Description

Technical Field

[0001] This utility model relates to a metal sheet forming equipment, and more particularly to a corner forming machine. Background Technology

[0002] After the rock wool board panels are cut, their ends usually need to be bent to form retaining edges. This process is typically done using a corner forming machine. Traditional corner forming machines usually have their shearing blades simply fixed to the blade holder with bolts. The mating surfaces of the bolts and the blade holder are arranged perpendicularly. After each disassembly and reassembly, the relative position between the shearing blade and the blade holder will inevitably shift. That is, it is difficult to guarantee that the relative position between the shearing blade and the blade holder will remain unchanged after each disassembly and reassembly. Therefore, after each disassembly and reassembly of the shearing blade, readjustment is required, which is inconvenient to use.

[0003] In view of this, the applicant has conducted in-depth research on the structure of the corner forming machine, which led to this case. Utility Model Content

[0004] The purpose of this invention is to provide an easy-to-use corner forming machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A corner forming machine includes a frame, on which a lower pressing module and an upper pressing module are vertically slidably connected. The lower pressing module is located directly above the upper pressing module. The frame also includes a lower pressing cylinder for driving the lower pressing module to slide and an upper pressing cylinder for driving the upper pressing module to slide. The lower pressing module includes a lifting plate slidably connected to the frame, an upper blade mounting seat fixedly connected to the lower end of the lifting plate, and a shearing and bending upper blade and an upper blade pressing block respectively mounted on the upper blade mounting seat. A transverse groove is formed at the lower end of the upper blade mounting seat, the width of which is... A groove wall is formed on one side and a side opening is formed on the other side. The upper blade pressing block abuts against the side wall of the upper blade mounting base and covers the side opening. The upper blade pressing block, the groove wall, and the bottom surface of the transverse groove together form a dovetail groove. The shearing upper blade is provided with a dovetail tenon inserted into the dovetail groove. A first bolt is inserted into the upper blade pressing block and is simultaneously spirally connected to the upper blade mounting base. The nut of the first bolt abuts against the upper blade pressing block, and the screw of the first bolt is arranged to gradually tilt upward from one end relatively far away from the upper blade mounting base to the other end.

[0007] As an improvement of this utility model, a second bolt is also inserted through the upper blade pressure block and simultaneously spirally connected to the upper blade mounting base. The nut of the second bolt abuts against the upper blade pressure block, and the screw of the second bolt is arranged horizontally.

[0008] As an improvement of this utility model, there are multiple first bolts and multiple second bolts. Each first bolt and each second bolt is arranged alternately in a straight line along the length direction of the upper blade pressure block, and each first bolt and each second bolt is staggered with each other.

[0009] As an improvement of this utility model, the upper knife mounting seat has a process groove at the position between the bottom surface of the horizontal groove and the groove wall.

[0010] As an improvement of this utility model, the frame is also provided with a synchronization mechanism for controlling the synchronous operation of the pressing module and the pressing module.

[0011] As an improvement of this utility model, the upper pressure cylinder and / or the lower pressure cylinder includes a cylinder body and a piston located in the inner cavity of the cylinder body. The piston divides the inner cavity of the cylinder body into a relatively independent first chamber and a second chamber. Both the first chamber and the second chamber have an oil inlet hole and an oil return hole on their side walls. A pressure control valve is installed on the oil return hole of the second chamber.

[0012] By adopting the above technical solution, this utility model has the following beneficial effects:

[0013] 1. A dovetail groove is formed by setting a transverse groove and an upper blade pressure block. The first bolt, which is arranged at an angle, ensures that the upper blade pressure block can press the dovetail tenon tightly onto the bottom surface of the dovetail groove, eliminating the assembly gap between the dovetail groove and the dovetail tenon. In this way, the bottom surface of the dovetail groove and the contact surface of the upper blade pressure block can be used to position the shearing blade. This ensures that the position of the shearing blade does not shift or the shift is negligible after each disassembly and assembly of the shearing blade, saving debugging time during use and making it more convenient to use.

[0014] 2. By setting a pressure control valve, the jerking phenomenon during bending can be avoided, thereby preventing wrinkles from forming on the metal sheet. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The terms "first," "second," etc., used in this invention are used to distinguish different objects, rather than to describe a specific order.

[0027] like Figures 1-3 As shown, this embodiment provides a corner forming machine, including a frame 10. A lower pressing module 20 and an upper pressing module 30 are vertically slidably connected on the frame 10. The lower pressing module 20 is located directly above the upper pressing module 30. Specifically, the two are slidably connected on the same set of slide rods. The specific sliding connection structure is the same as that of a conventional corner forming machine, which is not the focus of this embodiment and will not be described in detail here.

[0028] The frame 10 is also equipped with a lowering cylinder 40 for driving the lowering module 20 to slide and an uppering cylinder 50 for driving the uppering module 30 to slide. Similar to conventional cylinders, in this embodiment, both the uppering cylinder 40 and the lowering cylinder 50 include a cylinder body and a piston located in the inner cavity of the cylinder body. The piston divides the inner cavity of the cylinder body into a relatively independent first chamber and a second chamber. Both the first chamber and the second chamber have oil inlet holes and oil return holes on their side walls for connection to the hydraulic system of the angle forming machine. Of course, the hydraulic system and its specific connection structure with each oil inlet hole and oil return hole are the same as in conventional angle forming machines, and will not be described in detail here. Unlike conventional angle forming machines, in this embodiment, a pressure control valve is installed on the oil return hole of each second chamber. The pressure control valve can be directly installed on the oil return hole, or it can be indirectly installed on the oil return hole via a pipe connected to it. It should be noted that a pressure control valve may also be installed only on the upper pressure cylinder 40 or the lower pressure cylinder 50.

[0029] Taking the pressing module 20 as an example, when the pressing module 20 needs to perform a pressing action, hydraulic oil flows into the first chamber through the corresponding oil inlet to increase the pressure. Before the hydraulic pressure in the second chamber reaches the pressure value preset by the pressure control valve, the hydraulic oil in the second chamber cannot flow out due to the presence of the pressure control valve, so the piston will not move. After the hydraulic pressure in the second chamber reaches the pressure value preset by the pressure control valve, the hydraulic oil in the second chamber flows out through the pressure control valve, the piston moves and drives the pressing module 20 to perform the pressing action, ensuring that the pressing action has sufficient pressure, avoiding the pressing module 20 from experiencing a jerking phenomenon due to excessive external resistance during the execution of the action, and thus avoiding wrinkles on the metal plate.

[0030] Preferably, in order to ensure that the pressing module 20 and the pressing module 30 operate synchronously, in this embodiment, the frame 10 is also provided with a synchronization mechanism 60 for controlling the synchronous operation of the pressing module 20 and the pressing module 30. The synchronization mechanism 60 is a conventional mechanism, such as a gear synchronization mechanism or a chain synchronization mechanism. Of course, the synchronous operation of the pressing module 20 and the pressing module 30 can also be ensured by controlling the pressing cylinder 40 and the pressing cylinder 50 through the controller.

[0031] The pressing module 20 includes a lifting plate 21 slidably connected to the frame 10, an upper blade mounting base 22 fixedly connected to the lower end of the lifting plate 21, and a shearing and bending upper blade 23 and an upper blade pressing block 24 respectively mounted on the upper blade mounting base 22. The lower end of the upper blade mounting base 22 has a horizontal groove, the length direction of which is the same as the length direction of the upper blade mounting base 22. Both ends of the horizontal groove in the length direction pass through the upper blade mounting base 22. One side of the horizontal groove in the width direction forms a groove wall, and the other side passes through the upper blade mounting base 22 and forms a side opening. The groove wall is arranged to gradually slope away from the side opening from bottom to top. The upper blade pressing block 24 abuts against the side wall of the upper blade mounting base 22 and covers the side opening. The upper blade pressing block 24 has a protrusion that penetrates the horizontal groove. The protrusion has an inclined surface that corresponds to the groove wall. The inclined surface and the groove wall are arranged in an inverted V-shape. In this way, the upper blade pressing block 24, the groove wall, and the bottom surface of the horizontal groove can be together to form a dovetail groove. The upper shearing blade 23 is provided with a dovetail tenon 25 inserted into the dovetail groove, and the upper blade pressure block 24 is provided with a first bolt 26 that is screwed onto the upper blade mounting base 22. Specifically, the nut of the first bolt 26 abuts against the side of the upper blade pressure block 24 away from the upper blade mounting base 22. The screw of the first bolt 26 is arranged to gradually slope upward from the end relatively away from the upper blade mounting base to the other end, preferably perpendicular to the aforementioned inclined surface. In this way, when the first bolt 26 is tightened, the dovetail tenon 26 will be pressed against the bottom surface of the transverse groove by the upper blade pressure block 24, eliminating assembly gaps and ensuring that the relative position of the upper shearing blade 23 and the upper blade mounting base 22 in the vertical direction does not shift or the shift is so small as to be negligible after each disassembly and assembly of the upper shearing blade 23, saving adjustment time during use and making it more convenient to use.

[0032] Preferably, a second bolt 27 is also inserted into the upper blade pressure block 24 and simultaneously screwed onto the upper blade mounting base 22. The nut of the second bolt 27 abuts against the side of the upper blade pressure block 24 away from the upper blade mounting base 22, and the thread of the second bolt 27 is arranged horizontally; this helps to prevent the cement pipe pressure block 24 from loosening. In this embodiment, there are multiple first bolts 26 and second bolts 27. Each first bolt 26 and each second bolt 27 is arranged alternately in a straight line along the length direction of the upper blade pressure block 24, and each first bolt 26 and each second bolt 27 is staggered with each other.

[0033] In addition, the upper knife mounting base 22 has a process groove 28 at the position between the bottom surface of the horizontal groove and the groove wall to provide clearance space and ensure that the dovetail tenon 25 can be pressed tightly against the bottom surface of the horizontal groove.

[0034] The structure of the upper pressure module 30 is the same as that of a conventional corner forming machine, and it is not the focus of this embodiment, so it will not be described in detail here.

[0035] The present invention has been described in detail above with reference to the accompanying drawings. However, the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various modifications to the present invention based on the prior art, and these modifications all fall within the protection scope of the present invention.
