Description

Technical Field

[0001] The invention relates to a device for twisting a wire clamp cap. Background Art

[0002] A wire twisting machine is a machine that twists multiple strands of wire into one strand. In addition to fully automatic wire twisting machines, there is also a type of small wire twisting machine that requires manual operation.

[0003] Fully automatic twisting machines are usually installed in assembly lines. The robot puts several strands of wires that have been stripped in the previous process into the twisting machine, and then twists them into one strand. The robot then passes the wire to the next process for capping. This type of twisting machine is usually suitable for larger companies, especially those specializing in the production of wires or cables. For general small companies, the cost is too high, and twisting and capping are usually only a small step.

[0004] Another type of wire twisting machine suitable for small businesses is usually handheld. Put multiple stripped wires into the twisting groove of the twisting head, press the switch, and the twisting structure in the twisting head rotates to twist the wires into one strand. This type of wire twisting machine requires two hands to operate at the same time. The operator needs to first arrange the wire strands and put them into the twisting cavity, and then press the button. It is extremely inconvenient to operate and the twisting efficiency is slow. There are also such handheld twisting machines that are modified into foot-operated ones, that is, the button in the twisting head is set to the outside, and the button is pressed by foot to control the work of the twisting head. This type of wire twisting machine requires the operator to have more skilled operating experience. If the operator is not skilled enough and the button is pressed before the wire strands are neatly arranged, it will result in the production of wire strands that do not meet the requirements and a high defective rate.

[0035] As a further description of the above technical solution: the push rod 6 is a long square rod, and the front end of the push rod 6 is provided with a flat block with an arc-shaped top. When the wire harness after the twisting operation is put into the positioning hole 501, the operator further pushes the wire harness, the wire harness passes through the positioning hole 501 and contacts the spring and presses the spring 101, the circuit of the cap clamping device is turned on, the push rod 6 passes through the positioning seat 5 and enters the positioning hole 501 and squeezes the wire harness in the positioning hole 501, and the cap clamping operation is completed.
