Technical field
The present invention relates to brake block making apparatus technical field, specifically a kind of mechanically synchronous low energy consumption hot pressing
Machine.
Background technology
The course of work of traditional hot press for making brake block is as follows, is filled out first into the cavity plate of middle form unit
Material.Then mold, i.e., punch-pin and cavity plate under the action of master cylinder together synchronize move upwards, until the upper plane of cavity plate with it is upper
The lower plane of moulded board is in contact.Then it suppresses, master cylinder pressurization carries out heating compacting to raw material.It mainly deposits in this course
Following several respects the problem of：
First, during molding, punch-pin and cavity plate rise together to be controlled by master cylinder, since master cylinder also has
One main function is suppressed raw material.In order to meet pressure requirements when compacting, the cylinder diameter of master cylinder is generally large.And
Due to the space of mold changing to be reserved, during molding, punch-pin climb synchronous with cavity plate is long, leans on master cylinder
It drives the punch-pin speed that synchronize moves upwards or rise with cavity plate can be very slow, has seriously affected processing efficiency or will
The power for increasing the discharge capacity and motor of pump but will certainly increase the energy consumption of equipment in this way to improve the speed risen, operation at
This raising.
Second, due to punch-pin is synchronous with cavity plate rise before, be added to raw material in warp-wise cavity plate, thus in order to avoid
Raw material is leaked or is overflowed, and punch-pin will keep during rising stringent synchronous with cavity plate.Traditional hot press all passes through
Hydraulic control punch-pin is synchronous with cavity plate, and this control mode not only cannot be guaranteed punch-pin and cavity plate stringent synchronization, but also increase
The complexity of hydraulic system, increases the manufacturing cost of equipment.
Invention content
In view of the above-mentioned problems, the present invention provides a kind of mechanically synchronous low energy consumption hot press, which can not only
Enough ensure the stringent synchronous rising of punch-pin and cavity plate, and ensure punch-pin and cavity plate can rapid increase under the premise of, reduction
The discharge capacity of pump, low energy consumption.
