Description

Technical Field

[0001] The utility model relates to the technical field of stamping and forming, in particular to a stamping and forming die. Background Art

[0002] A mold refers to a model or die for making a molded workpiece. It is made of materials such as metal, ceramic, plastic or rubber, and is processed through cutting, processing, and assembly. Stamping is a process that uses a mold to plastically deform a metal sheet under heating to produce a formed part.

[0003] At present, during the process of die stamping, the inventors have found that the machine body will vibrate, causing the stamping parts to have a certain displacement, resulting in errors in the stamping position of the stamping parts. In order to ensure the accuracy of the stamping position, the staff generally adjusts it by hand, but the above method is prone to danger and cause safety accidents. Therefore, we propose a stamping die. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the shortcomings of the prior art, the utility model provides a stamping forming die, which has the advantages of being convenient for pressing and fixing the stamping parts, and there is no need to adjust the position of the stamping parts by hand. It solves the problem of vibration of the machine body and displacement of the stamping parts, which leads to errors in the stamping position of the stamping parts.

[0006] (II) Technical solution

[0007] In order to achieve the above-mentioned purpose of conveniently pressing and fixing the stamping parts without adjusting the position of the stamping parts by hand and preventing the stamping parts from being displaced, the utility model provides the following technical solutions: a stamping forming mold, comprising a base, on which an inverted U-shaped frame is fixedly mounted, a movable structure is provided on the inverted U-shaped frame, a pressing structure is provided on the movable structure, a stamping structure is provided on the inner top wall of the inverted U-shaped frame, part of the structure on the stamping structure is located on the base, and the pressing structure is movably connected to the stamping structure to facilitate pressing and fixing the stamping parts without adjusting the position of the stamping parts by hand and preventing the stamping parts from being displaced.

[0008] As a preferred technical solution of the utility model, a movable hole is opened on the inner side wall of the inverted U-shaped frame, and the inner cavity of the movable hole is movably connected to the movable structure to facilitate the installation of the movable structure.

[0009] As a preferred technical solution of the utility model, the movable structure includes a cylinder, the cylinder is fixedly connected to the outer surface of the inverted U-shaped frame, and the outer surface of the piston rod on the cylinder is movably connected to the inner cavity of the movable hole;

[0010] An inverted L-shaped plate is fixedly installed on one end of the piston rod of the cylinder, and the interior of the inverted L-shaped plate is movably connected to the pressing structure. A limiting rod is arranged inside the inverted L-shaped plate, and one end of the limiting rod is fixedly connected to the inner side wall of the inverted U-shaped frame, and the other end of the limiting rod is fixedly connected to the stamping structure. By placing the stamping part on the stamping structure and then starting the cylinder, the piston rod on the cylinder drives the inverted L-shaped plate to move in the direction of the stamping structure, and the piston rod moves in the inner cavity of the movable hole until the inverted L-shaped plate is moved to contact with the stamping structure. During this period, the inverted L-shaped plate moves along the outer surface of the limiting rod and plays a role of limiting guide, thereby facilitating the pressing structure to move in the direction of the stamping structure, and then facilitating the pressing structure to press the fixed stamping part.

[0011] As a preferred technical solution of the utility model, a limiting hole is opened inside the inverted L-shaped plate, and the inner cavity of the limiting hole is movably connected with the outer surface of the limiting rod. The inverted L-shaped plate moves along the outer surface of the limiting rod and plays a limiting role to facilitate limiting guiding.

[0012] As a preferred technical solution of the utility model, a threaded hole is provided inside the inverted L-shaped plate, and the inner cavity of the threaded hole is movably connected to the pressing structure to facilitate threaded movement of the pressing structure inside the inverted L-shaped plate.

[0013] As a preferred technical solution of the utility model, the pressing structure includes a threaded short rod, the outer surface of the threaded short rod is threadedly connected to the inner cavity of the threaded hole, a rotating block is fixedly installed on one end of the threaded short rod, and a pressing block is fixedly installed on the other end of the threaded short rod. The pressing block and the stamping structure are movably connected through the spiral rotating block. At this time, the rotating block drives the threaded short rod to move along the inner cavity of the threaded hole, and drives the pressing block to move toward the base until the pressing block presses and fixes the stamping part on the stamping structure to prevent displacement due to vibration, thereby facilitating the pressing and fixing of the stamping part, and there is no need to adjust the position of the stamping part by hand, and displacement of the stamping part can be prevented at the same time.

[0014] As a preferred technical solution of the utility model, the stamping structure includes a hydraulic push rod, one end of which is fixedly connected to the inner top wall of the inverted U-shaped frame, and the other end of the hydraulic push rod is fixedly installed with an upper mold. By starting the hydraulic push rod, the hydraulic push rod drives the upper mold to move and move closer to the lower mold to facilitate movement in the direction of the lower mold, thereby completing the stamping.

[0015] As a preferred technical solution of the utility model, the stamping structure also includes a lower mold, which is fixedly connected to the base, and movably connected to the upper mold. The outer surface of the lower mold is fixedly connected to the end of the limit rod away from the inverted U-shaped frame, and the top of the lower mold is movably connected to the pressing block. The upper mold is moved by the hydraulic push rod and moved toward the lower mold until the upper mold completes the stamping of the stamping part fixed by the lower mold. At the same time, the hydraulic push rod drives the upper mold to reset, thereby facilitating the rapid stamping and punching of the stamping parts.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a stamping die, which has the following beneficial effects:

[0018] 1. The stamping forming die is formed by placing the stamping part on the stamping structure and then starting the cylinder. At this time, the piston rod on the cylinder drives the inverted L-shaped plate to move in the direction of the stamping structure, and the piston rod moves in the inner cavity of the movable hole until the inverted L-shaped plate is moved to contact the stamping structure. During this period, the inverted L-shaped plate moves along the outer surface of the limit rod and plays a role in limiting guidance. Then the spiral rotating block is driven by the rotating block. At this time, the rotating block drives the threaded short rod to move along the inner cavity of the threaded hole, and drives the pressing block to move toward the base until the pressing block presses and fixes the stamping part on the stamping structure to prevent displacement due to vibration, thereby facilitating the pressing and fixing of the stamping part, and there is no need to adjust the position of the stamping part by hand, and displacement of the stamping part can be prevented at the same time.

[0019] 2. The stamping die is started by the hydraulic push rod, which drives the upper die to move and move toward the lower die until the upper die completes the stamping of the stamped part fixed on the lower die. At the same time, the hydraulic push rod drives the upper die to reset, so as to facilitate the rapid stamping and punching of the stamped parts. BRIEF DESCRIPTION OF THE DRAWINGS
