Abstract

PURPOSE:To provide a frame of a press machine which takes advantage of the priority in terms of good workability and cost inherent to a C-frame press machine and has both of suppressability of deformation of the frame by working load and stability of the positional accuracy of the slide inherent to a straight side press. CONSTITUTION:A front plate 2 having a mounting hole 9A for a bearing member for supporting a crank shaft to vertically move a slide 6 and a hole 9B to permit carrying in and out of metal molds having the same plane as the rear surface of a bolster 8 fixed to a bed 7 as the rear edge are arranged on the front surface of the frame 1. A left side face plate 3 and right side face plate 4 having a C shape are fixed to the right and left of the rear surface of the font plates 2. A driving section 10, a slide guiding section 11 and the bed 7 are installed, by which the frame 1 of the straight side press machine is integrally formed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame of a straight side press machine for integrally forming a bed, a column and a crown.

[0002]

2. Description of the Related Art Straight side press machines are classified into an integral structural type in which a bed, a column and a crown are integrated, and an assembled structural type in which the bed, the column and the crown are divided and fastened with tie rods. When the work load during pressing is applied, the elongation of the frame acts only in the vertical direction, and there is little center misalignment between the upper mold and the lower mold, so precision machining or processing that requires a large work load is possible. It has an appropriate structure for the press machine in charge.

However, in order to reduce the vibration and noise generated during the press work and to improve the accuracy of the press-worked parts, the work is more difficult than the C-frame press machine in which the vertical deformation and opening of the frame are required to be small. There is something lacking in good quality and price advantage.

[0004]

[Problems to be Solved by the Invention] By utilizing the good workability and price advantage of the C frame press machine, and suppressing the deformation of the frame due to the work load of the straight side press machine during the press working. Provide a frame of a press machine having stability of slide position accuracy.

[0005]

A frame of a straight side press machine having both advantages of a straight side press machine and a C frame press machine is formed.

On the front surface of the frame, a mounting hole for a bearing member for supporting a crank shaft for vertically moving a slide via a connecting rod and a lower surface of a bolster fixed to a bed for receiving a working load during press working are provided. A front plate having a hole for allowing the mold to be carried in and out, which serves as a lower edge, is arranged, and side plates having a C-shape are fixed to the left and right rear surfaces of the front plate, and a drive unit is provided between the left and right side plates. The slide guide part and the bed are provided to integrally form the frame of the straight side press machine.

[0007]

[Function] A mounting hole for the crankshaft bearing member on the front surface of the frame, and a hole for loading and unloading a die whose lower edge is the same surface as the lower surface of the bolster fixed to the bed for receiving the work load during pressing. A front plate having a front plate, and left and right side plates having a C shape are fixed to the left and right rear surfaces of the front plate, and a drive unit, a slide guide unit, and a bed are provided between the left and right side platers. By forming the frame structure of the straight side press machine integrally formed, the frame deformation of the press machine due to the work load during press working is suppressed, and the frame of the press machine with stable slide position accuracy and superior workability and price is formed. .

[0008]

1 and 2 show an embodiment of the present invention.
Slide 6 on the front of frame 1 via connecting rod 5.
A mounting hole 9A for a bearing member for supporting a crank shaft (not shown) for vertically moving the shaft and a lower surface of the bolster 8 fixed to the bed 7 for receiving a work load during press working are the lower edges. A front plate 2 having a hole 9B through which a mold can be carried in and out is arranged, and a left side plate 3 and a right side plate 4 each having a C-shape are formed on the left and right rear surfaces of the front plate 2.
The left and right side plates (3, 4)
A drive unit 10, a slide guide unit 11 and a bed 7 are provided between them to integrally form the frame 1 of the straight side press machine.

[0009]

EFFECTS OF THE INVENTION By utilizing the good workability and price advantage of the C-frame press machine, and suppressing the deformation of the frame due to the working load of the straight side press machine at the time of press working, and the slide It is possible to provide a frame for a press machine that also has stable positional accuracy.
