Background

An arcuate pin is a pin-like piece on an automobile that is shaped like an arcuate shape for connecting, securing or locating parts. Arcuate pins are used to connect various components of an automobile, such as leaf springs and brackets in suspension systems, to ensure a reliable connection between the components to transmit forces and movements. The parts are accurately arranged at specific positions on the automobile, and the relative position accuracy among the parts, such as the installation and positioning of certain parts on the engine cylinder body, is ensured. The body of the arcuate pin is typically made of a high strength metal, such as alloy steel or the like. In the production of arcuate pins, it is often necessary to press-form a metal raw material using a die. However, because the hardness of the metal raw material is high, the die used in the stamping process and the workpiece are frequently rubbed and extruded, and the abrasion phenomenon is very easy to occur. Once the key parts of the die are worn, the molding precision of the die is reduced, so that the produced arch pin is unstable in size deviation and quality, and the assembly and the overall performance of the automobile are affected. While conventional arcuate pin production mold designs lack consideration for convenient replacement of the easily worn portions. When the problem occurs at the easily worn part of the die, the whole die is often required to be disassembled and maintained, and even the whole die is directly replaced. This not only results in a complex maintenance process, which consumes a lot of manpower, material resources and time costs.

The top of the lower die holder 2 also adopts a T-shaped groove structure, and the T-shaped bulge at the bottom of the lower molding piece 21 is matched with the T-shaped bulge to be positioned and then is fixed by a fastening bolt. At the same time, the opposite sides of the upper molding piece 11 and the lower molding piece 21 are respectively provided with a profiling groove 3 matched with the shape of the arched pin, and when the die is closed, the two profiling grooves 3 are spliced to form a complete arched pin molding cavity.

As production continues, the upper molding 11 and the lower molding 21 are frequently contacted with the raw material, rubbed, and worn. When wear reaches a certain level, affecting the molding quality of the arcuate pin, component replacement may be performed. When the upper molding piece 11 is replaced, only the fastening bolt is required to be unscrewed, the worn upper molding piece 11 is pulled out of the T-shaped groove, then the T-shaped bulge of the new upper molding piece 11 is embedded into the T-shaped groove, and the fastening bolt is screwed, so that the replacement is completed. The replacement of the lower molding member 21 is performed similarly, and the replacement of the lower molding member 21 can be completed quickly by a simple operation.

When the die is used for producing the arch pin, the lower die holder 2 is fixed on a workbench of a press machine, and the upper die holder 1 is driven to move downwards by a driving device of the press machine. When the upper die holder 1 gradually approaches the lower die holder 2, the upper molding piece 11 and the lower molding piece 21 are matched with each other, and the two profiling grooves 3 are gradually closed. The pretreated raw material is placed in the imitation groove 3, and the press continuously applies pressure to enable the raw material to be plastically deformed in the cavity, so that the required arch pin is formed. After the forming process is finished, the press drives the upper die holder 1 to move upwards, the die is opened, and the formed arch pin is taken out. The upper molding part 11 and the lower molding part 21 are designed in a detachable manner, when the parts are worn, the whole mold is not required to be detached and maintained, and only the worn parts are required to be replaced, so that the maintenance time of the mold is greatly shortened, the production dead time caused by the maintenance of the mold can be reduced, and the production efficiency is remarkably improved. The setting of detachable shaping spare for the operating personnel is convenient for in time change wearing and tearing part, has avoided the shaping precision decline because of the part wearing and tearing lead to, has guaranteed product quality's stability.

The lower die holder 2 is provided with a pin hole 22, and the pin hole 22 penetrates through the lower molding piece 21 and corresponds to the positioning pin 12.

In the production process, as the upper die holder 1 approaches the lower die holder 2, the upper molding piece 11 and the lower molding piece 21 approach each other, the positioning pin 12 of the upper die holder 1 is inserted into the pin hole 22 of the lower die holder 2, the upper molding piece 21 and the lower molding piece 21 are guided to be accurately butted, and the profiling grooves 3 of the upper molding piece and the lower molding piece are closed to form a molding cavity. The cooperation of the locating pin 12 and the pin hole 22 effectively limits the displacement of the upper and lower forming parts 21 in the opening and closing process of the mould, prevents dislocation caused by mould vibration or impact and ensures the forming quality of the arch pin.

Further, a clamping block 23 is arranged at the top of the lower die holder 2, the length direction of the clamping block 23 is along the length direction of the lower die holder 2, a clamping groove 211 is arranged at the bottom of the lower molding piece 21, the clamping block 23 is matched with the clamping groove 211, a first fastening bolt is further arranged on the lower molding piece 21, and the fastening bolt is in threaded connection with the lower die holder 2.

When the lower molding piece 21 is mounted on the lower die holder 2, the clamping groove 211 at the bottom of the lower molding piece 21 is aligned with the clamping block 23 of the lower die holder 2, and sliding embedding is performed along the length direction of the clamping block 23, so that the preliminary positioning of the lower molding piece 21 in the horizontal direction is realized. Then, the first fastening bolt passes through a preset threaded hole on the lower molding member 21 to be in threaded connection with the lower die holder 2, so that the lower molding member 21 is firmly fixed. The matching of the clamping block 23 and the clamping groove 211 improves the stability and accuracy of the installation of the lower forming piece 21
