Description

Technical Field

[0001] This utility model belongs to the field of bending machine technology, specifically relating to a bending machine material blocking mechanism. Background Technology

[0002] A CNC bending machine is essentially a CNC bending die for bending steel plates. The die consists of a support, a worktable, and a clamping plate. By energizing the coil, an attractive force is generated on the pressure plate, thereby clamping the thin plate between the pressure plate and the base. The plate is placed in horizontally, and a stop device is provided to limit the horizontal movement position to ensure the accuracy of the bending position.

[0003] The existing material blocking device blocks and limits the material. When the material is bent, the side of the material that contacts the material blocking device rubs against the device. Over time, this causes damage and leads to errors when limiting the material in subsequent applications. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a material blocking mechanism for a bending machine, which can prevent the side of the steel plate from warping up and rubbing against the baffle when the steel plate is bent, avoid baffle wear, and reduce the error caused by limiting the subsequent steel plate.

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

[0006] A material stop mechanism for a bending machine, the material stop mechanism being fixedly connected to one side of the bending machine, the material stop mechanism comprising:

[0007] A bracket, one end of which is fixedly connected to a bending machine, a first sliding groove is provided on the bracket, a first slider is slidably connected in the first sliding groove, a drive plate is fixedly connected to the lower end of the first slider, a first threaded rod with a threaded connection is passed through the drive plate, and the two ends of the first threaded rod are rotatably connected to the bracket.

[0008] A movable plate is fixedly connected to the upper end of a first slider. At least one slide rod is fixedly connected vertically to the movable plate. A sliding sleeve is fitted onto the slide rod. A base plate is rotatably connected to the lower side of the sliding sleeve. Several rotating rollers are rotatably connected to the upper surface of the base plate. A baffle is fixedly connected to one end of the base plate near the sliding sleeve. A top plate is fixedly connected to the upper end of the baffle. A second threaded rod is threadedly connected to the top plate. A clamping plate is rotatably connected to the lower end of the second threaded rod. Several rotating rollers are rotatably connected to the lower surface of the clamping plate.

[0009] The principles and technical effects of the above technical solution are as follows:

[0010] Under the influence of gravity, the lower ends of the sliding sleeve and the base plate are both in contact with the moving plate, making the base plate horizontal. Simultaneously, the upper surface of the lower die on the bending machine is on the same horizontal plane as the uppermost point of the rotating roller on the base plate. This ensures that when the steel plate is placed on the lower die and its end rests on the rotating roller on the base plate, the steel plate remains horizontal. The drive source drives the first threaded rod to rotate, which in turn moves the drive plate. The drive plate moves the first slider along the first slide groove, which in turn moves the moving plate. The moving plate moves the baffle, adjusting the distance. Then, the second threaded rod... The auger drives the clamping plate downwards until the rotating roller on the clamping plate makes close contact with the steel plate. Then, it drives the upper die on the bending machine to move downwards to bend the steel plate. During the bending process, the two sides of the steel plate will curl upwards. As they curl upwards, they will drive the sliding sleeve to move upwards. At the same time, the base plate will rotate and remain parallel to the curled part of the steel plate. Meanwhile, the curled part of the steel plate will be pulled outwards. At this time, the rotating roller can reduce friction with the steel plate and reduce the wear of the steel plate. When the steel plate is bent, it can prevent the side of the steel plate from curling up and rubbing against the baffle, avoiding baffle wear and reducing the error caused by the subsequent steel plate limit.

[0011] In a preferred embodiment, the present invention can be further configured such that: a motor is fixedly connected to one end of the bracket away from the bending machine, and the output end of the motor is fixedly connected to the first threaded rod.

[0012] In a preferred embodiment, the present invention can be further configured such that: guide rods are provided on both sides of the first threaded rod, the two ends of the guide rods are fixedly connected to the bracket, and the guide rods pass through the drive plate so that the drive plate and the guide rods are slidably connected.

[0013] In a preferred embodiment, the present invention can be further configured such that the sliding rod is a rectangular long rod.

[0014] In a preferred embodiment, the present invention can be further configured such that: a first magnet block is fixedly connected to the upper end of the sliding sleeve near the baffle, and a second magnet block is fixedly connected to the upper side of the baffle.

[0015] In a preferred embodiment, the present invention can be further configured such that: a second sliding groove is provided vertically along the baffle, a second slider is slidably connected in the second sliding groove, and the second slider is fixedly connected to the clamping plate.

[0016] In a preferred embodiment, the present invention can be further configured such that a rotating component is fixedly connected to the upper end of the second threaded rod.

[0017] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0018] 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.

[0019] (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.

[0020] (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.

[0021] A threaded connection is a detachable connection in which threaded parts (or the threaded portion of the connected parts) are joined together to form a single unit.

[0022] A sliding connection refers to two objects that are in contact but not fixed, and can slide relative to each other.

[0023] A rotating connection is a connection between parts that allows the parts to rotate relative to each other.

[0024] The beneficial effects of this utility model are:

[0025] When the steel plate is bent, it can prevent the side of the steel plate from warping up and rubbing against the baffle, thus avoiding baffle wear and reducing the error caused by limiting the subsequent steel plate. Attached Figure Description

[0031] 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.

[0032] 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.

[0033] Based on the concept of this application, combined with Figures 1 to 4 This describes an embodiment of a bending machine stop mechanism. Specifically, the bending machine stop mechanism is constructed as a split structure, comprising components such as a stop mechanism 100 and a bending machine 200. Under the action of gravity, the lower ends of the sliding sleeve 108 and the lower ends of the base plate 109 are in contact with the moving plate 106, making the base plate 109 horizontal. Simultaneously, the upper end face of the lower die 201 on the bending machine 200 is on the same horizontal plane as the uppermost end of the rotating roller 110 on the base plate 109. This ensures that when a steel plate is placed on the lower die 201 and its end rests on the rotating roller 110 on the base plate 109, the steel plate is horizontal. A drive source drives the first threaded rod 105 to rotate, which in turn moves the drive plate 104. The drive plate 104 then moves the first slider 103 along the first slide groove 102, which in turn moves the moving plate 106. The moving plate 106 then moves the baffle plate 106. 11. Move and adjust the distance. Then, rotate the second threaded rod 113 to drive the clamping plate 114 to move down until the rotating roller 110 on the clamping plate 114 is in close contact with the steel plate. Then, drive the upper die 202 on the bending machine 200 to move down to bend the steel plate. During the bending process, the two sides of the steel plate will curl up. During the curling process, the sliding sleeve 108 will move up. At the same time, the bottom plate 109 will rotate and remain parallel to the curled part of the steel plate. At the same time, the curled part of the steel plate will be pulled away from the outside. At this time, the setting of the rotating roller 110 can reduce the friction with the steel plate and reduce the wear of the steel plate. When the steel plate is bent, it can avoid the side of the steel plate curling up and rubbing against the baffle, avoid baffle wear, and reduce the error caused by the subsequent steel plate limit.

[0034] like Figures 1 to 4As shown, a bending machine stop mechanism is provided. The stop mechanism 100 is fixedly connected to one side of the bending machine 200. The stop mechanism 100 includes:

[0035] A bracket 101 is fixedly connected to a bending machine 200 at one end. A first slide groove 102 is provided on the bracket 101. A first slider 103 is slidably connected in the first slide groove 102. A drive plate 104 is fixedly connected to the lower end of the first slider 103. A threaded first rod 105 is threaded through the drive plate 104. Both ends of the first threaded rod 105 are rotatably connected to the bracket 101.

[0036] A movable plate 106 is fixedly connected to the upper end of the first slider 103. At least one slide rod 107 is fixedly connected vertically along the upper edge of the movable plate 106. A sliding sleeve 108 is slidably connected to the slide rod 107. A base plate 109 is rotatably connected to the lower side of the sliding sleeve 108. Several rotating rollers 110 are rotatably connected to the upper surface of the base plate 109. A baffle 111 is fixedly connected to the end of the base plate 109 near the sliding sleeve 108. A top plate 112 is fixedly connected to the upper end of the baffle 111. A second threaded rod 113 is threadedly connected to the top plate 112. A clamping plate 114 is rotatably connected to the lower end of the second threaded rod 113. Several rotating rollers 110 are rotatably connected to the lower surface of the clamping plate 114.

[0037] In use, under the influence of gravity, the lower ends of the sliding sleeve 108 and the lower ends of the base plate 109 are in contact with the moving plate 106, making the base plate 109 horizontal. Simultaneously, the upper surface of the lower die 201 on the bending machine 200 is on the same horizontal plane as the uppermost end of the rotating roller 110 on the base plate 109. This ensures that when a steel plate is placed on the lower die 201 and its end rests on the rotating roller 110 on the base plate 109, the steel plate remains horizontal. The drive source drives the first threaded rod 105 to rotate, which in turn moves the drive plate 104. The drive plate 104 then moves the first slider 103 along the first slide groove 102, which in turn moves the moving plate 106. The moving plate 106 then moves the stop... The plate 111 moves and the distance is adjusted. Then, the second threaded rod 113 is rotated to drive the clamping plate 114 to move down until the rotating roller 110 on the clamping plate 114 is in close contact with the steel plate. Then, the upper die 202 on the bending machine 200 is driven to move down to bend the steel plate. During the bending process, the two sides of the steel plate will curl up. During the upward curling process, the sliding sleeve 108 will move up. At the same time, the bottom plate 109 will rotate and remain parallel to the curled part of the steel plate. At the same time, the curled part of the steel plate will be pulled away from the outside. At this time, the setting of the rotating roller 110 can reduce the friction with the steel plate and reduce the wear of the steel plate. When the steel plate is bent, it can avoid the side of the steel plate curling up and rubbing against the baffle, avoid baffle wear, and reduce the error caused by the subsequent steel plate limit.

[0038] In one embodiment of this utility model, a motor 115 is fixedly connected to the end of the bracket 101 away from the bending machine 200, and the output end of the motor 115 is fixedly connected to the first threaded rod 105. The motor 115 serves as a drive source to drive the first threaded rod 105 to rotate, thereby adjusting the distance of the baffle 111.

[0039] In one embodiment of this utility model, guide rods 116 are provided on both sides of the first threaded rod 105. The two ends of the guide rods 116 are fixedly connected to the bracket 101, and the guide rods 116 pass through the drive plate 104, so that the drive plate 104 and the guide rods 116 are slidably connected. The provision of guide rods 116 can improve the stability of the drive plate 104 when moving, thereby improving the stability of the moving plate 106 when moving.

[0040] In one embodiment of this utility model, the slide rod 107 is a rectangular long rod. This structure prevents the sliding sleeve 108 from rotating on the slide rod 107, so that the sliding sleeve 108 can only move up and down and cannot rotate.

[0041] In one embodiment of this utility model, a first magnet block 117 is fixedly connected to the upper end of the sliding sleeve 108 near the baffle 111, and a second magnet block 118 is fixedly connected to the upper side of the baffle 111. When the steel plate is not clamped, the first magnet block 117 and the second magnet block 118 are magnetically attracted to each other, so that the baffle 111 remains in a vertical state.

[0042] In one embodiment of this utility model, a second sliding groove 119 is vertically formed along the upper edge of the baffle 111, and a second slider 120 is slidably connected within the second sliding groove 119. The second slider 120 is fixedly connected to the clamping plate 114. This arrangement makes the clamping plate 114 more stable when moving up and down, and at the same time, ensures that the clamping plate 114 will not deflect.

[0043] In one embodiment of this utility model, a rotating component 121 is fixedly connected to the upper end of the second threaded rod 113. The rotating component 121 is provided so that the operator can rotate the rotating component 121 to drive the rotation of the second threaded rod 113, thereby driving the clamping plate 114 to move down and clamp the steel plate.
