Machining of straight-cylinder or curved busbar parts is encountered during machine manufacturing. In the prior art, the simple plate rolling such as straight cylinder is easy to realize, but the plate rolling of the round table-like part of the round table or the curved bus is rarely reported.

The special feature of the round-rolling of the plate of the round-table-shaped or curved bus-bar-like part is that the diameter of the cross-section circle along the axial direction is changed, the deformation of the plate is different, so that the rebound degree of the plate is different, the plate is deviated along the side with large deformation in the vertical direction, the round-rolling cannot be further performed, and the expected forming effect cannot be achieved. Aiming at the offset problem in the vertical direction, the traditional solution is to arrange a limiting mechanism on the upper and lower sides of the plate to forcibly fix, but the limiting mechanism has a plurality of problems such as larger size, heavy weight, high manufacturing cost, inconvenient assembly and disassembly of workers, low working efficiency and the like.

Disclosure of Invention

The utility model aims at solving the problem of plate rolling of the round-table-shaped or round-table-shaped part of the round table-shaped or round-shaped part and the defect of the traditional limiting mechanism by providing the round table-shaped die of the round table-shaped part of the plate round-shaped or round-shaped part of the round table-shaped, wherein the die adopts the portable dismounting limiting mechanism which can clamp the plate and limit the movement of the plate in the vertical direction due to inconsistent upper and lower deformation amounts so as to ensure the forming of the plate.

In order to achieve the above purpose, the curved bus piece rolling die provided by the utility model comprises a female die and a male die, wherein a certain distance is kept between the female die and the male die, a metal sheet part to be rolled stretches in, and the female die can rotate under the drive of a motor and drives the metal sheet part and the male die to rotate. The upper and lower surfaces of the female die are respectively provided with a rotating rod which extends outwards from the central part of the female die, and a connecting rod which is arranged in the vertical direction is connected with the end parts of the two rotating rods. The rotating rods are provided with key grooves, the sliding blocks can slide along the key grooves, and the clamping devices capable of limiting the metal plate parts to move in the vertical direction are connected with the sliding blocks.

In order to reduce friction between the surface of the female die and the rotating rod, pulleys are arranged on the rotating rod on the upper surface and the lower surface of the female die at positions close to the center of the female die.

The number of the male dies is odd, and the male dies are arranged in a straight line, wherein the distance between the male dies positioned in the middle position and the center of the female die is smaller than the distance between other male dies and the center of the female die.

When the rolling operation is carried out, the female die which rotates under the drive of the motor moves towards the middle male die to extrude the middle male die, so that the female die deviates from the straight line, and a folding angle is formed between the female die and the male dies and other male dies on two sides, so that the metal plate part between the female die and the male dies is bent.

Compared with the prior art, the utility model has the following advantages:

for the limit problem, the curved bus piece rolling die adopts the rod with the chute, which can rotate 360 degrees on the upper surface and the lower surface of the female die, the slide block capable of moving back and forth is arranged in the chute, and the clamping device for clamping the plate is arranged at the end part, so that the metal plate part can move randomly in the horizontal plane, and meanwhile, the metal plate part can be prevented from moving in the vertical direction.

The curved bus piece rolling die with the portable disassembly and assembly limiting mechanism has the advantages of being simple in structure, small in size, light in weight, convenient to disassemble and assemble, low in production cost and capable of improving working efficiency.

Detailed Description

The utility model will be further described in detail with reference to the drawings.

As shown in fig. 1-3, the utility model provides a curved bus piece rolling die with a portable dismounting and mounting limiting mechanism, which comprises a central female die 1 and a male die 2 positioned at one side of the female die, wherein a certain distance is kept between the female die and the male die for a metal plate to extend in. The upper and lower sides of die 1 set up dwang 3 respectively, and connecting rod 4 on the vertical direction connects upper and lower dwang, all opens the keyway on two dwang, and slider 5 can follow the keyway and slide, realizes the motion of sheet metal part in radial direction. The clamping device 6 is connected with the slide 5 in order to limit the movement of the sheet metal part in the vertical direction, and the pulley 7 is mounted on the rotating rod 3 near the centre of the die, which acts to reduce friction between the die surface and the rotating rod.

The metal plate part can move on the circumference through the connection of the rotating rod and the female die, and as described above, the sliding block is connected with the rotating rod through the key slot, so that the part moves in the radial direction, and the clamping device is connected with the sliding block to limit the part to move in the vertical direction.

The working process of the curved bus piece rolling die is as follows: in use, the metal sheet is placed in a die, clamped by the die cavity die 1 and the male die 2, and limited to move in the vertical direction by the clamping device 6. The number of the male dies 2 is generally 3, the male dies are in linear arrangement, the female dies 1 move to the middle male dies 2 for a proper distance, the middle male dies are extruded to deviate from the straight line, and form a folding angle with other male dies on two sides, so that the metal sheet material is bent, then the motor drives the female dies 1 to rotate, drives the metal sheet material parts and the male dies to rotate, the metal sheet material is bent section by section, and the curvature radius of the metal sheet material is gradually reduced by gradually increasing the left-moving distance between the female dies 1 and the middle male dies 2 until the metal sheet material is finally formed.

The rolling die has the main advantages that: firstly, the large-size limiting device used in the prior art is abandoned, and the rotating rod which is simple and convenient to disassemble and assemble is used for replacement, so that the same effect can be realized; and secondly, the manufacturing cost is low, the operation is convenient, and a reference is provided for the follow-up similar die.
