Abstract
The utility model discloses a bending and molding die of a U-shaped rod of an automobile. Two parallel rod portions are arranged on the U-shaped rod. The bending and molding die comprises a male die and a female die. A punch portion protruding downwards is arranged on the male die, the bottom face of the punch portion is provided with an arc face and two inclined faces connected with two sides of the arc face, a female die cavity matched with the punch portion of the male die is arranged on the female die, and a groove in the same shape as the bent U-shaped rod is arranged on the top face of the female die cavity. Compared with the prior art, the U-shaped rod is arranged on the bending and molding die to be bent and machined, machining efficiency is obviously improved, time and labor are saved, and the bending device is simple in structure and convenient to use.
Description
Technical field
The utility model relates to mould, and specifically, the utility model relates to the U-shaped bar bending and molding of a kind of automobile mould.
Background technology
In auto parts and components, a kind of U-shaped rod member is arranged, its structure as shown in Figure 1, two bar portions that parallel also require to have identical bending on this U-shaped bar 1, the Bending Processing of carrying out this U-shaped bar 1 at present is to adopt the method for manually knocking by pincers worker, with a little the bending of two bar portions of U-shaped bar 1, this processing method working (machining) efficiency is low, wastes time and energy.
The utility model content
Technical problem to be solved in the utility model is the U-shaped bar bending and molding of a kind of automobile mould, to reach the purpose of the Bending Processing efficient that improves U-shaped bar.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: the U-shaped bar bending and molding of a kind of automobile mould, have two bar portions that parallel on the U-shaped bar, described bending and molding mould comprises punch and die, be provided with the punch of downward protrusion at punch, the bottom surface of punch has arc surface and is connected two inclined planes of arc surface both sides, die is provided with the matrix cavity suitable with the punch of punch, is provided with the groove identical with the shape of U-shaped bar after the bending at the end face of matrix cavity.
Angle between two inclined planes on the described punch is 121.3 degree.
The utility model adopts technique scheme, compared with prior art, U-shaped bar is placed on carries out Bending Processing on this bending and molding mould, and working (machining) efficiency obviously improves, and is time saving and energy saving, and this Bending Mould is simple in structure, easy to use.
Description of drawings
Fig. 1 is the structural representation of U-shaped bar;
Fig. 2 is the structural representation of this bending and molding mould;
Fig. 3 is the vertical view of the die of this bending and molding mould;
Mark among the above-mentioned figure is: 1, U-shaped bar; 2, cope match-plate pattern; 3, punch; 4, die; 5, lower bolster; 6, groove; 7, punch.
The specific embodiment
Be illustrated in figure 2 as the U-shaped bar bending and molding of a kind of automobile of the present utility model mould, it comprises cope match-plate pattern 2, lower bolster 5, punch 3 and die 4, and punch 3 is fixed on the cope match-plate pattern 2, and die 4 is fixed on the lower bolster 5.The structure of U-shaped bar 1 as shown in Figure 1.Be provided with the punch 7 of downward protrusion at punch 3, the bottom surface of punch 7 has arc surface and is connected two inclined planes of arc surface both sides, be formed with fillet on the punch 7, die 4 is provided with the downwards recessed matrix cavity suitable with the punch 7 of punch 3, the shape of matrix cavity is identical with the shape of punch 7, is provided with the groove 6 identical with the shape of U-shaped bar 1 after the bending at the end face of matrix cavity, as shown in Figure 3, after punching press was finished, U-shaped bar 1 fell into the groove 6 on the matrix cavity.
Angle between two inclined planes on the punch 7 is 121.3 degree, angle between two inclined planes on the matrix cavity of die 4 also is 121.3 degree, the fillet of punch 7 bends two bar portions of U-shaped bar 1, matching with the inclined plane on the die 4 all the other positions pressings of two bar portions of U-shaped bar 1 in inclined plane on the punch 7, prevents distortion.
By reference to the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
Claims (2)
1. the U-shaped bar bending and molding of automobile mould, have two bar portions that parallel on the U-shaped bar, described bending and molding mould comprises punch and die, it is characterized in that: described punch is provided with the punch of downward protrusion, the bottom surface of punch has arc surface and is connected two inclined planes of arc surface both sides, described die is provided with the matrix cavity suitable with the punch of punch, is provided with the groove identical with the shape of U-shaped bar after the bending at the end face of matrix cavity.
2. the U-shaped bar bending and molding of automobile according to claim 1 mould is characterized in that: the angle between two inclined planes on the described punch is 121.3 degree.
