Description

Three roller symmetric plate bending machines volume cone servicing unit

Technical field

The utility model relates to veneer reeling machine, relates in particular to three roller symmetric plate bending machine rolling wimble devices.

Background technology

Conventional three roller symmetric plate bending machines can roll cylindrical member, and the angular speed that rotated at the member two ends when veneer reeling machine was worked under the conventional situation is identical, and the linear velocity at two ends is also identical, fan body sheet material can't be rolled into taper.And fan-shaped sheet material to be rolled into centrum, and must satisfy following requirement when member rotates: the large end of member and small end should rotate with identical angular speed curling, and the linear velocity at two ends will be directly proportional with its diameter, and namely large end line speed is large, and the small end linear velocity is little.

Summary of the invention

The utility model is intended to address the aforementioned drawbacks, and a kind of three roller symmetric plate bending machines volume cone servicing unit is provided.The cone-shaped component circular arc that the utility model rolls out is level and smooth, and quality is good, and efficient is high, saves time, and reduces expenses.

For addressing the above problem, a kind of three roller symmetric plate bending machines volume is bored servicing unit, and it comprises:

A U-shaped bearing, its biside plate are the identical fanning strip of shape,

A round steel bar, it inserts between the biside plate of described U-shaped bearing, and its termination and side plate are pivotally connected;

A spacer pin, it is horizontally through two side plates of U-shaped bearing and round steel bar, and head end is fixed with pin.

Described three roller symmetric plate bending machines volume cone servicing unit, a base angle of the side plate of described U-shaped bearing is the right angle, and another is acute angle, and right limit, base is arc.

The utility model has solved three roller symmetric plate bending machines effectively can only roll cylinder component, can't roll the problem of vertebral members, with regard to existence conditions, on the basis of three rolls plate bending machine, rolled up the cone servicing unit, success roll out the level and smooth cone member of circular arc.Avoided buying the equipment that rolls specially the cone member, economized on the use of funds; Roll the cone member and reach the design drawing requirement, circular arc is level and smooth, reliable in quality; This apparatus structure is simple, easy to make, processing ease, applicability are strong, obtains the favorable comment of shop floor worker; This device production efficiency is high, and economic benefit is obvious, and application prospect is extensive.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is the utility model schematic diagram;

Fig. 2 is the A-A cutaway view of Fig. 1.

The specific embodiment

See also Fig. 1, a kind of three roller symmetric plate bending machines volume cone servicing unit, it comprises:

A U-shaped bearing 2, its biside plate are the identical fanning strip of shape,

A round steel bar 1, it inserts between the biside plate of described U-shaped bearing, and its termination is connected with side plate pivot 5;

A spacer pin 3, it is horizontally through 2 two side plates of U-shaped bearing and round steel bar 1, and head end is fixing with pin 4.

Described three roller symmetric plate bending machines volume cone servicing unit, a base angle of the side plate of described U-shaped bearing is the right angle, and another is acute angle, and right limit, base is arc.

After stressed analysis, design this device and comprise one on Φ 120mm round steel bar, one of Φ 70mm alignment pin, one of Φ 70mm rotating shaft, one of the little alignment pin of Φ 10mm, base sheet metal thickness 50mm is Q235B with the upper member material.Utilize this device to roll the concrete operations of cone member as follows:

1, will be align with the three rolls plate bending machine feed roller on the limit by the fan-shaped sheet material of figure paper size blanking, fan-shaped sheet material small arc-shaped one side contacts with the round steel bar of rolling wimble device always, lay put in place after, open three rolls plate bending machine;

2, originally fan-shaped sheet material two straight flange end portions are carried out pre-bending, integral body rolls again after reaching the design camber;

3, because the screens effect of round steel bar having been arranged, the large end of member and small end should be rotated with identical angular speed curling, and the linear velocity at two ends is directly proportional with its diameter, treats a curling week of member, after two straight flanges of sheet material contact, close three rolls plate bending machine;

4, locate with intermittent weld (every 10cm weldering 10cm) along two straight flanges, open again three rolls plate bending machine, slowly roll, until the member circular arc is level and smooth.

5, take off member, the butt weld weldering is full, and so far the cone member completes.

Claims (2)
