Description

Technical Field

[0001] The invention relates to the technical field of parts spraying, in particular to a novel mold steel surface plasma spraying strengthening device. Background Art

[0002] As an important material in industrial production, the surface properties of mold steel directly affect the service life and production efficiency of the mold. Traditional surface treatment methods such as electroplating and thermal spraying have disadvantages such as low coating bonding strength, high porosity and complex process. Plasma spraying technology has become an important means of mold steel surface strengthening due to its high energy density, rapid cooling and excellent coating performance. The surface plasma spraying device is a high-performance surface treatment equipment. It generates a high-temperature, high-speed plasma jet through a plasma spray gun, instantly heats the spraying material to a molten or semi-molten state, and sprays it onto the workpiece surface at a very high speed. The device can form a dense, high-bonding strength coating on the workpiece surface, effectively improving the wear resistance, corrosion resistance, high temperature resistance and other properties of the workpiece. It is widely used in aerospace, automobile manufacturing, petrochemical and other fields, and plays an important role in improving product quality and service life; In the prior art, surface plasma spraying equipment fixes mold steel and then sprays the coating on the mold steel. However, many fixing devices can only adapt to mold steel of specific size and shape, lacking flexibility. In addition, during the existing plasma spraying operation, there is no special protective structure or the protective structure is imperfect. On the one hand, the spraying material is easy to fly into the surrounding environment, causing material waste and polluting the working environment. Summary of the invention

[0005] Preferably, the protective component includes two electric push rods, which are fixedly connected to the inner top side of the bottom box, and a movable plate is fixedly connected to the left side of the two electric push rods. The front and rear ends of the movable plate are rotatably connected to rotating rods, and the ends of the two rotating rods away from the movable plate are rotatably connected to connecting rods, the tops of the two connecting rods are fixedly connected to protective shells, and the tops of the two protective shells are installed with rectangular shells.

[0006] Preferably, the drying assembly comprises a protective plate, the protective plate is fixedly connected to the middle side of the top of the top box, and a heating plate is fixedly connected to the inner middle side of the protective plate.

[0007] Preferably, a plurality of evenly distributed fans are fixedly connected to the top of the protective plate, and a heating tube is fixedly connected to the bottom of the protective plate.

[0008] Preferably, the front and rear sides of the two movable blocks are fixedly connected to limit blocks.

[0009] Preferably, a sliding block is fixedly connected to the left sides of the two connecting rods, and a sliding groove is provided on the left side inside the bottom box.

[0010] Preferably, the two sliding blocks are both slidably connected inside the sliding groove.

[0011] Preferably, the two protective shells are respectively slidably connected to the front and rear sides of the circular mold steel, and the bottom of the spray plate is slidably connected to the top of the rectangular shell.

[0012] Preferably, both the front and rear sides of the interior of the fixed box are fixedly connected with limit rods, and the two limit blocks are slidably connected to the outer peripheries of the two limit rods respectively.

[0013] Preferably, the left and right ends of the top of the heating tube are fixedly connected to the left and right sides of the heating plate respectively.

[0014] Working principle: When performing surface spraying processing on circular mold steel, first open the front door of the top box, then start the electric push rod 1, which controls the horizontal plate to move to the left, so that the two concave blocks move oppositely along the two movable blocks respectively, so that the two movable blocks move in opposite directions, and then the two mounting blocks drive the two arc clamping blocks to move in opposite directions respectively, and then the circular mold steel is placed between the two arc clamping blocks, and then start the electric push rod 1 again to move the horizontal plate to the right, at this time the two movable blocks move towards each other, and then the two mounting blocks drive the two arc clamping blocks to move towards each other respectively, so as to fix the circular mold steel, and then adjust the distance between the two positioning seats so that the positioning seat on the left side contacts the left end of the circular mold steel; Then, the electric push rod 2 is started, and the electric push rod 2 controls the moving plate to move to the right. When the moving plate moves to the right, the rotating rods at the front and rear ends of the moving plate rotate relatively. When the two rotating rods rotate relatively, the two connecting rods can be controlled to move. Because the two sliders move toward each other in the slide groove, the two connecting rods drive the two protective shells to move toward each other. After the two protective shells and the rectangular shell contact and cooperate with each other, the mechanical arm can be started to drive the spraying plate and the plasma nozzle to move. After the bottom of the spraying plate contacts the top of the rectangular shell, the conveying pipe and the plasma nozzle can be started to spray the coating. During spraying, the motor in the positioning seat can be started to rotate the circular mold steel, so as to spray evenly. Finally, after the spraying is completed, the robotic arm is started to move the spray plate and the plasma nozzle out of the rectangular shell, and then the electric push rod 2 is started again. The electric push rod 2 controls the moving plate to move to the left, and then the two connecting rods rotate in opposite directions, so that the two connecting rods move in opposite directions. After the two protective shells and the rectangular shell are separated, the heating plate can be started. The heating plate heats the heating liquid in the heating tube and starts the fan synchronously to form a hot air flow, which can heat and dry the coating on the surface of the circular mold steel. Finally, the work is completed and the circular mold steel is taken out.

[0015] The present invention provides a novel mold steel surface plasma spraying strengthening device, which has the following beneficial effects: 1. The present invention adjusts the distance between the two mounting blocks through the fixing assembly and the mounting blocks can be installed with different clamps, thereby allowing different types of mold steels to be fixed and plasma sprayed on different types of mold steels. After the mold steel is fixed, the mold steel can be rotated for uniform spraying.

[0016] 2. The present invention allows two protective shells to be used in conjunction with each other through the protective assembly, thereby preventing the spraying material from scattering when spraying the mold steel, and the relatively movable protective shell can be replaced according to the mold steel.

[0017] 3. The present invention can make the fan control the airflow to flow through the heating tube to form hot air through the drying component, so that the hot air flows to the tool steel after the spraying work is completed, so that the sprayed coating can solidify quickly.
