Description
Technical Field
The invention belongs to the field of leaky cable processing, and particularly relates to a device and a method for punching a copper strip of an outer conductor of a palindromic structure sectional coupling leaky cable.
Background
The system loss performance index of the leaky cable is defined as the sum of the transmission attenuation and the coupling loss of the leaky cable, and the index is an important basis for the link design. The outer conductor of the traditional leaky cable is generally provided with one or a class of slotted holes periodically and repeatedly, so that the transmission attenuation constant along the line is consistent with the coupling loss performance, but the total transmission attenuation is increased along with the increase of the coverage distance, so that the system loss of the leaky cable is increased, the system loss of the leaky cable is large, and the requirement of high-speed rail 5G coverage cannot be met. Aiming at the problem, a leaky cable product with sectional coupling and slotting (or performance gradual change) appears in the industry, namely, the attenuation constant and the coupling loss performance of transmission along the line are not constant any more, but the attenuation constant is smaller and the coupling loss is larger closer to the signal source side, and the attenuation constant is larger and the coupling loss is smaller farther away from the signal source side, so that the actual field intensity distribution along the leaky cable is more uniform compared with the conventional leaky cable, and the system loss of the whole line can be greatly reduced.
The sectional coupling leaky cable with the palindromic structure is characterized in that the copper strip is sequentially divided into 1 st to Nth sections according to the type of the periodic grooving, and the structures of the 1 st to Nth sections are the same as those of the Nth to 1 st sections. When the copper strip material is segmented into a palindromic structure, namely the types of the slots are symmetrical about the central axis of the copper strip, the types of the slots at two ends are the same, if the copper strip material is segmented into even sections, the two ends at the middle can be treated as the same section due to the same types of the slots, so that the segmented leaky cable of the palindromic structure can only be segmented into odd sections, N is inevitably odd, and the condition of being segmented into even sections does not exist.
However, for the leaky cable product with the segmented coupling slotting of the palindromic structure at present, copper strip materials with different slotted holes need to be welded, riveted or directly contacted, and a segmented punching device is not provided, so that segmented punching cannot be realized.

The punching module is structurally shown in FIG. 2 and comprises a plurality of punching assemblies which are distributed along the movement direction of the copper strip and are matched with the periodic pitch; the control module is in signal connection with the punching module, sends a control signal to the punching module and is used for controlling the punching module to enable a preset punching assembly to perform punching operation in a punching operation time slot;
the punching assembly is used for forming all slot holes in one period and comprises an upper die holder, a knife edge male die, a punch fixed on the knife edge male die, a knife edge female die, a lower die holder, a guide rail and a protective template; the upper die base is provided with a knife edge male die which is fixedly connected with one end of the guide rail, and the bottom end of the knife edge male die is provided with a punch; the lower die holder is provided with a knife edge female die which is fixed with the other end of the guide rail; the upper die base is positioned right above the lower die base and moves relatively along a vertically arranged guide rail; a protective template is arranged between the knife edge convex die and the knife edge concave die, and the minimum relative distance between the protective template and the knife edge convex die is provided with a first gear and a second gear, so that the punching assembly is in a working state and a standby state respectively;
the protective template is provided with a through hole matched with a punch, when the punching assembly is in a working state, the minimum relative distance between the protective template and the knife edge convex die is a first gear, and when the upper die holder falls down along the guide rail, the punch at the bottom end of the knife edge convex die penetrates through the protective template and is matched with the knife edge concave die arranged on the lower die holder, so that the punching of the copper strip is completed; when the punching assembly is in a standby state, the minimum relative distance between the protective template and the knife edge convex die is a second gear, and when the upper die holder falls down along the guide rail, the punch at the bottom end of the knife edge convex die is shielded by the protective template and does not contact with a copper strip.
The punching assemblies keep adjacent relation according to the positions of the slotted holes formed by the punching assemblies on the copper strip; namely, when the copper strip is sequentially divided into sections 1 to N, the punching assemblies for forming the slotted holes of the sections N and N-1 are adjacent, and N =2, 3, …, N;
preferably, the punching assemblies are sequentially arranged according to the positions of the slotted holes formed by the punching assemblies on the copper strip; specifically, the method comprises the following steps: when the copper strip is divided into 1 st to Nth sections in sequence according to the types of the periodic grooves, the punching assemblies for forming the 1 st to Nth sections of the groove holes are 1 st to Nth punching assemblies respectively, and the 1 st to Nth punching assemblies are arranged in sequence. Preferably, the 1 st to Nth punching assemblies are sequentially arranged in the drawing direction of the copper strip according to the 1 st to Nth sequence, namely the 1 st punching assembly is close to the drawn end of the copper strip; according to the sequence, the switching control of the copper strip material segmentation section is easy, and the efficiency is high.
Preferably, when the copper strip is segmented into the palindromic structure, namely the copper strip is sequentially divided into 1 st to nth sections according to the type of the periodic grooving, the structures of the 1 st to nth sections are the same as those of the N st to 1 st sections, the sections matched with the palindromic structure form periodic slotted holes by using the same punching assembly, the punching assemblies for forming the slotted holes of the 1 st to nth sections are respectively the 1 st to (N + 1)/2 th punching assemblies, and the 1 st to (N + 1)/2 th punching assemblies are sequentially arranged. Because the copper strip material is segmented into the palindromic structure, the segments at the two ends of the copper strip material are respectively matched, an independent segment exists in the middle, the segments are cardinal numbers, the type of the slotted holes is half of the number of the segments plus 1, the slotted hole punching of the whole section of the copper strip material can be completed only by punching components with corresponding numbers, the copper strip material segmentation and the type matching of the slots in the segments are only needed, and the length of each segment does not influence the arrangement mode among a plurality of punching components. Generally, when the coaxial cable satisfies the length of the laying section, signal radiation is performed from both ends of the laying section, so that the design of the sectionally coupled coaxial cable is mostly a symmetrical palindrome structure. Half of the punch assemblies are designed to significantly reduce the cost of the apparatus, but the cost of control is slightly increased.
The copper strip material of sectional coupling's leaky cable needs the segmentation fluting generally can carry out terrace die change or design a plurality of punching assemblies, and a plurality of punching assemblies switch to in proper order and punch a hole and open a slot on the station of punching a hole to satisfy current marching type copper strip material traction mode. However, the movement mode of the punching assembly can be changed due to the design, and the precision requirement of the leaky cable production process on the copper strip punching is very high, so that the movement precision of the punching assembly for switching paths and the punching stroke is quite high, the cost of the outer conductor copper strip punching device is increased rapidly, and the debugging difficulty is greatly increased. The invention adopts the design of continuously arranging a plurality of punching assemblies along the moving direction of the copper strip material, and can complete the punching of the copper strip material of the external conductor of the modified palindromic structure sectional coupling leaky cable only by one-time loading and debugging of the punching assemblies for one type of leaky cable.
However, the punching component layout device provided by the invention changes the relative position of the punch on the copper strip, and the period and the pitch need to be registered again when the slotted holes at the segments are switched. To simplify pitch registration control, the multiple punch assemblies are arranged in a matched pitch arrangement, i.e., each punch assembly forms all slots in one cycle, and the positions between the multiple punch assemblies are arranged in a matched cycle pitch. The design simplifies the periodic registration problem during slot hole switching at the subsection, but still has the traction control difficulty.
The invention provides a method for punching a copper strip material of an outer conductor of a palindromic structure sectional coupling leaky cable, which comprises the following steps of:
the copper strip material punching device of the external conductor of the segmented coupling leaky cable with the palindromic structure is arranged by applying the punching components according to the adjacent positions of the slots formed by the punching components on the copper strip material;
enabling one of the punching assemblies to be in a working state according to the position of the punching assembly; when one of the punching assemblies is in a working state, all other punching assemblies are in a standby state, and the punching assemblies are in a working state in sequence;

the traction module pulls the copper strip to step forward by a distance of 2 pitches or keeps still at the beginning of the first punching operation time slot of the section according to a control signal containing the traction step number +1 or-1 sent by the control module,
the punching module switches the punching assembly provided with the corresponding slotted hole in the next section to be in a working state, and other punching assemblies are in a standby state, so that the copper strip is punched to complete the first punching operation in the section;

when the adjacent mode of the punching assembly with the corresponding slotted hole in the next section and the punching assembly with the corresponding slotted hole in the current section is cis-adjacent, namely the punching assembly with the corresponding slotted hole in the next section is far away from the pulled end of the copper strip relative to the punching assembly with the corresponding slotted hole in the current section, the control module sends a control signal containing the pulling step number-1 to the pulling module;
when the adjacent mode of the punching assembly with the corresponding slotted hole in the next section and the punching assembly with the corresponding slotted hole in the current section is trans-adjacent, namely the punching assembly with the corresponding slotted hole in the next section is close to the pulled end of the copper strip relative to the punching assembly with the corresponding slotted hole in the current section, the control module is enabled to send a control signal containing the pulling step number +1 to the pulling module;
the traction module sends a control signal containing traction step number +1 or-1 according to the control module, and pulls the copper strip to step forward by a distance of 2 pitches or keep still when the first punching operation time slot of the section starts, specifically:
the traction module sends a control signal containing traction step number +1 according to the control module, and pulls the copper strip to step forward by a distance of 2 pitches at the beginning of the first punching operation time slot of the section; or
And the traction module is used for drawing the copper strip material to keep still at the beginning of the first punching operation time slot of the section according to a control signal containing the traction step number-1 sent by the control module.
The invention provides a method for punching a copper strip of an outer conductor of a palindromic structure sectional coupling leaky cable, which aims at the punching device for the copper strip of the outer conductor of the palindromic structure sectional coupling leaky cable, and can keep the traction step length unchanged when the punching assemblies are switched among different sections by utilizing the characteristic that the positions among a plurality of punching assemblies are matched with the period pitch, and realize the switching of different punching assemblies among the sections only through the change of the step number.
Preferably, a plurality of punching assemblies are adjacent in a cis form, and when the punching assemblies are switched among the sections, only the working state or the standby state of the punching assemblies needs to be switched, so that the efficiency is highest. When the copper strip material is segmented into the palindromic structure, the adjacent states of the punching assemblies are respectively switched by the aid of the shared punching assemblies due to the palindromic structure, and the time slot length during interval switching is twice as long as the time slot of in-segment punching operation under the condition that the movement speed is unchanged although the switching of the anti-adjacent punching assemblies is time-consuming, but after the leaky cable outer channel strip lifting processing of one laying interval is finished, the copper strip material of the next laying interval can be directly loaded without debugging the punching assemblies, so that the large-scale, mass and continuous production of the segmented coupling cable outer conductor copper strip material with the palindromic structure is conveniently realized.
