Description

Technical Field

[0001] This utility model relates to the field of obstetrics and gynecology technology, and in particular to a bending and forming machine for an internal toothed ring support. Background Technology

[0002] An internal gear ring support is a mechanical structural component used to fix and support the internal gear ring and ensure its precise fit with other transmission components. During the production and processing of internal gear ring supports, a bending process is usually required, and a bending machine is typically used for this process.

[0003] A Chinese utility model patent application, CN219443122U, discloses a bending mechanism for a bending machine, comprising: a bending box mounted on the top of a base; a controller mounted on one side surface of the bending box; side plates mounted on both sides of the top of the bending box; a top plate mounted between the two side plates; and second electric push rods mounted on both sides of the bottom of the top plate. The beneficial effect is that the first electric push rod can drive a support rod to move, allowing the support rod to rotate inside a rotating shaft seat. Simultaneously, the rotating shaft seat synchronously drives the bending plate to move, causing the bending plate to rotate at a fixed point via the rotating shaft. This allows for adjustment of the bending plate's angle and the angle between the two bending plates, enabling adjustment of the angle between the two bending plates according to the required bending angle of the workpiece, thus accommodating different bending angles.

[0004] Referring to the bending mechanism of the aforementioned bending machine, during the bending process, the bent workpiece accumulates in the "V"-shaped groove formed by the two bending plates, making automatic unloading difficult and requiring manual assistance. This increases the risk to workers and makes unloading inconvenient. Therefore, how to automatically unload and collect the bent internal gear ring support is a crucial issue that needs to be addressed in the design of an internal gear ring support bending forming machine. Utility Model Content

[0005] This utility model provides an internal gear ring bracket bending forming machine to solve the problem of inconvenient material feeding in bending machines.

[0006] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0008] A bending structure is provided on top of the bending die of the internal gear ring support;

[0009] A blanking structure is provided on the bending die of the internal gear ring bracket, and the blanking structure assists the internal gear ring bracket bending die in blanking.

[0010] A limiting structure is provided on the feeding structure.

[0011] Preferably, four support legs are fixedly connected to the bottom side wall of the processing table, an "L"-shaped support frame is fixedly connected to the top side wall of the processing table, a support plate is fixedly connected between the four support legs, and a buffer pad is fixedly connected to the top side wall of the support plate.

[0012] In this technical solution, the buffer pad can cushion and protect the falling material feeding structure.

[0013] Preferably, a collection box is fixedly connected to the left side wall of the processing table, the top side wall of the collection box is flush with the top side wall of the processing table, a shielding frame is fixedly connected to the top side wall of the collection box, and the side walls of the shielding frame are fixedly connected to both sides of the bending mold of the internal gear ring bracket.

[0014] In this technical solution, the collection box can collect the bent internal gear ring bracket, and the shielding frame blocks the rolling internal gear ring bracket, preventing the bent internal gear ring bracket from falling into the collection box properly.

[0015] Preferably, the bending mold of the internal gear ring bracket has a bending groove on its side wall, and the side wall of the internal gear ring bracket bending mold near the shielding frame is arranged in an arc shape.

[0016] Preferably, the bending structure includes a hydraulic cylinder, a push plate, and a bending block. The hydraulic cylinder is fixedly connected to the top inner wall of the support frame, the push plate is fixedly connected to the bottom of the hydraulic cylinder, and the bending block is fixedly connected to the bottom of the push plate.

[0017] Preferably, the bending block faces the bending groove, and the bending block and the bending groove cooperate with each other.

[0018] In this technical solution, the hydraulic cylinder pushes the push plate down, so that the push plate drives the bending pressure block down through the baffle plate, presses the internal gear ring bracket, and performs bending processing on the internal gear ring bracket in conjunction with the bending groove.

[0019] Preferably, the feeding structure includes a pusher block, a push rod, a connecting plate, a first connecting rod, a top rod, a sliding sleeve, a spring, and a sliding rod. The pusher block is slidably connected to the side wall of the processing table. The push rod is fixedly connected to the bottom side wall of the pusher block. The connecting plate is fixedly connected to the bottom side wall of the push rod. The first connecting rod is fixedly connected to the side wall of the connecting plate. The first connecting rod is slidably connected to the side wall of the processing table and the bending die of the internal gear ring bracket. The top of the first connecting rod is fixedly connected to the sliding rod. A sliding sleeve is slidably connected to the sliding rod. A spring is fixedly connected between the sliding sleeve and the first connecting rod. The top of the sliding sleeve is fixedly connected to the top of the sliding sleeve.

[0020] In this technical solution, the connecting rod rises, causing the connecting plate to rise, the connecting plate to rise, the pushing rod to rise, the pushing rod to rise, and the pushing block to rise, which in turn causes the bent internal gear ring bracket to rise.

[0021] Preferably, the pusher block and the bending groove cooperate with each other, and the top of the pusher block is inclined towards one side of the shielding frame.

[0022] In this technical solution, the pusher block can slide within the bending groove.

[0023] Preferably, a fixing block is fixedly connected to the side wall of the connecting rod one near the push plate, and a baffle plate is fixedly connected between the fixing blocks one. The distance between the connecting rod one and the push plate is greater than the length of the fixing block one.

[0024] In this technical solution, the push plate and the fixed block one do not interfere with each other.

[0025] Preferably, the limiting structure includes a second fixed block, a second connecting rod, a limiting rod, and a stop block. The second fixed block is fixedly connected to the side wall of the sliding sleeve. One end of the second connecting rod is rotatably connected between the second fixed blocks. The other end of the second connecting rod is rotatably connected to the limiting rod. The limiting rod is slidably connected to the side wall of the first connecting rod. The bottom of the limiting rod is attached to the top of the first fixed block. Two stop blocks are fixedly connected to the side of the limiting rod.

[0026] In this technical solution, the distance between the sliding sleeve and the first connecting rod is reduced, and the second connecting rod will rotate to push the limiting rod outward, so that the limiting rod leaves the top of the baffle and retracts into the side wall of the first connecting rod, no longer restricting the rotation of the baffle, and the baffle can rotate upward.

[0027] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0028] The positive and progressive effects of this utility model are as follows:

[0029] 1. The hydraulic cylinder drives the push plate to rise. When the push plate passes the baffle plate, it pushes the baffle plate to rise. The baffle plate drives the pusher block to rise. The pusher block drives the bent internal gear ring bracket to rise. When the bottom side wall of the pusher block extends to the top of the bending groove, the bent internal gear ring bracket is completely pushed out of the bending groove. The pushed internal gear ring bracket rolls down the inclined side wall of the pusher block towards the collection box. The baffle block blocks the rolling internal gear ring bracket, which facilitates the automatic unloading and collection of the bent internal gear ring bracket.

[0030] 2. When the top of the pusher block of this application extends to the top of the bending groove, the top of the pusher rod abuts against the side wall of the support frame. The hydraulic cylinder continues to rise, driving the pusher to continue rising. The pusher rod is restricted by the support frame and cannot move. The distance between the sliding sleeve and the first connecting rod decreases, and the second connecting rod will rotate, pushing the limiting rod to move outward, leaving the top of the baffle and retracting into the side wall of the first connecting rod. It no longer restricts the rotation of the baffle. The baffle rotates upward, and the entire unloading structure loses its upward thrust. It falls under its own gravity and returns to its original position, which facilitates the unloading structure to automatically return to its original position after unloading the internal gear ring bracket after bending.

[0038] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0039] like Figure 1-5 As shown, an internal gear ring bracket bending forming machine includes a processing table 1, on which an internal gear ring bracket bending die 5 is fixedly connected. The machine also includes:

[0040] The bending structure 7 is disposed on the top of the bending mold 5 of the internal gear ring bracket;

[0041] The material feeding structure 9 is set on the bending die 5 of the internal gear ring bracket and assists the internal gear ring bracket bending die 5 in material feeding.

[0042] A limiting structure 10 is provided on the feeding structure 9.

[0043] Four support legs 2 are fixedly connected to the bottom side wall of the processing table 1, and an "L"-shaped support frame 6 is fixedly connected to the top side wall of the processing table 1. A support plate 11 is fixedly connected between the four support legs 2, and a buffer pad 12 is fixedly connected to the top side wall of the support plate 11.

[0044] The buffer pad 12 can cushion and protect the falling material feeding structure 9.

[0045] A collection box 3 is fixedly connected to the left side wall of the processing table 1. The top side wall of the collection box 3 is flush with the top side wall of the processing table 1. A shielding frame 4 is fixedly connected to the top side wall of the collection box 3. The side walls of the shielding frame 4 are fixedly connected to the two sides of the bending mold 5 of the internal gear ring bracket.

[0046] Collection box 3 can collect the bent internal gear ring bracket, and the shielding frame 4 can block the rolling internal gear ring bracket to prevent it from falling into the collection box 3 properly.

[0047] The bending mold 5 for the internal gear ring bracket has a bending groove 8 on its side wall, and the side wall of the internal gear ring bracket bending mold 5 near the shielding frame 4 is arranged in an arc shape.

[0048] The bending structure 7 includes a hydraulic cylinder 701, a push plate 702, and a bending block 703. The hydraulic cylinder 701 is fixedly connected to the top inner wall of the support frame 6. The bottom of the hydraulic cylinder 701 is fixedly connected to the push plate 702, and the bottom of the push plate 702 is fixedly connected to the bending block 703.

[0049] The bending block 703 is directly opposite the bending groove 8, and the bending block 703 and the bending groove 8 cooperate with each other.

[0050] The hydraulic cylinder 701 pushes the push plate 702 down, so that the push plate 702 drives the bending block 703 down through the baffle plate 912, pressing the internal gear ring bracket, and cooperating with the bending groove 8 to perform bending processing on the internal gear ring bracket.

[0051] The feeding structure 9 includes a pusher block 901, a push rod 902, a connecting plate 903, a first connecting rod 904, a top rod 905, a sliding sleeve 906, a spring 907, and a sliding rod 908. The pusher block 901 is slidably connected to the side wall of the processing table 1. The push rod 902 is fixedly connected to the bottom side wall of the pusher block 901. The connecting plate 903 is fixedly connected to the bottom side wall of the push rod 902. The first connecting rod 904 is fixedly connected to the side wall of the connecting plate 903. The first connecting rod 904 is slidably connected to the side wall of the processing table 1 and the internal gear ring support bending mold 5. The top of the first connecting rod 904 is fixedly connected to the sliding rod 908. The sliding sleeve 906 is slidably connected to the sliding rod 908. The spring 907 is fixedly connected between the sliding sleeve 906 and the first connecting rod 904. The top of the sliding sleeve 906 is fixedly connected to the top rod 905.

[0052] The connecting rod 904 rises, causing the connecting plate 903 to rise. The connecting plate 903 then causes the push rod 902 to rise. The push rod 902 then causes the pusher block 901 to rise. The pusher block 901 then causes the bent internal gear ring bracket to rise.

[0053] The pusher block 901 and the bending groove 8 cooperate with each other, and the top of the pusher block 901 is inclined towards one side of the shielding frame 4.

[0054] The pusher block 901 can slide within the bending groove 8.

[0055] A fixing block 911 is fixedly connected to the side wall of the connecting rod 904 near the push plate 702. A baffle plate 912 is fixedly connected between the fixing blocks 911. The distance between the connecting rod 904 and the push plate 702 is greater than the length of the fixing block 911.

[0056] This ensures that the push plate 702 and the fixed block 911 do not interfere with each other.

[0057] The limiting structure 10 includes a second fixing block 1001, a second connecting rod 1002, a limiting rod 1003, and a stop block 1004. The second fixing block 1001 is fixedly connected to the side wall of the sliding sleeve 906. One end of the second connecting rod 1002 is rotatably connected between the second fixing blocks 1001. The other end of the second connecting rod 1002 is rotatably connected to the limiting rod 1003. The limiting rod 1003 is slidably connected to the side wall of the first connecting rod 904. The bottom of the limiting rod 1003 is attached to the top of the first fixing block 911. Two stop blocks 1004 are fixedly connected to the side of the limiting rod 1003.

[0058] As the distance between the sliding sleeve 906 and the connecting rod 904 decreases, the connecting rod 1002 rotates, pushing the limiting rod 1003 outward. This causes the limiting rod 1003 to leave the top of the baffle 912 and retract into the side wall of the connecting rod 904, thus no longer restricting the rotation of the baffle 912. The baffle 912 can then rotate upward.

[0059] In use, the electrical components mentioned in this application are all externally connected to a power supply and control switch. The internal gear ring bracket that needs to be bent is placed on the bending groove 8 of the internal gear ring bracket bending mold 5. The hydraulic cylinder 701 pushes the push plate 702 down. When the push plate 702 passes the baffle plate 912, the baffle plate 912 will rotate downward under the push of the push plate 702, so that the push plate 702 drives the bending pressure block 703 down through the baffle plate 912, pressing the internal gear ring bracket, and bending the internal gear ring bracket in conjunction with the bending groove 8.

[0060] After the bending process is completed, the hydraulic cylinder 701 drives the push plate 702 to rise, the push plate 702 drives the bending pressure block 703 to rise, when the push plate 702 passes the baffle plate 912, the baffle plate 912 is restricted by the limiting rod 1003 and cannot move upward, so the push plate 702 pushes the baffle plate 912 to rise synchronously, the baffle plate 912 drives the connecting rod 904 to rise, the connecting rod 904 drives the connecting plate 903 to rise, the connecting plate 903 drives the push rod 902 to rise, the push rod 902 drives the pusher block 901 to rise, and the pusher block 901 drives the internal gear ring bracket after bending to rise;

[0061] When the top of the pusher block 901 extends to the top of the bending groove 8, the top of the push rod 905 abuts against the side wall of the support frame 6. The hydraulic cylinder 701 continues to rise, driving the pusher block to continue rising. At this time, the push rod 905 is restricted by the support frame 6 and cannot move. The sliding rod 908 slides into the sliding sleeve 906, the spring 907 is compressed, the distance between the sliding sleeve 906 and the connecting rod 1 904 is reduced, and the connecting rod 2 1002 will rotate to push the limiting rod 1003 to move outward. When the bottom side wall of the pusher block 901 extends to the top of the bending groove 8, the bending internal gear ring bracket is completely pushed out and rolls down along the inclined side wall of the pusher block 901 toward the collection box 3. The shielding frame 4 shields the rolling internal gear ring bracket to prevent the bending internal gear ring bracket from falling into the collection box 3 properly.

[0062] The limiting rod 1003 retracts from the top of the baffle plate 912 and into the side wall of the connecting rod 904, no longer restricting the rotation of the baffle plate 912. The baffle plate 912 rotates upward, and the pushing plate 702 can no longer push the baffle plate 912 upward. The unloading structure 9 loses its upward thrust and falls back to its original position under its own gravity. The pushing block 901 returns to the bottom of the bending groove 8. The buffer pad 12 can buffer and protect the falling unloading structure 9, which can better enable the unloading structure 9 to automatically return to its original position after unloading the internal gear ring bracket after bending.

[0063] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
