Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples.

Example 1

The technical proposal of the utility model is as follows: blanking (cutting holes and notches), machining long edges of purlines by a machine, rolling circles, machining short edges by a flanging machine and welding by a robot.

The equipment scheme is as follows: the bin sheet automatic production line equipment is characterized in that automation equipment replaces manual work to complete bin sheet feeding, laser cutting, cold rolling, rounding, bending, welding and other operations, and comprises an automatic feeding and discharging gantry truss, a laser discharging work station, a rolling mill, a roller line, a rounding work station, a bending work station, a carrying robot, a robot welding work station and the like, and is shown in figure 3.

Specifically, the working principle is as follows:

the material trolley is stopped at a material supplementing station, manual material supplementing is carried out, and in order to ensure certain precision, a positioning block is arranged on the material trolley to ensure the initial precision of the material; the material trolley is shown in a plan view in figure 4.

After the material supplementing is finished, the material trolley is controlled by the central controller to run to a material loading station, and the gantry truss is controlled by the central controller to hoist the plate material to the workbench of the laser cutting machine. The gantry truss is fixed in the X direction, and the material taking precision in the X direction is ensured by the installation positions of the truss and the feeding trolley; the material taking precision of the gantry truss in the Y direction is determined by the motion precision of the gantry truss, so that the motion precision is ensured by adopting a digital control mode.

And a sucker is arranged below the gantry truss. If the vacuum chuck is adopted, the safety is not high, and the electromagnetic chuck is adopted to easily suck the lower plate of the plate to be processed by mistake, so that the inconvenience of batch processing is caused. Therefore, a hybrid form of vacuum chuck and electromagnet chuck is adopted. When the steel plate is adsorbed, the vacuum chuck works firstly, the plate to be processed is adsorbed away from the lower plate for a certain distance, and when the electromagnetic chuck cannot act on the lower plate, the electromagnet is electrified to release the vacuum chuck, so that the safety of hoisting the steel plate is ensured; the suction cup mounting is shown in figure 5.

The laser cutting machine workbench adopts an exchange workbench mode for ensuring the production efficiency, and when one workbench cuts, the other workbench is matched with the gantry truss to carry out loading and unloading operation.

After the laser cutting machine finishes cutting, the workpiece is placed on the front roller way by the gantry truss, and is sent into the purlin machine by the front roller way, and two 90-degree hems in the length direction of the rolling bin sheet are rolled. In consideration of production efficiency, the purlin machine is adopted, and after the workpiece passes through the purlin machine, rolling is completed. The working principle of the purlin machine is shown in figure 6.

And conveying the workpiece subjected to flanging forming by the purlin machine to a rounding machine through a rear roller way, and performing roll forming by the rounding machine. Because the straight sections at the two ends of the three-roller rounding machine are longer, profiling is needed subsequently, the requirement of products cannot be met, and the straight sections of the four-roller rounding machine are shorter and can be ignored on warehouse sheet products, the four-roller rounding machine is adopted. The types of the company warehouse sheets are three at present, the subsequent product expansibility needs to be considered, and in order to facilitate production conversion and stabilize the product quality, a numerical control four-roller rounding machine is determined to meet the production requirement. The rollers of a standard rounding machine are smooth surfaces, and the products to be processed are flanged, so that the rounding machine needs to be customized, and an open ring groove is formed in the lower roller of the rounding machine to meet the requirements of product processing. The specific structure is shown in fig. 7.

After rounding, the carrying robot moves forwards to the rounding machine through the seventh shaft, grabs and lifts the workpiece by using the grabbing and lifting tool, moves to the flanging machine, and sends the workpiece to the flanging machine for flanging and forming.

The short edge of the warehouse sheet of the company is of a C-shaped structure. If a common flanging machine is adopted for processing, the carrying robot needs to follow up according to the flanging action, the height of a formed workpiece is higher, and the safety is poor. And the carrying robot needs a longer arm span and has larger investment. In order to solve the problem, the scheme determines to adopt a flanging machine to process, the robot grabs and lifts the workpiece to be immobile during flanging, and the flanging machine moves correspondingly, so that the scheme is simplified, and the investment is saved.

The flanging machine is used for positioning the end part of the long bent edge to perform first flanging, the robot feeds materials again after finishing the first flanging, the workpiece is turned over for 180 degrees after finishing the second flanging, and the flanging at the other end is finished. The specific working principle is shown in fig. 8.

And after the flanging is finished, the carrying robot sends the workpiece to the welding station through the seventh shaft, and four-corner welding is finished by the welding robot.

And manually transferring the welded bin sheet to a storage area.

It should be finally noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit the protection scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
