Water-saving environment-friendly car washer without damaging car paint

The invention discloses a water-saving environment-friendly car washer without damaging car paint. The water-saving environment-friendly car washer comprises a water tank and a handheld car washer, wherein the handheld car washer comprises a handheld part and a washing part; the handheld part is provided with a speed regulating device driven by a motor; a gear A in the speed regulating device drives a high-speed shaft; the high-speed shaft drives a low-speed shaft through a gear B; the low-speed shaft is a hollow shaft; the washing part comprises a rotating disk and a circular hairbrush chassis; three supporting rods are arranged on the lower surface of the hairbrush chassis, two supporting rods are 21mm in length, and the other one supporting rod is 27mm in length; an inclination angle which is 8.4 degrees is formed between the hairbrush chassis and the horizontal plane; universal wheels are arranged on the lower ends of the supporting rods. Due to the design characteristic of two short supporting rods and one long supporting rod, the inclination angle is enabled to be formed by a rotary hairbrush and the surface of a car body when the rotary hairbrush is in rotary washing, so that in-time draining of girt in the rotary hairbrush can be ensured, the damage to the car paint due to long-time friction of the girt in the rotary hairbrush during washing is avoided, and the integrality and the smooth finish of the car paint are greatly protected.

Cover for covering selected portions of a vehicle

A protective cover for a vehicle that extends over the rear fender and across the back portion and rear fender portions of a vehicle to protect the vehicle body from stones, mud, soil and debris. The cover consists of a thin layer of material and is designed to be attached onto the body using a series of clamps and/or magnets. The protective cover is designed for use while the vehicle is in motion. A series of magnets are attached along the leading, lower, and upper edges of the cover. The cover has a series of bendable clamps that are bent in such a manner as to provide a snug, adjustable fit depending on the car model. The strap or adjoining piece of material that runs across the back of the car connects the two main sections covering the fenders. A separate flexible strap connects the two leading edges of the cover that runs along the inside of the vehicle, providing absolute security against fly-off. At least one small extension of the cover has a section of the bra covering the inside door jam. The extension includes an opening to fit over the door jam. On this section is the flexible or adjustable strap that runs along the inside of the car, preferably behind the passenger seats. The cover may further include a second flexible strap adjacent to the first flexible strap.

Packaging method of chalcogenide glass/zinc selenide polished lens

The invention provides a packaging method of a chalcogenide glass/zinc selenide lens. The packaging method comprises the following steps that a polyethylene electrostatic protective film is attached to the polished surface of the chalcogenide glass/zinc selenide lens, and vacuum packaging is carried out; the thickness of the polyethylene electrostatic protective film ranges from 0.01 mm to 0.05 mm; the polyethylene protective film has thousand-grade dust-free cleanliness and does not contain a chemical solvent; and a soft protective film which does not scratch a product is adopted, so that the risk of poor surface smoothness caused by scratching of the product is avoided. The PE protective film capable of being tightly attached to the surface of the product is adopted, and the risk that scratches are generated due to friction between the product and packaging materials is avoided; meanwhile, friction between the product and the packaging material can be avoided when the product is taken out of a packaging box, and direct use by customers is facilitated; and the PE protective film clings to the surface of the product, so that the product can be well prevented from fogging and oxidizing, the smoothness of the product is protected, and the customer satisfaction is improved.

A rapid hot forging process for forklift separation fork

The invention discloses a rapid hot forging forming process of a forklift release fork. The hot forging forming process can quickly produce a forklift release fork with excellent performance, and can be formed in one step, saving labor and production costs and improving production efficiency; the hot forging forming process By using hot forging equipment to forge the separation fork of the forklift, the hot forging equipment extrudes the heated raw steel through the extrusion between the shaping plate, the lower forming die and the load-bearing base to obtain the semi-finished product of the separation fork of the forklift. The automatic forming process is realized, the lower forming die is connected through the support mechanism, and the lower forming die is lifted, so that the semi-finished product of the forklift separation fork is placed on the top of the load-bearing base, and the semi-finished product of the forklift separation fork is pushed to the plate chain through the operation of the unloading cylinder. On the conveyor, the process of automatic unloading is completed; the equipment has a simple structure, and one piece of equipment can complete the forging process, and the degree of automation is high, which effectively improves the production efficiency.

Method for controlling roll bending forming arc deformation of aluminum profile with cavity

PendingCN113458207ACurved arc continuous and naturalCurved surface smoothVehicle componentsPhysicsEngineering
The invention relates to a method for controlling roll bending deformation in roll bending forming of an aluminum profile with a cavity. The method comprises the following steps: 1, according to the shape of an inner cavity of a profile to be roll-bent, the length of the profile to be bent and the bending radian, profiling steel bars of linear sections and a plurality of profiling sheets are manufactured; 2, before roll bending, the profile is loaded into a roll bending machine, the roll bending starting position is determined, and the profiling steel bar at one end, the profiling sheets and the profiling steel bar at the other end are sequentially loaded into the inner cavity of the profile; 3, the filled profile enters the roll bending machine to be subjected to roll bending; and 4, the profiling steel bars and the profiling sheets at the two ends of the profile subjected to roll bending are sequentially taken out, the profiling steel bars and the profiling sheets are loaded into the inner cavity of another profile to be subjected to roll bending, and roll bending work is repeated. According to the method, the problems that in the roll bending process of the large-section profile, the contour forming precision of a bent part is low, and the section deformation of a bent section is large can be effectively solved, the inner side face and the outer side face of the bent section are smooth, and transition between a linear section and the bent section is natural and smooth.
