Description

Technical Field

[0001] The utility model relates to the technical field of stamping and forming devices, in particular to a wave pressing device for riveted box plates. Background Art

[0002] The corrugations of the plate of the riveted box are generally formed by stamping with a wave pressing device. The existing wave pressing device includes a base, a bracket, a cylinder and a wave pressing mold. The bracket is fixed to the top surface of the base, and the cylinder is fixed to the bracket. The wave pressing mold is used to form the corrugations of the plate and includes an upper mold and a lower mold located below the upper mold. The upper mold is connected to the push rod of the cylinder, and the lower mold is fixed to the top surface of the base. When stamping the corrugations of the plate, the plate is first placed in the wave pressing mold (i.e., the loading process), and then the cylinder drives the upper mold to move downward and close the mold with the lower mold to stamp the corrugations on the plate. After the stamping is completed, the plate with the corrugations is taken out (i.e., the unloading process). However, the plate is prone to scratches when it is stamped and formed by the above-mentioned wave pressing device, which affects the product quality. Utility Model Content

[0021] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0022] like Figures 1 to 3 As shown, an embodiment of the utility model provides a riveted box plate corrugation device for stamping and forming plate corrugations of the riveted box, comprising a base 1, a bracket 2, multiple groups of drive structures 3 and two material guide structures 4, and the bracket 2, multiple groups of drive structures 3 and two material guide structures 4 are installed on the base 1.

[0023] The base 1 extends forward and has a lower mold area 11 on its top surface, and the lower mold area 11 is used to install the lower mold 200 of the pressure wave mold. The bracket 2 is located outside the lower mold area 11 and is fixed to the top surface of the base 1 by bolts. The bracket 2 has a mounting portion 21 located above the lower mold area 11. Specifically, the bracket 2 includes a plurality of frames 20, and the plurality of frames 20 are arranged at equal distances in the front-to-back direction. The top of each frame 20 forms a mounting portion 21. More specifically, the mounting portion 21 is a crossbeam of the frame 20, which extends in the left-right direction.

[0024] A plurality of drive structures 3 are mounted on the mounting portion 21 and are evenly distributed along the front-to-back direction, and one drive structure 3 is fixed on one mounting portion 21. Each drive structure 3 includes a drive unit 31 connected to the mounting portion 21, and each drive unit 31 has a push rod 32 that can be extended up and down. The drive unit 31 of each drive structure 3 is used to install an upper mold 100 located above the lower mold 200. In this embodiment, the drive unit 31 is an oil cylinder, and each drive structure 3 is provided with four oil cylinders. The oil cylinder is fixed to the top surface of the mounting portion 21 by bolts, and the lower end of the push rod 32 thereof passes downward through the mounting portion 21 to be connected to the upper mold 100. The lower end of the push rod 32 is provided with a connecting plate (not numbered), and the connecting plate is used to connect to the lower mold 200.

[0025] The two material guiding structures 4 are respectively located outside the front and rear sides of the lower mold area 11 and include a mounting seat 41 located outside the lower mold area 11 and fixed to the top surface of the base 1. The upper end of the mounting seat 41 is rotatably connected to a guide member 42 located outside the lower mold area 11. The guide member 42 can accurately and quickly guide the plate into or out of the wave pressing mold, and the friction force generated between the guide member and the plate is rolling friction, which reduces the friction force generated by the plate during the loading and unloading process, thereby avoiding scratching the plate, ensuring product quality and improving production efficiency.

[0026] In order to simplify the structure and facilitate processing, specifically, the mounting seat 41 includes two fixed blocks 411 arranged opposite to each other in the left and right directions, the two fixed blocks 411 are fixed to the top surface of the base 1 by screws and a connecting shaft 412 is fixed therebetween. More specifically, a mounting groove 4111 is downwardly provided on the top surface of each fixed block 411, the mounting groove 4111 penetrates the fixed block 411 from left to right, and the two ends of the connecting shaft 412 are respectively matched with the two mounting grooves 4111 with clearance; of course, in other embodiments, a mounting hole (not shown) penetrating it from left to right can also be provided at the upper end of each fixed block 411, and the two ends of the connecting shaft 412 are respectively matched with the two mounting holes.

[0027] In this embodiment, the guide member 42 is rotatably connected to the connecting shaft 412. Specifically, the guide member 42 is a roller, which is rotatably connected to the connecting shaft 412 through a bearing and has multiple rollers. The multiple rollers are distributed in the left and right directions and are higher than the top surface of the fixed block 411, and the heights of the multiple rollers are equal to or higher than the top surface of the lower mold 200 to facilitate guiding.

[0028] In order to further improve the quality of sheet stamping, the bracket 2 or the base 1 is provided with a solenoid valve (not shown) corresponding to each group of driving structures 3. In this embodiment, the solenoid valve is fixed on the frame 20. Of course, in other embodiments, the solenoid valve can also be fixed on the base 1. The specific installation position can be selected according to actual needs. Each solenoid valve is electrically connected to the driving unit 31 of the corresponding group of driving structures 3, so that the driving unit 31 is opened or closed under the control of the solenoid valve. When the corrugation (blind wave or through wave) of the sheet is stamped, the solenoid valves arranged in the front-to-back direction sequentially control the driving unit 31 electrically connected thereto to move downward in the front-to-back order to drive the upper mold 100 to move downward, so that the upper mold 100 and the lower mold 200 are closed to achieve stamping, that is, the corrugation of the sheet is stamped in sequence, which can prevent the size from being affected due to the extension deformation during stamping, and can take into account the through wave and blind wave stamping of the sheet.

The material guide structure includes a mounting seat located outside the lower mold area and fixed to the top surface of the base. The upper end of the mounting seat is rotatably connected to a guide member located outside the lower mold area. The guide member can accurately and quickly guide the plate into or out of the wave pressing mold, and the friction force generated between the guide member and the plate is a rolling friction force, which reduces the friction force generated by the plate during the loading and unloading process, thereby avoiding scratching the plate and ensuring product quality. The utility model of the riveted box plate wave pressing device has the characteristics of simple structure, easy installation and convenient loading and unloading.
