Problems solved by technology

Known guide wheels are generally made by casting. Because the hardness and compactness of the chain in frictional contact with the guide wheel are relatively large, the two shoulders of the guide wheel in frictional contact with the chain for a long time are severely worn, and even voids inside the guide wheel appear. The phenomenon that the side wall between the cavity and the outside is worn through, which leads to the failure of the guide wheel, which not only increases the maintenance cost of the equipment, but also wastes a lot of precious time to replace the guide wheel, which is the disadvantage of the known guide wheel

Embodiment Construction

[0024] Referring to Fig. 1 to Fig. 5, the embodiment discloses a production method of a guide wheel, comprising the following steps:

[0025] 1), material preparation: cut a quantitative 40Mn2 round steel billet and place it in a heating furnace to heat it to about 1200°C, then place it on a molding die of a 6000-ton friction press for forging to obtain the side plate 1, and then place it on the side plate 1. A shaft hole 11 is punched out in the radial middle part of the disk 1, and the mold cavity of the forming mold corresponds to the shape of one side of the axial direction of the guide wheel. In other words, the known guide wheel is cut in half along the axial direction, and the described The mold cavity formed by the male mold and the female mold of the forming mold just corresponds to the half guide wheel after cutting, and the shaft hole 11 is punched in the radial middle of the side plate 1 for the convenience of subsequent steps, not for an essential process step;

Abstract

The present invention provides a preparing method of lead wheel, including following steps: cutting quantitative steel billet and heating to 1100-1300 centidegree, then forging to a side disk of half-lead whell structure, the center of the two disks which is set opposite, setting a fixed hole after welding, a fixed axle welded in the fixed hole and processing thermal refining, a axle hole and a floating ring groove setting in the fixed hole, the working surface of workpiece after being fine finished quenching in medium frequency, finally, a lead wheel is obtained by assembly. Beading part of the lead wheel prepared in this way has a high intensity, high compactness and a longer life which is 2 times than the lead wheel of the known casing method.

Description

technical field [0001] The invention relates to a method for producing a guide wheel. The prepared guide wheel is used for guiding chains in crawler excavators, tanks and other equipment. Background technique [0002] Known crawler excavators or tanks generally include a chassis and track shoes, chains, rollers, guide wheels, supporting sprockets, gearwheels, etc. on the chassis. The big gear drives the track shoes to rotate through the chain. The heavy wheels are used to support the weight of the equipment, and the guide wheels are used to guide the walking of the chain. The known excavator has been widely used in infrastructure, water conservancy engineering, road laying and other fields. Known guide wheels are generally made by casting. Because the hardness and compactness of the chain in frictional contact with the guide wheel are relatively large, the two shoulders of the guide wheel in frictional contact with the chain for a long time are severely worn, and even voids...
