Problems solved by technology

[0004] Nowadays, people have higher and higher requirements for cars, so the requirements for the precision of various parts in the car are also getting higher and higher. However, the angle of the taillight gutter in the past is relatively large, which causes it to be installed on the car body. The large gap between the parts affects the appearance on the one hand and reduces the connection strength on the other hand

Embodiment 1

[0029] The processing technology based on the tail light trough assembly includes the following steps:

[0030] Step (1): fixing, placing the workpiece to be processed in the first mold for fixing;

[0031] Step (2): drawing, drawing the workpiece fixed in step (1), so that the workpiece forms a convex cavity;

[0032] Step (3): fixing, taking off the workpiece in step (2) and fixing it in the second mould;

[0033] Step (4): stamping for the first time, performing secondary stamping on the workpiece 1 in step (3) to form the first fillet 2;

[0034] Step (5): second stamping, performing second stamping on the workpiece 1 in step (4) to form a second rounded corner 2 , wherein the second rounded corner 2 is smaller than the first rounded corner 2 .

[0035] Wherein, the radius of the convex cavity in step (2) is 7 mm; the radius of the first rounded corner 2 in step (4) is 11 mm; the radius of the first rounded corner 2 in step (5) is 3 mm.

[0036] Such as figure 1 As sho...

Embodiment 3

[0046] The processing technology based on the tail light trough assembly includes the following steps:

[0047] Step (1): fixing, placing the workpiece to be processed in the first mold for fixing;

[0048] Step (2): drawing, drawing the workpiece fixed in step (1), so that the workpiece forms a convex cavity;

[0049] Step (3): fixing, taking off the workpiece in step (2) and fixing it in the second mould;

[0050] Step (4) stamping for the first time, performing secondary stamping on the workpiece 1 in step (3) to form the first fillet 2;

[0051] Step (5) second stamping, the workpiece 1 in step (4) is stamped a second time to form a second rounded corner 2 , wherein the second rounded corner 2 is smaller than the first rounded corner 2 .

[0052] The radius of the convex cavity in step (2) is 7.5mm; the radius of the first fillet 2 in step (4) is 12.5-13.5mm; the radius of the first fillet 2 in step (5) is 4.9mm.

Embodiment 4

[0054] Such as figure 2 and image 3 As shown, the difference between this embodiment and Embodiment 1 is that the second mold in this embodiment includes an upper mold 15 and a lower mold 14, and a base is connected to the lower end of the lower mold 14 by bolts. The upper mold 15 is connected with the hydraulic structure (not shown in the figure), and the lower mold 14 is provided with two mold cavities 16, and the two mold cavities are respectively located at both sides of the lower mold. The side of each die cavity is provided with a fixture 17 for fixing the workpiece, and the lower end of the patrix is ​​provided with a stamping head (not shown in the figure), and the end of the stamping head is spherical.

Abstract

The invention relates to the technical field of automobile part production devices, and discloses a machining process based on a taillight gutter channel assembly. The machining process comprises thefollowing steps of (1) fixing, wherein a workpiece to be machined is placed in a mold to be fixed; (2) drawing, wherein the workpiece fixed in the step (1) is drawn, and a convex cavity is formed in the workpiece; (3) fixing, wherein the workpiece in the step (2) is taken down and fixed in a second mold; (4) primary stamping, wherein primary stamping is conducted on the workpiece in the step (4),and a first circular bead is formed; and (5) secondary stamping, wherein the workpiece in the step (4) is subjected to secondary stamping, a second circular bead is formed, and the second circular bead is smaller than the first circular bead. According to a taillight gutter channel produced through the process, the size of circular beads of parts of the taillight gutter channel can be reduced, andthe requirement for cooperation with other automobile parts is met.

Description

technical field [0001] The invention relates to the technical field of auto parts production devices, in particular to a processing technology based on a taillight water tank assembly. Background technique [0002] The body of the car is mainly composed of sheet metal stamping parts welded and connected, so the surface quality and precision quality (surface difference, stop, hole) of a single stamping part have a direct impact on the precision and quality of the vehicle. In addition to the precision of a single stamping part to meet the index requirements, the quality requirements for its appearance and surface quality are not allowed to have quality problems such as cracking, wrinkling, stacking, napping, dents, and bulges. [0003] Taillights are viewed from the rear of the vehicle, and are used to indicate the existence and width of the vehicle. The gutter is to discharge the rainwater from the body along the gutter to the outside of the car, preventing water from enterin...
