[0002] When ore is mined, it is necessary to use a crushing and screening machine to crush and screen the ore. Due to the serious wear of the tooth plate on the crushing and screening machine and the tooth tips on the tooth plate during crushing, the ore processing capacity is reduced, and the tooth plate is forced to be replaced.
Due to the frequent replacement cycle of the tooth plate and the large consumption, the production efficiency of the enterprise is slow, which seriously affects the production efficiency

Embodiment Construction
[0010] Such as figure 1 As shown, a method for repairing the wear of the tooth plate 1 and the teeth of a MMD14 tooth crusher, the repair method includes the following steps:
[0011] (1) Select the tooth plate 1 and the tooth tip 2 on the tooth plate 1 after being worn out and scrapped on the crusher, and set them aside;
[0012] (2) After cutting the reusable tooth tip 2 that meets the requirements from the severely worn tooth plate 1, the tooth tip 2 is welded to the tooth plate 1 by the inlay repair welding process, so that the welded tooth plate 1 The size of tooth tip 2 conforms to the height and length required by the crusher;
[0013] The inlaid repair welding process is as follows: cut a V-shaped groove at the edge of the butt joint between the tooth tip 2 and the tooth plate 1, and use arc welding or flat welding to surfacing welding with short arc welding at the bottom of the welding joint. The model is The J507 welding rod is used as a primer to form a welding tr...

The invention relates to an abrasion repair method for a toothed plate and teeth of an MMD14-tooth crusher. The abrasion repair method comprises the following steps that, (1) the worn and scrapped toothed plate and tooth tops on the toothed plate of the crusher are selected for standby application; and (2) after the reusable tooth tops with required sizes are cut down from the seriously worn toothed plate, the tooth tops are welded on the toothed plate by using an inlaying reparation welding procedure, and the sizes of the welded toothed plate and tooth tops meet the height and length requiredby the crusher. The inlaying reparation welding procedure comprises the following steps that a V-shaped groove is cut on the abutting edge of the tooth tops and the toothed plate, a welding rod of the model J507 is first used at the bottom of a soldering opening by using arc welding or downhand welding in a manner of short arc welding built-up welding to form a welding transition layer; and a welding rod of the model A108 is used for welding in a filling mode by three layers. The toothed plate and tooth tops of the crusher are repaired, so that the production cost of enterprises is reduced, and the resource utilization is increased.
Description
technical field [0001] The invention belongs to the field of mining equipment, and in particular relates to a method for repairing wear of tooth plates and teeth of an MMD14-tooth crusher. Background technique [0002] When ore is mined, it is necessary to use a crushing and screening machine to crush and screen the ore.
