An aluminum alloy forging servo direct drive screw press

Abstract

The present invention discloses an aluminum alloy forging servo direct-drive screw press, which relates to the technical field of presses and includes an operating table. When the device is working, the screw sleeve rotates relative to the screw, and the bristles inside the lubrication component continuously clean the surface of the screw during the relative rotation of the screw. Since the bristles are connected to the oil-absorbing cotton, the screw is lubricated simultaneously while being cleaned, thereby improving the cleanliness of the screw surface, reducing the friction between the screw sleeve and the screw, and thus reducing the noise generated when the press is working and increasing the service life of the screw. The upper die assembly can synchronously push the piston to move during the downward pressing process, thereby reducing the pressure in the space above the piston and forming a negative pressure state at the leakage port of the upper die seat. Metal debris falling on the upper die seat is sucked into the dust removal box through the leakage port, and due to the effect of the anti-escape net, the debris can be locked in the dust storage box during the upward movement of the piston.

Description

Technical Field

[0001] The present invention relates to the technical field of presses, in particular to an aluminum alloy forging servo direct-drive screw press. Background Art

[0002] The electric screw press is an energy-saving precision forging press. It utilizes a servo motor direct drive, eliminating mechanical transmission, resulting in high transmission efficiency and low failure rates. Its high motor speed and high torque, coupled with digitally controlled energy release, meet various forging process requirements. A touchscreen interface facilitates information exchange between the operator and the machine, allowing for convenient user settings of parameters such as strike energy and fault display. It boasts strong resistance to off-center loads, minimal die stress, long service life, and high forging precision. It surpasses other presses in energy efficiency and precise control of strike force. With no fixed bottom dead center, it prevents machine stalls and can automatically complete the strike cycle, making it suitable for die forging, coining, straightening, bending, and coining processes. It is an ideal forging press for industries such as trains, automobiles, tractors, aviation, hardware tools, medical equipment, and tableware. The electric screw press boasts excellent rigidity, high-precision slide guidance, and strong resistance to off-center loads, making it suitable for multi-station die forging. It is a new type of energy-saving and environmentally friendly press.

[0003] However, when the electric screw press is working, the screw and the slider rotate against each other for a long time. Due to the lack of timely and effective lubrication, the slider makes noise during the lifting process.

In addition, a large amount of debris is easily generated during the metal forging process, which requires manual continuous cleaning to complete the forging process. Manual cleaning in a narrow forging area is prone to safety accidents. Summary of the Invention

When the device is in operation, the screw sleeve rotates relative to the screw, and the bristles inside the lubrication assembly continuously clean the screw surface during the relative rotation of the screw. Because the bristles are connected to the oil-absorbing cotton, they simultaneously lubricate the screw while cleaning it, improving the cleanliness of the screw surface, reducing the friction between the screw sleeve and the screw, thereby reducing the noise generated during the operation of the press and increasing the service life of the screw.

[0018] 2. A servo direct-drive screw press for aluminum alloy forging. The upper die assembly can synchronously push the piston to move during the downward pressing process, thereby reducing the pressure in the space above the piston and forming a negative pressure state at the leakage port of the upper die seat. Metal debris falling on the upper die seat is sucked into the dust removal box through the leakage port, and due to the anti-escape net, the debris can be locked in the dust storage box during the upward movement of the piston, ensuring that the upper die seat is always in a clean state, without the need for manual cleaning, and improving the safety of forging.

The bottom of the limit block 804 is fixedly connected to a pressure block 805, the middle position of the top of the mounting seat 801 is fixedly connected to a screw sleeve 806, the top of the screw sleeve 806 is fixedly provided with a lubrication assembly 807, the lubrication assembly 807 includes an oil storage box 8071, the top of the oil storage box 8071 is provided with an oil storage cavity 8072, and the top of the oil storage box 8071 is fixedly connected to a sealing cover 8073 by bolts, and the interior of the oil storage cavity 8072 is movably provided with an oil-absorbing cotton 807 4. The inner wall of the oil-absorbing cotton 8074 is fixedly connected to a plurality of bristles 8075 in a circular array. One end of each bristle 8075 penetrates the inner wall of the oil storage cavity 8072 and extends to the outside. The lower mold assembly 9 includes a dust collection box 901. A concealed handle 902 is provided in the middle of the front and back of the dust collection box 901. Second slide grooves 903 are provided on both sides of the cavity of the dust collection box 901. A plurality of springs 904 are fixedly connected to the bottom of the cavity of the dust collection box 901.A piston 905 is slidingly provided at the bottom of the dust collection box 901 cavity, and the left and right side walls of the piston 905 are fixedly connected with a top block 906. A dust storage box 907 is fixedly provided above the inner wall of the dust collection box 901 cavity, and the top of the dust storage box 907 is fixedly connected with an anti-escape net 908. The top of the dust collection box 901 is fixedly connected to the upper mold base 909 by bolts. A number of exhaust holes are provided on the back of the operating table 1, and the exhaust holes are connected to the inside of the mounting groove 2. The internal thread of the screw sleeve 806 is adapted to the external thread structure of the screw 6, and the screw sleeve 806 is threadedly sleeved on the outer wall of the screw 6. The limit block 804 and the top of the mounting seat 801 are provided with through holes, and the inside of the through holes are movably provided with The control system 10 includes a control panel 1001. A display screen 1002 is fixedly mounted on the right side of the front of the control panel 1001. A plurality of first and second control buttons 1003 and 1004 are fixedly mounted on the left side of the front of the control panel 1001. The second control buttons 1004 are located above the first control buttons 1003.

[0029] During use, the aluminum alloy block to be forged is first placed on the top of the lower die assembly 9, and then the servo motor 5 is turned on through the control system 10. Since the screw 6 is fixedly connected to the driving end of the servo motor 5, the screw 6 drives the screw sleeve 806 to move downward, and the pressure block 805 gradually approaches the aluminum alloy block and forges it. Then, the control system 10 is used to make the upper die assembly 8 move up and down continuously to realize continuous forging of the aluminum alloy block. Since the top of the top block 906 penetrates the upper die seat 909 and extends to the outside, the pressure block 805 continuously presses the top block 906 during the forging process. Since the top block 906 is fixedly connected to the piston 905, the piston 905 moves downward along the inner wall of the dust collection box 907 cavity. Similar to the working principle of a medical syringe, the air pressure in the space above the dust collection box 907 cavity is reduced, and at the same time, a negative pressure state is formed at the dust leakage port position on the top of the upper die seat 909. The metal debris falling on the upper die seat 909 is sucked in through the dust leakage port, and the metal debris falls out through the passage in the middle position of the anti-escape net 908. The dust box 907 falls into the dust box. Since the cross-section of the anti-escape net 908 is an isosceles trapezoid, that is, a funnel shape, when the top of the top block 906 loses the external force, the spring 904 bounces the piston 905 back to its original position again, and the metal debris inside the dust box 907 is not easy to escape. In addition, since the cross-section of the leakage port on the top of the upper die seat 909 is funnel-shaped, exhaust holes are provided at the same position on the mounting groove 2 and the back of the dust box 901. The two vents are connected, which can ensure the smooth downward movement of the piston 905 and the screw When the sleeve 806 rotates relative to the screw 6, the bristles 8075 inside the lubrication component 807 rotate relative to the screw 6, and the bristles 8075 continuously clean the surface of the screw 6. Since the bristles 8075 are connected to the oil-absorbing cotton 8074, while cleaning the screw 6, the bristles 8075 can absorb lubricating grease from the oil-absorbing cotton 8074 and lubricate it simultaneously, thereby improving the cleanliness of the surface of the screw 6, reducing the friction between the screw sleeve 806 and the screw 6, and thus reducing the noise generated when the press is working.
