Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, the hydraulic clamping device for a scrap cutting machine includes a cutting table 1; a fixed plate 11 is fixedly connected to the top of the cutting table 1; a hydraulic cylinder 12 is fixedly connected to the top of the cutting table 1; a movable plate 13 is fixedly connected to the end of the hydraulic cylinder 12; both the fixed plate 11 and the movable plate 13 are provided with fixing components; a stabilizing component is provided on the movable plate 13; a cutting groove 14 is provided on the side wall of the cutting table 1; a collecting component is provided on the side wall of the cutting table 1; a control panel 15 is installed on the top of the cutting table 1; a protective component is provided on the top of the cutting table 1; a pad 16 is installed on the top of the cutting table 1; and a support component is provided on the side wall of the cutting table 1. During operation, when cutting a workpiece... The workpiece is placed between the fixed plate 11 and the movable plate 13. Then, the hydraulic cylinder 12 is stretched by the control panel 15, which moves the movable plate 13 toward the fixed plate 11 and clamps the workpiece with the fixing component. Then, the workpiece is cut. After the cutting is completed, the hydraulic cylinder 12 is contracted by the control panel 15, which moves the movable plate 13 away from the fixed plate 11, thereby releasing the workpiece from the fixation. With the above structure, the fixed plate 11, hydraulic cylinder 12, movable plate 13 and control panel 15 are set up. The workpiece can be quickly clamped and released by the stretching and contraction of the hydraulic cylinder 12, so as to reduce the slow clamping and releasing process caused by the use of screw clamps.

[0026] like Figure 1 and Figure 5 As shown, the fixing component includes two sets of clamping teeth 2; the two sets of clamping teeth 2 are respectively fixed to the side walls of the fixed plate 11 and the movable plate 13; the two sets of clamping teeth 2 are staggered; the clamping teeth 2 have a V-shaped structure; during operation, when the workpiece is pressed and fixed, the clamping teeth 2 will contact the surface of the workpiece, and the clamping teeth 2 on the movable plate 13 and the fixed plate 11 have a staggered structure. At the same time, the V-shaped structure of the clamping teeth 2 can clamp the workpiece inside, which can not only fix workpieces with square or polygonal cross sections, but also workpieces with circular cross sections. Through the above structure, the two sets of interlaced clamping teeth 2 can adapt to clamping and fixing workpieces with different cross-sectional shapes, so as to improve the applicability when pressing the workpiece.

[0027] like Figure 2 and Figure 4As shown, the collection assembly includes a fixed frame 3; the fixed frame 3 is fixedly connected to the side wall of the cutting table 1; a collection box 31 is slidably installed inside the fixed frame 3; a pair of fixed sleeves 32 are fixedly connected to the side wall of the collection box 31; a fixed ring 33 is fixedly connected to the side wall of the fixed frame 3; pins 34 are installed inside the fixed ring 33 and the fixed sleeves 32; during operation, the cutting blade is located above the cutting groove 14. Some of the iron filings generated during the cutting of the workpiece fall from the cutting groove 14 and are collected in the collection box 31 below. The collection box 31 can be periodically removed to recycle the iron filings inside, and then the collection box 31 is put back into the fixed frame 3 to reset it. Then, the pins 34 are inserted into the fixed sleeves 32 and the fixed rings 33 to fix the collection box 31 in the fixed frame 3. With the above structure, the fixed frame 3 and the collection box 31 can facilitate the collection of some of the debris generated during cutting, so as to facilitate the subsequent recycling of iron filings and reduce the pollution and waste of raw materials caused by iron filings.

[0028] like Figure 1 As shown, the support assembly includes a fixed base 4; the fixed base 4 is fixedly connected to the side wall of the cutting table 1; a support plate 41 is fixedly connected to the top of the fixed base 4; during operation, when a long workpiece is pressed between the cleats 2, the tail of the workpiece will exceed the length of the cutting table 1. At this time, the support plate 41 contacts the bottom of the workpiece, which can support and support the workpiece. Through the above structure, by setting the fixed base 4 and the support plate 41, the stability of long workpieces during cutting can be improved by supporting the tail side of the workpiece.

[0029] like Figure 2 As shown, the stabilizing component includes a pair of limiting rods 5; the pair of limiting rods 5 are symmetrically fixed to the side wall of the movable plate 13; a pair of limiting plates 51 are fixed to the top of the cutting table 1; the limiting rods 5 are slidably connected to the limiting plates 51; during operation, when the hydraulic cylinder 12 drives the movable plate 13 to move, the movable plate 13 will drive the limiting rods 5 to slide within the limiting plates 51. At this time, the limiting rods 5 and the limiting plates 51 will be reinforced from both ends of the movable plate 13. Through the above structure, by setting the limiting rods 5 and the limiting plates 51, the lateral force on the movable plate 13 when cutting the workpiece can be reduced, thereby reducing the possibility of loosening or breakage at the connection between the movable plate 13 and the hydraulic cylinder 12.

[0030] like Figure 1As shown, the protective assembly includes a protective cover 6; the protective cover 6 is rotatably connected to the top of the cutting table 1; during operation, when using the control panel 15, the protective cover 6 can be rotated upwards to expose the control panel 15; after use, the protective cover 6 can be rotated towards the control panel 15 to cover the control panel 15. Through the above structure, the protective cover 6 can cover or expose the control panel 15 to reduce accidental touches when the control panel 15 is not in use, and also to reduce damage caused by external objects hitting the control panel 15.

[0031] like Figure 1 As shown, a guide plate 7 is fixed to the side wall of the cutting table 1; the guide plate 7 is an inclined structure; during operation, the cut workpiece will fall onto the guide plate 7 and then roll along the inclined direction of the guide plate 7. At this time, a collection container can be placed below the guide plate 7 to collect the cut workpiece. Through the above structure, the guide plate 7 can buffer and guide the cut workpiece to reduce the damage caused by the strong impact force caused by the direct fall of the workpiece.

[0032] Working principle: When cutting a workpiece, the workpiece is placed between the fixed plate 11 and the movable plate 13. Then, the hydraulic cylinder 12 is stretched by the control panel 15, which moves the movable plate 13 towards the fixed plate 11 and clamps the workpiece through the fixing assembly. Then, the workpiece is cut. After the cutting is completed, the hydraulic cylinder 12 is retracted by the control panel 15, which moves the movable plate 13 away from the fixed plate 11, thereby releasing the workpiece from the clamp. When clamping the workpiece, the clamping teeth 2 will contact the surface of the workpiece. The clamping teeth 2 on the movable plate 13 and the fixed plate 11 have an interlaced structure. At the same time, the V-shaped structure of the clamping teeth 2 can clamp the workpiece inside. It can not only fix workpieces with square or polygonal cross sections, but also workpieces with circular cross sections. The cutting blade is located above the cutting groove 14. Some of the iron filings generated when cutting the workpiece fall from the cutting groove 14 and are collected in the collection box 31 below. The collection box 31 can be removed periodically to empty the contents. The iron filings are collected and then the collection box 31 is put back into the fixed frame 3 to reset. Then, the pin 34 is inserted into the fixed sleeve 32 and the fixed ring 33 to fix the collection box 31 in the fixed frame 3. When a long workpiece is pressed between the cleats 2, the tail of the workpiece will exceed the length of the cutting table 1. At this time, the support plate 41 contacts the bottom of the workpiece and can support and hold the workpiece. When the hydraulic cylinder 12 drives the movable plate 13 to move, the movable plate 13 will drive the limit rod 5 to slide in the limit plate 51. At this time, the limit rod 5 and the limit plate 51 will be reinforced from both ends of the movable plate 13. When using the control panel 15, the protective cover 6 can be rotated upward to expose the control panel 15. After use, the protective cover 6 is rotated towards the control panel 15 to cover the control panel 15. The cut workpiece will fall onto the guide plate 7 and then roll along the inclined direction of the guide plate 7. At this time, the collection container can be placed under the guide plate 7 to collect the cut workpiece.
