Abstract

PURPOSE:To cancel an opening angle and to execute pressing with high accuracy by providing a slide in such a manner that the center of the pressing load transmission thereof is deviated forward from the center of a die mounting part coinciding with the load center of the slide. CONSTITUTION:The slide 3 which is disposed above a bolster so as to face the same is connected via an adjusting screw bar 9 and a connecting member 10 to a connecting rod 2 attached freely rotatably to a crank shaft 1. The center line of the bar 9 is deviated forward by C from the center line C1 of the slide load of a press machine in this state and the central point (to be the center of the pressing load transmission) of the lower connecting part exists at Co. Then the slide 3 deforms a frame 7 in the direction for canceling the inclination of a slide guide part after rotating around the center Co of the connecting part by as much as the guide clearance. The opening angle thereof is thus decreased.

(Conventional technology The gap frame press is also called a C-shaped frame press, and is widely known and used in the industrial world as shown in Figure 1 of JIS BOIII. However, the frame of this press is approximately C-shaped when viewed from the side. Due to its shape, a so-called opening phenomenon occurs during press work, which is a weak point of gap frame presses.

(Problems to be Solved by the Invention) In a general gap frame press, [2eK] As shown in [2eK], the connection between the lower part of the connecting rod (including the adjusting threaded rod part) and the slide part, the upper part of which is connected to the crankshaft of the press. The center of the slide coincides with the center of the slide, so when a load P is applied to the slide along the load center line (Cr) of the slide of the press machine, the frame stretches and at the same time the guide part of the slide moves at an angle α. Lean with. Following this inclination, the slide also inclines in the same way, and the center of the connection between the lower part of the connecting rod and the slide part moves backward (rightward in Fig. 2) by 6/, so the rotational moment Pe' It acts in the direction of increasing the tilt angle, and the guide part rotates by the rear balance, and the tilt of the slide increases by the total angle β, and an opening angle of α + β is created between the top surface of the bolster and the bottom surface of the slide, and the punch and die This disturbs the center line of the machine and has a negative impact on product processing accuracy and mold life.

As a countermeasure against this problem, it is possible to use a press machine with a large capacity compared to the working load, but needless to say, a press machine with a large capacity is large in size and occupies a large floor area, so it is not desirable in terms of energy conservation and has no economic benefits.

(Means for Solving the Problems) The present invention aims to easily provide a gap frame press equipped with a slide and a device with high forming precision.
One feature of the present invention is that the slide is provided eccentrically by e (towards the left in Fig. 1) in front of the center of pressure load transmission (the center of the connecting portion between the slide and the connecting rod), so that it can accommodate press work loads. The opening angle of the gap frame (that is, also the opening angle of the lower surface of the slide) can be canceled by the rotational moment of the slide in the opposite direction about the connecting portion.

(Embodiments of the Invention) The present invention will be described below based on the embodiments shown in FIGS. 1 and 3. In the figure, the gap frame 1, which has a substantially C-shaped side surface, is made of an integral structure, and a bolster 4 is disposed on the lower end surface of the opening. As shown in detail, the connecting rod 2KJ, which is rotatably attached to the crankshaft l, is connected via the adjusting threaded rod 9 and the connecting member 10.In this state, the center line of the weight of the slide of the press machine With respect to c1, the center line of the adjusting screw rod 9 is deviated forward by e, and the center point of the lower connecting part (the center of pressure load transmission) is at C6. will be explained with reference to Fig. 1. '' □ When a working load of P is applied to the slide 3 along the slide center line, the frame 7 will extend and the guide portion 8 of the slide 3 will move to α as in the conventional machine. Therefore, the center Co of the connecting portion tends to move backward by e', but in the case of the present invention, the center C8 of the connecting portion of the connecting rod 2 and slide 3 is shifted forward by e from the slide center line CI. Therefore, slide 3 has at least pX (e-
e-'') acts in the direction of arrow M in the figure (in the opposite direction to the conventional machine, and due to this action, the slide 3 is in the connecting part) 6c0 as the center, and the moment moves by the clearance of the first part of the guide (
After rotating (very small amount), the frame 7 is deformed in a direction that cancels the inclination α of the slide guide part 8, and is rotated by the total angle β', and as a result, the opening angle ' is reduced to α-β'. - However, a bolt hole die clamper or a shank hole is provided on the underside of the slide 3 of a normal press for mounting the mold, but even in the case of a side hole, the center of the mounting part must be arranged so that it coincides with the slide center C8. Therefore, in the normal case, the load center P of the jar is applied along the slide center line C1. However, in a press with a conventional structure in which the center of pressure load transmission of the slide is aligned with the center of the slide, the above-mentioned deaf mounting - part of the center, that is, the load center of the die, is moved backward from the center of the slide (towards the right in Fig. 1). Even if the slide is deviated, the relationship between the load center line of the slide and the center line of pressure load transmission of the slide is exactly the same.
