DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] In one embodiment, Figure 1-Figure 5 As shown, a watch strap ear position and ear hole folding and fitting device comprises a lower die base 5 and an upper die base 12, the surface of the lower die base 5 is fixedly provided with a lower die frame 2, the surface of the upper die base 12 is slidably provided with an upper die core 15, the lower die frame 2 and the upper die core 15 are used together to fold the watch strap, the surface of the lower die frame 2 is provided with a lower die core 1 for placing the watch strap, the bottom surface of the lower die core 1 is fixedly provided with a first spring 7, the other end of the first spring 7 is fixedly connected to the inner bottom wall of the lower die frame 2, when in use, the operator puts the leather material of the product to be folded into the lower die core 1, and the first spring 7 inside the lower die core 1 can move up and down.

[0031] In one embodiment, Figure 1-Figure 5 As shown, the top end of the lower mold core 1 is slidably provided with a push block 4 for folding through a fifth spring 18, and the two ends of the fifth spring 18 are respectively fixedly connected to the side walls of the lower mold core 1 and the side walls of the push block 4, and the top end of the upper mold base 12 is fixedly provided with an upper mold pressing plate 10, and the upper mold pressing plate 10 is used in conjunction with the push block 4. When the push block 4 is connected to it and pressed down, it is squeezed to the left by the upper mold pressing plate 10. At the same time, when the product to be folded is forced to move downward together with the lower mold core 1, the leather material that exceeds the position of the lower mold core 1 is bent to the left due to the downward pressure of the steel needle and the leftward force of the push block 4.

[0032] In one embodiment, Figure 3 and Figure 4 As shown, a steel needle slot 6 is fixedly provided on the side of the lower mold core 1, and a slide groove 16 is opened on the side wall of the steel needle slot 6. A fourth spring 17 is fixedly provided on the inner wall of the slide groove 16. The other end of the fourth spring 17 is fixedly connected to the ball 3. The ball 3 is slidably arranged on the inner wall of the slide groove 16. When the steel needle is pressed downward, the ball 3 is forced to give way to both sides. After the steel needle is pressed to the bottom, the ball 3 bounces back under the action of the fourth spring 17.

[0033] In one embodiment, Figure 1 As shown, the upper mold core 15 is slidably sleeved on the upper surface of the upper mold base 12, and a third spring 13 is fixedly provided on the bottom surface of the upper mold base 12. The other end of the third spring 13 is fixedly connected to the inner bottom wall of the upper mold core 15. A pressing plate 14 is fixedly provided on the upper surface of the upper mold base 12. The side of the pressing plate 14 is slidably connected to the side of the upper mold core 15. When the product to be bent and the lower mold core 1 are pressed to the bottom, the upper mold core 15 is forced to move upward to be flush with the pressing plate 14. The pressing plate 14 is a fixed component. At this time, the pressing plate 14 applies pressure to the leather material of the product to be bent leftward to make it firmly bonded.

[0034] In one embodiment, Figure 2 As shown, the upper surface of the upper mold base 12 is fixedly provided with positioning pins 8 for positioning guidance. The positioning pins 8 are symmetrically arranged at the four corners of the upper mold core 15. The steel needle slot 6 is a conical shape with a larger upper end and a smaller lower end. The steel needle slot 6 is used in conjunction with the positioning hole on the surface of the lower mold core 1, and the docking of the lower mold base 5 and the upper mold base 12 is achieved through the positioning pins 8.

[0035] In one embodiment, Figure 2 As shown, the inner wall of the upper mold base 12 is slidably provided with a steel needle presser foot 9 used in conjunction with the steel needle slot 6, and the bottom surface of the steel needle presser foot 9 is fixedly connected with a second spring 11, and the other end of the second spring 11 is fixedly connected to the inner bottom wall of the upper mold base 12, and the upper surface of the steel needle presser foot 9 is provided with a slot used in conjunction with the steel needle. When the machine is started to press the upper mold down, the upper mold core 15 presses the product to be bent and the steel needle presser foot 9 presses the steel needle downward synchronously, and the bottom surface of the steel needle presser foot 9 is fixedly connected with the second spring 11 and can move up and down.

[0036] In one embodiment, Figure 1 As shown, the inner bottom wall of the lower mold core 1 is fixedly provided with an anti-skid protective pad, which can prevent the strap from sliding and deflecting during use.

[0037] The above embodiment discloses a watch strap ear position and ear hole folding and fitting device, wherein when in use, the operator places the leather material of the product to be folded into the lower mold core 1, and the first spring 7 inside the lower mold core 1 can move up and down, and a steel needle with the same diameter as the ear hole is placed on the ball 3 in the steel needle slot 6, and the fourth spring 17 connected to the ball 3 can move left and right. When the upper mold of the machine is started and pressed down, the upper mold core 15 presses the product to be bent, and the steel needle presser foot 9 presses the steel needle downward synchronously. The bottom surface of the steel needle presser foot 9 is fixedly connected with a second spring 11 which can move up and down. When the steel needle is pressed down, the ball 3 is forced to make way to both sides. After the steel needle is pressed to the bottom, the ball 3 rebounds. The fifth spring 18 connected to the lower mold push block 4 can move left and right. When pressed down from above, it is squeezed to the left by the upper mold pressing plate 10. At the same time, when the product to be bent and the lower mold core 1 are forced to move downward, the leather material that exceeds the part of the lower mold core 1 is bent to the left by the downward pressure of the steel needle and the left force of the push block 4. The second spring 11 connected inside the upper mold core 15 can move up and down. When the product to be bent and the lower mold core 1 are pressed to the bottom, the upper mold core 15 is forced to move upward to be flush with the pressing plate 14. The pressing plate 14 is a fixed component. At this time, the pressing plate 14 applies pressure to the leather material of the product to be bent to the left to make it firmly bonded.
