Abstract
The utility model provides a kind of combined bracket slide, to solve the pipe feeding difficulty that existing bracket slide extensively exists, the defect of plug frangibility because not having centering machine, this combined bracket slide comprises pipe bracket and mandrel bracket two part, wherein the structure of pipe bracket is: the two-sided rack and top roll wheel carrier affixed, left and right tooth bar and lower roll wheel carrier affixed, cylinder promotes upper roll wheel by the two-sided rack top roll wheel carrier and moves, drive left and right gear to rotate simultaneously, make the oppositely movement of left and right tooth bar, drive lower roll wheel moves, hold pipe or plug, the structure of mandrel bracket is similar to pipe bracket, difference is that the running roller of pipe bracket is perpendicular to rolling centerline and rotates, the running roller of mandrel bracket is parallel to rolling centerline to rotate.Combined bracket slide has compact conformation, self-centering is good, and material loading is easily reliable, and labour intensity is low, production efficiency is high, the feature of good product quality, can be widely used on cold pilger mill.
Description
Technical field
The utility model relates to the combined bracket slide on a kind of cold pilger mill.
Background technology
Bracket slide is used on the relatively large cold pilger mill of end material loading, between mandrel chuck and feeding trolley.Bracket slide has two pipe bracket slides, two core bar bracket slides are alternately arranged on lathe bed.As shown in Figure 1, four bracket slide carriage structures are identical, and be made up of slide seat body 3, guide pin bushing 2 respectively, guide pin bushing 2 is replaceable according to the caliber size of pipe 1.Owing to needing the plug 4 of rolling longer and heavier, seriously sagging, during material loading, pipe 1 end face encounters the inclined-plane of cover 2, difficulty is sent under the compressing of plug 4, direct labor often uses crow bar to lever up plug 4 and pipe 1, sometimes use driving to assist to hold up pipe 1 and plug 4, pipe could be passed through bracket one by one, not only time-consuming but also require great effort.Because plug 4 does not have centering machine, during rolling, plug jerk value is large, and top easily fractures, and not only affects output but also affect quality, also add production cost.Curve guide impeller must be carried out, to meet need of production to above-mentioned bracket slide.
Summary of the invention
The utility model is the bracket slide that will provide a kind of improvement---combined bracket slide, to solve the many defects existed in prior art.
Combined bracket slide of the present utility model can adopt following technical scheme to implement: it comprises pipe bracket and mandrel bracket two part, wherein pipe bracket comprises cylinder, the two-sided rack, top roll wheel carrier, lower roll wheel carrier, left tooth bar, right tooth bar, left and right gear, upper roll wheel and lower roll wheel, wherein cylinder is connected with the two-sided rack one end, the two-sided rack other end is connected with top roll wheel carrier, upper roll wheel is contained on top roll wheel carrier, lower roll wheel is contained on lower roll wheel carrier, top roll wheel carrier is connected respectively at left tooth bar and right tooth bar with the two ends of lower roll wheel carrier, left, right gear is respectively at the two-sided rack and a left side, right tooth bar connects, mandrel bracket is similar to pipe carrier structure, and difference is that the running roller of pipe bracket is perpendicular to rolling centerline and rotates, and the running roller of mandrel bracket is parallel to rolling centerline to rotate.
The combined bracket slide designed according to technique scheme compared with prior art its major advantage is: compact conformation, self-centering is good, during material loading, pipe and plug are positioned on rolling centerline automatically, not friction between pipe and plug, the running roller of pipe all the time on pipe bracket moves ahead under holding in rolling friction.During rolling, plug holds lower rotation at the running roller of mandrel bracket, does not produce sagging, jitter phenomenon, and pipe and the change of plug external diameter are also without the need to changing running roller.

Detailed description of the invention
Below in conjunction with drawings and Examples, combined bracket slide of the present utility model is further described.
As Fig. 2, shown in Fig. 3, combined bracket slide comprises pipe bracket and mandrel bracket two part, wherein: pipe bracket comprises cylinder 21, the two-sided rack 22, top roll wheel carrier 26, lower roll wheel carrier 29, left tooth bar 25, right tooth bar 24, left and right gear 23, upper roll wheel 27 and lower roll wheel 28, wherein cylinder 21 is connected with the two-sided rack 22 one end, the two-sided rack other end is connected with top roll wheel carrier 26, upper roll wheel 27 is contained on top roll wheel carrier 26, lower roll wheel 28 is contained on lower roll wheel carrier 29, top roll wheel carrier is connected with left tooth bar 25 and right tooth bar 24 respectively with the two ends of lower roll wheel carrier, left and right gear 23 respectively with the two-sided rack and a left side, right tooth bar engagement, mandrel bracket is similar to pipe carrier structure, and difference is that the running roller of pipe bracket is perpendicular to rolling centerline N and rotates, and the running roller of mandrel bracket is parallel to rolling centerline N to rotate.
According to said structure form make combined bracket slide work time as shown in Figure 4: two pipe bracket A1 are identical with A2(structure) and two mandrel bracket B1 identical with B2(structure) be alternately arranged on plug 4.During material loading, mandrel bracket B1, mandrel bracket B2 close, and hold plug, and pipe bracket A1, pipe bracket A2 open; When blank end is by pipe bracket A1, pipe bracket A1 closes, and hold pipe, mandrel bracket B1 opens; When blank end is by pipe bracket A2, pipe bracket A2 closes, and hold pipe, mandrel bracket B2 opens; When pipe afterbody is by mandrel bracket B1, mandrel bracket B1 closes, and holds plug, and pipe bracket A1 opens; When pipe afterbody is by mandrel bracket B2, mandrel bracket B2 closes, and pipe bracket A2 opens.Such pipe just have passed bracket slide easily.
