Abstract

The utility model discloses a small bent-angle copper nose. The copper nose includes a wire compartment and a nose wing. The utility model is characterized in that the wire compartment and the nose wing are fixedly connected, and one end face of the nose wing is tangent to the outer circular edge of the wire compartment. The bottom is provided with a cut hole, which is used for stamping and shaping of the nose wing and reducing the thickness of the connection buffer structure between the nose wing and the wire compartment; this scheme improves the processing technology structure compared to the prior art, so that the transition part between the wire compartment and the nose wing is made. It basically does not exist. Secondly, the nose wing of this product is tangent to the edge of the wire compartment, which makes the copper nose produced by this solution more stable when fixed to the equipment, and solves the waste of resources in the connection part of the current copper nose processing. Compared with the existing copper nose The nose greatly saves materials, reduces the volume, and reduces production costs and transportation costs.

Small-size bent angle copper nose

Technical Field

The utility model belongs to the technical field of binding post technique and specifically relates to a small-size bent angle copper nose.

Background

The copper nose is also called wire nose, copper wire connecting nose, copper pipe nose, wiring terminal and the like, and is an important connecting piece for connecting wires and cables to electrical equipment.

In the past, when a copper nose product is produced, the efficiency is low, the cost is high, the occupied labor is large, particularly, the existing copper nose is usually bent by a copper pipe, but the bending deformation is irregular due to various reasons, the products produced in batches have the defects of unstable difference and quality, and the concept of standardized management of the produced products is not met.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a small-size bent angle copper nose, it makes the copper nose of making through this scheme preparation relatively current copper nose through having improved the preparation method, and is more miniaturized, especially has eliminated the transition part between line storehouse and the nose wing, has practiced thrift copper nose volume itself and material cost greatly.

To the above-mentioned, the utility model discloses a small-size bent angle copper nose, including line storehouse and nose wing, its characterized in that, line storehouse and nose wing fixed connection set up, a side end face of nose wing is tangent with the outer disc limit in line storehouse, just the relative line storehouse of nose wing has the turning setting, the bottom in line storehouse is provided with the cut hole, the cut hole is used for the punching press of nose wing to finalize the design and reduces the thickness of the buffer structure that is connected of nose wing and line storehouse.

As a further arrangement of the scheme, the material of the connecting buffer part of the wire bin and the nose wing is provided with an inclined plane angle.

Has the advantages that: this scheme is through processing integration shaping to the pipe for prior art, through improving processing technology structure, make transition part between line storehouse and the alar basically not exist, secondly the alar edge tangent with line storehouse of this product, make the copper nose of this scheme production more stable when being fixed in equipment, it has solved current copper nose processing through simple incision punching press and has had the wasting of resources of connecting portion, the difficult fragile scheduling problem of punching press, for current copper nose, the material has been saved greatly and the volume has been reduced, and the production cost is lightened, and the transportation cost.

Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflicting with each other.

The small-sized bent-angle copper nose shown in fig. 1-2 comprises a line bin 1 and a nose wing 2, and is characterized in that the line bin 1 and the nose wing 2 are fixedly connected and arranged, one side end face of the nose wing 2 is tangent to the outer circular edge of the line bin 1, the nose wing 2 is arranged at the corner of the line bin 1, a cutting hole 3 is formed in the bottom of the line bin 1, and the cutting hole 3 is used for punching and shaping the nose wing 2 and reducing the thickness of a connection buffer structure of the nose wing 2 and the line bin 1.

As a further arrangement of the above solution, the material of the connecting buffer part of the string cabin 1 and the nose wing 2 is provided with an inclined angle.

A manufacturing method of a small-sized bent-angle copper nose is characterized by comprising the following steps: the method comprises the following steps:

1) preparing a tubular copper material as a raw material of a copper nose, and treating the surface of a copper pipe;

2) placing the prepared copper pipe on a bending die, and starting the die to bend the copper pipe;

3) after the bent pipe is machined, taking out the bent pipe, drawing a notch line on the copper pipe according to the size of a design drawing, and performing notch machining along the notch line through a cutting device;

4) after the notch is machined, taking down the bent pipe and placing the bent pipe into an upper layer die cavity of a double-layer stamping die, and starting a stamping machine to stamp an upper die along the notch position to form a nose wing 2;

5) after the nasal wing 2 is punched, lifting an ejector rod of a punching machine, taking the bent pipe with the nasal wing 2 out of the upper layer die cavity, putting the bent pipe into the lower layer die cavity, starting the punching machine again, and cutting off the bolt holes 4 for fixing the nasal wing 2 and redundant materials on the periphery through a middle die of the double-layer punching die;

6) and taking out the workpiece after the secondary stamping is finished, and carrying out surface treatment to obtain the complete copper nose.
