[0026] In addition, the terms "first", "second", etc. are only used to distinguish in description and have no special meaning.

[0027] The spring machine with double-end chamfering function in this embodiment can be used for Figure 1 The spring includes a main body 110 and a first end 120 and a second end 130 connected to the main body 110, wherein the first end 120 is bent and the second end 130 is straight.

[0028] like Figure 2 and Figure 3As shown, the spring machine with double-end chamfering function of this embodiment mainly includes a workbench 1, and a wire feeding mechanism 2, a first chamfering mechanism 3, a forming mechanism 4, a clamping and rotating mechanism 5, a shearing mechanism 6 and a second chamfering mechanism 7 arranged on the workbench 1. Among them, the wire feeding mechanism 2 is used to feed the steel wire; the first chamfering mechanism 3 is used to chamfer the steel wire fed by the wire feeding mechanism 2, and this chamfering is to chamfer the bent first end of the spring; the forming mechanism 4 is used to bend the chamfered end of the steel wire after the first chamfering mechanism 3 chamfers the steel wire to form the first end of the spring, and also forms the main body of the spring; the clamping and rotating mechanism 5 is used to clamp the main body of the spring after the first end and the main body of the spring are formed, and at the same time, the clamping and rotating mechanism 5 can also rotate the spring in the subsequent process; the shearing mechanism 6 is used to shear the spring off the steel wire after the clamping and rotating mechanism 5 clamps the spring. When the shearing mechanism 6 shears the spring off the steel wire, the clamping and rotating mechanism 5 rotates the spring so that the first end of the spring turns away from the second chamfering mechanism 7 and the second end faces the second chamfering mechanism 7, and then the second chamfering mechanism 7 chamfers the second end of the spring.

[0029] With the above structure, the spring machine with double-end chamfering function described in this embodiment can chamfer both ends of the spring by providing a clamping and rotating mechanism 5 and a second chamfering mechanism 7, thereby reducing the circulation of the spring in multiple processes and improving work efficiency.

[0030] like Figure 2 As shown, a plurality of slides 8 are provided on the workbench 1 of this embodiment, and the above-mentioned first chamfering mechanism 3, forming mechanism 4, clamping rotation mechanism 5, shearing structure and second chamfering mechanism 7 are respectively arranged on the corresponding slides 8 and can slide along the corresponding slides 8.

[0031] like Figure 4 As shown, the first chamfering mechanism 3 of this embodiment mainly includes a first motor 31 and a first chamfering assembly 32. The first motor 31 is connected to the corresponding slide 8, and the first chamfering assembly 32 is connected to the output shaft of the first motor 31. The output shaft of the first motor 31 drives the first chamfering assembly 32 to rotate to achieve chamfering of the steel wire.

[0032] Preferably, if Figure 5As shown, the clamping and rotating mechanism 5 and the second chamfering mechanism 7 can be arranged on the same slide 8. Specifically, the clamping and rotating mechanism 5 may include a first mounting seat 51, a rotating clamping cylinder 52 and a pair of clamping claws 53. Among them, the first mounting seat 51 is connected to the corresponding slide 8, the rotating clamping cylinder 52 is installed on the first mounting seat 51, and the clamping claw 53 is installed on the rotating clamping cylinder 52. The second chamfering mechanism 7 includes a second mounting seat 71, a pen-shaped cylinder 72, a second motor 73 and a second chamfering assembly 74. The second mounting seat 71 is fixed on the first mounting seat 51, the pen-shaped cylinder 72 is installed on the second mounting seat 71, the second motor 73 is connected to the output shaft of the pen-shaped cylinder 72, and the second chamfering assembly 74 is installed on the output shaft of the second motor 73. By adopting the above scheme, after the shearing mechanism 6 cuts the spring from the steel wire, driven by the corresponding slide 8, the entire clamping and rotating mechanism 5 and the second chamfering mechanism 7 can retreat from the wire feeding mechanism 2 and then rotate and chamfer the second end of the spring. At the same time, since there is no interference between the clamping and rotating mechanism 5 and the second chamfering mechanism 7, the first chamfering mechanism 3 and the forming mechanism 4 can process the next spring, which is conducive to improving the working rhythm and improving the production efficiency of the spring machine.

[0033] To sum up, the working process of the spring machine with double-head chamfering function of this embodiment is as follows: the wire feeding mechanism 2 feeds out the steel wire, the first motor 31 drives the first chamfering assembly 32 to chamfer the steel wire for the first time, the forming mechanism 4 bends the end of the first chamfer to form the first end of the spring, and then forms the main body of the spring, the rotating clamping cylinder 52 drives the clamping claw 53 to clamp the main body of the spring, the shearing mechanism 6 shears the spring off the steel wire, the clamping rotating mechanism 5 and the second chamfering mechanism 7 withdraw from the wire feeding mechanism 2, the rotating clamping cylinder 52 drives the spring to rotate to the second end toward the second chamfering mechanism 7, the second motor 73 drives the second chamfering assembly 74 to chamfer the second end, and at the same time, the wire feeding mechanism 2, the first chamfering mechanism 3, and the forming mechanism 4 can synchronously prepare the next spring.

The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope.
