Abstract
The utility model discloses a punching mold used for an automobile back shaft support assembly trailing arm beam, and relates to a mold used for producing automobile parts. The punching mold used for the automobile back shaft support assembly trailing arm beam comprises an upper mold plate, a material pressing plate, a locating plate and a lower mold plate, wherein a mold handle is installed on the top of the upper mold plate, a curved surface is arranged on the bottom of the material pressing plate which is installed on the bottom of the upper mold plate through a discharging screw rod and a spring, and an inclined cutting edge punching head penetrating through the material pressing plate is further fixedly installed on the bottom of the upper mold plate; and the locating plate is fixedly installed on the lower mold plate, and a curved cavity which is in accordance with the curved surface of the material pressing plate is formed in the upper portion of the locating plate. The punching mold used for the automobile back shaft support assembly trailing arm beam is not only high in production efficiency, but also stable in product quality, and therefore mass production requirements can be met.
Description
Technical field
The utility model relates to a kind of mould for the manufacture of auto parts and components, particularly a kind of punching die for bracket of back axle of automobile assembly trailing arm beam.
Background technology
Bracket of back axle of automobile assembly trailing arm beam is that an end is that the straight flat tube of inclination, the other end are that the straight flat tube of level, centre are the non-uniform beam of the curved flat tube of multistage variable cross-section, this trailing arm beam is provided with a breach in the end of the straight flat tube end that tilts, have a circular hole (referring to Fig. 3～Fig. 4), its manufacture difficulty is larger on the curved flat tube of multistage variable cross-section of centre.The manufacture method of existing bracket of back axle of automobile assembly trailing arm beam generally comprises following operation: severing, gravity die core preforming, the moulding of gravity die core, shaping, cutting, boring; Wherein, the operation punching is generally to hole on drilling machine, and its production efficiency is lower, can't satisfy the demand of production in enormous quantities.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of punching die that is used for bracket of back axle of automobile assembly trailing arm beam that can satisfy production demand is provided.
The technical scheme that solves the problems of the technologies described above is: a kind of punching die for bracket of back axle of automobile assembly trailing arm beam, comprise cope match-plate pattern, holding pad, location-plate and lower bolster, described cope match-plate pattern top is equipped with die shank, described holding pad bottom has curvilinear surface, in the bottom of cope match-plate pattern, described cope match-plate pattern bottom also is installed with an oblique sword drift that passes holding pad to this holding pad by discharging screw rod and spring fitting; Described location-plate is fixedly mounted on lower bolster, and this location-plate top is provided with the curve die cavity consistent with the holding pad curvilinear surface.
Owing to adopting technique scheme, the punching die that is used for bracket of back axle of automobile assembly trailing arm beam of the utility model compared with prior art has following beneficial effect:
1. production efficiency is high:
Because the utility model comprises cope match-plate pattern, holding pad, location-plate and lower bolster, it can be directly installed on hydraulic press carries out punching to workpiece, need not to forward on drilling machine and processes, and also need not an a pair of workpiece and hole, thereby its production efficiency is higher.
2. constant product quality:
Because the utility model is to adopt mould to complete punching, therefore, its size is more stable, thereby has also guaranteed the reliability of product quality.
In sum, the utility model not only production efficiency is higher, and product quality is also more stable, thereby can satisfy production demand.
Below, in conjunction with the accompanying drawings and embodiments the technical characterictic of the punching die that is used for bracket of back axle of automobile assembly trailing arm beam of the utility model is further described.
Description of drawings
Fig. 1: the structural representation of the punching die that is used for bracket of back axle of automobile assembly trailing arm beam of the utility model.
In above-mentioned accompanying drawing, the label of each element is as follows:
The 1-die shank, 2-discharging screw rod, the 3-cope match-plate pattern, the 4-spring,
The 5-holding pad, the oblique sword drift of 6-, 7-location-plate, 8-lower bolster, 9-workpiece.
Specific embodiment
Embodiment one:
A kind of punching die (referring to Fig. 1) for bracket of back axle of automobile assembly trailing arm beam, comprise cope match-plate pattern 3, holding pad 5, location-plate 7 and lower bolster 8, described cope match-plate pattern 3 tops are equipped with die shank 1, described holding pad 5 bottoms have curvilinear surface, this holding pad 5 is arranged on the bottom of cope match-plate pattern 3 by discharging screw rod 2 and spring 4, described cope match-plate pattern 3 bottoms also are installed with an oblique sword drift 6 that passes holding pad 5; Described location-plate 7 is fixedly mounted on lower bolster 8, and this location-plate 7 tops are provided with the curve die cavity consistent with holding pad 5 curvilinear surface.
