shaped with semicircle nock; the blanking punched mould of flush end includes tool rest, protection block and spring part; tool rest is fixed on substrate; protection block is liftably arranged on the stock hole exits place of tool rest; protection block top be shaped with knife plate in opposite directions and to semicircle nock; spring part is fixed on base plate bottom, and the push rod bottom protection block is resisted against spring part top after the through hole of substrate；Resilient abutment mechanism includes pedestal, tommy bar and spring lever, pedestal is fixed on substrate, tommy bar is coaxially arranged with stock hole and passes through hinge on pedestal, the top of pedestal is respectively equipped with adjusting screw rod and the first spring, adjusting screw rod downwardly extends and is resisted against on the tommy bar on rear side of bearing pin, first spring downwardly extends and is resisted against on the tommy bar on front side of bearing pin, is arranged in the elongated hole of tommy bar front end after sheathed second spring of spring lever.
As preferably, the semicircle nock of described knife plate lower end forms a manhole after closing up with the semicircle nock protecting block top, and the radius of this manhole is identical with the radius in described stock hole.
As preferably, the middle part of described pedestal offers elongated slot, and tommy bar is hinged in this elongated slot.
As preferably, described spring part is rubber spring.
As preferably, the substrate between the blanking punched mould of described flush end and resilient abutment mechanism offering blanking port.
The beneficial effects of the utility model are: this utility model is provided with a protection block being resisted against on spring part on tool rest; when punching press; this protection block is close together motion with knife plate all the time; thus realizing the clamping of stock and location, it is to avoid stock is subject to that gravity factor is downward-sloping and that cause section is uneven；Simultaneously, the spring lever in resilient abutment mechanism is utilized to realize axial flexibly positioned of stock, and tommy bar can swing up and down along with punching press action, offsetting the gravity impact that stock is subject to, thus ensureing that stock is indeformable, overall structure is simple, easy to use, the polishing time can be reduced, improve production efficiency, reduce production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of existing decompressor.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail, but this utility model is not limited to following example.
As it is shown in figure 1, a kind of high-strength bolt stock flush end decompressor that this utility model provides, including the knife plate 5 being arranged on punch press, the blanking punched mould of flush end on substrate 1 and resilient abutment mechanism are installed.Substrate between the blanking punched mould of described flush end and resilient abutment mechanism offers blanking port 12.
The lower end of described knife plate is shaped with semicircle nock 6; the blanking punched mould of flush end includes tool rest 2, protection block 7 and spring part 9; tool rest is fixed on substrate; protection block is liftably arranged on the exit, stock hole 3 of tool rest; knife plate againsts stock hole exits place and arranges; protection block top be shaped with knife plate in opposite directions and to semicircle nock 4; the top and bottom of spring part are provided with packing ring 10; fixing bolt 11 is fixed on base plate bottom after backing plate and spring part, and the push rod 8 bottom protection block is resisted against spring part top after the through hole of substrate.Described spring part is rubber spring, and when the downward punching press of knife plate, protection block stress is offset the elastic force of rubber spring and moved downward, when knife plate rises, and rubber spring return, will protection block jack-up.The semicircle nock of described knife plate lower end forms a manhole after closing up with the semicircle nock protecting block top, and the radius of this manhole is identical with the radius in described stock hole.
Described resilient abutment mechanism includes pedestal 13, tommy bar 21 and spring lever 20.Pedestal is fixed on substrate, the middle part of pedestal offers elongated slot 14, tommy bar is coaxially arranged with stock hole and is hinged in the elongated slot of pedestal by bearing pin 16, the top of pedestal is respectively equipped with adjusting screw rod 15 and the first spring 18, adjusting screw rod downwardly extends and is resisted against on the tommy bar on rear side of bearing pin thus limiting the amplitude that tommy bar rotates down, first spring compresses and is resisted against on the tommy bar on front side of bearing pin by nut 17, thus limiting the amplitude that tommy bar is rotated up, being arranged in the elongated hole of tommy bar front end after sheathed second spring 19 of spring lever, the front end of spring lever is provided with disk.
Usually, stock stock B inserts from stock hole 3, and end abuts on spring lever so that the second spring-compressed；The downward punching press of knife plate afterwards, protection block and the edge of a knife move downwardly together, are cut off by stock A from stock stock, and in this process, tommy bar can be pulled in the end of stock, it is to avoid rigid contact and deform；Stock drops from blanking port after completely cutting through, and knife plate, protection block, spring lever and tommy bar reset.
The foregoing is only preferred embodiment of the present utility model, for a person skilled in the art, this utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
