Description

Technical Field

[0001] The utility model relates to the technical field of steaming and baking oven processing equipment, in particular to a steaming and baking tray riveting mechanism. Background Art

[0002] When using a steam oven to cook food, it is usually necessary to place the food on a steam baking tray and then put it into the steam oven for cooking. The steam baking tray includes a baking tray body for placing food and a bracket for installation on the inner wall of the steam oven, and the bracket is often fixed to both sides of the baking tray body by rivets. At present, a riveting mechanism is usually used to rivet the baking tray body and the bracket. The riveting mechanism in the prior art is shown in the Chinese utility model "An Improved Riveting Tool" with patent number CN202120375344.6 (authorization announcement number CN215315475U), including an upper riveting seat, a riveting base and a cylinder. The cylinder can drive the upper riveting seat to move vertically relative to the riveting base. The user first places the workpiece to be processed on the riveting base, and then the cylinder drives the upper riveting seat to move downward, so that the multiple punching rods in the upper riveting seat can simultaneously rivet the product, thereby realizing riveting processing of multiple parts of the workpiece at one time.

[0003] Although the bracket can be riveted to the baking pan body by using the above-mentioned riveting mechanism, the existing steaming and baking pans such as Figure 1 and Figure 2 As shown, the steaming and baking tray includes a baking tray body 1′ and a bracket 2′. A plurality of connecting pieces 11′ are arranged on the lower surface of the baking tray body 1′. The bracket 2′ is provided with mounting holes 21′ corresponding to the connecting pieces 11′. If the above-mentioned riveting mechanism is used to rivet the baking tray body 1′ and the bracket 2′, the punching rod needs to be moved downward to press down the connecting piece 11′, so that the connecting piece 11′ is deformed and connected to the limiting portion 22′ in the mounting hole 21′, thereby riveting the baking tray body 1′ and the bracket 2′. However, the punching rod of the riveting mechanism can only move in the vertical direction under the drive of the cylinder. If the speed or force of the punching rod moving downward is too large, the connecting piece 11′ may be folded together, so that the connecting piece 11′ may not be able to clamp the limiting portion 22′, so that the connection between the baking tray body 1′ and the bracket 2′ is at risk of loosening, thereby affecting the production quality of the steaming and baking tray. For this reason, it is necessary to further improve the riveting mechanism of the steaming and baking tray. Summary of the invention
