Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a transfer table transfer device for a Thompson press,

The present invention relates to a transfer table transfer apparatus for a Thomson press for transferring a transfer table on which a lower mold is placed in a Thomson press for model cutting a product, and more particularly, to a transfer table transfer apparatus for transferring a timing belt Or chains) are disposed on the conveying table, and the timing belt and the conveying table are connected by clamps.

"Thompson Press" is introduced in Korean Patent No. 10-0441670 (registered on July 15, 2004).

The Thompson press is fixed to an upper mold, a work table disposed at a lower portion of the upper mold can perform a vertical stroke movement, and a transfer table is mounted on the work table so that the transfer table can be moved back and forth along guide rails of the work table A lower mold is mounted on the transfer table, a sheet material for model cutting is placed on the lower mold, and a shock absorber is mounted on a lower surface of the transfer table which can be moved back and forth by a hydraulic cylinder.

However, in the Thompson press, the transfer table is transferred by the hydraulic cylinder, so that the transfer table splashes, and additional components such as a stopper and a shock absorber are required to prevent the transfer table.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an apparatus and a method for clamping a timing belt and a transfer table by clamping a timing belt (or a chain) on a pair of arms connected to a press workbench, When the conveying table is placed on the upper surface of the work table, the space between the pair of arms forms an empty space, so that the operator can enter the space between the arms And to provide a transfer table transfer device for a Thomson press which is very useful in space utilization.

According to another aspect of the present invention, there is provided a transfer table transfer apparatus for a Thompson press, comprising a pair of arms connected to a press workbench, a timing belt disposed on each of the pair of arms, A motor, a speed reducer, and a power transmission shaft are disposed on one side of the press workbench, the power of the motor is transmitted to the speed reducer, the output of the speed reducer is supplied to the power transmission shaft through the belt A drive pulley of a timing belt is mounted on an end of the power transmitting shaft, respectively, and a clamp is mounted on each timing belt, and each clamp is mounted on a lower surface of the transfer table.

Further, a transfer table transfer apparatus for Thompson press according to the present invention is characterized in that when the transfer table is disposed on the upper side of the arm, the clamp is disposed close to the follower pulley of the timing belt, and the transfer table is disposed on the upper surface of the press work table A clamp is arranged close to the drive pulley of the timing belt and a detection sensor is arranged close to the driven pulley to determine a first stop position at which the transfer table is stopped at the top of the arm by the detection sensor, The second stop position stopped on the upper surface of the work table is determined by calculation of the feed distance and the feed distance is stored in the control unit and the feed table of the first stop position is moved by the feed distance to reach the second stop position .

Another example of the transfer table transfer apparatus for Thompson press according to the present invention is a transfer table transfer apparatus for a Thompson press, in which a pair of arms are connected to a press workbench, a chain is arranged on each of the pair of arms and a chain is driven by a drive sprocket and a follower sprocket A motor, a speed reducer, and a power transmission shaft are disposed on one side of the press workbench so that the power of the motor is transmitted to the speed reducer, the output of the speed reducer is supplied to the power transmission shaft through the belt, And a clamp is mounted on each of the timing belts, and each of the clamps is mounted on a lower surface of the transfer table.

Thus, the conveying table conveying device for Thompson press according to the present invention is capable of withstanding the impact of the timing belt and its components, long component life, high conveying table conveying speed, low noise, The space between the pair of arms forms an empty space so that the operator can enter the space between the arms to take out the product, and the space utilization is very useful.

1 is a side view of a Thomson press including a transfer table transfer apparatus according to the present invention in which a transfer table is disposed at the top of the arm.
FIG. 2 is a side view of a transfer table transfer apparatus for a Thomson press according to the present invention, in which a transfer table is transferred to an upper portion of a press work table.
3 is a plan view showing a transfer table transfer apparatus for a Thomson press according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

1 to 3, a transfer table transfer apparatus for a Thomson press according to the present invention is characterized in that a pair of arms 20, 25 are connected to a press work table 10 and a pair of arms 20, The timing belt 30 is driven by the drive pulley 31 and the driven pulley 32 mounted on the arm 20 and the one side 11 of the press workbench 10 is driven, The power of the motor 41 is transmitted to the speed reducer 42 and the output of the speed reducer 42 is transmitted through the belt 44 to the power And the driving pulley 31 of the timing belt 30 is mounted on the end of the power transmission shaft 43 and the clamp 33 is mounted on each of the timing belts 30 , And each of the clamps 33 is mounted on the lower surface of the transfer table 50.

1, when the transfer table 50 is disposed on the upper portion of the arms 20 and 25, the clamp 33 is positioned between the timing belt 30 The clamp 33 is disposed on the timing belt (not shown) when the transfer table 50 is disposed on the upper surface 12 of the press workbench 10, as shown in FIG. 2, S2 are arranged close to the driven pulley 32 so that the transfer table 50 is moved by the sensors S1, S2 to the arms (The position of the transfer table shown in Fig. 1) to be stopped at the upper part of the work table 20, 25 is determined and the second stop position The position of the illustrated transfer table) is determined by calculation of the transfer distance L1, the transfer distance L1 is stored in the control unit (not shown) The transfer table 50 at the first stop position shown in FIG. 1 is shifted by the transfer distance L1 to reach the second stop position shown in FIG.

The power transmission of the motor 41 is supplied to the speed reducer 42 and the output of the speed reducer 42 is transmitted to the power transmission shaft 43 through the belt 44. [ The drive pulley 31 is mounted on both ends of the power transmission shaft 43 and the drive pulley 31 is rotated in the forward or reverse direction by the power transmission shaft 43 so that the drive pulley 31 The transfer table 50 is transferred to the second stop position of the upper surface of the press work table 10 at the first stop position of the arms 20 and 25 shown in Fig. 2 by the timing belt 30 interlocked with the transfer table 50, And is transported from the second rest position to the first rest position.

When the upper mold and the lower mold are combined with each other, the timing belt and the constituent elements of the transfer belt are supported by the impact applied to the transfer table due to the flexibility of the timing belt, When the conveying table is placed on the upper surface of the press workbench, the space between the pair of arms forms an empty space, so that the operator can enter the space between the arms It is possible to take out the product, and there is an advantage that the space utilization is very useful.

Also, the transfer table transfer device for Thompson press according to the present invention can replace the timing belt and the pulley with a chain and a sprocket.
