Description

Technical Field

[0001] This utility model relates to the field of truck manufacturing technology, specifically to a stamping die for truck manufacturing parts. Background Technology

[0002] Truck manufacturing is a complex industrial process involving multiple stages from design and material selection to production and assembly. As a heavy-duty transportation vehicle primarily used for transporting goods, trucks must be designed and manufactured with consideration for factors such as load-bearing capacity, durability, and safety. During truck manufacturing, some internal parts require stamping. The design of a stamping die for a truck manufacturing part typically involves the forming requirements of specific components, such as body panels, chassis, and brackets. With advancements in manufacturing technology, the design and function of stamping dies are constantly evolving. The application of advanced materials, automation technology, and intelligent manufacturing will further improve die performance and production efficiency; however, existing stamping dies for truck manufacturing parts still have certain shortcomings.

[0003] For example, the patent application CN201922065094.1, entitled "A Stamping Die for Parts in Railway Freight Car Manufacturing," includes a stamping machine worktable. A die fixing groove is installed at the upper end of the stamping machine worktable. The die fixing groove is welded to the stamping machine worktable. A lower stamping die is installed inside the die fixing groove. The lower stamping die is connected to the die fixing groove via a slot. An upper stamping die is installed above the lower stamping die. A power column is installed at the upper end of the upper stamping die. The power column is connected to the upper stamping die via screws. The upper stamping die is connected to the lower end of the upper stamping die, and the first stamping die column is welded to the upper stamping die. As can be seen from the above, although this kind of stamping die for railway freight car manufacturing parts can be used well, it cannot adjust the height of the equipment according to the different heights of the raw materials when stamping them, and it cannot reciprocate the stamping of the raw materials, thus failing to guarantee the quality of the stamped raw materials. During the stamping process, it cannot buffer the lower die body, and when the stamping force is too large, it is easy to damage the parts, which often troubles users. Utility Model Content

Drive shaft 14 is fixedly installed on left wall of drive motor 13. Bevel gear set 15 is fixedly installed on left wall of drive shaft 14, and the upper top surface of left side of bevel gear set 15 is fixedly installed through the lower end of lead screw 2.

[0023] A sprocket 16 is fixedly installed through the lower end of the lead screw 2. The lead screw 2 and the sprocket 16 are symmetrically arranged about the center of the base 1, and the two sprockets 16 are meshed with a chain 17. The upper top surface of the base 1 is slidably connected to the lower mold body 18, and the lower bottom surface of the lower mold body 18 is inlaid with a first slide rod 19 at the front right side.

[0024] A connecting block 20 is fixedly installed on the front end of the right wall of the lower mold body 18. A second slide rod 21 is slidably connected through the upper top surface of the connecting block 20, and the lower bottom surface of the second slide rod 21 is embedded and fixedly installed on the upper top surface of the base 1. A spring 22 is sleeved on the lower part of the second slide rod 21, and the lower end of the spring 22 is fixedly installed on the upper top surface of the base 1.

[0026] Working principle: When using a stamping die for truck manufacturing parts, the user first places the raw material inside the lower die body 18. The drive motor 13 is started, driving the drive shaft 14 to rotate. The rotation of the drive shaft 14 drives the bevel gear set 15 to rotate, which in turn drives the lead screw 2 and sprocket 16 to rotate. Through the meshing of the two sprockets 16 with the chain 17, the two lead screws 2 are simultaneously driven to rotate. The meshing of the lead screw 2 with the top plate 3 adjusts the height of the upper die body 12. Then, the transmission motor 4 is started, driving the transmission shaft 5 and the first pulley 6 to rotate. The rotation of the upper mold body 12 is achieved through the transmission connection between the first pulley 6 and the second pulley 9, which drives the rotating rod 8 to rotate. The rotation of the rotating rod 8 drives the cam 10 to rotate, and through the hinge between the cam 10 and the fixed block 11, the upper mold body 12 moves up and down reciprocally to press the raw material. During the pressing process, to prevent the pressing force from being too large, the lower mold body 18 is buffered by the spring 22, the second slide rod 21 and the first slide rod 19, thereby completing a series of tasks.
