Abstract

PURPOSE:To work exactly a work having a circular section to a prescribed shape in the stage of working the same in two working positions by rotating the work in the 1st working position at a prescribed angle by a magnet and transferring the same to the 2nd working position. CONSTITUTION:A transfer bar 1 which is held lowered is moved by a distance (l) in a left direction to move a receiving base 2C by a displacement (x) from the 1st working position B to the position on the right side, then the bar 1 is moved upward. A pipe P worked in the position B contacts the slope S in a V- groove 3 of the base 2C and falls along the slope S. The pipe P rolls without slipping on the slope S by receiving the magnetic force of the magnet 7 in the base 2C and rotates by the prescribed angle corresponding to the displacement (x) until it arrives at the bottom of the groove 3. The bar 1 moves by the distance (l) in a right direction in this state and the base 2C arrives at the 2nd working position C. The bar 1 is lowered here and the pipe P is subjected to prescribed working in the 2nd working position.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is based on a lift-and-carry system in which a workpiece is transported to a predetermined pressurized position by unloading and horizontally moving a transfer bar. This relates to a transfer device, and includes a single rotation mechanism for setting a workpiece having a circular cross section in a predetermined posture (+iii).

It's a lift-an-i-carry type transfer device.
1. Receiving shop that supports the work on the transformer tour bar.
After the transfer bar is moved horizontally by a predetermined distance while supporting the workpiece, the transfer bar is lowered and the workpiece is set on the pressurization unit 1, and the workpiece is pressurized. In the meantime, move the transformer tour bar back one step, then I. Lance 7-7-bar*--l:
Then, the machined workpiece is picked up by the receiver and the workpiece is transferred to the next processing position. Moreover, using the Una Transfer Device,
When stamping a workpiece having a circular cross section, such as a pipe, in multiple steps, the workpiece must be set in a predetermined posture in each step.

In this case, if sufficient +lIt &f +L is applied to the soak in the previous step, it is possible to use the bending and set it in a predetermined posture with a simple guide.
When working with straight pipes, or 4. workpieces with shallow bending angles that are close to straight pipes, it is difficult to maintain the prescribed posture. f11. It is.

Therefore, conventionally, when machining such a straight pipe or a workpiece that is close to a straight pipe, a special work rotation device was installed, or the process of pressurizing was performed first. It was necessary to consider the placement of each processing machine so that the However, providing such a special work rotation device increases equipment costs,
Not only does the required amount of gas become larger, but the number of waste steps increases. 1-There is a page ;)'. However, I am still having trouble assembling ``L'' for efficient machining, as constraints are imposed on the arrangement of the ``two'' configurations.

The present invention &: 1. This was made in view of the above circumstances, and the purpose of this invention is to achieve the following: [When a workpiece with a circular cross section is picked up, the t-hur of -4 is automatically carried out.] Another object of the present invention is to construct a one-lance tour device that rotates through a constant angle of 1e. 1. This purpose is to configure the present invention.
・The E-J spacer support that is installed on the -
Jj, and the receiver is equipped with a magnet that has enough magnetic force to cause the workpiece to roll down along the slope of the V-shaped groove without twisting. This is achieved by placing the workpiece in contact with the slope of the V-shaped groove at a predetermined position during the upper layer.

An embodiment of the present invention will be described below with reference to the drawings.

Figures 1 and 2 show the main parts of the I-transfer device, which is used to perform multiple steps of stamping using a press machine. This shows a state in which 2-if-0 has been transferred to a predetermined processing position. As shown in the figure, two parallel tow/sferno (-1, 1, Q ma, 1st machining position ■

Next, the operation of the above embodiment will be explained according to its working procedure.

First, the transfer par 1 is horizontally moved by a distance t to the left in FIG. 1.2. Then, the receiver base 2B reaches the loading position shown by the imaginary line in the figure. Here, the receiver loads the pipe P to be processed onto the stand 2B. Next, transfer par 1 is moved rightward in the figure by a distance t. As a result, the receiver table 2B reaches the first processing position B, so lower the transformer holder 1 and transfer the ξ-beam P to the bending die 4''2.3. In this state, operate the Zoretsuki (not shown).

Next, the transfer par 1 is moved leftward by a distance t while being fully lowered. Then, the pedestal 2B reaches the loading position A, and the pedestal 2C reaches a position on the right side of the first machining station B by a displacement position X. In this state, when the transfer paris is raised, it is supported on the bending mold 4 (as shown in Fig. It comes into contact with the slope S of the groove 3. When the transformer tour bar 1 is further raised, the guide P is relatively lowered to the surface S. At this time, the guide P is lowered relative to the surface S.
