Description

A kind of counterdie that does not damage eccentric swage

Technical field

The utility model relates to product processing mold, specifically relates to a kind of counterdie that does not damage eccentric swage, belongs to technical field of mold.

Background technology

Mould divides upper die and lower die two large divisions, and when work, relative motion occurs for both, is the predetermined shape of mould by the metal material processing being positioned between the two. Current mould has the mentality of designing of a set of comparative maturity, difference is to carry out specific aim design according to specific product difference, therefore the center of gravity of designer research often concentrates on mould and product corresponding, and has ignored in various degree some peripheral elements. Such as mould relates to transport and deposits, how to ensure to reduce the damage to mould in transport with in depositing process, prior art research is less. Meanwhile, mould is not in the time using, and upper and lower mould is often combined, and the spring of existing eccentric swage, in compressive state, if things go on like this, easily causes spring and eccentric swage to lose efficacy.

Utility model content

For prior art above shortcomings, the purpose of this utility model is to provide a kind of counterdie that does not damage eccentric swage, and this lower die structure can reduce to deposit the damage to eccentric swage in process, thereby improves its service life.

To achieve these goals, the technical solution adopted in the utility model is such:

A kind of counterdie that does not damage eccentric swage, comprise die shoe, be respectively equipped with convex body at two ends, die shoe left and right, it between two convex bodys, is counterdie main body, be respectively equipped with bumper post at each convex body upper surface front and back position, described bumper post is processed by polyurethane, and bumper post is provided with sheath outward, and sheath height is less than bumper post height so that bumper post exposes from sheath; On the convex body between two sheaths, offer the breach that upper surface and lateral surface all open wide, be provided with lead at breach middle part; On the convex body in two sheath outsides, be provided with corresponding limited post; Outside two convex bodys both ends of the surface be respectively equipped with two transport use for connecting the connecting plate of upper bolster and die shoe, connecting plate is installed in rotation on convex body outer face by shipping and reselling on another market.

Further, on connecting plate, be provided with dismountable cylinder of depositing, deposit cylinder identical with limited post diameter, be provided with alignment pin depositing cylinder lower surface center, be provided with the locating hole corresponding with alignment pin at limited post upper surface center; Deposit cylinder and be placed in the locating hole on limited post by alignment pin in the time of mold storing, deposit cylinder and in the time depositing, do not contact with die shoe to guarantee the spring on the eccentric swage on the upper bolster corresponding with die shoe with the height sum of limited post.

Compared to existing technology, the utlity model has following beneficial effect:

1, when upper and lower mould is deposited, to deposit cylinder and be placed on limited post, and can guarantee that like this spring on the eccentric swage on upper bolster will not contact with die shoe in the time depositing, spring is in free state, can avoid like this spring to lose efficacy because of long-term pressurized, thereby improve service life.

2, the mould upper and lower mould that the utility model is transported needs or deposit by connecting plate connects, and can avoid like this upper and lower mould position in transportation to misplace, thereby guarantee transportation is not damaged mould.

Detailed description of the invention

Below in conjunction with detailed description of the invention, the utility model is described in further detail.

Referring to Fig. 1, from scheming, can find out, a kind of counterdie that does not damage eccentric swage of the utility model, comprises die shoe 10, being respectively equipped with between convex body 11, two convex bodys 11 at die shoe 10 two ends, left and right is counterdie main body 12. Be respectively equipped with bumper post 13 at each convex body 11 upper surface front and back positions, described bumper post 13 is processed by polyurethane, the outer sheath 14 that is provided with of bumper post 13, and sheath 14 is highly less than bumper post 13 height so that bumper post exposes from sheath. On the convex body between two sheaths 14, offer the breach 15 that upper surface and lateral surface all open wide, be provided with lead 16 at breach 15 middle parts. On the convex body 11 in two sheath outsides, be provided with corresponding limited post 17. The outer both ends of the surface of two convex bodys 11 be respectively equipped with two transport use for connecting the connecting plate 18 of upper bolster and die shoe, connecting plate 18 is installed in rotation on convex body 11 outer faces by shipping and reselling on another market, be provided with connecting hole on connecting plate.

In upper and lower mould matched moulds, first patrix touches bumper post 13, bumper post 13 compressive deformations, and patrix continues to move downward, until touch limited post 17, patrix motion puts in place.

Further, on connecting plate 18, be provided with dismountable cylinder 19 of depositing, deposit cylinder identical with limited post diameter, be provided with alignment pin depositing cylinder lower surface center, be provided with the locating hole corresponding with alignment pin at limited post upper surface center; Deposit cylinder and be placed in the locating hole on limited post by alignment pin in the time of mold storing, deposit cylinder 19 and in the time depositing, do not contact with die shoe to guarantee the spring on the eccentric swage on the upper bolster corresponding with die shoe with the height sum of limited post 17.

Under converted products state, connecting plate is because self gravitation is in free overhang at ordinary times. Need to connect upper and lower mould time, connecting plate is upwards rotated to 180o, with the laminating of patrix outer face, then by bolt, connecting plate upper end is connected with patrix. The mould upper and lower mould that the utility model is transported needs or deposit by connecting plate connects, and can avoid like this upper and lower mould position in transportation to misplace, thereby guarantee transportation is not damaged mould.

For improving intensity, between die shoe and counterdie main body, be provided with some deep floors, all deep floors are triangular in shape and be parallel to each other.

When upper and lower mould is deposited, to deposit cylinder and be placed on limited post, and can guarantee that like this spring on the eccentric swage on upper bolster will not contact with die shoe in the time depositing, spring is in free state, can avoid like this spring to lose efficacy because of long-term pressurized, thereby improve service life. The effect that upper and lower mould is combined is shown in Fig. 2.
