Method for press fitting of dropper heart-shaped ring and clamp pipe

Technical Field

The invention relates to the field of contact net dropper processing, in particular to a method for press-fitting a dropper heart-shaped ring and a clamp pipe.

Background

With the rapid development of the high-speed rail technology in China, the high-speed rail technology puts forward more recent and higher requirements on the railway process quality and standard. In an electrified railway line, a contact network is an important component for ensuring the normal operation of the railway. The contact net is lapped on a power supply line of the electrified railway and provides electric power for the electric locomotive and the auxiliary equipment thereof. In a contact network system, a dropper is one of the key factors of the contact performance between a contact network and a locomotive pantograph, and a set of integral dropper needs to be installed every 6~8 meters on a line to suspend a contact line on a catenary, so that the suspension height of the contact line is ensured, and the contact line keeps certain elasticity to ensure that the contact network and the pantograph have good contact relationship. The hanger comprises a hanger wire, a heart-shaped ring and a clamp pipe which are arranged on one side or two sides of the hanger wire, and a wire nose arranged at one end or two ends of the hanger wire. The production process of the dropper mainly comprises the steps of wire inlet and wire cutting, threading, tensioning, crimping, marking and bundling, wherein the threading comprises the step that the dropper wire penetrates through the clamp pipe, the heart-shaped ring and the wire nose, the tensioning refers to the step that the Li Yongdiao string tensions the heart-shaped ring and the clamp pipe, and the crimping comprises the step that the clamp pipe, the wire nose and the dropper are compressed. At present, the production mode of the dropper is mainly manual, and four to five persons are generally adopted as one class to carry out the procedures of the steps. The production mode has the problems of high labor cost, low precision of finished products of the dropper and the like, and particularly has the problems of inconsistent and uneven length and size, insecure crimping or cracking of a clamp pipe and/or a wire nose caused by overlarge crimping force and the like in the manual production mode due to two links of cutting and crimping of the dropper. In the process of crimping the clamp pipe and the dropper wire, prepressing is required firstly, namely, the clamp pipe is clamped and fixed; then, tightening, namely pulling the two ends of the dropper line so as to enable the heart-shaped ring to be tightly abutted with the clamp pipe; and finally, compressing, namely extruding the clamp pipe to enable the dropper wire to be tightly and fixedly connected with the clamp pipe. In the existing crimping process, manual work is mainly used step by step, so that the working efficiency is low on one hand, the requirement of mechanical automatic production cannot be met on the other hand, more importantly, the wire tightening degree is insufficient, the tight abutting between the heart-shaped ring and the clamp pipe is loosened, the compression degree is insufficient, the hanging wire and the clamp pipe are loosened, or the compression degree is overlarge, so that the clamp pipe is cracked.

In view of the above, the present invention is intended to provide a method for press-fitting a dropper core ring and a clamp pipe, which realizes automation of a press-fitting process in a dropper production process by providing a clamp portion, a clamp pressing portion, and the like, thereby improving production efficiency and yield.

Example 1:

referring to fig. 1-4, a method of press fitting a dropper core ring and a clamp pipe, the improvement comprising: the crimping of the centering ring a, the crimping pipe b and the dropper is realized through a crimping module 70, wherein the crimping module 70 comprises a crimping bottom plate 71, a crimping sliding plate 72 arranged on the crimping bottom plate 71 in a sliding manner, a crimping clamping part 73 arranged on the crimping sliding plate 72 in a sliding manner, and a crimping pressing part 74 arranged on the crimping sliding plate 72; the specific crimping process is as follows: step one, a heart-shaped ring a is sleeved on a clamping rod 738 of a clamping device part 73 through a mechanical arm and is supported on a clamping device supporting platform 739 of the clamping device part 73; step two, while the step one is carried out, the clamping pipe b is conveyed to the clamping pressing part 74 through a mechanical hand and is clamped by the clamping pressing fixed block 744 and the clamping pressing movable block 745 of the clamping pressing part 74; thirdly, the manipulator penetrates the dropper line conveyed by the line conveying module 40 from one end, far away from the heart-shaped ring a, of the clamp pipe b and penetrates through the clamp pipe b; step four, the clamping guide part 78 of the clamping module 70 guides the suspension wire passing through the clamping pipe b, and the manipulator bends the suspension wire passing through the clamping pipe b, passes through the clamping pipe b again and winds the heart-shaped ring a; step five, the dropper wire is pulled by the manipulators at the two ends so that the heart-shaped ring a and the clamp pipe b are tightly abutted; sixthly, the clamping and pressing driver 743 of the clamping and pressing part 74 pushes the clamping and pressing movable block 745 to move towards the clamping and pressing fixed block 744 to press the clamping pipe b and the dropper wire so as to complete the pressing operation of the clamping pipe b; seventhly, ejecting the crimping pipe b after crimping from the crimping and pressing fixed block 744 by the crimping ejection part 76 of the crimping module 70; and step eight, the manipulator transfers the dropper wires which are subjected to pressure welding to the next station.

In this embodiment, the clamping bottom plate 71 is used for bearing a clamping sliding plate 72, and an upper clamping fixture portion 73 and a clamping pressing portion 74 thereof, the clamping sliding plate 72 is used for bearing the clamping fixture portion 73 and the clamping pressing portion 74, the clamping fixture portion 73 is used for clamping and positioning the heart ring a, and the clamping pressing portion 74 is used for pressing and connecting the dropper line and the clamping tube b. The reason why the clamping jaw portion 73 is required to be slidable relative to the clamping slide plate 72 is that the heart ring a on the clamping jaw portion 73 moves toward the clamping tube on the clamping nip portion when both ends of the dropper wire are pulled, so that the clamping jaw portion 73 moves toward the clamping nip portion 74 and abuts against the clamping nip portion 74, and the sliding of the clamping jaw portion 73 relative to the clamping slide plate 72 provides a space and a guide rail for the movement of the clamping jaw portion 73, thereby preventing the clamping jaw portion 73 from being damaged when the dropper wire is pulled.

In the specific use process of the embodiment, the coil of the dropper line is discharged and loaded by the loading module 10, the correction module 20 corrects the dropper line, the conveying module 30 conveys the dropper line, after the dropper line conveyed by the conveying module 30 reaches a preset length, the line cutting module 60 performs line cutting operation, and after the line cutting operation is completed, the line feeding module 40 conveys the cut dropper line to the crimping station. During the crimping operation, the mechanical arm for transferring transfers the heart-shaped ring a to the clamping part 73 and is clamped by the clamping rod 738 of the clamping device, transfers the clamping pipe b to the clamping part 74 and pushes the clamping movable block 745 to move towards the clamping fixed block 744 by the clamping actuator 743 for clamping and clamping; the manipulator for threading penetrates a dropper line from one end, far away from the heart-shaped ring a, of the clamp pipe b and penetrates through the end, and the manipulator for winding winds the dropper line on the heart-shaped ring a and penetrates through the clamp pipe b again; after the dropper line is pulled and tensioned, the clamping and pressing actuator 743 drives the clamping and pressing movable block 745 to move towards the clamping and pressing fixed block 744 to press the dropper line and the clamping tube b.

In this embodiment, the reason why the sliding clamping plate 72 needs to be slidable with respect to the clamping base plate 71 is that the dropper wire is still in a pulled state after the clamping fixture portion 73 abuts against the clamping pressing portion 74, and the sliding clamping plate 72 is slidable with respect to the clamping base plate 71, so that the clamping fixture portion 73 and the clamping pressing portion 74 on the sliding clamping plate 72 can be prevented from being damaged when the dropper wire is pulled. The dropper wire is still in the pulled state because the pressing of the clamp pressing portion 74 against the dropper wire and the clamp tube b is performed in a state where the dropper wire is pulled and tensioned. Of course, the sliding movement of the clamp sliding plate 72 with respect to the clamp base plate 71 is not a large-scale displacement, but a small-scale displacement, that is, one end of the clamp sliding plate 72 is fixed to the clamp base plate 71 by, for example, the clamp base plate tension sensor 712, and the amount of sliding movement of the clamp sliding plate 72 with respect to the clamp base plate 71 is only the amount of deformation of the clamp base plate tension sensor 712 when the dropper is pulled.
