Abstract
The invention relates to a clamp of a conical expansion-sleeve type steel bar cold drawing machine. The clamp comprises an end cover (1), an inner expansion sleeve (2) and an outer expansion sleeve (3), wherein the inner expansion sleeve (2) is arranged inside the outer expansion sleeve (3); the end cover (1) is arranged at the upper part of the outer expansion sleeve (3) and is connected with outer expansion sleeve (3) through a screw; the inner expansion sleeve (2) is in the shape of an outer cone; a circular hole is formed in the middle of the inner expansion sleeve (2) in a machining manner and deforms under the action of force; a groove is formed in the side wall of the inner expansion sleeve (2); the outer expansion sleeve (3) is in the shape of a cylinder as a whole and in the shape of an inner cone internally; the conical degree of the inner cone surface of the outer expansion sleeve (3) is the same as that of the outer cone surface of the inner expansion sleeve (2); a circular hole is formed on the minor diameter end of an inner cone hole of the outer expansion sleeve (3) in the machining manner; and the aperture of the circular hole is equal to the aperture of the inner expansion sleeve (2) and is matched with the diameter of a drawn steel bar. The mechanical clamping is realized by utilizing the inner and the outer expansion sleeves, so that the structure of the clamp is simple; and the clamp is automatically released by depending on the gravity of a steel bar after the steel bar is drawn, so that the manpower is saved.
Description
Technical field
The present invention relates to a kind of fixture, especially tapered expansion shell type steel bar cold draw machine clamp.
Background technology
Steel bar cold draw is the main machinery of industrial production intermediate materials, and major function is the bar that different-diameter is provided for factory, wire rod and various semi-finished product bar line material.The principle of its production process is simple, convenient operation, process velocity piece; Volume is little, easy for installation, automaticity is low; Can process technology content low, and cheap.Due to first-class feature, the use object of drawbench is more, and market is wider.
At present, the good fixture of the common neither one of drawbench on market, exists and wears silk difficulty, clamps effectiveness poor, and waste material is too many, the especially processing in early stage to fine steel rib of processing difficulties in early stage.At present drawbench fixture, mainly contains following two kinds: 1) Manual feeding clamp and unclamp; 2) realize Automatic-clamping and separate with linkage, but these two kinds of modes use relatively effort.
Summary of the invention
Based on above object, the present invention proposes a kind of tapered expansion shell type steel bar cold draw machine clamp, is made up of end cap 1, inner expension cap 2 and outer expansion set 3.Wherein inner expension cap 2 is arranged in outer expansion set 3 inside, and end cap 1 is arranged in the top of outer expansion set 3 and is connected by screw.
The present invention has the following advantages: (1) utilizes the mode of inside and outside taper expansion set to realize mechanical type and clamps, simple in structure; (2) after drawing, automatically loosen by reinforcing bar gravity, save artificial.
Accompanying drawing explanation
Fig. 1 is the assembling front view of tapered expansion shell type steel bar cold draw machine clamp of the present invention.
Fig. 2 is the inner expension cap front view of tapered expansion shell type steel bar cold draw machine clamp of the present invention.
Fig. 3 is the inner expension cap top view of tapered expansion shell type steel bar cold draw machine clamp of the present invention.
The specific embodiment
This equipments overall structure as shown in Figure 1, is made up of end cap 1, inner expension cap 2 and outer expansion set 3.Wherein inner expension cap 2 is arranged in outer expansion set 3 inside, and end cap 1 is arranged in the top of outer expansion set 3 and is connected by screw.
Main working process is first end cap 1 and drawbench draw-gear to be coupled together, the drawing reinforcing bar for the treatment of by wire-drawing die is penetrated from the circular hole of outer expansion set 3, approach axis is the direction of dehiscing of outer expansion set 3, and reinforcing bar continues across the circular hole of inner expension cap 2 until reinforcing bar head is pushed up on end cap 1; Then whole device is along with the direction motion of dehiscing of the outside expansion set 3 of drawbench draw-gear, under the effect of tractive force, inner expension cap 2 is along the inner conical surface counter motion of outer expansion set 3, because inner expension cap 2 sidewalls have a fluting, inner expension cap 2 produces distortion, thereby clamps reinforcing bar; After whole reinforcing bar pulls out from wire-drawing die, reinforcing bar after drawing can be because inertia be to the preshoot of drawing direction, and inner expension cap 2 moves to drawing direction along the inner conical surface of outer expansion set 3, thereby loosens reinforcing bar, reinforcing bar is deviate from from whole fixture due to Action of Gravity Field, completes steel bar cold draw process one time.
