[0001] The invention relates to the field of bending equipment, in particular to an automatic positioning ton barrel metal rod bending equipment. Background Art

[0002] The outer frame of the ton barrel requires multiple rounded rectangular metal rods, which are welded together with straight rods to form the outer frame. The rounded rectangular metal rods are processed using bending equipment.

[0004] However, the above technical solution has the following shortcomings: when bending the metal rod, only one corner can be bent at a time. If it is used to bend the metal rod of the ton barrel frame, in order to obtain a rounded rectangular metal rod, it needs to be bent four times. Each bending requires time-consuming repositioning, resulting in low bending efficiency of the metal rod. Summary of the Invention

DETAILED DESCRIPTION

[0021] Example 1, as Figures 1-6 As shown, the embodiment proposes an automatic positioning ton barrel metal rod bending equipment, which includes a processing table 1, a pressure rod assembly, a pushing assembly and a driving mechanism.

[0022] The processing table 1 is provided with four fixed shafts in a rectangular array. The four fixed shafts are fixedly arranged. The four fixed shafts are respectively the two shafts 1 2 in the back row and the two shafts 2 201 in the front row. The four fixed shafts are rotatably provided with wheels 3. The four wheels 3 are respectively used for bending and positioning the four corners of the rounded rectangular metal rod. A plurality of legs 23 are provided at the bottom of the processing table 1. The four corners of the processing table 1 are rounded to prevent interference with the pressure rod assembly, which is safer. The rear end of the processing table 1 has an extension plate portion. When the metal rod is initially placed, the extension plate portion expands the supporting range. If the worker does not place the metal rod in place, the metal rod may slide onto the extension plate portion, thereby preventing it from falling to the ground.

[0023] like Figures 1-4 As shown, two groups of pressure rod assemblies are symmetrically arranged about the processing table 1. The pressure rod assembly includes a rotating frame 14 rotatably arranged on the rear axis 1 2, a supporting rod 1 15 at one end arranged on the rotating frame 14, and a supporting rod 2 16 rotatably arranged at the other end of the supporting rod 1 15. A metal rod accommodating space is formed between the rotating wheel 3, the supporting rod 1 15 and the supporting rod 2 16. The heights of the supporting rod 1 15 and the supporting rod 2 16 are higher than the height of the processing table 1 to avoid interference with the processing table 1 when bending the metal rod. In the initial state, the two groups of pressure rod assemblies are distributed flatly along a straight line. The metal rod is placed on the top of the processing table 1 and can be clamped between the two groups of pressure rod assemblies and the two rear wheels 3. The position of the metal rod is positioned during clamping. The two ends of the metal rod protrude from the outer ends of the two supporting rods 2 16 on both sides. The entire metal rod is distributed in the center. After positioning, it is prepared for subsequent bending processing.

[0024] like Figure 4 and Figure 5As shown, two groups of pushing assemblies are symmetrically arranged about the processing table 1. The pushing assemblies include a connecting frame 9 that rotates around the rear axis 2, a mounting shaft 10 arranged at the outer end of the connecting frame 9, and a push wheel 11 rotatably arranged on the mounting shaft 10. The push wheel 11 rolls on the outer surface of the leaning rod 16 to push the leaning rod 16 to rotate. The push wheel 11 rolls on the leaning rod 16 to avoid sliding wear.

[0025] The drive mechanism is used to drive the two pusher assemblies to rotate toward each other for closing or away from each other for expanding. When the two pusher assemblies are closing, the metal rods are first bent from straight into a U-shaped rod using the first and second support rods 15 and 16. The U-shaped rods are then bent into rounded rectangular rods using the second support rod 16. When the two pusher assemblies are expanding, workers can remove the bent rounded rectangular rods.

[0026] An incomplete gear 18 is provided on the rear axle 1, and a guide platform 21 is provided on the support rod 15. A slide rod 20 is slidably provided on the guide platform 21. A rack 19 is provided at one end of the slide rod 20, which meshes with the incomplete gear 18. As the rack 19 and the slide rod 20 rotate with the guide platform 21, the meshing position of the rack 19 and the incomplete gear 18 changes dynamically. An insertion platform 22 is provided on the support rod 26. The insertion platform 22 has a socket for inserting the other end of the slide rod 20. When the support rods 15 and 16 bend the metal rod from a straight rod into a U-shaped rod, the slide rod 20 is inserted into the socket. After the support rods 15 and 16 have bent the metal rod from a straight rod into a U-shaped rod, the rack 19 rotates around the incomplete gear 18 and gradually moves backward, causing the slide rod 20 to move out of the socket. When the metal rod is subsequently bent from a U-shaped rod into a rounded rectangular rod by the second supporting rod 16, the first supporting rod 15 does not rotate, and the push wheel 11 drives the second supporting rod 16 to rotate, and the metal rod is subsequently bent by the second supporting rod 16. The connecting frame 9 is lower than the height of the processing table 1, and when the connecting frame 9 rotates inward, it will not interfere with the processing table 1 and the support legs 23.

[0027] During the process of bending the metal rod from a straight rod into a U-shaped rod by the first and second supporting rods 15 and 16, the first and second supporting rods 15 and 16 rotate inward, and the first and second supporting rods 15 and 16 are in contact with the outside of the metal rod, which is conducive to the regular bending of the metal rod. The rack 19 remains engaged with the incomplete gear 18 and rotates around the incomplete gear 18. At the same time, the rack 19 moves backward, driving the slide bar 20 to move, and the slide bar 20 moves out of the insertion hole of the insertion platform 22, thereby releasing the linkage between the first and second supporting rods 15 and 16. When the metal rod is subsequently bent from a U-shaped rod into a rounded rectangular rod, the push wheel 11 can push the second supporting rod 16 alone to achieve the bending process.

[0028] After the metal rod is initially positioned and clamped, this embodiment can automatically position and bend it. First, the metal rod is bent from a straight rod into a U-shaped rod using the first supporting rod 15 and the second supporting rod 16. There is no need to remove the metal rod at this time. Instead, the metal rod can be bent in this state. Specifically, the second supporting rod 16 is used to bend the U-shaped rod into a rounded rectangular rod, which avoids repeated clamping and positioning, saves time, and improves bending efficiency.

[0029] Example 2, as Figures 1-6 As shown, this embodiment proposes an automatic positioning ton barrel metal rod bending device. Compared with the first embodiment, in this embodiment, the top of the second support rod 16 has a convex plate portion, and the top of the installation shaft 10 is connected to the connecting plate 12. The outer end of the connecting plate 12 is rotatably provided with a pulley 13, which is rolled on the convex plate portion. The pulley 13 and the push wheel 11 are respectively located on both sides of the convex plate portion. After the metal rod is bent into a rounded rectangular rod, the two sets of pushing assemblies are driven outward by the driving mechanism. The installation shaft 10 drives the pulley 13 to move through the connecting plate 12. The pulley 13 rolls on the convex plate portion, pulling the second support rod 16 outward, avoiding manual outward pulling of the second support rod 16.

[0030] like Figure 5 As shown, a baffle 17 is provided on the outer side of the first leaning rod 15 to limit the outward rotation range of the second leaning rod 16, specifically limiting the outward rotation range of the second leaning rod 16 relative to the first leaning rod 15. After the pull wheel 13 pulls the second leaning rod 16 outward until it is aligned with the first leaning rod 15, the second leaning rod 16 also contacts the baffle 17. As the pull wheel 13 continues to move outward, the second leaning rod 16 and the baffle 17 can drive the first leaning rod 15 to rotate outward until the two sets of pressure rod assemblies are rotated to the initial state of being aligned and straight, i.e., automatically reset.

[0031] When the two groups of pressure rod assemblies are rotated to the initial state of being distributed straightly along a straight line, that is, when automatically reset, the support rod 15 and the support rod 2 16 are rotated outward to allow the slide rod 20 to be reinserted into the socket to prepare for the next subsequent bending process.

[0032] This embodiment can automatically adjust the two groups of pressure rod assemblies to the initial state and automatically reset after the metal rod is bent into the rounded rectangular rod, so as to facilitate the removal of the rounded rectangular rod and prepare for the next bending process.

[0033] Example 3, as Figures 1-6As shown, this embodiment proposes an automatic positioning ton barrel metal rod bending device. Compared to the first embodiment, this embodiment has a drive mechanism comprising a telescopic mechanism 4 disposed at the bottom of a processing table 1, a double-sided rack 5 horizontally disposed at the output end of the telescopic mechanism 4, and two symmetrically arranged gear transmission assemblies meshing with the double-sided rack 5. The telescopic mechanism 4 utilizes a hydraulic cylinder. The gear transmission assembly comprises a rotating shaft 7 rotatably disposed at the bottom of the processing table 1, a gear 1 6 mounted on the rotating shaft 7, and a gear 2 8 rotatably mounted on shaft 1 2. Gear 1 6 meshes with both the double-sided rack 5 and gear 2 8. A connecting frame 9 is disposed on the gear transmission assembly, specifically on the bottom surface of gear 2 8. When the telescopic mechanism 4 contracts to drive the double-sided rack 5 inward, gear 1 6 drives gear 2 8 to rotate, which in turn drives the connecting frame 9. The transmission ratio between gear 1 6 and gear 2 8 is greater than 1, providing greater torque for the bending process.

[0034] In this embodiment, the telescopic mechanism 4 is extended and retracted to realize the outward and inward rotation of the two pushing assemblies in a linked manner. The action form is simplified and the bending effect of the bending device is reliable.

[0035] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
