Description

Technical Field

[0001] This utility model belongs to the field of bending machine technology, specifically relating to a base fixing device for a bending machine. Background Technology

[0002] When bending a steel plate, the steel plate is placed between the upper and lower dies. The upper die moves down to bend the steel plate. The lower die usually has several bending grooves on its upper surface. Each bending groove has a different shape and size. The operator will select different bending grooves according to the bending requirements, that is, align the upper die with the required bending groove, and then fix the lower die.

[0003] Common bending machines (such as) Figure 6 As shown, the device includes a base, with support plates fixedly connected to both ends on each side of the base. Each support plate is threaded with a threaded rod, and a clamping plate is rotatably connected to the inner end of the threaded rod. The lower die is placed on the base, and the clamping plate clamps the lower die by rotating the threaded rod in sequence, thus fixing the lower die. This fixing method has some drawbacks. For example, when selecting different bending grooves, the clamping plate must be loosened, the lower die moved, and then the lower die fixed. With this fixing method, the lower die is prone to tilting, making it difficult to straighten the lower die, and thus it is difficult to ensure that the bending groove on the lower die is aligned with the upper die. Moreover, as the usage time increases, the threaded rod will rotate under vibration, which will reduce the clamping force or even cause loosening, resulting in displacement of the lower die. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a base fixing device for a bending machine, which prevents the lower die from tilting when fixing the lower die, and facilitates the alignment of the bending groove on the upper end face of the lower die with the upper die.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A base fixing device for a bending machine, comprising:

[0007] A fixed base, wherein first protrusions are fixedly connected to both sides of the fixed base, and a threaded rod is rotatably connected between the two first protrusions;

[0008] A movable seat is disposed on the upper end of a fixed seat and threadedly connected to a threaded rod. Several positioning pins are fixedly connected to the upper end of the movable seat. Several sliding grooves are opened on both sides of the positioning pins at the upper end of the movable seat. Second protrusions are fixedly connected to both sides of the movable seat. Several sliding rods are slidably connected through each second protrusion. Springs are sleeved on the sliding rods. A movable plate is fixedly connected to the inner end of the sliding rod. Several limiting pins are fixedly connected to the inner side of the movable plate. Several sliders slidably connected in the sliding grooves are fixedly connected to the lower end of the movable plate.

[0009] The lower mold is located at the upper end of the movable base. The upper end of the lower mold has several bending grooves, the two sides of the lower mold have several limiting holes for inserting limiting pins, and the bottom of the lower mold has several positioning holes for inserting positioning pins.

[0010] The principles and technical effects of the above technical solution are as follows:

[0011] First, pull the sliding rod to move the moving plate away from the positioning post. At this time, the spring is compressed, aligning the positioning hole at the bottom of the lower die with the positioning post, so that the positioning post is inserted into the positioning hole. This positioning method straightens the lower die and prevents it from tilting, making it easy to align the bending groove on the lower die with the upper die. Next, release the sliding rod, and the spring force causes the moving plate to move to the lower die until the limiting post is inserted into the limiting hole. At the same time, because the lower end of the moving plate is fixedly connected to the slider, and the slider is slidably connected in the groove and will not disengage from the groove, the lower die cannot move vertically under the dual action. The positioning post prevents the lower die from moving horizontally. In this way, the lower die is fixed. When it is necessary to change the bending groove, the drive source drives the threaded rod to rotate. The threaded rod drives the moving seat to move, and the moving seat drives the lower die to move together until the required bending groove is aligned with the upper die. This method facilitates the movement of the lower die to change the bending groove without causing the lower die to tilt, and makes it easy to align the bending groove with the upper die.

[0012] In a preferred embodiment, the present invention can be further configured such that: a plurality of guide rods are fixedly connected between the two first bosses, and the guide rods pass through the movable seat so that the guide rods are slidably connected to the movable seat.

[0013] In a preferred embodiment, the present invention can be further configured such that the spring is sleeved on a slide rod between the movable plate and the second boss.

[0014] In a preferred embodiment, the present invention can be further configured such that a pull rod is fixedly connected to the outer end of the slide rod.

[0015] In a preferred embodiment, the present invention can be further configured such that the upper end of the positioning post has a raised arc-shaped structure.

[0016] In a preferred embodiment, the present invention can be further configured such that the end of the limiting post away from the moving plate has a raised arc-shaped structure.

[0017] In a preferred embodiment, the present invention can be further configured as follows: the two ends of the lower mold are provided with a plurality of first correction scale lines along the vertical direction, the center of each bending groove corresponds to one of the first correction scale lines, and the two ends of the fixing seat are provided with second correction scale lines along the vertical direction, the second correction scale lines being aligned with the center of the upper mold.

[0018] In a preferred embodiment, the present invention can be further configured such that: a motor is fixedly connected to the outer side of one of the first bosses, and the output end of the motor is fixedly connected to one end of the threaded rod.

[0019] In a preferred embodiment, the present invention can be further configured such that a support leg is fixedly connected to the lower end of the fixed base.

[0020] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0021] A fixed connection refers to a connection in which parts or components are fixed in place, with no relative movement between them. These connections are divided into two types: detachable and non-detachable.

[0022] (1) Detachable connections use screws, splines, wedges, etc. to fix parts together. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedges) and properly tightened.

[0023] (2) Non-removable connections mainly refer to welding, riveting, and tenon joints. Since disassembly is required by forging, sawing, or oxy-acetylene cutting during repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to the process quality, technical inspection, and remedial measures (such as correction, polishing, etc.) when making connections.

[0024] A threaded connection is a detachable connection in which threaded parts (or the threaded portion of the connected parts) are joined together as one unit.

[0025] A sliding connection refers to two objects that are in contact but not fixed, and can slide relative to each other.

[0026] A rotating connection is a connection between parts that allows the parts to rotate relative to each other.

[0027] The beneficial effects of this utility model are:

[0028] First, pull the sliding rod to move the moving plate away from the positioning post. At this time, the spring is compressed, aligning the positioning hole at the bottom of the lower die with the positioning post, so that the positioning post is inserted into the positioning hole. This positioning method straightens the lower die and prevents it from tilting, making it easy to align the bending groove on the lower die with the upper die. Next, release the sliding rod, and the spring force causes the moving plate to move to the lower die until the limiting post is inserted into the limiting hole. At the same time, because the lower end of the moving plate is fixedly connected to the slider, and the slider is slidably connected in the groove and will not disengage from the groove, the lower die cannot move vertically under the dual action. The positioning post prevents the lower die from moving horizontally. In this way, the lower die is fixed. When it is necessary to change the bending groove, the drive source drives the threaded rod to rotate. The threaded rod drives the moving seat to move, and the moving seat drives the lower die to move together until the required bending groove is aligned with the upper die. This method facilitates the movement of the lower die to change the bending groove without causing the lower die to tilt, and makes it easy to align the bending groove with the upper die.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0037] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0038] Based on the concept of this application, combined with Figures 1 to 5 This describes an embodiment of a base fixing device for a bending machine. Specifically, the base fixing device for the bending machine is constructed as a split structure, which has a fixed base 1, a movable base 4, a lower die 13, etc., working together. First, the sliding rod 8 is pulled to move the movable plate 10 away from the positioning post 5. At this time, the spring 9 is compressed, aligning the positioning hole 16 at the bottom of the lower die 13 with the positioning post 5, so that the positioning post 5 is inserted into the positioning hole 16. Through this positioning method, the lower die 13 is aligned and will not tilt, making it easy to align the bending groove 14 on the lower die 13 with the upper die. Then, the sliding rod 8 is released, and under the elastic force of the spring 9, the movable plate 10 moves to the lower die 13 until the limiting post 11 is inserted into the limiting hole 15. At the same time, due to the movement... The lower end of version 10 is fixedly connected to slider 12, and slider 12 is slidably connected in the slide groove 6 and will not detach from the slide groove 6. Under the dual action, the lower die 13 cannot move vertically, and the positioning post 5 prevents the lower die 13 from moving horizontally. In this way, the lower die 13 is fixed. When it is necessary to replace the bending groove 14, the drive source drives the threaded rod 3 to rotate. The threaded rod 3 drives the moving seat 4 to move, and the moving seat 4 drives the lower die 13 to move together until the required bending groove 14 is aligned with the upper die. This method makes it easy to move the lower die 13 to replace the bending groove 14 and will not cause the lower die 13 to tilt, making it easy for the bending groove 14 to be aligned with the upper die.

[0039] like Figures 1 to 5 As shown, a base fixing device for a bending machine includes:

[0040] Fixed base 1, with first bosses 2 fixedly connected to both sides of fixed base 1, and threaded rods 3 rotatably connected between the two first bosses 2;

[0041] The movable seat 4 is located on the upper end of the fixed seat 1 and is threadedly connected to the threaded rod 3. Several positioning pins 5 are fixedly connected to the upper end of the movable seat 4. Several sliding grooves 6 are opened on both sides of the positioning pins 5 on the upper end of the movable seat 4. Second protrusions 7 are fixedly connected to both sides of the movable seat 4. Several sliding rods 8 are slidably connected through each second protrusion 7. Springs 9 are sleeved on the sliding rods 8. A movable plate 10 is fixedly connected to the inner end of the sliding rod 8. Several limiting pins 11 are fixedly connected to the inner side of the movable plate 10. Several sliders 12 that are slidably connected in the sliding grooves 6 are fixedly connected to the lower end of the movable plate 10.

[0042] The lower mold 13 is located on the upper end of the movable seat 4. Several bending grooves 14 are opened at the upper end of the lower mold 13. Several limiting holes 15 for the insertion of limiting pins 11 are opened on both sides of the lower mold 13. Several positioning holes 16 for the insertion of positioning pins 5 are opened at the bottom of the lower mold 13.

[0043] In use, first pull the slide bar 8 to move the moving plate 10 away from the positioning post 5. At this time, the spring 9 is compressed, aligning the positioning hole 16 at the bottom of the lower mold 13 with the positioning post 5, so that the positioning post 5 is inserted into the positioning hole 16. This positioning method ensures that the lower mold 13 is upright and will not tilt, making it easy to align the bending groove 14 on the lower mold 13 with the upper mold. Next, release the slide bar 8, and under the elastic force of the spring 9, the moving plate 10 moves to the lower mold 13 until the limiting post 11 is inserted into the limiting hole 15. At the same time, since the lower end of the moving plate 10 is fixedly connected to the slider 12, and the slider 12 is slidably connected... Within the slide 6, the lower die 13 will not detach from the slide 6. Under the dual action, the lower die 13 cannot move vertically. The positioning pin 5 prevents the lower die 13 from moving horizontally. In this way, the lower die 13 is fixed. When it is necessary to replace the bending groove 14, the drive source drives the threaded rod 3 to rotate. The threaded rod 3 drives the moving seat 4 to move. The moving seat 4 drives the lower die 13 to move together until the required bending groove 14 is aligned with the upper die. This method facilitates the movement of the lower die 13 to replace the bending groove 14 and does not cause the lower die 13 to tilt, making it easy for the bending groove 14 to be aligned with the upper die.

[0044] In one embodiment of this utility model, a plurality of guide rods 17 are fixedly connected between the two first protrusions 2, and the guide rods 17 pass through the movable seat 4 so that the guide rods 17 and the movable seat 4 are slidably connected. The arrangement of the guide rods 17 makes the movement of the movable seat 4 more stable.

[0045] In one embodiment of this invention, a spring 9 is fitted onto a slide rod 8 between the movable plate 10 and the second boss 7. This arrangement allows the elastic force of the spring 9 to push the movable plate 10 to move downwards towards the mold 13.

[0046] In one embodiment of this utility model, a pull rod 18 is fixedly connected to the outer end of the slide rod 8. The pull rod 18 facilitates the operator to pull the pull rod 18 to move the slide rod 8.

[0047] In one embodiment of this invention, the upper end of the positioning post 5 has a raised arc-shaped structure. This design facilitates the insertion of the positioning post 5 into the positioning hole 16.

[0048] In one embodiment of this utility model, the end of the limiting post 11 away from the moving plate 10 has a raised arc-shaped structure. This design facilitates the insertion of the limiting post 11 into the limiting hole 15.

[0049] In one embodiment of this utility model, the lower mold 13 has several first correction scale lines 19 vertically formed at both ends, and the center of each bending groove 14 corresponds to one of the first correction scale lines 19. The fixed base 1 has second correction scale lines 20 vertically formed at both ends, and the second correction scale lines 20 are aligned with the center of the upper mold 21. Since the second correction scale lines 20 are aligned with the upper mold 21, when the moving base 4 moves the lower mold 13, when the first correction scale lines 19 are aligned with the second correction scale lines 20, the bending groove 14 corresponding to the first correction scale line 19 is aligned with the upper mold 21.

[0050] In one embodiment of this utility model, a motor 22 is fixedly connected to the outer side of one of the first bosses 2, and the output end of the motor 22 is fixedly connected to one end of the threaded rod 3. The motor 22 acts as a drive source to drive the threaded rod 3 to rotate.

[0051] In one embodiment of this utility model, a support leg 23 is fixedly connected to the lower end of the fixed base 1. The support leg 23 is provided to support the entire device.
