Description

Technical Field

[0001] The utility model relates to the field of cutting machines, in particular to a cutting machine. Background Art

[0002] A cutting machine is a mechanical device used for cutting, slotting, and drilling materials. Today's cutting machines typically utilize automated control, enabling rapid and efficient mass production, improving productivity. Compared to manual processing, cutting machines can reduce labor input, lower labor costs, and improve production efficiency. However, tool replacement and tool wear assessment require machine downtime and inspection.

[0003] However, when existing sawing machines are in operation, the tools on the clamping shaft and lower clamping shaft only partially contact the wood. The areas in frequent contact are prone to overheating or cracking. Furthermore, when processing thicker or multi-layered wood, the different degrees of wear on different parts of the tool lead to uneven cutting surfaces. In particular, because only parts of the tool are used, it is often easy for some parts to wear while other parts remain intact, failing to fully utilize the entire tool and resulting in serious waste. Furthermore, replacing the tool or adjusting its position at this time reduces production efficiency. Therefore, there is a need for a sawing machine that can extend the tool life and improve processing accuracy. Utility Model Content

[0004] In view of the above problems, the present invention aims to provide a cutting machine that can extend the service life of the tool and improve the processing accuracy.

[0005] To achieve this technical purpose, the solution of the utility model is: a cutting machine, including a fixed base movably mounted on a horizontal machine platform, a pusher clamping mechanism for fixing and clamping a wood board is installed on the fixed base, a vertical frame is further provided on one side of the horizontal machine platform, a punching mechanism and a horizontal drag plate provided with a cutting tool are respectively installed on both sides of the vertical frame, and the punching mechanism can be lifted and lowered in the vertical direction relative to the wood board on the pusher clamping mechanism;

[0006] The cross drag plate is slidably mounted on the vertical frame through a first horizontal rail, and a first power shaft and a second power shaft that can vertically lift and lower are installed on the cross drag plate. The first power shaft and the second power shaft are respectively connected to the two ends of the cutting tool for driving. The first power shaft and the second power shaft can drive the cutting tool to rotate while extending and retracting up and down.

[0007] Preferably, the transverse drag plate is further provided with a lifting drive mechanism capable of controlling the vertical lifting of the first power shaft, and the transverse drag plate is further provided with a synchronization mechanism capable of controlling the vertical lifting of the second power shaft synchronously with the first power shaft.

[0008] Preferably, the cross slide is an integrated structure with a notch groove, and the cross slide is a C-shaped structure. One side of the cross slide is slidingly connected to the first horizontal rail, the first power shaft is fixedly installed on the upper part of the cross slide, and the second power shaft is fixedly installed on the lower part of the cross slide. The wood board on the pushing and clamping mechanism can extend from the notch groove to the cutting tool driven by the first power shaft and the second power shaft.

[0009] Preferably, the transverse drag plate is a split structure, comprising a first drag plate and a second drag plate, wherein the first power shaft is fixedly mounted on the first drag plate, and the second power shaft is fixedly mounted on the second drag plate, and the first drag plate and the second drag plate are respectively slidably connected to the corresponding first horizontal rail.

[0010] Preferably, the pushing and clamping mechanism is composed of an upper chuck, a lower chuck, a fixed frame and a clamping drive mechanism. The upper chuck is hinged on the fixed frame, and the lower chuck is fixed to the lower part of the fixed frame. The clamping drive mechanism can drive the upper chuck on the fixed frame to rotate and clamp the wood board with the lower chuck.

[0012] Preferably, a support slide is provided below the pusher clamping mechanism, the support slide is slidably mounted on a first slide rail, a second slide rail is provided on the support slide, and the pusher clamping mechanism can slide horizontally along the X-axis direction through the second slide rail.

[0013] The beneficial effect of the present invention is that when the cutting machine of the present application is cutting, the cutting tool of the present application not only rotates but also telescopically moves up and down, which can make full use of all parts of the cutting tool, avoid local wear of the cutting tool, and extend the service life of the cutting tool; at the same time, the telescopic movement of the cutting tool while maintaining rotation can help with chip removal; at the same time, the telescopic movement can also avoid excessive local load on the cutting tool for a long time, effectively reducing the occurrence of micro-chipping or breakage of the cutting edge. After the cutting tool has been used for a period of time, due to the different wear conditions of each cutting edge, there will be obvious differences in the cutting surfaces at different heights, especially when processing multi-layer wood or thick wood workpieces. When cutting with the present application, the wood at the same height will contact multiple cutting edges on the cutting tool, which can effectively improve the cutting accuracy.

[0020] The following is combined with Figure 1-5 The utility model of this application is further described in detail with specific embodiments. In order to clearly and completely describe the technical solution, the following embodiments are selected for illustration; based on the contents recorded in this application, other embodiments obtained without creative work are all within the scope of protection of this utility model.

[0021] In the following embodiments, it should be noted that the terms "up", "down", "left", "right", "inside", "outside", "top / bottom" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of clearly describing the present embodiment, and do not indicate or imply that the device or element referred to must have a specific orientation. Therefore, they cannot be understood as limitations on this application.

[0022] Example 1

[0023] like Figure 1-3 As shown, the specific embodiment of the utility model is a cutting machine, which includes a fixed base 3 movably mounted on a horizontal machine table 1, on which four pusher clamping mechanisms 2 for fixing and clamping wood boards are mounted, a vertical frame 4 is further provided on one side of the horizontal machine table 1, and a punching mechanism 5 and a horizontal drag plate 7 provided with a cutting tool 6 are respectively mounted on both sides of the vertical frame 4, and the punching mechanism 5 can be lifted and lowered vertically relative to the wood board on the pusher clamping mechanism 2;

[0024] The transverse drag plate 7 is slidably mounted on the vertical frame 4 through the first horizontal rail 8, and the transverse drag plate 7 is equipped with a first power shaft 9 and a second power shaft 10 capable of vertical lifting activities; Figure 2The first power shaft is installed at the top, and the second power shaft is installed at the bottom, and vice versa. The first power shaft 9 and the second power shaft 10 are respectively connected to the two ends of the cutting tool 6. The first power shaft 9 and the second power shaft 10 can drive the cutting tool 6 to rotate and move up and down at the same time.

[0025] To ensure stable telescopic movement of the cutting tool, the cross carriage 7 is also equipped with a lifting drive mechanism that controls the vertical elevation of the first power shaft 9. A synchronization mechanism is also installed on the cross carriage 7 to control the vertical elevation of the second power shaft 10 in synchronization with the first power shaft 9. The lifting drive mechanism is one of a screw elevator, a helical screw elevator, a screw elevator, an electric push rod, and a ball screw elevator. The synchronization mechanism is composed of two or more slide bars.

[0026] The cutting tool of the present application can rotate and cut while also performing an upward and downward telescopic movement, so that the cutting edges at different heights on the cutting tool can all contact the wood, effectively avoiding excessive wear of the local cutting edges due to frequent cutting, and significantly extending the service life of the cutting tool. It can also avoid overheating, micro-collapse, or fracture caused by long-term high-load processing of the local cutting edges. At the same time, since the wood is in contact with multiple cutting edges at the same height during each cutting process, even if some of the cutting edges on the cutting tool are severely worn or fractured, the presence of cutting edges at multiple positions can ensure the smoothness of the wood cutting surface and improve cutting accuracy.

[0027] In order to improve the stability of the cutting mechanism, the cross slide 7 is an integrated structure with a notch groove. The cross slide 7 is a C-shaped structure. One side of the cross slide 7 is slidingly connected to the first horizontal rail 8. The first power shaft 9 is fixedly installed on the upper part of the cross slide 7, and the second power shaft 10 is fixedly installed on the lower part of the cross slide 7. The wood board on the pushing and clamping mechanism 2 can extend from the notch groove to the cutting tool 6 driven by the first power shaft 9 and the second power shaft 10.

[0028] To facilitate and stably clamp the wood planks, the pusher clamping mechanism 2 is composed of an upper chuck 201, a lower chuck 202, a fixed frame 203, and a clamping drive mechanism 204. The upper chuck 201 is hinged to the fixed frame 203, and the lower chuck 202 is fixed to the bottom of the fixed frame 203. The clamping drive mechanism 204 is a hydraulic cylinder that can drive the upper chuck 201 on the fixed frame 203 to rotate and clamp the wood plank with the lower chuck 202. The fixed base 3 is provided with four grooves 12 with sliding rails 11 and a horizontal drive mechanism 13. The pusher clamping mechanism 2 is slidably mounted in the grooves 12. The horizontal drive mechanism 13 can drive the pusher clamping mechanism 2 to extend and retract along the sliding rails 11, thereby achieving an avoidance operation (traditional clamping structures would obstruct the clamping area and make it impossible to process).

[0029] Example 2

[0030] like Figure 3 The transverse carriage 7 is a split structure, comprising a first carriage 701 and a second carriage 702, which are coaxially connected by synchronous operation. The first power shaft 9 is fixedly mounted on the first carriage 701, and the second power shaft 10 is fixedly mounted on the second carriage 702. The first carriage 8 and the second carriage 702 are respectively slidably connected to the corresponding two first horizontal rails 8.

[0031] Example 3

[0032] like Figure 4 , adding a support carriage, the pusher and clamping mechanism can clamp the wood to achieve X and Y compound motion, fix the power spindle, and thus achieve curved trajectory processing in the XY plane (the punching mechanism can omit the fixed carriage). A support carriage 14 is provided below the pusher and clamping mechanism 2. The support carriage 14 is slidably mounted on the first slide rail 16. The support carriage 10 is provided with a second slide rail 15. The pusher and clamping mechanism 2 can slide horizontally along the X-axis direction via the second slide rail 15. Based on the third embodiment, the punching mechanism can also retain the fixed carriage so that it can cooperate with the second horizontal rail to achieve horizontal movement of the punching mechanism.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any minor modifications, equivalent replacements and improvements made to the above embodiments based on the technical essence of the present invention should be included in the scope of protection of the technical solution of the present invention.
