Abstract
A kind of special copper pipe for making private cable joint, comprise the copper pipe that has cylindrical outer wall, be provided with three grooves in the inwall of copper pipe, the bearing of trend of any groove is all parallel to the axis of copper pipe, and three grooves are uniformly distributed along the inner periphery of copper pipe.The section configuration of any groove is all rectangular.Article three, groove is extruded to add at copper pipe and is obtained man-hour.Adopt special copper pipe of the present utility model as female pipe to process private cable joint time, first with the length of three fork pin be the axial actual cut of lathe tool displacement, deduct the numerical value of degree of depth gained of groove with wall thickness for radial cutting amount, turning is carried out to the cylindrical of female pipe, when tube reducing is herein to the footpath, the end of groove, three fork pin are naturally shaping.The utility model simplifies the processing technology of cable joint, and the whole course of processing only needs clamped one time, and be convenient to realize automatic numerical control and produce, production efficiency can increase substantially, and the quality of product has had reliable guarantee.
Description
Technical field:
The utility model relates to electricity field, particularly relates to cable Connection Element, particularly a kind of special copper pipe for making private cable joint.
Background technology:
Partial cables needs to arrange copper pipe joint in its end.Wherein, copper pipe joint needs to arrange an external screw thread at the rear portion of the copper pipe of cylindrical tube, arranges the body of a less external diameter, and in the tube wall of the body of less external diameter, arrange three be parallel to axial groove in front portion, to form three fork pin in copper pipe front portion, be convenient to be connected with electrical equipment terminal.In prior art, this copper pipe joint adopts common heavy wall copper pipe for female pipe.Female pipe obtains suitable length through cutting blanking, and then the cylindrical of turning front portion and the external screw thread at rear portion, finally carry out calibration groove milling in front portion.Common heavy wall copper pipe is utilized to produce this joint, need through multiple clamping, especially more difficult to the Milling Process of three grooves, the precision of clamping, dynamics are difficult to control, dynamics crosses conference makes workpiece deformation, dynamics too small, workpiece can be shaken when Xiyanping injection produces, and affects stability and the dimensional accuracy of Product processing, and makes product rejection
Summary of the invention:
The purpose of this utility model is to provide a kind of special copper pipe for making private cable joint, and the described this special copper pipe for making private cable joint will solve in prior art and be difficult to process from common heavy wall copper pipe the technical problem obtaining the cable joint with three axial grooves.
This special copper pipe for making private cable joint of the present utility model, comprise the copper pipe that has cylindrical outer wall, wherein, three grooves are provided with in the inwall of described copper pipe, the bearing of trend of the groove described in any is all parallel to the axis of copper pipe, and three grooves are uniformly distributed along the inner periphery of copper pipe.
Further, the section configuration of any groove is all rectangular.
Operation principle of the present utility model is: special copper pipe of the present utility model obtains by extruding processing.When copper pipe extrusion molding, inwall forms three grooves.Adopt special copper pipe of the present utility model as female pipe to process private cable joint time, only need on lathe once clamping, first with the length of three fork pin be the axial actual cut of lathe tool displacement, deduct the numerical value of degree of depth gained of groove with wall thickness of the present utility model for radial cutting amount, turning is carried out to the cylindrical of female pipe, when tube reducing is herein to the footpath, the end of groove, three fork pin are naturally shaping.After processing three fork pin, stride across interlude, turning goes out the external screw thread of the other end, and the length of workpiece by regulation is cut off.
The utility model is compared with prior art, and its effect is actively with obvious.The utility model is provided with three grooves in the inwall of copper pipe, and the bearing of trend of the groove described in any is all parallel to the axis of copper pipe, and three grooves are uniformly distributed along the inner periphery of copper pipe.Simplify the processing technology of cable joint, the whole course of processing only needs clamped one time, and be convenient to realize automatic numerical control and produce, production efficiency can increase substantially, and the quality of product has had reliable guarantee.

Embodiment:
Embodiment 1:
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, special copper pipe for making private cable joint of the present utility model, comprise the copper pipe 1 that has cylindrical outer wall, wherein, three grooves 2 are provided with in the inwall of described copper pipe 1, the bearing of trend of the groove 2 described in any is all parallel to the axis of copper pipe 1, and three grooves 2 are uniformly distributed along the inner periphery of copper pipe 1.
Further, the section configuration of any groove 2 is all rectangular.
The operation principle of the present embodiment is: special copper pipe 1 obtains by extruding processing.When copper pipe 1 extrusion molding, inwall forms three grooves 2.When adopting special copper pipe 1 to process private cable joint as female pipe, only need on lathe once clamping, first with the length of three fork pin 3 be the axial actual cut of lathe tool displacement, deduct the numerical value of degree of depth gained of groove with wall thickness of the present utility model for radial cutting amount, turning is carried out to the cylindrical of female pipe, when tube reducing is herein to the footpath, the end of groove 2, three fork pin 3 are naturally shaping.After processing three fork pin 3, stride across interlude, turning goes out the external screw thread of the other end, and the length of workpiece by regulation is cut off.
In embodiment 1, the utility model is put into the hole of lathe chuck, right-hand member stretches out chuck 50mm, blocks with the three-jaw on chuck, and lathe tool prolongs axial right-to-left feed, feed length 11 mm, and radial feed amount 2.25 mm, makes two bites at a cherry.Now lathe tool is through the bottom of rectangular recess, and the trident of this processing sections is shaped.Lathe tool prolongs axis and strides across not processing sections F.With threading tool by drawing, with the right-hand member of trident for benchmark is moved to the left 22mm, feed, right-to-left car M24x2 external screw thread.With cutter, for benchmark is moved to the left 35mm, workpiece is cut off with the right-hand member of trident, namely complete processing.
Claims (2)
