Abstract

The utility model relates to a cold drawing machine which comprises a machine tool tailstock, a machine tool bed, a cold drawing trolley, a middle die holder, a machine tool head stock and a main hydraulic rod, wherein the machine tool tailstock is fixedly mounted at one end of the machine tool bed; the machine tool head stock is fixedly mounted at the other end of the machine tool bed; the middle die holder is fixedly mounted on the machine tool bed between a machine tool head box and a machine tool tail box; the cold drawing trolley is mounted on the machine tool bed between the machine tool tailstock and the middle die holder in a sliding manner; coaxial center holes are formed on the machine tool tailstock, the cold drawing trolley, the middle die holder and the machine tool head stock; the main hydraulic rod is fixedly mounted on the machine tool bed on the outer side of one end of the machine tool head stock and passes through the center hole of the machine tool head stock; the machine tool tailstock, the machine tool bed, the middle die holder and the machine tool head stock are all fixedly mounted on a base; and the base is formed by a bottom seat of an integral steel plate. The cold drawing machine has the advantages that the structure is simple, the design is reasonable, the smoothness of a machine tool foundation is effectively guaranteed, the coaxiality of processed work pieces is further guaranteed, a steel pipe is prevented from being bent and deformed during the processing, materials and manpower are saved, and the production efficiency and the production quality are remarkably improved.

Description

A kind of drawbench
Technical field
The utility model belongs to the steel pipe field, relates to steel pipe cold-drawn processing, especially a kind of drawbench.
Background technology
The production of seamless steel pipe need to begin the processing through steps such as check, pickling, phosphatization, saponification, cold-drawn, heat treatment, alignings from pipe; The drawbench pressure loading is big; And bed piece is longer; Each parts of lathe usually can take place because of pressure or skew in process, can't guarantee the axiality of processing work, and what existing drawbench pedestal adopted is the adjustable movable parallels of single separation; When needing to regulate lathe integral body glacing flatness, need adjust the corresponding parallels of each several part respectively.Now, steel pipe often bends in process, and through analyzing, the main cause that steel pipe occurs bending and deformation in Cold Drawing Process drawbench position component generation offset variation just causes.
Summary of the invention
The purpose of the utility model is to overcome the weak point of prior art, and the drawbench that a kind of design science is reasonable, simple in structure, stability is high is provided.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of drawbench; Comprise tailstock seat, lathe bed, cold-drawn dolly, middle die holder, head of a bed seat, master hydraulic bar; The tailstock seat is packed in lathe bed one end; Head of a bed seat is packed in the lathe bed other end, and middle die holder is packed on the lathe bed between headstock and the tailstock case, and the cold-drawn dolly is slidingly mounted on the lathe bed between tailstock seat and the middle die holder; Be shaped on coaxial centre bore on said tailstock seat, cold-drawn dolly, middle die holder and the head of a bed seat; Said master hydraulic bar is packed on the lathe bed outside head of a bed seat one end and passes the centre bore of head of a bed seat, and it is characterized in that: said tailstock seat, lathe bed, middle die holder, head of a bed seat all are packed on the pedestal, and this pedestal is by the formed pedestal of an integral plate base.
The advantage and the good effect of the utility model are:
1, this drawbench replaces with the integrally formed pedestal of steel plate base with the adjustable parallels of a plurality of separation; Guarantee the flatness on drawbench integral installation basis; Whole backing plate has effectively avoided the machine tool basic distortion to cause the influence to workpiece processing; And then the axiality of assurance processing work, significantly reduced the situation that tube bending is out of shape, promote production efficiency and quality.
2, this drawbench is installed on the whole pedestal, need not carry out independent adjustment to pedestal in the production, has saved the adjustment time, practices thrift manpower, promotes production efficiency.
3, the utility model simple in structure, reasonable in design, effectively guarantee the flatness of machine tool basic, and then guarantee the axiality of processing work, avoid tube bending distortion in the processing, economical with materials is practiced thrift manpower, significantly promotes production efficiency and quality.
Description of drawings
Fig. 1 is the utility model structural front view.
The specific embodiment
Below in conjunction with accompanying drawing and through specific embodiment the utility model is done further to detail, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.
A kind of drawbench; Comprise tailstock seat 7, lathe bed 4, cold-drawn dolly 6, middle die holder 5, head of a bed seat 3, master hydraulic bar 2, the tailstock seat is packed in lathe bed one end, and head of a bed seat is packed in the lathe bed other end; Middle die holder is packed on the lathe bed between headstock and the tailstock case; The cold-drawn dolly is slidingly mounted on the lathe bed between tailstock seat and the middle die holder, is shaped on coaxial centre bore on said tailstock seat, cold-drawn dolly, middle die holder and the head of a bed seat, workpiece and the coaxial installation of centre bore in the processing; Said master hydraulic bar is packed on the lathe bed outside head of a bed seat one end and passes the centre bore of head of a bed seat, and master hydraulic bar is coaxial with workpiece.
The innovative point of the utility model is:
Flatness for machine tool basic in guaranteeing to process; And then the axiality of assurance processing work; Said tailstock seat, lathe bed, middle die holder, head of a bed seat all are packed on the pedestal 1, and this pedestal is by the formed pedestal of an integral plate base, i.e. this pedestal employing adds steel plate and processes.
