Abstract
The invention relates to the field of bucket teeth, in particular to a bucket tooth assembly, which comprises a bucket tooth and a tooth holder and is characterized in that the bucket tooth comprises a tooth tip and a tooth root, wherein the tooth tip and the tooth root are integrally formed, the tooth holder comprises a holder body and an inner cavity, the inner cavity of the tooth holder is matched with the tooth root and is connected with the tooth root through a pin, and the tooth root is conical.
Description
Technical Field
The invention relates to the field of bucket teeth, in particular to a bucket tooth assembly.
Background
According to patent numbers 201120390837.3, 201620300886.6, 201610546742.3 and 201920843658.7, the traditional bucket tooth components are that a bucket tooth and a tooth seat head are fixedly connected through a pin component, the bucket tooth comprises a tooth tip and an inner cavity, the tooth seat comprises a seat body and a part embedded into the inner cavity of the bucket tooth, the bucket tooth in the traditional technology is cast, but the cast strength is not good, so that the existing bucket tooth is in a forged form, but the inner cavity is arranged in the bucket tooth, so that the rejection rate of the forged bucket tooth is high; in the process of using the bucket tooth in practice, the bucket tooth rather than the tooth holder needs to be replaced frequently, and the tooth holder can be completely cast instead of forged because the bucket tooth is in direct contact with the action surface.
Disclosure of Invention
In order to solve the problems, the invention provides a bucket tooth assembly and a manufacturing process thereof.
This kind of bucket tooth subassembly, including bucket tooth and toothholder, its characterized in that, the bucket tooth includes prong and tooth root, prong and tooth root integrated into one piece, and the toothholder includes pedestal and inner chamber, and the inner chamber of toothholder is joined in marriage and is passed through pin connection with the tooth root of bucket tooth.
Further, the tooth root is tapered.
The bucket tooth has the advantages that the thinking fixed mode of the traditional technology is changed, and the bucket tooth with high qualification rate can be obtained by the same process through changing the structures of the bucket tooth and the tooth holder.
Drawings
FIG. 1 is a schematic view of a bucket tooth structure
FIG. 2 is a schematic view of a bucket tooth seat
In fig. 1 and 2, 1, a bucket tooth, 2, a tooth holder, 1.1, a tooth tip, 1.2, a tooth root, 1.1 and 1.2 of the tooth tip and the tooth root are integrally formed, 2.1, a holder body, 2.2 and an inner cavity.
Detailed Description
This kind of bucket tooth subassembly, including bucket tooth 1 and toothholder 2, its characterized in that, bucket tooth 1 includes prong 1.1 and tooth root 1.2, prong 1.1 and tooth root 1.2 integrated into one piece, and toothholder 2 includes pedestal 2.1 and inner chamber 2.2, and inner chamber 2.2 of toothholder 2 cooperates and passes through pin connection with the tooth root 1.2 of bucket tooth 1, and tooth root 1.2 is the toper.
Taking round bar materials such as phi 60 x 230, burning the materials for 10s by an intermediate frequency furnace to 1050-1150 ℃, forging and pressing 1000 bucket teeth and 1000 traditional bucket teeth by a forging press, wherein the counting result is as shown in the following table 1 when insufficient forging forming or crease, fatigue line or crack occurs.
Table 1.
| Unqualified (piece) | Qualified (spare) | |
| Bucket tooth of the |
1 | 999 |
| Traditional bucket tooth | 250 | 750 |
The number of unqualified pieces 250 in the traditional bucket tooth comprises 60 pieces with insufficient forging forming, 113 pieces with creases and 77 pieces with fatigue marks.
In conclusion, the forging mode is adopted, the qualification rate of the bucket tooth of the traditional structure is 75%, and the qualification rate of the bucket tooth of the invention is 99.9%.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications made by the present invention in the equivalent structure or directly or indirectly applied to other related technical fields are included in the scope of the present invention.
Claims (2)
1. The utility model provides a bucket tooth subassembly, includes bucket tooth and toothholder, its characterized in that, the bucket tooth includes prong and tooth root, prong and tooth root integrated into one piece, and the toothholder includes pedestal and inner chamber, and the inner chamber and the tooth root of toothholder cooperate and pass through pin junction.
2. The bucket tooth assembly of claim 1, wherein the tooth root is tapered.
