Description

Technical Field

[0001] This utility model belongs to the field of mechanical engineering technology, specifically a briquetting machine for ferrous metal casting. Background Technology

[0002] A briquetting machine is a machine that uses a specific working medium to transmit pressure and compress different scrap metal raw materials into shapes. The working medium for transmitting pressure is mainly of two types: mechanical transmission and fluid transmission. Among them, the mechanical transmission type includes friction presses that transmit power and motion through friction between machine parts, and presses that transmit power or motion through the meshing of driving and driven parts or with the help of intermediate parts.

[0003] The working principle of a briquetting machine is mainly based on mechanical force or fluid pressure transmission. By applying high pressure to the material, its volume is reduced and its density is increased, eventually forming it into a block.

[0004] Currently, after long-term observation, it has been found that the traditional feeding method of briquetting machines mostly relies on gravity conveying. Regardless of the amount of material in the hopper, the feeding speed always depends on the effect of gravity. When the material in the hopper is too high, the channel may be blocked due to excessive instantaneous pressure. When the material is less, the feeding speed will be too slow, reducing the overall production efficiency and making it impossible to achieve flexible control. Therefore, a briquetting machine for ferrous metal casting is proposed to address the above problems. Utility Model Content

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Specific implementation examples are given below.

[0028] Please see Figure 1 , Figure 2 , Figure 3This utility model provides a briquetting machine for ferrous metal casting, including a housing 1; characterized in that: a lifting frame block 11 is fixedly connected to the end of the housing 1; a hydraulic rod assembly 12 is rotatably connected to the side wall of the lifting frame block 11; a briquetting frame 13 is rotatably connected to the side wall of the housing 1; the output end of the hydraulic rod assembly 12 is fixedly connected to the briquetting frame 13; a pressing groove 14 is formed on the side wall of the housing 1; a connecting plate 15 is fixedly connected to the side wall of the housing 1; a first motor 16 is fixedly connected to the inner side wall of the connecting plate 15; a threaded rod 17 is provided at the output end of the first motor 16; a sliding block 18 is slidably connected to the side wall of the first motor 16; and the sliding block 18 is slidably connected to the surface of the threaded rod 17; A connecting block 19 is fixedly connected to the side wall of the sliding block 18; a positioning plate 101 is fixedly connected to the side wall of the connecting block 19; a spiral feed hopper 102 is fixedly connected to the side wall of the positioning plate 101; a crushing hopper 103 is fixedly connected to the side wall of the spiral feed hopper 102; a feeding hopper 104 is fixedly connected to the side wall of the crushing hopper 103; a fixing frame 105 is fixedly connected to the inner side wall of the spiral feed hopper 102; a second motor 106 is fixedly connected to the side wall of the fixing frame 105; a spiral conveying rod 107 is provided at the output end of the second motor 106; during operation, the first motor 16 is started, which drives the connecting block 19 to slide forward through the sliding block 18, and drives the spiral feed hopper 102 to slide towards the pressure groove 14 through the positioning plate 101, and... At the middle position above the pressing trough 14, scrap metal is poured into the feed hopper 104 and then conveyed to the pressing trough 14 below via the crushing hopper 103 and the screw feed hopper 102. Because the scrap metal accumulates irregularly in the feed hopper 104, it can cause feed blockage. Before pouring the scrap metal into the feed hopper 104, the second motor 106 is started to drive the screw conveyor 107 to rotate. During the rotation of the screw conveyor 107, its spiral design allows for the uniform conveying of the scrap metal falling into the screw feed hopper 102. Simultaneously, the second motor 106 controls the rotation speed and output of the screw conveyor 107. The angle is adjusted so that when a large amount of scrap metal is poured in, the rotation speed of the screw conveyor 107 is accelerated to increase the conveying speed. When a small amount of scrap metal is poured in, the rotation speed of the screw conveyor 107 is reduced to prevent idling. When the amount of scrap metal accumulated at the pressing trough 14 reaches a certain level, the first motor 16 is restarted to drive the connecting block 19 to move backward for resetting, and the hydraulic rod assembly 12 is activated to push the pressing frame 13 to rotate downward, thereby realizing the pressing operation. This design allows for flexible control by adjusting the screw conveyor according to the amount of material fed in, achieving uniform material conveying, reducing the possibility of blockage in the feed hopper, thereby improving feeding efficiency and production efficiency.

[0029] Furthermore, such as Figure 1 , Figure 4 , Figure 5As shown, the sidewall of the pressing groove 14 is provided with a rubber vibration isolation pad 2; multiple sets of fixed shells 21 are fixedly connected to the sidewall of the rubber vibration isolation pad 2; a first spring assembly 22 is slidably connected to the inner sidewall of the fixed shell 21; a bonding plate 23 is fixedly connected to the end of the first spring assembly 22; a high-strength cast iron platform 24 is provided on the top of the bonding plate 23; the bonding plate 23 and the high-strength cast iron platform 24 are fixedly connected; during operation, in the process of pressing the block, the high-strength cast iron platform 24 set in the upper layer serves as the direct bearing surface of the block, providing stable support for the pressing process, and the fixed shell 21, the first spring assembly 22 and the bonding plate 23 set in the middle layer provide stable support for the pressing process. The spring damping assembly, consisting of three components, transmits vibration energy to the high-strength cast iron platform 24 when the briquetting machine vibrates. The spring damping assembly then converts the kinetic energy of the vibration into the elastic potential energy of the spring, thus providing a buffering effect. Simultaneously, due to the excellent flexibility and vibration isolation performance of the rubber vibration isolation pad 2, the lower layer of rubber vibration isolation pad 2 further absorbs and isolates the vibration, preventing it from propagating to the ground and reducing equipment operating noise. This design, through the vibration-damping composite three-layer base, can buffer, absorb, and isolate the vibration generated by the briquetting machine, thereby achieving vibration absorption and improving equipment stability.

[0030] Furthermore, such as Figure 1 , Figure 6 As shown, the side wall of the pressing frame 13 is provided with a buffer groove 3; multiple sets of piston assemblies 31 are symmetrically fixed to the inner side wall of the buffer groove 3; multiple sets of second spring assemblies 32 are symmetrically fixed to the side wall of the buffer groove 3; a pressing head block 33 is fixed to the end of the second spring assembly 32; the pressing head block 33 is slidably connected to the side wall of the buffer groove 3; during operation, when the pressing frame 13 is pressing the scrap metal, the pressing head block 33, which is in direct contact with the scrap metal, can be buffered and adjusted by the gas buffering effect of the piston assembly 31 and the elastic buffering effect of the second spring assembly 32. This design can improve the fit with irregular material accumulation by setting an adaptive buffer pressing head block, thereby making the pressure evenly transmitted, effectively avoiding molding defects, and significantly improving the density uniformity and overall quality of the pressing block.

[0031] Furthermore, such as Figure 2 As shown, a support block 4 is fixedly connected to the side wall of the connecting block 19; a third motor 41 is fixedly connected to the inner side wall of the support block 4; a blade rod 42 is provided at the output end of the third motor 41; the blade rod 42 is connected through to one side of the crushing hopper 103; during operation, the blade rod 42 is rotated by starting the third motor 41, and the multiple sets of blades on the blade rod 42 can crush the scrap metal poured into the crushing hopper 103. This design can separate larger scrap metal by crushing the poured scrap metal, thereby reducing the situation of larger scrap metal clogging the feed hopper.

[0032] Furthermore, such as Figure 3 As shown, a third spring assembly 5 is symmetrically fixed to the bottom end of the connecting block 19; a lubricating plate 51 is fixed to the end of the third spring assembly 5; the lubricating plate 51 is disposed on the surface of the connecting plate 15; the lubricating plate 51 is slidably connected to the end of the connecting plate 15; during operation, as the connecting block 19 slides, the third spring assembly 5 and the lubricating plate 51 can support both sides of the connecting block 19. Since the surface of the lubricating plate 51 has lubricity, it can improve the smoothness of support when the connecting block 19 moves. This design can improve the stability of the connecting block when it moves through the set support structure.

[0033] Furthermore, such as Figure 6 As shown, a rubber frame 6 is fixedly connected to the side wall of the pressure block frame 13; the rubber frame 6 is fixedly connected to the pressure head block 33; during operation, when the pressure head block 33 is pressed and has a tendency to slide into the buffer groove 3, the rubber frame 6 can provide an elastic buffering effect on the edge of the pressure head block 33. This design can buffer the sliding movement of the pressure head block through the rubber frame, thereby improving stability.

[0034] Furthermore, such as Figure 3 As shown, a support frame 7 is fixedly connected to the bottom end of the connecting plate 15; the support frame 7 is set on a plane; during operation, the support frame 7 can support the connecting plate 15. This design improves the stability of the connecting plate 15 by supporting the connecting plate 15 with the set support frame.

[0035] Working principle: The first motor 16 is started, which drives the connecting block 19 to slide forward through the sliding block 18. This, in turn, drives the screw feed hopper 102 to slide towards the pressing trough 14 via the positioning plate 101, positioning it in the middle of the pressing trough 14. Then, scrap metal is poured into the feed hopper 104 and conveyed to the pressing trough 14 below via the crushing hopper 103 and the screw feed hopper 102. Because the scrap metal accumulates irregularly in the feed hopper 104, it can cause blockages. Before pouring the scrap metal into the feed hopper 104, the second motor 106 is started, driving the screw conveyor 107 to rotate. During the rotation of the screw conveyor 107, the screw conveyor 107's spiral design... The system can uniformly convey scrap metal falling into the screw feed hopper 102. Simultaneously, the second motor 106 controls the rotation speed and output angle of the screw conveyor 107. When a large amount of scrap metal is poured in, the rotation speed of the screw conveyor 107 is accelerated to increase the conveying speed; when a small amount of scrap metal is poured in, the rotation speed of the screw conveyor 107 is reduced to prevent idling. When the accumulated scrap metal at the pressing trough 14 reaches a certain amount, the first motor 16 is restarted to move the connecting block 19 backward for resetting, and the hydraulic rod assembly 12 is activated to push the pressing frame 13 downward, thereby realizing the pressing operation. During the pressing operation, the high-strength cast iron platform 24 set on the upper layer serves as the pressing block... The direct contact surface provides stable support for the briquetting process. The spring damping assembly, composed of the middle-layer fixed shell 21, the first spring assembly 22, and the bonding plate 23, transmits vibration energy to the spring damping assembly through the high-strength cast iron platform 24 when the briquetting machine vibrates. The spring damping assembly then converts the kinetic energy of the vibration into the elastic potential energy of the spring, providing a buffering effect. Simultaneously, due to the good flexibility and vibration isolation performance of the rubber vibration isolation pad 2, the lower-layer rubber vibration isolation pad 2 further absorbs and isolates vibration, preventing its propagation to the ground and thus reducing equipment operating noise. During the briquetting process of the briquetting frame 13 compressing the scrap metal, the gas buffering of the piston assembly 31 and the elasticity of the second spring assembly 32 further contribute to the vibration reduction. The buffering effect can buffer and adjust the pressure head block 33 that is in direct contact with the scrap metal. By starting the third motor 41, the blade rod 42 is driven to rotate. The multiple sets of blades on the blade rod 42 can crush the scrap metal poured into the crushing hopper 103. During the sliding process of the connecting block 19, the third spring assembly 5 and the lubricating plate 51 can support both sides of the connecting block 19. Since the surface of the lubricating plate 51 is lubricated, it can improve the smoothness of the moving support of the connecting block 19. When the pressure head block 33 is squeezed and has a tendency to slide into the buffer groove 3, the rubber frame 6 can provide an elastic buffering effect on the edge of the pressure head block 33. The support frame 7 can provide support for the connecting plate 15.
