Main leaf spring eye shaping equipment and processing method thereof

Abstract

The invention belongs to the technical field of automobile main leaf spring eye processing, particularly relates to the technical field of automobile main leaf spring eye shaping equipment and processing methods thereof, and discloses main leaf spring eye shaping equipment and a processing method thereof. The main leaf spring eye shaping equipment comprises a head cutting system, a spring eye system and a shaping system which are arranged on a rack, wherein the head cutting system comprises a head cutting blade; the head cutting blade is connected with a rocker arm by a ball head screw; an eccentric wheel is arranged on the rocker arm; a compressing cam is arranged on the eccentric wheel; the spring eye system comprises a transmission spindle; the transmission spindle is connected with a traction wheel by a clutch flywheel; the traction wheel is connected with splines by a traction rod; the splines are connected with a spring eye rotating roller; the spring eye rotating roller is connected with a spring eye mandrel by a pull pin spline; the shaping system comprises a shaping die; the shaping die is connected with a shaping mandrel; and the shaping mandrel is connected with a shaping transmission spindle by a sector gear and a spline.

Description

Technical field [0001] The patent of the present invention belongs to the technical field of processing the lugs of the main sheet of automobile leaf springs, and more specifically relates to the technical field of equipment and processing methods for processing the lugs of the main sheet of automobile leaf springs. technical background [0002] There are two existing leaf spring rolling ear processing technology schemes: the first hydraulic rolling ear: feeding heating (medium frequency induction furnace or natural gas furnace), R die cutting head, positioning at the center hole, hydraulic cylinder rotation for rolling ears, This kind of processing method is currently widely used, with poor roundness of the ear holes, large fluctuations in the center distance between the two ear holes, complex hydraulic ear rolling equipment, and large investment; the second artificial ear rolling: heating by feeding (medium frequency induction furnace or natural gas) Furnace), punching machine ...

Problems solved by technology

[0002] There are two existing leaf spring rolling lug processing schemes: the first hydraulic rolling lug: feeding heating (intermediate frequency induction furnace or natural gas furnace), R die-cutting head, positioning with the center hole, hydraulic cylinder rotation to roll the lug, This processing method is currently widely used, but there are disadvantages such as poor roundness of the ear holes, large fluctuations in the center distance between the two ear holes, complex hydraulic ear rolling equipment, and large investment; the second artificial ear rolling: feeding heating (intermediate frequency induction furnace or natural gas) Furnace), punching machine to cut the head, half-wrap the ears, take the ear hole as the center, and rotate it pneumatically or manually to form the ear. This kind of ear hole forming method is simple, the production efficiency is low, the labor intensity is high, and the quality is unstable. It is generally used for small-scale processing. In addition, the above two processing schemes, because there is no shaping process, the rolled out earholes have different degrees of bell mouth, and the perpendicularity between the earholes and the reeds does not meet the requirements

When the bushing is pressed in the ear hole in the subsequent process, the bushing can be broken; when the leaf spring assembly is assembled with the vehicle frame, the leaf spring ear hole and the frame hanging ear hole are not concentric, which makes it difficult to assemble the ear hole shaft pin and the labor intensity of the workers. increase, and may cause abnormal noise of the car suspension
