[0001] The utility model relates to the field of metal processing, in particular to a sawing machine used for metal processing. Background Art

[0002] In the metal processing industry, sawing machines are important cutting tools and are widely used in the cutting of metal sheets. However, in the actual processing process, due to the large size of metal sheets and the limited space in the processing workshop, traditional metal processing sawing machines often face the problem of insufficient processing platform area. In order to solve this problem, the staff usually lift the part that exceeds the processing platform with equipment to ensure the level of the sheet. But this method has obvious defects:

[0003] The lifting height is difficult to control: Due to the large differences in the volume and weight of the plates, it is difficult to accurately control their height when lifting, resulting in the gap between the plate and the sawing machine being too large or too small, affecting the cutting quality.

[0004] Complicated steps: Lifting the plates requires additional equipment and manpower, which not only increases the difficulty of operation but also reduces work efficiency.

[0005] Safety risks: Accidents such as shaking or slipping may easily occur during the lifting process, posing a threat to the safety of workers.

[0006] Therefore, there is an urgent need for a sawing machine that does not take up space and can expand the processing platform. Utility Model Content

[0023] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as: above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as: first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0024] like Figure 1 The sawing machine is a three-dimensional structural diagram of the sawing machine, which includes a frame 1, a processing platform 2 is arranged on the upper side of the frame 1, and a ring band saw 3 is arranged on the rear side. The ring band saw 3 moves left and right along the frame 1, and its saw blade passes through the middle of the processing platform 2. A plurality of folding support members 4 are arranged side by side on the front side of the frame 1, and the plurality of folding support members 4 are arranged at the same height. Figure 2 The folding support member 4 includes a vertical support arm 41, a horizontal support arm 42 and an oblique support 43. The vertical support arm 41 is fixedly arranged on the upper front side of the frame 1. The upper and lower ends of the vertical support arm 41 are respectively movably provided with a first pin shaft 411 and a second pin shaft 412. One end of the horizontal support arm 42 is fixedly arranged on the first pin shaft 411. The horizontal support arm 42 rotates around the first pin shaft 411. The two ends of the second pin shaft 412 are respectively connected with an oblique support 43. The two oblique supports 43 are symmetrically arranged about the second pin shaft 412. One end of the support 43 is connected to the second pin shaft 412, and the other end is connected to a third pin shaft 431. The horizontal support arm 42 is provided with a long hole 421 which passes through horizontally along its length direction. The third pin shaft 431 is movably arranged in the long hole 421. The long hole 421 restricts the third pin shaft 431 so that the maximum opening angle of the horizontal support arm 42 is 90 degrees. An extension platform 5 is provided on the top of the horizontal support arm 42. When the horizontal support arm 42 is in the unfolded state, that is, in the open state of 90 degrees, the extension platform 5 is flush with the processing platform 2.

[0025] Specific reference Figure 2In order to prevent the horizontal support arm 42 from folding after placing a metal plate in the open state, a component for limiting the movement of the third pin is further provided, which is arranged at the bottom of the horizontal support arm 42, including a first threaded hole 422 opened on the horizontal support arm 42 and vertically penetrating the long hole 421, and a first screw rod 44 threadedly engaged with the first threaded hole 422. The third pin shaft 431 is limited by the first screw rod 44 to stabilize the open state of the horizontal support arm 42.

[0026] like Figure 2 , 3 and Figure 5 As shown, a slot 45 is provided at the bottom of the horizontal support arm 42, and the position of the slot 45 corresponds to the position of the second pin 412. When the horizontal support arm 42 is in the folded state, the second pin 412 is embedded in the slot 45. At this time, the angle between the horizontal support arm 42 and the vertical support arm 41 approaches 0 degrees. By providing the slot 45, the expansion platform 5 occupies less space in the folded state, and it is more convenient to store it at the bottom of the processing platform 2.

[0027] In addition, by providing an elastic pad 451 in the clamping slot 45, on the one hand, the second pin shaft 412 can be clamped to restrict the expansion platform 5 after folding, and on the other hand, it can also play a buffering role when folding.

[0028] like Figure 4 As shown, a slide rail 6 is provided between the extension platform 5 and the horizontal support arm 42, and the slide rail 6 is fixedly connected to the horizontal support arm 42. A slide groove adapted to the slide rail 6 is provided at the bottom of the extension platform 5. By setting the slide rail 6, the actual use area of ​​the processing platform 2 can be further expanded. When the horizontal support arm 42 is opened, if the area of ​​the extension platform 5 is not enough for use, the extension platform 5 can be pulled toward the side away from the processing platform 2, thereby further increasing the effective use area. In addition, in order to limit the position of the extension platform 5 and prevent it from detaching from the slide rail 6, a limiting structure for limiting the position of the extension platform 5 is provided on the slide rail 6, and the limiting structure includes a second threaded hole arranged along the vertical direction of the slide rail 6, and a second screw 7 matched with the second threaded hole.

[0029] In a preferred embodiment, a plurality of expansion platforms 5 are arranged side by side, and each expansion platform 5 is separately arranged on the folding support 4. Figure 6 The figure shows a schematic diagram of using two expansion platforms 5. By setting multiple expansion platforms 5, more shapes of plates can be adapted. In actual processing, due to the diversity of workpieces, some shapes are not very regular. This design can be adjusted according to the shape of the plate. It can be more flexible in terms of clamping, support level, etc.

[0030] The above-mentioned embodiments only express the preferred implementation of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
