Description

Technical Field

[0001] The utility model relates to the technical field of vehicle parts manufacturing, in particular to a stamping die structure and a forming device shared by left and right parts of multiple vehicle models. Background Art

[0002] For similar models, there are usually similar parts, which have slight differences in features such as external dimensions, number and position of holes, etc. Take single-row trucks (hereinafter referred to as P trucks) and double-row trucks (hereinafter referred to as PS trucks) as examples. P trucks have only one row of seats in the cab, which can only carry two passengers, the driver and the co-driver, leaving the space behind for the cargo box. In addition to the row of seats in the cab, PS trucks also have another row of seats for passengers, which can generally carry a total of 5 passengers. This type of truck is about 700mm shorter than the cargo box of P trucks.

[0003] The left and right side beam parts are the frame structural parts of the car floor assembly of P and PS cars, which play the role of connecting the car floor, car floor reinforcement plate, and wheel cover guard parts to form a closed frame at the bottom of the entire car. Figure 1 As shown in the figure, the left and right side beam parts of the PS car are not completely symmetrical parts. The right side beam part 2 of the PS car has an additional fuel filler avoidance gap 3 compared to the left side beam part 1 of the PS car. This type of part is connected to the edge of the car floor on one side and to the car floor reinforcement plate and wheel cover guard on the other side. This type of part is a simple and slender part (length * width: P car 3094mm * 62mm * 80mm / PS car

[0004] 2394mm*62mm*80mm), such as Figure 2 As shown, the main differences between the left side beam part 5 of the P car and the left side beam part 4 of the PS car are the position of the hinge plate mounting boss, the difference in the number of part holes, the different hole positions, etc. The above-mentioned P car and PS car are divided into conventional cars and container trucks respectively. Conventional cars are trucks with sideboards installed, and container trucks are trucks with sideboards removed and the cargo compartment completely enclosed. The main difference between the left and right side beam parts of conventional cars and container trucks is that the left side beam part 6 of the P car / PS container truck has 10 more holes for mounting the cargo compartment on the basis of the left side beam part 7 of the P car / PS conventional car, as shown in FIG. Figure 3 shown.

[0005] At present, the left and right side beam parts mentioned above are stamped by stamping dies. Three sets of dies are used for the left and right side beam parts of P car and PS car respectively, namely, the P car die group and the PS car die group. Each set of dies is designed and manufactured according to the unique characteristics of each car model. All dies are switched across the board every time the parts production is switched, which is costly and inefficient. Utility Model Content

The molding upper mold guide leg 910 and the molding lower mold guide groove 914 constitute the above-mentioned second guide limit assembly.

[0069] A molding mold storage column 915 is also provided on the molding lower mold base 902. The molding mold storage column 915 is used to rigidly limit the clamping distance between the upper and lower molds of the molding mold 9 when the molding mold 9 is not in use, thereby preventing the internal pressure source of the mold (such as the above-mentioned second nitrogen spring 916, etc.) from being in a pressurized state all the time, thereby increasing the service life of the pressure source.

[0070] A second support rack 913 is provided on one side of the lower forming die base 902 to facilitate the processed parts to leave the forming die 9 and reduce the work intensity of the workers.

During the downward movement, the forming punch assembly 903 of the upper die seat 901 cooperates with the forming concave die assembly 904 of the lower die seat 902 to obtain the desired shape of the molded part.

[0073] During the working movement, the second nitrogen spring 916 provides a pressure source for the forming press core 905, and when the upper and lower mold seats are not closed in place, the second nitrogen spring 916 is always in a state of force compression until the mold is closed in place, and the second nitrogen spring 916 is also compressed to the final position. When the work is completed and the molding mold 9 is opened, the second nitrogen spring 916 provides power for the molding press core 905 to reset. The press core pressure plate is installed on the molding lower mold seat 902, which plays a role in limiting the movement stroke of the molding press core 905 and preventing it from falling. The press core guide plate 906 allows the molding press core 905 to reciprocate at a fixed position in the mold cavity without deviation, ensuring the movement stability of the molding press core 905.

[0074] Because the switching of holes for conventional cars and container cars of P and PS cars has been designed in the blanking die, and the left and right parts are designed to be stamped and produced simultaneously in the front and rear cavities in the subsequent die, the subsequent die does not involve the switching between conventional cars and container cars and the left and right parts, but only involves the switching between P and PS cars.
