Description

Stamping Die Structure for Hanging Cutting of Auto Parts

technical field

The utility model belongs to the technical field of part processing dies, in particular to a structure of a hanging cutting stamping die for automobile parts.

Background technique

Stamping products in existing auto parts need to achieve high strength, and the shape of the product is usually more complicated. At the same time, due to the specific matching relationship, the size tolerance of the workpiece is very small, there is a gap of 0.1cm in the position of the assembly hole, and a gap of 0.2cm in the contour of the special edge. The edge of the product and the position and shape of the hole adopt the traditional trimming and punching process, which requires multiple processes and cannot guarantee the stability of the edge of the part.

Utility model content

The purpose of the utility model is to solve the above-mentioned technical problems, and provide a stamping die structure for hanging and cutting auto parts, so as to realize punching and trimming at the same time, and improve work efficiency. In order to achieve the above object, the utility model technical scheme is as follows:

Hanging cutting stamping die structure for auto parts, including upper base plate, upper template, lower template and hanging cutting assembly; the top of the lower template is provided with a number of positioning blocks for positioning products, and the positioning blocks include protrusions arranged on the lower template The first positioning block on the top and the second positioning block embedded in the lower template, the second positioning block is provided with an arc-shaped convex part extending and connected to the first positioning block, and the hanging cutting assembly includes a The cutter at the bottom of the upper template, the cutter is correspondingly matched with the side profile of the convex part, and the hanging cutting assembly also includes a punch arranged at the bottom of the upper substrate and extending out of the upper template.

Specifically, the auto parts hanging cutting stamping die structure further includes a lower base plate, the lower plate is provided on the top of the lower base plate, and the two side edges of the lower plate are smaller than the two side edges of the lower base plate.

Specifically, a stacked first backing plate and a second backing plate are further provided between the lower template and the lower substrate.

Specifically, the product includes a first protruding part, a second protruding part arranged on one side of the first protruding part, and a special-shaped part connected with the second protruding part, and the bottom of the first protruding part is placed On the first positioning block, the bottom of the second protrusion is placed on the second positioning block.

Specifically, the cutting knife vertically undercuts the first protruding portion and is positioned on a side of the protruding portion.

Specifically, several holes are opened in the special-shaped part, and the punches correspond to the holes.

Compared with the prior art, the beneficial effects of the utility model's hanging-cutting stamping die structure for auto parts are mainly reflected in: trimming and punching are carried out at the same time, which greatly reduces the process flow and improves work efficiency; through the protrusion of the second positioning block The internal positioning matches the cutting knife, and the cutting knife falls accurately, avoiding the cumulative error of multiple positioning and improving product quality.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them.

Example:

Referring to Figures 1-3, the present embodiment is a stamping die structure for hanging and cutting auto parts, including an upper base plate 1, an upper template 11, a lower template 12 and a lower base plate 13, and an edge to be trimmed is arranged between the lower template 12 and the upper template 11. and punched products. The stamping die structure for hang cutting of auto parts also includes a base plate 14 arranged below the lower base plate 13 .

A lower template 12 is provided on the top of the lower substrate 13 , and the two side edges of the lower template 12 are smaller than the two side edges of the lower substrate 13 . A stacked first backing plate 15 and a second backing plate 16 are also provided between the lower template 12 and the lower substrate 13 .

The top of the lower template 12 is provided with several positioning blocks. The positioning block includes a first positioning block 2 protruding from the top of the lower formwork 12 and a second positioning block 21 embedded in the lower formwork 12 . The side of the second positioning block 21 is provided with an arc-shaped protrusion 22 extending and connected to the first positioning block 2 .

The bottom of the upper template 11 is provided with a number of hanging cutting components, the hanging cutting components include a cutter 3 located at the bottom of the upper template 11, and the cutter 3 is matched with the side profiling of the convex portion 22 correspondingly. The hanging cutting assembly also includes a punch (not shown in the figure) which is arranged at the bottom of the upper base plate 1 and extends out of the upper template 11 .

The product is a strip-shaped piece to be stamped, including a first protruding portion 4 , a second protruding portion 41 disposed on one side of the first protruding portion 4 , and a special-shaped portion 42 connected to the second protruding portion 41 . The bottom of the first protruding portion 4 is placed on the first positioning block 2, the bottom of the second protruding portion 41 is placed on the second positioning block 21, and the cutting knife 3 vertically cuts the first protruding portion 4 and is positioned on the protruding portion. 22 sides. A plurality of holes 43 are opened in the special-shaped part 42 , and the punches correspond to the holes 43 .

When applying this embodiment, the product is placed on the positioning block of the lower template 12, and the upper template 11 and the upper substrate 1 are simultaneously pressed down to drive the cutter 3 and the punch to complete the trimming of the first protruding part 4 and the special-shaped part 42 punching. In this embodiment, trimming and punching are carried out at the same time, which greatly reduces the process flow and improves work efficiency; through the positioning of the convex part 22 of the second positioning block 21 to match the cutting knife 3, the landing point of the cutting knife 3 is accurate, avoiding the accumulation of multiple positioning errors and improve product quality.

What have been described above are only some embodiments of the present utility model. For those skilled in the art, without departing from the inventive concept of the present utility model, some modifications and improvements can be made, and these all belong to the protection scope of the present utility model.
