Description

Technical Field

[0001] This utility model relates to the field of precision machining technology, specifically to an extrusion press that facilitates the assembly and disassembly of the die head. Background Technology

[0002] An extrusion press is a specialized piece of equipment that uses pressure to shape solid materials through a mold, and it is commonly used in the production of aluminum profiles.

[0003] In the prior art, the patent with publication number CN 220387499 U discloses an automotive aluminum profile extrusion press with a replaceable extrusion head. The device installs and limits the die body by rotating the mounting base until it contacts the base. Then, the mounting base and the base are locked and fixed by bolts. However, the device uses multiple sets of bolts for locking, which need to be installed one by one. When the die body is replaced later, the bolts need to be removed one by one again, which makes the fixing and separation operation of the mounting base and the base quite cumbersome. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an extrusion press that facilitates the assembly and disassembly of the die head. This device uses an elastic plug-in element and inclined extrusion guide to enable the flip-closing part of the die head to automatically flip and lock during the flip-closing process, eliminating the need for subsequent bolt fixation. Furthermore, when disassembling the die head later, the operator only needs to move the slide bar upward and use the inclined extrusion to release the flip-closing locking limit of the flip part, thereby improving the ease of operation for die head assembly and disassembly and effectively solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an extrusion press that facilitates the assembly and disassembly of the die head, including a worktable, two fixed seats are provided in the middle of the upper side of the worktable, a placement seat is provided between the fixed seats, an extrusion shell is provided on the right side of the fixed seat on the right side, and an installation mechanism is also included. The installation mechanism includes a base, a flip cover, a socket, a slot, a self-locking component, and an auxiliary component. The base is located on the upper right side of the workbench. The flip cover is hinged to the upper rear end of the base via symmetrically distributed hinges. A slot is provided on the upper front end of the base. A socket is provided on the lower front end of the flip cover. The socket is inserted into the slot. A self-locking component is provided between the socket and the base. An auxiliary component is provided between the self-locking component and the base. The right end of the extrusion shell is connected to the left end of the base. A die head is engaged between the base and the flip cover.

[0006] Furthermore, it also includes a PLC controller, which is located outside the workbench. The input terminal of the PLC controller is electrically connected to an external power supply, which facilitates the control of the electrical components inside the device.

[0007] Furthermore, the self-locking component includes a groove, a locking block, a slot, an annular seat, a telescopic column, and a spring. The grooves are symmetrically opened laterally on the front side of the base, and the locking blocks are slidably connected inside the grooves. The front side of the socket has symmetrically distributed slots laterally. The end of the locking block near the lateral center of the socket is inserted into the adjacent slot. The end of the locking block away from the lateral center of the socket and the inside of the slot are provided with an annular seat. A telescopic column and a spring are provided between two adjacent annular seats. The springs are movably sleeved with the outer end of the adjacent telescopic column. Through elastic insertion, the flip-top cover inside the extruder, which is convenient for die head disassembly and assembly, is self-locked for flipping and closing.

[0008] Furthermore, the auxiliary components include connecting columns, fixing rods, sliding rods, and arc-shaped brackets. The connecting columns are respectively disposed on the front side of the block, and the base is provided with a fixing rod on the front side. A sliding rod is slidably connected in a rectangular groove in the middle of the fixing rod. Arc-shaped brackets are provided on both the left and right sides of the sliding rod through connecting rods. The arc-shaped brackets are installed in cooperation with the adjacent connecting columns to limit the movement of the block after the die head of the extruder is fixed.

[0009] Furthermore, the auxiliary component also includes a material ejector seat, which is respectively set on the left and right sides of the slide rod via connecting rod two. The material ejector seats are installed in conjunction with adjacent connecting columns. Through inclined extrusion guidance, the card block and card slot in the extruder, which facilitates the disassembly and assembly of the die head, can be inserted and separated by itself.

[0010] Furthermore, the installation mechanism also includes a latching groove, which is located on the right side of the flip cover, facilitating manual operation of the flip cover inside the extruder for easy die head assembly and disassembly by the operator.

[0011] Furthermore, a second fixed base is provided on the upper left side of the worktable, and an electro-hydraulic actuator is provided on the left side of the second fixed base. The input end of the electro-hydraulic actuator is electrically connected to the output end of the PLC controller. The telescopic end of the electro-hydraulic actuator is provided with an extrusion head. A laser sensor is provided on the right side of the second fixed base. The laser sensor is bidirectionally electrically connected to the PLC controller to provide power for the extrusion forming inside the extruder, which facilitates the disassembly and assembly of the die head.

[0012] Compared with the prior art, the beneficial effects of this utility model are: When using an extruder with a convenient die head assembly and disassembly, the flexible plug-in element and the inclined extrusion guide enable the die head's flip-closing part to automatically flip and lock during the flip-closing process, eliminating the need for subsequent bolt fixation. When disassembling the die head later, the operator only needs to move the slide bar upwards and use the inclined extrusion to release the locking limit of the flip-closing part, thereby improving the ease of operation for die head assembly and disassembly.

An electro-hydraulic push rod 9 is provided on the left side of the fixed seat 8. The input end of the electro-hydraulic push rod 9 is electrically connected to the output end of the PLC controller 2. An extrusion head 10 is provided at the telescopic end of the electro-hydraulic push rod 9. A laser sensor 11 is provided on the right side of the fixed seat 8. The laser sensor 11 is bidirectionally electrically connected to the PLC controller 2.

[0017] The system also includes an installation mechanism 6. The installation mechanism 6 includes a base 61, a flip cover 62, a socket 63, a slot 64, a self-locking component 65, and an auxiliary component 66. The base 61 is located on the upper right side of the workbench 1. The flip cover 62 is hinged to the upper rear end of the base 61 by symmetrically distributed hinges. The slot 64 is provided on the upper front end of the base 61. The socket 63 is provided on the lower front end of the flip cover 62. The socket 63 is inserted into the slot 64. The self-locking component 65 is provided between the socket 63 and the base 61. The auxiliary component 66 is provided between the self-locking component 65 and the base 61. The right end of the extrusion shell 5 is connected to the left end of the base 61. The die head 7 is snapped between the base 61 and the flip cover 62.

[0018] The self-locking component 65 includes a groove 651, a locking block 652, a slot 653, an annular seat 654, a telescopic post 655, and a spring 656. The groove 651 is symmetrically opened laterally on the front side of the base 61. The locking block 652 is slidably connected inside the groove 651. The slot 653 is symmetrically distributed laterally on the front side of the socket 63. The end of the locking block 652 near the horizontal center of the socket 63 is inserted into the adjacent slot 653. The end of the locking block 652 away from the horizontal center of the socket 63 and the inside of the slot 653 are provided with an annular seat 654. A telescopic post 655 and a spring 656 are provided between two adjacent annular seats 654. The spring 656 is movably sleeved with the outer end of the adjacent telescopic post 655.

[0019] The auxiliary component 66 includes connecting posts 661, fixing rods 662, sliding rods 663, and arc-shaped brackets 664. The connecting posts 661 are respectively located on the front side of the bracket 652. The base 61 has a fixing rod 662 on its front side. A sliding rod 663 is slidably connected to a rectangular groove in the middle of the fixing rod 662. Arc-shaped brackets 664 are located on both sides of the sliding rod 663 via connecting rods. Each arc-shaped bracket 664 is installed in conjunction with an adjacent connecting post 661. The auxiliary component 66 also... The device includes a material ejector seat 665, which is respectively set on the left and right sides of the slide rod 663 via a connecting rod 2. Each material ejector seat 665 is installed in conjunction with the adjacent connecting post 661. The installation mechanism 6 also includes a latching groove 67, which is opened on the right side of the flip cover 62. During the use of the device, when the locking block 652 is not inserted into the corresponding latching groove 653, the compression force of the spring 656 causes the connecting post 661 to press against the upper side of the adjacent material ejector seat 665.

[0020] The working principle of this utility model is as follows: During the use of the device, when the card block 652 is not inserted into the corresponding card slot 653, the compression force of the spring 656 causes the connecting post 661 to press against the upper side of the adjacent ejector seat 665. When installing the mold head 7, it is inserted into the inner cavity of the base 61. Then, the operator moves the flip cover 62 forward around the hinge axis through the latch 67 to close it. When the flip cover 62 flips forward to a certain extent, the socket 63 of the flip cover 62 rotates into the slot 64. As the socket 63 goes deeper into the slot 64, the bottom edge of the socket 63 presses against the inclined surface of the corresponding locking block 652. The locking block 652 is pressed into the corresponding groove 651, thereby avoiding the rotational insertion of the socket 63 into the slot 64. The telescopic end of the telescopic column 655 and the spring 656 retract. When the flip cover 62 flips to the point where its bottom contacts the upper surface of the base 61, the mold head 7 is installed and fixed. At this time, the socket 63 is fully inserted. Inside the slot 64, the locking block 652 is horizontally aligned with the adjacent slot 653. Then, the compression and reset force of the spring 656 causes the locking block 652 to automatically engage with the corresponding slot 653, thereby automatically limiting the flipping and closing of the flip cover 62. At the same time, when the locking block 652 is fully inserted into the corresponding slot 653 by the compression and reset force of the spring 656, the connecting post 661 on the locking block 652 is vertically aligned with the adjacent arc-shaped card seat 664. Then, the operator pulls down the slide rod 663 to move it vertically downward along the rectangular groove. During the downward movement of the slide rod 663, the arc-shaped card seat 664 is vertically engaged with the corresponding connecting post 661, thereby locking the engagement of the locking block 652 and the slot 653 again to prevent slippage. When disassembling the mold head 7 later, the worker holds the slide rod 663 and slides it vertically upward along the rectangular groove on the fixed rod 662. During the vertical upward sliding process, the slide rod 663 drives the arc-shaped card seat 664 to vertically separate from the corresponding connecting post 661, thereby releasing the lateral movement limit of the card block 652. As the slide rod 663 continues to move upward, the slide rod 663 drives the ejector seat 665, so that the inclined surface of the ejector seat 665 presses against the vertically adjacent connecting post 661. Through the pressure of the inclined surface, the connecting post 661 drives the corresponding card block 652 to automatically slide into the corresponding groove 651, thereby releasing the insertion limit of the card block 652 and the slot 653. Then, the worker flips the flip cover 62 upward by using the buckle 67 to open it, and the mold head 7 can be disassembled and assembled. When extruding aluminum using an extruder, the heated cylindrical aluminum ingot is first placed in the placement seat 4 by an external feeding device. Then, the PLC controller 2 starts the electro-hydraulic push rod 9 so that its extension end drives the extrusion head 10 to move horizontally to the right. During the rightward movement of the extrusion head 10, it contacts the cylindrical aluminum ingot in the placement seat 4, thereby pushing the cylindrical aluminum ingot into the extrusion shell 5. At this time, the outer side of the extrusion head 10 continues to move to the right along the inner wall of the extrusion shell 5. By extruding the cylindrical aluminum ingot in the extrusion shell 5, the aluminum material is extruded in a certain shape through the die head 7. Simultaneously, during this process, the PLC controller 2 activates the laser sensor 11, which emits a light signal to illuminate the right side of the extrusion head 10 and reflects it back to the initial position. Based on the propagation time and speed of the light signal, the horizontal movement distance of the extrusion head 10 is obtained, and the detection result is transmitted to the PLC controller 2 in the form of an electrical signal. The PLC controller 2 adjusts the extension distance of the extension end of the electro-hydraulic push rod 9 according to the detection result. During the use of the device, when the extrusion head 10 moves into the placement seat 4, the lower outer end of the extrusion head 10 slides into contact with the inner arc surface of the placement seat 4. When the extrusion head 10 moves into the extrusion shell 5, the outer side of the extrusion head 10 slides into contact with the inner wall of the extrusion shell 5. Through the sliding connection, the radial pressure applied by the extrusion head 10 to the telescopic end of the electro-hydraulic push rod 9 is borne, thereby preventing the telescopic end of the electro-hydraulic push rod 9 from being damaged due to bearing the radial pressure of the extrusion head 10. After the device has been used for a period of time, the annular seat 654 and its connecting elements should be removed from their respective mounting positions and replaced (the annular seat 654 is fixed to the corresponding position inside the device with screws) to prevent the spring 656 from aging.

[0021] It is worth noting that the PLC controller 2 disclosed in the above embodiments can be MCS-51, the electro-hydraulic actuator 9 can be DYTZB1000-500, and the laser sensor 11 can be a WH-LRF laser rangefinder. The PLC controller 2 controls the operation of the electro-hydraulic actuator 9 and the laser sensor 11 using methods commonly used in the prior art.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
