Description
Technical Field
The invention belongs to the technical field of magnetic material production equipment, and particularly relates to a wet hydraulic blank taking system for realizing protective demoulding.
Background
The magnetic material mainly refers to a substance which is composed of transition elements such as iron, cobalt, nickel and alloys thereof and can directly or indirectly generate magnetism. The magnetic material is an important basic functional material in the electronic industry, and is widely applied to the industrial fields of computers, electronic devices, communication, automobiles, aerospace and the like and daily necessities such as household appliances, children toys and the like.
For the manufacture of magnetic products, when a wet-type forming hydraulic press is used, a manual pressing product generally adopts a protective demolding mode (when an upper cylinder and a lower cylinder are opened, the lower cylinder returns first, and the upper cylinder returns again, in this mode, when filter paper is separated from the product, the product is not in a cavity, and when the upper cylinder returns, the product can be brought up by the upper cylinder due to the viscosity of the filter paper). The problems of using protective demoulding products are few, and the qualification rate is high. The blank taking machine can only be used for general demoulding, and cannot be used for protective demoulding, and because the protective demoulding filter paper can lift the product upwards, the blank taking machine can only be used for general demoulding, so that the product percent of pass can be reduced.
Through search, the Chinese patent application No. 201410764292.6, application date 2014.12.11 "a wet-pressing magnetic tile demoulding method", which comprises the following steps: (1) placing the raw material above the punch, and pressing the upper die downwards to form the raw material; (2) keeping the upper die still, moving the middle die on the side edge of the punch under the control of a time relay or a PLC (programmable logic controller), and controlling the demolding position to release the internal stress at the joint of the chord long surface and the outer arc surface of the product in advance; (3) the middle mold is kept still, the upper mold returns to the original position, and demolding is complete. The internal stress at the joint of the arc long surface and the outer arc surface of the product is released in advance by a secondary demoulding method, and the product cannot return along with the upper die and stays on the punch; but the middle molds on the two sides need to control the demolding position and then perform one-time demolding, so that the using time of two-time demolding is long, and the production efficiency is delayed.
Also, for example, in chinese patent application No. 200610024658.1, application date 2006.03.14, "a release agent for wet molding of magnetic material and a method for preparing the same", kerosene is used as a medium, higher fatty acid, polyethylene wax or organic silicon is used as a release agent for an effective component of release, and after the kerosene medium is volatilized, a release substance can be uniformly distributed on the surface of a mold, thereby remarkably improving the release effect of a magnetic material blank. However, when a blank taking machine is used for taking blanks in a wet-type forming hydraulic machine, the products are demoulded by protection, and the problem that when the blanks are taken by the machine, the products are demoulded by protection at the same time due to the fact that the filter paper is brought upwards by an upper cylinder cannot be solved.
Both of the above two patent documents provide solutions to the problem of demolding of magnetic material by wet forming, but neither of them can use a blank-taking machine for protecting demolding while using a magnetic material wet forming machine on the basis of not changing the original pressing structure of the machine, and achieve good use effect.

And fourthly, carrying out protective demoulding treatment, namely when the upper cylinder and the lower cylinder are opened, withdrawing the lower cylinder, and demoulding the upper cylinder in a return stroke mode. Fifthly, after the protection and demolding are finished, the time relay starts to work, the blank taking machine starts to take blanks, the secondary magnetizing auxiliary relay works, and secondary magnetizing starts. And finally, finishing secondary magnetization, and taking out the non-magnetic blank by a blank taking machine.
Example 2
The structure of the wet hydraulic blank taking system for realizing the protective stripping is the same as that of the embodiment 1, and the difference is that the working process is further described. Three numerical value input elements are arranged on the touch screen and respectively delay the blank taking machine, the secondary magnetizing time and the secondary magnetizing current. When debugging the product, properly turning up the demagnetization current a little, properly turning up the demagnetization time a little, making the magnetism of demagnetization be greater than the magnetism of magnetization before, after the product has the magnetism of demagnetization, use the protection drawing of patterns, when opening the mould, the lower cylinder returns, the upper cylinder returns, the product can be because there is magnetism to be tightly absorbed on the mould drift 143, so the product can not be brought upwards by filter paper 180, for the convenience of piling up and subsequent convenient sintering, the product can not take magnetism, so need to give the magnetism of going back more before and disappear, so need to magnetize the product twice and disappear the magnetism that goes back more before. Magnetizing and demagnetizing are to change the direction of the coil direct current and change the direction of the magnetic field according to the right-hand spiral rule. When the upper cylinder and the lower cylinder are back to the upper limit and the lower limit, the PLC gives a signal capable of taking a blank to the blank taking machine through a program, the blank taking machine starts to take the blank, a time relay is added at the moment, the time of the blank taking machine entering the time delay is recorded, the time delay is input from a touch screen, and the time is the time from the time when the blank taking machine enters the blank to the time when a sucker sucks the product, and is determined when the product is debugged. When the blank taking machine enters the delay time, the secondary magnetizing auxiliary relay obtains a signal, secondary magnetizing is started, the secondary magnetizing time relay starts timing, the time is input from the touch screen, a signal is simultaneously given to magnetizing current, the coil starts magnetizing, the current is input from the touch screen, when the secondary magnetizing time is up, the secondary magnetizing signal is interrupted, the magnetizing is finished, and the automatic program is returned. The blank taking machine is delayed, the secondary magnetizing time and the secondary magnetizing current are all debugged and input when a product is debugged, and the fact that the product is taken out and does not have magnetism is guaranteed.
In the pressing process, the magnetizing of the magnetic tiles ensures that the magnetic powder particles of the pressed and formed magnetic tiles are uniformly oriented, the consistency of magnetism is stable, and the quality of products is improved. The excessive demagnetization treatment is carried out on the magnetic shoe to remove the magnetism of the magnetic shoe during pressing and ensure that the magnetic shoe can be protected and demoulded. After the demolding is finished, the magnetic shoe is magnetized for the second time, the magnetism of the magnetic shoe is completely eliminated, and the magnetic interference of the magnetic shoe during stacking and transportation is avoided.
The above examples illustrate the invention and its embodiments, without limitation. It should be noted that those skilled in the art should also understand that they can design the similar structural modes and embodiments without departing from the spirit of the invention, and they should also fall into the protection scope of the invention.
