The bending die structure of seamless pipe

Technical field

The utility model belongs to the punch process field of metal forming, relates to a kind of mould structure, relates in particular to a kind of bending die structure of seamless pipe.

Background technology

At present, in the punch process field of China's metal forming, the press-bending of seamless pipe is employed in the mode of processing on the bending machine usually and realizes.Adopt mass defects such as this technology tends to occur the workpiece attenuation, breaks, thickens, wrinkling, pipe fitting transverse shape distortion.Simultaneously, bending machine also has restriction to shape, size and minimum and the maximum caliber curved radius radius of processing tubing; Also need certain gripping section, stock utilization is lower, and operating efficiency is also low.

The utility model content

The purpose of the utility model is to provide a kind of bending die structure of simple in structure, easy to operate seamless garden pipe.Utilize this mould, can better guarantee product quality; Need not to keep long gripping section, improved stock utilization; Significantly enhance productivity, reduce artificial production cost.

The technical scheme of the utility model is: the bending die structure of seamless pipe comprises: upper plate, upper left module, guide post, middle upper module, upper right module, bottom right module, backing-out punch, T shape pressure pin, left lower module, lower shoe; It is characterized in that: middle upper module is fastened on the upper plate through screw and straight pin, and upper left module and upper right module are connected on the upper plate through special type screw, and guide post press fit on the negative; Bottom right module and left lower module are fastened on the lower shoe through screw and straight pin, and backing-out punch is connected on the lower shoe through special type screw, and lower shoe is provided with at least two pressure pin holes, and T shape pressure pin is packed in the pressure pin hole.

Upper left module, middle upper module, upper right module, left lower module, backing-out punch, bottom right module, the middle part all is designed with semicircle groove, and corresponding up and down.

It is 3 ° ~ 7 ° that the binder surface of upper left module and left lower module, upper right module and lower module is provided with the inclination angle.

Upper left module and left lower module, middle upper module and backing-out punch, upper right module and bottom right module, under closure state, being provided with the gap between the upper and lower mould is 0.1 ± 0.05mm.

The utility model can reach following beneficial effect:

Adopt this mould structure; Eliminated significantly the seamless circular tube wall in process because of the attenuation of stressed generation, thicken, break, defective such as wrinkling, distortion and depression, guaranteed the press-bending requirement of seamless pipe, guaranteed the quality of product effectively; Improved stock utilization; Improved production efficiency, reduced artificial production cost, for the innovation of seamless pipe press-bending processing technology provides useful experience.

Description of drawings

Accompanying drawing 1 is the cross-sectional schematic of transversary under the duty of bending die structure of the seamless pipe of the utility model.

Accompanying drawing 2 is the cross-sectional schematic of vertical structure under the duty of bending die structure of the seamless pipe of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further to describe.Shown in accompanying drawing, the bending die structure of seamless pipe mainly comprises: upper plate 1, upper left module 2, guide post 3, middle upper module 4, upper right module 5, bottom right module 6, backing-out punch 7, T shape pressure pin 8, left lower module 9, lower shoe 10; Middle upper module 4 is fastened on the upper plate 1 through screw and straight pin, and guide post 3 press fit on the negative 1, and upper left module 2 is connected on the upper plate 1 through special type screw with upper right module 5, and through guide post 3 guiding, through telescopic spring control stroke; Bottom right module 6 is fastened on the lower shoe 10 through screw and straight pin with left lower module 9, and lower shoe 10 is provided with at least two pressure pin holes, and T shape pressure pin 8 is packed in the pressure pin hole, and the boss that passes through on the T shape pressure pin 8 is spacing; Backing-out punch 7 is connected on the lower shoe 10 through special type screw, is promoted to rise by T shape pressure pin 8.

Upper left module 2, middle upper module 4, upper right module 5, left lower module 9, backing-out punch 7, bottom right module 6, the middle part all is designed with semicircle groove, and corresponding up and down, can be therein with piece-holder, and distortion is not radially appearring, keep the circularity of pipe.

Binder surface inclination alpha on upper left module 2 and left lower module 9, upper right module 5 and the bottom right module 6 is 3 ° ~ 7 °, is used to repair the resilience that produces after workpiece bends.

Upper left module 2 and left lower module 9, middle upper module 4 and backing-out punch 7, upper right module 5 and bottom right module 6, under closure state, design gaps δ is 0.1 ± 0.05mm between the upper and lower mould, makes workpiece to be out of shape vertically, does not produce defectives such as attenuation, fracture.

During work, backing-out punch 7 is adjusted to and bottom right module 6, left lower module 9 concordant states, workpiece is put into the semicircle groove of bottom right module 6, backing-out punch 7 and left lower module 9; The punch press top shoe is descending, upper left module 2 and upper right module 5 prepressing workpiece, and the punch press top shoe continues descending; Middle upper module 4 continues descending with backing-out punch 7 clamping workpiece; Spring compression upper left module 2 is up relatively with upper right module 5, realizes workpiece flexural deformation, finally reaches the product product requirement.

The utility model simple in structure, solid durable, cost of manufacture is lower, can alleviate working strength of workers, can satisfy requirement of mass production.Adopt this mould structure; Eliminated significantly the seamless rectangular tube wall in process because of the attenuation of stressed generation, thicken, break, defective such as wrinkling, distortion and depression, guaranteed the press-bending requirement of seamless pipe, guaranteed the quality of product effectively; Improve stock utilization; Improved production efficiency, reduced artificial production cost, for the innovation of seamless rectangular pipe press-bending processing technology provides useful experience.
