Description

Technical Field

[0001] This utility model relates to the field of titanium alloy watch case fixture technology, specifically a punching structure that works with a titanium alloy watch case fixture. Background Technology

[0002] In the watchmaking industry, titanium alloys are considered an ideal material for high-end watch cases due to their excellent strength, corrosion resistance, and lightweight properties. Currently, the processing of titanium alloy watch cases typically involves stamping titanium alloy sheets into watch case blanks of specific shapes using stamping equipment, followed by subsequent precision processing. However, in existing titanium alloy watch case stamping processes, the feeding of titanium alloy sheets still largely relies on manual operation. This traditional feeding method presents many problems that urgently need to be solved, severely restricting production efficiency and product quality, and also posing significant safety hazards.

[0003] First, manual feeding makes it difficult to guarantee feeding accuracy, which can easily lead to positioning deviations in titanium alloy sheets during the punching process, thereby increasing waste. This not only significantly increases the waste rate of raw materials and raises production costs, but also requires workers to perform additional sorting and processing of waste, further reducing overall production efficiency. Actual production data shows that the waste rate caused by inaccurate manual feeding accounts for more than 60% of the total waste, causing huge economic losses to enterprises.

[0004] Secondly, there are serious safety risks in the manual feeding process. When the punching equipment is working, its punching mechanism will reciprocate at high speed. The operator needs to hold the titanium alloy sheet and feed it to the punching area. During this process, if the operator is not focused, makes a mistake, or the punching equipment malfunctions, the operator's hand is easily injured by the punching mechanism, causing a safety accident. In recent years, there have been frequent safety accidents in the industry caused by manual feeding, such as hand cuts and crush injuries. This not only threatens the personal safety of the operators, but also has a negative impact on the production order and social reputation of enterprises. Utility Model Content

[0005] The purpose of this invention is to provide a punching structure that works with a titanium alloy watch case fixture to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a punching structure for use with a titanium alloy watch case fixture, comprising a support base and a lower die. The lower die is detachably mounted at the center of the top of the support base. Grooves are symmetrically fixed on both sides of the lower die at the top of the support base. A sliding groove is formed inside the groove, and a slider is slidably connected inside the sliding groove. A support block is fixed at the top of the slider. The support block is U-shaped. A rotating roller is rotatably connected to one side of the inner wall of the support block, and a ball bearing is rotatably connected to the other side of the inner wall of the support base. The ball bearing is partially exposed. A snap-fit ​​assembly is provided on the outer side of the support block.

[0007] Preferably, the distance between the rotating roller and the ball is matched with the titanium alloy plate of the watch case.

[0008] Preferably, the rotating roller is rotatably connected to the inner side of the support block via a shaft, and the end of the shaft passing through the support block is connected to a disc, and the outer wall of the disc has an arc-shaped groove.

[0009] Preferably, the support block and the slider are connected by a vertical rod.

[0010] Preferably, the snap-fit ​​assembly includes a sleeve, which is fixed to the outer wall of the vertical rod between the support block and the slider. A top rod is inserted into the top end of the sleeve, and a spring is sleeved on the outer wall of the top rod. A snap-fit ​​block is fixed to the top end of the top rod.

[0011] Preferably, the shape of the card block matches the groove formed on the outer wall of the disk.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The snap-fit ​​assembly uses a sleeve, push rod, spring, and snap-fit ​​block to work together. An arc-shaped groove is opened on the outer wall of the turntable. When the turntable drives the rotating roller to rotate and feed the material, the groove will push the snap-fit ​​block to move down and squeeze the spring. After the turntable rotates one revolution, the titanium alloy plate moves to the preset punching position. The spring reaction force causes the snap-fit ​​block to move up and snap into the groove. This not only realizes the turntable snap-fit ​​positioning, but also intuitively indicates to the operator that the plate has moved into place through the snap-fit ​​action, avoiding the error of manually judging the feeding position. There is no need to set up additional sensors or other complex devices, which reduces equipment costs and allows operators to quickly grasp the feeding progress, improving the convenience of operation. The support block and the slider are connected by a vertical rod. The slider can be adjusted along the groove of the slot plate. After adjustment, the slider is fixed by pressing it through the slot plate with a fixing screw. The operation is simple and efficient. The diameter of the turntable is designed according to the operation requirements, which makes it convenient for the operator to manually rotate it to move the titanium alloy plate. There is no need to rely on a complex drive mechanism, which simplifies the operation process, lowers the threshold for equipment operation, and improves processing efficiency. The combination of the rotating roller and the ball bearing not only enables smooth feeding of the sheet material, but also reduces the hard friction between the sheet material and the supporting components, avoiding scratches, indentations and other damage to the sheet material surface, and reducing the loss rate of titanium alloy sheet material. Especially considering the high cost of titanium alloy material, it can effectively control raw material waste and improve production economy. Attached Figure Description

[0016] Please see Figure 1-5This utility model provides a punching structure technical solution for a titanium alloy watch case fixture: a punching structure for a titanium alloy watch case fixture includes a support base 1 and a lower die 2. The lower die 2 is detachably installed at the top center of the support base 1. The lower die 2 is a key component that directly contacts the titanium alloy watch case sheet and realizes punching and forming. Groove plates 3 are symmetrically fixed on both sides of the top of the support base 1 at the lower die 2. The groove plates 3 have internal sliding grooves. Fixing members are provided on the outer wall of the groove plates 3 to press and fix the slider 5. The cross-section of the groove is rectangular, and the width and depth of the groove are matched according to the size of the slider 4 to ensure that the slider 4 can slide smoothly inside the groove. The slider 5 is slidably connected inside the groove, and the two sides of the slider 4 are tightly fitted to the inner wall of the groove, ensuring the smooth sliding of the slider 4. It can also effectively prevent the slider 4 from shaking during the sliding process. The top of the slider 5 is fixed with a support block 5. The support block 5 is U-shaped. A rotating roller 6 is rotatably connected to one side of the inner wall of the support block 5. A ball bearing 7 is rotatably connected to the other side of the inner wall of the support block 5. The ball bearing 7 is partially exposed. The ball bearing 7 is used to support the titanium alloy plate. The cooperation with the rotating roller 6 can ensure the smooth sliding of the titanium alloy plate. A snap-fit ​​component is provided on the outer side of the support block 5. The distance between the rotating roller 6 and the ball bearing 7 matches the titanium alloy plate of the watch case. The rotating roller 6 is rotatably connected to the inner side of the support block 5 through a shaft. The shaft 6 passes through the end of the support block 5 and is connected to a disc 8. The diameter of the disc 8 is designed according to the operation requirements, so that the operator can control the rotation of the rotating roller 6 by rotating the disc 8. The outer wall of the disc 8 is provided with an arc-shaped groove. The support block 5 and the slider 4 are connected by a vertical rod.

[0017] The snap-fit ​​assembly includes a sleeve 9. The length of the sleeve 9 is designed according to the stroke requirements of the push rod 10 to ensure that the push rod 10 can move smoothly up and down inside the sleeve 9. The sleeve 9 is fixed to the outer wall of the vertical rod between the support block 5 and the slider 4. The push rod 10 is inserted into the top of the sleeve 9.

The shape of the snap-fit ​​block 12 matches the groove opened on the outer wall of the disc 8.

[0018] Working principle: When a punching structure for a titanium alloy watch case fixture is first used, as the titanium alloy plate enters the upper part of the lower mold 2 during feeding, the user first adjusts the support block 5 inward to match the width of the titanium alloy plate. Then, the titanium alloy plate is inserted between the rotating roller 6 and the ball bearing 7. After the support block 5 is adjusted to the appropriate position, it is fixed by pressing the slider 4 through the slot plate 3 with the fixing screw. Then, the user rotates the turntable 8. When the turntable 8 rotates, the titanium alloy plate moves parallel through the guide roller 6. When the turntable 8 rotates, the locking block 12 is pushed downward through the arc groove on the outer wall. When pushed, the locking block 12 drives the push rod 10 to move into the sleeve 9 and presses the spring 11. Then, when the turntable 8 rotates one revolution and the arc groove coincides with the locking block 12, the reaction force of the spring 11 pushes the locking block 12 upward and inserts it into the inside of the turntable 8 to achieve locking and prompt the operator to move the titanium alloy plate into place. Then, the titanium alloy plate is punched by the punching equipment above the lower mold 2.
