Detailed Description
The present invention will be described in further detail with reference to specific examples.
Example (b):
as shown in fig. 1 and 2, the method for forming the ground wire of the automobile fuel tank of the invention comprises the following steps:
firstly, a plurality of positioning holes (a middle positioning hole 211 and a right positioning hole 212) are cut in the metal material belt 2 and are used as a mold positioning basis for subsequent processing, so that the material is prevented from deviating from the original position after the processing times are more.
Two gap areas 231 are punched on the left side of the metal material strap 2, and the gap areas 231 are transition areas of the first conductive ends 12 and the connecting parts 11. The gap regions 231 are located corresponding to the gaps 122 on both sides of the final shape of the first conductive end 12.
And thirdly, cutting the outer contour of the first conductive end 12 at the left side of the metal material belt 2. The first conductive end 12 is still in a planar configuration.
And fourthly, cutting a second through hole 131 of the second conductive end 13 at the right side of the metal material belt 2.
And fifthly, forming the left side of the metal material belt into the three-dimensional shape of the first conductive end 12 in a multi-stamping mode. The first conductive end 12 now assumes the desired multi-step flat cylindrical configuration.
A first through hole 121 is cut at the middle of the first conductive end 12. The first through hole 121 serves as a reference for electrical connection of the first conductive terminal 12 to the tank of the vehicle.
Seventhly, cutting the outer contour of the second conductive end 13 at the right side of the metal material belt 2 and using the connecting part 11 as the connecting position of the metal material belt 2. Since the subsequent steps will make the first conductive end 12 and the second conductive end 13 deviate from the plane position of the metal material strip 2, the connection portion 11 can only be used as the connection position of the metal material strip 2 until the final blanking.
Allowing the two sides of the connecting part 11 to deform to a required angle in a mode of multiple punching. The first and second conductive ends 12 and 13 reach the final position.
Ninthly, cutting off the metal material belts 2 on the two sides of the connecting part 11 to enable the product to drop.
As shown in fig. 2, the positioning holes in step (r) include a positioning hole 211 and a positioning hole 212, where the positioning hole 211 is located between the materials of the connecting portion 11, and the positioning hole 212 is located between the materials of the second conductive end 13. The middle positioning hole 211 is used as a positioning reference for the material around the connecting portion 11, and is responsible for the material positioning in all steps. The right positioning hole 212 is used as a positioning reference for the peripheral material of the second conductive end 13, and is responsible for the right positioning in the step (iv) and the step (c).
As shown in fig. 1 and 2, in the step (r), a deformation allowance hole 221 is punched, and the deformation allowance hole 221 is located within the first through hole 121. The deformation reserved hole 221 is used as a reference for the left side of the metal strip 2 in the third step, but a certain machining allowance is reserved for material deformation, and the edge of the deformation reserved hole 221 is modified into the shape of the first through hole 121 in the sixth step.
As shown in fig. 2, a left protrusion 241 is left on the left side of the continuous portion 24 of the metal strip 2, a right protrusion 242 is left on the right side of the continuous portion 24 of the metal strip 2, and the left protrusion 241 and the right protrusion 242 are bent in step b to serve as a lateral reference. Left and right projections 241, 242 will help locate the material of continuous portion 24, and more accurately in the presence of pilot hole 211.
What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention.
