Description
Technical field
The invention discloses a kind of welding machine tool of double-layer plastic door and window, be specially and a kind ofly realize the seamed double-deck door and window welding machine tool automatically changed with seamless welding and method.
Background technology
At present, in the welding procedure of plastic door-window, have two kinds of Type of Welding, one is seamless welding form, and another kind is seamed Type of Welding, seamless welding for the welding of mainly colored door and window, have seam welding for be the welding of common door and window.Some producers are in order to enhance productivity, market there are some welding heads for the double-layer plastic door and window of seamless welding, or for there being the welding head of double-layer plastic door and window of seam welding, but these devices are mostly only for a kind of Type of Welding, the automatic conversion of seam welding and seamless welding cannot be realized, if manufacturer thinks to weld colored door and window and common door and window simultaneously, just must purchase two bonding machines, cause cost just higher, and production efficiency is lower.
The patent No. of applying in Jinan Dejia Machine Co., Ltd is disclose a kind of double-layer plastic door-window welding machine head in the patent of [201120041301.0], this patent is mainly in order to solve " when with double-deck holder; upper strata fixture will with the upper plane of lower profile for datum level; the difference of section bar height itself can cause the flatness of upper strata window frame bad like this, affects end product quality.And the elastic force by spring between double-deck fixture every layer flicks, be not easy to control, operating very inconvenient " this technical problem proposes a set of double-layer plastic door-window welding machine head, but this head still cannot realize the automatic conversion of seam welding and seamless welding in use.
Summary of the invention
The present invention cannot realize the problem of the automatic conversion of seam welding and seamless welder in order to solve double-layer plastic door-window welding machine head, propose a kind ofly to realize the seamed double-deck door and window welding machine tool automatically changed with seamless welding.
The technical solution used in the present invention is as follows:
Realize the seamed double-deck door and window welding machine tool automatically changed with seamless welding, comprise a support, described support is provided with left frame and right frame, described left frame is fixed on the left end of support, right frame horizontally slips back and forth along support under the driving of drive unit, a lower-left head is installed in one end of described left frame, the other end installs upper left head, a bottom right head is installed in one end of right frame, the other end installs a upper right head, and described upper left head, upper right head under the driving of drive unit along lower-left head, direction, head place, bottom right slidably reciprocates, the structure for conveying for transmitting section bar is provided with in the inner side of described left frame, right frame, also be provided with a switch board in the side of support, described switch board is provided with a guidance panel, realizes the operation to whole lathe.
Described lower-left head, upper left head, bottom right head and upper right head comprise machine head base separately and are located at compressing structure, heating arrangement and the location structure above machine head base, described compressing structure comprises vertically disposed upper and lower two parts, wherein every part includes and is vertically disposed on upper pressing tongs on supporting seat and lower pressing tongs, lower pressing tongs is fixed on supporting seat, upper pressing tongs moves up and down under the effect of compression cylinder, and described upper pressing tongs and lower pressing tongs include a front clamper and rear pressing tongs; Described location structure and heating arrangements are arranged in location heating transformational structure, seamed and the seamless welding that detent mechanism realizes upper and lower two-layer door and window by the pore size changed between front clamper and rear pressing tongs under the driving of drive unit is simultaneously changed automatically, described heating arrangement realizes the heating of upper and lower two-layer door and window under the driving of drive unit simultaneously, and automatically changes with the seamed seamless welding of detent mechanism the automatic conversion realizing seamed seamless heating.
Described heating arrangement comprises heating plate, is provided with upper and lower holding piece on hot plate, and described heating plate is by connecting plate and driving cylinders, and described connecting plate moves around along a pair slide rail pair.
Described detent mechanism comprises a upper location-plate and a lower location-plate, described upper location-plate and lower location-plate, by same connecting plate and same cylinders, are located while upper location-plate and lower location-plate realize upper and lower two-layer clamping structure under the driving of same cylinder simultaneously.
Described upper location-plate, the bottom of lower location-plate are provided with a second order boss separately, and one of them boss is used for being positioned with seam welding; One of them boss is for locating seamless welding.
Described location heating transformational structure comprises heating positioning sliding block seat, described detent mechanism and heating arrangement are arranged on heating positioning sliding block seat, described heating positioning sliding block seat is under the driving of cylinder switching, move up and down, to realize the clamping of the diverse location of detent mechanism and heating arrangements, and then realize the conversion of seamed seamless two kinds of welding manners; The bottom of described heating positioning sliding block seat is also provided with the transposition cylinder driving detent mechanism and heating arrangement transposition.

A. upper and lower location-plate realizes the feeding in forward and backward pressing tongs under the driving of drive unit, and the forward and backward pressing tongs of upper and lower compressing structure closes up, and clamps location-plate;
B. conveyer belt translation cylinder is retracted, and conveying mechanism is close to frame;
C. right frame moves to desired position along support under the driving of drive unit;
Step 5. places section bar and below section bar above;
Step 6. presses operation button, upper left head and upper right head under the driving of drive unit along gantry motion to desired position;
Step 7. places left side section bar and right side section bar,
Step 8. presses operation button, and the upper pressing tongs of upper and lower compressing structure falls compression section bar;
The forward and backward pressing tongs of the upper and lower compressing structure of step 9. is return, and jaw is dehisced, and location-plate exits under the driving of drive unit;
Step 10. heating plate enters under drive unit, and the forward and backward pressing tongs feeding of upper and lower compressing structure is closed up, and heats section bar;
After the heating of step 11. section bar, the forward and backward pressing tongs of upper and lower compressing structure opens to be return, and heating plate exits;
The forward and backward pressing tongs of the upper and lower compressing structure of step 12. again feeding closes up, and section bar docking is merged;
The upper and lower pressing tongs of step 13. lifts, and forward and backward pressing tongs exits, and liftout cylinder stretches out simultaneously, and by section bar top from lower pressing tongs, conveyer belt movable cylinder stretches out, and conveyer belt is away from frame, and right frame moves to right; Charging cylinder stretches out, and section bar is pushed away head;
Step 14. lower floor liftout cylinder is retracted, and lower profile is fallen on conveyer belt, is transferred out by the section bar welded by conveying mechanism;
Step 15. upper strata retainer cylinder stretches out, and upper aluminum profiles is fallen on conveyer belt, is transferred out by the section bar welded by conveying mechanism.
