Description

A kind of column forging fixture

Technical field

The utility model relates to a kind of fixture, and in particular, it relates to a kind of column forging fixture.

Background technology

Forging is that metal is applied in pressure, moulds the shape of requirement or the object of suitable compressive force by plastic deformation.This strength realizes typically by use iron hammer or pressure.Forging process has built exquisite grain pattern, and improves the physical attribute of metal.

In actual production process, often need the forging producing some columns, this forging often build is very large, each probably have hundreds of jin about, a very troublesome thing when needs move these column forging, need large-scale weight-lifting equipment to move, when but large lifting equipment needs to lift this kind of column forging, this kind of column of fixture gripping forging is used to be more difficult, in prior art, fixture is generally provided with two clamping bars be hinged, and the sidewall of column forging is rounded, clamping bar is less because of the limited friction force that causes of area of contact in gripping column forging process, be very easy to landing like this, inconvenient gripping and the success ratio of gripping is lower like this, need repeated multiple times could being clamped, and if the phenomenon that drops in moving process can cause dangerous generation, therefore need to propose a kind of scheme and solve this problem.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of and facilitates gripping and can stablize the column forging fixture of gripping column forging.

For achieving the above object, the utility model provides following technical scheme: a kind of column forging fixture, comprise holding part, convergence part and clasp, described holding part comprises two clamping bars be hinged, the end of each clamping bar is all fixedly connected with in half-elliptic grip block, two mutual socket connections of grip block, described convergence part is two chains, one end of described two chains is connected with two clamping bars respectively, the other end is all connected with clasp, described grip block comprises the contact surface for conflicting with column forging, fit in the surface of described contact surface and column forging, described contact surface is also bonded with rubber pad.

As preferably, described two clamping bars are hinged by attaching parts.

As preferably, described two clamping bars arrange at 2/3 place near grip block one end and offer through hole, and described attaching parts is fed through through hole and is limited on attaching parts by two clamping bars.

The utility model has following advantage compared to existing technology: by by hinged for two clamping bars, the bare terminal of clamping bar is that plate ellipticalness arranges formation grip block, grip block is for increasing the area of contact with column forging, all chain is connected with at the other end of each clamping bar, the other end of two chains all snaps onto on clasp, clasp is for connecting weight-lifting equipment, like this when carrying out clamping displacement to column forging, only need the side-walls two pieces of grip blocks being arranged on column forging, then when weight-lifting equipment pulls clasp to sling, column forging clamps to establishing by two pieces of grip blocks automatically, and rubber pad bonding on the contact surface of grip block can increase the area of contact with column forging, this makes it possible to having been clamped by column forging tightly, arrange like this structure simple and can clamp firm, can not be dropped phenomenon in handling process.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of column forging of the utility model fixture.

In figure: 1, clasp; 2, convergence part; 3, holding part; 4, attaching parts; 5, bare terminal; 6, grip block; 7, contact surface.

Detailed description of the invention

Be described further with reference to the embodiment of Fig. 1 to a kind of column forging of the utility model fixture.

As shown in Figure 1, column forging fixture comprises clasp 1, convergence part 2 and holding part 3, holding part 3 is made up of two clamping bars, two clamping bars form by two microscler iron bar one end are bending, this bending one end is bare terminal 5, bare terminal 5 bends in semiellipse type, two clamping bars just can form ellipse when cooperatively interacting, like this when clamping column forging, stressed more stable, and can prevent column forging from slipping down from the opening part between two clamping bars, two pieces of grip blocks 6 are welded with at the end of the bare terminal 5 of every root clamping bar, grip block 6 is square iron plate, and the surface of the curved setting of contact surface 7 of grip block 6 and column forging is formed and fits, when like this column forging being clamped, the area of contact with column forging can be increased, clamp more stable, and be not easy to cause damage in clamping process, and zig-zag is also arranged in the end of grip block 6, such two pieces of grip blocks be oppositely arranged 6 can engage each other when clamping, ensure that the stability of clamping, this makes it possible to allow column forging better steadily carry, the phenomenon that can not fall, as preferably, to fit on the surface of grip block 6 one deck rubber pad, the friction force with column forging surface can be increased like this, anti-sliding stop, but also can prevent clamping bar from producing frictional loss to column forging, thus ensure that vestige when can not leave clamping on column forging surface.

Through hole is offered at 2/3 place of the distance grip block 6 of two clamping bars, then attaching parts 4 is fed through through hole, attaching parts 4 is a columned iron prop, after being fed through through hole, two clamping bars during the welding iron block of the two ends of attaching parts 4 are limited on attaching parts 4 and can only rotate, namely articulated structure is formed, such setting can ensure the connective stability of holding part 3, why being arranged on apart from 2/3 place of grip block 6 by hinge-point is to ensure that bare terminal 5 can have enough spaces to hold column forging, and when weight-lifting equipment utilizes holder column forging, can ensure that column forging is clamped by enough large Clamping force, also through hole is offered in the upper end of holding part 3, convergence part 2 is connected with in through hole, convergence part 2 is made up of two mild steel link chains, the other end of two mild steel link chains all snaps onto on clasp 1, clasp 1 is the iron ring of an annulus, the effect of clasp 1 be snap onto weight-lifting equipment hook on whole fixture and column forging are sling.

When using this fixture to carry out clamping carrying to column forging, first clasp 1 is snapped onto on the hook of weight-lifting equipment, then the bare terminal 5 of holding part 3 is placed in the both sides of column forging, then weight-lifting equipment is by clasp 1 pull-up, now the chain of convergence part 2 is exceptionally straight pulls two clamping bars, two clamping bars are stressed needs closing, bare terminal 5 is stressed herein clamps column forging when needing to close up, to engage each other between two pieces of grip blocks 6 and contact surface 7 forms fit-state with the surface of column forging, then weight-lifting equipment continues column forging to lift to move to assigned address, so just reach and facilitate gripping column forging, be less likely to occur to slide the object of phenomenon of falling, and be not easy to produce catcher mark to column forging in clamping process, column forging can be protected by actv..

The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
