Description

Technical Field

[0001] The invention relates to the technical field of powder cutting and compression equipment, and in particular to a powder cutting compressor. Background Art

[0002] There are generally two extrusion methods for compressing metal waste in the prior art. The first one is more common, that is, using a pneumatic cylinder or an oil cylinder for extrusion. CN202410682653.6 discloses a metal extrusion device and an extrusion method, which uses a hydraulic cylinder to extrude downward. The metal waste needs to be placed in the silo manually, and the side window is used to feed the material and extrude it from the top downward. The other method is through roller extrusion, such as CN202020324476.1 which discloses an aluminum extruder, which uses a double roller extrusion method.

[0003] The first method generally uses a cylinder or oil cylinder to directly squeeze and push out at one time. Since the cylinder generates power and movement by controlling the in and out of compressed air, this working method has limited effect on hard and rigid metal waste. In the compression process, the metal waste may cause the piston of the cylinder to get stuck, thereby affecting the normal operation of the cylinder. For the direct extrusion method of the oil cylinder, it is also difficult to achieve the ideal compression effect when the oil cylinder is squeezed due to the different characteristics of the shape, size and hardness of the metal waste. In addition, due to the unreasonable structural design of the extrusion device in the prior art, the stress capacity is limited. Generally, a high-power oil cylinder cannot be used for compression, resulting in low compression efficiency, and the volume of the compressed waste block is large, that is, the waste may not be compressed evenly, or the density of the compressed waste is not high enough, which will affect the subsequent processing and recycling. In addition, there will be a certain amount of waste liquid in the metal waste, such as oil, cutting fluid, etc. Incomplete extrusion will increase the weight of the compressed waste, and the cleanliness is low, which is inconvenient to transport or store. At the same time, a large amount of cutting fluid is wasted, which cannot be recycled, and the oil or cutting fluid in the waste is easy to drip onto the ground, causing dirt and other environmental problems. The second roller extrusion method, because metal debris is easy to wrap around the roller, it is easy to get stuck during the rotation of the roller and cause a crash, and there are also problems such as low compression efficiency and low compression density. Summary of the invention

[0004] The present invention aims to overcome at least one defect of the above-mentioned prior art and provide a powder cutting compressor to solve the problems of large storage space occupied by waste materials in existing processing plants and low compression efficiency.

[0005] The present invention provides a powder cutting compressor, comprising a machine base, and a first oil cylinder assembly and a material pressing bin assembly arranged on the machine base; the material pressing bin assembly comprises a material pressing bin main body, a movable cover plate, and a driving assembly, a feeding port is arranged on the top of the material pressing bin main body, a first movable bin door is arranged on one side, and a second movable bin door is arranged on the other side; the interior of the material pressing bin main body is a material pressing chamber; the driving assembly comprises a first driving module and a second driving module; the movable cover plate comprises a first pressing plate and a second pressing plate; one end of the first pressing plate is rotatably connected to one side of the material pressing bin main body, and the other end is rotatably connected to the second pressing plate; the first pressing plate is driven to rotate relative to the material pressing bin main body by the first driving module to realize a primary material pressing of the material pressing chamber; the second pressing plate is then driven to rotate toward the material pressing chamber by the second driving module to realize a secondary material pressing of the material pressing chamber; the first oil cylinder assembly is connected to the first movable bin door, and the first oil cylinder assembly pushes the first movable bin door to compress the material after the secondary material pressing, and pushes the compressed product out of the second movable bin door.

[0006] The main body of the material pressing bin of the present invention is a cavity structure with an opening at the top. When the feed port is open, the first pressing plate and the second pressing plate are on the same horizontal plane. After feeding into the feed port, when the first driving module drives the first pressing plate to rotate 90° relative to the main body of the material pressing bin, the first pressing plate and the second pressing plate cover the feed port to realize the first pressing of the material in the material pressing cavity. At this time, if there is a lot of free space in the material pressing cavity, the first driving module is used to open the first pressing plate. At this time, the feed port is open and secondary feeding can be carried out. On the basis of the present invention, a sensor or a corresponding scale can be set in the material pressing cavity. When the warning line is reached after the material pressing, the material is no longer fed. Then the second driving module is used to drive the second pressing plate to continue to rotate 90° toward the direction of the material pressing cavity to realize the secondary pressing of the material pressing cavity. At this time, the first pressing plate and the second pressing plate are 90°, so that the first pressing plate, the second pressing plate and the inner wall of the main body of the material pressing bin form a closed mold cavity of a rectangular hexahedron. The rotation angles of the primary pressing material and the secondary pressing material in the present invention are not limited to 90 degrees, and simple angle adjustments made on the basis of the secondary pressing material structure of the present invention are within the protection scope of the present invention.

[0007] Compared with the low-power cylinders in the prior art, the first cylinder assembly has greater power and can achieve efficient compression. The first cylinder assembly is connected to the first movable door, and the second movable door is opposite to and symmetrically designed to the first movable door, and the two are on the same axis. After the secondary pressing is completed, the first cylinder assembly is started, and the first cylinder assembly pushes the first movable door to compress the waste material in the pressing chamber after the secondary pressing. After the compression is completed, the waste material forms a metal compression block, and the first cylinder assembly is used to continue to push the metal compression block out of the second movable door.

[0008] The present invention adopts multi-cylinder linkage to quickly form a closed mold cavity, which improves the extrusion efficiency. Multiple feedings can be achieved through the first-level initial pressure. The metal compression block obtained by the final extrusion and pushing has a higher density, which further compresses the space of the finished product and improves the compression efficiency. At the same time, it can reduce the content of residual engine oil or cutting fluid in the metal compression block.

[0009] Furthermore, an oil collecting port is provided at the bottom of the second movable bin door, an oil port plug is provided on the oil collecting port, and an oil collecting tank is provided below the oil collecting port.

[0010] The present invention squeezes out oil or cutting fluid while squeezing waste materials, and the oil or cutting fluid is discharged through the gap between the second movable bin door and the side wall of the material pressing bin body, that is, the oil collecting port. An oil collecting tank is designed below the second movable bin door, and an oil pump can also be provided, which is connected to the oil collecting tank through a pipeline to extract the oil. Therefore, the powder cutting compressor of the present invention solves the environmental protection problems of existing processing plants, such as large storage space occupied by waste materials, large waste of cutting fluid, failure to recycle, and dirt and mess caused by oil or cutting fluid in the waste materials easily dripping onto the ground.

[0011] Furthermore, one or more locking cylinder assemblies are provided on the side of the material pressing bin body where the first movable bin door and the second movable bin door are located.

[0012] When the cylinder push rod of the high-power first cylinder assembly pushes the first movable bin door to extrude materials, the side surfaces of the material pressing bin body where the first movable bin door and the second movable bin door are located will be subjected to corresponding extrusion pressure. Therefore, in order to improve the stress strength, the present invention designs one or more groups of locking cylinder assemblies. When the cylinder push rod of the first cylinder assembly is working, the locking cylinder assembly is started to resist the extruded material to increase the overall stress strength.

[0013] Furthermore, the pressing chamber of the pressing bin body is formed by a bottom plate, a first side plate, a second side plate, a third side plate and a fourth side plate; the first driving module and the second driving module are arranged on the outside of the fourth side plate; the first movable bin door is arranged on the first side plate, and the second movable bin door is symmetrical to the first movable bin door and is arranged on the third side plate; the locking cylinder assembly is arranged on the first side plate and the third side plate.

[0014] Specifically, the locking cylinder assembly includes a first locking cylinder, a second locking cylinder, a third locking cylinder and a fourth locking cylinder; the first side panel is provided with a first movable plate and a second movable plate, and the third side panel is provided with a third movable plate and a fourth movable plate; the first locking cylinder is connected to the first movable plate, and the second locking cylinder is connected to the second movable plate; the third locking cylinder is connected to the third movable plate, and the fourth locking cylinder is connected to the fourth movable plate; the first movable plate is perpendicular to the axis where the second movable plate is located; the third movable plate is perpendicular to the axis where the fourth movable plate is located.

[0015] The present invention designs four groups of locking oil cylinders, one group is designed for the horizontal axis direction and the vertical axis direction of the first side plate and the third side plate, wherein the first locking port is designed above the first movable chamber door, and the second locking port is designed on the side; the third locking port is designed above the second movable chamber door, and the fourth locking port is designed on the side; the first movable plate is installed at the first locking port, the second movable plate is installed at the second locking port; the third movable plate is installed at the third locking port; the fourth movable plate is installed at the fourth locking port. Each movable plate corresponds to a group of locking oil cylinders. When the cylinder push rod of the first oil cylinder assembly pushes the first movable chamber door to compress the material, the first locking oil cylinder, the second locking oil cylinder, the third locking oil cylinder and the fourth locking oil cylinder are synchronously started, and then the first movable plate, the second movable plate, the third movable plate and the fourth movable plate are pushed to synchronously extrude the material, thereby improving the stress strength of the entire closed mold cavity, and during the high-intensity extrusion process of the material, the oil and cutting fluid flow downward to the oil collecting port and are uniformly recovered by the oil collecting tank below the oil collecting port.

[0016] Furthermore, the inner wall of the third side plate is in an arc shape; and the side edge of the free end of the second pressing plate is a beveled edge.

[0017] Since the shape of metal scraps is not fixed and the sizes vary, the square pressing chamber in the prior art has many dead corners, which are prone to jamming and uneven pressing, especially the materials located at the corners cannot be compressed synchronously, which also leads to low compression efficiency. In order to facilitate material concentration, the inner wall of the third side plate of the present invention adopts an arc-shaped structure, that is, the internal corners are rounded, and there are fewer right-angle dead corners during the secondary pressing process. At the same time, the side edge of the free end of the second pressing plate is a beveled edge. During the secondary pressing process, the design of the beveled edge can increase the contact area with the arc-shaped inner wall, so that the beveled edge of the second pressing plate fits more closely with the arc-shaped inner wall, so that the metal chips attached to the inner wall can all be scraped downward into the closed mold cavity. At the same time, the arc-shaped inner wall also facilitates the material to smoothly enter the pressing chamber from the feed port, and the concentration is higher.

[0018] Furthermore, the first driving module and / or the second driving module includes one or more groups of cylinder driving components.

[0019] More preferably, the first drive module includes a second cylinder assembly and a third cylinder assembly, and the second drive module includes a fourth cylinder assembly and a fifth cylinder assembly; the powder cutting compressor also includes a first hinge and a second hinge; one end of the first pressure plate is connected to the rotating end of the first hinge, and the other end is connected to the fixed end of the second hinge; one end of the second pressure plate is connected to the rotating end of the second hinge, and the other end is a free end; one end of the second cylinder assembly and the third cylinder assembly is connected to the machine base, and the other end is connected to the first hinge; one end of the fourth cylinder assembly and the fifth cylinder assembly is connected to the first hinge, and the other end is connected to the second hinge.

[0020] The present invention adopts a method of synchronously pushing multiple cylinders and advancing the material pressing layer by layer with a secondary cylinder. Firstly, it can increase the efficiency of single material pressing. Secondly, it can determine whether to add material according to actual conditions after single material pressing, so as to realize a process of multiple feeding. Compared with the mode of one feeding and one compression in the prior art, the present invention adopts a method of initial compression with a secondary cylinder and finally selects a high-power cylinder for ultimate compression, which improves the compression efficiency, increases the density of the metal compression block, and greatly reduces the volume of the metal compression block. At the same time, it reduces the content of oil and cutting fluid in the metal compression block, and improves the recovery rate of oil and cutting fluid.

[0021] Furthermore, the first hinge member includes a first transmission rod, a first hinge arm, a second hinge arm, a first transmission seat, a second transmission seat and a plurality of first sleeves; the first transmission rod is rotatably connected to the pressure bin body by screws, and the first sleeve is sleeved on both ends and / or the middle of the first transmission rod; one end of the first hinge arm and the second hinge arm is fixed to the first transmission rod by screws, and the other end is respectively connected to the second cylinder assembly and the third cylinder assembly; one end of the first transmission seat and the second transmission seat is sleeved and fixed on the first transmission rod, and the other end is respectively connected to the fourth cylinder assembly and the fifth cylinder assembly, and one end of the first pressure plate is fixed to the side of the first hinge arm and the second hinge arm; the first transmission seat and the second transmission seat are installed between the first hinge arm and the second hinge arm.

[0022] Furthermore, the second hinge member includes a second transmission rod, a third transmission seat, and a second sleeve and a third sleeve; the second sleeve is sleeved on both ends of the second transmission rod; the third transmission seat is sleeved on the middle part of the second transmission rod; one end of the second pressure plate is fixed to the side of the second sleeve and the third transmission seat; the third sleeve is sleeved on the second transmission rod and is located between the third transmission seat and the second sleeve; the other end of the first pressure plate is connected to the side of the third sleeve.

[0023] The present invention adopts the first hinge and the second hinge in combination with the first drive module and the second drive module to realize the secondary drive. In order to make the overall structure more compact, the first hinge and the second hinge of the present invention are respectively arranged at the two ends of the first pressure plate; the two ends of the first transmission rod are rotatably connected with the first side plate and the third side plate by screws; the second cylinder assembly and the third cylinder assembly are synchronously driven; the first hinge arm and the second hinge arm are pushed to drive the first transmission rod to rotate, so as to realize the synchronous rotation of the first pressure plate and the second pressure plate. The transmission principle of the second hinge is similar, and the fourth cylinder assembly and the fifth cylinder assembly of the second drive module synchronously push the third transmission seat to drive the second transmission rod to rotate, thereby realizing the rotation of the second pressure plate driven by the second sleeve. And the secondary extrusion of the present invention is carried out on the basis of the primary extrusion. The fourth cylinder assembly and the fifth cylinder assembly of the present invention are arranged between the second cylinder assembly and the third cylinder assembly, and the overall structure is more compact and the transmission stability is higher.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) The present invention adopts multi-cylinder linkage to quickly form a closed mold cavity, thereby improving the extrusion efficiency. Multiple feeding can be achieved through the first-level initial pressure. The metal compression block obtained by the final compression and pushing has a higher density, which further compresses the space of the finished product and improves the compression efficiency. At the same time, it can reduce the content of residual engine oil or cutting fluid in the metal compression block.

[0026] (2) The present invention utilizes a high-power oil cylinder to compress waste materials while squeezing out oil or cutting fluid, and the oil or cutting fluid is discharged through the gap between the second movable door and the side wall of the material pressing bin body, that is, the oil collecting port. An oil collecting tank is designed below the second movable door, and an oil pump can also be provided, which is connected to the oil collecting tank through a pipeline to extract the oil. Therefore, the powder cutting compressor of the present invention solves the environmental protection problems of existing processing plants, such as large storage space occupied by waste materials, large waste of cutting fluid, failure to recycle, and dirt and mess caused by oil or cutting fluid in the waste materials easily dripping onto the ground.

[0027] (3) The present invention designs one or more locking cylinder assemblies. When the cylinder push rod of the first cylinder assembly is working, the locking cylinder assembly is started to push against the squeezed material to increase the overall stress intensity. And it is precisely because of the improvement of the overall stress intensity that the powder cutting compressor of the present invention can use a large cylinder with a larger power than the cylinder in the prior art or even multiple levels for the final compression molding, so that the density of the compressed material is higher and the occupied volume is smaller. At the same time, the high-power extrusion significantly improves the extrusion efficiency, and can squeeze the waste liquid and waste oil in the waste material more thoroughly, so that the obtained finished product is drier and convenient for subsequent transportation.

[0028] (4) In order to facilitate material concentration, the inner wall of the third side plate of the present invention adopts an arc-shaped structure, that is, the internal corners are rounded, and there are fewer right-angle dead corners during the secondary pressing process. At the same time, the side edge of the free end of the second pressing plate is a beveled edge. During the secondary pressing process, the design of the beveled edge can increase the contact area with the arc-shaped inner wall, so that the beveled edge of the second pressing plate fits more closely with the arc-shaped inner wall, so that all metal chips attached to the inner wall can be scraped downward into the closed mold cavity. At the same time, the arc-shaped inner wall also facilitates the material to smoothly enter the pressing cavity from the feed port, with a higher degree of concentration, further improving the compression efficiency.

The bottom of the second movable bin door 20 is provided with an oil collecting port 30, and the oil collecting port 30 is provided with an oil port plug 40, and an oil collecting box is provided below the oil collecting port 30, which is not shown in the figure.

[0043] The oil or cutting fluid after extrusion of the present invention is discharged through the gap between the second movable bin door 20 and the side wall of the material pressing bin body 31, that is, the oil collecting port 30. An oil collecting tank is designed below the second movable bin door 20, and an oil pump can also be provided to connect the oil collecting tank through a pipeline to extract the oil. Therefore, the powder cutting compressor of the present invention solves the environmental protection problems of the existing processing plant waste occupying a large storage space, the large waste of cutting fluid, the failure to recycle, and the dirt and mess caused by the oil or cutting fluid in the waste easily dripping on the ground.

[0044] like Figures 1-2 As shown, the pressing chamber of the pressing bin body 31 of the present invention is formed by a bottom plate 311, a first side plate 312, a second side plate 313, a third side plate 314 and a fourth side plate 315; the first driving module 34 and the second driving module 35 are arranged on the outer side of the fourth side plate 315; the first movable bin door 10 is arranged on the first side plate 312, and the second movable bin door 20 is symmetrical with the first movable bin door 10 and is arranged on the third side plate 314; it also includes a plurality of locking cylinder assemblies 4, combined with Figure 7 As shown, it specifically includes a first locking cylinder 41, a second locking cylinder 42, a third locking cylinder 43 and a fourth locking cylinder 44; combined Figure 1As shown, the first side plate 312 is provided with a first movable plate 40 and a second movable plate 50, and the third side plate 314 is provided with a third movable plate 60 and a fourth movable plate 70; the first locking oil cylinder 41 is connected to the first movable plate 40, the second locking oil cylinder 42 is connected to the second movable plate 50; the third locking oil cylinder 43 is connected to the third movable plate 60, and the fourth locking oil cylinder 44 is connected to the fourth movable plate 70. When the cylinder push rod of the high-power first oil cylinder assembly 2 pushes the first movable bin door 10 to squeeze the material, the side of the material pressing bin body 31 where the first movable bin door 10 and the second movable bin door 20 are located, that is, the first side plate 312 and the third side plate 314 will be subjected to a large extrusion force, so in order to improve the stress strength, the present invention designs one or more groups of locking oil cylinder assemblies 4, when the cylinder push rod of the first oil cylinder assembly 2 is working, by starting the locking oil cylinder assembly 4, the squeezed material is pressed to increase the overall stress strength.

[0045] The present invention designs four sets of locking cylinders, one set is designed for the horizontal axis direction and the vertical axis direction of the first side plate 312 and the third side plate 314, wherein a first locking opening is designed above the first movable door 10, and a second locking opening is designed on the side; a third locking opening is designed above the second movable door 20, and a fourth locking opening is designed on the side; the first movable panel 40 is installed at the first locking opening, the second movable panel 50 is installed at the second locking opening; the third movable panel 60 is installed at the third locking opening; and the fourth movable panel 70 is installed at the fourth locking opening. Each movable panel corresponds to a set of locking cylinders. When the cylinder push rod of the first cylinder assembly 2 pushes the first movable bin door 10 to compress the material, the first locking cylinder 41, the second locking cylinder 42, the third locking cylinder 43 and the fourth locking cylinder 44 are started synchronously, thereby pushing the first movable plate 40, the second movable plate 50, the third movable plate 60 and the fourth movable plate 70 to synchronously extrude the material, thereby improving the stress strength of the entire closed mold cavity. During the high-intensity extrusion process of the material, the oil and cutting fluid flow downward to the oil collecting port 30 and are uniformly recovered by the oil collecting tank below the oil collecting port 30.

The present invention adopts a method of synchronously pushing multiple cylinders and advancing the material pressing layer by layer with a secondary cylinder. Firstly, it can increase the efficiency of single material pressing. Secondly, it can determine whether to add material according to actual conditions after single material pressing, so as to realize a process of multiple feeding. Compared with the mode of one feeding and one compression in the prior art, the present invention adopts a method of initial compression with a secondary cylinder and finally selects a high-power cylinder for ultimate compression, which improves the compression efficiency, increases the density of the metal compression block, and greatly reduces the volume of the metal compression block.
