Detailed implementation manner

[0030] Next, in combination with the embodiments of the present utility model Figures 1 - 9 The technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] The present utility model provides a technical solution: a high-speed extruder, including a base 1 and a top seat 2. A number of support columns 3 are connected between the base 1 and the top seat 2. An oil cylinder 4 is fixed on the top seat 2. A connecting block 5 is fixed on the piston rod of the oil cylinder 4. An upper die structure 6 is fixed on the bottom surface of the connecting block 5. A lower die structure 7 is arranged below the upper die structure 6. The lower die structure 7 is fixed on the base 1. A feeding mechanism 8 is arranged on the right side of the lower die structure 7, and a blanking channel 9 is arranged on its left side. During operation, the feeding mechanism 8 sends the metal blank into the lower die structure 6. Then the oil cylinder 4 is started to drive the upper die structure 6 to press down, extruding and forming the metal blank in the lower die structure 7. Then the oil cylinder 4 rises back to its original position. The formed metal part is discharged through the blanking channel 9. At the same time, the feeding mechanism 8 sends the next metal blank into the lower die structure 7 for extrusion and forming. Just like this, it circulates repeatedly to realize continuous and uninterrupted feeding and processing of the metal blank, greatly improving the working efficiency. Among them, this high-speed extruder is mainly applied to the production of bearings.

[0032] The loading mechanism 8 includes a support base 10 fixed on the base 1. The upper surface of the support base 10 is fixed with a first support plate 11 and a second support plate 12. A number of support rods 13 are fixed between the first support plate 11 and the second support plate 12. A slideway 14 is fixed on the support rods 13. The discharge end of the slideway 14 is connected with a receiving plate 15. Above the receiving plate 15, there are a clamping mechanism 16 and a stop mechanism 17. The rear end of the clamping mechanism 16 is fixed on a slide block 18. A lead screw mechanism 19 is arranged on the slide block 18, and the lead screw mechanism 19 is arranged on the support base 10. This is the specific structure of the loading mechanism 8, and its working principle is as follows: Multiple metal blanks are arranged one by one in the slideway 14. There is a metal blank to be loaded left on the receiving plate 15, and the metal blank on the receiving plate 15 cannot move forward due to the stop of the stop mechanism 17. When it is necessary to send the metal blank on the receiving plate 15 into the lower die structure 7, the clamping mechanism 16 is activated to clamp the metal blank on the receiving plate 15. Then, the stop mechanism 17 and the lead screw mechanism 19 are activated simultaneously. While the stop mechanism 17 releases the metal blank on the receiving plate 15, the lead screw mechanism 19 pushes the whole clamping mechanism 16 forward until the metal blank clamped by the clamping mechanism 16 is located above the lower die structure 7. Then, the clamping mechanism 16 releases the metal blank, and the metal blank falls into the lower die structure 7, completing the feeding of one metal blank. Then, the lead screw mechanism 19 brings the clamping mechanism 16 back to its original position. Among them, during the process of the lead screw mechanism 19 sending the metal blank clamped on the clamping mechanism 16 to the lower die structure 7, the lowermost metal blank in the slideway 14 will slide onto the receiving plate 15. At the same time, the stop mechanism 17 is activated to stop the metal blank on the receiving plate 15, waiting to be sent into the lower die structure 7. Just like this, the metal blanks are sent into the lower die structure 7 one by one, realizing automatic continuous loading and greatly improving the working efficiency. The upper end of the slideway 14 can be connected with a vibrating feeder to realize the function of automatically sending metal blanks into the slideway 14.

[0033] The stop mechanism 17 includes a connecting frame 20 fixed between the first support plate 11 and the second support plate 12. The front end of the connecting frame 20 is fixed with a first air cylinder 21. The end of the piston rod of the first air cylinder 21 is fixed with a pressing block. When the stop mechanism 17 needs to stop the metal blank below it, the first air cylinder 21 is activated, and its piston rod extends, driving the pressing block to move downward to press the metal blank. When it is necessary to send the metal blank into the lower die structure 7, the first air cylinder 21 is activated, and its piston rod contracts, causing the pressing block to release the metal blank. A rubber block can be fixed on the bottom surface of the pressing block, so that the metal blank will not be damaged when being pressed and stopped, and the friction is increased to improve the stopping effect.

[0034] The material clamping mechanism 16 includes a fixing plate 22 fixedly connected to the sliding seat 18. A second cylinder 23 is fixed on the fixing plate 22. A T-shaped block 24 is fixed at the end of the second cylinder 23. The T-shaped block 24 is rotatably connected to a first U-shaped block 25. A rotating rod 26 is fixedly penetrated through the first U-shaped block 25. The rotating rod 26 is rotatably connected to two supporting blocks 27. The supporting blocks 27 are fixed on the fixing plate 22. And the first U-shaped block 25 is arranged between the two supporting blocks 27. The end of the rotating rod 26 penetrates out of the supporting block 27. And a part of the rotating rod 26 that penetrates out of the supporting block 27 is fixed with a second U-shaped block 28. The rear end of a pull rod 29 is rotatably connected to the second U-shaped block 28. The front end of the pull rod 29 is rotatably connected to a rotating block 30. The rotating block 30 is rotatably connected to the fixing plate 22. A clamping block 31 is fixed at the front end of the rotating block 30. This is the specific structure of the material clamping mechanism 16. Its working principle is as follows: When it is necessary to clamp the metal blank on the blank receiving plate 15, the second cylinder 23 is started, and its piston rod extends, and then the lower end of the first U-shaped block 25 is pushed forward, so that the upper end of the first U-shaped block 25 drives the rotating rod 26 to rotate backward, and then drives the upper ends of the two second U-shaped blocks 28 to rotate backward. While the upper ends of the second U-shaped blocks 28 rotate backward, the lower ends of the second U-shaped blocks 28 move forward, and then drive the pull rod 29 forward, and then make the two rotating blocks 30 rotate towards each other, and then make the two originally open clamping blocks 31 close up, so as to clamp the metal blank. When it is necessary to loosen the clamped metal blank, the second cylinder 23 is started, and its piston rod contracts to perform the reverse operation.

[0035] The lead screw mechanism 19 includes a motor 32 fixed on the support seat 10. A lead screw 33 is fixed on the output shaft of the motor 32. A nut 34 is arranged on the lead screw 33. The upper surface of the nut 34 is fixed on the bottom surface of the sliding seat 18. The front end of the lead screw 33 is rotatably connected to a fixed seat 35. The fixed seat 35 is fixed on the support seat 10. The forward and backward movement of the whole material clamping mechanism 16 is realized through the lead screw mechanism 19.

[0036] The lower die structure 7 includes a backing plate 36 fixed on the base 1. A lower die base 37 is fixed on the backing plate 36. The lower die base 37 is detachably connected with a lower die 39 through a plurality of hydraulic clamping devices 38. A third cylinder 40 is arranged below the backing plate 36. A knockout rod 41 is fixed on the piston rod of the third cylinder 40. A groove for fixing the third cylinder 40 is formed on the base 1. Through holes 42 for the up-and-down movement of the knockout rod 41 are formed on the backing plate 36, the lower die base 37 and the lower die 39. The metal blank is placed in the lower die 39. After the metal blank is extruded, the third cylinder 40 is started. Its piston rod extends to drive the knockout rod 41 upward. The knockout rod 41 jacks up the extruded metal blank in the lower die 39 until the bottom surface of the metal blank is higher than the lower die 39. Then, a blowing mechanism blows the metal blank onto the blanking channel 9. The blowing mechanism includes an air pump and two air pipes communicated with the air pump. The air pump and the air pipes can be fixed on the connecting frame 20. The blowing ports of the two air pipes are aligned with the rear side of the metal blank jacked up by the knockout rod 41. The air pressure for blowing the metal blank is about 0.7 MPa. Through the setting of this structure, automatic blanking is realized, and the working efficiency is further improved. Two opposite induction sensors can be arranged in the blanking channel 9 to detect whether the product comes out of the blanking channel 9. The hydraulic clamping devices 38 can be set to four. Through this setting, automatic clamping and fixing and loosening of the lower die 39 are realized, which greatly facilitates the installation and replacement of the lower die 39.

[0037] The hydraulic clamping device 38 includes a first fixing block 43 fixed on the lower die base 37. A hydraulic cylinder is arranged in the first fixing block 43. The end of the piston rod of the hydraulic cylinder is fixed with a clamping block 44. The clamping block 44 is rotatably connected to an ear seat 45. The ear seat 45 is fixed on a second fixing block 46. When the lower die 39 needs to be replaced, the hydraulic cylinder in the first fixing block 43 is started. Its piston rod contracts to pull down the end of the clamping block 44 away from the lower die 39, so that the end of the clamping block 44 clamping the lower die 39 moves upward, thus loosening the lower die 39. Then, the lower die 39 is taken out and a new one is replaced. Then, the hydraulic cylinder in the first fixing block 43 is restarted. Its piston rod extends to make the clamping block 44 clamp the lower die 39, and the replacement is completed. It is not only convenient but also greatly improves the replacement efficiency.

[0038] The upper die structure 6 includes an upper die base 47 fixed to the bottom surface of the connecting block 5. The upper die 48 is detachably connected to the upper die base 47 through two hydraulic clamping devices 38. Two mounting notches 49 are provided on the upper die 48. When it is necessary to disassemble the upper die 48, just loosen the hydraulic clamping device 38 until the upper die 48 can rotate. At this time, the hydraulic clamping device 38 still supports the upper die 48 to prevent it from falling. Then rotate the upper die 48 so that the two mounting notches 49 are exactly aligned with the clamping blocks 44 of the two hydraulic clamping devices 38, and the upper die 48 can be removed. When it is necessary to install, just perform the reverse operation. Through the settings of the hydraulic clamping device 38 and the mounting notch 49, not only is the replacement of the upper die 48 greatly facilitated, but also the safety of replacing the upper die 48 is ensured.

[0039] There are four support columns 3, which are respectively connected between the four pairs of opposite corners of the base 1 and the top seat 2. The connecting block 5 is slidably connected to the support column 3. The sliding connection between the connecting block 5 and the support column 3 plays a good role in guiding and limiting, and at the same time improves the overall stability.

[0040] The oil cylinder 4 is connected to a hydraulic station 50. The hydraulic station 50 is fixed on the support frame 51. A control cabinet 52 and an oil cooler 53 are provided below the hydraulic station 50. This setting plays a good role in saving space. Among them, through the setting of the oil cooler 53, the hydraulic oil in the hydraulic station 50 is cooled well to prevent the oil temperature from being too high and realize unattended supervision.

[0041] Working principle: During operation, metal blanks are arranged one by one in the slideway 14. There is a metal blank to be loaded on the receiving plate 15, and the metal blank on the receiving plate 15 cannot move forward due to the blocking of the blocking mechanism 17. When it is necessary to send the metal blank on the receiving plate 15 into the lower die structure 7, the clamping mechanism 16 is activated to clamp the metal blank on the receiving plate 15. Then the blocking mechanism 17 and the lead screw mechanism 19 are activated at the same time. While the blocking mechanism 17 releases the metal blank on the receiving plate 15, the lead screw mechanism 19 pushes the clamping mechanism 16 forward as a whole until the metal blank clamped by the clamping mechanism 16 is located above the lower die structure 7. Then the clamping mechanism 16 releases the metal blank, and the metal blank falls into the lower die structure 7, completing the feeding of a metal blank. Then the lead screw mechanism 19 brings the clamping mechanism 16 back to its original position. Among them, during the process of the lead screw mechanism 19 sending the metal blank clamped on the clamping mechanism 16 into the lower die structure 7, the lowermost metal blank in the slideway 14 will slide onto the receiving plate 15, and at the same time the blocking mechanism 17 is activated to block the metal blank on the receiving plate 15 and wait to be sent into the lower die structure 7. Just like this, the metal blanks are sent into the lower die structure 7 one by one, realizing automatic continuous feeding and greatly improving the working efficiency.
