[0033] like Figure 1-4 As shown, a shearing machine for steel processing includes a main support platform 16 and a sub-support platform 3 arranged at one end of the main support platform 16, a gap is left between the main support platform 16 and the sub-support platform 3, so that the cutter 503 can cut the steel 4 here, and a box 1 for storing steel 4 is provided at the end of the sub-support platform 3 away from the main support platform 16, and the side of the box 1 close to the main support platform 16 is in an open state, and chains 9 are provided on both sides of the main support platform 16, and multiple groups of clamping plates 8 for clamping steel 4 are equipped on the chain 9, and the number of clamping plates 8 in each group is set to two, and the chain 9 drives the clamping plates 8 to move to pull the steel 4, so that the steel 4 is continuously cut by the cutter 503.

[0034] In order to assemble the splint 8 on the chain 9, a slider 11 is provided on the side of the splint 8 close to the chain 9, and the slider 11 is L-shaped as a whole. The splint 8 at the bottom is fixedly connected to the slider 11, and the splint 8 at the top is elastically matched with the slider 11. A support block 12 is sleeved on the outer side of the slider 11, and the support block 12 and the slider 11 are elastically matched. A connecting rod 13 is rotatably installed on the side of the support block 12 away from the splint 8, and a plug-in plate 15 is fixedly provided on the end of the connecting rod 13 away from the splint 8, and a plug-in block 14 matching the plug-in plate 15 is fixedly installed on the chain 9, and a limiting component matching the plug-in block 14 is provided on the plug-in plate 15. During the cutting process of the cutter 503, one group of splints 8 is located between the main support platform 16 and the auxiliary support platform 3, and during the cutting of the cutter 503 During the process, the clamping plate 8 on one side of the slider 11 and located above can be driven to move downward, and the steel 4 can be clamped by the cooperation of the two clamping plates 8. Afterwards, the clamping plate 8 is driven to move by the chain 9 to pull the steel 4, thereby preparing for the next cutting. When one end of the cut steel 4 is separated from the auxiliary support platform 3, it can be deflected downward to a vertical state and finally stacked in the box body 1. When the two adjacent plug-in plates 15 are in contact with each other at the top of the box body 1, the limiting assembly on the plug-in plate 15 is disengaged from the plug-in block 14, so that the plug-in block 14 is disconnected from the plug-in plate 15 and continues to move with the chain 9. This structure is conducive to pulling the steel 4 to move, thereby continuously cutting the steel 4 through the cutter 503. In addition, the set clamping plate 8 can stack the steel 4 in a vertical state in the box body 1, which is conducive to the subsequent use of the steel 4.

[0035] like Figure 2-7 As shown, a T-slot is provided on the side of the plug-in board 15 close to the chain 9, and a clip 19 that slides with the T-slot is fixedly provided on the plug-in block 14. Of course, the cross section of the clip 19 is set to be T-shaped here. The above-mentioned clip assembly includes a protrusion 30 elastically provided at the bottom wall of the T-slot. The side of the clip 19 close to the plug-in board 15 is provided with a groove that matches the protrusion 30. When the protrusion 30 pops out and is inserted into the groove, the plug-in board 15 and the plug-in block 14 are locked with each other.

[0036] Furthermore, a first magnetic block 6 and a second magnetic block 22 are respectively provided on the left and right sides of the plug board 15. The first magnetic block 6 and the second magnetic block 22 have different magnetic poles on the sides away from the plug board 15. Specifically, the second magnetic block 22 is slidably matched with the plug board 15, and a traction rope 29 is fixedly provided between the second magnetic block 22 and the protrusion 30. The traction rope 29 passes through the plug board 15 and slidably matches therewith. The above-mentioned first magnetic block 6 is fixedly embedded in the side of the plug board 15. When the two plug boards 15 are close to and fit together at the top of the box body 1, the traction rope 29 can be pulled by the suction force between the first magnetic block 6 and the second magnetic block 22, so that one end of the protrusion 30 is moved out of the groove.

[0037] Reference Figure 2 As shown, a positioning rod 7 is fixedly provided on the side of the top surface of the box body 1 away from the cutter 503 for positioning the first plug-in board 15 that slides onto the box body 1. Similarly, the first magnetic block 6 is also fixedly embedded in the side of the positioning rod 7 close to the cutter 503.

[0038] Reference Figure 6 As shown, a limit block 23 is elastically installed on the slider 11, and a limit groove 801 matching the limit block 23 is opened on the inner side surface of the upper splint 8, and the side of the bottom surface of the splint 8 close to the limit groove 801 is set as an inclined surface 802. When the cutter 503 is cutting, it can squeeze the side of the slider 11 and the splint 8 in the upper position, so that this splint 8 moves downward. When the limit block 23 is aligned with the limit groove 801, the limit block 23 can be inserted into the limit groove 801, thereby locking the splint 8 and the slider 11, which is conducive to clamping the steel 4 between the two splints 8.

[0039] In actual use, the steel material 4 to be cut is placed on the main support platform 16, and the staff pulls one end of the steel material 4 onto the auxiliary support platform 3. At this time, the clamping plate 8 on the chain 9 is located at one end of the main support platform 16 close to the auxiliary support platform 3. When the cutter 503 cuts the steel material 4 downward, the clamping plate 8 can be driven to move downward synchronously. Figure 5-6 As shown, when the clamping plate 8 on one side of the slider 11 and located above moves downward, the steel material 4 can be clamped between the two clamping plates 8, and when the limiting groove 801 on the clamping plate 8 is aligned with the limiting block 23, the limiting block 23 can pop out and insert into the limiting groove 801, thereby locking the clamping plate 8 above, so that the two clamping plates 8 can stably clamp the steel material 4;

[0040] After the steel material 4 is cut once, the chain 9 is driven to rotate so that the chain 9 can synchronously drive the clamping plate 8 thereon to move. In actual application, the distance that the clamping plate 8 moves along with the chain 9 each time is equal to the length of the cut steel material 4. In the process of the chain 9 driving the clamping plate 8 to move, the steel material 4 can be pulled, which is conducive to the cutter 503 to continuously cut the steel material 4. When one end of the cut steel material 4 leaves the auxiliary support platform 3, the steel material 4 will deflect downward with the clamping plate 8 as the center under the action of its own gravity and finally deflect into a vertical state. At this time, as the chain 9 continues to move, the vertical steel material 4 can be driven to one side of the box body 1 and stacked.

[0041] When the plug board 15 moves to the positioning rod 7, the second magnetic block 22 on the plug board 15 will be close to the first magnet 10 on the positioning rod 7, and the suction force between the two can pull the traction rope 29, so that the traction rope 29 can move one end of the protrusion 30 out of the groove, so that the plug block 14 and the plug board 15 are disconnected. At this time, the chain 9 can drive the plug block 14 to continue to move, while the plug board 15 is retained on the top surface of the box body 1. At the same time, the steel 4 clamped by the clamping plate 8 is also retained and stacked in the box body 1, which is conducive to the later use of the steel 4. Similarly, when the chain 9 drives the next group of clamping plates 8, sliders 11 and plug boards 15 to move to the top of the box body 1, as the two plug boards 15 approach each other, the first magnetic block 6 on one side of the plug board 15 cooperates with the second magnetic block 22 on the other plug board 15 to pull the traction rope 29, so that one end of the protrusion 30 is moved out of the groove.

[0042] In summary, this device is equipped with a clamping plate 8 that matches the steel 4 on the chain 9. During the movement of the chain 9, the steel 4 can be pulled, which is beneficial for the cutter 503 to continuously cut the steel 4. When the clamping plate 8 pulls the steel 4 so that one end of it is separated from the auxiliary support platform 3, the steel 4 can be deflected downward to a vertical state, which is beneficial for stacking the steel 4 in the box body 1. Since the steel 4 is stacked in a vertical state, it is convenient to take the steel 4 later.

[0043] As a further extension of the above scheme, refer to Figure 5-8As shown, a counterweight block 25 is slidably mounted on the slider 11, and the counterweight block 25 can slide along the length direction of the slider 11, and a first pull rope 24 is fixedly arranged between the counterweight block 25 and the limit block 23, and the first pull rope 24 passes through the slider 11 and slidably cooperates with it. When the splint 8 is placed on the main support platform 16 or the auxiliary support platform 3, the splint 8 and the slider 11 are in a horizontal state, and the limit block 23 is in a pop-up state, which is conducive to cooperating with the limit groove 801 on the splint 8, and when the splint 8 is in contact with the auxiliary support platform When the steel material 4 is separated from the frame 1 and moved to the box body 1, the weight of the cut steel material 4 can drive the clamping plate 8 and the slider 11 to rotate to a vertical state. At this time, the counterweight block 25 can move downward relative to the slider 11. During this process, the counterweight block 25 can pull one end of the limit block 23 out of the limit groove 801 through the first pull rope 24, so that the clamping plate 8 originally on the upper side is bounced up and reset, which is conducive to releasing the clamping of the clamping plate 8 on the steel material 4, so that the staff can take the steel material 4 alone without taking out the clamping plate 8 and other components.

[0044] Furthermore, a mounting groove that slides with the counterweight 25 is opened on the slider 11 along its length direction, one end of the first pull rope 24 is fixedly connected to the limit block 23, and the other end of the first pull rope 24 is fixedly connected to one end of the counterweight 25 close to the limit block 23, and an exhaust hole 1102 connected to the mounting groove is opened on the side of the slider 11. Through this structure, when the counterweight 25 slides downward along the mounting groove, the gas in the mounting groove can be squeezed out through the exhaust hole 1102. In addition, due to the setting of the exhaust hole 1102, the counterweight 25 slides downward at a slower speed, which is beneficial for the splint 8 to drive the cut steel 4 to one side of the box body 1 for stacking.

[0045] Reference Figure 6 As shown, one side of the support block 12 is an opening for accommodating the slider 11, so that the slider 11 slides at the opening, and a first spring is fixedly arranged between the slider 11 and the inner end surface of the opening, and circular holes are provided on the bottom surface of the inner cavity of the opening and on the side of the support block 12 away from the chain 9, and a clamping block 28 is slidably arranged at the circular hole in the opening, and a spring is fixedly arranged between the clamping block 28 and the inner end surface of the circular hole, and a second magnet 27 is slidably arranged in the circular hole on the side of the support block 12, and a second pull rope 26 is fixedly arranged between the second magnet 27 and the clamping block 28, and the second pull rope 26 passes through the support block 12 and slidably cooperates with it, and a clamping groove 1101 cooperating with the clamping block 28 is provided on the bottom surface of the slider 11;

[0046] Reference Figure 1-2 As shown, both sides of the top surface of the main support platform 16 and the auxiliary support platform 3 are recessed inward to form a recessed portion 17, referring to Figure 5As shown, a pressure strip 20 is fixedly provided on one side of the support block 12, and the connection point between the connecting rod 13 and the support block 12 is located at the center of the support block 12. Through this structure, when the chain 9 drives the support block 12 to move to the end of the main support platform 16 away from the auxiliary support platform 3, the support block 12 and the clamping plate 8 are in a vertical state due to the gravity of the pressure strip 20. As the chain 9 moves, the clamping plate 8 will contact the side edge of the recessed portion 17, thereby causing the clamping plate 8 to deflect. For details, please refer to Fig.11 The state of the clamping plate 8 shown in the figure, at this time, when the chain 9 continues to move, it can drive the clamping plate 8 to move completely to the recessed portion 17, and the clamping plate 8 located at the bottom of the slide plate is in contact with the bottom surface of the recessed portion 17, which is conducive to clamping the steel 4 through the two clamping plates 8;

[0047] Refer again Figure 1 As shown, a first magnet 10 that cooperates with the second magnet 27 is fixedly embedded on the outer side surface of the main support platform 16, and the opposite sides of the first magnet 10 and the second magnet 27 have different magnetic poles. In the initial state, the slider 11 is retracted inside the support block 12, so that the clamping plate 8 is staggered with the steel 4 in the vertical direction. When the chain 9 drives the clamping plate 8 to move to the recessed portion 17 and the first magnet 10 is aligned with the second magnet 27, the second pull rope 26 can be pulled by the attraction between the two, so that one end of the clamping block 28 is moved out of the clamping groove 1101, so that the lock between the slider 11 and the support block 12 is released, so that the slider 11 can pop out and drive the clamping plate 8 to move to the steel 4, which is beneficial to clamp the steel 4 later.

[0048] like Figure 1-2 As shown in 12, a side plate 2 is provided on the outer side of the chain 9, and sprockets are provided at both ends of the chain 9. Vertical plates are provided at both ends of the side plate 2, and a rotating shaft is fixedly provided on the sprocket. The rotating shaft passes through the vertical plate and rotates with the vertical plate. A motor is installed on one of the vertical plates, and the output shaft of the motor is transmission-connected with the rotating shaft. This structure is conducive to driving the chain 9 to rotate.

[0049] A support bar may also be fixedly mounted on the side plate 2 . The support bar is located below the chain 9 and is used to support the chain 9 to keep the chain 9 stable during operation.

[0050] A U-shaped bracket is fixedly arranged between the two side plates 2, and a hydraulic rod is fixedly installed on the bracket. A tool holder 5 is arranged outside the cutter 503. Specifically, an open groove for accommodating the cutter 503 is opened on the bottom surface of the tool holder 5, and a vertical rod 502 is fixedly arranged on the top surface of the cutter 503. The vertical rod 502 passes through the tool holder 5 and slides with it. A baffle is fixedly arranged on the top of the vertical rod 502. A limit spring is arranged between the baffle and the tool holder 5, and the limit spring can be sleeved on the outside of the vertical rod 502. The telescopic end of the hydraulic rod is fixedly connected to the baffle. Figure 5As shown, the bottom surface of the tool holder 5 is provided with a slot 501 which cooperates with the splint 8. In actual use, the tool holder 5 and the cutter 503 can be driven to move downward by the hydraulic rod, and the slot 501 on the tool holder 5 can overlap with the splint 8 at the end of the main support platform 16 in the vertical direction, thereby avoiding interference between the tool holder 5 and the splint 8 and driving the splint 8 to move downward.

[0051] Reference Figure 4 As shown, a boss 18 is rotatably installed at one end of the recessed portion 17 of the secondary support platform 3 close to the main support platform 16. Specifically, the top surface of the boss 18 is flush with the top surface of the secondary support platform 3. A hinge or hinge is installed between the side of the boss 18 away from the main support platform 16 and the secondary support platform 3, so that the boss 18 can rotate relative to the secondary support platform 3, and a spring is fixedly arranged between the side of the boss 18 away from the main support platform 16 and the secondary support platform 3. Through this structure, the boss 18 is in a state parallel to the end surface of the secondary support platform 3 under normal conditions. In actual use, when the chain 9 drives the splint 8 to move to the recessed portion 17 of the main support platform 16, When the auxiliary support platform 3 is in the position, the top surface of the clamp plate 8 is flush with the top surface of the main support platform 16, and the side of the clamp plate 8 away from the slider 11 is in contact with the side of the recessed portion 17. During the specific cutting process, the side of the clamp plate 8 is parallel to the end surface of the main support platform 16, and the side of the boss 18 is also flush with the end surface of the auxiliary support platform 3, which is beneficial to keeping the incision of the steel 4 neat during cutting. In addition, the width of the recessed portion 17 of the auxiliary support platform 3 can be greater than the width of the recessed portion 17 of the main support platform 16. Through this structure, when the chain 9 drives the clamp plate 8 to move to the auxiliary support platform 3, the clamp plate 8 can drive the boss 18 to deflect and finally pass over the boss 18.

[0052] like Figure 6 As shown, a guide rod is fixedly arranged between the lower clamping plate 8 and the slider 11, the guide rod passes through the upper clamping plate 8 and slides with it, and a support spring is sleeved on the outer side of the guide rod, and the support spring is located between the upper and lower clamping plates 8. A circular hole is opened on the slider 11 to slide with the limit block 23, and a second spring is fixedly arranged between the inner end surface of the circular hole and the limit block 23;

[0053] A blind hole is provided at the bottom of the T-shaped groove to be slidably matched with the protrusion 30, and a third spring is fixedly provided between the inner end surface of the blind hole and the protrusion 30;

[0054] Refer again Figure 6As shown, in actual use, the card strip 19 can also be elastically matched with the plug-in block 14. Specifically, a rectangular groove can be provided on the plug-in block 14, and the end of the card strip 19 close to the plug-in block 14 is slidably set in the rectangular groove. In addition, a guide column 21 can be fixedly installed in the rectangular groove, and the guide column 21 passes through the card strip 19 and slidably cooperates with it. A return spring is installed between the card strip 19 and the end surface of the rectangular groove. Through this structure, when the plug-in block 14 drives the plug-in board 15 to move, there is sufficient time for the first magnetic block 6 and the second magnetic block 22 to cooperate. Figure 7 A square groove is provided on the plug board 15 for slidingly cooperating with the second magnetic block 22 .

[0055] Reference Fig. 9 As shown, inclined guide surfaces 1901 are provided at both ends of the card strip 19, referring to Figure 1-2 , Fig.10 As shown, storage boxes 32 are provided on both sides of the bottom of the main support platform 16, and notches are opened on both sides of the top of the storage box 32. Baffles 31 are elastically installed at the notches, and the inner side of the baffle 31 is inclined. Specifically, a column can be fixedly installed on the bottom surface of the baffle 31, and the column extends into the storage box 32 and slidably cooperates with it, and a fourth spring can be fixedly installed between the baffle 31 and the bottom surface of the notch. Multiple groups of splints 8 and plug-in boards 15 and other structures are stored in the storage box 32, and a cylinder can be installed at the bottom end of the storage box 32. When actually used, the cylinder is used to push the multiple groups of splints 8 and plug-in boards 15 upwards, as shown in the figure. Fig.10 As shown, when the plug-in block 14 on the chain 9 moves to the storage box 32, the clamping strip 19 can be inserted into the plug-in plate 15. By setting a guide surface 1901 on the end face of the clamping strip 19, interference between the protrusion 30 and the clamping strip 19 can be avoided. When the protrusion 30 is aligned with the groove, the plug-in plate 15 is clamped with the plug-in block 14. At this time, the chain 9 can drive the plug-in plate 15 at the top of the storage box 32 and the clamping plate 8 and other components to move synchronously during the movement, thereby preparing for clamping the steel 4.
