Embodiment Construction

[0018] attached figure 1 The processing flow chart of a new type of steel plate hoe is to use strip steel and bar steel to punch out mechanically, and then mechanically mold them into a hoe plate and a hoe plate, and the hoe plate and hoe plate are combined by welding; the specific steps are:

[0019] A. Production of hoes

[0020] Firstly, the bar steel 1 with trapezoidal cross-section is blanked with a punching machine or cutting equipment, and the result is a long trapezoidal strip 2 with a thick end and a short side; the side of the long trapezoidal strip 2 is pressed into an arc by a hydraulic press and a mold shape of the long trapezoidal strip 3; then use the hydraulic press and the bending and winding mold twice to wind the arc-shaped long trapezoidal strip 3 into a tapered sliver 4; Welding of the winding seam, get hoe Weng 5;

[0021] B. Production of hoe boards

[0022] First place the strip steel 6 on the mold of the punching machine to punch out the flat blank ...

Abstract

The invention relates to a processing technique of a new steel plate hoe, belonging to the field of the general agricultural mechanism or agricultural tool technology. The producing technique uses belt steel and strip steel to mechanically mold a hoe plate and a hoe wedge via mechanical blanking; the hoe plate and hoe are jointed via welded connection with a high automation; the hoe is wearable with a great appearance, energy and fuel saving without smoke and dust pollution and noise pollution, which is especially suitable for the industrial production.

Description

technical field [0001] The invention relates to a processing technology of a new type of steel plate hoe, which belongs to the components, parts or accessories (A01C5 / 00) of general agricultural machinery or farm implements in the International Patent Classification (Int.C1). The blade or similar working parts are fixed on the handle On (1 / 22·) technical areas. Background technique [0002] Most of the existing industrial processing technologies for hoes are produced with scrap steel rails and floor steel as raw materials. The production process is: scrap steel rails or floor steel—cutting the material into blanks—heating at 1100°C—press punching Pit—widening and extending by mechanical force of roll forging equipment—punching trousers and trimming skirt—cutting excess edge material around——mechanical bending and arc forming of hoe board surface—heat treatment——opening hoe edge—polishing—— Paint treatment-drying-inspected finished product. The products produced with this t...
