Abstract

The present invention provides a kind of lock formula hydraulic plate shears, including rack, the workbench being located in rack, upper and lower knife rest, upper and lower blade, electrical system, hydraulic system, digital control system and the clearance adjustment mechanism being respectively and fixedly installed on upper and lower knife rest, described cutting is erected at workbench top;The cutter and bottom knife is made of the cemented carbide material of high-hardness wear-resistant, and the cemented carbide material is prepared using following steps:1)Using tungsten-carbide powder and super-fine cobalt powder as raw material, powder is prepared into using planetary ball mill;2)Ultra-fine cemented carbide is made by compression moulding, hydrogen degumming and vacuum-sintering.The lock formula hydraulic plate shears of the present invention can be used for a long time due to cutter made of the material with hardness high wear resistance, need not often be replaced.

Description

A kind of lock formula hydraulic plate shears
Technical field
The present invention relates to a kind of lock formula hydraulic plate shears, belong to machine tool technology field.
Background technology
Plate shearing machine is to be done reciprocating linear motion to shear the machine of plank with relatively another blade of a blade.It is to borrow in movement Cutter and fixed bottom knife shearing force is applied to the sheet metal of various thickness, makes plate using rational gap blade Material presses required size fracture separation.Plate shearing machine belongs to one kind in metal forming machinery, and main function is exactly metal-working industry. Product is widely used in needed for the offer of the industries such as aviation, light industry, metallurgy, chemical industry, building, ship, automobile, electric power, electric appliance, decoration Special-purpose machinery and complete set of equipments.
The operation principle of plate shearing machine is that the cutter of plate shearing machine is fixed on knife rest, and bottom knife is fixed on the table.Work Make that retainer ball is installed on platform, in order to which plate is not scratched when sliding over.Back material stopping is positioned for plate, position It is adjusted by motor.Binder cylinder is for compressing plate, to prevent plate from being moved in shearing.Guardrail is safety device, to prevent Industrial accident only occurs.Nitrogen is generally leaned in backhaul, and speed is fast, and impact is small.
Since the blade of plate shearing machine is using frequent, when cutting, is easy to wear, replaces trouble, affects the use of plate shearing machine.
Invention content
The purpose of the present invention is overcome the deficiencies of the prior art and provide a kind of lock formula hydraulic plate shears.
The present invention lock formula hydraulic plate shears, including rack, be located in rack workbench, upper and lower knife rest, fix respectively Upper and lower blade, electrical system, hydraulic system, digital control system and clearance adjustment mechanism on upper and lower knife rest, it is described It cuts and is erected at workbench top;
The cutter and bottom knife is made of the cemented carbide material of high-hardness wear-resistant,
The cemented carbide material is prepared using following steps:
1)Using tungsten-carbide powder and super-fine cobalt powder as raw material, powder is prepared into using planetary ball mill;
2)Ultra-fine cemented carbide is made by compression moulding, hydrogen degumming and vacuum-sintering.
Preferably,
The step 2)The temperature of middle vacuum-sintering is 1450 degrees Celsius.
The lock formula hydraulic plate shears of the present invention can due to cutter made of the material with hardness high wear resistance It is used for a long time, need not often replace.
Specific implementation mode
Embodiment 1
The present invention lock formula hydraulic plate shears, including rack, be located in rack workbench, upper and lower knife rest, be fixedly mounted respectively Upper and lower blade, electrical system, hydraulic system, digital control system and clearance adjustment mechanism on upper and lower knife rest, described cuts It is erected at workbench top;
The cutter and bottom knife is made of the cemented carbide material of high-hardness wear-resistant,
The cemented carbide material is prepared using following steps:
1)Using tungsten-carbide powder and super-fine cobalt powder as raw material, powder is prepared into using planetary ball mill;
2)Ultra-fine cemented carbide is made by compression moulding, hydrogen degumming and vacuum-sintering.
The step 2)The temperature of middle vacuum-sintering is 1450 degrees Celsius.
