Abstract

The utility model discloses a curling machine die head. The curling machine dire head comprises a fixing disk and a limiting disk. The diameter of the fixing disk is less than that of the limiting disk. The fixing disk and the limiting disk are integrally formed and fixedly connected and the center of the fixing disk and the center of the limiting disk are located on the same axis. A through hole is formed in the center of the fixing disk and the center of the limiting disk, a clamping ring is arranged between the inner wall of the through hole and the outer wall of a bearing, the clamping ring is connected with the upper portion of the bearing in a clamping mode and an annular groove is formed inside the middle end face, fixed into the through hole, of the bearing. The curling machine die head has the obvious advantages that the bearing of the curling machined die head is fixed more stably, so that the curling machine die head is more stable during running and a curling machine runs stably when processing workpieces, therefore, the workpiece processing quality is guaranteed, the production efficiency is improved and the production cost is saved.

Description

Crimping machine die head

Technical field

The utility model relates to metallic plate technical field of processing equipment, is specifically related to a kind of crimping machine die head.

Background technology

At present, crimping machine is as a visual plant in strip workshop shear line, and the stability of its work, reliability directly affect the subsidiary operation time of whole piece unit, and then affect the operating efficiency of whole piece unit.And bearing is the important spare part in machine driving, when bearing moves in high temperature, airtight, complex environment, the reliability of bearing is just particularly important.

Yet in prior art, the bearing in most of crimping machines does not all have mounting limit fixture, bearing is installed built on the sand, when crimping machine moves, can cause the rotation of bearing unstable, and then may affect operating efficiency and the safety in production of whole unit.Especially add again the larger crimping machine die head of stressed intensity in man-hour, for antiwhip, require higher.

Utility model content

The utility model is for the deficiencies in the prior art, and object is to provide a kind of bearing that makes and installs firmly, crimping machine die head that can be stable.

For achieving the above object, the utility model is explained a kind of crimping machine die head, comprise fixed disk and position-arresting disk, the diameter of described fixed disk is less than position-arresting disk, described fixed disk and position-arresting disk be one-body molded be fixedly connected with and the center of circle on an axis, at the circle centre position of described fixed disk and position-arresting disk, have through hole, bearing is installed in through hole, its key is: between described through-hole wall and bearing outer wall, be provided with snap ring, described snap ring is connected in described bearing top, and bearing is fixed in described through hole.

Above crimping machine die head middle (center) bearing, snap ring is set, bearing is better fixed on to installation site, can make crimping machine die head more stable when operation, make crimping machine stable operation when processing work, guarantee the crudy of workpiece, enhance productivity, can increase the service life of crimping machine die head simultaneously.

In described through hole, on the inside of end face, have cannelure, described snap ring is connected in described cannelure.

Cannelure is set and snap ring is connected to wherein, can be more firm so that bearing is fixed, like this, can guarantee the stability of crimping machine die head when processing operation.

The size of considering crimping machine die head in practical condition, the degree of depth of described cannelure is 2mm.

Described snap ring is " c " shape structure, at the both ends of described snap ring, is all fixedly connected with lug, has circular mounting hole on described lug.

" c " shape structure can, so that the snap ring that rigid material is made has the characteristic of certain deformation, be convenient to the installation of snap ring and shed; By installing hole, can be convenient to use instrument and make snap ring generation deformation, carry out easily the replacing of bearing and install.

Described snap ring is that spring steel is made.

During actual production, consider that crimping machine adds that run up man-hour and crimping machine die head is subject to force intensity larger, so snap ring is spring steel, make, thereby guarantee service life of snap ring, save cost, spring steel has elastically-deformable characteristic simultaneously, is convenient to install and changes.

Remarkable result of the present utility model is: the bearing of this crimping machine die head is installed firm, can stable operation, and with low cost, make crimping machine die head more stable when operation, make crimping machine stable operation when processing work, guarantee the crudy of workpiece, enhance productivity.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Referring to Fig. 1-4, a kind of crimping machine die head, comprise fixed disk 1 and position-arresting disk 2, the diameter of described fixed disk 1 is less than position-arresting disk 2, described fixed disk 1 and position-arresting disk 2 be one-body molded be fixedly connected with and the center of circle on an axis, at the circle centre position of described fixed disk 1 and position-arresting disk 2, have through hole 3, between described through hole 3 inwalls and bearing 4 outer walls, be provided with snap ring 5, described snap ring 5 is connected in described bearing 4 tops, and bearing 4 is fixed in described through hole 3.

Referring to Fig. 2-3, described snap ring 5 is " c " shape structure, at the both ends of described snap ring 5, is all fixedly connected with lug, has circular mounting hole 7 on described lug.

From Fig. 4, it can also be seen that, on the inside of described through hole 3 end faces, have cannelure 6, described snap ring 5 is connected in described cannelure 6.The degree of depth of described cannelure 6 is 2mm.

Described snap ring 5 is made for spring steel.

Although below by reference to the accompanying drawings preferred embodiment of the present utility model is described; but the utility model is not limited to the above-mentioned specific embodiment; those of ordinary skill in the art is under enlightenment of the present utility model; under the prerequisite without prejudice to the utility model aim and claim; can make like multiple types and representing, within such modification, equivalents all fall into the utility model protection domain.
