Description

TECHNICAL FIELD

[0002] The stainless steel hoop stamping equipment is a special machine combining stamping forming technology and the characteristics of stainless steel material. Traditional hoop production relies on turning, welding and other processes, which has problems such as low efficiency and poor precision. With the development of stamping technology, hydraulic / mechanical presses are used to cooperate with customized dies to realize the integration of hoop bending production.

[0003] A patent with publication number CN219899807U discloses a stainless steel plate stamping device, which comprises a lower die, a top plate, an upper die, a connecting plate and an ejection plate. The four corners of the top of the lower die are fixedly connected with guide columns. The top of the top plate is fixedly installed with a stamping cylinder. The output end of the stamping cylinder is fixedly connected with a guide plate through the top plate. The bottom of the guide plate is fixedly connected with high-density rubber blocks. The bottom of the U-shaped plate is fixedly connected with a plurality of spring columns. The bottom of the spring columns is fixedly connected with the top of the upper die. The top of the lower die is provided with a forming cavity. The bottom of the forming cavity is provided with an extrusion cavity. The four corners of the inner cavity of the extrusion cavity are fixedly connected with stabilizing columns. The surface of the bottom of the stabilizing column is sleeved with a return spring. The surface of the top of the stabilizing column is sleeved with a sliding sleeve. The stainless steel plate stamping device can conveniently take out the formed steel plate when the upper die and the forming cavity are separated.

[0004] In the existing stainless steel plate stamping production process, when manufacturing stainless steel hoops, the cut stainless steel plate is placed stably on the stamping table. Then, the stamping roller slowly moves downward and precisely extrudes the stainless steel plate into the preset groove by the powerful pressure to complete the stamping forming of the stainless steel hoop. However, in the actual production process, due to the surface of the stainless steel plate may be attached with some small steel slag in the previous processing and transportation, etc. During the stamping operation, these steel slag is easily attached to the circumference of the stamping roller and forms a close mechanical stress connection with the stamping roller. When the next stamping starts, the stamping roller operates again. These attached steel slag will stamp irregular holes on the surface of the new stainless steel plate, seriously damaging the surface quality of the steel plate and causing the product unqualified rate to rise. In order to avoid the continuous deterioration of this situation, it is necessary to stop the machine and arrange special personnel to clean the stamping roller thoroughly, which increases the production cost and production cycle.

However, in the actual production process, since the surface of the stainless steel plate may be attached with some small steel slag in the previous processing and transportation, etc., the steel slag is easily attached to the circumferential surface of the pressing roller 24 during the stamping operation, and forms a close mechanical stress connection with the pressing roller 24. When the next stamping starts, the pressing roller 24 operates again, and the steel slag attached thereto will stamp irregular holes on the surface of the new stainless steel plate, seriously damaging the surface quality of the steel plate and causing the product unqualified rate to rise. In order to avoid the continuous deterioration of the situation, it is necessary to stop the machine and arrange special personnel to clean the pressing roller 24 in detail, which increases the production cost and production cycle.

[0034] Therefore, the present application is set according to the above-mentioned problems, first, when stamping work is carried out, the stainless steel plate is placed on the fixed table 25, then the second hydraulic cylinder 22 is started, the second hydraulic cylinder 22 drives the pressing plate 23 to drive the pressing roller 24 to extrude the stainless steel plate downward, and the stamping is fitted with the groove on the fixed table 25, and the stamping work of the stainless steel plate is completed. After the stamping work is completed, the first hydraulic cylinder 21 is started, the first hydraulic cylinder 21 drives the fixed plate 27 and the fixed disc 28 at the output end to move to the lower side of the pressing roller 24, in the process, the auxiliary ring 210 pushes the stamping formed stainless steel hoop away from the fixed table 25, at the same time, the fixed ring 29 abuts against the lower surface of the pressing roller 24, the built-in motor of the fixed disc 28 is started, the fixed gear 216 is driven to rotate, the rotation of the fixed gear 216 drives the auxiliary gear 217 to rotate along the gear ring 215, the auxiliary gear 217 moves along the annular track formed by the fixed gear 216 and the gear ring 215, and the auxiliary gear 217 can drive the connecting shaft 212 on one side to abut against the lower half of the pressing roller 24, and the scraper 218 on the circumference of the connecting shaft 212 can scrape off the steel slag on the surface of the pressing roller 24, and the scraped off steel slag falls into the fixed groove 214 in the fixed ring 29 for unified collection.

[0035] Through the cooperation of the first hydraulic cylinder 21 and the second hydraulic cylinder 22, the stamping of the stainless steel plate is efficiently completed, after stamping, the auxiliary ring 210 automatically pushes away the formed hoop, improves the production fluency, the built-in motor of the fixed disc 28 drives the gear system, the scraper 218 moves along the lower half of the pressing roller 24, effectively scrapes off the steel slag, prevents the influence on the subsequent stamping quality, the fixed ring 29 cooperates with the fixed groove 214 to realize unified collection of the steel slag, reduces the cleaning cost, and improves the production efficiency and product quality.

[0036] As shown in Figure 6 the circumference of the connecting shaft 212 is also fixedly connected with a plurality of cleaning blocks 219, the plurality of cleaning blocks 219 are made of sponge material and are interlaced with the scraper 218 and are fixedly connected on the circumference of the connecting shaft 212 in a circumferential array.

[0037] Specifically, the scraper 218 is responsible for forcibly scraping off the stubborn steel slag on the surface of the pressing roller 24, and the cleaning block 219 can further wipe the residual small particles and apply lubricating oil, realizing seamless connection from rough cleaning to fine cleaning, and the circumferential array arrangement ensures 360° dead angle cleaning, and the softness of the sponge can also avoid damaging the surface of the pressing roller 24, prolonging the service life of the equipment and improving the surface quality of the subsequent stamping products.

[0038] Embodiment two: as Figures 1 to 8As shown, the comparative example one, wherein another embodiment of the application is: the coating assembly comprises a storage box 26 fixed on one side of the fixed ring 29, the top wall of the fixed ring 29 is fixed with two springs 223, the bottom end of the two springs 223 is fixed with the same positioning plate 221, the upper surface of the positioning plate 221 is fixed with the convex plate 222, the inside of the storage box 26 is provided with the limiting groove 225, the inner wall of the limiting groove 225 is fixed with a plurality of compression springs 226, one end of the plurality of compression springs 226 is fixed with the same tapered plate 224, one side of the tapered plate 224 is fixed with a plurality of telescopic pipes 227, the telescopic pipes 227 are fixed with the storage box 26, the other side of the tapered plate 224 is provided with a plurality of fixing holes 228, and one side of the convex plate 222 is provided with a plurality of auxiliary holes 229.

[0039] Specifically, when the connecting shaft 212 moves to the top end of the side of the fixed ring 29, the positioning plate 221 extrudes the top wall of the fixed ring 29, the positioning plate 221 compresses the spring 223 to move upward, and then extrudes the convex plate 222 to move upward, the upward movement of the convex plate 222 extrudes the tapered plate 224 to retract into the limiting groove 225, and at the same time extrudes the compression spring 226 and the telescopic pipe 227, the telescopic pipe 227 communicates the oil storage cavity in the storage box 26, when the convex plate 222 is extruded to the top, the auxiliary hole 229 on one side of the convex plate 222 is aligned with the fixing hole 228 on one side of the tapered plate 224, at this time the lubricating oil in the storage cavity flows along the telescopic pipe 227 to the fixing hole 228 and the auxiliary hole 229, and then flows from the hole on the lower surface of the positioning plate 221 to the cleaning block 219 on the surface of the connecting shaft 212, and then the connecting shaft 212 is reset under the reverse rotation of the fixed gear 216, at this time the cleaning block 219 can perform the lubricating oil coating work on the compression roller 24;

[0040] When the connecting shaft 212 moves to the top to trigger the positioning plate 221, a series of extrusion actions open the lubricating channel, so that the lubricating oil in the storage box 26 is transported to the cleaning block 219 through the telescopic pipe 227, this immersion method not only ensures the uniform distribution of the lubricating oil, but also avoids the waste and pollution caused by direct spraying, during the resetting process of the connecting shaft 212, the immersed cleaning block 219 can perform comprehensive coating on the compression roller 24, effectively reducing the equipment wear and tear, prolonging the service life of the compression roller 24, and at the same time improving the surface precision of the stamping product, forming a clean-lubricating-maintenance integrated closed loop, significantly improving the production efficiency and equipment stability.

[0041] When the punching work is performed, the stainless steel plate is placed on the fixed table 25, and then the second hydraulic cylinder 22 is started. The second hydraulic cylinder 22 drives the pressing plate 23 to drive the pressing roller 24 to press downward on the stainless steel plate, so that the stainless steel plate is punched to fit the groove on the fixed table 25, and the punching work of the stainless steel plate is completed. After the punching work is completed, the first hydraulic cylinder 21 is started. The first hydraulic cylinder 21 drives the fixed plate 27 and the fixed disc 28 at the output end to move to the lower side of the pressing roller 24. In the process, the auxiliary ring 210 pushes the punched stainless steel hoop away from the fixed table 25, and the fixed ring 29 abuts against the lower surface of the pressing roller 24. The built-in motor of the fixed disc 28 is started, and the fixed gear 216 is driven to rotate. The rotation of the fixed gear 216 drives the auxiliary gear 217 to rotate along the gear ring 215. The auxiliary gear 217 moves along the annular track formed by the fixed gear 216 and the gear ring 215. The auxiliary gear 217 can drive the connecting shaft 212 on one side to abut against the lower half of the pressing roller 24. The scraper 218 on the circumference of the connecting shaft 212 can scrape off the steel slag on the surface of the pressing roller 24. The scraped steel slag falls into the fixed groove 214 in the fixed ring 29 for unified collection.

[0042] Through the cooperation of the first hydraulic cylinder 21 and the second hydraulic cylinder 22, the stainless steel plate is efficiently punched. After punching, the auxiliary ring 210 automatically pushes away the formed hoop, improving the production flow. The built-in motor of the fixed disc 28 drives the gear system, so that the scraper 218 moves accurately along the lower half of the pressing roller 24, effectively scraping off the steel slag to prevent it from affecting the quality of subsequent punching. The fixed ring 29 cooperates with the fixed groove 214 to realize unified collection of the steel slag, reduce cleaning cost, and improve production efficiency and product quality as a whole.

[0043] When the connecting shaft 212 moves to the top of the fixed ring 29, the positioning plate 221 presses the spring 223 to move upward, and then the protruding plate 222 moves upward, which presses the tapered plate 224 to retract into the limiting groove 225, and at the same time, the spring 226 and the telescopic pipe 227 are pressed. The telescopic pipe 227 communicates with the oil storage cavity in the storage tank 26. When the protruding plate 222 is pressed to the top, the auxiliary hole 229 on one side of the protruding plate 222 is aligned with the fixed hole 228 on one side of the tapered plate 224. At this time, the lubricating oil in the storage cavity flows along the telescopic pipe 227 to the fixed hole 228 and the auxiliary hole 229, and then flows from the hole on the lower surface of the positioning plate 221 to the cleaning block 219 on the surface of the connecting shaft 212 for soaking work. Then the connecting shaft 212 is reset under the reverse rotation of the fixed gear 216. At this time, the cleaning block 219 can perform lubricating oil coating work on the pressing roller 24.

[0044] When the connecting shaft 212 moves to the top end and triggers the positioning plate 221, a series of extrusion actions open the lubrication channel, and the lubricating oil in the storage tank 26 is delivered to the cleaning block 219 through the telescopic pipe 227. This immersion method not only ensures the uniform distribution of lubricating oil, but also avoids waste and pollution caused by direct spraying. During the resetting process of the connecting shaft 212, the immersed cleaning block 219 can coat the compression roller 24 comprehensively, effectively reducing equipment wear and tear, prolonging the service life of the compression roller 24, and improving the surface precision of the stamped product. A clean-lubricate-maintain integrated closed loop is formed, significantly improving production efficiency and equipment stability.
