Description

Technical Field

[0001] This utility model relates to the technical field of metal insulation board processing equipment, and in particular to a bending device for metal insulation boards. Background Technology

[0002] Metal insulation boards have excellent thermal insulation properties and high strength, and are widely used in construction, industry and other fields. During the processing of metal insulation boards, they often need to be bent to meet different usage requirements.

[0003] Chinese utility model patent CN209773277U discloses a bending device for metal insulation boards, which can effectively perform bending operations. Through the setting of heating and moving rollers, it can reduce metal plate breakage during processing, lower the scrap rate, and reduce costs. Simultaneously, the fixed rollers facilitate fixing and handling, simplifying operation and increasing efficiency. Regarding the aforementioned related technology, the inventors believe that the following defects exist: At the moment of bending, due to uneven force application in the bending mechanism, the slight traction force generated when the moving bending block bends the plate will cause the unbent portion of the plate in front of the bending device to shift. This not only leads to slight differences in plate dimensions and deviations of the bending angle from the preset value, but also, due to the change in the force point, further amplifies the shift angle in subsequent processing, seriously affecting bending accuracy. Utility Model Content

[0004] To solve the above problems, this utility model provides a bending device for metal insulation boards.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a bending device for metal insulation boards, including a machine cover, a hydraulic rod installed on the surface of the machine cover, the piston end of the hydraulic rod extending into the machine cover and connected to a mounting plate disposed inside the machine cover, a pressure plate head installed on one side of the bottom surface of the mounting plate, an L-shaped pressure seat fixedly installed on the bottom surface inside the machine cover, a C-shaped pressure frame fixedly installed on the bottom surface of the mounting plate and on one side of the pressure plate head, and a plurality of auxiliary pressure rods installed at equal intervals inside the C-shaped pressure frame.

[0006] By adopting the above technical solution, the C-shaped pressure frame is fixed to the bottom surface of the mounting plate and one side of the pressure plate head. Its "C-shaped" frame structure can cover one side of the plate surface to be bent before bending. When pressing down, the C-shaped pressure frame contacts the plate before the pressure plate head, and works with the auxiliary pressure rod, telescopic rod, extrusion plate, and spring to distribute the local pressure of the pressure plate head through large-area pre-pressing, avoiding the plate from shifting due to instantaneous concentrated force. The spatial layout limits the sliding range of the plate, and the equidistant layout makes the pressure distribution on the plate contact surface more uniform, avoiding plate deformation and scratches caused by local stress concentration. It is especially suitable for materials with high surface quality requirements, such as metal insulation boards.

[0007] Furthermore, the bottom surfaces of the C-shaped pressure frame and the auxiliary pressure rod are both fixedly connected to a telescopic rod, the other end of the telescopic rod is fixed to a pressing plate, and a spring is sleeved on the outer surface of the telescopic rod.

[0008] By adopting the above technical solution, when the extrusion plate contacts the plate through the telescopic rod and the spring three, the elastic force of the spring three will evenly distribute the pressure to the surface of the plate, avoiding local indentations or scratches caused by uneven contact in traditional rigid pressure plates.

[0009] Furthermore, one end of the L-shaped pressure seat is inclined upwards, and a pulley is installed on the inclined surface.

[0010] By adopting the above technical solution, when the pressure plate head is pressed down, the plate first slides along the inclined surface and gradually bends. Compared with bending directly on the vertical surface, this design makes the bending force distribution more uniform and reduces the risk of plate cracking caused by stress concentration. The pulley is installed at the top of the inclined surface, which transforms the traditional sliding friction into rolling friction. During the bending process of the plate, the pulley rolls with the plate, avoiding scratches and abrasions caused by sliding friction. It is especially suitable for metal insulation boards with coatings or films on the surface.

[0011] Furthermore, a fixing rod is fixedly installed on one side of the mounting plate, and a wedge is fixedly installed at one end of the fixing rod through the groove on the surface of the machine cover. A connecting square rod is slidably connected to the surface of the machine cover, and a connecting plate is fixed at one end of the connecting square rod extending to the surface of the machine cover. A wedge block slide is slidably connected to the surface of the connecting plate, and the wedge block is slidably connected in the wedge block slide. One end of the connecting square rod extending into the machine cover is connected to a limiting clamp plate set inside the machine cover.

[0012] By adopting the above technical solution, when the mounting plate moves downward under the drive of the hydraulic rod, the fixing rod moves accordingly, causing the wedge to move downward. The wedge and the inclined surface of the wedge slide cooperate to convert the vertical movement into the horizontal movement of the connecting square rod, thereby pushing the limiting clamping plate to move towards the plate. This can quickly clamp the side of the plate before bending, prevent the plate from shifting to one side, ensure accurate bending position, and reduce dimensional errors.

[0013] Furthermore, a spring is fitted onto the surface of the connecting rod, with one end of the spring abutting against one side of the connecting plate and the other end abutting against the surface of the machine cover.

[0014] By adopting the above technical solution, when the bending process is completed and the mounting plate rises and resets under the action of the hydraulic rod, the elastic potential energy of the first spring is released, which pushes the connecting plate, connecting square rod and limiting clamp plate to automatically return to the initial position without the need for an additional reset drive device.

[0015] Furthermore, the surface of the limiting clamp is slidably connected with multiple T-shaped rods, and the same end of the multiple T-shaped rods is connected to an anti-deviation plate. Springs are sleeved on the outer surfaces of the multiple T-shaped rods and between the limiting clamp and the anti-deviation plate.

[0016] By adopting the above technical solution, at the moment of bending, the lateral displacement caused by uneven force on the plate will exert an impact force on the anti-deviation plate. At this time, the spring absorbs energy through compression deformation, converts the impact force into elastic restoring force, and acts in the opposite direction on the plate, thereby offsetting the lateral force in real time and preventing the plate from deviating.

[0017] Furthermore, the telescopic rod is composed of two rods with different diameters, with the smaller diameter rod slidably connected inside the larger diameter rod.

[0018] By adopting the above technical solution, the guiding effect of the C-shaped pressure frame and the auxiliary pressure rod pressing vertically is ensured, so that the extrusion plate is evenly attached to the surface of the plate, thereby improving the pressing accuracy and consistency.

[0019] Furthermore, the extrusion plate and the anti-deviation plate are both provided with anti-slip pads on the side that contacts the plate.

[0020] By adopting the above technical solutions, the anti-slip mat increases the friction of the contact surface, offsets the external force on the sheet material during bending, ensures that the sheet material is stable and does not slip during processing, improves positioning accuracy, and the elastic material of the anti-slip mat can buffer rigid compression, avoiding indentations, scratches or coating damage caused by direct metal contact.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. In this application, the large-area pre-compression of the C-shaped pressure frame and auxiliary pressure rod, and the lateral clamping of the limiting clamp and anti-deviation plate, effectively prevent the plate from shifting during the bending process, ensure accurate bending position, greatly reduce dimensional errors, and ensure the dimensional consistency of metal insulation boards in mass production.

[0023] 2. In this application, the anti-slip pads on the contact side of the extrusion plate and anti-deviation plate with the board, together with the elastic buffer of spring three and spring two, avoid the indentation and scratches caused by rigid extrusion on the surface of the board; 3. The pulley on the inclined surface of the L-shaped pressure seat converts sliding friction into rolling friction, preventing damage to the coating or film on the surface of the board, and effectively improving the surface quality and product quality of the metal insulation board.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] like Figure 1-7 As shown in the figure, this application discloses a bending device for metal insulation boards, including a machine cover 1. A hydraulic rod 2 is installed on the surface of the machine cover 1. The piston end of the hydraulic rod 2 extends into the machine cover 1 and is connected to a mounting plate 3 disposed inside the machine cover 1. A pressure head 4 is installed on one side of the bottom surface of the mounting plate 3. An L-shaped pressure seat 5 is fixedly installed on the bottom surface inside the machine cover 1. A C-shaped pressure frame 17 is fixedly installed on the bottom surface of the mounting plate 3 and on one side of the pressure head 4. A plurality of auxiliary pressure rods 18 are installed at equal intervals inside the C-shaped pressure frame 17.

[0033] Specifically, the bottom surfaces of the C-shaped pressure frame 17 and the auxiliary pressure rod 18 are both fixedly connected to a telescopic rod 19, and the other end of the telescopic rod 19 is fixed to a pressing plate 20. A spring 21 is sleeved on the outer surface of the telescopic rod 19.

[0034] Specifically, one end of the L-shaped pressure seat 5 is inclined upwards, and a pulley 6 is installed on the inclined surface.

[0035] Specifically, a fixing rod 7 is fixedly installed on one side of the mounting plate 3. A wedge block 8 is fixedly installed at one end of the fixing rod 7 through the groove on the surface of the machine cover 1. A connecting square rod 11 is slidably connected to the surface of the machine cover 1. A connecting plate 10 is fixed at one end of the connecting square rod 11 extending to the surface of the machine cover 1. A wedge block slide 9 is slidably connected to the surface of the connecting plate 10. The wedge block 8 is slidably connected in the wedge block slide 9. One end of the connecting square rod 11 extending into the machine cover 1 is connected to the limiting clamp 13 set in the machine cover 1.

[0036] Specifically, a spring 12 is fitted on the surface of the connecting rod 11. One end of the spring 12 abuts against one side of the connecting plate 10, and the other end of the spring 12 abuts against the surface of the cover 1.

[0037] Specifically, multiple T-shaped rods 14 are slidably connected to the surface of the limiting clamp 13, and the same end of the multiple T-shaped rods 14 is connected to the anti-deviation plate 16. Springs 15 are sleeved on the outer surface of the multiple T-shaped rods 14 and located between the limiting clamp 13 and the anti-deviation plate 16.

[0038] Specifically, the telescopic rod 19 consists of two rods with different diameters, with the smaller diameter rod slidingly connected inside the larger diameter rod.

[0039] Specifically, anti-slip pads are provided on the side of the extrusion plate 20 and the anti-deviation plate 16 that are in contact with the sheet material.

[0040] The working principle of the bending device for metal insulation board in this embodiment is as follows: the metal insulation board is placed on the surface of the L-shaped pressure seat 5, one end of the board rests on the pulley 6 on the inclined surface of the L-shaped pressure seat 5, and the other end extends to the corresponding position inside the machine cover 1. At this time, the bending line and the matching position of the pressure plate head 4 and the L-shaped pressure seat 5 can be initially aligned by adjusting the placement of the board.

[0041] The piston end of the control hydraulic rod 2 extends, driving the mounting plate 3 to move downwards. The pressure plate head 4 and C-shaped pressure frame 17 on the bottom surface of the mounting plate 3 move downwards simultaneously.

[0042] When the C-shaped pressure frame 17 moves down, the extrusion plate 20 connected to its bottom telescopic rod 19 first contacts the surface of the board, and the spring 3 21 is compressed. The elastic force is used to initially press the board firmly onto the L-shaped pressure seat 5 to avoid slipping during bending.

[0043] At the same time, the fixing rod 7 on the side of the mounting plate 3 moves down, the wedge block 8 at the end of the rod presses the wedge block slide 9 on the surface of the machine cover 1, pushes the connecting square rod 11 to move horizontally, and the spring 12 is compressed and stored. The connecting square rod 11 drives the limiting clamping plate 13 to approach the plate. The limiting clamping plate 13, through the anti-deviation plate 16 connected by the T-shaped rod 14, cooperates with the elastic force of the spring 15 to clamp the plate from the side, counteract the lateral traction force during bending, and prevent the plate from shifting.

[0044] The pressure plate head 4 continues to press down, cooperating with the L-shaped pressure seat 5 to apply bending force to the metal insulation board. Utilizing the mechanical structure of the two, the board is bent to the target angle, completing the bending operation.

[0045] After bending, the piston end of hydraulic rod 2 retracts, mounting plate 3 moves upward, and all components move upward and reset. Extrusion plate 20 separates from the sheet metal due to the rebound of spring 3 21, wedge block 8 disengages from wedge block slide 9, connecting square rod 11 returns to its original position under the elastic force of spring 12, limiting clamp 13 and anti-deviation plate 16 loosen the sheet metal, and the operator or robotic arm removes the bent sheet metal, completing one work cycle.
