Description

Technical Field

[0001] This application relates to the field of mechanical manufacturing technology, and in particular to a mechanical manufacturing protection device. Background Technology

[0002] With the continuous development of society and the continuous progress of science and technology, the machinery manufacturing industry has also developed rapidly. Machinery manufacturing refers to the industrial sector engaged in the production of various power machinery, lifting and transportation machinery, agricultural machinery, metallurgical and mining machinery, chemical machinery, textile machinery, machine tools, tools, instruments, meters and other mechanical equipment. The machinery manufacturing industry provides technical equipment for the entire national economy, and its development level is one of the main indicators of the country's industrialization level.

[0003] A search revealed that utility model patent CN219520311U discloses a protective device for mechanical manufacturing, comprising: a mounting plate; four sliding rods fixedly installed around the top of the mounting plate, a mounting frame fixedly installed on the top of the sliding rods, and a stamping device fixedly installed in the center of the top of the mounting frame; a protective device disposed inside the mounting frame, the protective device including a protective box. This utility model releases the restriction on the protective device by pulling out the limiting device, thereby allowing the protective device to move and cover the stamping area, preventing parts from bursting out during stamping. After stamping, the protective device can be moved upwards and the limiting device can be used to expose the stamping area. This protects operators from accidental dangers during stamping and improves the protection effect for operators during operation.

[0004] However, this patent has certain shortcomings in its use. For example, when using the device, the limit rod needs to be manually pulled away from the limit hole, and then the pull rod of the protective device needs to be manually held to adjust the protective device. This makes the operation inconvenient, resulting in a decrease in stamping speed and thus a reduction in efficiency. Utility Model Content

[0023] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0024] This application discloses a mechanical manufacturing protection device, including a base 1, a support frame 2 on the top of the base 1, a protective cover 3 on the top of the base 1 at the edge of the support frame 2, two symmetrical mounting frames 4 on the side walls at both ends of the support frame 2, a rotating mechanism that drives the protective cover 3 to move up and down inside the two mounting frames 4, a hydraulic cylinder 5 on the top of the support frame 2, the output end of the hydraulic cylinder 5 passing through a through hole opened on the top of the support frame 2 and connected to a pressure plate 6 at the bottom.

[0025] refer to Figure 1 and Figure 2The rotating mechanism includes two identical lead screws 7. One end of each lead screw 7 is connected to a bearing seat at the bottom of the mounting frame 4. The other end of each lead screw 7 passes through a through hole at the top of the mounting frame 4 and is connected to a synchronous pulley 8. A synchronous belt 9 is fitted between the two synchronous pulleys 8. The synchronous belt 9 passes through through slots on the side walls at both ends of the support frame 2 near the top of the mounting frame 4. A horizontal plate is connected to the bottom of the synchronous belt 9 between the inner walls at both ends of the support frame 2. A mounting seat is provided at the top of one of the synchronous pulleys 8 on one side wall of the support frame 2. A motor 10 is provided on the top of the mounting seat. The output end of the motor 10 passes through a through hole on the mounting seat and is connected to the synchronous pulley 8. Movable seats 11 are also fitted onto the two lead screws 7. The movable seat 11 is installed inside the mounting frame 4. One end of the movable seat 11 is also provided with a connecting block, and the other end of the connecting block is connected to the inner wall of the protective cover 3. More specifically, when the protective cover 3 is adjusted, the drive motor 10 drives one of the synchronous pulleys 8 to rotate, which drives the other synchronous pulley 8 to rotate simultaneously through the synchronous belt 9. This causes the lead screw 7 connected to the bottom of the two synchronous pulleys 8 to rotate, thereby driving the two movable seats 11 to slide up and down along the mounting frame 4 to adjust the position of the protective cover 3. This allows the operator to move the protective cover 3 to the stamping area during stamping, preventing parts from popping out during stamping and improving protection. At the same time, it makes it easier for the operator to move the protective cover 3 upward to place the next part for stamping, making the operation more convenient and improving work efficiency.

[0026] refer to Figure 3 and Figure 4 The bottom of the pressure plate 6 is provided with an upper mold 12, and the top of the base 1 is located at the bottom of the upper mold 12, where a lower mold 13 is provided. Four buffer components are also provided between the bottom of the pressure plate 6 and the base 1. Each buffer component includes four sleeves 14, inside which a compression spring 15 is installed. One end of the compression spring 15 is connected to the inner top surface of the sleeve 14, and the other end of the compression spring 15 is connected to a pressure block 16. The four pressure blocks 16 are slidably installed inside the sleeves 14. A fixing rod 17 is connected to the bottom of each pressure block 16, and one end of the fixing rod 17 passes through the bottom of the sleeve 14. The through hole is connected to the top of the base 1. More specifically, when stamping, the driving hydraulic cylinder 5 drives the pressure plate 6 to move downward, so that the upper mold 12 moves up and down to the top of the lower mold 13. At the same time, the four fixing rods 17 set at the top of the base 1 slide along the four sleeves 14 set at the bottom of the pressure plate 6, and drive the pressure block 16 to squeeze the compression spring 15 set inside. Under the action of the compression spring 15, the pressure plate 6 is buffered to a certain extent, so that the upper mold 12 and the lower mold 13 are buffered during stamping, preventing the mold from being damaged due to long-term stamping.

[0027] The implementation principle of the mechanical manufacturing protection device in this application embodiment is as follows: In use, the part is placed on the top of the lower mold 13, and the drive motor 10 is used to make one of the synchronous pulleys 8 rotate, which drives the other synchronous pulley 8 to rotate through the synchronous belt 9. This causes the lead screw 7 connected to the bottom of the two synchronous pulleys 8 to rotate in the mounting frame 4, and at the same time, it drives the two movable seats 11 to slide along the mounting frame 4, so that the protective cover 3 connected at one end moves the stamping area. Then, the hydraulic cylinder 5 is driven to move the pressure plate 6 downward, so that the upper mold 12 stamps the part placed on the top of the lower mold 13. During the stamping process, the pressure plate 6 drives the four sleeves 14 set at the bottom to move downward, so that the four fixed rods 17 set at the top of the base 1 slide along the sleeves 14, and drive the pressure block 16 to squeeze the compression spring 15. This allows the compression spring 15 to provide a certain buffer for the pressure plate 6, so that the upper mold 12 and the lower mold 13 have a certain buffering effect when stamping, preventing the mold from being damaged due to long-term stamping.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
