Description
Technical Field
The present utility model relates to a lapel shaper, and more particularly, to a lapel shaper with improved manufacturing accuracy.
Background
The lapel former with the highest dosage in the bag making and packaging machine is formed by a sheet metal process, wherein the simplest lapel former is formed by bending a shoulder curved surface, a back plane and a vertical pipe by stainless steel plates with different thicknesses; the lapel shaper with high precision requirement is formed by combining a vertical pipe processed by a processing center and a shoulder curved surface formed by bending a stainless steel plate. The vertical pipe machined by the machining center machine tool is higher in size precision and shape precision than the vertical pipe coiled by a sheet metal process, but the shoulder curved surface is manually manufactured, and the manufacturing precision depends on the skill of an operator. Another factor in manufacturing errors is that the axial positions of the shoulder curved surface and the diameter of the stand pipe are offset, when the shoulder curved surface is mounted on the stand pipe in the process of manufacturing the lapel shaper, the outer diameter of the stand pipe just forms radial limit of the shoulder curved surface, and is not positioned in the height direction, a mounting line is subjected to laser lithography, and depending on visual positioning of workers, the edge of the inner ring of the shoulder curved surface cannot just conform to the theoretical three-dimensional intersecting line due to manual bending, so that displacement deviation with different degrees is generated in the height direction within the whole 360 DEG range in the process of assembly welding, the manufacturing precision is reduced, and the bag manufacturing quality is affected.

Description of the embodiments
The following describes the embodiments of the present utility model in further detail with reference to the drawings.
As shown in fig. 1-4, the utility model comprises a cylindrical vertical pipe 1, a back plane 3 and two shoulder curved surfaces 2 symmetrically arranged on two sides of the vertical pipe, wherein a positioning step surface 4 is arranged at the outer edge of the top surface of the vertical pipe 1, the shoulder curved surfaces 2 and the back plane 3 are connected with the vertical pipe 1 through the positioning step surface 4 and welded with the vertical pipe 1, the bottom surface 41 of the positioning step surface 4 is an offset surface of the shoulder curved surface, and the vertical surface of the positioning step surface 4 is an arc surface equidistant with the inner hole of the vertical pipe 1.
In the utility model, a positioning step surface 4 is processed on the vertical pipe 1 and is used as a positioning reference of the shoulder curved surface 2 and the back plane 3 in the height direction. The normal distance between the step surface and the theoretical curved surface of the shoulder curved surface is equal to the thickness of the shoulder curved surface steel plate. Because the included angles between the shoulder curved surface and the axis of the vertical pipe are different everywhere, the step surface cannot be obtained by shifting the thickness of a shoulder curved surface steel plate in the height direction by the theoretical shoulder curved surface, and cannot be obtained by multiplying the thickness of the steel plate by a coefficient, and the step surface cannot be obtained by a curved surface shifting method when the three-dimensional design of the vertical pipe is performed. According to the utility model, the assembling mode of the shoulder curved surface, the back plane and the vertical pipe is changed, so that the operation difficulty of workers is reduced, the manufacturing precision of the lapel shaper is improved, and the bag making quality is ensured.
