Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a stamping mold for an air compressor switch cover. Background Technology

[0002] The top cover of the air compressor switch is a metal plate with several mounting holes. Its production and processing are generally completed by stamping with a stamping die. When processing the top cover of the air compressor, the existing stamping die generally requires two processing steps: punching and blanking. First, the punching die on the moving die and the punching hole on the stationary die punch the mounting holes on the material strip. Then, the material strip is moved and the blanking die on the moving die and the blanking hole on the stationary die punches the top cover of the air compressor switch off the material strip. This type of stamping die is not only large in size and requires a large press, which increases the cost, but also the deformation of the material during the subsequent blanking process will cause the size fluctuation of the mounting holes formed by the previous punching, thus affecting the quality of the finished product.

[0003] To address the aforementioned problems, this utility model provides improvements. Utility Model Content

[0022] The following will refer to the appendix in the embodiments of this utility model. Figure 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] As shown in the figure, a stamping die for an air compressor switch cover includes a mounting plate 1, a stationary template 2, and a movable template 3. A first guide post 4 is fixedly mounted on the stationary template 2. The movable template 3 passes through the first guide post 4 and slides in cooperation with the stationary template 2. A cutting edge plate 5 is fixedly mounted on the stationary template 2. The cutting edge plate 5 has a cutting opening 51. A support plate 6 is provided on the stationary template 2, extending into the cutting opening 51 and with its upper end face flush with the upper end face of the cutting edge plate 5. An annular cutting ring hole 7 is formed between the support plate 6 and the inner wall of the cutting opening 51. A plurality of longitudinally penetrating forming holes 61 are provided on the support plate 6. The stationary template 2 has forming holes 61 that correspond to the forming holes 61. The corresponding waste outlet 201 has a material support ring 9 slidably mounted on the stationary template 2 via several second guide posts 8. The second guide posts 8 are fixedly mounted on the stationary template, and the material support ring 9 passes through the second guide posts 8. A first spring 10 is sleeved on the second guide posts 8 between the stationary template 2 and the material support ring 9. Under the action of the first spring 10, the material support ring 9 passes into the cutting ring hole 7, and the upper end face of the material support ring 9 is flush with the upper end face of the cutting edge plate 5. The moving template 3 is fixedly mounted with a cutting blade 11 that matches and aligns with the cutting ring hole 7 and several punching blades 12 that match and align with the forming hole 61. The inner wall contour of the cutting blade 11 and the outer wall contour of the support plate 6 are aligned with the forming hole 61. Figure 1 The outer contour of the air compressor switch cover shown is consistent with that of the outer contour of the punching head 12 and the inner contour of the mounting hole of the air compressor switch cover.

[0024] In the above structure, the metal strip is intermittently passed between the blade plate 5 and the cutting head 11 by the conveying mechanism. The conveying mechanism for the metal strip is existing technology and will not be described in detail here. The metal strip is then punched with blanks as shown in the description. Figure 1 When the air compressor switch cover is installed, the press drives the moving template 3, which in turn moves the cutting head 11 and the punching head 12 toward the metal strip placed on the cutting plate 5. After the cutting head 11 and the punching head 12 contact the metal strip, they respectively cooperate with the cutting ring hole 7 and the forming hole 61 to punch out the outer contour and mounting hole of the air compressor switch cover. The annular waste generated by the cutting head 11 in cooperation with the cutting ring hole 7 is pressed into the cutting ring hole 7 along with the cutting head 11 and presses down the material support ring 9 to slide on the second guide post 8, thus compressing the first spring 10. After the cutting head 11 returns to its original position, the restoring force of the first spring 10 drives the material support ring 9 to move the annular waste upward from the cutting ring hole. The circular scrap generated by the punching head 12 and forming hole 61 falls through the forming port and the waste discharge port 201 after leaving the 7-hole. After the metal material strip is reset, the annular scrap and the air compressor switch cover are retained on the upper surface of the material support ring 9 and the support plate 6, respectively. The forming stamping of the air compressor switch cover can be completed by removing the annular scrap and the air compressor switch cover. The stamping die with the above structure and working method can stamp the outer contour and mounting hole of the air compressor switch cover in one process, ensuring the accuracy during forming and reducing the volume of the stamping die. This allows the stamping die to be applied to presses of different specifications, reducing the manufacturer's cost.

[0025] Furthermore, based on the above structure, a stripper plate 13 is slidably disposed inside the cutting head 11 via several third guide posts 14. The T-shaped third guide posts 14 pass through the moving template 3 and are fixedly connected to the stripper plate 13 inside the cutting head 11. A second spring 15 is sleeved on the third guide post 14, located between the stationary template 2 and the stripper plate 13. The lower end face of the stripper plate 13 is flush with the lower end faces of the cutting head 11 and the punching head 12. When the cutting head 11 and the punching head 12 are forming the air compressor switch cover, the stripper plate 13 moves downwards with the moving template 3, contacting the cutting head 11 and the punching head 12. The punching head 12 moves downward and presses against the metal strip. During the cutting head 11 and punching head 12 punching, the stripper plate 13 is always pressed against the metal strip and the third guide post 14 slides on the moving mold and compresses the second spring 15. The stripper plate 13 presses against the metal strip to reduce the deformation of the metal strip during punching and ensure the forming accuracy. After the cutting head 11 and punching head 12 are reset, the stripper plate 13 is reset under the action of the second spring 15 and is always pressed against the air compressor switch cover. This allows the air compressor switch cover to exit from the cutting head 11 and the punching head 12 and remain on the support plate 6, which facilitates subsequent material unloading.

[0026] Furthermore, based on the above structure, a pressure plate 16 is slidably disposed on the moving template 3 between the moving template 3 and the stationary template 2 via several fourth guide posts 17. The fourth guide posts 17, which are T-shaped rods, pass through the moving template 3 and are fixedly connected to the pressure plate 16. A third spring 18 is sleeved on the fourth guide post 17 between the moving template 3 and the pressure plate 16. The lower end face of the pressure plate 16 is flush with the lower end face of the cutting head 11. When the cutting head 11 and the punching head 12 are forming and stamping the air compressor switch cover, the pressure plate 16 is always pressed against the metal material strip under the action of the third spring 18, suppressing the flow of the metal material strip during forming and stamping, thereby ensuring the forming accuracy.

[0027] In addition, based on the above structure, a positioning protrusion 161 is formed on the lower end surface of the pressure plate 16, which surrounds the cutting head 11. The cross-section of the positioning protrusion 161 is V-shaped. When the pressure plate 16 is pressed onto the metal material strip, the positioning protrusion 161 is inserted into the metal material strip. The positioning protrusion 161 further suppresses the flow of the metal material strip, thereby ensuring the forming accuracy.

[0028] In addition, based on the above structure, the mounting plate 1 is provided with a feeding cylinder 19 located on one side of the material conveying direction. The output shaft of the feeding cylinder 19 faces the knife edge plate 5 and a feeding push plate 20 is fixedly connected to the output shaft of the feeding cylinder 19. After the forming and stamping of the air compressor switch cover is completed, the feeding cylinder 19 drives the feeding push plate 20 to move towards the annular waste material and the air compressor switch cover retained on the material support ring 9 and the support plate 6, thereby pushing the annular waste material and the air compressor switch cover to be unloaded from the knife edge plate 5, realizing the discharge of the annular waste material and the unloading of the air compressor switch cover, thereby improving the production efficiency.

[0029] In addition, based on the above structure, the mounting plate 1 is provided with a feeding rack 21 located on the other side of the material conveying direction. The feeding rack 21 is provided with a receiving plate 211 flush with the upper end face of the blade plate 5. The receiving plate 211 has a feeding port 212 for the air compressor switch cover to pass through. The feeding rack 21 is inclinedly provided with a first guide plate 213 located below the feeding port 212 and a second guide plate 214 connected to the receiving plate 211. The annular waste material pushed by the feeding push plate 20 and the air compressor switch cover are separated. After the cutting edge plate 5 slides onto the receiving plate 211, the air compressor switch cover, under its own weight, falls through the discharge port 212 onto the first guide plate 213 and down along the first guide plate 213, thus unloading the air compressor switch cover. The annular waste material remaining on the receiving plate 211 is pushed by the next annular waste material sliding onto the receiving plate 211 and slides onto the second guide plate 214, thus discharging the annular waste material. This achieves the separation and unloading of the annular waste material and the air compressor cover switch, improving production efficiency.

[0030] In addition, based on the above structure, a top plate 22 is fixedly installed on the moving template 3 above the discharge port 212. When the moving template 3 slides down to form the air compressor switch cover, the top plate 22 moves down with the moving template 3 and passes into the discharge port 212, pushing the air compressor switch cover in the annular waste material downwards, ensuring that the air compressor switch cover is separated from the annular waste material and thus realizing the discharge.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
