Description

Press Brake stopper 4 position auto backgauge}

The present invention relates to a stopper four-axis automatic control device of the bending machine that can be produced precisely and quickly without regard to the size and shape of the product to be folded as a stopper four-axis automatic control device for the bending machine.

In general, the upper mold 104 and the lower mold 103 of the bending machine is engaged by making the bending shape of the material 105 due to the press and adjust the dimensions by using a mechanism called a stopper according to the dimensions to be bent.

The stopper's position control device is manual and automatic, and there is a big difference in production quantity and quality depending on the skill of the producer.

Even if there is no stopper position control device or simple automatic position control device, it is not accurate in its structure, or it is only simple, forward and backward or up and down movement. Can be.

Therefore, the operator's hand often enters the bending machine to control the dimension, which may cause a safety accident.

In addition, if other work is to be done in the middle of the work, the trouble of resetting the control device is generated, and the loss of time is large, which also affects the price of the product.

As mentioned above, according to the overall sheet metal industry, small quantity production of various kinds is more accurate than the existing position control devices, and the production of various precision products and the technical skills of technicians are leveled through free and quick accurate position control such as front, rear, top, bottom, left and right. It is also to help workers to prevent difficulties in their work and to prevent safety accidents occurring in manual work.

In order to achieve the above contents, the present invention device can be installed in the lower mold base 101 of the bending machine and its configuration is as follows.

Front and rear assembly 1 and 2 (1, 2), vertical axis assembly (3), vertical axis guide assembly (3 '), L guide bar (22) for feeding the stopper bundle (4, 5), pulley bracket (24), the motor pulley bracket (27), etc., the stopper bundle (4, 5) is provided with a front and rear fine adjustment device 30 in each stopper (31, 31 ').

1 is a plan view of the present invention to be installed in the lower mold base 101 of the bending machine using the fixing plate bolt 100 of the apparatus.

The forward and reverse assemblies 1 and 2 (1, 2) are assembled to the housing 13 with ball screws 11, 11 'and guide shafts 12, 12' to move linearly and forward and backward pulleys 7 and 8 The forward timing belt 6 is connected in parallel to connect the forward and backward motor pulley 9 and the forward and backward motor belt 10 of FIG. 3.

Forward and backward control of the upper assembly through the forward and backward servo motor (40).

In addition, the distance between the shafts of the forward and backward assemblies 1 and 2 (1, 2) on the side of the base 101 where this equipment is installed, and the distance between the shafts on the side to which the forward and backward timing belts 6 are connected, can be used for the change of temperature and time or physical change. Install and fix the fixing bar 102 to minimize.

According to the length of the forward and backward timing belts 6 of various distances, the interaxial distance between the forward and backward assemblies 1 and 2 (1, 2) can be adjusted.

The up and down motion is to operate the LM guide bar 22 up and down and consist of a TI screw 19 at the center and guide shafts 20 and 20 'at the right and a vertical LM guide 21 and 21' at the left and right. ) Vertically adjustable up and down by only the elem guide bar (22) by the vertical elm guide (21, 21 ') installed so that the inclination of both ends of the horizontal is vertical, precise vertical movement up and down.

The vertical axis timing belt 18 and the vertical axis pulley 17 of FIGS. 3 and 4 are connected to the vertical axis servomotor 41 to control the vertical position. At this time, the right angle between the forward and backward assembly 1 and 2 (1, 2) and the vertical axis assembly (3) of Figure 3 or 4 should be ensured when the vertical movement of the bending blade (103) according to the height change of the stopper 31 ) And the stopper 31 can be made constant.

Fig. 5 is a detailed view of the interior assembled inside the forward reverse assembly 1 and 2 (1, 2), which can ensure this.

The housing 13 is connected to the guide shafts 12 and 12 'ball screws 11 and 11' and linearly moves forward or backward by the direction of rotation of the ball screws 11 and 11 '. The shaft connecting guide bars 15 of the upper and lower shaft assemblies 3 are assembled with each other so that the entire upper assembly assembled on the housing connecting block 13 moves forward and backward.

Therefore, the two holes 13 assembled in the interior of the forward and backward assemblies 1 and 2 (1, 2) are machined with precision holes 107 on the left and right sides, respectively, and the precision holes 107 on the housing connecting block 15. ) By assembling the precision pin 106 by inserting it into the hole, and fixing the upper assembly connecting guide bar 15 thereon to ensure the vertical movement of the entire upper part with respect to the front and rear straight lines.

Individual left and right position transfer of the stopper bundles 4 and 5 consists of open-end timing belts 25 and 26 and the LM guide 23. The LM guide 23 is fixed to the front surface of the LM guide bar 22 horizontally. And put the stopper bundles (4, 5) to the LM guide (23).

Install the pulley bracket (24) and the motor pulley bracket (27) with two stages up and down at the upper ends of the LM guide bar (22) and walk open side timing belts (25, 26) in two stages side by side. When the belt connecting blocks 28 and 29 and the open end timing belts 1 and 2 (25 and 26) are connected to each other, the stopper bundles 1 and 2 (4, 5) is separately controlled from side to side according to the guide guide (LM) guide (23).

6 is a control device used when the material does not touch the two stoppers (31, 31 ') in a straight line and the layer is layered to make a female screw to the M block 34 and fine control device (30) ) Is a type of fitting by making a thin male screw and the head of the fine adjustment device (30) is inserted into the groove of the stopper adjustment bundle (32), when tightening or loosening the fine adjustment device (30), the stopper adjustment bundle (32) moves backwards and forwards. The stopper is adjusted.

The front of the head of the micro-adjustment device 30 to make a groove to be adjusted by using a screwdriver.

As described above, the two reverse stoppers 4 and 5 are placed on the horizontal and horizontal L guides 23 so that the forward and backward assemblies 1 and 2 (1 and 2) and the vertical axis assembly 3 are precisely perpendicular to each other. Since they can be located at each position, the product can be controlled at various positions regardless of the width, narrowness, and high / low refraction of the product or material having various stages of refraction, thereby enabling accurate and convenient operation.

In addition, when working with other products during use, it is immediately dealt with, and even when the contact surfaces of the stoppers 31 and 31 'are layered, the stoppers 1 and 2 (31 and 31') are fine-adjusted back and forth, respectively. Not only does it improve productivity, but also the stoppers (31,31 ') are controlled back and forth, height, left and right, etc.
