Description

Technical Field

[0001] The present application relates to the technical field of processing and cleaning parts, and in particular to an oil scraping mechanism. Background Art

[0002] In the manufacturing process of stamping sheet metal, stamping oil is an indispensable part. Its main function is to lubricate the die and sheet metal material, ensuring that the material can flow smoothly through the die during high-speed stamping, avoiding excessive friction heat, thereby protecting the die and improving product quality. However, this also brings another problem: after stamping, a large amount of stamping oil and other impurities will remain on the surface of the sheet metal.

[0003] In order to remove these oil stains and impurities, many manufacturers choose to use hydrocarbon cleaning agents for cleaning. Hydrocarbon cleaning agents can effectively decompose and remove oil stains and restore the cleanliness of the sheet metal surface. However, due to the large amount of oil stains generated during the stamping process, the cleaning agent will quickly become turbid and lose its cleaning effect. Therefore, manufacturers need to constantly replace the cleaning agent to ensure the cleaning effect. This not only requires a large amount of hydrocarbon cleaning agents, but also increases manpower and time costs. Workers need to check the clarity of the cleaning agent regularly, and once the cleaning agent becomes turbid, it needs to be replaced immediately. This not only affects production efficiency, but also increases the work intensity of workers. Utility Model Content

[0034] In the manufacturing process of stamping sheet metal, stamping oil is an indispensable part. Its main function is to lubricate the die and sheet metal material, ensuring that the material can flow smoothly through the die during high-speed stamping, avoiding excessive friction heat, thereby protecting the die and improving product quality. However, this also brings another problem: after stamping, a large amount of stamping oil and other impurities will remain on the surface of the sheet metal.

[0035] In order to remove these oil stains and impurities, many manufacturers choose to use hydrocarbon cleaning agents for cleaning. Hydrocarbon cleaning agents can effectively decompose and remove oil stains and restore the cleanliness of the sheet metal surface. However, due to the large amount of oil stains generated during the stamping process, the cleaning agent will quickly become turbid and lose its cleaning effect. Therefore, manufacturers need to constantly replace the cleaning agent to ensure the cleaning effect. This not only requires a large amount of hydrocarbon cleaning agents, but also increases manpower and time costs. Workers need to check the clarity of the cleaning agent regularly, and once the cleaning agent becomes turbid, it needs to be replaced immediately. This not only affects production efficiency, but also increases the work intensity of workers.

[0036] Based on this, the present application provides an oil scraping mechanism to solve the above-mentioned technical problems. The technical solutions provided by the present application are described in detail one by one below.

[0037] Reference Figures 1 to 3The present application provides an oil scraping mechanism, comprising: a first side plate 100, a second side plate 110, a first oil scraping structure 200, a second oil scraping structure 210, a third oil scraping structure 300 and a storage structure, wherein the first side plate 100 and the second side plate 110 are connected on opposite sides by a first guide assembly 120 and a second guide assembly 130, the first guide assembly 120 is arranged above the second guide assembly 130, and an oil scraping channel is formed between the first guide assembly 120, the second guide assembly 130, the first side plate 100 and the second side plate 110; the first oil scraping structure 200 is arranged on the first side plate 100 and is located at the scraping one side of the oil channel; the second oil scraping structure 210 is arranged on the second side plate 110 and is located on the other side of the oil scraping channel; the first oil scraping structure 200 and the second oil scraping structure 210 are respectively used to scrape the stamping oil on the outer wall of the product; the third oil scraping structure 300 is arranged between the first side plate 100 and the second side plate 110 and is located on the lower side of the oil scraping channel; the third oil scraping structure 300 is used to scrape the stamping oil on the bottom of the product; the storage structure is arranged below the first side plate 100 and the second side plate 110, and is used to recover the stamping oil scraped off by the first oil scraping structure 200, the second oil scraping structure 210 and the third oil scraping structure 300. The whole sheet metal is added with stamping oil and punched through a punch press to form a product. The stamping oil can ensure that the product can flow smoothly through the mold during high-speed stamping to avoid excessive friction heat, thereby improving product quality. The product is then sent into an oil scraping channel formed by the first side plate 100, the second side plate 110, the first guide assembly 120 and the second guide assembly 130. In the oil scraping channel, the first guide assembly 120 and the second guide assembly 130 work together to push the product forward. Then, the stamping oil on the outer walls of both sides of the product is scraped off by the first oil scraping structure 200 and the second oil scraping structure 210 arranged on both sides of the oil scraping channel, and the stamping oil on the bottom of the product is scraped off by the third oil scraping structure 300 arranged at the bottom of the oil scraping channel. The stamping oil scraped off by the first oil scraping structure 200, the second oil scraping structure 210 and the third oil scraping structure 300 falls to the storage structure for recovery. The oil scraping structure of the present application can conveniently scrape and collect the stamping oil on the surface of the product, reducing the utilization rate of the stamping oil and the production efficiency of the product.

[0038] Reference Figure 4It can be understood that the first scraper structure 200 includes a first fixed block, a first connecting vertical plate 230 and a first scraper assembly. An opening is provided on the first side plate 100. The first fixed block is arranged on the outer side of the first side plate 100. The first connecting vertical plate 230 is arranged on the first fixed block and is perpendicular to the first fixed block. The first scraper assembly is movably arranged on the first connecting vertical plate 230 and extends from the opening into the scraper passage. Since the first scraper assembly extends from the opening into the scraper passage, this ensures close contact between the scraper and the outer side wall of the product, so that the stamping oil can be scraped off more thoroughly. In addition, since the first scraper assembly is movably arranged on the first connecting vertical plate 230, the first scraper assembly can adjust its position according to the size of the product passing through the scraper passage to achieve a good scraper effect.

[0039] It should be noted that the second oil scraping structure 210 and the first oil scraping structure 200 are symmetrically arranged relative to the oil scraping channel and have similar structures, so the specific structural composition and function of the second oil scraping structure 210 will not be described in detail in this application.

[0040] Continue to refer to Figure 4 It can be understood that the first scraper assembly includes a rotating seat 241, a movable block 242 and a first scraper 243. The rotating seat 241 is arranged on the first connecting vertical plate 230. One end of the movable block 242 is hinged on the rotating seat 241. The other end of the movable block 242 is connected to the first scraper 243. The first scraper 243 extends into the oil scraping channel from the opening. Since the other end of the movable block 242 is connected to the first scraper 243, when the movable block 242 moves on the rotating seat 241, the first scraper 243 can be fine-tuned accordingly, so that the first scraper 243 can better adapt to the shape and size changes of the outer wall of the product, ensure close contact with the outer side of the product, and can more thoroughly scrape off the stamping oil on the outer wall of the product.

[0041] Reference Figures 1 to 3 It can be understood that the angle between the scraping surface of the first scraper 243 and the transmission direction of the oil scraping channel is less than 90°. The scraping surface of the first scraper 243 forms an acute angle with the transmission direction of the oil scraping channel, so that the product contacts the first scraper 243 smoothly, which also means that the contact between the scraping surface of the first scraper 243 and the outer wall of the product is more closely fitted, thereby improving the oil scraping effect.

[0042] Reference Figure 4It is understandable that the first scraper assembly also includes a tension spring 250, one end of which is connected to the first fixed block, and the other end of which is connected to the movable block 242 near the entrance end of the oil scraping channel. When a larger product enters the oil scraping channel, the first scraper 243 is pushed back, so that the first scraper 243 is in close contact with the outer side of the product without damaging the surface of the product, thereby improving the oil scraping effect. When the first scraper 243 changes its position due to the size of the product during the oil scraping process, the elastic force of the tension spring 250 can help the movable block 242 and the first scraper 243 return to their original positions after the product leaves the oil scraping channel.

[0043] Reference Figures 2 to 4 It can be understood that the first connecting vertical plate 230 is provided with an arc-shaped through hole 231, and the rotating seat 241 is provided with a fixing hole 241a. The rotating seat 241 is arranged on the first connecting vertical plate 230 through the connecting piece, passing through the arc-shaped through hole 231 and the fixing hole 241a in sequence. The design of the arc-shaped through hole 231 allows the rotating seat 241 to be rotated and adjusted to a certain extent on the first connecting vertical plate 230. This rotation adjustment enables the first scraper 243 to adapt to the outer side walls of products of different shapes and sizes, ensuring the uniformity and consistency of the oil scraping effect. At the same time, the design of the arc-shaped through hole 231 and the fixing hole 241a makes the installation and removal of the rotating seat 241 simple and convenient. When the first scraper 243 needs to be cleaned or replaced, the rotating seat 241 and the first scraper 243 can be removed from the first connecting vertical plate 230 by simply loosening the connecting piece, thereby simplifying the maintenance process.

[0044] Reference Figure 5 It can be understood that the third scraping structure 300 includes a second fixed block 310, a fine-tuning displacement platform 320, a second connecting vertical plate 330 and a second scraping assembly. The two ends of the second fixed block 310 are respectively connected to the lower ends of the first side plate 100 and the second side plate 110. The fixed end of the fine-tuning displacement platform 320 is arranged on the second fixed block 310. The second connecting vertical plate 330 is arranged at the movable end of the fine-tuning displacement platform 320. The second scraping assembly is arranged at the upper end of the second connecting vertical plate 330 and is located at the lower side of the scraping passage. The fine-tuning displacement platform 320 can adjust the relative position of the second connecting vertical plate 330 and the second fixed block 310, and specifically can adjust the position of the second connecting vertical plate 330 in the horizontal and vertical directions, so that the second scraping assembly can be more adapted to contact with the bottom surface of the product to improve the product scraping effect.

[0045] Continue to refer to Figure 5It can be understood that the second scraper assembly includes a fixed bottom plate 341, a second scraper 342 and a return spring 343. The fixed bottom plate 341 is connected to the upper end of the second connecting vertical plate 330. One side of the second scraper 342 is hinged to the fixed bottom plate 341. The scraping surface of the second scraper 342 is located at the lower side of the oil scraping channel. The two ends of the return spring 343 are respectively connected to the fixed bottom plate 341 and the second scraper 342. When a larger product enters the oil scraping channel, the second scraper 342 is pushed to retract, so that the second scraper 342 is in close contact with the outer side of the product without causing damage to the surface of the product, thereby improving the oil scraping effect. When the second scraper 342 changes its position due to the size of the product during the oil scraping process, the elastic force of the return spring 343 can help the second scraper 342 return to its original position after the product leaves the oil scraping channel.

[0046] Reference Figures 1 to 3 It can be understood that the first guide assembly 120 includes a plurality of guide rollers 121 and vertical adjustment members 122, each guide roller 121 is provided with two corresponding vertical adjustment members 122, the two ends of the guide roller 121 are respectively connected to the opposite sides of the first side plate 100 and the second side plate 110, and the two vertical adjustment members 122 are respectively arranged at the two ends of the corresponding guide roller 121, and are used to adjust the vertical position of the corresponding ends of the guide roller 121. The setting of the guide roller 121 can effectively guide the transmission direction of the product in the oil scraping channel, and ensure that the product passes through the oil scraping area stably and smoothly, which helps to reduce the deviation and swing of the product during the transmission process and improve the oil scraping effect. Through the design of the vertical adjustment member 122, the vertical position of the guide roller 121 can be easily adjusted. This adjustment flexibility enables the first guide assembly 120 to adapt to products of different heights and sizes, and enhances the versatility and adaptability of the oil scraping mechanism. The guide roller 121 uses rolling friction instead of sliding friction, which effectively reduces the resistance of the product during transmission, reduces energy loss, and improves production efficiency.

[0047] Continue to refer to Figures 1 to 3 It can be understood that the first side plate 100 and the second side plate 110 are respectively provided with a third guide assembly 140 at the position of the oil scraping channel. That is, the third guide assembly 140 with a guiding function is also provided in the oil scraping channel. The provision of the third guide assembly 140 further enhances the guiding stability of the product in the oil scraping channel. Since the product may be affected by the force of the first scraper 243 or the second scraper 342, its own gravity and other factors during the oil scraping process, resulting in deviation or shaking, the third guide assembly 140 can effectively correct these deviations, ensuring that the product is always transmitted along the correct path, and the transmission of the product is more stable and smooth, reducing production delays caused by factors such as deviation and shaking.

[0048] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present application.
