Abstract

The present invention discloses a cable continuous bending device and method. The straightened cable is placed in the arc groove of the lower mold. By moving the upper mold downward to close the mold with the lower mold, the cable can be clamped and bent along the arc groove. Then, the controller controls the power assembly to drive the upper mold and the lower mold to move from the clamping position to the target position until reaching the target position. Then, the power assembly drives the upper mold to move upward to make the upper mold and the lower mold in a mold-opening state. The power assembly drives the upper mold and the lower mold to retreat to the clamping position in the opposite direction of the cable outgoing line. The controller controls the power assembly again to move the upper mold downward to clamp the straightened cable, causing the cable to bend and deform, and repeating the above actions to complete the continuous bending of the cable. Compared with the prior art, the cable in this application is directly fed into the bending mold for continuous bending after being straightened by the straightening mechanism after being drawn out from the cable reel, and its bending efficiency is higher.

Description

Technical Field

[0001] The present invention relates to the field of cable processing, and specifically to a cable continuous bending device and method. Background Art

[0002] With the development of high-speed train technology, it is necessary to consider bending large-diameter cable wires into a stator winding of a certain shape and size. When bending the cable wires, problems such as plastic forming of metal conductors, elastic deformation of cable insulation sheaths, bending insulation damage, and continuous forming of cable wires need to be considered.

[0003] In the prior art, a section of cable wire is clamped by a clamping sleeve and moved towards a bending die to complete feeding. The bending die consists of a main die and an auxiliary die. The main die and the auxiliary die are provided with semi-circular grooves for clamping bar-shaped workpieces. The main die drives the auxiliary die to rotate together to complete the bending of the bar. After bending, the main die retreats, and the clamping sleeve clamps the cable wire and continues to feed it towards the bending die. This process is repeated until the entire section of the cable wire is bent.

[0004] However, in the prior art, a whole section of cable needs to be straightened before being placed in the bending equipment for bending, which seriously affects the bending efficiency of the cable. Moreover, when the main die and the auxiliary die fit together to clamp the cable, it is easy to squeeze the cable, causing excessive deformation of the cable and damage to the outer insulation layer of the cable.

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] In this application, the term "comprising", "including" or any other variant thereof is intended to cover a non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, the element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including the element.

[0047] An embodiment of the present invention provides a cable continuous bending device. Refer to Figures 1 to 4 , Figure 1 which is the structural schematic diagram of the cable continuous bending device. The cable continuous bending device includes: a controller, a bending die 1, a straightening mechanism 2 and a power assembly;

[0048] The bending die 1 is arranged at the outlet of the straightening mechanism 2, and the straightening mechanism 2 is used for straightening the cable;

[0049] The controller is used to control the power assembly to drive the bending die 1 to move between the clamping position and the target position;

[0050] The bending die 1 includes an upper die 11 and a lower die 12;

[0051] An arc groove for bending the cable 4 is provided between the upper die 11 and the lower die 12;

[0052] The controller is also used to control the power assembly to drive the upper die 11 to move up and down, so that the upper die 11 and the lower die 12 are switched between the closed die state and the open die state.

[0053] It should be noted that the bending die 1 is arranged at the outlet of the straightening mechanism 2, and the bending die 1 is set as the upper die 11 and the lower die 12, and an arc groove for bending the cable 4 is arranged between the upper die 11 and the lower die 12; and the controller controls the power assembly to drive the upper die 11 to move up and down, so that the upper die 11 and the lower die 12 are switched between the closed die state and the open die state. When it is necessary to bend the cable 4 output from the straightening mechanism 2, only the straightened cable 4 needs to be placed in the arc groove of the lower die 12. By moving the upper die 11 downward, the upper die 11 and the lower die 12 form a closed die state, which can clamp the cable 4 and bend the cable 4 along the arc groove. Then, the controller controls the power assembly to drive the upper die 11 and the lower die 12 to move from the clamping position to the target position until it reaches the target position, that is, the feeding of the cable 4 is completed. Then, the power assembly drives the upper die 11 to move upward, so that the upper die 11 and the lower die 12 are in the open die state. The controller controls the power assembly to drive the upper die 11 and the lower die 12 to retreat in the opposite direction of the cable 4 outlet until it returns to the clamping position. The controller controls the power assembly again to make the upper die 11 move downward to clamp the straightened cable 4, so that the cable 4 is bent and deformed, and the above actions are repeated to complete the continuous bending of the cable 4. Compared with the prior art, the cable 4 of the present application is continuously bent directly in the bending die 1 after being straightened by the straightening mechanism after being drawn out from the cable reel 3, and the bending efficiency is higher.

[0054] It should also be noted that the present application takes into account the springback of the cable after bending. Therefore, when the bending angle of the arc groove provided between the upper die 11 and the lower die 12 is 90°, the bent cable is basically between 85° and 88°, and there will be certain differences in the same specification cables of different manufacturers.

[0055] Specifically, the power assembly includes: a first power assembly and a second power assembly;

[0056] The first power assembly is used to drive the bending die 1 to move between the clamping position and the target position;

[0057] The second power assembly is used to drive the upper die 11 to move up and down.

[0058] It should be noted that the first power component drives the bending die 1 to move between the clamping position and the target position. The cable 4 is clamped and bent by the bending die 1 at the clamping position. Then, the bending die 1 is moved to convey the cable 4 forward. When the bending die 1 moves to the target position and after the cable 4 is conveyed, the bending die 1 is separated from the cable 4 through die splitting. Then, the second power component moves the bending die 1 to the clamping position to clamp and bend the cable 4, and the above process is repeated to complete the continuous bending of the cable 4.

[0059] Driving the upper die 11 to move up and down by the second power component can switch the upper die 11 and the lower die 12 between the closed die state and the open die state. When it is necessary to clamp the cable 4, the second power component drives the upper die 11 to move downward. When the upper die 11 moves to a certain position, the upper die 11 and the lower die 12 are combined together. At this time, the upper die 11 and the lower die 12 are in the closed die state, which can clamp the cable 4 and enable the cable 4 to bend along the arc groove. When it is necessary to separate the upper die 11 and the lower die 12, only the second power component needs to drive the upper die 11 to move upward.

[0060] It should also be noted that in this application, the upper die 11 is moved to switch the upper die 11 and the lower die 12 between the closed die state and the open die state. In this review, the upper die 11 and the lower die 12 can also be switched between the closed die state and the open die state by moving the lower die 12, or by moving the lower die 12 and the lower die 12 simultaneously.

[0061] Furthermore, the first power component is a hydraulic cylinder.

[0062] It should be noted that a hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When using it to achieve reciprocating motion, a speed reduction device can be omitted, and there is no transmission gap, and the motion is stable. Therefore, the first power component of this application is set as a hydraulic cylinder.

[0063] It should also be noted that the first power component can be a hydraulic cylinder, and can also be other power components that can drive the bending die 1 to move between the clamping position and the target position, such as a pneumatic cylinder. Therefore, the first power component of this application is not limited to a hydraulic cylinder.

[0064] Preferably, the second power component is the same as the first power component.

[0065] It should be noted that setting the second power component as a hydraulic cylinder can make the upper die 11 move smoothly during the up and down movement. It can not only meet the clamping of the cable 4 by the cooperation of the upper die 11 and the lower die 12, but also make the bending deformation of the cable 4 more linear, avoiding damage to the cable 4 due to bending deformation.

[0066] Specifically, the straightening mechanism 2 includes: multiple groups of horizontal columnar rollers and multiple groups of vertical columnar rollers;

[0067] The multiple groups of the horizontal columnar rollers and the multiple groups of the vertical columnar rollers are arranged in a cross pattern.

[0068] It should be noted that setting the straightening mechanism 2 as the cross arrangement of multiple groups of horizontal columnar rollers and multiple groups of vertical columnar rollers can straighten the bent cable 4 by the rotation of the multiple groups of horizontal columnar rollers and the multiple groups of vertical columnar rollers, so as to facilitate the accurate clamping and bending of the cable 4 by the bending die 1. Because the cable 4 is not straight, it may cause that when the bending die 1 clamps the cable 4, the twisted part cannot be placed in the arc groove of the bending die 1, and the downward movement of the upper die 11 may damage the insulating layer of the twisted part of the cable 4.

[0069] Further, when the upper die 11 and the lower die 12 are in the closed die state, there is a clamping gap between the upper die 11 and the lower die 12.

[0070] It should be noted that by setting a clamping gap between the upper die 11 and the lower die 12 when the upper die 11 and the lower die 12 are in the closed die state, it can be avoided that when the upper die 11 and the lower die 12 move along the cable 4 outgoing line direction, the insulating layer of the cable 4 will not be damaged due to excessive extrusion caused by the required clamping force.

[0071] Preferably, referring to Figure 3 , the clamping gap b is 0.42 mm to 0.7 mm.

[0072] It should be noted that the clamping gap b can be selected by those skilled in the art according to needs, and is not limited to 0.42 mm to 0.7 mm.

[0073] Further, the cable continuous bending device further includes: a limit sensor;

[0074] The limit sensor is used to detect whether the upper die 11 moves to a preset point.

[0075] It should be noted that by setting a sensor for detecting whether the upper die 11 moves to a preset point, when the upper die 11 moves downward, when the limit sensor detects that the upper die 11 moves to the preset point, the limit sensor will send a stop signal to the power component. At this time, the upper die 11 will not continue to move downward. At this time, the distance between the upper die 11 and the lower die 12 is the clamping gap. When the upper die 11 and the lower die 12 move along the cable 4 outlet direction, it can avoid the clamping force of the upper die 11 and the lower die 12 from over-extruding the insulating layer of the cable 4 and causing damage.

[0076] Specifically, referring to Figure 3 , the diameter d of the arc groove is greater than the diameter of the cable 4, and the distance a between the center of the arc groove and the edges of the upper die 11 and the lower die 12 is 4 mm to 5 mm.

[0077] It should be noted that by setting the diameter d of the arc groove to be greater than the diameter of the cable 4 and setting the distance a between the center of the arc groove and the edges of the upper die 11 and the lower die 12 to be 4 mm to 5 mm, the cable 4 can be placed in the arc groove, and then by clamping the cable 4, the cable 4 can be bent into the required shape.

[0078] Furthermore, referring to Figure 4 , the cable continuous bending device further includes: a cage 5;

[0079] The cage 5 is arranged at the outlet of the bending die and is used for clamping the bent cable.

[0080] It should be noted that by arranging a cage at the outlet of the bending die, after the upper and lower dies of the bending die are separated, the cable is clamped by the cage 5, which can avoid the rebound of the bent cable.

[0081] Corresponding to the above cable continuous bending device, the present application also discloses a cable continuous bending method, as Figure 5 shown, the cable continuous bending method at least includes the following steps:

[0082] S1. At the clamping position, control the upper die and the lower die to clamp the straightened cable and bend the cable;

[0083] S2. Control the upper die and the lower die to convey the cable along the cable output direction to the target position;

[0084] S3. At the target position, control the upper die and the lower die to release the cable;

[0085] S4. Control the upper die and the lower die to return to the clamping position and re-execute S1.

[0086] It should be noted that at the clamping position, the upper die and the lower die are controlled to clamp the straightened cable to bend the cable; then the upper die and the lower die are controlled to convey the cable along the cable output direction to the target position; and at the target position, the upper die and the lower die are controlled to release the cable, and finally the upper die and the lower die are controlled to return to the clamping position to clamp the straightened cable again, and the above actions are repeated to complete the continuous bending of the cable. Compared with the prior art, the straightened cable in this application directly enters the bending die for bending, and the bending efficiency is higher.

[0087] Further, during the execution of step S1, the specific execution process of step S1 includes the following steps:

[0088] At the clamping position, the upper die is controlled to move downward so that the upper die and the lower die cooperate to clamp the cable.

[0089] It should be noted that by controlling the upper die to move downward, when the upper die moves downward to a preset point, the upper die and the lower die can cooperate to clamp the cable and bend the cable into a target shape.

[0090] Specifically, referring to Figure 6 , at the clamping position, the specific execution process of the upper die moving downward and the upper die and the lower die cooperating to clamp the cable includes the following steps:

[0091] S401. At the clamping position, when the upper die moves downward, the limit sensor real-time detects whether the upper die moves to the preset point. If the limit sensor detects that the upper die moves to the preset point, step S402 is executed. If the limit sensor does not detect that the upper die moves to the preset point, step S401 is continued.

[0092] S402. The limit sensor sends a stop signal to the power component.

[0093] It should be noted that at the clamping position, when the upper die moves downward, the limit sensor real-time detects whether the upper die moves to the preset point; when the limit sensor detects that the upper die moves to the preset point, the limit sensor sends a stop signal to the power component, and the power component stops driving the upper die to move downward, so that there is a certain gap (i.e., the clamping distance) between the upper die and the lower die, thereby avoiding the upper die moving downward to contact the lower die, and effectively avoiding the problem of insulation layer damage caused by excessive extrusion force on the cable when the upper die and the lower die convey the cable.

[0094] Further, after step S3 is executed, the following steps are also included:

[0095] Control the clamping bracket to clamp the bent cable.

[0096] It should be noted that when the clamping bracket returns to the clamping position after the upper die and the lower die are separated, the clamping bracket can avoid the springback of the bent cable by clamping the bent cable.

[0097] For the convenience of understanding, in combination with Figures 1 to 6 , the following further introduces this solution.

[0098] A continuous cable bending device, which is composed of straightening rollers, sensors, bending dies, etc. The cable passes through one end of the straightening rollers on the turntable and passes through the bending die. The bending die consists of an upper die and a lower die. The lower die is stationary, and the upper die moves up and down to realize relaxing and clamping the cable. The position of the limit sensor controls the up and down movement distance of the upper half die. After the bending die presses the cable tightly, there is a certain gap left to ensure that the clamping force required for wire feeding and the cable insulation layer will not be damaged by excessive extrusion. After the upper die and the lower die clamp the cable, they transport the cable to the left together. After the wire feeding is completed, the upper die moves up to feed the wire, and the upper and lower dies move to the right together to the specified position. The upper die moves down and clamps the cable again, and the die feeds the wire to the left, repeatedly realizing continuous wire feeding. The forming radius and the center position of the radius of the bending die ensure that the formed bend meets the requirements.

[0099] The points to be protected in this application are:

[0100] 1. The integrated straightening mechanism improves the bending efficiency of the cable. The moving mode of the bending die can realize the continuous forming of the cable, which is suitable for the forming of long-distance cables.

[0101] 2. The clamping gap b between the upper die and the lower die is 0.42 - 0.7 mm, and the clamping force of the forming die on the cable is 480 - 2270 N, which can ensure the continuous wire feeding of the bending die.

[0102] 3. The forming radius R of the bending die is 5 mm smaller than the required forming radius of the cable, the diameter d of the forming groove of the die is 1.3 - 1.5 mm larger than the diameter of the cable, and the distance a from the center of the forming groove to the edge of the bending die is 4 - 5 mm.

[0103] The continuous cable bending device of this application improves the bending efficiency of large-diameter cables through the integrated straightening mechanism. Through the movement of the upper half die, the clamping gap between the upper and lower dies, and the overall left and right movement of the die, it ensures the clamping force for the cable movement and does not damage the cable insulation, realizing the long-distance continuous bending of large-diameter cables. Through the bending radius of the bending die, the diameter of the bending groove and the center position, it ensures the bending radius of the cable after bending, without the need to control the cable bending control, simplifying the cable forming solution.
