DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

A plurality of stamping blocks are assembled at the bottom of the upper mold 15. When stamping the metal plate, the long metal plate is placed in the processing groove and intermittently conveyed below the upper mold 15. The output end of the hydraulic cylinder 11 drives the sliding frame 12 to slide down, and simultaneously drives the plurality of stamping blocks at the bottom of the upper mold 15 to stamp the metal plate. As the metal plate is intermittently conveyed, the upper mold 15 continuously stamps the metal plate to achieve multiple shaping. When replacing the upper mold 15, the limit of the plug-in assembly on the plurality of plug-in blocks 14 is released, and the upper mold 15 of different models is replaced and fixed in the fixed block 13 again by plugging the plug-in block 14. The mold can be quickly replaced, which is convenient for stamping and manufacturing of metal parts of multiple models, thereby improving the production capacity of metal parts.

[0024] The plug-in assembly includes an insert rod 2, a No. 1 elastic member 21 and a matching slide plate 22; the insert rod 2 is inserted into the interior of the fixed block 13, and the insert rod 2 passes through the plug-in block 14, and a disc is provided at the bottom end of the insert rod 2; the No. 1 elastic member 21 is sleeved on the insert rod 2, and the No. 1 elastic member 21 is fixedly connected between the inner wall of the fixed block 13 and the disc; the matching slide plate 22 is fixedly connected to the outer wall of the insert rod 2, and the matching slide plate 22 is slidably connected to the inner wall of the fixed block 13; when the upper mold 15 is quickly replaced, the matching slide plate 22 is pressed to slide down the inner wall of the fixed block 13 , the cooperating slide plate 22 synchronously drives the plug rod 2 to slide down inside the fixed block 13, and the No. 1 elastic member 21 is pulled and stressed. At this time, the plug rod 2 slides out of the plug block 14, and the plug block 14 is taken out from the inside of the fixed block 13 before the old upper mold 15 can be removed, and then the plug block 14 on the new upper mold 15 is inserted into the fixed block 13, and the cooperating slide plate 22 is released. The cooperating slide plate 22 is pulled back by the elastic force of the No. 1 elastic member 21, so that the plug rod 2 passes through the plug block 14 and is plugged into the fixed block 13, which plays a role in quickly replacing the upper mold 15.

[0025] like Figure 1 and Figure 2 As shown, a lower mold 3 is placed on the bottom inner wall of the processing groove; circular holes are opened on both sides of the lower mold 3; the inner wall of the stamping machine body 1 is slidably connected to the limit rod 31 through a No. 1 spring, and the limit rod 31 is set corresponding to the circular hole; in order to improve the stamping effect on the metal part, the lower mold 3 is placed in the processing groove and used in conjunction with the upper mold 15. During the process of placing the lower mold 3 at the bottom of the processing groove, the limit rods 31 on both sides of the stamping machine body 1 need to be squeezed into the inside of the stamping machine body 1, and the two limit rods 31 synchronously squeeze the No. 1 spring to shrink. When the circular holes on both sides of the lower mold 3 correspond to the two limit rods 31, the No. 1 spring elastic force squeezes the limit rod 31 to reset, so that the limit rod 31 is stuck in the circular hole, which plays a role in installing the lower mold 3. When disassembling the lower mold 3, the limit rod 31 is pressed into the inner wall of the stamping machine body 1 to remove the lower mold 3.

[0026] The inner walls on both sides of the stamping machine body 1 are slidably connected with support plates 4 through No. 2 springs; the two support plates 4 are located at the limit rods 31; when the lower mold 3 is installed, the lower mold 3 squeezes the support plates 4 and slides down the inner wall of the stamping machine body 1, and the No. 2 springs at the bottom ends of the support plates 4 are squeezed and contracted until the two limit rods 31 are inserted into the two circular holes of the lower mold 3, and the installation of the lower mold 3 is completed. When the lower mold 3 is replaced according to the upper mold 15, the limit of the two limit rods 31 on the lower mold 3 is released, and the No. 2 spring elastic force at the bottom ends of the support plates 4 is reset, driving the support plates 4 to lift up the lower mold 3 for easy picking, thereby playing a role in quickly replacing the lower mold 3.

[0027] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, a fixing frame 5 is provided on one side of the upper mold 15; an extrusion rod 51 is slidably connected to the inner wall of the fixing frame 5; a shovel block 52 is fixedly connected to the bottom end of the extrusion rod 51, and the side of the shovel 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 extrusion rod 51, and the second elastic member 53 is fixedly connected between the fixing frame 5 and the shovel block 52; a connecting component is provided between the upper mold 15 and the fixing frame 5, and the connecting component is used to connect and install the upper mold 15 and the fixing frame 5; when the metal plate is connected Before continued stamping, since impurities are easily attached to the surface of the metal plate, the residual impurities affect the stamping effect of the metal plate. The fixing frame 5 is installed at the front end of the upper mold 15 using a connecting assembly, located above the feed of the processing groove. The shovel block 52 connected to the bottom end of the extrusion rod 51 is attached to the upper end surface of the conveyed metal plate, and the No. 2 elastic member 53 is sleeved on the outer wall of the extrusion rod 51 for auxiliary support. As the metal plate is intermittently conveyed, the inclined surface of the shovel block 52 scrapes the surface of the metal plate to reduce the attachment of impurities on the surface of the metal plate and improve the continuous stamping effect of the metal plate.

[0028] like Figure 1 , Figures 3 to 5 As shown, the connecting assembly includes a connecting plate 6 and a bolt 61; the two connecting plates 6 are fixedly connected to one side of the upper mold 15 close to the fixing frame 5, and the two connecting plates 6 are inserted into the inside of the fixing frame 5; the two bolts 61 are threadedly connected to the inside of the fixing frame 5, and the bolts 61 pass through the connecting plates 6; when the fixing frame 5 is installed at the front end of the upper mold 15, the fixing frame 5 is inserted into the two connecting plates 6, the two connecting plates 6 enter the inside of the fixing frame 5, and are threadedly connected to the inside of the fixing frame 5 using two bolts 61, and the bolts 61 pass through the connecting plates 6, thereby playing a role in fixing and installing the fixing frame 5.

[0029] A collecting groove 7 is provided on one side of the shovel block 52; the collecting groove 7 is located at the inclined surface of the shovel block 52; when impurities on the surface of the metal plate are scraped, the scraped impurities remain on the shovel block 52, affecting the scraping effect of the shovel block 52 on the metal plate. The impurities scraped by the collecting groove 7 are collected, the accumulation of impurities on the shovel block 52 is reduced, and the scraping effect of the shovel block 52 on the impurities on the metal plate is improved.

[0030] like Figure 1 , Figures 3 to 6As shown, the end of the fixing frame 5 is fixedly connected to an extrusion box 8, and the extrusion rod 51 is slidably connected to the inside of the extrusion box 8; the side of the extrusion box 8 close to the stamping machine body 1 is fixedly connected to a connecting pipe 81; the side of the connecting pipe 81 away from the extrusion box 8 is fixedly connected to a No. 1 guide pipe 82; the bottom end of the No. 1 guide pipe 82 is fixedly connected to a spray plate 83; before the metal plate is continuously stamped, 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, reduce friction and wear, and reduce the stamping force and cool and prevent rust. Therefore, the lubricating oil is added to the inside of the extrusion box 8, and as the upper mold 15 stamps the metal plate, the upper mold The tool 15 synchronously drives the fixing frame 5 to squeeze the No. 2 elastic member 53 to contract and slide down the outer wall of the extrusion rod 51, and the extrusion box 8 slides down synchronously with the fixing frame 5, and the shovel block 52 attached to the metal plate supports the extrusion rod 51 and squeezes the lubricating oil inside the extrusion box 8, and the top oil inlet of the extrusion box 8 is blocked. The stamped metal plate is not easy to bend, and it 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 in the extrusion box 8 is sent to the spray plate 83 from the connecting pipe 81 and the No. 1 guide pipe 82, and the spray plate 83 pre-sprays the lubricating oil on the position of the metal plate that needs to be stamped, thereby improving the effect of continuous stamping of the metal plate.

[0031] The sliding frame 12 is fixedly connected to an oil tank 9 on one side close to the extrusion box 8; a No. 2 guide pipe 91 is fixedly connected to the outer wall of the oil tank 9; a one-way valve 92 is threadedly connected to the top of the extrusion box 8, and the one-way valve 92 is connected to the No. 2 guide pipe 91 at the end away from the extrusion box 8; when the extrusion box 8 is filled with oil, the lubricating oil is first stored in the oil tank 9, and the lubricating oil in the oil tank 9 is sent to the one-way valve 92 from high to low, and falls into the extrusion box 8 through the one-way valve 92 to wait for extrusion, which plays the role of filling the extrusion box 8 with oil. When the extrusion rod 51 squeezes the lubricating oil in the extrusion box 8, the one-way valve 92 is set to only enter but not exit, and the lubricating oil squeezed in the extrusion box 8 is sent out from the connecting pipe 81 on one side, which plays the role of controlling the outlet delivery of the lubricating oil in the extrusion box 8. The material of the No. 2 guide pipe 91 is flexible material, and the No. 2 guide pipe 91 can bend and deform when the extrusion box 8 slides down.

[0032] The inner wall of the connecting pipe 81 is fixedly connected with a sealing ring plate 93; the outer wall of the No. 2 guide pipe 91 is fixedly connected with a sealing ball 94 through an elastic pull rope; when the lubricating oil in the extrusion box 8 is squeezed and sprayed, the one-way valve 92 blocks the oil inlet at the top of the extrusion box 8, and the lubricating oil in the extrusion box 8 is squeezed to reach the connecting pipe 81. As the extrusion rod 51 squeezes the lubricating oil in the extrusion box 8, when the pressure is greater than the pulling force of the elastic pull rope, the lubricating oil rushes into the No. 1 guide pipe 82 from between the sealing ball 94 and the sealing ring plate 93 for transportation. When the lubricating oil in the extrusion box 8 is squeezed out, the elastic pull rope on the sealing ring plate 93 pulls the sealing ball 94 to reset and seal the internal channel of the connecting pipe 81, and the one-way valve 92 continues to inject oil into the extrusion box 8, thereby controlling and sealing the inside of the connecting pipe 81.

[0033] Working process: When continuously stamping metal parts, the stamping machine body 1 is used as the main frame of the stamping machine to connect the metal parts, and the protruding parts of the multiple plug-in blocks 14 on the upper mold 15 are slidably inserted into the interior of the fixed block 13, and the plug-in blocks 14 are fixed and limited in the fixed block 13 by relying on the plug-in assembly. The bottom of the upper mold 15 is assembled with multiple stamping blocks. When stamping the metal plate, the long strip of metal plate is placed in the processing groove and intermittently transported below the upper mold 15. The output end of the hydraulic cylinder 11 drives the sliding frame 12 to slide down, and synchronously drives the multiple stamping blocks at the bottom of the upper mold 15 to stamp the metal plate. As the metal plate is intermittently transported, the upper mold 15 continuously stamps the metal plate to achieve multiple shaping. When replacing the upper mold 15, the limit of the multiple plug-in blocks 14 by the plug-in assembly is released, the upper mold 15 is removed, and a different type of upper mold 1 is replaced 5 It is sufficient to plug the plug-in block 14 into the fixed block 13 again to fix it, so that the mold can be quickly replaced, which is convenient for stamping and manufacturing of metal parts of multiple models, thereby improving the production capacity of metal parts; when the upper mold 15 is quickly replaced, the matching slide plate 22 is pressed to slide down the inner wall of the fixed block 13, and the matching slide plate 22 simultaneously drives the plug rod 2 to slide down inside the fixed block 13, and the No. 1 elastic member 21 is pulled and stressed. At this time, the plug rod 2 slides out of the plug-in block 14, and the plug-in block 14 is taken out from the inside of the fixed block 13, and then the old upper mold 15 can be removed, and then the plug-in block 14 on the new upper mold 15 is inserted into the fixed block 13, and the matching slide plate 22 is loosened. The matching slide plate 22 is pulled back by the elastic force of the No. 1 elastic member 21, so that the plug rod 2 passes through the plug-in block 14 and is plugged into the inside of the fixed block 13, which plays a role in quickly replacing the upper mold 15; In order to improve the stamping effect of metal parts, the lower mold 3 is placed in the processing groove and used in conjunction with the upper mold 15. During the process of placing the lower mold 3 at the bottom of the processing groove, the limit rods 31 on both sides of the stamping machine body 1 need to be squeezed to retract into the inside of the stamping machine body 1. The two limit rods 31 synchronously squeeze the No. 1 spring to contract. When the circular holes on both sides of the lower mold 3 correspond to the two limit rods 31, the No. 1 spring elastic force squeezes the limit rod 31 to reset, so that the limit rod 31 is stuck in the circular hole, which plays a role in installing the lower mold 3. When disassembling the lower mold 3, the limit rod 31 is pressed into the stamping machine body. 1, the lower mold 3 can be taken out from the inner wall of the stamping machine body 1; when the lower mold 3 is installed, the lower mold 3 squeezes the support plate 4 and slides down 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 until the two limit rods 31 are inserted into the two round holes of the lower mold 3, and the installation of the lower mold 3 is completed. When the lower mold 3 is replaced according to the matching of the upper mold 15, the limit of the two limit rods 31 on the lower mold 3 is released, and the second spring at the bottom end of the support plate 4 is reset, driving the support plate 4 to lift the lower mold 3 for easy picking, which plays a role in the rapid replacement of the lower mold 3; Before the continuous stamping of the metal plate, since impurities are easily attached to the surface of the metal plate, the residual impurities affect the stamping effect of the metal plate. The fixing frame 5 is installed at the front end of the upper mold 15 by using the connecting assembly, which is located above the feeding part of the processing groove. The shovel block 52 connected to the bottom end of the extrusion rod 51 is attached to the upper end surface of the conveyed metal plate, and the second elastic member 53 is sleeved on the outer wall of the extrusion rod 51 for auxiliary support. As the metal plate is intermittently conveyed, the inclined surface of the shovel block 52 scrapes the surface of the metal plate to reduce the attachment of impurities on the surface of the metal plate and improve the continuous stamping effect of the metal plate. When the fixing frame When the fixing frame 5 is installed at the front end of the upper mold 15, the fixing frame 5 is inserted into the two connecting plates 6, and the two connecting plates 6 enter the interior of the fixing frame 5, and two bolts 61 are used to be threadedly connected to the interior of the fixing frame 5, and the bolts 61 penetrate the connecting plates 6, so as to play the role of fixing the fixing frame 5; when the impurities on the surface of the metal plate are scraped, the scraped impurities remain at the shovel block 52, affecting the scraping effect of the shovel block 52 on the metal plate, relying on the collection groove 7 to collect the scraped impurities, reducing the accumulation of impurities at the shovel block 52, and improving the scraping effect of the shovel block 52 on the impurities on the metal plate; 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 die and the workpiece, reduce friction and wear, and reduce the stamping force and cool and prevent rust. Therefore, the lubricating oil is added to the inside of the extrusion box 8. As the upper die 15 stamps the metal plate, the upper die 15 synchronously drives the fixing frame 5 to squeeze the second elastic member 53 to shrink 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 makes the inside of the extrusion box 8 lubricated. The lubricating oil is squeezed, and the oil inlet at the top of the squeeze box 8 is blocked. The stamped metal plate is not easy to bend, which is enough to support the squeeze rod 51 on the shovel block 52 to squeeze the lubricating oil inside the squeeze box 8. The lubricating oil squeezed in the squeeze box 8 is sent to the spray plate 83 from the connecting pipe 81 and the first guide pipe 82. The spray plate 83 pre-sprays the lubricating oil on the position where the metal plate needs to be stamped, thereby improving the effect of continuous stamping of the metal plate. When the inside of the squeeze box 8 is filled with oil, the lubricating oil is first stored in the oil tank 9, and the lubricating oil in the oil tank 9 is sent from high to low through the second guide pipe 91 to the one-way The one-way valve 92 is located at the bottom of the extrusion box 8, and the ... The oil inlet at the top of the squeeze box 8 is blocked, and the lubricating oil in the squeeze box 8 is squeezed into the connecting pipe 81. As the squeeze rod 51 squeezes the lubricating oil in the squeeze box 8, when the pressure is greater than the pulling force of the elastic pull rope, the lubricating oil rushes into the No. 1 guide pipe 82 from between the sealing ball 94 and the sealing ring plate 93 for transportation. When the lubricating oil in the squeeze box 8 is squeezed out, the elastic pull rope on the sealing ring plate 93 pulls the sealing ball 94 to reset and block the internal channel of the connecting pipe 81, and the one-way valve 92 continues to inject oil into the squeeze box 8, thereby controlling the blockage of the inside of the connecting pipe 81.
