Problems solved by technology

[0002] At present, in the hemming technology of the body-in-white welding workshop of the automobile production plant, in order to ensure the hemming quality, the hemming speed is relatively slow in the area where the hemming transition is sharp (such as the position of the taillight of the rear cover of the hatchback), and it is difficult to adjust the hemming quality. , the speed of the existing angular push mechanism is slow, which increases the production time and makes it difficult to maintain the quality of the pre-folding. If there is a problem with the mechanism during the production process, the debugging time will be longer, which will affect the rhythm of normal production; the body-in-white welding workshop of the automobile manufacturer The provided process layout space is small, and the space occupied by the mold components and the tire mold is relatively large

Embodiment 1

[0033] A pre-hemming device such as Figure 5 As shown, it includes a turntable mechanism 4 provided with a plurality of pre-rolling stations, and each pre-rolling station is provided with a set of positioning mechanism and a set of angular push mechanism 3 .

[0034] The positioning mechanism includes a tire mold clamp 1 fixed on the pre-rolling station, and a die assembly 2 arranged above the tire mold clamp 1 . The structure of tire mold fixture 1 is as figure 1 As shown, it includes a base 104 and a tire mold 101 disposed on the base 104 . The tire mold 101 is provided with a sensor 102 and a suction cup 103 for fixing a workpiece. The structure of die assembly 2 is as figure 2 As shown, it includes a frame 201 fixed to the tire mold clamp 1, a fixing piece 205 that is rotatably connected to the frame 201 through a rotating shaft 204, and a pressing block 203 that is arranged at one end of the fixing piece 205 for pressing the workpiece. The rotating shaft 204 passes th...

Abstract

The invention relates to a pre-edge-rolling device. The pre-edge-rolling device comprises a rotary table mechanism (4) provided with a plurality of pre-edge-rolling stations, wherein each pre-edge-rolling station is provided with a positioning mechanism and an angle pushing mechanism (3); each positioning mechanism comprises a moulding bed clamp (1) fixed to the corresponding pre-edge-rolling station and a pressing mould assembly (2) arranged above the moulding bed clamp (1); the moulding bed clamps (1) are connected with the pressing mould assemblies (2) through rotary shafts (204); and eachangle pushing mechanism (3) comprises a support fixed to the corresponding pre-edge-rolling station, an angle pushing assembly arranged on the support and a driving assembly for driving the angle pushing assembly to conduct pre-edge-rolling operation. Compared with the prior art, the pre-edge-rolling speed is greatly increased, and the equipment cost is reduced.
