What are the characteristics of hippocampus rivets in the field of household appliances?
Core characteristics of hippocampus rivet (structural hippocampus pulling nail) in the field of household appliances
First, anti-seismic and anti-loosening, solving the pain point of long-term vibration and abnormal sound of household appliances (the core advantage of household appliances)
Spline lock core double-engagement structure: the nail core is provided with annular tooth patterns, and the internal groove of the riveting body is clamped on the nail core, and the nail core is completely locked after riveting, and will not fall off, rotate or move axially.
Long-term high-frequency vibration of washing machine, wall-breaking machine, air-conditioning external machine and fan makes the common open-ended pulling nail easy to loosen and produce abnormal sound; The anti-vibration ability of Haima rivet is more than doubled, and the whole machine has no loose noise after long-term use, which greatly reduces the after-sales failure rate.
The blind end forms a multi-lobe uniform bulge, which is attached to the back plate in a large area, dispersing the vibration load, and the thin plate and plastic shell are not easy to crack.
Second, blind riveting on one side to adapt to the closed/narrow assembly space of household appliances
It only needs to punch holes in the front, and the back does not need to reach out and nut gaskets. It is suitable for closed boxes of household appliances, internal brackets, laminated sheet metal, and structures whose back can not be processed (air conditioner internal machine shell, refrigerator side plate, electric control box, water heater shell).
Simplify tooling: the sheet metal assembly line of household appliances does not need turnover tooling, which shortens the assembly time, adapts to automatic riveting equipment and has high batch production efficiency.
Third, high-strength tensile and shear resistance, bearing the heavy load of home appliance sheet metal and bracket.
It belongs to structural rivets, and its tensile and shear strength is much higher than that of ordinary open-ended core-pulling rivets, and its bearing capacity is increased by about 50%. It can be used to fix thickened sheet metal, metal bearing bracket, motor base and fan frame.
The blind end bulge has a wide bearing surface and even clamping force, and it is not easy to crush the workpiece by riveting thin aluminum, galvanized sheet, ABS plastic and foamed composite plate, which is suitable for assembling various composite plates of household appliances.
The aperture filling ability is strong, which can be adapted to slightly out-of-tolerance drilling, make up for the size error of stamping hole of household appliance sheet metal, and reduce scrap.
Fourth, the material is corrosion-resistant, and it is suitable for kitchen and bathroom and wet household appliances.
Supporting materials for mainstream household appliances:
All-304 stainless steel seahorse nail: Dishwasher, washing machine, water heater, range hood, water purifier and other humid, water vapor, oily environment, rust-proof, acid-base oil-resistant, electrochemical corrosion-free, long-term use will not rust and pollute the paint/plastic shell.
Aluminum/galvanized carbon steel seahorse nail: air-conditioned indoor units, televisions, small household appliances dry sheet metal, lightweight, cost controllable.
Practical advantages:
Stainless steel models have smooth surfaces and no dead ends, and range hoods and small household food appliances are easy to wipe and clean, which meets the requirements of kitchen and bathroom hygiene.
Five, the appearance is flat, and it is suitable for the assembly of household appliances.
Round head/countersunk head are available:
Round head: the shell is spliced and decorated with panels, and the riveted surface is smooth without sharp protrusions, so as to avoid scratching hands and scratching packaging; The stress is evenly dispersed, and the sprayed shell of household appliances is not easy to lose paint and collapse.
Countersunk head: decorative cover plate and air conditioning outlet panel with flat surface are needed, and the film can be directly sprayed after riveting.
The broken section is smooth and burr-free, which will not scratch the wire harness and plastic parts inside the household appliance, and reduce the risk of short circuit and scratch.
Six, adapt to a variety of home appliance substrates, wide compatibility.
Common material combination of riveting household appliances;
Metals: galvanized steel plate, cold rolled plate, aluminum alloy, stainless steel sheet metal;
Non-metal: ABS/PC plastic bracket, foamed insulation board, composite insulation board;
Commonly used in: range hood frame, washing machine counterweight bracket, air conditioner external machine frame, refrigerator side plate, water heater inner container bracket, wall breaker metal base, electric control cabinet, fan casing.
Seven, production assembly and cost advantage
Assembly line adaptation: with pneumatic/automatic riveting gun, riveting can be completed with one key, and the assembly speed of a single piece is less than or equal to 2 seconds, which is suitable for large-scale automatic production of household appliances, with less thread locking procedures than bolt assembly.
Simplification of consumables: there is no need for matching gaskets and nuts, which reduces the types of materials and reduces the cost of storage and sorting.
Long service life: the whole machine does not need to be fastened twice in the 10-year service cycle, which reduces the after-sales maintenance cost.
Eight, the home appliance scene exclusive short board (selection attention)
The riveting tension is large, so a special high-tension riveting gun is needed, and a small manual nail pulling gun cannot be used;
The unit price is higher than that of ordinary open-ended rivets, and dry low-vibration small household appliances (small fans and remote control housings) give priority to ordinary aluminum rivets to reduce costs;
Ultra-soft and thin plastic parts need to be matched with the brim to prevent the surface from being sunken and deformed during riveting.
Summary of typical household appliances applications
Washing machine/dishwasher (damp and vibration-resistant), range hood (oil stain and corrosion-resistant), casing/fan of air conditioner (long-term vibration), electric water heater, metal frame of refrigerator, metal base of wall breaker/blender, electric cabinet of household appliances, air duct bracket of fresh air equipment.
