Description

TECHNICAL FIELD

[0002] As a commonly used cutting equipment, the metal cutting machine is widely used in production. With the continuous development of modern mechanical processing industry, the requirements for cutting machines are also increasing. In the prior art, the workpiece to be cut cannot be quickly fixed during cutting, and the cylindrical workpiece cannot be stably fixed, which affects the cutting precision and cannot realize multi-angle cutting. There is no locking mechanism when the metal cutting machine stops working or needs to be moved, which poses a safety hazard. When the saw blade is replaced, the saw blade is not fixed, which also poses a safety hazard.

[0003] In the prior art, the positioning and clamping mechanism of the metal cutting machine generally uses a manually rotating screw rod to drive the clamping block to move, so as to realize accurate positioning and firm clamping of the metal profile. However, in the actual operation process, the screw rod rotates slowly, resulting in a long clamping block adjustment time, which affects the positioning and clamping efficiency of the material. In addition, when continuously cutting metal materials, it is usually necessary to cut the materials into a uniform length to meet the use requirements. However, before each cutting, the operator has to repeatedly use a tape measure to measure and mark the material, which is a tedious and time-consuming process and seriously affects the metal processing efficiency.

[0056] The lead screw 41 is composed of a first threaded segment 411 and a second threaded segment 412, the second threaded segment 412 is located at the rear side of the first threaded segment 411, the rear side of the second threaded segment 412 is welded with a connecting head 413, the front side of the movable clamping block 4 and outside the connecting head 413 is provided with a connecting seat 42, the connecting seat 42 and the connecting head 413 are rotationally connected, the top of the cutting saw table 1 and below the lead screw 41 is provided with a sliding groove 13, the bottom of the connecting head 413 and the sliding groove 13 are slidingly connected, which can limit the lead screw 41 during adjustment, and improve the stability of the lead screw 41 and the movable clamping block 4.

[0057] The outer side of the second threaded section 412 is threadedly connected to a movable sleeve 45. A push block 451 is provided on the outer side of the movable sleeve 45. The push block 451 is rotatably connected to the outer circumferential wall of the movable sleeve 45. A control plate 452 is rotatably connected to the right side of the push block 451. The other end of the control plate 452 is rotatably connected to the right end of the movable clamping block 4.

[0058] When the movable sleeve 45 is rotated, the inner wall of the movable sleeve 45 is threadedly connected to the second threaded section 412, causing the movable sleeve 45 to move along the second threaded section 412. At the same time, the outer wall of the movable sleeve 45 is rotatably connected to the push block 451, which can drive the push block 451 to move back and forth. During the movement, one end of the control plate 452 rotates on the control plate 452, and the other end rotates on the movable clamping block 4, which drives the movable clamping block 4 to rotate around the connector 413, thereby adjusting the movable clamping block 4 to different angles.

[0059] In addition, angle marks are provided on the top of both connector 413 and connector 42, which play a positioning and alignment role during the adjustment of movable clamp 4, thereby improving the adjustment accuracy of movable clamp 4.

The top of the angle plate 44 is provided with an arc-shaped angle. When cutting steel pipes or angle steel, installing the angle plate 44 on the movable clamping block 4 can improve the fixing effect of the material.

[0062] like Figures 7-9 As shown, a threaded sleeve 511 is provided at the center of the worm gear 51. The threaded sleeve 511 is located outside the first threaded section 411 and is threadedly connected to the first threaded section 411. The front and rear ends of the threaded sleeve 511 are rotatably connected to the inner wall of the control base 5. A bearing 512 is installed on the inner wall of the control base 5 and located outside the threaded sleeve 511. The bearing 512 can reduce the frictional resistance of the threaded sleeve 511 and facilitate transmission. The worm 52 is located above the worm gear 51 and is rotatably connected to the left and right side walls of the control base 5. When the worm 52 rotates, the threaded sleeve 511 can be rotated through the transmission between the worm 52 and the worm gear 51. The threaded transmission between the threaded sleeve 511 and the second threaded section 412 can cause the lead screw 41 to move the movable clamping block 4 back and forth. In addition, since the worm 52 and the worm gear 51 have a self-locking function, it can prevent the movable clamping block 4 from driving the lead screw 41 to move in the opposite direction, ensuring that the fixed clamping block 3 and the movable clamping block 4 have a good positioning and clamping effect on the material.

[0063] The transmission gear 53 is located on the left side of the control base 5 and is coaxially driven with the rotating shaft of the worm 52. The sector gear 54 is located below the transmission gear 53 and is in meshing transmission with the transmission gear 53. The pedal 55 is on the same rotating shaft as the sector gear 54. The rear side of the pedal 55 is provided with an integrally formed pull frame 551, which facilitates pulling the pedal 55 to rotate forward. When the pedal 55 rotates, the sector gear 54 is driven to rotate synchronously through the rotating shaft. The meshing transmission between the sector gear 54 and the transmission gear 53 enables the sector gear 54 to drive the transmission gear 53 and the worm 52 to rotate rapidly for multiple turns during the movement, thereby facilitating the control of the movable clamp block 4 through the pedal 55.

[0064] The top of the cutting saw table 1 and below the rotating shaft of the pedal 55 are provided with a support seat 56, which supports the rotating shaft of the pedal 55 and improves the stability of the pedal 55. The top of the cutting saw table 1 and below the sector gear 54 are provided with a gear groove 14, which facilitates the rotation of the sector gear 54. The left side of the control base 5 is provided with a gear cover 57, which protects the transmission gear 53 and the sector gear 54.

[0065] As shown in Figure 1 , Figure 10 and Figure 11 , the right side of the cutting saw table 1 is provided with an end limiting mechanism, which includes a limiting seat 7 and a scale frame 71. The scale frame 71 is welded and fixed on the left side of the limiting seat 7 and is in sliding connection with the guide rail frame 11. The upper surface of the scale frame 71 is provided with a scale line. The front and rear sides of the scale frame 71 are both provided with a sliding block 711, which is in sliding connection with the guide rail frame 11. The scale line facilitates the control of the movement distance of the limiting seat 7, so that the limiting seat 7 has a stable distance with the cutting groove 12. During continuous cutting, the end of the material is limited by the limiting seat 7, which facilitates the continuous cutting of materials with the same length.

[0066] The bottom of the cutting saw table 1 and near the right edge are welded and fixed with a fixed block 72. The center of the scale frame 71 is rotatably connected with an adjusting screw 73, which is in threaded connection with the fixed block 72. When the adjusting screw 73 is rotated, the adjusting screw 73 moves relative to the fixed block 72, which drives the scale frame 71 to move, thereby regulating the movement distance of the limiting seat 7, which facilitates the cutting of materials with different lengths.

[0067] The top of the limiting seat 7 is provided with a limiting plate 74 near the right edge, which limits the end of the material. When the end of the material is aligned with the limiting plate 74, the fixed length of the material can be quickly cut through the cooperation of the ruler frame 71 and the limiting seat 7. The limiting seat 7 is provided with a clamping groove 75 on the left side of the limiting plate 74. The inner side of the clamping groove 75 is clamped and fixed with a supporting plate 76. The top of the supporting plate 76 is provided with a plurality of evenly distributed arc-shaped blocks 761. When the bottom of the supporting plate 76 is clamped with the clamping groove 75, the arc-shaped blocks 761 are arranged upward. The arc-shaped blocks 761 can limit the pipe during cutting, improving the stability of the pipe during cutting. When the top of the supporting plate 76 is clamped with the clamping groove 75, the arc-shaped blocks 761 are accommodated in the inner part of the clamping groove 75, so that the top of the limiting seat 7 is flat, facilitating the cutting and processing of the plate.

[0068] Working principle: when the device is continuously cutting the material, first, rotate the adjusting screw 73 to make the adjusting screw 73 move relative to the fixed block 72, and make the sliding block 711 slide along the guide rail frame 11. The scale line on the upper surface of the ruler frame 71 is used for assistance. According to the length requirement of the material, the limiting seat 7 is adjusted to the corresponding position, so that the distance between the limiting plate 74 and the cutting groove 12 is equal to the length of the material;

[0069] Further, the material to be cut is moved to the top of the cutting saw table 1, and the rear edge of the material is aligned with the fixed clamping block 3, and the right edge of the material is aligned with the limiting plate 74. The end of the material is supported by the limiting seat 7. Then, step on the pedal 55 to make the pedal 55 drive the fan-shaped wheel 54 to rotate synchronously. Through the meshing transmission between the fan-shaped wheel 54 and the transmission gear 53, the worm 52 is driven to rotate. Through the transmission between the worm 52 and the worm gear 51, the worm gear 51 drives the threaded sleeve 511 to rotate. The threaded transmission between the threaded sleeve 511 and the second threaded section 412 drives the lead screw 41 to move forward and backward along the sliding groove 13, and drives the movable clamping block 4 to move quickly, so as to quickly position and clamp the material, improving the cutting efficiency of the material.
