Cutting device of a tile press

Abstract

The application relates to a cutting device of a tile pressing machine, which comprises a rack, an upper cutter sliding up and down on the rack, a driving element one arranged on the rack and used for driving the upper cutter to slide up and down, a fixing block arranged on the rack and located below the upper cutter, a cutting groove arranged on the fixing block and used for clamping the upper cutter, and a supporting surface arranged on the fixing block and located on the two sides of the cutting groove. The supporting surface is arranged in close contact with the surface of a metal panel. When the metal panel moves to the supporting surface of the fixing block and the cutting position of the metal panel is aligned with the cutting groove, the driving element one drives the upper cutter to move downward and clamp into the cutting groove. When the metal panel is sheared, the supporting surface is in close contact with the two sides of the cutting position of the metal panel, so that the shearing surface of the metal panel is prevented from being bent and deformed, the shearing surface of the metal panel is more flat, and the influence on the composite strength of the metal panel and a core material after the metal panel is compounded with the core material is reduced.

Description

Technical Field

[0001] This application relates to the field of roll forming machines, and more particularly to a cutting device for a roll forming machine. Background Technology

[0002] With the acceleration of urbanization and the increasing demand for flexible living environments, mobile homes, due to their rapid construction, easy transportation and reuse, are gradually becoming an important choice for temporary housing, construction site camps and emergency resettlement.

[0003] The main structure of mobile homes is mostly built with lightweight, high-strength sandwich panels. These panels are usually composed of two layers of metal panels (such as color steel plates or galvanized plates) and an insulation core material (such as polystyrene, polyurethane, or rock wool) in the middle. They have the functions of heat insulation, waterproofing, fireproofing, and structural support, and are the core material for achieving modular and rapid assembly of mobile homes.

[0004] The processing and forming of sandwich panels rely on a roll forming machine. The roll forming machine uses continuous roller pressing to press metal coils into panels with specific cross-sectional shapes (such as corrugated, trapezoidal, right-angled, etc.). Then, the panels are cut to a fixed length according to the design dimensions and then combined with the core material to form sandwich panels.

[0005] Currently, most roll forming machines use staggered upper and lower cutting blades to shear metal panels. This means that the blades of the upper and lower cutting blades are not on the same vertical plane and have a certain lateral offset. When the upper cutting blade descends, the blade of the upper cutting blade causes the metal panel to break at the contact point through the lateral offset shearing force. With this shearing method, the sheared surface of the metal panel is prone to bending or deformation, which will cause gaps at the bonding area between the metal panel and the core material when they are subsequently laminated together, reducing the composite strength. This method needs to be improved. Summary of the Invention

[0006] To address the issue that staggered shearing can cause bending or deformation of the sheared surface of the metal panel, leading to gaps at the bonding point between the metal panel and the core material during subsequent lamination with the core material and reducing the composite strength, this application provides a cutting device for a tile press machine.

[0007] The cutting device for a tile press machine provided in this application adopts the following technical solution:

[0008] A cutting device for a tile press machine includes a frame, an upper cutter that slides and moves vertically on the frame, a drive unit for driving the upper cutter to move up and down on the frame, a fixing block on the frame located below the upper cutter, a cutting groove for the upper cutter to engage on the fixing block, and a support surface on the fixing block located on both sides of the cutting groove, the support surface being fitted to the surface of a metal panel.

[0009] By adopting the above technical solution, when the metal panel moves to the support surface of the fixed block and the cutting area of ​​the metal panel is aligned with the cutting groove, the drive unit drives the upper cutter to move down and get into the cutting groove. During the cutting process, the support surface fits tightly against both sides of the cutting area of ​​the metal panel, thereby suppressing the bending and deformation of the cutting surface of the metal panel, making the cutting surface of the metal panel flatter and reducing the impact on the composite strength after the metal panel and the core material are combined.

[0010] Optionally, the frame has a through hole, the upper cutter and the fixing block are located in the through hole, a feeding roller is rotatably connected to the frame, the feeding roller is located outside the through hole and between the support surface and the bottom wall of the through hole, and the rotation axis of the feeding roller is horizontally arranged. The feeding roller has several elastic strips circumferentially arranged, and the frame is provided with a second driving member for driving the feeding roller to rotate.

[0011] By adopting the above technical solution, after the metal panel is cut, the metal panel falls onto the first feeding roller. The second driving component drives the first feeding roller to rotate. The first feeding roller pushes the metal panel away from the through hole and falls down through the frictional resistance between the elastic strip and the metal panel, which reduces the situation of the metal panel hitting and scratching the bottom wall of the through hole, and helps to improve the appearance quality of the metal panel.

[0012] Optionally, the frame is provided with a second feeding roller, which is located on the side of the first feeding roller close to the upper cutter, and the upper end of the second feeding roller is higher than the upper end of the first feeding roller.

[0013] By adopting the above technical solution, when the metal panel is being sheared, the conveying of the metal panel will be paused. The second feeding roller abuts against the metal panel before the first feeding roller, which can support the metal panel during the shearing process, keep it stable, and suppress the tendency of the metal panel to tilt. This can further suppress the deformation of the sheared surface of the metal panel. Compared with the support of the first feeding roller, the wear of the elastic strip caused by the continuous rotation of the first feeding roller can be reduced.

[0014] Optionally, the distance between the second feeding roller and the upper cutting blade is less than half the length of the metal panel.

[0015] By adopting the above technical solution, the center of gravity of the metal panel after shearing is shifted to the side of the lower roller two that is closer to the lower roller one, which makes it easier for the metal panel to fall onto the lower roller one after shearing.

[0016] Optionally, the second feeding roller is rotatably connected to the frame, and the rotation axis of the second feeding roller is parallel to the rotation axis of the first feeding roller.

[0017] By adopting the above technical solution, the wear between the second feeding roller and the metal panel is reduced during the conveying process of the metal panel by the rotation of the second feeding roller.

[0018] Optionally, the feeding roller includes a roller body rotatably connected to the frame, a connecting block threadedly connected to the roller body, an abutment block rotatably connected to the connecting block, and several mounting blocks. The driving member two drives the roller body to rotate. The elastic strip is provided on the mounting block. The roller body has several mounting grooves circumferentially. The mounting grooves penetrate the roller body in the direction close to the connecting block. The mounting grooves are for the mounting blocks to be engaged. The mounting block has a positioning groove. The frame has a through hole. The through hole is located on the side of the roller body away from the driving member two. The connecting block passes through the through hole. The abutment block is located on the side of the through hole close to the roller body. The rotation axis of the abutment block is parallel to the rotation axis of the roller body. The abutment block has a positioning block. The positioning groove is for the positioning block to be engaged.

[0019] By adopting the above technical solution, when the elastic strip is worn or damaged to the point of being unusable, the connecting block is twisted to move the abutment block away from the roller body until the positioning block disengages from the positioning groove. The damaged elastic strip and its mounting block are then removed and replaced. The mounting block with the intact elastic strip is inserted into the mounting groove, and then the connecting block is twisted to make the abutment block abut against the roller body and the positioning block is inserted into the positioning groove, thus positioning the mounting block. There is no need to replace the entire feeding roller, which helps to extend the service life of the feeding roller, reduce material loss, and lower production costs.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. When the metal panel moves to the support surface of the fixed block and the cutting area of ​​the metal panel is aligned with the cutting groove, the drive unit drives the upper cutter to move down and get into the cutting groove. During the cutting process, the support surface fits tightly against both sides of the metal panel to be cut, thereby suppressing the bending and deformation of the cutting surface of the metal panel, making the cutting surface of the metal panel flatter and reducing the impact on the composite strength after the metal panel and the core material are combined.

[0022] 2. By setting up the first feeding roller, the occurrence of metal panels falling onto the bottom wall of the through hole and being bumped and scratched is reduced, which helps to improve the appearance quality of the metal panels;

[0023] 3. By setting up a second feeding roller, the conveying of the metal panel will pause when the metal panel is being sheared. The second feeding roller will abut against the metal panel before the first feeding roller, supporting the metal panel during the shearing process, maintaining stability, and suppressing the tendency of the metal panel to tilt. This further suppresses the deformation of the sheared surface of the metal panel. Compared with the support provided by the first feeding roller, this reduces the wear of the elastic strip caused by the continuous rotation of the first feeding roller. Attached Figure Description

[0029] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0030] Example 1

[0031] This application discloses a cutting device for a tile pressing machine. See also... Figure 1The cutting device of the tile press machine includes a frame 1, on which a through hole 11 is opened, the through hole 11 horizontally penetrating the frame 1. An upper cutter 2 is slidably moved up and down on the frame 1, the upper cutter 2 is located in the through hole 11. A drive component 3 is also fixed on the frame 1, the drive component 3 is located above the frame 1. In this embodiment, there are two drive components 3, the two drive components 3 are arranged at intervals along the length direction of the upper cutter 2. The piston rod of each drive component 3 passes through the frame 1 and is fixedly connected to the upper cutter 2. The drive component 3 drives the upper cutter 2 to move up and down. In this embodiment, the drive component 3 is a hydraulic cylinder.

[0032] See Figure 1 A fixing block 4 is fixed on the frame 1. The fixing block 4 is located in the through hole 11 and below the upper cutter 2. The upper end face of the fixing block 4 has a cutting groove 41 for the upper cutter 2 to be inserted. The cutting groove 41 passes through the fixing block 4 along the length direction of the upper cutter 2. The upper end face of the fixing block 4 is machined to form a support surface 5. The support surface 5 is located on both sides of the cutting groove 41 and is set to fit the surface of the metal panel.

[0033] The implementation principle of Embodiment 1 of this application is as follows:

[0034] When the metal panel moves onto the support surface 5 of the fixing block 4, and the area to be cut on the metal panel is aligned with the groove 41, the drive component 3 drives the upper cutter 2 to move down and engage in the groove 41. During shearing, the support surface 5 adheres tightly to both sides of the area to be cut on the metal panel, thereby suppressing the bending and deformation of the sheared surface of the metal panel, making the sheared surface of the metal panel flatter and reducing the impact on the composite strength of the subsequent metal panel and core material.

[0035] Example 2

[0036] See Figures 2-4 The difference between this embodiment and embodiment 1 is that a feeding roller 6 is rotatably connected to the frame 1. The feeding roller 6 is located outside the through hole 11 and between the support surface 5 and the bottom wall of the through hole 11. The feeding roller 6 includes a roller body 61, a connecting block 62, an abutment block 63 and several mounting blocks 64. The roller body 61 is rotatably connected to the frame 1, and the rotation axis of the roller body 61 is horizontally set and parallel to the length direction of the upper cutter 2. A second driving component 7 is fixed on the frame 1. The second driving component 7 is located on one side of the roller body 61, and the output shaft of the second driving component 7 is coaxially fixed with the roller body 61. The second driving component 7 drives the roller body 61 to rotate. In this embodiment, the second driving component 7 is a motor.

[0037] See Figures 2-4The outer side wall of the roller body 61 is provided with a plurality of mounting grooves 611 evenly spaced circumferentially. Each mounting groove 611 penetrates the roller body 61 in a direction away from the driving component 7. The number and position of the plurality of mounting blocks 64 correspond one-to-one with the number and position of the mounting grooves 611. The mounting grooves 611 are for the mounting blocks 64 to be inserted. Each mounting block 64 is provided with a positioning groove 641 on its outer side wall. When the mounting block 64 is inserted into the mounting groove 611, the positioning groove 641 is located on the side of the mounting block 64 away from the driving component 7. Each mounting block 64 is fixed with an elastic strip 8. When the mounting block 64 is inserted into the mounting groove 611, the elastic strip 8 is located on the side of the mounting block 64 away from the roller body 61. In this embodiment, the material of the elastic strip 8 is rubber.

[0038] See Figures 2-4 A threaded groove 612 is provided on the side of the roller body 61 away from the drive component 7. The threaded groove 612 is used for threaded connection of the connecting block 62. A through hole 12 is provided on the frame 1. The through hole 12 is located on the side of the roller body 61 away from the drive component 7. The connecting block 62 passes through the through hole 12 and abuts against the inner wall of the through hole 12, thereby supporting the feed roller 6, reducing the force on the output shaft of the drive component 7, and helping to extend the service life of the drive component 7.

[0039] See Figures 2-4 The abutment block 63 is located on the side of the perforation 12 near the roller body 61 and is sleeved on the outside of the connecting block 62. The abutment block 63 and the connecting block 62 are rotatably connected. The rotation axis of the abutment block 63 and the connecting block 62 is parallel to the rotation axis of the roller body 61. Several positioning blocks 9 are fixed on the abutment block 63. The number and position of the positioning blocks 9 correspond one-to-one with the number and position of the positioning grooves 641. The positioning grooves 641 are for the positioning blocks 9 to be inserted.

[0040] In actual use, when the elastic strip 8 is worn or damaged to the point of being unusable, twist the connecting block 62 to move the abutment block 63 away from the roller body 61 until the positioning block 9 disengages from the positioning groove 641. Remove the damaged elastic strip 8 and its mounting block 64 for replacement. Insert the intact mounting block 64 of the elastic strip 8 into the mounting groove 611. Then twist the connecting block 62 to make the abutment block 63 abut against the roller body 61 and the positioning block 9 into the positioning groove 641, thus positioning the mounting block 64.

[0041] See Figures 2-4 The frame 1 is also rotatably connected to a second feeding roller 10. The second feeding roller 10 is located on the side of the roller body 61 near the upper cutter 2, and the upper end of the second feeding roller 10 is higher than the upper end of the first feeding roller 6. The rotation axis of the second feeding roller 10 is parallel to the rotation axis of the roller body 61. The distance between the second feeding roller 10 and the upper cutter 2 is less than half the length of the metal panel.

[0042] The implementation principle of Embodiment 2 of this application is as follows:

[0043] When the metal panel is being sheared, the feeding roller 10 supports the metal panel by abutting against it, keeping it stable and suppressing the tendency of the metal panel to tilt. This suppresses the deformation of the sheared surface of the metal panel. After shearing, the cut metal panel falls onto the roller 61 under the action of gravity. The driving component 7 drives the roller 61 to rotate. The roller 61 pushes the metal panel away from the through hole 11 and then falls down through the frictional resistance between the elastic strip 8 and the metal panel. This reduces the chance of the metal panel hitting and scratching the bottom wall of the through hole 11, which helps to improve the appearance quality of the metal panel.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
