Problems solved by technology

If there is a phase difference between the left and right or front and rear crankshafts in the multi-point press, it will directly lead to poor vertical and parallel accuracy of the lower bottom of the slider to the upper plane of the worktable, affecting the quality of stamping parts, and even causing damage to the mold
[0003] The traditional crankshaft phase adjustment method is to install the two crankshafts on the press for calibration and debugging, which is not only labor-intensive and low in work efficiency, but also requires the crankshaft to be disassembled for secondary assembly if necessary, which is very inconvenient to operate

Embodiment 1

[0038] Embodiment 1: As shown in the figure, a method for adjusting the crankshaft phase of a two-point press includes the following specific steps:

[0039] (1) Coaxially sleeve the first coupling 11 on the first crankshaft 1, and then process the first radial positioning hole 12 between the first coupling 11 and the first crankshaft 1, and place the first radial positioning hole 12 between the first coupling 11 and the first crankshaft 1. A first radial positioning pin is inserted into the radial positioning hole 12, and the two are in an interference fit, so that the first crankshaft 1 and the first coupling 11 are fixed, and then the ends of the first coupling 11 and the first crankshaft 1 are fixed. A first axial positioning hole is machined between the two parts, and a first axial positioning pin 13 is installed in the first axial positioning hole, and the two are in an interference fit, such as figure 2 The second coupling 21 and the third coupling 22 are respectively ...

Embodiment 2

[0048] Embodiment 2: As shown in the figure, a method for adjusting the crankshaft phase of a four-point press, after completing the phase adjustment of the two-point crankshaft in Embodiment 1, the following steps are performed:

[0049] (9) Install the adjusted two-point crankshaft into the press, and fix the first gear 15 and the second gear 36 coaxially on the left end of the first crankshaft 1 and the right end of the second crankshaft 3 respectively, as shown in Figure 12 shown;

[0050] (10) Rotate the double-point crankshaft until the crankshaft part is in a horizontal position and fix it, install the third crankshaft 7 in the press, the third crankshaft 7 is parallel to the double-point crankshaft, and rotate the crankshaft part 71 of the third crankshaft 7 After reaching the horizontal position for positioning, the crankshaft portion 71 of the third crankshaft 7 is arranged opposite to the crankshaft portion 14 of the first crankshaft 1 in the double-point crankshaf...

Abstract

The invention discloses a crankshaft phase adjusting method of a multi-point press, which is suitable for synchronous consistency adjustment of crankshaft phases of a two-point press and a four-point press, is quick and reliable in adjusting operation and high in adjusting efficiency, and can greatly shorten the repeated operation time. The operation precision of the adjusted press machine can reach or exceed the precision range required by the standard. In addition, the method is wide in application range and high in operability.

Description

technical field [0001] The invention relates to a press, in particular to a crankshaft phase adjustment method of a multi-point press. Background technique [0002] The two-point or four-point press uses the crankshaft and connecting rod to convert the rotary motion of the motor into the vertical motion of the slider, so as to realize the stamping of the product, but in the multi-point press, the consistency of the operation of each crankshaft is particularly critical. The key factor to ensure the stamping accuracy of the press. If there is a phase difference between the left and right or front and rear crankshafts in the multi-point press, it will directly lead to poor vertical and parallel accuracy of the lower bottom of the slider facing the upper plane of the worktable, affecting the quality of the stamping parts, and even causing serious damage to the mold . [0003] The traditional crankshaft phase adjustment method is to install two crankshafts on the press for cali...
