Description

Technical Field

[0001] The utility model relates to the technical field of plate folding, in particular to a folding machine for processing an oven shell. Background Art

[0002] An oven is a sealed appliance used to bake food or dry products. It is divided into household appliances and industrial appliances. Ovens play an important role in our lives. The outer shell of the oven is the external packaging of the oven, usually made of metal or stainless steel plates. The outer shell of the oven needs to be folded during the processing to improve the structural strength at its edges.

[0003] General folding machines only have a single folding effect. When folding the metal sheet of the oven shell, it is mainly through applying pressure to the folding head to squeeze the side of the sheet, so that the side is bent. However, after that, it is still necessary to use additional stamping equipment to extrude the bent outer edge for a second time to make it fit tightly with the edge of the sheet, so as to increase the structural strength of the sheet, and the work efficiency is low.

[0022] Insert one side of the oven shell plate body 11 that needs to be folded between the folding head 2 and the movable part 4, and the cylinder 7 drives the lifting member 8 and the folding head 2 fixed thereon to move downward;

[0023] A folding knife 9 is provided at one end of the bottom of the folding head 2, and a folding groove 10 matching the folding knife 9 is provided at the top of the movable part 4. The folding knife 9 is used to press the side edge of the oven shell plate body 11 into the folding groove 10 to make it bend;

[0024] A connecting block 15 is provided on one side of the bottom of the hemming head 2 away from the hemming knife 9, and a connecting groove 14 matching the connecting block 15 is provided on one side of the movable part 4. When hemming, the connecting block 15 on the hemming head 2 corresponds to the connecting groove 14 on the movable part 4, which plays a positioning role;

[0025] The four corners of the top of the folding machine body 1 are all provided with guide sleeves 6, and the guide sleeves 6 are all provided with guide rods 23 inside, and the bottoms of the guide rods 23 are all connected to the lifting member 8, so that the lifting member 8 is more stable when lifting;

[0026] Grooves 20 are provided around the top of the workbench 3, and pressure pieces 22 are provided inside the grooves 20 through return springs 21, and the tops of the pressure pieces 22 are connected to the bottom of the movable part 4, and a punch head 12 is provided on the movable part 4, and a secondary extrusion notch 13 is formed between the punch head 12 and the workbench 3;

[0027] After that, the cylinder 7 is reset, the oven shell plate body 11 is taken out, and placed in the secondary extrusion notch 13 below, and the cylinder 7 drives the folding head 2 to move down again, so that it squeezes the movable part 4, and the punching head 12 on the movable part 4 performs secondary extrusion on the side of the bent oven shell plate body 11, so that it fits with the edge of the oven shell plate body 11. Figure 4 As shown;

[0028] The folding and pressing process can be completed by one device, thereby improving the processing efficiency of the oven shell plate body 11. When the punch head 12 performs the folding operation, the bottom of the punch head 12 forces the pressure-receiving member 22 to squeeze the return spring 21 in the groove 20 provided on the top of the workbench 3. After the pressure disappears, the movable part 4 automatically returns to its original position under the action of the return spring 21, which is conducive to the next set of folding operations.
