Description

Technical Field

[0001] This utility model relates to the field of automatic demolding technology, specifically to an automatic stamping demolding device for aluminum alloy products. Background Technology

[0002] Stamping is a processing method that uses a punch press and dies to apply pressure to materials such as sheet metal, strip, tube and profile, causing the material to separate or plastically deform, thereby obtaining the desired shape and size.

[0003] Currently, most stamping equipment requires manual removal of the formed product from the mold using tools or by hand after stamping. This not only increases the workload of manual operation but also places certain demands on the skills and experience of the operators. Improper operation may damage the product or the mold, which undoubtedly affects production efficiency and product quality. Moreover, the material movement during stamping can cause uneven distribution of stamping pressure, affecting the internal structure and surface quality of the product. Therefore, an automatic stamping and demolding device for aluminum alloy products is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an automatic stamping and demolding equipment for aluminum alloy products to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A workbench is included, with an installation groove on one side of the top of the workbench. A conveyor belt is rotatably installed inside the installation groove. Four guide columns are connected to the top of the workbench, arranged in a rectangular pattern. A top plate is connected to the top surface of each guide column. A hydraulic cylinder is connected to the top of the top plate. The output end of the hydraulic cylinder penetrates the top plate and is connected to a push plate, which is slidably mounted on the surface of the guide columns. An upper mold is connected to the bottom end of the push plate, and a mold groove is formed at the bottom end of the upper mold. Placement grooves are formed on both sides of the top of the workbench. A cavity is formed between the two placement grooves at the top of the workbench, and a demolding assembly is connected inside the cavity. A motor is connected to one side of the workbench, and a bidirectional lead screw is connected to the output end of the motor. One end of the bidirectional lead screw penetrates the workbench and extends into the two placement grooves. A sliding rod is connected to the other side of the two placement grooves, and a sliding plate is threaded onto the surface of the bidirectional lead screw.

[0006] Preferably, the demolding assembly includes a demolding shell connected to the top of the cavity, a base plate connected to the bottom of the demolding shell, a protrusion connected to the center of the top of the base plate, two notches on both sides of the top of the base plate, an L-shaped rotating block rotatably disposed inside each of the two notches, through holes on both sides of the demolding shell corresponding to the L-shaped rotating blocks, four connecting rods slidably disposed on the top of the base plate, a demolding template connected to the top of the connecting rods and slidably disposed inside the demolding shell, the other end of the connecting rods penetrating the base plate and connected to a pad, the pad slidably disposed inside the demolding shell, and a spring connected between the bottom of the demolding shell and the bottom of the pad; By adopting the above technical solution, when the demolding template is subjected to stamping, the demolding template can drive the connecting rod to move downward and compress the spring. After the stamping is completed, the spring can push the pad to move upward. The pad drives the connecting rod and the demolding template to move upward, realizing demolding. At the same time, the L-shaped rotating block can slide along the surface of the demolding template through the roller under the push of the demolding template. When the demolding template moves upward, the L-shaped rotating block can automatically reset under the action of the spring and the elastic force of the torsion spring, thus facilitating the next demolding operation.

[0007] Preferably, a torsion spring is provided at the connection between the L-shaped rotating block and the notch, a roller is rotatably provided on one side of the long end of the L-shaped rotating block, and the initial state of the L-shaped rotating block is that the long end is raised, and the roller is in contact with the bottom end of the demolding template; By adopting the above technical solution, when the demolding template is subjected to stamping, the demolding template can drive the connecting rod to move downward and compress the spring. At the same time, the L-shaped rotating block can slide along the surface of the demolding template through the roller under the push of the demolding template. After the stamping is completed, the spring can push the pad to move upward. The pad drives the connecting rod and the demolding template to move upward, realizing demolding. At this time, the L-shaped rotating block can automatically return to the initial state, that is, the long end is raised, under the action of the spring and the elastic force of the torsion spring, thus facilitating the next demolding operation.

[0008] Preferably, one end of the slide plate is threaded onto the surface of the bidirectional lead screw, and the other end is slidably mounted on the surface of the slide bar. The top of the slide plate is rotatably provided with multiple rotating clamping components. By adopting the above technical solution, the motor can drive the bidirectional lead screw to rotate, and the bidirectional lead screw drives the slide plate to slide along the surface of the slide bar. At the same time, the rotating clamping part at the top of the slide plate can clamp and fix the aluminum alloy product, thereby facilitating the transportation of the aluminum alloy product into the mold groove for stamping processing, improving the automation level of the equipment and reducing the intensity of manual labor.

[0009] Preferably, a cutting blade is connected to the bottom end of the push plate on the side away from the conveyor belt; By adopting the above technical solution, the stamped sheet metal is cut into smaller pieces.

[0010] Preferably, a guide groove is provided on the side of the top of the workbench away from the conveyor belt; By adopting the above technical solution, the boards cut into small pieces can be easily processed centrally by operators.

[0011] Preferably, four springs are provided, and the four springs are arranged in a rectangular shape, and a protrusion groove is provided at the top of the ejector plate corresponding to the protrusion; By adopting the above technical solution, the setting of four springs can make the demolding template more uniformly stressed when it is stamped, thus improving the stability and efficiency of demolding. At the same time, the setting of the bump groove can make the bump and the demolding template fit more tightly, further improving the demolding effect.

[0012] Compared with the prior art, the advantages of this application are as follows: After stamping, the L-shaped rotating block, torsion spring, roller and spring in the demolding assembly can automatically eject the molded product from the mold under the action of the spring and other structures, without manual intervention, reducing manual operation, reducing labor intensity, and improving demolding efficiency; The motor drives the bidirectional lead screw to rotate, which drives the slide plate to move along the slide bar. The rotating clamping part at the top of the slide plate can clamp and fix the material or product, ensuring the stability of the material position during the stamping process, preventing material displacement and improving the stamping quality.

[0015] 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.

[0016] Please see Figures 1-5 This utility model provides a technical solution, including a workbench 1. A mounting groove 2 is formed on one side of the top of the workbench 1. A conveyor belt 3 is rotatably mounted inside the mounting groove 2. Four guide columns 4 are connected to the top of the workbench 1, and the four guide columns 4 are arranged in a rectangular pattern. A top plate 5 is connected to the top surface of the guide columns 4. A hydraulic cylinder 6 is connected to the top of the top plate 5. The output end of the hydraulic cylinder 6 passes through the top plate 5 and is connected to a push plate 7, which is slidably mounted on the surface of the guide columns 4. An upper mold 8 is connected to the bottom end of the push plate 7. The bottom of the tool 8 has a model groove 9, and the top of the worktable 1 has placement grooves 10 on both sides. The top of the worktable 1 has a cavity 101 between the two placement grooves 10. A demolding component 11 is connected inside the cavity 101. A motor 12 is connected to one side of the worktable 1. A bidirectional lead screw 13 is connected to the output end of the motor 12. One end of the bidirectional lead screw 13 passes through the worktable 1 and extends into the two placement grooves 10. A slide rod 14 is connected to the other side of the two placement grooves 10. A sliding plate 15 is threaded on the surface of the bidirectional lead screw 13.

[0017] The demolding assembly 11 includes a demolding shell 110 connected to the top of the cavity 101. A base plate 112 is connected to the bottom of the demolding shell 110. A protrusion 113 is connected to the center of the top of the base plate 112. Two notches 114 are opened on both sides of the top of the base plate 112. An L-shaped rotating block 115 is rotatably installed inside each of the two notches 114. Through holes 116 are opened on both sides of the demolding shell 110 corresponding to the L-shaped rotating blocks 115. Four connecting rods 117 are slidably installed on the top of the base plate 112. A demolding template 118 is connected to the top and slidably disposed inside the demolding shell 110. The other end of a connecting rod 117 passes through the base plate 112 and is connected to a pad 119, which is also slidably disposed inside the demolding shell 110. A spring 120 is connected between the bottom end of the demolding shell 110 and the bottom end of the pad 119. Its function is that when the demolding template 118 is pushed by the hydraulic cylinder 6 for stamping, the demolding template 118 can drive the connecting rod 117 downwards, thereby compressing the spring 120. The compression of the spring 120 stores energy for the demolding process. Simultaneously, the L-shaped rotating block 115, pushed by the demolding template 118, slides along the surface of the demolding template 118 via rollers 121, ensuring that the demolding template 118 descends smoothly. After stamping is completed, the output end of the hydraulic cylinder 6 retracts, at which point the spring 120 releases the stored energy, pushing the pad 119 upwards. The rising of the pad 119 causes the connecting rod 117 and the demolding template 118 to rise together, realizing automatic demolding of aluminum alloy products. This not only improves the efficiency and stability of demolding, but also greatly reduces manual intervention and labor intensity.

[0018] A torsion spring is provided at the connection between the L-shaped rotating block 115 and the notch 114. A roller 121 is rotatably mounted on one side of the long end of the L-shaped rotating block 115, and the initial state of the L-shaped rotating block 115 is with the long end raised. The roller 121 is in contact with the bottom end of the ejector plate 118. Its function is that when the ejector plate 118 descends during the stamping process, the roller 121 of the L-shaped rotating block 115 can slide along the bottom surface of the ejector plate 118. This design not only reduces friction but also ensures the stability of the ejector plate 118 during the descent. At the same time, because a torsion spring is provided between the L-shaped rotating block 115 and the notch 114, when the ejector plate 118 rises, the L-shaped rotating block 115 can automatically return to its initial state, i.e., the long end raised state, under the action of the torsion spring, preparing for the next stamping and demolding process. This automatic reset design greatly simplifies the operation process and improves the automation level of the equipment.

[0019] One end of the slide plate 15 is threaded onto the surface of the bidirectional lead screw 13, and the other end is slidably mounted on the surface of the slide bar 14. Multiple rotating clamping elements 16 are rotatably mounted on the top of the slide plate 15. Their function is to allow the motor 12 to drive the bidirectional lead screw 13 to rotate. Since one end of the slide plate 15 is threaded to the bidirectional lead screw 13 and the other end slides on the slide bar 14, the rotation of the bidirectional lead screw 13 causes the slide plate 15 to move linearly along the slide bar 14. This design allows the slide plate 15 to move flexibly in the horizontal direction, facilitating the transport of aluminum alloy products to designated positions. Simultaneously, the rotating clamping elements 16 at the top of the slide plate 15 can rotate and clamp the aluminum alloy products, ensuring stability during transport and stamping, preventing displacement due to vibration or external forces, thus guaranteeing stamping accuracy and quality. Furthermore, the design of the rotating clamping elements 16 also facilitates quick clamping and release of products by operators, improving work efficiency.

[0020] A cutting blade 17 is connected to the bottom end of the push plate 7, away from the conveyor belt 3. Its function is to cut the stamped sheet into smaller pieces as the push plate 7 continues to descend after stamping, facilitating subsequent collection and processing. This simplifies the operation process, improves work efficiency, and reduces manual cutting steps. Furthermore, the cutting blade 17 is strategically positioned away from the conveyor belt 3, avoiding interference with other materials or products on the conveyor belt and ensuring smooth cutting.

[0021] A guide groove 18 is provided on the top side of the workbench 1 away from the conveyor belt 3. The purpose of the guide groove 18 is to guide the small pieces of board after cutting to slide down in a specific direction, making it easier for operators to collect and process them. The design of the guide groove 18 takes into account the cutting size and sliding path of the board, ensuring that the cut board can slide smoothly to the designated position, avoiding the accumulation and scattering of the board, and further improving work efficiency and ease of operation.

[0022] Four springs 120 are provided, arranged in a rectangular pattern. A groove 19 is provided at the top of the ejector plate 118 corresponding to the protrusion 113. This rectangular arrangement of the four springs ensures that the ejector plate 118 receives more even force during stamping, preventing unstable demolding or product damage due to uneven force. This design also improves demolding stability and efficiency, making the demolding process smoother. Furthermore, the groove 19 at the top of the ejector plate 118 cooperates with the protrusion 113 at the top of the base plate 112, further enhancing the connection stability between the ejector plate 118 and the base plate 112, ensuring precise mold alignment during demolding, and improving demolding effect and product molding quality.

[0023] The implementation principle of this application is as follows: The operator first places the aluminum alloy product to be stamped on the conveyor belt 3, which then transports the stamped part to the rotating clamping member 16 at the top of the slide plate 15. Then, the motor 12 is started, driving the bidirectional lead screw 13 to rotate. The rotation of the bidirectional lead screw 13 causes the slide plate 15 to move horizontally along the slide bar 14, accurately conveying the aluminum alloy product to the mold groove 9 below the upper mold 8. At this time, the hydraulic cylinder 6 is activated, pushing the push plate 7 downwards. The upper mold 8 at the bottom of the push plate 7 then descends, stamping the aluminum alloy product placed in the mold groove 9. During the stamping process, the ejector plate 118 is subjected to the stamping force of the upper mold 8, causing the connecting rod 117 to move downwards, thereby compressing the spring 120. Simultaneously, the roller 121 of the L-shaped rotating block 115 slides along the bottom surface of the ejector plate 118, reducing friction and ensuring the smooth descent of the ejector plate 118. After stamping is completed, the output end of hydraulic cylinder 6 retracts, spring 120 releases its stored energy, pushing pad 119 and connecting rod 117 upward, causing demolding template 118 to rise together, thus achieving automatic demolding of the aluminum alloy product. At this time, L-shaped rotating block 115 automatically returns to its initial state under the action of torsion spring, preparing for the next stamping and demolding process. Simultaneously with stamping, push plate 7 descends, and its bottom cutting blade 17 cuts the stamped sheet metal into small pieces. These small pieces slide down in a specific direction to a designated position under the guidance of guide groove 18, facilitating collection and processing by operators.
