Description

Technical Field

[0001] This utility model relates to the technical field of wire and cable production equipment, and discloses a trimming knife for pre-branched cable production. Background Technology

[0002] Pre-branched cables are cables in which branches are prefabricated according to the user's design drawings during the production of main cables. They are a new technology product in recent years. Compared with the original technology, they have excellent shock resistance, airtightness and waterproofness. They are widely used in places with high requirements for power supply safety, such as vertical power supply in electrical shafts of high-rise buildings, residential buildings, commercial buildings, hotels and hospitals. They are also suitable for power supply systems in tunnels, airports, bridges and highways.

[0003] The production process of pre-branched cables includes multiple steps such as crimping, injection molding, and finishing. Due to the characteristics of the pre-branched cable production process, the automation level is low, and most of the processes are completed manually. The main cable and branch cable used to produce pre-branched cables are not perfectly round. In addition, due to the presence of the parting surface between the moving mold and the stationary mold, some flash and excess material will remain at the cable inlet and outlet and on the parting surface between the moving mold and the stationary mold during the molding process of the pre-branched joint.

[0004] Because the surface of the pre-branch joint is irregular, the trimming surface where the flash is located can be flat, curved, or right-angled. It is difficult to control the cutting depth and angle when cleaning the flash with ordinary tools, which can easily cause scratches to the joint and personnel. At the same time, the trimming flash has uneven cutting allowance, which affects the overall surface quality of the pre-branch joint. The blades used are commonly used blades on the market, and the consumables are cheap and easy to obtain. Utility Model Content

[0005] In view of this, this application provides a trimming knife for pre-branched cable production, which solves the problem that due to the irregular surface of the pre-branched joint itself, the trimming surface where the flash is located has various conditions such as flat surface, curved surface and right angle surface, it is difficult to control the cutting depth and cutting angle when using ordinary tools to clean the flash, which can easily cause scratches to the joint and personnel, uneven cutting allowance, and reduced overall surface quality of the pre-branched joint.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A trimming tool for pre-branched cable production, comprising:

[0008] Tool holder 1;

[0009] Two support rods 4 are set at the front end of the tool holder 1, one in front of the other, and the two support rods 4 are connected to the tool holder 1 at an adjustable angle.

[0010] The tool holder 7 is mounted on the tool holder 1 and located between the two support rods 4;

[0011] Ear seat 9 is mounted on the knife holder 7 at an adjustable angle;

[0012] The blade holder 8 is mounted on the ear seat 9;

[0013] Blade 13 is mounted on the tool holder 8.

[0014] One type of trimming knife for pre-branched cable production has a handle 2 at the tail of the knife bar 1.

[0015] One type of trimming knife for pre-branched cable production has a support 3 at the connection between the support rod 4 and the knife bar 1, and the support rod 4 and the support 3 are connected to each other by a locking screw 5.

[0016] One type of trimming knife for pre-branched cable production has a ball bearing 6 at the bottom of the support rod 4.

[0017] One type of trimming knife for pre-branched cable production has an ear seat 9 and a knife seat 7 connected to each other by a locking screw 10.

[0018] One type of trimming knife for pre-branched cable production has a blade groove 11 inside the ear seat 9, and a clamping piece 12 inside the blade groove 11, which clamps the blade 13.

[0019] In summary, the present application is described in detail below compared with the prior art:

[0020] This invention allows for adjustment of the cutting depth and angle by adjusting the angle between each support rod and the support base, thus meeting the needs of different finishing surfaces such as planes, curved surfaces, and right-angled surfaces. At the same time, the cutting angle can be adjusted by adjusting the angle between the blade and the tool holder to meet the cutting needs of different materials. Ball bearings are installed at the ends of the support rods to prevent scratches on the finishing surface during the cutting process, resulting in smooth and labor-saving cutting, uniform cutting allowance, and smooth cut.

[0021] This invention solves the problem that, due to the irregular surface of the pre-branch joint itself, the trimming surface where the flash is located can have various conditions such as flat, curved, and right-angled surfaces. It is difficult to control the cutting depth and cutting angle when cleaning flash with ordinary tools, which can easily cause scratches to the joint and personnel, uneven cutting allowance, and reduced overall surface quality of the pre-branch joint.
