Description

Technical Field

[0001] The utility model belongs to the technical field of die pressing processing equipment, and particularly relates to a die pressing device. Background Art

[0002] Calcium carbide board, also known as Norman base board, is a high-density fiberboard material, and its main raw materials are wood or plant fibers. This kind of board is processed by high temperature and high pressure, and has the characteristics of wear resistance, water resistance, fire resistance, corrosion resistance, etc., so it is widely used in the decoration industry and construction projects.

[0003] In modern industry, the calcium carbide method is mainly used to prepare calcium carbide. This method uses coke and limestone to react in an electric furnace to obtain calcium carbide. The production process of calcium carbide board also needs to go through steps such as batching and mixing, forming, curing, cutting and grinding on the basis of calcium carbide preparation. Among them, the forming step is to send the mixed material into a forming machine for pressing to form a preliminary shape of the calcium carbide board. A die pressing device is required in this process. However, in the existing calcium carbide board die pressing devices, the punch and the die generally correspond one by one. In the forming process, after a calcium carbide board is pressed and formed, it often needs to go through operations such as demoulding, transportation, and replenishing materials before the next calcium carbide board can be pressed. The pressing interval between two calcium carbide boards is relatively long, resulting in low production efficiency of calcium carbide boards. For this reason, this application proposes a die pressing device. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a die pressing device, aiming to solve the technical problem that the pressing interval between two calcium carbide boards is relatively long and the efficiency is low in the forming process of calcium carbide boards by the die pressing device in the prior art.

By this structural method, the driving mechanism is used to drive the turntable 2 to rotate, so that a plurality of lower die bodies 3 on the turntable 2 are sequentially matched with the pressing die mechanism 4 to press the calcium carbide plate. And during the process of pressing and forming the calcium carbide plate by one of the lower die bodies 3, the remaining lower die bodies 3 can perform operations such as demoulding and feeding, realizing the continuous pressing process of the calcium carbide plate, significantly shortening the long pressing interval time between two calcium carbide plates, and effectively improving the pressing and forming efficiency of the calcium carbide plate.

[0028] As a preferred technical solution in this embodiment, the driving mechanism includes a driven gear 11 rotatably mounted on the base 1 and a driving gear 12. The turntable 2 is fixedly mounted on the driven gear 11, and the driving gear 12 meshes with the driven gear 11. A driving gear 11 for driving the driving gear 12 to rotate is mounted on the base 1. Starting the driving motor 13 drives the driving gear 12 to rotate, and by using the meshing transmission between the driving gear 12 and the driven gear 11, the turntable 2 can be driven to rotate. Among them, the radius of the driven gear 11 is larger than the radius of the driving gear 12, which is convenient for controlling the rotation of the turntable 2.

[0029] As a preferred technical solution in this embodiment, the pressing die mechanism 4 includes a fixed arm 7 fixed on the base 1, a hydraulic arm 8 vertically mounted on the fixed arm 7, and an upper die body 9 mounted on the telescopic end of the hydraulic arm 8. The upper die body 9 can at least be aligned with one of the lower die bodies 3. When the lower die body 3 is aligned with the upper die body 9, starting the hydraulic arm 8 to push the upper die body 9 downward to close the die with the lower die body 3 can press and form the calcium carbide plate.

[0030] Further, in this embodiment, positioning ribs 15 are provided at the bottoms of both side walls of the lower die body 3, and positioning stop bars 14 that are fastened to the positioning ribs 15 are fixed on the turntable 2, which facilitates the pulling of the lower die body 3. A connecting plate 5 is provided on one side wall of the lower die body 3 facing the middle of the turntable 2, and a positioning member 6 for positioning and clamping the connecting plate 5 is provided on the turntable 2. The positioning member 6 includes a housing 17 fixed on the turntable 2. A slot 18 that can accommodate the horizontal insertion of the connecting plate 5 is provided at the top of the housing 17. A baffle 21 is movably embedded in the housing 17. A pin rod 23 is provided at the top of the baffle 21. A pin hole 16 that can accommodate the pin rod 23 to pass through is provided on the connecting plate 5. A spring 22 is provided between the baffle 21 and the inner bottom wall of the housing 17. A sliding groove 19 is provided on the side wall of the housing 17. A push plate 20 is horizontally inserted through the sliding groove 19. The push plate 20 is fixedly connected to the baffle 21. Through the clamping cooperation between the connecting plate 5 and the positioning member 6, the lower die body 3 can be temporarily positioned on the turntable 2. After pressing the push plate 20 to push the baffle 21 downward, the pin rod 23 disengages from the pin hole 16 on the connecting plate 5, and the lower die body 3 can be pulled away from the turntable 2, which facilitates the collection and transfer of the calcium carbide plates formed by pressing.

[0031] Further, a bottom plate 24 is movably arranged at the inner bottom of the lower die body 3, and a support table 25 for supporting the bottom plate 24 is arranged at the bottom of the inner side wall of the lower die body 3, which facilitates the demoulding operation of the calcium carbide plates.

[0032] As a preferred technical solution in this embodiment, an auxiliary pressing strip 10 is horizontally fixed on the side wall of the upper die body 9 facing the middle of the turntable 2. The auxiliary pressing strip 10 is aligned with the push plate 20 on one of the housings 17. During the process of pressing the calcium carbide plates by the cooperation of the upper die body 9 and one of the lower die bodies 3, the upper die body 9 drives the auxiliary pressing strip 10 to press downward, and the corresponding push plate 20 can be pressed downward, so that the corresponding lower die body 3 can be directly pulled out for demoulding and transfer operations, which is more convenient for the pressing and forming process of the calcium carbide plates.

[0033] Working principle: During use, start the drive motor 13 to drive the rotation of the driving gear 12. Utilize the meshing transmission between the driving gear 12 and the driven gear 11 to drive the rotation of the turntable 2, so that multiple lower die bodies 3 on the turntable 2 sequentially pass below the upper die body 9. And when the lower die body 3 moves below the upper die body 9, start the hydraulic arm 8 to push the upper die body 9 downward to close the die with the lower die body 3, realizing the forming and pressing of the calcium carbide plate. And during the process of the lower die body 3 pressing and forming the calcium carbide plate, the other lower die bodies 3 can perform operations such as demoulding and feeding, realizing the continuous pressing process of the calcium carbide plate, significantly shortening the relatively long pressing interval time between two calcium carbide plates, improving the pressing and forming efficiency of the calcium carbide plate. Through the clamping cooperation between the connecting plate 5 and the positioning member 6 on the lower die body 3, the lower die body 3 can be temporarily positioned on the turntable 2. After pressing the push plate 20 to push the baffle 21 downward, the pin rod 23 disengages from the pin hole 16 on the connecting plate 5, and the lower die body 3 can be withdrawn from the turntable 2, facilitating the collection and transfer of the pressed and formed calcium carbide plate. And the setting of the inner bottom plate 24 and the support table 25 in the lower die body 3 facilitates the demoulding operation and can further improve the production efficiency of the calcium carbide plate.
