The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0020] First embodiment:

[0021] See also Figures 1 to 4 ,in Figure 1 This is the overall structural diagram of the rear side panel connecting plate drawing die. Figure 2 It is a schematic diagram of the structure of the positioning component. Figure 3 yes Figure 2 A magnified image of Figure 4 It is a schematic diagram of the installation structure of the lifting seat.

[0022] The utility model provides a rear side panel connecting plate drawing die, including a frame 101, a hydraulic cylinder 102, a punch 103, a die 104, a clamping assembly 105 and a positioning assembly 106, wherein the positioning assembly 106 includes a bottom plate 107, a positioning seat 108, a compression spring 109, a lifting seat 110 and a locking member 111, wherein the locking member 111 includes a reset spring 112, a locking seat 113, a plate body 116 and a driving seat 117, and the locking seat 113 includes a seat body 114 and a roller 116. 15. The workpiece is positioned by the positioning seat 108. The compression spring 109 is extended and retracted to allow the bottom plate 107 and the positioning seat 108 to descend, thereby allowing the positioning seat 108 to be received in the die 104 to avoid interference with the drawing of the workpiece. It can be understood that the aforementioned scheme can be used to position the workpiece, and can also be used to lock the positioning seat 108 so that the positioning seat 108 is received in the die 104, which is convenient for taking out the processed workpiece.

[0023] According to this specific embodiment, the hydraulic cylinder 102 is installed on the frame 101, the punch 103 is installed on the output end of the hydraulic cylinder 102, the die 104 is installed on the frame 101, and the clamping assembly 105 is arranged on the punch 103. When in use, the workpiece is placed on the die 104, and the hydraulic cylinder 102 is started to drive the punch 103 to descend, so that the punch 103 extends into the inside of the die 104, thereby drawing the workpiece. During the drawing process, the edge of the workpiece is pressed against the upper surface of the die 104 by the clamping assembly 105, thereby preventing the workpiece from shifting during the drawing process.

[0024] Among them, the bottom plate 107 is slidably connected to the die 104 and is located inside the die 104, the positioning seat 108 is fixedly connected to the bottom plate 107 and is located on the side of the bottom plate 107 close to the punch 103, the two ends of the compression spring 109 are respectively connected to the bottom plate 107 and the die 104, the compression spring 109 is located inside the die 104, the lifting seat 110 is fixedly connected to the bottom plate 107 and is located on the side of the bottom plate 107 close to the compression spring 109, the locking member 111 is arranged on the lifting seat 110, the positioning assembly 106 is provided with four, and is respectively located at the four corners of the die 104, the four corners of the workpiece are positioned by the four positioning seats 108, so that the workpiece can be positioned when placed to avoid the workpiece from being offset when placed, and the compression spring 109 can be extended and retracted. When the punch 103 drives the clamping assembly 105 to descend, the clamping assembly 105 first abuts against the positioning seat 108. Through the extension and retraction of the compression spring 109, the positioning seat 108 can be retracted into the die 104, thereby preventing the positioning rod from interfering with the clamping assembly 105 from clamping the workpiece. When the clamping seat descends, it drives the lifting seat 110 to descend, and the lifting seat 110 is locked by the locking member 111, and then the positioning seat 108 is locked, so that the positioning seat 108 can be locked inside the die 104. At this time, after the punch 103 rises, the positioning seat 108 will not be reset under the action of the compression spring 109, so that the formed workpiece can be taken out, thereby realizing the positioning of the workpiece and avoiding the displacement of the workpiece placement position, which affects the processing purpose.

[0025] Secondly, the reset spring 112 is connected to the lifting seat 110 and is located inside the lifting seat 110; the locking seat 113 is connected to the reset spring 112 and is located at one end of the reset spring 112. A locking groove 118 is also provided on the die 104. When the clamping assembly 105 is pressed on the positioning seat 108, the positioning seat 108 descends and drives the base plate 107 and the lifting seat 110 to descend, so that the lifting seat 110 drives the locking seat 113 to descend. When the locking seat 113 is aligned with the locking groove 118, the locking seat 113 extends into the locking groove 118 under the elasticity of the reset spring 112, thereby locking the lifting seat 110, thereby locking the base plate 107 and the positioning seat 108 inside the die 104.

[0026] At the same time, the seat body 114 is connected to the return spring 112 and is located at one end of the return spring 112; the roller 115 is rotatably connected to the seat body 114 and is located on one side of the seat body 114. The rotation of the roller 115 reduces the friction between the locking seat 113 and the die 104, thereby avoiding wear of the locking seat 113 and the die 104.

[0027] In addition, the driving seat 117 is slidably connected to the die 104 and is arranged on the die 104; the plate body 116 is fixedly connected to the driving seat 117 and is located on one side of the driving seat 117. Two plate bodies 116 are provided and are respectively located on the left and right sides of the die 104. Two driving seats 117 are provided on one plate body 116, and the driving seat 117 extends into the locking groove 118. When the workpiece is taken out, the staff pushes the two plate bodies 116 closer to each other, thereby driving the driving seat 117 to move, so that the driving seat 117 pushes the locking seat 113 to move. When the locking seat 113 is received in the lifting seat 110, the lifting seat 110, the bottom plate 107 and the positioning seat 108 can be reset under the action of the compression spring 109, so that the positioning seat 108 can extend out of the die 104 again, which is convenient for positioning the next workpiece.

[0028] When using the rear side panel connecting plate drawing die of the present embodiment, the workpiece is placed on the die 104 and positioned by the four positioning seats 108. Then, the hydraulic cylinder 102 is started to drive the punch 103 to descend, thereby driving the clamping assembly 105 to descend. The edge of the workpiece is clamped by the clamping assembly 105. While clamping, the positioning seat 108 is pressed into the inside of the die 104 to prevent the positioning seat 108 from interfering with the clamping of the workpiece. Then, the workpiece is drawn by the continued descent of the punch 103. After the workpiece is formed, the hydraulic cylinder 102 drives the punch 103 to rise, and the lifting seat 110, the bottom plate 107 and the positioning seat 108 are locked by the locking seat 113, thereby making the locking seat 113 locked in the die 104. At this time, it is convenient for the staff to take out the formed workpiece, thereby realizing the positioning of the workpiece and avoiding the displacement of the workpiece placement position, which affects the processing purpose.

[0029] Second embodiment:

[0030] Based on the first embodiment, please refer to Figure 5 , Figure 5 2 is a schematic diagram of the installation structure of the nitrogen spring of the second embodiment. The clamping assembly 105 of this embodiment includes a nitrogen spring 201 and a pressure ring edge 202 .

[0031] According to this specific embodiment, the nitrogen spring 201 is connected to the die 104 and is arranged on the die 104; the pressure ring edge 202 is connected to the nitrogen spring 201 and is located at one end of the nitrogen spring 201. The nitrogen spring 201 is provided with multiple. When the hydraulic cylinder 102 drives the punch 103 to descend, the punch 103 drives the nitrogen spring 201 and the pressure ring edge 202 to descend, so that the pressure ring edge 202 is first pressed against the edge of the workpiece to avoid the workpiece from shifting. Then the punch 103 continues to descend and closes the mold with the die 104 to draw the workpiece, thereby achieving the compression of the workpiece and avoiding the problem of the workpiece shifting during the processing.
