Problems solved by technology

[0002] Bucket teeth and gear holders on excavators are indispensable parts during operation. The requirements for these parts are very high, and the demand is also large. Generally, manufacturers use casting or semi-mechanical and semi-manual forging for processing. When processing by casting, although the output can be guaranteed, the product quality cannot be guaranteed, especially the strength of the product. When processing in a semi-mechanical and semi-manual way, although the strength of the product can be guaranteed, the production efficiency is low, and the product shape and the accuracy cannot meet the requirements

Embodiment Construction

[0029] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and embodiments. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0030] A method for manufacturing excavator bucket teeth, comprising the following steps:

[0031] Step 1: Since the hot-rolled bar from the rolling mill has a variation range of about 4% in cross-sectional area, it is actually irregular. It is not enough to control the weight of the billet only by the length of the length. Often the obtained billet If the quality is too heavy or too light, it will affect the forging of subsequent products. In order to ensure that the product quality specifications are consistent, the bar is placed on an automatic weighing device for weighing, and the mass and volume per unit length are calculated.

Abstract

The invention discloses a manufacturing method of excavator bucket teeth. The method comprises the following steps that bar materials are weighed; the bar materials are heated; the heated bar materials are sent into a hot shearing machine at forging temperature for shearing blanking; the shearing length is automatically adjusted according to the calculated mass and size of per unit length, and it is guaranteed that sheared small materials are uniform in weight; forging forming, polishing and cleaning, quenching after forging, tempering and inspecting and packing are sequentially conducted. Therefore, the production efficiency is improved, the production cost is reduced, and meanwhile the product quality is guaranteed.

Description

technical field [0001] The invention relates to a method for manufacturing excavator bucket teeth. Background technique [0002] Bucket teeth and gear holders on excavators are indispensable parts during operation. The requirements for these parts are very high, and the demand is also large. Generally, manufacturers use casting or semi-mechanical and semi-manual forging for processing. When processing by casting, although the output can be guaranteed, the product quality cannot be guaranteed, especially the strength of the product. When processing in a semi-mechanical and semi-manual way, although the strength of the product can be guaranteed, the production efficiency is low, and the product shape And the accuracy can not meet the requirements. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art and provide a method for manufacturing excavator bucket teeth with high production efficiency and good product qua...
