Abstract

The invention relates to an annular fluorescent lamp tube bender which is processing equipment for manufacturing annular fluorescent lamp tubes in a lamp tube enterprise. The invention overcomes the following defects: high labor intensity: the workers have to work in front of a high-temperature baking oven in the annular lamp tube bending process in a lamp tube enterprise; low work efficiency: only 100 lamp tubes can be made every hour; and skilled workers are required for operation in the bending process. The annular fluorescent lamp tube bender is composed of the following eight functional parts: a cutting mechanism, a feed mechanism, a preheating mechanism, a heating mechanism, a bending mechanism, a discharge mechanism, a discharge rack and a PLC (programmable logic controller) electric control system; and a machine frame organically integrates all the functional parts. The annular fluorescent lamp tube bender is provided with double station working modes; and the heating mechanism and the bending mechanism are arranged on both side of the feed mechanism. The workers are only in charge of feeding the material and transferring the bent lamp tube, and are far from the heating source, thereby reducing the labor intensity; and the PLC controls the movement sequence of all the mechanisms, thereby ensuring the high working efficiency.

Description

The circline tube bending machine

The present invention provides the processing mechanical apparatus that bends molding procedure in the annular lamp tube process of manufacture of a kind of illuminating lamp tube enterprise.

Energy-saving illumination instrument during annular fluorescent tube is produced, lived as people is because its energy-saving environmental-protection function more and more receives huge numbers of families' welcome.Fluorescent tube enterprise moon turnout has reached about 200,000 at present, and the mode of production is to adopt manual work on mould, bending moulding after the heating deliquescing on the baking oven.The workman is sitting in the combustion gas stove next door that Heating temperature reaches more than 800 degree and bends, and labour intensity is quite big, and efficiency ratio is lower, per hour can only bend about 100.

This annular lamp tube tube-bending machine is to make on the basis of annular lamp tube technical process in research fluorescent tube enterprise, bends the characteristic that is prone to brittle failure in the process according to fluorescent tube, through selecting suitable mechanism, a machine that designs.The function of the quick response of this machinery utilization PLC and multiple spot control, the characteristic of evading the easy brittle failure of fluorescent tube in the bending technique process, thereby it has yield rate height, advantage that labour intensity is low.This machine is per hour produced about 1200, is fit to very much the production demand of more than 20 ten thousand of fluorescent tube enterprise monthly outputs.

This machine is by material cutting mechanism [1], feed mechanism [2], and preheating mechanism [3], heating arrangements [4] bends mechanism [5], and shedding mechanism [6], unloading rack [7] and PLC electrical control system eight big funtion parts are formed, and frame is got up all functions part organic combination.Because operating ambient temperature is high, PLC unit and servo-driver are arranged in the housing separately, and are arranged in the place away from tube-bending machine.Combine the structural representation of this machine now, the technical scheme of this machine is explained.

The material seat [8] of this tube-bending machine becomes the angle of 10 degree along horizontal plane, and fluorescent tube can be rolled under action of gravity to blank wheel [9] automatically.The notch [a] of blank wheel [9] closes behind the wick of a fluorescent tube at every turn, forwards the predetermined position to, and wick is sheared, and the unnecessary length of wick is partly cut away.Blank wheel [9] is in the rotation work process; It is synchronous that the wick that has cut fluorescent tube leaves another notch [b] that notch [a] and fluorescent tube wick to be cut get into the blank wheel, so can not cause the fluorescent tube wick because do not get into the notch [a] of blank wheel [9] and occurred by the defective that blank wheel [9] breaks wick.Feed mechanism rotates a circle, feeding four times, and just [2] working cycle of feed mechanism have four stations.The public motor of material cutting mechanism [1] and feed mechanism [2] is as propulsion source, two inter-agency cooperation of moving through geartransmission, and the speed of motor and the Frequency Synchronization that bends that bends mechanism [5].

Preheating mechanism [3] mainly is made up of SV, well heater, drawing-inroller [10], propulsion source cylinder [11], rack-and-pinion [12], the sprocket wheel chain [13] of control burnt gas switch.The two-way rotation of drawing-inroller [10] realizes in the process of transporting, carrying out preheating simultaneously to the left and right fluorescent tube that transports.Drawing-inroller [10] can two-wayly rotate, on one side fluorescent tube carries out preheating, Yi Bian transmit under the power transmission effect that propulsion source cylinder [11], rack-and-pinion [12], sprocket wheel chain [13] are formed.Preheating mechanism [3] just begins heating behind machine startup, so that, prevent that the drawing-inroller temperature is not enough in the feeding process with drawing-inroller [10] heating, because bursting appears in chilling effect fluorescent tube.

Heating arrangements [4] mainly is made up of the SV and the well heater of control burnt gas switch.Heating arrangements [4] is only sending tube side when instruction is sent, and corresponding heating arrangements [4] just starting point coal gas heats.Heating arrangements [4] and preheating mechanism [3] adopt fluorescent tube enterprise coal gas commonly used to heat.

Bend mechanism [5] and mainly clamp finger [15] by the spacing mould of detection head, shaping [14] that detects lamp strip position, gear drive, fluorescent tube, the SV and the corresponding fixed frame that clamp finger movement cylinder [16], bending die [18], cylinder [19], servomotor [17], control cylinder action are formed.Detection head detects fluorescent tube arrival predetermined position, and to PLC transmission signal, PLC controls fluorescent tube again and clamps finger [15] then, and fluorescent tube is fixedly clamped, and servomotor [17] drive simultaneously bends mould and rotates a circle, and the fluorescent tube that heats deliquescing is bent moulding.In the process of bending, the spacing mould of shaping [14] is through the transmission of gear mechanism, and is the same with bending die [18] velocity of rotation value; All the time consistent with fluorescent tube speed; And spacing in the fluorescent tube outside, played and assisted shaping, spacing effect, thereby guaranteed the appearance that bends.The fluorescent tube folder is the thick part of clamping lamp tube end, rather than bends clamping wick in the process as manual work, thereby has evaded wick in the process of bending effectively because tiny, and the defective of stressed easy fracture makes that bending yield rate improves greatly.

Shedding mechanism [6] is mainly clamped cylinder permanent seat [29] and is formed by mechanical finger [21], Rodless cylinder [22], firm banking [23], upset cylinder [24], elevate a turnable ladder cylinder [25], mechanical finger clamping cylinder [26], upset cylinder permanent seat [27], elevate a turnable ladder air cylinder fixed plate [28], finger.Mechanical finger clamps cylinder [26] action and mechanical finger [21] interoperation, with the fluorescent tube clamping with unclamp; Elevate a turnable ladder cylinder [25] action is risen certain altitude with fluorescent tube, interferes so that escape the locus of the bending die that bends mechanism [5]; Rodless cylinder [22] transports fluorescent tube to discharging position; Upset cylinder [24] drives elevate a turnable ladder air cylinder fixed plate [28] and rotates 90 degree around fulcrum [c] after fluorescent tube arrives discharging position, and mechanical finger clamps cylinder [26] action release mechanism finger [21] simultaneously, and fluorescent tube falls under gravity to [7] on the unloading rack.

In machine running process, fluorescent tube to be bending is rolled into blank wheel [9] along material seat [8] under action of gravity, cuts away convenient follow-up bending through the wick of blank wheel [9] with unnecessary length.The fluorescent tube that is cut wick is sent to preheating mechanism [3] through feed mechanism [2].Through the rotation of the fluorescent tube of preheating in drawing-inroller [10], to carry down, the wear long middle flame of overheated mechanism [7] of fluorescent tube heats comprehensively.Fluorescent tube arrives after by rapid heating and bends mechanism [5], and servomotor [17] drives the bending die that bends mechanism [5] and turns around, and fluorescent tube is bent into type.Move with exhaust hood [19]; Bending die patrix [20] rises; The mechanical finger [21] of shedding mechanism [6] leaves after with the fluorescent tube gripping and bends mechanism [5]; Last material fetching mechanism is delivered to unloading rack [7] with fluorescent tube, and shedding mechanism [6] returns the starting position wait subsequently, thereby accomplishes a task that bends station.

It is the double operating mode that this tube-bending machine bends operation; Heating arrangements [4] and bend mechanism [5] and be arranged in the feed mechanism both sides; Become left and right bend pipe station, when the drawing-inroller of feed mechanism [10] clockwise changeed, fluorescent tube was sent to right bend pipe station; When the drawing-inroller of feed mechanism [10] inverse clock changeed, fluorescent tube was sent to left bend pipe station.Because left and right bend pipe station alternately bends fluorescent tube; Maximally utilise the time difference between the technology step in the process of bending; Adopt the quick response of PLC unit and the function of multiple spot control that the co-ordinate motion of each inter-agency working element is controlled again, thereby bend pipe efficient is high.Pipe bending mechanism [5] is in the process of bending, and the fluorescent tube feed direction is consistent with the turning direction of bending die, and the thick position of clamping element clamping fluorescent tube is not to bend in the process as manual work, the clamping wick, thus can wick not broken, guaranteed yield rate.
