Problems solved by technology

However, it is difficult to operate, and requires manual welding, repeated heating forging, and quenching to achieve it. Moreover, the mechanical strength of the welded hoe and the reinforced arched triangular steel plate is obviously worse than that of integral molding, and the appearance and shape are not good. Quality hard to guarantee

Embodiment 1

[0025] Accompanying drawing 1 shows a kind of H316 hoe, comprises hoe board 1 and hoe weng 3, hoe board 1 front end has hoe blade 2, hoe board 1 rear end has the hoe weng 3 that contracts and transitions into one, and the hole of hoe weng 3 forms an arch In the lower square, there is a ridge-shaped tendon 4 at the junction of the hoe Weng 3 and the hoe board 1 .

[0026] Accompanying drawing 3 represents the method step of H316 hoe forming:

[0027] Figure 3A is to determine the weight of the steel billet according to the size of the required workpiece size and cut it into a billet, and heat the billet in a furnace to obtain the shape of the high-temperature billet;

[0028] Fig. 3B shows that the positioning of the lath-shaped high-temperature blank is punched down to the concave hole;

[0029] Fig. 3C shows the slab-shaped high-temperature blank that has been punched with the lower concave hole, and the remaining part is stretched wide by mechanical force to form the requir...

Embodiment 2

[0037] Accompanying drawing 2 shows is a kind of H304 hoe, comprises hoe plate 1 and hoe weng 3, hoe plate 1 front end has hoe blade 2, hoe plate 1 rear end has the hoe weng 3 that shrinks and transitions into one, and the hole of hoe weng 3 forms It is circular, and there is a ridge-shaped tendon 4 at the junction of the hoe Weng 3 and the hoe board 1 .

[0038] The method step of H304 hoe forming is:

[0039] 1. Determine the weight of the steel billet according to the size of the required workpiece size and cut it into a billet, and heat the billet in the furnace to form a high-temperature billet;

[0040] 2. Depending on the shape of the high-temperature blank, choose to directly position and punch the strip-shaped high-temperature blank into the pit, or choose to press it into a strip shape by mechanical forging and then position and punch down the pit;

[0041] 3. After the slab-shaped high-temperature blank has been punched with the lower concave hole, the remaining pa...

Embodiment 3

[0050] This example is a kind of H316 hoe, and structural shape is with embodiment 1.

[0051] Its forming method is to increase the embossing product mark step on the hoe blank in the step F of embodiment 1.

Abstract

The invention discloses a hoe and hoe shaping method in the preparing technical domain of agricultural mechanic tool, which is integral shaped and forged hoe board and hoe clamp, wherein a ridged bar is arranged at the connecting position of hoe board and hoe clamp. The manufacturing flow path comprises the following steps: adding raw materials; heating to make high-temperature blank; locating; flushing a crater pit; extending the breadth through mechanic force; extending the length through mechanic force; making the skirt rim of crater pit display entire round hole shape; cutting residual peripherial material of hoe blank; trimming to form the hoe clamp; pressing the hoe board into arc mechanically; cooling; sharpening the hoe; polishing; painting; drying; obtaining the product.

Description

technical field [0001] The invention relates to a hoe integral forging forming process method. It belongs to the manufacture of agricultural machinery (B21K 19 / 00), die forging, trimming using special dies (B21J 5 / 02·) and piercing of metal blanks (B21J 5 / 10··) in the International Patent Classification (Int.C1). technology field. [0002] The manufacturing method adopted in the present invention can also be used for agricultural implements such as shovels, rakes, and shovels. Background technique [0003] Existing hoes are formed by manual forging for many times. The process is complicated, raw materials are wasted, and the time required is long. The forging method is old and backward, with high technical difficulty and high labor intensity. , and there is no fixed standard specification. Generally, a blacksmith can only produce 20 irons in one working day. The production efficiency is extremely low, the workload is heavy, and the pollution is serious. [0004] Another ...
