Abstract
Description
Technical Field
[0001] This application relates to the field of steel chip pressing technology, and in particular to a steel chip pressing device. Background Technology
[0002] As is well known, steel chips mainly originate from metal processing processes such as turning, milling, drilling, and grinding. These processes generate a large amount of steel chips, which usually exist in the form of fine, curled or powdery shapes. Steel chip briquetting machines use cold pressing technology to compress the steel chips generated during metal processing into high-density briquetting structures, making their structure compact and improving the efficiency of steel chip transport.
[0003] Traditional steel chip patty machines consist of a hydraulic cylinder and a cylinder bore. A piston is fitted inside the cylinder bore and fixed to the end of the piston rod in the hydraulic cylinder. The hydraulic cylinder moves the piston, which pushes the steel chips into the cylinder bore. After repeated pushing by the piston, the metal chips are compressed into a steel chip patty at the end of the cylinder bore. However, after prolonged use, the cylinder bore of the steel chip patty machine cracks or deforms due to frequent pressure, requiring replacement of the entire cylinder bore. This is extremely inconvenient, time-consuming, and labor-intensive. This technical problem urgently needs to be solved. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the above-mentioned technology and provide a steel chip pressing device.
[0005] Therefore, this utility model provides a steel chip pressing device, which includes a frame, a first oil cylinder, and a cylinder bore. A piston is sleeved inside the cylinder bore and connected to the piston rod of the first oil cylinder. The cylinder bore has a feed port. The steel chip pressing device also includes a mold and a second oil cylinder. The mold includes a fixed mold and a movable mold.
[0006] The fixed mold has a first channel and a second channel. The first channel is a through hole structure. The first channel and the second channel are connected in a T-shaped structure. The fixed mold is detachably connected to the cylinder bore through the second channel.
[0007] The movable mold is equipped with a third channel, which is a through-hole structure; the movable mold is connected to the piston rod of the second oil cylinder.
[0008] As the piston rod of the second cylinder extends or retracts, the movable mold enters or extends out of the fixed mold through the first channel. When the movable mold enters the fixed mold, the movable mold closes both ports of the first channel, and one port of the third channel is closed by the fixed mold, while the other port of the third channel is connected to the second channel. When the movable mold extends out of the fixed mold, the third channel is exposed to the fixed mold.
[0009] Preferably, the steel chip pressing device is further equipped with a third hydraulic cylinder and a push plate. The piston rod of the third hydraulic cylinder is connected to the push plate. When the third channel exposes the fixed mold, the push plate is positioned opposite one of the ports of the third channel, and the push plate is used to push the steel chip cake out of the third channel.
[0010] Preferably, the steel chip pressing device is also equipped with a receiving tray, which is located below the third channel when the fixed mold is exposed in the third channel.
[0011] Preferably, the cylinder bodies of the first, second, and third hydraulic cylinders are respectively mounted on the machine frame.
[0012] Preferably, the steel scrap pressing device is also equipped with a screw conveyor with a feed hopper, and the discharge port of the screw conveyor is connected to the feed port of the cylinder bore.
[0013] Preferably, the steel chip pressing device is also equipped with casters with locking structures and a chassis. The casters are installed at the bottom of the chassis, and a frame is installed on the chassis.
[0014] Preferably, the fixed mold is detachably connected to the frame via a connecting plate.
[0015] Preferably, the fixed mold and the cylinder bore are detachably connected by a flange seal, and the movable mold is detachably connected to the piston rod of the second oil cylinder.
[0016] The beneficial effects of this utility model are as follows: This utility model provides a steel chip pressing device, which is equipped with a fixed mold and a movable mold. Under the extension or contraction of the piston rod of the second oil cylinder, the movable mold enters or extends from the fixed mold through the first channel. When the movable mold enters the fixed mold, it closes both ports of the first channel, and one port of the third channel is closed by the fixed mold. The other port of the third channel is connected to the second channel. The first oil cylinder compresses the loose steel chips into a steel chip cake in the third channel through the piston. When the movable mold extends from the fixed mold, the third channel is exposed, separating the third channel from the steel chip cake, thus completing the entire compression and forming process of the steel chip cake. Since the fixed mold is detachably connected to the cylinder bore and the movable mold is detachably connected to the piston rod of the second oil cylinder, when the fixed mold or the movable mold cracks or deforms due to frequent pressure after long-term use of the steel chip pressing device, only the connection between the fixed mold and the cylinder bore, or the connection between the movable mold and the piston rod of the second oil cylinder, needs to be disassembled. The fixed mold or the movable mold can then be replaced and installed. The entire replacement and installation process is convenient, quick, and saves time and effort. Attached Figure Description

[0022] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit the scope of this application. Unless otherwise specified, the methods used in this utility model are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.
[0023] Depend on Figures 1-4 As shown, this utility model provides a steel chip pressing device, which includes a frame 11, a first oil cylinder 1, and a cylinder bore 2. A piston 3 is sleeved inside the cylinder bore 2, and the piston 3 is connected to the piston rod of the first oil cylinder 1. The cylinder bore 2 has a feed inlet 21. The steel chip pressing device also includes a mold and a second oil cylinder 4. The mold includes a fixed mold 5 and a movable mold 6.
[0024] The fixed mold 5 is provided with a first channel 51 and a second channel 52. The first channel 51 is a through hole structure. The first channel 51 and the second channel 52 are connected in a T-shaped structure. The fixed mold 5 is detachably connected to the cylinder hole 2 through the second channel 52.
[0025] The movable mold 6 is provided with a third channel 61, which is a through hole structure; the movable mold 6 is detachably connected to the piston rod of the second oil cylinder 4.
[0026] As the piston rod of the second cylinder 4 extends or retracts, the movable mold 6 enters or extends out of the fixed mold 5 through the first channel 51. When the movable mold 6 enters the fixed mold 5, the movable mold 6 closes both ports of the first channel 51, and one port of the third channel 61 is closed by the fixed mold 5. The other port of the third channel 61 is connected to the second channel 52. When the movable mold 6 extends out of the fixed mold 5, the third channel 61 is exposed to the fixed mold 5.
[0027] The working process of this utility model is as follows: This utility model provides a steel chip pressing device. In use, an appropriate amount of steel chips is added into the cylinder hole 2 through the feed port 21. The first oil cylinder 1 is started, and the first oil cylinder 1 compresses the loose steel chips into a steel chip cake 17 in the third channel 61 through the piston 3. Figure 4 (As shown). Then, the piston rod of the first cylinder 1 retracts slightly, causing the piston 3 to disengage from the steel chip cake 17. Then, the second cylinder 4 is activated, and the piston rod of the second cylinder 4 pushes the movable mold 6 out of the fixed mold 5, that is, the third channel 61 exposes the fixed mold 5 (by...). Figure 5 As shown), conventional methods such as pushing with a metal rod are used to remove the steel scrap cake 17 from the third channel 61, separating the steel scrap cake 17 from the other steel scrap cake 17, thus completing the compression molding process of the steel scrap cake 17. Finally, the second hydraulic cylinder 4 is activated to return the movable mold 6 to the fixed mold 5 (by...). Figure 7 , Figure 8 As shown), this prepares for the next compression molding of the steel scrap cake 17.
[0028] Since the fixed mold 5 is detachably connected to the cylinder bore 2 and the movable mold 6 is detachably connected to the piston rod 3 of the second oil cylinder 4, when the steel chip pressing device cracks or deforms due to frequent pressure after long-term use, it is only necessary to disassemble the fixed mold 5 from the cylinder bore 2 or the movable mold 6 from the piston rod 3 of the second oil cylinder 4 and replace it with a new fixed mold 5 or movable mold 6. The whole replacement and installation process is convenient, quick and easy, saving time and effort.
[0029] In some embodiments, by Figures 5-8 As shown, the steel scrap patter device also includes a third hydraulic cylinder 8 and a push plate 9. The piston rod of the third hydraulic cylinder 8 is connected to the push plate 9. When the fixed mold 5 is exposed in the third channel 61, the push plate 9 is positioned opposite one of the ports of the third channel 61. Activating the third hydraulic cylinder 8 extends its piston rod, pushing the steel scrap patter 17 out of the third channel 61 via the push plate 9, thus separating the steel scrap patter 17 from the other steel scrap patter 17 and completing the compression forming process of the steel scrap patter 17. Finally, activating the third hydraulic cylinder 8 retracts its piston rod back to its original position (by...). Figure 6 (As shown); then activate the second hydraulic cylinder 4 to return the movable mold 6 to the fixed mold 5 (by... Figure 7 , Figure 8 As shown), this prepares for the next compression molding of the steel scrap cake 17.
[0030] In some embodiments, by Figure 5 , Figure 6 As shown, the steel chip pressing device is also equipped with a receiving tray 10. When the third channel 61 exposes the fixed mold 5, the receiving tray 10 is set below the third channel 61. The third oil cylinder 8 extends the piston rod and pushes the steel chip cake 17 out of the third channel 61 through the push plate 9. Under the action of gravity, it falls into the receiving tray 10. The receiving tray 10 is used to store the steel chip cake 17.
[0031] In some embodiments, by Figure 1 As shown, the cylinder bodies of the first cylinder 1, the second cylinder 4, and the third cylinder 8 are respectively mounted on the frame 11, making the installation more secure and stable.
[0032] In some embodiments, by Figure 1 As shown, the steel chip pressing device is also equipped with a screw conveyor 13 with a feed hopper 12. The discharge port of the screw conveyor 13 is connected to the feed port 21 of the cylinder bore 2. When in use, the screw conveyor 13 is started, and the screw in the screw conveyor 13 transports the steel chips in the feed hopper 12 to the cylinder bore 2, making the feeding of steel chips more convenient and faster.
[0033] In some embodiments, by Figure 1 As shown, the steel chip pressing device is also equipped with casters 14 with locking structures and a chassis 15. The casters 14 are installed at the bottom of the chassis 15, and a frame 11 is installed on the chassis 15. In use, it is convenient to transport and push the steel chip pressing device to the designated working position.
[0034] In some embodiments, by Figure 1 As shown, the fixed mold 5 is detachably connected to the frame 11 via the connecting plate 16. The detachable connection can be achieved through conventional methods such as bolts, which further improves the stability of the fixed mold 5.
[0035] In some embodiments, by Figure 1 , Figure 4 As shown, the fixed mold 5 and the cylinder bore 2 are detachably connected and sealed by flange 7; the movable mold 6 and the piston rod of the second oil cylinder 4 are detachably connected by bolts. When the steel chip pressing device needs to be replaced with a new fixed mold 5 or a new movable mold 6, it is only necessary to remove the flange 7 between the fixed mold 5 and the cylinder bore 2 to replace the mold, or to remove the bolts between the movable mold 6 and the piston rod of the second oil cylinder 4 to replace the mold. The whole replacement process is convenient, quick, and saves time and effort.
[0036] It should be noted that:
[0037] The first hydraulic cylinder 1, the second hydraulic cylinder 4, and the third hydraulic cylinder 8 of this utility model can also be replaced by other linear reciprocating devices such as electric cylinders and pneumatic cylinders, all of which are within the protection scope.
[0038] In addition, when it is necessary to prepare steel chip patties of new specifications, such as when the height of the steel chip patties remains the same but the bottom area is increased or decreased, the operator can, depending on the actual situation, simply disassemble the fixed mold 5 from the cylinder bore 2, or disassemble the movable mold 6 from the piston rod 3 of the second oil cylinder 4, and replace and install the new fixed mold 5 or movable mold 6 (the fixed mold 5 or movable mold 6 are matched, and the shape or size of the third channel 61 in the inner cavity of the movable mold 6 changes). The entire replacement and installation process is convenient, quick, and saves time and effort.
