Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically a positioning device for a security door panel shearing machine. Background Technology

[0002] In the operation of a shearing machine, the positioning device is a key component to ensure the shearing accuracy of the sheet metal. Its performance directly affects the processing quality of workpieces such as security door panels. At present, there are many types of positioning mechanisms for shearing machines on the market. Most of them achieve the positioning of sheet metal of different sizes through adjustable support structures to adapt to diverse processing needs.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN218224893U) discloses a positioning mechanism for a shearing machine, comprising a shearing machine body and a clamping assembly. A slide rail is mounted on the outer surface of the shearing machine body, a slider is mounted on the outer surface of the slide rail, and a longitudinal support arm is mounted on the outer surface of the slider. A length adjustment assembly for adjusting the length is located above the longitudinal support arm. The length adjustment assembly includes a horizontal support arm sleeve, an electric cylinder, and a horizontal support arm rod. The electric cylinder is mounted on the inner surface of the horizontal support arm sleeve, and the horizontal support arm rod is mounted on the outer surface of the electric cylinder. Compared to existing ordinary shearing machine positioning mechanisms, in this positioning mechanism, the longitudinal support arm can slide back and forth along the slide rail via the slider. After the electric cylinder is activated, it can push the horizontal support arm rod to slide left and right along the horizontal support arm sleeve, thereby changing the position of the pressure plate and the rubber liner to accommodate different sizes of sheet metal. This gives the shearing machine positioning mechanism a position adjustment function, making it suitable for different working conditions.

[0004] The aforementioned patented positioning mechanism still has certain limitations in practical applications. On the one hand, the positioning mechanism is located on the outside of the shearing machine body. During the operation of the shearing machine, operators or other equipment are prone to collisions with it, which can easily damage the positioning mechanism, affect its positioning accuracy and service life, and also pose certain safety hazards. On the other hand, the layout and adjustment range of its positioning structure are limited, and the positioning effect cannot cover the entire position of the panel, making it difficult to achieve comprehensive and stable positioning.

[0005] Therefore, this utility model provides a positioning device for a security door panel shearing machine to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved This utility model provides a positioning device for a security door panel shearing machine, which aims to solve the problems mentioned in the background art.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a positioning device for a security door panel shearing machine, comprising a shearing machine body, a top plate fixedly installed at the top of the shearing machine body, and cylinders fixedly installed at both ends inside the shearing machine body, a piston rod fixedly connected to the telescopic end of the cylinder, the piston rod penetrating the top plate, a positioning plate fixedly connected to the top of the piston rod, the positioning plate being located above the top plate, and a protective component provided at the bottom of the positioning plate for protecting the positioned security door panel.

[0008] As a preferred technical solution of this application, the protective component includes multiple sets of connecting rods fixedly installed at the bottom of the positioning plate, with springs fixedly connected to the ends of the multiple sets of connecting rods, and pressure plates fixedly connected to the ends of the springs away from the connecting rods.

[0009] As a preferred technical solution of this application, multiple sets of sleeves are fixedly installed on the top outer surface of the pressure plate. The multiple sets of sleeves are sleeved on the outside of the spring and the connecting rod to protect the spring and the connecting rod.

[0010] As a preferred technical solution of this application, multiple sets of rubber pads are fixedly installed at the bottom end of the pressure plate, and the rubber pads are evenly distributed along the length direction of the pressure plate.

[0011] As a preferred technical solution of this application, the top of the positioning plate is fixedly installed with multiple sets of fixing plates by bolts, and the interior of the positioning plate is fixedly installed with multiple sets of reinforcing ribs.

[0012] As a preferred technical solution of this application, multiple sets of limiting rods are slidably installed on the outer surface of the top plate. The multiple sets of limiting rods are symmetrically distributed on both sides of the piston rod, and a positioning plate is fixedly connected to the top of the multiple sets of limiting rods to guide and limit the movement of the positioning plate.

[0013] As a preferred technical solution of this application, multiple sets of support plates are fixedly installed inside the top plate, and the multiple sets of support plates are used to support the top plate.

[0014] (III) Beneficial Effects 1. In this device, the cylinder is installed inside the main body of the shearing machine, and the piston rod passes through the top plate and connects to the positioning plate. The overall structure is more compact, and most of the positioning-related components are located above the top plate and inside the main body of the shearing machine, reducing the number of exposed parts and greatly reducing the probability of collision with operators or other equipment. This not only protects the positioning device itself and reduces the risk of damage, but also improves the safety of operation. 2. By using a positioning plate and its bottom protective components, the pressure plate can make large-area contact with the panel when the positioning plate descends. During positioning, the elasticity of the spring allows the pressure plate to gently press against the panel, and the even distribution of the rubber pads ensures that the positioning pressure covers a wider area of ​​the panel. This achieves more comprehensive and stable positioning of the panel, effectively solving the problem of limited positioning range in existing mechanisms, preventing panel offset during shearing, and ensuring shearing accuracy.

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides a positioning device for a security door panel shearing machine, such as... Figures 1-5 As shown, the shearing machine includes a main body 1, a top plate 2 fixedly installed at the top of the main body 1, and cylinders 31 fixedly installed at both ends inside the main body 1. A piston rod 3 is fixedly connected to the telescopic end of the cylinder 31, and the piston rod 3 passes through the top plate 2. A positioning plate 5 is fixedly connected to the top of the piston rod 3. The positioning plate 5 is located above the top plate 2. The cylinder 31 drives the positioning plate 5 to move up and down, which can ensure the consistency and accuracy of the positioning action and improve the positioning efficiency. A protective component is provided at the bottom of the positioning plate 5 to protect the anti-theft door panel of the positioning.

[0019] The protective component includes multiple sets of connecting rods 72 fixedly installed at the bottom of the positioning plate 5. The ends of the multiple sets of connecting rods 72 are fixedly connected to springs 71, and the ends of the springs 71 away from the connecting rods 72 are fixedly connected to pressure plates 51. In use, the connecting rods 72 provide stable connection support for the springs 71 and the pressure plates 51. The elastic characteristics of the springs 71 make the positioning process gentler when the pressure plates 51 contact the panel, effectively protecting the appearance quality of the panel.

[0020] Among them, multiple sets of sleeves 7 are fixedly installed on the top outer surface of the pressure plate 51. The multiple sets of sleeves 7 are sleeved on the outside of the spring 71 and the connecting rod 72 to protect the spring 71 and the connecting rod 72. The sleeves 7 can isolate the spring 71 and the connecting rod 72 from the external environment, preventing iron filings, dust and other debris generated during the processing from adhering to the spring 71 and the connecting rod 72, and avoiding affecting their normal extension and contraction function.

[0021] Multiple sets of rubber pads 53 are fixedly installed at the bottom of the pressure plate 51. The rubber pads 53 are evenly distributed along the length of the pressure plate 51. The rubber material has good elasticity and wear resistance, which can further enhance the buffer protection of the panel. At the same time, the high friction of the rubber can increase the friction between the rubber and the panel, effectively preventing the panel from sliding during the shearing process and ensuring the shearing accuracy.

[0022] The top of the positioning plate 5 is fixedly installed with multiple sets of fixing plates 52 by bolts, and multiple sets of reinforcing ribs 54 are fixedly installed inside the positioning plate 5. The reinforcing ribs 54 improve the overall structural strength and rigidity of the positioning plate 5 from the inside, making the positioning plate 5 less prone to bending or breaking when positioning pressure is applied, ensuring the structural integrity of the positioning plate 5, and ensuring the stability and reliability of the positioning action.

[0023] Among them, multiple sets of limiting rods 4 are slidably installed on the outer surface of the top plate 2. The multiple sets of limiting rods 4 are symmetrically distributed on both sides of the piston rod 3, and the top of the multiple sets of limiting rods 4 are fixedly connected to positioning plates 5, which are used to guide and limit the movement of positioning plates 5, prevent positioning plates 5 from shifting left or right or rotating during movement, ensure that positioning plates 5 can be accurately aligned with the panel when they descend, and improve the positioning accuracy.

[0024] The top plate 2 has multiple sets of support plates 6 fixedly installed inside. These support plates 6 are used to support the top plate 2, preventing it from bending and deforming due to excessive force, ensuring the flatness of the top plate 2, providing a stable foundation for the panel, and indirectly ensuring the accuracy of positioning and cutting.

[0025] Working principle: First, the security door panel to be processed is placed stably on the top plate 2 at the top of the shearing machine body 1, ensuring that the edge of the panel to be cut is aligned with the preset cutting line. At this time, multiple sets of support plates 6 inside the top plate 2 provide stable support for the entire top plate structure, ensuring the stability of the panel placement. Next, the two sets of cylinders 31 installed at both ends inside the main body 1 of the shearing machine are started. The extension and retraction ends of the cylinders 31 drive the piston rod 3 to move downward. Since the top of the piston rod 3 is fixedly connected to the positioning plate 5, and multiple sets of limit rods 4 are symmetrically distributed on both sides of the piston rod 3 and fixed to the top of the positioning plate 5, the positioning plate 5 descends smoothly along the guide direction of the limit rods 4 under the drive of the piston rod 3. The setting of the limit rods 4 effectively prevents the positioning plate 5 from shifting or shaking during the descent, ensuring the accuracy of the positioning action. As the positioning plate 5 descends, its bottom protective component moves down synchronously. When the pressure plate 51 in the protective component approaches the surface of the security door panel, the spring 71 connected to the top of the pressure plate 51 via the connecting rod 72 begins to be gradually compressed. The elasticity of the spring 71 allows the pressure plate 51 to contact and press the panel with a gentle and gradually increasing pressure, avoiding damage to the panel surface that may be caused by rigid compression. At the same time, multiple sets of sleeves 7 fixed to the outer surface of the top of the pressure plate 51 are fitted over the spring 71 and the connecting rod 72 to prevent external debris from entering and affecting the normal operation of the spring 71 during its extension and retraction, and also to prevent damage to the spring 71 and the connecting rod 72 due to accidental collisions. When the pressure plate 51 fully presses the panel, the multiple sets of rubber pads 53 fixedly installed at its bottom end are in close contact with the panel surface. The rubber pads 53 not only further enhance the protection of the panel surface and prevent indentations, but also increase the friction between the pressure plate 51 and the panel by utilizing the high friction characteristics of the rubber material, effectively preventing the panel from sliding during the subsequent shearing process.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
