Description

Cover punching forming composite mold device

technical field

The utility model relates to the technical field of punching and forming, in particular to a composite mold device for punching and forming of a cover.

Background technique

In the related art, punching and flanging on the same workpiece generally require two processes of punching and flanging. Therefore, two sets of molds are often required, namely the punching mold and the flanging mold. The parts are punched and flanged with two sets of molds respectively. The obvious disadvantage is that the production cost and processing steps of the parts are increased. Moreover, due to the adoption of two processes, the positioning problem is bound to be involved in each process, and the two positionings will inevitably lead to a decrease in the precision of the workpiece processing.

Therefore, it is necessary to provide a new cap punching and forming composite mold device to solve the above technical problems.

Utility model content

The technical problem to be solved by the utility model is to provide a cap punching and forming composite mold device which can be formed at one time and has less stamping process.

The technical scheme of the utility model is as follows:

A cover punching and forming composite mold device, comprising an upper mold part and a lower mold part, the upper mold part includes an upper mold base and a drawing die fixed below the upper mold base, and the lower mold part includes The lower mold base, the drawing punch fixed above the lower mold base and cooperating with the drawing die, and the ejector that is sleeved on the drawing punch and can move up and down along the drawing punch Guide sleeve, the center of the drawing punch is provided with a blanking hole vertically passing through the drawing punch, and the position of the drawing die corresponding to the blanking hole is provided with the blanking hole corresponding to the blanking hole. The punching bump matched with the feed hole.

Preferably, the ejector guide sleeve includes a positioning groove formed by indenting from the surface facing the drawing die toward the direction of the lower die seat.

Compared with the related technology, the cap punching and forming composite mold device provided by the utility model has the following beneficial effects: the punching and flanging of the cap can be completed in the same process at one time, with fewer process steps; The two processes of punching and flanging in the related technology are completed in the mold, which not only saves production costs, but also greatly improves the production efficiency of the cover, and the processing accuracy of the cover is higher.

Description of drawings

In order to more clearly illustrate the technical solutions in the embodiments of the utility model, the accompanying drawings that need to be used in the description of the embodiments will be briefly introduced below. The accompanying drawings in the following description are only some embodiments of the utility model. For Those of ordinary skill in the art can also obtain other drawings based on these drawings without any creative effort, wherein:

Fig. 1 is a structural schematic diagram of a composite mold device for punching and forming a cap of the present invention.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1, the utility model provides a kind of cover punching forming composite mold device 100, comprises upper mold part 1 and lower mold part 2, and described upper mold part 1 comprises upper mold base 10 and is fixed on described upper mold The drawing die 11 below the base 10, the lower die part 2 includes a lower die base 20, a drawing punch 21 fixed above the lower die base 20 and cooperating with the drawing die 11, and a sleeve The ejector guide sleeve 22 is located on the stretching punch 21 and can move up and down along the stretching punch 21 .

The stretching punch 21 is cylindrical, and a blanking hole 210 vertically penetrating through the stretching punch 21 is provided at the center of the stretching punch 21 . The drawing die 11 has a recessed space that matches the shape of the drawing punch 21, and the position of the drawing die 11 corresponding to the blanking hole 210 is provided with a hole that matches the blanking hole 210. Bumping bump 110 .

The ejector guide sleeve 22 includes a positioning groove 220 that is recessed from the surface facing the drawing die 11 toward the lower mold base 20, and the positioning groove 220 is used to accommodate and position the material to be processed. Round sheet metal.

The working principle of the cover punching and forming composite mold device 100 is as follows: the metal sheet to be processed is placed in the positioning groove 220 of the ejector guide sleeve 22, and the upper mold part 1 is lowered. To move in the direction of the lower die part 2, the drawing die 11 pushes the ejector guide sleeve 22 to descend, and the punching bump 110 cuts a through hole in the middle of the metal sheet, and the waste material cut from the metal sheet It is discharged through the blanking hole 210, and the punching process is completed; the drawing die 11 is molded with the drawing punch 21, and the metal sheet is pressed into a cap of the required shape to complete the flanging process; The mold part 1 rises, and the ejector guide sleeve 22 moves along the drawing punch 21 in a direction away from the lower mold base 20, and the ejector guide sleeve 22 lifts up the cover to remove the cover. Mold and place the next sheet metal.

The cover processed by the cover punching and forming composite mold device 100 can be used as the lower cover of the liquid storage tank.

Compared with the related technology, the cap punching and forming composite mold device provided by the utility model has the following beneficial effects: the punching and flanging of the cap can be completed in the same process at one time, with fewer process steps; The two processes of punching and flanging in the related technology are completed in the mold, which not only saves production costs, but also greatly improves the production efficiency of the cover, and the processing accuracy of the cover is higher.

The above descriptions are only examples of the utility model, and are not intended to limit the patent scope of the utility model. Any equivalent structure or equivalent process transformation made by using the utility model specification and accompanying drawings may be directly or indirectly used in other applications. Related technical fields are all included in the patent protection scope of the present utility model in the same way.
