Description
Technical field
The present invention relates to a kind of metal tube cold drawing equipment that is used for metallurgy industry, particularly relate to a kind of hydraulic cold drawn pipe machine that adopts hydraulic pressure pipe to be carried out tube reducing, hole enlargement or subtract wall as power source.
Background technology
In the metallurgical industry, the production of cold-drawn metal tube is the secondary operations of after hot rolling, extruding metal pipe material being carried out; Hydraulic cold drawn pipe machine is with metal pipe materials such as hot rolling seamless metal pipe or ERWs, the finished product tubing that the nothing cutting of producing by cold drawing, accurate wall thickness correspond to actual needs; Because the fluid pressure type cold drawing tube machine is compared advantage such as have the precision height, pull out force is big, energy consumption is little, production efficiency is high and device structure is simple with the mechanical transmission-type cold drawing tube machine, and more and more is used widely; For example, Chinese invention patent ZL200620076519.9 discloses a kind of hydraulic cold drawn pipe machine, its clamp dolly clamping of passing through to be driven by master cylinder is by the drawing pipe, from the master cylinder seat drawing of drawing-die seat to the installation master cylinder, thereby make by the crystal grain of drawing pipe the mobile finished product tubing that obtains takes place longitudinally longitudinally; When this class drawbench carries out the tube drawing operation, because the pulling force effect of clamp dolly, make that the lathe bed between lathe bed, drawing-die seat and the core bar seat between master cylinder seat and the drawing-die seat is compressed distortion; Big more by the caliber of drawing pipe, required pulling capacity is also big more, it is big that this compression also becomes with being directly proportional, people are for overcoming lathe bed compression, usually take to fixedly connected with the handpan of concrete casting by numerous foundation bolts at master cylinder seat, drawing-die seat, core bar seat and the lathe bed between them; Like this along with big more by the caliber of drawing pipe, required foundation bolt is also many more, to the requirement of ground and also high more to the compression strength and the rigidity requirement of lathe bed, makes the equipment cost of drawbench, installation cost improve greatly, complex structure, install loaded down with trivial detailsly, bring very big inconvenience to the user.
Summary of the invention
The objective of the invention is to: fixedly connected with the handpan of concrete casting by foundation bolt at present hydraulic cold drawn pipe machine, the high practical problem of the compression strength of ground, foundation bolt and lathe bed and rigidity requirement in the work, provide a kind of can be with simple in structure, can overcome the compression of lathe bed effectively, and the hydraulic cold drawn pipe machine lower, with low cost, easy for installation to the requirement of ground.
The object of the present invention is achieved like this: a kind of hydraulic cold drawn pipe machine comprises:
Be used to install the master cylinder seat of master cylinder;
Inside is provided with the drawing-die seat of mould;
The clamp dolly that between master cylinder seat and drawing-die seat and by master cylinder, drives;
Be used to penetrate the core bar seat of location core bar;
Described master cylinder seat, drawing-die seat and core bar seat are fixedly connected on the end of first lathe bed, second lathe bed;
Described master cylinder seat, first lathe bed, drawing-die seat, second lathe bed, core bar seat arrange vertically successively, the clamp dolly between master cylinder seat, drawing-die seat along the first lathe bed axially-movable;
Master cylinder seat, core bar seat and first lathe bed, second lathe bed below are equipped with and stop its lateral displacement restraint device, the spill locating slot of lateral displacement restraint device is made of base plate and both sides shelves, or the L shaped parts that formed by base plate and side shelves constitute after the longitudinal axis symmetric arrangement, and described lateral displacement restraint device is fixedlyed connected with ground.
In the present invention: the spill locating slot that the bottom of master cylinder seat, core bar seat and first lathe bed, second lathe bed places described base plate and side shelves to surround respectively.
In the present invention: described side shelves are the side plate that is located at the base plate side.
In the present invention: described side shelves be the base plate side two straight pins of being furnished with the rolling sleeve are set at least.
In the present invention: described first lathe bed top height L1 overhead is greater than by drawing pipe axis height L2 overhead.
In the present invention: described drawing-die seat places the lateral displacement restraint device, or directly fixedlys connected with ground.
In the present invention: described drawing-die seat is fixedlyed connected with ground by the lateral displacement restraint device.
The invention has the advantages that: because this hydraulic cold drawn pipe machine is provided with the lateral displacement restraint device, during trombone slide, first, second lathe bed mainly is subjected to compression stress vertically, and the power that laterally is subjected to is very little, in other words, axial compression mainly takes place in first, second lathe bed, and transversely deforming is very little; Because master cylinder seat and core bar seat can be free to slide in the spill locating slot, thereby overcome the axial compression of first, second lathe bed, again because the transversely deforming amount is very little, thereby only need the spill locating slot to be fixedlyed connected with ground by several foundation bolts, just can overcome first, second lathe bed laterally moves, less demanding, therefore with low cost to ground installed also very convenient.
As a kind of improvement of the present invention, the part of described first, second lathe bed is contained in the groove that is surrounded by the base plate of described spill locating slot and both sides shelves, and is with this groove and is slidingly matched, and described spill locating slot is fixedlyed connected with ground; Perhaps the part of described first, second lathe bed is contained between the straight pin of being furnished with the rolling sleeve of described positioned opposite, and is to roll with this straight pin and cooperates, and described base plate is fixedlyed connected with ground.After adopting such structure, not only can more effectively stop this hydraulic cold drawn pipe machine traversing, and can save the lathe bed material, also more favourable to the stability of whole equipment.
As another kind of improvement the of the present invention, described first lathe bed top height L1 overhead is greater than by drawing pipe axis height L2 overhead.After adopting such structure, the compression that on the one hand can alleviate lathe bed also can make the pipe of the bigger caliber of this drawbench drawing on the other hand.
