It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0031] The following is in conjunction with the instruction manual appendix. Figure 1 and attached Figure 2 The pressing mechanism of this utility model will be introduced.

[0032] In one embodiment, such as Figure 1 and Figure 2 As shown, the pressing mechanism includes a material table 210, a push-pull assembly, and multiple pressing units 220.

[0033] The material platform 210 is provided with a plurality of guide grooves 212, and a plurality of pressing units 220 are used to clamp the material on the material platform 210. The pressing units 220 correspond one-to-one with the guide grooves 212, and the bottom of the pressing unit 220 is located in the guide groove 212 and can slide in the corresponding guide groove 212.

[0034] The push-pull assembly is disposed on the material platform 210 and fixedly connected to the plurality of pressing units 220, and is used to push the plurality of pressing units 220 to slide in the guide groove 212.

[0035] In use, multiple pressing units 220 clamp the material onto the material table 210. During the cutting process, the position of the multiple pressing units 220 can be adjusted by the push-pull assembly, thereby flexibly adjusting the position of the material. There is no need to re-clamp the tail material or adjust the clamping depth, which can improve the efficiency of cutting tail material and reduce tail material.

[0036] It should be noted that the material clamping mechanism of this utility model is not limited to use in wire cutting machines, but can also be applied to other equipment or scenarios that require clamping and fixing of materials.

[0037] In one embodiment, the push-pull assembly includes a drive member 241, a transmission assembly, and a connecting plate 242. The connecting plate 242 is fixedly connected to a plurality of pressing units 220. The transmission assembly is driven to the connecting plate 242. The drive member 241 drives the connecting plate 242 to move through the transmission assembly to guide the plurality of pressing units 220 to slide.

[0038] Specifically, the driving component 241 is a driving motor, the cross-section of the connecting plate 242 is L-shaped, the vertical section of the connecting plate 242 is fixedly connected to multiple pressing units 220, and the two ends of the horizontal section of the connecting plate 242 rest on the material table 210.

[0039] To reduce the resistance encountered by the connecting plate 242 during movement, guide rails can be provided between the two ends of the horizontal section of the connecting plate 242 and the material platform 210.

[0040] In addition, the pressing unit 220 is detachably connected to the connecting plate 242. During use, different numbers of pressing units 220 can be flexibly selected to clamp the material according to the size of the material.

[0041] In one embodiment, the transmission assembly includes two sets of lead screw and nut assemblies located on both sides of the connecting plate 242. Each lead screw and nut assembly includes a transmission lead screw and a transmission nut for transmission engagement. The two transmission nuts are fixedly connected to both ends of the horizontal section of the connecting plate 242. By rotating the transmission lead screw, the transmission nuts can drive the connecting plate 242 to slide along the guide groove 212, thereby causing the connecting plate 242 to drive multiple material pressing units 220 to slide along the guide groove 212, thus allowing for flexible adjustment of the material position.

[0042] Furthermore, to save costs, a single drive component 241 is used to drive the movement of two sets of lead screw and nut assemblies. Specifically, the transmission assembly also includes a transmission rod 243 and two sets of bevel gear assemblies. The transmission rod 243 is arranged in a direction perpendicular to the lead screw. The drive component 241 is a drive motor, which is fixedly connected to one end of the transmission rod 243. The two sets of bevel gear assemblies respectively transmit power to different positions of the two lead screws and the transmission rod 243, thereby causing the transmission rod 243 to drive the two lead screws to rotate through the two sets of bevel gear assemblies, causing the transmission nut to drive the connecting plate 242 to slide.

[0043] In other embodiments, two drive motors may be provided to drive two corresponding transmission screws to rotate.

[0044] In one embodiment, such as Figure 2 As shown, the pressing unit 220 includes a frame 230, an upper pressing plate 221, and a top pressing member 224. The upper pressing plate 221 is fixed to the output end of the top pressing member 224, and the top pressing member 224 is used to drive the upper pressing plate 221 to press the material onto the frame 230. Specifically, the top pressing member 224 can be an electric push rod, which can clamp or release the material by extending or retracting. In other embodiments, the top pressing member 224 can also be a hydraulic push rod or a pneumatic push rod.

[0045] In order to accommodate materials of different thicknesses, the frame 230 is also equipped with a track and a traction component. The traction component is used to drive the top pressing member 224 to slide along the track and fix the top pressing member 224 in a set position.

[0046] Specifically, the traction assembly includes a traction screw 222 and a traction nut 223 that rotatably engages with the traction screw 222. The traction screw 222 is rotatably disposed on the side of the frame 230 away from the upper pressure plate 221, and the traction nut 223 is fixedly connected to the top pressure member 224. Taking the top pressure member 224 as an electric push rod as an example, the lower end of the main body of the electric push rod is provided with a connecting plate 242. The frame 230 is provided with a through slot, and the connecting plate 242 passes through the through slot and connects to the traction nut 223. When the traction screw 222 rotates, the traction nut 223 can drive the electric push rod to move in the vertical direction through the connecting plate 242.

[0047] Preferably, in order to facilitate the rotation of the traction screw 222, a first rotating handle 245 is provided at the end of the traction screw 222.

[0048] In one embodiment, in order to accommodate different clamping depths of workpieces, the frame 230 includes a stand 231, a pressure plate 232, and an adjustment assembly. The pressure plate 232 is used to cooperate with the upper pressure plate 221 to clamp materials. The pressure plate 232 is guided and slidably disposed on the stand 231 along the extension direction of the guide groove 212. A limit block 233 is fixed on the pressure plate 232. The adjustment assembly is used to drive the pressure plate 232 to slide along the extension direction of the guide groove 212.

[0049] Specifically, the upright 231 is a long plate extending in the vertical direction, and the adjustment assembly includes an adjusting screw 234 and an adjusting nut that rotates with the adjusting screw 234. The adjusting screw 234 is rotatably disposed at the lower end of the upright 231, and the adjusting nut is fixedly connected to the pressure plate 232. By rotating the adjusting screw 234, the adjusting nut can drive the pressure plate 232 and the limiting block 233 on it to move.

[0050] In order to prevent the pressure plate 232 from rotating, the lower end of the frame 230 is provided with a guide rail extending along the axis of the adjusting screw 234, and the guide plate is provided with a slider that slides and guides the guide rail.

[0051] In addition, to facilitate the rotation of the adjusting screw 234, a second rotating handle 235 is provided at the end of the adjusting screw 234.
