Problems solved by technology

[0004] Therefore, in view of the above-mentioned problems, the present invention proposes a production process of rice transplanter needles, which solves the problem that the existing rice transplanter needles have poor wear resistance and impact resistance, are easily damaged, and will inevitably hit stones and other sundries when working in paddy fields. Therefore, it is necessary for the transplanting needle to have relatively strong wear resistance and impact resistance. On the other hand, the structure is complex, the production, assembly and maintenance are more cumbersome and the technical problems of easy damage to the rice seedlings

Embodiment Construction

[0018] The present invention will be further described in conjunction with specific embodiments.

[0019] The present embodiment provides a kind of production technology of rice transplanter needle, and its steps comprise:

[0020] 1) preparing metal powder;

[0021] 2) Mix the various metal powders required in a certain proportion and make them homogeneous;

[0022] 3) Press the uniform metal powder into the mold, and make the density of the preform reach 6.5-6.6g / cm3, and send it into the sintering furnace for heating;

[0023] 4) demoulding, cooling at room temperature;

[0024] 5) The obtained metal ingot is cut, and the cut metal block is put into a cold forging die or a forming die for forging and stamping.

[0025] The preparation of metal powder in the step 1 can adopt two methods of reduction method and mechanical method.

[0026] Mixing in the step 2 uses a stirring device to stir the above powder in a closed mixing chamber at room temperature for 60-80 minutes. ...

Abstract

The invention discloses a production process of a seedling needle of a rice transplanter, and improves the situations that the conventional seedling needle is poor in wear resistance and impact resistance and easy to damage, and sundries such as stones are inevitably hit when the conventional seedling needle works in a paddy field, a seedling needle having relatively strong wear resistance and impact resistance is required, and the conventional seedling needle is complicated in structure and relatively tedious in production, assembly and maintenance. Raw materials are processed in a powder metallurgy mode, a obtained blank is matched with the cold forging and stamping production mode, the wear resistance and the impact resistance of the seedling needle are greatly improved, meanwhile, the cold forging and stamping production mode is adopted for production, the production efficiency of the seedling needle is greatly improved, and the production cost and the production difficulty are reduced.

Description

technical field [0001] The invention relates to the field of powder metallurgy, in particular to a production process of seedling needles for rice transplanters. Background technique [0002] Powder metallurgy is a process technology for producing metal or using metal powder (or a mixture of metal powder and non-metal powder) as raw material, after forming and sintering, to manufacture metal materials, composite materials and various types of products. Due to the advantages of powder metallurgy technology, it has become the key to solve the problems of new materials and plays a pivotal role in the development of new materials. The rice transplanter is a planting machine for planting rice seedlings in paddy fields to improve the work efficiency and quality of transplanting, realize reasonable dense planting, and facilitate the mechanization of subsequent operations. The working process of the rice transplanter is different due to different structures, but the basic process i...
