The description in this section is for several exemplary embodiments only, and the present invention is not limited only to the scope of the embodiments described. It is within the scope of the present disclosure and protection that the same or similar prior art means and some features of the embodiments may be interchanged.
The term "connected" in the specification includes both direct connection and indirect connection.
The utility model discloses a stripper plate slide block mechanism, and fig. 1 to 4 are schematic structural diagrams of the stripper plate slide block mechanism in an embodiment of the utility model; referring to fig. 1 to 4, the stripper plate slider mechanism includes a driving block 1, a guide slider 2 and a punch 3, and the punch 3 is disposed at the bottom of one side of the guide slider 2.
The driving block 1 is provided with an inner cavity 11, and the inner cavity 11 is provided with an inclined guide rail 12; the guide slide block 2 is provided with an oblique slide rail 21, and the oblique slide rail 21 is embedded with the oblique guide rail 12 of the driving block 1. A guide groove 13 is formed in the driving block 1, and a guide plate 22 is arranged on the guide sliding block 2; the guide plate 22 can slide along the guide groove 13 and plays a guiding role when the driving block 1 and the guide slide block 2 move relatively.
When the driving block 1 and the guide slider 2 are in a first posture and the movement of the guide slider 2 in the first direction is limited (as shown in fig. 3, the guide slider 2 is located on the lower template 4 at this time), the driving block 1 and the guide slider 2 generate relative motion, and the driving block 1 slides along the inclined slide rail 21 of the guide slider 2 through the inclined guide rail 12; so that the movement of the driving block 1 along the first direction generates the movement of the guide slide block 2 along the second direction, and further drives the punch 3 to move along the second direction, and the punch 3 can be inserted into or pulled out of the inner cavity of the product 5. The first direction may be perpendicular to the second direction. In an embodiment, the first direction is a vertical direction, and the second direction is a horizontal direction.
In an embodiment of the present invention, the inclined slide rail 21 is provided with two rails, and the two rails are respectively disposed on two sides of the guide plate 22. The guide plate 22 may be triangular; the cross-section of the punch 3 may comprise an isosceles triangle.
The utility model further discloses a stripping device which comprises an upper template and a lower template 4, wherein the upper template comprises a stripping plate and a sliding block mechanism, and the stripping plate is connected with the sliding block mechanism and used for driving the sliding block mechanism to move along a first direction. Referring to fig. 1 to 4, the slider mechanism includes a driving block 1, a guiding slider 2 and a punch 3, and the punch 3 is disposed at the bottom of one side of the guiding slider 2.
The driving block 1 is provided with an inner cavity 11, and the inner cavity 11 is provided with an inclined guide rail 12; the guide slide block 2 is provided with an oblique slide rail 21, and the oblique slide rail 21 is embedded with the oblique guide rail 12 of the driving block 1. A guide groove 13 is formed in the driving block 1, and a guide plate 22 is arranged on the guide sliding block 2; the guide plate 22 can slide along the guide groove 13 and plays a guiding role when the driving block 1 and the guide slide block 2 move relatively.
When the driving block 1 and the guide slider 2 are in a first posture and the movement of the guide slider 2 in the first direction is limited (as shown in fig. 3, the guide slider 2 is located on the lower template 4 at this time), the driving block 1 and the guide slider 2 generate relative motion, and the driving block 1 slides along the inclined slide rail 21 of the guide slider 2 through the inclined guide rail 12; so that the movement of the driving block 1 along the first direction generates the movement of the guide slide block 2 along the second direction, and further drives the punch to move along the second direction; the first direction is perpendicular to the second direction. In an embodiment, the first direction is a vertical direction, and the second direction is a horizontal direction.
Referring to fig. 2, in a usage scenario of the present invention, when the sliding block mechanism (or called as a transverse mechanism) is under a set pressure, the driving block is fixed to the stripper plate and moves up and down along with the stripper plate, and the inner cavity is provided with an inclined guide rail.
The slide rail of the guide slide block is embedded with the oblique guide rail of the driving block, so that the vertical motion of the driving block is converted into horizontal motion, and the fixing and guiding effects on the punch are achieved. The mechanism can realize the functions of guiding, stripping, limiting, synchronizing (realizing transverse processing while moving downwards) and the like.
The driving block is driven by the stripper plate to drive the guide slide block to move downwards through the sliding guide rail of the driving block, no relative motion exists between the driving block and the guide slide block before the guide slide block contacts the lower template, and when the guide slide block moves downwards to contact the lower template, the driving block still moves downwards until the driving block contacts the lower template, and the driving block stops moving when reaching the displacement limit.
The guide slide block makes different two-dimensional motions in stages, the guide slide block keeps a state of extending out of the driving block downwards in an initial state, and the extending length is determined by the required stroke. Before the guide sliding block contacts the lower template, no relative motion exists between the driving block and the guide sliding block, when the guide sliding block moves downwards to contact the lower template, the driving block still moves downwards until the driving block contacts the lower template, the guide sliding block stops moving downwards to change into horizontal motion along with the downward movement of the driving block, the process is finished until the driving block contacts the lower template to reach the displacement limit, and the guide sliding block is completely retracted into the driving block.
The punch is arranged on the guide sliding block and moves along with the guide sliding block, the upper surface of the punch is in contact with the workpiece during return stroke, the guide sliding block is limited to move upwards along with the drive block when the drive block moves upwards, and therefore the relative movement of the drive block and the guide sliding block is kept, and the punch generates transverse movement and exits the workpiece. The straightness of the transverse movement is ensured by the matching of the guide slide rail and the guide rail of the driving block, and the left and right lateral limits are provided by the limit blocks of the guide rail of the driving block and the movement bottom dead center of the driving block.
In a usage scenario of the present invention, the working process of the stripper plate slider mechanism of the present invention comprises: the punch head and the guide slide block assembly do transverse movement relative to the driving block, and the punch head extends out of the guide slide block along with the movement progress of the guide slide block and is inserted into a workpiece. In the process, the lifting pin is driven to drive the workpiece to be static or move by the downward driving force of the stripper plate, so that the coordination of the positions of the punch and the workpiece during insertion and separation is ensured.
In conclusion, the stripper plate sliding block mechanism and the stripper device provided by the utility model can obtain a stable and reliable bending shape.
