Abstract
The utility model discloses an auxiliary punch of an oil-pressure straightener, wherein a punch body is of a cuboid structure with a square bottom surface, the size of the bottom edge of the cuboid structure is not more than 500 mm, and two opposite side surfaces of the cuboid structure are both provided with mounting grooves, the mounting grooves on the two side surfaces are mutually symmetric, the mounting grooves on one side surface are bilaterally symmetric, the top surface of the cuboid structure is provided with a round caulking groove A, and the bottom of the round caulking groove A is further provided with a round caulking groove B along the central line. The auxiliary punch of the oil-pressure straightener has the advantages of simple structure, convenience for dismounting, and easiness for implementing in technology; as for straightening different kinds of products, the different auxiliary punches can be replaced for use, the replacing time is shortened, the pace of production is not influenced, and the influence on work efficiency caused by replacement of the punch is reduced; since reasonable size design is adopted in the prior art, the contact area of the straightening auxiliary punch and the workpiece is increased, the workpiece is prevented from being popped up due to pressing, and the security of the operation is improved.
Description
Technical field
The utility model relates to machinery and forges the casting technical field, especially relates to a kind of oil pressure straightener auxiliary punch.
Background technology
U.S. ArvinMeritor 3100 propons complex contours; Bigger through its distortion behind the tempering heat treatment; Deflection is the highest to account for more than 85% of sum, therefore its alignment is seemed particularly important, but adopt at present but unique deficiency be that the drift of the 160T oil pressure straightener that adopted is less than normal; Forging is under the effect of little stress surface in the alignment process; Can eject after pressure increases gradually, can not play positive role to the security of the workpiece that needs alignment on the work top, serious threat is to operator or near personnel's personal safety.
The utility model content
It is a kind of simple in structure that the purpose of the utility model is to provide, and easy accessibility is safe, has the oil pressure straightener auxiliary punch of higher applicability.
In order to achieve the above object; A kind of oil pressure straightener auxiliary punch of the utility model realizes through following technical scheme: a kind of oil pressure straightener auxiliary punch, described drift body are that the bottom surface is foursquare rectangular structure, and its base size is not more than 500mm; All have mounting groove on its two relative side; The mounting groove of described two sides is symmetrical, the mounting groove left-right symmetric on the same side, and its end face has circular caulking groove A; In the bottom of described circular caulking groove, also have circular caulking groove B along center line.The utility model is owing to all be provided with mounting groove on two of the drift body relative sides; And the mounting groove on the same side also becomes left-right symmetric, and 160T oil pressure straightener punch holder bottom is provided with T type mounting groove, and the pin of punch holder bottom surface embeds the circular trough of auxiliary punch end face; And employing T type screw; Its tail end passes the mounting groove of drift body, and screws with nut, and auxiliary punch is vertically fixed on the mount pad.In the bottom surface of auxiliary punch, can produce the shape groove consistent with the workpiece profile of alignment, further improve the security of alignment process operation.
As preferably, described drift body selects for use heat proof material to process, to satisfy the alignment requirement of hot alignment workpiece; As preferably, described drift body selects for use alloy material to process, to satisfy the alignment requirement of straighten while cold workpiece.
Compared with prior art; The beneficial effect of the utility model is: this apparatus structure is simple, easy accessibility, and realizes easily on the technology, when the alignment of product not of the same race is worked; Use different auxiliary punch instead; Shortened the replacing time, do not influenced productive temp, reduced and changed the influence of drift operating efficiency; Adopt rational size design for prior art, increased the contact area of alignment auxiliary punch and workpiece, avoided the workpiece pressurized to eject, improved the security of operation at present.
Description of drawings
The utility model will explain through example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 the utility model front view;
Fig. 2 the utility model side view;
This punch holder of Fig. 3 structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Shown in Fig. 1 and Fig. 2, a kind of oil pressure straightener auxiliary punch, a kind of oil pressure straightener auxiliary punch; Described drift body is that the bottom surface is foursquare rectangular structure, and its base size is not more than 500mm, all has mounting groove 1 on its two relative side; The mounting groove 1 of described two sides is symmetrical, mounting groove 1 left-right symmetric on the same side, and its end face has circular caulking groove A2; In the bottom of described circular caulking groove, also have circular caulking groove B3 along center line.As shown in figures 1 and 3, the utility model is owing to all be provided with mounting groove on two of the drift body relative sides, and the mounting groove on the same side also becomes left-right symmetric; And the pin 6 that punch holder 4 bottom surfaces of 160T oil pressure straightener are provided with T type mounting groove 5 and match with auxiliary punch top end face caulking groove; The round table-like pin 6 of punch holder bottom embeds the circular caulking groove A2 and the circular caulking groove A3 of auxiliary punch top end faces, and fixing auxiliary punch adopts T type screw more in the horizontal direction; Head is put into T shape mounting groove 5; Its tail end passes the drift body and is distributed in mounting groove 1 all around, and screws with nut, and auxiliary punch is vertically fixed on the mount pad.
As preferably, described drift body selects for use heat proof material to process, to satisfy the alignment requirement of hot alignment workpiece; As preferably, described drift body selects for use alloy material to process, to satisfy the alignment requirement of straighten while cold workpiece; In the bottom surface of auxiliary punch, can produce the shape groove consistent with the workpiece profile of alignment, further improve the security of alignment process operation.
This apparatus structure is simple, easy accessibility, and realizes easily on the technology, when the alignment of product not of the same race is worked, uses different auxiliary punch instead, has shortened the replacing time, does not influence productive temp, has reduced and has changed the influence of drift to operating efficiency; Adopt rational size design for prior art, increased the contact area of alignment auxiliary punch and workpiece, avoided the workpiece pressurized to eject, improved the security of operation at present.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
