Description

Technical Field

[0001] This utility model belongs to the field of press technology, specifically relating to a press with a multi-guide rod device. Background Technology

[0002] In modern industrial production, presses are an important type of mechanical equipment widely used in metal processing, plastic molding, wood processing and other fields. The core function of a press is to change the shape or physical properties of materials by applying pressure. In order to improve the working efficiency and stability of presses, multi-guide rod devices are widely used in press design to ensure that the guide rods can move evenly and stably during the application of pressure.

[0003] However, there are some technical problems in the existing multi-guide rod press design. For example, traditional multi-guide rod devices usually use a horizontally bent connecting rod to connect the guide rod and the drive mechanism of the press. Although this design can ensure the synchronous movement of the guide rod to a certain extent, in actual application, the connecting rod is prone to damage or even breakage because it bears a large pressure and bending moment during the pressing process. This damage not only affects the service life of the press, but may also cause production accidents and economic losses to enterprises.

[0004] To address these issues, some technicians have attempted to improve the durability of the connecting rod by increasing its material strength and altering its cross-sectional shape. However, these methods often increase the overall weight and manufacturing cost of the press, and the results are not ideal.

[0005] Therefore, there is an urgent need for a new type of multi-guide rod device to circumvent the aforementioned defects. Utility Model Content

[0006] The purpose of this invention is to provide a press with a multi-guide rod device that can effectively prevent damage or breakage of the second connecting rod during the pressing process while ensuring synchronous movement of the guide rod body. This improves the stability and service life of the press, and reduces production costs and safety risks.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] A press with a multi-guide rod device includes a press body, a working chamber is provided inside the press body, and an installation chamber is provided inside the press body and at the top of the working chamber.

[0009] Multiple hydraulic cylinders are installed on the top of the inner side of the installation chamber. The stroke rod of the hydraulic cylinder is fixed to a connecting plate vertically downward. Three guide rod bodies are slidably connected inside the press body and at the bottom of the connecting plate.

[0010] A connecting structure is installed between the guide rod body and the connecting plate, and the connecting structure is used to connect the connecting plate and the guide rod body.

[0011] The connecting structure includes a first connecting rod, which is fixed to the bottom of the connecting plate and vertically connected to one of the guide rod bodies. A second connecting rod is fixed to both sides of the top of the first connecting rod, and the bottom of the second connecting rod is inclined to the side away from the first connecting rod. A fixing structure is connected to the bottom of the second connecting rod, and one of the other two guide rod bodies is connected to the bottom of the fixing structure.

[0012] The connection structure includes a connecting block fixed to the top of the guide rod body, a top mounting block fixed to the bottom of the second connecting rod, and an abutment protection block provided at the bottom of the top mounting block, with the abutment protection block extending into the interior of the connecting block.

[0013] Multiple bolts are threadedly connected between the top mounting block and the connecting block, and tight gaskets are provided inside the top mounting block and the connecting block, both located outside the bolts.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This invention can effectively prevent the second connecting rod from being damaged or broken during the pressing process while ensuring the synchronous movement of the guide rod body, thereby improving the stability and service life of the press and reducing production costs and safety risks.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figure 1-4 As shown, a press with a multi-guide rod device includes a press body 1, a working chamber 2 is provided inside the press body 1, and an installation chamber 3 is provided inside the press body 1 and at the top of the working chamber 2.

[0025] Multiple hydraulic cylinders 4 are installed on the top of the inner side of the installation chamber 3. The stroke rod of the hydraulic cylinder 4 is fixed vertically downward to the connecting plate 5. Three guide rod bodies 7 are slidably connected inside the press body 1 and at the bottom of the connecting plate 5. When the hydraulic cylinder 4 is started, it can drive the connecting plate 5 to move down and drive the guide rod bodies 7 to move downward, so that the workpiece can be pressed through the guide rod bodies 7.

[0026] A connecting structure is installed between the guide rod body 7 and the connecting plate 5. The connecting structure is used to connect the connecting plate 5 and the guide rod body 7.

[0027] See attached document Figure 3 The connecting structure includes a first connecting rod 6, which is fixed to the bottom of the connecting plate 5, and the bottom of the first connecting rod 6 is vertically connected to one of the guide rod bodies 7.

[0028] When the connecting plate 5 moves down, it can drive the first connecting rod 6 to move down, and drive the guide rod body 7 at the middle position to move down.

[0029] A second connecting rod 9 is fixed on both sides of the top of the first connecting rod 6, and the bottom of the second connecting rod 9 is inclined towards the side away from the first connecting rod 6. Furthermore, the angle of inclination of the second connecting rod 9 is an acute angle. With this setting, when the second connecting rod 9 is subjected to force, most of the force is downward, while a small part of the force is directed towards the side away from the first connecting rod 6. This acute angle is preferably no more than 45°, thereby reducing the force directed outward when the second connecting rod 9 is subjected to force and ensuring the life of the second connecting rod 9 under stress.

[0030] When the second connecting rod 9 is tilted, it can avoid the following: Figure 5The inconvenience caused by the horizontal fold structure shown is that when the second connecting rod 9 is subjected to the force of the connecting plate 5, it can press the guide rod body 7 downward. When pressed, the force can be distributed into a downward force and a force away from the first connecting rod 6, so that the second connecting rod 9 can avoid breaking due to excessive force.

[0031] Furthermore, a fixed structure is connected to the bottom of the second connecting rod 9, and one of the other two guide rod bodies 7 is connected to the bottom of the fixed structure.

[0032] See attached document Figure 4 The connecting structure includes a connecting block 8 fixed to the top of the guide rod body 7, a top mounting block 10 fixed to the bottom of the second connecting rod 9, and a bottom abutment protection block 11 provided at the bottom of the top mounting block 10, extending into the interior of the connecting block 8. Multiple bolts 12 are threadedly connected between the top mounting block 10 and the connecting block 8. Furthermore, the bolts 12 are positioned around the edges of the connecting block 8 and the top mounting block 10. This arrangement allows the bolts 12 to provide a tight connection between the connecting block 8 and the top mounting block 10. Furthermore, the top mounting block 10 and the connecting block 8 are both provided with bolts 12 inside and outside the bolts 12. The tight pad 13 is provided. By setting the abutment protection block 11, the abutment protection block 11 can reduce the load on the bolt 12 by abutting against the connecting block 8. When the second connecting rod 9 is under force, it is an outward force. If this force is only supported by the bolt 12, it will reduce the service life of the bolt 12. By setting the abutment protection block 11, the force on the bolt 12 can be reduced. By setting the tight pad 13, the tight pad 13 can increase the tightness between the top mounting block 10 and the connecting block 8 and the bolt 12, and can buffer the force when the bolt 12 is under force.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
