Description

A kind of oil filler wicket diel

Technical field

This utility model relates to machining equipment field, more particularly, it relates to a kind of automobile fuel filler bonnet cold-stamped mould。

Background technology

Its main part of the oil filler box of automobile oil filler cap is generally adopted hard material and makes, need to adopt mould separately manufactured, the automobile oil filler cap mode of production is that a point five processes is processed, it first adopts single-point plate shearing machine to implement operation one blanking processing, secondly single-point open type steam-operating forcing press is adopted to implement the processing of operation two blanking, then single-point open type steam-operating forcing press is adopted to implement the processing of operation three flange, then adopt single-point open type steam-operating forcing press to implement operation four coinging, finally adopt fixing bench drill to implement operation five tapping processing。

Using traditional processing technology, not only need number of molds to be mounted more, produce consuming time longer, but also to carry out repeatedly material allocation between multiple devices, production efficiency is relatively low, and workload is relatively big, and manufactures inconvenience。In production process, when material is stretched, mould adopts drawing bend, although decrease the mobility of material, it is prevented that fold occurs in product, but owing to it stretches abundant not, causes that product strength is not enough；Traditional cold punching die there is also in inaccurate, the sheeting process in location easily there are the problems such as secondary weighs wounded, and the quality of production of the lid that refuels a car causes a lot of uncertain factor。

Utility model content

The purpose of this utility model is in that to overcome the location that above-mentioned orthodox car fuel door production mould occurs under cold stamping production technology inaccurate, intensity is not enough, the problems such as secondary weighs wounded occurs, starts with from production mould, one is provided to be accurately positioned, the automobile fuel filler cap production mould being sufficiently tensile。

For the attainment of one's purpose, the technical scheme that this utility model provides is:

A kind of oil filler wicket diel of the present utility model, including upper die and lower die and power set；Described counterdie includes lower bolster, counterdie backing plate, stripper, embossing male die and stretching die, on lower bolster, square bolt connects counterdie backing plate, directly over counterdie backing plate, bolt connects stripper, and directly over stripper, bolt connects embossing male die, and directly over embossing male die, bolt connects stretching template；Described upper mould includes cope match-plate pattern, upper die plate and die, and under cope match-plate pattern, square bolt connects upper die plate, and immediately below upper die plate, bolt connects die；Described power set include nitrogen spring, guide pin bushing and guide pillar, and the lower end of nitrogen spring, guide pin bushing and conduit is both supported upon lower bolster upper surface, and upper end is connected with cope match-plate pattern。

As further improvement of the utility model, described embossing male die center is provided with a square projection, and projection center is provided with a circular groove, and circular groove periphery is provided with at least 3 location cutting knifes。

As further improvement of the utility model, described stretching template is provided with 2 annular boss。

As further improvement of the utility model, described die center is provided with the groove of circle, and recessed circumferential arranges at least 3 locating slots, and inside grooves is provided with some steam vents, and the diameter of steam vent is less than 3mm。

As further improvement of the utility model, described location cutting knife is all identical with position with the quantity of locating slot, the thickness 1mm～2mm less of the width of locating slot of location cutting knife。

The technical scheme adopting this utility model to provide, compared with prior art, has the advantages that

(1) a kind of oil filler wicket diel of the present utility model, stretches and arranges multiple boss in template, can make in punching course, and material stretches more abundant, so that the intensity of product is higher。

(2) this utility model adopts the location cutting knife on embossing male die and die and locating slot that upper and lower mould is accurately positioned, stretch the boss in template to can also be used for the steps such as later stage deburring, flange and play location, generally speaking achieve being accurately positioned of flitch in production process。

(3) dynamical system of the present utility model adopts nitrogen spring, relatively other dynamical systems, and nitrogen spring is provided that bigger pressure-plate-force, is suitable for the punching press of hard material。

Detailed description of the invention

For further appreciating that content of the present utility model, in conjunction with the accompanying drawings and embodiments this utility model is described in detail, but protection domain of the present utility model is not limited to this。

Embodiment 1, in conjunction with Fig. 1, a kind of oil filler wicket diel of the present embodiment, including upper die and lower die and power set。

With reference to Fig. 1, 2, 4, 5, described counterdie includes lower bolster 1, counterdie backing plate 2, stripper 3, embossing male die 4 and stretching die 5, counterdie backing plate 2 adopts and is bolted directly to above lower bolster 1, stripper 3 adopts and is bolted to directly over counterdie backing plate 2, counterdie backing plate 2 and stripper 3 are square plate, and size is identical, embossing male die 4 is bolted on stripper 3, size is identical with stripper 3, there is a foursquare projection 15 in embossing male die 4 upper surface centre, it is 40mm～50mm that projection 15 exceeds the distance of embossing male die 4, projection 15 center arranges again a circular groove, circular groove 30mm～40mm lower than projection 15, the surrounding of circular groove arranges 4 location cutting knifes 16 equally spacedly, location cutting knife 16 thickness 15mm。One piece of stretching die 5 also it is connected with above embossing male die 4, stretching die 5 is generally square, center sets a circular hollow out, prevent from colding pressing workpiece time cause secondary to weigh wounded workpiece, two not contour boss 17 are set around openwork part continuously, in punching course, this boss 17 can increase the tensile elongation of holding pad, makes holding pad intensity higher。

Including cope match-plate pattern with reference to Fig. 1, upper mould described in 3, upper mould includes cope match-plate pattern 8, upper die plate 7 and die 6, and upper die plate 7 is directly fixed with cope match-plate pattern 8 with bolt, and die 6 bolt is fixed with upper die plate 7。Upper die plate 7 is all identical with embossing male die with the size of die 6。Wherein the lower surface center of die 6 arranges a circular groove 14, the diameter of groove 14 is identical with the diameter of the projection 15 on embossing male die 4, cutting knife 16 position, groove 14 periphery correspondence location arranges the locating slot 12 that 4 width are 17mm, and groove 14 inner cross row lays steam vent 13 that 6 diameters are 1mm and steam vent 13 that 2 diameters are 2mm。

Being connected by power guide pillar 11 and nitrogen spring 9 with reference to Fig. 1, upper mould and lower plate, guide pillar 11 wraps up at the part guide pin bushing 10 contacted with lower bolster 1 and cope match-plate pattern 8, and upper mould provides power by nitrogen spring 9, coordinates guide pillar 11 to move up and down, it is achieved the processing of stamping parts。

Schematically this utility model and embodiment thereof being described above, this description does not have restricted, and shown in accompanying drawing is also one of embodiment of the present utility model, and actual structure is not limited thereto。So those of ordinary skill in the art is enlightened by it, when creating objective without departing from this utility model, design the frame mode similar to this technical scheme and embodiment without creationary, protection domain of the present utility model all should be belonged to。
