Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wire EDM machine accessories, and more specifically, to a wire threading guide seat for wire EDM processing. Background Technology
[0002] In machining processes, especially in wire electrical discharge machining (EDM), it is often necessary to first establish the wire threading path for the electrode wire, such as molybdenum wire, copper wire, or galvanized wire, before proceeding with the cutting process. Currently, the common practice is to lead the electrode wire out from the wire EDM head using a wire feed guide, and then insert the electrode wire into the machining hole to complete the wire threading. However, in actual wire threading, the electrode wire may oscillate at the workpiece machining hole, especially when encountering a narrow, long gap hole. The electrode wire introduced into the gap hole is more prone to oscillation along the length of the gap hole, resulting in an unstable wire threading path and significantly reducing the success rate of wire threading. Therefore, overcoming the defects of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content
[0003] This utility model provides a wire threading guide seat for wire EDM, which aims to improve the problem that during the current wire threading process, the electrode wire swings inside the workpiece hole when threading the electrode wire, resulting in an unstable wire threading path and greatly reducing the success rate of wire threading.
[0004] To achieve the above objectives, this utility model provides a wire threading guide seat for wire EDM machining, the specific technical solution of which is as follows:
[0005] A wire threading guide seat for wire EDM includes a mounting base that can be mounted on the wire threading head of a wire EDM machine. A clamping head is provided on the lower side of the mounting base, and a wire guide tube is inserted into the middle of the clamping head. A locking cap is installed on the clamping head, and rotating the locking cap can lock and fix the wire guide tube to the clamping head.
[0006] In one embodiment, the outer diameter of the guide tube is smaller than the machining hole on the workpiece, and the guide tube can penetrate deep into the machining hole of the workpiece.
[0007] In one embodiment, the upper inlet of the wire guide tube is aligned with the wire feeding guide tube of the wire cutting machine's wire threading head.
[0008] In one embodiment, the clamping head has a through hole in the middle, the diameter of which is slightly larger than the outer diameter of the guide wire tube, and the guide wire tube can be inserted into the middle of the clamping head through the through hole.
[0009] In one embodiment, the lower end of the clamping head is provided with a tapered surface, a partition groove is provided on the tapered surface, and a tapered cavity adapted to the tapered surface is provided inside the locking cap.
[0010] In one embodiment, at least two partition grooves are provided, and the at least two partition grooves divide the conical surface into multiple parts.
[0011] In one embodiment, the upper end of the clamping head is provided with an external thread, and the inside of the locking cap is provided with an internal thread that matches the external thread.
[0012] In one embodiment, the mounting base and clamping head are an integral structure.
[0013] In one embodiment, the mounting base is provided with a spray hole.
[0014] In one embodiment, multiple spray holes are provided, and the multiple spray holes are evenly distributed around the clamping head.
[0015] The beneficial effects of this embodiment are:
[0016] By setting a mounting base at the wire outlet of the machine head, and a clamping head on the lower side of the mounting base, a wire guide tube is inserted into the clamping head. A locking cap is installed on the clamping head. The locking cap squeezes the clamping head, thereby clamping the wire guide tube. The wire guide tube can penetrate into the workpiece machining hole. In this way, the wire threading path of the electrode wire is established. Due to the guidance and limitation of the wire guide tube, the electrode wire will not swing in the workpiece hole. Especially when the workpiece hole is a slit hole, it can effectively suppress the swing of the electrode wire, greatly improve the success rate of electrode wire threading, and effectively improve work efficiency.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0030] The technical solutions provided by the embodiments of this utility model are described below with reference to the accompanying drawings.
[0031] Please see Figure 1-7This utility model provides a wire threading guide seat for wire EDM, including a mounting base 100, which is detachably mounted on the wire threading head of a wire EDM machine. A clamping head 110 is provided on the lower side of the mounting base 100. Preferably, the mounting base 100 and the clamping head 110 are an integral structure. The integral structure has good strength and can be integrally formed by mold, which is convenient to produce, aesthetically pleasing and durable. A wire guide tube 200 is inserted into the middle of the clamping head 110. A through hole is opened in the middle of the clamping head 110, and the diameter of the through hole is slightly larger than the outer diameter of the wire guide tube 200. Therefore, the wire can be inserted into the middle of the clamping head 110 through the through hole. The guide tube 200 has a wire-passing channel in the middle, through which the electrode wire can pass. The outer diameter of the guide tube 200 is smaller than the hole on the workpiece, so that the guide tube 200 can penetrate into the hole of the workpiece. The mounting base 100 is provided with spray holes 120, which are connected to the interior of the mounting base 100. Multiple spray holes 120 are provided, which are evenly distributed around the clamping head 110. Liquids such as water, cutting fluid or oil that enter the mounting base 100 can be sprayed out through the spray holes 120 and then sprayed onto the locking cap 300 and the guide tube 200 to achieve the functions of flushing, cleaning and cooling.
[0032] The upper inlet of the wire guide tube 200 is aligned with the wire feeding guide tube of the wire cutting machine's wire threading head (e.g., Figure 3 As shown), the electrode wire can be accurately inserted into the wire guide tube 200 after it extends out of the wire feeding guide tube. A locking cap 300 is detachably installed on the clamping head 110. A through hole is also opened in the middle of the locking cap 300. The diameter of the through hole is slightly larger than the outer diameter of the wire guide tube 200. Therefore, the wire guide tube 200 can pass through the locking cap 300 through the through hole.
[0033] Specifically, the lower end of the clamping head 110 is provided with a conical surface 111, and a dividing groove 1111 is provided on the conical surface 111. At least two dividing grooves 1111 are provided, and the at least two dividing grooves 1111 divide the conical surface 111 into multiple parts. The conical surface 111 is divided into multiple parts, so the rigidity of the individual parts after division is weakened, giving them a certain degree of elasticity. In addition, the locking cap 300 has a corresponding conical surface inside. A conical cavity 310 is adapted to the conical surface 111. After the conical surface 111 is pressed against the conical cavity 310, the conical cavity 310 can move upward relative to the conical surface 111 to squeeze the conical surface 111 inward. Preferably, an external thread 112 is provided on the outer side of the upper end of the clamping head 110, and an internal thread 320 adapted to the external thread 112 is provided on the inner wall of the locking cap 300. Under the cooperation of the internal thread 320 and the external thread 112, the locking cap 300 can be screwed and fixed on the clamping head 110.
[0034] After the locking cap 300 is screwed onto the clamping head 110, the locking cap 300 continues to rotate. Under the action of the thread, the locking cap 300 rotates upward on the clamping head 110. First, the conical cavity 310 and the conical surface 111 of the locking cap 300 fit together. Then, as the conical cavity 310 on the locking cap 300 continues to move upward, the conical cavity 310 presses the conical surface 111 inward, and the diameter of the through hole in the middle of the conical surface 111 becomes smaller. Thus, the conical surface 111 clamps the guide wire tube 200 inserted in the middle, thereby achieving the clamping and fixing of the guide wire tube 200.
[0035] By setting a mounting base 100 at the wire outlet of the machine head, and a clamping head 110 at the lower end of the mounting base 100, a wire guide tube 200 is inserted into the clamping head 110. The lower end outlet of the wire guide tube 200 extends outward a certain distance from the machine head. Then, a locking cap 300 is set on the clamping head 110. The locking cap 300 squeezes the clamping head 110, thereby clamping the wire guide tube 200. The wire guide tube 200 can be inserted into the hole of the workpiece. In this way, the wire threading path of the electrode wire is established, and the electrode wire will pass through the hole of the workpiece. Due to the guidance and limiting of the wire guide tube 200, the electrode wire will not swing in the hole of the workpiece. Especially when the hole of the workpiece is a slit hole, it can effectively suppress the left and right swing of the electrode wire, greatly improve the success rate of wire threading, and effectively improve work efficiency.
