Abstract

The utility model discloses a semi circular bending die comprising an upper die holder, a lower die holder, a concave die and a convex die. The concave die is fixedly connected onto the upper die holder, the lower surface of the concave die is provided with a semi circular groove, a fixing plate is connected onto the lower die holder, an ejecting plate is movably connected onto the fixing plate, the convex die is connected to the fixing plate, the upper side face of the ejecting plate is provided with a positioning groove, a convex die through holes is formed below the positioning groove, the upper end of the convex die is located in the convex die through hole, the upper surface of the convex is semi-cylindrical, and the convex die is located under the concave die. During operation, a blank is placed in the positioning groove, the upper die moves downwardly, the ejecting plate moves downwardly under the downward stress, the convex die ejects the blank into the groove of the concave die to bend for forming, the upper die moves upwardly, the ejecting plate ejects the part out of the convex die, and the part is prevented from clamping on the convex die and can be took out conveniently.

Description

Semicircular ring bending die
Technical field
The utility model relates to stamping technology field, relates in particular to a kind of semicircular ring bending die.
Background technology
As shown in Figure 4, a kind of semicircular ring that adopts sheet-metal press working to form, with bending die processing, generally, the punch of bending die is arranged on the below of upper bolster, die is arranged on the top of die shoe, rises, then product is taken off from punch after product bends with punch, but because product is stuck on punch, get product very inconvenient, more time-consuming, extend machining period.
Utility model content
Problem to be solved in the utility model is, for the above-mentioned defect of prior art, provides one to take off product convenient, saves man-hour, reduces costs semicircular ring bending die simple in structure.
The purpose of this utility model is achieved through the following technical solutions.Semicircular ring bending die, comprise upper bolster, die shoe, die and punch, described die is fixedly connected on upper bolster below, and the lower surface of die is provided with semicircular groove, the top of die shoe is connected and fixed plate, the top of fixed head is flexibly connected top board, and punch is connected on fixed head, and the upper side of top board is provided with locating slot, locating slot below is provided with punch through hole, the upper end of punch is positioned at punch through hole, and the upper surface of punch is semicircle cylindricality, punch be positioned at die under.When work, blank is placed in locating slot, patrix is descending, top board is subject to downward active force and moves down, and punch ejects blank the groove bent into shape that is pressed into die, and patrix is up, product is ejected punch by top board, and product can not be stuck on punch, so it is very convenient to take out product.
As preferably, in described die shoe, be provided with some screws, screw is through fixed head, screw is flexibly connected with fixed head, the upper end of screw is fixedly connected with top board, and the lower end of screw is flexibly connected with die shoe, and the below of screw is provided with spring, the below of spring is provided with plug screw, and plug screw is fastened on die shoe.
As preferably, the top of described upper bolster connects a die shank.
The beneficial effects of the utility model are, take off easily after product processes, and have saved man-hour, have reduced cost, have improved operating efficiency, and this design of bending die is simple, easy to operate.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the side-looking structural representation of the utility model patrix.
Fig. 3 is the top view of counterdie.
Fig. 4 is the structural representation of product.
Detailed description of the invention
Below the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
Embodiment; as shown in Fig. 1 to Fig. 3, semicircular ring bending die, is made up of patrix and counterdie; patrix comprises die shank 1, upper bolster 2, die 3; die shank is fixedly connected on upper bolster top, and the downside of upper bolster is provided with a U-shaped groove, and die basic configuration is cuboid; die is embedded in U-shaped groove; then straight pin and screw fastening for die and upper bolster, the lower surface of die is provided with semicircular groove, and this groove is through to trailing flank from the leading flank of die.Counterdie comprises die shoe 9, fixed head 10, top board 5 and punch 11, fixed head is fixedly connected on die shoe top by screw, in the middle of fixed head, be provided with a through hole, punch is arranged in through hole, punch and die shoe pass through screw fastening, the upper surface of punch is semicircle cylindricality, semi-cylindrical length direction extends along fore-and-aft direction, the top of fixed head is provided with top board, die shoe is provided with four up-small and down-big manholes, four rectangular distributions of through hole, on fixed head, be also provided with four through holes, corresponding one by one respectively with four lead to the hole site on die shoe, in each through hole, there is the through hole of a screw 6 through die shoe and fixed head, the lower end of screw is positioned at the through hole that die shoe is large, screw is fixedly connected on top board through upper end after fixed head, the through hole of screw and die shoe and fixed head is matched in clearance, the below of screw is provided with spring 7, the below of spring is provided with plug screw 8, plug screw is fastened in the through hole of die shoe.The upper side of top board is provided with locating slot 4, and locating slot is rectangular, and locating slot below is provided with punch through hole, and the upper end of punch is positioned at punch through hole, punch be positioned at die under.When work, blank is placed in locating slot, patrix is descending, top board is subject to downward active force and moves down, and punch ejects blank the groove bent into shape that is pressed into die, and patrix is up, product is ejected punch by top board, and product can not be stuck on punch, so it is very convenient to take out product.
The above is preferably detailed description of the invention of the utility model, not limits practical range of the present utility model with this.The utility model can also have other embodiment, only otherwise deviate from spirit of the present utility model, and within no matter in form what kind of conversion all drops on protection domain of the present utility model.
