Description

Technical Field

[0001] This invention relates to the field of press-fitting technology for automotive fuse housings, specifically to a special press-fitting equipment and process for hot-pressing inserts into automotive fuse housings. Background Technology

[0002] As the automotive industry moves towards lightweight and high-reliability designs, automotive fuses, as critical electrical protection components, face higher demands on housing structural strength, insert connection stability, and production efficiency. Fuse housings are mostly made of engineering plastics such as PA66, requiring the insertion of metal inserts to achieve electrical conduction and mechanical fixation. The quality of insert insertion directly affects the fuse's service life and safety performance. Currently, the mainstream method for insert insertion in the industry is thermoforming, where a metal ring is pressed into the plastic component.

[0003] However, existing press-fitting equipment has low efficiency for manual feeding, is prone to mechanical damage, and has large positioning deviations in plastic parts, affecting the continuity of press-fitting. Summary of the Invention

[0004] The purpose of this invention is to provide a special pressing equipment and pressing process for hot-pressing inserts into automotive fuse housings, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a special pressing device for hot-pressing inserts into automotive fuse housings, comprising a vibratory plate and an internal plate. Both sides of the vibratory plate are equipped with a feeding assembly for auxiliary feeding. The feeding assembly includes a feeding frame, a servo motor, a lead screw, a feeding plate, and a sliding plate. A servo motor is installed at one end of the feeding frame, and a lead screw is provided at the output end of the servo motor. The feeding plate is threaded onto the outer surface of the lead screw, and a sliding plate is slidably disposed inside the feeding plate. A feeding frame is installed above the feeding frame, and the internal plate is slidably disposed on the inner surface of the feeding frame. A pressing assembly for auxiliary pressing is installed above the feeding frame, and the pressing assembly includes a vertical plate, a hydraulic rod, a connecting plate, and a pressing plate. A hydraulic rod is provided on one side of the bottom of the vertical plate, and a connecting plate is installed at the output end of the hydraulic rod. A pressing plate is provided at the bottom of the connecting plate.

[0006] Furthermore, the internal threads of the built-in plate are fitted with threaded rods, and both the built-in plate and the threaded rods are provided in two sets.

[0007] Furthermore, a hydraulic rod 2 is provided between the two sets of built-in plates, and a push plate is installed at the output end of the hydraulic rod 2. The built-in plates have built-in holes inside.

[0008] Furthermore, a discharge port is provided on the side of the feeding frame away from the servo motor, and a collection frame is installed below the discharge port.

[0009] Furthermore, a vibration motor is provided at the bottom of the vibratory feeder, and vibration springs are installed on both sides of the bottom of the vibratory feeder.

[0010] Furthermore, a base is installed at the bottom of the vibration spring, and a base is provided at the bottom of the base.

[0011] Furthermore, the vibratory feeder has adjusting screws threaded on both sides inside, and an adjusting plate is rotatably mounted at the bottom of the adjusting screws.

[0012] Furthermore, the adjusting plate is slidably disposed inside the vibratory feeder, and the feeding assembly is provided in two sets.

[0013] Furthermore, the pressing process of the special pressing equipment for hot-pressing inserts into automotive fuse housings is as follows: The plastic parts to be pressed are pre-placed into the feeding frames of the two side feeding components. The metal rings are placed into the vibratory feeder. After starting the equipment, the vibration motor at the bottom of the vibratory feeder begins to work, cooperating with the vibration spring to drive the vibratory feeder to vibrate. Simultaneously, the height of the adjusting plate can be adjusted by adjusting the adjusting screw inside the vibratory feeder to avoid overlapping of the metal rings during transport. The power generated by the vibration, combined with the inclined design of the feeding frame, smoothly transports the metal rings between the two sets of internal plates. Subsequently, the hydraulic rods between the internal plates drive the push plate to move, uniformly and centrally aligning the metal rings with varying spacing, ensuring precise alignment of the metal rings with the internal holes on the internal plates. At the same time, the feeding components... The servo motor in the middle starts, driving the lead screw to rotate. Under the guidance of the slide plate, it moves the feeding plate horizontally, pushing the plastic parts in the feeding frame to the area directly below the built-in hole. At this time, the sensor grating is triggered, and the feeding plate stops moving. Finally, the hydraulic rod in the pressing assembly extends, driving the connecting plate and the bottom pressing plate downward. The pressing plate is equipped with heating wires to facilitate hot pressing. The pressure of the pressing plate accurately presses the metal ring in the built-in hole into the plastic parts below, completing one pressing process. After pressing, the plastic parts can fall into the collection box below through the discharge port on the side of the feeding frame away from the servo motor, realizing centralized recycling of materials. In addition, the distance between the two sets of built-in plates can be adjusted by rotating the threaded rod according to the specifications of the metal ring, improving the adaptability of the equipment.

[0014] This invention provides a dedicated press-fitting device and process for hot-pressing inserts into automotive fuse housings, which has the following advantages: 1. This invention achieves automated horizontal pushing of plastic parts by using symmetrically arranged feeding components on both sides, combined with a servo motor and lead screw transmission structure. This eliminates the need for manual feeding, effectively avoiding the risk of mechanical damage that may be encountered during manual operation. At the same time, the precise positioning design of the sensor grating ensures that the plastic parts are accurately delivered to the designated pressing area and then automatically stop, further improving the standardization and reliability of the feeding process and significantly increasing overall production efficiency.

[0015] 2. This invention utilizes a vibratory conveying structure with a vibrating plate and a vibrating spring, combined with an inclined design of the feeding frame, to achieve stable and rapid conveying of metal rings. The hydraulic rods and push plate structure between the two sets of built-in plates can uniformly and centrally organize metal rings with varying spacing, ensuring precise alignment of the metal rings with the built-in holes, laying the foundation for subsequent pressing. In addition, the pressing plate driven by the hydraulic rod applies stable pressure, enabling the metal rings to be accurately and firmly pressed into the plastic parts, effectively avoiding pressing failures caused by positioning deviations.

[0016] 3. The built-in plate spacing of this invention can be flexibly adjusted by rotating the threaded rod clockwise or counterclockwise, and the plate height can be adjusted by adjusting the screw. It can adapt to the conveying and pressing needs of metal rings of different specifications, improving the versatility of the equipment. At the same time, the discharge port opened on one side of the feeding frame and the collection frame below can be used to collect unqualified or excess plastic parts, which is convenient for subsequent material sorting and recycling, and optimizes the integrity of the production process.

[0019] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0020] like Figures 1-5As shown, a special pressing device for hot-pressing inserts into automotive fuse housings includes a vibratory feeder 1, a base 2, a feeding assembly 3, a feeding frame 301, a servo motor 302, a lead screw 303, a feeding plate 304, a sliding plate 305, a discharge port 4, a pressing assembly 5, a vertical plate 501, a hydraulic rod 1 502, a connecting plate 503, a pressing plate 504, a feeding frame 6, an internal plate 7, a threaded rod 8, a vibratory motor 9, a vibratory spring 10, a base 11, a collecting frame 12, an adjusting plate 13, an adjusting screw 14, a hydraulic rod 2 15, a push plate 16, and an internal hole 17. Feeding assemblies 3 for auxiliary feeding are installed on both sides of the vibratory feeder 1, and each feeding assembly 3 includes a feeding frame 301, a servo motor 302, a lead screw 303, a feeding plate 304, and a sliding plate 305. The vibratory feeder 1 has adjusting screws 14 threaded on both sides inside, and an adjusting plate 13 is rotatably mounted at the bottom of the adjusting screws 14. The adjusting plate 13 is slidably mounted inside the vibratory feeder 1. Two sets of feeding components 3 are provided. The height of the adjusting plate 13 is adjustable via the adjusting screws 14, preventing overlapping during metal ring conveying. A discharge port 4 is opened on the side of the feeding frame 301 away from the servo motor 302, and a collection frame 12 is installed below the discharge port 4. A vibratory motor 9 is installed at the bottom of the vibratory feeder 1, and vibration springs 10 are installed on both sides of the bottom of the vibratory feeder 1. A base 2 is installed at the bottom of the vibration springs 10, and a base 11 is installed at the bottom of the base 2. The design of the vibratory motor 9 and the vibration springs 10 enables the vibratory feeder 1 to vibrate. The vibrating disc 1 generates vibration that vibrates and transfers a metal ring placed inside the vibrating disc 1 between two sets of built-in plates 7. The inclined design of the feeding frame 6 facilitates the rapid transfer of the metal ring between the two sets of built-in plates 7 through vibration and its own gravity. The distance between the two sets of built-in plates 7 can be adjusted by rotating the drive screw rod 8 clockwise or counterclockwise, which is beneficial for guiding and fitting the metal ring. A servo motor 302 is installed at one end of the loading frame 301, and a lead screw 303 is provided at the output end of the servo motor 302. A loading plate 304 is threaded onto the outer surface of the lead screw 303, and a sliding plate 305 is slidably arranged inside the loading plate 304. A feeding frame 6 is installed above the loading frame 301, and the built-in plates 7 are slidably arranged on the inner surface of the feeding frame 6. The loading frame 301 is pre-loaded with the plastic parts to be pressed. The servo motor 302 drives the lead screw 303 to rotate. Through the rotation of the lead screw 303 and the guiding design of the slide plate 305, the loading plate 304 moves horizontally relative to the feeding frame 6, thus horizontally pushing the plastic parts placed in the loading frame 301, avoiding manual feeding and reducing safety hazards. A sensor grating is also provided, which stops the plastic parts when they reach the area below the feeding frame 6, i.e., below the internal hole 17. A pressing assembly 5 for auxiliary pressing is installed above the feeding frame 6. The pressing assembly 5 includes a vertical plate 501, a hydraulic rod 502, a connecting plate 503, and a pressing plate 504. The hydraulic rod 502 is located on one side of the bottom of the vertical plate 501.Furthermore, a connecting plate 503 is installed at the output end of the hydraulic rod 502, and a pressing plate 504 is provided at the bottom of the connecting plate 503. The design of the hydraulic rod 502 allows the connecting plate 503 and the pressing plate 504 to move downwards. The movement of the pressing plate 504 allows the metal ring located in the internal hole 17 to be pressed into the plastic part, enabling convenient pressing processing.

[0021] like Figure 1 and Figure 5 As shown, the built-in plate 7 has a threaded rod 8 installed inside its internal thread, and both the built-in plate 7 and the threaded rod 8 are provided in two sets. A hydraulic rod 15 is provided between the two sets of built-in plates 7, and a push plate 16 is installed at the output end of the hydraulic rod 15. The built-in plate 7 has an internal hole 17. The feeding frame 6 is not connected to the vibrating plate 1. When the metal ring enters between the two sets of built-in plates 7, the design of the hydraulic rod 15 can drive the push plate 16 to move, thereby concentrating the metal rings that may have different spacings. This ensures that the metal rings are neatly arranged and are exactly in the internal hole 17, which is convenient for pressing the metal rings into the plastic parts later.

[0022] In summary, the specialized press-fitting equipment and process for hot-pressing the insert into the automotive fuse housing firstly... Figures 1-5The structure shown in the diagram requires material preparation during use. The plastic parts to be pressed are pre-placed into the feeding frames 301 of the two side feeding components 3. The metal rings are then placed into the vibratory feeder 1. After starting the equipment, the vibration motor 9 at the bottom of the vibratory feeder 1 begins operation, working in conjunction with the vibration spring 10 to drive the vibratory feeder 1 to vibrate. Simultaneously, the height of the adjusting plate 13 can be adjusted by adjusting the adjusting screw 14 inside the vibratory feeder 1 to prevent the metal rings from overlapping during transport. The power generated by the vibration, combined with the inclined design of the feeding frame 6, smoothly transports the metal rings between the two sets of internal plates 7. Subsequently, the hydraulic rod 15 between the internal plates 7 drives the push plate 16 to move, uniformly and centrally aligning the metal rings with varying spacing, ensuring precise alignment of the metal rings with the internal holes 17 on the internal plates 7. At the same time, the servo motor 302 in the feeding component 3 starts, driving the lead screw 303 to rotate, and the metal rings move along the slide plate. Guided by 305, the feeding plate 304 moves horizontally, pushing the plastic parts in the feeding frame 301 to the area directly below the built-in hole 17. At this time, the sensor grating is triggered, and the feeding plate 304 stops moving. Finally, the hydraulic rod 502 in the pressing assembly 5 extends, driving the connecting plate 503 and the bottom pressing plate 504 to move downward. The pressing plate 504 is equipped with a heating wire to facilitate hot pressing. The pressure of the pressing plate 504 accurately presses the metal ring in the built-in hole 17 into the plastic parts below, completing one pressing process. After pressing, the plastic parts can fall into the collection frame 12 below through the discharge port 4 on the side of the feeding frame 301 away from the servo motor 302, realizing centralized recycling of materials. In addition, the distance between the two sets of built-in plates 7 can be adjusted by rotating the threaded rod 8 according to the specifications of the metal ring, improving the adaptability of the equipment.
