Abstract
The utility model discloses a thin wall housing part bending mould belongs to tooling, aim at providing one kind and fix a position convenience, the accurate bending mould of bending angle. It includes bed die and formpiston, bed die (4) that are type shape structure are fixed on lower bolster (6), having the core of looks adaptation (3) with it in the die cavity of bed die (4) unloads rubber pad (7) in the below of lower bolster (6), fixes and passes lower bolster (6) and rubber pad (7) the contact of unloading in ejector pin (8) of core (3) bottom surface, formpiston (1) is located the top of bed die (4), and the bottom surface of this formpiston and the top surface of bed die (4) respectively have a tilt up's inclined plane. The utility model discloses the location is convenient, the bending angle is accurate, it a mould that is used for carrying on the bending to thin wall housing part.
Description
Technical field
The utility model relates to a kind of mould, particularly relates to a kind of parts of thin-wall casing bending mould; Belong to technological equipment.
Background technology
Motor shielding box cover is a kind of parts of thin-wall casing roughly in zigzag, and its two have flange to edge break.Due to complex-shaped, be all adopt the mode of first flanging bending again to process usually, but usually there is bending location difficulty defect after flanging, curved shape is inaccurate, and waster rate is high.
Summary of the invention
For the above-mentioned defect existed in prior art, the utility model aims to provide one and locates convenient, bending angle parts of thin-wall casing bending mould accurately.
To achieve these goals, the utility model by the following technical solutions: it comprises former and formpiston; Former in convex shape structure is fixed on lower bolster; Have core suitable with it in the die cavity of former, there is discharging rubber blanket the below of lower bolster, and the push rod being fixed on core bottom surface contacts with discharging rubber blanket through lower bolster; Formpiston is positioned at the top of former, and the bottom surface of this formpiston and the end face of former respectively have an acclivitous inclined-plane.
The end face of core is fixed with two alignment pins; Backing plate is fixed with between former and lower bolster.
Compared with the prior art, the utility model, owing to have employed technique scheme, adds core moving up and down in cavity impression, is provided with an acclivitous inclined-plane separately at the end face of the bottom surface of formpiston and former simultaneously; Therefore can be inclined upwardly workpiece when formpiston is depressed bending being formed accurately, thus improve product percent of pass.In addition, owing to have employed the former of convex shape structure, therefore, it is possible to control the stroke that presses down of formpiston exactly, thus the bending angle of workpiece can be guaranteed; 3rd owing to being fixed with two alignment pins at the end face of core, therefore, it is possible to utilize on workpiece two holes to position, not only accurate but also facilitate.

In figure: formpiston 1, alignment pin 2, core 3, former 4, backing plate 5, lower bolster 6, discharging rubber blanket 7, push rod 8, workpiece 9.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.
As shown in Fig. 1 ~ 5: former 4 is fixed on lower bolster) on, there is core 3 suitable with it in the die cavity of former 4; There is discharging rubber blanket 7 below of lower bolster 6, and the push rod 8 being fixed on core 3 bottom surface contacts with discharging rubber blanket 7 through lower bolster 6; The bottom surface of this formpiston and the end face of former 4 respectively have an acclivitous inclined-plane.In order to just to control the depression stroke of formpiston 1, former 4 adopts convex shape structure.When formpiston 1 presses down, the left end of workpiece 9 is bent upwards along clockwise direction under the inclined-plane acting in conjunction of the inclined-plane of formpiston 1 and former 4; When the bottom surface of formpiston 1 contacts with the step surface on the right side of former, the part that workpiece 9 is bent upwards just in time is pressed between the inclined-plane of formpiston 1 and the inclined-plane of former 4, thus can avoid curved transitions or bending defect not in place.
In order to locate convenient accurately, the end face of core 3 is fixed with two alignment pins 2 suitable with the hole (not shown) on workpiece 9.
In order to avoid lower bolster 6 damages, between former 4 and lower bolster 6, be fixed with backing plate 5.
Claims (3)
1. a parts of thin-wall casing bending mould, comprises former and formpiston; It is characterized in that: the former (4) in convex shape structure is fixed on lower bolster (6); Have core (3) suitable with it in the die cavity of former (4), there is discharging rubber blanket (7) below of lower bolster (6), and the push rod (8) being fixed on core (3) bottom surface contacts with discharging rubber blanket (7) through lower bolster (6); Formpiston (1) is positioned at the top of former (4), and the end face of the bottom surface of this formpiston and former (4) respectively has an acclivitous inclined-plane.
2. parts of thin-wall casing bending mould according to claim 1, is characterized in that: the end face of core (3) is fixed with two alignment pins (2).
3. parts of thin-wall casing bending mould according to claim 1 and 2, is characterized in that: be fixed with backing plate (5) between former (4) and lower bolster (6).
