Description

Technical Field

[0001] This invention relates to the field of stamping equipment technology, specifically to a stamping equipment for producing copper needles for automotive gaskets. Background Technology

[0002] Automotive gaskets are key sealing elements in powertrain systems such as engines and transmissions. They are mainly used to fill gaps between component mating surfaces, prevent leakage of media such as engine oil, coolant, and fuel, and block the intrusion of external impurities, ensuring the stable operation and service life of the powertrain system. Modern gaskets generally integrate copper pins for wiring, which, while achieving electrical connection and heat conduction, adapt to the trend of intelligent and electrified automotive development, becoming an indispensable and important structure for high-performance gaskets. The forming of copper pins relies on a special stamping device to stamp copper strips. The performance of the equipment directly determines the dimensional accuracy, surface quality, and consistency of the copper pins, thus affecting the overall performance of the automotive gasket.

[0003] However, in actual production, the copper pin stamping device for wiring is prone to problems. During storage and transportation, copper strips are easily contaminated with impurities such as copper powder and dust. During stamping, these impurities are pressed into the surface of the copper pins, forming defects such as pits and scratches, which affect the surface quality and structural integrity of the copper pins. At the same time, traditional oiling often uses a concentrated dripping method, which cannot evenly cover the contact surface between the copper strip and the mold, resulting in poor lubrication. This not only aggravates the wear of the punch and the mold and shortens the equipment life, but also easily leads to burrs and deformation of the copper pins. In addition, qualified and unqualified products are directly mixed and fall off after stamping. It is impossible to identify quality defects such as size and surface in real time online. It can only rely on manual sorting, which is labor-intensive and has low sorting efficiency, thus restricting the overall production efficiency. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-9 This invention provides a technical solution: a stamping device for producing copper needles for automotive sealing gaskets, comprising a stamping machine body 1, a stamping structure 2 mounted on the stamping machine body 1, an oiling structure 3 mounted on the stamping machine body 1, a cleaning structure 5 mounted on the stamping machine body 1, and a detection structure 7 mounted on the stamping machine body 1; the stamping structure 2 includes a slider 201 slidably connected to the stamping machine body 1 and an upper die 202 mounted on the slider 201, a lower die 203 mounted on the stamping machine body 1, and a mounting device 7 mounted on the slider 201. Plate 205, mounting plate 205 is provided with inclined groove 206, oiling structure 3 includes fixed rod 301 fixedly connected to the stamping machine body 1 and slide rod 302 slidably connected to fixed rod 301, drive shaft 303 is rotatably connected to slide rod 302, drive shaft 303 is in rolling cooperation with inclined groove 206, connecting seat 304 is fixedly connected to slide rod 302, mounting seat 305 is detachably connected to connecting seat 304, connecting shaft 306 is rotatably connected to mounting seat 305, and oiling roller 307 is fixedly connected to connecting shaft 306.

[0022] A crank drive assembly 204 is installed on the press body 1. The slider 201 is driven to slide by the crank drive assembly 204. A rack 309 is installed on the press body 1. A gear 308 is fixedly connected to the connecting shaft 306. The gear 308 meshes with the rack 309. An oil supply structure 4 is provided on the press body 1. The oil supply structure 4 includes an oil storage tank 401 installed on the press body 1 and a first connecting pipe 402 installed on the oil storage tank 401. An oil pump 403 is installed on the press body 1. The other end of the first connecting pipe 402 is installed on the inlet of the oil pump 403. A second connecting pipe 404 is fixedly connected between the outlet of the oil pump 403 and the connecting seat 304.

[0023] In practical use, the crank drive assembly 204 uses a motor to drive the crank to rotate, converting the rotational motion into a vertical reciprocating motion of the connecting rod driving the slider 201, providing stable and continuous power for stamping. While the slider 201 moves up and down, it simultaneously drives the mounting plate 205 and the inclined groove 206 to move synchronously. The inclined groove 206 rolls with the drive shaft 303, driving the slide rod 302 to slide horizontally back and forth along the fixed rod 301. The rollers on the fixed rod 301 reduce the friction of the slide rod 302. The slide rod 302 drives the mounting base 305, the connecting shaft 306, and the connecting seat 304 through the connecting seat 304. The oiling roller 307 moves synchronously, and the gear 308 on the connecting shaft 306 meshes with the rack 309 on the press body 1, so that the oiling roller 307 rotates simultaneously during the movement. The oil pump 403 delivers the lubricating oil in the oil storage tank 401 to the oiling roller 307 through the first connecting pipe 402 and the second connecting pipe 404, so that the lubricating oil is evenly attached to the surface of the oiling roller 307 and evenly coated on the surface of the copper strip as it rolls, avoiding the problem of local concentrated oiling and poor lubrication effect, effectively reducing the wear between the mold and the workpiece, and improving the smoothness of the copper needle forming surface.

[0024] Mounting base 305 is mounted on connecting base 304 via mounting structure 8. Mounting structure 8 includes mounting block 801 fixedly connected to mounting base 305 and mounting shaft 802 rotatably connected to connecting base 304. Mounting block 801 is slidably connected to connecting base 304. A baffle 803 is fixedly connected to mounting shaft 802, which abuts and limits the mounting block 801. A second torsion spring 804 is fixedly connected between mounting shaft 802 and connecting base 304.

[0025] In practical use, when disassembling, rotate the baffle 803 to deform the second torsion spring 804. The baffle 803 no longer limits the mounting block 801, which can realize the quick disassembly and assembly of the oiling roller 307, making it convenient for daily maintenance and replacement.

[0026] The cleaning structure 5 includes a connecting plate 501 fixedly connected to the press body 1 and a drive shaft 502 rotatably connected to the connecting plate 501. A plug 504 is fixedly connected to the drive shaft 502, and a fixed shaft 505 is inserted into the plug 504. A cleaning brush 506 is installed on the fixed shaft 505. A support plate 507 is slidably connected to the press body 1. The drive shaft 502 is rotatably connected to the support plate 507. A first driving member 503 is installed on the connecting plate 501. The drive shaft 502 is driven to rotate by the first driving member 503. A dust suction hood 508 is installed on the press body 1.

[0027] In practical use, the first driving component 503 (preferably a motor) is started, and the first driving component 503 drives the transmission shaft 502 to rotate. The transmission shaft 502 drives the fixed shaft 505 and the cleaning brush 506 to rotate synchronously through the insert block 504. The cleaning brush 506 contacts the upper surface of the copper strip and removes the copper powder, impurities and debris attached to its surface, so as to avoid the powder impurities on the surface of the copper strip from affecting the stamping quality. The dust suction hood 508 on the stamping machine body 1 sucks away the dust generated by cleaning in real time, further preventing the powder residue from having an adverse effect on subsequent processes.

[0028] The support plate 507 is fixed to the press body 1 by the limiting structure 6. The limiting structure 6 includes a fixed sleeve 601 fixedly connected to the support plate 507 and a pin 602 slidably connected to the fixed sleeve 601. A guide rail 603 is fixedly connected to the press body 1. The support plate 507 is slidably connected to the guide rail 603. The guide rail 603 is provided with two insertion holes 604. The pin 602 is inserted into one of the insertion holes 604. A connecting ring 605 is fixedly connected to the pin 602. A spring 606 is fixedly connected between the connecting ring 605 and the fixed sleeve 601.

[0029] In practical use, when it is necessary to replace the cleaning brush 506, pull the pin 602 upward to disengage it from the insertion hole 604 on the guide rail 603, slide the support plate 507 outward along the guide rail 603, and the fixed shaft 505 and the cleaning brush 506 can be quickly removed. After releasing the pin 602, the pin 602 will automatically reset under the action of the spring 606 and be inserted into another insertion hole 604 to achieve positioning, thereby realizing the quick disassembly and replacement of the cleaning brush 506 and ensuring a stable and reliable cleaning process.

[0030] The detection structure 7 includes a rotating shaft 701 fixedly connected to the press body 1 and a feeding hopper 702 rotatably connected to the rotating shaft 701. An adjusting shaft 707 is rotatably connected to the feeding hopper 702. A material distribution plate 708 is fixedly connected to the adjusting shaft 707. A vision camera 706 is installed on the press body 1. A limit plate 703 is fixedly connected to the feeding hopper 702. A first torsion spring 704 is fixedly connected between the feeding hopper 702 and the press body 1. A vibration motor 705 is installed on the feeding hopper 702. A second driving component 709 is installed on the feeding hopper 702. The adjusting shaft 707 is driven to rotate by the second driving component 709.

[0031] In practical use, when the vision camera 706 detects a qualified product, the second drive unit 709 (preferably a motor) is activated. The second drive unit 709 drives the adjusting shaft 707 to rotate, causing the material distribution plate 708 to swing to the qualified product discharge direction. The qualified product falls into the corresponding collection area along the hopper 702. When a non-qualified product is detected, the second drive unit 709 drives the material distribution plate 708 to switch to the non-qualified product discharge direction, automatically separating the non-qualified product into a separate area. This achieves automatic sorting of qualified and non-qualified products, avoiding the problems of low efficiency and easy omissions in manual screening, and improving the product qualification rate and the degree of automation of the device.

[0032] Working principle: First, the surface of the copper strip is cleaned. The copper strip is conveyed along the stamping machine body 1 to the cleaning brush 506. The first drive unit 503 (preferably a motor) is started, which drives the transmission shaft 502 to rotate. The transmission shaft 502 drives the fixed shaft 505 and the cleaning brush 506 to rotate synchronously through the insert block 504. The cleaning brush 506 contacts the upper surface of the copper strip and removes the copper powder, impurities and debris attached to its surface, so as to avoid the powder impurities on the surface of the copper strip from affecting the stamping quality. The dust suction hood 508 on the stamping machine body 1 removes the cleaning products. The dust is sucked away in real time to further prevent powder residue from adversely affecting subsequent processes. When the cleaning brush 506 needs to be replaced, pull the pin 602 upward to disengage it from the insertion hole 604 on the guide rail 603, slide the support plate 507 outward along the guide rail 603, and the fixed shaft 505 and cleaning brush 506 can be quickly removed. After releasing the pin 602, the pin 602 will automatically reset under the action of the spring 606 and be inserted into another insertion hole 604 to achieve positioning, thereby realizing the quick disassembly and replacement of the cleaning brush 506 and ensuring the stability and reliability of the cleaning process. Secondly, the cleaned copper strip is conveyed to the oiling station for uniform oiling. The crank drive assembly 204 uses a motor to drive the crank to rotate, converting the rotational motion into the vertical reciprocating motion of the connecting rod driving the slider 201, providing stable and continuous power for stamping. While the slider 201 moves up and down, it drives the mounting plate 205 and the inclined groove 206 to move synchronously. The inclined groove 206 rolls with the drive shaft 303, and the drive slide rod 302 slides horizontally along the fixed rod 301. The roller on the fixed rod 301 reduces the friction of the slide rod 302. The slide rod 302 drives the mounting base 305, the connecting shaft 306, and the oiling roller 307 to move synchronously through the connecting seat 304. The gear 308 on the connecting shaft 306 engages with the rack 3 on the stamping machine body 1. 09 Engagement allows the oiling roller 307 to rotate simultaneously during movement. The oil pump 403 delivers lubricating oil from the oil storage tank 401 to the oiling roller 307 through the first connecting pipe 402 and the second connecting pipe 404, ensuring that the lubricating oil is evenly adhered to the surface of the oiling roller 307 and evenly coated on the surface of the copper strip as it rolls. This avoids problems such as localized concentrated oiling and poor lubrication, effectively reducing wear between the mold and the workpiece, and improving the smoothness of the copper needle forming surface. The mounting base 305 is inserted into the connecting base 304 through the mounting block 801. When disassembling, rotating the baffle 803 causes the second torsion spring 804 to deform, and the baffle 803 no longer limits the mounting block 801, thus enabling quick disassembly and assembly of the oiling roller 307, facilitating daily maintenance and replacement. Finally, the stamped copper needles enter the inspection and automatic sorting station. The vision camera 706 on the stamping machine body 1 performs real-time image acquisition and quality inspection on the falling copper needles to determine whether the product is qualified. The feeding hopper 702 is rotatably mounted on the stamping machine body 1 via the rotating shaft 701. Under the action of the first torsion spring 704 and the limiting plate 703, it can achieve a small amplitude swing. Combined with the micro-vibration generated by the vibration motor 705, it makes the copper needles fall smoothly and avoid jamming. At the same time, the vibration of the stamping machine itself can be used to further assist the feeding and improve the feeding reliability. When the vision camera 706 When a product is detected as qualified, the second drive unit 709 (preferably a motor) is activated. The second drive unit 709 drives the adjusting shaft 707 to rotate, causing the material distribution plate 708 to swing to the direction of qualified product discharge. Qualified products fall into the corresponding collection area along the hopper 702. When a product is detected as unqualified, the second drive unit 709 drives the material distribution plate 708 to switch to the direction of unqualified product discharge, automatically separating the unqualified product into a separate area. This achieves automatic sorting of qualified and unqualified products, avoiding the problems of low efficiency and easy omissions in manual screening, and improving the product qualification rate and the degree of automation of the device.
