Description

Technical Field

[0001] The present application relates to the technical field of forming machines, and in particular to a forming machine for processing thick profiles. Background Art

[0002] In the prior art, a forming machine is commonly used to perform cold bend forming on profiles. The forming machine usually includes a feeding workbench for conveying profiles to be bent, a forming main machine for cold bend forming the profiles, and a workbench for receiving the cold bend formed profiles.

[0003] The forming machine usually includes a frame and a plurality of forming modules arranged at intervals along the length direction of the frame. For thick profiles that need to be formed at sharp angles, they are first bent by a conventional rolling die set and then bent by an acute angle rolling die set to form the required acute angle. The acute angle rolling die set in the prior art usually includes a mounting plate placed horizontally along the width direction of the frame, two mounting parts respectively connected to the mounting plate and the frame, and two oblique pressing rollers respectively rotatably connected to the mounting parts to be staggered up and down.

[0004] During the bending process, the bending is usually performed step by step, so a number of acute angle roller pressing dies are arranged at intervals along the length direction of the frame to bend the profile, and an adjustment assembly is arranged on the frame to adjust the inclined roller in the width direction of the frame. In the prior art, the adjustment assembly specifically includes an adjustment plate fixedly connected to the lower surface of the mounting plate, a screw rod penetrating the adjustment plate to be connected to the mounting portion, and a nut threadedly connected to the screw rod. The adjustment plate is provided with a first through hole for the screw rod to pass through along the thickness, and the first through hole is arranged in the shape of a waist hole along the direction of the adjustment plate. Two nuts are provided and respectively abut against the two sides of the adjustment plate, so as to change the adjustment in the height direction.

[0005] However, for the sharp-angle folding of thick profiles of 6 mm and above, due to the large thickness of the profile, if the above-mentioned sharp-angle roller pressing die set is used, the reaction force acting on the oblique pressing roller and the corresponding adjustment component during bending is large, which may force the oblique pressing roller to slip relative to each other, thereby affecting the bending effect of the profile. And as the reaction force increases, the thick profile will be offset during the cold bending process, which also affects the bending effect of the profile, so further improvement is needed. Summary of the invention

[0006] In order to improve the stability of the sharp-angle rolling die set when bending the profile, so as to improve the bending effect of the profile, the present application provides a forming machine for processing thick profiles.

[0007] The present application provides a forming machine for processing thick profiles, which adopts the following technical solution: The present invention relates to a forming machine for processing thick profiles, comprising a feeding workbench for conveying profiles to be bent, a forming main machine for cold-bending the profiles, and a workbench for receiving the cold-bending profiles; the feeding workbench comprises a first bracket, a guide rail arranged on the first bracket, and a passive feeding trolley slidably connected to the guide rail, the passive feeding trolley is provided with a clamp for pressing against the profile, the first bracket is provided with a guide structure, the guide structure is used to drive the clamp to rotate in a direction away from the profile to release the pressing against the profile; the forming main machine comprises a frame, a conventional rolling die set and an acute-angle rolling die set arranged on the frame, and a driving mechanism arranged on one side of the frame, the conventional rolling die set is arranged at intervals along the length direction of the frame, the conventional rolling die set comprises two driven rollers and an active roller arranged opposite to each other, the middle part of the driven roller is surrounded by a groove, the active roller protrudes around a convex ring inserted in the groove, The groove depth of the groove and the diameter of the convex ring gradually increase toward the direction approaching the workbench; the acute-angle roller pressing die set is arranged at intervals along the length direction of the frame, and the acute-angle roller pressing die set includes a gantry, a support seat, an oblique pressure roller, a first adjusting screw and a third adjusting component, the gantry is provided with two horizontally placed on the frame and arranged opposite to each other, the support seat is provided with two and respectively arranged on the surfaces of the two gantries close to each other and respectively slidably connected to the two gantries, the oblique pressure roller is provided with two oblique pressure rollers respectively rotatably connected to the two support seats, the first adjusting screw is provided with two and respectively threadedly penetrated through the gantry to connect with the support seat, and the third adjusting component is arranged on the frame to adjust the height position of the gantry; the driving mechanism is used to drive the active roller to rotate, the two oblique pressure rollers are arranged in an alternating radial direction, and a gap is left between the two oblique pressure rollers for the profile to pass through, and the frame is also provided with a third adjusting component for adjusting the height position of the driven roller.

[0008] By adopting the above technical solution, before the profile is fed into the forming main machine for cold bending, the profile is first pressed against the passive feeding trolley by the clamp. As the subsequent forming machine drives the profile forward, the passive feeding trolley is connected to the guide rail by sliding to slide along the length direction of the bracket, thereby driving the passive feeding trolley to move toward the forming machine, which can reduce the possibility of displacement of the profile in the height direction during the feeding process, so as to improve the bending effect of the profile. As the feeding increases, the clamping capacity is limited. Therefore, when the passive feeding trolley is driven to the guide structure, it drives the clamp to rotate in the direction away from the profile to release the pressing of the profile, so that the remaining profile can be bent. Then the staff pushes the passive trolley to the end of the bracket away from the forming machine, and then presses the next profile with the clamp, and repeats the cycle.

[0009] Then, through the conventional roller pressing die set, through the convex ring on the active roller and the matching groove on the driven roller, as the groove depth and the diameter of the convex ring gradually increase towards the direction close to the workbench, the middle part of the profile is arched in an arc shape and gradually forms an inverted U-shaped convexity. When it is transmitted to the acute angle roller pressing die set, it passes through the oblique pressing roller so that the edge of the inverted U-shaped convexity is set in a V shape. Since the oblique pressing roller is first rotated and connected to the support seat and then connected to the gantry, it can provide a relatively high load-bearing capacity during the bending process of the thick profile, thereby improving the strength of the acute angle roller pressing die set, so that it is suitable for bending some thicker profiles. And by adjusting the height of the gantry by adjusting the assembly, rather than directly adjusting the adjustment plate set on the oblique pressing roller, the possibility of the oblique pressing roller slipping due to the reaction force of the profile can be reduced, thereby improving the stability of the acute angle roller pressing die set when bending the profile, so as to improve the bending effect of the profile.

[0010] Preferably, the axes of the oblique pressing rollers in two adjacent acute-angle rolling die sets are staggered, and at least one conventional rolling die set is arranged between every two sets of acute-angle rolling die sets.

[0011] By adopting the above technical solution, two axes are staggered and the oblique pressing rollers are arranged so that the width of the upper end of the protrusion is greater than the width of the lower end thereof, thereby forming an Ω shape. At least one conventional rolling die set is arranged between each two sets of acute angle rolling die sets, so as to position the profile while conveying it, reduce the possibility of horizontal displacement when cold bending at the acute angle rolling die set, and improve the bending effect of the profile.

[0012] Preferably, the gantry includes a second transverse plate for the support seat to slide, a plurality of fourth fixed plates perpendicular to the second transverse plate, away from the support seat and arranged in parallel, and two vertical plates respectively arranged at both ends of the second transverse plate, the two ends of the fourth fixed plate are respectively fixedly connected to the vertical plates, the first adjusting screw is passed through the lower end of the vertical plate and exposed from the vertical plate, the third adjusting component is arranged on the vertical plate, and the number of the third adjusting components is the same as the number of the vertical plates; the lower surface of the second transverse plate located in the middle is provided with a sliding groove along its own length direction, the cross-section of the sliding groove is rectangular, the upper end of the support seat is slidably connected to the sliding groove, the second transverse plate is provided with a fixing part for fixing the support seat, and the first adjusting screw is detachably connected to the support seat.

[0013] By adopting the above technical solution, the second horizontal plate is used for the support seat to slide, and the vertical plate is used for the installation of the third adjustment component, so that the staff can adjust the diagonal pressure roller by adjusting the vertical plate, and the fixed plate is set to further improve the strength of the gantry, wherein the first adjustment screw is passed through the lower end of the vertical plate and exposed on the vertical plate, so that the staff can adjust the position of the support seat in the width direction of the frame. By opening a slide groove along the length direction of the lower surface of the second horizontal plate in the middle for the support seat to slide, the slide groove is set in a rectangular shape, and the difficulty of opening the groove and the difficulty of setting the corresponding support seat are reduced compared to the slide groove set in a T shape. Then, it is fixed by a fixing piece, and the slide groove and the first adjustment screw are detachably connected to the support seat, so as to facilitate the removal of the worn diagonal pressure roller.

[0014] Preferably, the frame is provided with a third sliding plate for sliding connection of the vertical plate, and the third sliding plate is provided with two and is respectively arranged on the opposite side walls of the vertical plate; the two vertical plates located on one side are respectively the first vertical plate and the second vertical plate from top to bottom, and the corresponding third adjustment components are respectively the fourth adjustment component and the fifth adjustment component from top to bottom, and the fourth adjustment component includes an abutment plate detachably connected to the upper surface of the first vertical plate, a second mounting plate arranged on the two sliding plates, a hand-cranked screw lifter fixedly connected to the second mounting plate, and a screw rod lifter connected between the two sliding plates. The cam is an adjustable speed gear, and the adjustable speed gear is connected to the second adjusting cam, and the adjustable speed gear is connected to the second adjusting cam, and the adjustable speed gear is connected to the second adjusting cam, and the adjustable speed gear is connected to the second adjusting cam.

[0015] By adopting the above technical solution, the hand-cranked screw lifter is started to drive the upper gantry to adjust its height position, and then the first limit rod is used to change the height adjustment of the upper inclined pressure roller. When adjusting the lower gantry, the second limit rod is first rotated to limit the height direction, and then the gantry is moved. The nut below is rotated to abut against the second vertical plate to adjust the height of the lower gantry. Compared with the adjustment method in the prior art, this adjustment method is more stable and is not prone to displacement due to the reaction force during the cold bending process of the profile.

[0016] Preferably, the upper surface of the passive feeding trolley is provided with a plurality of first positioning rollers on both sides of the profile, and the passive trolley is provided with a first adjusting component for adjusting the spacing between the first positioning roller and the profile; the passive sliding trolley includes a sliding seat slidably connected to the guide rail and a base plate arranged on the sliding seat, and the lower surface of the base plate is provided with a first mounting plate for the first adjusting component, and the first mounting plate is provided with two and is arranged near the two sides of the base plate. The first adjusting component includes a first screw rod rotatably penetrated through one of the first mounting plates and rotatably connected to the other first mounting plate, two first sliding plates both slidably connected to the base plate, and a first driving member that drives the first screw rod to rotate forward or reverse. The first screw rod is a bidirectional threaded screw rod, and the first screw rod is threadedly penetrated through the two first sliding plates, and the lower end of the first positioning roller protrudes with a fixing rod connected to the first sliding plate, and the upper surface of the base plate is penetrated along its width direction with a first through groove for the fixing rod to pass through, and a plurality of fixing rods located on one side are fixedly connected to the same first sliding plate.

[0017] By adopting the above technical solution, the first driving member is started to drive the first screw to rotate. Since the first screw is a bidirectional threaded screw, it drives the first sliding plates on both sides to move towards or away from each other, so as to press the profile to limit it or adjust it according to the profile. Moreover, since several fixed rods located on one side are fixedly connected to the same first sliding plate, several first positioning rollers are driven to adjust with the sliding of the first sliding plate, thereby reducing the time spent on adjusting several first positioning rollers and the corresponding adjustment difficulty, and can speed up the positioning rate of the profile to reduce the impact on the overall work efficiency.

[0018] After the profile is pressed against the passive feeding trolley by the clamp, as the subsequent forming machine drives the profile forward, the passive feeding trolley is slidably connected to the guide rail to slide along the length direction of the first bracket, thereby driving the first positioning roller provided on the passive feeding trolley to position itself in the process of moving toward the forming machine, reducing the adjustment time and difficulty caused by the need to set up several correction components, thereby further accelerating the positioning rate of the profile and reducing the impact on the overall work efficiency.

[0019] Preferably, the clamp is arranged near the guide structure, and the clamp comprises a first fixed plate arranged on the first sliding plate, a second fixed plate vertically connected to the first fixed plate, a handle hinged at the lower end of the second fixed plate, a mounting rod hinged at the upper end of the second fixed plate, and a fastening member arranged at an end of the mounting rod away from the second fixed plate; a fourth through-slot is penetrated through the upper surface of the bottom plate for the second fixed plate and the handle to pass through, the length direction of the handle is parallel to the height direction of the second fixed plate, the mounting rod is hinged with a hinged rod hinged with the handle, and the hinge point between the handle and the mounting rod is diagonally arranged, and the guide structure is used to drive the handle to rotate along the hinge point hinged with the second fixed plate; a connecting plate is slidably connected to the upper surface of the first sliding plate, and several of the fixing rods are connected to the connecting plate, and the handle is hinged with a push rod, the length direction of the push rod is parallel to the length direction of the second fixed plate, the push rod is slidably connected to the second fixed plate, and the end of the push rod away from the handle is connected with a connecting rod connected to the connecting plate.

[0020] By adopting the above technical solution, the fixing rod is directly fixedly connected to the first sliding plate, and the first driving member may need to be started twice to respectively drive the first positioning roller to move in the direction away from the profile to provide a placement space for the profile and drive the first positioning roller to abut against the profile for positioning, and the corresponding number of operations is increased. Therefore, by providing a connecting plate that is slidingly connected to the first sliding plate and a connecting rod that is hinged to the handle, when the guide structure drives the handle to move in the direction away from the profile, the connecting plate, the fixing rod and the first positioning roller can be driven to move in the direction away from the profile in sequence to provide a placement space for the subsequent profile, and when the handle is pushed to move in the direction close to the profile to abut the abutting member against the profile, the first positioning roller can be driven to move in the direction close to the profile to limit the height direction and the horizontal direction at the same time, thereby reducing the number of operation steps and accelerating the positioning rate of the profile. And the clamp is set on the first sliding plate, and the first sliding plate can be adjusted when it is displaced in the width direction of the first bracket with the rotation of the first screw rod, so as to limit the profile in the width direction.

[0021] Preferably, the connecting rod specifically includes a first connecting rod connected to the push rod, a second connecting rod perpendicular to the first connecting rod, a third connecting rod perpendicular to the second connecting rod and parallel to the first connecting rod, and a sleeve slidably sleeved on the third connecting rod, the second connecting rod is protrudingly provided with a second limit block, the inner wall of the sleeve is provided with a limit groove for sliding connection of the second limit block, and the sleeve is connected to the first sliding plate.

[0022] By adopting the above technical solution, when the clamp is unlocked and pressed against the profile, and when the clamp has not rotated to drive the push sleeve and the second push rod to move away from the profile, the first positioning roller can also be positioned during the process of the profile being pulled by the subsequent forming main machine.

[0023] Preferably, the base plate is provided with a control rod slidably inserted into the first through groove, a guide block is protruding from the upper surface of the connecting rod, a second guide surface is provided on the surface of the guide block close to the connecting rod, and a third guide surface is provided at the lower end of the control rod which is slidably connected to the second guide surface.

[0024] By adopting the above technical solution, when the handle moves along with the guide structure to drive the clamping piece in the direction away from the profile, the clamping of the profile is unlocked, and then the first positioning roller is driven to move in the direction away from the profile. A guide block is provided, a first guide surface is provided on the guide block, and a second guide surface is provided at the lower end of the control rod. With the sliding connection between the first guide surface and the second guide surface, the control rod is driven to rise. When the profile is moved next time, after a force is applied to the control rod, with the cooperation between the first guide surface and the second guide surface, a reaction force is exerted on the handle to push the clamping piece against the profile, and the first positioning roller can be driven to move in the direction of the profile for positioning.

[0025] Preferably, the abutting member includes an abutting rod abutting against the upper surface of the profile and an isolation strip arranged on the lower surface of the abutting rod, the isolation strip is elastic, and the length direction of the abutting rod is parallel to the width direction of the profile.

[0026] By adopting the above technical solution, by providing an abutment rod and an isolation strip on the abutment rod, the possibility of the profile being pulled when abutting or being scratched due to excessive abutment force can be reduced, and the isolation strip can also be pressed to a certain extent when abutting against the profile, thereby enhancing the positioning effect of the profile and reducing vibration during the feeding process.

[0027] Preferably, a reset assembly for driving the passive feeding trolley to reset is provided on the first bracket, and the reset assembly includes a rotating rod rotatably connected to the first bracket, a connecting rope connected to the rotating rod and connected to the sliding seat, and a second driving member for driving the rotating rod to rotate forward or reverse, and the connecting rope is used to be wound around the rotating rod.

[0028] By adopting the above technical solution, the second driving member is started. When the rotating rod rotates forward, the connecting rope is unwound so that the passive feeding trolley can move with the transmission of the profile. When it moves to the guide structure to unlock the clamp, the second driving member is started to drive the rotating rod to reverse, thereby rewinding the connecting rope to reset the passive feeding trolley to feed the next profile.

[0029] In summary, this application has the following beneficial effects: After the profile is pressed against the passive feeding trolley by the clamp, as the subsequent forming machine drives the profile forward, the passive feeding trolley is connected to the guide rail by sliding, so as to slide along the length direction of the bracket, thereby driving the passive feeding trolley to move toward the forming machine, which can reduce the possibility of displacement of the profile in the height direction during the feeding process, so as to improve the bending effect of the profile. And because the oblique pressure roller is first rotated and connected to the support seat, and then connected to the gantry, it can provide a relatively high load-bearing capacity during the bending process of thick profiles, thereby improving the strength of the acute angle roller pressing die set, so as to be suitable for bending some thicker profiles. And by adjusting the height of the gantry by adjusting the assembly, rather than directly adjusting the adjustment plate set on the oblique pressure roller, the possibility of the oblique pressure roller slipping due to the reaction force of the profile can be reduced, thereby improving the stability of the acute angle roller pressing die set when bending the profile, so as to improve the bending effect of the profile.

At this time, two mounting bolts 83 are provided and are arranged on both sides of the width direction close to the abutment plate 811.

The second mounting plate 812 is fixedly connected to the upper surfaces of the two sliding plates. The hand-cranked screw lifter 813 is fixedly connected to the second mounting plate 812.

A connecting shaft 816 is provided between the two hand-cranked screw lifts 813, and the axis of the connecting shaft 816 is parallel to the handwheel in the hand-cranked lift, so that the other hand-cranked screw lift 813 does not need to be provided with a handwheel, thereby reducing the corresponding cost.

[0055] Among them, the two ends of the first limiting plate 814 are arranged between the two third sliding plates 311 and below the first vertical plate 3314. The first limiting plate 814 protrudes from the third sliding plate 311 and abuts against the third sliding plate 311 away from the surface of the support seat 332. Then the two third sliding plates 311 are fixedly connected by installing bolts 83 and nuts 84. Two first limiting rods 815 are arranged at intervals along the length direction of the upper end surface of the first limiting plate 814. In this embodiment, the first limiting rod 815 can be threaded through the first limiting plate 814, or it can be connected by threading with a nut 84. In this embodiment, it is specifically demonstrated with a nut 84 threadedly connected. Specifically, the first limiting rod 815 is penetrated by the first limiting plate 814. The first limiting rod 815 is penetrated by the first limiting rod 815 to abut against the lower end surface of the first vertical plate 3314. The first limiting rod 815 is also threadedly connected with a nut 84. At this time, the nut 84 abuts against the lower surface of the first limiting plate 814.

[0056] Among them, the fifth adjustment component 82 specifically includes a second adjustment screw 821 fixedly connected to the upper surface of the frame 31 and passed through the lower surface of the second vertical plate 3314, an adjustment nut 822 threadedly connected to the second adjustment screw 821 to abut against the second vertical plate 3314, a second limit plate 823 connected between the two sliding plates, and a second limit rod 824 threadedly passed through the second limit plate 823 to abut against one end of the second vertical plate 3314 away from the screw rod.

[0057] When it is transferred to the acute angle roller pressing die set 33, the inclined pressing rollers 333 are arranged in a staggered manner with two axes, so that the raised edge of the inverted U-shape is arranged in a V-shape, so that the width of the upper end of the raised edge is greater than the width of the lower end. At least one conventional roller pressing die set 32 ​​is arranged between each two sets of acute angle roller pressing die sets 33, so as to position the profile 1 while transferring it, reduce the possibility of horizontal displacement when cold bending at the acute angle roller pressing die set 33, so as to improve the bending effect of the profile 1, and with the subsequent rolling of several conventional roller pressing dies 32, the raised middle part of the profile 1 is formed into an Ω shape, and then it is transferred to the forming of the profile 1, which can be referred to Fig.11 to view it.

[0058] It should be noted that the axes of the oblique pressing rollers 333 in two adjacent acute angle pressing dies 33 are staggered, and at least one conventional pressing die set 32 ​​is arranged between each two sets of acute angle pressing dies 33. This allows the profile 1 to be positioned while being conveyed, reduces the possibility of horizontal displacement during cold bending at the acute angle pressing die set 33, and improves the bending effect of the profile 1.

[0059] The implementation principle of a forming machine for processing thick profiles in an embodiment of the present application is as follows: first, the profile 1 is pressed against the passive feeding trolley 23 by the clamp 6, and then as the subsequent forming machine drives the profile 1 forward, the passive feeding trolley 23 is slidably connected to the guide rail 22 to slide along the length direction of the bracket, thereby driving the passive feeding trolley 23 to move toward the forming machine, which can reduce the possibility of height displacement of the profile 1 during the feeding process, thereby improving the bending effect of the profile 1. Then, it passes through the conventional roller pressing die set 32, through the convex ring 3221 on the active roller 322 and the matching groove 3211 on the driven roller 321, and as the groove depth of the groove 3211 and the diameter of the convex ring 3221 gradually increase toward the direction close to the workbench 4, so that the middle part of the profile 1 is arched in an arc shape, and gradually forms an inverted U-shaped convexity, and when it is transmitted to the acute angle roller pressing die set 33, it passes through the oblique pressing roller 333, so that the convex edge of the inverted U-shaped convexity is set in a V shape. Since the oblique pressing roller 333 is first rotated and connected to the support seat 332, and then connected to the gantry 331, it can provide a relatively high load-bearing capacity during the bending process of the thick profile 1, thereby improving the strength of the acute angle roller pressing die set 33, so that it is suitable for bending some thicker profiles 1. By adjusting the height of the gantry 331 through an adjusting assembly, rather than directly adjusting the adjusting plate disposed on the oblique pressing roller 333 , the possibility of the oblique pressing roller 333 slipping due to the reaction force of the profile 1 can be reduced, thereby improving the stability of the acute angle rolling die set 33 when bending the profile 1, thereby improving the bending effect of the profile 1 .

The length direction of the handle 63 is parallel to the height direction of the second fixed plate 62.
