Description

Pipe reducing die
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of pipe reducing die.
Background technology
Spinning is fixed on the mould of spinning machine by dull and stereotyped or hollow blank, while blank is with lathe main axis, with spinning roller or catch up with rod to stress on blank, makes it the plastic deformation producing local.Under the feed motion of spinning roller and the rotary motion acting in conjunction of blank, make the plastic deformation of local expand to all surfaces of blank step by step, and be close to mould, complete the rotary pressing processing of part.Spinning is a kind of special manufacturing process.The drawing of various shape rotary body, flange, reducing, the technique such as bulging and crimping can be completed by spin-on process.
In the prior art, adopt the mode of spinning to carry out necking forming to the pipe blank shown in Fig. 1, the advantage of this kind of processing mode is that equipment and mold is all fairly simple, and shortcoming is that productivity ratio is low, and labour intensity is large.This mode is not suitable for producing in enormous quantities, uses diel can very fast finishing the work, but the versatility of mould is poor, can only strike out a kind of model.
Utility model content
The purpose of this utility model is the necking die of the pipe blank providing the various model of a kind of energy punching press.
The utility model is achieved through the following technical solutions: pipe reducing die, comprise die socket, wherein, die socket is connected with driving mechanism, is fixed with die block below die socket, and die block lower end outer wall is provided with external screw thread, die block overcoat has the fixed cover removably connected, fixed cover coordinates the module slot in the middle part of die block to be connected with die block, and recessed module bottom surface offers punching press through hole, and the top of punching press through hole is provided with discharge ram; Be provided with convex mould base below die socket, be provided with the drift coordinating stamped groove in the middle part of convex mould base, convex mould base offers holddown groove in forcer position.
The beneficial effects of the utility model are: mention in background that existing pipe reducing die versatility is poor, cannot the pipe of punching press Multiple Type, the utility model devises the reducing die of the dismountable replacing of a kind of die block for this kind of situation, the die block of different model can be installed according to different situations, add the versatility of pipe reducing die, below by way of use procedure of the present utility model, the beneficial effects of the utility model are described, turn on fixed cover and fixed head, die is put into the mounting groove of fixed head, tighten fixed cover, die is fixed in mounting groove, pipe blank is placed on the holddown groove internal fixtion of convex mould base, by the inwall of elastic expansion sleeve at pipe blank, pipe is located.Start the drive unit of die socket, die socket moves down, and the die block of die socket coordinates the drift of convex mould base, and the mouth of pipe extruding being placed in the pipe blank of convex mould base reduced, after reducing completes, discharge ram releases shaping workpiece downwards.To sum up, the utility model not only completes the task of reducing efficiently, and adds the versatility of reducing die.
Further, the elastic expansion sleeve of fixing tube blank is provided with in holddown groove.Be only that holddown groove may fixing tube blank under huge stamping press completely, elastic expansion sleeve be set and between drift and holddown groove, pipe fixed further.
Further, fixed cover inwall is provided with screw thread, and the outer wall of fixed head is provided with screw thread, and fixed cover is threaded with fixed head.Fixed cover and fixed head removably connect, and adopt the mode of screw thread, have both ensured the stability after fixing, and also ensure that dismounting and change is quick.
Further, drift lower end is provided with thread segment, and drift is threaded with convex mould base.Drift is easily worn part, adopts the mode be threaded, and changes after damage.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the workpiece after the machine-shaping of the utility model structure pipe reducing die embodiment;
Fig. 2 is the structural representation of the utility model structure pipe reducing die embodiment
Reference numeral: discharge ram 1, die block 2, fixed head 3, fixed cover 4, elastic expansion sleeve 5, convex mould base 6, die socket 7, drift 8.
Detailed description of the invention
By reference to the accompanying drawings 1 with pipe reducing die described in Fig. 2, comprise die socket 7, wherein, die socket 7 is connected with driving mechanism, is fixed with die block 3 below die socket 7, and die block 3 lower end outer wall is provided with external screw thread, die block 3 overcoat has fixed cover 4, fixed cover 4 inwall is provided with screw thread, and the outer wall of fixed head 3 is provided with screw thread, and fixed cover 4 is threaded with fixed head 3.Fixed cover 4 coordinates the module slot in the middle part of die block 3 to be connected with die block 2, and die block 2 bottom surface offers punching press through hole, and the top of punching press through hole is provided with discharge ram 1; Be provided with convex mould base 6 below die socket 7, be provided with the drift 8 coordinating stamped groove in the middle part of convex mould base 6, drift 8 lower end is provided with thread segment, and drift 8 is threaded with convex mould base 6.Convex mould base 6 offers holddown groove in drift 8 position.The spring expanding sleeve of fixing tube blank is provided with in holddown groove.
Mention in background that existing pipe reducing die versatility is poor, cannot the pipe of punching press Multiple Type, the utility model devises the reducing die of the dismountable replacing of a kind of die block 2 for this kind of situation, the die block 2 of different model can be installed according to different situations, add the versatility of pipe reducing die, below by way of use procedure of the present utility model, the beneficial effects of the utility model are described, turn on fixed cover 4 and fixed head 3, die 2 is put into the mounting groove of fixed head 3, tighten fixed cover 4, die 2 is fixed in mounting groove, pipe blank is placed on the holddown groove internal fixtion of convex mould base 6, by the inwall of elastic expansion sleeve 5 at pipe blank, pipe is located.Start the drive unit of die socket 7, die socket 7 moves down, and the die block 2 of die socket 7 coordinates the drift 8 of convex mould base 6, and the mouth of pipe extruding being placed in the pipe blank of convex mould base 6 reduced, after reducing completes, discharge ram 1 releases shaping workpiece downwards.To sum up, the utility model not only completes the task of reducing efficiently, and adds the versatility of reducing die.The elastic expansion sleeve 5 of fixing tube blank is provided with in holddown groove.Be only that holddown groove may fixing tube blank under huge stamping press completely, elastic expansion sleeve 5 be set and between drift 8 and holddown groove, pipe fixed further.Fixed cover 4 inwall is provided with screw thread, and the outer wall of fixed head 3 is provided with screw thread, and fixed cover 4 is threaded with fixed head 3.Fixed cover 4 and fixed head 3 removably connect, and adopt the mode of screw thread, have both ensured the stability after fixing, and also ensure that dismounting and change is quick.Drift 8 lower end is provided with thread segment, and drift 8 is threaded with convex mould base 6.Drift 8 is easily worn parts, adopts the mode be threaded, and changes after damage.
