Description

Technical Field

[0001] This utility model belongs to the field of bracket manufacturing technology, specifically relating to a stamping device for bracket production. Background Technology

[0002] Mounting brackets typically refer to auxiliary tools or connecting components used when installing electromechanical or electronic equipment. During the manufacturing process of mounting brackets, stamping is required to produce brackets with non-flat shapes.

[0003] According to a sheet metal stamping device with application number CN202222224402.2, although this patented technology has the advantages of automatically removing the workpiece from the stamping head by using a telescopic rod to drive the collection box and the scraper on top of the collection box, thus replacing manual operation and improving the efficiency of workpiece removal, it also effectively avoids the dangers of manual workpiece removal. However, this patented technology has the following defects in actual use: during stamping, the workpiece will shift at the moment the stamping head contacts the workpiece, and the stamping position of the workpiece cannot be quickly positioned when placing it, which will lead to incorrect stamping position. In addition, after stamping, the workpiece is very easy to get stuck in the mold base and difficult to demold, which will lead to the inability to automatically remove the material. Therefore, we propose a stamping device for bracket production. Utility Model Content

[0004] The purpose of this invention is to provide a stamping device for bracket production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamping device for bracket production, comprising a base, an L-shaped plate fixedly connected to the top of the base, an electric push rod fixedly connected to the top of the L-shaped plate, the electric push rod penetrating the L-shaped plate, a movable plate fixedly connected to the output end of the electric push rod, a pressure plate fixedly connected to the bottom of the movable plate, a die fixedly connected to the bottom of the pressure plate, four sliding rods slidably connected inside the movable plate, the sliding rods penetrating the L-shaped plate, the movable plate, and the pressure plate, a square frame fixedly connected to the bottom of the four sliding rods, the square frame and the movable plate being fixedly connected by a spring, an anti-slip protrusion fixedly connected to the bottom of the square frame, the spring penetrating the pressure plate, and a die fixedly connected to the top of the base.

[0006] In a preferred embodiment, a push rod is slidably connected inside the mold, the push rod passes through the mold, a semi-cylinder is fixedly connected to one side of the L-shaped plate, the push rod is slidably connected inside the semi-cylinder, the push rod passes through the L-shaped plate, and one end of the push rod is located above the movable plate.

[0007] In a preferred embodiment, a vertical plate is fixedly connected to one side of the top of the base, and a first limiting screw is rotatably connected inside the vertical plate. The first limiting screw passes through the vertical plate, and an adjusting plate is threadedly connected to the first limiting screw. The adjusting plate is slidably connected inside the base.

[0008] In a preferred embodiment, a second limiting screw is rotatably connected inside the adjusting plate, and a limiting block is threadedly connected to the second limiting screw. The limiting block is slidably connected inside the adjusting plate.

[0009] In a preferred embodiment, a motor is fixedly connected to the inner cavity of the base, a drive gear is fixedly connected to the output shaft of the motor, a driven gear is meshed with the top of the drive gear, a feeding screw is fixedly connected inside the driven gear, and the feeding screw is rotatably connected inside the base.

[0010] In a preferred embodiment, a feeding plate is threadedly connected to the feeding screw, the feeding plate passes through the base and the mold, and the feeding plate is slidably connected inside the mold.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The stamping device for producing this bracket is equipped with a moving plate, a pressure plate, a slide bar, a spring, and a square frame. During stamping, the output end of the electric push rod extends, causing the moving plate and pressure plate to descend. The descent of the moving plate causes the slide bar, spring, and square frame to descend, so that the square frame contacts the workpiece first. The output end of the electric push rod continues to extend, and the spring is compressed, causing the square frame to hold the workpiece in place, thereby preventing the workpiece from shifting at the moment of stamping. 2. The stamping device for bracket production is equipped with a first limit screw, an adjusting plate, a second limit screw, and a limit block. Rotating the first limit screw moves the adjusting plate, and rotating the second limit screw moves the limit block. After adjusting the positions of the limit block and the adjusting plate, the workpiece is placed above the mold so that it simultaneously contacts the adjusting plate and the limit block, thus placing the workpiece in the appropriate position and quickly positioning the stamping position of the workpiece. This avoids the problem of incorrect stamping position due to incorrect workpiece placement. 3. The stamping device for producing this bracket, by setting an ejector rod and a semi-cylinder, allows the output end of the electric push rod to retract after stamping, driving the moving plate to rise. During the rising process of the moving plate, one end of the ejector rod will be lifted, causing the ejector rod to rise. The rising ejector rod will push the stamped workpiece out of the mold, facilitating the demolding of the workpiece. Attached Figure Description

Detailed Implementation

[0014] The present invention will be further described below with reference to the embodiments.

[0015] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0016] Please see Figures 1-5 This utility model provides a stamping device for bracket production, including a base 1. To prevent the workpiece from shifting during stamping, an L-shaped plate 2 is fixedly connected to the top of the base 1. An electric push rod 3 is fixedly connected to the top of the L-shaped plate 2, penetrating the L-shaped plate 2. A movable plate 4 is fixedly connected to the output end of the electric push rod 3. A pressure plate 5 is fixedly connected to the bottom of the movable plate 4. A die 6 is fixedly connected to the bottom of the pressure plate 5. Four sliding rods 7 are slidably connected inside the movable plate 4, penetrating the L-shaped plate 2, the movable plate 4, and the pressure plate 5. A square frame 8 is fixedly connected to the bottom of the four sliding rods 7. The square frame 8 and the movable plate 4 are connected together. The square frame 8 is fixedly connected by spring 9, and the bottom of the square frame 8 is fixedly connected with anti-slip protrusions. Spring 9 passes through pressure plate 5, and mold 10 is fixedly connected to the top of base 1. The workpiece is placed above mold 10, and electric push rod 3 is activated, so that the output end of electric push rod 3 extends, driving moving plate 4 and pressure plate 5 to descend. The descent of moving plate 4 drives slide rod 7, spring 9 and square frame 8 to descend, so that square frame 8 contacts workpiece first. The output end of electric push rod 3 continues to extend, and spring 9 is compressed, so that square frame 8 presses the workpiece to prevent the workpiece from shifting at the moment of stamping. Pressure plate 5 drives mold 6 to descend and press the workpiece into mold 10 to complete stamping.

[0017] Please see Figure 1 and Figure 2To quickly position the workpiece for stamping, a vertical plate is fixedly connected to one side of the top of the base 1. A first limiting screw 12 is rotatably connected inside the vertical plate, passing through the vertical plate. An adjusting plate 13 is threaded onto the first limiting screw 12 and slidably connected inside the base 1. A second limiting screw 14 is rotatably connected inside the adjusting plate 13 and threaded onto the second limiting screw 14. The limiting block 15 is slidably connected inside the adjusting plate 13. Rotating the first limiting screw 12 moves the adjusting plate 13, and rotating the second limiting screw 14 moves the limiting block 15. After adjusting the positions of the limiting block 15 and the adjusting plate 13, the workpiece is placed above the mold 10, so that the workpiece simultaneously contacts the adjusting plate 13 and the limiting block 15, thus placing the workpiece in the appropriate position and quickly positioning the workpiece for stamping.

[0018] Please refer to the figure. Figures 1-3 To facilitate demolding of the stamped workpiece, an ejector rod 11 is slidably connected inside the mold 10. The ejector rod 11 passes through the mold 10. A semi-cylinder 21 is fixedly connected to one side of the L-shaped plate 2. The ejector rod 11 is slidably connected inside the semi-cylinder 21 and passes through the L-shaped plate 2. One end of the ejector rod 11 is located above the moving plate 4. After stamping, the output end of the electric push rod 3 retracts, driving the moving plate 4 to rise. During the rising process of the moving plate 4, one end of the ejector rod 11 will be lifted, causing the ejector rod 11 to rise. The rising ejector rod 11 pushes the stamped workpiece out of the mold 10, facilitating demolding of the workpiece.

[0019] Please see Figure 1 and Figure 2 To facilitate material unloading, a motor 16 is fixedly connected to the inner cavity of the base 1. A drive gear 17 is fixedly connected to the output shaft of the motor 16. A driven gear 18 is meshed with the top of the drive gear 17. A material unloading screw 19 is fixedly connected inside the driven gear 18. The material unloading screw 19 is rotatably connected inside the base 1. A material unloading plate 20 is threaded onto the material unloading screw 19. The material unloading plate 20 passes through the base 1 and the mold 10 and is slidably connected inside the mold 10. When the motor 16 is started, the output shaft of the motor 16 rotates, which drives the drive gear 17 to rotate. The drive gear 17 drives the driven gear 18 to rotate, which in turn drives the material unloading screw 19 to rotate. This causes the material unloading plate 20 to move left and right. The movement of the material unloading plate 20 pushes out the stamped workpiece, facilitating material unloading and avoiding the need for manual removal of the workpiece from under the die 6, thus preventing accidents and ensuring personnel safety.

[0020] The working principle and usage process of this utility model are as follows: First, place the workpiece above the mold 10. Start the electric push rod 3, causing its output end to extend, which in turn drives the moving plate 4 and pressure plate 5 to descend. The descent of the moving plate 4 causes the sliding rod 7, spring 9, and square frame 8 to descend, so that the square frame 8 contacts the workpiece first. The output end of the electric push rod 3 continues to extend, and the spring 9 is compressed, causing the square frame 8 to hold the workpiece in place, preventing displacement of the workpiece during the stamping process. The pressure plate 5 drives the die 6 to descend, pressing the workpiece into the mold 10 to complete the stamping. Rotate the first limit screw 12 to move the adjusting plate 13. Rotate the second limit screw 14 to move the limit block 15. Adjust the positions of the limit block 15 and the adjusting plate 13, and place the workpiece above the mold 10 so that the workpiece simultaneously contacts the adjusting plate 15. When the electric push rod 3 contacts the limiting block 15, the workpiece can be placed in a suitable position, quickly positioning the stamping position of the workpiece. After stamping, the output end of the electric push rod 3 retracts, driving the moving plate 4 to rise. During the rising process of the moving plate 4, one end of the ejector rod 11 will be lifted, causing the ejector rod 11 to rise. The rising ejector rod 11 will push the stamped workpiece out of the mold 10, facilitating the demolding of the workpiece. The motor 16 is started, causing the output shaft of the motor 16 to rotate, driving the drive gear 17 to rotate. The drive gear 17 drives the driven gear 18 to rotate, and the driven gear 18 drives the unloading screw 19 to rotate, thereby causing the unloading plate 20 to move left and right. The movement of the unloading plate 20 pushes out the stamped workpiece, facilitating unloading and avoiding the need for manual removal of the workpiece under the die 6, preventing accidents and ensuring personnel safety.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
