[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0031] like Figure 1 As shown, the utility model provides a device for primary crushing of sintered blocks, including a hydraulic press body 1, on which a crushing platform 2 for crushing sintered blocks is fixedly arranged, a hydraulic cylinder 3 is arranged in the body 1 above the crushing platform 2, and a pressure plate 4 is arranged at the bottom of the piston rod of the hydraulic cylinder 3. The crushing platforms 2 are arranged side by side and close to each other to receive an input platform 5 for the sintered blocks, a discharge port 6 is arranged on the side of the crushing platform 2 away from the input platform 5, a driving member 7 is fixedly arranged on the input platform 5, and a material push plate 8 for pushing the sintered blocks to the discharge port 6 is fixedly arranged at the output end of the driving member 7.

[0032] The crushing of the sintered block is achieved through the pressure plate 4 of the hydraulic press. The industrial single-column hydraulic press has excellent rigidity, and the guiding performance, speed and precision are controllable. It is currently mainly used in sheet metal forming, plastic forming, bending, deep drawing, etc. Most of the blocks formed by sintering are hard but not rigid. Therefore, by improving the structure of the hydraulic press, it can be well applied to the crushing process of the sintered block, and the sintered block can be crushed quickly and effectively.

[0033] like Figure 2 As shown, further, a baffle 9 is provided at the edge of the crushing platform 2 and along the discharging direction. The purpose of the baffle 9 is to prevent the spattering of the sintered block during the crushing process and ensure a certain degree of crushing safety. The material push plate 8 moves to the edge of the crushing platform 2. At this time, the two baffles 9, the material push plate 8 and the discharging port 6 just enclose the operation for crushing the sintered block, and are also just at the edge of the crushing platform 2.

[0034] like Figure 6As shown, first, a driving member 7 is fixedly provided on the input platform 5, and the driving member 7 can be selected from a motor, a pneumatic push rod, an electric push rod, etc. The material push plate 8 is initially located on the input platform 5, and the sintered block is manually placed on the input platform 5. The first movement stroke of the material push plate 8 is to move from the input platform 5 along the discharge direction to the edge of the crushing platform 2, and the sintered block is also pushed into the crushing platform 2 during the movement. The state at this time just forms the working space of the pressure plate 4 as mentioned above. When the pressure plate 4 finishes working and rises to a certain height, the second movement stroke of the material push plate 8 starts to work, that is, it moves from the edge of the crushing platform 2 along the discharge direction to the area of ​​the crushing platform 2. At this time, the material push plate 8 pushes the crushed sintered block from the crushing platform 2 to the discharge port 6. Finally, the material push plate 8 returns to the initial position through the third movement stroke, that is, from the crushing platform 2 back to the input platform 5.

[0035] like Figure 1 As shown, further, in order to make the material push plate 8 push smoothly in the crushing platform 2, a guide groove 91 is provided on the baffle 9 along the discharging direction, and guide bosses 81 adapted to the shape of the guide groove 91 are provided on both sides of the material push plate 8. Through the cooperation of the guide boss 81 and the guide groove 91, the material push plate 8 can slide more smoothly and accurately in the second movement stroke mentioned above, and the efficiency of pushing the crushed sintered blocks is higher.

[0036] like Figure 3 As shown, further, a soft sheet-like plastic scraper 82 is provided below the material push plate 8. The purpose is to prevent scratches and damage caused by hard contact with the crushing platform 2, and to more conveniently push smaller fine particles out of the crushing platform 2.

[0037] like Figure 5 As shown, further, the discharge port 6 is in an eight-shaped shape, and the opening gradually becomes smaller along the direction of the discharge, and shows a downward trend. This arrangement is for better collection of the crushed sintered block fragments. A material collecting device can be placed below the narrow opening of the eight-shaped discharge port 6, or it can be directly connected to the secondary crushing equipment. A socket 61 is provided above the wide mouth of the discharge port 6, and an adjustment plate 62 for adjusting the opening size at the wide mouth of the discharge port 6 is provided in the socket 61. Threaded holes 63 are provided on both sides of the wide mouth of the discharge port 6, and the adjustment plate 62 is fixed by passing bolts 64 through the threaded holes 63. With this arrangement, in order to meet the secondary crushing requirements, it can be achieved by adjusting the height of the plate 62, that is, the adjustment plate 62 can be adjusted to make the opening at the wide mouth of the discharge port 6 less than 50㎜. The adjustment plate 62 can also be used to prevent the blockage problem caused by the crushing process.

[0038] Furthermore, a tungsten carbide coating is provided on the surface where the pressure plate 4 and the crushing platform 2 are pressed together, and a tungsten carbide coating is provided on the surface of the baffle plate 9 and the material push plate 8 close to the sintered block. The tungsten carbide coating has good corrosion resistance and can also enhance the hardness of the surfaces of the components when in contact.

[0039] In summary, using the characteristics of the hydraulic press to crush the sintered block can achieve rapid crushing of the block material, high crushing efficiency, good crushing effect, no pollution and loss in the crushing process, and controllable particle size of the crushed material. The pressure plate 4 is slowly dropped vertically by the liquid pressure, and the depth of the pressure plate drop can be set according to the particle size required for crushing. Generally, the distance between the pressure plate 4 and the crushing platform 2 is controlled to be between 10 and 40 mm. Baffles 9 are set around the crushing platform 2 to prevent material splashing during the crushing process. The different movement strokes of the material push plate 8 can realize the functions of pushing materials, assisting in enclosing the working space, and pushing out powder. The input platform 5 set can also consider using a conveyor belt, or an external conveyor belt.

[0040] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
