Description

Technical Field

[0001] The utility model belongs to the technical field of stamping equipment, and particularly relates to a material changing mechanism for a double-mode machine set. Background Art

[0002] In the aspect of the forging technology of the speaker T-iron, blanking needs to be carried out first when the speaker T-iron is forged and formed. When the blank parts go through the stamping process, the traditional technological process is that the blank parts are clamped by manual operation and then placed on a punching press, and then the punching press operates to carry out the stamping and forming of the speaker T-iron. The required size is finally achieved through two stampings, but the material needs to be changed between two sets of molds during the two stampings; manual operation will cause delays in the mold manufacturing time and reduce the forging efficiency; moreover, the position of each manual placement is inaccurate, resulting in different shapes and sizes during the forging of the speaker T-iron; due to the high temperature and heat of the blank parts, it is easy to make operation mistakes during loading and unloading, causing the speaker T-iron to fall or even scald the body.

An extending cylinder is arranged on the sliding frame on the side of the rotating plate close to the driving motor, and the extending end of the extending cylinder passes through the central circular hole in the mounting hole set and extends to the front side of the rotating plate.

[0010] The technical solutions of the present utility model will be further specifically described below through embodiments in conjunction with the drawings.

[0011] Embodiment: A material changing mechanism for a double-mode machine set, as Figure 1 shown, includes a driving motor 1, a rotating plate 2 is connected to the driving shaft of the driving motor 1, two sets of mounting hole groups are symmetrically arranged on the rotating plate 2, each set of mounting hole groups includes a central circular hole 3 and two rectangular holes 4 symmetrically arranged on both sides, a sliding frame 5 is inserted on the rotating plate 2 corresponding to each set of mounting hole groups, the sliding frame 5 includes two slide rails 6, which pass through the rectangular hole 4 from one side of the driving motor 1 to the other side of the rotating plate 2 and are fixedly connected to the rotating plate 2, an extending cylinder 7 is arranged on the sliding frame 5 on the side of the rotating plate 2 close to the driving motor 1, the extending end of the extending cylinder 7 passes through the central circular hole 3 in the mounting hole group and extends to the front side of the rotating plate 2, a clamping cylinder 8 is arranged in each of the two sliding frames 5, the left and right ends of the clamping cylinder 8 are slidably connected to the two slide rails 6 of the sliding frame 5, and a clamping arm 9 is arranged on each of the two sliding blocks of the clamping cylinder 8.

[0012] At the front ends of the two clamping arms 9 of each clamping cylinder 8, mutually cooperating clamping grooves 10 are arranged; a lifting cylinder 11 for driving the driving motor 1 to rise is arranged above the driving motor 1.

[0013] Principle of the present utility model: During the manufacturing process of the T-iron, the bar stock needs to be first stamped to the required diameter. After the first stamping of the bar stock is completed, it is transferred to the second forming die, and the blank is stamped into shape by the forming die. Both dies are installed on the punching press and are stamped synchronously. The material changing mechanism is arranged at the rear side of the punching press, and the extending end of the extending cylinder 7 is installed in the direction of manual operation. During the stamping process, the operator puts the blank into the first die, and the punching press stamps. After completion, the extending cylinder 7 quickly extends, and a group of clamping cylinders 8 drive two clamping arms 9 to clamp the blank in the first group of dies; another group clamps the formed blank in the forming die, and then quickly retracts. The rotation of the driving motor 1 drives the rotating plate 2 to rotate. After the rotation is completed, the extending cylinder 7 extends. The extension and retraction of the extending cylinder 7 are for making way to avoid collision with the die. During the rotation process, the clamping cylinder 8 clamping the formed blank is loosened to unload the formed blank, and another group of clamping cylinders 8 puts the blank into the forming die. After completion, it rotates in the reverse direction to reset. At the same time, the operator puts the unstamped blank into the first die and repeats the process in turn. In order for the blank to be smoothly ejected from the die, a lifting cylinder 11 is provided to drive the driving motor 1 to float, so that there is an upward movement after the clamping arm 9 clamps the blank.

[0014] Finally, it should be pointed out that the above embodiments are only relatively representative examples of the present utility model. Obviously, the present utility model is not limited to the above embodiments and can have many variations. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model shall be considered as belonging to the protection scope of the present utility model.
