Abstract
The present invention provides a kind of drawbench forming tube clamping device, and structure includes support, lifting device, clamping device, guiding device and positioning pin；Support both ends are fixed on the chassis of c-type rack by bolt arrangement, and support middle position is through-hole, are set with lifting device in through-hole；Lifting device two sides are set with guiding device, and clamping device is set in the top of lifting device and guiding device；In device operational process, clamping device with lifting device effect, vertical ascent and decline are done along guiding device, when clamping device is raised to top clamped position, pin hole and positioning pin on clamping device are coordinated, for stablizing the position of clamping device, while can damage to avoid the brought pressure of tube-drawing to clamping device.The present invention avoids the problem of production tube due to caused by tubing elasticity is pulled from drawing die orifice in drawbench operational process, to improve the shaping rate of cold drawing steel tube by forming tube clamping device, the tail end of effectively fixed tubing.
Description
Technical field
The invention belongs to material molding machine technical fields, are related to a kind of cold-drawn unit of steel pipe, and in particular to Yi Zhongleng
Drawing machine forming tube clamping device.
Background technique
Tubing is profile common in people's life, and cold drawing steel tube production technology is the common technology of tube forming, existing
Drawbench, due to belonging to metal plastic deformation by drawing hollow forging, causes steel pipe to generate during the drawing process when carrying out drawing operation
Larger elastic force, so when the production tube being drawn is pulled from drawing die orifice, production tube meeting in drawing direction of drawing completion
There is a phenomenon where impacting forward, causing production tube pipe end to hit draw trolley makes production tube pipe end distort, it is this now want with
The reduction of finished product pipe outside diameter, deflection increase and the increase of finished product length of tube and become more serious, greatly reduce cold-drawn
The lumber recovery of steel pipe.
Summary of the invention
For above situation, the application's is designed to provide a kind of drawbench forming tube clamping device, can be effective
It avoids in drawing process, the finished product lumber recovery that tubing falls off, tilts and influence tubing.
To achieve the above object, the application, which adopts the technical scheme that, provides a kind of drawbench forming tube clamping dress
It sets, is set to the head end of drawing lathe bed, close to the side of drawing die holder and mold, positioned at the lower section of tubing tail portion；Forming tube
The structure of clamping device includes support, lifting device, clamping device, guiding device and positioning pin；Wherein support both ends pass through spiral shell
Stud structure is fixed on the chassis of c-type rack, and support middle position is through-hole, is set with lifting device in through-hole；Lifting device
Two sides are set with guiding device, and the clamping device is set in the top of lifting device and guiding device；In drawbench c-type rack
Side top is set with positioning pin, and clamping device, which is corresponding to it at position, is set with pin hole, in device operational process, clamping device with
The effect of lifting device, along guiding device do vertical ascent and decline, when clamping device is raised to top clamped position, folder
Pin hole and positioning pin on tight device are coordinated, and for stablizing the position of clamping device, while can be brought to avoid tube-drawing
Damage of the pressure to clamping device.
The operation of the drawbench forming tube clamping device is all made of hydraulic structure.
The drawbench forming tube clamping device is not to be constantly in clamped position, is set when tube-drawing length reaches
When the 90%-95% of measured length, start drawbench forming tube clamping device；Drawing is completed rear fixture and is opened simultaneously, by steel
Pipe is fallen from the drawing jaw of draw trolley.
The beneficial effects of the present invention are: by forming tube clamping device, the tail end of effectively fixed hollow forging avoids cold-drawn
Due to being deformed by drawing hollow forging in machine operational process, production tube is caused to pull from drawing die orifice, to improve the forming of cold drawing steel tube
Rate.

Specific embodiment
The application is illustrated by the following examples.As shown in Figure 1, the present invention provides a kind of drawbench forming tube
Clamping device is set to the first section of drawing lathe bed 1, close to the side of drawing die holder and mold 2, under tubing tail portion
Side；As shown in Figure 2,3, the structure of forming tube clamping device 3 includes support 4, lifting device 5, clamping device 6, guiding device 7
And positioning pin 8；Wherein 4 both ends of support are fixed on the chassis of c-type rack by bolt arrangement, and 4 middle position of support is through-hole,
Lifting device 5 is set in through-hole；5 two sides of lifting device are set with guiding device 7, and the clamping device 6 is set in lifting dress
Set the top of 5 Yu guiding device 7；Top is set with positioning pin 8 on the inside of drawbench c-type rack, and clamping device 6 is corresponding to it position
Place is set with pin hole 9, and in device operational process, clamping device 6 is done vertically with the effect of lifting device 5 along guiding device 7
Rise and fall, when clamping device 6 is raised to top clamped position, pin hole 9 and positioning pin 8 on clamping device 6 are coordinated, and are used for
Stablize the position of clamping device 6, while can damage to avoid the brought pressure of tube-drawing to clamping device.Drawbench forming
The operation of pipe clamping device 6 is all made of hydraulic structure.
Drawbench forming tube clamping device provided by the present invention is not to be constantly in clamped position, works as tube-drawing
When length reaches the 90%-95% of setting length, start drawbench forming tube clamping device, completes rear fixture to drawing and beat
It opens, steel pipe is fallen from the drawing jaw of draw trolley.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
It is familiar with those skilled in the art in the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of, should all contain
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
