Description
Technical Field
The utility model belongs to the technical field of the riveter accessory, especially, relate to an outer tube.
Background
The front end of the riveter has a protective tube, i.e. an outer sleeve in this application, and the existing machining of such tubes uses tubes of equal wall thickness for the manufacturing process. This approach has many drawbacks, such as significant material waste, and inefficient processing. In order to improve the defects, an inventor utilizes forging to process an outer sleeve, the inner part of the outer sleeve is of a solid structure after forging, but a step-shaped shaft body is formed on the outer wall of the outer sleeve, the material cost is saved to a certain extent by the improvement mode, but the improvement space is still available, and secondly, for the existing outer sleeve, the subsequent machining has great problems, for example, the radial deformation is caused by the collision of the tubular product processing method, the clamping is inconvenient, and the final machining and forming of the step-shaped shaft body and the final machining and forming of the tubular product are inconvenient to assemble.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the above-mentioned problem, provide an outer tube that can solve above-mentioned technical problem.
In order to achieve the above purpose, the utility model adopts the following technical proposal:
the outer sleeve comprises a long pipe body, a closed part is arranged at one end of the long pipe body, a large cylinder is connected to the other end of the long pipe body, a conical surface which inclines inwards towards the long pipe body is arranged at one end, far away from the long pipe body, of the large cylinder, an outer hexagonal part is arranged on the outer wall of one end, close to the large cylinder, of the long pipe body, and the long pipe body, the large cylinder and the outer hexagonal part are integrally formed through forging.
In the outer sleeve, the outer hexagonal part is connected with the long pipe body through the connecting inclined plane.
In the outer sleeve, an inner chamfer is arranged at the joint of the long pipe body and the large cylinder.
In the outer tube described above, a tapered hole is provided in the inner surface of the closing portion.
In the outer sleeve, the axis of the long pipe body coincides with the axis of the large cylinder.
In the outer sleeve, the inner wall of the large cylinder is provided with an internal thread.
Compared with the prior art, the outer sleeve has the advantages that:
the investment of the forging material at the early stage is reduced, and the manufacturing cost is greatly reduced.

Fig. 1 is a schematic structural diagram provided by the present invention.
Fig. 2 is a left side view structure diagram provided by the present invention.
In the figure, a long pipe body 1, an inner chamfer 10, a sealing part 2, a large cylinder 3, a conical surface 30, an outer hexagonal part 4 and a connecting inclined surface 40.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1 and 2, the outer sleeve includes a long tube 1, a sealing portion 2 is provided at one end of the long tube 1, and the sealing portion 2 is used for improving radial deformation resistance after forging and preventing deformation due to radial stress caused by the structure of a through hole.
The other end of the long tube body 1 is connected with a large cylinder 3, and the axial lead of the long tube body 1 is superposed with the axial lead of the large cylinder 3. The overlapping improves the precision to prevent subsequent front and back position interference after assembly.
Secondly, the superposition can prevent the eccentricity of the long pipe body 1 caused by the front and back misalignment when the threads on the inner wall of the large cylinder are subsequently processed, and the whole outer sleeve is prevented from being installed into the clamp.
In addition, the length of the long pipe body 1 is longer than that of the large cylinder, the large cylinder is mainly designed to be connected with the rivet gun body, smooth ejection of the internal rivet can be formed through the structure that the outer hexagonal part 4 is connected with the long pipe body 1 through the connecting inclined surface 40, and of course, a hole body is machined in the center of the closed part 2 of the final finished outer sleeve pipe, so that the rivet can be ejected conveniently.
The end of the large cylinder 3 far away from the long tube body 1 is provided with a conical surface 30 which inclines inwards towards the long tube body 1, the outer wall of the end of the long tube body 1 near the large cylinder 3 is provided with an outer hexagonal part 4, and the long tube body 1, the large cylinder 3 and the outer hexagonal part 4 are integrally formed through forging.
Secondly, an inner chamfer 10 is arranged at the joint of the long pipe body 1 and the large cylinder 3. The inner chamfer 10 is directly machined and formed through forging, and in such a way, the subsequent machining chamfer can be reduced, and the production and machining efficiency is invisibly improved.
A tapered hole 20 is provided in the inner surface of the closing portion 2. The tapered hole 20 is also for material input cost saving.
The length of the outer hexagonal part 4 is shorter than the length of the large cylinder 3.
The wall thickness of the long pipe body 1 is smaller than that of the large cylinder 3, and the design can save the input amount of forging materials to a certain extent. And a positioning plane is arranged at one end of the sealing part 2 far away from the long pipe body 1 so as to facilitate subsequent drilling and positioning.
The conical surface 30 forms an angle of 75-85 degrees with the axis of the large cylinder 3, while the inner chamfer 10 is an inclined chamfer and the inner chamfer 10 forms an angle of 45-55 degrees with the axis of the large cylinder 3.
With the design of the inner chamfer 10, it can facilitate forging ejection.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
