SU34459A1 - Pedal mechanism for controlling the glass blowing mold for blowing balls - Google Patents

Description

The invention is intended to facilitate the work of a glass blower to balls in sliding form: by applying two pedal mechanisms that serve both to lower and form into water when pressing one pedal, and to close one half while pressing the other pedal. time, as the second half of the form is brought to the closed position by the weight of the load when the first pedal is released; with the release of the second pedal, both halves of the form open.

In drawing 1, a side view of the pedal mechanism is shown, and FIG. 2 - view from above.

Three horizontally mounted 30, 31 and 36 are installed in the frame /. The pedal 4 is fixed on the shaft, equipped with a counterweight 5 and designed to open and close the form 38. The pedal 39 is attached to the base to lift and lower the latter into the water 35 with a loop 40 and zanna through the crank 19, 20 jc shaft 5 /, which is fixed to the crank 75, connected to the cracker /. Through rusk 4J, a ha / 7 is passed, connected at the other end with a crank lever 6 mounted on shaft 30. A cross / 2 is seated on the same shaft, through which form holder 8 is passed with weight 9 at one end and sliding form 38 on the other. .

The pedal 4 on the shaft 37 is connected to a cracker 23, through which a ha 3 is passed, fastened to a crank 7, worn tightly on the shaft 55, also carrying two cranks 37, mounted on it, of which one is connected to the lever f6, . and the other with a heck / 5. The lever J6 is connected to the carriage 33, which sits on the shaft 30 and carries the cracker 77 with the hook 7, which serves to open and close the form 38. the shaft 30, like the carriage 33, provided with a shank, is connected by a spring J4 to the end of the latch 75. The carriage 34 carries the biscuit 77 with another JO of the form 38 hook.

When the foot pedal 39 is pressed, the parts 20, 19, 57, 18, 41, 17, 6, 30, 12, 13 and 8 are activated, and the form 38 rises from the water tank where it has cooled. The crank 6 rests on the support 22 on the frame 2, in order to fix the form fixedly, and the bar 13 limits the lifting of the form, opened by the lever 16.

In the figure, the blow mold is shown in a raised position.

The blower inserts a tube with a jar into the neck of the right half of the mold and presses the pedal 4 with his right foot, as a result of which

 25, 5, 7, 56, 37, 37, 16 and / 5, with the latch 75 sliding along its neck along the bolt 42, the spring 14 is pulled out, and the carriage 55 with the biscuit 11 and the hook 10 covers the left half of the mold.

At the end of the balloon blowing, when the pedal 4 is released, the counterweight 5 reverses the movements of the parts 23, 3, 7, 36, 37, 57, b, 15, 33, 11, 10, 34, P, 10 and both halves of the form open moreover, the lever 16 abuts against the stop bar / 5 to restrict the movement of said parts. When releasing the pedal 39, the form 38 under the action of its own weight is lowered into the water tank, with the crank 6 resting on the stop 2 /, protecting the tank from damage, and the cross / 2 turning together with the stop bar 75, as a result of which the counterweight 5 descends to. the end. When the mold is lowered, the angle between the latch 75 and the carriage 34 from the straight goes to the sharper, the latch 75 fits into the shoulder 28, which is attached to the shaft 30. At the same time, S moves the carriage 34, which causes the bolt 42 to drop into the slot of the latch 75, thanks to what spring M,

getting rid of the bolt 42 holding it, brings the carriage 5- back, as a result of which the cracker 77 and the hook 70 move back, which cover the right half of the mold.

The form is located at a higher level of the pedals, which allows the blower to blow in a normally bent state, and the machine mechanism is in an open state, which allows for quick repair and lubrication.

The subject matter of the invention.

Pedal mechanism For controlling the glass-blowing form for blowing balls, characterized in that, for the purpose of simultaneously opening both halves of the form and forcibly closing only one of them, the 1st half of the mate is attached using H hooks with 30 carriages mounted on the shaft 55 and 5, the first of which is connected to the lever 3 76, and the other to the crank Shchekolda 75, equipped with a curved slot, into which the bolt 42 attached to the carriage drops, after which the carriage, under the action of the spring J4, is retracted, closing accordingly half of the form.
