Description

Technical Field

[0001] The present invention relates to the technical field of shaving blade processing, and specifically to an automatic bending device for shaving blades. Background Technique

[0002] A safety razor, also known as a shaving razor, is a tool for shaving beards and belongs to a self-service tool, mostly used by adult men. It is mainly divided into two types: electric razors and manual razors. Among them, the manual razor is more popular among users because of its lower price and cleaner beard shaving compared to electric razors. A manual razor generally consists of a blade and a hoe-shaped knife holder. The knife holder is made of aluminum, stainless steel, copper, or plastic, etc.; the blade is made of carbon steel, alloy steel, etc. To ensure sharpness and durability, the edge of the blade is mostly treated with metal or chemical coating. The blade of a manual razor is generally composed of 6-8 shaving blades. To ensure clean shaving, the blades need to be bent to form the edge.

[0003] Currently, the shaving blades on the market are first cut into the size of the blades, then bent and formed into cutting edges by a bending device, and finally the blades are taken out manually and installed on the knife holder. The disadvantages of manual installation are as follows: the blades are small in size and have sharp edges, which are easy to hurt hands; only one blade can be installed manually each time, which greatly reduces the production efficiency. At the same time, manual installation is time-consuming and laborious, with a large labor intensity and a high defective rate of products. Therefore, the applicant has improved and modified the existing bending device for shaving blades. Summary of the Invention

[0038] Please refer to Figure 4, the bending device 4 in the figure includes a bending bottom plate 41 fixedly installed on the workbench 2, and a second slide rail 42 arranged in parallel on the bending bottom plate 41. A bending lower die assembly 43 is arranged inside the second slide rail 42 on the bending bottom plate 41, and support columns 44 are arranged at the four corners of the bending bottom plate 41. A driving fixed plate 45 is fixedly installed at one end of the support column 44 away from the bending bottom plate 41, and a driving assembly 46 is fixedly installed on the driving fixed plate 45. A second slider 47 is slidably arranged on the second slide rail 42, and a bending upper die assembly 48 is fixedly installed on the second slider 47. A second push-pull cylinder 410 for driving the bending upper die assembly 48 to move along the length direction of the second slide rail 42 is also arranged on the second slide rail 42. The bending upper die assembly 48 cooperates with the bending lower die assembly 43 to bend the shaving blade. The bending device 4 further includes a shaving blade flipping mechanism 49, which is fixedly installed on the bending bottom plate 41 and is used to flip the shaving blade by 90°.

[0039] Please refer to again Figure 4 , the above automatic shaving blade loading device 3 moves the unbent shaving blade to the bending lower die assembly 43. The bending upper die assembly 48 cooperates with the bending lower die assembly 43 under the action of the driving assembly 46 to bend the unbent shaving blade to obtain a bent shaving blade. Then, the second push-pull cylinder 410 pushes the bending upper die assembly 48 to slide along the length direction of the second slide rail 42, so that the bending lower die assembly 43 and the bending upper die assembly 48 are misaligned, facilitating the above-mentioned shaving blade grasping mechanism 5 to move the bent shaving blade on the bending lower die assembly 43 to the shaving blade flipping mechanism 49, and the shaving blade flipping mechanism 49 flips the bent shaving blade by 90° for subsequent assembly.

[0040] Please refer to Figure 5 , the bending lower die assembly 43 in the figure includes a front buffer backing plate 431, a bending lower die fixing plate 432, and a rear buffer backing plate 433.

A bending lower die 434 is fixedly installed on the bending lower die fixing plate 432.

[0041] Please refer to again Figure 5 , by adopting the above technical solution, the front buffer backing plate 431 is used to receive the unbent shaving blade pushed in by the above automatic shaving blade loading device 3, the bending lower die 434 is used to cooperate with the above bending upper die assembly 48 to bend the unbent shaving blade, and the rear buffer backing plate 433 is used to place the bent shaving blade, facilitating the grasping of the above shaving blade grasping mechanism 5.

[0042] Please refer to again Figure 4, in the figure, the driving component 46 consists of a front suction shaving blade cylinder 461, a bending cylinder 462, and a rear suction shaving blade cylinder 463. The bending cylinder 462 is located between the front suction shaving blade cylinder 461 and the rear suction shaving blade cylinder 463. The front suction shaving blade cylinder 461, the bending cylinder 462, and the rear suction shaving blade cylinder 463 are all fixedly installed on the driving fixed plate 45. The output ends of the front suction shaving blade cylinder 461, the bending cylinder 462, and the rear suction shaving blade cylinder 463 all penetrate the driving fixed plate 45 from top to bottom and are in contact connection with the bending upper die assembly 48. When the output ends of the front suction shaving blade cylinder 461, the bending cylinder 462, and the rear suction shaving blade cylinder 463 extend simultaneously, the driving bending upper die assembly 48 contacts the bending lower die assembly 43 to complete the bending operation process.

[0043] Please refer to Figure 6 and Figure 7 , in the figure, the bending upper die assembly 48 includes a bending sliding plate 481 fixedly installed on the second slider 47. Limiting baffles 4812 are respectively arranged on both sides of the bending sliding plate 481. A first backing plate 482 and a second backing plate 483 are fixedly installed on the upper end surface of the bending sliding plate 481. A first pressing plate 484 and a second pressing plate 485 are respectively arranged above the first backing plate 482 and the second backing plate 483. A front suction head fixing seat 486 and a bending upper die fixing seat 487 are respectively fixedly installed on the first pressing plate 484 and the second pressing plate 485. The front suction head fixing seat 486 penetrates the first backing plate 482 and the bending sliding plate 481 from top to bottom and is fixedly connected to the front shaving blade suction head 488. The bending upper die fixing seat 487 penetrates the second backing plate 483 and the bending sliding plate 481 from top to bottom and is fixedly connected to the bending upper die 489. A rear suction head fixing seat 4810 is also fixedly installed on the second pressing plate 485. A rear shaving blade suction head 4811 is fixedly installed on the rear suction head fixing seat 4810. The bending upper die assembly 48 also includes a return spring, which consists of a first return spring 4813 and a second return spring 4814. The first return spring 4813 is located between the first pressing plate 484 and the first backing plate 482, and the second return spring 4814 is located between the second pressing plate 485 and the second backing plate 483.

[0044] Please refer to again Figure 4 , Figure 6 and Figure 7, when the bending sliding plate 481 can move back and forth along the length direction of the second slide rail 42 under the action of the second push-pull cylinder 410, it can further drive the front shaving blade suction head 488, the bending upper die 489 and the rear shaving blade suction head 4811 to move synchronously. When the front shaving blade suction head 488 moves directly above the above-mentioned front buffer backing plate 431, the bending upper die 489 and the rear shaving blade suction head 4811 are respectively located directly above the bending lower die 434 and the rear buffer backing plate 433. The front shaving blade suction cylinder 461 presses down on the first pressing plate 484, and the bending cylinder 462 and the rear shaving blade suction cylinder 463 simultaneously press down on the second pressing plate 485. At this time, both the first return spring 4813 and the second return spring 4814 are compressed. At the same time, the front shaving blade suction head 488 contacts the front buffer backing plate 431 and adsorbs the unbent shaving blade on the front buffer backing plate 431. The bending upper die 489 contacts the bending lower die 434 and bends the unbent shaving blade on the bending lower die 434. The rear shaving blade suction head 4811 contacts the rear buffer backing plate 433 and adsorbs the bent shaving blade on the rear buffer backing plate 433. At this time, the output ends of the front shaving blade suction cylinder 461, the bending cylinder 462 and the rear shaving blade suction cylinder 463 are separated from the first pressing plate 484 and the second pressing plate 485, and the first return spring 4813 and the second return spring 4814 are reset, driving the front shaving blade suction head 488, the bending upper die 489 and the rear shaving blade suction head 4811 to reset. At this time, the second push-pull cylinder 410 pushes the bending upper die assembly 48 towards one end of the shaving blade flipping mechanism 49. When the front shaving blade suction head 488 is located directly above the bending lower die 434, the bending upper die 489 is located directly above the rear buffer backing plate 433, and the rear shaving blade suction head 4811 is located directly above the shaving blade flipping mechanism 49. The bending cylinder 462 and the rear shaving blade suction cylinder 463 respectively press down on the first pressing plate 484 and the second pressing plate 485. The front shaving blade suction head 488 places the unbent shaving blade on the bending lower die 434, and the rear shaving blade suction head 4811 places the bent shaving blade on the shaving blade flipping mechanism 49. After that, the first return spring 4813 and the second return spring 4814 are reset again. When the second push-pull cylinder 410 drives the bending upper die assembly 48 to reset, the automatic upper shaving blade device 3 pushes the unbent shaving blade onto the front buffer backing plate 431 again. By repeating this process, automatic feeding, bending and discharging are achieved.

[0045] Please refer to Figure 8 and Figure 9, the shaving blade flipping mechanism 49 in the figure includes a linear slide rail 491 fixedly installed on the bending bottom plate 41. A limit stop 499 is provided on the linear slide rail 491, and shaving blade bending and flipping assemblies are provided on both sides of the limit stop 499 on the linear slide rail 491. The shaving blade bending and flipping assembly includes a slide plate 492 slidably arranged on the linear slide rail 491 and a flipping drive cylinder 493 arranged at one end of the linear slide rail 491. The output end of the flipping drive cylinder 493 is in contact connection with the slide plate 492. A linear tooth 494 is provided on one side of the linear slide rail 491. A rotating shaft 495 is installed on the slide plate 492. A gear 496 is installed at one end of the rotating shaft 495. The gear 496 meshes with the linear tooth 494. A shaving blade placement plate 497 for placing shaving blades is installed on the rotating shaft 495. Magnets 498 are provided on the shaving blade placement plate 497.

[0046] Please refer to again Figure 8 and Figure 9 , when the above-mentioned post-shaving blade suction head 4811 places the bent shaving blade on the shaving blade placement plate 497, the magnet 498 adsorbs the shaving blade. It should be noted here that the shaving blade in this embodiment is carbon steel with a relatively high iron content, so it can be adsorbed by the magnet 498. The flipping drive cylinder 493 pushes the slide plate 492 to move back and forth along the length direction of the linear slide rail 491, further driving the rotating shaft 495 and the gear 496 on the rotating shaft 495 to move. When the gear 496 moves, it meshes with the linear tooth 494, and further drives the gear 496 to rotate. The shaving blade placement plate 497 and the shaving blades placed on the shaving blade placement plate 497 will also rotate 90°, realizing the automatic flipping of the shaving blades.
