Description

Technical Field

[0001] This utility model relates to the field of curved frame production equipment, specifically a frame tail hook forming device. Background Technology

[0002] With the development of industry, people's perception of wire shapes is no longer limited to simple straight lines. As a result, many frame products made by bending wire have appeared on the market. The production of frame products often involves processes such as wire coil feeding, straightening, 2D bending, welding, 3D bending, punching, and final stacking. Currently, production is generally carried out manually. In mass production, manually processed metal wire suffers from uneven deformation, large internal stress, and inadequate requirements for spacing, bending accuracy, and welding points. This increases labor intensity and reduces safety. Moreover, manual bending of frames requires high labor costs, the processing steps are cumbersome, and quality is difficult to control, resulting in low production efficiency and failure to meet production needs. Therefore, this paper proposes a device that can be adapted to fully automated production for the aforementioned 3D bending process. Utility Model Content

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] refer to Figure 1 As shown, the frame tail hook forming device includes a machine base 1. On one side of the machine base 1 along the frame conveying direction, there are sequentially arranged a punching mechanism 51 for bending one tail end of the frame upward, an outward bending mechanism 52 for bending the upward folded part of the frame outward, and a punching mechanism 53 for flattening the outward folded part of the frame. On the other side of the machine base 1 along the frame conveying direction, there are sequentially arranged a bending mechanism 54 for rolling the other tail end of the frame and an upward bending mechanism 55 for bending the rolled part of the frame upward.

[0032] This frame tail hook forming device can automatically form the tail hooks at both ends of the frame. The operation is precise and error-free, requiring no frequent manual intervention.

[0033] A punching guide mechanism 56 for clamping the frame is also provided between the punching bending mechanism 51 and the outward folding mechanism 52, between the outward folding mechanism 52 and the punching flattening mechanism 53, and between the bending mechanism 54 and the upward folding mechanism 55. The punching guide mechanism 56 can clamp the frame for fixation and re-energization when the above mechanisms process the frame, thereby improving processing accuracy and stability.

[0034] In this embodiment, reference Figure 2As shown, the bending mechanism 51 includes a bending moving platform 511, on which an upper bending cylinder 512 and a lower bending cylinder 513 are provided. A punching seat is connected to the telescopic shaft of both the upper bending cylinder 512 and the lower bending cylinder 513. A guide post 519 is provided on the bending moving platform 511, which is linearly slidingly engaged with the punching seat 514. The upper punching seat 515 is connected to an upper folding die 516. A right punch 5161 is provided on the bottom surface of the upper folding die 516. The lower punching seat 514 is connected to an upper folding die 517. A left punch 5171 is provided on the top surface of the upper folding die 5171. A bending pressure roller 518 is also rotatably connected to the left punch 5171.

[0035] The working principle of the bending mechanism 51 mentioned above:

[0036] The frame is moved from one end to the upper folding mold 516 and the lower folding mold 517. Then, the upper bending cylinder 512 and the lower bending cylinder 513 are activated to push the upper folding mold 516 and the lower folding mold 517 to move relative to each other. At this time, the left punch 5171 and the right punch 5161 overlap left and right, thereby bending the end of the frame upward. During the bending process, the bending roller 518 is used to reduce the wear of the upper folding mold 517 on the frame, so that the surface of the upper folding part remains smooth.

[0037] In this embodiment, reference Figure 3 and Figure 4 As shown, the outward folding mechanism 52 includes an outward folding moving platform 521. The outward folding moving platform 521 is provided with an upper outward folding cylinder 522 and a lower outward folding cylinder 523. The telescopic shaft of the upper outward folding cylinder 522 is connected to an outward folding bottom mold assembly 524. The outward folding bottom mold assembly 524 is provided with a frame clamping structure 525. The telescopic shaft of the lower outward folding cylinder 523 is connected to an outward folding upper mold assembly 526. The outward folding moving platform 521 is provided with a guide post 527 that linearly slides with the outward folding upper mold assembly 526 and the outward folding bottom mold assembly 524. The outward folding upper mold assembly 526 is provided with a pressure plate assembly 528 that abuts against the outward folding bottom mold assembly 524.

[0038] Specifically: the outer folding bottom mold assembly 524 includes an outer folding lower seat 5241 and an outer folding bottom mold 5242 connected to the bottom surface of the outer folding lower seat 5241. An outer folding push head 5243 is laterally slidably connected inside the outer folding bottom mold 5242. A first spring 5244 is provided between the outer folding push head 5243 and the outer folding bottom mold 5242. An outer folding fixing platform 5245 is provided on the outer side of the outer folding bottom mold 5242. A bending shaft 5246 that moves back and forth relative to the outer folding fixing platform 5245 is connected to the outer folding push head 5243.

[0039] The frame clamping structure 525 includes a clamping guide plate 5251 connected to the outside of the outward folding bottom mold 5242. A clamping block 5252 that moves back and forth relative to the outward folding fixing table 5245 is slidably connected on the clamping guide plate 5251. A second spring 5253 is provided between the clamping block 5252 and the clamping guide plate 5251. The front end of the clamping block 5252 is provided with a cavity that matches the shape of the frame. A clamping cavity 5254 is formed between the cavity and the outward folding fixing table 5245.

[0040] The outer folding upper mold assembly 526 includes an outer folding upper seat 5261 and an outer folding upper mold 5262. The outer folding upper mold 5262 extends upward with an outer folding punch 5263 that pushes the outer folding push head 5243 and a clamping punch 5264 that pushes the clamping block 5252.

[0041] The pressure plate assembly 528 includes a pressure plate 5281 and a third spring 5282. The two ends of the pressure plate 5281 are provided with two guide posts 5283, which are linearly slidably connected in the outer folding upper seat 5261. The third spring 5282 abuts against the pressure plate 5281 and the outer folding upper seat 5261.

[0042] The working principle of the above-mentioned outward folding mechanism 52:

[0043] After bending upwards at one end of the frame, the subsequent upward bending section (such as...) Figure 10 The P1 mark is transferred between the outer folding bottom mold 5242 and the outer folding upper mold 5262. Then, the upper outer folding cylinder 522 and the lower outer folding cylinder 523 are activated to push the outer folding bottom mold assembly 524 and the outer folding upper mold assembly 526 to move relative to each other. At this time, the clamping punch column 5264 pushes the inclined surface on the outside of the clamping block 5252 from top to bottom, so that the clamping block 5252 slides laterally toward the outer folding fixing table 5245. After the two come into contact, the upward bending part of the frame is clamped in the clamping cavity 5254.

[0044] Subsequently, the outer bending punch 5263 pushes the outer inclined surface of the outer bending push head 5243 from top to bottom, causing the outer bending push head 524 to slide laterally, while driving the bending shaft 5246 to move towards the outer bending fixed table 5245, thereby bending the upward bending part outward to form a shape. Finally, the bottom bending die assembly 524 and the upper outer bending die assembly 526 are released from the frame.

[0045] In addition, after the bottom folding mold assembly 524 and the top folding mold assembly 526 are engaged, the pressure plate 5281 presses against the bottom surface of the bottom folding mold 5242. When the frame is released, the third spring 5282 assists in separating the bottom folding mold assembly 524 and the top folding mold assembly 526. The first spring 5244 and the second spring 5253 also help to reset the top folding push head 5243 and the clamping block 5252.

[0046] In this embodiment, reference Figure 5 and Figure 6 As shown, the flattening mechanism 53 includes a flattening moving platform 531, on which an upper flattening cylinder 532 and a lower flattening cylinder 533 are provided. The telescopic shafts of the upper flattening cylinder 532 and the lower flattening cylinder 533 are respectively connected to two relatively moving punches 534. The flattening moving platform 531 is provided with a flattening bottom mold 535. An outward folding positioning cavity 5351 is opened in the flattening bottom mold 535, and a punch through hole 5352 is opened on the flattening bottom mold 535 through the frame positioning cavity.

[0047] The aforementioned outwardly folded positioning cavity 5351 has a laterally open triangular structure. The outwardly bent portion of the frame is positioned at the bottom end of the outwardly folded positioning cavity 5351. The punch through hole 5352 is opened on the upper and lower sides of this bottom end. Based on this structure, the working principle of the aforementioned flattening mechanism 53 is as follows:

[0048] After bending outwards at one end of the frame, the subsequent outward bending section (such as...) Figure 10 The P2 mark is positioned at the bottom of the outward folding positioning cavity 5351. Then, the upper flattening cylinder 532 and the lower flattening cylinder 533 are activated to push the upper and lower punches 534 through the punch through-hole 5352, flattening the outwardly bent portion, thereby flattening the outwardly bent portion into a semi-circular flat section (such as...). Figure 10 (P3 mark).

[0049] In this embodiment, reference Figure 7 As shown, the bending mechanism 54 includes a bending moving platform 541, a bending servo motor 542 fixed on the bending moving platform 541, a bending turntable 543 fixed on the rotating shaft of the bending servo motor 542, a bending bottom pin 544 provided at the center position on the outer side of the bending turntable 543, and a bending block 545 provided on the outer side of the bending turntable 543 next to the bending bottom pin 544. The bending turntable 543 drives the bending block 545 to rotate around the bending bottom pin 544, and the end of the bending block 545 near the bending bottom pin 544 is provided with a bending end face 5451.

[0050] While one end of the frame is being processed by the punching and bending mechanism 51, the other end of the frame is being processed by the bending mechanism 54. The working principle of the bending mechanism 54 is as follows:

[0051] The other end of the frame is moved to the underside of the bending bottom pin 544. At this time, the bending block 545 is located under the end of the frame. The bending servo motor 542 starts and drives the bending turntable 543 to rotate. When the bending turntable 543 rotates, it drives the bending block 545 to rotate in the opposite direction around the bending bottom pin 544 as the center point. During the rotation, the bending block 545 uses the bending end face 5451 to press and push the end of the frame to bend, thereby enabling the other end of the frame to be wound.

[0052] In this embodiment, reference Figure 8 As shown, the upper folding mechanism 55 includes an upper folding moving platform 551, on which an upper punching cylinder 552 and a lower punching cylinder 553 are provided. A punching seat 2 is connected to the telescopic shaft of the upper punching cylinder 552 and the lower punching cylinder 553. A guide post 3 554 is provided on the upper folding moving platform 551 that slides linearly with the punching seat 2. The upper punching seat 2 555 is connected to the upper punching die 556, and the lower punching seat 2 557 is connected to the lower punching die 558. The upper punching die 556 and the lower punching die 558 move relative to each other and form a mold cavity 559 that matches the shape of the bent portion of the frame.

[0053] While one end of the frame is being processed by the outward folding mechanism 52, the other end of the frame is being processed by the upward folding mechanism 55. The working principle of the upward folding mechanism 55 is as follows:

[0054] After the other end of the frame is bent, it is then transferred between the upper punch die 556 and the lower punch die 558. Then, the upper punch cylinder 552 and the lower punch cylinder 553 are activated to push the upper punch die 556 and the lower punch die 558 to move relative to each other. At this time, the upper punch die 556 and the lower punch die 558 are aligned vertically, thereby bending the bent portion of the frame (such as...). Figure 10 The P4 mark) is clamped inside the mold cavity 559, and the inclined surface at the bottom of the mold cavity 559 is used to make the bending part bend upward (as shown in the image). Figure 10 (P5 mark).

[0055] In this embodiment, reference Figure 9 As shown, the punched wire-blocking mechanism 56 includes a wire-blocking support 561, a bottom baffle 562 fixed on the wire-blocking support 561, and a wire-pressing cylinder 563. The wire-pressing cylinder 563 has a wire-pressing cylinder head 564 on its telescopic shaft. The bottom baffle 562 is located below the wire-pressing cylinder head 564, and its top surface is provided with a side stop block 565. The side stop block 565 is recessed with an avoidance recess 5651 corresponding to the wire-pressing cylinder head 564. The side stop block 565 can achieve lateral positioning of the frame, so that the tail end of the frame can be aligned with the above-mentioned mechanisms.

[0056] Any mobile platform includes the bending mobile platform 511 (e.g.) Figure 2 As shown), the outward-folding mobile platform 521 (as shown) Figure 3 As shown), the flattened mobile platform 531 (as shown) Figure 5 As shown), bending moving platform 541 (as shown) Figure 7 (as shown) and the folding mobile platform 551 (as shown) Figure 8 (as shown)

[0058] The base plate 571 and the mounting base 572, through the cooperation of the fixed slide rail assembly 581 and the moving slide block assembly 582, can adjust the depth of the punching and bending mechanism 51, the outward folding mechanism 52, the punching and flattening mechanism 53, the bending mechanism 54 and the upward folding mechanism 55, so that the frame tail hook forming device can adapt to the processing requirements of frames of different specifications.

[0059] The bending moving platform 511, the outward folding moving platform 521, and the upward folding moving platform 551 have basically the same structure.

The horizontal adjustment plate 575 and the base plate 571 are also provided with a longitudinal fixed slide rail assembly 581 and a movable slide block assembly 582 (consistent with other moving platforms). The difference is that the horizontal adjustment plate 575 and the mounting base 572 are provided with a transverse fixed slide rail assembly 581 and a movable slide block assembly 582, so that the bending mechanism 54 can perform transverse translational movement and longitudinal translational movement at the same time. Moreover, the horizontal adjustment plate 575 is provided with a bending adjustable cylinder 576, and the telescopic shaft of the bending adjustable cylinder 576 is connected to the horizontal adjustment plate 575.
