Description

Technical Field

[0001] This application relates to the technical field of shaping and processing, and in particular to a high-strength acute angle forming module. Background Art

[0002] When bending profiles, a roll-forming machine is commonly used for cold bending. For profiles that require acute angle forming, corresponding acute angle forming modules are needed. The existing acute angle forming modules include a mounting plate horizontally placed along the width direction of the frame, two mounting parts respectively connected to the mounting plate and the frame, and two diagonal pressure rollers respectively rotatably connected to the mounting parts and arranged in a vertically staggered manner.

[0003] During the bending process, it is usually bent step by step. Therefore, several acute angle forming modules are arranged at intervals along the length direction of the frame to bend the profile, and an adjustment component is arranged on the frame to adjust the positions of the inclined rollers in the width direction and height direction of the frame. The adjustment component specifically includes an adjustment plate fixedly connected to the lower surface of the mounting plate, a screw rod passing through the adjustment plate and connected to the mounting part, and a nut threadedly connected to the screw rod. The adjustment plate is provided with a through hole for the screw rod to pass through along the thickness, and the through hole is arranged as a waist-shaped hole along the direction of the adjustment plate. There are two nuts respectively abutted against both sides of the adjustment plate, so as to change the adjustment in the height direction.

[0004] However, when folding the edges of thick profiles of 6 mm or more, due to the large thickness of the profile, if the above-mentioned acute angle forming module is used, the reaction force acting on the diagonal pressure roller and the corresponding adjustment component during bending is relatively large, which may force the diagonal pressure roller to slip relatively, thereby affecting the bending effect of the profile. Therefore, further improvement is needed. Utility Model Content

[0005] In order to improve the stability of the acute angle forming module during profile bending and improve the bending effect of the profile, this application provides a high-strength acute angle forming module.

[0006] A high-strength acute angle forming module provided by this application adopts the following technical solutions:

[0007] A high-strength acute angle forming module includes two gantry frames horizontally placed on the frame and arranged oppositely, two support seats arranged between the two gantry frames and respectively slidably connected to the two gantry frames, two diagonal pressure rollers respectively rotatably connected to the support seats, two first adjustment screw rods respectively threadedly passing through the gantry frames and connected to the support seats, and an adjustment component arranged on the frame to adjust the height of the gantry frame; the radial directions of the two diagonal pressure rollers are arranged in a staggered manner, and a gap is left between the two diagonal pressure rollers for the profile to pass through.

[0008] By adopting the above technical solution, after the skew roller is first rotatably connected to the support seat and then connected to the gantry, a relatively high bearing capacity can be provided during the bending process of thick profiles, thereby improving the strength of the acute angle forming module to be applicable to the bending of some thick profiles. And by adjusting the component to adjust the height of the gantry, rather than directly adjusting the adjusting plate arranged on the skew roller, the possibility of the skew roller slipping due to the reaction force of the profile can be reduced, thereby improving the stability of the acute angle forming module during the bending of the profile and improving the bending effect of the profile.

[0009] Preferably, the gantry includes a cross plate for the support seat to slide, several fixing plates perpendicular to the cross plate and parallel to each other away from the support seat, and two vertical plates respectively arranged at both ends of the cross plate. Both ends of the fixing plate are fixedly connected to the vertical plates. The first adjusting screw penetrates through the lower end of the vertical plate and is exposed outside the vertical plate. The adjusting component is arranged on the vertical plate, and the number of the adjusting components is the same as the number of the vertical plates.

[0010] By adopting the above technical solution, the cross plate is used for the support seat to slide, and the vertical plate is used for installing the adjusting component, so that the staff can adjust the skew roller by adjusting the vertical plate. The arranged fixing plate further improves the strength of the gantry. Among them, the first adjusting screw penetrates through the lower end of the vertical plate and is exposed outside the vertical plate, so that the staff can adjust the position of the support seat in the width direction of the frame.

[0011] Preferably, there are two fixing plates. The gantry further includes a reinforcing plate fixedly connected between the two fixing plates, and several reinforcing plates are arranged at intervals along the length direction of the fixing plate.

[0012] By adopting the above technical solution, the arranged reinforcing plate improves the connection strength between the two fixing plates and can also improve the bearing capacity of the gantry for the reaction force generated during the bending process of the profile.

[0013] Preferably, a chute is opened on the lower surface of the middle part of the cross plate along its own length direction. The cross section of the chute is rectangular. The upper end of the support seat is slidably connected to the chute. The cross plate is provided with a fixing member for fixing the support seat, and the first adjusting screw is detachably connected to the support seat.

[0014] By adopting the above technical solution, a chute is opened on the lower surface of the middle part of the cross plate along its length direction for the support seat to slide. By setting the chute to be rectangular, the grooving difficulty and the setting difficulty of the corresponding support seat are both reduced compared with the chute arranged in a T shape. Then, it is fixed by the fixing member. And in cooperation with the chute, and the first adjusting screw is detachably connected to the support seat, so as to facilitate the disassembly of the worn skew roller.

[0015] Preferably, the fixing member is a fixing bolt passing through the transverse plate, the fixing bolt is threadedly connected to the support base, the transverse plate is provided with a through hole for the fixing bolt to pass through, the through hole is arranged as an oblong hole, and the length direction of the through hole is parallel to the length direction of the first adjusting screw.

[0016] By adopting the above technical solution, the fixing bolt locks the support base on the transverse plate, that is, on the gantry. Since the support base slides along the length direction of the transverse plate, the through hole is correspondingly arranged as an oblong hole for the corresponding adjustment of the fixing bolt.

[0017] Preferably, an installation seat is fixedly connected to the side wall of the support base close to the first adjusting screw. The upper surface of the installation seat is provided with a limiting groove with a T-shaped cross section along its height direction, and the limiting groove extends to the side wall of the installation seat close to the first adjusting screw. The first adjusting screw is provided with a limiting block slidably inserted into the limiting groove.

[0018] By adopting the above technical solution, by providing an installation seat, the installation seat is provided with a limiting groove with a T-shaped cross section along its height direction, so as to replace the inclined pressure roller after it is damaged, and it can also reduce the possibility that the inclined pressure roller causes relative sliding of the support base under the reaction of the profile.

[0019] Preferably, the frame is provided with sliding plates for the vertical plates to slidably connect. There are two sliding plates and they are respectively arranged on the opposite side walls of the vertical plate; the two vertical plates on one side are the first vertical plate and the second vertical plate from top to bottom, and the corresponding adjusting components are the first adjusting component and the second adjusting component from top to bottom. The first adjusting component includes a butting plate detachably connected to the upper surface of the first vertical plate, mounting plates arranged on the two sliding plates, a hand-operated screw jack fixedly connected to the mounting plates, a first limiting plate connected between the two sliding plates, and a first limiting rod threadedly passing through the first limiting plate to abut against the end of the first vertical plate away from the screw; the screw of the hand-operated screw jack passes through the mounting plate and is fixed to the butting plate; the second adjusting component includes a second adjusting screw fixedly connected to the upper surface of the frame and passing through the lower surface of the second vertical plate, a nut threadedly connected to the second adjusting screw to abut against the second vertical plate, a second limiting plate connected between the two sliding plates, and a second limiting rod threadedly passing through the second limiting plate to abut against the end of the second vertical plate away from the screw.

[0020] By adopting the above technical solution, start the hand-cranked screw lift to drive the gantry above to adjust the height position. Then, use the first limit rod to change the adjustment of the upper diagonal pressure roller in the height direction. When adjusting the lower gantry, specifically, first limit the height by rotating the second limit rod, then move the gantry, and finally rotate the lower nut until it abuts against the second vertical plate to adjust the height of the lower gantry.

[0021] Preferably, a connecting shaft is arranged between the two hand-cranked screw lifts, and the axis of the connecting shaft is parallel to the handwheel in the hand-cranked screw lift.

[0022] By adopting the above technical solution, by arranging a connecting shaft, after rotating one handwheel, the height positions of the two first vertical plates can be adjusted. The adjustment is relatively precise, with a high levelness, and the operation time required can be reduced.

[0023] In summary, the utility model has the following beneficial effects:

[0024] After the diagonal pressure roller is first rotatably connected to the support seat and then connected to the gantry, a relatively high bearing capacity can be provided during the bending process of thick profiles, so as to improve the strength of the acute angle forming module and be applicable to the bending of some thick profiles. And by adjusting the height of the gantry through the adjusting component instead of directly adjusting the adjusting plate arranged on the diagonal pressure roller, the possibility of the diagonal pressure roller slipping due to the reaction force of the profile can be reduced, thereby improving the stability of the acute angle forming module during the bending of the profile and improving the bending effect on the profile.

In this embodiment, the radial directions of the two inclined pressure rollers 4 are arranged in a staggered manner, and a gap is left between the two inclined pressure rollers 4 for the profile to pass through.

[0034] Among them, the gantry 2 specifically includes a cross plate 21, a fixing plate 22, a reinforcing plate 23, and a vertical plate 24. In this embodiment, the cross plate 21 is horizontally placed on the frame 1, and the length direction of the cross plate 21 is parallel to the width direction of the frame 1. A plurality of fixing plates 22 are arranged and perpendicular to the upper surface of the cross plate 21. Specifically, two fixing plates 22 are provided, and the length direction of the fixing plates 22 is parallel to the length direction of the cross plate 21. The reinforcing plate 23 is arranged between the two fixing plates 22 and is fixed to the fixing plates 22 and the cross plate 21. In this embodiment, two vertical plates 24 are provided and are respectively fixedly connected to both ends of the cross plate 21. The length direction of the vertical plates 24 is perpendicular to the length direction of the cross plate 21, and both ends of the fixing plates 22 are respectively fixedly connected to the vertical plates 24.

[0035] Wherein, sliding grooves 211 are formed on the surfaces of the two transverse plates 21 close to each other. In this embodiment, the cross-section of the sliding groove 211 is rectangular. The upper end of the support base 3 is slidably connected to the sliding groove 211, and the transverse plate 21 is provided with a fixing member 212 for fixing the support base 3. In this embodiment, the fixing member 212 is specifically a fixing bolt passing through the transverse plate 21, and the fixing bolt is threadedly connected to the support base 3. The transverse plate 21 is provided with a through hole 213 for the fixing bolt to pass through, and the through hole 213 is in the shape of a waist-shaped hole. The length direction of the through hole 213 is parallel to the length direction of the transverse plate 21. In this embodiment, three fixing bolts are arranged at intervals along the length direction of the transverse plate 21, and two fixing bolts are arranged along the width direction of the transverse plate 21 to improve the fixing effect on the support base 3.

[0036] Referring to Figure 2 、 Figure 3 Among them, the first adjusting screw rod 5 passes through the lower end of the vertical plate 24 and is exposed outside the vertical plate 24. The first adjusting screw rod 5 is detachably connected to the support base 3. Specifically, an installation seat 31 is arranged on the side wall of the support base 3 close to the first adjusting screw rod 5. An installation bolt 7 is threadedly inserted through the installation seat 31, and the installation bolt 7 is threadedly connected to the side wall of the support column. Two installation bolts 7 are arranged at intervals along the length direction of the installation seat 31. In this embodiment, a limiting groove 311 with a T-shaped cross-section is formed through the upper surface of the installation seat 31 along its height direction, and the limiting groove 311 extends to the side wall of the installation seat 31 close to the first adjusting screw rod 5. A limiting block 51 slidably inserted into the limiting groove 311 protrudes from the first adjusting screw rod 5. Since the first adjusting screw rod 5 is threadedly inserted through the vertical plate 24, the limiting block 51 is a boss with a T-shaped cross-section.

[0037] Referring to Figure 2 、 Figure 4 Among them, the adjusting assembly 6 is arranged on the vertical plate 24, and the number of the adjusting assemblies 6 is the same as that of the vertical plates 24. The frame 1 is provided with a sliding plate 11 for the vertical plate 24 to be slidably connected.

The two sliding back plates are respectively arranged on the opposite side walls of the vertical plate 24, and two vertical plates 24 are slidably connected between the two sliding plates 11. The lower end of the sliding plate 11 is fixedly connected to the upper surface of the frame 1.

[0039] Among them, the first adjustment component 61 includes a contact plate 611, a mounting plate 612, a hand-cranked screw jack 613, a first limiting plate 614 and a first limiting rod 615. The contact plate 611 is fixedly connected to the upper surface of the first vertical plate 241 through mounting bolts 7. At this time, two mounting bolts 7 are provided and are arranged near both sides of the contact plate 611 in the width direction. The contact plate 611 is detachably connected to the first vertical plate 241 through the mounting bolts 7. The mounting plate 612 is fixedly connected to the upper surfaces of the two sliding plates 11. The hand-cranked screw jack 613 is fixedly connected to the mounting plate 612. Since the hand-cranked screw jack 613 is a prior art, it will not be elaborated here. The screw rod in the hand-cranked screw jack 613 rotates through the mounting plate 612 and is fixedly connected to the contact plate 611. A connecting shaft 616 is arranged between the two hand-cranked screw jacks 613. The axis of the connecting shaft 616 is parallel to the handwheel in the hand-cranked screw jack 613. Thus, a handwheel does not need to be provided on the other hand-cranked screw jack 613, reducing the corresponding cost.

[0040] Among them, both ends of the first limiting plate 614 are arranged between the two sliding plates 11 and are arranged below the first vertical plate 241. The first limiting plate 614 protrudes from the sliding plate 11 and abuts against the surface of the sliding plate 11 away from the support base 3. Then, the two sliding plates 11 are fixedly connected through the mounting bolts 7 and nuts 8. Two first limiting rods 615 are arranged at intervals along the length direction of the upper end surface of the first limiting plate 614. In this embodiment, the first limiting rod 615 can be threadedly inserted into the first limiting plate 614 or can be threadedly connected with a nut 8. In this embodiment, specifically, the threaded connection with the nut 8 is shown. The first limiting rod 615 is inserted through the first limiting plate 614 and the first limiting rod 615 is inserted through the first limiting rod 615 to abut against the lower end surface of the first vertical plate 241.

The second limiting rod 624 is arranged in the same way as the first limiting rod 615 and will not be elaborated here.

[0042] The implementation principle of a high-strength acute angle forming module in an embodiment of this application is as follows: After the diagonal pressure roller 4 is rotatably connected to the support base 3 first, it is then connected to the gantry 2. During the process of bending thick profiles, it can provide a relatively high load-bearing capacity, thereby improving the strength of the acute angle forming module to be applicable to bending some thick profiles. And by adjusting the component 6 to adjust the height of the gantry 2 instead of directly adjusting the adjusting plate provided on the diagonal pressure roller 4, the possibility of the diagonal pressure roller 4 slipping due to the reaction force of the profile can be reduced, thereby improving the stability of the acute angle forming module when bending the profile and improving the bending effect on the profile.

[0043] The above are all preferred embodiments of this application.
