[0041] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] refer to Figure 1The utility model provides an automatic cutting device for container foot castings, which comprises a machine base 1 on which a casting clamping mechanism 2 and a cutting mechanism 3 are arranged.

[0043] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 The casting clamping mechanism 2 includes a rotating bracket 21 rotatably arranged on the machine base 1 and a loading station 22, a first cutting station 23, a second cutting station 24 and a blanking station 25 arranged in sequence along the circumference of the rotating bracket 21. The rotating bracket 21 rotates circumferentially under the action of the driving mechanism; the loading station 22, the first cutting station 23, the second cutting station 24 and the blanking station 25 are all provided with a positioning assembly 4 for fixing the casting 5. The positioning assembly 4 includes a positioning seat 41 for supporting the casting 5 and a clamping member 42 arranged on both sides of the positioning seat 41 in the width direction. The clamping member 42 cooperates with the positioning seat 41 to fix the casting 5.

[0044] Among them, reference Figure 1 , Figure 2 , Figure 3 and Figure 5 The rotating bracket 21 is arranged in a cross shape, and a reinforcing rib 6 is arranged between adjacent workstations. The rotating bracket 21 of this structure has a small overall weight, and the rotating bracket 21 rotates more flexibly during operation; the reinforcing rib 6 increases the strength and firmness of the rotating bracket 21 of this structure.

[0045] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 The pressing member 42 includes a pressing link group 421 and a driving member 422; the pressing link group 421 includes a pressing rod 4211 hinged at one end on the side of the positioning seat 41 and a pressing rod 4212 vertically arranged at the other end of the pressing rod 4211; the driving member 422 includes a fixed seat 4221 arranged on the machine base 1 and a driving cylinder 4222 hinged on the fixed seat 4221, and the telescopic end of the driving cylinder 4222 is vertically hinged on the pressing rod 4212. When the casting 5 is placed on the positioning seat 41, the pressing link group 421 is driven to rotate by the driving cylinder 4222, so that the pressing rod 4212 is pressed against the upper end surface of the casting 5. At this time, the positioning seat 41 and the pressing member 42 realize the upper and lower direction limit fixation of the casting 5. When the material head in the casting 5 is cut later, the casting 5 is not easy to move.

[0046] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5There are two groups of clamping link groups 421, and a connecting rod 7 is hinged between the clamping rods 4212 in the two clamping link groups 421, and the telescopic end of the driving cylinder 4222 is hinged on the connecting rod 7; when the driving cylinder 4222 drives the clamping link group 421 to rotate, the two clamping link groups 421 are guaranteed to move synchronously under the action of the connecting rod 7; at the same time, it can also increase the pressure covering area of ​​the casting 5, so that the casting 5 can be more firmly installed on the positioning seat 41.

[0047] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 A sensing block 8 cooperating with the connecting rod 7 is arranged on the side of the positioning seat 41 and between the two clamping rods 4212. The sensing block 8 is used to detect whether the clamping rod 4212 is pressed on the casting 5. When the clamping rod 4212 is pressed on the upper end surface of the casting 5, the lower end surface of the connecting rod 7 is pressed against the sensing block 8, thereby triggering the sensing block 8. The sensing block 8 detects and feeds back that the clamping member 42 has achieved the fixing of the pressure cover on the casting 5.

[0048] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 The positioning seat 41 is vertically provided with a debris blocking plate 10 along the inner side end in the length direction. When the material head on the casting 5 is cut, the debris blocking plate 10 plays a blocking role to prevent the debris generated by the cutting from splashing everywhere. A material head tray 11 is provided below the positioning seat 41 on the rotating bracket 21, and a material drop notch 12 connected to the material head tray 11 is provided on the positioning seat 41. After cutting, the material head 51 falls into the material head tray 11 under the action of its own gravity, realizing the separation of the casting 5 and the material head 51, which is convenient for the separation and collection of the cut casting 5 and the material head 51.

[0049] refer to Figure 1 and Figure 4, two cutting mechanisms 3 are provided, and the two cutting mechanisms 3 are fixed on the machine base 1 along the circumference of the rotating bracket 21. One of the cutting mechanisms 3 is located at the first cutting station 23, and the other cutting mechanism 3 is located at the second cutting station 24. The casting 5 is cut twice by the two cutting mechanisms 3, so that the material head 51 in the casting 5 is cut off. Specifically, the cutting mechanism 3 includes a fixing frame 31 vertically arranged on the machine base 1, a rocker arm 32 hinged at the top of the fixing frame 31, a cutting head 34 with a cutter disc 33, and a driving motor 35 for the cutter disc 33 to work. The output end of the driving motor 35 is connected to the cutting head 34 through a transmission belt, thereby driving the cutter disc 33 to rotate. The cutter disc 33 is a disc-shaped serrated cutter disc. The rocker arm 32 points to the rotating bracket 21 in the radial direction of the rotating bracket 21, the cutting head 34 with a cutter disc 33 is arranged on the upper end surface of the radial inner end of the rocker arm 32, the driving motor 35 is arranged on the upper end surface of the radial outer end of the rocker arm 32, and the lower end surface of the radial outer end of the rocker arm 32 is hinged with a rotating cylinder 36 that drives the rocker arm 32 to rotate, and the end of the rotating cylinder 36 away from the telescopic end is hinged on the machine base 1.

[0050] refer to Figure 1-Figure 5 When working, the casting 5 to be cut is placed on the positioning seat 41 of the loading station 22, and the driving mechanism drives the rotating bracket 21 to rotate 90° clockwise to rotate the casting 5 to the first cutting station 23. At this time, the pressing member 42 presses and covers the casting 5 to fix the casting 5, and the first cutting of the casting 5 is achieved through the cutting mechanism 3;

[0051] After the first cutting of the casting 5 is completed, the rotating bracket 21 continues to rotate 90° clockwise, and the casting 5 after the first cutting is rotated to the second cutting station 24, and the slug 51 is cut for the second time by another cutting mechanism 3, so that the slug 51 is cut off from the casting 5, and the slug 51 falls into the slug tray 11 under its own gravity;

[0052] Finally, the rotating bracket 21 continues to rotate clockwise by 90° to rotate the casting 5 after the cutting of the material head 51 to the unloading station 25, the pressing member 42 is released, and the casting 5 and the material head 51 are taken out at the unloading station 25, thereby realizing the cutting of the material head of the casting 5. In the working process, each time the rotating bracket 21 rotates 90°, the loading and unloading are performed at the loading station 22 and the unloading station 25.
