Abstract

The utility model relates to a die, particularly to a die for pressing a convex mark or a concave mark on the surface of a circular pipe along the peripheral direction of the pipe. The die comprises a cylindrical female die and a cylindrical male die. A groove is arranged on the peripheral surface of the female die, a convex object is arranged on the peripheral surface of the male die, and the shapes of the groove and the convex object are matched. The use method of the die comprises allowing the female die and the male die to face to face with a certain distance, sheathing a circular pipe to be pressed on one die and enabling the surface of the circular pipe to closely attach to the groove or convex object on the surface of the die, rotating the die, and gradually moving the other die and approaching to the circular pipe to press a convex mark or a concave mark on the surface of the circular pipe in the position corresponding to the groove or convex object. The pressing die provided by the utility model has very simple structure and convenient use, and is matched with many equipment in the prior art, so as to reduce equipment investment cost.

Description

The impression mould

Technical field

The utility model relates to a kind of mould, is exactly the mould that is used for circumferentially suppressing along pipe on the pipe surface convex epirelief or indenture specifically.

Background technology

Need because of using, many metal circular tubes surface needs compacting along the convex epirelief or the indenture that circumferentially connect, the soft or hard pipe junction of the oil that on hydraulic pressure or pneumatic circuit, uses, feed channel for example, usually need just metal tube surface extrude convex epirelief at hard tube, go up difficult drop-off afterwards to it to guarantee tube socket.Existing on metal tube the method and apparatus of the recessed/convex epirelief of compacting more, but complex structure mostly, operating process is loaded down with trivial details, employed mould is also different, uses inconvenience.

Summary of the invention

The purpose of this utility model just provides a kind of impression mould simple in structure, utilizes this mould recessed/convex epirelief of compacting on metal circular tube easily.

The scheme that adopts is exactly a kind of impression mould, comprises cylindrical former and formpiston, and the former side face is provided with groove, and the formpiston side face is provided with convex epirelief, the form fit of groove and convex epirelief.

During use, former is relative with convex epirelief with groove on the formpiston, both separate certain distance, the pipe that will need then to suppress is enclosed within on the mould, and make the pipe inner surface press close to the apparent surface of two moulds, utilize any technique known that one of them mould is rotated around the axle core then, utilize simultaneously elevating mechanism with two moulds gradually near and be close together, pipe and two cylindrical dies all can rotate around the axle core separately so, and the position correspondence just has been forced out recessed or convex epirelief on the surface of convex epirelief, groove on the pipe.Such mould structure is extremely simple, and is easy to use; And can both mate use with many equipment of prior art, not only improve working (machining) efficiency but also reduced processing cost.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the left view of Fig. 1.

The specific embodiment

A kind of impression mould as shown in Figure 1, comprise formpiston 10 and former 20, former 20 is cylindrical, its side face is provided with groove 21, formpiston 10 also is cylindrical, its side face is provided with convex epirelief 11, the cross sectional shape of groove 21 equals or is slightly larger than the cross section of convex epirelief 11, it preferably is exactly the wall thickness that the size difference of two sections just equals pipe 30 to be processed, as shown in Figure 1, with formpiston 10 fixed-site, the pipe 30 that will need then to suppress is enclosed within on the formpiston 10, and makes the upper inside surface of pipe 30 press close to the convex epirelief 11 of the outer surface of upper of formpiston 10, utilizes prior art that formpiston 10 is rotated around the axle core, utilize the position of the elevating mechanism of any known configurations convex epirelief 11 that 21 position alignment of the groove on the former 20 are above-mentioned then, while former 20 also is arranged to can be along the state of axle core rotation, and mobile gradually then former 20 is near pipes 30, and formpiston 10 and former 20 relative side faces clamp pipes 30 so, around axle core rotation separately, pipe 30 outer peripheral faces just are forced out the vestige of evagination to the three under the drive that formpiston 10 rotates.Such mould structure is simple, uses also easily and can both mate use with many equipment of prior art, and not only working (machining) efficiency is high but also save equipment investment cost, makes processing cost reduce.

Formpiston 10, former 20 are just comparatively speaking, what common surface exactly was provided with groove 21 is former 20, the surface is provided with the formpiston that is of convex epirelief 11, illustrated situation is at pipe 30 Surface Machining convex epireliefs, as need at pipe 30 Surface Machining indentures, only need pipe 30 to be enclosed within former 20 peripheries and get final product, its processing method is identical with step.Then be not strict with as for the moving direction that adds the mould in man-hour, can decide according to the equipment situation, but fixing for the ease of pipe 30 usually, pipe 30 is enclosed within on the fixing mould in center usually, and move another mould near or away from the fixing mould of pipe 30 and center; As shown in Figure 1 be exactly that pipe 30 is enclosed within on the formpiston 10, elevating mechanism drives former 20 and moves, the elevating mechanism that its advantage comes to this only needs mobile former 20, and need not to move other parts, the structure of elevating mechanism can greatly be simplified like this, and energy consumption reduces, and also is convenient to operation simultaneously.

Columned former 20 and formpiston 10 rotate with pipe 30, have greatly reduced the suffered frictional force of mould and pipe 30, have reduced the wearing and tearing of mould; Simultaneously guarantee symmetrical configuration again, guarantee machining accuracy.

Further, described former 20 and formpiston 10 be the pipe shape preferably, and indenture 21, convex epirelief 11 preferably connects along the same cross section of the outer peripheral face of body and be provided with, and we can say that also indenture 21 on the mould side face, convex epirelief 11 are in the form of a ring and perpendicular to the axle core of mould.As shown in Figure 1, 2, so not only can utilize finished product round steel or steel pipe to process easily, and the groove 21 of ring-type setting and convex epirelief 11 can further guarantee the shape symmetry of recessed/convex epirelief of being suppressed, improve pressing result, and mould cylindrical or title hollow shaft shape is easier to also connect and be fixed on the process equipment.For example offer keyway along shaft core direction, can be rotationally connected with rotating shaft at the axle inwall.And the former 20 of hollow shaft shape and formpiston 10 can also process easily with round steel, and be so not only easy to process, and the weight that can save mould, not only saves die manufacturing cost but also reduce the energy consumption of process equipment.
