Description
Technical field
The present invention relates to brake block making apparatus technical field, specifically a kind of mechanical 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 matched moulds, i.e. punch-pin and the cavity plate synchronous motion upwards together in the presence of master cylinder, until the upper plane of cavity plate with it is upper
The lower plane of moulded board is in contact.Then suppress, master cylinder pressurization carries out heating compacting to raw material.Mainly deposit in this course
The problem of following several respects：
First, during matched moulds, it is by master cylinder control, because master cylinder also has that punch-pin and cavity plate rise together
One main function is that raw material is suppressed.In order to meet pressure requirements during compacting, the cylinder diameter of master cylinder is generally large.And
Due to the space of mold changing to be reserved, therefore during matched moulds, punch-pin and the synchronous climb of cavity plate are long, by master cylinder
Punch-pin and the synchronous motion upwards of cavity plate are driven, or the speed risen can be very slow, processing efficiency has been had a strong impact on, otherwise will
The discharge capacity of pump and the power of motor are increased, to improve the speed of rising, but will certainly so increase the energy consumption of equipment, run into
This raising.
Second, due to before punch-pin and cavity plate synchronously rise, with the addition of raw material in warp-wise cavity plate, therefore in order to avoid
Raw material seepage or spilling, punch-pin and cavity plate will keep strict synchronization during rising.Traditional hot press all passes through
Hydraulic control punch-pin and cavity plate are synchronous, and this control mode is not only it is impossible to ensure that punch-pin and cavity plate stringent synchronization, and increase
The complexity of hydraulic system, increases the manufacturing cost of equipment.
The content of the invention
In view of the above-mentioned problems, the invention provides a kind of mechanical synchronous low energy consumption hot press, the hot press can not only
Enough ensure the strict synchronous rising of punch-pin and cavity plate, and ensureing that punch-pin and cavity plate can be on the premise of rapid increases, reduction
The discharge capacity of pump, energy consumption is low.
The technical scheme adopted by the invention to solve the technical problem is that：
A kind of mechanical synchronous low energy consumption hot press, including support body, described support body include upper bed-plate, middle template, under
Template, lower bottom base and column, described upper bed-plate and lower bottom base are fixedly connected with column respectively, described middle template and lower template

The upper mould for fixing upper molded plate is provided with described upper bed-plate to heat in fixation kit, described middle template
It is provided with the middle mould for fixing cavity plate and heats to be provided with fixation kit, described lower template and adds for the lower mould of solid punch
Heat fixation component, master cylinder is provided between described lower bottom base and lower template；
Auxiliary cylinder is provided between the middle template and lower bottom base, the cylinder body of the auxiliary cylinder is fixed with lower bottom base to be connected
Connect, the piston rod of described auxiliary cylinder is fixedly connected by latch segment with described middle template；
Synchronous pull rod is provided between described middle template and lower template, lower end and the lower template of the Synchronous pull rod are fixed
Connection, the upper end of the Synchronous pull rod protrudes from described middle template and is slidably connected with described middle template, the synchronous drawing
The upper end of bar is provided with limited block.
Further, the upper cover of piston rod of the auxiliary cylinder is provided with synchronous sleeve, and when the upper end of the synchronous sleeve
When face and the lower surface of latch segment are adjacent to, there is 2-3mm spacing between the pedestal of the lower surface of the cavity plate and the punch-pin.
Further, it is located on described Synchronous pull rod and is provided with mold changing cushion block between described limited block and middle template.
Further, it is provided with U-type groove on described mold changing cushion block.
Further, the groove for accommodating the mold changing cushion block is provided with described middle template.

The beneficial effects of the invention are as follows：
1st, auxiliary cylinder is set respectively by the both sides in master cylinder, during matched moulds, driven by auxiliary cylinder.It is main
The piston rod of oil cylinder is passive to stretch out under the drive of auxiliary cylinder, the passive oil suction of rodless cavity of master cylinder, without pump actively
To the rodless cavity fuel feeding of master cylinder, the discharge capacity of pump greatly reduces, energy consumption is reduced.
2nd, by setting Synchronous pull rod between middle template and lower template, synchronizing sleeve is set in the upper cover of piston rod of auxiliary cylinder
Cylinder, ensures that punch-pin and cavity plate are synchronized with the movement during matched moulds, synchronism is relatively reliable by mechanical hard spacing mode.
3rd, positioned during pushing-off product brake block by synchronous sleeve, it is to avoid occur between punch-pin and cavity plate
Rigid collision, greatly extends the service life of punch-pin and cavity plate, reduces maintenance cost.
4th, by setting mold changing cushion block on Synchronous pull rod, mold changing cushion block is removed when needing mold changing, biography is changed
The positioning method of the use inductive switch of system, not only increases equipment reliability of operation (inductive switch is easily damaged), and
Reduce the complexity of control system.
5th, U-type groove is provided with described mold changing cushion block, facilitates the installation and dismounting of mold changing cushion block.
