Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to an adjustable hydraulic press support base. Background Art

[0002] The working principle of hydraulic press is to use Pascal's law and transmit through liquid pressure. Specifically, the oil pump delivers hydraulic oil to the integrated cartridge valve block, and distributes the hydraulic oil to the upper or lower chamber of the cylinder through various one-way valves and overflow valves. Under the action of high-pressure oil, the cylinder moves. It is often used in the field of mechanical processing, such as stamping.

[0003] In the process of implementing the solution, the inventors found that the following problems in the prior art have not been well solved: the hydraulic press is installed on a support base, and the support base does not mean just a simple base. Some hydraulic presses press down from top to bottom, while the support base is a frame type. The top of the base contains another base, also called a top base. The four corners between the two bases are fixed by support columns, and the hydraulic press is installed on the base of the top base. The pressed parts are placed above the base between the top of the base and the telescopic end of the hydraulic press. When placing the parts, the telescopic end of the hydraulic press needs to retract, and when it retracts to the shortest point, the distance between its end and the base is fixed, and the height of some pressed parts exceeds this distance, which makes it impossible to use the fixed-size hydraulic press to perform the pressing process on the pressed parts. Utility Model Content

[0004] The main purpose of the utility model is to provide an adjustable hydraulic press support base, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The cam is secured to the bottom of the base and is easily broken away from the base by the engagement of the camshaft and the spring, and the cam is secured to the bottom of the base with a spring that is fixed to the base on an outer surface of the base.

[0007] Preferably, the flanges are respectively seated on the tops of the extension seats, and the bolts 1 pass through one end of the flanges and are respectively inserted into the interiors of the screw grooves 2 that match the positions and are threadedly connected thereto.

[0008] Preferably, the tops of the bottom columns are respectively inserted into the through cavities, and the outer diameters of the bottom columns are respectively matched with the inner diameters of the through cavities.

[0009] Preferably, a rod cavity is excavated at the bottom of each of the top rods, the position of the rod cavity is respectively perpendicular to the position of the bottom column below, and the inner diameter size of the rod cavity matches the inner diameter size of the bottom column.

[0010] Preferably, the outer walls of the push rods are all dug with reinforcement grooves, the interiors of the reinforcement grooves are all embedded with reinforcement ribs, the reinforcement ribs are respectively welded to the push rods, and the welding method is full welding.

[0011] Preferably, several of the bolts 2 at the bottom pass through one end of the connecting seat and are respectively inserted into the interior of screw groove 1 and threadedly connected thereto, and several of the bolts 2 at the top pass through one end of the connecting seat and are respectively inserted into the interior of screw groove 3 and threadedly connected thereto.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The hydraulic press is installed at the bottom of the upper base. When the distance between the telescopic end of the upper base and the top of the lower base is not enough to place the workpiece, after the hydraulic cylinder works, its telescopic end rises, which will push the extension seat to rise together. After the extension seat rises, the bottom column will descend in the through-hole, and the distance between the telescopic end of the hydraulic press and the top of the lower base will increase, so that the workpiece can be placed on the lower base. This adjustable base can process workpieces at a higher height through the hydraulic press, increasing the processing range. BRIEF DESCRIPTION OF THE DRAWINGS
