Description

Technical Field

[0001] The invention specifically relates to the technical field of aluminum block pressing, and in particular to an aluminum block pressing device with an aluminum block automatic correction function. Background Art

[0002] Aluminum block tablet press is a device used to press aluminum blocks or other metal blocks into thin sheets, round sheets, special-shaped sheets and other forms. This machine is widely used in metal processing, chemical, pharmaceutical, food, electronics, construction, aerospace and other industries. Aluminum block tablet press usually consists of the following main parts: press: the press is the core part of the tablet press, which provides the required pressure to press the aluminum block into the required shape; mold: the mold determines the shape and size of the pressed metal sheet; the mold is usually made of high-strength steel and can be customized to meet different shape requirements; feeding system: the feeding system is responsible for feeding the aluminum block into the pressing area of ​​the press; control system: the control system is used to control the operation of the tablet press, including parameters such as pressure, speed, temperature, etc.; safety device: the safety device ensures safety during operation and prevents accidental injuries; lubrication system: during the pressing process, the lubrication system can reduce friction and wear and improve production efficiency; cooling system: the cooling system is used to control the temperature during the pressing process to ensure the quality of the metal sheet.

[0003] The invention patent with publication number CN113399575A discloses an aluminum block tablet press and a method of using the same, including a base, a first support plate, a second support plate, a stamping assembly, a support platform and a feeding assembly. The second hydraulic cylinder is used for driving so that the pressing head is used to tablet the aluminum block. The pneumatic clamp is used to control the clamp to fix the aluminum block, so as to avoid the aluminum block from running off during the tableting process of the aluminum block tablet press, thereby further improving the tableting accuracy of the aluminum block tablet press and the tableting effect of the aluminum block tablet press. At the same time, the aluminum block is clamped by the clamp to effectively avoid the aluminum block from slipping out, thereby avoiding the aluminum block from flying out and injuring people, thereby further improving the safety of the use of the aluminum block tablet press. The lifting plate is slidably matched on the support rod through the sliding hole, so that the lifting plate can move up and down more stably, thereby further improving the tableting effect of the aluminum block tablet press on the aluminum block.

[0004] The aluminum block sheet press disclosed in the above-mentioned prior art controls the chuck through a pneumatic clamp to fix the aluminum block.

During the descending process of the lifting rod 151, it cooperates with the screw sleeve 152. The screw sleeve 152 drives the lifting rod 151 to rotate, so that the lifting rod 151 controls the rotation of the first gear 153. The first gear 153 controls the rotation of the ring gear 41 and the rotating table 40. An arc-shaped rack 37 is installed on the rotating table 40. The arc-shaped rack 37 is meshed with the second gear 36. During the rotation of the rotating table 40, the second gear 36 is driven to rotate by the arc-shaped rack 37, thereby realizing the rotation of the elastic telescopic rod 32 and the extrusion plate 31.

[0036] In the embodiment of the present application, it should be noted that four through grooves 122 are symmetrically opened on the processing table 12, and correspondingly, four correctors 30 are also provided. The extrusion plates 31 in the four correctors 30 rotate synchronously to synchronously position the four sides of the aluminum block 20 after the extrusion block is separated from the aluminum block 20, so that the aluminum block 20 is directly below the extrusion block.

In the initial state, the air inlet hole 5111 in the arc-shaped adsorption area is connected to the positioning hole 121 in the annular positioning area of ​​the inner circle. When the air outlet 513 draws air outward, the air inside the cavity of the sliding plate 511 and the inside of the fixed cylinder 512 is discharged from the air outlet 513, and a negative pressure is generated inside the positioning hole 121, thereby adsorbing and fixing the aluminum block 20 on the processing table 12. When the sliding plate 511 slides on the fixed cylinder 512, the air inlet hole 5111 in the arc-shaped adsorption area is connected to the positioning hole 121 in the annular positioning area of ​​the outer circle, thereby increasing the adsorption area of ​​the positioning hole 121, so that the positioning hole 121 can adsorb and fix the aluminum block 20 with a reduced thickness and an increased area.

When the extrusion block moves toward the aluminum block 20, the extrusion block contacts and drives the pressure rod 532 to move downward, so that the first piston 533 moves downward to press the air in the lower cavity of the first shell 531 into the right cavity of the second shell 534, thereby driving the second piston 536, the piston rod 537 and the pull plate 538 to move leftward, so that the pull plate 538 controls the movement of the sliding plate 511. It should be noted that the thickness of the aluminum block 20 is continuously reduced during the pressing process. In order to ensure that the extrusion block can contact the aluminum block 20, the downward pressing distance of the extrusion block is increased, so that the downward moving distance of the pressure rod 532 and the first piston 533 is increased, and the amount of air entering the right cavity of the second shell 534 is increased, so that the pulling plate 538 controls the moving distance of the sliding plate 511 to increase, and finally the air inlet hole 5111 in the arc-shaped adsorption area is connected with the positioning hole 121 in the annular positioning area of ​​the outer circle, so that the positioning hole 121 can adsorb and fix the aluminum block 20 with an increased area, thereby preventing the aluminum block 20 from moving during the pressing process.

In the initial state, the ventilation holes 5221 on the fixed plate 522 are staggered with the ventilation holes 5221 on the rotating plate 523, and the positioning hole 121 cannot generate negative pressure. When the lifting plate 15 drives the extrusion block toward When the aluminum block 20 moves, the rotating table 40 rotates, and the rotating table 40 drives the air pump 42 and the exhaust pipe 524 to rotate, so that the exhaust pipe 524 controls the rotating plate 523 to rotate, so that the ventilation holes 5221 on the fixed plate 522 are connected with the ventilation holes 5221 on the rotating plate 523, and the positioning holes 121 generate negative pressure to adsorb and fix the aluminum block 20 when the extrusion block presses the aluminum block 20.
