Descriptions of well-known functions and constructions are omitted for clarity and conciseness.
Fig. 1 shows an embodiment of the present invention, specifically an electromagnetic pulse diffusion welding apparatus, and fig. 1 shows the main structure of this embodiment. As can be seen from fig. 1, the electromagnetic pulse diffusion welding apparatus includes a first base 107, and a second base 105 disposed above the first base 107 and opposite to the first base 107. The work 106 is set on the first base 107. The upper pressure head 103 is connected above the second base 105; the lower ram 108 is attached below the first base 107. The upper press head 103 and the lower press head 108 push the second base 105 and the first base 107, respectively, to apply pressure to the work piece 106. Of course, when the upper ram 103 is raised upward, the pressure applied to the workpiece 106 may be removed and a space is made available for the workpiece 106 to be removed and placed. The first base 107, the second base 105, and the work 106 are disposed in a vacuum chamber surrounded by the vacuum chamber housing 104.
It can also be seen from fig. 1 that the power supply 101 is connected to a frequency conversion device 102, the connection lines of which frequency conversion device 102 are in turn connected to a first pedestal 107 through the vacuum chamber housing 104. As can be seen in fig. 3, a pipe groove 301 is provided on the first base 107. The duct 301 is an elongated duct provided on the first base 107. With reference to fig. 2, it can be seen that an electromagnetic induction copper tube 202 is disposed within the elongated slot. The electromagnetic induction copper pipe 202 is connected with the electrode connector 201. The connection line of the frequency conversion device 102 is electrically connected with the electrode connector 201 to supply power to the electromagnetic induction copper tube 202. The electromagnetic induction copper pipe 202 is a hollow copper pipe, and a cooling medium (e.g., water or oil) can flow through the hollow portion.
The specific structure of the first base 107 can be observed in conjunction with fig. 3 and 4. The first base 107 is formed by stacking a plurality of silicon steel sheets with the same shape. The silicon steel sheet group is formed by stacking a plurality of silicon steel sheets, each silicon steel sheet is provided with through holes with the same position, and the silicon steel sheet group is also provided with the through holes. The fixing rod 402 penetrates through the through hole on the silicon steel sheet group. The aluminum fixing plate 302 is sleeved at two ends of the fixing rod 402 (i.e. two outer sides of the silicon steel sheet set). The securing rod 402 is externally threaded adjacent both ends thereof. The internal thread of the nut 303 is matched with the external thread, the nut 303 is sleeved on the fixing rod 402, and the silicon steel sheet group and the aluminum fixing plate 302 are fastened to form the first base 107. The silicon steel sheet belongs to a magnetic conductive material.
Fig. 5 shows a specific structure of the second base 105 in the embodiment shown in fig. 1. The structure of the second base 105 is substantially the same as that of the first base 107 (refer to fig. 4), except that no grooves for accommodating the copper tubes for electromagnetic induction are provided on the second base 105 (in the present embodiment, no copper tubes for electromagnetic induction need be provided on the second base 105). Other structural features of the second base 105 in fig. 5 are the same as those of the first base 107 shown in fig. 4, and are not repeated herein.
The technical solution of the present invention will be further explained with reference to the working process of the embodiment shown in fig. 1.
First, the work 106 is placed on a first base 107.
Secondly, the actuator is started, and the upper pressing head 103 and the lower pressing head 108 respectively push the second base 105 and the first base 107 to move towards the workpiece 106, so as to clamp the workpiece 106 and apply a preset pressure. Of course, in other embodiments, only the upper ram 103 and its corresponding actuator may be provided, relying only on the movement of the upper ram to perform the clamping and pressing operations. In other embodiments, the first base 107 and the second base 105 may be arranged in other orientations, such as the left and right directions of the workpiece 106, and it is only necessary to keep the first base 107 and the second base 105 arranged opposite to each other and move the workpiece 106 to be pressed.
It is thus clear that adopt the technical scheme of the utility model, can process great size work piece, need not be equipped with the electronic circuit of bigger size, the electronic circuit who has solved the production electromagnetic field occupies the problem in great space. Simultaneously, because the size between first base and the second base can be adjusted, consequently, can separate both earlier, produce great space, conveniently place the work piece, the difficult first base of touching of work piece and second base. After the machined workpiece is placed to a proper position, the first base and the second base are close to the machined workpiece, and the problem that an electronic circuit is easily damaged when the machined workpiece is placed is solved.
And thirdly, vacuumizing the vacuum chamber, and stopping vacuumizing after the vacuum chamber reaches a preset vacuum degree.
Fourth, the power supply 101 and the frequency conversion device 102 are started. At this time, the electromagnetic induction copper pipe 202 as the electromagnetic generation cable generates a pulse magnetic field between the first susceptor 107 and the second susceptor 105. The first base 107 and the second base 105 are made of silicon steel sheets, and the silicon steel sheets are made of magnetic conductive materials, so that a magnetic field can be formed between the first base 107 and the second base 105. Meanwhile, the aluminum fixing plate 302 is made of aluminum, which is not a magnetic conductive material and does not interfere with the magnetic field formed between the first base 107 and the second base 105. Meanwhile, the aluminum has low hardness and can adapt to the uneven surface of the silicon steel sheet, so that the contact area between the aluminum fixing plate 302 and the silicon steel sheet is large, and the effect of fastening the silicon steel sheet group is good. In addition, the electromagnetic induction copper pipe 202 is flowed with a cooling medium, thereby preventing the first base 107 from overheating and preventing the aluminum fixing plate 302 from changing its properties after overheating.
In other embodiments, in addition to the electromagnetic induction copper tube 202 being disposed in the tube slot 301 of the first base 107 in the present embodiment, the electromagnetic induction copper tube 202 may also be disposed in an inner hole (similar to the hole of the first base 107 through which the fixing rod 402 passes) formed in the first base 107.
In other embodiments, a second electromagnetic generating cable may also be provided on the second base 105 at the same time. The second electromagnetic generation cable is matched with the electromagnetic induction copper pipe 202 on the first base 107 to generate a pulse magnetic field, so that the efficiency is improved.
Fifth, after the set time and temperature are reached, the power supply 101 is stopped, and the process of machining the workpiece 106 is completed.
The utility model discloses an electromagnetic pulse hot working equipment can also carry out other hot working process such as thermoforming, and the range of application is extensive.
It should be noted that the above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, and the present invention can also be modified in materials and structures, or replaced by technical equivalents. Therefore, all structural equivalents which may be made by applying the present invention to the specification and drawings, or by applying them directly or indirectly to other related technical fields, are intended to be encompassed by the present invention.
