Description

Technical Field

[0001] This utility model relates to the field of briquetting machine technology, specifically a pre-compression briquetting machine. Background Technology

[0002] A metal scrap briquetting machine is a specialized piece of equipment used to compress metal scrap or shavings into briquette-like products. It is widely used in metal recycling, metallurgy, machinery manufacturing, and environmental protection industries. With the acceleration of industrialization, the large amount of waste generated during metal processing places immense pressure on the environment. The metal scrap briquetting machine effectively solves this problem through its efficient pressing process. It can transform difficult-to-process metal scrap into reusable products and effectively reduce environmental pollution from waste.

[0003] Generally, briquetting machines often use hydraulic compression to form briquettes in one go. During the forming process, a large number of metal scraps are pressed together at once. The stress on the metal scraps is relatively concentrated, so the load on the hydraulic cylinder is relatively large, which can easily cause blockage and make production inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a pre-compression briquetting machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pre-compression briquetting machine includes a briquetting mechanism and a pre-compression mechanism, wherein the pre-compression mechanism is mounted on the briquetting mechanism.

[0007] The pressing mechanism includes a frame, a mold, a column, and a first hydraulic cylinder. The column is fixedly connected to the frame, and the first hydraulic cylinder is mounted on the top of the column via a mounting bracket. The mold is disposed on the frame, and the output end of the first hydraulic cylinder passes through the mold and extends into the inner cavity of the mold.

[0008] The pre-compression mechanism includes a fixed frame, a pre-compression chamber, a second hydraulic cylinder, and a third hydraulic cylinder. The fixed frame is fixedly connected to one side of the machine frame. The pre-compression chamber is welded to the fixed frame. The second hydraulic cylinder is fixedly connected to the fixed frame via a bracket. The output end of the second hydraulic cylinder passes through the pre-compression chamber and is inserted into the inside of the pre-compression chamber. The third hydraulic cylinder is bolted to one side of the pre-compression chamber. The output end of the third hydraulic cylinder extends into the interior of the pre-compression chamber. One end of the pre-compression chamber is connected to the mold.

[0009] In one embodiment, the second hydraulic cylinder and the third hydraulic cylinder are arranged in an L-shape, and the included angle between the second hydraulic cylinder and the third hydraulic cylinder is ninety degrees.

[0010] In one embodiment, a rectangular pressure plate is installed at the output end of the second hydraulic cylinder, and an L-shaped pressure plate is installed at the output end of the third hydraulic cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes a pre-compression mechanism and a briquetting mechanism in conjunction to compress metal scrap into blocks in a segmented manner. The pre-compression mechanism initially compacts the metal scrap, while the briquetting mechanism completes the final shaping under higher pressure. This layered pressing method effectively increases the density of the blocks and reduces porosity. In the first pressing, the stress of the metal scrap is more evenly distributed, thus reducing stress concentration in the second pressing. This effectively reduces material blockage and rework caused by improper processes. Furthermore, the two-step pressing allows for flexible adjustment of parameters at each step, such as pressure, time, and speed, to adapt to different types of metal scrap and shaping requirements, thereby improving production flexibility.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] Please see Figures 1 to 3 This utility model provides a technical solution:

[0021] A pre-compression briquetting machine includes a briquetting mechanism and a pre-compression mechanism, with the pre-compression mechanism mounted on the briquetting mechanism. The pre-compression mechanism is used for initial compression of metal scraps, while the briquetting mechanism is used for further compression of the metal scraps. Through a two-step compression process, the first step initially compacts the metal scraps, and the second step completes the final shaping under higher pressure. This layered compression method effectively increases the density of the briquettes and reduces porosity. In the first compression, the stress on the metal scraps is more evenly distributed, thus reducing stress concentration in the second compression. This effectively reduces material blockage and rework caused by improper processes. Furthermore, the two-step compression allows for flexible adjustment of parameters at each step, such as pressure, time, and speed, to adapt to different types of metal scraps and shaping requirements, thereby improving production flexibility.

[0022] The briquetting mechanism includes a frame 11, a mold 12, a column 13, and a first hydraulic cylinder 14. The column 13 is fixedly connected to the frame 11. The first hydraulic cylinder 14 is mounted on the top of the column 13 via a mounting bracket. The mold 12 is set on the frame 11. The output end of the first hydraulic cylinder 14 passes through the mold 12 and extends into the inner cavity of the mold 12. The briquetting mechanism is driven by the output of the first hydraulic cylinder 14 at the top. Inside the mold 12, the metal block pre-pressed by the pre-pressing mechanism is further pressed by downward pressure.

[0023] The pre-compression mechanism includes a fixed frame 21, a pre-compression chamber 22, a second hydraulic cylinder 23, and a third hydraulic cylinder 24. The fixed frame 21 is fixedly connected to one side of the frame 11. The pre-compression chamber 22 is welded to the fixed frame 21. Metal scraps are initially compressed into blocks inside the pre-compression chamber 22. The second hydraulic cylinder 23 is fixedly connected to the fixed frame 21 via a bracket. The output end of the second hydraulic cylinder 23 passes through the pre-compression chamber 22 and is inserted into the inside of the pre-compression chamber 22. The third hydraulic cylinder 24 is bolted to one side of the pre-compression chamber 22. The output end of the third hydraulic cylinder 24 extends into the interior of the pre-compression chamber 22. One end of the pre-compression chamber 22 is connected to the mold. Specifically, within the pre-compression chamber 22, the end of the third hydraulic cylinder 24 is an L-shaped pressure plate, which can push the metal material to aggregate together. The rectangular pressure plate of the second hydraulic cylinder 23 pushes the metal scrap material to press onto the L-shaped pressure plate of the third hydraulic cylinder 24 for extrusion molding. After the L-shaped pressure plate retracts, the second hydraulic cylinder 23 is restarted to push the initially formed block into the mold 12 for a second pressing. The pressure, time, and speed parameters of the hydraulic cylinders can be set for each of the two processes to adapt to different types of metal scraps and molding requirements, thereby improving production flexibility.

[0024] Furthermore, the second hydraulic cylinder 23 and the third hydraulic cylinder 24 are arranged in an L-shape, with an included angle of 90 degrees between them. A rectangular pressure plate is installed at the output end of the second hydraulic cylinder 23, and an L-shaped pressure plate is installed at the output end of the third hydraulic cylinder 24. The L-shaped pressure plate can not only push the material into the pre-compression chamber 22, but also serve as the force arm for the first compression. After the first compression, the third hydraulic cylinder 24 drives the L-shaped pressure plate to retract, without affecting the second hydraulic cylinder 23's pushing of the pressure block into the mold 12.

[0025] Furthermore, a feed inlet is provided at the top of the pre-compression chamber 22, and a feed hopper 25 is installed at the feed inlet at the top of the pre-compression chamber 22. Metal scraps and debris are fed into the pre-compression chamber 22 through the feed hopper 25.

[0026] Furthermore, it also includes a hydraulic pump station 31, the input and output ends of which are connected to the column 13, the second hydraulic cylinder 23, and the third hydraulic cylinder 24. The hydraulic pump station 31 is used to provide the hydraulic system.

[0027] The working principle of this utility model is as follows: Inside the pre-compression chamber 22, the end of the third hydraulic cylinder 24 is an L-shaped pressure plate, which can push the metal material to aggregate together. The rectangular pressure plate of the second hydraulic cylinder 23 pushes the metal scrap material to press onto the L-shaped pressure plate of the third hydraulic cylinder 24 for extrusion molding. After the L-shaped pressure plate retracts, the second hydraulic cylinder 23 starts again, pushing the initially formed block into the mold 12 for a second pressing. The block pressing mechanism is driven by the output of the first hydraulic cylinder 14 at the top. Inside the mold 12, the metal block formed by the pre-compression mechanism is further pressed by the downward pressure. The pressure, time and speed parameters of the hydraulic cylinder can be set for the two processes respectively to adapt to different types of metal scrap and molding requirements, thereby improving the flexibility of production.
