Abstract
Description
Technical Field
[0001] This utility model relates to the field of hardware processing technology, and in particular to a rust removal device for hardware processing. Background Technology
[0002] Due to prolonged storage, rust will form on the surface of raw metal materials, requiring rust removal before processing. Most current rust removal devices can only remove rust from smooth and regular surfaces. For those with uneven surfaces, manual grinding is required, which is inefficient. Furthermore, current rust removal devices still require secondary processing for internal rust removal of metal parts, using chemical reagents for corrosion. This process is cumbersome and can damage precision parts such as threaded holes.
[0003] To address the aforementioned issues, existing patent (CN212122861U) discloses a rust removal device for hardware processing, specifically relating to the hardware processing field. The device includes a base with a left and right frame mounted at both ends of the base surface. Vertical plates are mounted on the inner sides of the left and right frames, and a rust removal roller is rotatably mounted on the inner side of each vertical plate. Left and right shock-absorbing supports are respectively mounted on the top surfaces of the left and right frames. A disc spring is mounted on the top surface of the right frame, and a motor is connected to the top surface of the disc spring. The inner side of the rust removal roller is filled with abrasive sand, and a baffle is installed on the inner wall of the rust removal roller. This invention removes rust from the surface of hardware by repeatedly rubbing the abrasive sand against the hardware parts. The rust removal roller achieves repeated friction between the abrasive sand and the hardware surface, enabling grinding and rust removal of both the surface and inner wall of the hardware parts. Compared to manual rust removal, it effectively removes rust from narrow areas on the surface of hardware parts, resulting in higher work efficiency and reduced labor intensity.
[0004] However, in the aforementioned prior art, due to the high position of the side cover, it is difficult to remove the hardware and abrasive from the equipment, resulting in low continuous operation efficiency of the rust removal equipment. Utility Model Content

[0023] This utility model provides a rust removal device for hardware processing, including a support base 101 and a rust removal mechanism. The rust removal mechanism includes an extension plate 102, a rust removal box 103, and a discharge assembly. The discharge assembly includes a stirring component, a push plate 111, a connecting sleeve 112, a push rod 113, a limiting rod 114, a collecting component, a discharge plate 115, and a hand-tightening bolt 116. The stirring component includes a hinge 104, an opening and closing plate 105, an input hopper 106, an observation window 107, a motor 108, a drive shaft 109, and a stirring blade 110. The collecting component includes a collecting box 117, a screening frame 118, and a filter screen 119. The aforementioned solution solves the problem that the hardware and grinding sand are difficult to remove from the equipment due to the high position of the side cover, resulting in low continuous operation efficiency of the rust removal equipment.
[0024] In this specific embodiment, the rust removal mechanism includes an extension plate 102, a rust removal box 103, and a discharge assembly. The extension plate 102 is fixedly connected to the support base 101 and is located outside the support base 101. The rust removal box 103 is fixedly connected to the support base 101 and is located above the support base 101. The discharge assembly includes a stirring component, a pushing plate 111, a connecting sleeve 112, a pushing rod 113, a limiting rod 114, and a collecting component. The stirring component is fixedly connected to the rust removal box 103 and is located inside the rust removal box 103. The pushing plate 102... 11 is slidably connected to the rust removal box 103 and located outside the stirring component; the connecting sleeve 112 is fixedly connected to the push plate 111 and located outside the push plate 111, and the connecting sleeve 112 passes through the rust removal box 103; the push rod 113 is rotatably connected to the connecting sleeve 112 and located outside the connecting sleeve 112; the limiting rod 114 is slidably connected to the connecting sleeve 112 and located outside the push rod 113; the collecting component is detachably connected to the extension plate 102 and located above the extension plate 102. The rust removal box 103 is fixed above the support base 101. Hardware parts and abrasive are put into the rust removal box 103. The stirring component stirs the hardware parts and abrasive, achieving grinding and rust removal on the surface and inner wall of the hardware parts. When the hardware parts and abrasive are discharged, the push rod 113 is rotated. The push rod 113 drives the limiting rod 114 to rotate within the connecting sleeve 112, so that the limiting rod 114 releases its restriction on the push rod 113. The push rod 113 pushes inward into the rust removal box 103, and the connecting sleeve 112 pushes the push rod 113 inward. The push plate 111 moves, and the push plate 111 pushes out the hardware and abrasive in the rust removal box 103. After the hardware and abrasive are completely pushed out, the push rod 113 drives the push plate 111 to reset. After the reset is completed, the push rod 113 is rotated so that the limiting rod 114 fits against the rust removal box 103, thereby fixing the push plate 111. When the push plate 111 is fixed, it is hidden inside the rust removal box 103. This method can effectively solve the problem that the hardware and abrasive are difficult to be exported from the equipment, resulting in low continuous operation efficiency of the rust removal equipment.
[0025] The stirring component includes a hinge 104 and a hinge plate 105. The hinge 104 has a lower page and an upper page. The lower page of the hinge 104 is fixedly connected to the rust removal box 103. The hinge plate 105 is fixedly connected to the upper page of the hinge 104 and is located above the rust removal box 103. The hinge plate 105 opens and closes above the rust removal box 103 via the hinge 104.
[0026] Secondly, the stirring component also includes an input hopper 106 and an observation window 107. The input hopper 106 is fixedly connected to the rust removal box 103 and is located below the opening and closing plate 105. The observation window 107 is fixedly connected to the rust removal box 103 and extends through the rust removal box 103. Hardware parts and grinding sand are input into the rust removal box 103 through the input hopper 106. The observation window 107 facilitates observation of the condition inside the rust removal box 103.
[0027] Meanwhile, the stirring component also includes a motor 108, a drive shaft 109, and a stirring blade 110. The motor 108 is fixedly connected to one end of the drive shaft 109 and is located outside the rust removal box 103. The other end of the drive shaft 109 is rotatably connected to the rust removal box 103 and is located below the feeding hopper 106. The stirring blade 110 is fixedly connected to the drive shaft 109 and is located on the side of the push plate 111 away from the connecting sleeve 112. The motor 108 drives the drive shaft 109 to rotate, and the drive shaft 109 drives the stirring blade 110 to rotate. The stirring blade 110 drives the hardware parts and the grinding sand to rotate. The repeated friction between the grinding sand and the hardware parts removes the rust stains on the surface of the hardware parts.
[0028] In addition, the stirring blade 110 has a plurality of through grooves 120, which reduce the resistance of the stirring blade 110 in pushing the grinding sand.
[0029] Secondly, the unloading assembly also includes an unloading plate 115 and a hand-tightening bolt 116. The unloading plate 115 is rotatably connected to the rust removal box 103 and is located on the side of the stirring blade 110 away from the push plate 111. The hand-tightening bolt 116 is threadedly connected to the rust removal box 103 and is located on the outside of the unloading plate 115. The hand-tightening bolt 116 passes through the unloading plate 115. When unloading hardware parts and grinding sand, the hand-tightening bolt 116 is manually unscrewed. When the push plate 111 pushes the hardware parts and grinding sand, the hardware parts and grinding sand will push the unloading plate 115 to rotate around the rust removal box 103, so that the discharge port opens and pushes the hardware parts and grinding sand out of the rust removal box 103.
[0030] Meanwhile, the collecting component includes a collecting box 117, which is detachably connected to the extension plate 102 and located above the extension plate 102. The collecting box 117 is placed above the extension plate 102 and is used to push out hardware parts and grinding sand.
[0031] In addition, the collection device also includes a screening frame 118 and a filter screen 119. The screening frame 118 is detachably connected to the collection box 117 and is located inside the collection box 117. The filter screen 119 is fixedly connected to the screening frame 118 and is located inside the screening frame 118. The filter screen 119 is adapted and replaced according to the size of the grinding sand. The filter screen 119 filters the hardware and the grinding sand, so that the grinding sand falls into the collection box 117, while the hardware is intercepted by the filter screen 119. After screening, the screening frame 118 can be directly separated from the collection box 117, thereby facilitating the quick separation of hardware and grinding sand.
[0032] Using the rust removal equipment for hardware processing according to this embodiment, by setting the extension plate 102, the rust removal box 103, and the unloading assembly, in specific use, the opening and closing plate 105 is opened by the hinge 104, and the hardware and abrasive are put into the rust removal box 103 through the feeding hopper 106. The motor 108 drives the drive shaft 109 to rotate, and the drive shaft 109 drives the stirring blade 110 to rotate. The stirring blade 110 drives the hardware and abrasive to rotate, and the rust stains on the surface of the hardware are removed through repeated friction between the abrasive and the hardware. The observation window 107 can be used to observe the operation process, and through the observation window 107, it can be observed that the stirring blade 110 is horizontally stationary in the rust removal box 103. When unloading the hardware and abrasive, the hand-tightening bolt 116 is manually unscrewed to release the unloading plate 103. With 15 fixed, the push rod 113 is rotated, causing the limiting rod 114 to rotate within the connecting sleeve 112, thus releasing the limiting rod 114 from restricting the push rod 113. The push rod 113 pushes the inside of the rust removal box 103, and the connecting sleeve 112 pushes the push plate 111 to move. The push plate 111 pushes out the hardware and abrasive in the rust removal box 103. The hardware and abrasive push the unloading plate 115 to rotate around the rust removal box 103, causing the hardware and abrasive to fall above the filter screen 119. The filter screen 119 filters the hardware and abrasive, causing the abrasive to fall into the collection box 117, while the hardware is intercepted by the filter screen 119. This allows for convenient removal of the hardware and abrasive from the rust removal equipment, effectively improving the continuous operation efficiency of the rust removal equipment.
[0033] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
