Description

Technical Field

[0001] The utility model relates to the technical field of fastener processing equipment, in particular to a wire die head for a screw cutting machine. Background Art

[0002] When processing fasteners with external threads such as bolts, a cutting machine is usually used for segmentation and cutting. Since the material of the fasteners is relatively hard, the feed port of the wire die head body and the workpiece hole inside the wire die head body are easily worn during the continuous cutting process. Once worn, the workpiece will shake when cutting, which may easily cause the cutting blade to wear or be chipped. At the same time, the cutting accuracy of the workpiece will also be reduced due to the shaking. For this reason, once the wire die head body is worn, it needs to be replaced in time.

[0003] However, the two external clamping plates of the existing cutting machine wire die head body are an integrated structure, and then an installation cavity is hollowed out in the middle of the clamping plate to install the wire die head body into the installation cavity, which makes it inconvenient to replace the wire die head body. At the same time, the integrated clamping plate does not have a clamping force on the wire die head body, so as the workpiece is continuously pushed forward, it is also easy to cause the wire die head body to slide outward. Utility Model Content

[0004] The utility model aims to provide a wire die head for a screw cutting machine to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wire die head for a screw cutting machine, comprising a wire die head body, a workpiece hole is provided in the middle of the wire die head body; an upper clamping plate is provided above the wire die head body, and a lower clamping plate is provided below the wire die head body; mounting cavities for accommodating the wire die head body are provided on the facing surfaces of the upper clamping plate and the lower clamping plate; the wire die head body is fixed between the upper clamping plate and the lower clamping plate by closing the upper clamping plate and the lower clamping plate; the wire die head body is removed from between the upper clamping plate and the lower clamping plate by separating the upper clamping plate and the lower clamping plate.

[0006] As a preferred technical solution of the utility model: a latch is further provided on one side of the upper clamping plate facing the lower clamping plate, and a socket adapted to be connected with the latch is provided on the lower clamping plate.

[0007] As a preferred technical solution of the utility model: an annular groove is provided on the installation cavity, and the annular groove is adaptively connected with a protrusion provided on the wire die head body.

[0008] As a preferred technical solution of the utility model: a connecting hole is provided at the feed end of the wire die head body, and the connecting hole is connected to the wear-resistant part provided.

[0009] As a preferred technical solution of the utility model: the wear-resistant part is threadedly matched with the connecting hole, and a driving part is further provided at one end of the wear-resistant part away from the connecting hole.

[0010] By adopting the above technical solution, the beneficial effect of the utility model is: the wire die body is fixed between the upper clamp and the lower clamp by closing the upper clamp and the lower clamp. Therefore, the device utilizes the movable connection of the two clamps to complete the fixation of the wire die body while also facilitating the disassembly of the wire die body; in particular, the two clamps will squeeze the wire die body after being stressed, thereby further improving the stability of the wire die body after being connected to the two clamps. Based on this, in addition to solving the problem that the existing wire die body is inconvenient to replace due to wear, it can also ensure the stable and reliable position of the wire die body during operation, thereby ensuring the cutting accuracy of the workpiece.

[0017] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0018] See also Figure 1-5 The utility model provides an embodiment: a wire die head for a screw cutting machine, comprising a wire die head body 1, a workpiece hole 12 is provided in the middle of the wire die head body 1; an upper clamping plate 2 is provided above the wire die head body 1, and a lower clamping plate 3 is provided below the wire die head body 1; the upper clamping plate 2 and the lower clamping plate 3 are provided on the facing surfaces thereof with a mounting cavity 7 for accommodating the wire die head body 1; the wire die head body 1 is fixed between the upper clamping plate 2 and the lower clamping plate 3 by closing the upper clamping plate 2 and the lower clamping plate 3; the wire die head body 1 is removed from between the upper clamping plate 2 and the lower clamping plate 3 by separating the upper clamping plate 2 and the lower clamping plate 3.

[0019] In summary, the device utilizes the movable connection of the two clamping plates, which not only fixes the wire die body 1 but also facilitates the disassembly of the wire die body 1; in particular, the two clamping plates will squeeze the wire die body 1 after being stressed to prevent the wire die body 1 from moving outward with the workpiece 13. Therefore, the stability of the wire die body 1 after being connected to the two clamping plates can be improved.

[0020] Based on this, the device not only solves the problem that the existing wire die head body is inconvenient to replace due to wear, but also can ensure the stable and reliable position of the wire die head body 1 during operation, thereby ensuring the cutting accuracy of the workpiece.

[0021] In order to prevent the two clamps from sliding relative to each other after closing, a latch 6 is provided on the side of the upper clamp 2 facing the lower clamp 3, and a socket 9 adapted to be connected with the latch 6 is provided on the lower clamp 3. Therefore, after the latch 6 is inserted into the socket 9, the two clamps can be prevented from sliding relative to each other after closing, thereby further ensuring the clamping force of the two clamps on the line die body 1.

[0022] In order to further improve the stability of the wire die head body 1 in the installation cavity 7, the installation cavity 7 is provided with an annular groove 8, and the annular groove 8 is adapted to be connected with the protrusion 10 provided on the wire die head body 1. Therefore, after the protrusion 10 is stuck in the annular groove 8, the wire die head body 1 can be further prevented from sliding in the installation cavity, so that the wire die head body 1 works stably and reliably to ensure the cutting accuracy of the workpiece 13.

[0023] On the basis of the above scheme, since the feed end of the wire die body 1 is provided with a connection hole 11, and the connection hole 11 is connected to the wear-resistant part 4, the wear-resistant part 4 is directly in contact with the workpiece 13, so that the outer wall surface of the workpiece 13 directly acts on the wear-resistant part 4 to prevent the workpiece 13 from wearing the feed port of the wire die body 1 when moving. Therefore, the easily worn parts are transferred to the wear-resistant part 4 to extend the service life of the wire die body 1.

[0024] Specifically, since the wear-resistant part 4 is threadedly matched with the connecting hole 11, and a driving part 5 is also provided at one end of the wear-resistant part 4 away from the connecting hole 11, the installation and replacement of the wear-resistant part 4 are simple and convenient, thereby reducing downtime to improve the working efficiency of the equipment; wherein, the cross-section of the driving part 5 is a polygon.

[0025] In summary, the wire die head body 1 is connected to the annular groove 8 through the protrusion 10 and connected to the slot 9 by the pin 6, so that the wire die head body 1 is easy to disassemble and convenient for replacement of the wire die head body 1. At the same time, the pin 6 cooperates with the socket 9 and the protrusion 10 cooperates with the annular groove 8, so that after the wire die head body 1 is connected to the two clamping plates, its structural stability is comparable to that of an integrated structure, so that the wire die head body 1 basically does not have displacement phenomenon, thereby unifying the cutting length of the workpiece 13. In addition, the provision of the wear-resistant part 4 can extend the service life of the wire die head body 1, so the production efficiency of the equipment can be improved.

[0026] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
