Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, specifically to a heating stamping forming device for plastic parts. Background Technology

[0002] Stamping is a forming method that uses a press and dies to apply external force to sheet metal, strip, tube, etc., causing plastic deformation or separation to obtain workpieces of the desired shape and size. Compared with other processing methods, stamping has many advantages in both technology and economy. Stamping can produce parts with thin walls, light weight, and high surface quality that are difficult or impossible to manufacture using other methods. Stamping of plastic sheets is mainly for thermoplastics. Thermoplastics have good stamping properties after heating. For stamping of round cap-shaped workpieces, the current process generally involves first heating the sheet metal with heating equipment, then placing it in a die for stamping, and finally removing it for trimming after cooling. The entire process requires workers to transfer intermediate products, resulting in low production efficiency. Utility Model Content

[0007] Compared with existing technologies, the advantages of this invention are as follows: This device uses a heating coil to heat the sheet metal to be stamped on a mold. After heating, stamping is performed directly. After the mold is closed, motor A drives the mold to rotate, and the stamped workpiece rotates synchronously. The cutting head moves laterally to approach the workpiece for trimming to remove excess material. During the processing, there is no need for manual transfer of intermediate products, which helps to improve processing efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0012] Please see Figure 1-2 This utility model provides a technical solution: a heating and stamping forming device for plastic parts, including a base 1 and a stamping die. The stamping die includes an upper die 5 and a lower die 6 that are opposite each other. A fixed frame 3 is installed on the upper side of the base 1. A vertical pressing cylinder 4 is fixedly installed on the lower side of the fixed frame 3. A rotatable upper die 5 is installed at the lower end of the piston rod of the pressing cylinder 4. A rotatable lower die 6 is installed on the base 1.

A heating coil 13 is mounted on the front end of the mounting arm. The heating coil 13 is sleeved on the stamping die. The heating coil 13 can be moved up and down to adjust its height by being pushed by the push cylinder 7. After being energized, the heating coil 13 moves down closer to the sheet metal to heat it and soften the sheet metal material. A coolant nozzle 8 is mounted on the machine base 1. A water pump is installed in the water tank 2. The output end of the water pump is connected to the coolant nozzle 8 through a pipe. The coolant nozzle 8 is located on one side of the stamping die and cools and shapes the stamped workpiece by spraying coolant. A motor a9 is mounted on the machine base 1.
