Description

Technical Field

[0001] The present invention belongs to the technical field of wire bending machines, and more specifically, relates to a five-axis wire bending machine. Background Art

[0002] Metal wire bending products are important components of car seat frames, backrest frames, etc. The metal strips have small diameters, complex shapes, and are easy to deform. For a long time, in order to improve the production efficiency of steel wire products and reduce labor costs, various companies have been actively studying how to improve the automation level of wire bending production.

[0003] The existing wire bending machine includes a straightening mechanism, a wire feeding mechanism, a bending mechanism and a shearing mechanism. The wire is adjusted into a straight shape by the straightening mechanism, sent to the bending mechanism by the wire feeding mechanism for forming, and then sheared by reversing the wire. Usually, the bending mechanism consists of an inner mold core and an outer mold core. The metal wire enters the middle of the inner mold core and the outer mold core, and then the inner mold core and the outer mold core rotate to produce relative motion, so that the metal wire can be bent.

[0004] However, traditional wire bending machines only have three-axis control or four-axis control. When a three-axis controlled wire bending machine is used, the purpose of three-dimensional angle bending of the metal wire cannot be achieved and the straightening effect of the metal strip is poor, which is not conducive to the processing and production of the metal wire; when four-axis control is used, in order to ensure the straightening effect of the metal wire, the three-dimensional processing effect of the metal wire must be sacrificed. In order to ensure the three-dimensional processing effect of the metal wire, the straightening effect of the metal wire must be sacrificed, which seriously affects the quality of the bent wire products. Summary of the invention

[0005] In view of this, in order to solve the defects of the existing three-axis or four-axis controlled wire bending machine, such as poor straightening effect or inability to realize three-dimensional processing, the present invention proposes a five-axis wire bending machine, which includes an annular straightening mechanism 1, an XZ straightening mechanism 2, a wire feeding box 3, a bending head assembly 4, a cutting assembly 5, a frame body 6 and a hollow connecting mechanism 8. A single metal wire 7 is transferred from a material tray to the annular straightening mechanism 1 for pre-straightening. After the pre-straightening, the single metal wire 7 enters the XZ straightening mechanism 2 for secondary straightening. After the secondary straightening, it is determined that the concentricity of the metal wire meets the requirements. Then the single metal wire is output from the Z-axis straightening mechanism 22 of the XZ straightening mechanism 2, and then enters the wire feeding box 3. The height of the upper surface of the lower row of fixed rollers 36 in the wire feeding box 3 is consistent with the height of the upper surface of the lower row of rollers of the Z-axis straightening mechanism 22. This ensures that the concentricity of the metal wire can be maintained after the metal wire is output from the Z-axis straightening mechanism 22 of the XZ straightening mechanism 2 to the wire feeding box 3. The metal wire coming out of the wire feeding box 3 enters the cutting assembly 5 and moves to a position beyond the blade edge 511 of the cutter 51 under the action of the first motor 31 of the wire feeding box 3. The motor shaft of the third motor 43 moves to a certain position, thereby driving the inner mold core 41 or the outer mold core 42 to move to a specified angle and then stop, and then the fifth motor 53 drives the bending head assembly 4 to move upward to a specified position as a whole, so that the metal wire can be clamped in the gap between the first inner mold core 411 and the second inner mold core 412 of the inner mold core 41, and then the fifth motor 53 drives the bending head assembly 4 to rotate, so that the inner mold core 41 moves relative to the outer mold core 42, so that the metal wire is bent. In order to achieve a three-dimensional bending effect, the above operation During the operation, the movement of the second motor 32 can be increased, and the motor shaft of the second motor 32 can be connected to the entire bending head assembly 4 through a power connection mechanism, so as to control the rotational movement of the entire bending head assembly 4, so that the metal wire can be rotated at any angle in three-dimensional space, making the entire bending process of the metal wire more flexible; finally, when the bending of the metal wire is completed, the fifth motor 53 controls the entire bending head assembly 4 to descend, and then the fourth motor 52 controls the blade of the cutter 51 to rotate downward, so as to achieve the cutting of the bent metal wire. It can be seen that the five-axis wire bending machine of the present invention has better bending quality and is more flexible to process, which is conducive to the processing needs of different application occasions.
