Stamping die set for harvester picker jaws

Abstract

The invention discloses a stamping die set of a harvester picker jaw. The stamping die set is composed of a positioning hole stamping unit, a notch stamping unit, a first bending stamping unit and a second bending stamping unit. The first bending stamping unit comprises a bending stamping block and a bending stamping base, wherein the bending stamping block and the bending stamping base are matched. The second bending stamping unit comprises a forming stamping block and a forming stamping base, the bearing surface of the forming stamping base is matched with the stamping surface of the bending stamping block, the bearing surface of the forming stamping base is provided with a groove matched with a stamping head of the forming stamping block, and a jaw machined part to be formed does not interfere with the forming stamping block when the second bending stamping unit is in a stamping state. By the application of the die set, the first bending stamping unit and the second bending stamping unit are adopted to integrally bend the jaw machined part step by step, the bending angle is accurate, the bending surface of the jaw is smooth and standard after the jaw is bent, the jaw is not prone to being bent or broken in the machining process, the forming percent of pass of the jaw machined part is increased, and the quality of the jaw is improved.

Description

technical field [0001] The invention relates to a die set, in particular to a stamping die set for a picker claw of a harvester. Background technique [0002] The Harvester was invented by Cyrus McCormick. Harvester It is an integrated machine for harvesting crops. Harvesting, threshing and concentrating the grains into the storage bin at one time, and then transporting the grains to the transport vehicle through the conveyor belt. Manual harvesting can also be used to spread the stalks of rice, wheat and other crops in the field, and then use grain harvesting machinery to pick up and threshing. Crop harvesting machinery for harvesting grains and stalks of cereal crops such as rice and wheat. Including harvesters, windrowers, balers, grain combines and grain threshers, etc. Grain harvesting machinery is developed on the basis of various harvesting and threshing tools. [0003] Today's harvesters have a larger and wider fuselage, so the loaded picker claws are also wider...

AI Technical Summary

Problems solved by technology

[0003] Today's harvesters have a larger and wider fuselage, so the loaded picker claws are also wider, and the wider picker claws are inconvenient for bending, often resulting in insufficient bending angles or The phenomenon of uneven bending, and in the process of bending, the problem of bending damage often occurs
