Abstract
A core provided with compact core sections and used for arc processing of an automobile bumper is used for solving the problem of bloated appearance of an existing core. According to the technical scheme, the core comprises core sections and connecting plates for connecting the core sections, each core is provided with an axial connecting hole, two sides of each connecting plate are respectively positioned in the connecting holes of two adjacent core sections, and two ends of each connecting plate are hinged with the corresponding core sections via pins. Trunnions outside the core sections are omitted, dimension proportion of a portion of each core section without arc processing along the length is reduced, number of core sections of core in a unit length is increased, flexibility of the core is fine, application range of the core is widened, and cores can be applied to forming of profiles with small arc forming diameters. Further, the core has the advantages that area of wear-resistant material on the surface of each core section is maximized, wear resistance of the core section is improved, the appearance of the core is simple, manufacturing cost of the core is low, and the like.
Description
Technical field
The utility model relates to a kind of core member, especially for the online one-tenth arc processing of bumper, the compact fuse of core joint, belongs to the mechanically deform processing technique field.
Background technology
Roll-in processing is one of main method of making at present by bumper, for the bumper with near closed hollow ring, when radius of the radian was too small, depression, defective workmanship such as wrinkling can appear in its surface, for preventing this defective workmanship, need near closed hollow ring, adopt fuse.The fuse profile is identical with the product cavity shape, is linked together by bearing pin by polylith core joint.Core structures commonly used is as shown in Figure 5: core joint front and back end is the gudgeon structure, and the adjacent core joint passes gudgeon by bearing pin and connects, and two adjacent cores joints can turn an angle around bearing pin.In order to improve the durability of fuse, adopt the high-abrasive material parcel on the fuse top layer.The problem that the fuse of this conventional structure exists is that structure is compact inadequately.Owing to become the used fuse of arc will guarantee enough intensity, described pin diameter generally will be accomplished more than the 12mm, the high-abrasive material length direction of core joint mid portion will reach 42mm and could satisfy instructions for use, the size L that does not participate in into the arc part on the event core joint length accounts for whole core joint ratio and is about about 25%, and the length dimension of fuse generally will be more than 70mm.This conventional structure causes core successively apart from big, and core joint number amount is few on the unit length, and this can't satisfy processing request for becoming the bumper that the arc radius is little, intensity is high.
The utility model content
The utility model is used to overcome the defective of above-mentioned prior art and provides the compact bumper of a kind of core joint to become arc processing to use fuse, to satisfy into the bumper processing request that the arc radius is little, intensity is high.
The alleged problem of the utility model solves by the following technical programs:
The compact bumper of a kind of core joint becomes arc processing fuse, its special feature is: comprise core joint and the connecting plate that is connected each core joint in the formation, described each core joint is axially arranged with connecting hole along it, described each connecting plate both sides lay respectively in the connecting hole of two adjacent core joint, and the connecting plate two ends are hinged by bearing pin and core joint respectively.
The compact bumper of above-mentioned core joint becomes arc processing to use fuse, and the two ends upper and lower sides of described connecting hole is the horn mouth structure, and described connecting plate two ends are circular arc, leave gap value between described connecting hole and connecting plate.
The compact bumper of above-mentioned core joint becomes arc processing fuse, and described core joint is two layer composite structure, and its internal layer is the steel liner, and skin is the high-abrasive material outer lining.
The utility model becomes the fuse profile of arc processing too fat to move at the existing bumper that is used for, being unsuitable for being processed into the section bar processing problems that the arc radius is little, intensity is high improves, remove the gudgeon that is positioned at core joint outside, connecting plate is set in core joint inside, by bearing pin that connecting plate and core joint is hinged.Can reduce the dimension scale that does not participate in into the arc part on the core joint length after the improvement, the quantity of core joint improves on the fuse unit length, and the pliability of fuse is good, has widened the fuse range of application, can use in the little section bar of some one-tenth arc radiuses is shaped processing.The utility model also has the area maximization of core joint surface wear-resistant material in addition, and the wearability of core joint improves; Characteristics such as the fuse external form is simple, and processing cost is low.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the F-F cross-sectional view of Fig. 1;
Fig. 3 is the M-M cross-sectional view of Fig. 1;
Fig. 4 is a core joint structural representation;
Fig. 5 is the structural representation of conventional structure fuse.
Label is expressed as follows in the accompanying drawing: 1. core saves; 1-1. outer lining; 1-2. liner; 1-3. connecting hole; 2. connecting plate; 3. bearing pin.
The specific embodiment
Referring to Fig. 1, the utility model is made up of a plurality of core joints 1, and each core joint is connected by connecting plate 2, bearing pin 3.
Referring to Fig. 1-3, the utility model core saves 1 two ends and has abandoned gudgeon commonly used, is axially arranged with connecting hole 1-3 along it in each core joint, and described each connecting plate both sides lay respectively in the connecting hole of two adjacent core joint, and the connecting plate two ends are hinged with the core joint by bearing pin 3 respectively.
Referring to Fig. 3, Fig. 4, for guaranteeing between each core joint relatively rotating of certain angle to be arranged, the two ends upper and lower sides of connecting hole 1-3 is set to the horn mouth structure, connecting plate 2 two ends are circular arc simultaneously, leave gap value between connecting hole middle part and connecting plate, neglecting greatly of gap value neededly between the core joint relatively rotates angle and decides.
Referring to Fig. 1, Fig. 2, the utility model core joint 1 is a two layer composite structure, its internal layer is steel liner 1-2, skin is high-abrasive material outer lining 1-1, owing to cancelled gudgeon, the ratio that the size L1 that does not participate in into the arc part between each core joint accounts for whole core joint length is very little, and the area that core saves outer high-abrasive material can increase substantially, the wearability that makes fuse with become the arc quality all to be significantly improved.
