Abstract
The invention relates to the field of casting shaping technologies, in particular to a heating shaping method. One-time appropriate shaping can be achieved, and efficiency is greatly improved. The method comprises the following steps that firstly, a shaping tool is installed on a base; secondly, a workpiece needing to be shaped is heated to 800-850 DEG C, and the heated workpiece is placed on the shaping tool; thirdly, a hydraulic machine is started to press the upper surface of the workpiece, and the lower surface of the workpiece is attached to the shaping tool; fourthly, a cooling water device is started to carry out cooling operation, and the workpiece and the shaping tool are cooled to the normal temperature; and fifthly, the workpiece retreats from the hydraulic machine and is taken out, and the heating shaping process is ended.
Description
Technical field
The present invention relates to foundry goods shaping process field, be specially a kind of heating shaping methods.
Background technology
Along with the development of science and technology and the requirement of energy-saving and emission-reduction, the wall thickness of foundry goods does thinner and thinner, brings new challenge to casting producer.Existing common shaping operation is all manually operate, and casting section thickness is thinning, and casting dimension is just difficult to ensure, easy distortion, and common cold shaping process cannot put in place in a shaping, because foundry goods wall is thinner, rebound more serious, need shaping repeatedly, production efficiency is low.
Summary of the invention
In order to solve the problem, the invention provides a kind of heating shaping methods, it can realize a shaping and put in place, greatly raises the efficiency.
Its technical scheme is such: a kind of heating shaping process, and it is characterized in that, it comprises the following steps:
(1) on base, shaping tooling is installed;
(2) will the workpiece heat of shaping be needed to 800-850 DEG C, then the workpiece after heating is positioned on shaping tooling;
(3) upper surface of primer fluid press pressure workpiece makes workpiece lower surface and shaping tooling fit;
(4) start chilled water unit and carry out cooling down operation, workpiece and shaping tooling are cooled to normal temperature;
(5) exit hydraulic press, take out workpiece, heating reforming process terminates.
It is further characterized in that, shaping tooling is assembled by polylith working plate, and working plate is screwed on base;
In step (2), workpiece is heated by electric furnace or radio-frequency induction coil;
In step (4), start chilled water unit and carry out cooling down operation for be directly sprayed onto on workpiece and shaping tooling by water pipe by cooling water;
After taking out workpiece, operation is dried up to workpiece.
After adopting method of the present invention, by heating, workpiece is easily out of shape, pressure workpiece and shaping tooling have been fitted shaping, carry out cooling postforming, achieve a shaping and put in place, substantially increase efficiency.

Fig. 1 is shaping tooling front view;
Fig. 2 is shaping tooling top view.
Detailed description of the invention
A kind of heating shaping process, it is characterized in that, it comprises the following steps:
(1) on base 1, shaping tooling 2 is installed;
(2) will the workpiece heat of shaping be needed to 800-850 DEG C, then the workpiece after heating is positioned on shaping tooling 2;
(3) upper surface of primer fluid press pressure workpiece makes workpiece lower surface and shaping tooling 2 fit;
(4) start chilled water unit and carry out cooling down operation, workpiece and shaping tooling 2 are cooled to normal temperature;
(5) exit hydraulic press, take out workpiece, heating reforming process terminates.
See Fig. 1, shown in Fig. 2, shaping tooling is assembled by 8 pieces of working plates, and working plate is screwed on base 1.
In step (2), workpiece is heated by electric furnace or radio-frequency induction coil, and heating is convenient and heating effect is good.
In step (4), start chilled water unit and carry out cooling down operation for be directly sprayed onto on workpiece and shaping tooling by water pipe by cooling water, simple to operation.Because cooling water is directly sprayed, after taking out workpiece, need to dry up operation to workpiece.
