Description

technical field [0001] The invention relates to the technical field of lifting and turning equipment manufacturing, in particular to a turning device. Background technique [0002] In the production process of special vehicles and other industries, displacement welding and process reversal of the workpiece are necessary. A reversal device is often used to realize the displacement of the workpiece during welding. In addition, due to the characteristics of the weldment production process, it is necessary to weld the workpiece after displacement welding. Then turn the workpiece at a certain angle, for example: in the production of the semi-trailer frame, after the reverse assembly and welding, the entire semi-trailer frame should be turned 180 degrees to facilitate the subsequent process. The existing overturning device has a single-sided rollover device with single function and low efficiency. The specific description is as follows: The first type is a single-side 90-degree si...

Problems solved by technology

The existing overturning device has a single-sided rollover device with single function and low efficiency. The specific description is as follows: The first type is a single-side 90-degree side-turning displacement welding form. The disadvantage of this device is that this displacement device can only To meet the process requirements of one side of welding, it should be used correspondingly with another symmetrical displacement welding device. The overall (180 degree) flip after welding is relatively low in efficiency, and it is impossible to realize the overall flip after welding; the second type is: a squirrel-cage flip device, which needs to be matched with the front and rear supporting roller frames. The range of workpieces to be adapted is small. Although the requirements of double-sided displacement welding can be completed at one station, it cannot meet the requirements of automatic unloading after the workpiece is turned 180 degrees after welding. In addition, the second method is the largest The disadvantage is that the workload of the civil engineering is relatively large, because it has a problem of the radius of gyration. This kind of device generally needs to be matched with the pit on the civil engineering. To use this displacement welding device, the front and rear auxiliary transition rolling table is required, and the efficiency is low. , In addition, this kind of device can't satisfy the turning over of products with irregular double sides of the workpiece, because this turning device enters and exits the workpiece by relying on the front and rear roller tables and the rollers on itself. If the workpiece is irregular, even if it can achieve 180 degrees Turning over will also encounter problems in realizing the delivery of workpieces. Another disadvantage is high manufacturing costs and relatively low efficiency, which is not conducive to flexible changes in production processes.
