Description

Technical Field

[0001] The utility model relates to the field of metal pickling, in particular to a pickling device for metal furniture production. Background Art

[0002] Metal furniture requires the use of some metal sheets during production. After the metal sheets are produced, some oxide films will be produced on the surface. Before processing, these metal sheets need to be pickled to remove the oxide films. During the pickling process, it is generally necessary to use a clamp to clamp the workpiece and then insert it into the pickling liquid. This will prevent the part of the workpiece clamped by the clamp from contacting the pickling liquid, resulting in incomplete pickling of the workpiece. During pickling, the surface of the workpiece will react and produce precipitation, which affects the oxide film on the surface of the workpiece to continue to react with the pickling liquid, resulting in incomplete pickling of the workpiece. Utility Model Content

[0003] In order to overcome the shortcomings that the part of the workpiece clamped by the clamp cannot contact the pickling liquid, and the surface of the workpiece will react and produce precipitation, thereby resulting in incomplete pickling of the workpiece, the utility model provides a pickling device for metal furniture production, which can allow the clamped part of the workpiece to contact the pickling liquid and can scrape off the precipitation generated on the surface of the workpiece during pickling.

[0004] A pickling device for metal furniture production comprises a cleaning tank, the cleaning tank is provided with a protrusion, one side of the cleaning tank is provided with an electric guide rail, the electric guide rail is slidably connected with an electric slider, the upper part of the electric slider is fixedly connected with a guide column, the outer wall of the cleaning tank on the side close to the electric guide rail is provided with a limit frame, the limit frame is provided with a limit groove, the guide column is slidably connected with a sliding frame, the sliding frame is slidably connected to the limit groove on the limit frame, the sliding frame is fixedly connected with a magnetic clamp on the side of the sliding frame away from the guide column, the lower part of the magnetic clamp is provided with a placement opening, a workpiece is placed in the placement opening of the magnetic clamp, the magnetic clamp is installed with a pushing component for pushing the workpiece so that the clamped part of the workpiece can also be pickled, and a scraping component for cleaning the precipitate generated on the surface of the workpiece during the pickling process.

[0005] Further description, the pushing assembly includes a mounting ring, and one mounting ring is fixedly connected to the left and right sides of the magnetic clamp. Each mounting ring is rotatably connected to a friction wheel, one of the friction wheels is in contact with the upper surface of the workpiece, and a threaded frame is connected between the two friction wheels through threads.

[0006] It is further explained that the pushing component also includes rollers, and the bottom surface of the placement opening at the lower part of the magnetic clamp is rotatably connected to two rollers for reducing friction between the workpiece and the magnetic clamp.

[0007] Further description, the scraping assembly includes a scraper, and two of the scrapers are slidably connected to the lower part of the magnetic clamp perpendicular to both sides of the workpiece, and the four scrapers are in contact with the surface of the workpiece. Two return springs are provided between the four scrapers and the magnetic clamp.

[0008] It is further specified that the friction wheel is made of rubber.

[0009] The beneficial effects of the utility model are as follows: 1. When the sliding frame moves to the side away from the protrusion on the cleaning tank, one side of the threaded frame will contact the inner wall of the cleaning tank and will no longer move forward. The sliding frame will continue to move forward to drive the friction wheel to move forward. Under the action of the thread, the two friction wheels will rotate in one direction. The rotation of the friction wheel will push the workpiece to move to the side away from the limit frame. The movement of the workpiece will allow the clamped part to contact the pickling liquid, avoiding incomplete pickling due to the clamped part not contacting the pickling liquid, thereby achieving a more sufficient pickling effect.

[0010] 2. When the friction wheel rotates and pushes the workpiece to move, the scraper will scrape off the sediment on the surface of the workpiece, so that the workpiece will not be pickled incompletely because the surface is covered by the sediment and cannot continue to contact the pickling liquid. The reset spring can keep the scraper close to the surface of the workpiece at all times, ensuring a better and more uniform scraping effect, so that the workpiece can be pickled more thoroughly.

DETAILED DESCRIPTION

[0017] The present invention will now be described more fully below with reference to the accompanying drawings, in which the present invention is shown in its currently preferred embodiments. However, the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0018] Embodiment 1: A pickling device for metal furniture production, such as Figure 1-Figure 5 As shown, it includes a cleaning pool 1, the cleaning pool 1 is provided with a protrusion, an electric guide rail 2 is provided on one side of the cleaning pool 1, an electric slider 3 is slidably connected to the electric guide rail 2, and a guide column 4 is connected to the upper part of the electric slider 3 by bolts, a limiting frame 5 is welded on the outer wall of the cleaning pool 1 close to the electric guide rail 2, a limiting groove is opened on the limiting frame 5, a sliding frame 6 is slidably connected to the guide column 4, the sliding frame 6 is slidably connected to the limiting groove on the limiting frame 5, a magnetic clamp 7 is fixedly connected to the side of the sliding frame 6 away from the guide column 4, a placement opening is opened at the lower part of the magnetic clamp 7, a workpiece 8 is placed in the placement opening of the magnetic clamp 7, a pushing component for pushing the workpiece 8 so that the clamped part of the workpiece 8 can also be pickled, and a scraping component for cleaning the precipitate generated on the surface of the workpiece 8 during the pickling process.

[0019] The pushing assembly includes a mounting ring 9, and a mounting ring 9 is welded on each of the left and right sides of the magnetic clamp 7. A friction wheel 1 is rotatably connected to each mounting ring 9, one of the friction wheels 1 is in contact with the upper surface of the workpiece 8, and a threaded frame 11 is connected between the two friction wheels 1 through threads.

[0020] Initially, the staff places the workpiece 8 into the placement port of the magnetic clamp 7, and then the staff starts the electric slider 3 to move forward. The forward movement of the electric slider 3 drives the guide column 4 to move forward, and the guide column 4 drives the sliding frame 6 to move forward. The forward movement of the sliding frame 6 drives the magnetic clamp 7 and the workpiece 8 to move forward. Under the action of the limit frame 5, the sliding frame 6 will drive the magnetic clamp 7 and the workpiece 8 to move downward into the cleaning tank 1 for pickling. After the workpiece 8 moves downward into the cleaning tank 1 for pickling for a period of time, the staff adjusts the electric slider 3 to move in the opposite direction and reset. The reverse movement and reset of the electric slider 3 will drive the sliding frame 6 to reset, and the reset of the sliding frame 6 will drive the magnetic clamp 7 and the workpiece 8 to reset.

[0021] When the magnetic clamp 7 is brought into the cleaning tank 1 for pickling, the mounting ring 9, the friction wheel 1 and the threaded rack 11 are also driven into the cleaning tank 1. When the sliding rack 6 moves to the side away from the protrusion on the cleaning tank 1, one side of the threaded rack 11 will contact the inner wall of the cleaning tank 1 and no longer move forward. The sliding rack 6 continues to move forward and drives the friction wheel 1 to move forward. Under the action of the thread, both will rotate in one direction. The rotation of the friction wheel 1 will push the workpiece 8 to move to the side away from the limit frame 5. The movement of the workpiece 8 will allow the clamped part to contact the pickling liquid, thereby achieving a more sufficient pickling effect. When the magnetic clamp 7 is reset, the mounting ring 9, the friction wheel 1 and the threaded rack 11 are also driven to reset. When the mounting ring 9, the friction wheel 1 and the threaded rack 11 move to the side close to the protrusion on the cleaning tank 1, the other side of the threaded rack 11 will contact the side wall of the protrusion on the cleaning tank 1 and reset. The reset of the threaded rack 11 will drive the two friction wheels 1 to rotate in the opposite direction to reset, and the reverse rotation of the two friction wheels 1 will drive the workpiece 8 to reset.

[0022] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 3-Figure 5 As shown, the pushing assembly also includes a roller 111, and the bottom surface of the placement opening at the lower part of the magnetic clamp 7 is rotatably connected to two rollers 111 for reducing the friction between the workpiece 8 and the magnetic clamp 7.

[0023] The scraping assembly includes a scraper 12. Two scrapers 12 are slidably connected to the two sides of the lower part of the magnetic clamp 7 perpendicular to the workpiece 8. The four scrapers 12 are in contact with the surface of the workpiece 8. Two return springs 13 are provided between the four scrapers 12 and the magnetic clamp 7.

[0024] The friction wheel 10 is made of rubber, and a relatively rough pattern is engraved on the surface of the friction wheel 10 .

[0025] When the friction wheel 1 rotates to push the workpiece 8 to move, the roller 111 can reduce the friction between the workpiece 8 and the magnetic clamp 7, allowing the workpiece 8 to be pushed more smoothly, while also reducing the probability of wear of the workpiece 8 and the magnetic clamp 7.

[0026] When the friction wheel 1 rotates and pushes the workpiece 8 to move, the scraper 12 will scrape off the precipitates on the surface of the workpiece 8, so that the workpiece will not be pickled incompletely because the surface is covered by the precipitates and cannot continue to contact the pickling liquid. The reset spring 13 can keep the scraper 12 in close contact with the surface of the workpiece 8 at all times, ensuring a better and more uniform scraping effect, allowing the workpiece 8 to be pickled more thoroughly.

[0027] When the friction wheel 10 pushes the workpiece 8 , it can provide greater friction, so that the workpiece 8 can be pushed more smoothly.

[0028] Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the disclosed exemplary embodiments. The scope of the following claims is to be accorded the broadest interpretation so as to encompass all modifications and equivalent structures and functions.
