[0014] Figure 1 A schematic diagram of the structure of an airbag tension table provided by this utility model. Detailed Implementation

[0015] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0016] like Figure 1 The diagram shows a structural schematic of an airbag-type tension table provided by this utility model. The airbag-type tension table includes a frame 10, a drive mechanism 20 connected to the frame 10, a guide rail 30 fixedly connected to the frame 10, an upper pressure platform mechanism 40 slidably disposed on the guide rail 30 and connected to the drive mechanism 20, and a lower pressure platform mechanism 50 disposed on the side of the frame 10 facing the upper pressure platform mechanism 40. It is conceivable that the airbag-type tension table also includes other functional structures, such as sliders, locking blocks, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0017] The frame 10 is fixedly mounted on the ground, providing the main support function.

[0018] The drive mechanism 20 includes a drive cylinder 21 mounted on the frame 10, and a connector 22 connected to the movable end of the drive cylinder 21. The other end of the connector 22 is connected to the upper pressure platform mechanism 40.

[0019] The guide rail 30 is used for the upper pressure platform mechanism 40 to slide along itself.

[0020] The upper pressing table mechanism 40 comprises an upper pressing table 41 slidingly arranged on the guide rail 30 and connected with the connecting piece 22 at one end, and an upper felt 42 arranged on the end face of the upper pressing table 41 towards the lower pressing table mechanism 50.

[0021] The end face of the upper pressing table 41 towards the lower pressing table mechanism 50 is horizontally arranged. The two ends of the upper felt 42 are fixedly connected. An upper inclined surface 43 is arranged on the side of the upper felt 42 away from the rack 10. The upper inclined surface 43 can play a role of preliminary guiding. The upper felt 43 can protect the surface of the plate and reduce the rate of defective products.

[0022] The lower pressing table mechanism 50 comprises a lower pressing table 51, an air bag assembly 52 arranged on the end face of the lower pressing table 51 towards the upper pressing table mechanism 40, a counterweight 53 arranged on the end face of the lower pressing table 51 away from the rack 10, and a lower felt 54 covering the lower pressing table 51 and the air bag assembly 52.

[0023] The two end faces of the lower pressing table 51 adjacent to the upper pressing table 41 are parallel to each other. A lower inclined surface 55 is arranged on the side of the lower pressing table 51 away from the rack 10, which plays a guiding role after covering the lower felt 54. The air bag assembly 52 comprises an air bag accommodating groove 521 arranged on the end face of the lower pressing table 51 towards the upper pressing table 41, and an air bag 522 fixedly arranged in the air bag accommodating groove 521. The two ends of the air bag 522 are embedded in the side walls of the air bag accommodating groove 521, which plays a fixing role. The air bag 522 is inflated by an external air pump and other devices, which is a prior art and will not be described here.

[0024] The counterweight 53 is fixedly arranged on the side of the lower felt 54 close to the side of the lower pressing table 51 close to the rack 10, and the other end is arranged around the counterweight 53. A layer of magnetic material can be arranged on the surface of the counterweight 53, so that the counterweight 53 is adsorbed to the side wall of the lower pressing table 51, so that the lower felt 54 can always be kept in a tight state when covering the lower pressing table 51 and the air bag assembly 52.

[0025] In use, the metal plate is placed on the lower pressing table 51, and the drive mechanism 20 pushes the upper pressing table 41 to press down until it is in contact with the metal plate. Then the air bag 522 is inflated to make it bulge, and the lower felt 54 is lifted up, thereby increasing the adhesion of the lower felt 54 to the plate and improving the clamping effect, so that the plate can be better kept in tension.

[0026] Compared with the prior art, the air bag type tension platform provided by the utility model through setting down the pressing table mechanism 50. One air bag accommodating groove 521 is arranged on the down pressing table 51 in the down pressing table mechanism 50, and an air bag 522 is arranged in the air bag accommodating groove 521. One down felt 54 is covered on the down pressing table 51 and the air bag 522. The down felt 54 covered on the down pressing table 51 and the air bag 522 is lifted up by inflating the air bag 522 to make it swell, and the adhesion of the down felt 54 and the plate is improved.

[0027] The above is only the preferred embodiment of the utility model, and is not used for limiting the protection scope of the utility model, and any modification, equivalent replacement or improvement etc. in the utility model spirit are covered in the claim range of the utility model.
