Description

Technical Field

[0001] This utility model relates to the field of stamping dies, and in particular to a wedge mechanism for stamping dies. Background Technology

[0002] Wedge mechanisms are commonly used in stamping dies to convert the vertical motion of a stamping machine into lateral motion. One type of wedge mechanism has a planar connection between the base and the slider for force transmission, a V-shaped connection between the slider and the drive block for force transmission, and a connection between the slider and the base via side slides on both sides, with the side of the slider contacting and rubbing against the side of the side slides.

[0003] Currently, the side of the slide plate participates in guiding the slide and bears lateral forces. However, the side plate is fixed to the base with bolts, resulting in insufficient lateral force resistance, reduced guiding accuracy, and shortened service life. It can even lead to bolt breakage. In addition, the gap between the current wedge mechanism base and the slide plate cannot be adjusted. After wear, the gap will increase, requiring the replacement of the side plate.

[0004] Currently, when replacing the spring, it cannot be removed from the back of the slider; the wedge must be disassembled for maintenance and replacement, which is inconvenient and inefficient. Therefore, it is necessary to improve this structure to overcome these shortcomings. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a wedge mechanism for stamping dies. This utility model is achieved through the following technical solution:

[0006] A wedge mechanism for a stamping die includes a drive block, a base, a slider, and side slides. A T-shaped slide rail is provided on the base, and a U-shaped guide rail slides along the T-shaped slide rail. The U-shaped guide rail is mounted on the slider and slides synchronously with it. A side slide is fixedly mounted on each side of the T-shaped slide rail. A first contact surface, shaped like a "V," is provided at the lower end of the slider. A second contact surface, also shaped like a "V," is provided on the drive block. The first and second contact surfaces are in contact. A mounting hole is provided through the slider, and a spring is installed within the mounting hole.

[0007] In the above technical solution: the U-shaped guide rail at the upper end of the slider slides within the T-shaped guide rail on the base, allowing the slider to absorb and bear lateral forces; in addition, the V-shaped contact surface at the lower end of the slider and the contact surface on the drive block are in a V-shape fit, so that the lower end of the slider can absorb and bear lateral forces; the mounting hole is used to install a spring; the spring is used to reset the slider.

[0008] A further feature of this invention is that: a mounting groove is provided on the side of the base, a first inclined surface is provided in the mounting groove, a hanging platform is provided on the side slide, a second inclined surface is provided on the hanging platform, the inclination angle of the first inclined surface is 1 degree, the inclination angles of the first inclined surface and the second inclined surface are the same, and the first inclined surface and the second inclined surface are in contact.

[0009] In the above technical solution: the mounting groove is used to set the hanging platform; the length of the mounting groove is greater than the length of the hanging platform, so that the relative position between the side slide plate and the mounting groove can be adjusted; the first inclined surface and the second inclined surface cooperate so that the gap between the side slide plate and the top surface of the U-shaped guide rail can be adjusted by adjusting the relative position between the two side slide plates and the mounting groove, so that the gap can still be adjusted to a suitable level after wear.

[0010] A further feature of this invention is that a detachable fixing plug is provided in the mounting hole, and the fixing plug is located behind the spring.

[0011] In the above technical solution: the fixing plug is used to limit the end position of the spring.

[0012] A further feature of this invention is that a forced pull-back mechanism is fixedly provided on the slider, and a limit groove is provided on the drive block, wherein the forced pull-back mechanism engages with the limit groove.

[0013] In the above technical solution, the combination of forced pull-back and limit groove is used to force the slider to reset when the spring fails.

[0014] A further feature of this invention is that the slider is provided with a V-shaped guide rail, the V-shaped guide rail moves synchronously with the slider, and the first contact surface is disposed on the V-shaped guide rail.

[0015] In the above technical solution: the V-shaped guide rail is used to reduce wear and makes it easier to replace the V-shaped guide rail after wear.

[0016] A further feature of this invention is that a travel tube is fixedly installed on the base, and the travel tube can contact or separate from the slider.

[0017] In the above technical solution: the stroke tube is used to fix the slider at the bottom dead center position.

[0018] A further feature of this invention is that the cross-section of the U-shaped guide rail is in the shape of an "I".

[0019] In the above technical solution, the cross-section of the U-shaped guide rail is "I" shaped, which improves the ability to withstand lateral forces.

[0020] A further feature of this invention is that a solid self-lubricating material is embedded in the T-shaped slide rail and the U-shaped guide rail.

[0021] In the above technical solution, self-lubricating materials are used to improve the life and wear resistance of T-shaped slide rails and U-shaped guide rails.

[0022] This utility model discloses a wedge mechanism for stamping dies, which, compared with the prior art:

[0023] This utility model, by setting up a T-shaped slide rail, a U-shaped guide rail, a first contact surface, and a second contact surface, makes the side of the side slide no longer participate in the guiding slide, and the side slide no longer bears the lateral force. Instead, the T-shaped slide rail, the U-shaped guide rail, the first contact surface, and the second contact surface bear the lateral force, which improves the wedge's ability to bear lateral force and the guiding accuracy of the slider, and increases the wedge's service life.

[0024] This utility model also allows the gap between the side slide plate and the top surface of the U-shaped guide rail to be adjusted by adjusting the relative position of the side slide plate in the direction of the mounting groove, so that after wear, there is no need to replace the side slide plate, but only adjustment is required.

[0025] This invention also features a through mounting hole and a fixing plug, allowing the spring to be removed directly from the back of the slider after the fixing plug is removed, without disassembling the wedge, making spring replacement and removal more convenient.
