Description

Technical Field

[0001] This invention relates to the field of crimping machines, and more particularly to a cable crimping machine for power engineering construction. Background Technology

[0002] Power engineering is closely related to power generation, transmission, and distribution. Crimping machines are one of the essential tools in the power industry, playing an extremely important role in conductor splicing during basic line construction and line maintenance.

[0003] During use, workers place the cable shells to be crimped into the crimping machine, and then control the hydraulic system inside the machine to crimp the cable shells. Generally, cylindrical cable shells need to be crimped into regular hexagonal prisms. However, existing crimping machines have the following drawbacks:

[0004] 1. Because the cable shell has a certain length, when crimping a certain area, the part of the cable shell next to the crimping area will droop downwards, which requires two workers to lift the cable shell from the side, resulting in a large workload for personnel.

[0005] 2. Due to the limited crimping area of ​​the crimping machine, when the length of the cable shell to be crimped is longer than the crimping area of ​​the machine, the worker needs to move the cable shell after crimping one section before crimping the next section. However, since the first section of the cable shell is located inside the crimping machine, it is not convenient for the worker to observe the movement distance of the cable shell. The worker needs to move the cable shell back and forth to ensure that the second section of the cable shell is located between the crimping molds of the machine. Otherwise, there will be a problem of discontinuity between the two crimping positions. Furthermore, since the cable shell needs to be crimped into a regular hexagonal prism, the edges of the two crimping positions need to be on the same straight line. Otherwise, it will affect subsequent use. This means that when moving the cable shell, the worker not only needs to observe the movement distance of the cable shell, but also needs to ensure that the cable shell does not rotate during the movement, which is quite mentally taxing. Summary of the Invention

[0006] In order to overcome the shortcomings of existing crimping machines, which require a large amount of manpower and need to maintain the crimped state of the cable shell, and are quite mentally taxing, this invention provides a cable crimping machine for power engineering construction.

[0007] The technical implementation scheme of the present invention is as follows: a cable crimping machine for power engineering construction, comprising a crimping machine base, a fixed base, a lower die base, and an upper die base; a U-shaped fixed base is installed on the crimping machine base; the crimping machine base has a hydraulic rod; the hydraulic rod passes through the fixed base and is fitted with the lower die base; the upper die base is installed on the upper part of the fixed base; a crimping space is formed between the lower die base and the upper die base, and the lower die base is pushed up by the hydraulic rod to cooperate with the upper die base to compress the columnar outer shell of the cable into a regular hexagonal prism; it also includes telescopic drive components; two pairs of telescopic drive components are installed on the side wall of the fixed base, distributed vertically; the telescopic ends of the upper pair of telescopic drive components are connected to an upper limit seat, and the telescopic ends of the lower pair of telescopic drive components are connected to a lower limit seat; the upper limit seat and the lower limit seat support the side portion of the cable crimping position.

[0008] Optionally, the upper limit seat and the lower limit seat are provided with isosceles trapezoidal grooves on opposite sides, and the long sides of the two grooves are opposite to each other.

[0009] Optionally, when the upper limit seat and the lower limit seat move closer to each other to form a limiting space, the top edge of the cable shell, which is squeezed into a regular hexagonal prism, contacts the short side of the groove of the isosceles trapezoidal structure of the upper limit seat, and the bottom edge of the cable shell, which is squeezed into a regular hexagonal prism, contacts the short side of the groove of the isosceles trapezoidal structure of the lower limit seat.

[0010] Optionally, the upper mold base and the fixed base are detachably connected, and the upper limit seat and the telescopic drive are detachably connected.

[0011] Optionally, a grinding block is installed at each end of the upper side of the lower limit seat, and the opposite sides of the two grinding blocks are grinding surfaces.

[0012] Optionally, a dust suction port is provided at each of the two ends of the upper side of the lower limit seat. Each dust suction port is located on the side of one of the grinding blocks. A vacuum cleaner is installed on the pressing machine base. Two telescopic pipes are connected between the vacuum cleaner and the lower limit seat. Each telescopic pipe is connected to one of the dust suction ports. The vacuum cleaner generates suction force and collects the grinding debris through the dust suction ports.

[0013] Optionally, after the upper limit seat moves down and forms a limiting space with the lower limit seat, the grinding block comes into contact with the lower side of the upper limit seat.

[0014] Optionally, the vacuum cleaner is equipped with a removable debris collection box.

[0015] Optionally, a horizontally placed cylindrical roller is rotatably connected to the short side of the groove of the isosceles trapezoidal structure of the upper limit seat and the lower limit seat, respectively, so as to clamp and limit the crimping position of the cable by the two cylindrical rollers.

[0016] Optionally, when the upper and lower cylindrical rollers clamp and limit the pressing position of the cable housing, the inclined side of the groove of the isosceles trapezoidal structure of the upper limit seat and the lower limit seat does not contact the pressed cable housing.

[0017] Compared with the prior art, the present invention has the following advantages: the present invention clamps and supports the cable shell part on one side of the crimping position by bringing the upper limit seat and the lower limit seat close to each other, while the cable shell part on the other side of the crimping position can be lifted by one worker, reducing the use of personnel and reducing the workload.

[0018] When continuously crimping long cable housings, the worker assisting in lifting the other side of the cable housing only needs to push the cable housing, without having to spend time controlling the movement distance or the non-rotation state of the cable housing. Thus, the limiting space between the upper and lower limit seats can be used to quickly perform continuous crimping operations on the cable housing. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1: A cable crimping machine for power engineering construction, such as Figures 1-4 As shown, it includes a crimping machine base 1, a fixed base 2, a lower die base 3, and an upper die base 4; the crimping machine base 1 is equipped with a U-shaped fixed base 2; the crimping machine base 1 has a hydraulic rod 101; the hydraulic rod 101 passes through the fixed base 2 and is equipped with the lower die base 3; the upper die base 4 is installed on the upper part of the fixed base 2.

[0026] It also includes a telescopic drive component 5; the telescopic drive component 5 is an electric push rod; two pairs of telescopic drive components 5 are installed on the side wall of the fixed base 2, which are distributed vertically; the telescopic ends of the upper pair of telescopic drive components 5 are connected to an upper limit seat 6, and the telescopic ends of the lower pair of telescopic drive components 5 are connected to a lower limit seat 7.

[0027] The upper limit seat 6 and the lower limit seat 7 each have an isosceles trapezoidal groove on their opposite sides, and the long sides of the two grooves are opposite each other.

[0028] When the upper limit seat 6 and the lower limit seat 7 move closer to each other to form a limiting space, the top edge of the cable shell, which is squeezed into a regular hexagonal prism, contacts the short side of the groove of the isosceles trapezoidal structure of the upper limit seat 6, and the bottom edge of the cable shell, which is squeezed into a regular hexagonal prism, contacts the short side of the groove of the isosceles trapezoidal structure of the lower limit seat 7.

[0029] The upper mold base 4 and the fixed base 2 are detachably connected, and the upper limit seat 6 and the telescopic drive component 5 are detachably connected, making it easy for personnel to remove both the upper mold base 4 and the upper limit seat 6 and put the cable housing in.

[0030] In this embodiment, a hydraulic pump is pre-connected to the crimping machine base 1. The hydraulic pump can control the rise of the hydraulic rod 101 inside the crimping machine base 1. This structure is common knowledge and will not be described in detail here.

[0031] During the crimping operation, the worker places the cable shell to be crimped between the lower mold base 3 and the upper mold base 4. Then, the worker controls the hydraulic rod 101 to drive the lower mold base 3 to rise, so that the lower mold base 3 and the upper mold base 4 cooperate to squeeze the cylindrical cable shell into a regular hexagonal prism, thus completing the crimping operation.

[0032] Furthermore, when the worker places the cable housing to be crimped between the lower mold base 3 and the upper mold base 4, the cable housing part on the crimping position side is placed between the upper limit seat 6 and the lower limit seat 7. By controlling the two pairs of telescopic drive parts 5, the upper limit seat 6 and the lower limit seat 7 are moved respectively, so that the upper limit seat 6 and the lower limit seat 7 move closer to each other to clamp and support the cable housing part on the crimping position side. The cable housing part on the other side of the crimping position can be lifted by one worker, reducing the number of personnel and the workload.

[0033] Furthermore, when continuous crimping of long cable shells is required, to address the issue of workers needing to observe the moving distance of the cable shell while preventing it from rotating during movement, the upper limit seat 6 and lower limit seat 7 are designed not only to clamp and support but also to limit the crimped position of the cable shell. Specifically, after crimping the first section of the cable shell, the crimped section is moved between the upper limit seat 6 and lower limit seat 7. Then, the two pairs of telescopic drive components 5 are controlled to move the upper limit seat 6 and lower limit seat 7 closer together, creating a limiting space between them. Figure 1 As shown, the top edge of the cable shell, which is extruded into a regular hexagonal prism, contacts the short side of the groove of the isosceles trapezoidal structure of the upper limit seat 6, and the bottom edge of the cable shell, which is extruded into a regular hexagonal prism, contacts the short side of the groove of the isosceles trapezoidal structure of the lower limit seat 7. Thus, the short sides of the two grooves of the upper limit seat 6 and the lower limit seat 7 respectively limit the top and bottom edges of the cable shell, making the cable shell only able to move horizontally and unable to rotate. Furthermore, due to the further movement of the upper limit seat 6 and the lower limit seat 7 closer together, the distance between the two grooves of the upper limit seat 6 and the lower limit seat 7 is less than the outer diameter of the cylindrical portion of the cable shell. Therefore, at this point… Only the portion of the cable housing that is compressed into a regular hexagonal prism can move between the two grooves of the upper limit seat 6 and the lower limit seat 7. When the cylindrical portion of the cable housing moves to the side wall of the upper limit seat 6 and the lower limit seat 7, it will be blocked and unable to move further. This ensures that the next crimping position of the cable housing is accurately located in the crimping space between the lower die seat 3 and the upper die seat 4. Therefore, at this time, the worker assisting in lifting the other side of the cable housing only needs to push the cable housing. There is no need to spend time controlling the moving distance and non-rotating state of the cable housing. Thus, the limiting space between the two grooves of the upper limit seat 6 and the lower limit seat 7 is used to realize the continuous crimping operation of the cable housing quickly.

[0034] Example 2: Based on Example 1, such as Figures 1-4 As shown, a grinding block 8 is installed at each end of the upper side of the lower limit seat 7, and the opposite sides of the two grinding blocks 8 are grinding surfaces.

[0035] The lower limit seat 7 has a dust suction port 701 at each of its two upper sides. Each dust suction port 701 is located on the side of a grinding block 8. A vacuum cleaner 9 is installed on the crimping machine base 1. Two telescopic pipes 10 are connected between the vacuum cleaner 9 and the lower limit seat 7. The telescopic pipes 10 can extend and retract in coordination with the lifting and lowering action of the lower limit seat 7. Each telescopic pipe 10 is connected to a dust suction port 701.

[0036] When the upper limit seat 6 moves down and forms a limiting space with the lower limit seat 7, the grinding block 8 comes into contact with the lower side of the upper limit seat 6.

[0037] The vacuum cleaner 9 is equipped with a detachable debris collection box, which makes it easy for personnel to open the debris collection box and remove the debris.

[0038] In this embodiment, considering that after the cable shell is crimped, due to the transformation of the cylindrical structure into a regular hexagonal prism structure, burrs will appear on both sides of the regular hexagonal prism structure of the cable shell. Generally, after crimping, workers use hand-held grinding sticks to grind the burrs, which is a large amount of work. In addition, cable shells are usually crimped outdoors, and the grinding debris will fly and pollute the outdoor environment. Therefore, this invention designs grinding blocks 8. When the upper limit seat 6 and the lower limit seat 7 move closer to each other to form a limiting space, the two grinding blocks 8 are located on the two sides of the regular hexagonal prism structure of the cable shell. On the side edge movement path, when the worker pushes the cable shell, the burrs on both sides of the edge are removed by two grinding blocks 8. At this time, the grinding blocks 8 are in contact with the lower side of the upper limit seat 6, and the dust suction port 701 is located on the side of the grinding blocks 8. The upper limit seat 6, the lower limit seat 7 and the grinding blocks 8 form a sealing surface on one side, while the dust suction port 701 is located on the other side. The sealing surface reduces the outward splashing of grinding debris. By starting the vacuum cleaner 9, a suction force is generated, and the grinding debris is sucked up and collected through the dust suction port 701 and the telescopic pipe 10, thereby reducing the workload of the worker.

[0039] Example 3: Based on Example 2, such as Figure 1 and Figure 4 As shown, the short sides of the grooves of the isosceles trapezoidal structures of the upper limit seat 6 and the lower limit seat 7 are respectively rotatably connected to a horizontally placed cylindrical roller 11.

[0040] When the upper and lower cylindrical rollers 11 clamp and limit the crimping position of the cable housing, the inclined side of the groove of the isosceles trapezoidal structure of the upper limit seat 6 and the lower limit seat 7 does not contact the crimped cable housing, so as to reduce the contact wear between the crimped part of the cable housing and the upper limit seat 6 and the lower limit seat 7 when moving.

[0041] In this embodiment, considering that during continuous crimping, the crimped portion of the cable housing needs to move within the grooves of the upper limit seat 6 and the lower limit seat 7, a cylindrical roller 11 is designed to reduce contact wear between the cable housing and the upper limit seat 6 and the lower limit seat 7. This design not only meets the limiting requirements for the crimped portion of the cable housing, but also allows the cylindrical roller 11 to roll in coordination with the crimped portion of the cable housing as it moves on the roller, thus reducing wear and making it easier for workers to push the cable housing.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
