Abstract
The invention discloses a damper connecting bracket comprising a bottom plate and arc wing edges. A round hole, two rectangular holes for rounding and an oblong hole are formed in the bottom plate in sequence; a through hole is formed in the center of each arc wing edge, the arc peripheral profile of each arc wing edge comprises a first tangent line, a first arc line, a second arc line, a third arc line, another second arc line, another first arc line and another first tangent line which are connected pairwise; each first tangent line is an outer tangent line of the corresponding first arc line. Compared with the prior art, the damper connecting bracket has the advantages that each arc outer edge of the damper connecting bracket is divided into multiple arcs which are sequentially connected, and convenience is brought to machine of the arcs during blanking and punching; particularly when a large number of the damper connecting brackets are machined, time and labor can be saved, and steel raw materials are saved.
Description
Technical field
The present invention relates to technical field of automobile, particularly relate to a kind of bumper connection bracket.
Background technology
Bumper and spring integrate by automobile absorber, for bearing the weight of driving engine, vehicle body, domain, goods and passenger, simultaneous buffering and and due to impact shock that the speed of a motor vehicle, road excitation cause in vehicle traveling process of decaying, spring lower seat is as the important load bearing element of column support type bumper, its reliability is not only related to vehicle running smoothness, is also related to driving safety.
Connection bracket is part important in bumper, and connection bracket requires that it has the outer rim of arc, and carrying out it, difficulty in mechanical processing process is comparatively large, is difficult to make satisfactory arcing outer edges.
Summary of the invention
The object of the invention is the technological deficiency for existing in prior art, and a kind of bumper connection bracket being convenient to process is provided.
The technical scheme adopted for realizing object of the present invention is: a kind of bumper connection bracket, it is characterized in that comprising base plate and arc wing edge; Described base plate has successively a circular hole, the rectangular opening of two roundings and a slotted hole; The center of described arc wing edge has through hole, described arc wing edge arc-shaped circumference profile comprise successively and the first tangent line connected between two, the first camber line, the second camber line, the 3rd camber line, the second camber line, the first camber line and the first tangent line; Described first tangent line is the outer tangent line of described first camber line.
Preferably, described circular hole is the slotted hole identical with described slotted hole shape, and such two slotted holes can realize the bidirectional trimming of bumper connection bracket.
Described rectangular opening is the rectangular opening of rounding.
Compared with prior art, the invention has the beneficial effects as follows: the arcing outer edges of bumper connection bracket is decomposed into multiple arc, and connects and composes successively, when being convenient to blanking punching press, it is processed, especially during this parts of a large amount of processing, can be time saving and energy saving, save the use of steel raw material.

Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Embodiment:
Be illustrated in figure 1 a kind of bumper connection bracket, it is characterized in that comprising base plate 1 and arc wing edge 2.
As shown in Figure 2, described base plate 1 has successively rectangular opening 12 and a slotted hole 13 of a circular hole 11, two roundings; The connection bracket of existing product comprises two the present invention changes one of them circular hole into slotted hole 13 for bolted circular hole 11 and two rectangular openings 12, is to be finely tuned by the fixed position of slotted hole 13 pairs of bolts, making it connect compactness better.
In addition, change described circular hole 11 into the slotted hole identical with described slotted hole 13 shape, such two slotted holes can realize the bidirectional trimming (accompanying drawing omission) of bumper connection bracket.
As shown in Figure 3, the center of described arc wing edge 2 has through hole 21, described arc wing edge 2 arc-shaped circumference profile comprise successively and the first tangent line 22, first camber line 23, second camber line 24 connected between two, the 3rd camber line 25, second camber line 24, first camber line 23 and the first tangent line 22; Described first tangent line 22 is outer tangent lines of described first camber line 23, and the other end of the first tangent line 22 is connected with the outer rim of base plate 1.
In addition, in Fig. 2, described rectangular opening 12 is the rectangular opening of rounding, and this can be avoided causing scuffing to miscellaneous part when being that miscellaneous part connects.
The arcing outer edges of bumper connection bracket is decomposed into multiple arc by the present invention, and connect and compose successively, when being convenient to blanking punching press, it is processed, as shown in Figure 4, for the birds-eye view of the bumper connection bracket after blanking, wherein multiple camber line is fast and easy blanking forming.When bumper connection bracket after shaping processes this parts especially in a large number, can be time saving and energy saving, save the use of steel raw material.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
