Description

Technical Field

[0002] Hardware refers to tools made of metals such as gold, silver, copper, iron, and tin through processing and casting. They are used to fix things, process things, and decorate. For example, gaskets are painted and then baked during production to improve their oxidation resistance and appearance.

[0003] Chinese utility model patent CN220991621U discloses a metal baking device that facilitates uniform baking. The blower is connected to a hose and a U-shaped sliding tube so that the air outlet blows air towards the heating equipment and the outside of the metal parts. The second motor can make the air outlet reciprocate along the installation direction of the heating equipment, which blows the high-temperature air around the heating equipment into the inner cavity of the baking oven, thereby making the inner cavity of the baking oven heat up quickly and the temperature relatively uniform in all places, thus improving the baking efficiency.

[0004] However, in actual use, since the hardware parts are placed in the baking oven, the bottom surface of the hardware parts is in contact with the support surface, which will cause uneven paint coating on the contact surface, affecting the paint coating effect of the hardware parts and thus affecting the oxidation resistance of the hardware parts.

[0008] The processing box is equipped with a power component and a limiting component on its inner side. The power component is used to drive the support frame to perform lifting and lowering movements, and the limiting component is used to limit the axial movement direction of the support frame.

[0009] In a preferred embodiment of this utility model, a plurality of top posts and a plurality of contact posts on each of the placement plates are staggered, and the plurality of placement plates are evenly distributed on the top of the partition in a linear array.

[0010] In a preferred embodiment of this utility model, the power assembly includes: a fixing block fixed to the bottom of the inner side of the processing box, a connecting frame installed on one side of the fixing block, and a servo motor installed on one side of the connecting frame; a worm gear is installed at the output end of the servo motor, and a worm wheel is rotatably connected to the top of the fixing block;

[0011] A connecting block is fixed to the bottom of the support frame, and a threaded rod is fixed to the bottom of the connecting block. The bottom of the threaded rod is located inside the fixing block and has a limit groove. A limit pin is fixed to the inside of the fixing block, and one end of the limit pin is located inside the limit groove.

[0012] In a preferred embodiment of this utility model, the two ends of the worm are rotatably connected to the inner side of the connecting frame, the side of the threaded rod is threadedly connected to the inner side of the worm wheel, and the diameter of the limiting pin is the same as the width of the limiting groove.

[0015] In a preferred embodiment of this utility model, the processing box is slidably connected to an opening and closing door on the front of the top of the partition, and a sealing ring is provided at the connection between the opening and closing door and the processing box.

[0019] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0020] (1) This utility model provides a hardware processing post-processing device. By setting a contact mechanism inside the processing box, the pad to be painted is placed on the top of the placement plate. Hot air is supplied to the processing box by a hot air blower to achieve the painting post-processing. With the cooperation of the power component, the limiting component, the support frame and the top column, the top column can pass through the top of the placement plate to form a lifting action. It can cooperate with the contact column to form staggered contact with the pad. The hot air generated by the hot air blower is guided by the partition to form a circulation, thereby achieving uniform painting post-processing of the hardware. This avoids uneven painting on the contact surface caused by static placement, which affects the painting effect of the hardware and reduces the oxidation resistance of the hardware.

[0021] (2) In this utility model, by setting up the power component, with the cooperation of servo motor, worm, worm wheel, threaded rod, limit pin and limit groove, the lifting motion can be realized. The sliding of the limit pin in the limit groove ensures vertical guidance and restricts circumferential rotation. The self-locking characteristics of the worm wheel and worm ensure that it is suspended at any position. Thus, the connecting block transmits the power to the support frame to form a stable thrust, thereby realizing the lifting of the top column.

[0022] (3) In this utility model, with the cooperation of the limiting component, when the support frame moves up and down under the drive of the power component, the axial movement direction of the support frame can be limited by the cooperation of the limiting block and the limiting rod, so as to ensure that the support frame can only move in a straight line along the vertical direction, prevent the support frame from deviating or shaking during the movement, and ensure the stability and reliability of the contact mechanism.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a hardware processing post-processing device includes: a processing box 1, a hot air blower 2 installed on the top of the processing box 1 for supplying hot air to the interior of the processing box 1, and a partition 3 fixed inside the processing box 1; the interior of the processing box 1 is provided with a contact mechanism, which includes: a plurality of placement plates 4 fixed on the top of the partition 3, a plurality of contact posts 41 fixed on the top of the placement plates 4, and a support frame 42 provided at the bottom of the partition 3; the support frame 42 is fixed with a plurality of top posts 43 facing the bottom of the plurality of placement plates 4, and the top ends of the plurality of top posts 43 extend through to the top of the plurality of placement plates 4; the interior of the processing box 1 is provided with a power component and a limiting component, the power component is used to drive the support frame 42 to perform lifting and lowering movements, and the limiting component is used to limit the axial movement direction of the support frame 42.

[0031] It should be noted that the top posts 43 and contact posts 41 on each placement plate 4 are staggered, and the placement plates 4 are evenly distributed on the top of the partition plate 3 in a linear array. The air outlet of the hot air blower 2 is located at the top of the processing box 1 and is diffused to provide homogeneous hot air and avoid local overheating. The hot air blower 2 consists of a blower, a heater and a control circuit to regulate the working temperature and air volume. During the drying operation, the blower in the hot air blower 2 blows air into the heater, so that the air passes evenly through the inside and outside of the spiral heating wire. The heat generated by the heating wire after being energized exchanges heat with the passing cold air, so that the air temperature at the air outlet increases, thereby increasing the air temperature and blowing air.

[0032] Specifically, after the pad to be painted is placed on top of the placement plate 4, the contact column 41 will contact its bottom. Hot air is supplied to the processing box 1 by the hot air blower 2 to achieve post-painting treatment. At the same time, through the cooperation of the power component and the limit component, the support frame 42 is driven to move up and down. Under the movement of the support frame 42, the top column 43 can pass through the top of the placement plate 4 to form a lifting action, which can cooperate with the contact column 41 to form staggered contact with the pad. The hot air generated by the hot air blower 2 is guided by the partition 3 to form circulation, thereby achieving uniform post-painting treatment of the hardware parts and avoiding uneven paint on the contact surface caused by static placement, which would affect the paint effect of the hardware parts and reduce the oxidation resistance of the hardware parts.

[0033] like Figure 4 As shown, in some embodiments, the power assembly includes: a fixing block 5 fixed to the bottom of the inner side of the processing box 1, a connecting frame 51 installed on one side of the fixing block 5, and a servo motor 52 installed on one side of the connecting frame 51; a worm gear 53 is installed at the output end of the servo motor 52, and a worm wheel 54 is rotatably connected to the top of the fixing block 5; a connecting block 55 is fixed to the bottom of the support frame 42, and a threaded rod 56 is fixed to the bottom of the connecting block 55, the bottom of the threaded rod 56 is located inside the fixing block 5, and a limit groove 57 is formed therein; a limit pin 58 is fixed to the inner side of the fixing block 5, and one end of the limit pin 58 is located inside the limit groove 57.

[0034] It should be noted that the two ends of the worm 53 are rotatably connected to the inner side of the connecting bracket 51, the side of the threaded rod 56 is threadedly connected to the inner side of the worm wheel 54, and the diameter of the limiting pin 58 is the same as the width of the limiting groove 57.

[0035] Specifically, when the servo motor 52 starts, it can drive the worm gear 53 to rotate. Since the worm gear 53 meshes with the worm wheel 54, the rotation of the worm gear 53 will drive the worm wheel 54 to rotate. The lifting and lowering motion is achieved through the threaded connection between the internal thread of the worm wheel 54 and the threaded rod 56. The sliding of the limit pin 58 in the limit groove 57 ensures both vertical guidance and restricts circumferential rotation. The self-locking characteristics of the worm wheel 54 and worm gear 53 ensure that the worm gear 54 can be suspended at any position. Thus, the connecting block 55 transmits power to the support frame 42 to form a stable thrust, thereby realizing the lifting and lowering of the top column 43.

[0036] like Figure 2 As shown, in some embodiments, the limiting component includes: a plurality of limiting rods 6 fixed to the bottom of the partition 3, and a plurality of limiting blocks 61 sleeved on the side of the limiting rods 6; one side of the limiting block 61 is fixed to the side of the support frame 42.

[0037] It should be noted that the bottom end of the limiting rod 6 is fixed to the inner bottom of the processing box 1, and the number of limiting rods 6 and limiting blocks 61 is the same.

[0038] Specifically, when the support frame 42 moves up and down under the drive of the power component, the limit block 61 will slide up and down along the limit rod 6. The cooperation between the limit rod 6 and the limit block 61 limits the axial movement direction of the support frame 42, ensuring that the support frame 42 can only move in a straight line along the vertical direction (i.e., the axial direction of the limit rod 6), preventing the support frame 42 from deviating or shaking during the movement, and ensuring the stability and reliability of the contact mechanism.

[0039] like Figure 1 As shown, in some embodiments, the front of the processing box 1 located on the top of the partition 3 is slidably connected to an opening and closing door 7, and a sealing ring is provided at the connection between the opening and closing door 7 and the processing box 1; by setting the opening and closing door 7, the front of the processing box 1 can be closed, and the sealing ring can ensure the sealing of the inside of the processing box 1, prevent hot air leakage, improve the efficiency of heat treatment or drying processes, and at the same time ensure the temperature stability inside the processing box 1.

[0040] In some embodiments, a handle 8 is fixed on the front of the opening and closing door 7 for easy operation by the operator; the handle 8 facilitates the operator to pull the opening and closing door 7, thereby enabling the opening and closing of the door 7.

[0041] In some embodiments, the front of the opening and closing door 7 is provided with an observation window 9 for the operator to easily observe the internal condition of the processing box 1; through the observation window 9, the operator can easily observe the processing status of the hardware inside the processing box 1 so as to make timely adjustments.

[0042] In some embodiments, the bottom of the processing box 1 is fixed with several support legs 10 for supporting the surface; the arrangement of several support legs 10 makes the processing box 1 stable on the ground, avoiding the processing box 1 from being in direct contact with the ground and being affected by wear or moisture, and also facilitating the installation and movement of the processing box 1.

[0043] In use, the gasket to be painted is placed on the placement plate 4 arranged in a linear array on top of the partition 3. The contact post 41 contacts the bottom of the gasket. The hot air blower 2 is started, and its blower blows air into the heater. The air passes evenly through the inside and outside of the spiral heating wire, exchanging heat with the heat generated after the heating wire is energized. This causes the air outlet to spray out homogeneous hot air in a diffused manner. The hot air is guided by the partition 3 to form a circulation. At the same time, the servo motor 52 starts and drives the worm gear 53 to rotate. Because the worm gear 53 meshes with the worm wheel 54, the worm wheel 54 rotates accordingly. Because the threaded rod 56 is threadedly connected to the inner side of the worm wheel 54 and is restricted from rotation by the limiting pin 58 and the limiting groove 57, the threaded rod 56 moves along the... The worm gear 54 moves up and down axially, which in turn drives the support frame 42 to move up and down. The limiting block 61 fixed on the side of the support frame 42 slides up and down along the limiting rod 6 fixed at the bottom of the partition plate 3 to ensure that the support frame 42 moves vertically and linearly. When the support frame 42 moves up and down, the top column 43 passes through the top of the placement plate 4 to form a lifting action, and cooperates with the contact column 41 to form staggered contact with the gasket, so that the hot air can be evenly applied to all parts of the gasket, avoiding uneven paint baking on the contact surface caused by static placement. The operator can open or close the opening and closing door 7 through the handle 8 on the front of the opening and closing door 7. The sealing ring ensures the airtightness of the processing box 1, the observation window 9 facilitates observation of the internal processing status, and the support leg 10 at the bottom of the processing box 1 plays a role in stabilizing support.
