Description

Technical Field

[0001] The utility model relates to the technical field of bending equipment, in particular to a plate bending device for producing stainless steel kitchenware. Background Art

[0002] Kitchen equipment refers to the equipment and tools placed in the kitchen or used for cooking. Kitchen equipment typically includes cooking and heating equipment, processing equipment, disinfection and cleaning equipment, and room and low-temperature storage equipment.

[0003] Stainless steel is one of the commonly used materials for kitchen utensils. In the production process of stainless steel kitchen utensils, most of them are produced using stainless steel plates. During the plate processing process, the plates need to be bent. After searching, the Chinese patent application number is: CN202121844595.0, which discloses a plate bending device for the production of stainless steel kitchen equipment. A stamping mechanism for bending the plate is provided at the bottom of the top plate, and a limiting mechanism for bending the plate is fixedly installed on the top of the working plate and below the stamping mechanism. A positioning mechanism for positioning the limiting mechanism is fixedly installed on the side wall of the support plate. The utility model provides a stamping lower die that is positioned by a limiting mechanism, and the limiting mechanism used to clamp the stamping lower die can be adjusted in the left and right directions and the front and back directions, thereby facilitating the positioning of stamping lower dies of different sizes, and the laser beam emitted by the positioning mechanism is located on the same horizontal plane as the bottom of the stamping upper die and the inner wall of the punching slot hole, thereby facilitating the positioning of the stamping lower die. Such a setting can not only quickly position the stamping lower die, but also prevent the stamping upper die and the stamping lower die from being misaligned.

[0004] In the above technical solution, a mold is used to stamp and bend the steel. Due to the high cost of the precise mold structure, this processing method requires a higher processing cost. There is also a simple bending device, but during the bending process, the two ends of the bent part are prone to warping up, and subsequent correction steps are required for correction. Therefore, we need to propose a plate bending device for the production of stainless steel kitchenware. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1 、 2 And 4, the utility model provides a technical solution:

[0024] A bending device for stainless steel kitchenware production plates, including a base 1, a top plate 3 and a bending mechanism for bending stainless steel kitchenware plates. A bracket 2 is welded on the base 1, and the upper end of the bracket 2 is welded with the top plate 3; the bending mechanism is located on the top plate 3, and the bending mechanism includes a connecting plate 6, a pressing head 7 located at the lower end of the connecting plate 6, and a hydraulic cylinder 5 for applying a downward pressure to the pressing head 7. The lower end of the hydraulic rod of the hydraulic cylinder 5 is fixedly connected to the connecting plate 6. The lower end cross-section of the pressing head 7 is semicircular to facilitate bending the plate. A processing table 14 for bending operations is also provided on the base 1. A bending opening 15 adapted to the pressing head 7 is provided in the middle of the processing table 14. Baffles 16 for positioning the plate are provided on both sides of the processing table 14.

[0025] During actual use, first place the stainless steel plate on the processing table 14 and between the baffles 16. The baffles 16 can effectively play a positioning role and prevent the plate from shifting during the processing. At this time, the part to be bent needs to be directly above the bending opening 15. Activate the hydraulic cylinder 5, and the hydraulic rod drives the connecting plate 6 and the pressing head 7 to move downward until the pressing head 7 presses the plate into the bending opening 15 to form a bend in the stainless steel plate.

[0026] Please refer to Figure 1-3 , during the bending process of the stainless steel plate, due to the local stress bending of the plate, the two sides of the stressed part of the plate will翘曲 and deform upward. To solve this problem, the following solution is proposed in this application:

[0027] A hydraulic cylinder 5 is fixedly installed at the center position of the top of the top plate 3. A U-shaped frame 4 is provided at the center of the bottom of the top plate 3. A pressing mechanism for positioning the plate is installed on the U-shaped frame 4. The connecting plate 6 is arranged in an inverted L shape. The lower end of the hydraulic rod of the hydraulic cylinder 5 passes through the top plate 3 and the U-shaped frame 4 and is fixedly connected to the top of the connecting plate 6. The pressing mechanism includes two groups of movable plates 8 arranged symmetrically and pressing wheels 13 installed at the ends of the movable plates 8. The movable plates 8 are arranged in an arc shape. The upper ends of the two groups of movable plates 8 are arranged alternately. A wheel seat 12 is welded to the lower end of the movable plate 8. The pressing wheel 13 is rotatably installed on the wheel seat 12. A convex column 11 is provided on the connecting plate 6. An activity slot 10 is opened on the upper arm of the movable plate 8. The convex column 11 is sequentially slidably inserted into the activity slots 10 of the two groups of movable plates 8. Clearances are provided on both arms of the U-shaped frame 4. Shaft rods 9 are provided in the clearances of both arms of the U-shaped frame 4. The middle part of the movable plate 8 is rotatably installed on the shaft rod 9.

[0028] In actual use, since the two groups of movable plates 8 are symmetrically arranged in two groups of bow-shaped designs, and the movable grooves 10 on the upper arms of the movable plates 8 are arranged correspondingly to the protruding columns 11 on the connecting plates 6, the middle of the movable plates 8 are rotatably installed through the shaft rod 9 on the cam frame 4, and the lower end of the movable plates 8 is installed with a pressure wheel 13. When the hydraulic cylinder 5 drives the pressure head 7 to descend for bending, the pressure wheel 13 contacts the two sides of the bending part of the plate, and since the movable plates 8 move around the shaft rod 9, when the pressure head 7 continues to press down, the pressure wheel 13 can continue to move away from the bending part and always press on the surface of the plate, thereby effectively avoiding warping and deformation on both sides of the stress-bearing part of the plate.

[0029] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
