After the structure of the oil adding device is adopted, the utility model discloses a reinforce and send a hose is fit for using in more complicated welding environment, also can regard as a certain section in sending a hose to strengthen sending a soft department of easily buckling, and then increase the life who sends a hose, practices thrift the cost when promoting the security.

Description

Wire feeding hose for welding

Technical Field

The utility model relates to the field of welding technique, especially a welding is with sending a hose.

Background

The wire feeding hose is widely applied to the field of welding and mainly used for guiding and protecting welding wires. In the in-service use, often can be buckled into very big angle by misoperation when sending the wire hose, traditional spring send the wire hose when the wide-angle is buckled, the interval of spring is enlargied, and the welding wire is worn out easily from the gap between the spring, has greatly reduced work efficiency, also causes the damage to other spare parts on the welding system easily, and the welding wire is worn out and still very easily causes the incident.

The Chinese patent CN 85100693B discloses a welding wire feeding hose, which is composed of a plurality of small sections of cross sleeves, wherein the sleeves are connected by hinges through connecting sleeves; the rotating shafts of two adjacent hinges are vertical to each other. The rollers are horizontally and vertically arranged in the sleeve in an alternating manner, and the welding wire moves along the formed cavity. The welding cable is divided into a plurality of strands and placed on the outer corner of the sleeve. The corrugated hose with thick and hard outer side and thin and soft inner side is sleeved outside the hose, and protective gas flows through the hose.

Disclosure of Invention

The utility model discloses the technical problem that needs to solve provides a long service life and high welding of security is with sending a hose.

In order to solve the technical problem, the wire feeding hose for welding of the utility model comprises an outer shell and an inner core, wherein the inner core is a Teflon inner core, the outer shell is a braided wire hose, and the Teflon inner core is arranged in the outer shell; and a spring reinforcing layer is arranged on the inner side of the Teflon inner core.

Preferably, the outer side of the shell is wrapped with a heat-shrinkable insulating tube.

Preferably, the joint is fixed at two ends of a wire feeding hose formed by the outer shell and the Teflon inner core.

After the structure of the oil adding device is adopted, the utility model discloses a reinforce and send a hose is fit for using in more complicated welding environment, also can regard as a certain section in sending a hose to strengthen sending a soft department of easily buckling, and then increase the life who sends a hose, practices thrift the cost when promoting the security.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Fig. 1 is a schematic structural view of the wire feeding hose for welding of the present invention.

In the figure: 1 is a thermal shrinkage insulating tube, 2 is a shell, 3 is a Teflon inner core, 4 is a spring reinforcing layer, and 5 is a joint.

Detailed Description

As shown in fig. 1, the welding wire feeding hose of the present invention comprises a housing 2 and an inner core, wherein the inner core is a teflon inner core 3, and the teflon inner core 3 is disposed in the housing 2. The outer side of the shell 2 is wrapped with a thermal shrinkage insulating tube 1, which plays an insulating role and simultaneously protects the structure of the wire feeding hose. Teflon inner core 3 can provide for shell 2 and insulate, still keeps insulating when pyrocondensation insulating tube pipe 1 breaks, and Teflon inner core 3 can not produce the clearance when taking place to buckle simultaneously, can prevent effectively that the welding wire from wearing out, guarantees to send a hose normal work. The shell 2 is for weaving the wire hose, and the anti ability of buckling of spring of this kind of structure is strong, can effectively reduce the angle of buckling when sending a hose atress, increases the smoothness nature of sending a silk, and it is less to weave the gap that the wire hose produced when taking place to buckle again, can prevent effectively that the welding wire from wearing out.

As shown in fig. 1, 3 inboards of teflon inner core are provided with spring enhancement layer 4, spring enhancement layer 4 is the close wound spring structure with thin spring steel wire, the spring enhancement layer is in order to strengthen the teflon inner core, reduce the deformation of teflon inner core hole when the bending, guarantee the stability in aperture, improve the unobstructed degree of sending a silk, use thin spring steel wire, it is as level and smooth as far as possible in order to let spring enhancement layer inner wall, there is teflon's coating film on spring enhancement layer surface simultaneously, make the welding wire unobstructed when wherein passing through more.

And joints 5 are fixed at two ends of a wire feeding hose formed by the shell 2 and the Teflon inner core 3, one side of each joint 5 is fastened on a spring shell of the wire feeding hose, and the other end of each joint is provided with threads and can be connected to other wire feeding hoses or equipment through matched joints.

Although specific embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are merely examples and that many changes and modifications may be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims.
