The present invention relates to a slide guide device for a press. Specifically, the present invention relates to a slide guide device for guiding a slide to have a large perturbation during press operation.

Conventionally, the press includes a slide. The copper alloy liner serves as the slide face. The press includes an iron gib disposed on a frame opposite the slide face. During operation, the liner and jib slide against each other to guide the slide along the frame.

The spacing between the liner and the opposing jib is approximately 5/100 mm. Typically, the lubricating oil smoothes the sliding surface. The lubricating oil forms an oil film between the liner and the jib to minimize friction and wear.

Unfortunately, eccentric forces often occur at the press. These eccentric forces force the liner and jib to form 'line contact'. Line contact occurs when the lubricating oil film is broken and thus direct sliding contact occurs. Direct line contact wears and squeezes the sliding surface and increases the mechanical resistance the press motor must overcome. If not repaired, the line contact causes motor failure and damage to expensive equipment.

In addition, the spacing necessary to hold the oil film is fatal for high precision purposes. In large high precision presses with eccentric loads, in particular, large slides maximize pressure with the lethal line contact generated. In the past, this fatal effect was partially mitigated through the use of "two-point" and "four-point" press designs.

"2-point" and "4-point" presses require expensive high precision designs. Production of precision parts is difficult, expensive and time consuming. Ultimately, no matter how accurate the design, the deep load will still cause line contact between the liner and the jib.

Applicant's previously filed Japanese Patent Application No. 2000-193782 partially overcomes this difficulty by using spherical blocks and jibs that slide and face each other along a liner with a V-shaped sliding surface. Unfortunately, the V-shaped alignment of the spherical blocks and jibs is difficult. Despite this design, the V-shaped face of the spherical block will ultimately require expensive repair costs and trouble-free maintenance due to contact damage during heavy loads.

It is an object of the present invention to provide a slide guide device for a press that overcomes the above problems and difficulties.

The first pair of liners 11 and 11 is fixed to the jib 5b opposite the slide 2b. The second pair of liners (not shown) are secured to the jib 6b in a similar manner. The liners 11 and 11 have a flat shape and are vertically attached along the jibs 5b and 6b.

Each jib 5b, 6b has two contact surfaces that run parallel along the slide 2b. Liner 11 is located on each contact surface along jibs 5b and 6b. The slider 2b has a contact surface corresponding to the contact surfaces on the jibs 5b and 6b. The contact surfaces on the jibs 5b and 6b and the slide 2b slide parallel to each other to allow easy and precise movement of the slide 2b.

In this embodiment, the spherical shoe pairs 7, 7 and 9, 9 are rotatably fitted inside the corresponding spherical hollow 18 on the slide 2b. The flat portions of the spherical shoes 7, 7 are in contact with the liner 11 on the jib 5b and slide freely. The flat portions of the spherical shoes 9 and 9 are in contact with the liner 11 on the jib 6b and slide freely. The spherical surfaces of the spherical shoes 7, 7 and 9, 9 rotate inside the hollow 18 so that the entire surface of each flat portion remains parallel to each liner 11.

After adjustment, the bolt 17 secures the wedge 12 and the jib 5b to the frame 1.

The contact surfaces on the jibs 5b and 6b correspond to the faces of the respective liner pairs 11 and 11. The angle alpha α is the angle between the contact surfaces (and of the liner 11). The angle alpha α is selected based on the state of the eccentric load during the press operation.

During operation, pressure (force) from the slide 2b is passed through each of the spherical shoes 7, 8, 9 and 10 to the contact surface of the liner 11.

The force acting on each contact surface can be analyzed based on the slope of the contact surface. The force can be decomposed into a limiting force along the left and right axes of the slide 2b and a limiting force along the front and back axes of the slide 2b. Thus, the slide 2b is limited along the front and rear left and right axes by the jibs 5b and 6b.

, 즉, 대략 1.7:1임을 나타낸다.In the present embodiment, the angle alpha α is approximately 120 degrees. In this embodiment, the eccentric load along the left and right axes of the slide 2b is greater than the eccentric load along the front and back axis. In other words, the projected area along the left and right sides of the guide face is larger than the projected area along the front and rear axes. If the angle alpha (α) is 120 degrees, the cosine and the sine function have a projected area ratio

Ie approximately 1.7: 1.

5 and 6, the third embodiment of the present invention includes a pair of jibs 5c and 6c. Jibs 5c and 6c have a generally concave shape with respect to slide 2c. As above, the jibs 5c and 6c guide the slide 2c during press operation.

The difference between the second and third embodiments of the invention is that each slide 2b, 2c has an opposite (concave / convex) shape with respect to the support of the respective jib 5b, 6b and jib 5c, 6c. It should be noted that There is no other difference.

In the third embodiment, the angle alpha α between each liner 11, 11 is also approximately 120 degrees. During operation, there is almost no temperature difference between the slide 2c and the jibs 5c and 6c, and there is no advantageous difference between the second and third embodiments.

However, when the slide 2c reaches a temperature higher than the temperatures of the jibs 5c and 6c, there is an advantage in the second embodiment. This temperature difference allows for thermal deformation of the slide 2c which is larger than the thermal deformation of the jibs 5c and 6c. In thermal anisotropic conditions, the second embodiment provides greater compensation for thermal strain. As a result, the present invention can be easily adapted to both precision press operation and various driving environments.

7 and 8, the fourth embodiment of the present invention includes a slide 2d operated between a pair of jibs 5d and 6d.

The pair of bolts 17 and 17 fixes the jibs 5d and 6d to the frame 1 of the opposite side of the slide 2d. A set of screws (not shown) secures a set of liners to the jib 6d. Another set of screws (not shown) secures a set of liners to the jib 5d. Bolts 22 secure each block 21, 21 to the side of each slide 2d opposite each jib 5d, 6d.

Spherical hollows 18 and 18 are arranged in the respective blocks 21 and 21. The spherical shoe 20 is rotatably fitted in each block 21. As will be described later, the flat portion on each spherical shoe 20, 20 enables sliding contact with each liner 11, 11 on each jib 5d, 6d.

In this embodiment, the jibs 5d and 6d and the wedges 12 are narrower than in the previous embodiment. Similarly, the jib holders 13 and 14 are smaller in overall dimensions. In the fourth embodiment, the jib 6d is in a groove (shown in the frame 1 but not shown). The single bolt 17 is screwed to secure the jib 6d with the frame 1 opposite the slide 2d. The single bolt 17 similarly secures the wedge 12 and the jib 5d.

The assembly method for the fourth embodiment is similar to the assembly method for the second and third embodiments. During assembly of the fourth embodiment, the bolts 22, 22 secure each block 21, 21 to the slide 2d. Spherical shoes 20, 20 are then inserted into the respective hollows 18, 18. Jib 6 receives slide 2d fixed and assembled to frame 1. Jib holders 13 and 14, wedges 12 and jibs 5 are installed and adjusted. After adjustment, the bolt 17 fixes the wedge 12 and the jib 5d to the frame 1.

During operation, the jibs 5d and 6d are formed of a general 'V-type'. Liner 11 is located on each side of the V-shape. The shoes 20, 20 provide two corresponding contact surfaces opposite each liner 11. Angular beta (β) is defined between each side of the V-type. The angle beta (β) is approximately 120 degrees.

Preferably, each shoe 20 saves cost while maintaining precision by replacing conventional multiple shoes. In other words, the multiple spherical shoes from the second and third embodiments are combined and moved as closely as possible.

The fourth embodiment is particularly advantageous for providing precision operation where space is limited and the press 50 or slide 2d must be small.

In each of the embodiments discussed above, the combination of at least one spherical shoe 7-10, 20 with a flat guide face sliding along the corresponding jib is an easy means to eliminate eccentricity and slide misalignment. Works.

Simple rotation of each spherical shoe easily maintains a planar contact between each liner 11 and the contact surface of each shoe. This design prevents line contact and smoothness from rupturing and minimizes scoring, scoring and equipment failure.

As an additional advantage for this design, since the jib is easily adjusted at approximately zero intervals, high precision is readily achieved without the need for reinforced (not shown) guide posts on dies (not shown).

The design allows for easy adaptation to a variety of product sizes, processing needs and temperature gradients, while maintaining high precision, simple fabrication and simple assembly.

The design also easily compensates for the eccentric force given on the slide during the adjustment operation. According to the invention, the spherical shoe and the angular jib corresponding to the hollow easily compensate for any eccentric force and maintain parallel operation. As a result, equipment life is extended, maintenance costs are reduced and production time is maximized.
