Description

Technical Field

[0001] This invention relates to the field of cable metal sheath welding technology, and in particular to an adjustable horn mold and cable metal sheath production line. Background Technology

[0002] In cable manufacturing, the conductor's outer surface consists of multiple coaxial layered structures, typically including insulation, shielding, and a metal sheath. While some layers are formed by extrusion, the metal sheath is usually formed using longitudinal wrapping. Existing technologies commonly use aluminum-plastic composite tape, aluminum tape, and copper tape for longitudinal wrapping. The process involves passing the metal tape through a series of horn-shaped molds to gradually wind it up, then shaping and wrapping it around the cable core. The seams of the metal tape are then welded, and finally, the cable wrapped with the metal sheath is wound up. However, the existing horn-shaped molds have fixed support heights, and the shape and size of the shaping parts are also fixed. They cannot be directly adjusted to accommodate cables of different diameters. Each horn-shaped mold must be replaced before production, depending on the cable diameter, which is time-consuming, labor-intensive, and inefficient.

[0003] Therefore, those skilled in the art are dedicated to developing an adjustable horn mold and cable metal sheath production line. Summary of the Invention

[0004] In view of the above-mentioned deficiencies of the prior art, the present invention discloses an adjustable horn mold and cable metal sheath production line. The technical problem to be solved is to provide an adjustable horn mold and cable metal sheath production line.

[0005] To achieve the above objectives, the present invention provides an adjustable horn mold, including a height-adjustable bracket, a mold support ring connected to the bracket, and a plurality of adjusting rods evenly arranged radially on the mold support ring. An arc-shaped support block is fixed to one end of the adjusting rod facing the center of the mold support ring, and the adjusting rod can move radially.

[0006] Preferably, the number of the arc-shaped support blocks is 6 to 12, and several of the arc-shaped support blocks can be arranged inward to form a hollow cylinder.

[0007] Preferably, the mold support ring has a radially extending support through hole, and the outer surface of the mold support ring also has a fixing ring coaxial with the support through hole. The adjusting rod is slidably engaged with both the fixing ring and the support through hole. The adjusting rod has a positioning through hole, and the fixing ring is fitted with a positioning pin that engages with the positioning through hole. After the adjusting rod is moved within the support through hole to determine its position, it is fixed by the positioning pin.

[0008] Preferably, the bracket includes symmetrically arranged support rods hinged to the mold support ring. Each support rod has a sliding rod hinged to its bottom end, and two sliding rods are installed within the grooved base. The sliding rods can move within the grooved base or be fixed within it. The sliding rods can be configured to have significant friction between them, allowing for positioning based on this friction. Alternatively, a slot can be provided within the grooved base, and a positioning block can be attached to the sliding rod for fixation. A hole can also be drilled, and a pin can be used to fix the sliding rod. Other fixing methods are also possible.

[0009] The present invention also provides a cable metal sheath production line, including the adjustable horn mold as described above.

[0010] The present invention provides a cable metal sheath production line, which further includes an argon arc welding corrugating machine and a gantry winding machine. The cable, after being wrapped with a metal sheath by the adjustable horn mold, enters the argon arc welding corrugating machine, and the gantry winding machine is used to wind up the welded cable.

[0011] Preferably, the gantry-type cable take-up machine includes a support shaft mounted on a gantry frame, one end of the support shaft is connected to an extension shaft, the extension shaft is hinged to a position sensing arm, the position sensing arm is used to sense the position of the cable, the gantry-type cable take-up machine is provided with a controller that is signal-connected to the position sensing arm, and the controller is also electrically connected to a motor that drives the support shaft to rotate.

[0012] Preferably, bearings are provided between the extension shaft and the support shaft, and between the support shaft and the gantry frame.

[0013] Preferably, the position sensing arm includes a vertically connected rotating rod and a sensing rod, the rotating rod being hinged to the extension shaft, and the sensing rod being equipped with a position sensor that is signal-connected to the controller.

[0014] In existing cable take-up frames, because the tension of the take-up frame remains constant, the weight of the spool increases after the cable is loaded, and the take-up speed is less than the output speed of the argon arc welding and corrugating machine production line, making the cable prone to dragging on the ground and causing abrasions. In this invention, a position sensing arm is added to the support shaft. When the cable's linear speed is greater than the output speed of the argon arc welding and corrugating machine, the cable's height above the ground increases. When the sensing arm moves from point P to point P1 under the influence of the cable, a trigger signal is sent to the motor at the take-up point, reducing the motor speed. The motor speed is then adjusted based on the cable outer diameter and cable pitch values ​​input on the gantry-type take-up machine. When the cable's linear speed is less than the output speed of the argon arc welding and corrugating machine, when the sensing arm moves from point P to point P2 under the influence of the cable, a trigger signal is sent to the motor at the take-up point, increasing the motor speed. The motor speed is then adjusted based on the cable outer diameter and cable pitch values ​​input on the gantry-type take-up machine. This avoids the problems of tensile damage to the cable or abrasions caused by cable friction against the ground.

[0015] The beneficial effects of this invention are:

[0016] By incorporating a height-adjustable bracket, the height of the entire horn mold can be adjusted according to the cable diameter. Simultaneously, the structure of the mold support ring allows for radial movement of the adjusting rod, thereby adjusting the diameter of the inner circle formed by the arc-shaped support block to accommodate different specifications of metal sheaths required for cables of varying diameters. Therefore, the height of the horn mold and the shape and size of the shaping section are all adjustable. For cables of different diameters, direct adjustment is possible, eliminating the need to replace each horn mold based on cable diameter even when producing different products. This saves time and labor, improves production efficiency, reduces the demand and inventory of horn molds, and lowers production costs. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that in the description of the present invention, terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific manner. Therefore, they should not be construed as limitations on the present invention. Terms such as "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] like Figure 1 As shown, the present invention provides an adjustable horn mold 1, including a height-adjustable bracket 11. A mold support ring 12 is connected to the bracket 11. The mold support ring 12 is provided with a plurality of radially evenly arranged adjusting rods 13. An arc-shaped support block 14 is fixed at one end of the adjusting rod 13 facing the center of the mold support ring 12. The number of arc-shaped support blocks 14 is 6 to 12, and the plurality of arc-shaped support blocks 14 can form a hollow cylinder inward. In this embodiment, the number of arc-shaped support blocks 14 is 8. The adjusting rods 13 can move radially along the mold support ring 12, thereby changing the diameter of the circle formed by the arc-shaped support blocks 14.

[0025] like Figure 2 As shown, the mold support ring 12 has a radially extending support through hole. The outer surface of the mold support ring 12 also has a fixing ring 121 coaxial with the support through hole. The adjusting rod 13 is slidably fitted with both the fixing ring 121 and the support through hole. The adjusting rod 13 has a positioning through hole 131, and the fixing ring 121 is fitted with a positioning pin 122 that mates with the positioning through hole 131. After the adjusting rod 13 is moved within the support through hole to determine its position, it is fixed by the positioning pin 122.

[0026] In this embodiment, by setting a height-adjustable bracket 11, the height of the entire adjustable horn mold 1 can be adjusted according to the cable diameter. Simultaneously, through the structure of the mold support ring 12, the diameter of the inner circle formed by the arc-shaped support block 14 can be adjusted by moving the adjusting rod 13 radially to accommodate different specifications of metal sheaths required for cables of different diameters. Therefore, the height of the adjustable horn mold 1 and the shape and size of the shaping part of the present invention are all adjustable. For cables of different diameters, it can be directly adjusted to adapt. Even when producing different products, it is not necessary to replace each horn mold according to the cable diameter, saving time and labor, improving production efficiency, reducing the demand and inventory of horn molds, and lowering production costs.

[0027] like Figure 1 As shown, the bracket 11 includes symmetrically arranged support rods 111 hinged to the mold support ring 12. Each support rod 111 has a sliding rod 112 hinged to its bottom end, and the two sliding rods 112 are installed within the grooved base 113. The sliding rods 112 can move within the grooved base 113 or be fixed within it. Specifically, the sliding rods 112 can be positioned by a large frictional force between them and the grooved base 113; alternatively, a slot can be provided within the grooved base 113, and a positioning block that can engage with the slot can be provided on the sliding rod 112 for fixation; alternatively, a hole can be opened, and a pin can be used to fix the sliding rod 112. Other fixing methods are also possible.

[0028] like Figure 3 As shown, the present invention also provides a cable metal sheath production line, including the adjustable horn mold 1 as described above, an argon arc welding corrugated machine 2, and a gantry-type take-up machine 3. The cable 4, after being wrapped with a metal sheath by the adjustable horn mold 1, enters the argon arc welding corrugated machine 2 for welding. The gantry-type take-up machine 3 is used to wind up the welded cable 4. Specifically, as shown... Figure 4 As shown, the gantry-type take-up machine 3 includes a support shaft 32 mounted on a gantry frame 31. One end of the support shaft 32 is connected to an extension shaft 33. Bearings are provided between the extension shaft 33 and the support shaft 32, and between the support shaft 32 and the gantry frame 31, to ensure the rotation of the take-up machine. Furthermore, a position sensing arm 34 is hinged to the extension shaft 33. The position sensing arm 34 includes a vertically connected rotating rod 341 and a sensing rod 342. The rotating rod 341 is hinged to the extension shaft 33, and the sensing rod 342 is equipped with a position sensor that is signal-connected to the controller 35. The position sensing arm 34 is used to sense the position of the cable 4. The gantry-type take-up machine 3 is equipped with a controller 35 that is signal-connected to the position sensing arm 34, and the controller 35 is also electrically connected to a motor that drives the support shaft 32 to rotate.

[0029] In existing take-up frames, because the tension of the take-up frame remains constant, the weight of the spool increases after the cable is loaded, and the take-up speed is less than the output speed of the argon arc welding and corrugating machine, making the cable prone to dragging on the ground and causing abrasions. In this invention, as... Figure 5 As shown, a position sensing arm 34 is added at the support shaft 32. When the linear velocity of the cable 4 is greater than the production speed of the argon arc welding and corrugating machine 2, the height of the cable 4 above the ground increases. When the sensing arm 342 moves from point P to point P1 under the action of the cable 4, it triggers the controller 35 to send a signal to the motor at the take-up point, reducing the motor speed. The motor speed is adjusted according to the outer diameter value of the cable 4 and the pitch between cables 4 that have been input on the gantry take-up machine 3. When the linear velocity of the cable 4 is less than the production speed of the argon arc welding and corrugating machine 2, when the sensing arm 342 moves from point P to point P2 under the action of the cable 4, it triggers the controller 35 to send a signal to the motor at the take-up point, increasing the motor speed. The motor speed is adjusted according to the outer diameter value of the cable 4 and the pitch between cables 4 that have been input on the gantry take-up machine 3. This avoids the problem of tensile damage to the cable 4 or abrasion caused by the cable 4 rubbing against the ground.

[0030] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
