Abstract
The utility model discloses a tire building machine transfer ring grabbing piece, which relates to the technical field of tire building and comprises a grabbing piece body, wherein the grabbing piece body comprises a connecting piece and an arc-shaped plate, one end of the connecting piece is fixed at the center of the back of the arc-shaped plate, a plurality of radial embedded nails are arranged on the arc-shaped plate, the embedded nails are distributed in a staggered manner in the circumferential direction, and a plurality of strong magnetic sheets are uniformly distributed on the arc-shaped plate; the embedded nails are distributed in a staggered manner in the circumferential direction, so that the embedded nails can not fall into grooves on the surface of the crown compound, and the grabbing firmness of the grabbing piece is improved; the strong magnetic sheet plays a role in adsorbing the tire crown to offset the magnetic attraction of the belt drum, so that the grabbing reliability is further improved, and the occurrence of anomalies such as grabbing deformation, dropping and the like of the tire crown compound is avoided.
Description
Technical Field
The utility model relates to the technical field of tire building, in particular to a transfer ring grabbing piece of a tire building machine.
Background
In the production process of the tire building machine, the crown compound is required to be transferred from the belt drum to the building drum through the transfer ring grabbing piece so as to complete the tire embryo building process, the transfer precision directly determines the tire embryo building precision and has great influence on the dynamic homogeneity of the finished tire, so that the transfer ring grabbing piece is used for grabbing the crown compound reliably and firmly in the whole transfer process.
The existing transfer ring gripper contacts with the crown compound through an arc surface, and the gripping is completed under the condition of applying a certain pressure. Because the distribution difference of grooves on the surface of the crown compound is large, and the magnetism of the belt drum sheets can generate suction force on the steel belts in the crown compound in the grabbing process, the phenomenon of loose grabbing exists in part of specifications, so that the crown compound is grabbed, deformed and dropped, and the molding precision of the embryo, the dynamic balance of the finished product and the quality of uniformity are seriously affected. In this case, it is necessary to develop a new transfer ring gripper to promote the gripping reliability of the crown compound.
Disclosure of Invention
In order to improve the gripping reliability of the crown compound, the present utility model provides a tire building machine transfer ring gripper.
The technical scheme of the utility model is as follows: the utility model provides a tire building machine transfer ring grabs piece, includes grabs the piece body, grabs the piece body and includes connecting piece and arc, and the one end of connecting piece is fixed in the back center department of arc, install a plurality of radial inserts on the arc, a plurality of inserts in circumference staggered distribution, the equipartition has a plurality of strong magnetic sheets on the arc.
Preferably, the arc plate is provided with a plurality of mounting holes matched with the insert nails, the insert nail threads are arranged in the mounting holes, and the insert nails are provided with fastening nuts.
Preferably, the back of the arc plate is provided with a plurality of circular grooves, and the strong magnetic sheet is circular and is embedded in the circular grooves.
Preferably, the material of the strong magnetic sheet is neodymium iron boron magnet.
Compared with the prior art, the utility model has the following advantages:
the embedded nails are distributed in a staggered manner in the circumferential direction, so that the embedded nails can not fall into grooves on the surface of the crown compound, and the grabbing firmness of the grabbing piece is improved; the strong magnetic sheet plays a role in adsorbing the tire crown to offset the magnetic attraction of the belt drum, so that the grabbing reliability is further improved, and the occurrence of anomalies such as grabbing deformation, dropping and the like of the tire crown compound is avoided.
Drawings
FIG. 1 is a schematic perspective view of the present utility model;
fig. 2 is a schematic cross-sectional view of fig. 1.
In the figure: 1. the connecting piece, 2, the arc, 201, the mounting hole, 202, circular recess, 3, inlay nail, 4, fastening nut, 5, strong magnetic sheet.
Detailed Description
The utility model is further illustrated by the following examples in connection with the accompanying drawings.
Example 1
Referring to fig. 1-2, a tire building machine transfer ring grabs piece, including grabbing the piece body, grab the piece body and include connecting piece 1 and arc 2, the one end of connecting piece 1 is fixed in the back center department of arc 2, installs a plurality of radial inserts 3 on the arc 2, and a plurality of inserts 3 are crisscross to be distributed in circumference, have a plurality of strong magnetic sheets 5 on the arc 2 equipartition.
In the grabbing process, the embedded nails 3 are distributed in a staggered manner in the circumferential direction, so that the embedded nails 3 can not fall into grooves on the surface of the crown compound, and the grabbing firmness of the grabbing piece is improved; the strong magnetic sheet 5 plays a role in absorbing the crown to offset the magnetic attraction of the belt drum, further improves the grabbing reliability and avoids the occurrence of the anomalies such as grabbing deformation, dropping and the like of the crown compound.
In the transfer process, the strong magnetic sheet 5 can play a role in stably grabbing, so that the crown compound caused by movement inertia is effectively prevented from dropping, skewing and other anomalies.
Example two
As a preferred embodiment of the present utility model, the present embodiment designs the mounting manner of the insert pin 3 and the strong magnetic sheet 5 based on the first embodiment, specifically:
in the embodiment, a plurality of mounting holes 201 matched with the insert nails 3 are formed in the arc-shaped plate 2, the insert nails 3 are arranged in the mounting holes 201 in a threaded manner, and fastening nuts 4 are arranged on the insert nails 3; this arrangement facilitates replacement of the insert 3.
The back of the arc plate 2 is provided with a plurality of circular grooves 202, and the strong magnetic sheet 5 is circular and is embedded in the circular grooves 202. The material of the strong magnetic sheet 5 is neodymium-iron-boron magnet.
The present utility model is not limited to the above-described embodiments, and various changes may be made without departing from the spirit of the present utility model within the knowledge of those skilled in the art, and the contents after the changes still fall within the scope of the present utility model.
