Description

Technical Field

[0001] The invention belongs to the technical field of presses, and in particular relates to an anti-deformation press for aluminum pots. Background Art

[0002] The following process is typically used in the manufacturing of aluminum pots: a round aluminum sheet is first stretched into a pot body with a certain depth using a stretching machine, followed by polishing, and finally a pressing operation. Existing processes place the pressing process after polishing, primarily to avoid surface bumps or depressions caused by pressing that would affect the polishing effect. However, during the actual pressing process, when the press applies pressure to the bottom of the pot, the pot often deforms irregularly, seriously affecting the product's dimensional accuracy and appearance quality.

[0003] Traditional presses have significant drawbacks when performing press operations: due to the lack of an effective support structure and a well-formed press structure, the pot body is unevenly stressed during the press process, resulting in deformation and a decrease in product quality. To address this technical challenge, the present invention proposes an anti-deformation press for aluminum pots. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an aluminum pot anti-deformation press that can overcome the above problems or at least partially solve the above problems.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: an anti-deformation press for aluminum pots, including a connecting plate that is lifted and lowered on the press, and also including: a mounting cylinder connected to the connecting plate, and a plurality of pressing dies are connected to the circumference of the bottom surface of the mounting cylinder; a positioning die, which is arranged on the press below the connecting plate to limit the pot body; a plurality of concave modules circumferentially arranged on the positioning die, and a pressing groove is provided on the concave module; during pressing, the pressing die on the mounting cylinder performs a pre-pressing stroke of 70%-85% on the pot body, and then drives the plurality of pressing dies to complete the remaining 15%-30% of the pressing stroke in a stepped manner.

[0006] Preferably, an installation cavity is provided in the installation cylinder, and a plurality of sliding grooves are provided on the circumference of the bottom surface of the installation cylinder. The pressing mold slides in the sliding grooves, and the pressing mold is connected to the bottom wall of the installation cylinder through a spring. A motor is installed in the installation cavity, and a connecting disk is installed on the output end of the motor. The upper surface of the pressing mold is in contact with the connecting disk. A protrusion is fixedly connected to the bottom surface of the connecting disk, and the protrusion corresponds to the pressing mold.

[0007] Furthermore, a plurality of mounting grooves are provided on the circumference of the positioning mold, the concave module is slidably connected in the mounting groove, the upper bottom of the concave module is connected to the bottom wall of the mounting groove through spring 2, and a limiting block is fixedly connected to the side wall of the mounting groove.

[0008] Furthermore, a plurality of connecting arms are installed on the circumference of the mounting cylinder, and the connecting arms are connected to pressure wheels via springs, and the pressure wheels are used to press the outer circumference of the pot body.

[0009] Furthermore, the ends of the two symmetrical connecting arms are slidably connected with an insertion rod through a spring, and a driving rod is installed on the mounting tube. The driving rod is connected to the two symmetrical connecting arms to control the lifting and lowering of the connecting arms.

[0010] Furthermore, a cylinder is installed on the two connecting arms connected to the insertion rod, and the telescopic end of the cylinder is connected to the insertion rod.

[0011] Furthermore, a chamber is provided in the mounting tube, and a piston rod with a piston at one end is installed at the top end of the two connecting arms connected to the insertion rod. The piston rod is slidably connected in the chamber. An annular pipe is installed in the mounting tube, and a plurality of nozzles are provided on the annular pipe respectively facing the pressing mold. The annular pipe is connected to the chamber through a one-way valve.

[0012] Furthermore, a honeycomb protrusion block is provided on the top surface of the positioning mold.

[0013] Furthermore, oil injection pipes are provided on both side walls of the concave module, and the oil injection pipes face the honeycomb protrusion blocks.

[0014] A method for using an aluminum pot anti-deformation press comprises the following steps:

[0015] S1. Place the pot body upside down on the positioning mold and drive the installation cylinder down to approach the positioning mold;

[0016] S2, the pressing die presses the pot body synchronously to 70%-85% of the stroke to eliminate the residual stress of the material, and the honeycomb protrusion block 6 pre-presses a pit on the bottom of the pot;

[0017] S3, the motor drives the connecting plate to rotate, and the protrusion pushes the pressing die at intervals to complete the pressing of the remaining 15%-30% of the stroke;

[0018] S4. The rod moves downward and extends to the mouth of the pot body, and the installation tube moves upward to drive the pot body to be demoulded.

[0019] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: the present invention performs a pre-pressing stage (70%-85% of the stroke) through a press machine and simultaneously presses down through a forming die, so that the material at the bottom of the pot body completes uniform plastic flow, eliminates tensile residual stress, and provides geometric stability for subsequent precision pressing, and then performs a step-by-step precision pressing stage (the remaining 15%-30% of the stroke), and drives the protrusions through a motor to push the forming die one by one, sequentially loading at intervals of 0.5-1 seconds to disperse stress peaks, and uses a spring-elastic compensation to correct local micro-deformations, thereby preventing the pot body from deformation.

[0020] When the installation cylinder is pressed down, the four sets of connecting arms drive the pressure wheels to fit tightly against the outer periphery of the pot body, exerting centripetal force to suppress the eccentric displacement of the pot body during the pressing process; secondly, after the pressing is completed, the rod is inserted into the edge of the pot mouth of the pot body to demold the pot body separately, avoiding the warping of the pot body edge caused by traditional prying demolding.

[0021] When the connecting arm is raised or lowered, the piston rod pumps the lubricant into the annular pipe, which is then atomized and sprayed onto the surface of the pressing die through the nozzle, thereby reducing the friction coefficient and improving the pressing quality of the pot body.

[0022] When the concave module is pressed down, the lubricant is squeezed out and sprayed to the honeycomb protrusion block through the oil spray pipe, forming a boundary lubrication film to prevent the pot body from adhering to the positioning mold. At the same time, the dual-path lubrication design can simultaneously reduce friction and temperature rise, extending the life of the pressing mold and concave module.

[0023] During the pre-stressing stage, the honeycomb protrusions penetrate into the bottom of the pot to form hexagonal pits, which are equivalent to constructing a micro-truss structure, thereby improving the bending stiffness of the pot body and further preventing deformation.

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0036] Example 1: Reference Figures 1-9A press machine for preventing deformation of aluminum pots includes a connecting plate 11 which is arranged on a press machine 1 for lifting. The press machine 1 is equipped with a hydraulic drive system for controlling the lifting of the connecting plate 11. The connecting plate 11 is slidably connected to four guide pillars on the press machine 1 to improve the sliding stability of the connecting plate 11. The press machine 1 also includes: a mounting cylinder 2 connected to the connecting plate 11, a plurality of press molds 24 are connected to the bottom circumference of the mounting cylinder 2, and the mounting cylinder 2 is fixedly connected to the bottom of the connecting plate 11 by bolts; a positioning mold 3 is arranged on the press machine 1 below the connecting plate 11. The force machine 1 is used to limit the pot body 4. An exhaust channel 36 is provided in the positioning mold 3. Both ends of the exhaust channel 36 pass through the positioning mold 3 to exhaust when the pot body 4 is upside down on the positioning mold 3 to avoid a large pressure difference between the inside and the outside. A plurality of concave modules 32 are circumferentially arranged on the positioning mold 3, and a pressing groove 35 is provided on the concave module 32. During pressing, the pressing mold 24 on the mounting cylinder 2 performs a pre-pressing stroke of 70%-85% on the pot body 4, and then drives the plurality of pressing molds 24 to complete the remaining 15%-30% of the pressing stroke in a step-like manner.

[0037] An installation cavity 21 is provided in the installation cylinder 2, and a plurality of slide grooves 243 are provided on the circumference of the bottom surface of the installation cylinder 2. The pressing mold 24 slides in the slide grooves 243, and the pressing mold 24 is connected to the bottom wall of the installation cylinder 2 through a spring 241; a motor 22 is installed in the installation cavity 21, and a connecting disk 23 is installed on the output end of the motor 22, and the upper surface of the pressing mold 24 is in contact with the connecting disk 23; a protrusion 242 is fixedly connected to the bottom surface of the connecting disk 23, and the protrusion 242 corresponds to the pressing mold 24.

[0038] When in use, the device is placed upside down on the positioning die 3, and then the hydraulic drive system of the press 1 drives the connecting plate 11 downward to move closer to the pot body 4. The mounting cylinder 2 drives the multiple pressing dies 24 to descend synchronously. The pressing dies 24 cooperate with the pressing grooves 35 of the concave module 32 to complete the embossing depth of 70%-85% of the bottom of the pot body 4. This device enables the press 1 to complete most of the deformation through a one-time synchronous pressing process during the pressing process, so that the material at the bottom of the pot body 4 undergoes uniform plastic flow, eliminating the residual stress generated by the blank due to stretching, and thus suppressing deformation caused by warping of the pot body 4.

[0039] It should be understood that when the pressing die 24 presses down on the pot body 4 , the pressing die 24 abuts against the connecting plate 23 , so the pressing die 24 does not move upward.

[0040] When the pre-pressing stage is over, the motor 22 drives the connecting disk 23 to rotate, and the protrusion 242 pushes the pressing die 24 downward and squeezes the spring 1 241 to complete the remaining 15%-30% stroke precision pressing stage. The rotation of the connecting disk 23 can enable multiple pressing dies 24 to complete precision pressing in a step-by-step manner; specifically, adjacent pressing dies 24 are pressed down in turn at intervals of 0.5-1 seconds, so that the material of the pot body 4 can achieve gradient flow during the precision pressing process, avoiding stress superposition and causing deformation of the pot body 4. This makes it possible to effectively reduce the residual stress in the pressing process and improve the consistency of the embossing depth compared to the traditional full-stroke synchronous pressing method. The stepped pressing reduces the local contact time of the embossing die 24, which can effectively reduce the temperature generated when embossing the pot body 4. Therefore, when the device embosses the pot body 4, the press 1 performs a pre-pressing stage, laying the foundation for geometric accuracy through large-scale uniform plastic deformation, and the subsequent stepped static pressing stage uses local dynamic loading to achieve onlooker stress regulation. The two work together to significantly improve the anti-deformation ability, surface quality, and life of the embossing die 24 and concave module 32 of the pot body 4. Therefore, the device can significantly prevent deformation when embossing the pot body 4.

[0041] Among them, in this embodiment, the embossing mold 24 is in the shape of a long strip, so the embossing shape produced on the bottom of the pot body 4 is a plurality of long strips distributed in a circular array with the axis of the pot body 4 as the center. During the use of the pot body 4, a directional heat flow channel can be formed, and heat can quickly diffuse from the center of the bottom of the pot body 4 along the long stripes to the edge, reducing the overheating area in the center. Secondly, the embossing can also form annular reinforcement ribs to improve the deformation resistance.

[0042] Secondly, the embossing die 24 can also be in an arc shape, so that the pot body 4 is embossed to form multiple arc-shaped grooves distributed in a circular array with the axis of the pot body 4 as the center, which also has the effect of improving the performance of the pot body 4. Therefore, the cross-sectional shape of the embossing die 24 can be changed according to actual needs.

[0043] Example 2: Reference Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 A press machine for preventing deformation of aluminum pots is basically the same as that of Example 1, except that: a plurality of connecting arms 51 are mounted on the circumference of the mounting cylinder 2, and a pressing wheel 52 is connected to the connecting arm 51 via a spring, and the pressing wheel 52 is used to press the outer circumference of the pot body 4;

[0044] Among them, when the installation tube 2 moves downward, the four connecting arms 51 arranged in a circle will be located at the outer periphery of the pot body 4, and the clamping wheel 52 on the connecting arm 51 will produce a clamping effect on the pot body 4. On the one hand, it can prevent the pot body 4 from tilting on the positioning mold 3 when being pressed down, and on the other hand, it can apply pressure to the outer periphery of the pot body 4 toward the axis of the pot body 4 to further prevent deformation.

[0045] Example 3: Reference Figure 2 、 Figure 5 A press for preventing deformation of aluminum pots is basically the same as that of Example 2, except that: an insert rod 53 is slidably connected to the ends of two symmetrical connecting arms 51 via a spring, and a drive rod 5 is mounted on the mounting cylinder 2. The drive rod 5 is connected to the two symmetrical connecting arms 51 to control the raising and lowering of the connecting arms 51. The drive rod 5 is gas-driven or hydraulically driven.

[0046] When the forming is completed, before the installation cylinder 2 moves up, the execution end of the driving rod 5 extends downward, driving the connecting arm 51 connected to it to move downward, so that the front end of the insertion rod 53 is transferred to the front end surface of the opening of the pot body 4, and the front end of the insertion rod 53 is extended toward the center of the pot body 4 under the push of the spring. At this time, when the installation cylinder 2 moves up, the symmetrically arranged insertion rods 53 can drive the pot body 4 upward together, so that the pot body 4 is separated from the positioning mold 3, thereby facilitating the demoulding of the pot body 4 after forming.

[0047] When the pot body 4 moves upward along with the mounting tube 2 , the handle 55 at the end of the insertion rod 53 is pulled to retract the insertion rod 53 , thereby facilitating the removal of the pot body 4 .

[0048] In another embodiment, a cylinder 54 is installed on the two connecting arms 51 connected to the insertion rod 53, and the telescopic end of the cylinder 54 is connected to the insertion rod 53. When the installation tube 2 moves up, the cylinder 54 pulls the insertion rod 53 back, making it convenient to remove the pot body 4 from between the four connecting arms 51.

[0049] The positioning mold 3 is provided with a plurality of mounting grooves 31 on its circumference. The concave modules 32 are slidably connected in the mounting grooves 31. The bottom of the concave modules 32 is connected to the bottom wall of the mounting groove 31 via a second spring 33. The side walls of the mounting groove 31 are fixedly connected with limit blocks 34.

[0050] To further prevent deformation of the pot body 4 during demolding, a concave module 32 is connected to the positioning die 3 via a second spring 33. Initially, one end of the concave module 32 extends beyond the top surface of the positioning die 3. When the pressing die 24 presses downward, the concave module 32 retracts into the mounting groove 31, blocked by the stopper 34. This ensures that the top surface of the concave module 32 is level with the top surface of the positioning die 3. After molding, when the mounting cylinder 2 moves upward, the concave module 32 slides upward under the push of the second spring 33, lifting the pot body 4. Because the concave modules 32 are evenly arranged in a circular pattern on the positioning die 3, multiple concave modules 32 can evenly apply upward force to the pot body 4 to complete demolding, thereby effectively preventing deformation of the pot body 4.

[0051] Example 4: Reference Figure 6, an aluminum pot anti-deformation press, which is basically the same as Example 3, further comprising: a chamber 25 is opened in the mounting cylinder 2, and a piston rod 251 with a piston at one end is installed on the top of the two connecting arms 51 connected to the insertion rod 53. The piston rod 251 is slidably connected in the chamber 25, and an annular pipe 252 is installed in the mounting cylinder 2. The annular pipe 252 is provided with a plurality of nozzles 253 respectively facing the pressing mold 24, and the annular pipe 252 is connected to the chamber 25 through a one-way valve.

[0052] Before the installation cylinder 2 moves upward, when the driving rod 5 pushes the connecting arm 51 to move downward, the external lubricant is sucked into the chamber 25 through the piston rod 251. After the installation cylinder 2 is moved upward and the pot body 4 is removed, the execution end of the driving rod 5 drives the connecting arm 51 to retract. At this time, the piston rod 251 squeezes the lubricant in the chamber 25 into the annular pipe 252 and is sprayed toward the pressing mold 24 through the nozzle 253 to lubricate the pressing mold 24. On the one hand, it can cool the pressing mold 24 and the pot body 4 during pressing. On the other hand, it can reduce the friction coefficient between the pressing mold 24, the concave module 32 and the pot body 4, reduce the material flow resistance, and prevent circumferential corrugation deformation caused by friction drag.

[0053] It should be understood that a notch is provided on the slide groove 243 , which enables the lubricant sprayed on the pressing die 24 to flow to the bottom of the pressing die 24 through the notch, and when the pressing die 24 slides up and down in the slide groove 243 , the lubricant can also be replenished to the lower end part of the pressing die 24 .

[0054] The chamber 25 is connected to a suction pipe for sucking lubricant into the chamber 25 when the piston rod 251 moves downward. The suction pipe is connected to an oil storage tank, which is higher than the chamber 25. This allows the piston rod 251 to easily suck lubricant from the oil storage tank into the chamber 25 when it moves downward.

[0055] In another embodiment, a one-way valve is provided at the connection between the suction pipe and the annular pipe 252 and the chamber 25 to facilitate the suction of the lubricant into the chamber 25 .

[0056] In addition, it should be noted that the dosage sprayed from the nozzle 253 can be adjusted according to actual needs to avoid spraying too much or too little.

[0057] Example 5: Reference Figure 6 , an aluminum pot anti-deformation press, which is basically the same as Example 4, and further: a honeycomb protrusion block 6 is provided on the top surface of the positioning mold 3.

[0058] The honeycomb protrusions 6 are configured to form honeycomb recesses on the bottom wall of the pot body 4 when the pot body 4 is pressed. The honeycomb recesses form a truss-like structure, and each hexagonal unit is equivalent to a micro-reinforcement rib, further improving the pot body 4's ability to resist deformation during pressing. At the same time, the honeycomb recesses formed on the bottom wall of the pot body 4 can improve the pot body 4's anti-sticking performance.

[0059] In addition, when the pressing die 24 presses the bottom of the pot body 4 twice, it cooperates with the honeycomb protrusion block 6 to release residual stress through edge bending of the honeycomb hexagon during the precision pressing stage when honeycomb pits are generated, thereby further preventing the pot body 4 from deformation.

[0060] Furthermore, in the step coining stage, when the multiple embossing dies 24 are pressed down one by one, the honeycomb pits around the embossing can be made more obvious, thereby preventing the honeycomb pits around the embossing from being too shallow.

[0061] In one embodiment, oil injection pipes 321 are provided on both side walls of the concave module 32 , and the oil injection pipes 321 face the honeycomb protrusion block 6 ;

[0062] When the concave module 32 moves downward, the lubricant in the installation groove 31 will be squeezed and sprayed out from the oil spray pipe 321, so that when the bottom wall of the pot body 4 is pressed, the contact surface friction coefficient is effectively reduced, and the pot body 4 is prevented from adhering to the positioning mold 3 after pressing.

[0063] An oil inlet pipe is provided in the mounting groove 31 for sucking external lubricant into the mounting groove 31. A one-way valve is provided in both the oil injection pipe 321 and the oil inlet pipe.

[0064] Example 6: Reference Figures 1-9 A method for using an aluminum pot anti-deformation press comprises the following steps:

[0065] S1. Place the pot body 4 upside down on the positioning mold 3, and drive the installation cylinder 2 to move down close to the positioning mold 3;

[0066] S2, the pressing die 24 presses the pot body 4 synchronously to 70%-85% of the stroke to eliminate the residual stress of the material, and the honeycomb protrusion block 6 pre-presses a pit on the bottom of the pot;

[0067] S3, the motor 22 drives the connecting plate 23 to rotate, and the protrusion 242 pushes the pressing die 24 at intervals to complete the pressing of the remaining 15%-30% of the stroke;

[0068] S4, the insertion rod 53 moves downward and extends to the pot mouth of the pot body 4, and the installation tube 2 moves upward to drive the pot body 4 to be demoulded.

[0069] The present invention performs a pre-pressing stage (70%-85% of the stroke) by the press machine 1 and synchronously presses down through the pressing die 24, so that the material at the bottom of the pot body 4 completes uniform plastic flow, eliminates tensile residual stress, and provides geometric stability for subsequent precision pressing. Then, a step-by-step precision pressing stage (remaining 15%-30% of the stroke) is performed, and the motor 22 drives the protrusion 242 to push the pressing die 24 in sequence, loading in sequence at intervals of 0.5-1 seconds to disperse stress peaks, and uses the spring 1 241 for elastic compensation to correct local micro deformation, thereby preventing the pot body 4 from deformation.

[0070] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with the present invention can make slight changes or modifications to equivalent embodiments using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
