Abstract
Description
Technical Field
[0001] The utility model relates to the field of plate shears, in particular to a plate shear with a protection structure. Background Technique
[0002] A plate shear is a machine that uses one blade to move reciprocally in a straight line relative to another blade to shear metal plates. It relies on the moving upper blade and the fixed lower blade, with a reasonable blade gap, to apply a shearing force to metal plates of various thicknesses, causing the plates to break and separate according to the required dimensions. The plate shear belongs to a type of forging machinery, and its main function is in the metal processing industry. The products are widely applicable to industries such as aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automobiles, electricity, electrical appliances, and decoration to provide the required special machinery and complete sets of equipment.
[0003] Existing plate shears can process metal plates of various thicknesses and widths, perform straight cutting from thin plates to thick plates, and can also adjust the shearing angle to ensure a smoother shearing surface, better straightness and parallelism. However, the existing plate shears use linear motors and pneumatic clamps to displace the workpiece. But when the workpiece completes the final cutting, the last piece of scrap is clamped back to the placement panel by the pneumatic clamp and manually placed into the feeding slot. This operation process is too cumbersome, reducing the usability of the plate shear. Therefore, there is an urgent need to design a plate shear that is easy to place the scrap. Content of the Utility Model
[0004] Based on this, the purpose of the present utility model is to provide a plate shear with a protection structure to solve the technical problem of the cumbersome process of placing the scrap.
[0005] To achieve the above purpose, the present utility model provides the following technical solution: A plate shear with a protection structure, including a device main body and a workpiece. One side of the device main body is provided with a placement surface. The bottom of the placement surface is provided with an electric push rod. The front end of the electric push rod is provided with a sliding seat. The top of the sliding seat is provided with a placement cylinder. A placement groove is opened on the surface of the placement surface. The placement cylinder is arranged inside the placement groove. A spring is arranged inside the placement cylinder. The top of the spring is provided with a sliding piece.
[0006] By adopting the above technical solution, first, the workpiece has completed cutting, and at the same time, the pneumatic clamp releases the last piece of scrap, causing the last piece of scrap to be placed on the placement surface. At this time, the sliding piece is displaced above the placement cylinder and the placement groove due to the elastic force of the spring. Then, the electric push rod pushes the sliding seat to perform a linear displacement. At this time, the placement cylinder and the sliding piece move towards the direction of the device main body, pushing the last piece of scrap into the feeding slot. At this time, the workpiece has completed cutting and is placed in the feeding slot. This operation process is simple and convenient.
[0007] Furthermore, the top surface of the sliding piece is of an inclined surface structure, and the spring is used for the reset of the sliding piece.
[0008] By adopting the above technical solution, the spring is arranged in the reset system of the sliding piece, ensuring that the sliding piece can quickly and accurately return to its initial position after each movement. Through the release of its elastic potential energy, the spring exerts a continuous and controllable restoring force on the sliding piece, which helps to improve the action coherence and service life of the entire mechanism.
[0009] Furthermore, a cutting assembly is provided at the top of the device body, and protective fences are provided at both the front and rear ends of the cutting assembly.
[0010] By adopting the above technical solution, firm and considerate protective fences are added at both the front and rear ends of the cutting assembly. These protective fences are not only structurally strong to resist accidental collisions, effectively preventing operators or surrounding personnel from accidentally contacting the high-speed rotating cutting parts, but also greatly improving the safety of the working environment.
[0011] Furthermore, linear motors are provided on both sides of the placement surface, and guide grooves are provided at the tops of the linear motors.
[0012] By adopting the above technical solution, high-performance linear motors are configured on both sides of the placement surface. The application of linear motors enables the shearing machine to achieve faster, more accurate and smoother linear motion, greatly improving the dynamic response ability and positioning accuracy of the equipment. Linear motors directly convert electrical energy into linear motion, reducing mechanical losses and improving energy efficiency.
[0013] Furthermore, a pneumatic fixture is provided at the top of the guide groove.
[0014] By adopting the above technical solution, this arrangement at the top of the guide groove enables the pneumatic fixture to move precisely along the guide groove, perfectly synchronized with the linear motion of the linear motor, not only improving the processing accuracy, but also greatly enhancing the automation degree and continuous production ability of the processing process.
[0015] Furthermore, a material discharge groove is provided at the back of the device body, and a weight sensor is provided at the bottom of the material discharge groove for monitoring the stacking situation of the goods position.
[0016] By adopting the above technical solution, a high-precision weight sensor is built into the bottom of the material discharge groove. By precisely measuring the weight change of the materials in the material discharge groove, when an abnormal stacking situation occurs, the system can automatically trigger an alarm to remind the staff to intervene, effectively preventing overloading or jamming problems and ensuring the smoothness and safety of the production process.
[0017] Furthermore, an alarm is provided on the surface of the device body, and the alarm and the weight sensor are electrically connected to an external power source.
[0018] By adopting the above technical solution, an alarm is installed at a prominent position on the surface of the device body. This design aims to quickly respond to abnormal signals from within the system, ensuring operational safety and production efficiency. The alarm usually uses a high-decibel sound or a combination of flashing lights to clearly convey warning information even in a noisy industrial environment, immediately attracting the attention of the operator.
[0019] In summary, the present utility model mainly has the following beneficial effects:
[0020] 1. In the present utility model, through the electric push rod, first, the workpiece has been cut, and at the same time, the pneumatic fixture releases the last piece of surplus material, so that the last piece of surplus material is placed on the placement surface. At this time, the sliding piece is displaced above the placement cylinder and the placement groove due to the elastic force of the spring. Then, the electric push rod pushes the sliding seat to perform a linear displacement. At this time, the placement cylinder and the sliding piece are displaced towards the direction of the device body, pushing the last piece of surplus material into the material discharge groove. At this time, the workpiece has been cut and placed in the material discharge groove. This operation process is simple and convenient.
[0021] 2. In the present utility model, by setting a warning device, a weight sensor is arranged at the bottom of the material discharge groove, and the alarm of the weight sensor is arranged on one side surface of the device body, so that the operator can also see the alarm light at the operation position, avoiding the situation that the operator cuts the workpiece in front of the device body and cannot see the placement in the material discharge groove, enabling the operator to know the placement situation of the material discharge groove behind the placement body in real time.

At the same time, the pneumatic fixture 7 releases the last piece of surplus material, and the last piece of surplus material is placed on the placement surface 4. At this time, the sliding piece 16 is displaced above the placement cylinder 13 and the placement groove 11 due to the elastic force of the spring 15. Then, the electric push rod 12 pushes the sliding seat 14 to perform a linear displacement. At this time, the placement cylinder 13 and the sliding piece 16 are displaced towards the direction of the device main body 1, and the last piece of surplus material is pushed into the feeding groove 10. At this time, the workpiece 8 has been cut and placed in the feeding groove 10. This operation process is simple and convenient, does not require manual operation, and reduces the labor cost.
[0031] Referring to Figure 3 、 Figure 4 , further, the top surface of the sliding piece 16 is of an inclined surface structure. The spring 15 is used for the reset of the sliding piece 16. The spring 15 is arranged in the reset system of the sliding piece 16, ensuring that the sliding piece 16 can quickly and accurately return to the initial position after each movement. Through the release of its elastic potential energy, the spring 15 applies a continuous and controllable restoring force to the sliding piece 16, which helps to improve the action coherence and service life of the entire mechanism, reduces wear or failures that may be caused by poor reset, ensures the long-term stable operation of the equipment, and improves work efficiency and system reliability.
[0032] Referring to Figure 1 、 Figure 2 、 Figure 3, a cutting assembly 2 is provided at the top of the device main body 1. Protective fences 3 are provided at both the front and rear ends of the cutting assembly 2. At both the front and rear ends of the cutting assembly 2, sturdy and considerate protective fences 3 are additionally provided. These protective fences 3 are not only structurally strong to resist accidental collisions and effectively prevent operators or surrounding personnel from accidentally touching the high-speed rotating cutting parts, greatly enhancing the safety of the working environment. The design of the protective fences 3 also takes into account the ventilation and heat dissipation performance to avoid the high temperature generated during cutting from affecting the device main body or other sensitive components.
[0033] Refer to Figure 1 , Figure 2 , Figure 3 , linear motors 5 are provided on both sides of the placement surface 4. Guide grooves 6 are provided at the top of the linear motors 5. High-performance linear motors 5 are configured on both sides of the placement surface 4. The application of the linear motors 5 enables the shearing machine to achieve faster, more accurate and stable linear motion, greatly enhancing the dynamic response ability and positioning accuracy of the equipment. The linear motors 5 directly convert electrical energy into linear motion, reducing mechanical losses and improving energy efficiency. The guide grooves 6 provide an accurate guiding path for the pneumatic clamps 7 placed on them, ensuring the straightness of motion and repeat positioning accuracy, and effectively reducing friction and wear, extending the service life of the equipment.
[0034] Refer to Figure 1 , Figure 2 , Figure 3 , a pneumatic clamp 7 is provided at the top of the guide groove 6. This arrangement at the top of the guide groove 6 enables the pneumatic clamp 7 to move precisely along the guide groove 6, perfectly synchronized with the linear motion of the linear motor 5, not only improving the processing accuracy but also greatly enhancing the automation degree and continuous production ability of the processing process. Compared with traditional mechanical clamps, the pneumatic clamp 7 has lower maintenance costs, is easy to operate, and has good environmental protection characteristics.
[0035] Refer to Figure 2 , a material discharge groove 10 is provided at the back of the device main body 1. A weight sensor is provided at the bottom of the material discharge groove 10 for monitoring the stacking situation of the goods position. A high-precision weight sensor is built into the bottom of the material discharge groove 10. The weight sensor accurately measures the weight change of the materials in the material discharge groove. When an abnormal stacking situation occurs, the system can automatically trigger an alarm to remind the staff to intervene, effectively preventing overloading or blocking problems, ensuring the smoothness and safety of the production process, optimizing inventory management, and reducing material costs.
[0036] Embodiment 2:
[0037] Refer to Figure 3 , Figure 4, an alarm 9 is provided on the surface of the device main body 1. The alarm 9 and the weight sensor are electrically connected to an external power supply. An alarm 9 is installed at a prominent position on the surface of the device main body 1. This design aims to quickly respond to abnormal signals from within the system, ensuring operation safety and production efficiency. The alarm 9 usually uses a high-decibel sound or a combination of flashing lights to clearly transmit warning information even in a noisy industrial environment, immediately attracting the attention of the operator. It can not only effectively prevent equipment damage caused by overload but also promptly detect and handle potential problems in the production process, ensuring the stable operation of the production line.
[0038] The implementation principle of the present utility model is as follows: First, place the workpiece 8 on the placement surface 4, then use the pneumatic fixture 7 to clamp and fix the workpiece 8. After that, the pneumatic fixture 7 slides through the linear motor 5 in the guide groove 6. After displacement to a certain position, the cutting assembly 2 cuts the workpiece 8. At this time, since the downward pressure of the workpiece 8 is greater than the elastic force of the spring 15, the sliding piece 16 displaces downward. When the workpiece 8 is cut to the last remaining piece of scrap, at this time the sliding piece 16 releases the downward pressure of the workpiece 8 on it, and displaces upward with the elastic force of the spring 15. And the pneumatic fixture releases the clamping limit on the last piece of scrap. At this time, the acting force of the electric push rod 12 pushes the slide seat 14 forward, causing the sliding piece 16 to apply a thrust to the last piece of scrap, resulting in the last piece of scrap entering the material discharge groove 10.
[0039] Parts not involved in the present utility model are the same as or can be implemented using existing technologies, and will not be elaborated here.
[0040] Although the embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model and are not limitations thereof.
