Description

A kind of bearing roller formula structure bending machine die

Technical field

The utility model relates to a kind of bending machine die, especially relates to a kind of bearing roller formula structure bending machine die.

Background technology

In processing ironware product, often running into needs the ironware product of processing that the bending structure is arranged, and this handles it with regard to the corresponding bending machine die of needs.We have following several by the bending machine die of existing processing ironware product:

Chinese patent has provided a kind of " sheet metal bender " for No. 92238094.5, and this machine is at the hinged bend bar in template side, and during bent plate, bend bar is that rotate and the brake forming of pushing sheet material at the center with the hinge.In the bending machining process, bend bar does not have relative sliding friction with sheet material, can avoid sliding injury plate surface in process.With the demanding casing deckle board of presentation quality, moulding perfection and plate surface not damageds such as this machined refrigerator doors.

And for example Chinese patent has provided a kind of " plate, swan neck system " for No. 200420000882.3, and this device comprises positioning module and major and minor fixture block, and positioning module has a folder face and a forming surface, and the main folder piece is by a fixture block seat, buffing pad and the phase composition of cylinder pressure seat; The fixture block seat, two end plates outer panel face is provided with a spring base, and spring base one end spiral shell is established a screw.The spring base other end recess of having sagged, spring is fixed in two end plates outer panel face; Buffing pad is by a track base and holding plate phase composition: each end face of track base both ends of the surface respectively pierces screw, uses screw one block is locked in screwhole position, with track base and hold a seat locking one, forms guide rail with the predetermined quantity screw in both sides, track base bottom surface; The cylinder pressure seat is by cylinder pressure, connection rod set and the phase composition of guide-track groove seat: the piston club head of cylinder pressure is inserted an intrinsic connection rod set, and connection rod set upper end seat surface is provided with up in regular turn that number axis holds and the guide-track groove seat.Can accurately plate, tubing be bent into predefined curved angle with this machine, and obtain the bending part that surface smoothing does not have impression.

Through the ironware product of above-mentioned several bending machine die processing, bending part more or less all has certain polishing scratch after the moulding, concerning the ironware product of the high environment-friendly type of appearance requirement, influences the quality and the qualification rate of ironware product; And along with the variation of the market demand, some newly-designed ironware products not only require the perfection of material bending moulding, also require to stamp out on the plate face concavo-convex shape simultaneously, and above-mentioned sheet metal bending make-up machine can only be limited to the ironware product of surperficial no concave-convex shape.

The utility model content

Main purpose of the present utility model is to provide a kind of novel bending machine die, can realize that the bending structure position of ironware product does not have polishing scratch after the moulding, to reach the ironware product standard of the high environment-friendly type of appearance requirement; And ironware product that can the irregular shape of finished surface.

For achieving the above object, the utility model provides a kind of bearing roller formula structure bending machine die, comprise upper bolster and die shoe, upper and lower die holder is carved mutually to close with guide pillar by guide pin bushing and is assembled together, backboard, spring and patrix forming terrace die are installed on the bottom surface of upper bolster, lower bolster, holding pad, inner guiding post, binder spring, contour screw and roller bearing are installed on the die shoe, and described roller bearing is fixed on the die shoe by the ball fixed block.

More preferably, described roller bearing be by last contour forming slide block the compression spring process in, a reaction force that is given by spring impels its rotation.

Compared with prior art, when the utility model adopts upper bolster descending, the ironware product of required processing is carried out the mode of bending by roller bearing, avoided in the bending process at the surface of ironware product generation polishing scratch, and owing to the horizontal range between the contour forming slide block on the horizontal range relative two between the two roller bearing inboards is processed the thickness of ironware product approximately greater than need, so there is the ironware product of concaveconvex shape also can carry out Bending Processing for the surface.

The specific embodiment

For describing technology contents of the present utility model, structural feature in detail, illustrated in detail below in conjunction with embodiment and conjunction with figs..

See also Fig. 1 and Fig. 2, the same for bearing roller formula structure bending machine die of the present utility model with common U type bender, constitute by upper bolster 11 and die shoe 1, carve mutually to close with guide pillar 22 by guide pin bushing 21 between the two and be assembled together.Be equipped with on the bottom surface of upper bolster 11: go up backboard 12, patrix forming terrace die 13,

spring

16 and 17 and patrix forming terrace die 14 and 15.Lower bolster 2, holding pad 3, inner guiding post 6, binder spring 7, contour screw 8 and ball

fixed block

5 and 9 are installed on the die shoe 1; Comprise a roller bearing 4 and 10 in the described ball

fixed block

5 and 9 respectively, and the horizontal range between roller bearing 4 and 10 inboards goes up horizontal range between the contour forming

slide block

14 and 15 outsides relatively approximately greater than the thickness of need processing ironware product 30, when upper and lower mould is fitted, last contour forming

slide block

14 and 15 and patrix forming terrace die 13 all between two roller bearings.Thereby contour screw 8 passes corresponding counterbore on the die shoe 1 and is screwed in the screw on holding pad 3 bottom surfaces holding pad 3 outstanding positions of holding in the palm certain distance on distance die shoe 1, and defining the direction that its pressurized falls, inner guiding post 6 is used to control the location of the horizontal direction of holding pad.

Operation principle of the present utility model is as follows:

When producing, hydraulic press driving upper bolster 11 drive patrix forming terrace dies 13 and last contour forming

slide block

14 and 15 are descending, and when the part of the upper die contacted with holding pad 3, ironware product 30 was compressed gradually.Patrix continues descending, after the roller bearing 10 of the roller bearing 4 of last contour forming slide block 14 and counterdie, last contour forming slide block 15 and counterdie is in contact with one another by ironware product 30, last contour forming slide block 14 is gone up contour forming slide block 14 1 reaction forces by spring 16 and is impelled roller bearing 4 to clockwise rotate in the process of compression spring 16; Contour forming slide block 15 is gone up contour forming slide block 15 1 reaction forces by spring 17 and is impelled roller bearing 10 to rotate counterclockwise in the process of compression spring 17 on the same principle, fits fully up to upper and lower mould, finally finishes the moulding of ironware product.During the hydraulic press backhaul, holding pad 3 is got back to the home position under the effect of binder spring, and patrix forming slide 14 and patrix forming slide 17 are got back to the home position respectively under the effect of spring 16 and spring 17 simultaneously.When hydraulic press drive patrix runs to highest order, can take out the ironware product of machine-shaping from counterdie.

The above, above-mentioned embodiment of the present utility model all can only be thought can not limit the utility model to explanation of the present utility model, claims have been pointed out scope of the present utility model, and scope of the present utility model is not pointed out in above-mentioned explanation, therefore, in implication suitable and any change in the scope, all should think to be included in the scope of claims with claims of the present utility model.
