Abstract
The utility model relates to a copper bar hydraulic cold-drawing machine, which comprises a lathe bed, a master cylinder, a piston rod, a cart with a gripper, a programmable logic controller and an approach switch which is arranged at the tail of the lathe bed. The copper bar hydraulic cold-drawing machine is characterized in that the front part of the approach switch of the tail of the lathe bed is additionally provided with an approach switch; the added approach switch is connected with a button switch and the programmable logic controller in sequence and is connected with a support fixedly connected with the lathe body. The utility model has the advantages that the approach switch connected with the programmable logic controller is installed, and after the front end of the headstock of the cart sends a signal to the approach switch and feeds backs the signal to the programmable logic controller, the cart automatically stops. The rebound of the pull of the cart when in bar cutting is avoided to make a copper bar not generate the condition that the bar head is damaged. Accordingly, when the copper bar is cut each time, 160mm -170mm of raw materials can be saved; through calculation, when the copper bar is drawn every 35times-37 times, a 6m copper bar of standard specified length can be saved.
Description
Technical field
The utility model belongs to hydraulic pressure cold drawing machine, relates in particular to a kind of copper bar head side of can avoiding and impression and crooked copper bar hydraulic pressure cold drawing machine occur.
Background technology
It is the drawbench of power that the copper bar hydraulic drawbench adopts with hydraulic pressure.Copper bar hydraulic drawbench (as 63 tons of drawbench commonly used) pulling capacity is big, stable action.By the piston rod in the master cylinder, the clamping that drives front end pulls a cart to do the reciprocating motion of front and back, is achieved the drawing of finished product copper bar.This drawbench draws copper bar, utilize hydraulic coupling to make to pull a cart dop to clamp copper bar, move backward under the effect of hydraulic coupling by the piston rod in the master cylinder again, copper bar is pulled out from mould, when pulling a cart to walk to caudal end after the stop motion, adopt protrusive sawing directly to cut off copper bar in the die holder position this moment.Because there is certain force of strain in the copper bar of traction, when not being cut off fully, just broken copper bar, and this moment, the head at copper bar produced a moment, and copper bar and mould calibrating strap are clashed into, and copper bar vestige and bending occur at the mould outlet place.Cause every copper bar after drawing, must many sawings fall the copper bar head of 160-170mm, caused raw-material waste.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of copper bar hydraulic pressure cold drawing machine is provided, and can avoid copper bar head side cut to occur, reduces each copper bar tip lengths of shearing, and can save the copper raw material of 160-170mm.
The utility model for achieving the above object, by the following technical solutions: a kind of copper bar hydraulic pressure cold drawing machine, comprise the pulling a cart of lathe bed, master cylinder, piston rod, strap clamp mouth, programmable logic controller (PLC) and be located at the lathe bed afterbody near switch, it is characterized in that: described lathe bed afterbody is set up one near switch near the front portion of switch, described increasing newly is connected with programmable logic controller (PLC) with press button successively near switch, and is connected with the support that is fixed in lathe bed.
Described newly-increased installation site near switch is the 20-30mm+ dolly length of wagon to be basic point near the position of the switch.
Beneficial effect: be provided be connected with programmable logic controller (PLC) near switch, when the headstock front end of pulling a cart near signal of switch and after feeding back to programmable logic controller (PLC), make the automatic stopping of pulling a cart.Pull a cart when avoiding the row of the cutting bounce-back of pulling force, the situation of file leader's damage no longer appears in copper bar.Thus, when shearing copper bar, can save 160 to 170mm raw materials, every as calculated drawing 35 to 37 times just can save the copper bar of a 6m standard scale at every turn.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the partial top view of Fig. 1.
The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure, a kind of copper bar hydraulic pressure cold drawing machine, a kind of copper bar hydraulic pressure cold drawing machine, comprise lathe bed 1, master cylinder (not shown), piston rod 2, strap clamp mouth pull a cart 3, programmable logic controller (PLC) 7 and be located at the lathe bed afterbody near switch 6, described lathe bed afterbody is set up one near switch 5 near the front distance position of switch, described increasing newly is connected with programmable logic controller (PLC) with button 8 switches successively near switch, and is connected with the support that is fixed in lathe bed.Described newly-increased installation site near switch is the 20-30mm+ dolly length of wagon to be basic point near the position of the switch.
Operation principle: behind the row that pulls a cart, arrive after the caudal end, when the vehicle tail end of pulling a cart is given near 6 one signals of switch and to feed back to programmable logic controller (PLC) be stop sign.Pull a cart and to stop.At this moment, the operator presses the button 8 on the console, what make newly-increased normally open is in normally closed duty near switch 5, simultaneously, the operator presses the oil cylinder play button 9 that moves ahead, and the control oil cylinder drives again pulls a cart to move ahead 20 to 30mm, when the front end of pulling a cart drives to newly-increased during near switch 5 places, newly-increased to feed back to programmable logic controller (PLC) near switch be stop sign, makes the automatic stopping once more of pulling a cart.Can eliminate the hydraulic coupling of drawing copper bar first.When shearing, just do not have the reaction force that causes the copper bar damage again, second can be not excessive because of forward travel distance yet, cause the copper bar that draws moulding to curl.After the row of pulling a cart retreats into caudal end, locate about headstock front end 30mm pulling a cart, increase by one near switch, to be connected near the PLC of switch with the master control of equipment own, signal near switch can be fed back on the PLC of this master control, PLC by this master control sends signal again, makes the automatic stopping of pulling a cart, with the accurate distance of guaranteeing to pull a cart to move ahead.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
