Description

Bridge skin

Technical field

The utility model relates to automobile, loader parts manufacturing technology field, is specifically related to the bridge skin for automobile, loader.

Background technology

At present, for the bridge skin of automobile, loader, be that seven minor structures being made by steel plate are welded, these seven minor structures are respectively that two bridge skins that are arch, four triangular plates and one are hemispheric wooden dipper shell.The deficiency existing is: manufacturing process is complicated, the expense of taking a lot of work material, and inefficiency, manufacturing cost is high, weld seam is many, and intensity is low, and bearing capacity is poor, during use, bridge sheet is all stressed up and down, the easy stressed crackle of weld seam, thus cause oil impregnate and bridge intracutaneous chamber component wear to damage.In addition, bridge skin fillet in normal shear is many, affects attractive in appearancely, is unsuitable for senior vehicle and uses.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of bridge skin that can overcome above-mentioned deficiency, its bridge sheet and bridge wooden dipper are the integral structure through particular manufacturing craft stretching extrusion molding by a block plate, its manufacturing process is simple, the work efficiency of welding forming is enhanced about more than once, and has saved welding cost, has extended service life, intensity is high, load-carrying capacity is large, stressed not yielding, has eliminated the defect that weld cracking, oil impregnate and component wear damage.

In order to solve the problems of the technologies described above, the utility model is taked following technical scheme:

Bridge suitcase is drawn together bridge wooden dipper, bridge sheet; Wherein: bridge wooden dipper and bridge sheet are the integral structure through particular manufacturing craft stretching extrusion molding by a block plate; The centre portion of described bridge sheet is to take the arch configuration that bridge wooden dipper is center of symmetry, and this arch configuration is centered around the relative both sides that bridge wooden dipper is positioned at Width; End at two ends, bridge sheet left and right is respectively equipped with reducing, and the profile of this reducing is cylindrical, and its endoporus is circular hole; Between arch configuration on bridge sheet and reducing, be provided with extension two ends along its length, these extension two ends are the tubular structure being square; Described bridge wooden dipper is semisphere, is arranged in the middle of the front of bridge sheet, and this bridge wooden dipper is the bottom of circular arc and the arch configuration of bridge sheet connects as one; At the position corresponding with bridge wooden dipper, the back side of bridge sheet, be provided with rounded uncovered and with uncovered two vees that are communicated with of above-mentioned circle, these two vees are symmetricly set on the circular uncovered left and right sides; Bridge sheet becomes one with two triangular plates that are welded in above-mentioned two vees; At the back side of bridge sheet, be symmetrically set with Y-shaped weld seam; The weld seam of this Y shape is by being the weld seam of < shape and forming near reducing and a straight weld along its length.

Between arch configuration on described bridge sheet and square tubular structure, transition is connected with plane.

Between arch configuration on described bridge sheet and square tubular structure, transition is connected with arc surface.

Compared with the prior art the utility model, has following beneficial effect:

Bridge sheet in the utility model and bridge wooden dipper are the integral structure through particular manufacturing craft stretching extrusion molding by a block plate, its weld seam is less, i.e. front no-welding-seam, and only respectively there is a Y-shaped weld seam at two ends, left and right overleaf, thereby front good looking appearance is generous, is suitable for various vehicles and uses.

Manufacturing process of the present utility model is simple, save the program of Multi-step forming and welding, the work efficiency of welding forming is enhanced about more than once, reduce working strength, saved welding cost, extended service life, intensity after steel plate is stretched improves, load-carrying capacity is large, stressed not yielding, has eliminated the defect of weld cracking, oil impregnate and component wear.

Accompanying drawing explanation

Fig. 1 is block diagram of the present utility model;

Fig. 2 is shaft side figure of the present utility model.

Part description in Fig. 1-Fig. 2:

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As Figure 1-Figure 2, the utility model comprises bridge wooden dipper 2, bridge sheet 1; Wherein:

Bridge wooden dipper 2 and bridge sheet 1 are the integral structure through particular manufacturing craft stretching extrusion molding by a block plate; Its front no-welding-seam, is only symmetrically set with a Y-shaped weld seam 14 at the back side of bridge sheet 1.This Y shape weld seam 14 is by being the weld seam of < shape and forming near reducing and a straight weld along its length.

At the position corresponding with bridge wooden dipper 2, the back side of bridge sheet 1, be provided with rounded uncovered and with uncovered two vees that are communicated with of above-mentioned circle, these two vees are symmetricly set on the circular uncovered left and right sides; Two triangular plates 15 are by being welded in above-mentioned two vees and become one with bridge sheet.This Y shape weld seam 14 by two joints of bridge sheet 1 and integrally welded with two triangular plates 15 after form.

The centre portion of described bridge sheet 1 is to take the arch configuration that bridge wooden dipper 2 is center of symmetry, and this arch configuration is centered around the relative both sides that bridge wooden dipper 2 is positioned at Width.
