Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Fig. 2 is a schematic structural diagram of a hydraulic head.
The hydraulic control system comprises an installation frame 1, a hydraulic cylinder 2, an operation table 3, a hydraulic rod 4, a hydraulic head 5, a stress block 6, a magnet 7, an installation seat 8 and a matching groove 9.
Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.
As shown in fig. 1, the utility model provides a metal material cold upsetting test tool, which comprises an installation frame 1, a hydraulic machine and an operation table 3; the hydraulic machine comprises a hydraulic cylinder 2 and a hydraulic rod 4, a detachable hydraulic head 5 is arranged at the end part of the hydraulic rod 4, and a detachable stress block 6 is arranged on the operating platform 3; the hydraulic cylinder 2 is fixed on the mounting frame 1, and the hydraulic rod 4 is arranged along the vertical direction; the force-bearing block 6 is fixed below the hydraulic head 5. When the metal material is subjected to plasticity detection, the columnar material needs to be compressed to two thirds of the length to see whether cracks exist on the surface, and high requirements on the contact surface are provided while high pressure needs to be provided. Although the material of the hydraulic head 5 and the operation table 3 is good, the metal to be detected has high strength and generates a dent in long-term operation. Therefore, the hydraulic head 5 which is directly contacted with the metal material to be detected and the corresponding part of the operating platform 3 are arranged to be detachable, and the maintenance cost can be reduced by only replacing the hydraulic head 5 when the hydraulic head 5 is damaged.
In one embodiment, a magnet 7 is arranged in the hydraulic rod 4, a matching groove 9 for inserting the hydraulic rod 4 is arranged on the hydraulic head 5, the bottom of the matching groove 9 is in contact fit with the end of the hydraulic rod 4, and the side wall of the matching groove 9 is in clearance fit with the hydraulic rod 4. The common detachable connection mode is that connecting pieces such as bolts are connected or clamped. The lower terminal surface of hydraulic pressure head 5 must keep leveling, and the connecting piece needs to follow the radial setting of hydraulic stem 4, and this one side can influence the intensity of pneumatic cylinder 2, and on the other hand, for example bolt or pin junction, when hydraulic pressure head 5 atress, connecting piece itself also can receive very big radial force, warp easily, and inconvenient dismantlement after warping, if the damage screw, then maintain inconveniently more. If clamping and the like are adopted, the connector and the hydraulic rod 4 are difficult to attach, and the closer the attachment is, the more difficult the clamping is. During pressing, the hydraulic rod 4 or the hydraulic head 5 is easily damaged due to head deviation. Utilize magnet 7 to adsorb, as long as the contact surface precision is suitable, can reach fine laminating degree to do not have the connecting piece atress, magnet 7 can set up the cavity in hydraulic stem 4 and place. The side wall of the matching groove 9 is in clearance fit with the hydraulic rod 4, so that even if the metal material to be detected is slightly inclined, the radial force between the hydraulic rod 4 and the side wall of the matching groove 9 can be prevented, and the radial deformation of the hydraulic rod 4 can be prevented.
Preferably, the stress block 6 is cylindrical, and the diameter of the stress block 6 is the same as that of the hydraulic rod 4 and is coaxially arranged with the hydraulic rod 4. When the work piece was placed on atress piece 6, the position of pressfitting is in the coverage of hydraulic stem 4 all the time, and 5 marginal pressfittings of hydraulic ram can not appear and lead to the sideslip phenomenon, even hydraulic ram 5 does not have strict coaxial with hydraulic stem 4, does not influence the normal clear of pressfitting yet.
Preferably, the height of the upper surface of the force-bearing block 6 is obviously higher or lower than that of the upper surface of the operation table 3. This makes it possible to clearly distinguish whether the material to be tested is completely placed on the force-bearing block 6, preventing human error.
Preferably, the operating platform 3 is provided with an installation seat 8, and the operating platform 3 is provided with a groove for placing the installation seat 8; and a groove for placing the stress block 6 is formed in the mounting seat 8. The upper surface of the stress block 6 should be kept flat, and the installation of the stress block is convenient by arranging the installation seat 8; meanwhile, the mounting seat 8 can also play a role in increasing the stressed area, so that the material performance requirement of the operating platform 3 is reduced, and meanwhile, the operating platform 3 is prevented from being damaged.
Preferably, the lower end of the hydraulic rod 4 is a plane. The atress between atress piece 6 and the hydraulic stem 4 is more corresponding like this, and hydraulic head 5 plays direct contact's effect, has still played the effect that local atress rear portion disperses to hydraulic stem 4 lower extreme.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
