[0048] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0049] A portable cable cutting and crimping device, such as Figure 1 , Figure 6 As shown, it includes a connected base unit 1 and a movable bracket unit 2, a lifting unit 3 connected to the movable bracket unit 2 through a micro-adjustment unit 4, and a cut-off unit 5 or a crimping unit 6 can be replaced at the bottom of the lifting unit 3. The problems of difficult cut-off and difficult crimping of joints when laying cables in engineering projects are solved. The device can achieve "one machine for two purposes". Through the rapid replacement of tools and molds, it can meet the dual functions of cable cut-off and cable head crimping. The cable head is pressed and formed at one time, with high processing and production efficiency, which can effectively reduce costs.

[0050] Specifically, in order to achieve the purpose of switching the cable cutting and cable head pressing functions by replacing only a few parts of the device, such as the cutting unit 5 or the crimping unit 6, more parts should be shared parts, among which the base unit 1 and the movable bracket unit 2 are important shared parts of the device.

[0051] Specifically, the device has a wide range of applications and can be used with cables ranging from 16mm² to 300mm².

[0052] Specifically, if the cable needs to be connected to other devices or systems after cutting, crimping the cable head becomes a necessary step. Crimping is a way of connecting wires and terminals during cable assembly. By applying a certain mechanical external force, the wires and terminals are tightly joined, thereby achieving the purpose of electrical conduction or firm joining. Good crimping terminals can reduce resistance and reduce copper wire oxidation at the crimping point, and have various excellent properties such as firm tightness and good conductivity. After cutting the cable, the utility model replaces the cutting unit 5 with the crimping unit 6 to crimp the cable head, which is very convenient.

[0053] Based on the above implementation, as a preferred implementation, Figure 3 As shown, the base unit 1 includes a base 11 for placing the cable, the upper surface of the base 11 is provided with a make way groove 12 for inserting the cutting unit 5, the base 11 is provided with an ear plate 13, the movable bracket unit 2 is plugged into the ear plate 13 and connected by a bolt group 14, and the upper surface of the base 11 is arc-shaped to fit the curvature of the cable to prevent random movement and facilitate cutting.

[0054] Specifically, when the cut-off unit 5 or the crimping unit 6 needs to be replaced, it is only necessary to unscrew the bolt group 14, separate the base unit 1 and the movable bracket unit 2, and then connect the cut-off unit 5 or the crimping unit 6 with the movable bracket unit 2, and then plug the base unit 1 and the movable bracket unit 2 together, tighten the bolt group, and the installation is successful, ensuring that the base unit 1 and the movable bracket unit 2 can be quickly disassembled and assembled, which is convenient, fast and easy to operate.

[0055] Based on the above implementation, as a preferred implementation, Figure 4 As shown, the movable bracket unit 2 includes a vertically arranged support column 1 21 and a support column 22. The inner side surface of the support column 1 21 is provided with a slide groove 23 for the cutting unit 5 or the crimping unit 6 to move. A limiting rod 24 is provided in the slide groove 23. The cutting unit 5 or the crimping unit 6 is limited by the limiting rod 24 and slides along the limiting rod 24. The support column 22 is provided with a hole 25 for the fine-adjustment unit 4 to pass through.

[0056] Based on the above implementation, as a preferred implementation, Figure 3 As shown, a limiting rod 15 is provided on the base 11, and the truncation unit 5 or the crimping unit 6 is limited by the limiting rod 15 and slides along the limiting rod 15. The end of the limiting rod 15 is a threaded end, and the threaded end passes through the hole 26 on the support column 22 and is threadedly matched with the nut 16.

[0057] Specifically, the movable bracket unit 2 should be ensured to be firm and stable during the cable cutting and cable head pressing process. This is achieved by adding the limit rod 15, the two ends of which are respectively connected to the base 11 and the support column 21, and the upper winged nut 16 is used for quick locking. At the same time, it can be adjusted following the fine-tuning unit 4.

[0058] Based on the above implementation, as a preferred implementation, Figure 1 , Figure 2 As shown, the lifting unit 3 includes a spring 31 connected to the bottom surface of the support column 22, the other end of the spring 31 is connected to the cut-off unit 5 or the crimping unit 6, a hydraulic jack 32 is connected between the support column 22 and the cut-off unit 5 or the crimping unit 6, and the top end of the hydraulic jack 32 is connected to the fine-adjustment unit 4.

[0059] Specifically, springs 31 are provided on both sides of the hydraulic jack 32. The hydraulic jack 32 presses downward, that is, pushes the cutting unit 5 or the crimping unit 6 downward to cut or crimp the cable. The spring 31 pulls the cutting unit 5 or the crimping unit 6 upward through elastic force to separate it from the cable.

[0060] Specifically, the hydraulic jack 32 may adopt a manual hydraulic pump or an electric hydraulic pump.

[0061] Specifically, an oil pipe interface 33 is provided on the hydraulic jack 32 .

[0062] Based on the above implementation, as a preferred implementation, Figure 2 As shown, the fine adjustment unit 4 includes a screw rod 41, one end of which is connected to the hydraulic jack 32, and the other end of the screw rod 41 passes through the hole 1 25 and is threadedly engaged with the nut 2 42, and the nut 2 42 is pressed on the support column 1 21.

[0063] Specifically, the height of the support column 22 is based on the stroke of the lifting unit 3. Considering that the outer diameter of the 300mm² cable is about 90mm, the stroke of the hydraulic jack 32 can be slightly larger. The stroke of this device is 100mm. The height of the movable bracket unit 2 should be able to meet the full stroke operation of the hydraulic jack 32. At the same time, considering the error problem, a fine-adjustment unit 4 is introduced to cooperate in adjusting the stroke of the lifting unit 3.

[0064] Preferably, the hydraulic jack 32 should be selected taking into account lightness, working stroke and lifting capacity. This device uses a hydraulic jack with a lifting capacity of 10 tons. At the same time, both a manual hydraulic pump and an electric hydraulic pump can be used.

[0065] Based on the above implementation, as a preferred implementation, Figure 5 As shown, the cutting unit 5 includes a tool 52 connected to a force-bearing seat 51, and a hanging ring 53 for connecting the spring 31 is provided on the force-bearing seat 51. The two ends of the force-bearing seat 51 are respectively provided with a hole 54 plugged into the limit rod 24 and a hole 55 clamped into the limit rod 215, and the tool 52 is plugged into and matched with the clearance groove 12.

[0066] Specifically, the cutter 52 should be made of high-strength alloy steel, and its pressure-bearing capacity should not be lower than the compressive strength of copper to ensure the durability of the cutting edge. To prevent a short service life, the cutting edge of the cutter 52 is blunt.

[0067] Specifically, the number and position of the hanging rings 53 on the force bearing seat 51 correspond to the springs 31 one by one to maintain balance.

[0068] Based on the above embodiment, as a preferred embodiment, the support column 22 is detachably connected with a safety shielding plate 7. To cooperate with the cable cutting work, a semicircular safety shielding plate 7 should be set on both sides of the cutter to ensure safety during cutting.

[0069] Specifically, a bolt is provided on the support column 1 21 , and the bolt passes through the hole 3 on the safety shielding plate 7 and is then fixed by a nut.

[0070] Based on the above implementation, as a preferred implementation, Figure 6-Figure 9 As shown, the crimping unit 6 includes a mold connected to the lower part of the force-bearing seat 61, and the mold includes an upper mold head 62 and a lower mold head 63 that are plug-in compatible. The upper mold head 62 is connected to the force-bearing seat 61 through a connecting rod 64, and the lower mold head 63 is connected to the supplementary base 66 through a positioning member 65 arranged at the bottom. The bottom of the supplementary base 66 is provided with a positioning piece 67 that is plug-in compatible with the give way groove 12. The upper mold head 62 and the lower mold head 63 are both provided with a pressing groove 60 for clamping the cable.

[0071] Specifically, the pressing die head is a key point in the manufacture of this device, and also an innovative point. According to the cable model, a matching die head is manufactured, with three groups of pressing grooves as a set, two of which have the same shape, and the other group of pressing grooves are 30 degrees offset from the two groups. They are fixed on the positioning plates of the upper die head 62 and the lower die head 63 in sequence. The shape-displaced pressing grooves should be placed in the middle, and the spacing should meet the pressing requirements, generally 10mm is appropriate. In addition, the lower die head 63 is provided with limiting baffles on both sides of the pressing groove to avoid left and right misalignment during the upper die head 62 moving down.

[0072] Specifically, the positioning member 65 includes a positioning column, and a positioning hole is provided on the top surface of the supplementary base 66. The positioning column is plugged into the positioning hole to play a positioning role.

[0073] Based on the above implementation, as a preferred implementation, Figure 8 As shown, the force-bearing seat 61 is provided with a hanging ring 68 for connecting the spring 31, and the two ends of the force-bearing seat 61 are respectively provided with a hole 69 for plugging with the limit rod 24 and a hole 70 for clamping with the limit rod 15.

[0074] Specifically, the force base of the device is divided into two types, namely, the force base 1 51 is used for cable cutting, and the force base 2 61 is used for cable head crimping. The force base should take displacement into consideration. The device adopts the limit rod 1 24, the limit rod 2 15, and the force base to cooperate and control to achieve the limit target. Two symmetrical hanging rings are set on the upper part of the force base. The hydraulic jack presses downward, that is, pushes the cut-off unit 5 or the crimping unit 6 downward to cut or crimp the cable. The spring pulls the cut-off unit 5 or the crimping unit 6 upward through elastic force to separate from the cable.

[0075] The method of using the utility model is as follows:

[0076] 1. Insert the cut-off unit 5 into the movable bracket unit 2, and then install the base unit 1;

[0077] 2. Place the cable on the curved surface of the base 11, and the hydraulic jack 32 pushes the cutter 52 downward. When the cutter 52 is inserted into the clearance groove 12, the cable is cut off;

[0078] 3. The spring 31 drives the cutting unit 5 to lift up;

[0079] 4. Replace the crimping unit 6;

[0080] 5. Place the cable end to be crimped into the crimping groove 60 of the lower die pressing head 63. The hydraulic jack 32 pushes the upper die pressing head 62 downward. When the upper die pressing head 62 and the lower die pressing head 63 merge, the cable is crimped.

[0081] 6. The spring 31 drives the crimping unit 6 to lift up.

[0082] The utility model solves the problems of difficult cable cutting and difficult joint crimping during cable laying in engineering projects. The device can achieve "one machine with two uses".
