Abstract

A three-dimensional closed tire grabber of a vulcanizer belongs to the technical field of vulcanization production of automobile tire capsule semi-finished products. The claw piece is a spiral piece or an arc piece with inclination, the spiral piece or the arc piece is uniformly arranged along the same rotation direction of the circumference of the fixed disc, and the whole claw piece is projected to be cylindrical. The utility model discloses a not changing the basis that former manipulator grabbed child ware structure, combining former manipulator claw piece processing method, designing and manufacturing, with open manipulator claw piece, change into totally enclosed claw piece structure. When the tire is grabbed, the contact area of the tire grabber and a semi-finished seam allowance can be ensured, and meanwhile, the claw sheets processed by adopting a spiral 10-degree cutting method always ensure that the whole claw sheets of the tire grabber are in a closed cylinder state no matter 8 claw sheets are in an open or closed state when seen from the upper side of the tire grabber, so that the requirement of claw sheet tire loading closing and sealing is met, and the problem that a capsule is scratched is solved.

Description

Three-dimensional closed type tire grabber of vulcanizing machine

Technical Field

The utility model belongs to the technical field of automobile tire capsule semi-manufactured goods vulcanizes production, especially relate to a three-dimensional closed tire ware of grabbing of vulcanizer, be applied to and vulcanize production process.

Background

The automobile tire bladder is an indispensable component for vulcanizing a vulcanizing machine, and the appearance of the bladder directly influences the vulcanization quality of the tire. If the vulcanizer bladder is damaged during tire loading, personal injury to the operator may also occur.

The ring-mounting lifting of the capsule of the existing manipulator vulcanizing machine is realized through power water, and two sides of the capsule are realized through a set of valve banks, so that the falling position of the capsule cannot be detected, and the capsule is completely controlled by time. Therefore, when the capsule descends after being shaped, if the capsule on one side is folded and squeezed to a gap between two claw sheets of the tire grabber, the edge of each claw sheet can damage the capsule, and the capsule can be directly scrapped seriously. Therefore, when the bladder descends, the gap between the claw sheets of the tire grabber needs to be as small as possible or no gap exists, and the tire blank can be placed into the vulcanizing machine only by closing the claw sheets of the tire grabber after the tire is loaded, so that the claw sheets of the traditional tire grabber cannot meet the requirement.

The claw pieces of the traditional manipulator are vertical to the horizontal plane, and when the manipulator is in an opening state and a closing state, gaps of more than 30mm are reserved between the claw pieces, so that after a green tire is loaded into a central mechanism of a vulcanizing machine, if a pleating place of a capsule enters a gap of the claw pieces, the edge parts of the claw pieces can damage the capsule.

SUMMERY OF THE UTILITY MODEL

Aiming at the technical problems, the three-dimensional closed type tire grabber for the vulcanizing machine is provided, and can always ensure that all the claw sheets of the tire grabber are in a closed state under the opening and closing actions when the vulcanizing machine is used for loading a pot; guarantee the normal life of vulcanizer capsule, reduce the manipulator scratch problem.

The purpose of the utility model is realized through the following technical scheme:

the utility model relates to a three-dimensional closed tire grabber of vulcanizer, including the claw piece, the claw piece is the flight or has the arc piece of inclination, follows the same rotation of fixed disk circumference and evenly sets up, and whole claw piece projection becomes a cylindric.

Further, the helix angle or slope α of each of the claws is 9 to 11 °, i.e. the angle α between the edge line of the claw and the vertical line is 9 to 11 °.

Further, the claw piece width W is 80-120 mm.

Further, the gap L between two adjacent claw sheets is 20-100 mm.

Furthermore, the cross section of each claw piece is arc-shaped, and the radian of the same cross section of each claw piece is the same.

Further, the outer diameter of the integral claw piece when the integral claw piece is opened is 3-5mm larger than the inner diameter of the tire blank, and the inner diameter of the integral claw piece is in contact with the inflated tire bladder.

Further, the outer diameter of the integral claw piece is 30-40 mm smaller than the diameter of the tire spigot when the integral claw piece is closed, the claw piece is contacted with the tire spigot when the integral claw piece is opened, and the inner diameter of the claw piece is 1-2mm larger than the diameter of the tire spigot.

The utility model has the advantages that:

1. the utility model discloses a not changing the basis that former manipulator grabbed child ware structure, combining former manipulator claw piece processing method, designing and manufacturing, with open manipulator claw piece, change into totally enclosed claw piece structure.

2. The utility model discloses the claw piece adopts helix angle or oblique angle to be 9-11 degrees cutting methods, cuts apart into even a plurality of the same claw pieces with the drum, circularity when guaranteeing to install 8 claw pieces dress child on the fixed disk.

3. Because of adopting seamless cutting, the manipulator can guarantee the contact area with the semi-finished seam allowance when grabbing the child, simultaneously because adopt the helical angle or the oblique angle is the claw piece of 9-11 degrees cutting processing of degree, look from grabbing the child top, no matter 8 claw pieces are open or closed state, guarantee to grab whole claw piece of child ware and be the closed drum state all the time, thereby reached the claw piece dress child closed confined requirement, solved the problem that the capsule is scratched.

In the figure: 1. the device comprises a fixed support, 2 a claw piece opening and closing cylinder, 3 a rotating disc, 4 claw pieces, 5 a fixed disc, 6 a precision adjusting block, 7 a claw piece opening and closing sliding block and 8 a cutting line.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Example (b): as shown in fig. 1 and 2, the utility model relates to a three-dimensional closed tire grabber of vulcanizer, including claw piece 4, fixed disk 5, rotary disk 3, precision adjusting block 6, claw piece open and close cylinder 2, claw piece open and close slider 7 and fixed bolster 1, claw piece 4 is the flight or has the arc piece of inclination, follows the same rotation of fixed disk 5 circumference and evenly sets up, and whole claw piece projection becomes a cylindric.

The outer diameter of the whole claw piece is 3-5mm larger than the inner diameter of the tire blank when the whole claw piece is opened, and the inner diameter of the whole claw piece is contacted with the inflated tire bladder. The outer diameter of the whole claw piece is 30-40 mm smaller than the diameter of the tire seam allowance when the whole claw piece is closed, the embodiment adopts 35mm, the claw piece 4 is contacted with the tire seam allowance when the whole claw piece is opened, and the distance between the two opposite claw pieces is larger than the diameter of the tire seam allowance by 1-2 mm.

As shown in fig. 3-4, each of the claws 4 has a helix angle or pitch α of 9-11 °, in this case 9.34 °, i.e. the angle α between the edge line of the claw 4 and the vertical line is 9.34 °. The width W of the claw sheet 4 is 80-120mm, and 118mm is selected in the embodiment; the clearance L between two adjacent claw sheets 4 is 20-100 mm.
