Description

Technical Field

[0001] The utility model relates to a guide column group, in particular to a stable steel ball guide column group. Background Art

[0002] In recent years, with the increasingly fierce competition in the automobile market, major automobile manufacturers have turned their attention to the automobile's own covering parts and related stamping parts (hereinafter collectively referred to as parts) in the direction of developing and researching new models. Parts tend to be more complex, high-strength, and increased in output, and the quality requirements for parts are getting higher and higher. The corresponding requirements for mold manufacturing are also greatly improved. Therefore, in the mold production process, guide stability is also particularly important.

[0003] There are two types of existing guide post groups, one is a sliding guide post group, and the other is a ball guide post group (a ball bushing is installed on the guide post), hereinafter referred to as ball guide posts. Among them, the sliding guide post group has low guiding accuracy, is easy to wear, and has a short service life. Compared with the sliding guide post, the ball guide post has greatly improved in accuracy and service life, but this type of guide post has certain limitations, that is, it has an effective movable range. When the bottom dead point height of the guide post group exceeds the effective range, there is a great risk of failure in the guidance, and even safety hazards may occur during the production process of the product. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a stable steel ball guide column group, which effectively solves the certain limitations of the current guide column, that is, it has an effective movable range. When the bottom dead point height of the guide column group exceeds the effective range, the guide will have a great risk of failure, and even safety hazards will occur in the production process of parts.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: the utility model includes a sliding base, a buffer spring, a ball bushing, a cover plate, a guide column, a guide column base, a first screw, a thin head screw, a pin, an upper mold base, a through hole, a first screw hole, a thin head screw hole, a second screw, a lower mold base and a second screw hole. The sliding base is installed on the upper mold base through the first screw, a ball bushing is inserted into the interior of the sliding base, a buffer spring is installed on the outer side of the ball bushing, a cover plate for limiting the ball bushing is installed on the bottom end of the sliding base through the thin head screw, the guide column base is installed on the lower mold base through the second screw, a guide column is installed in the middle of the guide column base, through holes are provided at the sliding base and the upper mold base corresponding to the guide column position, first screw holes are opened at the sliding base and the upper mold base corresponding to the first screw position, and thin head screw holes are opened at the sliding base and the thin head screw corresponding to the thin head screw position.

[0006] Preferably, pins are provided between the sliding base and the upper die base and between the guide column base and the lower die base.

[0007] Preferably, the pin is a φ12*40 pin.

[0008] Preferably, the thin head screw is an M6*16 thin head screw.

[0009] Preferably, the first screw and the second screw are both M12*50 screws.

[0010] Preferably, the guide column base and the lower mold base are both provided with second screw holes at positions corresponding to the second screws.

[0011] Beneficial effect: The one-time action process of the utility model when used includes two stages: the first stage, at the beginning, the upper die seat is at the upper dead point of the machine tool, the lower die seat is on the working table of the punch press, and the lower die seat is stationary during the entire working process. When the mold starts to work, the mold guide starts, the guide post contacts the ball bushing, and rolling friction is performed, thereby playing a guiding role. The buffer spring plays a buffering role at the moment when the guide post contacts the ball bushing, making the guidance smoother. After the mold reaches the lower dead point, the guide post and the sliding guide sleeve of the sliding base reach the minimum closing height. At this time, since the ball bushing is installed inside the sliding guide sleeve of the sliding base, the risk of guide failure is completely eliminated. In the second stage, the upper die machine tool begins to open, the guide post and the ball bushing still maintain the guide, the buffer spring is released, and the ball bushing is lifted accordingly. When the guide post and the ball bushing are out of contact, one action is completed. The utility model has a novel structure and an ingenious design. It not only improves the accuracy and service life of the guide post group, but also greatly reduces its limitations and eliminates various risks and safety hazards that may occur in the production process of the mold.
