Description

Technical Field

[0001] The present application relates to the technical field of roll forming, and in particular to a metal sandwich panel roll forming device. Background Art

[0002] Metal sandwich panels are a type of structural material that consists of two metal outer layers sandwiching a layer of sandwich material in the middle. In order to increase the bending stiffness and strength of metal sandwich panels, so that they can withstand greater loads and maintain a stable shape, roll forming is usually used to process metal sandwich panels into a wavy shape during the production process of metal sandwich panels. In addition, the wavy metal sandwich panels can also increase their own anti-extrusion and energy absorption capabilities, making them perform better when subjected to impact or compression forces.

[0003] Referring to the Chinese patent document with authorization announcement number CN116748354B and announcement date October 20, 2023, entitled "A rolling device for forming color steel plates", the device comprises a frame and several groups of rolling groups installed on the frame, which can roll the color steel plates into shape through lower rollers and upper rollers inside the multiple groups of rolling groups.

[0004] With reference to the above technical scheme, when the metal sandwich panel is roll-formed, since the metal sandwich panel is usually wound around the winding roller in a coiled manner in the initial state, when the metal sandwich panel is unrolled and enters the rolling gap between the upper and lower rollers, the unrolled end of the metal sandwich panel may be warped to a certain extent due to the curling stress during rolling, which may easily cause the unrolled end of the metal sandwich panel to fail to accurately enter the rolling gap between the upper and lower rollers; after the metal sandwich panel has completed a certain length of rolling, the rolling and conveying work of the metal sandwich panel needs to be suspended, and then the metal sandwich panel of this part is cut off. During this process, the metal sandwich panel still located in the rolling gap may shake and deviate in the conveying direction due to the impact force generated during cutting, which may easily affect the subsequent rolling quality of the metal sandwich panel. Summary of the invention

[0005] In view of this, the present application provides a metal sandwich panel roll-forming device, which is mainly used to solve the problem that the unwinding end of the metal sandwich panel is difficult to accurately enter the rolling gap due to warping.

[0006] In order to solve the above-mentioned technical problems, the present application provides a metal sandwich panel roll-forming device, comprising a conveyor, a plurality of roller groups arranged in groups of two inside the conveyor, and a cutter arranged at the unloading port of the conveyor; the front and rear inner walls of the conveyor loading port are each provided with two upper and lower symmetrical guide springs, and a gap is reserved between the upper and lower guide springs for the metal sandwich panel to pass through, and the guide springs are composed of a horizontal plate fixedly connected to the inner wall of the conveyor and a warping plate abutting against the inner wall of the conveyor; each guide spring is slidably connected to a pressure wheel via a first elastic member, and a pushing member is provided between the conveyor and the cutter, for making the pressure wheel move away from the horizontal plate while approaching the warping plate.

[0007] By adopting the above technical scheme, the guiding effect and pre-flattening effect of the guide spring sheet are utilized, so that the unwinding end of the metal sandwich panel can enter the rolling gap more accurately, thereby reducing the probability that the unwinding end of the metal sandwich panel cannot accurately enter the rolling gap due to warping; at the same time, the guide spring sheet can clamp and fix the metal sandwich panel during the cutting process to prevent the metal sandwich panel still located in the rolling gap from shaking and deviating.

[0008] Optionally, each of the horizontal plates is provided with a plurality of grooves, and a rolling ball is rotatably connected in each groove for replacing the horizontal plate in contact with the metal sandwich panel, and each warping plate is provided with a rubber strip for replacing the horizontal plate in contact with the metal sandwich panel.

[0009] By adopting the above technical solution, the rolling balls and rubber strips are used to reduce the probability of the metal sandwich panel being scratched or pinched.

[0010] Optionally, the depth of each groove is greater than the radius of the rolling ball and less than the diameter of the rolling ball.

[0011] By adopting the above technical solution, under the premise that the rolling balls replace the horizontal plates to contact the metal sandwich panels, the distance between the metal sandwich panels and the horizontal plates can be shortened as much as possible to prevent the metal sandwich panels from being stuck in the gap between two adjacent rolling balls and affecting the normal transportation of the metal sandwich panels.

[0012] Optionally, the pushing member includes a push rod slidably connected between the conveyor and the cutter, and the force-applying end of the push rod abuts against the pressure wheel, and the force-bearing end of the push rod is inclined from top to bottom in a direction away from the pressure wheel. The execution end of the cutter is provided with a trapezoidal block abutting against the force-bearing end of the push rod, which is used to move the push rod toward a direction close to the pressure wheel during the process of the cutter cutting the metal sandwich panel.

[0013] By adopting the above technical solution and the cooperation of the push rod and the trapezoidal block, the pressure wheel can move along with the operating state of the cutting machine.

[0014] Optionally, a supporting unit is provided inside the conveyor, and the supporting unit is located on the right side of the roller group close to the feeding port of the conveyor, and is used to provide support for the metal sandwich panel after the initial rolling.

[0015] Optionally, the supporting unit includes a frame rod arranged inside the conveyor, two support blocks are slidably connected to the frame rod, and the highest point of the support block is flush with the highest point of the lower roller in the roller group, and a bidirectional screw is rotatably connected inside the conveyor for driving the two support blocks to move towards each other or away from each other, and a rotation source is provided on the conveyor for driving the bidirectional screw to rotate.

[0016] Optionally, a travel switch cooperating with the rotation source is arranged in the middle of the frame rod, and the signal contact of the travel switch is flush with the highest point of the lower roller in the roller group.

[0017] By adopting the above technical solution, after the metal sandwich panel is initially rolled, the support block is used to provide support for the metal sandwich panel to prevent the front and rear edges of the metal sandwich panel from bending downward based on the rolling crease and affecting the normal progress of subsequent rolling work.

[0018] Optionally, the conveyor feeding port is vertically slidably connected to two cleaning rollers through a second elastic member, and the cleaning rollers are located between the guide spring sheet and the roller group close to the conveyor feeding port side, and are used to clean the upper and lower surfaces of the metal sandwich panel before rolling work is carried out.

[0019] By adopting the above technical solution, two cleaning rollers are used to clean the upper and lower surfaces of the metal sandwich panel during the rolling process, so as to prevent the surface quality of the metal sandwich panel from being damaged due to the influence of attachments during the rolling process.

[0020] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0023] 3. After the metal sandwich panel is rolled for the first time, the front and rear edges of the metal sandwich panel can be supported in time to prevent the front and rear edges of the metal sandwich panel from bending downward based on the rolling crease and affecting the normal development of subsequent rolling work.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application. Figure 1-Figure 6 , the technical scheme of the embodiment of the present application is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This embodiment provides a metal sandwich panel roll forming device, including a conveyor 1, a plurality of roller groups 11 arranged in pairs inside the conveyor 1, and a cutter 2 arranged at a material discharge port of the conveyor 1.

[0033] The front and rear inner walls of the feeding port of the conveyor 1 are each provided with two upper and lower symmetrical guide springs 3, a gap for the metal sandwich panel to pass through is reserved between the upper and lower guide springs 3, and the guide springs 3 are composed of a horizontal plate 31 fixedly connected to the inner wall of the conveyor 1 and a warped plate 32 abutting against the inner wall of the conveyor 1.

[0034] A pressure wheel 4 is slidably connected to each guide spring sheet 3 via a first elastic member 41 , and a pushing member 5 is provided between the conveyor 1 and the cutter 2 for moving the pressure wheel 4 away from the horizontal plate 31 while approaching the warping plate 32 .

[0035] When the metal sandwich panel enters the loading port of the conveyor 1, the edge of the unwinding end of the metal sandwich panel will enter the gap between the upper and lower guide springs 3 and abut against the warping plate 32. As the metal sandwich panel is continuously fed in, the metal sandwich panel will gradually enter between the upper and lower horizontal plates 31 along the warping plate 32 and be flattened to a certain extent, thereby reducing the probability that the unwinding end of the metal sandwich panel cannot accurately enter the rolling gap due to warping.

[0036] After the roller group 11 inside the conveyor 1 has rolled the metal sandwich panel for a certain length, the conveyor 1 stops rolling and conveying the metal sandwich panel, and the cutter 2 cuts off the part of the metal sandwich panel that has been rolled. During this process, the pusher 5 and the pressure wheel 4 cooperate to bend the warping plate 32 toward the horizontal state until the upper and lower warping plates 32 clamp the metal sandwich panel to prevent the metal sandwich panel still in the rolling gap from shaking and deviating due to the impact force generated during cutting.

[0037] Reference Figure 2 , Figure 3 and Figure 4 Each horizontal plate 31 is provided with a plurality of grooves 311, and a rolling ball 312 is rotatably connected in each groove 311 for replacing the horizontal plate 31 in contact with the metal sandwich panel, and each warping plate 32 is provided with a rubber strip 321 for replacing the horizontal plate 31 in contact with the metal sandwich panel.

[0038] During the rolling and conveying process of the metal sandwich panel, the rolling ball 312 can replace the horizontal plate 31 to contact the metal sandwich panel, thereby reducing the probability of the metal sandwich panel being scratched during the rolling and conveying process; and the rubber strip 321 can prevent the warping plate 32 from clamping the metal sandwich panel, thereby preventing the surface quality of the metal sandwich panel from being damaged.

[0039] Reference Figure 4 The depth of each groove 311 is greater than the radius of the rolling ball 312 and less than the diameter of the rolling ball 312 .

[0040] Under the premise that the rolling balls 312 replace the horizontal plates 31 to contact the metal sandwich panels, the distance between the metal sandwich panels and the horizontal plates 31 is shortened as much as possible to prevent the metal sandwich panels from being stuck in the gap between two adjacent rolling balls 312 and affecting the normal transportation of the metal sandwich panels.

[0041] Reference Figure 2 , Figure 3 and Figure 5 The push member 5 includes a push rod 51 and a trapezoidal block 52. The push rod 51 is slidably connected between the conveyor 1 and the cutter 2, and the force-applying end of the push rod 51 abuts against the pressure wheel 4, and the force-bearing end of the push rod 51 is tilted from top to bottom in a direction away from the pressure wheel 4. The trapezoidal block 52 is arranged at the execution end of the cutter 2 and abuts against the force-bearing end of the push rod 51, and is used to move the push rod 51 toward the pressure wheel 4 during the process of the cutter 2 cutting the metal sandwich panel.

[0042] When the cutter 2 is running and drives the trapezoidal block 52 to move downward, the push rod 51 will approach the pressure wheel 4 and exert pressure on it under the pressure of the trapezoidal block 52, causing the pressure wheel 4 to move away from the horizontal plate 31 and approach the warping plate 32; conversely, when the execution end of the cutter 2 is reset, the pressure wheel 4 drives the push rod 51 to reset together under the action of the elastic potential energy of the first elastic member 41, so that the pressure wheel 4 can move with the operating state of the cutter 2.

[0043] Reference Figure 1 and Figure 6 A supporting unit 6 is provided inside the conveyor 1, and the supporting unit 6 is located on the right side of the roller group 11 close to the feeding port of the conveyor 1, and is used to provide support for the metal sandwich panel after the initial rolling.

[0044] Reference Figure 1 and Figure 6 The supporting unit 6 includes a frame rod 61, two support blocks 62, a bidirectional screw 63 and a rotation source 64. The frame rod 61 is arranged inside the conveyor 1, the two support blocks 62 are slidably connected to the frame rod 61, and the highest point of the support block 62 is flush with the highest point of the lower roller in the roller group 11, the bidirectional screw 63 is rotatably connected inside the conveyor 1 and is used to drive the two support blocks 62 to move toward each other or away from each other, and the rotation source 64 is arranged on the conveyor 1 and is used to drive the bidirectional screw 63 to rotate.

[0045] Reference Figure 1 and Figure 6 A travel switch 65 cooperating with the rotation source 64 is provided in the middle of the frame rod 61 , and the signal contact of the travel switch 65 is flush with the highest point of the lower roller in the roller group 11 .

[0046] When the metal sandwich panel is initially rolled by the roller group 11 near the feeding port of the conveyor 1, the metal sandwich panel will contact the signal contact of the travel switch 65. After receiving the signal fed back by the travel switch 65, the rotation source 64 will drive the bidirectional screw 63 to rotate an appropriate number of circles according to a predetermined procedure until the two support blocks 62 are away from each other to the farthest distance based on the initial rolling crease of the metal sandwich panel, so as to prevent the front and rear edges of the metal sandwich panel from bending downward based on the rolling crease and affecting the normal development of the subsequent rolling work.

[0047] Reference Figure 1 and Figure 2 The feeding port of the conveyor 1 is vertically slidably connected to two cleaning rollers 7 through a second elastic member 71, and the cleaning rollers 7 are located between the guide spring sheet 3 and the roller group 11 close to the feeding port of the conveyor 1, and are used to clean the upper and lower surfaces of the metal sandwich panel before the rolling work is carried out.

[0048] When the rolling work is carried out, the two cleaning rollers 7 are used to clean the upper and lower surfaces of the metal sandwich panel to prevent the surface quality of the metal sandwich panel from being damaged due to the influence of attachments during the rolling process.

[0049] The implementation principle of a metal sandwich panel roll forming device in the embodiment of the present application is:

[0050] When the metal sandwich panel enters the loading port of the conveyor 1, the edge of the unwinding end of the metal sandwich panel will enter the gap between the upper and lower guide springs 3 and abut against the warping plate 32. As the metal sandwich panel is continuously fed in, the metal sandwich panel will gradually enter between the upper and lower horizontal plates 31 along the warping plate 32 and be flattened to a certain extent, thereby reducing the probability that the unwinding end of the metal sandwich panel cannot accurately enter the rolling gap due to warping.

[0051] After the roller group 11 inside the conveyor 1 has rolled the metal sandwich panel for a certain length, the conveyor 1 stops rolling and conveying the metal sandwich panel, and the cutter 2 cuts off the part of the metal sandwich panel that has been rolled. During this process, the trapezoidal block 52 will move down together with the execution end of the cutter 2 and apply pressure to the push rod 51, and the push rod 51 will approach the pressure wheel 4 and apply pressure to it, causing the pressure wheel 4 to move away from the horizontal plate 31 and approach the warping plate 32, so that the warping plate 32 is bent toward the horizontal state, until the upper and lower warping plates 32 clamp the metal sandwich panel to prevent the metal sandwich panel still in the rolling gap from shaking and deviating due to the impact force generated during cutting.

[0052] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0053] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
