Description

Technical Field

[0001] The utility model relates to the field of rust removal of galvanized parts, in particular to a surface rust removal device for galvanized parts. Background Art

[0002] A galvanized sheet refers to a steel sheet with a layer of zinc plated on its surface. Galvanizing the outer surface of the steel sheet is an economical and effective rust prevention method. Before galvanizing the steel sheet, it is necessary to polish and remove rust from the raw material of the steel sheet, and the rust removal effect directly affects the quality and appearance of the galvanized steel sheet. If the rust cannot be polished clean, the zinc layer on the galvanized steel sheet is likely to fall off, resulting in unqualified products.

[0003] Chinese Patent No. CN206484395U discloses a rust removal device for galvanized steel sheets before plating, including a frame and a PLC controller. Columns are vertically and fixedly installed in the middle of the outer side walls of both sides of the frame. A cross beam is fixedly connected between the tops of the columns. A ball screw is arranged inside the cross beam. A servo motor is fixedly installed at one end of the cross beam. One end of the ball screw penetrates the cross beam and is in transmission connection with the servo motor. A screw nut is threadedly connected to the outer surface of the ball screw. A rust removal motor is fixed to the bottom of the screw nut. The PLC controller is fixedly installed on the surface of the outer side wall of the frame. This rust removal device for galvanized steel sheets before plating realizes automatic operation of the entire rust removal process through the PLC controller, greatly saves working time, improves work efficiency and the production efficiency of enterprises, and at the same time reduces the harm to the physical health of workers caused by dust during the rust removal process, and is worthy of promotion. However, this rust removal device still has the following problems: This device can only polish and grind a single part at a time, and after polishing, it is necessary to manually disassemble the galvanized steel sheet, which not only affects work efficiency but also wastes labor and materials. Therefore, its practicability is poor and its applicable scope is limited. Content of the Utility Model

[0004] The purpose of the utility model is to solve the above defects and provide a surface rust removal device for galvanized parts.

[0005] The object of the present utility model is achieved in the following manner: A surface rust removal device for galvanized parts, comprising a machine table, two grinding mechanisms and two conveying mechanisms. The two grinding mechanisms are both installed on the machine table. There are two installation channels on the machine table, and the conveying mechanisms are installed on the installation channels. A number of movable installation molds are installed on the conveying mechanisms. An installation groove for installing galvanized parts is provided on the installation mold. Guide block one, guide block two and guide block three are installed on the inner wall of the installation channel. Guide block one is installed at one end of the installation channel. Guide block two is installed below the conveying mechanism and above guide block one. Guide block three is installed at one end close to the conveying mechanism and above guide block one. Three collision rods are installed on the inner wall of the installation channel.

[0006] Further, the grinding mechanism includes a support frame, a lifting plate, two lifting motors, two adjusting screws, two grinding wheels and two rotating motors. The two lifting motors and the two adjusting screws are both installed at both ends of the support frame. One end of the adjusting screw penetrates the support frame and is connected to the lifting motor. Both ends of the lifting plate are sleeved on the adjusting screws. The rotating motor is installed on the lifting plate. The rotating motor is connected to the lifting plate through a rotating shaft. The grinding wheel is sleeved on the rotating shaft. By setting two polishing mechanisms, the galvanized parts can be roughly polished once and then finely polished once. Two channels can polish the galvanized parts simultaneously through the two grinding wheels.

[0007] Further, a protective frame is installed on the rotating motor. By setting the protective frame, the motor can be prevented from being bumped. A mating groove corresponding to the protective frame is provided on the machine table.

[0008] Further, the conveying mechanism is composed of a conveying motor, a number of conveying shafts and a conveyor belt. The conveyor belt is sleeved on the conveying shafts. One end of the conveying shaft is connected to the conveying motor. The conveying motor drives the conveying shaft to rotate, and the conveying shaft drives the conveyor belt to move back and forth.

[0009] Further, the installation mold is installed on the conveyor belt through a movable shaft. The installation mold can be flipped on the conveyor belt through the movable shaft.

[0010] Further, an installation hole for mating with the galvanized part is provided on the installation groove. An installation column matched with the installation hole is installed on the galvanized part. The installation column can be installed on the installation hole.

[0011] Further, soft pads are installed on guide block one, guide block two and guide block three. The partial impact force during the collision of the galvanized parts can be reduced through the soft pads.

[0012] Further, the first guiding block, the second guiding block, and the third guiding block are respectively provided with a first inclined surface, a second inclined surface, and a third inclined surface for guiding the workpiece. By providing the first inclined surface, the second inclined surface, and the third inclined surface on the first guiding block, the second guiding block, and the third guiding block respectively, the galvanized parts can be guided to slide.

[0013] Further, the collision rod is made of a soft material. By providing a soft collision rod, the wear on the installation mold caused by the collision with the installation mold can be reduced.

[0014] The beneficial effects of the present utility model are as follows: By providing a movable installation mold, the galvanized parts are installed in the installation groove of the installation mold for polishing. The installation mold after polishing will flip during the transmission process. By providing a collision rod to collide with the flipped installation mold, the galvanized parts will fall off from the installation groove. By providing the third guiding block to guide the fallen galvanized parts to slide onto the first guiding block, the galvanized parts that did not fall in the early stage will fall onto the second guiding block by hitting the collision rod in the later stage and then be guided by the second guiding block to fall onto the first guiding block. There is no need for manual disassembly, which is beneficial to improving work efficiency, saving manpower and material resources. Therefore, it has strong practicability and a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS
