Description

Technical Field

[0001] This utility model belongs to the field of electrode copper tube processing technology, and more specifically, it relates to a high-precision coiling system for electrode copper tubes. Background Technology

[0002] To meet the high-precision processing requirements of electrode copper tubes, a disc drawing machine is needed to process the copper tubes into specific sizes and shapes. First, the copper tube to be processed is released from the feeder. The pre-treated end is passed through the die and placed in the groove of the drawing disc. At this time, the pressure roller applies downward pressure, pressing the blank tightly into the groove on the outside of the disc. The main motor starts and drives the drawing disc to rotate. The friction between the disc groove and the copper tube causes the copper tube to move forward. The copper tube is forcibly pulled through the drawing die and undergoes plastic deformation. The stretched copper tube will be wound around the outside of the take-up reel and arranged in a uniform spiral shape.

[0003] For example, CN211218066U discloses a continuous hot drawing system for titanium alloy wire, including a wire feeding reel, at least two sets of heating and drawing mechanisms, and a take-up reel arranged sequentially along the travel direction of the titanium alloy wire. A guiding mechanism is provided between adjacent heating and drawing mechanisms to adjust the travel direction of the titanium alloy wire from the outlet end of the preceding heating and drawing mechanism to the inlet end of the following heating and drawing mechanism. Each heating and drawing mechanism includes an induction heating coil, a die, and a disc drawing machine arranged sequentially along the travel direction of the titanium alloy wire. The inlet end of the induction heating coil serves as the wire inlet end of the heating and drawing mechanism, and the outlet end of the disc drawing machine serves as the wire outlet end of the heating and drawing mechanism. This application, by providing at least two sets of heating and drawing mechanisms between the wire feeding reel and the take-up reel, enables continuous heating and drawing of the titanium alloy wire, increasing the drawing deformation of the titanium alloy wire in a single operation.

[0004] Based on the above, when coiling copper tubes of different diameters, it is necessary to change the appropriate clamping rollers and stretching dies according to the diameter specifications of the copper tubes. This results in workers having to frequently disassemble and assemble parts and calibrate positioning, which increases the workload. In addition, the whole process takes a long time, resulting in long downtime of the coiling equipment and affecting the processing efficiency of the electrode copper tubes. Utility Model Content

[0022] The automatic replacement structure includes a clamping drive 106 and a high-precision lead screw 107. The clamping drive 106 is bolted to the upper part of the limit support base 1. The high-precision lead screw 107 is rotatably connected to the upper part of the limit support base 1. The high-precision lead screw 107 is coaxially fixedly connected to the output shaft of the clamping drive 106. The high-precision lead screw 107 is threadedly connected to the sliding mounting seat 3 through a threaded pair.

[0023] The automatic replacement structure also includes a pull-out drive 108 and a shift drive 109; the pull-out drive 108 is bolted to the rear side of the limit support base 1, and the output shaft of the pull-out drive 108 is coaxially and fixedly connected to the copper tube pull-out disc 2; the shift drive 109 is bolted to the rear side of the limit support base 1, and the output shaft of the shift drive 109 is coaxially and fixedly connected to the mold mounting base 6.

[0024] The automatic replacement structure also includes a limit mounting rod 110 and a position limiting ring 111; the limit mounting rod 110 is fixedly connected to the right side of the limit support base 1; the position limiting ring 111 is threadedly connected to the front side of the limit mounting rod 110.

[0026] The specific usage and function of this embodiment are as follows: When performing coil drawing processing on the electrode copper tube, first, the copper tube feeding roller is placed on the outside of the limiting mounting rod 110. Then, the position limiting ring 111 is screwed on the front side of the limiting mounting rod 110 to limit the copper tube feeding roller. After the pre-treated copper tube end passes through the copper tube drawing die 601, it is placed in the limiting groove on the outside of the copper tube drawing disc 2. The clamping drive 106 is activated, causing the clamping drive 106 to drive the high-precision lead screw 107 to rotate. When the high-precision lead screw 107 rotates, it will drive the sliding mounting seat 3 to slide along the limiting support base 1, changing the position of the copper tube clamping wheel 5 until the copper tube clamping wheel 5 clamps the copper tube in the copper tube drawing process.

[0030] The specific usage and function of this embodiment: After being drawn, the copper tube will move to the left under the push of the copper tube drawing disc 2 and the copper tube pressing wheel 5. After the end of the copper tube reaches the winding area, the end of the copper tube is manually inserted into the tube end limiting hole 105, and the corresponding winding drive 103 is started, so that the winding drive 103 drives the copper tube winding roller 104 to rotate, and the copper tube is wound around the outside of the copper tube winding roller 104. During the winding process, the copper tube of the next turn will be squeezed and limited by the previous layer of copper tube to automatically complete the tube arrangement. After winding is completed, the end of the copper tube is pulled out of the tube end limiting hole 105, and the wound copper tube will fall automatically by its own gravity. When it is necessary to wind the copper tube into spiral coils of different sizes, the roller changing drive 101 is started, so that the roller changing drive 101 drives the dustproof mounting box 102 to rotate a certain angle, thereby moving the corresponding copper tube winding roller 104 to the winding area. All the drive components used in this application are reciprocating self-locking drive motors.
