Abstract

The utility model discloses a forming mill of a brace slide block mechanism, which comprises a stander, a thrusting hydro cylinder, a thrusting trolley, a driving trolley, a motor reducer, a thrusting slide seat, a brace slide mechanism comprising the thrusting slide seat, a thrusting arm, a slide block and a rolling seat, a rolling wheel and a rolling axis. The rolling wheel is movably connected with the rolling seat through the rolling axis. Using the utility model can totally restrict the bending deflection of workpiece ventral shield, and eliminates the bad deflections of the wave-shaped bending of the workpiece in the longitudinal direction, etc., therefore the processing limitation of a common forming mill is conquered and the rate of finished products of the workpiece is improved.

Description

The slider-crank mechanism forming mill

Technical field:

The utility model relates to a kind of forming mill, and the slider-crank mechanism forming mill of undesirable deformation does not take place workpiece in especially a kind of roll extrusion process.

Background technology:

Forming mill is the equipment that is used for section bars such as I-steel, H shaped steel, channel-section steel are bent into arc-shaped workpiece.Existing forming mill is made up of frame, pushing oil cylinder, thrust roller, driving rolls, motor reducer, pushing slide and corresponding transmission mechanism, controlling organization, during work workpiece placed between thrust roller, the driving rolls with the pushing oil cylinder workpiece is bent after, starter motor, rotation driving rolls are rolled into arc with workpiece, workpiece easily produces the wing plate distortion in the roll extrusion process, abdomen the companion buckle, reach undesirable deformations such as longitudinal wave shape wave bending, cause workpiece not meet instructions for use.

Summary of the invention:

It is a kind of at the slider-crank mechanism forming mill that workpiece is carried out not taking place in the roll extrusion process undesirable deformation that the utility model provides, comparing with existing forming mill has increased slider-crank mechanism, when work, workpiece is positioned over upper and lower rolling between wheel, by upper and lower roll roll after wheel compresses the workpiece web curved, can limit workpiece web buckling distortion fully like this, and eliminate the undesirable deformations such as wave bending of workpiece on vertically, and just overcome the manufacturing deficiency of common forming mill, improve the workpiece yield rate.

The technical solution of the utility model is:

The utility model comprises frame, pushing oil cylinder, thrust roller, driving rolls, motor reducer, pushing slide, it is characterized in that: also comprise the slider-crank mechanism that constitutes by pushing slide and pushing-pressing arm, slide block, rolling seat, and roll wheel, roller bearing, roll wheel and flexibly connect through roller bearing and rolling seat.

The pushing-pressing arm of the utility model crank mechanism is movably connected in pushing slide the right and left through bolt, and slide block is arranged in the axis hole of pushing-pressing arm, also can slide in the chute of rolling seat.

The utility model rolls wheel and is contained on the roller bearing, rotates and slip with respect to roller bearing, and roller bearing is fixed on the rolling seat.

The utility model rolling seat is connected with frame by rotating shaft, can rotating shaft be that swing on the plane of frame in the axle center.

The utility model course of work is:

During work workpiece is positioned over upper and lower rolling between wheel, by upper and lower roll wheel the workpiece web compressed after, roll curved by the propelling of pushing oil cylinder.

Owing to increased slider-crank mechanism, it allows rolls wheel along with the propelling of pushing oil cylinder is swung with respect to frame, makes and rolls wheel vertical with the workpiece tangential direction all the time with the workpiece contact position, rolls wheel like this in the workpiece roll bending process and can reduce skimming wear with the workpiece web.

Advantage of the present utility model is: adopt the utility model can limit workpiece web buckling distortion fully, and eliminate the undesirable deformations such as waveform bending of workpiece on vertically, just overcome the manufacturing deficiency of common forming mill, improve the workpiece yield rate, and have and make simple, the low big advantage of effect of cost.

Description of drawings: Fig. 1 is that the utility model top plan view structural representation Fig. 2 is that mark among the top plan view structural representation figure that structural representation Fig. 3 is existing forming mill cuts open in the utility model right side office of looking: 1 is that frame 2 is that driving rolls 6 for motor reducer 7 for pushing slide 8 for pushing-pressing arm 9 be slide block 10 for rotating shaft 11 for rolling seat 12 for roll wheel 13 be roller bearing for thrust roller 4 for I-steel 5 for pushing oil cylinder 3

The specific embodiment:

The utility model comprises frame 1, pushing oil cylinder 2, thrust roller 3, driving rolls 5, motor reducer 6, pushing slide 7, it is characterized in that: also comprise the slider-crank mechanism that constitutes by pushing slide 7 and pushing-pressing arm 8, slide block 9, rolling seat 11, and roll wheel 12, roller bearing 13, roll wheel 12 and flexibly connect through roller bearing 13 and rolling seat 11.

The pushing-pressing arm 8 of the utility model crank mechanism is movably connected in pushing slide 7 the right and lefts through bolt, and slide block 9 is arranged in the axis hole of pushing-pressing arm 8, also can slide in the chute of rolling seat 11.

The utility model rolls wheel 12 and is contained on the roller bearing 13, rotates and slip with respect to roller bearing 13, and roller bearing 13 is fixed on the rolling seat 11.

The utility model rolling seat 11 flexibly connects by rotating shaft 10 and frame 1, can rotating shaft 10 swings on the plane of frame 1 for the axle center.
