[0039] The technical solutions of the present utility model will now be described with reference to the accompanying drawings. All other technical solutions obtained by those skilled in the art based on the technical solutions of the present utility model without inventive effort are within the scope of protection of the present utility model.

[0040] See Figures 1-4 This utility model provides a cutting device, including a frame, a cutting assembly, and a blocking assembly. The frame has a worktable 1 with a lower cutting edge. The cutting assembly is mounted on the frame and has a cutter 7 located above the lower cutting edge and a first driving device for driving the cutter 7 to move vertically. The blocking assembly is mounted on the frame and has a baffle 5 located on the feed side of the lower cutting edge away from the worktable 1 and a second driving device for driving the baffle 5 to move horizontally along the worktable 1. The horizontal movement of the baffle 5 changes the distance between the baffle 5 and the lower cutting edge.

[0041] The cutting device provided by this utility model can be used to cut materials (or workpieces) and can quickly adjust different cutting lengths as needed. The working principle is as follows: First, the second driving device drives the baffle 5 to move horizontally along the worktable 1 so that the distance from the baffle 5 to the lower cutting edge is consistent with the required cutting length. Then, the material is fed from the feeding side of the worktable 1 along the worktable 1 towards the baffle 5 until the end of the material touches the baffle 5. At this time, the material is placed on the worktable 1 and located below the cutter 7. Finally, the first driving device drives the cutter 7 to move downward until the cutter 7 moves to the lower cutting edge of the worktable 1 to cut the material.

[0042] It should be understood that after the cutter 7 cuts the material, it moves upward and returns to its original position under the drive of the first drive device, thus preparing for the next cutting process. It should be noted that the portion cut from the material, i.e., the part located between the baffle 5 and the cutter 7 when the cutter 7 cuts the material, can be the desired product or excess material to be discarded; this utility model does not limit this. If the cut portion is the desired product, and the remaining material is still greater than the cutting length, then the remaining material can continue to be fed towards the baffle 5 after the cutter 7 moves upward and returns to its original position (the previously cut portion of the material has been removed and will not obstruct the feeding of the remaining material), in order to complete the next cutting process.

[0043] It is easy to understand that when different cutting lengths are required, the baffle 5 can be driven to move horizontally along the worktable 1 using the second drive device before feeding. Therefore, the equipment provided by this utility model can adjust the cutting length according to actual needs, thereby well meeting the needs of different specifications.

[0044] In some embodiments, the material can be a silicon steel plate, and the desired product is a silicon steel sheet cut from the silicon steel plate. Of course, according to the technical principles of this invention, the above-described equipment can also be configured to cut other types of materials, such as a steel pipe cutting device. That is to say, when using the equipment of this invention, the material can be various different types such as plates and pipes, and this invention does not limit this.

[0045] See Figure 1 In some embodiments, the worktable 1 may be provided with a feeding channel 101 extending from the feed side towards the downward cutting edge. The cross-sectional shape of the feeding channel 101 matches the cross-sectional shape of the material. The feeding channel 101 helps to maintain a straight movement trajectory of the material during feeding, thereby reducing position adjustment work during feeding, enabling the material to be quickly placed in the accurate position, and improving work efficiency. Figure 1 In the exemplary embodiment shown, the feed channel 101 has a rectangular cross-section, suitable for sheet materials. Of course, in other embodiments, the cross-section of the feed channel 101 can be set to other forms according to the cross-sectional shape of the material. For example, when the material is a round tube, the cross-section of the feed channel 101 should be set to a circle.

[0046] See Figure 1 and Figure 2In some embodiments, the worktable 1 may be provided with a receiving groove extending horizontally and integrally connected to the lower cutting edge, with at least a portion of the baffle 5 located in the receiving groove. In this structure, the receiving groove and the lower cutting edge are integrally connected in the horizontal direction, and the baffle 5 moves horizontally along the receiving groove to move closer to and further away from the lower cutting edge. Furthermore, the baffle 5 may be configured to abut against the side wall of the receiving groove, thereby using the side wall of the receiving groove to limit the wobbling of the baffle 5 during horizontal movement, thus ensuring that the distance between the baffle 5 and the lower cutting edge after it is in place is more precisely consistent with the required cutting length.

[0047] In some embodiments, the receiving groove can be configured to vertically penetrate the worktable 1, and the sidewall of the receiving groove has a horizontally extending groove 102. The device includes at least two base plates 8 disposed in the receiving groove, and the base plates 8 are slidably engaged with the groove 102. In this structure, the receiving groove vertically penetrates the worktable 1, that is, the receiving groove does not have a solid bottom. Therefore, in order to support the material on both sides of the lower cutting edge, thereby cooperating with the cutting action of the cutter 7 to complete the cutting, two base plates 8 can be provided in the receiving groove. These two base plates 8 are located on both sides of the lower cutting edge to support the material. The base plates 8 can slide along the groove 102 on the sidewall of the receiving groove, which makes it easy to adjust the base plates 8 to a suitable position to support the material as needed. It is easy to understand that when the cutting length is set to a large value, more base plates 8 may be needed to support the material. Therefore, the number of base plates 8 can be more than two, and this utility model does not limit this. Figure 1 In the exemplary embodiment shown, the base plate 8 can be configured as a grid shape; in other embodiments, the base plate 8 can be configured as other structural forms, such as a flat plate. Furthermore, it should be noted that when the receiving groove has a solid bottom, i.e., when the receiving groove does not penetrate the worktable 1 vertically, the bottom of the receiving groove can provide support for the material.

[0048] See Figure 1 and Figure 2 In some embodiments, at least one side of the receiving groove 102 can be configured as a through groove extending from the inner wall of the receiving groove to the side surface of the workbench 1. The through groove is used for inserting the base plate 8 into the receiving groove, and one end of the base plate 8 is provided with a limiting block 801 located outside the through groove. In this structure, the base plate 8 is inserted into the receiving groove from the side of the workbench 1, that is, the end of the base plate 8 away from the limiting block 801 is aligned with the through groove and inserted towards the sliding groove 102 on the other side. The function of the limiting block 801 is to abut against the side surface of the workbench 1 to prevent the base plate 8 from being over-inserted. On the other hand, the limiting block 801 facilitates the operator's manual operation of the base plate 8 to move along the sliding groove 102 and to pull it out of the through groove. It is easy to understand that the limiting block 801 can be configured as a cuboid, sphere, or other shapes. It should be noted that in Figure 1 and Figure 2In the exemplary embodiment shown, only the groove 102 on one side of the receiving groove is configured as a through groove, while the groove 102 on the other side does not extend to the outer surface of the worktable 1. In other embodiments, both grooves 102 on both sides of the receiving groove may be configured as through grooves.

[0049] It should be understood that, in addition to setting the slide 102 as a through groove, the receiving groove can also be provided with other structures for mounting the base plate 8. For example, the width of the groove opening at a certain local position of the receiving groove can be set to be larger than the width of the groove opening at other positions, thereby allowing the base plate 8 to be directly inserted into the receiving groove from top to bottom from the relatively wider groove position and assembled onto the slide 102.

[0050] Based on the receiving slot extending vertically through the worktable 1, in some embodiments, the blocking assembly of the device may include: a movable block 4, located below the worktable 1 and connected to a second driving device; and a third driving device, disposed on the movable block 4 and connected to a baffle 5, for driving the baffle 5 to rotate between a horizontally laid-down state and a vertically erected state. In this structure, the second driving device drives the movable block 4 to move horizontally, and the third driving device and the baffle 5 move horizontally together with the movable block 4. Under the drive of the third driving device, the baffle 5 can rotate relative to the worktable 1, so that the baffle 5 has at least a horizontally laid-down state and a vertically erected state. It is easy to understand that when the baffle 5 is in the vertically erected state, it is convenient to contact the material in the feeding process, thereby accurately positioning the material on the worktable 1 so that the part cut by the cutter 7 conforms to the cutting length. When the baffle 5 is in the horizontally laid-down state, it is convenient to remove the part cut by the cutter 7 from the worktable 1. It should be noted that the baffle 5 can be switched to any transitional state between the horizontally laid-down state and the vertically erect state under the drive of the third drive device. That is, the baffle 5 can be switched to any acute angle tilt state. Therefore, when using the equipment, the baffle 5 can be adjusted to a tilt state at an acute angle with the horizontal plane, thereby realizing the fine adjustment of the cutting length.

[0051] In some embodiments, the third driving device may include: a first telescopic cylinder 401, the fixed end of which is fixedly connected to the movable block 4; a connecting rod 409, one end of which is hinged to the movable end of the first telescopic cylinder 401; an L-shaped rotating frame 407, one end of which is hinged to the movable block 4, and the other end of which is hinged to the end of the connecting rod 409 away from the first telescopic cylinder 401; and a baffle 5 fixed to the rotating frame 407. See also Figure 2 and Figure 4The connecting rod 409 is connected to the pushing rod 402 of the first telescopic cylinder 401 via the first hinge shaft 404, and the rotating frame 407 is connected to the moving block 4 via the second hinge shaft 406. Simultaneously, the rotating frame 407 is connected to the connecting rod 409 via the third hinge shaft 408. When the pushing rod 402 of the first telescopic cylinder 401 extends or retracts, the pushing rod 402 drives the rotating frame 407 to rotate around the second hinge shaft 406 via the connecting rod 409. Since the baffle 5 is fixed to the rotating frame 407, the baffle 5 rotates together with the rotating frame 407, thereby realizing the flipping motion of the baffle 5 relative to the worktable 1.

[0052] In some embodiments, a roller mounting plate 403 may be provided at the end of the push rod 402, and the roller 405 is provided at the end of the push rod 402 through the roller mounting plate 403. Moreover, a support part (which may be called a roller track) for the roller 405 to travel on is provided on the moving block 4. In this way, during the movement of the push rod 402 of the first telescopic cylinder 401, the roller 405 always forms a support at the end of the push rod 402, thereby making the movement of the push rod 402 more stable.

[0053] exist Figure 2 In the exemplary embodiment shown, the rotating frame 407 is provided with a support plate 410 for mounting the baffle 5. The support plate 410 can provide support for the baffle 5 over a larger area, thereby reducing the possibility of the baffle 5 deforming due to material impact during the feeding process. The type of the first telescopic cylinder 401 can be varied; for example, the first telescopic cylinder 401 can be configured as a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. This invention does not limit this type.

[0054] See Figures 1-3 In some embodiments, the first driving device may include: a portal-shaped support frame 6 fixed to the workbench 1; a second telescopic cylinder 601, the fixed end of which is fixedly connected to the support frame 6, and the movable end of which is connected to the cutter 7. The type of the second telescopic cylinder 601 can be varied; for example, it can be a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder, and this invention does not limit this. It is easily understood that the movable end of the second telescopic cylinder 601 extends and retracts vertically, thereby driving the cutter 7 to move vertically. In some embodiments, the device may include a vertically arranged slide rod 604, which slides in conjunction with the support frame 6, and is connected to the movable end of the second telescopic cylinder 601 via a horizontally arranged movable plate 603. The slide rod 604 guides the movable end of the second telescopic cylinder 601 during its extension and retraction movement, reducing swaying and making the movable end of the second telescopic cylinder 601 move more stably vertically. Figure 3In the exemplary embodiment, the number of slide rods 604 is set to two, and the two slide rods 604 are symmetrically arranged on both sides of the second telescopic cylinder 601. Of course, in other embodiments, the number of slide rods 604 can also be set to other values, such as three or four slide rods 604, and evenly distributed around the second telescopic cylinder 601. Figure 3 As shown, a limiting flange 605 can be provided at the upper end of the slide bar 604. When the slide bar 604 descends to the point where the limiting flange 605 abuts against the support frame 6, the limiting flange 605 can restrict the slide bar 604 from continuing to descend, which helps to improve the safety of the equipment.

[0055] In some embodiments, the device may include an elastic buffer 608 connected between the movable end of the second telescopic cylinder 601 and the cutter 7. The elastic buffer 608 can be of various types, such as a spring or rubber. The elastic buffer 608 provides cushioning for a short period after the cutter 7 contacts the material being cut. During this short period, the movable end of the second telescopic cylinder 601 continues to descend, causing the force applied by the cutter 7 to the material to increase slowly. This prevents the cutter 7 from impacting the material with a large force, thereby reducing the risk of damage to the cutter 7 from sudden impact. Figure 3 In the exemplary embodiment, the movable plate 603 is fixedly connected to the push block 602 at the movable end of the second telescopic cylinder 601, and the cutter mounting plate 609 is fixed to the lower end of the connecting post 606 that slides with the slide rod 604. It should be noted that the upper end of the connecting post 606 is provided with a limiting structure to prevent the connecting post 606 from falling off the slide rod 604. For example, the upper end of the connecting post 606 can be provided with a structure similar to the limiting flange 605, which is used to engage with the stop structure at the lower end of the slide rod 604, thereby preventing the connecting post 606 from falling off the slide rod 604. The upper surface of the cutter mounting plate 609 is provided with a force-bearing column 607. After the cutter 7 contacts the material to be cut, as the movable end of the second telescopic cylinder 601 continues to descend, the elastic buffer 608 is compressed until the lower end of the slide rod 604 abuts against the force-bearing column 607, at which point the elastic buffer 608 stops compressing. Afterward, further descent of the movable end of the second telescopic cylinder 601 will drive the cutter 7 to cut into the material. See also... Figure 3 In some embodiments, the cutter mounting plate 609 may be equipped with a protective sleeve 610 for protecting the cutter 7. The main body of the cutter 7 is installed in the protective sleeve 610, and the lower end of the cutter 7 extends outside the protective sleeve 610, which can complete the cutting operation of materials.

[0056] In some embodiments, the second driving device may include: a motor 3; a lead screw 201 rotatably mounted on the frame and connected to the output shaft of the motor 3; and a nut block 203 slidably mounted on the frame and rotatably engaged with the lead screw 201 for driving the baffle 5 to move horizontally. Figure 1and Figure 2 In the exemplary embodiment, a housing 2 is mounted on the frame of the device. A nut block 203 and a lead screw 201 are arranged inside the housing 2. A motor mounting plate 301 is connected to the outside of the housing 2. A motor 3 is located on the motor mounting plate 301 and connected to the lead screw 201. It is easy to understand that the lead screw 201 is horizontally arranged, and the forward and reverse rotation of the motor 3 can drive the nut block 203 to reciprocate along the axis of the lead screw 201, thereby moving the baffle 5 horizontally. In other embodiments, the second driving device can be configured in other forms; for example, the second driving device can be configured as a telescopic cylinder, which drives the baffle 5 to move horizontally through its telescopic movement. Figure 2 As shown, in some embodiments, the second driving device may include a limiting rod 202 arranged parallel to the lead screw 201. The limiting rod 202 passes through the through hole of the nut block 203 and is fixedly connected to the frame. The nut block 203 and the limiting rod 202 are slidably engaged. On the one hand, the limiting rod 202 can make the nut block 203 move only along the axial direction of the lead screw 201 and not rotate along the circumferential direction of the lead screw 201. On the other hand, it can make the horizontal movement of the nut block 203 more stable and reduce the shaking during the linear movement.

[0057] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
