Abstract
The utility model discloses a socket spanner with a reinforced head part, comprising a socket body and a metal lining at a head part. The socket body is formed in a way that a steel tube is directly sheathed on a flaring of a stamping head part, and then chamfering is carried out. The metal lining at the head part is formed in a way that the steel tube is directly sheathed with a two-stamping flanging, the inner diameter of the socket body is more than the outer diameter of the metal lining at head part, the metal lining at the head part is arranged in the socket body for connection, a groove is formed at the connecting part of the metal lining at the head part and the socket body, the socket body and the metal lining at the head part are welded together by the groove, and then turning polishing treatment is carried out on the surface welding part, so as to enable the surface to be smooth, and finally, internal and external hexagonal molds are adopted to carry out stamping formation. The socket spanner has the advantages that the torque force is reinforced and the spanner is durable and the like.
Description
Technical field
The utility model relates to hardware ﹠ tools, particularly a kind of head reinforcing sleeve barrel spanner.
Background technology
In order to tighten or to unscrew the nut that counterbore is arranged, the loose especially nut that unloads or tighten on automobile and the truck tyre adopts box spanner usually, generally adopt the box spanner of the direct hexagonal forming of a kind of steel pipe in the market, this class box spanner adopts the single wall moulding, torsion is on the low side, and be not durable, run into some and get rusty and often can not use during high-intensity nut.
The utility model content
In order to solve above-mentioned prior art problem, the purpose of this utility model is to provide a kind of head reinforcing sleeve barrel spanner, it have torsion strong, durable in use, save material, alleviate advantages such as instrument weight.
A kind of head reinforcing sleeve of the utility model barrel spanner to achieve these goals, comprise sleeve body, the head metal inner lining, described sleeve body adopts steel pipe directly to overlap punching press head enlarging moulding, chamfering then, described head metal inner lining adopts steel pipe directly to overlap the moulding of twice punching press flange, and the internal diameter of sleeve body is greater than the external diameter of head metal inner lining, the head metal inner lining packed into its two body is connected in the sleeve body, form groove at two body connecting portions, again sleeve body and head metal inner lining are welded together along the groove position, again surface soldered is partly carried out the turning polishing, make its smooth surface, outer-hexagonal mould punch forming in adopting at last.
The utility model is faced the wall and meditated Wrench head work and is thickeied increasing because Wrench head adds metal inner lining, has strengthened torsion, makes spanner durable in use, and has alleviated the weight of instrument.
The effect that the utility model is useful is: torsion reinforcement, durable in use.
