DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model will be further explained in detail below in combination with specific implementation manners and with reference to the drawings. It should be understood that these descriptions are only exemplary, and are not intended to limit the scope of the utility model. In addition, in the following description, the description of the known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0027] This utility model discloses an automatic shaping device for die-cast workpieces, used for the automatic shaping of aluminum alloy die-cast workpieces where excessive deformation makes it impossible to locate the reference point. For details, see [link to details]. Figures 1 to 5 The system mainly includes a forming platform 10, a positioning component 20, a forming component 30, a detection sensor 50, and a main beam forming component 40. The positioning component 20, forming component 30, sensor, and main beam forming component 40 are all mounted on the forming platform 10. The forming platform 10 is a square platform with a bottom support. An inverted U-shaped truss 12 is provided above the forming platform 10. The positioning component 20 and main beam forming component 40 are mounted on this truss 12 and can be vertically raised and lowered relative to the truss 12. A positioning platform 11 is provided in the middle of the forming platform 10 and below the truss 12. A fixing station for fixing the die-cast part 70 to be formed is formed on this positioning platform 11 (as an alternative embodiment, the fixing station can also be directly formed on the forming platform 10). The positioning component 20 rises and falls vertically and presses against the die-cast part 70 to be formed on the fixing station during descent, facilitating subsequent forming by the forming component 30. The shaping component 30 is mounted on the shaping platform 10 and located on the side of the positioning table 11 or fixed station. Specifically, it includes a first shaping component 31 and a second shaping component 32, wherein the first shaping component 31 is responsible for shaping the die-cast part 70 in the vertical direction (i.e., as shown in the image). Figure 4 The shaping process involves the first shaping component 31 moving up and down relative to the die-cast part 70 to be shaped, striking the die-cast part 70 with up-and-down movements. The second shaping component 32 is responsible for shaping the die-cast part 70 in the front-back direction (i.e., as shown in the diagram). Figure 4The shaping of the front and back direction (the second shaping assembly 32) hits the to-be-shaped die casting 70 before and after the shaping process. In the embodiment of the present application, the to-be-shaped die casting 70 is placed in the fixed station by manual feeding, and the automatic fixing of the to-be-shaped die casting 70 is realized through the positioning assembly 20, and then the to-be-shaped die casting 70 is positioned and the up and down and front and back direction movements are realized to realize automatic shaping. The shaping efficiency is high and the product yield is also high. The detection sensor 50 is electrically connected with the first shaping assembly 31 and the second shaping assembly 32 and connected with the external PLC control system (not shown). The PLC system has a model of the die casting that can be positioned (defined as reference data). Specifically, the detection sensor 50 includes a first sensor 51 electrically connected with the first shaping assembly 31 and a second sensor 52 electrically connected with the second shaping assembly 32. The first sensor 51 and the second sensor 52 respectively detect the deformation test data of the to-be-shaped die casting 70 in the up and down direction and the front and back direction, and then transmit the deformation test data to the PLC control system. The PLC control system compares the deformation test data with the built-in reference data (which also includes the up and down direction and the front and back direction reference data) and generates deviation data. Then the deviation data is fed back to the first shaping assembly 31 and the second shaping assembly 32, and the first shaping assembly 31 and the second shaping assembly 32 perform corresponding shaping according to the deviation data. This part belongs to the existing conventional control logic, and is not the innovation point of the present application. The innovation point of the present application is the overall structure of the shaping device. The main beam shaping assembly 40 is used for shaping the main beam of the to-be-shaped die casting. It should be noted that the detection sensor 50 is also electrically connected with the main beam shaping assembly 40.

That is, the shaping platform 10 is also provided with a slide rail (not marked) and a slide driving module (not shown) for the positioning table 11 to slide.

[0029] In some preferred embodiments, the second sensor 52 can be driven to move up and down, that is, as shown in the up and down direction. Figure 4 Specifically, as shown in Figure 3 and Figure 4As shown, two opposite and spaced vertical lifting rails 523 are arranged on the truss 12, and the two lifting rails 523 can be respectively fixed on the rear side of the two vertical frames of the inverted U-shaped truss 12. A transverse fixing plate 522 is slidably arranged on the lifting rails 523, and the second sensor 52 is installed on the front side of the transverse fixing plate 522. A lifting module 521 connected with the transverse fixing plate 522 is arranged at the upper end of the truss 12 behind the shaping drive of the girder shaping assembly 40, and the lifting module 521 drives the transverse fixing plate 522 to vertically ascend and descend to adjust the height of the second sensor 52. It should be noted that the number of the second sensor 52 in the embodiment is multiple, and the number and arrangement manner are not described and limited, and a person skilled in the art can select and design according to actual needs. For example, the multiple second sensors 52 are sequentially arranged in different height directions. And during shaping, it is in the ascending position, and only when detection is needed, it can descend. The purpose is to avoid interference with the second shaping assembly 32 to affect the shaping operation or even cause damage during the shaping operation. Similarly, the number of the first sensor 51 is also multiple, which is arranged on the positioning table 11. The number and arrangement manner are not described and limited, and a person skilled in the art can select and design according to actual needs. For the first sensor 51 and the second sensor 52, the conventional optical fiber sensor or photoelectric sensor on the market can be selected.

[0030] For the positioning assembly 20, the number of the positioning assembly 20 in the embodiment of the utility model is two, and the two positioning assemblies 20 are Figure 4 arranged on the truss 12 in opposite and spaced left-right directions. Any positioning assembly 20 includes a positioning drive 21 which can vertically ascend and descend, and a positioning block 22 (exemplarily, multiple circular positioning blocks 22 which are stacked) installed on the drive end of the positioning drive 21. Exemplarily, the positioning drive 21 is a hydraulic cylinder, and a hydraulic station 60 connected with the hydraulic cylinder and providing hydraulic power for the hydraulic cylinder is further arranged on the side of the shaping platform 10.

Figure 4 The rear left and right ends are shown. Regarding the structure of the first shaping component 31 and the second shaping component 32, their structures are roughly similar, both consisting of a three-axis module plus a shaping claw. One module in the three-axis module serves as the driving component for the shaping claw. That is, the difference lies in the different driving components and the different structures of the shaping claws. Specifically, in this embodiment, the two first shaping components 31 are used for shaping in the vertical direction. Specifically, as shown...

The specific structure of the second shaping claw is not described and limited, and can be designed according to the to-be-shaped die casting 70. The structure of the two second shaping claws of the two second shaping assemblies 32 can be the same or different. It should be noted that in the embodiment, the first moving module 311 of the two first shaping assemblies 31 is responsible for driving the respective corresponding first drive assemblies along the length direction of the shaping platform 10, that is, the front-rear direction shown in the figure.
