Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a stamping die for a C-pillar reinforcement of an automobile. Background Technology

[0002] Cars are a very common means of transportation in modern daily travel. Since the C-pillar of a car mainly plays a supporting and protective role, the strength requirements of the C-pillar are relatively high. In the process of processing the C-pillar, a reinforcing stamping die is generally used to assist in completing the stamping and forming of the C-pillar.

[0003] In the stamping process of automotive C-pillar reinforcement parts, existing molds generally suffer from insufficient material positioning accuracy. Traditional molds require manual adjustment of the material position before stamping, which is time-consuming and prone to introducing deviations. At the same time, the material placed correctly during stamping is prone to deviations before stamping, affecting the finished product. To address this, we propose a stamping mold for automotive C-pillar reinforcement parts. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a stamping die for automotive C-pillar reinforcement, which can quickly position the material and avoid material deviation during the stamping process, thus effectively solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamping die for a C-pillar reinforcement of an automobile, comprising a base plate and a support assembly;

[0006] Base plate: A lower die base is fixed on the upper side, and a stamping assembly is installed on the upper side of the base plate. The stamping assembly corresponds to the lower die base, and an air extraction assembly is installed on the left side of the lower die base.

[0007] Support assembly: includes connecting grooves, guide tubes, guide rods, support frame, and springs. The lower mold base has a guide groove on its edge, and a support frame is positioned above the guide groove. Four corresponding connecting grooves are located at the four corners of the guide groove. An opening is formed at the lower end of each connecting groove, and a guide tube is fixed inside the opening. Guide rods are slidably connected inside the guide tube. The upper ends of the four guide rods are fixed to the lower side of the support frame. Springs are fitted onto the circumference of each guide rod, with the upper end of the spring fixed to the lower side of the support frame and the lower end fixed to the lower end of the connecting groove. An adsorption assembly is installed on the side of the support frame, and an air extraction assembly is connected to the adsorption assembly. This support assembly supports the material used to manufacture the automotive C-pillar reinforcement.

[0008] Furthermore, the adsorption assembly includes a suction cup, an air inlet pipe, a connecting pipe, an air guide pipe, and a solenoid valve. Four corresponding grooves are provided on the upper side of the support frame. A suction cup is fixed inside each groove, and an air inlet pipe is fixed inside the air inlet of each suction cup. The four air inlets are connected by a connecting pipe. An air guide pipe is fixed inside an air injection hole on the circumferential surface of the connecting pipe, and a solenoid valve is installed on the circumferential surface of the air guide pipe. The input end of the solenoid valve is electrically connected to the output end of an external control switch assembly. The adsorption assembly is used to adsorb the material of the car's C-pillar reinforcement.

[0009] Furthermore, the air extraction assembly includes an air extraction pump and an air injection hose. The air extraction pump is installed on the left side of the lower mold base. An air injection hose is fixed inside the air outlet of the air extraction pump. The upper end of the air injection hose is fixed to the lower end of the circumferential surface of the air guide pipe. The air injection hose is connected to the air guide pipe. The input end of the air extraction pump is electrically connected to the output end of an external control switch group. By setting the air extraction assembly, the gas inside the four suction cups is extracted.

[0010] Furthermore, the stamping assembly includes a connecting frame, a hydraulic rod, a connecting plate, and an upper die head. The connecting frame is fixed to the upper side of the base plate, and a hydraulic rod is installed on the upper side inside the connecting frame. A connecting plate is fixed to the telescopic arm of the hydraulic rod, and an upper die head is fixed to the lower side of the connecting plate. The upper die head and the lower die base correspond to each other. The input end of the hydraulic rod is electrically connected to the output end of an external control switch group. The stamping assembly is used to stamp the material of the C-pillar reinforcement of the automobile.

[0011] Furthermore, four corresponding extrusion heads are fixed on the lower side of the connecting plate, and an extrusion disc is fixed at the lower end of the extrusion head. The extrusion disc corresponds to the connecting groove. By setting the extrusion heads and extrusion discs, the support frame is extruded so that it can enter the guide groove opened on the side of the lower die base during stamping.

[0012] Furthermore, two corresponding limiting blocks are fixed at the left and right ends of the lower side of the connecting plate, and two corresponding limiting grooves are opened on the left and right sides of the guide groove opened on the upper side of the lower mold base. The limiting blocks and limiting grooves correspond to each other. By setting the limiting blocks and limiting grooves, the stability of the connecting plate when it moves downward can be effectively guaranteed.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This stamping die for automotive C-pillar reinforcement has the following advantages:

[0014] 1. The combined effect of a spring-reset support frame and negative pressure adsorption enables automatic material positioning and release during the stamping process. After the support frame accurately sinks into the guide groove during stamping, it automatically returns to its initial position via spring action upon completion of stamping. This, along with a vacuum adsorption system controlled by a solenoid valve, forms a complete automated cycle of positioning, stamping, and demolding, significantly improving production cycle efficiency.

[0015] 2. A multi-dimensional positioning system is constructed through the mechanical positioning of the limiting block and the limiting groove combined with the dual fixing mechanism of negative pressure adsorption. During the stamping process, the vertical guiding movement of the support frame and the horizontal limiting of the connecting plate form spatial positioning compensation. Combined with the planar fixing effect of vacuum adsorption, the positional deviation in the three-axis direction is effectively eliminated, ensuring the dimensional accuracy of complex curved surface parts.

[0027] The working principle of the stamping die for a C-pillar reinforcement of an automobile provided by this utility model is as follows: After the C-pillar reinforcement material to be stamped is laid flat on the upper surface of the support frame 34, the air pump 51 of the air extraction component 5 is started, and air is continuously extracted into the air guide pipe 44 of the adsorption component 4 through the air injection hose 52. At this time, the solenoid valve 45 is in the closed state, and the gas is extracted from the suction cup 41 through the connecting pipe 43 and the four air inlet pipes 42 in sequence. Under the action of negative pressure, the material is firmly adsorbed onto the surface of the support frame 34. When the hydraulic rod 62 of the stamping component 6 drives the connecting plate 63 to move down, the four extrusion heads 7 and extrusion discs 8 fixed below the connecting plate 63 first contact the four corners of the support frame 34. Under the action of pressure, the support frame 34 moves axially along the guide rod 33 to compress the spring 35, so that the guide rod 33 slides smoothly in the guide pipe 32, and drives the support frame 34, which adsorbs and fixes the material, to sink into the guide groove on the side of the lower die base 2. At this time, the limiting blocks 9 on both sides of the connecting plate 63 are simultaneously inserted into the limiting grooves 10 of the lower die base 2, ensuring that the upper die head 64 and the lower die base 2 are precisely aligned to complete the stamping process. After stamping, the hydraulic rod 62 retracts, the spring 35 releases its elastic force to push the support frame 34 back to its initial height, and at the same time controls the solenoid valve 45 to open and release the vacuum adsorption, allowing the operator to safely remove the formed workpiece. The entire process achieves zero offset fixation of the material during the stamping process through the dual action of mechanical positioning and negative pressure adsorption.

[0028] It is worth noting that the external control switch group disclosed in the above embodiments is equipped with buttons that correspond one-to-one with the solenoid valve 45, the air pump 51 and the hydraulic rod 62. The solenoid valve 45, the air pump 51 and the hydraulic rod 62 can be freely configured according to the actual application scenario.
