Detailed Description

In order that the above objects, features and advantages of the application will be readily understood, a more particular description of the application will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. The present application may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the application, whereby the application is not limited to the specific embodiments disclosed below.

As described in the background art, the related art product stamping forming apparatus has the problems of lower blanking quality and lower product yield, and the inventor has found that the problem arises because, in general, the material strip at the position to be stamped includes a body, on which an annular ring, a portion to be stamped disposed inside the annular ring, and a plurality of connecting strips disposed between the annular ring and the portion to be stamped are disposed, and the portion to be stamped is connected to the annular ring by each connecting strip. When the material belt enters the fine punching position from the position to be punched, the product punching forming device is matched with the forming female die through the forming male die so as to punch and process the product on the part to be punched. The circumferential edge of the part to be punched is connected with the annular ring through the connecting strips, so that the stress of the part to be punched provided with the connecting strips is larger than that of other parts in the process of punching the part to be punched to form a product, namely the whole circumference of the part to be punched is unevenly stressed, the position, corresponding to the connecting strips, on the outer circumferential surface of the product to be punched is provided with a tearing belt bump defect, the bright belt is further inconsistent with the requirement, and the product qualification rate is lower.

Based on the reasons, the application provides a product stamping forming device which can improve the product processing quality, so that the product qualification rate is improved, and the processing efficiency is improved.

Referring to fig. 1, fig. 1 illustrates a schematic structure of a material belt 10 according to an embodiment of the present application, the material belt 10 includes a plurality of manufacturing units 11 sequentially processed by a product press forming apparatus along the F direction, and each manufacturing unit 11 corresponds to a different process. The manufacturing units 11 specifically include, for example, four manufacturing units as shown in fig. 1, and the first manufacturing unit 11 includes an annular ring 111, a portion to be punched 112 provided in the annular ring 111, and a plurality of connecting bars 113 located between the annular ring 111 and the portion to be punched 112, and the portion to be punched 112 is connected to the annular ring 111 through each connecting bar 113. After the first manufacturing unit 11 moves to the precut position along the F direction, the second manufacturing unit 11 is obtained by precutting by the product press forming device, and the second manufacturing unit 11 is different from the first manufacturing unit 11 in that a notch 1131 is formed in at least one connecting bar 113. After the second manufacturing unit 11 moves to the fine blanking position along the direction F, the product stamping forming device performs stamping forming treatment, so that the product 114 and the waste material, namely the third manufacturing unit 11, are formed on the portion to be stamped 112. The third production unit 11 continues to move in direction F and a fourth production unit 11 is obtained, the waste material is completely separated from the product 114, and the product 114 is detached from the fourth production unit 11.

Referring to fig. 1 to 3, fig. 2 and 3 respectively show two different operation states of a product press forming apparatus according to an embodiment of the present application, wherein the product press forming apparatus includes a pre-cutting mechanism 20 and a press forming assembly 30. The pre-cutting mechanism 20 is used for pre-cutting the material tape 10, and the pre-cutting mechanism 20 comprises pre-cutting pieces 21 which are arranged corresponding to the positions of the connecting strips 113 of the material tape 10 and cut to form notches 1131 on the connecting strips 113. The press forming assembly 30 is used for performing press processing on the portion to be pressed 112 of the material tape 10 that is pre-cut by the pre-cutting mechanism 20.

In the above product stamping forming device, in the process of stamping the material belt 10 to form the product 114, the material belt 10 moves through the pre-cutting mechanism 20, and the pre-cutting piece 21 of the pre-cutting mechanism 20 is pressed down to form the notch 1131 on the connecting strip 113, so that the pulling force of the connecting strip 113 on the portion 112 to be stamped in the process of fine stamping forming can be reduced, the stress of each part on the periphery of the portion 112 to be stamped is relatively more uniform, the size of the area of the bright belt on the periphery of the product 114 can be improved, the qualification rate of the product 114 can be improved, and the processing efficiency can be improved.

Referring to fig. 1, in some embodiments, the number of connecting bars 113 on the outer periphery of each portion to be punched 112 on the connecting band may be the same or different, each including but not limited to 2, 3, 4, 5 or other numbers. In order to facilitate the processing efficiency of the pre-cutting mechanism 20, each of the production units 11 on the connecting tape is formed by processing in sequence in the F direction so that the number and positions of the connecting bars 113 on the outer periphery of each portion to be punched 112 are kept uniform.

As an example, the number of pre-cut pieces 21 of the pre-cutting mechanism 20 may be the same as the number of the connection bars 113 of the portion to be punched 112 and arranged correspondingly, so that the notches 1131 can be formed on each connection bar 113 of the portion to be punched 112, referring to fig. 1, the number of pre-cut pieces 21 of the pre-cutting mechanism 20 may be smaller than the number of the connection bars 113 of the portion to be punched 112, and the number of pre-cut pieces 21 of the pre-cutting mechanism 20 may be, for example, 1,2, 3 or other numbers, that is, a part of the connection bars 113 on the portion to be punched 112 are processed to form the notches 1131, and the rest of the connection bars 113 do not need to be processed to form the notches 1131. Specifically, when the pre-cut pieces 21 of the pre-cutting mechanism 20 are arranged, the connection bars 113 to be cut into the notches 1131 are determined according to the parts, such as the exposed parts, of the outer peripheral surface of the product 114, where the appearance quality requirements of the outer peripheral surface of the product 114 are high, that is, the connection bars 113 to be cut into the notches 1131 are arranged corresponding to the parts, such as the exposed parts, of the outer peripheral surface of the product 114, where the appearance quality requirements of the outer peripheral surface of the product 114 are high, and the pre-cut pieces 21 are arranged corresponding to the connection bars 113 to be cut into the notches 1131 according to the requirements.

In some embodiments, the pre-cut 21 includes, but is not limited to, being configured as a cutter, a needle punch, a cutting blade, a cutting plate, etc., provided that the formation of the notch 1131 on the connecting strip 113 is enabled to reduce the pulling force of the connecting strip 113 against the outer periphery of the stamped portion 112 during the fine stamping process.

Referring to fig. 1 to 3, in one embodiment, the punch forming assembly 30 includes a first die holder 31, a forming punch 32 disposed on the first die holder 31, a second die holder 33, and a forming die 34 disposed on the second die holder 33. The molding male die 32 and the molding female die 34 are correspondingly arranged, and the first die holder 31 or the second die holder 33 is used for being connected with a driving mechanism. The drive mechanism includes, but is not limited to, various power mechanisms such as motor lead screw drive, motor crank drive, motor gear drive, cylinder drive, and the like. Optionally, the pre-cutting mechanism 20 is coupled to the first die holder 31 or the second die holder 33. In this way, in the process of processing the product 114 from the portion to be punched 112 at the fine blanking position, the pre-cutting mechanism 20 will synchronously move under the driving of the first die holder 31 or the second die holder 33, so that the connection strip 113 can be pre-cut at the pre-cutting position to form a notch, that is, at least two different processes of the material strip 10 can synchronously work, thus not only simplifying the power-driven structure, reducing the device cost, but also improving the processing efficiency.

Of course, as some alternatives, the pre-cutting mechanism 20 is not connected to the first die holder 31 or the second die holder 33, but is independently arranged and independently driven to perform pre-cutting of the connecting strip 113 of the material belt 10 to form a notch, and after the connecting strip 113 of the material belt 10 is pre-cut to form a notch, the material belt 10 is transferred to a fine blanking position for fine blanking.
