Abstract
The utility model provides a take claw bearing holder production materials area, it includes expects to take the body, the material is taken on the body to be provided with with the junction of bearing holder claw and is used for the tensile movement joint that warp. The bearing holder claw is all taken with the material and is connected, and leaves the movement joint at hookup location, and when keeping the tensile shrink of ware, the movement joint magnifies to messenger's material is taken indeformablely, guarantees the walking production smoothly on the mould of material area, and bearing holder's stability increases, expects the strength increase in area, effectual dimensional stability and the pay -off precision of having guaranteed bearing holder. At bearing holder's finishing operation, use handle for die block bearing holder claw all to cut off with expecting the area, guaranteed the uniformity of all bearing holder claws, avoided the inconsistent problem that causes because the gradation is cut off among the prior art.
Description
Technical field
The utility model relates to a kind of band pawl bearing cage, especially a kind of band pawl bearing cage production material strip.
Background technology
Zanjon spherical zone pawl retainer generally adopts progressive die material strip to produce, and at present, the progressive die tape connection mode on market is all that the both sides external diameter of retainer is connected with material strip, as shown in Figure 1.In this connected mode, when retainer stretches contraction, very easily cause the pawl of connection crooked, as shown in Figure 2, thus cause the angle of retainer pawl defective.And in process of production, retainer pawl for connecting is last and material strip cuts off, and is not cut off with other retainer pawls simultaneously, so just cause two of connection retainer pawls and other retainer claw shape inconsistent, cause customer complaint, the weak point that Here it is existing for prior art.
Utility model content
The technical problems to be solved in the utility model, be exactly for the deficiency existing for prior art, and a kind of band pawl bearing cage production material strip is provided, retainer pawls all in this material strip is all connected with material strip, when retainer stretches contraction, movement joint magnifies, thus makes material strip indeformable, effectively ensure that dimensional stability and the pushing precision of retainer.
This programme is achieved by the following technical measures: this band pawl bearing cage production material strip comprises material strip body, described material strip body is provided with the movement joint for stretcher strain with the junction of bearing cage pawl.
Above-mentioned movement joint is arc-shaped slit.
Each movement joint is connected to form a circle in turn.
Leaving certain gaps uncovered by the economic plan between adjacent deformations seam.
The internal diameter of above-mentioned movement joint is equal with the external diameter of bearing cage pawl.
Above-mentioned breach is the recess of outward opening, and the openend of breach is positioned at the outer ledge corresponding position with movement joint.
The beneficial effects of the utility model:
1, bearing cage pawl is all connected with material strip, and leaves movement joint at link position, retainer stretch shrink time, movement joint magnifies, thus makes material strip indeformable, ensures that material strip is walked smoothly production on mould;
2, at the finishing operation of bearing cage, use mould that bearing cage pawl is all cut off with material strip, ensure that the uniformity of all bearing cage pawls, avoid the inconsistence problems caused due to gradation cut-out in prior art;
3, bearing cage and material strip are all connected by bearing cage pawl, and the stability of bearing cage increases, and the intensity of material strip increases, and effectively ensure that dimensional stability and the pushing precision of bearing cage.

In figure, 1-material strip body, 2-bearing cage pawl, 3-movement joint, 4-bearing cage, 5-breach.
Detailed description of the invention
For the technical characterstic of this programme can be clearly demonstrated, below by detailed description of the invention, and in conjunction with its accompanying drawing, this programme is set forth.
A kind of band pawl bearing cage production material strip, as shown in the figure, it comprises material strip body 1, bearing cage pawl 2 is all connected with material strip body 1, described material strip body 1 is provided with the movement joint 3 for stretcher strain with the junction of bearing cage pawl 2, described movement joint 3 is arc-shaped slit, and each movement joint 3 is connected to form a circle in turn, and the internal diameter of movement joint 3 is equal with the external diameter of bearing cage pawl 2.When bearing cage 4 stretch shrink time, movement joint 3 is large, thus makes material strip body 1 indeformable, ensures that material strip body 1 is walked smoothly production on mould.Bearing cage 4 is all connected by bearing cage pawl 2 with material strip body 1, and the stability of bearing cage 4 increases, and the intensity of material strip body 1 increases, and effectively ensure that dimensional stability and the pushing precision of bearing cage 4.
In order to ensure that material strip body 1 can not be out of shape further, leaving certain gaps uncovered by the economic plan 5 between adjacent deformations seam 3, described breach 5 is the recess of outward opening, and the openend of breach 5 is positioned at the outer ledge corresponding position with movement joint 3.
In the last production process of bearing cage 4, use mould that bearing cage pawl 2 is all cut off with material strip body 1, ensure that the uniformity of all bearing cage pawls 2, avoid bearing cage pawl 2 inconsistence problems caused due to gradation cut-out in prior art.
Can pass through without the technical characteristic described in the utility model or adopt existing techniques in realizing; do not repeat them here; certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned embodiment; the change that those of ordinary skill in the art makes in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
