Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-9 , a progressive die small-space rotary shaping mechanism provided by the present utility model includes a punching machine for stamping and forming workpieces. The punching machine includes a base 101 and a top plate 102. A lifting table 103 is arranged between the base 101 and the top plate 102, and a lifting component for lifting the lifting table 103 is arranged on the top plate 102;

[0026] It should be noted here that: the lifting component is a conventional auxiliary lifting component on the progressive die and is regarded as the prior art in this application, so no further elaboration is made here;

[0027] A bearing table 104 for placing workpieces is fixed at the upper end of the base 101. A punch 105 for punching the placed workpieces is arranged at the lower end of the lifting table 103. A shaping component for shaping the two sides of the workpieces during the stamping process is further arranged on the base 101. There are two groups of shaping components, and the two groups of shaping components are symmetrically arranged on both sides of the bearing table 104. A stripping component for assisting in stripping after stamping is arranged on the bearing table 104;

[0028] The shaping component includes a mounting frame 201 fixed to the upper end of the base 101. A pressing plate 202 for shaping and extruding one side of the stamping workpiece is connected to the mounting frame 201 through a rotating component. A pushing component for pushing the pressing plate 202 is provided at the lower end of the lifting table 103. A reset component for resetting the pressing plate 202 after being pushed is provided on the mounting frame 201;

[0029] It should be noted here that: through the supporting effect of the bearing table 104 and the extruding effect of the punch 105, the workpiece is stamped and formed. During the forming process, the pressed pressing plate 202 moves towards and abuts against one side of the workpiece. Through the abutting and extruding effects of the two pressing plates 202 on the two shaping components against both sides of the workpiece respectively, the two sides of the workpiece during the stamping process are shaped, avoiding the need to add other processes for auxiliary forming due to insufficient space in the progressive die to set up conventional angle wedges, reducing the equipment cost while ensuring the stamping efficiency of the workpiece.

[0030] The rotating component includes a rotating groove 301 opened on the mounting frame 201. A rod-shaped connecting plate 302 is rotatably connected to the rotating groove 301, and the rod-shaped connecting plate 302 is fixed to the pressing plate 202;

[0031] It should be noted here that: through the rotating groove 301 and the rod-shaped connecting plate 302, it is convenient for the rotating operation of the pressed pressing plate 202.

[0032] The pushing component includes a mounting seat 401 fixed to the lower end of the lifting table 103. A positioning groove 402 is opened on the mounting seat 401. A push plate 403 is detachably mounted on the positioning groove 402 through a bolt. An inclined surface 404 for abutting and transmitting with the push plate 403 is opened at the upper end of the pressing plate 202. Both the push plate 403 and the inclined surface 404 are arranged in an inclined state;

[0033] It should be noted here that: during the process of driving the lifting table 103 to descend, the two mounting seats 401 are driven to descend synchronously. During the descending movement of the mounting seat 401, the push plate 403 mounted on the positioning groove 402 abuts against the inclined surface 404 on the pressing plate 202, pushing the pressing plate 202 to move under force.

[0034] The reset component includes a mounting groove opened inside the mounting frame 201. A plurality of mounting cylinders 501 are fixed inside the mounting groove. A push rod 502 is slidably connected to the mounting cylinder 501. One end of the push rod 502 abuts against the lower end of the pressing plate 202. The push rod 502 is installed and connected to the mounting cylinder 501 through a spring;

[0035] It should be noted here that during the process of shaping and sizing the workpiece by extrusion, as the two sets of pressing plates 202 rotate towards both sides of the workpiece, the bottom of the pressing plate 202 presses on the push rod 502, causing the spring inside the mounting cylinder 501 to be deformed under force to generate elastic force. After the sizing process is completed, due to the elastic force of the spring and the pushing force of the push rod 502, the two sets of pressing plates 202 rotate back to their original positions, facilitating subsequent repeated sizing operations.

[0036] Multiple sets of blanking components are evenly distributed on the bearing table 104;

[0037] It should be noted here that through multiple sets of evenly distributed blanking components, the blanking effect is ensured.

[0038] The blanking component includes a sliding hole 601 opened at the upper end of the bearing table 104. An installation cavity is opened inside the bearing table 104. An operating cylinder 602 is fixed inside the installation cavity. A support rod 603 is slidably connected to the operating cylinder 602. One end of the support rod 603 passes through the sliding hole 601 and is located at the upper end of the bearing table 104. The support rod 603 is connected to the operating cylinder 602 through a spring inside the operating cylinder 602;

[0039] It should be noted here that during the stamping process, due to the extrusion of the punch 105 on the workpiece on the bearing table 104, the support rod 603 is pushed to contract towards the inside of the operating cylinder 602, causing the spring inside the operating cylinder 602 to be deformed under force to generate elastic force. Through the elastic force of the spring and the transmission of the support rod 603, it is convenient to assist in the blanking operation of the workpiece from the bearing table 104 after stamping and forming.

[0040] Working principle: During the process of using a stamping machine to perform stamping and forming operations on a workpiece, the workpiece to be stamped and formed is placed on the bearing table 104 of the base 101. After placement, through the lifting component, the lifting table 103 is driven to move downward. During the downward movement of the lifting table 103, the punch 105 abuts against the workpiece on the bearing table 104. During the abutting process, through the supporting effect of the bearing table 104 and the extrusion effect of the punch 105, the workpiece is stamped and formed;

[0041] During the process of driving the lifting table 103 to descend, it drives the two groups of mounting seats 401 to descend synchronously. During the descending movement of the mounting seats 401, the push plate 403 mounted on the positioning groove 402 abuts against the inclined surface 404 on the pressure plate 202, causing the pressure plate 202 to move under force. During the process of the pressure plate 202 being under force, through the rotational connection between the rotation groove 301 and the rod-shaped connecting plate 302, the pressure plate 202 after being under force moves towards and abuts against one side of the workpiece. Through the abutting and squeezing actions of the two pressure plates 202 on the two groups of shaping components against the two sides of the workpiece respectively, the two sides of the workpiece during the stamping process are shaped, avoiding the need to add other processes for auxiliary forming due to insufficient space in the progressive die to set up a conventional inclined wedge, reducing the equipment cost while ensuring the efficiency of the workpiece stamping and forming;

[0042] During the process of forming, extruding and shaping the workpiece, as the two pressure plates 202 rotate towards the two sides of the workpiece, the bottom of the pressure plate 202 squeezes the push rod 502, causing the spring inside the mounting cylinder 501 to be deformed under force to generate elastic force. After the shaping process is completed, through the elastic force of the spring and the pushing action of the push rod 502, the two pressure plates 202 rotate to reset, facilitating subsequent repeated shaping operations. And during the stamping process, through the squeezing action of the punch 105 on the workpiece on the bearing table 104, the support rod 603 is pushed to contract towards the inside of the operating cylinder 602 and the spring inside the operating cylinder 602 is deformed under force to generate elastic force. Through the elastic force of the spring and the transmission of the support rod 603, it facilitates the stripping operation of the workpiece from the bearing table 104 after the auxiliary stamping and forming.
