Description

Technical Field

[0001] This invention relates to the field of crimping machine technology, specifically to a cable crimping machine used in water conservancy and hydropower engineering construction. Background Technology

[0002] A crimping machine is a commonly used device in water conservancy and hydropower engineering construction for crimping cables. It mainly consists of a frame, an upper crimping head, a lower crimping head, and a hydraulic cylinder that pushes the lower crimping head upwards. During use, the worker places the cable sheath onto the end of the cable, then inserts the cable sheath between the upper and lower crimping heads. The hydraulic cylinder pushes the lower crimping head to move, crimping the cable sheath. Typically, a cylindrical cable sheath needs to be crimped into a regular hexagon.

[0003] Chinese invention patent application number 202510998050.1 discloses a cable crimping machine for power engineering construction, including a crimping machine base, a fixed base, a lower mold base, and an upper mold base; the crimping machine base is equipped with a U-shaped fixed base; the crimping machine base has a hydraulic rod; by the upper limit seat and the lower limit seat approaching each other, the cable shell part on one side of the crimping position is clamped and supported, while the cable shell part on the other side of the crimping position can be lifted by one worker, reducing the number of personnel required. The worker assisting in lifting the other side of the cable shell only needs to push the cable shell, without having to spend time controlling the movement distance and non-rotation state of the cable shell. Thus, the limiting space between the two grooves of the upper limit seat and the lower limit seat is used to realize the rapid continuous crimping operation of the cable shell. The invention has the following shortcomings in practical use: after each pair of cable shells is crimped, workers need to push the cable feed. Due to the long length of the cable, manual pushing is quite laborious. Moreover, during the pushing process, the grinding block also needs to grind the burrs on both sides of the cable, which increases the resistance and further increases the difficulty of manual pushing. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a cable crimping machine for water conservancy and hydropower engineering construction, comprising a frame and a feeding mechanism. The feeding mechanism includes a movable block movably mounted on the front side of the frame. A hydraulic rod for driving the movable block to move back and forth is hinged to the frame. A through hole for the cable to pass through is opened in the middle of the movable block. Movable seats symmetrically distributed on the left and right sides of the through hole are slidably mounted inside the movable block. An arc-shaped toothed plate is rotatably connected to the side of the movable seat near the through hole. A torsion spring for driving the arc-shaped toothed plate to deflect forward is installed inside the movable seat.

[0005] The movable block is also equipped with a synchronization component that drives the two movable seats to move synchronously in opposite directions. A wedge plate is slidably installed on the rear side of the movable block to drive the right movable seat to move left and right. A guide rod is installed on the front side of the frame to push the wedge plate to move left and right. A locking component is installed on the left side of the movable block to lock the wedge plate.

[0006] In one possible implementation, a conveying roller located at the bottom of the through hole is rotatably mounted on the movable block, a return spring is fixedly connected between the side of the movable seat away from the through hole and the inner wall of the movable block, and guide rods are fixedly connected to both the left and right sides of the movable block, the guide rods being slidably connected to the frame in the front and back.

[0007] In one possible implementation, the movable seat is arc-shaped on the side near the through hole, a rotating shaft is rotatably mounted inside the movable seat, the side of the arc-shaped toothed plate away from the through hole is fixedly connected to the rotating shaft, the torsion spring is fitted onto the rotating shaft, the side of the arc-shaped toothed plate near the through hole is arc-shaped and has teeth, and the interior of the movable seat is reserved for the arc-shaped toothed plate to rotate backward.

[0008] In one possible implementation, the synchronization assembly includes a gear rotatably mounted on the inner wall of the top of the movable block, with racks meshing on both its front and rear sides, the movable seat being fixedly connected to the corresponding rack, and the right end of the wedge plate being fixedly connected to the rear rack.

[0009] In one possible implementation, the left end of the wedge plate has a guide groove, the left end of the guide groove is inclined forward and the right end is connected to the rear side of the wedge plate, the guide rod is aligned with the opening on the rear side of the guide groove, and the bottom of the wedge plate has a positioning hole.

[0010] In one possible implementation, a telescopic sleeve fitted over the left guide rod is fixedly installed on the front side of the frame. A support arm is fixedly installed on the telescopic section of the telescopic sleeve. A concave frame is fixedly connected to the front side of the top end of the support arm. The guide rod is fixedly connected between the two horizontal sections of the concave frame. When the movable block moves backward to abut against the front end of the telescopic sleeve, the wedge plate moves just between the two horizontal sections of the concave frame.

[0011] In one possible implementation, the locking assembly includes a movable plate that slides vertically on the left side of the movable block. A positioning pin is fixedly connected to the top of the movable plate and engages with a positioning hole. An inclined surface is provided on the rear side of the movable plate, with the rear end of the inclined surface tilting downward. A lifting unit for pushing the movable plate upward is also installed on the left side of the movable block.

[0012] In one possible implementation, the lifting unit includes a fixed plate fixedly mounted on the left side of the movable block, a movable column slidably mounted on the fixed plate, the top of the movable column being fixedly connected to the bottom of the movable plate, and a compression spring sleeved on the outside of the movable column being fixedly connected between the top of the fixed plate and the bottom of the movable plate.

[0013] In one possible implementation, a deburring mechanism is also included, comprising a movable frame located at the rear of the frame. The rear ends of the two guide rods slide through to the rear of the frame and are fixedly connected to the left and right ends of the movable frame, respectively. A second conveying roller is rotatably mounted on the bottom edge of the movable frame. A mounting seat symmetrically distributed on the top and bottom edges of the movable frame is movably mounted on both sides. Bolts for locking the mounting seats are installed on the movable frame. A circular file is detachably mounted between the two corresponding mounting seats.

[0014] The beneficial effects of this invention are:

[0015] 1. After the cable is crimped, the present invention uses a hydraulic rod to move a movable block backward. The movable block then moves the movable seat and the arc-shaped toothed plate backward together. Since the arc-shaped toothed plate is in a backward-biased state and the torsion spring provides elastic force for the arc-shaped toothed plate to rotate forward, when the arc-shaped toothed plate moves backward, it will clamp the surface of the cable. By using the arc-shaped toothed plate to move the cable backward, the cable can be automatically fed, eliminating the need for workers to move the cable backward. This makes it more convenient to use and allows for control of the length of each feeding to be consistent with the length of the crimping, ensuring a continuous connection at the crimping position. By using the arc-shaped toothed plate to clamp the cable during movement, it can prevent the cable from rotating during the feeding process, ensuring that the edges of the adjacent crimping positions are in a straight line, thus improving the crimping effect.

[0016] 2. This invention controls the movement of two movable seats in opposite directions through the cooperation of a synchronization component, a wedge plate, a guide rod, and a locking component. This allows the arc-shaped toothed plate to selectively clamp the cable. When the arc-shaped toothed plate clamps the cable and feeds backward, the locking component locks the wedge plate to prevent the movable seats from moving and improves the stability of the arc-shaped toothed plate when clamping the cable. When the arc-shaped toothed plate clamps the cable and feeds it into place, the concave frame pushes the movable plate downward, releasing the lock on the wedge plate. The guide rod pushes the wedge plate to the right, causing the two movable seats to separate from each other. This allows the arc-shaped toothed plate to loosen its clamping grip on the cable, facilitating the backward deflection of the arc-shaped toothed plate when the subsequent movable block moves forward.

[0028] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Please see Figure 1 - Figure 10A cable crimping machine for water conservancy and hydropower engineering construction includes a frame 1 and a feeding mechanism 2. The feeding mechanism 2 includes a movable block 21 movably installed on the front side of the frame 1. A hydraulic rod 22 for driving the movable block 21 to move back and forth is hinged on the frame 1. The front end of the telescopic section of the hydraulic rod 22 is hinged to the rear side of the movable block 21. A through hole for the cable to pass through is opened in the middle of the movable block 21. Movable seats 23 symmetrically distributed on the left and right sides of the through hole are slidably installed inside the movable block 21. An arc-shaped toothed plate 24 is rotatably connected to the side of the movable seat 23 near the through hole. A torsion spring 25 for driving the arc-shaped toothed plate 24 to deflect forward is installed inside the movable seat 23.

[0030] The movable block 21 is also equipped with a synchronization component 26 that drives the two movable seats 23 to move synchronously in opposite directions. A wedge plate 27 for driving the right movable seat 23 to move left and right is slidably installed on the rear side of the movable block 21. A guide rod 28 for pushing the wedge plate 27 to move left and right is installed on the front side of the frame 1. A locking component 29 for locking the wedge plate 27 is installed on the left side of the movable block 21.

[0031] In actual use, in the initial state, the hydraulic rod 22 drives the movable block 21 to move backward, so that the movable block 21 moves to a position close to the front side of the frame 1. At this time, the guide rod 28 pushes the wedge plate 27 to move to the right. The wedge plate 27 pushes the right movable seat 23 to move to the right. The right movable seat 23 drives the left movable seat 23 to move to the left synchronously through the synchronization component 26. The movable seat 23 drives the corresponding arc-shaped toothed plate 24 to move away from the through hole, so as to avoid affecting the insertion of the cable into the through hole and also to facilitate the removal of the crimped cable from the through hole.

[0032] After the cable's rear end passes through the through hole, it is placed between the upper and lower pressure heads. The cable housing is then fitted onto the outside of the cable, and the upper and lower pressure heads are used to crimp the cable housing. When the upper and lower pressure heads press the cable housing together, the hydraulic rod 22 pushes the movable block 21 forward, moving the movable block 21 to a position away from the front of the frame 1. When the movable block 21 moves forward, the guide rod 28 separates from the wedge plate 27. At this time, the wedge plate 27 drives the right movable seat 23 to move to the left. The right movable seat 23 drives the left movable seat 23 to move to the right synchronously through the synchronization component 26. The movable seat 23 drives the corresponding arc-shaped toothed plate 24 to move closer to the through hole, so that the arc-shaped toothed plate 24 moves forward along the surface of the cable. At this time, the arc-shaped toothed plate 24 will deflect backward under the push of the cable to prevent the arc-shaped toothed plate 24 from jamming the cable.

[0033] After the pressing is completed, the upper and lower pressing heads separate. At this time, the cable is supported by the movable block 21 to prevent the cable from falling with the lower pressing head. Then, the hydraulic rod 22 drives the movable block 21 to move backward again. The movable block 21 drives the movable seat 23 and the arc-shaped toothed plate 24 to move backward together. Since the arc-shaped toothed plate 24 is in a backward deflection state and the torsion spring 25 gives the arc-shaped toothed plate 24 a spring force to rotate forward, when the arc-shaped toothed plate 24 moves backward, it will clamp the surface of the cable. Using the arc-shaped toothed plate 24 to drive the cable to move backward, the cable can be automatically fed. There is no need for workers to carry the cable backward, which is more convenient to use. It can also control the length of each feeding to be consistent with the length of pressing, so that the connection of the pressing position is uninterrupted. By using the arc-shaped toothed plate 24 to clamp the cable for movement, it can prevent the cable from rotating during the feeding process, and ensure that the edges of the pressing positions at adjacent ends are in the same straight line, thus improving the pressing effect.

[0034] Please see Figure 1 - Figure 3 A conveying roller 211 located at the bottom of the through hole is rotatably mounted on the movable block 21. A return spring 212 is fixedly connected between the side of the movable seat 23 away from the through hole and the inner wall of the movable block 21. Guide rods 213 are fixedly connected to both the left and right sides of the movable block 21. The guide rods 213 are slidably connected to the frame 1.

[0035] In practical use, when the movable block 21 moves back and forth, it will drive the guide rod 213 to move back and forth as well. The frame 1 guides and limits the guide rod 213 to ensure the stability of the movable block 21 when it moves back and forth. When the movable block 21 moves along the cable, the conveyor roller 211 provides rolling support for the cable. The conveyor roller 211 can reduce the friction between the cable and the movable block 21 and improve the smoothness of the movement of the movable block 21. The return spring 212 provides elastic force to the movable seat 23 to move closer to the through hole, which facilitates the movement of the movable seat 23 towards the through hole.

[0036] Please see Figure 3 - Figure 5 The movable seat 23 has an arc-shaped side near the through hole to avoid affecting the cable passing through the through hole. The movable seat 23 has a rotating shaft 241 rotatably installed inside. The side of the arc-shaped toothed plate 24 away from the through hole is fixedly connected to the rotating shaft 241. The torsion spring 25 is fitted on the rotating shaft 241. The side of the arc-shaped toothed plate 24 near the through hole is arc-shaped and has teeth. The movable seat 23 has reserved space for the arc-shaped toothed plate 24 to rotate backward. When the movable seat 23 rotates forward to a horizontal position, the arc-shaped toothed plate 24 contacts the front inner wall of the movable seat 23.

[0037] In practical use, when the arc-shaped toothed plate 24 is not in contact with the cable, the torsion spring 25 provides elastic force to rotate the arc-shaped toothed plate 24 forward, enabling it to rotate forward to a horizontal state. When the arc-shaped toothed plate 24 comes into contact with the cable, as the movable block 21 drives the movable seat 23 to move forward, the arc-shaped toothed plate 24 will deflect backward under the push of the cable. At this time, the arc-shaped toothed plate 24 cannot clamp the cable. When the movable block 21 drives the movable seat 23 to move backward, the arc-shaped toothed plate 24 will tend to deflect forward under the push of the cable. However, during the rotation, the arc-shaped edge of the arc-shaped toothed plate 24 will move closer to the center line of the through hole, causing the arc-shaped toothed plate 24 to gradually clamp the cable, making the arc-shaped toothed plate 24 move backward with the cable, which facilitates the feeding of the cable.

[0038] Please see Figure 3 and Figure 4 The synchronization component 26 includes a gear 261 rotatably mounted on the inner wall of the top of the movable block 21. The gear 261 is meshed with racks 262 on both the front and rear sides. The movable seat 23 is fixedly connected to the corresponding rack 262. The right end of the wedge plate 27 is fixedly connected to the rack 262 behind it.

[0039] In practical use, when the right movable seat 23 moves left and right, the right movable seat 23 drives the rear rack 262 to move together. The rear rack 262 drives the front rack 262 to move synchronously in the opposite direction through the gear 261. The front rack 262 drives the left movable seat 23 to move, which enables the left and right movable seats 23 to move synchronously in the opposite direction, making it convenient to adjust the left and right arc-shaped toothed plates 24 at the same time.

[0040] Please see Figure 3 , Figure 4 and Figure 8 The left end of the wedge plate 27 is provided with a guide groove 271. The left end of the guide groove 271 is inclined forward and the right end is connected to the rear side of the wedge plate 27. The guide rod 28 is aligned with the opening on the rear side of the guide groove 271. The bottom of the wedge plate 27 is provided with a positioning hole 272.

[0041] In practical use, when the movable block 21 moves backward, the wedge plate 27 moves backward along with the movable block 21. When the wedge plate 27 moves to the guide rod 28, the guide rod 28 just enters the guide groove 271. As the wedge plate 27 continues to move backward, the guide rod 28 slides along the guide groove 271. The guide rod 28 pushes the wedge plate 27 to move to the right. The wedge plate 27 drives the right movable seat 23 to move to the right through the rack 262 on the rear side, so that the arc-shaped toothed plate 24 releases its clamp on the cable, making it easier for the movable block 21 to drive the arc-shaped toothed plate 24 to move forward.

[0042] Please see Figure 1 , Figure 6 and Figure 9A telescopic sleeve 281 is fixedly installed on the front side of the frame 1 and sleeved on the outside of the left guide rod 213. A support arm 282 is fixedly installed on the telescopic section of the telescopic sleeve 281. A concave frame 283 is fixedly connected to the front side of the top of the support arm 282. The guide rod 28 is fixedly connected between the two horizontal sections of the concave frame 283. When the movable block 21 moves backward to abut against the front end of the telescopic sleeve 281, the wedge plate 27 just moves between the two horizontal sections of the concave frame 283.

[0043] Please see Figure 1 , Figure 3 , Figure 7 and Figure 9 The locking assembly 29 includes a movable plate 291 that is slidably mounted on the left side of the movable block 21. A positioning pin 292 is fixedly connected to the top of the movable plate 291. The positioning pin 292 is inserted into the positioning hole 272. A slope is provided on the rear side of the movable plate 291. The rear end of the slope is inclined downward. A lifting unit 293 for pushing the movable plate 291 upward is also installed on the left side of the movable block 21.

[0044] Please see Figure 1 , Figure 3 , Figure 6 , Figure 7 and Figure 9 The lifting unit 293 includes a fixed plate 2931 fixedly installed on the left side of the movable block 21. A movable column 2932 is slidably installed on the fixed plate 2931. The top of the movable column 2932 is fixedly connected to the bottom of the movable plate 291. A compression spring 2933 sleeved on the outside of the movable column 2932 is fixedly connected between the top of the fixed plate 2931 and the bottom of the movable plate 291.

[0045] In practical use, when the wedge plate 27 and the guide rod 28 are separated, the positioning pin 292 is inserted into the positioning hole 272. The positioning pin 292 locks the wedge plate 27, which can prevent the wedge plate 27 from moving left and right, prevent the movable seat 23 from moving left and right, and improve the stability of the arc-shaped toothed plate 24 for clamping the cable.

[0046] When the movable block 21 moves the guide groove 271 backward to engage with the guide rod 28, the horizontal section at the bottom of the concave frame 283 will first contact the inclined surface at the rear of the movable plate 291. The horizontal section at the bottom of the concave frame 283 pushes the movable plate 291 downward. The movable plate 291 drives the positioning pin 292 downward. When the opening at the rear end of the guide groove 271 moves to engage with the guide rod 28, the positioning pin 292 just separates from the positioning hole 272, releasing the lock on the wedge plate 27. This makes it easier for the guide rod 28 to push the wedge plate 27 to move to the right relative to the movable block 21. The wedge plate 27 drives the two movable seats 23 to move away from each other, releasing the arc-shaped toothed plate 24 from fixing the cable.

[0047] When the movable block 21 moves backward and contacts the front end of the telescopic sleeve 281, the movable block 21 can no longer move backward. The telescopic sleeve 281 limits the distance that the movable block 21 can move forward and backward, so that the length of the cable is consistent each time it is fed. By adjusting the telescopic length of the telescopic sleeve 281, the length of the cable can be adjusted to meet the pressing needs of different cables.

[0048] When the movable block 21 moves the wedge plate 27 forward, the guide rod 28 slides backward along the guide groove 271. At this time, the guide rod 28 guides the wedge plate 27 to move to the left relative to the movable block 21. The wedge plate 27 drives the two movable seats 23 to move closer to each other, so that the movable seats 23 can re-contact the cable. When the guide rod 28 separates from the guide groove 271, the positioning hole 272 moves just above the positioning pin 292. At this time, the compression spring 2933 moves the movable plate 291 upward, so that the movable plate 291 drives the positioning pin 292 to be inserted into the positioning hole 272, and the wedge plate 27 is locked again.

[0049] Please see Figure 2 and Figure 10 It also includes a deburring mechanism 3, which includes a movable frame 31 located at the rear of the frame 1. The rear ends of two guide rods 213 slide through to the rear of the frame 1 and are fixedly connected to the left and right ends of the movable frame 31 respectively. A conveying roller 32 is rotatably mounted on the bottom edge of the movable frame 31. The top and bottom edges of the movable frame 31 are movably mounted with symmetrically distributed mounting seats 33. Bolts for locking the mounting seats 33 are installed on the movable frame 31. A circular file 34 is detachably mounted between the two corresponding mounting seats 33.

[0050] In practical use, the second conveyor roller 32 can support the rear end of the cable to prevent it from sagging. By adjusting the distance between the two mounting seats 33, the circular file 34 is brought into contact with the edges of the cable shell on both sides. When the cable shell is burred, the moving block 21 moves forward, which in turn moves the guide rod 213 forward. The guide rod 213 moves the moving frame 31 forward, which in turn moves the circular file 34 forward. The circular file 34 is used to polish the burrs on the edges of the cable shell without the need for manual polishing. Moreover, the circular file 34 is driven by the hydraulic rod 22, so there is no need to manually push the cable, which saves more effort.
