Abstract
The utility model discloses a cold drawing device, which comprises a frame, be provided with the square chamber that holds in the frame, square four sides that hold the intracavity are provided with a U -shaped groove respectively, the U -shaped inslot is provided with one and can stretches into the square roller frame that holds the intracavity, every be provided with a roller on the roller frame, four roller cooperation back constitutes be convenient for square steel or the square rectangle die cavity that passes through of managing, wherein, the rear end of roller frame is passed through the lead screw and is set up the adjusting device that feeds in the frame outside connects. This device adopts four rollers to form square holes and substitutes original moulds, and the big I of square hole adjusts according to actual size, and it can only machining unit specification product to change original mould, has enlarged the range of application.
Description
Technical field
The utility model is related to a kind of cold-drawing device.
Background technology
Traditional technique for square steel or square tube carry out cold-drawn when, cold-drawn mould mainly using fixed, prick by square steel or square tube
Head carries out drawing in the presence of pulling capacity by cold-drawn mould after, such mould and drawable material contact surface be constantly subjected to extrude and
Abrasion so that cold-drawn equipment life shortens, loss become big.
Utility model content
The utility model purpose is to provide a kind of cold-drawing device for the defect that prior art is present.
The utility model for achieving the above object, is adopted the following technical scheme that：A kind of cold-drawing device, it is including frame, described
Square accommodating chamber is provided with frame, and four sides in the square accommodating chamber are respectively arranged with a U-lag, the U-shaped
A roller mount that can be extend in the square accommodating chamber is provided with groove, is provided with a roller in each described roller mount；
Four rollers constitute the rectangle mold cavity for being easy to square steel or square tube to pass through after coordinating；Wherein, the rear end of the roller mount passes through
Screw mandrel is connected with the feeding adjusting apparatus for being arranged on the shell outside.
The beneficial effects of the utility model：This device forms square hole using four rollers and substitutes original mould, and square hole
Big I adjusted according to actual size, change original mould can only machining cell specification product, expand range of application；Separately
Outward, in Cold Drawing Process, the relative motion of mould and material belongs to sliding friction, quick abrasion, mould loss to original mould
Greatly, and as abrasion aggravation, mold materials have loss, cold-drawn hole can increase, and the precise decreasing of drawing is mainly transported after just having roller
It is rolling friction to move, and roll wear is little, and life-span length, precision are also guaranteed；In addition, feeding adjusting apparatus can adopt hydraulic pressure or
Leading screw etc., can conveniently form automatic mechanism.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Shown in Fig. 1, it is related to a kind of cold-drawing device, including frame 1, in the frame 1, is provided with square accommodating chamber 11, it is described
Four sides in square accommodating chamber 11 are respectively arranged with a U-lag 12, be provided with one and can extend into institute in the U-lag 12
The roller mount 2 in square accommodating chamber 11 is stated, a roller 4 in each roller mount 2, is provided with；Four rollers 4 are constituted just after coordinating
In the rectangle mold cavity that square steel or square tube 5 pass through；Wherein, the rear end of the roller mount 2 passes through screw mandrel and is arranged on outside the frame 1
The feeding adjusting apparatus 3 of side connect.
Operation principle：According to size after the shaping of the square steel (square steel) of drawing, starting feeding adjusting apparatus 3 reaches roller 4
Correct position, then square steel (square tube) prick head and extend through in the square hole that four rollers are formed, then power set apply to draw to pricking head
Pull out force F, pulling capacity F and square hole normal parallel, make square steel (square tube) tension stress, when tension exceedes Materials Yield Limit value
Afterwards, there is plastic deformation, under the shaping operation of four rollers, square steel (square tube) is elongated, and in Cold Drawing Process, roller is with drawing
Pull out material rolling.
Preferred embodiment of the present utility model is the foregoing is only, it is not to limit the utility model, all in this practicality
Within new spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in guarantor of the present utility model
Within the scope of shield.
