[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0025] The following gives specific embodiments.

[0026] Such as Figures 1-5As shown in the figure, a waste heat recycling device for a hydraulic forming machine includes a forming machine main body 1; a pressing plate 11 is slidably connected to the middle of the forming machine main body 1; a circulating machine main body 12 is installed at the end of the forming machine main body 1; a storage box 13 is fixedly connected to the middle of the circulating machine main body 12; a flip cover 14 is installed on the top of the storage box 13; a rotating shaft 15 is rotatably connected to the middle of the storage box 13; a screw conveyor 16 is fixedly connected to the middle of the rotating shaft 15; a limiting groove 17 is formed in the middle of the screw conveyor 16; a rolling ball 18 is slidably connected to the inner wall of the limiting groove 17; the top of the rolling ball 18 is rotatably connected to a connecting frame 19, and the end of the connecting frame 19 is fixedly connected to the side wall of the pressing plate 11; a plurality of stirring rods 110 are fixedly connected to the middle of the rotating shaft 15, and the plurality of stirring rods 110 are arranged inside the storage box 13; during work, the staff needs to install the whole forming machine main body 1 in the working area, then connect the power supply to the forming machine main body 1, place the object to be processed on the middle of the forming machine main body 1, and start the pressing plate 11 switch to carry out the processing work. The waste water generated by the working of the forming machine main body 1 can be transferred to the inside of the storage box 13 through a pipeline for collection and waste heat recovery treatment. By arranging a rotatable rotating shaft 15 in the middle of the storage box 13, when the pressing plate 11 moves up and down as a whole, the rolling ball 18 that will not fall off inside the screw conveyor 16 is matched, so that the connecting frame 19 will squeeze the middle of the screw conveyor 16. With the setting of its arc surface, the rolling ball 18 rolls on the inner wall of the screw conveyor 16. At this time, the screw conveyor 16 and the rotating shaft 15 as a whole will rotate. Using the arranged plurality of stirring rods 110 to stir the liquid inside the storage box 13, this step is combined with the arranged rotating rotating shaft 15, which can make the liquid on the inner wall of the storage box 13 flow, and raise some precipitated impurities, reducing the precipitation and caking of some impurities on the inner wall of the storage box 13, so as to avoid the problem of low precision during subsequent waste heat recovery. Moreover, the arranged plurality of stirring rods 110 can improve the uniformity of the liquid mixing inside the storage box 13 and reduce the problem of temperature difference caused by stratification.

[0027] As Figure 2 , 4As shown in FIGS. 4 and 5, a support plate 2 is fixedly connected to the bottom of the rotating shaft 15; two groups of brackets 21 are fixedly connected to the bottom of the support plate 2; a receiving rod 22 is torsionally connected to the top of the bracket 21; a filter screen 23 is fixedly connected to the middle of the receiving rod 22; two groups of first elastic ropes 24 are fixedly connected to the bottom of the support plate 2; a counterweight ball 25 is fixedly connected to the end of the first elastic rope 24, and the counterweight ball 25 is slidably arranged on the inner wall of the bracket 21; the counterweight ball 25 is fixedly connected to the end of the filter screen 23; during operation, by arranging the support plate 2 at the bottom of the rotating shaft 15, the support plate 2 can support the two groups of brackets 21. When the rotating shaft 15 is stationary as a whole, with the cooperation of the first elastic rope 24 and the torsion generated by the receiving rod 22, the counterweight ball 25 and the filter screen 23 as a whole can be reset and received. When the rotating shaft 15 rotates as a whole, with the cooperation of the counterweight ball 25 and the centrifugal force, the counterweight ball 25 can be displaced towards the inner wall of the storage box 13, and the filter screen 23 as a whole can be unfolded, so that the filter screen 23 can clean and collect some impurities contained in the liquid in the middle. This step, in cooperation with the filter screen 23, can further improve the cleanliness of the liquid inside the storage box 13, reduce the problem that some impurities accumulate and cake on the inner wall of the flow pipeline when the waste water is recycled, making it troublesome to clean later. Moreover, the arranged receiving rod 22 can wind up the filter screen 23 with more impurities in the middle, reducing the problem of secondary detachment of impurities.

[0028] As Figure 5 shown, a top plate 3 is fixedly connected to the bottom of the support plate 2; two groups of limit plates 31 are fixedly connected to the middle of the top plate 3, and the limit plates 31 are arc-shaped; a second elastic rope 32 is fixedly connected to the inner wall of the limit plate 31; during operation, by arranging the top plate 3 in the middle of the support plate 2, the top plate 3 can support the two groups of limit plates 31. When the first elastic rope 24 is in a loose state as a whole, the middle of the second elastic rope 32 can block the first elastic rope 24. This step, in cooperation with the top plate 3, can reduce the problem that the two groups of first elastic ropes 24 are wound together when in a loose state, and the arc-shaped limit plates 31 can further limit the first elastic rope 24.

[0029] As Figure 5 shown, multiple groups of springs 4 are fixedly connected to the bottom of the support plate 2; a sheath 41 is fixedly connected to the bottom of the spring 4, and the inner wall of the sheath 41 is in contact with the middle of the first elastic rope 24; during operation, by arranging multiple springs 4 at the bottom of the support plate 2, when the middle of the first elastic rope 24 is pulled, the first elastic rope 24 will deeply contact the inner wall of the sheath 41 and drive the middle of the multiple groups of springs 4 to deform. This step, in cooperation with the soft material sheath 41, can protect the bent part of the first elastic rope 24, and at the same time, the pulled spring 4 can reset the edge of the first elastic rope 24.

[0030] AsFigure 1 and 2 As shown in 2 , a support rod 5 is fixedly connected to the top of the rotating shaft 15; a shielding plate 51 is fixedly connected to the top of the support rod 5, and the top of the shielding plate 51 is inclined. During operation, by providing the support rod 5 at the top of the rotating shaft 15, the support rod 5 can support the shielding plate 51, and when the rotating shaft 15 rotates, the impurities accumulated on the top of the shielding plate 51 can be thrown away. This step, combined with the provided shielding plate 51, can reduce the amount of impurities that the shielding plate 51 can block when the main body 1 of the molding machine works in a dusty environment, thereby improving the cleanliness of the inner wall of the limiting groove 17 and reducing the resistance and wear generated on the surface of the rolling ball 18.

[0031] As Figure 4 shown in Figure 4 , a rubber part 6 is fixedly connected to the bottom of the top plate 3. During operation, by providing the rubber part 6 at the bottom of the top plate 3, when the edge of the first elastic rope 24 falls, it will deeply contact the middle of the rubber part 6. This step, combined with the provided rubber part 6, can increase the counterweight of the rotating shaft 15 and at the same time reduce the wear on the edge of the first elastic rope 24.

[0032] As Figure 2 shown in Figure 2 , a reinforcing part 7 is fixedly connected to the outer wall of the connecting frame 19, and the end of the reinforcing part 7 is fixedly connected to the side wall of the pressing plate 11. During operation, by providing the reinforcing part 7 in the middle of the connecting frame 19, the reinforcing part 7 can reinforce the middle of the connecting frame 19. This step, combined with the provided reinforcing part 7, can reduce the problem of bending and deformation in the middle of the connecting frame 19 after long-term use and improve the service life of the connecting frame 19.

[0033] Working principle: The main body 1 of the molding machine is integrally installed in the working area. After connecting the power supply to the main body 1 of the molding machine, the object to be processed is placed on the middle part of the main body 1 of the molding machine, and after starting the switch of the pressing plate 11, the processing work is carried out. The wastewater generated during the operation of the main body 1 of the molding machine can be transferred through a pipeline to the inside of the storage box 13 for collection and waste heat recovery treatment. By arranging a rotatable rotating shaft 15 in the middle of the storage box 13, when the pressing plate 11 moves up and down as a whole, the rolling ball 18 that will not fall off inside the auger 16 is cooperated, so that the connecting frame 19 will squeeze the middle part of the auger 16, and with the setting of its arc surface, the rolling ball 18 rolls on the inner wall of the auger 16. At this time, the auger 16 and the rotating shaft 15 as a whole will rotate, and the liquid inside the storage box 13 is stirred by using a plurality of stirring rods 110 arranged. By arranging a support plate 2 at the bottom of the rotating shaft 15, the support plate 2 can support the two groups of brackets 21. When the rotating shaft 15 is stationary as a whole, with the torsion generated by the first elastic rope 24 and the storage rod 22, the counterweight ball 25 and the filter screen 23 can be reset and stored as a whole. When the rotating shaft 15 rotates as a whole, under the action of the counterweight ball 25 and the centrifugal force, the counterweight ball 25 can be displaced towards the inner wall of the storage box 13, and the filter screen 23 is unfolded as a whole, so that the filter screen 23 can clean some impurities contained in the liquid and collect them in the middle part. By arranging a top plate 3 in the middle of the support plate 2, the top plate 3 can support the two groups of limiting plates 31. When the first elastic rope 24 is in a loose state as a whole, the middle part of the second elastic rope 32 can block the first elastic rope 24. By arranging a plurality of springs 4 at the bottom of the support plate 2, when the middle part of the first elastic rope 24 is pulled, the first elastic rope 24 will deeply contact the inner wall of the sheath 41 and drive the middle parts of the multiple springs 4 to deform. By arranging a support rod 5 at the top of the rotating shaft 15, the support rod 5 can support the baffle plate 51, and when the rotating shaft 15 rotates, the impurities accumulated on the top of the baffle plate 51 can be thrown away. By arranging a rubber part 6 at the bottom of the top plate 3, when the edge of the first elastic rope 24 falls, it will deeply contact the middle part of the rubber part 6. By arranging a reinforcement part 7 in the middle of the connecting frame 19, the reinforcement part 7 can reinforce the middle part of the connecting frame 19.
