Embodiment Construction
[0014] Such as Figure 2-4 Shown, the technological method of processing automobile door guide groove of the present invention, comprises the following steps:
[0015] (1) Putting the strip steel 2 to be processed with a certain width into the working area of the processing die 1 of the profile rolling equipment for profile rolling;
[0016] (2) The formed profile directly enters the bending mechanism on the horizontal plane, and the strip steel 2 is tightly pressed on the die through computer control or mechanical copying to make the workpiece close to the workpiece. The strip steel 2 is bent in place. It can be suitable for the bending circle in each plane, and a special adjustable cutting machine base can be built to realize rapid and continuous production and save labor costs;
[0017] (3) Install a set of spiral calibration devices at the outlet of the line bending circle of the cold bending unit. Through the adjustment of the calibration devices, a certain helix angle...

The invention relates to a technical method for processing an automobile door guide slot, which comprises the main technical steps of: putting band steel with certain width in a die processing work area of section rolling equipment for conducting section rolling; conducting horizontal plane round bending on the forming section which enters a horizontal plane round bending mechanism; and arranging a group of spiral calibrating devices at an on-line round bending outlet of a cold-bending unit, providing a certain spiral ascending angle by the adjustment of the spiral calibrating devices, leading the section of two-dimension radian to become a three-dimension curved surface, and then intercepting a certain length according to specifications. The technology bends the band steel into a tree-dimension space shape at one time, thus greatly reducing input costs and satisfying the demand of production in batches; the guide slot is good in forming effect, stable in quality and performance and high in percent of pass, thus having comparatively high cost performance, reducing production cost and environment pollution, and being capable of realizing fast continuous production.
Description
technical field [0001] The invention relates to a processing method for auto parts, in particular to a process method for processing an automobile door guide groove. Background technique [0002] At present, the widely used door guide grooves of auto parts are mostly rolled and stamped with galvanized sheet, and the thickness of the sheet is about 0.7mm. Since most of these products are three-dimensional, their processing methods are generally as follows figure 1 As shown, that is, the galvanized sheet is rolled and cut first, then stamped and formed, and finally shaped. The disadvantages shown in the processing process are generally more working procedures, long processing route (that is, after two forming processes and then a shaping process), the processing process is not stable enough, and the quality of the control profile has a greater impact. Difficulty, thus resulting in a low product qualification rate. Contents of the invention [0003] In view of the above def...
