Technical Field

The invention relates to the technical field of stamping part surface treatment, and in particular to a metal stamping part surface treatment device and a treatment method.

Background Art

Surface treatment of metal stamping parts refers to a series of surface treatment processes for metal parts obtained through stamping. These processes are aimed at improving the appearance, performance, corrosion resistance, wear resistance, etc. of metal stamping parts to meet different usage needs. Among them, surface polishing is to polish the surface of metal stamping parts to remove burrs and uneven parts on the surface to make it smoother and flatter. Polishing can improve the appearance quality and performance of metal stamping parts.

The Chinese patent discloses: a surface treatment device for metal stamping parts, patent application number: 201911151745.7, which "includes a base plate, the upper surface of the base plate includes a support column, the bottom end of the support column is fixedly connected to the upper surface of the base plate, the right side of the support column includes a crossbeam, the right end of the crossbeam includes a motor, the left side of the motor overlaps the right end of the crossbeam, and the output end of the motor includes a grinding disc, and the upper surface of the grinding disc is fixedly connected to the output end of the motor."

Although the device solves the problem that the existing metal stamping surface treatment device is not easy to disassemble, making the motor difficult to repair when it is damaged, the device only clamps and fixes the stamping parts through a simple clamp block, and cannot fix stamping parts of different sizes. It only fixes the two sides of the stamping parts through the clamp block, which easily leads to insufficient clamping. The stamping parts may vibrate or move during polishing, thereby affecting the polishing quality and efficiency, reducing the overall efficiency of production. At the same time, the device cannot spray water to cool down and remove dust on the stamping parts during polishing, resulting in the heat and metal dust generated during the polishing process. The influence on product quality and equipment life. During the polishing process, the high-speed friction between the metal stamping parts and the polishing wheel will generate a lot of heat. If the cooling treatment is not carried out in time, it may cause thermal deformation or oxidation on the surface of the stamping parts. At the same time, if the metal dust generated during the polishing process is not cleaned up in time, it will not only affect the polishing effect, but also may damage the polishing disc and stamping parts, and even pose a threat to the health of the operator.

Beneficial effects of the present invention:

1. A surface treatment device and method for metal stamping parts, through the clamping mechanism, rotates a rotating support rod close to one side of the water tank, and then the rotating support rod rotates to drive the worm, and when the worm rotates, it drives the worm wheel to rotate, and then the worm wheel drives the rotating disk to rotate, and when the rotating disk rotates, it drives the cylindrical rod to slide inside the arc groove through the arc groove, and then the cylindrical rod drives the sliding plate to slide in the first sliding groove and extend to the outside of the support plate, and then one end of the sliding plate drives one end of the clamping plate to rotate, and when one end of the clamping plate rotates, The other end of the clamping plate is driven to rotate and the movable plate is pushed to move toward the stamping part, so that the clamping block can clamp the four sides of the stamping parts of different sizes, making the clamping more stable and adaptable to stamping parts of different sizes.

At the same time, the clamping block can clamp the stamping parts from four directions to ensure that the stamping parts remain stable during the processing and prevent position displacement or sliding due to vibration or external force, thereby ensuring processing accuracy and clamping flexibility and reliability, and facilitating use.

2. A surface treatment device and method for metal stamping parts, through the water spray mechanism, the servo motor drives the arc-shaped grinding disc to rotate, and then the arc-shaped grinding disc will polish the surface of the stamping part. At this time, the rotating column will drive the small gear to rotate at the same time.

Then the large gear will drive the reciprocating screw in the middle part to rotate. When the reciprocating screw rotates, it will drive the reciprocating rod to move up and down. At this time, one end of the reciprocating rod will drive the rubber extrusion sheet to stretch to the bottom. When the rubber extrusion sheet stretches, it will absorb the water inside the water tank and enter the extrusion chamber through the first one-way valve due to the lack of air inside the extrusion chamber. The water in the water tank enters the extrusion chamber through the first one-way valve, and the water in the extrusion chamber cannot flow back into the water tank. When the reciprocating rod moves upward The rubber extrusion sheet will be squeezed, and the rubber extrusion sheet will squeeze the water inside the extrusion chamber, and then the water will flow to the drain pipe through the second one-way valve. The water can only flow into the drain pipe through the second one-way valve to avoid water backflow, and the arc grinding disc and stamping parts are sprayed through the spray head at one end of the drain pipe, so as to reduce the heat generated during the polishing of the arc grinding disc and the stamping parts, avoid thermal deformation of the stamping parts caused by overheating, thereby ensuring the accuracy and quality of the product. At the same time, water spraying can effectively absorb and remove metal dust generated during the polishing process, prevent dust from accumulating on the stamping parts and the arc grinding disc, reduce the impact of dust on the polishing surface, keep the working area clean, improve product quality and equipment life, and also improve the working environment and reduce the impact on the health of operators.

3. A surface treatment device and method for metal stamping parts, three extrusion springs are fixedly connected inside the limit block, one end of the three extrusion springs is fixedly connected to the bottom of the stamping part base, through the action of the extrusion springs, when the stamping part contacts the arc-shaped grinding disk, the stamping part base is squeezed by the spring force of the extrusion springs themselves, and then the stamping part base squeezes the stamping part and fits the surface of the arc-shaped grinding disk, thereby improving the polishing accuracy of the stamping part, avoiding the phenomenon of incomplete surface polishing, and further improving the polishing accuracy.
