Rivet bucker spin riveting head for necking down forming of stainless steel inner barrel of roller washing machine

Abstract

The invention discloses a rivet bucker spin riveting head for necking down forming of a stainless steel inner barrel of a roller washing machine. The rivet bucker spin riveting head comprises two forming pressing plates which are used for rotationally pressing the barrel wall of the stainless steel inner barrel onto a connection boss of a plastic component in the direction from a barrel body to the two barrel openings. One ends of the two forming pressing plates are close to each other to form a spin riveting end. A spin riveting forming area for containing the connection boss of the plastic component during spin riveting is formed in the spin riveting end. A pneumatic adjusting mechanism which is used for adjusting the forming pressing plates to move in the radial direction of the connection boss and completely connecting and wrapping the barrel wall to the connection boss in a pressing mode is arranged on a transverse supporting plate. The rivet bucker spin riveting head is simple in structure, the effect that the acting force on the stainless steel inner barrel is balanced can be guaranteed through the pneumatic adjusting mechanism of the spin riveting head, the effect that the forming quality of a necking down structure is stable is guaranteed, through the conical structure formed by matching the fixed forming pressing plate with the movable forming pressing plate, the stability and precision of the stainless steel inner barrel during spin riveting are greatly improved, and the effect that the spin riveted necking down portion is standard in shape is guaranteed.

Description

technical field [0001] The invention relates to the technical field of washing machine processing equipment, in particular to a riveting head of a rotary riveting machine used for forming a stainless steel inner barrel of a drum washing machine. Background technique [0002] The drum washing machine is controlled by a microcomputer. The clothes are not entangled, the washing is even, and the wear rate is 10% lower than that of the wave washing machine. It can wash cashmere, wool, silk and other clothes, so as to achieve comprehensive washing. It can also be heated to fully dissolve the washing powder and give full play to the decontamination performance of the washing powder. High-concentration laundry detergent can be formed in the bucket, bringing ideal laundry results while saving water. Compared with wave-wheel washing machines, some drum washing machines have functions of disinfection, sterilization, drying, and drainage in addition to washing and dehydration, which me...
