Steel garden shovel and production technique thereof

Abstract

The invention discloses a steel garden shovel, comprising a shovel board and a tubular sleeve; the steel garden shovel is characterized in that a neck part which is extended outside of the shovel board and used to connect with the tubular sleeve is arranged on the shovel board; the shovel board and the neck part are of integrally molded structure; the tubular sleeve is a tubular component, and a connecting part is arranged at the front end of the tubular sleeve and used to interconnect with the neck part of the shovel board; and the neck part of the shovel board is jointed with the connectingpart of the tubular sleeve, so that the shovel board can be combined with the tubular sleeve. The invention changes the split structures of the triangular tie space of the garden shovel, the shovel board and other part of the tubular sleeve into an integrally molded structure, so as to not only greatly increase the load force of the garden shovel, but also largely reduce the working hour for polishing and grinding, improve the productivity and reduce the production cost. The invention also discloses a production process of the steel garden shovel.

Description

technical field [0001] The invention relates to a gardening shovel and a production process thereof, in particular to a steel gardening shovel formed by stamping and welding and a production process thereof. Background technique [0002] The existing steel gardening shovels are roughly divided into stamping welding forming, integral stamping forming, conjoined stamping forging forming, roll forging forming and other methods from the manufacturing process. Different manufacturing processes form different product appearance structures and performances. To meet the different needs of the market, among them, there are many products manufactured by the stamping welding forming process, especially the demand market in European and American countries is relatively large. [0003] The materials of steel gardening shovels adopting stamping welding forming process are mainly carbon steel and stainless steel. The structure of existing gardening shovels is as follows: Figure 1 to Figur...

AI Technical Summary

Problems solved by technology

[0014] (1) The triangle tie of the pipe pants is the weakest link: because the gardening shovel has certain product appearance and load requirements, in the case of the aforementioned prior art, the triangle tie of the pipe pants does not fit the contact with the shovel plate and needs to Surfacing welding, which not only requires high technical requirements for welders, but also needs to be processed by grinding, sanding and polishing after the whole shovel is welded, so as to make the gardening shovel have a bright appearance, but this will cause damage to the welded parts of the product. Different degrees of wear and tear, and the stress load point of the product during use is just concentrated near the triangular tie, so that once the garden shovel is damaged during use, it often occurs at the triangular tie of the pants, that is, The gusset of the pant is disengaged from the scraper (see Image 6 )

[0015] (2) Difficult processing, low efficiency, and unstable quality: Due to the limitation of product structure and processing equipment in the prior art, it is difficult to use mechanized equipment to carry out effective large-scale production. , Grinding, sanding, polishing and other processes are all manual operations. Not only is the processing difficult and the production efficiency is low, but it is also difficult to accurately detect the wear of the welded road after processing in a low-cost and high-efficiency way, which leads to product quality. In addition, the connection between the trousers and the reinforcing plug is closed and processed. After the trousers are formed, three small sections of reinforcing plugs are welded in. In the triangular tie position and the stressed part of the trousers, the combination of the reinforcing plug and the tube cannot be completely guaranteed. The inner wall of the trousers fits in place, and the force of the reinforcing plug exists at the junction of the sections, and the load strength is poor

[0016] (3) The labor intensity is high, and the environmental pollution is relatively large: because most of the procedures in the prior art can only be processed manually, such as the polishing process, the operator directly presses the workpiece directly on the sand of the polishing grinding machine with manpower The operation is very labor-intensive, and because it is impossible to isolate the workers from the equipment operating surface, the ventilation and environmental protection facilities are ineffective, the operating environment is polluted, and the operating risk factor is high. Workpieces often fly out and hurt people, and the hands are worn. Occupational Pneumoconiosis, hand nerve paralysis, etc. have led to fewer and fewer employees in recent years and low production efficiency, which has always been a difficult processing problem for the entire industry
