A crimping riveting device for bottom steel of refrigerator and its assembling method

Abstract

The invention provides a side pressing and riveting device of refrigerator bottom steel. The side pressing and riveting device comprises a supporting device, a hold-down device and pressing and riveting devices. The invention further provides an assembling method of the refrigerator bottom steel. The assembling method of the refrigerator bottom steel comprises the following steps that a bottom steel plate is arranged on the supporting device; the hold-down device moves downwards until the hold-down device tightly presses against the bottom steel plate; a left side plate and a right side plate are sequentially inserted into V-shaped grooves in the two side edges of the bottom steel plate; the pressing and riveting devices move towards each other, so that the V-shaped grooves in the bottom steel plate are tightly wrapped on the edge of the left side plate and the edge of the right side plate under the action of the pressing and riveting devices; punching pins in the pressing and riveting devices enable laminated pits to be formed in the edge of the bottom steel plate, the edge of the left side plate and the edge of the right side plate; When the assembly process is finished, the refrigerator bottom steel is taken down after the pressing and riveting devices and the hold-down device are removed. According to the side pressing and riveting device of the refrigerator bottom steel and the assembling method of the refrigerator bottom steel, it is guaranteed that the left side plate and the right side are connected with the bottom steel plate solidly without falling off, welding spots and sealing auxiliary materials are eliminated, production efficiency is improved, and the percent of pass of products is guaranteed.

Description

technical field [0001] The invention relates to the field of crimping riveting, in particular to a crimping riveting device for bottom steel of a refrigerator and an assembly method thereof. Background technique [0002] At present, the traditional refrigerator bottom steel is made of bottom steel plate, left bottom angle support iron, left bottom angle iron, right bottom angle support iron, right bottom angle iron, and one-way sheet through spot welding. The joint area between the bottom corner support iron, the bottom angle iron and the bottom steel plate is narrow and long, and there are many solder joints, which are highly dependent on the number and proficiency of the employees, and the flash joints on the joint surfaces between the solder joints are large and the sealing is not good Sealing auxiliary materials need to be pasted, resulting in high cost and low production capacity. The sub-components of the bottom steel of traditional refrigerators are mostly assembled ...

Problems solved by technology

The joint area between the bottom corner support iron, the bottom angle iron and the bottom steel plate is narrow and long, and there are many solder joints, which are highly dependent on the number and proficiency of the employees, and the flash joints on the joint surfaces between the solder joints are large and the sealing is not good Sealing accessories need to be pasted, resulting in high cost and low production capacity

The sub-components of the bottom steel of traditional refrigerators are mostly assembled by welding, and the efficiency of the solder joints is low, and the sealing is not good, and sealing accessories need to be pasted, resulting in poor product performance and low pass rate
