Problems solved by technology

[0003] At present, most of the lawn mower engine and other parts are exposed. After a period of use, impurities, dust, rain, etc. will enter the engine motor, thereby increasing loss and serious wear. Once water enters, other exposed parts will be damaged. Rust, which is easily damaged, further deteriorates the equipment and leads to a decrease in the service life of the overall equipment

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] The dust cover is prepared by blanking punching-curved surface forming-positioning forming-cutting-punching in sequence, and the process steps are as follows:

[0022] Step 1. Blanking and punching: Cut the plate into a sheet of the size required by the product. In this embodiment, the material of the plate is a cold-rolled plate with a thickness of 1.8 mm. The sheet material has an irregular pattern. In the press, put the sheet material into the blanking punching die to prepare the substrate, and position the two sides of the sheet material into the mold for blanking. The prepared substrate is symmetrically arranged on the horizontal line Irregular shapes, such as figure 1 Shown is a schematic diagram of the blanking and punching process in the dust cover of a straddle lawn mower. There are four ears on the base plate, and the four ears are arranged symmetrica...

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.

Description

technical field [0001] The invention relates to the field of mechanical equipment manufacturing, and is applicable to the stamping and forming scheme of metal sheets, in particular to a forming process of a straddle-type lawn mower dust cover. Background technique [0002] Lawn mowers are also known as weeders, lawnmowers, lawn trimmers, etc. A lawn mower is a mechanical tool used to trim lawns, vegetation, etc., and can be used for weeding operations between orchard rows or roads, ditches, hillsides, and other areas. It is composed of a cutterhead, an engine, a traveling wheel, a traveling mechanism, a blade, an armrest, and a control part. The cutterhead is mounted on the walking wheels, the cutterhead is equipped with an engine, and the output shaft of the engine is equipped with a blade, and the blade utilizes the high-speed rotation of the engine to trim the lawn. [0003] At present, most of the lawn mower engine and other parts are exposed. After a period of use, im...
