Detailed implementation manner

[0028] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0029] As Figure 1 , Figure 3 and Figure 4 shown, a continuous stamping machine for metal parts according to an embodiment of the present invention includes a stamping body 1; a processing groove is opened on one side of the stamping body 1; the inner wall of the end of the processing groove is fixedly connected with a hydraulic cylinder 11; the output end of the hydraulic cylinder 11 is fixedly connected with a sliding frame 12, and the sliding frame 12 is slidably connected to the inner wall of the processing groove; a plurality of fixed blocks 13 are fixedly connected to the bottom end of the sliding frame 12; an insertion block 14 is inserted into the inside of the plurality of fixed blocks 13; the bottom end of the insertion block 14 is fixedly connected with an upper die 15, and the upper die 15 is fixedly connected to the bottom ends of the plurality of insertion blocks 14; an insertion assembly is arranged on the inner walls of the plurality of fixed blocks 13, and the insertion assembly is used to cooperate with the fixed blocks 13 to limit the insertion block 14; when continuously stamping metal parts, taking the stamping body 1 as the main framework of the metal part connecting stamping machine, the protruding parts of the plurality of insertion blocks 14 on the upper die 15 are slidably inserted into the inside of the fixed blocks 13, and the insertion block 14 is fixed and limited in the fixed block 13 by relying on the insertion assembly. The bottom of the upper die 15 aggregates a plurality of stamping blocks. When stamping a metal plate, the long strip-shaped metal plate is intermittently conveyed at the processing groove below the upper die 15. The output end of the hydraulic cylinder 11 drives the sliding frame 12 to slide down, synchronously driving the plurality of stamping blocks at the bottom of the upper die 15 to stamp the metal plate. As the metal plate is intermittently conveyed, the upper die 15 continuously stamps the metal plate to achieve multiple shapes. When replacing the upper die 15, the limit on the plurality of insertion blocks 14 by the insertion assembly is released, the upper die 15 is removed, and a different model of the upper die 15 is replaced and then fixed by inserting the insertion block 14 into the fixed block 13 again, which can quickly replace the die and is convenient for stamping and manufacturing metal parts of multiple models, thereby improving the production capacity of metal parts.

[0030] The plug-in component includes a plug rod 2, a first elastic member 21, and a mating slide plate 22. The plug rod 2 is inserted into the interior of the fixed block 13 and penetrates through the plug-in block 14. A disc is provided at the bottom end of the plug rod 2. The first elastic member 21 is sleeved on the plug rod 2 and is fixedly connected between the inner wall of the fixed block 13 and the disc. The mating slide plate 22 is fixedly connected to the outer wall of the plug rod 2 and is slidably connected to the inner wall of the fixed block 13. When quickly replacing the upper die 15, press the mating slide plate 22 to slide down along the inner wall of the fixed block 13. The mating slide plate 22 synchronously drives the plug rod 2 to slide down inside the fixed block 13, and the first elastic member 21 is pulled and stressed. At this time, the plug rod 2 slides out of the interior of the plug-in block 14, and the plug-in block 14 is taken out from the interior of the fixed block 13, and then the old upper die 15 can be removed. Subsequently, insert the plug-in block 14 on the new upper die 15 into the interior of the fixed block 13, and release the mating slide plate 22. The mating slide plate 22 is pulled by the elastic reset of the first elastic member 21, so that the plug rod 2 penetrates through the plug-in block 14 and is inserted into the interior of the fixed block 13, playing a role in quickly replacing the upper die 15.

[0031] As Figure 1 and Figure 2 shown, a lower die 3 is placed on the bottom inner wall of the processing groove. Circular holes are formed on both sides of the lower die 3. A limiting rod 31 is slidably connected to the inner wall of the stamping machine body 1 through a first spring, and the limiting rod 31 is correspondingly arranged with the circular holes. In order to improve the stamping effect on the metal part, the lower die 3 is placed in the processing groove and used in cooperation with the upper die 15. During the process of placing the lower die 3 at the bottom of the processing groove, it is necessary to squeeze the limiting rods 31 on both sides of the stamping machine body 1 to retract into the interior of the stamping machine body 1. The two limiting rods 31 synchronously squeeze the first spring to contract. When the circular holes on both sides of the lower die 3 correspond to the two limiting rods 31, the elastic force of the first spring squeezes the limiting rod 31 to reset, so that the limiting rod 31 is stuck into the circular hole, playing a role in installing the lower die 3. When disassembling the lower die 3, press the limiting rod 31 into the inner wall of the stamping machine body 1 to take out the lower die 3.

[0032] Both inner walls of the stamping machine body 1 are slidably connected with support plates 4 through second springs. The two support plates 4 are located at the position of the limiting rods 31. When installing the lower die 3, the lower die 3 squeezes the support plates 4 to slide down along the inner wall of the stamping machine body 1. The second springs at the bottom ends of the support plates 4 are squeezed and contracted under stress until the two limiting rods 31 are stuck into the two circular holes of the lower die 3, and the installation of the lower die 3 is completed. When the lower die 3 is matched and replaced according to the upper die 15, the limitation of the two limiting rods 31 on the lower die 3 is released, and the second springs at the bottom ends of the support plates 4 are elastically reset, driving the support plates 4 to jack up the lower die 3 for convenient picking up, playing a role in quickly replacing the lower die 3 by jacking it out.

[0033] As Figure 1 , Figure 3 , Figure 5 andFigure 6 As shown in the figure, a fixing frame 5 is provided on one side of the upper die 15; a pressing rod 51 is slidably connected through the inner wall of the fixing frame 5; the bottom end of the pressing rod 51 is fixedly connected with a scraping block 52, and the side of the scraping block 52 away from the stamping machine body 1 is set as an inclined surface; a second elastic member 53 is sleeved on the outer wall of the pressing rod 51, and the second elastic member 53 is fixedly connected between the fixing frame 5 and the scraping block 52; a connecting component is arranged between the upper die 15 and the fixing frame 5, and the connecting component is used for connecting and installing the upper die 15 and the fixing frame 5; before continuously stamping the metal plate, since impurities are easily attached to the surface of the metal plate, the residue of the impurities affects the stamping effect of the metal plate. The fixing frame 5 is installed at the front end of the upper die 15 by using the connecting component, above the feeding position of the processing groove. The scraping block 52 connected to the bottom end of the pressing rod 51 is attached to the upper end surface of the conveyed metal plate. The second elastic member 53 is sleeved on the outer wall of the pressing rod 51 to assist in supporting. As the metal plate is intermittently conveyed, the inclined surface of the scraping block 52 scrapes the surface of the metal plate, reducing the attachment of impurities on the surface of the metal plate and improving the continuous stamping effect on the metal plate.

[0034] As Figure 1 、 Figures 3 to 5 As shown in the figure, the connecting component includes a connecting plate 6 and a bolt 61; the two connecting plates 6 are fixedly connected to the side of the upper die 15 close to the fixing frame 5, and the two connecting plates 6 are inserted into the fixing frame 5; the two bolts 61 are threadedly connected in the fixing frame 5, and the bolts 61 penetrate through the connecting plate 6; when the fixing frame 5 is installed at the front end of the upper die 15, the fixing frame 5 is inserted on the two connecting plates 6, and the two connecting plates 6 enter the fixing frame 5. Two bolts 61 are threadedly connected in the fixing frame 5, and the bolts 61 penetrate through the connecting plate 6, so as to play a role in fixedly installing the fixing frame 5.

[0035] A collection groove 7 is formed on one side of the scraping block 52; the collection groove 7 is located at the inclined surface of the scraping block 52; when scraping the impurities on the surface of the metal plate, the scraped impurities remain at the scraping block 52, affecting the scraping effect of the scraping block 52 on the metal plate. The collection groove 7 is relied on to collect the scraped impurities, reducing the accumulation of impurities at the scraping block 52 and improving the scraping effect of the scraping block 52 on the impurities on the metal plate.

[0036] As Figure 1 、 Figures 3 to 6As shown, an extrusion box 8 is fixedly connected to the end of the fixing frame 5, and an extrusion rod 51 is slidably connected inside the extrusion box 8; a connecting pipe 81 is fixedly connected to one side of the extrusion box 8 close to the stamping machine body 1; a first diversion pipe 82 is fixedly connected to the side of the connecting pipe 81 away from the extrusion box 8; a spraying plate 83 is fixedly connected to the bottom end of the first diversion pipe 82; before continuously stamping the metal plate, lubricating oil can be sprayed on the surface of the metal plate. The lubricating oil can form a lubricating film between the mold and the workpiece, reducing friction and wear, as well as reducing the stamping force and having the functions of cooling and rust prevention. Therefore, the lubricating oil is added to the inside of the extrusion box 8. As the upper mold 15 stamps the metal plate, the upper mold 15 synchronously drives the fixing frame 5 to extrude the second elastic member 53 to contract and slide down the outer wall of the extrusion rod 51. The extrusion box 8 slides down synchronously with the fixing frame 5 and fits on the metal plate. The scraping block 52 supports the extrusion rod 51 and squeezes the lubricating oil inside the extrusion box 8, blocking the oil inlet at the top end of the extrusion box 8. The stamped metal plate is not easily bent and can sufficiently support the extrusion rod 51 on the scraping block 52 to squeeze the lubricating oil inside the extrusion box 8. The lubricating oil squeezed inside the extrusion box 8 is sent to the spraying plate 83 through the connecting pipe 81 and the first diversion pipe 82, and the spraying plate 83 pre-sprays the lubricating oil on the position of the metal plate that needs to be stamped, improving the effect of continuously stamping the metal plate.

[0037] A fuel tank 9 is fixedly connected to one side of the sliding frame 12 close to the extrusion box 8; a second diversion pipe 91 is fixedly connected to the outer wall of the fuel tank 9; a one-way valve 92 is threadedly connected to the top end of the extrusion box 8, and one end of the one-way valve 92 away from the extrusion box 8 is connected to the second diversion pipe 91; when filling the inside of the extrusion box 8 with oil, the lubricating oil is first stored in the fuel tank 9. The lubricating oil in the fuel tank 9 is sent to the one-way valve 92 from high to low through the second diversion pipe 91 and falls into the extrusion box 8 through the one-way valve 92 to wait for extrusion, playing a role in filling the extrusion box 8 with oil. When the extrusion rod 51 squeezes the lubricating oil inside the extrusion box 8, due to the one-way valve 92 being designed to only allow oil to enter and not exit, the lubricating oil squeezed inside the extrusion box 8 is sent out from the connecting pipe 81 on one side, playing a role in controlling the outlet and conveying the lubricating oil inside the extrusion box 8. The second diversion pipe 91 is made of a flexible material and can bend and deform when the extrusion box 8 slides down.

[0038] A sealing ring plate 93 is fixedly connected to the inner wall of the connecting pipe 81; a sealing ball 94 is fixedly connected to the outer wall of the second diversion pipe 91 through an elastic pull rope; when the lubricating oil in the extrusion box 8 is extruded and sprayed, the one-way valve 92 seals the oil inlet at the top of the extrusion box 8, and the lubricating oil in the extrusion box 8 is extruded into the connecting pipe 81. As the extrusion rod 51 extrudes the lubricating oil in the extrusion box 8, when the pressure is greater than the tension of the elastic pull rope, the lubricating oil flushes into the first diversion pipe 82 from between the sealing ball 94 and the sealing ring plate 93 for transportation. After the lubricating oil in the extrusion box 8 is extruded, the elastic pull rope on the sealing ring plate 93 pulls the sealing ball 94 back to its original position to seal the internal passage of the connecting pipe 81, and the one-way valve 92 continues to inject oil into the interior of the extrusion box 8, playing a role in internal control and sealing of the connecting pipe 81.

[0039] Working process: When continuously stamping metal parts, the stamping machine body 1 is used as the main framework for connecting the stamping machine to the metal parts. The protruding parts of the plurality of plug-in blocks 14 on the upper die 15 are slidably inserted into the interior of the fixed block 13, and the plug-in blocks 14 are fixed and limited within the fixed block 13 by the plug-in assembly. The bottom of the upper die 15 is assembled with a plurality of stamping blocks. When stamping a metal plate, the long strip-shaped metal plate is intermittently conveyed at the processing groove below the upper die 15. The output end of the hydraulic cylinder 11 drives the sliding frame 12 to slide downward, synchronously driving the plurality of stamping blocks at the bottom of the upper die 15 to stamp the metal plate. As the metal plate is intermittently conveyed, the upper die 15 continuously stamps the metal plate to achieve multiple shaping. When replacing the upper die 15, the limit on the plurality of plug-in blocks 14 by the plug-in assembly is released, and the upper die 15 is removed. Then, a different model of the upper die 15 is replaced and fixed again by inserting the plug-in block 14 into the fixed block 13, which can quickly replace the die and facilitate the stamping manufacturing of multiple models of metal parts, thereby improving the production capacity of metal parts; when quickly replacing the upper die 15, press the cooperation slide plate 22 to slide down the inner wall of the fixed block 13, and the cooperation slide plate 22 synchronously drives the plug rod 2 to slide inside the fixed block 13. The first elastic member 21 is pulled and stressed. At this time, the plug rod 2 slides out of the interior of the plug-in block 14, and the plug-in block 14 is taken out of the interior of the fixed block 13, and then the old upper die 15 can be removed. Subsequently, the plug-in block 14 on the new upper die 15 is inserted into the interior of the fixed block 13, and the cooperation slide plate 22 is released. The cooperation slide plate 22 is pulled back to its original position by the elastic force of the first elastic member 21, so that the plug rod 2 penetrates through the plug-in block 14 and is inserted into the interior of the fixed block 13, playing a role in quickly replacing the upper die 15;

[0040] In order to improve the stamping effect on metal parts, the lower die 3 is placed in the processing groove and used in cooperation with the upper die 15. During the process of placing the lower die 3 at the bottom of the processing groove, the limiting rods 31 on both sides of the stamping machine body 1 need to be squeezed and retracted into the interior of the stamping machine body 1. The two limiting rods 31 synchronously squeeze the first spring to contract. When the round holes on both sides of the lower die 3 correspond to the two limiting rods 31, the elastic force of the first spring squeezes the limiting rods 31 to reset, so that the limiting rods 31 are stuck into the round holes, playing a role in installing the lower die 3. When disassembling the lower die 3, the limiting rods 31 are pressed into the inner wall of the stamping machine body 1 to remove the lower die 3; when installing the lower die 3, the lower die 3 squeezes the support plate 4 to slide down on the inner wall of the stamping machine body 1, and the second spring at the bottom end of the support plate 4 is squeezed and contracted to be stressed until the two limiting rods 31 are stuck into the two round holes of the lower die 3, completing the installation of the lower die 3. When the lower die 3 is matched and replaced according to the upper die 15, the limitation of the two limiting rods 31 on the lower die 3 is released, and the elastic force of the second spring at the bottom end of the support plate 4 resets, driving the support plate 4 to lift the lower die 3 for easy picking, playing a role in quickly replacing the lower die 3 by ejecting it;

[0041] Before continuously stamping the metal plate, since impurities are likely to adhere to the surface of the metal plate, and the residue of impurities affects the stamping effect of the metal plate. The fixing frame 5 is installed at the front end of the upper die 15 by using the connecting component, above the feeding position of the processing groove. The scraping block 52 connected to the bottom end of the extrusion rod 51 fits on the upper end surface of the conveyed metal plate. The second elastic member 53 is sleeved on the outer wall of the extrusion rod 51 to assist in supporting. As the metal plate is intermittently conveyed, the inclined surface of the scraping block 52 scrapes the surface of the metal plate, reducing the adhesion of impurities on the surface of the metal plate and improving the continuous stamping effect on the metal plate; when the fixing frame 5 is installed at the front end of the upper die 15, the fixing frame 5 is inserted on the two connecting plates 6. The two connecting plates 6 enter the interior of the fixing frame 5. Two bolts 61 are threaded into the interior of the fixing frame 5, and the bolts 61 penetrate the connecting plates 6, thereby playing a role in fixedly installing the fixing frame 5; when scraping the impurities on the surface of the metal plate, the scraped impurities remain at the scraping block 52, affecting the scraping effect of the scraping block 52 on the metal plate. The collecting groove 7 is relied on to collect the scraped impurities, reducing the accumulation of impurities at the scraping block 52 and improving the scraping effect of the scraping block 52 on the impurities on the metal plate;

[0042] Before continuously stamping a metal plate, lubricating oil can be sprayed on the surface of the metal plate. The lubricating oil can form a lubricating film between the mold and the workpiece, reducing friction and wear, as well as reducing the stamping force and having the functions of cooling and rust prevention. Therefore, the lubricating oil is added to the inside of the extrusion box 8. As the upper mold 15 stamps the metal plate, the upper mold 15 synchronously drives the fixing frame 5 to squeeze the second elastic member 53 to contract and slide down the outer wall of the extrusion rod 51. The extrusion box 8 slides down synchronously with the fixing frame 5. The shovel block 52 attached to the metal plate supports the extrusion rod 51 and squeezes the lubricating oil inside the extrusion box 8, blocking the oil inlet at the top of the extrusion box 8. The stamped metal plate is not easily bent and is sufficient to support the extrusion rod 51 on the shovel block 52 to squeeze the lubricating oil inside the extrusion box 8. The lubricating oil squeezed inside the extrusion box 8 is sent to the spray plate 83 through the connecting pipe 81 and the first diversion pipe 82, and the spray plate 83 pre-sprays the lubricating oil at the position where the metal plate needs to be stamped, improving the effect of continuously stamping the metal plate; when injecting oil into the inside of the extrusion box 8, the lubricating oil is first stored in the oil tank 9. The lubricating oil in the oil tank 9 is sent from high to low to the one-way valve 92 through the second diversion pipe 91, and then falls into the extrusion box 8 through the one-way valve 92 to wait for extrusion, playing the role of injecting oil into the extrusion box 8. When the extrusion rod 51 squeezes the lubricating oil inside the extrusion box 8, due to the setting of the one-way valve 92 that only allows oil to enter but not exit, the lubricating oil squeezed inside the extrusion box 8 is sent out from the connecting pipe 81 on one side, playing the role of controlling the outlet delivery of the lubricating oil inside the extrusion box 8. The material of the second diversion pipe 91 is a flexible material, and the second diversion pipe 91 can be bent and deformed when the extrusion box 8 slides down; when squeezing and spraying the lubricating oil inside the extrusion box 8, the one-way valve 92 blocks the oil inlet at the top of the extrusion box 8. The lubricating oil inside the extrusion box 8 is squeezed into the connecting pipe 81. As the extrusion rod 51 squeezes the lubricating oil inside the extrusion box 8 and the pressure is greater than the pulling force of the elastic cord, the lubricating oil rushes into the first diversion pipe 82 from between the blocking ball 94 and the blocking ring plate 93 for delivery. After the lubricating oil inside the extrusion box 8 is squeezed out, the elastic cord on the blocking ring plate 93 pulls the blocking ball 94 back to its original position to block the internal passage of the connecting pipe 81, and the one-way valve 92 continues to inject oil into the inside of the extrusion box 8, playing the role of internal control and blocking of the connecting pipe 81.
