Description

The shedding mechanism of helical lampl automatic molder

Technical field

The utility model relates to a kind of shedding mechanism of electricity-saving lamp helical lampl automatic molder.

Background technology

Chinese patent application file (ZL200820163402.3) discloses a kind of helical lampl automatic molder; Adopt behind this machine not only that the final product quality of helical lampl obviously improves (qualification rate improves more than 5%), energy-saving effect is (more energy-conservation more than 40% than making by hand) significantly, and production efficiency significantly improves, and working environment of operating personnel is improved greatly; Be subjected to the popular welcome of manufacturer.

This machine is in concrete use, and also realizing has part working mechanism need do further improvement; Especially after helical lampl bends and finishes, the shedding mechanism that still red-hot Glass tubing is taken out from die head; Its applicable scope and working reliability still have much room for improvement.

The utility model content

The purpose of this utility model is the deficiency that overcomes the above-mentioned background technology, and a kind of improvement of helical lampl molding device shedding mechanism is provided, characteristics applied widely, that working stability is reliable and cost is low that this feed mechanism should have.

The utility model has adopted following technical scheme:

The shedding mechanism of helical lampl automatic molder, comprise that one is equipped with the mechanism that folds up of chela, the chela frame of this mechanism is positioned on the horizontal guide rail of support slidably and is subjected to the reactive force of a horizontal air cylinder, the chela seat down stretches out from the bottom of chela frame and is subjected to a vertical air cylinder driven, it is characterized in that being installed with on the described chela seat two pairs of chelas that be arranged in parallel.

In the described chela seat, the both sides of one gear of vertically arranging are being meshed two tooth bars respectively, each fixes a clamping bar as moving pawl to two tooth bars again, the relative movement that each moving pawl is toward or away from fixed jaw work respectively under the driving of gear, and then the action of formation grasping Glass tubing; Other has one of them tooth bar of little air cylinder driven.

The opening of described chela down.

Principle of work of the present utility model is: when Glass tubing behind the work in-process D that is bent into lamp tube shapes on the die head 2, the intermediate plate of embracing of both sides clamp mechanism opens respectively and throws off with glass lamp work in-process (abbreviation work in-process) and each slides to the both sides of support along the guide rail that tilts; At this moment, horizontal air cylinder 11 start promoting chela frame 1 along horizontal guide rail 12 to front slide; When the chela frame reached desired location, vertically cylinder 13 started and promotes chela seats 19 and move down along the slideway 14 of chela frame, and the D1 of the elongated end that stretches outward until the work in-process both sides inserts respectively in two pairs of chelas 6 on the chela seat; After this die head 2 moves down while reversing driven vertically by main shaft 3; Because half-finished rotation is limited by two pairs of chelas, so the rotation of die head just makes work in-process screw out in the thread groove from die head rapidly; Last stingy cylinder 15 starts, the close fixed jaw 5-2 of the moving pawl 5-1 in each chela, and then firmly firmly grasping work in-process; Then horizontal air cylinder 11 reversing motions, chela frame 1 are being carried the glass lamp work in-process and are being moved toward the support side, reach specified location after each chela unclamp, the glass lamp work in-process just fall, and then are collected by unified.

It more than is the single job process of shedding mechanism; Continue above circulation, the half-finished discharging of glass lamp is just constantly carried out continuously.

The beneficial effects of the utility model are: because chela adopted the structure of moving pawl and fixed jaw, thereby can be applicable to the glass lamp of various pitch, the scope of application significantly enlarges, and more reliable and more stable during work, and broken pipe rate obviously descends, and has also reduced cost.

Embodiment

During unwinding, have and follow the trend that die head rotates, Fig. 2, the spiral slot of helical lampl work in-process from die head shown in Figure 3 so it is stable to need chela to control.And the both sides of helical lampl work in-process D shown in Figure 3 respectively have an elongated end D1 outwards outstanding, and these two elongated ends are just in time as the target site of chela grasping.

The shedding mechanism of helical lampl automatic molder comprises that one is equipped with the mechanism that folds up of chela, after the chela frame 1 of this mechanism is subjected to the reactive force of a horizontal air cylinder 11, can slide on the horizontal guide rail 12 of support; Chela seat 19 down stretches out from the bottom of chela frame and driven by a vertical cylinder 13, and two pairs of chelas that be arranged in parallel 5 are installed on the chela seat.

In the described chela seat 19, the both sides of one gear of vertically arranging 17 are being meshed two tooth bars 16 respectively, each fixes a clamping bar as moving pawl 5-1 to two tooth bars again, the relative movement that each moving pawl is toward or away from fixed jaw 5-2 work respectively under the driving of tooth bar, and then constitute the half-finished action of grasping glass lamp; When a stingy cylinder 15 drove one of them tooth bar, another tooth bar just was driven to another opposite direction.Because the direction of motion of two tooth bars is opposite, thus moving pawl 5-1 in another chela and fixed jaw 5-2 that position (as shown in Figure 7) is set is also opposite with chela shown in Figure 4; When stingy like this cylinder 15 started, two chelas were just in time done grasping simultaneously or are discharged the half-finished action of glass lamp.

Fig. 4 as can be known, the opening of described chela 5 is down; Like this, the helical lampl work in-process just can directly enter the chela from the bottom, directly fall from chela after perhaps chela unclamps.
