Abstract
Self-discharging pilot pin, including the cylindrical pilot pin pin with conehead, improvements introduced be：There are ring convex in the middle part of pin, there are several ejector pin pilot holes in ring convex, there is ejector pin in ejector pin pilot hole, there is compression spring in the ring convex above section of pin, fixed cover is installed outside spring, passing the pin end at bottom on fixed cover has the collar being locked in fixed cover on pin, fluted on ring convex cylinder or shoulder, pilot pin press-in is assembled on upper molded plate by locking screw or insert.The positive effect of the present invention is：Ejector pin is additionally arranged, ejector pin spring, stripping force is provided by spring, when metal plate part gets stuck strip, metal plate part is smoothly departed from pilot pin, ensure the production of blanking die safety and stability, not only acted as the effect of correcting positioning and eliminated the strip phenomenon that got stuck caused by metal plate part.
Description
Technical field
The invention belongs to mechanical manufacturing field, and in particular to pilot pin in uncoiling blanking mould in cold stamping.
Background technology
As modern production continues to develop, the also development of automobile industry is swift and violent, and automobile has been come into our daily life.Car panel die industry becomes the powerful backing of automobile manufacture industry, and supply is all increasing every year, and in modern metal plate cold stamping production, common manual line is gradually eliminated by industry, the substitute is automation and transmission mask production line.Automation and transmission mask production line production be all by a product line group into, manipulator, robot folder, send part, overall process need not be participated in manually substantially, and production efficiency greatly improves, and product quality further improves, reduce manually-operated error, follow-up workload is reduced, it is cost-effective, improve profit.It is uncoiling blanking mould and uncoiling blanking production line and the automation stable mass production wherein for blanking process provides possibility.Uncoiling blanking mould is derived from transmission mask production line, and production process is similar with multistation, and production process can simply be described as：Coiled strip is sent in mould by opening up material machine, and tablet is fed by the program being previously set, and the distance that we feed every time is referred to as its step pitch, step by step, it is incremental, to the last go out finished product, board is sent out by transmission belt, and then cased, all work is completed by the program set.Because the step pitch of transmission has certain error, at this moment require the device of correcting positioning, be arranged in the position of a work step punching, behind work step utilize this hole, metal plate part is corrected, positions and feeds the error of step pitch to reduce.The pilot pin of the device positioned in the prior art as correcting, to be fixed on the pin on the upper molded plate or insert of blanking die, although correcting positioning can be completed, but due to burr or alignment pin clearance issues, metal plate part and pilot pin can not separate at once, metal plate part can be stuck on pilot pin, and namely what is often called gets stuck, strip phenomenon.So as to which the operating efficiency of transfer matic mould can be influenceed, upset work rhythm, influence product quality, or even meeting mold damage is in itself, influences mold work efficiency and work quality problem.
The content of the invention
It is an object of the invention to provide a kind of self-discharging pilot pin, for uncoiling blanking in cold stamping, overcomes disadvantages mentioned above existing for existing pilot pin.
The self-discharging pilot pin of the present invention, including the cylindrical pilot pin pin with conehead, improvements introduced be：There are ring convex in the middle part of pin, have in ring convex several coaxial with pin, circle distribution, penetrate the ejector pin pilot hole of ring convex, have in ejector pin pilot hole and the dynamic cooperation in hole, tail end has the ejector pin of shoulder, there is the compression spring being enclosed on pin in the ring convex above section of pin, compression spring pressure holding is on the shoulder of ejector pin, the fixed cover for surrounding spring is installed outside spring, there is pin punched out at bottom on fixed cover, there is spring collar fitting recess the pin end for passing bottom on fixed cover, elastic wire collar fixed cover being locked on pin is installed in collar fitting recess, spring is locked on pin by the fixed cover being locked in by steel wire collar on pin.
The self-discharging pilot pin of the present invention preferable mounting means on upper molded plate has：
A, locking type：Have on ring convex cylinder and matched, start from the cylinder groove of ring convex lower end with locking screw cylinder head of a nail side, is assembled to by locking screw on upper molded plate；
B, it is forced：The shoulder of evagination is formed in ring convex, by having the insert of ring convex pilot hole and insert trip bolt that pilot pin press-in is assembled on upper molded plate.
The pilot pin of the present invention is not limited to both the above mounting means, however not excluded that the mechanical fasteners mode that use in the prior art and prior art are enlightened on the premise of precision is ensured, do not influence ejector pin action.
The present invention the course of work be：Upper mould moves down, pilot pin guide first, mold work, and tablet pushes ejector pin, ejector pin moves down, and ejector pin moves down middle compression spring accumulation of energy, treats that mold work finishes, and upper mould upwardly opens, compression spring discharges, and passes to ejector pin material returned power, ejector pin material returned power is acted on the metal plate part of positioning hole border.Overcome the jam formed between metal plate part and pilot pin by reasons such as burrs, be instantly separable from metal plate part and pilot pin
The positive effect of the present invention is：Former pilot pin is by transformation, ejector pin is additionally arranged in pin working portion periphery, pin bottom suit promotes the spring of ejector pin, stripping force is provided by spring, when metal plate part gets stuck strip, the pressure of spring uniformly passes to metal plate part by ejector pin, make metal plate part around positioning hole by uniform material returned power, so that metal plate part smoothly departs from pilot pin, ensure the production of blanking die safety and stability, the effect of correcting positioning is not only acted as, and eliminate the strip phenomenon that got stuck caused by metal plate part, so that mould production is smooth, it is stable, safety, effectively improve product quality, improve production efficiency.
