Description

Technical Field

[0001] The utility model specifically relates to the technical field of automobile parts, and particularly relates to a chrome-plated vertical lifting device for automobile parts. Background Technique

[0002] The chrome-plated layer has a very high hardness. Depending on the composition of the plating solution and process conditions, its hardness can vary within a large range of 400 - 1200 HV. The chrome-plated layer has good heat resistance. When heated below 500 °C, its gloss and hardness do not change significantly. When the temperature is greater than 500 °C, it begins to oxidize and change color, and when the temperature is greater than 700 °C, the hardness begins to decrease. The friction coefficient of the chrome-plated layer is small, especially the dry friction coefficient, which is the lowest among all metals. Therefore, after the automobile parts are chrome-plated, they have very good wear resistance.

In the subsequent process, the workpiece needs to be placed in multiple cavities one by one to ensure the quality of chrome-plating of automobile parts; for this reason, we provide a chrome-plated vertical lifting device for automobile parts. The annular conveyor drives the sliding seat to move, thereby driving the longitudinal guide rail frame to move.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1-5 In an embodiment of the utility model, a vertical lifting device for chrome plating of automotive parts includes an annular conveyor 1; a plurality of sliding seats 2 of the annular conveyor 1 are fixed with longitudinal guide rail frames 3 by bolts, a bearing slide 4 is slidably connected to the longitudinal guide rail frame 3, and a lifting pulley 12 is matched with the seat bearing of the bearing slide 4; the lifting pulley 12 is slidably connected to the inner side of the lifting guide rail frame 11, and the guide ring 10 of the lifting guide rail frame 11 is slidably connected to the guide rod 9; a chrome plating pool 8 is provided under the annular conveyor 1.

[0025] By adopting the above technical solution, the ring conveyor 1 can drive a plurality of sliding seats 2 to move, thereby driving the longitudinal guide frames 3 connected thereto to move. The load-carrying sliding seats 4 on the longitudinal guide frames 3 can move up and down, so that the carried workpieces can be immersed in the chromium plating bath 8 below. The lifting guide frame 11 can pull the lifting pulley 12 to move, so that a plurality of load-carrying sliding seats 4 can move downward simultaneously. Since the lifting pulley 12 is slidably connected to the lifting guide frame 11, it does not affect the movement of the sliding seat 2 along the ring conveyor 1, so that a plurality of workpieces can be immersed in the plurality of cavities of the chromium plating bath 8 one by one.

[0026] In this embodiment, a guide pulley 6 is fitted and connected to the pedestal bearing at the bottom of the longitudinal guide frame 3. The guide pulley 6 is slidably connected to the inner side of the slide rail frame 7, and the slide rail frame 7 is fixed to the chromium plating bath 8 by bolts.

[0027] Furthermore, a fitting carrier frame 5 is connected to the load-carrying sliding seat 4 by bolts.

[0028] By adopting the above technical solution, the guide pulley 6 plays a role in bearing the bottom of the longitudinal guide frame 3. Secondly, it can also prevent the longitudinal guide frame 3 from shaking. The fitting carrier frame 5 on the load-carrying sliding seat 4 facilitates the hanging and placement of automotive parts.

[0029] In this embodiment, the push rod of a lifting cylinder 13 is fitted and connected to the bottom of the lifting guide frame 11. The lifting cylinder 13 is fixed to the ground by bolts.

[0030] Furthermore, the top of the guide rod 9 is fixed to the ring conveyor 1 by bolts, and the guide rod 9 is fixed to the ground by bolts.

[0031] By adopting the above technical solution, the push rod of the lifting cylinder 13 provides power for the movement of the lifting guide frame 11. The guide rod 9 provides a guiding function for the movement of the lifting guide frame 11, and the guide rod 9 also plays a supporting role for the ring conveyor 1.

[0032] In this embodiment, a plurality of cavities are provided inside the chromium plating bath 8. The plurality of cavities are, in sequence along the slide rail frame 7, a degreasing tank, a roughening tank, a sensitizing tank, a peptizing tank, a water washing tank, a chromium plating tank, and a recovery tank.

[0033] By adopting the above technical solution, the degreasing tank inside the chromium plating tank 8 is used to remove grease and other impurities on the surface of the workpiece, ensuring that the subsequent chromium plating layer can adhere well. The main components in the roughening tank are sulfuric acid and chromic acid, which corrode fine holes on the surface of the workpiece to facilitate the adhesion of subsequent processes. The components in the sensitizing tank mainly include palladium acid, stannous chloride, and hydrochloric acid, which can make the surface of the workpiece adsorb palladium ions, reducing the occurrence of overplating and missing plating. The main component inside the peptizing tank is sulfuric acid, and its main function is to remove some substances from the previous process, further reducing the phenomenon of overplating and missing plating. There are degreasing water, hard water, pure water, etc. in the water washing tank, and its function is to clean the surface of the workpiece to avoid residual bath solution affecting the chromium plating quality and appearance. When chromium plating in the chromium plating tank, a relatively high current density is adopted, and current is applied through the anode and cathode to reduce and deposit chromium ions in the plating solution such as chromic anhydride on the surface of the workpiece to form a chromium plating layer. The recovery tank is used to recover the plating solution carried out from the surface of the workpiece, which can be recycled back to the plating tank to supplement the loss due to evaporation, so as to improve the utilization rate of the plating solution, reduce costs, and reduce environmental pollution.

[0034] The working principle of the present utility model is as follows: During use, the annular conveyor 1 can drive multiple sliding seats 2 to move, thereby driving the longitudinally guided frames 3 connected thereto to move. The load-carrying sliding seats 4 on the longitudinally guided frames 3 can move up and down, so that the carried workpieces are immersed in the chromium plating bath 8 below. The lifting guide frame 11 can pull the lifting pulley 12 to move, so that multiple load-carrying sliding seats 4 can move downward simultaneously. Since the lifting pulley 12 is slidably connected to the lifting guide frame 11, it does not affect the movement of the sliding seat 2 along the annular conveyor 1, so that multiple workpieces are successively immersed in multiple cavities of the chromium plating bath 8; the guiding pulley 6 plays a role in supporting the bottom of the longitudinally guided frame 3. Secondly, it can also prevent the longitudinally guided frame 3 from shaking. The accessory carrier 5 on the load-carrying sliding seat 4 facilitates the hanging and placement of automotive accessories; the push rod of the lifting cylinder 13 provides power for the movement of the lifting guide frame 11, and the guiding rod 9 provides a guiding function for the movement of the lifting guide frame 11, and the guiding rod 9 also plays a supporting role for the annular conveyor 1; the degreasing tank inside the chromium plating bath 8 is used to remove grease and other impurities on the surface of the workpiece to ensure that the subsequent chromium plating layer can adhere well. The main components in the roughening tank are sulfuric acid and chromic acid, which corrode fine pores on the surface of the workpiece to facilitate the adhesion of subsequent processes. The main components in the sensitizing tank are palladium acid, stannous chloride, and hydrochloric acid, which can make the surface of the workpiece adsorb palladium ions to reduce the occurrence of overplating and missing plating. The main component inside the peptizing tank is sulfuric acid, and its main function is to remove some substances in the previous process to further reduce the phenomenon of overplating and missing plating. The water washing tank contains degreasing water, hard water, pure water, etc., and its function is to clean the surface of the workpiece to avoid residual bath solution affecting the chromium plating quality and appearance. When chromium plating in the chromium plating bath, a relatively high current density is used. By applying current between the anode and the cathode, chromium ions in the plating solution such as chromic anhydride are reduced and deposited on the surface of the workpiece to form a chromium plating layer. The recovery tank is used to recover the plating solution carried out from the surface of the workpiece, which can be recycled back to the plating tank to supplement the evaporated loss, so as to improve the utilization rate of the plating solution, reduce costs, and reduce environmental pollution.
