Description

Technical Field

[0001] This application relates to the technical field of oil fume purification, and in particular to an oil fume-proof structure for a heading machine. Background Technology

[0002] Heading machines are specialized equipment primarily used for the mass production of fasteners such as nuts and bolts in industrial applications. Utilizing the principle of stamping, they shape metal materials into the desired form under the action of a die. Equipped with an automated control system, they can automatically complete feeding, heading, and unloading, enabling mass production. The efficient screw head processing capabilities of heading machines play a vital role in driving industrial production processes.

[0003] Currently, during the operation of a heading machine, intense friction occurs between the die and the metal billet. During cold heading, the die and billet are in close contact, generating significant frictional force during relative movement. To reduce this friction and ensure smooth processing, a lubricant needs to be added between the die and the billet. The lubricant forms a lubricating film on the metal surface, effectively reducing direct contact between the die and the billet, minimizing friction and wear, extending the die's lifespan, and also contributing to improved workpiece forming quality. In actual production, the large amount of heat generated during cold heading causes a rapid increase in temperature at the contact area between the die and the billet.

[0004] In high-temperature environments, lubricants undergo thermal decomposition. The lubricant, originally intended for lubrication, has its chemical structure disrupted under high temperatures, decomposing into volatile organic compounds and aerosols. Simultaneously, cold heading processes generate metal debris. These decomposition products mix with the metal debris to form oil fumes. Ultimately, this results in large amounts of oil fumes spreading irregularly throughout the workshop, rapidly deteriorating air quality, adhering to equipment surfaces, accelerating equipment aging and corrosion, and causing serious health hazards to employees who inhale the oily fumes over extended periods. Utility Model Content

[0005] In view of the shortcomings of the existing technology, one of the objectives of this utility model is to provide an oil fume-proof structure for a heading machine.

[0006] This application provides an oil fume prevention structure for a heading machine, which adopts the following technical solution:

[0007] An oil fume prevention structure for a heading machine includes a housing, an air intake component for extracting oil fumes, a shielding component for blocking oil fumes, and an exhaust pipe for discharging oil fumes. The housing has an inlet for introducing blanks, an outlet for discharging finished products, and an air intake for cooperating with the air intake component to draw air. One end of the air intake component is connected to the air intake and the housing, and the other end is connected to the exhaust pipe. The shielding component covers the outlet.

[0008] By adopting the above technical solution, the billet is introduced from the feed inlet, ensuring that the billet can be accurately and efficiently input into the processing area. When the heading machine is operating, the friction between the mold and the workpiece generates a large amount of heat and a large amount of debris. When the lubricant lubricates the mold and the billet, it evaporates, generating a mixture of oil fumes and debris. One end of the suction component extracts the oil fumes present inside the outer shell and the shielding component, while the other end transports the oil fumes to the exhaust pipe, and finally discharges them to the exhaust gas treatment device outside the workshop. The oil fume prevention structure of this heading machine can not only discharge the mixture of oil fumes and debris, but also effectively intercept the oil fumes through the outer shell and the shielding component, preventing the oil fumes from spreading into the workshop, reducing the risk of equipment failure due to oil fume corrosion, extending the service life of the equipment, and reducing the potential health hazards of oil fumes to workers, thus ensuring a clean and safe production environment.

[0009] Preferably, the shielding assembly includes a shield for shielding oil fumes and a guide curtain for guiding finished products, wherein the bottom of the shield is connected to the top of the guide curtain.

[0010] By adopting the above technical solutions, the shield effectively blocks the oil fumes generated during the operation of the heading machine and spreading towards the discharge port and the air intake port. The guide curtain provides a smooth sliding path for the finished products, preventing the finished products from splashing outward due to collisions or deviations during the discharge process. The shield and the guide curtain are connected and work together to ensure the stability and efficiency of the finished product discharge process while effectively blocking the oil fumes.

[0011] Preferably, the top of the shield is connected to the outer shell via a hinge structure, and the shield is provided with a handle for rotating the shield.

[0012] By adopting the above technical solution, the angle of the shield can be flexibly adjusted by the handle during equipment operation, so as to observe the internal working status at any time, identify and solve problems in a timely manner. When working normally, closing the shield can effectively block foreign objects and fumes, prevent accidental contact by personnel, and ensure operational safety.

[0013] Preferably, a storage hopper for storing finished products is provided below the guide curtain, and a quality inspection hopper for collecting finished products is placed on top of the storage hopper, the opening of the quality inspection hopper being adapted to the opening at the bottom of the guide curtain.

[0014] By adopting the above technical solutions, the finished products are prevented from scattering due to lack of guidance during discharge. The quality inspection hopper is set up separately, which makes it convenient for operators to quickly conduct quality sampling inspections during the finished product collection stage. The storage hopper is used to store the finished products that have passed the quality inspection, realizing the orderly classification and storage of finished products and improving the systematicness and efficiency of the heading machine shell in the processing of finished products.

[0015] Preferably, the air intake assembly includes a first air intake pipe, a second air intake pipe, and a fan for air intake. The air inlet of the first air intake pipe is connected to the air intake port, and the air outlet of the first air intake pipe is connected to the fan. The air inlet of the second air intake pipe is located inside the housing, and the air outlet of the second air intake pipe is connected to the fan. The fan is connected to the exhaust pipe.

[0016] By adopting the above technical solution, the first suction pipe is connected to the suction port, which can quickly suck in the oil fumes in the shielding component, while the second suction pipe can directly collect oil fumes from near the source of the oil fumes, improving the efficiency of oil fume extraction and ensuring that the amount of oil and fumes mixed in the shell and shielding component is reduced to the greatest extent. At the same time, the fan is connected to the first suction pipe, the second suction pipe and the exhaust pipe, realizing the smooth discharge of oil fumes and avoiding the accumulation of oil fumes in the shell, thereby reducing the pollution of oil fumes in the workshop.

[0017] Preferably, the outer shell is provided with a chip receiving tray for holding raw material chips, and the chip receiving tray is located below the feed inlet.

[0018] By adopting the above technical solution, the chip receiving tray can collect the chips generated by the billet from the feed port, preventing them from scattering everywhere, keeping the workshop floor and equipment area clean, reducing the frequency of cleaning, optimizing the working environment, and the collected chips are convenient for subsequent unified recycling and processing.

[0019] Preferably, a discharge chute for assisting discharge is provided on one side of the discharge port, and discharge baffles are connected to both sides of the discharge chute.

[0020] By adopting the above technical solutions, the discharge chute can reduce the friction of the finished product during discharge by means of its smooth surface and inclined angle, so that the finished product can slide stably away from the discharge port, thereby improving the discharge efficiency. The discharge baffle can effectively prevent the finished product from deviating from the chute due to vibration and collision during the discharge process, ensuring that the finished product is discharged smoothly.

[0021] Preferably, the outer casing has an inspection port for quality inspection, and the outer casing has an inspection door at the inspection port, the inspection door being hinged to the outer casing.

[0022] By adopting the above technical solution, when a problem occurs with the heading machine, the hinged inspection door can be opened directly, and the interior can be observed closely through the inspection port for inspection and maintenance.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. This oil fume prevention mechanism can block and collect the oil fumes generated by the heading machine, thus preventing the oil fumes from spreading outward. At the same time, the air intake component can suck up the blocked oil fumes and discharge them to the external exhaust gas treatment device, reducing the corrosion of the equipment caused by oil fume erosion, extending the service life of the equipment, and reducing the harm of oil fumes to the health of workers, ensuring the cleanliness and safety of the production environment.

[0025] 2. The shield can effectively block the oil fumes generated during the operation of the heading machine and spread towards the discharge port. The guide curtain provides a smooth sliding path for the finished products, preventing them from splashing outwards due to collisions or deviations during the discharge process. The shield and the guide curtain are connected and work together to effectively block oil fumes while ensuring the stability and efficiency of the finished product discharge process.

[0026] 3. During equipment operation, the angle of the shield can be flexibly adjusted by the handle to observe the internal working status at any time, and to promptly identify and resolve problems. When operating normally, closing the shield can effectively block foreign objects and fumes, prevent accidental contact by personnel, and ensure operational safety. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0031] This application discloses an oil fume prevention structure for a heading machine.

[0032] Reference Figure 1 and Figure 2An oil fume prevention structure for a heading machine includes a housing 1, a shielding component 3, an air intake component 2 for extracting oil fumes, and an exhaust pipe 4 for discharging oil fumes. The housing 1 is mounted on the outer periphery of the heading machine to block and collect the oil fumes generated during the heading machine's operation. The housing 1 has an inlet 5 for feeding materials and an outlet 6 for discharging finished products. The feeding mechanism is sealed to the housing 1 through the inlet 5. The outlet 6 is open for easy material unloading. The shielding component 3 covers the outlet 6 to block and collect a small portion of the oil fumes escaping from the outlet 6. The air intake end of the air intake component 2 extends into the shielding component 3 and the housing 1, respectively, and its outlet end is connected to the exhaust pipe 4. The air intake component 2 draws in the oil fumes from the housing 1 and the shielding component 3 and discharges them to an external waste gas treatment device through the exhaust pipe 4.

[0033] The oil fume prevention structure of this heading machine is mainly used to block the oil fumes generated by the heading machine. A small portion of the oil fumes escaping from the discharge port 6 is blocked and collected by the shielding component 3 to prevent the oil fumes from spreading outward. At the same time, the suction component 2 and the exhaust pipe 4 work together to suck up the blocked oil fumes and discharge them to the external exhaust gas treatment device, reducing the corrosion of the equipment caused by oil fume erosion, extending the service life of the equipment, reducing the harm of oil fumes to the health of workers, and ensuring the cleanliness and safety of the production environment.

[0034] The feed inlet 5 is located on the side of the outer casing 1, near the top. The feed inlet 5 is rectangular in shape, allowing for a close fit with the feeding mechanism. The size of the feed inlet 5 is designed according to the size of the feeding mechanism. This ensures that the billet can enter the feed inlet 5 accurately and smoothly when the feeding mechanism is conveying the billet. The discharge outlet 6 is located near the bottom of the outer casing 1. The discharge outlet 6 is also rectangular. After the finished product is processed, the open discharge outlet 6 prevents the finished product from being squeezed or collided during the discharge process, thus avoiding deformation or damage. This ensures that the finished product can be discharged smoothly and intact from the discharge outlet 6.

[0035] The shielding assembly 3 includes a shielding cover 31 and a guide curtain 32. The shielding cover 31 is wedge-shaped. One side of the shielding cover 31, which is not adjacent to the ground, is open, while the other side, facing away from the slope, rests on the outer shell 1 and is also open. The shielding cover 31 covers the discharge port 6. The top of the shielding cover 31 is hinged to the outer shell 1. The shielding cover 31 effectively prevents the oil fumes from spreading outward. The bottom of the shielding cover 31 is riveted to the top of the guide curtain 32. The guide curtain 32 is made of rubber. Utilizing the good elasticity and flexibility of rubber, when the finished product slides down the guide curtain 32, its elastic properties can effectively buffer the impact between the finished product and the guide curtain 32, preventing the finished product from being damaged by rigid collisions during the descent. While generating noise, it ensures that the finished products can slide smoothly down the predetermined direction of the guide curtain 32, avoiding product damage caused by splashing. Under the joint action of the shield 31 and the guide curtain 32, the oil fumes are effectively isolated in a relatively closed space and finally efficiently collected by the suction component 2 and discharged through the exhaust pipe 4, which greatly reduces the pollution of oil fumes to the workshop environment and creates a clean and healthy working environment for operators. At the same time, a handle 33 is horizontally installed on the outer surface of the shield 31 near the top edge. The two ends of the handle 33 are tightly connected to the shield 31 by strong bolts, and the operator can easily hold the handle 33 to open and close the shield 31.

[0036] The suction assembly 2 includes a first suction pipe 21 and a fan 23. The suction port is located near the discharge port 6. The air inlet of the first suction pipe 21 is connected to the air inlet on the outer casing 1, and the air outlet of the first suction pipe 21 is connected to the fan 23. When the finished product is discharged from the discharge port 6, a small amount of exhaust gas escapes from the discharge port 6, ensuring that the oil fumes in the area near the discharge port 6 can smoothly enter the first suction pipe 21. The fan 23 draws in the oil fumes in the shielding assembly 3 and quickly transports the sucked oil fumes to the fan 23.

[0037] Furthermore, the suction assembly 2 also includes a second suction duct 22, the inlet of which is directly installed inside the outer casing 1 near the source of the oil fume. During the operation of the heading machine, the raw material processing area is the main source of oil fumes. The inlet of the second suction duct 22 is located near this area, enabling it to capture the newly generated oil fumes immediately. The outlet of the second suction duct 22 is also closely connected to the fan 23, allowing the oil fumes collected from the inside to quickly converge at the fan 23.

[0038] As the core power source of the entire suction assembly 2, the fan 23 not only draws in exhaust gas from the two suction pipes, but also pressurizes the collected exhaust gas and delivers it to the exhaust pipe 4. The exhaust pipe 4 is responsible for guiding the exhaust gas to a dedicated exhaust gas treatment device. Through this design, the suction assembly 2 can comprehensively and efficiently suck in the oil fumes inside the outer casing 1 and those discharged from the outlet 6, delivering the oil fumes to the exhaust gas treatment device in a timely manner. This effectively prevents oil fumes from adhering to the equipment surface, reducing the risk of equipment failure due to oil fume corrosion, extending the equipment's service life, creating a clean production environment in the workshop, and protecting the health of the operators.

[0039] A chip collection tray 10 is installed at the feed inlet 5. The chip collection tray 10 is located directly below the feeding mechanism. When the heading machine is operating, the billet will be squeezed and rubbed against the feeding mechanism to generate chips. The chip collection tray 10 can collect and hold the falling chips.

[0040] A discharge chute 11 is installed at the discharge port 6. The discharge port 6 is connected to the inclined discharge chute 11. After the finished product completes the processing, it can slide down quickly along the discharge chute 11. Vertical discharge baffles 12 are connected to both sides of the discharge chute 11. The overall cross-section of the discharge chute 11 and the discharge baffles 12 is U-shaped. The U-shaped structure enables the finished product to slide down quickly while reducing the deviation of the finished product from the discharge chute 11 due to vibration and collision during the discharge process, thus ensuring the smooth discharge of the finished product.

[0041] The storage hopper is placed below the guide curtain 32, and the quality inspection hopper 9 is placed on top of the storage hopper 8. The opening size of the quality inspection hopper 9 is precisely matched with the bottom opening of the guide curtain 32. When the heading machine discharges material, the quality inspection hopper 9 is placed below the guide curtain 32. After collecting the finished products, the operator inspects them. Finished products that meet the quality inspection standards can be poured into the storage hopper 8. This allows the operator to quickly conduct quality sampling inspections during the finished product collection stage, reducing the probability of defective products flowing into subsequent processes.

[0042] An inspection port 13 is opened at the top of the outer casing 1, ensuring that the inspection port 13 is close to the critical components inside the heading machine that are prone to failure. The inspection door 14 installed at the inspection port 13 is hinged to the outer casing 1, which allows maintenance personnel to quickly and directly access the parts that need maintenance during maintenance. This not only ensures the airtightness of the outer casing 1 of the heading machine, ensuring that pollutants such as oil fumes and dust inside the heading machine will not leak from the inspection port 13 during normal operation, but also provides convenience for the inspection and maintenance of internal equipment, reduces equipment maintenance costs and downtime, and ensures the continuity and stability of production.

[0043] The implementation principle of this application embodiment is as follows: During the assembly process of the oil fume prevention structure of the heading machine, the top of the guide curtain 32 is first riveted to the bottom of the shield 31. The top of the shield 31 is hinged to the outer shell 1 through a hinge to ensure that the shielding component 3 can cover the discharge port 6 and the air intake. The chip receiving plate 10 is welded below the feed port 5, and the discharge slide 11 is welded below the discharge port 6. Then, the oil fume prevention structure of the heading machine is installed on the heading machine. The air intake end of the first air intake pipe 21 is connected to the air intake 7. The air intake end of the second air intake pipe 22 is installed inside the outer shell 1 near the position where oil fumes are generated. The air outlet ends of the first air intake pipe 21 and the second air intake pipe 22 are tightly connected to the fan 23. The air outlet of the fan 23 is connected to the exhaust pipe 4, which can be sealed with sealant. Finally, the storage hopper 8 is abutted against the outer shell 1 so that the opening of the quality inspection hopper 9 is adapted to the bottom end of the guide curtain 32.

[0044] During operation, the oil fume prevention structure of the heading machine places the billet into the feeding mechanism, and the billet enters the heading machine. As the heading machine operates, the high-speed friction between the mold and the billet generates a large amount of oil fume and debris. The blower 23 is activated, and the first suction pipe 21 draws air from the suction port to the shielding component 3, while the second suction pipe 22 draws air from inside the outer casing 1 near the mold. The air mixed with debris and oil fume is gathered to the blower 23, pressurized by the blower 23, and then discharged through the exhaust pipe 4 to the exhaust gas treatment device outside the workshop. The guide curtain 32 guides the finished product to slide smoothly down. The finished product slides quickly down the discharge chute 11 and enters the quality inspection hopper 9 above the storage hopper 8, facilitating subsequent quality inspection. Below the feed inlet 5, the chip receiving tray 10 continuously collects debris generated during billet processing, preventing debris from scattering and affecting equipment operation and the workshop environment. In case of problems with the heading machine, maintenance can be performed through the inspection port 13.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
