Problems solved by technology

[0003] One is formed by repeated forging and pressing of raw materials with a thickness greater than that of the finished product; the process has many shortcomings and deficiencies found in the actual production process: (1) Low production efficiency and long processing cycle
(2) High production cost and high cost
Due to the overall heating of the billet and repeated forging, it needs to consume more coal for heating, which is not conducive to the national energy-saving and emission-reduction policy.
⑶ The appearance quality is poor, and the users are not satisfied
Its technology has also been found to have many shortcomings and deficiencies in the actual production process: (1) Low production efficiency and long processing cycle
(2) High production cost and high cost
⑶ Due to welding first and then forging, interlayers will be formed after forging, which will easily cause cracking tendency during quenching, and the quality of plow and shovel cannot be effectively guaranteed
⑷The appearance quality is poor, and the users are not satisfied
The plow shovel produced by this process has also been found to have many shortcomings and deficiencies in the actual production process: (1) special equipment and technology are required, and the investment in equipment is huge
(2) High production cost and high cost

Embodiment Construction

[0055] Such as Figure 5-Figure 7 Shown is a structural schematic diagram of the roughening mold used in the method for roughening the plow shovel blank of the agricultural plow tool in order to form the reinforcing rib according to the present invention.

[0056] Depend on Figure 5-Figure 7 It can be seen that the pier rough die of the present invention includes: a lower die set connected to the fixed worktable of the forging press, which has a fixed lower die 8 and a movable lower die 14 arranged side by side, and between the fixed lower die 8 and the movable lower die 14 Form a positioning station hole for positioning the non-pier thick part 2 of the plow shovel blank 1 (that is, the part used to form the shovel body 4'); the upper die set connected with the movable worktable of the forging press has a An upper mold 6 that is movable up and down for contacting with the plow shovel blank 1 to be thickened so that it is thickened, and the upper mold is aligned with the posi...

Abstract

The invention discloses a method used for manufacturing ploughing blade reinforcing ribs of agricultural ploughs. The method comprises the steps of carrying out blanking on steel sheets to form ploughing blade blanks with to-be-upset parts on the edges; heating the to-be-upset parts, on the edges, of the ploughing blade blanks; placing the ploughing blade blanks partially heated into upsetting dies; carrying out upsetting on the heated to-be-upset parts, placed into the upsetting dies, of the ploughing blade blanks through a forging machine so as to thicken the to-be-upset parts; forging and pressing the thickened to-be-upset parts of the ploughing blade blanks so as to form the reinforcing ribs on the ploughing blade blanks. According to the invention, the upsetting dies are simple in structure and convenient to use, blade bodies and the reinforcing ribs of ploughing blade products machined through the upsetting dies can be formed through one steel sheet, machined ploughing blades are high in strength and good in durability, the reinforcing ribs of the ploughing blades are prevented from being separated from the blade bodies, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a method for manufacturing parts of an agricultural plow, in particular to a method for manufacturing a reinforcing rib of a plow shovel head of a part of an agricultural plow. Background technique [0002] At present, there are mainly three manufacturing and processing methods for the flange part (reinforcing rib) of the plow shovel head of the agricultural plow tool parts. [0003] One is formed by repeatedly forging and pressing a raw material with a thickness greater than that of the finished product through a hot forging die; the process has been found to have many shortcomings and deficiencies in the actual production process: (1) Low production efficiency and long processing cycle. (2) The production cost is large and the cost is high. Because the billet is heated as a whole and formed by repeated forging, it needs to consume more coal for heating, which is also not conducive to the country's energy-saving and emission-...
