Description

Automatic production line capable of improving thermal spraying quality of pots and pots thermal spraying method

technical field

The invention belongs to the technical field of thermal spraying, and in particular relates to an automatic production line for improving the quality of cookware coated with a magnetically conductive metal layer and a method for improving the quality of cookware thermal spraying.

Background technique

With the improvement of energy saving, environmental protection, sanitation and other standard requirements, iron pans have been gradually eliminated by the market. The current pans are mainly made of double-layer or multi-layer alloy materials, but these materials are non-magnetic materials and cannot be used directly. When used on an induction cooker, the scope of use is limited. Therefore, it is necessary to coat the bottom of the pan with a magnetically conductive metal layer to achieve magnetic conduction. can be used.

In the prior art, the method of coating the magnetically conductive metal layer is mainly the process method of electric arc thermal spraying, which uses flame, plasma flame flow, electric arc (such as heat sources to heat powdery or filamentous, or rod-shaped solid materials to The melting material in molten or semi-molten state is accelerated or atomized to form high-speed droplets, which hit the substrate at high speed, and are rapidly cooled and solidified to deposit on the surface of the substrate to form a covering layer.

The Chinese utility model patent of authorization announcement number CN214168103U discloses a kind of circular electric arc spraying pan production line, which includes a noise-absorbing maintenance room, a sound-proof spraying room, a manipulator, a spray gun and a frame, and sprockets are arranged at intervals on the frame, An endless chain is arranged on the sprocket, the wheel shaft of the sprocket is vertically arranged, and a tray is arranged on the upper end of the wheel shaft, and a pot is placed on the tray, and the frame and the endless chain are separated from the sound-absorbing The maintenance room and the sound-proof spray room are provided with the manipulator in the sound-proof spray room, the spray gun is set on the manipulator, and the pot rotating device is set in the sound-proof spray room, and the pot rotates The device enables the pot to rotate by itself when spraying. The utility model uses the endless chain as the driving force, can continuously spray the pots, realizes continuous production, and improves work efficiency.

In this production line, the center of the tray is connected to the wheel shaft, and the wheel shaft is connected to the chain link. In actual operation, the tray rotates under the force of the pot rotating device, and the spray gun is aligned and set for spraying under the synchronous movement of the manipulator. At this time, the rotation of the tray needs to be relatively stable. If there is an eccentric rotation, the pot will shake, which will cause part of the sprayed molten material to be sprayed outside the preset range, resulting in waste. At the same time The eccentric rotation shake also affects the uniformity of the parts that need to be sprayed. In this technical solution, the rotating tray needs to be attached to the stability of the endless chain, and the endless chain is only stabilized by the state of tension, but the structure of the chain is It consists of multiple chain links that can rotate with each other. Therefore, the stability provided by the chain itself is limited. When the pan rotating device exerts force on the surrounding surface to drive the rotation, the chain will definitely shake and sway. In addition, there is no pan in the tray. The component that can fix the pot, after turning, the position of the pot in the tray is not fixed as a guarantee, and there is a possibility of rotation and slippage. Under these two factors, the uniformity of the sprayed magnetic conductive metal layer is generally not ideal. This kind of pot can be used on the induction cooker for a short period of time, and it seems that there is no difference between good and bad, but after a long period of use, after a certain deformation of the bottom of the pot, a magnetically conductive metal layer with uneven thickness is easy to appear. Poor contact will affect the service life of the pot.

In summary, compared with the prior art, the present invention has the following advantages:

The present invention is an improvement to the existing production line in terms of clamping.

Its clamping device first ensures that the carrying base is absolutely stable during spraying, and then designs a mold base (adjacent mold) of the same size as the backing of the pot clamping, using the shape and gravity of the pot itself to achieve a natural fit , because the thermal spraying of the pot is a process after the pot is formed, at this time the edge of the pot still has a certain flanging (the flanging is removed in the subsequent process), for this reason, use the compression flanging A self-centering pressing device is designed in the way, the core of the pressing device is to design a set of pressing action assembly in the abutment mold, and a movable shaft is designed in the abutment mold and in the island platform Design a guide groove, and set bosses of different heights in different positions in the guide groove to cooperate with the movable shaft to drive different functions. When the movable shaft is in the soundproof spraying room, the upward movement of the movable shaft drives the compression combination pieces, so that the multiple assemblies are moved towards the center of the circle synchronously under the tension of the tension spring. Positioning, and when the sprayed pot needs to be removed, the pot only needs to leave the soundproof spraying room, and the pressing action will be invalid, and the pot can be removed manually or with a suction cup without other additional operations, and if further It is necessary to use a mechanical method to lift the pot from below, then design a boss with a certain height in the guide groove, that is, use the height of the movable shaft to give a thrust to the bottom of the pot, and benefit from the pressing action here. With the tension of the tension spring and the contact method of the inclined surface, the pot can break through the compressed state by itself when it rises, without hindering the rise of the pot. Similarly, this feature can also be used to actively pick up the pot when feeding.

It can be seen that the overall assembly line of the present invention does not slow down while realizing different functions and enhancing stability, which is a significant improvement compared with the prior art.

S4. The carrying platform 204 carries the sprayed pot 1 to the area of the unloading assembly 500, that is, the third boss 08, and the movable shaft 205 rises upward when the universal ball 04 collides with the boss. During the process, the pot 1 Although the pressed actuator 730 is in the pressed state, its pressing force comes from the tension of the pressing tension spring 740, and when the front of the pot bottom of the pot 1 is pushed up by the lifting platform 05 in the movable shaft 205 After lifting, its jacking force is easy to overcome the tension of the compression spring 740, and the compression actuator 730 is in contact with the edge of the pot 1 on an inclined plane, and it will not appear during the process of overcoming the tension of the compression spring 740. Therefore, after the pot 1 is lifted by the jacking platform 05 at this position, the edge of the pot 1 is separated from the turntable 206 by a certain distance, and the blanking assembly 500 can use a suction cup to suck the pot from the upper part. Tool 1, also can adopt forklift arm to insert from the distance that both separates and take away pot 1 with the mode of hoisting.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which the present invention belongs can make various modifications or supplements to the described specific embodiments or adopt similar methods to replace them, but they will not deviate from the spirit of the present invention or go beyond the definition of the appended claims range.
