Description

Technical Field

[0001] The utility model relates to the technical field of powder metallurgy, in particular to a forming and conveying device. Background Art

[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder or a mixture of metal powder and non-metallic powder as raw material, and then forms and sinters it to manufacture metal materials, composite materials and various types of products. At present, powder metallurgy technology has been widely used in transportation, machinery, electronics, aerospace, weapons, biology, new energy, information and nuclear industries, becoming one of the most dynamic branches of new materials science. Powder metallurgy technology has a series of advantages such as significant energy saving, material saving, excellent performance, high product precision and good stability.

[0003] During the manufacturing process, powder metallurgy pistons undergo a molding process, which requires a conveying device. Existing conveying devices used for piston molding typically focus solely on the product's conveying function, paying less attention to surface cleaning. Some conveying devices may not have dedicated cleaning equipment, resulting in the molded product carrying dust and impurities into subsequent processes during the conveying process. This not only affects the product's appearance quality but can also adversely affect subsequent processing techniques (such as sintering and surface treatment). For example, if dust is sintered with the product during the sintering process, it may affect the product's density and performance uniformity. During surface treatment, dust may prevent the treatment agent from fully contacting the product surface, reducing the surface treatment effect.

[0004] Therefore, we propose a forming and conveying device based on powder metallurgy piston. Utility Model Content

[0005] The purpose of the present utility model is to solve the shortcomings existing in the prior art. Conventional powder metallurgy piston-based forming and conveying devices usually only focus on the conveying function of the product, but pay less attention to the cleaning treatment of the product surface. Some conveying devices may not have special cleaning equipment, resulting in the molded products entering the subsequent process with dust and impurities during the conveying process. This will not only affect the appearance quality of the product, but may also have an adverse effect on the subsequent processing technology (such as sintering, surface treatment, etc.). For example, if dust is sintered together with the product during the sintering process, it may affect the density and performance uniformity of the product; during surface treatment, dust may hinder the full contact between the treatment agent and the product surface, reducing the surface treatment effect.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A forming and conveying device based on a powder metallurgy piston includes a conveyor belt body, a plurality of supporting feet are provided at the bottom of the conveyor belt body, a connecting plate is provided near the left side and between two adjacent supporting feet, a fixed support seat is provided on the top of the connecting plate, a side soot blowing assembly is installed on the top of the fixed support seat, and a top soot blowing assembly is also provided on the top of the conveyor belt body.

[0008] As a preferred solution of the present invention, the side sootblowing assembly includes a mounting shell, a mounting cavity is defined inside the mounting shell, and a plurality of first mounting seats are installed inside the mounting cavity.

[0009] As a preferred solution of the present invention, a first air pump is installed on the top of several of the first mounting seats, a blowing pipe is provided at the connection of several of the first air pumps, and several blowing ports are installed on several of the blowing pipes.

[0010] As a preferred solution of the present invention, filter screens are provided at the left and right openings of the installation shell, and the filter screens are fixed to the installation shell by adsorption via magnets.

[0011] As a preferred solution of the present invention, the top sootblowing assembly includes a top mounting seat, a diversion chamber is installed inside the top mounting seat, and a plurality of blowing nozzles are provided at the bottom of the diversion chamber.

[0012] As a preferred solution of the present invention, a guide tube is installed on the top of the diversion chamber, and a connecting piece is provided at the connection of the guide tube.

[0013] As a preferred solution of the present invention, an output pipe is provided at the connection of the connecting piece, a second air pump is connected to the right side wall of the output pipe, and a second mounting base is installed at the bottom of the second air pump.

The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0025] Example

[0026] like Figure 1-4 As shown, the present invention provides a technical solution: the conveyor belt body 1 is the core load-bearing component of the entire powder metallurgy piston-based molding and conveying device. It is responsible for the continuous and stable transportation of powder metallurgy molded products during the production process. The conveyor belt body 1 is typically made of high-strength, wear-resistant, and flexible materials to accommodate long-term operation and the transportation of products of varying weights and shapes. Its surface is typically specially treated to provide a certain degree of anti-slip and wear resistance, ensuring that products do not slip or wear during transportation.

[0027] Support legs 2 are located at the bottom of the conveyor body 1, supporting and stabilizing the entire conveyor system. The number and layout of support legs 2 are designed based on the length, width, and load capacity of the conveyor. Generally, support legs 2 are made of sturdy metal, such as steel, for excellent load-bearing capacity and stability. They are secured to the bottom frame of the conveyor body 1 by welding or bolting, ensuring they do not shift or wobble due to vibration or the weight of the product during transport. Each support leg 2 is precisely machined and adjusted to ensure consistent height, ensuring the conveyor body 1 maintains horizontal operation, which is crucial for smooth product transport. A connecting plate 3 is located near the left side, between two adjacent support legs 2. This plate enhances the stability and connectivity of the local structure. It connects adjacent support legs 2, forming a more stable support structure that can better withstand the various forces generated by the conveyor during operation, such as tension, compression, and torsion. The connecting plate 3 also provides a reliable mounting platform for subsequent installation of other components.

[0028] The mounting shell 5 is the external protective structure of the side sootblowing assembly. It not only provides installation space for the various internal components, but also plays a role in protection and sealing. The mounting shell 5 is usually made of metal, such as aluminum alloy or stainless steel, which has a certain strength and corrosion resistance and can adapt to various factors in the powder metallurgy production environment, such as dust, moisture, etc. The mounting cavity 6 opened inside it is specially designed to accommodate and fix other components. The size and shape of the mounting cavity 6 are reasonably planned according to the size and layout of the internal components to ensure that each component can be accurately installed and operate normally. The design of the mounting cavity 6 also takes into account the rationality of air flow to facilitate the uniform distribution and discharge of the sootblowing gas.

[0029] The first mounting base 7 is a basic component for fixing the first air pump 8. It is usually made of strong materials and has good stability and shock resistance. The design of the first mounting base 7 must match the appearance and installation requirements of the first air pump 8 to ensure that the air pump can be firmly installed on it and will not loosen or shift during operation. The first air pump 8 is the core power source of the side soot blowing assembly. It is responsible for generating high-pressure gas to blow away the dust on the side of the product. The working principle of the first air pump 8 is to drive the impeller to rotate through the motor, suck in and compress the air, and then discharge the high-pressure gas through the blowing pipe 9. The setting of multiple first air pumps 8 can provide more powerful soot blowing power to ensure that the dust on the side of the product can be effectively removed. According to different production needs and product characteristics, first air pumps 8 with different power and performance can be selected to achieve the best soot blowing effect.

[0030] The air blow pipe 9 connects the first air pump 8 to the air blow ports 10, responsible for delivering the high-pressure gas generated by the first air pump 8 to the air blow ports 10. The air blow pipe 9 is typically made of pressure-resistant and corrosion-resistant materials, such as rubber or plastic tubing. Its diameter and length are carefully selected based on the air pump's output pressure and the layout of the air blow ports 10 to minimize pressure loss during gas delivery and ensure even distribution to each air blow port 10. The air blow ports 10 are the direct active components of the side sootblowing assembly, blowing high-pressure gas at a specific speed and direction onto the sides of the product, dislodging dust. The number and distribution of air blow ports 10 are designed based on the size and shape of the product and the amount of dust accumulation, ensuring comprehensive coverage of the product's sides and eliminating any blind spots. The shape and angle of the air blow ports 10 are also carefully designed to achieve optimal sootblowing results. For example, a bell-shaped air blow port 10 increases the gas discharge area, while adjusting the angle of the air blow port 10 allows the gas to better conform to the product's side shape, improving sootblowing efficiency.

[0031] The filter 11 is arranged at the left and right openings of the mounting shell 5. Its main function is to prevent dust and other impurities from entering the interior of the side soot blowing assembly and to protect the normal operation of the first air pump 8 and other components. The filter 11 is usually made of a fine metal mesh or fiber mesh, has good filtering performance, and can block dust particles in the air. The filter 11 and the mounting shell 5 are fixed by adsorption through magnets. This fixing method is convenient and fast, and facilitates the installation and removal of the filter 11, and is convenient for regular cleaning and replacement of the filter 11 to ensure the filtering effect of the filter 11. When the side soot blowing assembly is working, the outside air will enter the interior of the mounting shell 5 through the filter 11, and after being compressed by the first air pump 8 and transported by the air pipe 9, it will be blown out from the air port 10 to act on the side of the product. Impurities such as dust will be blocked outside by the filter 11, thereby ensuring the cleanliness of the interior of the soot blowing assembly and extending the service life of the equipment.

[0032] The top mounting seat 12 is the installation base of the top sootblowing assembly. It is responsible for fixing the entire top sootblowing assembly to the appropriate position on the top of the conveyor belt body 1 so that the upper surface of the product can be sootblown. The top mounting seat 12 is usually made of a sturdy metal material with good stability and load-bearing capacity. Its design must take into account the connection method with the conveyor belt body 1 and the overall layout of the top sootblowing assembly to ensure that it can be firmly installed on the conveyor belt and will not interfere with the transportation of the product. The shape and size of the top mounting seat 12 are customized according to the specific structure of the top sootblowing assembly and the actual situation of the conveyor belt to achieve the best installation effect and sootblowing effect.

[0033] The diverter chamber 13 is an important component in the top sootblowing assembly. Its function is to divert the high-pressure gas delivered by the second air pump 17 so that the gas can be evenly distributed to each blowing nozzle 14. The diverter chamber 13 usually adopts a design with a certain space and diverter structure inside, such as using multiple diverter plates or channels to evenly guide the gas to each blowing nozzle 14. This ensures that the pressure and flow of the gas blown out by the blowing nozzle 14 are uniform, thereby comprehensively and evenly blowing away the dust on the upper surface of the product. The blowing nozzles 14 are installed at the bottom of the diverter chamber 13. They are components that are in direct contact with the upper surface of the product and are responsible for blowing out the high-pressure gas and blowing off the dust on the upper surface of the product. The number and distribution of the blowing nozzles 14 are reasonably arranged according to the size and shape of the product to ensure that the entire upper surface of the product can be covered. The design of the blowing nozzle 14 is also similar to the blowing port 10 in the side sootblowing assembly. Factors such as the blowing speed, direction and area of ​​the gas need to be considered to improve the sootblowing efficiency.

[0034] The guide pipe 15 is a pipe connecting the diversion chamber 13 and the second air pump 17, which is responsible for transporting the high-pressure gas generated by the second air pump 17 to the diversion chamber 13. The guide pipe 15 is generally made of pressure-resistant and corrosion-resistant materials, and its diameter and length should be reasonably selected according to the output pressure of the second air pump 17 and the needs of the diversion chamber 13 to ensure that the gas can be smoothly transported to the diversion chamber 13 and the pressure loss is minimized. The connector 16 is used to connect the guide pipe 15 and the output pipe 18. It plays a role of connection and sealing to ensure that the gas will not leak during the transmission process. The design of the connector 16 must take into account the connection method and sealing requirements of the pipeline. Usually, sealing gaskets, threaded connections or quick connectors are used to ensure the firmness of the connection and the reliability of the seal.

[0035] The output pipe 18 is the output pipe 18 of the second air pump 17. It transports the high-pressure gas generated by the second air pump 17 to the guide pipe 15 and then into the diversion chamber 13 of the top sootblowing assembly. The material and diameter of the output pipe 18 should be selected according to the performance of the second air pump 17 and the requirements of the top sootblowing assembly to ensure that the gas can be transmitted smoothly. The second air pump 17 is the power source of the top sootblowing assembly. Its working principle is similar to that of the first air pump 8 in the side sootblowing assembly. The impeller is driven by the motor to rotate, and the air is sucked in and compressed to generate high-pressure gas. A second mounting base 19 is installed at the bottom of the second air pump 17. The second mounting base 19 is used to fix the second air pump 17 to ensure its stability and safety during operation. The design of the second mounting base 19 should take into account factors such as the weight, size and vibration of the second air pump 17. It should use strong materials and a reasonable structure to ensure that the second air pump 17 can work stably.

[0036] In summary, during operation, the conveyor body 1 is first started to start running and prepare to transport powder metallurgy formed products. At the same time, the first air pump 8 of the side soot blowing assembly and the second air pump 17 of the top soot blowing assembly are started.

[0037] The powder metallurgy formed product is placed on the conveyor belt body 1, and as the conveyor belt runs, the product starts to move forward.

[0038] When the product passes through the side soot blowing assembly, the high-pressure gas generated by the first air pump 8 is blown out through the blowing pipe 9 and the blowing port 10, blowing the sides of the product and blowing off the dust attached to the sides. The filters 11 on both sides of the housing 5 prevent external dust from entering the soot blowing assembly.

[0039] As the product continues to be transported forward, it reaches the bottom of the top sootblowing assembly. The high-pressure gas generated by the second air pump 17 enters the diversion chamber 13 through the output pipe 18 and the guide pipe 15. After being diverted by the diversion chamber 13, it is blown out evenly from the blowing nozzle 14, acting on the upper surface of the product to blow off the dust on the upper surface.

[0040] The product moves continuously on the conveyor belt body 1, and the side soot blowing components and the top soot blowing components continuously blow soot on the product, ensuring that dust in all parts of the product during the entire conveying process can be removed to the maximum extent, thereby improving the overall cleanliness of the product.

[0041] The products after soot blowing are output from the end of the conveyor belt and enter the subsequent processing steps or packaging links.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
