Description

Technical Field

[0001] The present invention relates to the technical field of integrated aluminum row processing equipment, especially the technical field of integrated aluminum row processing equipment.

Background Art

[0002] As a component that must be used in electrical equipment, aluminum rows are now also used in new energy vehicles as electrical components. Many electrical equipment are required in new energy vehicles, and electrical cable laying is needed for these electrical equipment. Aluminum rows are used during the laying process. The aluminum rows in the prior art have the technical problem that the fixed electrical cables are not stable enough.

[0003] To solve the above problems, the hard aluminum row for new energy vehicles with the application number 202021344724.5 is disclosed. When this utility model is in use, it relies on the connection cavity on the aluminum row to route wires inside the connection cavity. When routing wires, it can rely on the position change of the adjusting rod. When the position of the adjusting rod changes, it can drive the clamp to move, and the clamp can be used to fix the electrical cables during wire routing, making the electrical cables more stable during wire routing.

[0004] Although the hard aluminum row for new energy vehicles disclosed in the application number 202021344724.5 can fix the cables in its inner hole in an orderly manner, its structure is complex and the forming process is cumbersome. While traditional aluminum rows will pass multiple cables through the same inner hole during wire routing, which is not conducive to the orderly arrangement of the cables.

[0005] Therefore, the company has developed and designed an integrated aluminum row that can arrange cables in an orderly manner. Further, in order to mass-produce the integrated aluminum row, the corresponding integrated aluminum row processing equipment has been developed to achieve the high-efficiency production of the integrated aluminum row.

[0022] Among them, a waste discharge channel 14 is formed between the outer side wall of the lower U-shaped plate 31 and the inner wall of the lower U-shaped groove 13.

[0023] Working process of the present invention:

[0024] During the working process of the integrated aluminum row processing equipment of the present invention, all components of the equipment are controlled by a PLC controller to operate;

[0025] The first step: Take a straight round tube and place the straight round tube in the limiting U-shaped groove 122 in the right forming U-shaped groove 12. The length of the straight round tube should be shorter than the sum of the lengths of the right forming U-shaped groove 12 and the middle forming U-shaped groove 121;

[0026] Step 2: The electric push rod 24 is activated, and the first forming straight rod 21, the second forming straight rod 22, and the guiding conical rod 23 move rightward synchronously. Since the axis of the limiting U-shaped groove 122 is coplanar with the axes of the first forming straight rod 21, the second forming straight rod 22, and the guiding conical rod 23 in the vertical direction, the left port of the straight circular tube has been aligned with the guiding conical rod 23. The small-diameter end size of the guiding conical rod 23 here is smaller than the inner hole size of the straight circular tube, so that the guiding conical rod 23 can enter the inner hole of the straight circular tube after moving rightward. When the guiding conical rod 23 moves rightward into the inner hole of the straight circular tube, and the conical surface of the conical rod 23 presses the straight circular tube against the rightmost inner wall of the right forming U-shaped groove 12, the electric push rod 24 is closed;

[0027] Step 3: The second lifting device 41 descends, and the upper forming pressing plate 44 moves downward to press the top end of the straight circular tube, and then the second lifting device 41 stops descending;

[0028] Step 4: The second lifting device 41 and the electric push rod 24 are activated synchronously. The second lifting device 41 descends and the electric push rod 24 extends. The straight circular tube is gradually flattened by the upper forming pressing plate 44. At the same time, under the guiding action of the guiding conical rod 23, the second forming straight rod 22 will enter the inner hole of the straight circular tube and support the inner hole of the straight circular tube. Under the mutual extrusion of the second forming straight rod 22, the upper forming pressing plate 44, and the right forming U-shaped groove 12, the straight circular tube will be pressed into a straight flat tube sleeved on the second forming straight rod 22. Then, both the second lifting device 41 and the electric push rod 24 are closed. At this time, the first forming straight rod 21 is still located on the left side of the straight flat tube. There are gaps between the lower end face, the front and rear end faces of the second forming straight rod 22 and the inner bottom, the front and rear inner walls of the right forming U-shaped groove 12, and the width of the gaps is equal to the wall thickness of the straight circular tube;

[0029] Step 5: Keeping the position of the upper forming pressing plate 44 unchanged, the electric push rod 24 is activated, and the first forming straight rod 21, the second forming straight rod 22, and the guiding conical rod 23 continue to move rightward. The guiding conical rod 23 enters the guiding hole 1203 of the intermediate die. The first forming straight rod 21 enters the inner hole of the straight flat tube under the transition of the fillet and enlarges the left end of the inner hole of the straight flat tube, completing the diameter expansion of the left end of the inner hole of the straight flat tube. The inner hole diameter after the diameter expansion of the left end of the straight flat tube is equal to the outer diameter of the right end of the straight flat tube;

[0030] Step 6: Maintain the positions of the upper forming plate 44, the first forming straight rod 21, the second forming straight rod 22, and the guide tapered rod 23, and then synchronously start the first lifting device 32 and the third lifting device 421 to punch and groove the straight flat tube. After the first lifting device 32 rises, the lower limit plate 33 will support the plurality of lower groove forming vertical plates 34 to move upward. Since the plurality of lower groove forming vertical plates 34 correspond one-to-one to the plurality of lower mold guide holes 1202, and the plurality of lower forming grooves 2203 correspond one-to-one to the plurality of lower mold guide holes 1202, the lower groove forming vertical plates 34 will pass through the lower mold guide holes 1202 and enter the lower forming grooves 2203, and the lower groove forming vertical plates 34 will push the lower mold guide holes 1202 into the lower forming grooves 2203 in the process of entering the lower forming grooves 2203. The straight flat tube body at the notch of the forming groove 2203 is squeezed and deformed into a groove; after the third lifting device 421 descends, the upper punching vertical rod 431 and the upper groove forming vertical plate 432 will both descend, and the upper punching vertical rod 431 descends and passes through the upper guide through hole 4401, the upper end tube body of the straight flat tube, the middle guide through hole 2201, the lower end tube body of the straight flat tube, and the lower waste discharge hole 1201 in sequence. When the upper punching vertical rod 431 passes through the upper end tube body and the lower end tube body of the straight flat tube, the punching is completed, and the upper groove forming vertical plate 432 descends and passes through the upper mold guide hole 4402 and then enters the upper forming groove 2202. In the process of the upper groove forming vertical plate 432 entering the upper forming groove 2202, the straight flat tube body at the notch of the upper forming groove 2202 will be squeezed and deformed into a groove;

[0031] Step 7: After completing the punching and grooving of the straight flat tube, the electric push rod 24, the first lifting device 32, the second lifting device 41, and the third lifting device 421 are started again and reset away from the finished product. Since the radial cross-sectional dimension of the middle forming U-shaped groove 121 is larger than the radial cross-sectional dimension of the right forming U-shaped groove 12 and the left U-shaped groove 11, the right ends of the several upper forming grooves 2202 and the several lower forming grooves 2203 all penetrate the right end face of the guide tapered rod 23. Therefore, the part of the tube body after the diameter expansion at the left end of the inner hole of the straight flat tube will be stuck by the middle forming U-shaped groove 121 and axially restricted in the middle forming U-shaped groove 121. Then, after the electric push rod 24 is shortened, the first forming straight rod 21, the second forming straight rod 22, and the guide tapered rod 23 will move left away from the inner hole of the finished product.

[0032] Step 8: Start the first lifting device 32 again. At this time, the lifting height of the first lifting device 32 is higher than the height when processing the groove of the straight flat tube. Several lower groove forming vertical plates 34 move up to push the finished product out of the right forming U-shaped groove 12, completing the discharge of the finished product.

[0033] The structure of the present invention is simple and reasonably designed, which can integrally form the aluminum row and achieve high-efficiency production of the aluminum row. By setting the left U-shaped groove 11, it not only provides a moving space for the first forming straight rod 21, the second forming straight rod 22, and the guiding conical rod 23, but also guides the movement of the first forming straight rod 21, the second forming straight rod 22, and the guiding conical rod 23. By setting a combination structure of the first forming straight rod 21, the second forming straight rod 22, and the guiding conical rod 23 with a gradually decreasing diameter from left to right in sequence, with several upper forming grooves 2202 and several lower forming grooves 2203 penetrating the right end face of the guiding conical rod 23, it can ensure that after the intermediate die 2 shapes the inner hole of the straight round tube, the groove structure on the finished product will not interfere with the leftward movement of the combination structure of the first forming straight rod 21, the second forming straight rod 22, and the guiding conical rod 23 driven by the intermediate die 2, facilitating the separation of the intermediate die 2 from the finished product. By setting the right forming U-shaped groove 12, the middle forming U-shaped groove 121, and the lower forming die 3, the lower end structure of the aluminum row can be processed and formed.
