SU373164A1 - PRESS FOR HOT VOLCANIZATION NOSE SHOES - Google Patents

Description

one

Known presses for hot vulcanization of the bottom of the shoe, containing a node of dual heated pads, a mechanism for moving the pads, a vulcanization mold with heated semi-matrix movable from the drive and a punch.

In known presses, there is no provision for the use of a hot-molding unit for a trace of shoes, which leads to a decrease in productivity.

The proposed press as compared to the known one is different in that in order to increase labor productivity, by combining the vulcanization of the bottom of the shoe and the hot forming of the workpiece trace, the press is equipped with a hot forming unit of the workpiece trace, made in the form of a heated matrix, which is hinged on the axis of the lever equipped with spring-loaded pushers and connected with a slide, movable in the guides from the drive, moving the die.

The press is also distinguished by the fact that the drive for moving the die is made in the form of a movable body of the power cylinder connected by means of a cracker to the slider of the lever for fastening and moving the die.

FIG. Figure 1 shows the pneumokinetic design of the press; in fig. 2 - press, front view; in fig. 2a - press, view along arrow B.

On the bed / mounted all the mechanisms of the press. The assembly 2 of dual heated shoes is located in the guides 3 and is connected to the cylinder 4 of the movement of the shoes.

Site 5 vulcanizing heated mold is located under the site of the pad 2 and is equipped with a pneumatic cylinder 6.

The hot forming unit of the billet trail consists of a matrix 7, equipped with a thermoelement and fixed lever hinged on the axis 8 of the lever 9. The lever is equipped with two spring-loaded pushers 10 and is connected with a slider 11 located in the guide 12. The slider 13 is connected through a biscuit 13. with the power cylinder 14, the brush 15 of which is fixed on the bed /.

To adjust the lower position of the cylinder 14, an adjusting bolt 16 is fixed on the frame.

The press for hot vulcanization of the bottom of the shoe contains a knot of dual heated pads, a mechanism for moving the pads, a vulcanization mold with heated movable semi-matrixes and a punch.

The press is equipped with two working sections, on which the rights and the left half of the pair of shoes are processed. The press works as follows.

In the initial position, the node of the dual heated pads 2 is raised above the node of the vulcanization mold 5, the node of the hot molding of the workpiece trace is raised above the node of the pads 2.

On the top block of the knot 2 wear the shoe stock. With the help of a hot-molding unit, a trace of the blank is put on the shoe. At the end of the molding process, the matrix 7 is lifted, and the assembly of the pads 2 is rotated by 180 ° so that the block with the molded wake is located above the vulcanization mold 5 unit. The rubber mixture is loaded into the mold 5, the half-matrix is closed by means of the pneumatic cylinder 6 and the cylinder 4 is lowered node pads 2 at the opening of the mold 5. The process of curing the bottom of the shoe begins. On the top pad of the pad assembly 2, the workpiece is put on with the help of the power cylinder 14 through the cracker / 5 ,. slider // together with the lever 9, the matrix 7 is lowered onto the trail of the workpiece. The process of forming a trail of the workpiece begins. Since the time of formation of the workpiece trace is less than the time required for the vulcanization process, after the completion of the molding, the matrix 7 is raised to the upper position.

At the end of the process of vulcanization of the bottom of the shoe, the semi-matrix of the vulcanization mold 5 is pushed apart by means of the pneumatic cylinder 6, and the assembly of the twin shoes 2 is lifted to the upper position by means of the cylinder 4.

The pad assembly 2 is rotated 180 °, ready shoes are removed from the upper pad,

the vulcanization mold 5 places the rubber mixture, the semi-matrices of the vulcanization mold 5 is closed, the pad assembly 2 is again lowered into the lower position, a new billet is put on the upper shoe, etc. The cycle of the press operation is thus continuously repeated. This press provides increased productivity by combining the vulcanization of the bottom of the shoe and the hot trace of the workpiece.
