Description

Technical Field

[0001] This utility model relates to the field of watch case manufacturing, specifically to a stamping equipment for watch case manufacturing. Background Technology

[0002] Pressure gauges are widely used instruments in industrial measuring equipment, and the gauge case is one of the most important components. The quality of the gauge case directly affects the performance and reliability of the pressure gauge. Therefore, stamping equipment is the key to manufacturing high-quality pressure gauge cases.

[0003] A Chinese patent discloses a stamping equipment for the production of pressure gauge housings (authorization announcement number CN 220880094U). This patented technology "adopts enhanced rigidity technology to improve the manufacturing precision and stability of pressure gauge housings. This technology typically employs high-hardness mold materials and frame-type structural designs to increase the rigidity and vibration resistance of the equipment. Furthermore, by changing different types of molds, it can produce various pressure gauge housings of different specifications and shapes on the same equipment, thereby improving the equipment's flexibility and reducing production cycle and costs." This solves the problem that "some pressure gauges require housings of various specifications and shapes, which necessitates frequent mold changes during production, resulting in significant time and efficiency losses." However, the patent still has the following problems:

[0004] The stamping process in this patent is an open-air operation. When a stamping error occurs, the flying debris can easily cause injury to people, reducing the safety of the operation. In addition, the mold is prone to wear and tear, and it is inconvenient to disassemble and replace it. Utility Model Content

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] Please see Figures 1-5 This embodiment provides a stamping device for watch case production, including a base 1 and a working cavity 2. The working cavity 2 is installed on the upper surface of the base 1. An adjusting cylinder 11 is embedded in the top of the working cavity 2. An upper die holder 12 is installed at the output end of the adjusting cylinder 11. A lower die cavity 13 is arranged below the upper die holder 12. A fixed seat 14 is arranged above the upper die holder 12. Connecting seats 15 are symmetrically installed on the left and right sides of the front end face of the fixed seat 14. A cover 16 is installed on the front end face of the connecting seat 15. Positioning seats 17 are symmetrically installed on the left and right sides of the upper surface of the base 1. The inner end of the positioning seat 17 is slidably connected to the upper surface of the base 1. The working chamber 2 is equipped with a cover door 16 and a control panel 27 is installed on the left end face of the working chamber 2. The regulating cylinder 11 is electrically connected to the control panel 27. The control panel 27 is programmed with a PLC to control the operation of each device. During operation, the regulating cylinder 11 is activated, which drives the upper mold base 12 to move downward, thereby stamping and forming the watch case. During the downward movement, the cover door 16 moves downward, thereby sealing and protecting the working chamber 2 to prevent the watch case from breaking due to processing errors, which could cause debris to fly and injure personnel in front of the working chamber 2, thus ensuring the safety of the operation.

[0021] The upper mold base 12 is installed at the output end of the regulating cylinder 11 by means of a first clamp 18. The left and right side walls of the working cavity 2 are fitted with a fixing frame 19 by means of sliding fit. The fixing frame 19 and the upper mold base 12 are screwed together by a first bolt 21. During operation, the fixing frame 19 structure is used to ensure the stability of the upper mold base 12 moving up and down. The first bolt 21 structure is used to facilitate the disassembly and replacement of the upper mold base 12.

[0022] The bottom of the lower mold cavity 13 is equipped with a positioning block 22 by means of insertion. The left and right side walls of the lower mold cavity 13 are screwed to the bottom of the working cavity 2 by the second bolt 23. During operation, the positioning block 22 positions the lower mold cavity 13. The structure of the second bolt 23 makes it easy to disassemble and replace the lower mold cavity 13.

[0023] A rubber pad 24 is installed on the upper surface of the base 1, and a cover 16 is arranged above the rubber pad 24. During operation, the structure of the rubber pad 24 is used to provide shock absorption and protection when the cover 16 moves down.

[0024] The upper surface of the working chamber 2 is symmetrically fitted with first telescopic rods 25. The output end of the first telescopic rod 25 is installed on the upper surface of the fixed seat 14. A second telescopic rod 26 is arranged in front of the first telescopic rod 25. The output end of the second telescopic rod 26 is installed on the upper surface of the connecting seat 15. During operation, the first telescopic rod 25 acts as a pressure divider on the output end of the adjusting cylinder 11, and the second telescopic rod 26 acts as a connection to the connecting seat 15, ensuring the stability of the cover door 16 moving up and down, and further ensuring the overall stability of the device.

[0025] During operation, the regulating cylinder 11 is activated, causing the upper mold base 12 to move downward, thereby stamping and forming the watch case. During the downward movement, the cover 16 moves down, thereby sealing and protecting the working chamber 2 to prevent the watch case from breaking due to processing errors, which could cause debris to fly and injure personnel in front of the working chamber 2, thus ensuring the safety of the operation.
