Abstract
The invention provides a stress field thermal relaxation optimized hydraulic plate shearing machine. The stress field thermal relaxation optimized hydraulic plate shearing machine comprises a machine frame, a left hydraulic cylinder sleeve, a right hydraulic cylinder sleeve, a left hydraulic rod, a right hydraulic rod, a left side roller bearing seat, a right side roller bearing seat, a left side roller and a right side roller, wherein the left hydraulic cylinder sleeve and the right hydraulic cylinder sleeve are arranged on the two sides of the machine frame, the left hydraulic rod and the right hydraulic rod are connected with the left hydraulic cylinder sleeve and the right hydraulic cylinder sleeve respectively, the left side roller bearing seat and the right side roller bearing seat are connected with the left hydraulic rod and the right hydraulic rod respectively, and the left side roller and the right side roller are fixed to the left side roller bearing seat and the right side roller bearing seat respectively; an oil tube and an oil tube connector are connected between an upper tool rest and the hydraulic cylinder sleeves, and the oil tube connector is a high-pressure steel wire braided rubber hose and is flexibly connected with the oil tube and the upper tool rest; the high-pressure steel wire braided rubber hose is composed of an inner rubber layer, an outer rubber layer and an inner steel wire braided layer, the inner rubber layer is 1-3 mm thick and made of nitrile rubber, and the outer rubber layer adheres to an enhancement layer to play a role of protection and is made of chloroprene rubber. By adopting the stress field thermal relaxation optimized oil tube connector, the occurrence of stress field thermal relaxation is reduced.
Description
Technical field
The present invention relates to the hydraulic plate shears that a kind of stress field hot wire-CVD is optimized, belong to plate shearing machine technical field.
Background technology
Plate shearing machine does reciprocating linear motion with a blade another blade relative to shear the machine of sheet material.Be borrow in the cutter moved and fixing bottom knife, adopt rational gap blade, shearing force is applied to the sheet metal of various thickness, make sheet material by required size fracture separation.Plate shearing machine belongs to the one in metal forming machinery, and Main Function is exactly metal-working industry.Product is widely used in the industries such as aviation, light industry, metallurgy, chemical industry, building, boats and ships, automobile, electric power, electrical equipment, decoration and provides required special-purpose machinery and complete set of equipments.Its operation principle is as follows: the cutter of plate shearing machine is fixed on knife rest, and bottom knife is fixing on the table.Workbench is provided with retainer ball, so that be not scratched during the sliding above of plate.Back material stopping is used for plate location, and position is regulated by motor.Binder cylinder, for compressing plate, moves when shearing to prevent plate.Guardrail is safety device, to prevent industrial accident.Backhaul is generally by nitrogen, and speed is fast, impacts little.
Stress field hot wire-CVD, i.e. creep, solid material is keeping under the condition that stress is constant, the phenomenon that strain extends in time and increases.It is different from plastic deformation, and plastic deformation just occurs usually after stress exceedes elastic limit, as long as and the action time of creep stress quite long, it stress be less than elastic limit apply power time also can occur.Many materials (as metal, plastics, rock and ice) all show the character of creep under certain condition.Due to creep, material is in certain instantaneous stress state, and generally not only instantaneous with this distortion is relevant, and relevant with the deformation process before this is instantaneous.Many engineering problems all relate to creep.The fastenings of the hydraulic plate shears under high temperature, the elasticity pre-tight stress of its inside is decayed in time, can cause sealing leak or the accident that gets loose.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, the hydraulic plate shears that a kind of stress field hot wire-CVD is optimized is provided.
The hydraulic plate shears that stress field hot wire-CVD of the present invention is optimized, comprise frame, be located at a left side for frame both sides, right hydraulic cylinder, respectively with a left side, the left side that right hydraulic cylinder is connected, right hydraulic stem, respectively with a left side, the left side that right hydraulic stem is connected, right roller bearing block, be separately fixed at a left side, a left side on right roller bearing block, right roller, be located at the left side in the middle of frame, right trunnion shaft curved bar and lower roll crank, respectively with a left side, the left side that right trunnion shaft curved bar is connected, right trunnion shaft link rod, the lower roll link rod be connected with lower roll crank, the bottom roll bearing block be connected with lower roll link rod, the top roll being fixed on the lower roll on bottom roll bearing block and being fixed on above bottom roll bearing block, oil pipe and oil connection is connected with between described upper tool post and hydraulic cylinder,
