Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, and in particular to an energy-saving connecting rod type pressure device. Background Technology

[0002] Pressure equipment is widely used in machining and quality inspection. Currently, most pressure equipment is unidirectional pressure equipment that uses a single vertical pressure source, such as hydraulic presses, cylinders, and electric actuators. Pressure equipment can be used to provide the vertical pressure required for machining processes such as cutting, punching, bending, and riveting, or to apply vertical pressure to the parts to be tested to complete the pressure test of the parts, or to clamp molds or parts to be processed.

[0003] Chinese utility model patent CN219881027U discloses a multi-directional pressure device, including a base and a frame fixedly mounted on the base. A pressure source is vertically mounted on the frame, with the telescopic rod of the pressure source facing the base. Vertical pressure blocks are provided on one or more sides of the pressure source on the frame. The pressure blocks are fixedly connected to the telescopic rod via pressure plates and can move vertically with the telescopic rod. A laterally sliding pressure receiving block is provided on the base opposite the pressure blocks. The upper end face of the pressure receiving block and the lower end face of the pressure block are in contact and are both inclined. The pressure receiving block can slide laterally toward the pressure source as the pressure blocks move downward. This pressure device directly applies pressure from the force source to the object being pressured, resulting in poor flexibility.

[0004] Therefore, existing technologies need to be improved and enhanced. Utility Model Content

[0009] As a further embodiment of this invention, the cylinder is fixedly connected to an electromagnetic controller.

One end of the first connecting rod is hinged to the movable pressure rod, and the other end is hinged to one end of the second connecting rod and the third connecting rod. The other end of the second connecting rod is hinged to the fixed plate, and the other end of the third connecting rod is hinged to the upper pressure table.

[0011] As a further embodiment of this utility model, the lower end of the movable pressure rod passes through the fixed plate and is fixed to a fixed rod, and the two first connecting rods are respectively hinged to the two ends of the fixed rod.

[0012] As a further embodiment of this utility model, two upper supports are provided on the lower surface of the fixing plate, and the other ends of the two second connecting rods are respectively hinged to the two upper supports that are symmetrically arranged about the center line of the fixing plate.

[0013] As a further embodiment of this utility model, two or more lower supports are provided on the lower surface of the upper pressure table, and the other ends of the two third connecting rods are respectively hinged to the two lower supports that are symmetrically arranged about the center line of the upper pressure table.

[0014] Compared with the prior art, the beneficial effects of this utility model are: Due to the aforementioned structural design, the cylinder pressure assembly drives the upper die on the upper pressure platform and the lower die on the lower load-bearing platform through the connecting rod assembly to achieve riveting and stamping operations. This application transmits pressure to the target point through the connecting rod assembly, and by shifting the position of the working point, different output pressures can be provided, offering high flexibility and good energy-saving effects.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0018] In the description of this application, "several" or "more than" means two or more, unless otherwise explicitly specified. In this application, unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," "fixed," etc., should be interpreted broadly.

Example

[0020] like Figure 1 and Figure 2As shown, this application discloses an energy-saving linkage-type pressure device, comprising a lower support platform 10, a lower die 20 mounted on the lower support platform 10, two guide columns 30 symmetrically arranged on both sides of the lower die 20, a fixing plate 40 fixed to the top of the two guide columns 30, a cylinder pressure assembly 50 mounted in the middle of the fixing plate 40, an upper pressure platform 60 disposed below the cylinder pressure assembly 50, two linkage assemblies 70 disposed between the cylinder pressure assembly 50 and the upper pressure platform 60, and an upper die 80 disposed on the upper pressure platform 60 that cooperates with the lower die 20. Through the above structural design, the cylinder pressure assembly drives the upper die on the upper pressure platform and the lower die on the lower support platform to cooperate through the linkage assemblies to achieve riveting and stamping operations. Since this application transmits pressure to the target point through the linkage assemblies, different output pressures can be provided by shifting the position of the working point, thus providing high flexibility.

[0021] Specifically, the upper pressure table 60 is provided with two sliding sleeves 61, which are slidably fitted onto the two guide posts 30. When the upper pressure table moves up and down under the action of the cylinder pressure assembly, the cooperation between the sliding sleeves and the guide posts enables the upper pressure table to move smoothly along a predetermined path.

[0022] Specifically, the cylinder pressure assembly 50 includes a movable pressure rod 51 and a cylinder 52 that drives the movable pressure rod 51. The cylinder 52 is fixedly connected to an electromagnetic controller 53, which sends electromagnetic commands to the cylinder. The cylinder drives the movable pressure rod to drive the connecting rod assembly, thereby driving the upper pressure table and the upper mold to move downward, thus achieving mold closure.

[0023] Specifically, the linkage assembly 70 includes a first linkage 71, a second linkage 72, and a third linkage 73. One end of the first linkage 71 is hinged to the movable pressure rod 51, and the other end is hinged to one end of the second linkage 72 and the third linkage 73. The other end of the second linkage 72 is hinged to the fixed plate 40, and the other end of the third linkage 73 is hinged to the upper pressure table 60. The lower end of the movable pressure rod 51 passes through the fixed plate 40 and is fixed to a fixed rod 54. The two first linkages 71 are respectively hinged to both ends of the fixed rod 54. Two plurality of upper supports 41 are provided on the lower surface of the fixed plate 40. The other ends of the two second linkages 72 are respectively hinged to the two upper supports 41 symmetrically arranged about the center line of the fixed plate 40. Two plurality of lower supports 62 are provided on the lower surface of the upper pressure table 60. The other ends of the two third linkages 73 are respectively hinged to the two lower supports 62 symmetrically arranged about the center line of the upper pressure table 60. By setting several upper supports on the fixed plate and several lower supports on the upper pressure table, the working point position can be moved through the linkage assembly, thereby providing different output pressures. It is highly flexible and energy-saving.

[0024] In summary, this utility model, through the above-described structural design, overcomes the shortcomings of the prior art and features a reasonable structure, flexibility, and strong practicality.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
