Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, specifically a vacuum forming punching and cutting device. Background Technology

[0002] Vacuum forming is a thermoforming method for thermoplastic materials. It involves clamping sheet or plate-shaped material onto the frame of a vacuum forming machine. After heating and softening, a vacuum pump creates a vacuum between the mold and the heated sheet material through air passages on the mold edge. This creates a pressure difference, causing the sheet material to adhere to the mold. After a short cooling time, air is blown into the mold to release the formed plastic product. Currently, after vacuum-formed parts are removed from the mold, they still need to be punched and trimmed to their desired shape.

[0003] Existing punching and cutting devices for vacuum-formed parts suffer from slight positional shifts during punching and cutting due to limitations in the positioning system's accuracy. While seemingly insignificant, these shifts can lead to dimensional inconsistencies and shape distortions in high-precision vacuum-formed products. Therefore, we need to propose a new punching and cutting device for vacuum forming. Utility Model Content

[0004] The purpose of this utility model is to provide a blister punching and cutting device. By setting a limiting mechanism, several sets of limiting mechanisms can be used to limit the blister workpiece, which can prevent the blister workpiece from shifting during punching and cutting to a certain extent, thereby solving the problems mentioned in the background art.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution:

[0022] A vacuum forming punching and cutting device includes a base plate 1, four sets of support columns 2 are symmetrically fixedly installed on the top surface of the base plate 1, a top plate 3 is fixedly installed on the top of the four sets of support columns 2, a cylinder 4 is fixedly installed on the top of the top plate 3, a lifting plate 5 is fixedly installed through the bottom of the piston end of the cylinder 4 and the bottom of the lifting plate 5 is equipped with a punching and cutting mechanism for punching and cutting vacuum forming workpieces.

[0023] A fixing seat 9 is fixedly installed on the surface of the base plate 1. A placement plate 10 for placing the thermoformed workpiece is fixedly installed on the top surface of the fixing seat 9. Two sets of punched slots 11 are opened on the placement plate 10. A cutting groove 12 is opened on the outside of the two sets of punched slots 11. Several sets of limiting mechanisms for limiting the thermoformed workpiece are installed on the outside of the fixing seat 9 on the placement plate 10.

[0024] The limiting mechanism includes a sleeve 13, which is fixedly installed on the surface of the fixed base 9. A lifting rod 14 is slidably installed on the top of the sleeve 13. The bottom of the lifting rod 14 extends into the interior of the sleeve 13 and is fixedly connected to a sliding plate 15. A spring 16 is fixedly installed on the bottom of the sliding plate 15. The bottom of the spring 16 is fixedly connected to the inner bottom of the sleeve 13, so that the side of the thermoformed workpiece can be limited by the lifting rod 14 in several sets of limiting mechanisms.

[0025] One side of the sleeve 13 is attached to the side wall of the placement plate 10, and the top height of the sleeve 13 is lower than the surface height of the placement plate 10. This makes it easier for the mounting plate 6 in the punching and cutting mechanism to first contact and press the lifting rod 14 when it descends, so that the lifting rod 14 retracts into the sleeve 13, avoiding obstruction to the punch 7 and the cutting blade 8, and allowing the mounting plate 6 to adhere to the surface of the placement plate 10.

[0026] The punching and cutting mechanism includes a mounting plate 6, which is detachably mounted at the bottom center of the lifting plate 5. The bottom of the mounting plate 6 is fixedly mounted with punches 7 corresponding to the two sets of punching slots 11. The mounting plate 6 is fixedly mounted with cutting blades 8 corresponding to the cutting grooves 12 on the outside of the two sets of punches 7, so that the punches 7 and cutting blades 8 can be lowered and placed on the mounting plate 10 to punch and cut the shape of the thermoformed workpiece.

[0027] The mounting plate 6 is fixedly installed at the bottom of the lifting plate 5 by hex bolts. The bottom of the two sets of punches 7 is lower than the bottom of the cutting blade 8. When the mounting plate 6 descends, the two sets of punches 7 first punch holes in the vacuum forming workpiece. As the mounting plate 6 descends and adheres to the surface of the placement plate 10, the cutting blade 8 cuts the shape of the vacuum forming workpiece.

[0028] The fixing seat 9 is located below the placement plate 10 and has a cleaning groove 17. The fixing seat 9 is located at the top of the cleaning groove 17 and has a through groove connecting the two sets of punching grooves 11. When the two sets of punches 7 work together with the punching grooves 11 to punch the thermoformed workpiece, the round waste generated falls into the cleaning groove 17 through the through groove, making it easy to clean the round waste through the cleaning groove 17.

[0029] The two ends of the lifting plate 5 are slidably sleeved on the outer wall of the four sets of support columns 2. The outer wall of the support columns 2 is slidably connected to the lifting plate 5, so that the lifting plate 5 can be guided and limited when it descends by the cooperation of the four sets of support columns 2.

[0030] Working principle: When using this utility model, the vacuum-formed workpiece is placed on the placement plate 10, so that the three sides of the vacuum-formed workpiece are respectively in contact with the side walls of the lifting rods 14 in the several sets of limiting mechanisms. The lifting rods 14 in the several sets of limiting mechanisms limit the sides of the vacuum-formed workpiece. The cylinder 4 drives the bottom punching and cutting mechanism of the lifting plate 5 to descend. The four sets of support columns 2 cooperate to guide and limit the descent of the lifting plate 5. The punch 7 and the cutting blade 8 in the punching and cutting mechanism descend and cooperate with the punching groove 11 and the cutting groove 12 on the placement plate 10 to punch and cut the vacuum-formed workpiece. This can ensure the stability of the vacuum-formed workpiece to a certain extent during the punching and cutting process, effectively prevent the workpiece from deviating, and thus improve the processing accuracy of the vacuum-formed workpiece.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
