The mechanism generally includes: a wedge, also known as an active wedge, which acts as a force-applying body during operation; a slider, also known as a working wedge, which is a force-bearing body during operation; and auxiliary devices such as a reverse side block, a pressure plate, a guide plate (guide rail), a wear plate, a spring, and a screw. Because the wedge mechanism has the advantages of increasing the amplitude of force, changing the direction of force, and being simple and easy to manufacture, various standard wedges and non-standard wedges are widely used in automobile stamping die structures.

In automobile stamping dies, the guiding accuracy and stability of the sliding block in the cam mechanism in its working direction have become one of the important factors affecting the quality of stamping parts. How to improve the guiding accuracy and stability of the sliding block in the cam mechanism has become one of the technical issues that technicians in related fields need to consider and solve in the process of designing stamping dies.

[0024] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.
[0025] See also Figures 1 to 4 . It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the utility model without substantially changing the technical content.
[0026] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.
[0027] See also Figure 4The utility model provides an anti-skid inclined wedge mechanism, comprising a first driving block 1 and a second driving block 2, a sliding block 3 is installed between the first driving block 1 and the second driving block 2, the first driving block 1 and the second driving block 2 interact with each other to drive the sliding block 3 to move along a working direction, an anti-skid module 4 is arranged between the second driving block 2 and the sliding block 3, the anti-skid module 4 generates a force to prevent the lateral movement of the sliding block 3 along the working direction, so that the sliding block 3 does not deviate from the working direction when working, thereby improving the guiding accuracy and stability of the sliding block 3 in the working direction when the anti-skid inclined wedge mechanism is working.
[0028] In another embodiment, see Figures 1 to 3 The anti-skid module 4 includes two first guide sliding surfaces 41 symmetrically arranged on the sliding block 3 and two second guide sliding surfaces 42 symmetrically arranged on the second driving block 2; the first guide sliding surface 41 intersects with the plane where the sliding direction of the sliding block 3 is located, and the first guide sliding surface 41 and the second guide sliding surface 42 fit together, so that when the sliding block 3 moves along the designed working direction, the two first guide sliding surfaces 41 are respectively fitted with the two second guide sliding surfaces 42 to generate lateral forces along the moving direction of the sliding block 3. Because the two first guide sliding surfaces 41 are symmetrically designed, the forces generated by the two first guide sliding surfaces 41 offset each other, preventing the sliding block 3 from moving sideways, thereby improving the guiding accuracy and stability of the sliding block 3 in the working direction when the anti-skid wedge mechanism is working; this embodiment provides a specific structural form of the anti-skid module 4.
[0029] In another embodiment, see Figure 1 and Figure 2 The intersection angle between the first guide surface 41 and the plane where the sliding direction of the sliding block 3 is located is in the range of 15-30°. If the angle is too small, the anti-skid effect is not good, and if the angle is too large, it will affect the normal sliding of the sliding block 3.
[0030] In another embodiment, see Figure 1The first driving block 1 is fixedly mounted on the upper die base of the mold, the sliding block 3 is mounted on the first driving block 1, and the sliding block 3 can move along the guide sliding surface on the first driving block 1, and the second driving block 2 is fixedly mounted on the lower die base of the mold. Because the guide sliding surfaces of the upper die base, the lower die base and the first driving block 1 have been fully disclosed in the prior art, no specific illustration is given. When the first driving block 1 is driven by an external force, it drives the sliding block 3 to move together. The sliding block 3 is provided with a first inclined surface 31, and the second driving block 2 is provided with a second inclined surface that is in contact with the first inclined surface 31. 21, the inclination direction of the first inclined surface 31 is the movement direction of the sliding block 3. The design of the first inclined surface 31 and the second inclined surface 21 enables the sliding block 3 to generate a movement in a direction different from the direction of the external force acting on the first driving block 1, so that the sliding direction of the sliding block 3 in the anti-side sliding wedge mechanism can be changed when working, instead of only being the same as the direction of the external force acting on the first driving block 1. For example, when a vertical force is applied to the first driving block 1, due to the design of the first inclined surface 31 and the second inclined surface 21, the sliding block 3 undergoes an oblique movement deviating from the vertical direction.
[0031] In another embodiment, see Figure 1 There are two first inclined surfaces 31 and they are symmetrically arranged on the sliding block 3, and there are two second inclined surfaces 21 and they are symmetrically arranged on the second driving block 2. The two first inclined surfaces 31 are respectively fitted with the two second inclined surfaces 21. Compared with the case where only one first inclined surface 31 and one second inclined surface 21 are fitted, the technical solution of this embodiment can better ensure the stability of the sliding block 3 when it moves along the working direction.
[0032] In another embodiment, see Figure 2 and Figure 3 The two first guide sliding surfaces 41 are located between the two first inclined surfaces 31, and the two second guide sliding surfaces 42 are located between the two second inclined surfaces 21. The position, size, angle, relative and shape of the two first guide sliding surfaces 41 and the two second guide sliding surfaces 42 can be adjusted and set according to the usage, and the design is flexible.
[0033] In another embodiment, the two first inclined surfaces 31 are located between the two first guide sliding surfaces 41 . This embodiment is an extension of the previous embodiment, and the specific structural details are not repeated here.
[0034] In another embodiment, see Figures 1 to 3The two first guide sliding surfaces 41 are symmetrically arranged on the lower surface of the sliding block 3 with the central axis of the anti-skid wedge mechanism, the two second guide sliding surfaces 42 are arranged on the upper surface of the second driving block 2, the two first inclined surfaces 31 are symmetrically arranged on the lower surface of the sliding block 3 with the central axis of the anti-skid wedge mechanism, and the two second inclined surfaces 21 are arranged on the upper surface of the second driving block 2. The technical solution of this embodiment has better stability than other solutions that are not symmetrically designed with the central axis of the anti-skid wedge mechanism.
[0035] In other embodiments, Figure 1 As shown, a wear-resistant plate 5 is installed between the first guide sliding surface 41 and the second guide sliding surface 42, and a wear-resistant plate 5 is installed between the first inclined surface 31 and the second inclined surface 21. The shape and thickness of the wear-resistant plate 5 can be selected according to actual production conditions. The design of the wear-resistant plate 5 increases the service life of the anti-side slip wedge mechanism.
[0036] In summary, the utility model is designed to prevent the sliding block 3 from moving sideways in the working direction through the anti-skid module 4, so that the sliding block 3 does not deviate from the working direction during operation, thereby improving the guiding accuracy and stability of the sliding block 3 in the working direction when the anti-skid inclined wedge mechanism is working; specifically, the two first guide sliding surfaces 41 symmetrically arranged on the sliding block 3 and the two second guide sliding surfaces 42 symmetrically arranged on the second driving block 2, the first guide sliding surface 41 intersects with the plane where the sliding direction of the sliding block 3 is located, and the first guide sliding surface 41 and the second guide sliding surface 42 are fitted together, so that when the sliding block 3 moves in the designed working direction, the two first guide sliding surfaces 41 are respectively fitted with the two second guide sliding surfaces 42 to generate a lateral force in the moving direction of the sliding block 3. Because the two first guide sliding surfaces 41 are symmetrically designed, the forces generated by the two first guide sliding surfaces 41 offset each other, preventing the sliding block 3 from moving sideways, thereby improving the guiding accuracy and stability of the sliding block 3 in the working direction when the anti-skid inclined wedge mechanism is working. Therefore, the utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
