Description

A kind of taping machine

Technical field

The utility model relates to a kind of equipment for wrapping that is applicable to the automobile opening tool.

Background technology

The inside and outside plate assembling that wrapping process generally is used for the automobile opening tool connects; With cut down output living upper overturning or after down flange flattens of part upper punch, the inside and outside plate of part is linked together by bending.Before the bound edge on outside plate coating structure glue, guarantee the mechanical strength of assembling back component, this glue does not produce polymerisation in the workshop that is welded, and only guarantees the stability of the physical dimension of welding assembling.

The implementation of wrapping process mainly contains: (1) pulls golden bound edge by hand; (2) mould+hand-held taping machine bound edge; (3) mechanical taping machine bound edge; (4) robot binding.Select which kind of wrapping process and equipment for use, be according to production lot, product type, kind what, decisions such as investment size and bound edge required precision.

Machinery taping machine bound edge is owing to its production efficiency height, and the bound edge quality is good, and labor strength is little, and equipment drops into moderate advantage and selected for use by numerous producers.At present the taping machine structure mainly contains 3 kinds of single rocking arm wedge cam structure, two rocking arm wedge cam structure and six bar linkage structures, and its structure diagram is seen Fig. 2, Fig. 3 and Fig. 4.

See Fig. 2, single rocking arm wedge cam structure course of work is: put well treat the bound edge workpiece after, it is descending that forcing press drives patrix, holding pad workpiece pressing, wedge 2-1 actuating cam 2-2 make jack knife 2-5 rotate around fixing point workpiece are converted into specified angle; Descending with the patrix continuation, contact wedge 2-1 inclined-plane with cam 2-2 and stop, through a transition region spring 2-3 jack knife 2-5 is retracted, get out of the way push type broach 2-7, push type broach 2-7 continues the descending bound edge action of finishing, and patrix returns, and mechanism resets and waits for next circulation.

See Fig. 3, two rocking arm wedge cam structures and single rocking arm wedge cam structure are similar, and the course of work is also basic identical.Different is to replace single rocker arm body with parallel 4 linkages.

See Fig. 4, the six bar linkage structure courses of work are: oil cylinder 4-1 releases piston rod 4-2, push type broach 4-3 clockwise rotates and promotes jack knife 4-5 by connecting rod 4-4 around a point and clockwise rotates around d point and workpiece is carried out pre-bound edge move, and finishes pre-bound edge when a, b, c point straight line; Along with the continuation of oil cylinder 4-1 is released, b point is crossed a, c line, and connecting rod 4-4 pulling jack knife 4-5 motion counterclockwise leaves workpiece, returns gradually, and push type broach 4-3 continues to move clockwise and presses to workpiece and finish bound edge.Oil cylinder 4-1 returns, the circulation of finishing the work.

More than 3 kinds of structures can both put in place by a bound edge, automaticity is also higher.But preceding two kinds of structures adopt forcing press to drive mould pressing bound edge, cost is with high investment big, and the volume of forcing press own is big, and homemade forcing press ground level size is generally more than 5m, bigger to the factory building restriction, the complex structure maintenance difficult also is difficult to the industry adjustment and part is carried automation.And six bar linkage structures hydraulic oil cylinder driving needs independently hydraulic control system, and control procedure is complicated, poor working environment, and the too high increase labor strength of push type broach 3 open positions, the separate design of jack knife and push type broach has increased the time of cost and debugging.

The utility model content

For solving the problems of the technologies described above, the utility model proposes a kind of taping machine with jack knife and push type broach integrated design, the utility model volume is little, input cost is cheap, debugging maintenance is convenient, has improved workman's working environment and labour intensity, has high popularizing value.

The utility model is achieved by the following technical solution:

A kind of taping machine, it is characterized in that: comprise first driving mechanism, be hinged with fork with the piston rod of first driving mechanism, one end of fork is a stiff end, and stiff end is an oscillation center, the stiff end that described piston rod stretching motion makes fork center on described fork is done oscillating motion, and relies on described first scotch and second scotch that fork is stopped swinging; The other end of described fork is a swinging end, one end and the described swinging end of rocking bar are hinged, and the other end of rocking bar is articulated on the connecting rod, and the upper end of described connecting rod is fixedly connected with bound edge and inserts, the lower end of connecting rod is articulated on the crank, and described crank is connected with second driving mechanism; Described bound edge is inserted and the workpiece mating surface is made up of pre-bound edge face and forming wrapping face.

The both sides of fork be provided with control fork hunting range on scotch and following scotch.

Described upward scotch and following scotch are between piston rod and fork hinged place and fork and rocking bar hinged place.

Described connecting rod is vertical mutually with the bound edge die of carrying workpiece.

Described first driving mechanism is a cylinder.

Described second driving mechanism is a motor.

Advantage of the present utility model is:

1, since the utility model adopt " comprise first driving mechanism; be hinged with fork; an end of fork is a stiff end; and stiff end is an oscillation center; the stiff end that described piston rod stretching motion makes fork center on described fork is done oscillating motion, and relies on described first scotch and second scotch that fork is stopped swinging with the piston rod of first driving mechanism; The other end of described fork is a swinging end, one end and the described swinging end of rocking bar are hinged, and the other end of rocking bar is articulated on the connecting rod, and the upper end of described connecting rod is fixedly connected with bound edge and inserts, the lower end of connecting rod is articulated on the crank, and described crank is connected with second driving mechanism; Described bound edge is inserted and the workpiece mating surface is made up of pre-bound edge face and forming wrapping face." such technical scheme compared with prior art; it is integrated and insert alternative with bound edge to have jack knife and push type broach now; crank and rocker mechanism and swing-bar mechanism have constituted seven-bar mechanism jointly; realized that by fork and rocking bar the pre-bound edge of workpiece and the bound edge insert site of forming wrapping switch; thus the volume of complete machine is reduced; and input cost reduces, make debugging maintenance convenient, workman's working environment and labour intensity have been improved, match with other production line beats in the workshop, realize synchronization production, had high popularizing value.

2, because the utility model has adopted last scotch and the such technical scheme of following scotch, make the hunting range of fork precisely controlled, further improve thereby make pre-flanging action finish quality, and can realize the precompressed angle of workpiece and the adjustment of position according to the position of scotch.

3, because first driving mechanism that the utility model adopts is a cylinder, and second driving mechanism is a motor, these driving arrangements all are equipment relatively more commonly used in the workshop, and the cost cost is lower, and control mode is also simpler.
