specific Embodiment approach 1

[0020] Specific embodiment one: combination Figure 1-Figure 4 To explain this embodiment, the cross beam in this embodiment is an arc beam with a groove-shaped cross section, the outer surface of the groove bottom of the groove is the convex surface of the arc beam, and the convex surface serves as an impact curved surface; Both sides of the outer surface of the groove bottom of the groove are provided with upper ribs 1-1 and lower ribs 1-2 along its length direction. Both sides of the groove of the groove are provided with upper edges 2-1 and along its length direction. On the lower edge 2-2, the main positioning hole 3 is set in the center of the impact surface, the central angle of the arc beam is a, and the angle of a is 40°-45°. The cross beam adopts an arc design, which can deform from the first contact point of the arc when the impact force occurs to absorb the impact energy, thereby ensuring the safety of the body and personnel to the greatest extent. The main positioni...

specific Embodiment approach 2

[0021] Specific implementation manner two: combination figure 2 To illustrate this embodiment, the lower ends of the front bumper beam of the automobile described in this embodiment are respectively provided with two concave curved surfaces 5 with the same curvature avoiding other parts. The concave curved surfaces 5 can play the role of space avoidance and can be used in assembly Timely ensure the degree of coordination with other parts, thereby ensuring the stability and matching consistency of the front bumper beam and other parts during assembly, reducing labor costs. Other structures and components are the same as in the first embodiment.

specific Embodiment approach 3

[0022] Specific implementation mode three: combination figure 2 To describe this embodiment, the arc radius of the concave curved surface 5 in this embodiment is 130 mm-150 mm. The other structures and components are the same as the first or second embodiment.

Abstract

The invention relates to an automobile front bumper beam and a manufacturing method thereof, and relates to that technical field of automobile parts manufacturing. The invention aims to solve the problem that the automobile front bumper cross beam is easy to deform after impact and has poor cushioning impact ability in the prior art. The technical scheme adopted by the invention for solving the above problems is as follows: a front bumper cross beam is manufactured by adopting a rolling and stamping combination mode; the cross beam is an arc beam with a concave cross section; the outer surfaceof the groove bottom of the concave groove is an outer convex surface of the arc beam; the outer convex surface is used as an impact curved surface; the two sides of the groove bottom outer surface are respectively provided with a convex rib along the length direction of the groove, which are respectively the upper convex rib and a lower convex rib; the two sides of the groove mouth are respectively provided with an edge along the length direction of the groove, which are respectively the upper edge and a lower edge; and the main positioning hole is arranged at the center of the impact curvedsurface. The present invention is used in the manufacture of bumper beams and in the protection of automobiles.

Description

Technical field [0001] The invention relates to the technical field of automobile parts manufacturing, in particular to an automobile front bumper beam and a manufacturing method thereof. Background technique [0002] With the improvement of people's quality of life, cars are more and more commonly used, and the safety of drivers is also getting more and more attention. There are bumpers at the front and rear of the car. They are located in most areas of the front and rear of the car. The surface is designed to avoid the impact of external damage on the vehicle safety system. When the vehicle collides with other objects, the bumper It can protect some important components of the car to minimize damage. [0003] The highest probability of car collision accidents is the collision of the front of the car, which accounts for 27% of the total number of accidents. The front bumper beam is located at the front of the car. It is the first safety component to contact in the front-end colli...
