DETAILED DESCRIPTION
[0024] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.
[0025] like Figure 1-4 As shown, the technical solution adopted by the utility model is specifically as follows: a clamping device for a metal plate bending machine comprises a bottom plate 1, a first through groove 2 and a first slide groove 3 are arranged on the bottom plate 1, a plurality of first rollers 4 are arranged inside the first through groove 2, a fixed plate 5 is arranged inside the first slide groove 3, a sliding plate is sleeved on the fixed plate 5, a first connecting plate 7 is arranged on the sliding plate 6, a plurality of elastic components are arranged on the first connecting plate 7, a side limit plate 8 is arranged on the plurality of elastic components, and a second roller 9 is arranged on the side limit plate 8;
[0026] Two groups of driving components are arranged on the base plate 1, each driving component is arranged with a second connecting plate 10, a third connecting plate 11 is arranged on the side where the two second connecting plates 10 are close to each other, a second through groove is opened on the third connecting plate 11, a plurality of third rollers 12 are arranged inside the second through groove, and a fourth connecting plate 13 is hingedly arranged at the bottom of the two second connecting plates 10, and one end of the fourth connecting plate 13 away from the second connecting plate 10 is hinged to the sliding plate 6.
[0027] Its working principle is as follows: first, place the required metal plate on the first roller 4 on the bottom plate 1, and then provide power through the driving component to move the two second connecting plates 10 downward. When the second connecting plate 10 moves downward, it drives the third connecting plate 11 to make the third roller 12 inside the second through groove move downward, thereby clamping the metal plate. The metal plate is limited and fixed by the first roller 4 and the third roller 12, which can not only adapt to metal plates of different thicknesses, but also move when pressing to prevent shaking during transportation. At the same time, when the two second connecting plates 10 move downward, the second connecting plate 10 drives the fourth connecting plate 13 to move the sliding plate 6 in the fixed plate 5 inside the slide groove, thereby driving the first connecting plate 7 to make the elastic component drive the side limiting plate 8 to press the two sides of the metal plate, which can not only press metal plates of different widths, but also enable the metal plate to be conveyed through the second roller 9 to prevent deviation during transportation. The device can not only fix metal plates of different widths and thicknesses, but also prevent them from deflecting and falling off during transportation, thereby indirectly improving the quality of metal plate bending.
[0028] Among them, when the metal plate is transported, it is transported by a pushing component. The pushing component in the prior art includes an electric telescopic rod and a pushing plate. The metal plate is transported by driving the pushing plate through the electric telescopic rod. This belongs to the prior art and will not be described in detail here.
[0029] At the same time, in order to prevent the side protection plate from getting stuck and becoming uneven when moving, the sliding plate 6 is matched with the slide groove, so that the side limit plate 8 can move smoothly during movement, thereby improving the side clamping effect.
[0030] like Figure 2 and Figure 3 As shown, the elastic component includes a through hole opened on the first connecting plate 7, a movable rod 14 is movably arranged inside the through hole, a limiting block is installed at one end of the movable rod 14, and the other end of the movable rod 14 is connected to the side limiting plate 8, and a spring 15 is arranged on the movable rod 14, and the spring 15 is located between the side limiting plate 8 and the first connecting plate 7.
[0031] When the sliding plate 6 moves, it drives the first connecting plate 7 to move, and the first connecting plate 7 drives the side limiting plate 8 to contact the metal plate. When in contact, the side limiting plate 8 drives the movable rod 14 to move on the first connecting plate 7 and squeeze the spring 15, thereby pressing the metal plate.
[0032] Among them, the purpose of setting the spring 15 is that when the metal plate is located between the first roller 4 and the third roller 12, the side limit plate 8 has been in contact with the metal plate, and the first roller 4 and the third roller 12 have not yet pressed the metal plate. At this time, the side limit plate 8 can be further compressed by the action of the spring 15, so that the first roller 4 and the third roller 12 can press the metal plate.
[0033] It should be noted that: the utility model is designed so that the side limit plate 8 contacts the metal plate first, so that space can be left for operation.
[0034] like Figure 2 and Figure 3 As shown, the driving assembly includes two threaded rods 16 arranged on the base plate 1, and the two threaded rods 16 are each provided with a threaded sleeve 17, one side of the threaded sleeve 17 is connected to the second connecting plate 10, and the top of the two threaded rods 16 is provided with a rotating rod, the two rotating rods are connected by a transmission belt 18, and one of the rotating rods is provided with a motor.
[0035] The motor (not shown) drives the rotating rod to rotate, so that another rotating rod drives another threaded rod 16 to rotate through the transmission belt 18. When the two threaded rods 16 rotate, they drive the threaded sleeve 17 to move the second connecting plate 10 downward to work.
[0036] Among them, a fixing bracket is arranged on the motor, and the fixing bracket is connected to the bottom plate 1, and the motor is fixed by the fixing bracket so as to work.
[0037] The first roller 4, the second roller 9 and the third roller 12 are all provided with smooth surfaces, and the smooth surfaces can reduce the friction force and enable the metal plate to be better transported.
[0038] The length and width of the first through slot 2 and the second through slot are the same, so that the contact area between the first roller 4 and the third roller 12 and the metal plate is the same, which makes the force uniform and prevents the metal plate from being offset due to uneven force when being conveyed.
[0039] The working principle of the utility model is as follows: first, the first roller 4 to be bent is placed on the bottom plate 1, and then the driving component provides power to move the two second connecting plates 10 downward. When the second connecting plate 10 moves downward, it drives the third connecting plate 11 to move the third roller 12 inside the second through groove downward, thereby clamping the metal plate. The metal plate is limited and fixed by the first roller 4 and the third roller 12, which can not only adapt to metal plates of different thicknesses, but also move when pressing to prevent shaking during transportation. At the same time, when the two second connecting plates 10 move downward, the second connecting plate 10 drives the fourth connecting plate 13 to move the sliding plate 6 on the fixed plate 5 inside the slide groove, thereby driving the first connecting plate 7 to make the elastic component drive the side limiting plate 8 to press the two sides of the metal plate, which can not only press metal plates of different widths, but also can convey the metal plate through the second roller 9 to prevent deviation during transportation. The device can not only fix metal plates of different widths and thicknesses, but also prevent them from deflecting and falling off during transportation, thereby indirectly improving the quality of metal plate bending.
[0040] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
