Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of folding and punching, more particularly, it relates to a U-shaped part folding and punching integrated equipment. BACKGROUND

[0002] The folding and punching of U-shaped parts is the core process in the processing of such parts. The folding process is to form a U-shaped profile that meets the size requirements by continuously rolling and extruding the flat blank. The punching process requires machining mounting holes or positioning holes at specific locations of the U-shaped part according to assembly requirements. In order to improve processing efficiency, U-shaped part folding and punching integrated equipment gradually replaces the traditional step-by-step processing mode. This integrated processing method not only reduces the transfer time of workpieces between different equipment, but also realizes the continuity and automation of the processing flow.

[0003] The existing U-shaped part folding and punching integrated equipment integrates the folding station and the punching station to realize the continuous processing from the blank to the formed U-shaped part with holes. The equipment first feeds the flat blank to the folding station through the feeding mechanism, and then gradually extrudes and forms the folding according to the cross-sectional size of the U-shaped part. The U-shaped part after folding is cut to the required length, and then the cut U-shaped part is transferred to the punching station. The support structure inside the punching station is adapted to the inner cavity of the U-shaped part and has a U-shaped profile shape, which can provide support for the U-shaped part during punching. Then the punch is controlled to move to complete the punching of the U-shaped part.

[0004] However, in the actual processing flow of the U-shaped part, the workpiece is cut according to production requirements after the folding process is completed to obtain a single U-shaped part that meets the length requirements. In this linking link, processing obstacles often occur. Due to the influence of factors such as material stress release, processing equipment precision deviation, or uneven clamping force, the end of the U-shaped part is prone to micro-deformation, such as side edge expansion and end port inclination, during the folding and cutting process. The support structure in the punching station is a solid fixed profile design, which has high requirements for the insertion posture and size accuracy of the U-shaped part. When the deformed U-shaped part is sent in, the deformed part will interfere with the support structure, causing the workpiece to fail to smoothly extend into place. Not only does this require operators to stop and manually adjust, but it can also cause equipment jamming, reducing overall processing efficiency. SUMMARY

[0053] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0054] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0055] Please see Figures 1-17 The present invention provides the following technical solutions:

[0056] Example 1, see Figure 1 and Figure 2 A U-shaped part folding and punching integrated device includes a base 1, and a folding component 2 is installed on the top of the base 1. The folding component 2 is used to continuously fold the U-shaped part material.

[0057] See Figure 2 The folding assembly 2 includes a workbench 21 mounted on the top of the base 1. Multiple sets of rolling and folding mechanisms 22 are mounted on the top of the workbench 21. The multiple sets of rolling and folding mechanisms 22 are arranged at equal intervals on the top of the workbench 21. When the U-shaped raw material plate passes through the multiple sets of rolling and folding mechanisms 22, the plate is gradually rolled and folded by the multiple sets of rolling and folding mechanisms 22 to form a U-shaped part.

[0058] See Figure 2 and Figure 3Each set of roll-folding mechanism 22 comprises two bearing seats 221 symmetrically mounted on the top of the workbench 21, the top of each bearing seat 221 is slidingly connected with a sliding seat 222, the two sliding seats 222 and the two bearing seats 221 are rotationally connected with a rotating shaft 223, the outer side wall of each rotating shaft 223 is sleeved with a roller set 224 for edge folding, the roller set 224 is adaptively arranged according to the U-shaped piece forming process, and the end of the rotating shaft 223 is externally connected with a driving device, which can be a servo motor, not limited here, the driving device applies a driving force to the rotating shaft 223, so that the roller set 224 can rotate, the rotating directions of the two opposite roller sets 224 are opposite, when the U-shaped piece raw material plate reaches the position of the roller set 224, the roller set 224 rotates on the outer wall of the rotating shaft 223, thereby rolling the U-shaped piece raw material plate, thereby forming a U-shaped piece, the sliding seat 222 can slide on the top of the bearing seat 221, thereby adjusting the distance between the two sets of roller sets 224, thereby adapting to U-shaped piece raw materials of different thicknesses.

[0059] Referring to Figure 1 , the top of the base 1 is provided with a punching and cutting assembly 3, which is located on one side of the edge folding assembly 2, and the punching and cutting assembly 3 is used for cutting the U-shaped piece of a certain length after being folded by the edge folding assembly 2, and the specific structure of the punching and cutting assembly 3 is as follows:

[0060] Referring to Figure 1 , Figures 4-5 , the punching and cutting assembly 3 comprises a supporting seat 31 mounted on the top of the base 1, an inclined driving oil cylinder 33 mounted on the top of the supporting seat 31, an inclined slot formed in the side wall of the supporting seat 31, a cutter 32 slidingly connected in the inclined slot, the piston rod of the driving oil cylinder 33 connected with the cutter 32, the cutter 32 arranged on the side of the supporting seat 31 away from the edge folding assembly 2, and a profiling through slot 34 formed in the side wall of the supporting seat 31 and the side wall of the cutter 32, the U-shaped piece after being folded is arranged in the profiling through slot 34 and passes through the inside of the profiling through slot 34 to a predetermined length, and then the cutter 32 is pushed to slide in the inclined slot by the driving oil cylinder 33, so that the U-shaped piece of a certain length moves a distance with the cutter 32, thereby cutting the U-shaped piece of a certain length.

[0061] Referring to Figure 1 , the top of the base 1 is also provided with a punching assembly 5, which is located on the side of the punching and cutting assembly 3 away from the edge folding assembly 2, and the punching assembly 5 is used for punching the U-shaped piece conveyed after being cut to a certain length.

[0062] Referring to Figure 6 , the specific structure of the punching assembly 5 is as follows:

[0063] The punching assembly 5 includes a frame 51 mounted on one side of the top of the base 1. A mounting bracket 52 and a punching seat 54 are mounted on the top of the frame 51. The punching seat 54 is located inside the mounting bracket 52. A punching slot 55 is provided on one side of the punching seat 54. Two horizontal punching cylinders 53 are horizontally mounted on both sides of the mounting bracket 52. Three vertical punching cylinders 56 are mounted on the top of the mounting bracket 52. Through holes for punching are provided on the top and side walls of the punching slot 55. The through holes extend into the interior of the punching slot 55. Punches are mounted on both the horizontal punching cylinders 53 and the vertical punching cylinders 56. A traction device is provided at the discharge port of the punching assembly 5. This traction device can be composed of an electric slide rail and an electric gripper. The electric gripper slides on the top of the electric slide rail. The electric slide rail can drive the electric gripper to move. The electric gripper is used to clamp the U-shaped part.

[0064] After being cut to a fixed length, the U-shaped part extends into the interior of the punching slot 55, and the end of the U-shaped part penetrates into the interior of the punching slot 55 and is held by an electric gripper. Subsequently, the electric slide rail drives the electric gripper to move, thereby pulling the U-shaped part. The position of the U-shaped part to be punched moves into the interior of the punching slot 55. At this time, the vertical punching cylinder 56 and the horizontal punching cylinder 53 cooperate to cause the punches installed on the vertical punching cylinder 56 and the horizontal punching cylinder 53 to perform punching operations on the position of the U-shaped part to be punched. The size of the punches installed on the vertical punching cylinder 56 and the horizontal punching cylinder 53 can be installed and replaced as needed, so that specific mounting holes or positioning holes can be punched on the U-shaped part.

[0065] Example 2, see Figure 16 and Figure 17 In the actual processing flow of U-shaped parts, after the folding process is completed, the workpiece is cut according to the production requirements to obtain a single U-shaped part that meets the length requirements. Processing obstacles often occur in this connection link. During the folding and cutting process, the U-shaped part is affected by factors such as material stress release, processing equipment accuracy deviation or uneven clamping force. Although the basic shape of the U-shaped part is not affected, its whole and sides are very prone to micro deformation, such as side expansion and port tilting.

[0066] The punching seat 54 in the punching station has a slot structure, and the punching through slot 55 has a fixed contour design. It has high requirements for the insertion posture and dimensional accuracy of the U-shaped part. When the U-shaped part with overall deformation is fed in, its deformed part will interfere with the opening position of the punching through slot 55 on the punching seat 54, causing the U-shaped part to be unable to be inserted into the punching through slot 55 smoothly. This not only requires the operator to stop the machine for manual adjustment, but may also cause the equipment to jam in severe cases, reducing the overall processing efficiency.

[0067] If the sequence of folding, punching and cutting is adopted, the problem of the overall deformation of the U-shaped piece interfering with the punching seat 54 can be avoided, but because the size of the punching through slot 55 and the profiling through slot 34 is slightly larger than the shape of the U-shaped piece, the U-shaped piece is prone to dislocation and movement during cutting, which leads to the position of the U-shaped piece fluctuating in the punching station, thereby affecting the hole position accuracy, and even causing the hole position to be inclined, directly resulting in the profile being scrapped.

[0068] Referring to Figure 1 Therefore, on the basis of adopting the sequence of folding, cutting and punching, an adapter assembly 4 is installed on the top of the base 1, the adapter assembly 4 is located between the punching and cutting assembly 3 and the punching assembly 5, the adapter assembly 4 is used to obtain the U-shaped piece cut to a fixed length, and to transfer and transport the U-shaped piece cut to a fixed length, and in this process, the overall U-shaped piece is adjusted so that the U-shaped piece can extend into the punching through slot 55.

[0069] Referring to Figures 7-9 The specific structure of the adapter assembly 4 is as follows:

[0070] The adapter assembly 4 includes a first wedge-shaped seat 41 installed on the top of the base 1 and a second wedge-shaped seat 42 sliding on the side wall of the first wedge-shaped seat 41, the top of the base 1 is hingedly installed with two transfer air cylinders 43, both of which are hingedly connected to the side wall of the second wedge-shaped seat 42, the top of the second wedge-shaped seat 42 is installed with a rolling conveying mechanism 44, a leading mechanism 47 and a guiding mechanism 49, the top of the rolling conveying mechanism 44 is symmetrically installed with two V-shaped baffles 45, when the U-shaped piece is cut to a fixed length by the punching and cutting assembly 3, the U-shaped piece will be tilted and moved downward, at this time, the U-shaped piece falls on the top of the rolling conveying mechanism 44, and the two V-shaped baffles 45 block the position of the U-shaped piece, so that the U-shaped piece is between the two V-shaped baffles 45, and then the rolling conveying mechanism 44 drives the U-shaped piece to be conveyed in the direction of the punching assembly 5.

[0071] Referring to Figure 9The top of the second wedge-shaped base 42 is provided with a rolling mechanism 46, which extends to the top of the rolling conveying mechanism 44 and is located between the V-shaped baffle 45 and the leading mechanism 47. The rolling mechanism 46 comprises a rolling frame 461 mounted on the top of the second wedge-shaped base 42 and a lifting oil cylinder 462 vertically mounted on the top of the rolling frame 461. One side of the rolling frame 461 is provided with a guide rail 463, and a sliding block 464 is slidably connected to the guide rail 463. The piston rod of the lifting oil cylinder 462 is connected to the sliding block 464. The bottom of the sliding block 464 is rotatably connected to a compression roller 465. When the U-shaped piece reaches below the rolling mechanism 46, the lifting oil cylinder 462 pushes the sliding block 464 to move downward. The sliding block 464 slides in the side wall of the guide rail 463, and the sliding block 464 drives the compression roller 465 to move downward and press on the inside of the U-shaped piece. At this time, the U-shaped piece is between the compression roller 465 and the rolling conveying mechanism 44. When the rolling conveying mechanism 44 continues to convey forward, the compression roller 465 synchronously cooperates, so that the U-shaped piece enters the inside of the leading mechanism 47, and the leading mechanism 47 adjusts the whole U-shaped piece.

[0072] When the rolling mechanism 46 and the rolling conveying mechanism 44 cooperate to convey the U-shaped piece, the guiding mechanism 49 is used to push and guide, so as to provide driving force for the adjustment of the U-shaped piece.

[0073] The specific structure of the guiding mechanism 49 is as follows:

[0074] The top of the second wedge-shaped base 42 is provided with a track 491, and the side wall of the track 491 is slidably provided with an electric moving trolley 492. The side wall of the electric moving trolley 492 is provided with a support 493, the support 493 extends to the top of the rolling conveying mechanism 44 and is provided with a guiding oil cylinder 494, and the bottom of the guiding oil cylinder 494 is connected with a guiding plate 495.

[0075] When the U-shaped piece falls on the top of the rolling conveying mechanism 44 and is conveyed forward synchronously, first, the position of the U-shaped piece is blocked by the two V-shaped baffles 45. Then, the U-shaped piece is obtained by the compression roller 465, and the U-shaped piece is conveyed between the compression roller 465 and the rolling conveying mechanism 44. At the same time, the guiding oil cylinder 494 pushes the guiding plate 495 to move downward and abut against the top of the rolling conveying mechanism 44. Then, the electric moving trolley 492 moves to the conveying direction of the U-shaped piece. The guiding plate 495 abuts against the tail of the U-shaped piece and applies a pushing force to the tail of the U-shaped piece. In cooperation with the compression roller 465 and the rolling conveying mechanism 44, the U-shaped piece can enter the inside of the leading mechanism 47.

[0076] Referring to Figures 12-15 The specific structure of the leading mechanism 47 is as follows:

[0077] The engaging mechanism 47 comprises an engaging block 471 mounted on the top of the second wedge-shaped seat 42 and an engaging slot 472 opened on one side of the engaging block 471, the inside of the engaging slot 472 is connected with a stop block 473, the sidewall of the stop block 473 is provided with a guide part 476, the size of the stop block 473 is smaller than that of the engaging slot 472, and the engaging through slot is formed between the stop block 473 and the engaging slot 472, and the size of the engaging through slot is suitable for the U-shaped piece.

[0078] The engaging slot 472 is provided with an arc part 475 on the top of one side of the rolling conveying mechanism 44, and the extending block 474 is connected to the side of the engaging block 471 away from the rolling conveying mechanism 44, and the U-shaped piece conveyed by the rolling conveying mechanism 44 is sent into the inside of the engaging slot 472.

[0079] If the U-shaped piece appears a slight deformation of inward contraction, the U-shaped piece first matches the guide part 476 after entering the inside of the engaging slot 472, and the U-shaped piece continues to be conveyed, the rolling conveying mechanism 44 continues to be conveyed and matches the compression roller 465, and then the U-shaped piece enters the engaging mechanism 47, slides on the guide part 476 and is gradually stretched, until the U-shaped piece is adjusted to the same shape as the engaging through slot, in the process, the transfer cylinder 43 pushes the second wedge-shaped seat 42 to move, the second wedge-shaped seat 42 is inclined and moves upward along the wedge-shaped surface of the first wedge-shaped seat 41, and then the extending block 474 is adjusted to the relative position of the punching seat 54, the U-shaped piece continues to be supported by the extending block 474 after passing through the engaging slot 472, the distance between the engaging block 471 and the punching seat 54 is shortened by arranging the extending block 474, the U-shaped piece directly enters the inside of the punching through slot 55 after passing through the extending block 474 and continues to be conveyed, so as to perform subsequent punching operation.

[0080] If the U-shaped piece only appears outward expansion of the top extending edge, the arc part 475 adjusts the outward expansion of the top extending edge of the U-shaped piece in the process of entering the engaging slot 472, so that the top extending edge of the U-shaped piece is inwardly contracted.

[0081] In the third embodiment, when the U-shaped piece appears a slight deformation of outward expansion of the side edge, the distance between the two side edges of the outwardly expanded U-shaped piece is greater than the suitable size of the punching through slot 55 of the punching station, and the end part contacts the entrance of the punching through slot 55, which forms a hard resistance, and even with the help of the pushing force, it is difficult to smoothly stretch into the punching through slot 55, but it may cause further deformation of the workpiece or wear of the supporting structure, and finally manual intervention is still needed, and referring to Figure 16 and Figure 17 , the U-shaped piece appears position deviation due to the influence of the punching and cutting assembly 3, and when the U-shaped piece falls on the top of the rolling conveying mechanism 44, the position deviation occurs, which not only cannot be obtained by the roller pressing mechanism 46, but also affects the entering of the U-shaped piece into the inside of the punching through slot 55.

[0082] Referring to Figure 8To this end, the positioning mechanism 48 is further installed on the top of the second wedge-shaped base 42, which is below the rolling conveying mechanism 44 and is located below the roller pressing mechanism 46. When the U-shaped piece moves below the roller pressing mechanism 46, the positioning mechanism 48 clamps the U-shaped piece, so that the position of the U-shaped piece is adjusted to be entirely below the roller pressing mechanism 46, thereby facilitating the acquisition of the roller pressing mechanism 46, and the positioning mechanism 48 can also adjust the outward expansion of the U-shaped piece. The specific structure of the positioning mechanism 48 is as follows:

[0083] Referring to Figures 10-11 The positioning mechanism 48 includes two carrier rods 481 slidingly connected to the top of the second wedge-shaped base 42. The bottom of each carrier rod 481 is connected with a guide block 488. The top of the second wedge-shaped base 42 is provided with a limiting groove. The guide block 488 is slidingly connected inside the limiting groove. One side of the two carrier rods 481 is connected with a guide groove 483. The guide groove 483 is slidingly connected with a slide column 484 inside. The end of the carrier rod 481 away from the guide groove 483 is hingedly connected with a hinge rod 482. The end of the hinge rod 482 away from the corresponding carrier rod 481 is connected with the slide column 484 on the other carrier rod 481. The two hinge rods 482 are hingedly arranged with each other. The top of the first wedge-shaped base 41 is provided with a double-acting oil cylinder 487. The two piston rods of the double-acting oil cylinder 487 are connected with the two carrier rods 481. Through the extension and retraction of the piston rod of the double-acting oil cylinder 487, the two carrier rods 481 can be driven to slide on the top of the second wedge-shaped base 42 through the corresponding guide block 488. During the process of the two carrier rods 481 moving towards each other or moving away from each other, the angle of the two hinge rods 482 changes, and at the same time, the slide column 484 slides inside the corresponding guide groove 483. The two hinge rods 482 cooperate to keep the synchronization of the movement of the two carrier rods 481 away from the end of the double-acting oil cylinder 487.

[0084] The top of each carrier rod 481 is provided with a plurality of vertical columns 485 at equal intervals. The outer side wall of each vertical column 485 is rotatably provided with a roller 486. When the U-shaped piece moves below the roller pressing mechanism 46, the two carrier rods 481 move towards each other, thereby driving the corresponding vertical columns 485 and rollers 486 to move, so that the plurality of rollers 486 clamp the side wall of the U-shaped piece. During the process of the rolling conveying mechanism 44 and the compression roller 465 cooperating to convey the U-shaped piece, the plurality of rollers 486 are affected by the movement of the U-shaped piece and rotate, so that the rollers 486 can alleviate the outward expansion of the side wall of the U-shaped piece while cooperating with the movement of the U-shaped piece.

[0085] The top of each carrier rod 481 and close to one end of the bidirectional oil cylinder 487 is hinged with a swing plate 4802, a plurality of vertical columns 485 corresponding to the carrier rod 481 are installed on the top of the swing plate 4802, the end of the carrier rod 481 away from the bidirectional oil cylinder 487 is provided with a fixing seat 489, the top of the fixing seat 489 is provided with a telescopic cylinder 4801, the piston rod of the telescopic cylinder 4801 is hinged with the top of the corresponding swing plate 4802, and the telescopic cylinder 4801 is used to drive the corresponding swing plate 4802 to swing, that is, the spacing between the two rollers 486 close to the position of the linking block 471 is shortened, and the plurality of rollers 486 on the top of the same swing plate 4802 are sequentially driven to tilt, and with the conveying of the U-shaped piece, the side wall of the U-shaped piece is pressed more when the U-shaped piece is closer to the linking block 471.

[0086] The middle part of the end of the stop block 473 close to the rolling conveying mechanism 44 is provided with a mounting groove, and an industrial camera 6 is installed in the mounting groove. The industrial camera 6 is used for visually detecting the cross-sectional shape of the cut U-shaped piece.

[0087] Specifically, after the U-shaped piece is pressed and positioned by the plurality of rollers 486, the industrial camera 6 is used for detecting the overall shape of the U-shaped piece. If the side edge of the U-shaped piece is contracted and the top extension edge is contracted or expanded, the swing plate 4802 does not need to swing, and the U-shaped piece directly enters the inside of the linking groove 472 for adjustment.

[0088] If the side edge of the U-shaped piece is expanded and slightly deformed, the telescopic cylinder 4801 corresponding to the side edge drives the corresponding swing plate 4802 to swing, so that the roller 486 further presses the side edge of the U-shaped piece, and the side edge that is expanded is further pressed inward. This setting can prevent the end of the U-shaped piece from being expanded again when it is separated from the roller 486 and has not reached the inside of the linking groove 472.

[0089] Obviously, the above-described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor should belong to the protection scope of the present application.
