Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, specifically to a cable crimping tool. Background Technology

[0002] Cable joint fabrication is a crucial step in cable installation. Due to their concealed location, cable joints are often the weakest link in cable operation and maintenance, leading to increasingly serious quality problems. The cable joint fabrication process is complex, with crimping the cable conductor being the most critical step. Loose crimps and excessive contact resistance can result in substandard cable joints. Currently, conductor crimping is primarily performed by workers using simple tools such as manual crimping pliers; this is inefficient and yields inconsistent quality. Over time, excessive heat at the crimped area can cause localized insulation damage, threatening the safe use of the cable. Utility Model Content

Crimping grooves are respectively provided between the opposite faces of the upper die and the lower die. The two crimping grooves close to form a polygonal wire hole. A cable and a sleeve are threaded through the opposite sides of the polygonal wire hole or on one side of the polygonal wire hole, and the crimping part of the sleeve and the inner cable is pressed to match the shape of the polygonal wire hole, thereby forming an integrated cable structure.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] like Figure 1 and Figure 2 As shown, this utility model provides a cable crimping tool for crimping shielded cables. It includes an upper die and a lower die that move towards or away from each other. Crimping grooves 41 are respectively provided between the opposite faces of the upper and lower dies. The two crimping grooves 41 close to form a polygonal wire-passing hole. In this embodiment, as shown... Figure 2 The tool is designed with a hexagonal wire-passing hole, consisting of two symmetrically arranged trapezoidal grooves. Cables and sleeves (such as shielding layers or connectors) are sequentially threaded outwards along the central axis of the polygonal wire-passing hole on opposite sides or one side of the hole. The crimping structure of the sleeves and the inner cable is pressed to match the shape of the polygonal wire-passing hole, thus forming an integrated cable structure. This tool effectively solves the problems of low efficiency and unreliable quality in traditional manual wire crimping, avoids incomplete crimping during the process, reduces rework and scrap rates, and saves production costs.

[0014] In this embodiment, as Figure 1 and Figure 2 As shown, the upper die includes a die handle 1, an upper connecting plate 2, and an upper template 3. One end of the die handle 1 is connected to the pressure head of the stamping machine. The upper connecting plate 2 is installed on the end of the die handle 1 away from the pressure head of the stamping machine. The upper template 3 is installed on the side of the upper connecting plate 2 away from the die handle 1, and a pressure groove 41 is provided at the end near the lower die. The lower die includes a lower connecting plate 9 and a lower template 8. The lower connecting plate 9 is detachably installed on the bed of the stamping machine. The lower template 8 is installed on the end of the lower connecting plate 9 away from the bed of the stamping machine, and a pressure groove 41 is provided at the end near the upper die. Specifically, a pressure die 4 is detachably installed between the opposite surfaces of the upper and lower dies, such as... Figure 3 As shown, the creasing groove 41 is formed on the creasing mold 4. Wherein, as... Figure 2 As shown, multiple countersunk bolt holes penetrating the die 4 are respectively opened on the opposite sides of the upper template 3 and the lower template 8. A set of socket head cap screws 10 and washers 11 are arranged in each countersunk bolt hole. The socket head cap screws 10 pass through the washers 11 and the countersunk bolt holes on the upper template 3 / lower template 8 in sequence and are threaded to the die 4. This facilitates the replacement of die 4 with different shapes and sizes for creasing processing and improves the die changing efficiency of the stamping machine. The washers 11 are also provided to prevent the socket head cap screws 10 from stripping.

[0015] Furthermore, such as Figure 1 and Figure 2 As shown, several sets of guide components are provided between the opposing surfaces of the upper and lower molds. The guide components include guide sleeves 5 and guide posts 6 that are slidably connected to each other. The ends of the guide sleeves 5 and guide posts 6 that are far apart from each other are fixedly installed on the upper and lower molds. After the upper and lower molds are closed, the guide posts 6 are inserted into the guide sleeves 5. When the upper and lower molds are demolded, the guide posts 6 are gradually pulled out from the guide sleeves 5 or slidably connected to them. Thus, precise positioning is achieved through the guide components during the mold closing process, ensuring the crimping accuracy of the cable. If alignment misalignment occurs during the mold closing process due to installation errors, the guide posts 6 cannot be inserted into the guide sleeves 5. In this case, it can prevent the crimping of the cable from being damaged by the closing of the upper and lower molds.

[0016] Furthermore, such as Figure 1 As shown, a baffle 7 is fixedly installed on the upper mold and / or the lower mold. One end of the baffle 7 extends along the direction of mutual movement of the upper mold and the lower mold to be flush with or beyond the opening side of the wire pressing groove 41, and has a wire threading port. The axis of the wire threading port is perpendicular to the center line of the polygonal wire threading hole, which can limit and block the operator's hand during the wire threading process, and achieve the protection effect.
