Abstract
The utility model relates to the technical field of cold drawing die, especially a kind of production seamless steel pipe cold drawing die, there is cold-drawn die sleeve and cold-drawn core rod, rectangle left chamber and the right chamber of coupled logical dovetail shaped is offered in described cold-drawn die sleeve, described cold-drawn core rod enters from rectangle left chamber and blocks in the right chamber of dovetail shaped, offer isosceles trapezoid left chamber and the right chamber of coupled logical rectangle in cold-drawn core rod, cold-drawn core rod is fixed in cold-drawn die sleeve by several fastening bolts; The width dimensions of described rectangle left chamber is more than or equal to the diameter dimension of cold-drawn core rod, and the left side width size of the right chamber of described dovetail shaped is less than the diameter dimension of cold-drawn core rod.This production seamless steel pipe cold drawing die, can produce the seamless steel pipe of different-diameter size, versatility is stronger.
Description
Technical field
The utility model relates to the technical field of cold drawing die, especially a kind of production seamless steel pipe cold drawing die.
Background technology
Seamless steel pipe has hollow section, and a large amount of pipeline being used as conveying fluid, as transfer oil, natural gas, coal gas, water and some solid material etc.Seamless steel pipe compared with the solid steel such as round steel, under identical bending resistance torsional strength, the lighter in weight of seamless steel pipe; Meanwhile, seamless steel pipe is also widely used in manufacturing structure part and machine components, and as the steel scaffold etc. in oil drill rocker, truck drive shaft, bicycle rack and construction, stock utilization is high, and manufacturing process is simple and easy, and machining period reduces.
Just because of the particularity of seamless steel pipe purposes, therefore, need to use various production equipment in the production process of seamless steel pipe, cold drawing die is exactly produce one very important in seamless steel pipe equipment.
But, existing most of cold drawing die comes with some shortcomings part in structural design, and cold-drawn die sleeve and the cold-drawn core rod of most cold drawing die are one-body molded, and the diameter dimension of the seamless steel pipe causing cold drawing die to be produced immobilizes, versatility is poor, and economic utilization rate is not high.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the prior art Problems existing in above-mentioned background technology, and provide a kind of and produce seamless steel pipe cold drawing die, can produce the seamless steel pipe of different-diameter size, versatility is stronger.
The utility model solves the technical scheme that its technical problem adopts: a kind ofly produce seamless steel pipe cold drawing die, there is cold-drawn die sleeve and cold-drawn core rod, rectangle left chamber and the right chamber of coupled logical dovetail shaped is offered in described cold-drawn die sleeve, described cold-drawn core rod enters from rectangle left chamber and blocks in the right chamber of dovetail shaped, offer isosceles trapezoid left chamber and the right chamber of coupled logical rectangle in cold-drawn core rod, cold-drawn core rod is fixed in cold-drawn die sleeve by several fastening bolts; The width dimensions of described rectangle left chamber is more than or equal to the diameter dimension of cold-drawn core rod, and the left side width size of the right chamber of described dovetail shaped is less than the diameter dimension of cold-drawn core rod.
Further specifically, the depth dimensions in the left chamber of described rectangle is greater than the height dimension of cold-drawn core rod.
Further specifically, the width dimensions of the right chamber of described rectangle is less than dovetail shaped right chamber left side width size.
The beneficial effects of the utility model are: production seamless steel pipe cold drawing die of the present utility model, by cold-drawn die sleeve and cold-drawn core rod are designed to split type structure, the cold-drawn core rod of different size is selected to be embedded in cold-drawn die sleeve according to the seamless steel pipe of different-diameter size, and with trip bolt, cold-drawn core rod is fixed on cold-drawn die sleeve inside, make this cold-drawn grinding tool can produce the seamless steel pipe of different-diameter size, versatility is comparatively strong, and economic utilization rate is higher.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Label in accompanying drawing is: 1, cold-drawn die sleeve, 1-1, rectangle left chamber, the right chamber of 1-2, dovetail shaped, 2, cold-drawn core rod, and 2-1, isosceles trapezoid left chamber, the right chamber of 2-2, rectangle, 3, fastening bolt.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, produce seamless steel pipe cold drawing die, there is cold-drawn die sleeve 1 and cold-drawn core rod 2, rectangle left chamber 1-1 and the right chamber 1-2 of coupled logical dovetail shaped is offered in described cold-drawn die sleeve 1, described cold-drawn core rod 2 enters from rectangle left chamber 1-1 and blocks in the right chamber 1-2 of dovetail shaped, offer isosceles trapezoid left chamber 2-1 and the right chamber 2-2 of coupled logical rectangle in cold-drawn core rod 2, cold-drawn core rod 2 is fixed in cold-drawn die sleeve 1 by several fastening bolts 3; The width dimensions of described rectangle left chamber 1-1 is more than or equal to the diameter dimension of cold-drawn core rod 2, and the left side width size of the right chamber 1-2 of described dovetail shaped is less than the diameter dimension of cold-drawn core rod 2.Cold-drawn die sleeve 1 and cold-drawn core rod 2 are designed to split type structure, select the cold-drawn core rod 2 of different size to be embedded in cold-drawn die sleeve 1, and cold-drawn core rod 2 is fixed on the inside of cold-drawn die sleeve 1 with trip bolt 3 according to the seamless steel pipe of different-diameter size.
Wherein, the depth dimensions of described rectangle left chamber 1-1 is greater than the height dimension of cold-drawn core rod 2.The width dimensions of described rectangle right chamber 2-2 is less than dovetail shaped right chamber 1-2 left side width size.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
