Description

Technical Field

[0001] The utility model belongs to the technical field of pressing machines, and in particular relates to an automatic pressing machine workbench. Background Art

[0002] In the foundry industry, pressurizing castings is essential to achieve a denser, more compact finished product without internal pores. However, traditional presses rely on manual loading and unloading, as well as mold changes. This is not only inefficient but also poses significant safety risks. Furthermore, the uncontrollable nature of manual operation often makes it difficult to ensure the precision and consistency of castings, compromising product quality and performance.

[0003] The traditional press workbench is typically a fixed platform, onto which the castings need to be manually moved and then manually adjusted by the operator to align them with the press's hydraulic rods. This process is not only time-consuming and labor-intensive, but can also easily lead to damage to the castings or personal injury due to improper operation. Utility Model Content

[0004] In response to the above problems, the purpose of the present utility model is to provide an automatic pressing machine workbench to solve the problem that the traditional pressing machine requires manual transportation of the casting to be pressed to the bottom of the hydraulic rod of the pressing machine and then transported and removed after processing, which is not only inefficient but also poses a safety hazard.

[0013] In order to ensure the accuracy of the hydraulic rod's pressing position;

[0014] As a further improvement of the above technical solution: when the electric push rod is retracted to the end of the stroke, the axis of the limit ring and the casting forming shell is collinear with the axis of the hydraulic rod and the pressure column.

[0015] The beneficial effect of this improvement is that after the electric push rod is retracted into place, the hydraulic rod can be extended to work and accurately press the die-casting placed in the casting shell through the pressing column.

[0016] In order to ensure the stability of the workbench plate lifting;

[0017] As a further improvement of the above technical solution: the number of the heavy-load cylinders is four, and they are respectively arranged at the four corners of the worktable.

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0032] Example 1:

[0033] like Figure 1-4 shows: an automatic pressing machine workbench, including a pressing machine 1, a hydraulic rod 2 is installed on the upper side of the pressing machine 1, a pressing column 3 is installed at the bottom end of the hydraulic rod 2, a controller 4 and a liftable workbench 5 are installed on the pressing machine 1, and the liftable workbench 5 includes an electric push rod 51, one end of the electric push rod 51 is rotatably installed on the side of the pressing machine 1 through a pin shaft, the other end of the electric push rod 51 is rotatably connected to one end of a connecting arm 1 52 through a pin shaft, the middle end of the connecting arm 1 52 is rotatably connected to a support seat 53 through a pin shaft, and the support seat 53 is installed on the pressing machine 1, and the side of the pressing machine 1 is rotatably connected to one end of a connecting arm 2 58 through a pin shaft, and the other ends of the connecting arm 2 58 and the connecting arm 1 52 are rotatably connected through a pin shaft. The two ends of the connecting rod 54 are dynamically connected, and the connecting rod 54 is connected to a side plate 55. A heavy-duty cylinder 56 is installed on the side plate 55. The piston rod of the heavy-duty cylinder 56 is connected to a workbench 57. A limit ring 6 is installed on the workbench 57. The inner side of the limit ring 6 is adapted to be placed with a casting forming shell 7. A travel switch 8 is installed on the top side of the pressing machine 1. The parallelogram connecting rod structure driven by the electric push rod 51 realizes the smooth lifting and automatic loading and unloading of the workbench 57. The combination of the auxiliary support of the heavy-duty cylinder 56 and the automated die-casting process triggered by the travel switch 8 significantly improves the production efficiency and operation safety, while ensuring the accuracy and stability of the casting during the die-casting process. The top surface of the workbench 57 is parallel to the pressing The supporting surface at the bottom of the machine 1 is installed on the pressing machine 1, and the connecting arm 2 58, the connecting arm 1 52, and the connecting rod 54 form a parallelogram connecting rod structure. Under the drive of the electric push rod 51, the work table 57 moves stably parallel to the supporting base surface of the pressing machine 1, so that the die-casting in the casting forming shell 7 can be stably lifted and lowered. When the electric push rod 51 is extended to the end of the stroke, the bottom surface of the work table 57 is flush with the bottom of the pressing machine 1. When the electric push rod 51 is extended to the maximum length, the operator can easily load and unload materials between the work table 57 and the ground. When the electric push rod 51 is retracted to the end of the stroke, the axis of the limit ring 6 and the casting forming shell 7 are collinear with the axis of the hydraulic rod 2 and the pressing column 3. After the electric push rod 51 is retracted into place, the hydraulic rod 2 can be extended to work by accurately pressing the die casting placed in the casting forming shell 7 through the pressing column 3. The number of the heavy-duty cylinders 56 is four, and they are respectively arranged at the four corners of the work table 57. The number of the heavy-duty cylinders 56 is four, and they are respectively arranged at the four corners of the work table 57. When the bottom surface of the work table 57 is flat and fits the table surface of the pressing machine 1, the contact of the travel switch 8 is squeezed by the work table 57. The controller 4 is electrically connected to the contact of the travel switch 8 and the oil circuit solenoid valve of the hydraulic rod 2. After receiving the closing signal of the travel switch 8, the controller 4 can control the hydraulic rod 2 to automatically extend for pressing. The number of the electric push rods 51 is two, and they are relatively arranged on the left and right sides of the pressing machine 1.The two electric push rods 51 can drive the side panels 55 arranged on both sides of the workbench 57 to rise and fall stably, ensuring the stability of the rise and fall of the workbench 57.

[0034] The working principle of this technical solution is as follows: the die casting to be pressed is placed inside the casting shaping shell 7, and then the casting shaping shell 7 is placed on the working table 57 inside the limiting ring 6, and then the electric push rod 51 is controlled to shrink. When the electric push rod 51 shrinks, it drives the connecting arm 1 52 to rotate with the pin shaft on the support seat 53 as the support, and when the connecting arm 1 52 rotates, it cooperates with the connecting arm 2 58 to rotate the connecting rod 54, and the connecting rod 54 drives the working table 57 to move upward, thereby transporting the die casting to the top of the table of the pressing machine 1. After the electric push rod 51 shrinks into place, the heavy-duty cylinder 56 automatically extends, driving the working table 57 down. The work table 57 is moved so that it is pressed against the table of the pressing machine 1, ensuring the position stability of the work table 57 during the die-casting process. When the work table 57 is pressed against the pressing machine 1, the contacts of the travel switch 8 are squeezed by the work table 57, and the circuit of the travel switch 8 is closed. After receiving the signal from the travel switch 8, the controller 4 controls the valve path state of the solenoid valve of the hydraulic rod 2, thereby extending the hydraulic rod 2 and driving the pressing column 3 to move, thereby pressing the die-casting in the installed casting forming shell 7. After the pressing is completed, the hydraulic rod 2, the heavy-load cylinder 56, and the electric push rod 51 are reset in sequence, and the operator can remove the casting safely and labor-savingly.
