Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a supporting device and a wire cutting machine tool. Background Art

[0002] Wire cutting machines usually have a certain range of travel. When using a wire cutting machine to process a workpiece, if the length of the workpiece is too long, then at the extreme position of the travel range, the upper carriage in a load-bearing state is prone to tipping over when the center of gravity of the carriage and the workpiece is seriously biased to one side, which may damage the machine tool and may also cause serious production quality and safety accidents. When the length of the workpiece exceeds the maximum effective support length of the machine tool, tipping accidents are prone to occur. For example, for the DK7780 wire cutting machine, the travel in the X-axis direction and the Y-axis direction are 800mm and 1200mm respectively. When processing a 3D printed workpiece with a length of 1250mm, when the Y-axis is at the extreme position of the travel range, the upper carriage in a load-bearing state is prone to tipping over when the center of gravity of the carriage and the workpiece is seriously biased to one side, which may damage the machine tool and may also cause serious production quality and safety accidents. Therefore, it is necessary to match the wire cutting machine of the appropriate model according to the size of the workpiece. When it is necessary to process different workpieces of various sizes, multiple models of wire cutting machine tools are required, which increases the processing cost. Utility Model Content

[0034] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention 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 cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] Before introducing the support device and the wire cutting machine provided by the utility model, the wire cutting machine in the prior art is first introduced. Figure 1 and Figure 2As shown, a conventional wire cutting machine example is provided, and the wire cutting machine 100 includes a machine body 110, a lower carriage 120, and an upper carriage 130. The lower carriage 120 is fixedly arranged on the machine body 110, and the upper carriage 130 is arranged on the lower carriage 120 and can move relative to the lower carriage 120. During processing, the workpiece P is placed on the upper carriage 130, and the workpiece P and the upper carriage 130 move relative to the lower carriage 120 together.

[0039] Figure 2 Another view of the prior art wire cutting machine 100 is schematically shown. During the machining process, if the length of the workpiece P is too long and the workpiece P is at the limit position of the travel range, the center of gravity of the workpiece P and the upper carriage 130 is seriously biased to one side, so that the upper carriage 130 is prone to tipping over, which may damage the machine tool and may also cause serious production quality and safety accidents.

[0040] In order to solve the above problems, this embodiment provides a supporting device and a wire cutting machine.

[0041] like Figure 3 and Figure 4 As shown, in this embodiment, a supporting device is provided, including: a supporting body 210 and a sliding part.

[0042] The support body 210 includes a connection portion 212 and a support portion 214. One end of the support portion 214 is connected to the connection portion 212, and the other end extends in a direction away from the connection portion 212. The connection portion 212 is suitable for connecting to a wire cutting machine. For example, the connection portion 212 can be installed on the edge of the wire cutting machine by welding, riveting, threading, and threaded hole matching. The support portion 214 increases the maximum support size of the wire cutting machine.

[0043] The sliding part includes at least one supporting roller 230, which is rotatably connected to the supporting part 214 through a supporting pin 220, the supporting pin 220 is perpendicular to the end surface of the supporting part 214, and the top outer edge of the supporting roller 230 is higher than the top surface of the supporting part 214. With such an arrangement, when the workpiece moves above the supporting part 214, the supporting roller 230 can support the workpiece instead of the supporting part 214, thereby improving the stability of the workpiece movement.

[0044] For example, the processing strokes of the wire cutting machine in the X-axis direction and the Y-axis direction are 800mm and 1200mm respectively. When processing a 3D printed workpiece with a length of 1250mm, the support device is set at the corresponding edge of the wire cutting machine, thereby increasing the maximum support size of the wire cutting machine, so that the processing in the Y-axis direction is greater than or equal to 1200mm. During operation, when the workpiece is driven by the wire cutting machine to the extreme position and continues to move, the edge of the workpiece will move to the support roller 230, and then the support roller 230 will support the workpiece and ensure that the workpiece can move smoothly, thereby avoiding tipping and damaging the machine tool.

[0045] In addition to the above examples, the support device can also be installed on wire cutting machines with other processing strokes.

[0046] The support device provided by the utility model can be connected to various types of wire cutting machine tools through the connecting part 212, has strong applicability, and improves the ability of various types of wire cutting machine tools to process workpieces larger than their own supporting dimensions.

[0047] like Figure 3 and Figure 5 As shown, in this embodiment, the connection part 212 and the support part 214 are plate-like structures, the end surface of the connection part 212 is perpendicular to the end surface of the support part 214, and the cross-sectional shape of the support body 210 is L-shaped. Such a configuration is conducive to improving the connection strength between the connection part 212 and the wire cutting machine tool. The connection part 212 and the support part 214 can be integrally formed, and of course, they can also be connected to each other by threaded connection, welding, etc.

[0048] like Figure 3 and Figure 4 As shown, in this embodiment, a through hole is provided on the support portion 214, and the through hole can be provided on the support portion 214 at a position close to its top surface. The support pin 220 passes through the through hole and is perpendicular to the end face of the support portion 214. The support roller 230 is rotatably connected to the support pin 220, which simplifies the connection structure of the support roller 230, reduces the manufacturing difficulty and production time, and can save production costs.

[0049] like Figure 3 and Figure 4 As shown, in this embodiment, the support roller 230 is connected to the support pin 220 via a ball bearing. For example, the ball bearing can be a standard ball bearing. While providing stable support, it can also ensure that the support roller 230 can roll in contact with the workpiece, thereby reducing the resistance applied to the workpiece.

[0050] like Figure 5As shown, in this embodiment, the first end 222 of the support pin 220 passes through the ball bearing to form a flange, and the second end 224 passes through the through hole and is threadedly connected to the nut. The flange can increase the support ability of the support pin 220 to the support roller 230 and share the pressure on the support roller 230. The nut can be a locking nut 240, and the locking nut 240 can improve the stability of the installation of the support pin 220.

[0051] like Figure 3 and Figure 4 As shown, in the present embodiment, at least two support rollers 230 are rotatably connected to the support portion 214 through their respective corresponding support pins 220, and the top outer edges of at least two support rollers 230 are located at the same height. The number of support rollers 230 can be two, three, four or even more, and can be determined according to the needs of the actual processing stroke. For example, the number of support rollers 230 can be three, which need to be respectively installed on the support portion 214 through three support pins 220, and the installation heights of the support pins 220 are the same, and the opening heights of the three through holes are the same, thereby ensuring that the top outer edges of the three support rollers 230 are at the same height, ensuring that the multiple support rollers 230 can provide stable support during the movement of the workpiece.

[0052] like Figure 6 As shown, in this embodiment, a wire cutting machine tool is provided, including: a bed 310, a first carriage 320, a second carriage 330 and the supporting device described above. The first carriage 320 is fixedly arranged on the bed 310. The second carriage 330 is arranged on the first carriage 320 and can move relative to the first carriage 320. The second carriage 330 moves relative to the first carriage 320 to drive the workpiece P to move in the X-axis direction and the Y-axis direction. A guide structure can also be arranged between the first carriage 320 and the second carriage 330.

[0053] The supporting device is installed on the end edge of the first drag plate 320 through the connecting portion 212. The supporting portion 214 has the same extension direction as the first drag plate 320. The height of the top outer edge of the supporting roller 230 is the same as the height of the upper surface of the first drag plate 320. The upper surface of the first drag plate 320 can be provided with a sliding unit. The sliding unit can be a structure such as a roller or a slider that can reduce linear friction. In this embodiment, the second carriage 330 is used to support the workpiece P and drive the workpiece P to slide, so the support roller 230 only needs to support the sliding of the second carriage 330. Then, the top outer edge of the support roller 230 and the bottom surface of the second carriage 330 are at the same height or a similar height, so that the second carriage 330 can be stably moved onto the support roller 230. When the edge of the second carriage 330 moves to the edge of the first carriage 320, the second carriage 330 continues to move and can move onto the support roller 230, which is equivalent to extending the maximum support size of the first carriage 320, so that the second carriage 330 and the workpiece P will not tip over during the processing of the workpiece.

[0054] In this embodiment, the connection portion 212 can be installed on the edge of the first carriage 320 by welding, riveting, threading and threaded hole matching connection, etc. The setting of the support roller 230 can provide good support and reduce the resistance of the second carriage 330 when moving, so that the movement is smooth and stable, and the drive motor of the wire cutting machine tool is prevented from stopping due to excessive resistance, thereby preventing the drive motor from being damaged.

[0055] like Figure 6 As shown, in this embodiment, two groups of supporting devices are arranged at opposite ends of the edge of the first drag plate 320, and there is a certain distance between the two groups of supporting devices, so that the second support plate 330 can be jointly supported by the two groups of supporting devices, thereby improving the stability of the movement of the second support plate 330.

[0056] like Figure 6 As shown, in this embodiment, supporting devices are provided on the edges of the two opposite sides of the first carriage 320, and when the second support plate 330 moves to the edge position of any end of the first carriage 320, it can be supported by the corresponding supporting devices. Such a setting can further extend the maximum support stroke of the first carriage 320, which is conducive to processing larger workpieces.

[0057] like Figure 3 and Figure 6 As shown, in this embodiment, the two groups of support parts 214 are located between the two groups of support rollers 230. Such an arrangement can ensure that both ends of the bottom of the second carriage 330 are evenly supported, further improving the stability of the movement. Alternatively, the two groups of support rollers 230 are located between the two groups of support parts 214, which can achieve the same stability effect.

[0058] For ease of explanation, the following will combine Figure 7 and Figure 8 The wire cutting machine processing status reference diagram shown is explained.

[0059] like Figure 7 As shown, two supporting devices are respectively installed on two opposite ends of the first carriage 320. When the second carriage 330 moves out of the left limit position of the travel range of the first carriage 320, the second carriage 330 is supported by the supporting device on the left side, so that it will not tip over.

[0060] like Figure 8 As shown, two supporting devices are respectively installed on two opposite ends of the first carriage 320. When the second carriage 330 moves out of the right limit position of the travel range of the first carriage 320, the second carriage 330 is supported by the supporting device 200 on the right side, so that it will not tip over.

[0061] The support device provided in this embodiment for installing the wire cutting machine is exactly the same as the support device introduced above, and the specific structure and beneficial effects of the support device are not repeated here.

[0062] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
