Description

Technical Field

[0001] This utility model relates to the field of sintering equipment technology, specifically to a titanium alloy glass sintering device. Background Technology

[0002] In the field of titanium alloy glass sintering, traditional powder metering devices mostly adopt volumetric metering (such as screw conveying at a constant speed), but titanium alloy powder (density 4.5 g / cm³) is not suitable for this purpose. 3 ) and glass powder (density 2.5 g / cm³) 3 The large density differences and the fact that powder flowability is affected by humidity and particle size can lead to a deviation of more than ±2% between the actual feed amount and the theoretical value. Manual feeding or empirical control can easily cause imbalance in the proportions, which directly affects the microstructure of the sintered body (such as uneven distribution of the glass phase leading to stress concentration at the interface), ultimately resulting in fluctuations in the mechanical properties (such as shear strength) of the sintered parts or an increase in the scrap rate. Utility Model Content

[0003] The purpose of this invention is to provide a titanium alloy glass sintering apparatus to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A titanium alloy glass sintering apparatus includes a mixing tank, a titanium alloy powder adding component, and a glass powder adding component. The glass powder adding component includes a screw conveyor. The feed end of the screw conveyor is fixedly connected to a glass powder storage tank via a pipe. The discharge end of the screw conveyor is fixedly connected to a weighing pipe. A drive motor is provided at one end of the screw conveyor.

[0006] A weighing sensor is fixedly connected to the bottom of the inner wall of the weighing tube, and an air jet pipe is fixedly connected to the right side of the weighing tube. A material blocking air jet pipe is fixedly connected to the top of the end of the air jet pipe near the weighing tube, and the end of the material blocking air jet pipe away from the air jet pipe extends into the interior of the weighing tube.

[0007] A further improvement of this utility model is that a discharge pipe is fixedly connected to the side of the weighing tube near the bottom, and the end of the discharge pipe away from the weighing tube is fixedly connected to the top of the mixing tank.

[0008] The above technical solution involves installing bag filters on the top of the glass powder storage tank, titanium alloy powder storage tank, and mixing tank, which are connected to the tank body via pipes to collect the generated dust.

[0009] A further improvement of this utility model is that the jet direction of the material-blocking jet pipe is parallel to the vertical axis of the weighing tube.

[0010] A further improvement of this utility model is that the titanium alloy powder addition component and the glass powder addition component have the same structure.

[0011] A further improvement of this utility model is that an ion copper rod is fixedly connected to the inner wall of the weighing tube.

[0012] A further improvement of this utility model is that: an air pump is fixedly connected to the end of the jet pipe away from the weighing pipe, and an electromagnetic valve is fixedly connected to the outer wall of the jet pipe.

[0013] Using the above technical solution, all electrical equipment (such as drive motors, air pumps, solenoid valves, etc.) are grounded, and an emergency stop button is installed on the operation panel.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. This utility model provides a titanium alloy glass sintering device. The air curtain design of the jet pipe and the material-blocking jet pipe forms a directional airflow, which can quickly blow the powder on the surface of the weighing sensor into the discharge pipe, avoiding powder residue caused by traditional gravity feeding (residual amount ≤5g / batch). At the same time, the parallel air curtain of the material-blocking jet pipe (parallel to the vertical axis of the weighing tube) prevents powder from splashing backward, ensuring that 100% of the material enters the mixing tank, improving material utilization and reducing production costs.

[0016] 2. This utility model provides a titanium alloy glass sintering device. The integrated design of the ion copper rod can neutralize the electrostatic charge of the powder in the weighing tube in real time (static voltage ≤100V), preventing the titanium alloy powder and glass powder from agglomerating due to electrostatic adsorption (agglomerated particles ≤50μm), ensuring that the two powders are evenly dispersed in the subsequent mixing process (mixing index ≥95%). Static elimination also prevents powder from adsorbing on the inner wall of the equipment, reducing the cleaning frequency and improving production efficiency.

[0017] 3. This utility model provides a titanium alloy glass sintering device. The device achieves precise quantitative feeding of powder through the linkage control of a weighing sensor and a screw conveyor. When the weighing sensor detects that the powder in the weighing tube has reached the preset weight, the control system automatically stops the screw conveyor, avoiding the ratio error caused by manual intervention. This ensures that the mass ratio of titanium alloy powder to glass powder is accurate to within ±0.5%, meeting the stringent requirements of high-end sintering processes for material ratio.

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] Example 1

[0026] like Figure 1-4 As shown, this utility model provides a titanium alloy glass sintering device, including a mixing tank 1, a titanium alloy powder adding component 2, and a glass powder adding component 3. The glass powder adding component 3 includes a screw conveyor 5, the outer shell of which is made of carbon steel, and the screw conveying rod is made of stainless steel. The feed end of the screw conveyor 5 is fixedly connected to a glass powder storage tank 4 via a pipe. The glass powder storage tank 4 is made of plastic. The discharge end of the screw conveyor 5 is fixedly connected to a weighing pipe 7. A drive motor 6 is installed at one end of the screw conveyor 5.

[0027] A weighing sensor 13 is fixedly connected to the bottom of the inner wall of the weighing tube 7. An air jet pipe 10 is fixedly connected to the right side of the weighing tube 7. The diameter of both the air jet pipe 10 and the material blocking air jet pipe 12 is 20mm. The material blocking air jet pipe 12 is fixedly connected to the top of the end of the air jet pipe 10 near the weighing tube 7. The end of the material blocking air jet pipe 12 away from the air jet pipe 10 extends into the interior of the weighing tube 7.

[0028] A discharge pipe 8 is fixedly connected to the side of the weighing tube 7 near the bottom, and the end of the discharge pipe 8 away from the weighing tube 7 is fixedly connected to the top of the mixing tank 1.

[0029] The mixing tank 1 can be equipped with a stirring device, such as a stirring paddle. The stirring paddle can adopt a three-blade structure and be driven by a motor. The motor power can be set to 1.5kW, and the stirring speed can be adjusted within the range of 50-200r / min to ensure that the titanium alloy powder and glass powder are fully mixed.

[0030] Example 2

[0031] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the jet direction of the material blocking jet pipe 12 is parallel to the vertical axis of the weighing pipe 7.

[0032] The titanium alloy powder adding component 2 and the glass powder adding component 3 have the same structure, including components such as a titanium alloy powder storage tank, a screw conveyor, and a weighing tube. The material and size of each component are the same as those of the glass powder adding component 3.

[0033] An ionized copper rod 14 is fixedly connected to the inner wall of the weighing tube 7.

[0034] An air pump 9 is fixedly connected to the end of the jet pipe 10 away from the weighing pipe 7, and a solenoid valve 11 is fixedly connected to the outer wall of the jet pipe 10.

[0035] The working principle of this titanium alloy glass sintering device will be explained in detail below.

[0036] like Figure 1-4 As shown, when adding glass powder to the mixing tank 1, the drive motor 6 is first started by pressing the start button on the operation panel. This drives the screw conveyor 5 to transport the glass powder from the glass powder storage tank 4 to the weighing tube 7. As the glass powder is gradually added to the weighing tube 7, the weighing sensor 13 weighs the powder. When the appropriate weight is reached, the signal is fed back to the control system based on the PLC. The control system then controls the screw conveyor 5 to stop conveying. After that, the control system starts the air pump 9. After a 1-second delay, the solenoid valve 11 is opened. The air pump 9 sprays compressed air parallel to the weighing tube 7 through the jet pipe 10, blowing the glass powder on the weighing sensor 13 into the discharge pipe 8, and then into the mixing tank 1 through the discharge pipe 8. A portion of the air in the jet pipe 10 is sent to the blocking jet pipe 12, forming a downward closed air curtain. This allows the powder to be quickly delivered into the mixing tank 1 through the discharge pipe 8 without being dispersed into the weighing tube 7 by the blowing of the jet pipe 10. The titanium alloy powder addition process in titanium alloy powder addition component 2 is the same as that in glass powder addition component 3.
