When the push block contacts the steel bar, it squeezes the steel bar into the conveying pipe until the push block moves below the steel bar. The steel bar closest to the rectangular opening then automatically rolls to the baffle, facilitating the conveying of the next set of steel bars.

Description

Technical Field

[0001] This utility model relates to the field of steel processing technology, and in particular to a feeding device for a bright steel bar grinding machine. Background Technology

[0002] Bright silver steel, a high-precision round steel produced through fine processing such as polishing, grinding, and drawing, possesses core characteristics including high dimensional accuracy, excellent surface finish, and absence of rolling defects and decarburization layers. It is widely used in fields with stringent surface quality requirements, such as mechanical parts, bearings, and tools. In its processing, the steel bars, after peeling and heat treatment, need further grinding on a grinding machine to meet the customer's specified diameter tolerances and surface roughness requirements. The feeding device, as a crucial pre-processing step before grinding, directly affects processing accuracy and production efficiency.

[0003] In the early days, silver-bright steel grinding machines generally used a manual feeding method, where operators had to move the steel bars from the material rack to the grinding machine chuck or support mechanism.

[0004] Manual material loading not only increases the workload of workers, but also results in low work efficiency.

[0005] Therefore, it is necessary to provide a feeding device for grinding machines of bright steel bars to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a feeding device for a bright steel bar grinding machine, solving the problem that manual feeding not only increases the workload of workers but also results in low work efficiency. To address the above technical problems, the feeding device for a bright steel bar grinding machine provided by this utility model includes a rectangular base and a feeding assembly. The rectangular base has a rectangular cavity inside, and a sliding groove is formed on the left side of the rectangular base, communicating with the rectangular cavity. A lifting assembly is installed between the sliding groove and the inner wall of the rectangular cavity. The lifting assembly is connected to a material-picking assembly. Several groups of steel bars are arranged inside the feeding assembly. A grinding groove is formed on the top of the rectangular base. Mounting frames are fixedly installed on the side walls of the rectangular base located on the front and rear outer walls of the grinding groove, and clamping assemblies are installed on the mounting frames.

[0007] Preferably, the material conveying assembly includes a conveying pipe, a number of support legs are fixedly installed at the bottom of the conveying pipe, a number of steel bars are evenly arranged inside the conveying pipe, a rectangular opening is provided at the top right end of the conveying pipe, and a baffle is fixedly installed on the side wall of the right end of the conveying pipe.

[0008] Preferably, the lifting assembly includes a motor, which is fixed at the top of the rectangular cavity. A gear is fixedly installed at the output end of the motor. A threaded rod is rotatably connected between the top and bottom of the slide groove. A threaded block is threadedly connected to the outer wall of the threaded rod. The side wall of the threaded block is in close contact with the inner wall of the slide groove. The outer wall of the threaded block is connected to the material picking assembly. A toothed ring is fixedly installed at the lower end of the threaded rod, and the toothed ring meshes with the gear.

[0009] Preferably, the material handling assembly includes a connecting plate, which is fixedly connected to the threaded block side plate. Push plates are fixedly installed on both the front and rear sides of the connecting plate, and a push block is fixedly installed on the side wall of the connecting plate located in the middle of the two sets of push plates.

[0010] Preferably, the push block is a right-angled trapezoid, and the side of the push block closest to the steel bar is an inclined surface.

[0011] Preferably, the clamping assembly includes a cylinder, which is fixed to the side plate of the mounting frame, extends through the mounting frame into the grinding groove, and a clamping plate is fixedly installed at the output end of the cylinder.

[0012] Preferably, a control device is fixedly installed on the side plate of the rectangular seat, and the control device is electrically connected to the motor.

[0013] Compared with related technologies, the feeding device for grinding bright steel bars provided by this utility model has the following advantages:

[0014] When the threaded block drives the connecting plate to move upward, the connecting plate drives the steel bar near the rectangular opening to move upward through the push plate. After the steel bar leaves the conveying pipe, it automatically rolls to the left side of the rectangular seat and sticks to the rectangular seat until the steel bar moves to the top of the rectangular seat. Finally, it rolls into the grinding groove. When picking up materials, the threaded block drives the connecting plate to move downward. When the push block contacts the steel bar, it will squeeze the steel bar to move into the conveying pipe until the push block moves to the bottom of the steel bar. The steel bar closest to the rectangular opening automatically rolls to the baffle to facilitate the conveying of the next set of steel bars.

[0015] The pusher is a right-angled trapezoid with an inclined surface on the side of the pusher closest to the steel bar. The inclined surface increases the contact area with the steel bar, making it easier to squeeze the steel bar. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 A schematic diagram of a preferred embodiment of the feeding device for a silver-bright steel bar grinding machine provided by this utility model; Figure 2 for Figure 1 The diagram shows the internal structure of the chute. Figure 3 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 2 The enlarged schematic diagram of part B is shown. The feeding device for the silver bright steel bar grinding machine includes: a rectangular base 1 and a feeding assembly 7. The rectangular base 1 has a rectangular cavity 11 inside. The rectangular base 1 has a sliding groove 6 on the left side, which communicates with the rectangular cavity 11. A lifting assembly 10 is installed between the sliding groove 6 and the inner wall of the rectangular cavity 11. The lifting assembly 10 is connected to a material picking assembly 9. Several groups of steel bars 8 are arranged inside the feeding assembly 7. A grinding groove 5 is opened on the top of the rectangular base 1. Mounting brackets 4 are fixedly installed on the side walls of the rectangular base 1 located on the front and rear outer walls of the grinding groove 5. Clamping assemblies 3 are installed on the mounting brackets 4.

[0023] The material conveying assembly 7 includes a conveying pipe 72. Several sets of support legs 71 are fixedly installed at the bottom of the conveying pipe 72. Several sets of steel bars 8 are evenly arranged inside the conveying pipe 72. A rectangular opening 73 is opened at the top right end of the conveying pipe 72. A notch is opened in the conveying pipe 72 directly below the rectangular opening 73. The notch is smaller than the rectangular opening 73 and does not affect the movement of the material picking assembly 9. A baffle 74 is fixedly installed on the right side wall of the conveying pipe 72. The baffle 74 is used to prevent the steel bars 8 from slipping.

[0024] The lifting assembly 10 includes a motor 103, which is fixed at the top of the rectangular cavity 11. A gear 104 is fixedly installed at the output end of the motor 103. A threaded rod 101 is rotatably connected between the top and bottom of the slide groove 6. A threaded block 102 is threadedly connected to the outer wall of the threaded rod 101. The side wall of the threaded block 102 is in close contact with the inner wall of the slide groove 6. The outer wall of the threaded block 102 is connected to the material picking assembly 9. A toothed ring 105 is fixedly installed at the lower end of the threaded rod 101. The toothed ring 105 is meshed with the gear 104.

[0025] The output end of the motor 103 drives the gear 104 to rotate, which in turn drives the threaded rod 101 to rotate through the gear ring 105, thereby driving the material taking component 9 to move up and down through the threaded block 102.

[0026] The material handling component 9 includes a connecting plate 91, which is fixedly connected to the side plate of the threaded block 102. Push plates 92 are fixedly installed on both the front and rear sides of the connecting plate 91, and a push block 93 is fixedly installed on the side wall of the connecting plate 91 located in the middle of the two sets of push plates 92.

[0027] When the threaded block 102 drives the connecting plate 91 to move upward, the connecting plate 91 drives the steel rod 8 near the rectangular opening 73 to move upward through the push plate 92. After the steel rod 8 is separated from the conveying pipe 72, it automatically rolls to the left side of the rectangular seat 1 and sticks to the rectangular seat 1 until the steel rod 8 moves to the top of the rectangular seat 1. Finally, it rolls into the grinding groove 5. When the material is picked up again, the threaded block 102 drives the connecting plate 91 to move downward. When the push block 93 contacts the steel rod 8, it will squeeze the steel rod 8 to move into the conveying pipe 72. After the push block 93 moves to the bottom of the steel rod 8, the steel rod 8 closest to the rectangular opening 73 automatically rolls to the baffle 74.

[0028] The pusher block 93 is a right-angled trapezoid, and the side of the pusher block 93 closest to the steel rod 8 is inclined. The inclined surface increases the contact area with the steel rod 8, making it easier to squeeze the steel rod 8.

[0029] The clamping assembly 3 includes a cylinder 31, which is fixed to the side plate of the mounting frame 4. The cylinder 31 passes through the mounting frame 4 and extends into the grinding groove 5. A clamping plate 32 is fixedly installed at the output end of the cylinder 31. When the steel rod 8 rolls into the grinding groove 5, the output end of the cylinder 31 pushes the clamping plate 32 to clamp the front and rear ends of the steel rod 8, which facilitates subsequent grinding.

[0030] A control device 2 is fixedly installed on the side plate of the rectangular base 1. The control device 2 is electrically connected to the motor 103. The control device 2 is a PLC controller used to control the operation of the motor 103.

[0031] The working principle of the feeding device for the silver bright steel bar grinding machine provided by this utility model is as follows:

[0032] The feeding assembly 7 automatically and orderly conveys the steel bars 8 to the picking point. The lifting assembly 10 drives the picking assembly 9 to take the steel bars 8 out from the right end of the feeding assembly 7 and then convey them to the top of the rectangular seat 1. Due to the height difference between the feeding assembly 7 and the top of the rectangular seat 1, when the steel bars 8 reach the top of the rectangular seat 1, they automatically roll into the grinding groove 5 and are then limited by the clamping assembly 3 to facilitate subsequent grinding. When the lifting assembly 10 drives the picking assembly 9 to move downward, the picking assembly 9 will automatically squeeze the steel bars 8 into the feeding assembly 7 to facilitate the picking assembly 9 to come under the steel bars 8 so that the next set of steel bars 8 can be conveyed.

[0033] Compared with related technologies, the feeding device for grinding bright steel bars provided by this utility model has the following advantages:

[0034] When the threaded block 102 drives the connecting plate 91 to move upward, the connecting plate 91 drives the steel rod 8 near the rectangular opening 73 to move upward through the push plate 92. After the steel rod 8 is separated from the conveying pipe 72, it automatically rolls to the left side of the rectangular seat 1 and sticks to the rectangular seat 1 until the steel rod 8 moves to the top of the rectangular seat 1. Finally, it rolls into the grinding groove 5. When the material is picked up again, the threaded block 102 drives the connecting plate 91 to move downward. When the push block 93 contacts the steel rod 8, it will squeeze the steel rod 8 into the conveying pipe 72. After the push block 93 moves to the bottom of the steel rod 8, the steel rod 8 closest to the rectangular opening 73 automatically rolls to the baffle 74 to facilitate the conveying of the next set of steel rods 8.

[0035] The push block 93 is a right-angled trapezoid, and the side of the push block 93 closest to the steel rod 8 is inclined. The inclined surface increases the contact area with the steel rod 8, making it easier to squeeze the steel rod 8.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
