Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing equipment for die-castings, and particularly relates to a three-column trimming press. Background Art

[0002] The die-casting trimming press belongs to a common mechanism in mechanical processing, and is widely used for various purposes such as deburring of aluminum and magnesium alloy die-castings, trimming of plastic products, and pressing of powder products. The die-casting trimming press has four columns and two columns, and the combined machine is divided into specifications ranging from 1T to 160T according to the nominal pressure. Because the four columns have good stability, most die-casting trimming presses adopt a four-column structure. For trimming presses with a nominal pressure less than 5T, two columns are often used to improve the trimming efficiency and reduce the equipment investment cost.

[0003] However, with the popularization of intelligent production, multi-joint robots are often used for picking and placing materials in die-casting trimming presses. Since trimming presses with a nominal pressure greater than 5T mostly adopt a four-column structure, the multi-joint robot needs a larger walking path to avoid the columns to complete the picking and placing operations, which not only increases the picking and placing time and prolongs the production cycle, but also increases the floor space accordingly, and is not conducive to automated production and processing. Summary of the Invention

[0004] In order to overcome the above defects, the utility model provides a three-column trimming press to increase the picking and placing space, shorten the walking path of the multi-joint robot, thereby saving the production cycle and improving the production and processing efficiency.

[0026] The following is a detailed description of a preferred embodiment of the present utility model with reference to the accompanying drawings.

[0027] Refer to Figures 1 to 3 , a three-column trimming machine provided by the present utility model includes a base 1, a workbench 2 for installing a trimming lower die is provided on the base 1, columns 3 are fixedly connected to the positions of three corners of the workbench 2 respectively, a top plate 4 is connected above the three columns 3, and the workbench 2, the top plate 4 and the three columns 3 are rigidly connected to form a frame; a pressing plate 5 for installing a trimming upper die is arranged between the workbench 2 and the top plate 4, and the pressing plate 5 is slidably connected to the three columns 3; a driving system 6 is arranged on the top plate 4, and the driving system 6 includes a hydraulic cylinder 61, an oil tank 62, an oil pump 63, a servo motor 64 and an electric control box 65; one end of the oil pump 63 is connected to the hydraulic cylinder 61, and the other end is connected to the oil tank 62, and the servo motor 64 is electrically connected to the electric control box 65 for driving the oil pump 63 to extract the hydraulic oil in the hydraulic cylinder 61.

[0028] Specifically, the hydraulic cylinder 61 includes a cylinder body and a piston rod. The cylinder body is vertically arranged on the top plate 4, a through hole is opened on the top plate 4, the piston rod of the hydraulic cylinder 61 passes through the through hole and is connected to the pressing plate 5, and the piston rod moves up and down to drive the pressing plate 5 to approach or move away from the workbench 2. And under the guiding and limiting effects of the three columns 3, the pressing plate 5 moves up and down in the vertical direction. That is, the servo motor 64 rotates to drive the oil pump 63 to generate a certain pressure and a certain flow rate of hydraulic power, so that the oil pump 63 extracts the hydraulic oil and pumps the hydraulic oil into the cylinder body, and then the hydraulic oil pushes the piston rod to move. The piston rod moves to drive the pressing plate 5 to drive the trimming upper die thereon to approach the trimming lower die on the workbench 2 to cut the flash of the material. It can be understood that to ensure the overall rigidity and stability of the frame, according to the mechanical design requirements, the diameter of the column is thickened compared with the conventional column to enhance the structural strength. In addition, the three columns 3 are arranged in a triangular shape, which increases the stability of the support and expands the pick-and-place space of the multi-joint robot, so as to reduce the walking path of the multi-joint robot, thereby saving the production beat and improving the production and processing efficiency.

[0029] Further, referring to Figure 4 , the pressing plate 5 includes a main body portion 51 for installing the trimming upper die, and a reinforcing portion provided on the upper side of the main body portion 51. The reinforcing portion includes three limiting columns 52, and the three limiting columns 52 are connected to the main body portion 51 and are arranged corresponding to the three columns 3;

[0030] A through hole 521 adapted to the column 3 is formed in the limiting column 52.

[0031] The pressing plate 5 is slidably connected to the column 3 through an oil storage guide sleeve 7 provided in the through hole 521.

[0032] Further, the reinforcing portion further includes a frame structure 53 surrounding the upper side of the main body portion 51, and a connecting column 54 provided in the middle of the main body portion 51. A plurality of reinforcing rib plates 55 are connected between the frame structure 53 and the connecting column 54 to enhance the structural strength.

[0033] An installation cavity 541 adapted to the piston rod of the hydraulic cylinder 61 is formed in the connecting column 54, which ensures the effective connection between the piston rod and the pressing plate, and at the same time increases the contact surface to ensure the stability of driving.

[0034] Through the design of the pressing plate 5 with a specific structure of the plate material, while ensuring the overall rigidity of the pressing plate 5, the weight of the pressing plate is reduced to reduce the pressure on the column; in addition, by providing an oil storage guide sleeve 7 between the pressing plate 5 and the column 3, the acting force between the pressing plate 5 and the column 3 is reduced, and the service life of the column 3 is improved.

[0035] Further, the upper end of the column 3 is fixedly connected to the top plate 4 through a column nut 8. The lower end of the column 3 is supported on the workbench 2 and the end portion protrudes from the lower side of the workbench 2 and is fixed by a nut, so that while the column 3 is rigidly connected to the workbench 2 and the top plate 4, it is convenient for the disassembly and replacement of the column 3. The reason for this design is that in actual production and use, it is found that one of the columns 3 on the side opposite to the vacant corner of the workbench is worn after a long time of use, so it needs to be replaced regularly.

[0036] Further, by providing a mounting plate 41 for mounting the drive system 6 on the top plate 4, the drive system 6 is made modular, and a plurality of angle irons 42 for supporting the mounting plate 41 are provided on the side peripheral wall of the top plate 4 to stably support the mounting plate 41. At the same time, the pressure generated by the drive system on the top plate is also dispersed, and the modular setting is convenient for the replacement operation of the column.

[0037] In summary, a three-column trimming machine provided by the present utility model has columns arranged in a triangular shape between the workbench and the top plate. While increasing the stability of the support, it expands the material loading and unloading space to reduce the walking path of the multi-joint robot, thereby saving the production beat and improving the production and processing efficiency. The pressing plate is designed with a specific structure of the plate material, which not only ensures the overall rigidity of the pressing plate but also reduces the weight of the pressing plate to reduce the pressure on the columns and extend the service life of the columns.
