It should be understood that the specific embodiments described herein are merely illustrative of the present application and do not limit the scope of the actual protection. Well-known manufacturing methods, control procedures, component dimensions, material compositions, pipe arrangements, etc., have not been described in detail since they are readily understood by those of ordinary skill in the art, in order to avoid obscuring the present invention.

Fig. 1 is a front view of an embodiment of the present invention, referring to fig. 1, an embodiment of the present invention provides a rapid twisting device, including a feeding device 100, where the feeding device 100 is used to convey workpieces to be processed one by one. The specific structure of the feeding device 100 is not limited herein.

Referring to fig. 1 and 2, the twisting apparatus further includes a positioning mold apparatus 200, a knob mold core 300, and a rotating mold apparatus 400 in sequence, and is responsible for the main twisting process. The knob mold core 300 corresponds to a workpiece to be processed, and two ends of the workpiece to be processed correspond to the rotary mold device 200 and the positioning mold device 400 respectively.

Referring to fig. 2, 3 and 4, the positioning die device 200 is provided with a positioning die 210, and the positioning die 210 is provided with a positioning hole 211. The rotating die device 400 is provided with a rotatable knob rotating die 410, and a knob slot 411 is formed on the knob rotating die 410. Referring to fig. 5, the knob engaging groove 411 of the knob rotating mold 410 engages with one end of the portion to be twisted, the positioning mold 210 of the positioning mold device 200 engages with the other end of the portion to be twisted, and then the knob rotating mold 410 is rotated, so that the wire can be twisted on the knob mold core 300, thereby completing the twisting process.

Reference will now be made in detail to some embodiments, wherein "an embodiment" is referred to herein as a particular feature, structure, or characteristic that may be included in at least one implementation of the present application. The appearances of the phrase "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Furthermore, the details representative of one or more embodiments are not necessarily indicative of any particular order, nor are they intended to be limiting.

In embodiment 1, the feeding device 100 is located at the left side of the twisting device, and then the positioning die device 200, the knob mold core 300 and the rotating die device 400 are sequentially arranged from left to right, so that the whole structure is more compact.

The rack cylinder 412 is arranged at the rear side of the rotating die device 400, the rack cylinder 412 is connected with the spur rack 413, the rack cylinder 412 drives the spur rack 413 to move along the front and rear side directions, and then the knob rotating die 410 is driven to rotate, and the knob rotating die 410 has better torsion.

In embodiment 2, the feeding device 100 includes a blanking frame 110 and a blanking slot 120, and the blanking slot 120 is provided with a material pushing guide sleeve 130. The blanking frame 110 is used for collecting the arranged workpieces to be processed, and the blanking slot 120 is located at the output side of the blanking frame 110. The material pushing guide sleeve 130 pushes the workpiece to be processed into the positioning hole 211 of the positioning die 210.

For example, when the blanking frame 110 extends up and down, the blanking slot 120 is located at the lower end of the blanking frame 110 to receive the workpiece to be processed.

In embodiment 3, the rotary die apparatus 400 further includes a translation guide rail 420, an auxiliary return piston cylinder 430, and a follower spring 440. The rotary die apparatus 400 can translate along the translation rail 420. Referring to fig. 5, when the twisting process is performed, the follower spring 440 pulls the rotating die apparatus 400 toward the workpiece to be processed, so that the knob rotating die 410 is pressed toward the workpiece to be processed in cooperation with the twisting process. After the machining is finished, the auxiliary reset piston cylinder 430 pushes the rotary die device 400 away, so that the workpiece is separated from the knob die core 300 to be blanked.

The follower spring 440 may be a compression spring, an extension spring, an air spring, or other conventional spring structure, and the position of the follower spring 440 is not limited.

A positioning screw rod 450 is disposed beside the rotating die device 400 to limit the translational range of motion of the rotating die device 400. The positioning screw rod 450 is adjusted in position through the screw threads of the screw rod and is matched with the length of a workpiece to be finely adjusted. The positioning screw rod 450 of the embodiment divides the front side and the rear side of the rotating die device 400, avoids the dislocation caused by the extra torsion borne by the rotating die device 400 during the limiting, and divides the left side and the right side of the rotating die device 400 to limit the translation range.

Embodiment 4, a pressing device 500 is arranged above the knob mold core 300 and used for pressing a workpiece. For example, the hold-down device 500 includes a hold-down ram 510 and a hold-down cylinder 520. When the material pushing guide sleeve 130 sends the workpiece to the knob mold core 300 and aligns with the knob clamping groove 411, the pressing device 500 compresses the workpiece to match with the knob process, and the knob effect is ensured.

According to the above principle, the present invention can also make appropriate changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should fall within the protection scope of the claims of the present invention.
