TH6672B - Pipe cutter for forming into a bend pipe. - Google Patents

Abstract

Tube benders for forming bent tubes, including structures made up of a base frame that can rotate in one plane in the opposite direction. The movable structure is made up of a number of forming rollers which are positioned to move in an up and down direction at the bending position. And the clamping device is made up of a separate telescopic movable handle with a forming roller in each bending step. The machine of this invention has a simple and cheap trigger press that can be operated easily. And it also improves workability because a number of pipes can be bent at the same time. The production capacity is therefore improved to achieve a particularly large quantity, the price of the product is reduced.

Claims (6)

1. A pipe cutter that consists of A base frame to support the pipe to be bent and installed. For an angular movement around an axis perpendicular to the base frame during a predetermined bend position, a number of forming rollers will be retracted from the operating position above the base frame. And a bend device that is synchronized with the subsequent forming rollers to bend the pipe. While the base frame from one bend position to the next 2. The machine according to claim 1, where the scaffold is horizontal and includes the supporting parts supported on a vertical support axis, positioned at the center of the base frame so that the base frame moves. Can be angular in the opposite direction around the vertical axis through the center 3. The machine according to claim 1 or 2, where the base frame consists of a support beam that is positioned across the base frame and supported by the forming rollers. Spaced from each other To comply with the required distance between the bends to be made in the pipe. 4. Device according to one of the previous claims Where the forming roller extends through the platen and retracts to a lower position than the tubular support surface of the platform by a device connected to the lower end of the forming roller. 5. Device according to one of the previous claims Where the bend device consists of a trajectory that includes a detachable clamping rod with a subsequent forming roller in the plane and the bend for relative angular motion and between the At its end there is a pressure roller that works together with the forming rollers to bend the pipe. 6. The machine for bending the pipe to bend back and forth consists of a support axis, the support parts are placed on the support axis. The base frame is supported in its center, up the supports so that it rotates around the axis through the center in the opposite direction in the horizontal plane. The distance between the adjacent bends according to the width that will be made of the pipe. A number of forming rollers can extend through the support beam and can move up or down to a position under the top of the support beam. A number of devices are connected to the bottom position of the forming roller and operate to move the forming roller up and down. The clamping device, including a chuck with a core at one end, is held separately in the hole. The axial is made in the forming rollers. In order to achieve angular motion of the handle in relation to the forming ball And the pressure roller is installed in the middle between the ends of the rod.
