The model is time-consuming, difficult to locate, unable to meet customer requirements, and greatly reduces production efficiency.

Utility model content

In view of the above-mentioned existing problems, the applicant made researches and improvements, and provided a mold structure for forming the left and right ribs. This forming mode greatly saves the processing time, has precise positioning, and effectively meets the requirements of customers.

The technical scheme adopted in the utility model is as follows:

A mold structure for forming left and right ribs, comprising a wedge-fixed upper mold and a die, a first wedge and a pair of second wedges are respectively installed in the wedge-fixed upper mold, and a pair of second wedges are installed on the wedge-fixed upper mold The bottom of the fixed upper mold is fixedly connected with the supporting punch used for matching with the product, and punch through holes are opened at both ends of the supporting punch, and a pair of forming punches are arranged on the bottom of the supporting punch. On the step surface, one end of each forming punch extends into the through hole of the punch; a pair of first inclined surfaces are set at the end of the first inclined wedge, and one end of the forming punch does not extend into the through hole of the punch A second slope for matching the first slope is provided.

Its further technical scheme is:

The pair of second oblique wedges are symmetrically arranged around the first oblique wedge;

Each first slope is symmetrically arranged around the axis of the first wedge;

The angle range formed between the first slope of the first wedge and the vertical line is 15±5°, and the angle range between the second slope and the vertical line set on the forming punch is also 15±5°. 5°.

The beneficial effects of the utility model are as follows:

The utility model is simple in structure and easy to use. The utility model can be used to complete the stamping of the left and right ribs inside the product at one time. It has the advantages of high degree of automation and precise positioning, which greatly saves processing time and improves processing efficiency.

detailed description

The specific embodiment of the present utility model is described below.

As shown in Figures 1 to 3, a mold structure for forming left and right ribs includes a wedge-fixed upper mold 3 and a die 8, and a first wedge 2 and a pair of wedges are respectively installed in the wedge-fixed upper mold 3 The second oblique wedge 4, a pair of second oblique wedges 4 are arranged symmetrically with the first oblique wedge 2 as the center. The support punch 6 used to cooperate with the product 7 is affixed to the bottom of the wedge-fixed upper die 3, punch through holes 601 are provided at both ends of the support punch 6, and a pair of forming punches 5 are arranged on On the step surface of the supporting punch 6 , one end of each forming punch 5 extends into the through hole 601 of the punch, and one end of the forming punch 5 extending into the through hole 601 of the punch forms an arc portion 501 . A pair of first slopes 201 are provided at the end of the first wedge 2, and a second slope 502 for matching the first slopes 201 is provided at the end of the forming punch 5 that does not extend into the through hole 601 of the punch. Each first slope 201 is symmetrically arranged around the axis of the first wedge 2 . The angle range formed between the first slope 201 of the above-mentioned first wedge 2 and the vertical line is 15 ± 5 °, and the angle range between the second slope 502 and the vertical line provided on the forming punch 5 is also 15°. ±5°.

Concrete work process of the present utility model is as follows:

As shown in Figures 1 to 3, firstly, the product 7 of the left and right reinforcing ribs 701 to be processed is matched with the supporting punch 6, and the slider 1 of the press moves downward. During the downward process, the first wedge 2 and the second wedge 4 is also moved downward by the action of the slider 1 of the press, and the first wedge 2 slides on the second inclined surface 502 of the forming punch 5 through the first inclined surface 201 during the downward process, and the forming punches 5 are respectively Moving outward in the horizontal direction, the arc portion 501 of the forming punch 5 contacts the inner wall of the product 7 and continues to pressurize it to form an outwardly protruding rib 701. When the slider 1 of the press moves down to the limit position, the first The second wedge 4 enters the wedge matching hole of the die 8, and the supporting punch 6 with the product 7 is also pressed down to the die hole 801 of the die 8, and the rib 701 is formed in the process at the same time. Forming punch 5 is formed. Finally, the press goes up and drives all parts to return to the initial position, and the workpiece is taken out for the next stamping.

The utility model is simple in structure and easy to use. The utility model can be used to complete the stamping of the left and right ribs inside the product at one time. It has the advantages of high degree of automation and precise positioning, which greatly saves processing time and improves processing efficiency.

The above description is an explanation of the utility model, not a limitation of the utility model. For the limited scope of the utility model, refer to the claims. Without violating the basic structure of the utility model, the utility model can be modified in any form.
