Description

Technical Field

[0001] This utility model relates to a cable copper crimping end crimping device. Background Technology

[0002] In the vehicle's electrical system, the power supply for high-current devices such as batteries, oil-cooled generators, and hydraulic motors requires the use of large-diameter wires to transmit electrical signals. These power lines are generally composed of wires and copper crimp terminals. The connection between the copper crimp terminals and the wires is achieved through crimping. Therefore, the reliability of the crimping between the wires and the copper crimp terminals directly affects the transmission of electrical signals.

[0003] For a long time, the factory has used manual hydraulic crimping pliers to crimp the ends of thick cables. The manual hydraulic pliers are equipped with 16 mm... 2 25 mm 2 35mm 2 During the production process, operators select the appropriate hexagonal crimping die according to the wire diameter and install it in the slot of the manual hydraulic crimping tool. The operator manually operates the hydraulic crimping tool handle to the maximum crimping position. Inconsistent operating force from the operator leads to inconsistent crimping degrees, resulting in over-crimping or under-crimping at the ends. This causes abnormal phenomena such as loose wire ends and wire damage, leading to intermittent electrical performance and other abnormal outputs, which seriously affects circuit characteristics. Moreover, this manual crimping method is inefficient, labor-intensive, and poses certain personal safety hazards. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a simple, safe and reliable cable copper crimping end crimping device.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is: a cable copper crimping end crimping device, including an upper mold base and a lower mold base. The top of the upper mold base is fixedly connected to the pressure rod of the crimping equipment. The bottom of the upper mold base is provided with a first slot for installing the upper half of the hexagonal crimping mold. The bottom of the lower mold base is fixedly set on the worktable of the crimping equipment. The top of the lower mold base is provided with a second slot for installing the lower half of the hexagonal crimping mold.

[0006] In the aforementioned cable copper crimping end crimping device, a baffle for positioning the protruding end is fixed to the outer side of the upper surface of the lower mold base by a first screw.

[0007] In the aforementioned cable copper crimping end crimping device, the lower half of the hexagonal crimping mold is installed in the second slot of the lower mold base by a second screw.

[0008] In the aforementioned cable copper crimping end crimping device, the lower mold base is fixed to the worktable of the crimping equipment by a third screw.

[0009] The above-mentioned cable copper crimping end crimping device has the upper half of the hexagonal crimping mold installed in the first slot of the upper mold base by the fourth screw.

[0010] In the aforementioned cable copper crimping end crimping device, the upper mold base is fixed to the crimping rod of the crimping equipment by a fifth screw.

[0011] The above-mentioned cable copper crimping end crimping device has the upper half of the hexagonal crimping mold and the lower half of the hexagonal crimping mold flush and aligned.

[0012] The beneficial effects of this utility model are as follows: This utility model utilizes the existing crimping equipment and hexagonal crimping mold in the factory to install the upper and lower mold bases of the end crimping device on the crimping equipment to achieve the connection between the hexagonal crimping mold and the crimping equipment. By setting a standard pressure value, semi-automatic crimping of cable ends is achieved. It adopts a combination of mechanical and electrical methods, which is simple and quick to install, simple and reliable to operate, and has the advantages of low cost, safety, high efficiency, simple operation, and convenience.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1-Figure 5As shown, a cable copper crimping end crimping device includes an upper mold base 1 and a lower mold base 2. The top of the upper mold base 1 is fixedly connected to the pressure rod of the crimping equipment by a fifth screw 3. The bottom of the upper mold base 1 has a first slot 5 for mounting the upper half of a hexagonal crimping mold 4 in the middle. The upper half of the hexagonal crimping mold 4 is mounted in the first slot 5 of the upper mold base 1 by a fourth screw 6. The bottom of the lower mold base 2 is fixedly mounted on the worktable of the crimping equipment by a third screw. The top of the lower mold base 2 has a second slot 7 for mounting the lower half of the hexagonal crimping mold 4 in the middle. The lower half of the hexagonal crimping mold 4 is mounted in the second slot 7 of the lower mold base 2 by a second screw 9. The upper half and lower half of the hexagonal crimping mold 4 are flush and fit together.

[0020] like Figure 5 As shown, a baffle 8 is fixed to the outer side of the upper surface of the lower mold base 2 by a first screw. The baffle 8 is used to position the end protrusion head to ensure that the force points of each end are consistent and to ensure the consistency of the pressing position.

[0021] The working process of this utility model is as follows: First, use two first screws to install the baffle 8 on the lower mold base 2. Then, use two second screws to install the upper part of the hexagonal crimping mold 4, which corresponds to the specifications of the copper crimping end, into the second slot 7 of the lower mold base 2. Then, use four third screws to fix the lower mold base 2 to the worktable of the crimping equipment through the four waist-shaped slots of the lower mold base 2.

[0022] Using the same method, the lower half of the hexagonal pressing mold 4 is installed in the first slot 5 of the upper mold base 1 using two fourth screws 6. Then, the upper mold base 1 is fixed on the pressing rod of the pressing equipment using four fifth screws 3. Then, a trial mold correction is performed. The upper half and the lower half of the hexagonal pressing mold 4 must be flush and fit together before pressing can be performed.

[0023] Set the crimping parameters such as pressure and crimping speed on the crimping equipment display screen, then press the start button of the crimping equipment. The pressure rod on the crimping equipment will automatically move down to apply pressure to the copper crimping end, realizing automatic crimping of the copper crimping end.
