Description

Technical Field

[0001] The invention relates to the technical field of olefin material shearing, in particular to a smooth shearing forming die based on a full polyolefin bulletproof composite material. Background Art

[0002] The smooth shear forming die based on all-polyolefin bulletproof composite material is a die used to manufacture bulletproof materials. All-polyolefin is a high-strength, heat-resistant and chemical-resistant material commonly used to manufacture bulletproof materials and other durable materials. Bulletproof materials are usually composed of multiple layers of composite materials, including all-polyolefin film.

[0003] A smooth shearing forming die is a tool used to shear materials into specific shapes. It is usually made of metal or other wear-resistant materials and has a pair of cutting blades. It achieves cutting by applying shear force to the material. When manufacturing bulletproof materials, a smooth shearing forming die can accurately cut the material after full polyolefin over-compounding and other processes according to the required shape and size to produce bulletproof products that meet the requirements.

[0004] The existing mold manufacturing process usually needs to take into account the properties of all-polyolefins, such as hardness, toughness and wear resistance. At the same time, the mold design also needs to be optimized according to the requirements of bullet-proof products to ensure accuracy and stability during the cutting process. Manufacturing high-quality smooth shearing molding molds is crucial for the production of high-performance bullet-proof materials. In the existing shearing process, the material needs to be straightened to ensure accuracy. However, due to tension and the flexibility of the material itself, the shear position is often inaccurate during the straightening and shearing process, and even arc shearing may occur. In addition, the material that naturally hangs down after shearing is not conducive to timely observation by staff to judge the goodness of the shearing effect, and it is also not convenient for the recycling process.

Beneficial effects

[0013] The present invention provides a smooth shearing forming die based on an all-polyolefin bulletproof composite material.

[0014] (2) The smooth shearing forming die based on the all-polyolefin bulletproof composite material completes the cutting process when the cutting component is in a horizontal position. When the cutting process is completed, the magnetic strip and the counterweight magnet are attracted together, and the other side of the olefin material sheet is limited at the same time. By setting the pressing plate, the shearing position of the olefin material sheet can be leveled and pressed, reducing the generation of fuzz and burrs. In addition, the two sides of the olefin material sheet can be limited and fixed at the same time through the above process, effectively preventing the olefin material sheet from loosening, ensuring the accuracy of shearing.

[0015] (3) The smooth shearing forming die based on the all-polyolefin bulletproof composite material realizes the preliminary limiting of the olefin material sheet during the downward shearing process of the cutting component to ensure the accuracy of the shearing position, and automatically realizes the synchronous limiting and fixing process of the shearing two sides of the olefin material sheet through the shearing process of the cutting component, thereby ensuring the shearing effect and preventing the olefin material sheet from loosening or arc shearing. In addition, the burrs at the shearing cut of the olefin material sheet are effectively reduced by stretching the limiting and pressing plate to process the shearing cut of the olefin material sheet, which is convenient for the later processing of the cut of the olefin material sheet, reduces the subsequent processing process, and increases the shearing production efficiency.

[0021] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0022] When the smooth shearing forming die is used to shear the olefin material sheet 6, the olefin material sheet 6 is first wound in the order of unwinding roller 7 - tensioning roller 5 - cutting assembly 2 - tensioning roller 5 - winding roller 9, and the appropriate tensioning force of the olefin material sheet 6 is selected by stretching the two ends of the olefin material sheet 6, and the position of the olefin material sheet 6 is placed according to the shearing mark marked on the olefin material sheet 6 in advance; Then turn on the pneumatic pump 3. When the pneumatic pump 3 is running, it drives the connecting block 4 to move downward. During the initial downward movement of the connecting block 4, the cross plate 18 can be driven downward, thereby driving the elastic telescopic rod 19 to move downward, and the connecting plate 20 moves downward accordingly. When the connecting plate 20 moves downward, the second toothed plate 31 on the side wall of the connecting plate 20 moves downward, thereby driving the transmission gear 30 to rotate. When the transmission gear 30 rotates, it drives the first toothed plate 29 on the other side wall of the transmission gear 30 to move upward, and through the first toothed plate 29 drives the synchronization rod 27 to move upward, and at the same time pulls the multiple movable rods 25 and the second pressing block 26 to move upward, and the lower end of the movable rod 25 slides out of the movable cavity 24 until the first pressing block 21 and the second pressing block 26 firmly clamp the olefin material sheet 6 in the middle, thereby limiting the position of the olefin material sheet 6. As the connecting block 4 drives the cutting assembly 2 to continue to move downward, the elastic telescopic rod 19 itself shortens, making the first pressing block 21 and the second pressing block 26 clamp the olefin material sheet 6 more stably. When the cutting assembly 2 moves downward, the olefin material sheet 6 after the preliminary limit is sheared. During the downward movement of the cutting assembly 2, when the cutting assembly 2 moves down to a certain height, the counterweight magnet 11 at the lower end of the rotating piece 10 attracts the magnetic strip 13, thereby attracting the magnetic strip 13 to move upward, stretching the telescopic rod 15 and the spring 16. When the cutting assembly 2 is in a horizontal position, the cutting process is completed. When the cutting process is completed, the magnetic strip 13 and the counterweight magnet 11 are adsorbed together, and the other side of the olefin material sheet 6 is limited at the same time. By setting the pressing plate 17, the shearing position of the olefin material sheet 6 can be leveled and pressed, reducing the generation of fluff and burrs. In addition, the above process can simultaneously limit and fix both sides of the olefin material sheet 6, effectively preventing the olefin material sheet 6 from loosening, ensuring the accuracy of shearing, and at the same time, the well-limited olefin material sheet 6 is convenient for the staff to observe the shearing effect, and also convenient for collecting the sheared olefin material sheet 6. Through the above structure, the olefin material sheet 6 is preliminarily limited during the downward shearing process of the cutting component 2 to ensure the accuracy of the shearing position, and the synchronous limiting and fixing process of the shearing sides of the olefin material sheet 6 is automatically realized through the shearing process of the cutting component 2, thereby ensuring the shearing effect and preventing the olefin material sheet 6 from loosening or arc shearing. In addition, the burrs at the shearing cut of the olefin material sheet 6 are effectively reduced by stretching the limiting and pressing plate 17 to process the shearing cut of the olefin material sheet 6, which is convenient for the later processing of the cut of the olefin material sheet 6, reducing the subsequent processing process and increasing the shearing production efficiency.
