Description

Technical Field

[0001] The present invention relates to the field of crimping machines, and in particular to a cable crimping machine for electric power engineering construction. Background Art

[0002] Power engineering is closely related to the production, transmission and distribution of electric energy. Crimping machines are one of the necessary tools in the power industry and play an extremely important role in conductor connection during line infrastructure construction and line maintenance.

[0003] During use, the worker places the cable housing to be crimped into the crimping machine. The worker then controls the hydraulic system in the crimping machine to crimp the cable housing. Generally, the cylindrical cable housing needs to be crimped into a regular hexagonal prism. However, existing crimping machines have the following defects: 1. Since the cable housing has a certain length, when crimping a certain area, the cable housing part beside the crimping area will droop downward, which requires two workers to lift the cable housing on the side, which is a large workload.

[0004] 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 crimping machine, the worker needs to move the cable shell after crimping one section of the cable shell, and then crimp the next section of the cable shell. However, in this process, since the position where the first section of the cable shell is crimped is located inside the crimping machine, it is not convenient for the worker to observe the moving distance of the cable shell. It is necessary to move back and forth to ensure that the position of the second section of the cable shell to be crimped is just located between the dies of the crimping machine, otherwise there will be a problem of discontinuity in the two crimping positions. Moreover, since the cable shell needs to be crimped into a regular hexagonal prism, the edges of the two crimping positions need to be in the same straight line, otherwise it will affect subsequent use. As a result, when moving the cable shell, the worker not only needs to observe the moving distance of the cable shell, but also needs to keep the cable shell from rotating during movement, which is more mentally consuming. Summary of the Invention

[0005] In order to overcome the shortcomings of existing crimping machines, such as large workload when used and the need to maintain the crimped state of the cable housing, which is quite mentally consuming, the present invention provides a cable crimping machine for power engineering construction.

[0009] Optionally, the upper mold base is detachably connected to the fixed base, and the upper limit base is detachably connected to the telescopic driving member.

[0010] Optionally, a grinding block is installed on each end of the upper side surface of the lower limit seat, and the opposite sides of the two grinding blocks are grinding surfaces.

[0014] Optionally, the short sides of the grooves of the isosceles trapezoidal structures of the upper limit seat and the lower limit seat are respectively rotatably connected to a horizontally placed cylindrical roller, and the crimping position of the cable is clamped and limited by the upper and lower cylindrical rollers.

[0015] Optionally, when the upper and lower cylindrical rollers clamp and limit the crimping position of the cable housing, the hypotenuse sides of the grooves of the isosceles trapezoidal structures of the upper limit seat and the lower limit seat do not contact the crimped cable housing.

[0016] Compared with the prior art, the present invention has the following advantages: the upper limit seat and the lower limit seat are brought close to each other to clamp and support the cable housing part on one side of the crimping position, while the cable housing part on the other side of the crimping position can be lifted by a worker, thereby reducing the use of personnel and workload; When continuously crimping longer cable housings, the present invention allows the worker who assists in lifting the cable housing on the other side to only push the cable housing without having to worry about controlling the moving distance and non-rotating state of the cable housing. The limiting space between the two grooves of the upper limit seat and the lower limit seat is thereby utilized to achieve rapid continuous crimping of the cable housings.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1: A cable crimping machine for power engineering construction, such as Figure 1-Figure 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; It also includes a telescopic drive member 5; the telescopic drive member 5 is an electric push rod; two pairs of telescopic drive members 5 distributed upper and lower are installed on the side wall of the fixed seat 2; the telescopic ends of the upper pair of telescopic drive members 5 are commonly connected to the upper limit seat 6, and the telescopic ends of the lower pair of telescopic drive members 5 are commonly connected to the lower limit seat 7.

[0021] The upper limit seat 6 and the lower limit seat 7 are both provided with grooves of isosceles trapezoidal structure on opposite sides, and the long sides of the two grooves are opposite to each other.

[0022] When the upper limit seat 6 and the lower limit seat 7 move closer to each other to form a limit space, the top edge of the cable shell 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 extruded into a regular hexagonal prism contacts the short side of the groove of the isosceles trapezoidal structure of the lower limit seat 7.

[0023] The upper mold base 4 is detachably connected to the fixed base 2, and the upper limit seat 6 is detachably connected to the telescopic driving member 5, so that personnel can easily remove both the upper mold base 4 and the upper limit seat 6 and place the cable housing.

[0024] In this embodiment, the crimping machine base 1 is pre-connected to an external hydraulic pump, and the external hydraulic pump can control the hydraulic rod 101 in the crimping machine base 1 to rise. This structure is common knowledge and will not be described in detail here.

[0025] During the crimping operation, the worker places the cable housing to be crimped between the lower die base 3 and the upper die base 4, and then controls the hydraulic rod 101 to drive the lower die base 3 to rise, so that the lower die base 3 and the upper die base 4 cooperate to squeeze the cylindrical cable housing into a regular hexagonal prism, completing the crimping operation.

[0026] Furthermore, when the worker places the cable shell to be crimped between the lower mold base 3 and the upper mold base 4, the cable shell 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 members 5 to respectively drive the upper limit seat 6 and the lower limit seat 7 to move, the upper limit seat 6 and the lower limit seat 7 are brought close to each other to clamp and support the cable shell part on one side of the crimping position, while the cable shell part on the other side of the crimping position can be lifted with the assistance of one worker, thereby reducing the use of personnel and reducing workload.

[0027] Furthermore, when it is necessary to continuously crimp longer cable housings, in order to solve the problem that workers not only need to observe the moving distance of the cable housing when moving the cable housing, but also need to keep the cable housing from rotating during movement, the upper limit seat 6 and the lower limit seat 7 are designed to not only clamp and support, but also limit the crimped position of the cable housing. Specifically, after the first section of the cable housing is crimped, the first section of the cable housing that has been crimped is moved between the upper limit seat 6 and the lower limit seat 7, and then the two pairs of telescopic driving members 5 are controlled to respectively drive the upper limit seat 6 and the lower limit seat 7 to move closer to each other, so that a limiting space is formed between the upper limit seat 6 and the lower limit seat 7. At this time, Figure 1 As shown, the top side of the cable housing 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 side of the cable housing extruded into a regular hexagonal prism contacts the short side of the groove of the isosceles trapezoidal structure of the lower limit seat 7, so that the top side and bottom side of the cable housing extruded into a regular hexagonal prism are limited by the short sides of the two grooves of the upper limit seat 6 and the lower limit seat 7 respectively, so that the cable housing can only move horizontally and cannot rotate, and because the upper limit seat 6 and the lower limit seat 7 move closer to each other, the distance between the two grooves of the upper limit seat 6 and the lower limit seat 7 is smaller than the outer diameter of the cylindrical part of the cable housing, so at this time Only the part of the cable shell that is squeezed 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 part of the cable shell moves to the side walls of the upper limit seat 6 and the lower limit seat 7, it will be blocked and unable to move further, ensuring that the next crimping position of the cable shell is precisely located in the crimping space between the lower mold seat 3 and the upper mold seat 4. Therefore, at this time, the worker who assists in lifting the cable shell on the other side only needs to push the cable shell, without having to spend time controlling the moving distance and non-rotating state of the cable shell, thereby utilizing the limit space between the two grooves of the upper limit seat 6 and the lower limit seat 7 to achieve rapid continuous crimping operations of the cable shell.

[0028] Example 2: Based on Example 1, Figure 1-Figure 4 As shown, a grinding block 8 is installed at each end of the upper side surface of the lower limit seat 7, and the opposite sides of the two grinding blocks 8 are grinding surfaces.

[0029] A dust suction port 701 is respectively provided at both ends of the upper side surface of the lower limit seat 7, and each of the dust suction ports 701 is located on the side surface of one of the grinding blocks 8. A dust collector 9 is installed on the crimping machine base 1, and two telescopic pipes 10 are connected between the dust collector 9 and the lower limit seat 7. The telescopic pipes 10 can be extended and retracted in coordination with the lifting and lowering action of the lower limit seat 7, and each of the telescopic pipes 10 is connected to one of the dust suction ports 701.

[0030] When the upper limit seat 6 moves downward and forms a limiting space with the lower limit seat 7 , the grinding block 8 contacts the lower side surface of the upper limit seat 6 .

[0031] The vacuum cleaner 9 is provided with a detachable debris collection box, which is convenient for personnel to open the debris collection box and remove the debris.

[0032] In this embodiment, considering that after the cable housing is crimped, burrs will appear on the edges of the two sides of the regular hexagonal prism structure of the cable housing due to the transformation of the cylindrical structure into a regular hexagonal prism structure, workers usually grind the burrs with grinding strips after the crimping is completed, which is a large workload. In addition, in general, cable housings are crimped outdoors, and the grinding debris will splash and pollute the outdoor environment. Therefore, the present invention designs a grinding block 8. When the upper limit seat 6 and the lower limit seat 7 are further moved closer to each other to form a limit space, the two grinding blocks 8 are respectively located on the two sides of the regular hexagonal prism structure of the cable housing. On the side edge moving path, when the worker pushes the cable housing, the burrs on the edges on both sides are polished away by two polishing blocks 8, and at this time the polishing block 8 is 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 polishing block 8. The upper limit seat 6, the lower limit seat 7 and the polishing block 8 form a sealing surface on one side, and the dust suction port 701 is located on the other side. The sealing surface is used to reduce the splashing of polishing debris outward, and the suction force is generated by starting the vacuum cleaner 9, and then the polishing debris is sucked and collected through the dust suction port 701 and the telescopic pipe 10, thereby reducing the workload of the workers.

[0033] Example 3: Based on Example 2, 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 rotatably connected to a horizontally placed cylindrical roller 11.

[0034] When the upper and lower cylindrical rollers 11 clamp and limit the crimping position of the cable housing, the oblique sides of the grooves of the isosceles trapezoidal structures of the upper limit seat 6 and the lower limit seat 7 do 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.

[0035] In this embodiment, considering that during continuous crimping, the crimped part of the cable shell needs to move in the grooves of the upper limit seat 6 and the lower limit seat 7, in order to reduce the contact wear between the cable shell and the upper limit seat 6 and the lower limit seat 7, a cylindrical roller 11 is designed, which not only meets the limiting requirements of the crimped part of the cable shell, but also allows the cylindrical roller 11 to roll together when the crimped part of the cable shell moves on the cylindrical roller 11, so as to reduce wear and make it more labor-saving for workers to push the cable shell.

[0036] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes 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.
