The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

Example one

As shown in fig. 1-2, the utility model provides an automatic tangent line device of electric power cable coiling machine, including installing tangent line board 1 on the coiling machine and installing the punching press cylinder 2 on tangent line board 1, the 3 ends of output shaft of punching press cylinder 2 install the saddle 5 through connecting piece 4.

The inclined knife rest 5 is provided with a wire cutting knife 6 with a V-shaped cross section through a fixing piece, a lead frame 7 is arranged on a wire cutting plate 1 right opposite to the bottom of the wire cutting knife 6, the lead frame 7 comprises a fixing seat 702 with a wire through hole 701, a wire guide groove 703 matched with the wire cutting knife 6 is arranged in the middle of the fixing seat 702, a working inner cavity 704 is arranged inside the fixing seat 702 at the bottom of the wire guide groove 703, and a knife falling groove 705 is arranged at the bottom of the working inner cavity 704.

The utility model discloses well punching press cylinder 2 has two kinds with the connected mode of bevel knife rest 5:

the output shaft 3 of the stamping cylinder 2 is connected with the inclined tool rest 5 through a connecting piece 4, wherein the stamping cylinder 2 is vertically installed, and the connecting piece 4 is an articulated shaft which can be adjusted in angle and fixed.

Secondly, the conveying shaft 3 of the punching cylinder 2 is connected with an inclined tool rest 5 through a connection 4, wherein the top of the punching cylinder 2 is connected with the wire cutting plate 1 through an adjustable and fixable hinge shaft, the punching cylinder 2 and the inclined tool rest 5 are kept on the same straight line, and the included angle between the punching cylinder 2 and the inclined tool rest 5 is 180 degrees.

In both of the above two connection methods, the knife guide groove 703 is inclined.

In the first connection mode between the punching cylinder 2 and the inclined tool rest 5, the wire cutter 6 cuts the power cable wire in the wire passing through hole 701 along the wire guide groove 703 under the action of the punching cylinder 2, so that the output shaft 3 of the punching cylinder 2 moves vertically to drive the wire cutter 6 to move obliquely, the force exerted on the power cable by the wire cutter 6 is divided into a horizontal force and a vertical force, the power cable is cut by the vertical force of the wire cutter 6, the horizontal force and the reverse force of the power cable act backwards on the power cable, and then the resistance in the winding direction of the power cable is provided at the moment when the wire cutter 6 acts on the power cable, so that the power cable with a relatively large diameter can be cut.

In the second connection mode of the punching cylinder 2 and the inclined tool rest 5, the acting force of the output shaft 3 of the punching cylinder 2 directly acts on the wire cutting tool 6, so that the wire cutting process is quicker, and the power cable with a relatively smaller diameter of a cutting point is cut.

In the process of cutting the power cable with a relatively small diameter, the cutting at the oblique cutting angle can avoid the downward acting force of the cutting in the vertical direction on the power cable at the contact point, and simultaneously, the impact generated by the contact of the cutting tool 6 in the process of transmitting the power cable is reduced.

The included angle between the inclined knife rest 5 and the tangent plate 1 is 15-45 degrees, the larger the diameter of the electric power cable is, the smaller the included angle between the inclined knife rest 5 and the tangent plate 1 is correspondingly arranged, and the angle of the knife body of the tangent knife 6 is 145-180 degrees.

The side wall of the inclined knife rest 5 is provided with a laser sensor 8 for positioning the position of the knife guide groove 703, and the laser sensor is used for calibrating the contact between the wire cutter 6 and the knife guide groove 703 in each cutting process, so that the fine deviation of the position of the wire cutter 6 in the long-time cutting process is avoided.

The inclined tool rest 5 is provided with buffer rubber pads 9 at the two sides of the thread cutter 6, and the buffer rubber pads are used for buffering the contact between the inclined tool rest 5 and the fixed seat 702 and further determining the thread cutting depth of the thread cutter 6 each time.

The two side parts of the working cavity 704 on the inner wall of the fixing base 702 are conical, and the routing through hole 701 penetrates through the axis of the conical part on the inner wall of the two sides of the fixing base 702, so that the power cable wire can continuously and accurately penetrate out of the routing through hole 701 after the wire is cut.
