Description

Method for adjusting relative position of mold base of fastener forming machine

The present invention relates to a method of adjusting a mold base, and more particularly to a method of adjusting the relative position of a mold base of a fastener forming machine.

Generally, the alignment of the male mold base and the female mold base of the fastener forming machine is dependent on the size of the fastener and the observed value of the fastener operator, and the relative position between the male mold base and the female mold base is adjusted according to the experience.

However, performing one-time mold adjustment in such a manner is time consuming and is not conducive to research and development and mass production. Moreover, manual long-time repeated mode adjustment is prone to human error, which results in shortened die life, product inconsistent with customer specifications, consumable wire, and increased manufacturing costs. Moreover, due to the different experience of each operator, the quality of the resulting fastener products will vary.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a method of adjusting the relative position of a mold base of a fastener forming machine by optically measuring a workpiece sample to obtain a recommended adjustment amount to standardize the mold adjustment technique and guide the use thereof. Accurately and quickly adjust the mold base to the best position.

First, a fastener forming machine is provided. The fastener forming machine includes a first mold base and a second mold base disposed opposite to each other, wherein the first mold base is fixed with a first mold and the second mold base is fixed with a second mold. Next, controlling the first mold base to move to the second mold base to press the first mold to press the first blank on the second mold to form a first workpiece sample, wherein the first workpiece sample has a first head and The first pole. Then, a first adjustment step is performed to adjust the movement of the first mold base in a vertical plane by the first adjustment amount. Next, controlling the first die holder to move toward the second die holder to press the first die to press the second blank on the second die to form a second workpiece sample, wherein the second workpiece sample has a second head and Second pole. Then, a second adjustment step is performed to adjust the yaw of the first mold base in the vertical plane by the second adjustment amount. And then controlling the movement of the first mold base to the second mold base to press the first mold to the third blank on the second mold to form a third workpiece sample, wherein the third workpiece sample has a third head and Third pole. Next, the first eccentric amount of the center of the first head and the center of the first shank, the second eccentric amount of the center of the second head and the center of the second shank, and the third head are measured by the optical measuring device The third eccentric amount of the center and the center of the third shank. Then, calculating, according to the first eccentric amount, the second eccentric amount, and the third eccentric amount, a first actual displacement amount of the first mold base corresponding to the first adjustment amount in the first adjustment step, and a corresponding one in the second adjustment step The second actual displacement amount of the first mold base of the second adjustment amount. Then, a set of recommended adjustment amounts is calculated according to the first actual displacement amount and the second actual displacement amount. Finally, adjust the first mold base with the recommended adjustment amount to make the middle of the first mold The core line overlaps the centerline of the second mold.

According to an embodiment of the invention, the step of calculating the first actual displacement amount and the second actual displacement amount comprises the following steps. A first offset position of a center of the first stem relative to a center of the first head is defined according to the first eccentric amount.

A third offset position of the center of the third stem relative to the center of the third head is defined in accordance with the third amount of eccentricity. The first actual displacement amount and the second actual displacement amount are calculated using the first offset position, the second offset position, and the third offset position.

According to an embodiment of the invention, the first actual displacement amount is calculated according to the distance between the second offset position and the first offset position.

According to an embodiment of the invention, the second actual displacement amount is calculated according to the distance between the third offset position and the first offset position.

Before the first mold base 110 has not been adjusted, step 302 may be performed to control the movement of the first mold base 110 to the second mold base 120 to press and fix the first mold 111 to the second mold. The first blank on 121 forms a first workpiece sample 400 as shown in FIG. 5A, wherein the first workpiece sample 400 has a first head 410 and a first stem 420. Next, a first adjustment step 303 is performed to adjust the movement of the first mold base 110 in the vertical plane by the first adjustment amount. In step 303, the first mold unit 110 can be firstly moved to adjust the vertical movement of the first mold base 110 so that the first mold 111 protruding from the first mold base 110 is formed on the vertical surface.

The transposition 710 and the photographing device 720 are electrical connection processing units 730. The swivel 710 includes a motor 711 and a turntable 712 that can be controlled to rotate by the motor 711. The turntable 712 can be used primarily to hold a workpiece to be tested (eg, the first workpiece sample 400, the second workpiece sample 500, or the third workpiece sample 600). The photographing device 720 can be disposed on the adjusting seat 740, so that the user can adjust the relative position of the photographing device 720 and the turntable 712 through the adjusting seat 740. In some examples, a light source 750 can be placed alongside the turntable 712 to provide the desired light for the imaging device 720 to take images. In addition to controlling the operation of the rotating base 710 and the photographing device 720, the processing unit 730 can also process the image obtained by the photographing device, and calculate the relevant values of the semi-finished product (or the finished product) according to the image, such as the head thickness, the length of the rod, The amount of eccentricity of the head and the center of the shaft.

Referring to FIG. 4 and FIG. 6 again, in step 307, the center 411 of the first head portion 410 of the first workpiece sample 400 shown in FIG. 5A and the center 421 of the first rod portion 420 can be obtained by the optical measuring device 700.

Here, the “first actual displacement amount” referred to herein refers to the displacement amount at which the first mold base 110 actually moves when the first adjustment unit 210 is adjusted according to the first adjustment amount. For example, the number of turns (or angle) of the first adjustment unit 210 is rotated to correspond to the distance that the first die holder 110 actually moves. Similarly, the "second actual displacement amount" refers to the displacement amount at which the first mold base 110 actually moves when the second adjustment unit 220 is adjusted according to the second adjustment amount. For example, the number of turns (or angle) of the second adjustment unit 220 is rotated to correspond to the distance that the first die holder 110 actually moves.

Please refer to FIG. 7 , which is a schematic diagram of defining an offset position of a workpiece sample according to an eccentric amount according to an embodiment of the present invention.
