Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hardware processing, and particularly relates to a non-standard CNC customized machine table for hardware processing. BACKGROUND

[0002] Hardware processing refers to a process of forming, cutting, connecting and the like of metal materials such as steel, copper and aluminum through various mechanical processing technologies to manufacture parts or products with required shapes, sizes and properties. The non-standard CNC customized machine table refers to a numerical control machining device specially designed and manufactured according to specific processing requirements, product characteristics or production processes. The non-standard CNC customized machine table for hardware processing is a non-standard and customized numerical control machine tool specially designed and manufactured for hardware product processing, and is widely used in mechanical manufacturing and other fields.

[0003] In the prior art patent CN111215504A, a hardware die for sheet metal processing is disclosed, which comprises a lower die seat, a support is installed on the outer side of the lower die seat, a hydraulic rod A is installed on the inner side of the top of the support, an upper die seat is installed at the bottom of the hydraulic rod A, a punch is installed at the bottom of the upper die seat, a die groove is formed in the inner side of the top of the lower die seat, support rods are symmetrically installed on both sides of the lower die seat, a hydraulic rod B is installed on the inner side of the support rod, and a clamping plate is installed at the bottom of the hydraulic rod B. The clamping plate is lowered by the hydraulic rod B to clamp both ends of the sheet metal. The clamping of the clamping plate can keep the sheet metal stable during the stamping process, avoid the deformation of the sheet metal caused by deviation, and thus affect the processing quality. The device is convenient to operate, and the operator can operate it without complicated learning, thereby greatly improving the practicality of the device.

Long-time continuous stamping will cause fatigue damage of the lower die due to repeated impact load, such as notch, which not only leads to the decrease of the processing precision of the CNC machine table, affects the workpiece quality, reduces the product qualification rate, but also leads to the decrease of the service life of the lower die, and reduces the overall production efficiency.

[0031] As shown in ​ 、 ​ 、 ​ 、 ​ 、 ​ 、 ​ 、 ​ 、 ​ 、 ​ and ​ As shown in

[0032] Working principle: when the hardware is processed, the hardware is placed on the lower die 303, and the hydraulic lifting rod 301 is started when stamping, the output end of the hydraulic lifting rod 301 drives the upper die 302 and the lower die 303 to close the mold, so as to realize the stamping processing of the hardware, because the upper die 302 and the lower die 303 are in hard contact when stamping, the upper die 302 will impact the lower die 303, which will cause continuous collision between the upper die 302 and the lower die 303, resulting in damage or fatigue damage phenomenon; When the upper die 302 moves down, the upper die 302 drives the connecting plate 501 to move down, the connecting plate 501 drives the pressing rod 504 to move down, the pressing rod 504 drives the pressing piston 503 to move in the pressing cylinder 502, and the hydraulic oil in the pressing cylinder 502 is extruded. Since the necked tube 602 of the communication pipe 601 is located in the pressing cylinder 502 and the flared tube 603 is located in the lifting cylinder 401, the speed of the hydraulic oil entering the lifting cylinder 401 from the pressing cylinder 502 is small, and the pressing rod 504 moves down with the upper die 302, so that the hydraulic oil generates a reaction force, the pressing piston 503 and the pressing rod 504 generate an upward reaction force, and the effect of the first-stage buffer deceleration of the hydraulic oil is realized; and part of the hydraulic oil is introduced into the lifting cylinder 401 through the necked tube 602, the communication pipe 601 and the flared tube 603, so that the hydraulic oil in the lifting cylinder 401 increases, thereby generating an upward force, forcing the lifting piston ring 402 to move upward, the lifting piston ring 402 drives the lifting rod 403 to move upward, the lifting rod 403 drives the baffle 404 to move upward, the lifting spring 405 generates a stretching effect, the lifting spring 405 generates a reaction force, the lifting spring 405 gradually accumulates energy, the lifting piston ring 402, the lifting rod 403 and the baffle 404 are difficult to move upward, the pressing piston 503, the pressing rod 504 and the connecting plate 501 are difficult to move downward, thereby realizing the second-stage buffer deceleration effect of the lifting spring 405, effectively avoiding the impact of the upper die 302 and the lower die 303 to close the mold, and avoiding the impact and collision between the upper die 302 and the lower die 303 to wear; When the contact block 1101 contacts the contact block 1103, a sudden change in contact force occurs due to the downward movement of the upper die 302, which causes the contact block 1103 to move downward with the contact block 1101, and the hydraulic oil forces the lifting piston ring 402, the lifting rod 403, and the baffle 404 to move upward. The pressure sensing sheet 1102 senses the contact force and transmits the pressure value to the control system. When the pressure value reaches the specified pressure value, the control system obtains information and analyzes the command to control the electromagnetic valve 703 to open, which connects the temporary storage oil cylinder 701 to the lifting oil cylinder 401 through the connecting pipe 601. At this time, the upper die 302 and the lower die 303 are not closed, but are in a state of being about to close. The hydraulic oil forces the lifting piston ring 402, the lifting rod 403, and the baffle 404 to move upward. When the upper die 302 continues to move downward, the upper die 302 drives the pressing rod 504 and the pressing piston 503 to move downward, forcing the pressing piston 503 to continue to press the hydraulic oil. At the same time, the upper die 302 drives the contact block 1101, the contact block 1103, the baffle 404, the lifting rod 403, and the lifting piston ring 402 to move downward, which makes the pressing piston 503 and the lifting piston ring 402 move downward synchronously. The hydraulic oil in the pressing oil cylinder 502 and the lifting oil cylinder 401 enters the temporary storage oil cylinder 701 through the connecting pipe 702, increasing the pressure in the temporary storage oil cylinder 701. Under the guidance of the support plate 801, the pressure piston 803 moves to drive the pushing rod 802 to move forward, and the pushing piston 804 moves forward to push the lubricating oil into the output pipe 1001 through the oil guide pipe 1002. When the upper die 302 and the lower die 303 are closed, the lubricating oil is guided out of the output pipe 1003 to the lower die 303. Through the stamping action between the upper die 302, the hardware, and the lower die 303, the lubricating oil is dispersed around the contact surface of the upper die 302, the hardware, and the lower die 303, achieving the lubrication function and the lubrication effect of the friction between the upper die 302 and the lower die 303, the hardware and the upper die 302, and the lower die 303, thereby further avoiding the wear phenomenon of the upper die 302 and the lower die 303. When the hydraulic lifting rod 301 is reversed, the hydraulic lifting rod 301 moves upward, the lower pressing rod 504 drives the lower pressing piston 503 to move upward, and under the action of the lifting spring 405, the lifting rod 403 drives the lifting piston ring 402 to move downward, so that the lifting piston ring 402 gradually returns to the original state, and the hydraulic oil in the temporary storage cylinder 701 and the lifting cylinder 401 flows back to the lower pressing cylinder 502, the pressure in the temporary storage cylinder 701 decreases, under the guidance of the support plate 801, the pressure piston 803 retreats to drive the pushing rod 802 to retreat, the pushing rod 802 drives the pushing piston 804 to retreat, so that the pushing piston 804 and the temporary storage cylinder 701 generate negative pressure, and through the action of the input pipe 902, the lubricating oil in the storage tank 901 is absorbed into the temporary storage cylinder 701 for temporary storage, preparing for the next time of spraying lubricating oil.

[0033] The present scheme can realize the stamping effect of the hardware, realize the multi-stage buffering effect of the upper die 302 and the lower die 303, realize the low-speed die closing of the upper die 302 and the lower die 303, effectively avoid the impact contact of the upper die 302 and the lower die 303, and avoid the damage to the upper die 302 and the lower die 303; on the other hand, the lubricating effect of the upper die 302, the lower die 303 and the hardware can be realized at the moment of stamping, further reducing the damage to the upper die 302 and the lower die 303 caused by the friction between the upper die 302, the lower die 303 and the hardware, improving the machining precision of the cnc machine, improving the quality of the hardware, improving the product qualification rate, prolonging the service life of the upper die 302 and the lower die 303, and improving the overall production efficiency.

[0034] The above is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
