The automobile seat belt is a safety device for restraining a passenger in a collision, and for avoiding a secondary collision between the passenger and a steering wheel, an instrument panel, or the like in the collision or a crash injury caused by the passenger being out of the vehicle in the collision. A vehicle seat belt, also known as a seat belt, is one type of occupant restraint device. The automobile safety belt is the acknowledged cheapest and most effective safety device, and the safety belt is forcibly equipped in many countries in vehicle equipment, wherein a shaft core is an important part in the automobile safety belt, but the existing shaft core adopts forging or forging and machining processes, but the precision of the forging process is not high, the performance of the shaft core is influenced, and the forging and machining processes are very costly and have high cost.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: in order to solve present axle core and make very consumedly, the manufacturing accuracy is not high, influence the performance problem of axle core, the utility model provides an automobile installation area is around tight device with tooth form stamping forming die frock in the middle of the axle core, middle tooth form stamping forming die frock includes the upper die base, establish the last die cavity below the upper die base, the die holder and establish the lower die cavity in the die holder top, it is equipped with the slotting tool to go up the die cavity both sides, through using the verification, moreover, the steam generator is simple in structure, high durability and convenient use, the precision of making out is higher, the setting of slotting tool can avoid lower tubular column many materials, the material only can extrude in the lower die cavity, the effectual present axle core of having solved makes very consumedly, the manufacturing accuracy is not high, influence the performance problem.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a car installation area is around tight device with middle profile of tooth stamping forming die frock of axle core, includes the axle core and establishes middle profile of tooth stamping forming die frock on the axle core, the axle core includes middle profile of tooth portion, establishes the axle core head portion of middle profile of tooth portion top and establishing the lower tubular column of middle profile of tooth portion below, middle profile of tooth stamping forming die frock includes the upper die base, establishes last die cavity, die holder and the establishment of upper die base below are in the lower die cavity of die holder top, the lower die cavity both sides are equipped with the slotting tool.
Further, the bright belt of the middle tooth-shaped part is 75% -90%.
Further, the bright band of the intermediate tooth portion is 90%.
The bright belt in the utility model is a cut surface, and the opposite is a tearing surface.
The utility model has the advantages that: the utility model provides a tooth-shaped stamping forming die frock in middle of car installation area is around tight device with axle core, middle tooth-shaped stamping forming die frock includes the upper die base, establish the upper die cavity below the upper die base, the die holder and establish the lower die cavity above the die holder, upper die cavity both sides are equipped with the slotting tool, through using the verification, simple structure, high durability and convenient use, the precision of making out is higher, the setting of slotting tool can avoid lower tubular column many materials, the material only can extrude in the lower die cavity, the effectual manufacturing of having solved current axle core is very consumeed, the manufacturing precision is not high, influence the performance problem of axle core; the bright band of the middle tooth-shaped part is 75-90%, which is only about 35% higher than that of the bright band in the industry, so that the performance is greatly improved; the slotting tool is known in the prior art and therefore no description of its structure is given in this patent.
Drawings
The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a schematic view of a tooling structure of a shaft core of the present invention;
fig. 2 is a schematic structural view of the shaft core of the present invention;
fig. 3 is a schematic structural view of the middle tooth portion of the present invention.
In the figure: 100 shaft cores, 101 middle tooth-shaped parts, 102 shaft core heads, 103 lower pipe columns, 200 middle tooth-shaped punch forming die tools, 1 upper die holder, 2 lower die holders, 3 guide pillars, 4 upper die cavities, 5 lower die cavities and 6 slotting tools.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
The utility model provides a car installation area is around tight device with middle profile of tooth stamping forming die frock of axle core, includes axle core 100 and establishes middle profile of tooth stamping forming die frock 200 on axle core 100, axle core 100 includes middle profile of tooth portion 102, establishes the axle core head 102 of middle profile of tooth portion 101 top and establish the lower tubular column 103 of middle profile of tooth portion 101 below, middle profile of tooth stamping forming die frock 200 includes upper die base 1, establishes last die cavity 4, die holder 2 and the establishment of 1 below of upper die base 2 top lower die cavity 5, 5 both sides of die cavity are equipped with slotting tool 6 down.
In a preferred embodiment, the bright band of the intermediate tooth 101 is 75% to 90%.
The utility model discloses an go up the shape that the form of die cavity 4 and middle profile of tooth portion 101 contact is with middle profile of tooth portion 101 looks adaptation.
The lower tubular column (like the arrow point of two bisymmetry) that the axle core needs processing tooth is lived to the die cavity, during the product punching press, goes up the die cavity and down extrudees the material to the tubular column from last, and the material is extruded lower die cavity and is formed the cusp, considers the material and down walks, and many materials can appear in the lower tubular column, and this structure goes up the die cavity both sides again and increases the slotting tool, can avoid the many materials of lower tubular column, and the material only can extrude lower die cavity in, and the bright area of flank of tooth reaches 75% -90%.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
