Description

Technical Field

[0001] The invention relates to a polishing device for producing stainless steel fasteners, belonging to the technical field of stainless steel fastener production. Background Art

[0002] Stainless steel fasteners are a term that encompasses a wide range of products. Due to their aesthetic appeal, durability, and excellent corrosion resistance, they are often used as key components in high-end machinery and equipment. Bidirectional threaded stainless steel rods are a key specification for these fasteners. However, during the production process, these stainless steel fasteners are prone to surface defects such as burrs, which not only affect their appearance but can also reduce their performance. Therefore, to ensure the quality of stainless steel fasteners, they are typically polished.

[0003] Currently, there are two main polishing technologies on the market. The first method is to use a grinding wheel to polish stainless steel fasteners. Although this method can achieve certain results, it often requires frequent turning of the workpiece and replacement of materials during operation, which not only increases labor intensity but also prolongs the time of the entire polishing process. Another common polishing method is to use the friction generated between granular abrasives and stainless steel fasteners to remove surface defects. Although this method simplifies the operation process to a certain extent, due to the hardness characteristics of stainless steel itself, some stubborn burrs are difficult to completely remove, resulting in slight unevenness in the finished product after polishing, which in turn affects the final product effect and processing efficiency.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] Example 1: Figures 1-6 As shown, a polishing device for manufacturing stainless steel fasteners is provided, comprising a base cabinet 1, a table 2 mounted on the upper end of the base cabinet 1, the table 2 providing a mounting carrier for components such as a feeding device, and the feeding device being arranged on the upper right end of the table 2, the stainless steel fasteners being fed one by one in an orderly manner through the feeding device, the feeding device being capable of using a vibrating plate 3, and two mounting plates 42 being symmetrically mounted on the upper end of the table 2, the two mounting plates 42 being used in conjunction with each other to provide a mounting carrier for components such as a roller 43;

[0031] A conveyor belt 4, which is located just below the outlet of the feeding device and is arranged obliquely with the left side lower and the right side higher, is movably arranged between two mounting plates 42. The stainless steel fasteners are transported through the conveyor belt 4. Two rollers 43, which are respectively engaged with the left and right walls inside the conveyor belt 4, are symmetrically rotated and connected between the two mounting plates 42. The two rollers 43 are used in conjunction with each other to move the conveyor belt 4. The fixed part of the second driving device connected to the output shaft and one of the rollers 43 is installed on the outward end of one of the mounting plates 42. The corresponding roller 43 is driven to rotate by the second driving device. The second driving device can adopt a second motor 41.

[0032] The U-shaped plate 5 extending from the left side of the conveyor belt 4 is fitted on the upper end of the conveyor belt 4, and the conveyed stainless steel fasteners are straightened by the U-shaped plate 5, and the transverse parts of the two fixing plates 52 with L-shaped cross sections, whose vertical parts are respectively mounted on the upper ends of the two mounting plates 42, are respectively arranged on the front and rear ends of the U-shaped plate 5. The two fixing plates 52 are used in conjunction with each other to lift the U-shaped plate 5, and then two guide plates 51 with a V-shaped structure arranged with a narrow left and a wide right, located on the left side of the feeding equipment and integrated with the U-shaped plate 5 and fitted on the upper end of the conveyor belt 4, are respectively arranged on the right ends of the two straight plate parts of the U-shaped plate 5. The two guide plates 51 are used in conjunction with each other to guide the stainless steel fasteners into the U-shaped plate 5;

[0033] The trapezoidal cylinder 53, which is located at the lower left of the conveyor belt 4 and is arranged narrow at the bottom and wide at the top, is connected to the lower end of the U-shaped plate 5. The stainless steel fasteners output from the conveyor belt 4 are discharged through the trapezoidal cylinder 53. The lower annular plate 64, which is located on the left side of the conveyor belt 4, is rotatably connected to the lower end of the straight cylinder 6. The straight cylinder 6 provides a mounting carrier for the lower annular plate 64 and other components. The upper annular plate 62 is then set on the upper end of the straight cylinder 6. The upper annular plate 62 provides a mounting carrier for the conical cylinder 61. The conical cylinder 61, which is located just below the trapezoidal cylinder 53 and is arranged wide at the top and narrow at the bottom, is connected to the upper end of the upper annular plate 62. The stainless steel fasteners are introduced into the polishing structure formed by a plurality of polishing wheels 67 through the conical cylinder 61.

[0034] A plurality of polishing wheels 67 are equidistantly arranged on the upper end of the lower annular plate 64, and the plurality of polishing wheels 67 are used in conjunction with each other to polish the outer surface of the stainless steel fastener. A second ring gear 672 located on the upper side of the polishing wheel 67 is set on the inner wall of the straight cylinder 6, and a plurality of auxiliary gears 671 meshing with the inner wall of the second ring gear 672 are respectively set on the upper ends of the plurality of polishing wheels 67. The second ring gear 672 and the auxiliary gear 671 are used in conjunction with each other to make the polishing wheel 67 rotate.

[0035] Two support plates 66 with L-shaped cross-sections and vertical parts set at the upper end of the table 2 are respectively installed on the front and rear ends of the straight cylinder 6. The two support plates 66 are used in combination to lift the straight cylinder 6, and the first ring gear 65 is set on the ring end of the lower ring plate 64. The lower ring plate 64 is rotated through the first ring gear 65, and then the rotating gear 71 is engaged with the right end of the first ring gear 65. The first ring gear 65 is rotated through the rotating gear 71, and the fixed part of the first driving device connecting the output shaft and the rotating gear 71 is set on the upper end of the table 2. The rotating gear 71 is driven to rotate through the first driving device. The first driving device can adopt the first motor 7.

[0036] During use, a large number of stainless steel fasteners are first put into the vibration plate 3, and then the vibration plate 3, the first motor 7 and the second motor 41 are started. The vibration plate 3 will convey the stainless steel fasteners one by one to the upper end of the conveyor belt 4. At the same time, the second motor 41 will drive the corresponding roller 43 to rotate, and with the assistance of another roller 43, the conveyor belt 4 will move, and then the stainless steel fasteners on the conveyor belt 4 will move to the left. At this time, the two guide plates 51 will guide the stainless steel fasteners moving to the left into the U-shaped plate 5, and use the U-shaped plate 5 to correct the stainless steel fasteners to a horizontal state, so as to achieve correction processing for the stainless steel fasteners to be loaded, effectively reducing the probability of the stainless steel fasteners being tilted due to the mechanical loading method, so that the stainless steel fasteners can effectively enter the subsequent polishing process, effectively ensuring the polishing effect and efficiency;

[0037] Then the stainless steel fastener in the horizontal state will enter the trapezoidal cylinder 53 and be converted into a vertical state. Then the stainless steel fastener in the vertical state will enter the polishing structure formed by the multiple polishing wheels 67 along the tapered cylinder 61 and the upper annular plate 62. At the same time, the first motor 7 will drive the rotating gear 71 to rotate. Since the rotating gear 71 and the first ring gear 65 are meshed with each other, the rotation of the rotating gear 71 will cause the first ring gear 65 to rotate, and then the lower annular plate 64 will rotate, thereby causing the multiple polishing wheels 67 to rotate.

[0038] The rotation of the polishing wheel 67 will cause the auxiliary gear 671 to rotate along the inner wall of the second ring gear 672. Since the second ring gear 672 and the auxiliary gear 671 are meshed with each other, the auxiliary gear 671 rotates along the inner wall of the second ring gear 672 and rotates on its own at the same time, thereby causing multiple polishing wheels 67 to rotate on their own. The outer surface of the incoming stainless steel fastener is polished and ground by multiple polishing wheels 67 that rotate in both directions. At the same time, the stainless steel fastener continues to move downward under its own weight and is discharged from the lower annular plate 64, thereby achieving mechanical and orderly polishing of the stainless steel fastener, effectively reducing the probability of slight unevenness on the outer surface of the discharged stainless steel fastener due to factors such as hard burrs, effectively reducing labor intensity and time, and effectively ensuring polishing effect and efficiency.

[0039] Example 2: Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 and Figure 8 As shown, the annular pressure plate 631 is fitted on the lower end of the lower annular plate 64, and the rubber plate 63 is restricted and installed through the annular pressure plate 631, and multiple rods are passed through the annular pressure plate 631 and are slidably connected to the annular pressure plate 631. The rods of the T-shaped rods 633 located on the upper side of the table 2 are equidistantly arranged on the lower end of the lower annular plate 64. The multiple T-shaped rods 633 are used in conjunction with each other to limit the annular pressure plate 631. Then, the elastic member 632 located on the outer side of the rod of the T-shaped rod 633 is arranged between the upper end of the transverse part of the T-shaped rod 633 and the lower end of the annular pressure plate 631. The elastic member 632 applies upward pressure to the annular pressure plate 631, and the elastic member 632 can be a spring.

[0040] A groove is formed on the lower end surface of the lower annular plate 64 to provide installation space for the rubber plate 63. The rubber plate 63 located at the upper end of the annular pressure plate 631 is set in the groove. The stainless steel fasteners entering the straight cylinder 6 are restricted by the rubber plate 63. A cross groove is formed on the lower end surface of the rubber plate 63 to penetrate the rubber plate 63 and is located on the inner side of the lower annular plate 64 and the inner side of the annular pressure plate 631. The stainless steel fasteners pass through the rubber plate 63 through the cross groove. A discharge groove 21 is formed on the upper end surface of the table plate 2 to extend to the left end of the table plate 2 and has a trapezoidal cross section with a wide left and narrow right arrangement and is located directly below the annular pressure plate 631. The polished stainless steel fasteners are discharged through the discharge groove 21.

[0041] After the vertical stainless steel fastener enters the polishing structure formed by the multiple polishing wheels 67, the lower end of the stainless steel fastener contacts the upper end of the rubber plate 63, and the rubber plate 63 confines the stainless steel fastener in the polishing structure. The first motor 7, the rotating gear 71, the first ring gear 65, the lower ring plate 64, the auxiliary gear 671 and the second ring gear 672 are used to make the multiple polishing wheels 67 rotate, thereby polishing the outer surface of the stainless steel fastener.

[0042] When the subsequent vertical stainless steel fastener enters the polishing structure again, the two stainless steel fasteners will fit together. At this time, the upper stainless steel fastener exerts downward pressure on the lower stainless steel fastener under the action of its own weight, and the vertical stainless steel fasteners continue to be transported into the polishing structure. Then, under the downward pressure and the action of the cross groove, the bottom stainless steel fastener causes the cross groove position in the rubber plate 63 to deform, so that the polished stainless steel fastener passes through the rubber plate 63 and falls into the discharge trough 21. Then, the polished stainless steel fastener will be discharged along the discharge trough 21.

[0043] After discharge, the rubber plate 63 returns to its original state and again limits the stainless steel fastener in the polishing structure, so that the rubber plate 63 can limit the stainless steel fastener in the polishing structure formed by the multiple polishing wheels 67, and the stainless steel fastener can be effectively discharged, effectively reducing the probability of incomplete polishing of the stainless steel fastener due to factors such as discharge, and effectively ensuring the polishing effect and efficiency;

[0044] In addition, the annular pressure plate 631 can be pulled downward to compress the multiple elastic members 632, so that the multiple elastic members 632 generate elastic force, and at the same time the annular pressure plate 631 is separated from the rubber plate 63, thereby releasing the restriction on the rubber plate 63, and then the rubber plate 63 is taken out of the groove, and the new rubber plate 63 is put back into the groove, and then the annular pressure plate 631 is loosened, and under the elastic force of the multiple elastic members 632, the annular pressure plate 631 is moved up and re-fitted with the lower end of the lower annular plate 64, and the rubber plate 63 is restricted and installed in the groove again, so that the rubber plate 63 can be easily disassembled and assembled, effectively reducing the probability of incomplete polishing of the polished stainless steel fasteners due to factors such as loss, and effectively ensuring the polishing effect and efficiency.

[0045] Although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
