Forming process of a straddle mower dust cover

Abstract

The invention discloses a forming process of a straddle-type lawn mower dust cover. The dust cover is prepared by blanking punching-curved surface forming-positioning forming-segmenting-punching in sequence, so as to drop the material The shape of the product is positioned, and the curved surface is stamped and formed. At the same time, the electrode on the lower layer of the mold surface is heated to a high temperature and kept warm for 30‑50s to eliminate the springback of the curved surface. At the same time, the two ears set close to the horizontal line are punched and formed. All the products are divided into two, and the two protruding ears of the semi-finished product are punched. The invention designs a stepped curved surface according to the engine motor, has a compact structure and a beautiful appearance, protects the engine motor from being eroded by impurities, dust, rain, etc., and prolongs the service life of the mower.
