Description

Technical Field

[0001] The utility model relates to the technical field of electroplating, in particular to a metal pipe electroplating processing supporting device. Background Art

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to adhere a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhancing aesthetics.

[0003] In the prior art, the Chinese utility model with publication number: CN212426225U discloses a metal tube electroplating processing support device. The technical problem to be solved by the utility model is that some existing metal tube support frames on the market are not convenient for fixing metal tubes of different sizes. In order to solve the above technical problems, the utility model provides a metal tube electroplating processing support device, including a base plate, a main slide groove is arranged on the top of the base plate, and main sliders are movably sleeved at both ends of the inner wall of the main slide groove, support arms are symmetrically welded on the tops of the two main sliders, and a transfer box is fixedly sleeved in the through opening arranged on one side of the support arm, and a transfer plate is fixedly sleeved in the transfer box. During use, the utility model supports the two ends of the metal tube through the push of four reset springs respectively, so that the user can perform electroplating spraying, and because its limitation range can be adjusted by the elasticity of the reset spring, it can adapt to the use of metal tubes of different sizes.

[0004] In the above technical solution, the two sets of racks are located on both sides of the gear and are not in the same straight line, resulting in the extension direction of the rack not being on the diameter path of the metal tube to be electroplated. If the metal tube needs to be supported from the inside by the rack, the rack needs to be extended outward. Since the extension direction of the rack does not coincide with the diameter of the metal tube, it is easy for the rack to bend due to the restriction of the arc of the inner wall of the metal tube when supporting the metal tube through the limit pad. If used for a long time, it is easy to cause the rack to not be able to extend and retract smoothly in the adapter box, resulting in inconvenience in supporting the metal tube. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] like Figures 1 to 3 A metal tube electroplating treatment support device shown in the figure comprises a cylindrical barrel 1, through grooves 2 are provided on the surface of the cylindrical barrel 1 on all sides, a movable block 3 is movably provided in the inner cavity of the cylindrical barrel 1, the outer side of the movable block 3 extends to the inner cavity of the through groove 2, a groove is provided on the outer side of the movable block 3, and the inner cavity of the groove is movably connected to a movable support rod 4 through a movable shaft, and one end of the movable support rod 4 away from the movable block 3 is movably connected to an extrusion plate 5 through a movable seat, and the inner cavity of the cylindrical barrel 1 is provided with a horizontal push component for moving the movable block 3;

[0024] The extrusion plate 5 and the support rod 4 are movably connected through a movable seat. After the extrusion plate 5 fits the inner wall of the metal tube, the angle can be automatically adjusted through the extrusion of the support rod 4, so that the outer side of the extrusion plate 5 is completely fitted on the inner wall of the metal tube, and the stability of the support of the metal tube by the extrusion plate 5 is guaranteed. Since the support rod 4 is arranged in a counter-positioned manner around the cylindrical tube 1 and coincides with the diameter of the metal tube, the stability of the device is guaranteed, and deformation of the device caused by supporting it from the inside of the metal tube is avoided, which is not conducive to the later use of the device.

[0025] The side of the extrusion plate 5 is hinged with a limit link 7 through a hinge. The end of the limit link 7 away from the extrusion plate 5 is hinged to the outer side of one end of the cylindrical tube 1 through a hinge. Through the setting of the limit link 7, the extrusion plate 5 and the support rod 4 can be limited. Through the movement of the movable block 3 and the cooperation of the limit link 7, the extrusion plate 5 is expanded outward, which is convenient for supporting metal tubes of different sizes from the inside.

[0026] The push assembly includes a driving motor 8 fixed to one end of the cylindrical barrel 1. The output shaft of the driving motor 8 passes through the inner cavity of the cylindrical barrel 1 and is fixed with a screw 9 that rotates in the inner cavity of the cylindrical barrel 1 using a bearing. The screw 9 passes through the movable block 3 and is threadedly connected to the movable block 3 through a screw sleeve. The driving motor 8 drives the screw 9 to rotate, and then cooperates with the screw sleeve to drive the movable block 3, so that the movable block 3 can be translated inside the cylindrical barrel 1, which is convenient for adjusting the extrusion plate 5 through the support rod 4 and the limit connecting rod 7.

[0027] A fixed head 10 is fixed at one end of the cylindrical tube 1, and the end of the fixed head 10 away from the cylindrical tube 1 is set in a truncated cone shape. The setting of the fixed head 10 is convenient for limiting the minimum metal pipe size that the device can support and limit. At the same time, one end of the fixed head 10 is set in a truncated cone shape, which is convenient for inserting the device into the metal pipe, moving inside the metal pipe, and supporting and fixing the metal pipe from different positions inside the metal pipe.

[0028] The outer side of the extrusion plate 5 is arranged in an arc shape, and a wear-resistant rubber pad 12 for increasing resistance is bonded to the outer side of the extrusion plate 5. By setting the shape of the extrusion plate 5, it is convenient for the extrusion plate 5 to fit the inner wall of the metal tube, so that the contact surface is increased. At the same time, the rubber pad 12 is used to increase the friction between the extrusion plate 5 and the metal tube, thereby ensuring the stability of the extrusion plate 5 supporting the metal tube and preventing the extrusion plate 5 from sliding inside the metal tube and failing to fix and support the metal tube.

[0029] A cut angle 6 is provided on the side facing the extrusion plate 5 and the limit link 7, and the degree of the cut angle 6 is 45 degrees. Through the setting of the cut angle 6, it is convenient for the limit link 7 to avoid collision between the limit link 7 and the extrusion plate 5 when limiting the support of the extrusion plate 5. The degree of the cut angle 6 is limited to ensure that the extrusion plate 5 is perpendicular to the limit link 7 after moving the farthest distance.

[0033] During specific use, the cylindrical tube 1 is inserted into the metal tube, and then the driving motor 8 or the electric push rod 11 is used to drive the movable block 3 to move inside the cylindrical tube 1. The movable block 3 drives the support rod 4 to slide in the through groove 2, so that the extrusion plate 5 is restricted by the limiting connecting rod 7. At the same time, the support rod 4 supports the extrusion plate 5 outward to keep the extrusion plate 5 away from the cylindrical tube 1. When the extrusion plate 5 fits the inner wall of the metal tube, it is supported by the support rod 4 to automatically adjust the contact angle between the extrusion plate 5 and the metal tube to ensure that the metal tube is stably supported by the extrusion plate 5.
