Description

Technical Field

[0001] The invention relates to the technical field of die casting slag bag grinding, and in particular to a large-scale integrated die casting slag bag automatic removal device. Background Art

[0002] Die casting slag refers to the small bubbles or holes on the surface of the casting caused by some light impurities due to the instability of the metal fluid flow and the cooling effect on the inside during the die casting process. These small holes are like a small bag that can hold some granular slag impurities, so they are called "slag".

[0003] After die-casting is completed, the slag needs to be removed from the die-casting. The traditional way to remove the slag is to manually remove it with tools such as hammers and scrapers. Although this method is simple to operate, it has low removal efficiency and is prone to accidentally damaging the surface of the die-casting. In addition, the labor intensity is high and it is easy to get tired. Although there is a method in the existing technology to remove the slag manually with the help of stamping equipment, which can effectively improve the efficiency of slag removal, it requires precise control of the operating force and position, and has certain requirements for the skills and experience of the operator. Improper operation may cause equipment damage or incomplete slag removal. There may be pressure damage to the surface of the die-casting during the stamping process. Moreover, for die-cast auto parts with complex local structures, ordinary stamping equipment cannot remove the slag at all.

[0004] The existing patent discloses an automatic slag bag removal machine for die castings (CN117415301A), which uses a frame, a workbench, a bearing boss, a punching mechanism, a cutting mechanism, a hydraulic slag bag removal device and a slag bag collection vehicle.

After the die casting is placed on the placing truncated table 13, the die casting can be rotated to adjust the grinding angle of the grinding paste, and the moving distance of the placing table can be changed to adjust the grinding distance of the die casting.

[0042] Example 2

[0043] A rotating column 18 is fixedly connected to the lower part of the rotating platform 12, and the rotating platform 12 is rotatably connected to the base 1 through the rotating column 18. A rectangular through groove is provided inside the rotating column 18, and limit plates 38 are installed on the upper and lower sides of the inner part of the rectangular through groove. An extrusion U ring 32 that can move up and down is sleeved on the upper limit plate 38; a pair of connecting blocks 33 are fixedly connected to the bottom end of the placing truncated table 13, and a brake rod 34 is fixedly connected to the connecting block 33, wherein the brake rod 34 passes through the extrusion U ring 32 (such as Figure 6 , 7 As shown), when the U-ring 32 is squeezed and moved downward, the brake rod 34 will be squeezed. Since the brake rod 34 is fixedly connected to the placement table 13, the moving distance of the placement table 13 can be fixed.

[0044] The lower limiting plate 38 is provided with a rotatable rotating shaft 21, and the top of the rotating shaft 21 passes through the extrusion U ring 32 to the top of the limiting plate 38; the surface of the rotating shaft 21 is provided with a spiral groove 40, and the bottom end of the extrusion U ring 32 includes a circular ring for sleeved rotating shaft 21, and the surface of the circular ring is provided with a plug-in column 39, wherein the inner end of the plug-in column 39 is clamped in the inner part of the spiral groove 40.

[0045] Example 3

[0046] The surface of the stand 2 is provided with a side frame 9, and a driving shaft 23 is provided inside the side frame 9, and a transmission disk 8 is sleeved on the left end of the driving shaft 23; a driving motor 6 is installed on the surface of the base 1 and close to the side frame 9, and a belt 7 is sleeved between the output shaft of the driving motor 6 and the transmission disk 8. One end of the screw rod 4 passes through the inside of the side frame 9 and is sleeved with a right-angle gear 27, and a transmission gear 24 is sleeved on the surface of the driving shaft 23 inside the side frame 9. The transmission gear 24 specifically includes a left gear 2401 and a right gear 2402, wherein the left gear 2401 and the right gear 2402 are provided with engaging teeth 25 on the corresponding sides, and the transmission gear 24 and the engaging teeth 25 are both in rotational contact with the driving shaft 23, and the left gear 2401 and the right gear 2402 are respectively meshed and connected with the left and right ends of the right-angle gear 27 (such as Figure 8 As shown), when the left gear 2401 is used as a driving wheel, it can drive the right-angle gear 27 to rotate clockwise, and when the right gear 2402 is used as a driving wheel, it can drive the right-angle gear 27 to rotate counterclockwise.

[0047] A swinging tooth column 26 is sleeved on the surface of the driving shaft 23 and located between the left gear 2401 and the right gear 2402. The left and right sides of the swinging tooth column 26 are provided with teeth that cooperate with the engaging teeth 25. A sliding groove 28 is provided in the middle of the driving shaft 23. A pin 31 is provided inside the swinging tooth column 26, wherein the pin 31 passes through the sliding groove 28. An electric telescopic rod 10 is fixedly mounted on the surface of the side frame 9. A limiting groove 45 is also provided on the surface of the side frame 9. A sleeve 44 is provided on the quick-release shaft sleeve of the electric telescopic rod 10. The other end of the sleeve 44 passes through the limiting groove 45 and penetrates into the inside of the side frame 9 and is rotatably sleeved on the swinging tooth column 26. When the electric telescopic rod 10 squeezes the swinging tooth column 26 to cooperate with the engaging teeth 25 on the right gear 2402, only the right gear 2402 rotates and drives the right-angle gear 27 to rotate counterclockwise, and the counterclockwise rotation of the screw rod 4 can drive the swinging platform 5 to move to the other side.

[0048] Example 4

[0049] A fixing ring 29 is provided on the right side of the side frame 9. The right end of the drive shaft 23 passes through the inside of the fixing ring 29 and is sleeved with a winding ring 30. A plurality of friction springs 43 are provided inside the winding ring 30. The other end of the friction springs 43 is in pressure contact with the surface of the drive shaft 23. A cable 11 is connected below the fixing ring 29. The cable 11 includes an outer rubber and an inner iron cable. The inner iron cable at one end of the cable 11 is wound on the winding ring 30. A lower vertical plate 15 is provided below the base 1. A return spring 16 is provided between the lower vertical plate 15 and the baffle 46. The iron cable at the other end of the cable 11 passes through the lower vertical plate 15 and the return spring 16 and is connected to the baffle 46.

[0050] The working principle of the present invention is as follows: after the die casting to be deslugged is placed on the placing truncated table 13 (such as Figure 2 As shown), the rotating table 12 is rotated until one end faces the polishing paste 14, and then the die casting is pushed to move toward the polishing paste 14, wherein the round table 13 can move along the slide bar 36 (as shown in FIG. Figure 7 shown).

[0051] When the die casting is in contact with the polishing paste 14, the drive motor 6 is started, and the drive motor 6 drives the drive shaft 23 to rotate through the belt 7 and the transmission disc 8 (such as Figure 8 , 9 As shown), the swinging gear column 26 on the transmission shaft 23 will rotate under the drive of the pin 31 and the sliding groove 28 (as shown in FIG. Figure 5 shown).

[0052] When the electric telescopic rod 10 squeezes the swinging gear column 26 through the sleeve 44 until it matches with the engaging tooth 25 on the left gear 2401 (such as Figure 5 , 8 As shown in the figure, only the left gear 2401 rotates and drives the right-angle gear 27 to rotate clockwise, thereby driving the screw 4 to rotate clockwise, and the clockwise rotation of the screw 4 can drive the swing table 5 to move to one side. Similarly, when the electric telescopic rod 10 squeezes the swing gear column 26 to cooperate with the engaging tooth 25 on the right gear 2402, only the right gear 2402 rotates and drives the right-angle gear 27 to rotate counterclockwise, and the counterclockwise rotation of the screw 4 can drive the swing table 5 to move to the other side. By driving the reciprocating swing of the polishing paste 14 by the swing table 5, the slag bag at the edge of the die casting can be polished and removed.

[0053] During the rotation of the drive shaft 23, the friction spring 43 drives the winding ring 30 to rotate (eg Figure 5 , 8 As shown), the winding ring 30 can be driven to rotate to wind the iron rope in the cable 11 (because the rotation direction of the drive shaft 23 will never change, the drive shaft 23 will be started to wind the iron rope, and the drive shaft 23 will stop rotating and stop winding the iron rope. Moreover, when the iron rope can no longer be wound, the contact state between the friction spring 43 and the drive shaft 23 changes from a static friction state to a sliding friction state), so that the other end of the iron rope in the cable 11 will overcome the elastic force of the reset spring 16 to pull the baffle 46 (as shown in FIG. Figure 4 , 6 As shown), the extrusion steel belt 19 will be pulled to compress the extrusion rack 20 and the transmission column 18.

[0054] The transmission column 18 is squeezed, so that the rotation angle of the rotating table 12 can be locked, thereby ensuring that the die casting placed on the round table 13 can be fixed at a grinding angle. The squeezing of the squeezing rack 20 drives the lower gear 22 to rotate (such as Figure 4As shown in the figure, the lower gear 22 will drive the squeezing U ring 32 to move downward through the spiral groove 40 on the rotating shaft 21 and the plug-in column 39 on the squeezing U ring 32, so that the squeezing U ring 32 can squeeze the brake rod 34, thereby locking the forward extension distance of the placement table 13.

[0055] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
