Abstract
Description
Technical Field
[0001] This utility model relates to the field of channel steel processing technology, and in particular to a modular C-shaped channel steel stamping die. Background Technology
[0002] In traditional mold design, one mold design is suitable for a specific type of part, resulting in limited applicability and functionality, and a long manufacturing cycle. The forming of standard belt conveyor body idler brackets, side supports, center supports, idler supports, and hanging plates all rely on a single drawing with corresponding angles and dimensions and a set of tooling. This leads to a large variety of tooling types, low tooling efficiency, inconvenient workshop tooling management, and high maintenance costs. This is especially true for the processing of I-shaped channel steel, where one upper mold corresponds to one lower mold, making management, maintenance, and replacement extremely inconvenient. Summary of the Invention
[0003] Therefore, it is necessary to provide a modular I-shaped channel steel stamping die that is easy to manage, maintain and replace.
[0004] A modular C-shaped channel steel stamping die includes an upper die base, a stamping head, two symmetrically arranged lower dies, a lower die base, and a positioning block. The lower end of the upper die base is detachably connected to the stamping head. The lower dies are located directly below the stamping head and are detachably connected to the lower die base. One side of the positioning block is connected to the lower die, and the other side of the positioning block is connected to the lower die base. The lower die includes two anti-pressure modules and several adjustment modules. The adjustment modules are sandwiched between the two anti-pressure modules. The inner anti-pressure modules and the upper end of the lower die base are provided with threaded holes. Correspondingly, the positioning block is provided with an elongated hole. The positioning block is fixed to the lower die and the lower die base by bolts.
[0005] Preferably, the lower end of the upper die base is provided with a boss, and correspondingly, the upper end of the punch head is provided with a groove. The upper die base and the punch head are engaged. Threaded holes are also provided at corresponding positions of the upper die base and the punch head. The upper die base and the punch head are fixedly connected by countersunk bolts.
[0006] Preferably, the lower die base is provided with a positioning groove, and correspondingly, the base of the external stamping machine tool is provided with a positioning bolt, the upper end of which is provided with an external thread, so as to fix the lower die base and the base of the stamping machine tool by means of a nut.
[0007] Preferably, the lower mold base is provided with a buffer groove, which is located between the two lower molds.
[0008] Preferably, the width of the adjustment module is 0.5 to 1 cm.
[0009] Beneficial Effects: In use, the modular C-shaped channel steel stamping die of this utility model determines the number of adjustment modules based on the channel width of the C-shaped channel steel. The wider the channel, the fewer adjustment modules are needed, thus increasing the distance between the pressure-resistant modules on the inner sides of the two lower dies to accommodate the channel width. After determining the number of adjustment modules, the pressure-resistant modules on the inner side of the lower die are placed tightly against the adjustment modules, then positioning blocks are placed on top, and bolts are inserted into the threaded holes of the lower base and the pressure-resistant modules. Because the positioning blocks have elongated holes, their fixation is not affected during adjustment. Simultaneously, the positioning blocks serve a positioning function, with the edges of the steel plate close to the positioning blocks, ensuring that the height of both sides of the stamped C-shaped channel steel is the same.

[0012] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0013] Please refer to Figure 1 A modular C-shaped channel steel stamping die includes an upper die base, a stamping head, two symmetrically arranged lower dies, a lower die base, and a positioning block. The lower end of the upper die base is detachably connected to the stamping head. The lower die is located directly below the stamping head and is detachably connected to the lower die base. One side of the positioning block is connected to the lower die, and the other side of the positioning block is connected to the lower die base. The lower die includes two anti-pressure modules and several adjustment modules. The adjustment modules are sandwiched between the two anti-pressure modules. The inner anti-pressure modules and the upper end of the lower die base are provided with threaded holes. Correspondingly, the positioning block is provided with an elongated hole. The positioning block is fixed to the lower die and the lower die base by bolts.
[0014] The upper die holder of this invention is used to connect to the hydraulic head of a stamping machine. The stamping machine uses the enormous punching force of the hydraulic head to stamp steel plates, forming C-shaped channel steel. The hydraulic head of the stamping machine generally consists of a hydraulic rod and a square connecting head, with the connecting head located at the end of the hydraulic rod. This invention requires first fixing the upper connecting seat to the connecting head. Then, the stamping head is connected to the upper die holder. In a preferred embodiment, the lower end of the upper die holder has a boss, and correspondingly, the upper end of the stamping head has a groove. The upper die holder and the stamping head engage. Threaded holes are also provided at corresponding positions on the upper die holder and the stamping head. The upper die holder and the stamping head are fixedly connected by countersunk bolts.
[0015] When installing the stamping head, after aligning the stamping head with the upper die base, use a countersunk screw to enter through the threaded hole at the bottom of the stamping head and tighten it. After tightening, the countersunk screw should be flush with or slightly lower than the stamping surface of the stamping head to avoid contact between the countersunk screw and the steel plate to be processed.
[0016] The lower die of this invention matches the stamping head to press the steel plate into a predetermined C-shaped groove. One lower die is provided on each side of the stamping head. The gap between the two lower dies is used to shape the C-shaped groove. The width of the C-shaped groove to be processed is adjusted by an adjustment module. When the C-shaped groove is wider, the number of adjustment modules is reduced, increasing the gap between the two lower dies.
[0017] The positioning block of this invention has two functions. First, it fixes the lower mold and lower mold base, preventing the lower mold from moving and ensuring that the adjustment module and the anti-pressure module remain in close contact. Second, it positions the steel plate, preventing it from being misaligned and causing asymmetry in the machined I-shaped channel steel.
[0018] In a preferred embodiment, the lower die base is provided with a positioning groove, and correspondingly, the base of the external stamping machine tool is provided with a positioning bolt. The upper end of the positioning bolt is provided with an external thread so as to fix the lower die base and the base of the stamping machine tool by means of a nut.
[0019] In a preferred embodiment, the lower die holder is provided with a buffer groove located between the two lower dies. When the steel plate is pressed onto the lower die holder, a large impact force is generated. At the same time, the steel plate also generates a large elastic force to resist deformation. By providing a buffer groove, this elastic force can be used to resist the impact force, thereby reducing the impact of the impact force on the lower die holder.
[0020] The function of the adjustment module is to adjust the width of the C-groove. However, if the adjustment block is too thin, it is prone to deformation during long-term extrusion, causing the C-groove to widen and the processed C-groove steel to be substandard. If the adjustment block is too thick, the number of C-grooves that can be stamped is relatively small. In a preferred embodiment, the width of the adjustment module is 0.5 to 1 cm.
[0021] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
