Description

Technical Field

[0001] The utility model relates to the technical field of drive guide plates in stamping dies, in particular to an over-travel roller guide plate. Background Art

[0002] The driving guide used in the mold is generally a composite driving guide, which is generally composed of a copper driving guide containing graphite and a corresponding steel driving guide to form a wedge-shaped structure to work together. The driving stroke of the driving guide depends on the thickness and angle of the driving guide. The steel driving guide is usually installed on the upper mold, and the copper driving guide is installed on the movable slide of the lower mold. When the mold is closed, the copper driving guide is driven by the steel driving guide to complete a reciprocating stroke, that is, to complete a stamping work.

[0003] The existing copper drive guide plate is an integral copper alloy structure, and graphite is inlaid on the copper drive guide plate. During operation, the copper drive guide plate is subjected to greater force, and the R corner is prone to wear and roughening, resulting in damage to the copper drive guide plate. Utility Model Content

[0004] The utility model aims to provide an over-travel roller guide plate. The copper drive guide plate adopts a split structure, which can solve the technical problems of wear, burring and damage of the copper drive guide plate due to large force during the mold closing process.

[0005] To achieve the above-mentioned purpose, the utility model is designed to provide an over-travel roller guide plate, comprising a base, a flat guide plate, a roller, and a pin shaft. The upper end of the base is provided with an inclined surface, which is inclined from top to bottom along the height direction of the base, and the inclined surface is inclined toward the direction of a steel driving guide plate installed on the upper mold. The flat guide plate is detachably mounted on the inclined surface; the roller is mounted on the middle part of the base through a pin shaft, and the roller and the flat guide plate are located on the same side of the base.

[0006] As a preferred solution, a roller groove is provided in the middle of the base, and the roller and the pin shaft are arranged in the roller groove.

[0007] As a preferred solution, it also includes a guide sleeve, which is embedded in the interior of the roller and is rollingly connected to the pin.

[0008] As a preferred solution, it also includes gaskets, which are installed on both sides of the roller and move with the roller.

[0009] Furthermore, the side of the gasket in contact with the substrate is inlaid with graphite. The graphite inlaid on the gasket can play a lubricating role and ensure the stability of the roller rotation.

[0010] As a preferred solution, it also includes a pin, the two ends of which are respectively installed in the base and the pin shaft. The pin is used to fix the base and the pin shaft to ensure that the pin shaft does not move left and right.

[0011] As a preferred solution, the main body of the flat guide plate is made of copper, and the working surface of the flat guide plate contains graphite. Since the copper guide plate is easy to replace after being worn, the flat guide plate is detachably connected to the base body by screws, which increases the convenience of replacement.

[0012] Beneficial effects of the utility model:

[0013] The utility model provides an over-travel roller guide plate, the copper drive guide plate adopts a split structure, the base body is made of ordinary steel, which can greatly reduce the material cost, a detachable flat guide plate is installed on the top of the base body as the copper drive guide plate, and a roller structure is installed on the side of the base body to roll with the steel drive guide plate of the upper mold to avoid direct contact between the base body and the steel drive guide plate, increase the risk of base body wear, and thus cause the drive guide plate to wear and deform.
