Description

Technical Field

[0001] The present invention relates to the technical field of wire cutting machines, and in particular to an automatic wire collecting device and an automatic wire collecting method. Background Art

[0002] A wire-cutting machine primarily consists of a machine tool, a CNC system, and a high-frequency power supply. The CNC system, comprised of a single-chip microcomputer, keyboard, and frequency conversion detection system, provides key functions such as backlash compensation, linear and circular interpolation, and automatic wire breakage handling. It can cut materials with high strength, high toughness, high hardness, high brittleness, and magnetic properties, as well as precise, small, and complex-shaped parts.

[0003] For example, an automatic wire-threading wire cutting device with application number CN202310203342.2 and announcement date 20231027 includes a machine tool body; a wire storage mechanism for reeling and unreeling the wire electrode, the wire storage mechanism includes a wire storage barrel, and the outer wall of the wire storage barrel is provided with a clamping assembly for fixing the end of the wire electrode; a movable tube group wire-threading mechanism for threading the wire electrode, and the movable tube group wire-threading mechanism is provided with a translatable delivery tube at one end close to the wire storage barrel, and the hollow delivery tube can thread the wire electrode; when the wire storage barrel rotates to a preset position, the end of the delivery tube can be translated to act on the clamping assembly to make it open, and when the delivery tube is separated from the clamping assembly, the clamping assembly resumes the clamping state and clamps and fixes the end of the wire electrode; a clamping mechanism for clamping and delivering the wire electrode forward or backward. The transfer tube that can be moved horizontally, combined with the clamping assembly that can be opened and clamped, realizes the automatic clamping, wire clamping and wire removal of the wire electrode under the clamping action of the clamping mechanism, realizes automated operation and significantly improves processing efficiency.

[0004] For example, a method for automatic wire threading and unthreading of wire cutting with application number CN202310423717.6 and announcement date 20231013 is used for an automatic wire threading and unthreading device for wire cutting. The automatic wire threading and unthreading device for wire cutting includes a machine body, a wire threading mechanism, a wire feeding mechanism, a wire reel, a constant tension adjustment mechanism and a controller arranged on the machine body. The constant tension adjustment mechanism includes a tension sensor and a tensioning wheel. The tension sensor is used to detect the tension of the electrode wire. The tensioning wheel can adjust the tension of the electrode wire after moving up and down. A wire clamping mechanism is provided on the wire reel. The present invention can realize automatic wire threading and unthreading, has a high degree of automation, good wire threading and unthreading effect, and improves processing efficiency.

[0005] Most wire cutting machines use manual wire clamping for wire collection, which prevents the automatic wire collection function. This adds an extra step for the user. Some wire clamping methods use a receiving tube to forcefully enter between the spring and the wire collection barrel, and then open the spring to perform the wire clamping work. However, this method causes great wear on the equipment, such as the receiving tube, elastic clip, guide part, and wire storage barrel. Because the elastic clip is opened rigidly, the above structures are subject to great wear and tear, requiring frequent maintenance in the later stages. Otherwise, the normal use of the equipment may be affected or the automatic wire collection function may not be achieved. In addition, the transmission structure of the receiving tube is a separate structure. For machinery, the more structures there are, the more problems may arise. Summary of the Invention

[0006] The object of the present invention is to provide an automatic wire collecting device and an automatic wire collecting method to solve the above-mentioned deficiencies in the prior art.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] An automatic wire collecting device includes a cutting wire, a wire feeding tube, and a wire collecting drum. The wire collecting drum is provided with a cutting wire guide assembly, and the cutting wire guide assembly includes a guide tube. The guide tube is an arc-shaped hollow arrangement. The guide tube is provided with a cutting wire inlet and a cutting wire outlet. The direction of the cutting wire inlet is non-parallel to and adjacent to the direction of the cutting wire outlet; the cutting wire guide assembly is fixed to the surface of the wire collecting drum; the cutting wire guide assembly is a part of the wire collecting drum; the cutting wire inlet is provided with a guide nozzle; the edge of the guide nozzle away from the cutting wire inlet becomes smaller until it is the same as the cutting wire inlet; the guide nozzle is conical or trumpet-shaped.

[0009] An automatic wire collecting method comprises the following steps:

[0010] Step S1: Threading the wire: the wire feeding tube feeds the cutting wire head into the cutting wire inlet and into the cutting wire guide assembly, and the wire feeding tube continuously feeds the wire;

[0011] Step S2: The wire feeding tube continuously feeds the wire, and the wire head is sent out from the cutting wire outlet through the cutting wire guide assembly and intersects with the cutting wire body;

[0012] Step S3: After the wire head crosses the cutting wire body, the wire feeding tube continues to feed the wire while the wire receiving drum rotates and gradually accelerates, or the wire feeding tube gradually slows down the wire feeding, until the cutting wire body presses the wire head tightly, and the wire receiving drum and the wire feeding tube synchronize their wire feeding speeds;

[0013] Step S4: Wire collection, the wire collection drum continues to rotate until the work is completed.

[0014] In the above technical solution, the present invention provides an automatic wire collecting device and an automatic wire collecting method, which have the following beneficial effects:

[0015] (1) In the automatic wire-collecting technology designed by the present invention, after the wire feeding tube feeds the cutting wire from the cutting wire inlet, the cutting wire head is sent out from the cutting wire outlet and crosses with the cutting wire body. While the wire is continuously fed, the wire-collecting drum rotates to wind the cutting wire around the wire-collecting drum and press the cutting wire head, thereby achieving the purpose of automatic wire-collecting. The present invention does not increase the transmission mechanical structure, which greatly reduces the frequency of mechanical maintenance and the occurrence of failures.

The wire collecting drum 1 is provided with a cutting wire guide assembly 2, and the cutting wire guide assembly 2 includes a guide tube 3, and the guide tube 3 is an arc-shaped hollow setting. The guide tube 3 is provided with a cutting wire inlet 6 and a cutting wire outlet 7, and the direction of the cutting wire inlet 6 is non-parallel to the direction of the cutting wire outlet 7 and is adjacent to the direction; the cutting wire guide assembly 2 is fixed to the surface of the wire collecting drum 1; the cutting wire guide assembly 2 is a part of the wire collecting drum 1; the cutting wire inlet is provided with a guide nozzle 8; the edge of the guide nozzle 8 away from the cutting wire inlet 6 becomes smaller until it is the same as the cutting wire inlet 6; the guide nozzle 8 is conical or trumpet-shaped.

[0024] like Figure 1 As shown, an embodiment of the present invention provides an automatic wire collecting device, wherein a cutting wire guide assembly 2 is provided on the wire collecting drum 1, and the cutting wire guide assembly 2 is a part of the wire collecting drum 1. The design scheme is to set the guide tube 3 and the wire collecting drum as one piece. Since the wire collecting drum 1 is circular, the outer wall of the wire collecting drum 1 is set to an arc-shaped hollow state, and the positions of the corresponding cutting wire inlet 6 and the cutting wire outlet 7 are set to the same. This design scheme further reduces the structure, and there is no protruding structure on the surface of the wire collecting drum 1, making it more beautiful. What is important is that the winding of the wire during the wire collecting process is relatively even, and there will be no height difference.

[0028] Step S3: Pressing the wire. After the wire head crosses the main body of the cutting wire 5, the wire feeding tube 4 continues to feed the wire while the wire receiving drum 1 rotates, and the wire receiving drum 1 gradually accelerates, or the wire feeding tube 4 gradually decelerates the wire feeding, until the main body of the cutting wire 5 presses the wire head tightly, and the wire feeding speeds of the wire receiving drum 1 and the wire feeding tube 4 are synchronized;

[0029] Step S4: Wire collection, the wire collection drum 1 continues to rotate until the work is completed.
