Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a grinding and dust prevention device for processing hot work die steel bars. Background Technology

[0002] Hot work die steel bars refer to alloy tool steel bars suitable for making dies for hot deformation processing of metals. Hot work die steel bars are widely used in the manufacture of various hot deformation processing dies, such as those in the automotive, aerospace, and machinery manufacturing industries. The chemical composition of hot work die steel bars typically includes alloying elements such as carbon, chromium, manganese, silicon, nickel, tungsten, molybdenum, and vanadium.

[0003] The grinding process at both ends of the bar stock generates metal dust, especially dust containing heavy metals. If inhaled, this dust can damage mucous membranes, leading to a series of health problems such as headaches, dizziness, and decreased vision. Furthermore, if the grinding dust is not removed in time, it will permeate the work area, causing environmental pollution and affecting the visibility and work efficiency of the workers. Therefore, a grinding dust prevention device for hot work die steel bar stock processing is proposed to solve the above-mentioned problems. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] In the embodiments, by Figure 1-5A dust-proof grinding device for processing hot work die steel bars is provided, comprising a processing table 1, and a housing 2 with an opening on one side of the processing table 1. A door panel 3 is hinged to the top of the housing 2 at the opening. A partition 4 is provided inside the housing 2, and the surface of the partition 4 has a material-passing hole 5 for the rod to pass through. The processing table 1 is provided with a conveying component 6 on one side of the partition 4, which is used to control the uniform axial movement of the rod. On the other side of the partition 4, there are grinding devices 7 on the left and right sides of the processing table 1, which are used to grind the end of the rod. A dust-collecting component 8 is provided on the processing table 1 to collect metal dust inside the housing 2. The partition 4 divides the internal space of the housing 2 into a conveying area and a processing area, and the grinding device 7 is located in the processing area. The housing 2 and the door panel 3 form a closed grinding environment, which effectively isolates the metal dust generated during the grinding process. The rod passes through the material-passing hole 5 on the partition 4 at a uniform speed under the drive of the conveying component 6, and the end of the rod is ground by the grinding device 7. The metal dust generated during the grinding process is concentrated inside the housing 2, and then the dust-collecting component 8 collects the metal dust inside the housing 2, keeping the working environment clean and safe.

[0021] Reference Figure 1-5 The conveying assembly 6 includes a fixed base 61 mounted on the processing table 1. A servo motor 62 is fixedly mounted on the fixed base 61. The output end of the servo motor 62 is provided with a drive gear 63 rotatably connected to the fixed base 61. A driven gear 64 meshing with the drive gear 63 is rotatably connected to the fixed base 61. A hinge base 65 is fixedly mounted on the fixed base 61. A movable arm 66 is hinged to the hinge base 65. A first rotating shaft 67 with one end penetrating through and extending to the hinge base 65 is fixedly connected to one side surface of the drive gear 63. A second rotating shaft 68 is connected to one side surface of the driven gear 64 through a coupling. The end of the second rotating shaft 68 away from the coupling passes through the movable arm 66. A limit wheel 69 is provided at one end of both the first rotating shaft 67 and the second rotating shaft 68, and the bar is located between the two limit wheels 69.

[0022] With the above-described structure, the servo motor 62 serves as the power source, driving the drive gear 63 to rotate, and the driven gear 64 will also rotate accordingly. When the drive gear 63 and the driven gear 64 rotate, they will respectively drive the first rotating shaft 67 and the second rotating shaft 68 to rotate. Therefore, the two limit wheels 69 will push the bar to move axially. Furthermore, a connecting piece is provided between the movable arm 66 and the hinge seat 65, which is used to control the rotation range of the movable arm 66 to accommodate bars of different diameters.

[0023] Reference Figure 1-5The movable arm 66 is provided with a brake component 9, which includes a connecting arm 91 rotatably connected to the movable arm 66. A drive motor 92 is fixedly installed on the connecting arm 91, and a brake wheel 93 is provided at the output end of the drive motor 92.

[0024] With the above-mentioned structural configuration, the drive motor 92 controls the rotation of the brake wheel 93, and during the feeding process, the brake wheel 93 will always be in contact with the surface of the bar under the action of gravity. When sufficient friction is generated between the brake wheel 93 and the bar, the bar can be braked to prevent it from continuing to move.

[0025] Reference Figure 1-5 The processing table 1 has multiple columns 10 that are equidistantly distributed on its surface, and the columns 10 are equipped with arc-shaped support plates 11.

[0026] With the above-mentioned structural design, the combination of multiple columns 10 and arc-shaped support plates 11 can ensure sufficient stability during the bar feeding process.

[0027] Reference Figure 1-5 The grinding device 7 includes a mounting base 71 set on the processing table 1, a stepper motor 72 fixedly mounted on the mounting base 71, and a grinding disc 73 set at the output end of the stepper motor 72.

[0028] Reference Figure 1-5 The dust collection component 8 includes an air pump 81 located on one side of the processing table 1. An air pipe 82 is connected between the suction end of the air pump 81 and the housing 2. The discharge end of the air pump 81 is connected to a dust collection box 83 with openings at both the top and bottom. A filter screen 84 located at the bottom opening is provided inside the dust collection box 83.

[0029] With the above-mentioned structure, after the air pump 81 is started, it generates negative pressure through its suction end, which draws in the metal dust in the housing 2 through the air pipe 82. The drawn-in air (containing metal dust) enters the dust collection box 83. The top of the dust collection box 83 is provided with a cover plate. When the dust-containing air enters the dust collection box 83, the dust particles are intercepted by the filter screen 84 and remain in the dust collection box 83, while the clean air flows out of the dust collection box 83 through the filter screen 84, thus achieving the separation of dust and air.
