Abstract
Description
Technical Field
[0001] This utility model relates to the field of processing equipment for cold heading machines, and more particularly to a soft landing system for producing bolts using a cold heading machine. Background Technology
[0002] As automotive parts technology advances, the shapes and shapes of components become more complex, and their weight and size increase. Consequently, related quality requirements are gradually rising. In particular, the requirements for surface damage are extremely stringent, such as surface dents and scratches. These damages can lead to transmission noises after assembly, and in severe cases, may even prevent assembly altogether.
[0003] Traditional cold heading machines were not designed with the risk of damage from impacts on complex parts in mind. As a result, numerous impact damages inevitably occur during the movement of the formed parts from the mold exit to the material box.
[0004] Meanwhile, as the complexity of parts increases, it is required that parts be loaded in small quantities using plastic boxes. Because metal materials generate high temperatures during upsetting, typically between 120℃ and 180℃, ordinary plastic boxes are not heat-resistant and are easily burned. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a soft landing system for producing bolts in a cold heading machine.
[0006] The technical solution of this utility model is: a soft landing system for producing bolts in a cold heading machine, comprising: [the system is installed on the machine frame].
[0007] Material receiving track;
[0008] The first conveying unit is inclined, with its upper end connected to the receiving track and its lower end connected to the second conveying unit.
[0009] A second conveying unit passes sequentially through a cleaning chamber, a cooling chamber, and a drying chamber. The cleaning chamber contains cleaning fluid, and the drying chamber contains a hot air drying mechanism. A horizontal receiving section is located at the front end of the second conveying unit and connects to the first conveying unit. A discharge section is located at the rear end of the second conveying unit.
[0010] A receiving box is installed at the discharge section.
[0011] Furthermore, it also includes a rust-proof bin, which is located below the discharge section of the second conveying unit and between the receiving box. The material enters the rust-proof bin, and a third conveying unit is installed inside the rust-proof bin. The third conveying unit includes a third inclined conveying section and a third horizontal conveying section arranged sequentially upwards. An air knife is installed above the third horizontal conveying section, which is configured to cooperate with the receiving box. The rust-proof bin allows for certain treatment of the product, preventing rusting and other problems during subsequent processing. A V-shaped funnel-type interface with a manual valve is provided at the bottom of the trough for easy drainage.
[0012] Furthermore, the rust-preventive chamber is also connected to a secondary storage tank, and a suction pump is installed between the secondary storage tank and the rust-preventive chamber. When not soaking in rust-preventive oil, the rust-preventive oil in the rust-preventive chamber can be placed in the secondary storage tank, and then pumped back to the rust-preventive chamber when needed, which can achieve different types of processing.
[0013] Furthermore, the first, second, and third conveying units are all circulating conveying systems. Chain drive is generally sufficient, with a storage compartment between the two chains. The transmission system uses a brake motor to drive the conveyor chain plates (stainless steel mesh belt) to achieve cyclic rotation. The chain spacing is 110mm (internal effective distance). Parts are supported between the chain plates via spindles. Baffles are installed on the conveyor chain plates to limit part displacement. The conveying device is equipped with a torque limiter to prevent equipment damage caused by parts jamming the track. Transmission speed: 0.1-0.6m / min. The brake motor drive uses a frequency converter to control the linear speed, which can be adjusted appropriately according to the surface cleanliness and temperature of the parts.
[0014] Furthermore, a receiving and guiding platform is installed on the frame. This platform allows for the temporary storage of products, and a suitable receiving box can also be selected and installed at this location.
[0015] All conveying units are driven by motors to circulate conveyor belts. The conveyor belts are arranged in a closed loop, and their shape can be adjusted according to actual needs.
[0016] Furthermore, the conveyor belts in the cleaning and cooling chambers are arranged in an inverted trapezoidal shape. The two sides are inclined, while the middle is horizontal. This arrangement ensures smooth cleaning and cooling processes.
[0017] Furthermore, an air knife is installed between the cooling chamber and the drying chamber. The air knife can blow away any residual water after cleaning, preventing water stains from forming during the drying stage.
[0018] Furthermore, at least two air knives are provided. They can be arranged in parallel or vertically to ensure effective drying. The cooling chamber has an air pressure of 0.5-0.7 MPa and is equipped with a 100L air tank. The drying chamber is externally connected to a 3KW vortex air pump to provide the air source. The temperature is set at 70-120℃ and is equipped with an 8KW heating element.
[0019] Furthermore, the cleaning chamber is equipped with ultrasonic transducers. The cleaning chamber is used for ultrasonic cleaning, and the ultrasonic system is equipped with 36 ultrasonic transducers, with a total ultrasonic power of 1800W and a frequency of 28kHz. The ultrasonic system features adjustable power and a power display function.
[0020] Furthermore, the receiving track is arc-shaped and slopes downwards. This arc-shaped receiving track effectively prevents damage caused by bolts falling off and colliding with the track.
[0021] The beneficial technical effects of this invention are as follows: By utilizing the properties of liquid, the parts are buffered and energy absorbed during transfer, thus preventing impact damage. The properties of water are used to cool the parts, and simultaneously, ultrasonic waves are used for cleaning and rust prevention. This allows for the transfer of cold-headed parts to the material box at room temperature without damage, all through a single mechanism. This improves product stability and provides a reliable guarantee for subsequent processing. Attached Figure Description
