Description
Technical field
The present invention relates to a kind of slide block and dieing machine.
Background technology
At present in mechanical press's structure, slide block is requisite important moving component, and being both that punching press is reciprocating holds
Row part is also the upper table that stamping mold is installed.When punch press works, first the upper mould of mould is fixed on slide block, under mould
Mould portion is fixed on the table；Punch is installed in the upper mould of mould, die is installed in the lower mould of mould；Start punch press, mould
The lower mould of tool is maintained static with workbench, and the upper mould of slide block driven mold is reciprocating, while stamping material passes through feeder
Send in mould, punch forming is realized in the presence of concave-convex mold.
In actual production, in order to reduce production cost improve production efficiency, the actual production punching press speed of high velocity ram machine
Degree has brought up to more than 1000 beats/min, as slide block and upper mould remain and run up that linear velocity has reached 1m/s;Punching
High-speed friction between the punch of mould in journey and stamping material is pressed through, substantial amounts of heat is produced, although punching press material in punching course
The material lubricating oil being coated with material has taken away a part of heat, but still also substantial amounts of heat has been delivered to upper mould by punch
On slide block.Meanwhile, because of environment and safety requirements, high velocity ram machine is typically fitted with safety door and sound proof box, air in punch press
Relatively slowly, rear slider and upper mould temperature can gradually rise for a period of time for punching press for poor fluidity, slide block and the radiating of upper mould, and the temperature of upper mould
Degree rising can cause Male Die Size to expand, and affect precision and the mold use life-span of product, so as to reduce whole production efficiency,
Increase the production cost of enterprise.And it is current, for this problem, not preferably solution proposition, if on mould
One complicated cooling device of design, can greatly improve the manufacture difficulty and cost of mould, it is clear that be detrimental to what is promoted the use of.
Slide block belongs to cast member, casting when design a cavity of the both sides with through hole, in existing punch press, not to slide block this
The structure of itself has the improvement application of correlation, and the heavier-weight of slide block itself, after being installed on punch press, typically not will recognize that
Certain production needs are met by transforming to which again.
The content of the invention
In order to solve above-mentioned dieing machine in operation due in upper mould plug temperature raise deform stamping products
Problem, it is considered to the slide block to being directly connected to upper mould is reequiped, make improvement rear slider have can realize itself cooling drop
The structure of temperature, and then it is reduced the temperature of the upper mould being directly fixedly connected with slide block, it is to avoid the plug temperature inside upper mould
The problem for causing stamping products precision of poor quality low after rising.
The technical scheme that the present invention is provided is as follows：A kind of slide block, for dieing machine in, be provided with chamber in the slide block
Body, the front and back of the slide block are respectively equipped with the through hole communicated with cavity, and the front of the slide block is provided with and is covered in through hole
On first baffle, the back side of the slide block is provided with the second baffle being covered on through hole, the first baffle, second baffle and
Cavity constitutes coolant memory block, and the top of the second baffle is provided with cooling liquid inlet, and the bottom of the second baffle sets
It is equipped with cooling liquid outlet.
Further, coolant circulation unit is provided between the cooling liquid inlet and cooling liquid outlet.
Further, between the front of the slide block and first baffle and slide block the back side and second baffle between be all provided with
It is equipped with sealing ring.
The invention further relates to a kind of dieing machine, including footstock, middle abutment body and base, the middle abutment body internal upper part sets
The slide block of said structure is equipped with, and bottom is provided with workbench in the middle abutment body, mould is provided between the slide block and workbench
Tool, the mould include upper die and lower die, and the upper mould is fixedly connected with slider bottom, and the lower mould is relatively fixed with upper mould
Arrange on the table.
A kind of slide block of the present invention, is improved on the basis of existing structure, by first is arranged on slide block
Baffle plate and second baffle, first baffle and second baffle enclose a coolant memory block with the cavity in slide block jointly, cooling
Liquid is circulated turnover by the inlet and outlet on second baffle, can reduce the temperature of slide block well, and then make and cunning
In the upper mould and upper mould of block connection, the temperature of punch is reduced, it is ensured that the qualification rate of stamping products.It is mounted with the high speed of above-mentioned slide block
Accurate punching machine, as what slide block in operation can continue further realizes to punch in upper mould and upper mould to itself cooling down
Cool, solve plug temperature in the in the past upper mould of presence and raise and cause the ropy difficult problem of stamping products, not only carry
High production efficiency, even more greatly reduces the production cost of enterprise.

Circle 5, for guaranteeing seamless installation between first baffle and second baffle and shoe surface, it is to avoid leakage.
The major advantage of a kind of slide block of the present invention and dieing machine is：By changing to existing slide block structure
Enter, the slide block after improvement is made after being installed in dieing machine, lasting in punch press operation process itself can be entered
Row cools, and then the temperature of the upper mould for being provided with punch for making directly to be fixedly connected with slide block is reduced, it is ensured that stamping products
Quality.The concrete actual influence reference table 1 to upper mould temperature, wherein staff have recorded punch press under each drawing velocity
After two hours of operating, the temperature value in the middle part of slider bottom plate and in the middle part of upper mould convex mould stamping surface, described slider bottom plate are arranged
Junction between slide block and upper mould, after plug temperature is raised, upper mould temperature is also raised, and the temperature of slider bottom plate is risen therewith
Height, and then the temperature of slide block is also with rising, therefore, the temperature changing trend of slider bottom plate represents the temperature change of slide block and becomes
Gesture.
Table 1
According to the Data Comparison in upper table 1, by cooling down to slide block, the upper mould convex mould stamping surface temperature of operation is made
When drawing velocity is less than 800 beats/min, temperature is held in less than 40 DEG C, is so greatly lowered the unqualified of product
Rate, improves production efficiency.
In a word, presently preferred embodiments of the present invention is the foregoing is only, it is not to limit the present invention, all in the present invention
Spirit and principle within any modification, equivalent and the improvement made etc., should be included in protection scope of the present invention it
It is interior.
