Embodiment Construction

[0021] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0022] A final forming process of a steel agricultural hoe blank, comprising the following steps:

[0023] Step 1, making the pouring mold; combining figure 1 , figure 2 As shown, the pouring mold is used for forming the sickle, and consists of a steel upper mold 1 and a steel lower mold 2. The lower surface of the steel upper mold 1 is a plane, the steel upper mold 1 is provided with an upper mold cooling water channel 1c, the steel upper mold 1 is provided with an upper mold water inlet pipe 1a and an upper mold outlet pipe 1b, and the upper mold enters The water pipe 1a, the upper mold cooling water channel 1c and the upper mold outlet pipe 1b are connected in sequence to cool down the steel upper mold 1 and facilitate rapid cooling of the molten steel in the pouring mold. The upper surface of the steel lower mold 2 is provided with a cavity 2c matchin...

Abstract

The invention discloses a final molding process of an agricultural steel hoe blank. The final molding process comprises the following steps: manufacturing a casting die comprising an upper steel die and a lower steel die; filling cooling water into the casting die; heating steel materials to form molten steel; casting; enabling the upper steel die to move downwards under the action of a hydraulic drive system or a pneumatic drive system until the upper steel die is buckled with the lower steel die; cooling the molded die, and the like. The molded agricultural hoe has a smooth surface and a, beautiful appearance without any air pore, so that the quality of the hoe is high. The hoe is made of raw materials with stable and abrasion-proof performance, so that the hoe has a long service life. In addition, the raw material waste is avoided during the molding process, and the material utilization ratio reaches 100%, so that the manufacturing cost is saved. The molding process has the advantages of simplicity in molding, easiness in implementation and small labor intensity, thereby lowering the manufacturing cost further.

Description

technical field [0001] The invention belongs to the field of processing technology of agricultural hoes, and in particular relates to an ultimate forming process of agricultural hoes, including sickles, hoes, plowshares and the like. Background technique [0002] In order to ensure the durability of agricultural hoes, traditionally processed agricultural hoes are usually forged. Forged agricultural hoes, metal materials have uniform carbide structure, fine grains, high hardness, good toughness, wear resistance, and better impact resistance. They are very popular among consumers, but the processing process is complicated. , Time-consuming and labor-intensive, high cost, serious waste of materials, low utilization rate of raw materials and other defects. Contents of the invention [0003] The object of the present invention is to provide an ultimate forming process of agricultural hoes, the manufactured hoes are not only wear-resistant and have a long service life, but also...
