Technical Field

[0001] The present invention relates to the field of bending equipment, and particularly to a bending equipment for ton barrel metal rods with automatic positioning. Background Art

[0002] For the outer frame of a ton barrel, multiple rounded rectangular metal rods are required, and multiple rounded rectangular metal rods and straight rods are welded into the outer frame. The rounded rectangular metal rods are processed by bending equipment.

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

[0005] The object of the present invention is to address the problems in the background art and propose a bending equipment for ton barrel metal rods with automatic positioning. After the initial positioning and clamping, subsequent automatic positioning and bending can be achieved, avoiding repeated clamping and positioning, saving time, and improving the bending efficiency.

The pressing rod assembly includes a rotating frame rotatably arranged on the rear row of fixed shafts, a first leaning rod with one end arranged on the rotating frame, and a second leaning rod rotatably arranged at the other end of the first leaning rod. A metal rod accommodating space is formed among the rotating wheel, the first leaning rod, and the second leaning rod; two groups of pushing and pressing assemblies are symmetrically arranged with respect to the processing table; the driving mechanism is used to drive the two groups of pushing and pressing assemblies to rotate towards each other to close or rotate away from each other to expand. When the two groups of pushing and pressing assemblies close, first, the first leaning rod and the second leaning rod are used to bend the metal rod from a straight rod into a U-shaped rod, and then the second leaning rod is used to bend the U-shaped rod into a rounded rectangular rod; an incomplete gear is arranged on the rear row of fixed shafts, a guiding platform is arranged on the first leaning rod, a sliding rod is slidably arranged on the guiding platform, a rack meshingly connected with the incomplete gear is arranged at one end of the sliding rod, an inserting platform is arranged on the second leaning rod, and the inserting platform has an inserting hole for the other end of the sliding rod to insert. During the process of bending the metal rod from a straight rod into a U-shaped rod by the first leaning rod and the second leaning rod, the sliding rod is inserted into the inserting hole. After the metal rod is bent from a straight rod into a U-shaped rod by the first leaning rod and the second leaning rod, the sliding rod is removed from the inserting hole.

[0007] Preferably, the pushing component includes a connecting frame that rotates around the rear row fixed shaft, a mounting shaft arranged at the outer end of the connecting frame, and a pushing wheel rotatably arranged on the mounting shaft.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects: After the metal rod is initially positioned and clamped in the present invention, subsequent automatic positioning and bending can be carried out. First, the first supporting rod and the second supporting rod are used to bend the metal rod from a straight rod into a U-shaped rod. It is not necessary to remove the metal rod at this time.

Detailed implementation manners

[0016] Example 1, as Figures 1-6 shown, an automatic positioning bending device for metal rods of ton barrels proposed in this embodiment includes a processing table 1, a pressing rod assembly, a pushing and pressing assembly, and a driving mechanism.

[0017] Four fixed shafts are arranged in a rectangular array on the processing table 1. The four fixed shafts are fixedly arranged. The four fixed shafts are respectively the two first shafts 2 in the back row and the two second shafts 201 in the front row. Rotating runners 3 are arranged on the four fixed shafts respectively, and the four runners 3 are respectively used for bending and positioning the four corners of a rounded rectangular metal rod. A plurality of legs 23 are arranged at the bottom of the processing table 1. The four corners of the processing table 1 are rounded to prevent interference with the pressing rod assembly and are safer. The rear end of the processing table 1 has an extended plate part. When initially placing the metal rod, the extended plate part expands the supporting range. If the worker does not place the metal rod in place, the metal rod may slide onto the extended plate part, thus preventing it from falling to the ground.

[0018] As Figures 1-4 shown, two groups of pressing rod assemblies are arranged symmetrically about the processing table 1. The pressing rod assembly includes a rotating frame 14 rotatably arranged on the first shaft 2 in the back row, a first supporting rod 15 with one end arranged on the rotating frame 14, and a second supporting rod 16 rotatably arranged at the other end of the first supporting rod 15. A metal rod accommodating space is formed among the runner 3, the first supporting rod 15, and the second supporting rod 16. The heights of the first supporting rod 15 and the second supporting rod 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 pressing rod assemblies are distributed straight along a straight line. When the metal rod is placed on the top of the processing table 1, it can be clamped between the two groups of pressing rod assemblies and the two runners 3 in the back row. When clamping, the position of the metal rod is positioned. The two ends of the metal rod protrude from the outer ends of the two second supporting rods 16 on both sides, and the whole metal rod is centered. After positioning, subsequent bending treatment is prepared.

[0019] As Figure 4 and Figure 5 shown, two groups of pushing and pressing assemblies are arranged symmetrically about the processing table 1. The pushing and pressing assembly includes a connecting frame 9 rotating around the first shaft 2 in the back row, a mounting shaft 10 arranged at the outer end of the connecting frame 9, and a pushing wheel 11 rotatably arranged on the mounting shaft 10. The pushing wheel 11 is in rolling connection with the outer side surface of the second supporting rod 16 and is used to push the second supporting rod 16 to rotate. The pushing wheel 11 rolls on the second supporting rod 16 to avoid sliding wear.

[0020] The driving mechanism is used to drive two sets of pressing components to rotate towards each other to close or rotate away from each other to expand. When the two sets of pressing components close, first use the first support rod 15 and the second support rod 16 to bend the metal rod from a straight rod into a U-shaped rod, and then use the second support rod 16 to bend the U-shaped rod into a rounded rectangular rod. When the two sets of pressing components expand, the worker can remove the bent rounded rectangular rod.

[0021] An incomplete gear 18 is arranged on the rear row shaft one 2, a guiding platform 21 is arranged on the first support rod 15, a sliding rod 20 is slidably arranged on the guiding platform 21, a rack 19 meshed with the incomplete gear 18 is arranged at one end of the sliding rod 20, and when the rack 19 and the sliding rod 20 rotate with the guiding platform 21, the meshing position of the rack 19 and the incomplete gear 18 changes dynamically. A plugging platform 22 is arranged on the second support rod 16, and the plugging platform 22 has a jack for the other end of the sliding rod 20 to be inserted. During the process of bending the metal rod from a straight rod into a U-shaped rod by the first support rod 15 and the second support rod 16, the sliding rod 20 is in a state of being inserted into the jack. After the first support rod 15 and the second support rod 16 bend 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, and the sliding rod 20 moves out of the jack. When subsequently bending the metal rod from a U-shaped rod into a rounded rectangular rod by the second support rod 16, the first support rod 15 does not rotate, and the pushing wheel 11 pushes the second support rod 16 to rotate, and the subsequent bending of the metal rod is carried out by using the second support rod 16. The connecting frame 9 is lower than the height of the processing table 1, and when the connecting frame 9 rotates inwards, it will not interfere with the processing table 1 and the supporting legs 23.

[0022] During the process of bending the metal rod from a straight rod into a U-shaped rod by the first support rod 15 and the second support rod 16, both the first support rod 15 and the second support rod 16 rotate inwards, and the first support rod 15 and the second support rod 16 are attached to the outer side of the metal rod, which is beneficial to regular bending of the metal rod. The rack 19 remains meshed with the incomplete gear 18, the rack 19 rotates around the incomplete gear 18, and at the same time, the rack 19 moves backward, driving the sliding rod 20 to move, and the sliding rod 20 moves out of the jack of the plugging platform 22, thereby releasing the linkage between the first support rod 15 and the second support rod 16. When subsequently bending the metal rod from a U-shaped rod into a rounded rectangular rod, the second support rod 16 can be pushed alone by the pushing wheel 11 to realize the bending process.

[0023] In this embodiment, after the metal rod is initially positioned and clamped, subsequent automatic positioning and bending can be carried out. First, use the first support rod 15 and the second support rod 16 to bend the metal rod from a straight rod into a U-shaped rod. Instead of removing the metal rod at this time, the bending of the metal rod continues in this state. Specifically, then use the second support rod 16 to bend the U-shaped rod into a rounded rectangular rod, which avoids repeated clamping and positioning, saves time, and improves the bending efficiency.

[0024] Embodiment 2, as Figures 1-6As shown in the figure, an automatic positioning bending device for the metal rod of a ton barrel proposed in this embodiment, compared with the first embodiment, in this embodiment, the top of the second supporting rod 16 has a convex plate portion, the top end of the mounting shaft 10 is connected with a connecting plate 12, a pulling wheel 13 is rotatably arranged at the outer end of the connecting plate 12, the pulling wheel 13 is in rolling connection with the convex plate portion, and the pulling wheel 13 and the pushing 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 driving mechanism drives the two pushing and pressing components to rotate outwards, the mounting shaft 10 drives the pulling wheel 13 to move through the connecting plate 12, and the pulling wheel 13 rolls at the convex plate portion to pull the second supporting rod 16 outwards, avoiding manually pulling the second supporting rod 16 outwards.

[0025] As Figure 5 shown, a baffle 17 for limiting the outer rotation range of the second supporting rod 16 is arranged on the outer side surface of the first supporting rod 15, specifically for limiting the outer rotation range of the second supporting rod 16 relative to the first supporting rod 15. After the pulling wheel 13 pulls the second supporting rod 16 outwards until it is aligned with the first supporting rod 15, the second supporting rod 16 also contacts the baffle 17. As the pulling wheel 13 continues to move outwards, the first supporting rod 15 can be driven to rotate outwards through the second supporting rod 16 and the baffle 17 until the two pressing rod components are rotated to the initial state of being linearly and straightly distributed along a straight line, that is, automatic reset.

[0026] When the two pressing rod components are rotated to the initial state of being linearly and straightly distributed along a straight line, that is, automatic reset, the first supporting rod 15 and the second supporting rod 16 will rotate outwards, causing the sliding rod 20 to be inserted into the jack again to prepare for the subsequent next bending process.

[0027] This embodiment can automatically adjust the two pressing rod components to the initial state and automatically reset after bending the metal rod into a rounded rectangular rod, so as to facilitate taking out the rounded rectangular rod and prepare for the next bending process.

[0028] Embodiment Three, as Figures 1-6 shown, an automatic positioning bending device for the metal rod of a ton barrel proposed in this embodiment, compared with the first embodiment, in this embodiment, the driving mechanism includes a telescopic mechanism 4 arranged at the bottom of the processing table 1, a double-sided rack 5 horizontally arranged at the output end of the telescopic mechanism 4, and two sets of gear transmission components symmetrically distributed and meshing with the double-sided rack 5. The telescopic mechanism 4 adopts a hydraulic cylinder. The gear transmission component includes a rotating shaft 7 rotatably arranged at the bottom of the processing table 1, a gear one 6 arranged on the rotating shaft 7, and a gear two 8 rotatably arranged on the first shaft 2. The gear one 6 is simultaneously meshed and connected with the double-sided rack 5 and the gear two 8. A connecting frame 9 is arranged on the gear transmission component, specifically on the bottom surface of the gear two 8. When the telescopic mechanism 4 contracts to drive the double-sided rack 5 to move inwards, the gear two 8 is driven to rotate through the gear one 6, and the gear two 8 drives the connecting frame 9 to rotate. The transmission ratio of the gear one 6 and the gear two 8 is greater than 1, which can provide a greater torque for the bending process.

[0029] In this embodiment, the telescopic mechanism 4 is used to drive the outer rotation and inner rotation of the two sets of pressing components through telescoping, simplifying the action form and ensuring reliable bending effect of the bending equipment.

[0030] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art.
