Problems solved by technology

In the process of mold transformation, it is inevitable that there will be contradictions between the new structure and the existing mold state, resulting in the situation that the transformation cannot be performed or the transformation is difficult.
At this time, it is necessary to redesign the mold to meet the needs of new products, and redesigning, processing and debugging the mold is time-consuming and laborious, and is not suitable for the current production mode of small batches and multiple varieties.

Embodiment 1

[0039] Such as figure 1 , figure 2 , image 3 and Figure 4As shown, the punching die of the floating die of the automobile roof includes a floating die assembly 7, a floating die drive assembly 6, a punching and stripping assembly 8, a roof positioning assembly 10 and a mold base 9, wherein the floating Die driving assembly 6 is connected with mold base 9, and mold base 9 is installed on top cover positioning assembly 10.

[0040] Floating die assembly 7 comprises die 31, die fixed block 33, guide column 19, limiter 32, waste material guide plate 34, carriage 18, linear guide rail 20 and carriage limit block 24, wherein die 31 installs On the die fixing block 33, a guide column 19, a stopper 32 and a waste guide plate 34 are also installed on the die fixing block 33, the die fixing block 33 is connected with the carriage 18, and the linear guide rail 20 is installed on the mold base 9 , the carriage 18 is installed on the linear guide rail 20 , and the carriage 18 moves ...

Embodiment 2

[0049] refer to figure 1 , figure 2 , image 3 and Figure 5 Embodiments of the present invention will be described. The working process of the punching die of the floating die of the automobile roof is the same as that of the first embodiment, except that the punching drive assembly 25, the die drive module 15 and the clamping cylinder 39 are controlled independently by three manual valves, while The three solenoid valves are in turn connected to the power source. The manual control valve 1 controls the punching drive assembly 25 , the manual control valve 2 controls the die drive module 15 , and the manual control valve 3 controls the clamping cylinder 39 .

Embodiment 3

[0051] refer to figure 1 , figure 2 , image 3 and Figure 6 Embodiments of the present invention will be described. The working process of the floating die punching die of the automobile roof is the same as that of the first embodiment, the difference is that the punching drive assembly 25, the die drive module 15 and the clamping cylinder 39 are controlled by two solenoid valves, and the two The solenoid valve is in turn connected to the power source. The solenoid valve 1 controls the punching drive assembly 25 , and the solenoid valve 2 controls the die drive module 15 and the clamping cylinder 39 . This control method is suitable for the case where the mold is linked with the automatic punching line.

Abstract

The invention relates to a car roof floating female die punching die. The car roof floating female die punching die comprises a floating female die assembly, a floating female die driving assembly, a male die punching and material retreating assembly, a roof positioning assembly and a die base. The floating female die assembly is pushed by the floating female die driving assembly to the design position, the male die punching and material retreating assembly and the floating female die assembly complete punching and waste material retreating motion jointly, and waste materials fall into a waste material box on the roof positioning assembly through the floating female die assembly to be collected. The roof positioning assembly completes supporting, positioning and clamping motion of a punched roof. By means of the car roof floating female die punching die, the die transforming and debugging period is shortened, the new product production and preparing time is saved, the die transforming risks are reduced, the simple die is adopted for punching, and the production efficiency, the machining accuracy and the product coincidence are all better than those of a drilling hole tire repairing hole; and the floating female die structure can adapt to parts with complex appearances, a sensing device is conveniently installed above the die, a punching power part is controlled through elements such as a solenoid valve, and linkage with an automatic production line is facilitated.

Description

technical field [0001] The invention belongs to the technical field of process equipment, and in particular relates to a stamping die for a thin plate, in particular to a punching die for a floating die of an automobile top cover. Background technique [0002] Stamping die is a special process equipment for processing materials into parts or semi-finished products during cold stamping processing. It is called cold stamping die, commonly known as cold stamping die. Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to a material at room temperature to cause separation or plastic deformation to obtain the required parts. The materials for manufacturing stamping dies include steel, hard alloy, zinc-based alloy, low melting point alloy, aluminum bronze, polymer materials, etc. [0003] Stamping dies are indispensable industrial equipment in stamping production and are technology-intensive products. The quality, production efficienc...
