Automobile plate spring lug rolling device

Abstract

The invention relates to an automobile plate spring lug rolling device which comprises a handle, a movable support, a plate spring, a core shaft, a core shaft sleeve, a positioning plate, a fixed support, a rotary disc and a workbench support. The handle is connected with the movable support, the movable support is installed on the fixed support, the movable support is provided with a roller, theplate spring is arranged on the positioning plate, the core shaft is arranged inside the core shaft sleeve, the fixed support is fixed to the rotary disc, and the workbench support is fixed to the ground. The practicability is high, the equipment occupation rate can be reduced, the manufacturing cost is reduced, work time is saved, the labor intensity is lowered, product precision and quality areensured, energy conservation and environmental protection are achieved, and market requirement can be met.

Description

technical field [0001] The invention relates to an automobile accessory device, in particular to an automobile leaf spring ear rolling device. Background technique [0002] Automobile leaf spring is the main elastic element of automobile suspension system at home and abroad. During the operation of the automobile, it transmits the force and moment acting on the frame and body parts in all directions, and relieves the tire from passing through the tire due to uneven road surface and different load conditions. The impact load transmitted to the car body can relieve the vibration of the car body, which has a positive effect on ensuring the smoothness of the car, the comfort of the driver and passengers, the stability of the cargo, and the improvement of the service life of the car-related parts. At present, domestic auto parts Manufacturers generally use earphone rubbing and earphone rolling to produce leaf springs, but these devices have a common disadvantage, that is, they ca...

[0002] Automobile leaf spring is the main elastic element of automobile suspension system at home and abroad. During the operation of the automobile, it transmits the force and moment acting on the frame and body parts in all directions, and relieves the tire from passing through the tire due to uneven road surface and different load conditions. The impact load transmitted to the car body can relieve the vibration of the car body, which has a positive effect on ensuring the smoothness of the car, the comfort of the driver and passengers, the stability of the cargo, and the improvement of the service life of the car-related parts. At present, domestic auto parts Manufacturers generally use earphone rubbing and earphone rolling to produce leaf springs, but these devices have a common disadvantage, that is, they cannot roll leaf spring products with a diameter of 16mm ear holes, although all equipment can be rolled 16mm in technical parameters However, practice has proved that the mandrel below 16mm will be bent and deformed or even broken when heated, because the rigidity of such a small mandrel is not enough at all. In this case, the shape and size of the product cannot meet The requirements are specified, so the quality is difficult to guarantee

In order not to affect production, many manufacturers use equipment to roll out half of the ear hole first, and then manually complete the second half hole. They all use the method of plastic surgery, which occupies equipment and wastes manpower. The efficiency is extremely low, which seriously affects product quality and quality. Business economics, need for improvement and innovation
