Description

New HE type serial plate machine of surface cooler

The utility model relates to the pitch of fins that the assembling of the efficient surface cooler of the copper-tube aluminium finned double-turnup of a kind of HE type uses adjustable, successively decrease, automatic control and big the ratio of width to height surface cooler machine for stringing.

Prior art only is working height＜2000 millimeter, area＜800 * 400(millimeter) ²The machine for stringing that belongs to a kind of simple and easy fin.This a kind of simple and easy machine for stringing is to utilize two motor transmissions, and structure space is big; When putting in place do feed motion downwards, because of the moment of inertia effect, rely on another motor plugging after, upwards return fast again, so control is inaccurate, power consumption is big, it is terrible to impact; Be contained in the gear-box of main frame bottom, be lower than ground level, so maintenance is had any problem; Double lead transmission synchronism can not be adjusted, and moving press plate feeding work is not steady, and noise is big, poor reliability.In addition, the pitch of fins control system of successively decreasing because its drive path is long, each transmission pay the gap add up excessive, poor structure rigidity, so system's instability, often cause that the pitch of fins control of successively decreasing lost efficacy, causes product rejection.

The purpose of this utility model is the problem at above-mentioned existence, proposes a kind ofly can satisfy full-size (volume 1400 * 400 * 3500(millimeter) ³), have distinguishing feature, steady quality, a pitch of fins easy to operate, that production efficiency is high is adjustable, successively decrease, automatic control and big the ratio of width to height surface cooler machine for stringing.

Technical solution of the present utility model: transmission system, be contained in the double-speed motor 2 on the reduction box 3, be to make screw mandrel 12 rotations by reduction gearing 8.Drive moving press plate 4 downward work feeds through nut 16, the template on it, seal in copper pipe with fin this moment, presses to pre-selected locations.Moving press plate 4 is down to behind the pre-selected locations, and the collision block 10 on it is pressed travel switch 1 * K, and motor 2 stops, and electromagnetic clutch ERD work influences thereby overcome moving press plate 4 downward inertia impulsions, makes its accurate location.Loosen after the electromagnetic clutch time-delay, motor 2 counter-rotatings, moving press plate 4 is upwards done fast return.After returning back up to the position, collision block 9 is pressed combination of travel switch, and at this moment, signal can divide the two-way transmission:

1, press 2 * K motor 2 to stop electromagnetic clutch work;

2, press the automatic control system work of successively decreasing of 3 * K pitch of fins, make control cabinet 11 and on travel switch 1 * K pitch of fins that moves up, so the stroke that moving press plate 4 moves just deducts a pitch of fins, in like manner, circulation n-1 the pitch of fins of just successively decreasing for N time.Control cabinet 11 can be realized quick adjustment and manually trace adjusting up and down separately.See Fig. 1 for details.

Reduction box 3 adopts overhead, promptly is arranged in the top of complete machine, so assembling is easily, and good manufacturability, maintenance is convenient; The double lead 12 of symmetric arrangement in the case, its synchronized movement is the important step that moving press plate 4 motions are steadily coordinated, realization means: (1) wire rod thread starting point B ₁Alignment keys groove center A ₁, nut 16 screw thread starting point B ₁Aim at by dress hole center C ₁(2) the consistent gear teeth tips center of aiming at, the protruding key of gear 8 end faces center; (3) design have can deciliter adjustment pad 13, by the axial dimension of increase and decrease screw mandrel 12, realize fine setting to its synchronism; (4) special part trough of belt cover 14 of design and the protruding key gear 8 of end face, turn adjustment screw 15 makes screw mandrel 12 and gear 8 that circumferential relative displacement take place, and reaches synchronous requirement.

A pitch of fins is successively decreased, automatic control, adjustable system, and when moving press plate 4 returns back up to the position, collision block 9 is pressed 3 * K beginning that circulates automatically, calibration alignment pin 17 is transferred to, and presses travel switch 4 * K, widely different rotating shaft 18 rotate 179 ° 45 ', drive freewheel clutch 19 and clockwise rotate, collision block 20 is pressed travel switch 5 * K, and calibration alignment pin 17 inserts locating slot, unclamp travel switch 4 * K, widely different rotating shaft 18 resets, and unclamps travel switch 5 * K, and circulation stops, so repeatedly, until finishing nearly 1625 periodic duties.

Widely different rotating shaft 18 drive locating slots are 180 ° ± 0 freewheel clutch 19, clockwise rotate simultaneously 179 ° 45 ', the difference 15 that its circumferential corner less than is 180 ° ', when inserting locating slot by alignment pin 17, rely on its P face, promotion freewheel clutch 19 clockwise directions rotation 15 ' compensate difference, this design feature has been eliminated the gap of system, has guaranteed that calibration work has higher precision.Freewheel clutch 19 is with clockwise rotation, through compound indexing change gear A, B, C, D and bevel gear 21 reach the feed

screw nut pay

22,23 make control cabinet 11 and on travel switch 1 * K pitch of fins that moves up, the pitch of fins so the stroke that moving press plate 4 moves has just successively decreased has realized the requirement that a pitch of fins is successively decreased.Rolling workbench with two guiding rails can carry cumulative volume and be 1400 * 810 * 3250 millimeters workpiece, and after the work of string sheet was finished, nimble release workbench and workpiece can carry out handling operation easily.

On the guide rail of main frame front and back position, the holding frame 5 of a pair of symmetry is arranged, it can move along guide rail flexibly, and has 22 grip blocks of interlock action, totally two groups, can regulate its height on demand.Hydraulic system is arranged at the top at main frame, and all hydraulic control components are installed on the oil-distributing plate, and system pressure is indicated by Pressure gauge.Electric system mainly independently formed by one by electric box and host computer control cabinet.
