Description

Technical Field

[0001] This utility model belongs to the field of aluminum alloy processing technology, and in particular relates to an aluminum alloy brake chamber stamping device. Background Technology

[0002] Aluminum alloy brake chambers are one of the key components in automotive braking systems, and their quality directly affects the performance and safety of the braking system. In the production process of aluminum alloy brake chambers, stamping is an important forming step. However, when existing stamping equipment is used, its rigid stamping method is prone to wear after long-term use, resulting in misalignment of the upper and lower dies. After stamping, the size and shape of the brake chamber are prone to differences, and its precision is difficult to meet the design requirements, affecting product quality. Utility Model Content

[0003] The purpose of this invention is to provide an aluminum alloy brake chamber stamping device. By setting a limiting groove, specifically, when the stamping machine is started, the upper mold moves downward to contact the lower mold, and the aluminum alloy is stamped and formed. During stamping, the slider slides on the inner wall of the limiting groove, providing precise guidance for the upper mold. The top of the buffer plate contacts the bottom of the operating table, and the spring force at the bottom of the buffer plate dynamically compensates for the springback of the upper mold during stamping. This solves the problem that the size and shape of the brake chamber are prone to differences after stamping in existing stamping devices, which affects product quality.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to an aluminum alloy brake chamber stamping device, comprising an operating table and a stamping machine. A lower die is fixedly connected to the top of the operating table, and an upper die is in contact with the top of the lower die. The top of the upper die is fixedly connected to the bottom output end of the stamping machine. Four sliders are fixedly connected to the outer surface of the upper die, and limit grooves are slidably connected to the outer surface of the sliders. A support block is fixedly connected to one side of two corresponding limit grooves. The bottom of the support block is fixedly connected to the top of the operating table. A buffer plate is slidably connected to the bottom of the limit grooves, and the top of the buffer plate is in contact with the bottom of the slider. A spring is fixedly connected to the bottom of the buffer plate, and the bottom of the spring is fixedly connected to the top of the operating table. The sliding guide structure of the sliders and limit grooves enhances the stability of the vertical movement of the upper die, avoids poor workpiece forming caused by skewing, and dynamically compensates for the springback of the upper die after stamping by combining the spring and the buffer plate, thereby improving stamping efficiency.

[0006] Furthermore, the lower mold has several push rods slidably connected inside, the bottom of the operating table has a sliding groove, the inner wall of the sliding groove has a connecting plate slidably connected, and the top of the connecting plate is fixedly connected to the bottom of the push rod.

[0007] Furthermore, an electric push rod is fixedly connected to the bottom of the operating table via a support frame. The top output end of the electric push rod is fixedly connected to the bottom of the connecting plate. The linkage design between the push rod and the connecting plate can quickly eject the workpiece after stamping, avoiding workpiece deformation or mold damage caused by manual prying.

[0008] Furthermore, two support blocks are fixedly connected to the top of the operating table near the left side of the lower mold. Two feeding rollers are rotatably connected to the corresponding side of the two support blocks. An electric push rod provides stable power to drive the push rod to eject the workpiece, realizing automated demolding, improving production efficiency and reducing operational risks.

[0009] Furthermore, several anti-slip blocks are fixedly connected to the outer surface of the feeding roller. Gear 1 is fixedly connected to the front of the upper feeding roller, and gear 2 is fixedly connected to the front of the lower feeding roller. The cooperation structure between the support block 2 and the feeding roller can stably transport aluminum alloy sheets to the stamping station, reduce manual intervention, and ensure the smoothness of continuous production.

[0010] Furthermore, the bottom of gear one is meshed with the top of gear two, and a motor is fixedly connected to the front of the support block two located on the front. The output end of the motor on the back is fixedly connected to the front of gear two. The anti-slip block increases the friction between the feeding roller and the plate, preventing slippage. The gear meshing transmission ensures that the upper and lower feeding rollers rotate synchronously, improving the feeding accuracy.

[0011] Furthermore, a feeding frame is fixedly connected to the left side of the feeding roller via a support frame, and a waste trough is fixedly connected to the top of the operating table. The feeding frame guides the sheet metal accurately into the stamping area, and the waste trough collects stamping waste, keeping the operating table clean and improving operational safety and efficiency.

[0012] This utility model has the following beneficial effects:

[0013] This utility model, by setting a limiting groove, specifically starts the stamping machine, drives the upper mold to move downward and contact the lower mold to stamp aluminum alloy. During stamping, the slider slides on the inner wall of the limiting groove to provide precise guidance for the upper mold. The top of the buffer plate contacts the bottom of the operating table, and the spring force at the bottom of the buffer plate is used to dynamically compensate for the springback of the upper mold during stamping, thereby improving the forming accuracy and stamping efficiency.

[0014] This utility model, by setting up feeding rollers, specifically first passes the aluminum alloy on the feeding frame through the space between two feeding rollers, starts the motor, drives gear two to rotate, and due to the meshing relationship between gear one and gear two, drives the two feeding rollers to rotate synchronously in opposite directions, feeding out the aluminum alloy. Anti-slip blocks are set on the outer surface of the feeding rollers to prevent slippage, and automatic feeding avoids manual intervention, thus improving production efficiency.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] Please see Figures 1-5As shown, this utility model is an aluminum alloy brake chamber stamping device, including an operating table 1 and a stamping machine 2. A lower mold 11 is fixedly connected to the top of the operating table 1, and an upper mold 12 is in contact with the top of the lower mold 11. The top of the upper mold 12 is fixedly connected to the bottom output end of the stamping machine 2. Four sliders 121 are fixedly connected to the outer surface of the upper mold 12. Limiting grooves 122 are slidably connected to the outer surface of the sliders 121. Support blocks 123 are fixedly connected to one side of two corresponding limiting grooves 122. The bottom of the support blocks 123 is fixedly connected to the top of the operating table 1. A buffer plate 13 is slidably connected to the bottom of the limiting grooves 122. The top of the buffer plate 13 contacts the bottom of the slider 121. A spring 131 is fixedly connected to the bottom of the buffer plate 13. The bottom of the spring 131 is fixedly connected to the top of the operating table 1. By setting a limiting groove 122, specifically, the stamping machine 2 is started, which drives the upper mold 12 to move downward and contact the lower mold 11 to stamp the aluminum alloy. During stamping, the slider 121 slides on the inner wall of the limiting groove 122 to provide precise guidance for the upper mold 12. The top of the buffer plate 13 contacts the bottom of the operating table 1. The elastic force of the spring 131 at the bottom of the buffer plate 13 is used to dynamically compensate for the springback of the upper mold 12 during stamping, thereby improving the forming accuracy and stamping efficiency.

[0026] The lower mold 11 has several push rods 14 slidably connected inside. The bottom of the operating table 1 has a slide groove 141. A connecting plate 142 is slidably connected to the inner wall of the slide groove 141. The top of the connecting plate 142 is fixedly connected to the bottom of the push rod 14.

[0027] An electric push rod 143 is fixedly connected to the bottom of the control panel 1 via a support frame, and the top output end of the electric push rod 143 is fixedly connected to the bottom of the connecting plate 142.

[0028] Two support blocks 15 are fixedly connected to the top of the operating table 1 near the left side of the lower mold 11. Two feeding rollers 151 are rotatably connected to the corresponding side of the two support blocks 15.

[0029] Several anti-slip blocks 152 are fixedly connected to the outer surface of the feeding roller 151. Gear 153 is fixedly connected to the front of the upper feeding roller 151, and gear 2 154 is fixedly connected to the front of the lower feeding roller 151.

[0030] The bottom of gear 153 meshes with the top of gear 2154. A motor 155 is fixedly connected to the front of the support block 215 located on the front. The output end of the motor 155 is fixedly connected to the front of gear 2154. By setting up feeding rollers 151, the aluminum alloy on the feeding frame 16 is first passed between the two feeding rollers 151. The motor 155 is started, which drives gear 2154 to rotate. Due to the meshing relationship between gear 153 and gear 2154, the two feeding rollers 151 will rotate synchronously in opposite directions, feeding out the aluminum alloy. Anti-slip sliders 152 are set on the outer surface of the feeding rollers 151 to prevent slippage. Automatic feeding avoids manual intervention and improves production efficiency.

[0031] A feeding rack 16 is fixedly connected to the left side of the feeding roller 151 via a support frame, and a waste trough 17 is fixedly connected to the top of the operating table 1.

[0032] A specific application of this embodiment is as follows: In use, the aluminum alloy on the feeding rack 16 is first passed between the two feeding rollers 151. The motor 155 is started, driving the gear 154 to rotate. Due to the meshing relationship between gear 153 and gear 154, the two feeding rollers 151 will rotate synchronously in opposite directions, feeding the aluminum alloy out. Anti-slip blocks 152 are provided on the outer surface of the feeding rollers 151 to prevent slippage. Then, the stamping press 2 is started, driving the upper die 12 to move downwards and contact the lower die 11, stamping the aluminum alloy into shape. When pressing, the slider 121 slides on the inner wall of the limiting groove 122 to provide precise guidance for the upper mold 12. The top of the buffer plate 13 contacts the bottom of the operating table 1. The spring force of the bottom spring 131 of the buffer plate 13 is used to dynamically compensate for the springback of the upper mold 12 during stamping. After stamping is completed, the electric push rod 143 is activated, which drives the connecting plate 142 to slide on the inner wall of the slide groove 141, so that the push rod 14 slides inside the lower mold 11 to push out the formed part. The waste generated during stamping can be placed in the waste tank 17 for collection.
