Problems solved by technology

Now the tensioner shells used on agricultural vehicles are all made of cast iron, which requires complex casting processes and supporting facilities. After casting, complex machining processes are required, and the machining workload is large, so the cost is high; Due to its brittleness, the tensioner shell is easily damaged, which increases the maintenance cost

Embodiment Construction

[0010] Taking the shell of the tensioner wheel of the agricultural tricycle as an example, the processing steps are as follows:

[0011] Choose a seamless steel pipe with a diameter of 45-55MM and cut it according to the required length. Then, put the cut semi-finished steel pipe vertically on the punching machine for processing, and form the two ends of the steel pipe with flanging, and the flanging height is 0.5CM; Then use a punching machine to expand the hole, and then use a lathe to further process the inner holes at both ends, so that the inner diameter of the tensioner housing matches the outer diameter of the bearing.

[0012] In this process, other steps such as deburring, car chamfering and other processes are the same as the prior art.

Abstract

The invention is farm car tensed wheel shell processing craft, relating to processing method. The steps are; selecting steel pipe, and cutting the pipe according to the length demanded; then, the cut semi finished articles steel pipe is processed on the punching machine, forms the outwards edges of the steel pipe, the height is 0.3-1cm; then carries on process to the internal apertures at two ends through punching bed or lathe, makes the internal radius of the shell engaged with the external radius of the bearing. The invention is simple and the cost is low.

Description

Technical field [0001] The invention relates to a machining process method, in particular to a processing process for a tensioner shell of an agricultural vehicle arranged between an engine pulley and a rear axle pulley for tensioning a V-belt. technical background [0002] The agricultural vehicle is provided with a tensioner pulley between the engine pulley and the rear axle pulley, which is in contact with the V-belt and is used to adjust the tension of the V-belt. Now the tensioner shells used on agricultural vehicles are all made of cast iron, which requires complex casting processes and supporting facilities. After casting, complex machining processes are required, and the machining workload is large, so the cost is high; Due to its brittleness, the tensioner shell is easily damaged, which increases the maintenance cost. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned existing technology,...
