Description

Technical Field

[0001] The utility model relates to the technical field of inclined wedge hidden punching of stamping dies, in particular to an inclined wedge hidden punching structure of a progressive die for reinforcement plates. Background Technique

[0002] When producing parts such as reinforcement plates in automotive lighting industrial products, it is necessary to utilize the cooperation between the inclined wedge and the slider in the inclined wedge hidden punching structure to convert the vertical movement in the stamping die into horizontal movement or inclined movement to achieve the stamping forming of the sheet metal. Most traditional inclined wedge hidden punching structures consist of a carrier plate, a slider, an inclined wedge, a pressure plate that cooperates with the carrier plate for stamping forming, and a slider located below the pressure plate. Usually, the slider is the force-receiving body, and the inclined surface on the slider contacts the inclined surface of the inclined wedge. Under the push of the inclined wedge, the slider moves along the inclined surface to stamp the sheet metal, which has the effects of improving the production efficiency of parts such as reinforcement plates and improving the stamping accuracy of products. However, when the slider and the inclined wedge on the traditional inclined wedge hidden punching structure cooperate and slide, there is no component for limiting the sliding, resulting in the problem that when the pressure plate presses down and the inclined surface of the inclined wedge slides along the inclined surface of the slider, if the pressure or the degree of pressure received is uneven, there will be a deviation in the sliding direction of the cooperation between the inclined wedge and the slider.

[0003] Therefore, the utility model provides an inclined wedge hidden punching structure of a progressive die for reinforcement plates. Content of the Utility Model

[0004] The purpose of the utility model is to provide an inclined wedge hidden punching structure of a progressive die for reinforcement plates to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] An inclined wedge hidden punching structure of a progressive die for reinforcement plates, including a bearing plate, a slider arranged on the bearing plate, and an inclined wedge assembly cooperating with the slider. A guiding groove is arranged on the outer side of the lower inclined surface of the slider, and a guiding rib with an inclination angle consistent with that of the inclined surface is arranged on the outer side surface of the guiding groove;

[0007] The inclined wedge assembly includes a pressure plate connecting block and an inclined block connected to the pressure plate connecting block. A guiding plate is arranged on the side of the inclined block Y corresponding to the guiding groove, and a limiting strip for cooperating with and limiting the guiding rib is arranged at the end of the guiding plate. The inclined block guides the inclined sliding of the inclined wedge assembly and the slider through the cooperation of the guiding plate and the guiding strip with the guiding groove and the guiding rib.

[0008] Furthermore, the lower inclined surface of the slider is set in an inwardly concave trapezoidal shape, and the upper inclined surface of the inclined block is set in a convex trapezoidal shape. The upper inclined surface of the inclined block is embedded in the lower inclined surface to cooperate with the inclined movement of the inclined block and the slider, and the upper inclined surface on the inclined surface is embedded in the lower inclined surface of the slider, so that the upper inclined surface of the inclined block is confined in the lower inclined surface of the slider. When the pressure plate moves downward with the operation of the stamping equipment, the inclined block on the inclined wedge assembly is guided along the inclined cooperation of the lower inclined surface and the upper inclined surface, keeping the pressure plate tilted and moving downward stably, thereby achieving the effect of improving the stability of the tilting downward movement of the pressure plate.

[0009] Furthermore, an I-shaped assembly block is provided on the top surface of the inclined block, and a sliding groove is provided on the bottom surface of the pressure plate connecting block for sliding assembly with the assembly block. The assembly block is embedded in the sliding groove and cooperates with the inclined block and the pressure plate connecting block for sliding assembly. The inclined block is assembled in a detachable form with the assembly block and the pressure plate connecting block. When the inclined block and the slider reciprocate and slide to produce products, wear occurs, resulting in a gap deviation between the upper inclined surface of the inclined block and the lower inclined surface of the slider. The inclined block can be removed from the pressure plate connecting block and replaced with a new one, thereby reducing the cost of replacing mold accessories.

[0010] Furthermore, the pressure plate connecting block is provided with four through holes for matching the pressure plate connecting block with the pressure plate installation, and the pressure plate connecting block is fixed to the pressure plate after bolts penetrate through the through holes, so that the inclined wedge assembly and the pressure plate are fixed in a detachable form.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The inclined wedge blind punching structure of the reinforcing plate step-in die is provided with a guide plate with a guide convex strip on the inclined block on the inclined wedge assembly, and a guide groove and a limit strip are provided on the lower inclined side of the slider to cooperate with the guide convex strip and the guide plate for guidance. When the inclined wedge assembly moves downward with the pressure plate above the bearing plate, the guide plate and the limit strip on the side of the inclined block on the inclined wedge assembly are restricted in the limit groove, so that the inclined wedge assembly and the slider can cooperate to stably tilt downward, thereby improving the precision of the inclined wedge blind punching structure for the stamping forming of the product;

[0013] The inclined wedge assembly is detachably assembled from a pressure plate connecting block and an inclined block. The inclined block is detachably assembled with the pressure plate connecting block through an assembly block. When the inclined block and the slider slide back and forth to produce products, wear occurs, causing a gap deviation to occur between the upper inclined surface of the inclined block and the lower inclined surface of the slider. The inclined block can be removed from the pressure plate connecting block and replaced with a new one, thereby reducing the cost of replacing mold accessories. BRIEF DESCRIPTION OF THE DRAWINGS

A guiding plate 8 is provided on one side of the inclined block 7 corresponding to the guiding groove 4, and a limiting strip 9 cooperating with the guiding rib 5 for limiting is provided at the end of the guiding plate 8. The inclined block 7 cooperates with the guiding groove 4 and the guiding rib 5 through the guiding plate 8 and the guiding strip to guide the inclined sliding of the inclined wedge assembly 3 and the slider 2.

[0024] The lower inclined surface 10 of the slider 2 is arranged in a concave trapezoid shape, and the upper inclined surface 11 of the inclined block 7 is arranged in a convex trapezoid shape. The upper inclined surface 11 of the inclined block 7 is embedded in the lower inclined surface 10 to cooperate with the inclined movement of the inclined block 7 and the slider 2. The upper inclined surface 11 on the inclined surface is embedded in the lower inclined surface 10 of the slider 2, so that the upper inclined surface 11 of the inclined block 7 is limited in the lower inclined surface 10 of the slider 2. When the pressure plate moves downward with the operation of the stamping equipment, the inclined block 7 on the inclined wedge assembly 3 is guided by the inclined cooperation of the lower inclined surface 10 and the upper inclined surface 11, keeping the pressure plate moving downward stably in an inclined manner, converting the vertical movement when the pressure plate moves downward into a horizontal movement or an inclined movement towards the position of the bearing plate 1, enabling the mold to realize continuous and automated production of parts such as reinforcing plates, thereby improving production efficiency, and achieving the effects of improving the stability of the inclined downward movement of the pressure plate, improving the dimensional accuracy and shape accuracy of the product.

[0025] The top surface of the inclined block 7 is provided with an I-shaped assembly block 12. The bottom surface of the pressure plate connecting block 6 is provided with a sliding groove 13 that cooperates with the assembly block 12 for sliding assembly.

When the inclined block 7 and the slider 2 reciprocally cooperate and slide to produce products and wear occurs, resulting in a gap deviation in the docking between the upper inclined surface 11 of the inclined block 7 and the lower inclined surface 10 on the slider 2, the inclined block 7 can be disassembled from the pressure plate connecting block 6 and a new inclined block 7 can be replaced, thereby reducing the cost of replacing accessories for the mold.

[0026] The pressure plate connecting block 6 is provided with four through holes 14 for cooperating with the pressure plate connecting block 6 and the installation of the pressure plate.

A guide groove 4 and a limiting strip 9 that cooperate with the guide rib 5 and the guide plate 8 are arranged on the side of the lower inclined surface 10 of the slider 2. During the downward movement of the pressure plate above the bearing plate 1 with the inclined wedge assembly 3, since the guide plate 8 and the limiting strip 9 on the side of the inclined block 7 of the inclined wedge assembly 3 are restricted in the limiting groove, the purpose of the stable inclined downward movement of the inclined wedge assembly 3 and the slider 2 is achieved, converting the vertical movement when the pressure plate moves downward into a horizontal movement or an inclined movement towards the position of the bearing plate 1, enabling the mold to realize continuous and automated production of parts such as reinforcing plates, thereby improving production efficiency, and achieving the effects of improving the stability of the inclined downward movement of the pressure plate, improving the dimensional accuracy and shape accuracy of the product;

[0028] The wedge assembly 3 is detachably assembled by the pressure plate connection block 6 and the wedge block 7. The wedge block 7 is detachably assembled with the pressure plate connection block 6 through the assembly block 12. When the wedge block 7 and the slider 2 reciprocally cooperate and slide to produce products, wear occurs, resulting in a gap deviation in the docking between the upper inclined surface 11 of the wedge block 7 and the lower inclined surface 10 of the slider 2. The wedge block 7 can be disassembled from the pressure plate connection block 6 and a new wedge block 7 can be replaced, thereby reducing the cost of replacing accessories for the mold.
