Embodiment 1

[0028] Such as figure 1 As shown, this embodiment includes: fuselage 3, upper beam 1, connecting rod 2, forming slider 4, clamping slider 5, spring 9, unloading screw 10, workbench 7, sucked plate 8, base 6 Wait. The fuselage 3 , the upper beam 1 and the base 6 are fixed together to form a frame, and the fuselage 3 is connected to the base 6 and the upper beam 1 . The driving system is fixed on the upper beam 1 and connected with the connecting rod 2, which can be a mechanical system or a hydraulic system or other power systems, such as hydraulic cylinders, hydraulic cylinders and the like. The connecting rod 2 drives the forming slider 4 to move along the guide rail. The mold clamping slider 5 is hoisted on the guide rail below the forming slider 4 by the unloading screw 10. There is a circular through hole in the middle of the mold clamping slider 5, and the circular through hole It is stepped. The magnetism changing device is arranged inside the clamping slider 5, which ...

Embodiment 2

[0031] Such as Figure 3-4 As shown, the magnetic changing device inside the mold clamping slider described in this embodiment is a stacked electromagnetic pole unit layer and a magnetic conduction layer; the electromagnetic pole unit layer is formed by a plurality of electromagnetic pole units arranged side by side at equal intervals horizontally ; The electromagnetic pole unit includes an iron core 16, and a coil 17 wound on the iron core 16; the magnetic permeable layer is a plurality of magnetic permeable plates 18 that are respectively sealed to each electromagnetic pole unit, and around each permeable plate Inlaid very thin magnetic spacer block 19.

[0032] Such as Figure 4 As shown, the magnetic isolation block 19 is embedded in the magnetic conductive plate; a closed loop is formed to generate magnetic attraction.

[0033] In actual use, the working mode of the press machine is similar to that of Embodiment 1, but the magnetization mode of the magnetic pole unit is...

Abstract

The invention discloses a novel double-acting press machine, and belongs to the field of double-acting press machines. According to the novel double-acting press machine, a mold closing sliding blockis hoisted below a formed sliding block in a unpowered mode, a series of variable magnetic devices are arranged inside the mold closing sliding block, a variable magnetic unit can be an electromagnetic magnetic pole unit or an electric control permanent magnet magnetic pole unit; and mold closing force is generated by attracting a sucked plate when the variable magnetic unit in the mold closing sliding block is electrified. According to the machine, the mold closing sliding block does not need to be driven by a complicated mechanical transmission structure or a hydraulic loop, and the internalstructure of the double-acting press machine is greatly simplified; the application of the mold closing force of the mold closing sliding block is large in an unit area, uniform in distribution, andsafety and reliability are achieved; during the whole working process, the magnetizing and demagnetization time is very short, and the change of the working state can be quickly responded; the double-acting press machine is similar to an existing double-acting press machine in function, and is completely capable of adapting to the work of the existing double-acting press machine.

Description

technical field [0001] The invention relates to a novel double-acting press, in particular to a double-acting press which adopts electric control permanent magnet technology or electromagnetic technology to provide mold clamping force. Background technique [0002] Double-action presses generally have two slides and are usually used in forming processes that require two or more actions, such as deep drawing or extrusion. When working, one slider is in the mold clamping or locking state first, and the other slider completes the forming process of the workpiece. After forming, the forming slider returns, and the clamping or locking slider is unloaded. In general, the driving power of the two sliders is provided by the motor through the transmission mechanism or by hydraulic pressure. This type of press needs two drives, so the structure is complicated and the manufacturing cost is high. Contents of the invention [0003] In order to solve the above-mentioned technical pro...
