[0030] In order to make the purpose, method scheme and advantages of the embodiments of the utility model clearer, the method scheme in the embodiments of the utility model is clearly and completely described. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings herein can be arranged and designed in various different configurations.

[0031] Example 1

[0032] like Figure 1-5 As shown, a bridge shell processing demoulding equipment comprises a lower die table 1, an upper top plate 2, and a guide column 3. The upper top plate 2 and the lower die table 1 are of the same size and their positions are fixed by the guide columns 3 at the four corners. The guide columns are made of stainless steel. The top surface of the lower die table 1 is fixed with a die 4 by bolts. A hydraulic cylinder 5 is installed on the top of the upper top plate 2. The output end of the hydraulic cylinder 5 is downward to drive the upper die table 6 to move. Guide cylinders are respectively installed at the four corners of the upper die table 6, so that the guide cylinders are connected by sliding up and down along the guide columns 3. A convex die 7 corresponding to the die 4 is arranged on the bottom surface of the upper die table 6. A stripping plate 8 is arranged above the lower die table 1. The stripping plate 8 is hinged to the lower die table 1 through swing plates 9 on the left and right sides. The number of swing plates 9 is at least two on the left and right, and the swing plates 9 are kept parallel during the rotation process to achieve The stripping plate 8 can always remain horizontal. A notch 10 corresponding to the die 4 is opened in the middle of the stripping plate 8. A support 11 is integrally formed inside the notch 10. The support 11 is set up to support the folding edge of the top of the workpiece. A servo motor 12 is installed on the back of the lower die table 1. The output end of the servo motor 12 is connected to a rotating shaft 13. At least one worm 14 is arranged on the rotating shaft 13. The worm 14 is located in the lower die table 1 and is driven by a worm gear 15. The worm gear 15 is coaxially connected to the bottom of the swing plate 9. At least one swing plate 9 is installed with a worm gear 15 to ensure that the servo motor 12 can drive the stripping plate 8 to move. The transmission mode of the worm gear 15 and the worm 14 is adopted to ensure that the stripping plate 8 can be self-locked when it is suspended in the air to prevent the stripping plate 8 from automatically falling due to gravity.

[0033] During the specific implementation process, the workpiece to be stamped is placed on the die 4 on the lower die table 1, and the hydraulic cylinder 5 drives the upper die table 6 to drive the punch 7 to move downward, so that the punch 7 stamps the workpiece to be stamped, and the shapes corresponding to the outer contours of the punch 7 and the die 4 are formed under the extrusion of the punch 7 and the die 4. Since the weight of the bridge shell processing workpiece is heavy, it is separated from the punch 7 by its own gravity, so that the workpiece remains in the die 4. After the punch 7 is raised to the highest point by the hydraulic cylinder 5, the servo motor 12 is started, the worm 14 drives the worm gear 15 to rotate, and the swing plate 9 is rotated by the worm gear 15. The rotation angle of the swing plate 9 is adjusted according to the servo motor 12, and the swing plate 9 drives the stripping plate 8 to rotate, so that the workpiece is separated from the hydraulic cylinder 5 directly below, reducing safety hazards. Secondly, when taking the workpiece, the obstruction of the guide column 3 is reduced, and the workpiece is taken more conveniently.

[0034] Example 2

[0035] In order to enable the servo motor 12 to start and automatically run immediately after the punch 7 reaches the top, the embodiment 1 is improved, such as Figure 6 As shown, in this embodiment, a travel switch 16 is provided on the side of the upper top plate 2, and a contact block 17 corresponding to the position of the travel switch 16 is bolted to the side of the upper mold platform 6, and the contact block 17 is made of rubber. The travel switch 16 is electrically connected to the servo motor 12.

[0036] During the specific implementation process, when the hydraulic cylinder 5 drives the upper die table 6 and the punch 7 to move to the top, the contact block 17 touches the travel switch 16, so that the servo motor 12 can be started immediately, so that the demolding process has continuity, and the operation mode of manually starting the servo motor 12 is reduced, saving production time.

[0037] Example 3

[0038] In order to prevent the workpiece from adhering to the punch 7 and to ensure that the workpiece does not fall or collide, improvements are made on the basis of Example 2, such as Figure 7 As shown, in this embodiment, the punch 7 includes a ejection groove 18, an ejection block 19, and a compression spring 20. A ejection groove 18 is opened at the bottom center of the punch 7, and a ejection block 19 is placed in the ejection groove 18. The lower surface contour of the ejection block 19 is connected to the outer contour of the punch 7, and the top of the ejection block 19 is supported by the compression spring 20.

[0039] During the specific implementation process, the maximum distance that the ejection block 19 protrudes outside the punch 7 does not exceed 2 cm, and the gap between the ejection block 19 and the ejection groove 18 is controlled within 50 wires to ensure that the inner contour surface of the workpiece is smooth. Secondly, the pressure range of the compression spring 20 is 50N-100N. Since the ejection block 19 is acted upon by the compression spring 20, the punch 7 can instantly fix the formed workpiece when it is just lifted up and separate from the punch 7, thereby avoiding the upper punch 7 from sticking to the formed workpiece and falling off.

[0040] Example 4

[0041] In order to make the notch 10 correspond to the die 4 after the stripper plate 8 is reset with the lower die table 1 to avoid the scrapping of the workpiece, improvements are made on the basis of embodiment 3, such as Figure 8 As shown, in this embodiment, the upper die table 6 also includes a positioning column 21, the height of the bottom of the positioning column 21 is lower than the height of the bottom of the punch 7, there are at least two positioning columns 21, and an emergency stop switch 22 is installed at the bottom, and a positioning groove 23 corresponding to the upper and lower positions of the positioning column 21 is opened on the stripping plate 8, and the emergency stop switch 22 is electrically connected to the hydraulic cylinder 5.

[0042] During the specific implementation process, if the stripping plate 8 and the lower die table 1 are in the same position after resetting, the positioning column 21 can be inserted into the positioning groove 23 during the falling process. At this time, the emergency stop switch 22 will not touch the stripping plate 8, allowing the hydraulic cylinder 5 to operate normally; if the stripping plate 8 and the lower die table 1 deviate from the position after resetting, the positioning column 21 cannot correspond to the positioning groove 23 during the falling process, causing the emergency stop switch 22 to touch the upper surface of the stripping plate 8 and press, causing the hydraulic cylinder 5 to stop suddenly, thereby avoiding the mismatch between the position of the notch 10 and the die 4, causing the workpiece to be scrapped.

[0043] Example 5

[0044] In order to better demould the concave mold 4 and the convex mold 7 and reduce the process of manually spraying the demoulding agent, improvements are made on the basis of Example 4, such as Figure 9-10 As shown, in this embodiment, a jet pipe 24 is installed behind the stripping plate 8, and the jet pipe 24 is made of a hard water pipe material, such as stainless steel or hard plastic. A nozzle 25 is installed at the top end of the jet pipe 24, and a water inlet 26 is installed at the bottom. The water inlet 26 is externally connected to a solenoid valve, and a touch switch 27 is provided on the front side of the lower mold platform 1. The nozzle 25 is an upper and lower double nozzle, and the sprayed liquid is a demoulding agent. The touch switch 27 is electrically connected to the solenoid valve externally connected to the water inlet 26.

[0045] During the specific implementation process, when the demoulding plate 8 completes the feeding, it will touch the touch switch 27 on the lower mold platform 1. The touch switch controls the solenoid valve, so that the demoulding agent is sprayed out from the nozzle 25 from the jet pipe 24 up and down. The demoulding agent adheres to the die 4 and the punch 7, reducing the manual spraying process, realizing the automation of spraying the demoulding agent, and avoiding the adhesion of the workpiece to the die 4 or the punch 7.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
