Abstract
The utility model discloses a stamping die with rolling shafts. The stamping die with the rolling shafts comprises an upper die and a lower die. The upper die protrudes in U-shaped mode, and the lower die is a U-shaped groove and is matched with the upper die. Openings at two sides of the lower die are hinged with rolling shafts, and the distance between the two rolling shafts is lower than the distance between openings of the lower die. Horizontal places of upper surfaces of the rolling shafts are higher than upper surfaces of the openings of the lower die. The stamping die with the rolling shafts is simple in structure, the rolling shafts are arranged on the openings of the lower die, in the process of stamping, and original sliding friction between raw materials and the lower die is changed to rolling friction, so that deformation resistance is greatly reduced. Parts can normally form in a die, surfaces of the parts can be protected, and a large round angle does not need to be arranged on an entrance of a concave die, boundary dimension of the concave die is reduced, and construction cost is reduced.
Description
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of diel that the axis of rolling is installed.
Background technology
Depended on pressure machine and mould apply external force to sheet material, band, tubing and section bar etc., make it to produce plastic deformation or separation, thereby obtain the forming and machining method of the workpiece (stamping parts) of required form and size.
Diel is sliding friction between workpiece and the upper die and lower die in punching course, because the resistance that is subject to during the distortion of material relatively hard materials is very large, piece surface and counterdie surface all can be subject to scratch in various degree in deformation process, abrade the quality that can affect product when serious, traditional large stamping die solves problems and usually adopts at the larger fillet of die porch setting, height and width, the appearance and size of die all can strengthen behind the Rouno Cormer Pregrinding Wheel but arrange, the mold integral profile also strengthens, and material and manufacturing cost all will increase.
The utility model content
The technical problem that the utility model solves is: provide a kind of diel that the axis of rolling is installed for the problems referred to above, to reduce the friction between workpiece and the counterdie, dwindle the volume of mould, reduce manufacturing cost.
For reaching this purpose, the utility model by the following technical solutions:
A kind of diel that the axis of rolling is installed, comprise patrix and counterdie, described patrix becomes U-shaped projection, the U-shaped groove of described counterdie for matching with patrix, described counterdie both-side opening position is hinged with the axis of rolling, distance is less than the lower die open distance between described two axis of rolling, and the horizontal level of described axis of rolling upper surface is higher than the lower die open upper surface.
Further, be provided with guide pillar between described patrix and the counterdie.
Further, the guide pillar between described patrix and the counterdie is the slip guide pillar.
Further, described counterdie one side is provided with guide plate.
The beneficial effects of the utility model are: the utility model is the diel that the axis of rolling is installed; simple in structure; the place arranges the axis of rolling at lower die open; make the sliding friction between punching course this raw material of Central Plains and the counterdie change rolling friction into, greatly reduced the deformation drag of part, can be in the mould normal moulding of part; piece surface is protected; need not at the die entrance Rouno Cormer Pregrinding Wheel to be set, reduced the appearance and size of die, reduced manufacturing cost.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is the punching die structure schematic diagram that the axis of rolling is installed.
Among the figure:
1, patrix; 2, counterdie; 3, the axis of rolling; 4, guide pillar; 5, guide plate.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
As shown in Figure 1, in present embodiment, a kind of diel that the axis of rolling is installed described in the utility model, comprise patrix 1 and counterdie 2,1 one-tenth U-shaped projection of described patrix, the U-shaped groove of described counterdie 2 for matching with patrix 1, described counterdie 2 both-side opening positions are hinged with the axis of rolling 3, distance is less than counterdie 2 extended distances between described two axis of rolling 3, and the horizontal level of the described axis of rolling 3 upper surfaces is higher than counterdie 2 opening upper surfaces; Be provided with guide pillar 4 between described patrix 1 and the counterdie 2; Guide pillar 4 between described patrix 1 and the counterdie 2 is the slip guide pillar; Described counterdie 2 one sides are provided with guide plate 5.
Along guide plate 5 stamping parts is placed between patrix 1 and the counterdie 2 during work, patrix 1 moves downward patrix 1 and counterdie 2 extruding stamping parts along guide pillar 4 in punching course, owing to be provided with the axis of rolling 3 and the axis of rolling 3 is outstanding with respect to counterdie 2 openings at counterdie 2 opening parts, stamping parts at first contacts with the axis of rolling 3, the axis of rolling 3 is hinged with counterdie 2, the axis of rolling 3 rotates under the effect of impulsive force, and carry out sliding friction between the stamping parts, sliding friction can reduce the resistance that patrix 1 is subject in the punching course, and reduced the possibility that the stamping parts surface is scratched, like this can be in the mould normal moulding of stamping parts has been protected simultaneously; Piece surface, by follow-up trimming, part finally reaches production requirement.
What need statement is; the above-mentioned specific embodiment only is preferred embodiment of the present utility model and institute's application technology principle; in technical scope disclosed in the utility model; the variation that any those skilled in the art of being familiar with expected easily or replacement all should be encompassed in the protection domain of the present utility model.
