Abstract

The utility model provides a drawing machine with a strip-breakage protection function. A drawing head is arranged at one end of a drawing beam assembly, a fixed head is arranged at the other end of the drawing beam assembly, a chuck on the drawing head corresponds to a chuck on the fixed head for clamping a hot rolled plate, two hydraulic cylinders are fixed at the outer end of the drawing beam assembly on one side of the drawing head, two hydraulic rods are arranged at the upper end of the drawing beam assembly on one side of the drawing head and connected with two ends of the drawing head, the two hydraulic rods are connected with the two hydraulic cylinders arranged symmetrically, and two impact buffer hydraulic cylinders are arranged on the drawing beam assembly in front of the chuck on the fixed head. The drawing machine is simple in structure, reliable in strip-breakage protection and convenient to install and maintain; devices can be protected from being damaged when strips are broken and loss to production caused by strip breakage is greatly reduced.

Description

Stretching-machine with broken belt protector function
Technical field
The utility model relates to a kind of stretching-machine with broken belt protector function, belongs to the stretching-machine technical field.
Background technology
The aluminium alloy plate material stretching machine is one of key equipment of production Aero-Space usefulness drawing plate.Broken belt protector be stretching-machine in process of production suddenly fracture of sheet material to the safeguard measure of equipment itself.The broken belt protector measure is that stretching-machine is requisite, if stretching-machine broken belt protector measure imperfection, when the sheet material broken belt occurs; the damaged condition of equipment can't be estimated; gently then equipment downtime maintenance, heavy then Equipment Foundations are by heavy damage, and be very huge to the loss that production brings.When there is crackle in the limit section of hot rolled plate; in the process of uneven pulling, very easily produce belt phenomenon; when broken belt occurs; fixed chuck and movable chuck can produce very large kinetic energy; according to law of conservation of energy; this part kinetic energy must have corresponding safeguard measure to remove to offset this part energy, otherwise can produce greatly harm to equipment, and what impact was produced normally carries out.
Summary of the invention
The purpose of this utility model be for solve existing stretching-machine in process of production the sheet material fracture bring the problem of loss to production, and then provide a kind of stretching-machine with broken belt protector function.
The purpose of this utility model is achieved through the following technical solutions:
A kind of stretching-machine with broken belt protector function; comprise: two hydraulic cylinders; two hydraulic stems; stretching head; the stretching beam assembly; gland and two damping of shocks hydraulic cylinders; described stretching head is arranged on an end of stretching beam assembly; gland is arranged on the other end of stretching beam assembly; chuck on the stretching head is corresponding with the chuck on the gland for the clamping hot rolled plate; two hydraulic cylinders all are fixed on the outer end of the stretching beam assembly of the first side that stretches; two hydraulic stems all be arranged on the first side that stretches the stretching beam assembly the upper end and be connected with the two ends of stretching head; hydraulic stem is connected with hydraulic cylinder; described two hydraulic cylinders are symmetrical arranged, and two damping of shocks hydraulic cylinders are arranged on the stretching beam assembly of gland upper grip front side.
The utility model is simple in structure, and broken belt protector is reliable, and is convenient for installation and maintenance.Can be without prejudice by protection equipment when broken belt occurs, greatly reduce to resolve to bring and produce the loss that brings.
Broken belt frequency when stretching-machine is normally produced when not increasing the broken belt protector measure is approximately calculated for 20 times/month, is every year 240 times.Situation according to broken belt is different, and the time of resuming production after the each shutdown of equipment is 480~960 hours every year between 2~4 hours/time.After increasing the broken belt protector measure, the time of resuming production after the each shutdown of equipment is 72~240 hours every year between 0.3~1 hour/time.Than front saving 480-72=408 downtime hour, 960-240=720 hour.Namely save 408~720 hours.
According to stretching-machine regular size production calculation, 5 tons/hour of stretching-machines, drawing plate increase the economic benefit of creating after the broken belt protector measure according to average 40000 yuan/tons of calculating:
40000 * 5 * (408~720)=81600000~144000000 yuan.
Description of drawings
Fig. 1 is a kind of structural representation with stretching-machine of broken belt protector function of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail: the present embodiment is implemented under take technical solutions of the utility model as prerequisite, has provided detailed embodiment, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1; a kind of stretching-machine with broken belt protector function that the present embodiment is related; comprise: two hydraulic cylinders 1; two hydraulic stems 2; stretching head 3; stretching beam assembly 4; gland 7 and two damping of shocks hydraulic cylinders 9; described stretching head 3 is arranged on an end of stretching beam assembly 4; gland 7 is arranged on the other end of stretching beam assembly 4; chuck 8 on the stretching head 3 is corresponding for clamping hot rolled plate 5 with the chuck 6 on the gland 7; two hydraulic cylinders 1 all are fixed on the outer end of the stretching beam assembly 4 of stretching head 3 one sides; two hydraulic stems 2 all be arranged on stretching head 3 one sides stretching beam assembly 4 the upper end and be connected with the two ends of stretching head 3; hydraulic stem 2 is connected with hydraulic cylinder 1; described two hydraulic cylinders 1 are symmetrical arranged, and two damping of shocks hydraulic cylinders 9 are arranged on the stretching beam assembly 4 of gland 7 upper grips 6 front sides.
Operation principle: when broken belt occurs when, all tensile energy sudden outbursts, stretching head and gland and stretching beam assembly have mobile tendency.At the stretching beam assembly of stretching-machine vibration absorber is set and absorbs the energy that discharges, the chuck of restriction stretching-machine is mobile in allowed band.
Realize regulating the feeding of damping of shocks hydraulic cylinder by plunger rod.Plunger rod has hole, and being used for is having oil-feed under the pressure.When broken belt occurs when, gland and stretching beam assembly have a small amount of movement, the hydraulic circuit of regulating the damping of shocks hydraulic cylinder is closed, the working space of regulating the damping of shocks hydraulic cylinder contacts with the brake fluid pressure loop, make gland pressure maximum reach 420bar by relief valve, the stretching head maximum pressure reaches 600bar.This function is to realize by the distributor of regulating the damping of shocks hydraulic cylinder.The pressure of regulating the damping of shocks hydraulic cylinder guarantees that by the oil circuit in the braking pipe network braking of two cell positions is limited in maximum 150mm.Gland and stretching beam assembly are furnished with the damping of shocks hydraulic cylinder, be used for impact-absorbing and device replied is arrived the center.By the again centering of equipment, hydraulic cylinder begins normal operation.
The above; it only is the better specific embodiment of the utility model; these specific embodiment all are based on the different implementations under the utility model general idea; and protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
