Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy technology, specifically to a controllable pressure extrusion composite device for processing high-strength alloy steel. Background Technology

[0002] High-strength alloys refer to metallic materials with excellent properties such as high strength, high wear resistance, and high corrosion resistance. Current processing of high-strength alloys involves pressing metal or other alloy powders into the desired shape and size using specific equipment and techniques. The pressed powder blocks are then sintered to complete the molding process, reducing the difficulty of subsequent processing. For small-scale production, self-made molds are often used in stamping presses. The disadvantages are low automation and the need to disassemble the mold entirely for demolding. For large-scale production, the desired shape is cut into the upper part of the base, and a protrusion with the same shape is connected to the lower side of the upper hydraulic actuator's telescopic end. After pressing, the hydraulic actuator inside the base pushes the material out of the groove. The advantage is high automation, but changing the shape of the protrusion and the groove inside the upper part of the base requires modification when producing a different product, making it cumbersome. Therefore, a controllable pressure extrusion composite device for processing high-strength alloy steel is designed to solve these problems. Utility Model Content

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-4This utility model provides a technical solution: a controllable pressure extrusion composite device for processing high-strength alloy steel, comprising: a base 1, an ejector hydraulic device 2 installed at the upper end of the base 1, connecting plates 3 connected to the front and rear sides of the upper surface of the base 1, an upper housing 4 connected to the upper end of the connecting plates 3, a lower pressure hydraulic device 5 installed in the middle of the upper housing 4, a hydraulic pump, an oil tank, a pressure control valve, a flow control valve, and a directional control valve installed inside both the base 1 and the upper housing 4, the ejector hydraulic device 2 and the lower pressure hydraulic device 5 being connected to the hydraulic pump, oil tank, pressure control valve, flow control valve, and directional control valve via pipelines, a controller 6 installed on the left side of the rear surface of the connecting plate 3, the controller 6 being electrically connected to the hydraulic pump, pressure control valve, flow control valve, and directional control valve, and the lower telescopic end of the lower pressure hydraulic device 5. A lower pressure platform 7 is fixedly connected. Fixed blocks 8 are fixedly connected to the front and rear sides of the upper surface of the base 1. A push block 9 with an inner slope is inserted between the two fixed blocks 8. A triangular notch is provided on the inner side of the end of the push block 9. An extrusion block 10 is placed inside the notch at the end of the push block 9. An outer mold 11 is placed in the middle of the upper surface of the base 1 and between the fixed blocks 8 and the push block 9. The outer mold 11 is hollow inside and open at both the top and bottom. A boss is provided at the lower end of the outer mold 11. A hole is opened in the middle of the upper end of the base 1. The upper telescopic end of the ejector hydraulic device 2 extends into the hole inside the upper end of the base 1. A mold base plate 12 is placed at the lower end of the outer mold 11. The lower end of the mold base plate 12 extends into the hole inside the upper end of the base 1. A lower pressure block 13 is inserted into the upper end of the outer mold 11.

[0024] In use, place the outer mold 11 on the upper surface of the base 1, then place the extrusion block 10 in the groove at the corner of the fixed block 8, and then insert the push block 9 into the gap of the fixed block 8. Afterwards, tap with a copper rod, causing the inclined surfaces of the push block 9 and the extrusion block 10 to press against each other, thus fixing the position of the outer mold 11. Next, place the mold base plate 12 at the bottom of the outer mold 11. Input the required pressure, the stroke of the ejector hydraulic device 2, and the downward pressure hydraulic device 5 outputs onto the controller 6. Place alloy powder inside the outer mold 11, and then grind it smooth with a scraper. After completion, insert the downward pressure block 13 from the top of the outer mold 11. Then operate through the control panel on the upper left surface of the base 1, pressing the buttons on both sides simultaneously with both hands. The controller 6 receives the signal and starts the hydraulic pump, pressure control valve, flow control valve, and directional control valve inside the upper housing 4. The hydraulic pump will draw hydraulic fluid from the oil tank. The output pressure and speed are controlled by the pressure control valve and flow control valve. The output enters the upper input end of the lower pressure hydraulic device 5 through the pipeline, causing the telescopic end of the lower pressure hydraulic device 5 to press down, causing the lower pressure table 7 to move downward and press against the upper end of the lower pressure block 13, thus pressing the alloy powder inside the outer mold 11. After pressing is completed, the ejector hydraulic device 2 is started through the operating table on the upper part of the left surface of the base 1. The telescopic end of the ejector hydraulic device 2 passes through the hole at the upper end of the base 1 and ejects the mold base plate 12 and the lower pressure block 13. After removing the lower pressure block 13, the pressed alloy powder on the mold base plate 12 is removed, and the next pressing can be carried out. When it is necessary to change the product for processing, the push columns on the front and rear sides of the fixing block 8 are tapped to loosen the push block 9. Then, the outer mold 11 and the mold base plate 12 are removed, and the required outer mold 11, mold base plate 12 and lower pressure block 13 are replaced to complete the replacement.

[0025] like Figure 1-3 As shown in the figure, this utility model embodiment provides an implementation method. Based on the above implementation method, an electromagnet is installed inside the upper end of the telescopic end of the ejector hydraulic device 2, and the controller 6 is electrically connected to the electromagnet.

[0026] Analysis of the above structure shows that before the next pressing, the electromagnet inside the telescopic end of the ejector hydraulic device 2 will attract the lower end of the mold base plate 12 and pull it downwards, without needing to press down.

[0027] like Figure 1-3 As shown in the figure, this utility model embodiment provides an implementation method. Based on the above implementation method, a pad 21 is placed on the upper surface of the lower pressing block 13, and the area of ​​the pad 21 is the same as the internal area of ​​the outer mold 11.

[0028] Analysis of the above structure shows that after pressing is completed, the pad 21 and the pressed alloy powder are taken out together for easy removal later.

[0029] like Figure 1-4 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the upper end of the lower pressure block 13 extends outward on both the front and rear sides, and the upper end of the lower pressure block 13 extends beyond the outer side of the outer mold 11.

[0030] Analysis of the above structure shows that when it is necessary to remove the pressure block 13, you can hold the pressure block 13 at the front and back sides extending outwards to make it easy to remove.

[0031] like Figure 1-4 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, a slot 22 is provided at the middle position between the fixing block 8 and the push block 9, and a card block 23 is inserted and connected inside the slot 22.

[0032] Analysis of the above structure shows that after installation, the locking block 23 is placed inside the locking slot 22 to reduce the displacement of the push block 9 during the processing.

[0033] like Figure 1-3 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, safety light curtains 24 are connected to the inner sides of both ends of the two connecting plates 3, and the safety light curtains 24 are electrically connected to the controller 6.

[0034] Analysis of the above structure shows that during the processing, the safety light curtain 24 will detect the position of the opening. If an object extends into the interior of the connecting plate 3, it will send a signal to the controller 6 and initiate an emergency stop command to prevent damage to the equipment or injury to the user.

[0035] like Figure 1-2 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, a storage groove 25 is provided on the left side of the connecting plate 3 on the rear side, and the left side of the controller 6 is rotatably connected to the inside of the storage groove 25.

[0036] Analysis of the above structure shows that when adjusting the data, the controller 6 is rotated towards the opening of the connecting plate 3 to facilitate debugging. After debugging, the controller 6 is rotated into the storage slot 25 to reduce obstacles in the processing.
