Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die for a back plate of a television. Background Art

[0002] With the continuous development of television manufacturing technology, the back panel, as an important component of the television, has a significant impact on the performance and cost of the entire machine due to its quality and production efficiency. During the production of the TV back panel, the stamping die is used to apply pressure to the material to cause separation or plastic deformation, thereby obtaining the required TV back panel parts. This mold design can ensure the dimensional accuracy and surface quality of the back panel, while improving production efficiency and reducing production costs.

[0003] The existing stamping dies for TV back panels generally lack adequate protection for operators in their designs, which leads to safety hazards that cannot be ignored during the stamping process. Due to the lack of an effective protection mechanism, the die may break during high-speed stamping, and the splashing of fragments may not only damage the equipment, but also cause physical harm to the operator. These safety hazards not only affect the personal safety of the operator, but also restrict the efficiency and quality of TV back panel stamping production. Therefore, we propose a stamping die for TV back panels. Utility Model Content

[0004] The purpose of the utility model is to provide a stamping die for a television back panel, so as to solve the problem mentioned in the above background technology that the existing stamping dies for television back panels generally lack sufficient protection functions for operators in their designs, which leads to safety hazards that cannot be ignored during the stamping process. Due to the lack of an effective protection mechanism, the die may crack during high-speed stamping, and the flying fragments may not only damage the equipment, but also cause physical harm to the operator. These safety hazards not only affect the personal safety of the operator, but also restrict the production efficiency and quality of the television back panel stamping.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stamping die for a back panel of a television, comprising a base, a support base is fixedly installed at the center of the bottom inner portion of the base, a damping pad is fixedly connected to the upper end of the support base, a fixed mold is fixedly connected to the top of the damping pad, a protective cover is arranged on the outside of the fixed mold, a rack is fixedly installed at the center of one side of the protective cover, a gear is meshingly connected to the lower end of one side of the rack, a motor is fixedly installed at a position close to the top on one side of the front surface of the base, sliding parts are fixedly installed at the front and rear ends of the bottom of the other side of the protective cover, slide rails are fixedly installed at the front and rear ends of one side of the base, six mounting grooves are opened on the top of the support base, a spring is fixedly connected to the inner bottom of the mounting groove, a connecting block is fixedly connected to the top of the spring, and an extension column is fixedly connected to the center of the top of the connecting block.

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0007] The stamping die for the back panel of the TV set is designed with a protective cover, a gear, a motor, a rack, a slide rail and a sliding part. The motor drives the gear to rotate. Through the meshing of the gear and the rack, the rack drives the protective cover to move up and down as the gear rotates. During the stamping operation, the protective cover can quickly rise to the working area, effectively shielding the stamping area that may cause danger, thereby avoiding safety hazards such as cracking and fragment splashing, ensuring the safety of the operator, and further reducing the risk of industrial accidents. The design of the damping pad, the spring, the connecting block and the extension column is that during the stamping process, due to the large stamping force, the fixed die is often subjected to a strong impact. However, by introducing the combined design of the damping pad and the spring, this impact is significantly alleviated. The damping pad has good shock absorption performance and can quickly disperse and absorb energy when subjected to impact force, thereby reducing the impact force directly acting on the fixed die, and the elastic effect of the spring further plays a buffering effect. When the fixed die is impacted, the spring can undergo elastic deformation, converting part of the impact force into the potential energy of the spring for storage, thereby reducing the instantaneous impact on the fixed die.

[0017] The motor 6 is fixedly connected to an output shaft through the output end of its rear surface. The rear end of the output shaft passes through the base 1 and is fixedly connected to the center of the front surface of the gear 5. The motor 6 drives the gear 5 to rotate.

[0018] One side of the two sliding members 9 extends to the inside of the two slide rails 8 respectively and is slidably connected to the inner wall of the slide rails 8, thereby ensuring the stability of the protective cover 4 during vertical lifting.

[0019] The upper ends of the six extension columns 14 pass through the installation groove 11 and the outside of the damping pad 10 in sequence and are fixedly connected to the bottom of the fixed mold 3, which can evenly distribute the impact force. The impact force from the stamping can be evenly distributed to each point, avoiding local damage caused by excessive force on a single point, ensuring that the fixed mold 3 is evenly stressed, reducing stress concentration, and thus improving the overall stability of the fixed mold 3.

[0020] The opposite ends of the two sliders 16 extend into the interior of the two slide grooves 15 and are slidably connected to the inner walls of the slide grooves 15 , which stabilizes and limits the connection block 13 when it moves vertically.

[0021] Guide columns are fixedly installed at the four corners of the top of the base 1, a top plate is fixedly installed at the upper ends of the four guide columns, a cylinder is fixedly installed at the center of the top of the top plate, the cylinder is fixedly connected to a piston rod through the output end at the bottom, the lower end of the piston rod passes through the outside of the supporting top plate and is fixedly installed with a lifting plate, a movable mold is fixedly installed at the center of the bottom of the lifting plate, guide sleeves are slidably connected to the top positions of the surfaces of the four guide columns, and the outer walls of the four guide sleeves are respectively fixedly connected to the front end and rear end positions on both sides of the lifting plate, and the lifting plate is driven by the cylinder to drive the movable mold to rise and fall to achieve stamping.

[0022] The lower end of the base 1 is fixedly connected with a mounting plate, and a mounting hole is provided on the top of the mounting plate. Bolts penetrate the mounting hole to mount the entire mold.

[0023] The support seat 2 extends to the outside of the base 1, and the lower end of the protective cover 4 penetrates into the inside of the base 1. Slide grooves 15 are provided at the top positions on both sides of the installation groove 11, and sliders 16 are fixedly connected to the bottoms of both sides of the connecting block 13.

[0024] Working principle: First, the control motor 6 drives the gear 5 to mesh with the rack 7 to rotate. The rack 7 drives the protective cover 4 to move upward as the gear 5 rotates. The protective cover 4 drives the two sliding members 9 on the other side to slide upward inside the two slide rails 8 respectively. When the protective cover 4 covers the stamping working area, the cylinder can be controlled to move the movable mold downward and stamp the material. If flying chips are generated during the stamping process, they will be isolated by the protective cover 4. After the stamping is completed, the control motor 6 is reversed and drives the protective cover 4 to move downward into the base 1. During the stamping process, the fixed mold 3 is subjected to force, generating a downward impact force so that the six extension columns 14 at the bottom of the fixed mold 3 respectively drive the six connecting blocks 13 to compress the springs 12 in each mounting groove 11. Through the performance of the damping pad 10 and the spring 12, the impact force on the fixed mold 3 can be absorbed, thereby reducing the impact on the fixed mold 3.

[0025] In summary, the stamping die for the back panel of the television set is designed with a protective cover 4, a gear 5, a motor 6, a rack 7, a slide rail 8 and a sliding member 9. The motor 6 drives the gear 5 to rotate. Through the meshing of the gear 5 and the rack 7, the rack 7 drives the protective cover 4 to move up and down as the gear 5 rotates. During the stamping operation, the protective cover 4 can quickly rise to the working area, effectively shielding the stamping area that may be dangerous, thereby avoiding safety hazards such as cracking and splashing of debris, ensuring the safety of the operator, and further reducing the risk of industrial accidents. The damping pad 10, the spring 12, the connecting block 13 and the extension column 1 4, during the stamping process, due to the large stamping force, the fixed die 3 is often subjected to a strong impact. However, by introducing the combined design of the damping pad 10 and the spring 12, this impact is significantly alleviated. The damping pad 10 has good shock absorption performance and can quickly disperse and absorb energy when subjected to impact force, thereby reducing the impact force directly acting on the fixed die 3, and the elastic effect of the spring 12 further plays a buffering effect. When the fixed die 3 is impacted, the spring 12 can undergo elastic deformation, converting part of the impact force into potential energy of the spring 12 for storage, thereby reducing the instantaneous impact on the fixed die 3.
