Description

Technical Field

[0001] The utility model relates to the field of stamping dies, in particular to a V-shaped guide rail with less wear. Background Art

[0002] Currently in the field of stamping dies, especially in the wedge mechanism of stamping dies, V-shaped guide rails are often used as precision guides; in another case, when the sliding block in the die is reset, it is often reset by the elastic potential energy of the spring stretching. In order to prevent the sliding block from being unable to reset when the spring fails, a forced reset plate is often designed and installed on the mold sliding block to force the sliding block to reset, preventing the sliding block from being unable to reset when the spring reset force is insufficient, thereby causing damage to the mold.

[0003] However, due to the arrangement of the forced reset plate, the V-shaped guide rail is subjected to greater friction and more severe wear during the return stroke, and is prone to jamming. Therefore, it is necessary to improve such a structure to overcome the above defects. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a V-shaped guide rail with less wear. The utility model is achieved through the following technical solutions:

[0006] In the above technical solution: the base plate and the slider together constitute the basic structure of the slide rail to realize the function of the slide rail; the V-shaped convex surface and the V-shaped concave surface are used to realize guiding and positioning; the sliding groove and the sliding block are used to realize sliding, and play a role in guiding and positioning when the V-shaped convex surface and the V-shaped concave surface are not in contact; the setting of the first inclined surface and the second inclined surface makes the V-shaped convex surface and the V-shaped concave surface not in contact during the return stroke, thereby reducing friction and avoiding jamming; the elastic element is used to provide elastic force to overcome friction.

[0007] The utility model is further configured as follows: a clearance groove is also provided on the sliding block, and the clearance groove is located in the middle of the V-shaped concave surface.

[0009] The utility model is further configured as follows: an avoidance plane is also provided on the bottom plate, the avoidance plane is provided in the middle of the V-shaped convex surface, and the avoidance plane corresponds to the position of the give way groove.

[0010] In the above technical solution: the avoidance plane is set to remove the sharp end, thereby further preventing the V-shaped concave surface from being scratched by the V-shaped convex surface.

[0011] The utility model is further configured as follows: the width of the avoidance plane is smaller than the width of the give way groove.

[0012] In the above technical solution: the width of the avoidance plane is smaller than the width of the give-way groove, so that the avoidance plane does not contact the inner wall of the give-way groove at all.

[0013] The utility model is further configured as follows: an angle between the first inclined surface and the bottom surface of the bottom plate is not greater than 0.5 degrees.

The utility model provides the sliding block and the sliding groove so that when the V-shaped concave surface and the V-shaped convex surface are not in contact, the limiting and guiding can be achieved through the contact between the sliding block and the sliding groove.

Among them, the width of the base plate 10 and the slider 20 are consistent; preferably, the elastic element is a spring; the inclination angle of the inclined part of the V-shaped convex surface 101 is 30 degrees; the inclination angle of the inclined part of the V-shaped concave surface 201 is also 30 degrees; during the push stroke, the first inclined surface 102a and the second inclined surface 202a are not in contact, and the V-shaped convex surface 101 and the V-shaped concave surface 201 remain in contact; during the return stroke, the first inclined surface 102a and the second inclined surface 202a remain in contact, and the V-shaped convex surface 101 and the V-shaped concave surface 201 are not in contact.

[0023] like Figure 1-3 As shown, the utility model provides a V-shaped guide rail with less wear, the slider 20 is further provided with a clearance groove 203, and the clearance groove 203 is located in the middle of the V-shaped concave surface 201. The cross section of the clearance groove 203 is in an arc shape.

[0024] like Figure 1-3 As shown, the utility model proposes a V-shaped guide rail with less wear, wherein the bottom plate 10 is further provided with an avoidance plane 103, the avoidance plane 103 is provided in the middle of the V-shaped convex surface 101, and the avoidance plane 103 corresponds to the position of the give way groove 203. The avoidance plane 103 is parallel to the bottom surface of the bottom plate 10; and a chamfer is provided at the position where the avoidance plane 103 meets the V-shaped convex surface 101.

[0025] like Figure 1-3 As shown, the utility model provides a V-shaped guide rail with less wear, and the width of the avoidance plane 103 is smaller than the width of the give way groove 203.
