[0041] After the backing plate 4 enters the inside of the cavity 2, the height of the adjusting frame 22 is increased, at this time, the upper punch 11 falls, the distance of the upper punch 11 entering the inside of the die body 12 will be changed, thereby changing the die closing height of the middle frame part stamping die set, when producing middle frame parts with different thicknesses or shapes, the accuracy of the stamping process and the consistency of the product quality can be ensured by adjusting the height of the adjusting frame 22, without needing to specially customize a set of die for each specification of product, thereby improving the universality and application range of the die.

[0042] In the embodiment three, on the basis of the embodiment one, the outer wall of the bottom of the die body 12 is fixedly connected with the fixed block 13, the outer wall of the fixed block 13 is movably inserted into the inside of the die frame 1, the outer wall of one side of the fixed block 13 is provided with the insertion slot 54, the insertion slot 54 is movably inserted with the insertion block 53, the outer wall of the rotating shell 5 is rotatably connected with the mounting sleeve 511, the lower inside of the die frame 1 is fixedly connected with the guide rail rod 52, the outer wall of the bottom of the insertion block 53 is provided with the guide rail groove, the inside of the guide rail groove is slidably connected with the outer wall of the guide rail rod 52, the outer wall of the mounting sleeve 511 is fixedly connected with the stress plate 51, and the outer wall of one side of the stress plate 51 is fixedly connected with the outer wall of one side of the insertion block 53.

[0043] The outer wall of the plug 53 is smaller than the inner wall of the slot 54, so that the plug 53 is inserted into the inner wall of the slot 54, and the size of the plug 53 is the same as that of the slot 54, so that the accuracy of the position between the slot 54 and the plug 53 is high, and a one-millimeter gap will affect the insertion of the plug 53 into the inner wall of the slot 54. Correspondingly, the size of the plug 53 is smaller than that of the slot 54, so that the operator can easily insert it into the inner wall of the slot 54, thereby improving the speed of fixing the concave die body 12.

[0044] In example four, on the basis of example three, the inner wall of the slot 54 is provided with a stress hole 66, the inner wall of the plug 53 is movably connected with a moving plate 61, the opposite side of the two moving plates 61 is provided with a track groove 64, the inner wall of the track groove 64 is slidably connected with a push rod 63, the opposite side of the two push rods 63 is fixedly connected with a stress rod 62, the outer wall of the stress rod 62 is movably connected with the inner wall of the plug 53, the inner wall of the plug 53 is movably connected with a moving plate 61, the bottom of the moving plate 61 is a slope, the top of the stress rod 62 is a slope, the outer wall of one end of the stress rod 62 is fixedly connected with a reset spring 65, the outer wall of one end of the reset spring 65 is fixedly connected with the inner wall of the plug 53, and the outer wall of the other end of the stress rod 62 is movably connected with the inner wall of the stress hole 66.

[0045] The moving plate 61 is pushed outward by the push rod 63, and the moving plate 61 is pushed outward by the stress rod 62, so that the moving plate 61 and the moving plate 61 are in contact with the inner wall of the slot 54, thereby filling the gap between the slot 54 and the plug 53, preventing the fixed block 13 from moving, and further increasing the contact between the plug 53 and the slot 54 through the anti-skid pad arranged on the moving plate 61 and the moving plate 61, thereby increasing the stability of the fixed block 13.

[0046] In example five, on the basis of example two, the outer wall of one end of the rotating shaft 55 is fixedly connected with a wire wheel 7 on one side of the bevel gear 43, the outer wall of the wire wheel 7 is fixedly connected with a rope 71, the outer wall of the bottom of the base plate 4 is provided with a mounting groove, the inner wall of the mounting groove is slidably connected with a limiting plate 73, the outer wall of the top of the limiting plate 73 is fixedly connected with a fixed ring 72, the outer wall of the fixed ring 72 is fixedly connected with one end of the rope 71, the outer wall of the top of the limiting plate 73 is fixedly connected with a reset spring 732, the outer wall of the top of the reset spring 732 is fixedly connected with the inner wall of the top of the mounting groove, the lower part of the inner wall of the concave die frame 1 is provided with a limiting groove 731, and the outer wall of the limiting plate 73 is movably connected with the inner wall of the limiting groove 731.

[0047] Loosen by the rope 71, after the base plate 4 moves to the designated position inside the cavity 2, the limiting plate 73 is aligned with the position of the limiting groove 731, at this time, under the action of the reset spring two 732, push the limiting plate 73 into the inside of the limiting groove 731, then the base plate 4 can be limited in the horizontal direction, avoid the adjusting frame 22 is pressed in the inside of the cavity 2 to slide down and contact with the base plate 4, the base plate 4 is impacted and moves, accordingly, increase the stability of the base plate 4, further ensure that the mold height can be stably controlled, improve the precision and reliability of the mold adjustment.

[0048] The working principle and use process of the present application: when working, first, the operator in the present application places the middle frame into the cavity 12, and the middle frame is formed by the downward movement of the upper punch 11, which is the conventional working principle of the middle frame stamping die set, and will not be repeated here.

[0049] In the present application, the operator pushes the limiting convex plate 3 on the supporting rod one 33, and at the same time, the limiting convex plate 3 moves and the reset spring one 35 is extruded to make the reset spring one 35 shorter, so that the limiting convex plate 3 leaves the outer wall of the handle 34, which can release the limiting of the convex on the limiting convex plate 3 on the convex of the handle 34, under the action of the reset spring one 35, when the operator releases the limiting convex plate 3, the limiting convex plate 3 is pushed by the rebound force of the reset spring one 35 to limit the handle 34 again, which avoids the rotation of the handle 34, and accordingly increases the stability of the handle 34.

[0050] In the present application, after the limiting convex plate 3 and the handle 34 are released from the limiting position, the handle 34 can be rotated by the operator, and the handle 34 is prevented from moving forward at the same time by the setting of the baffle 31. Since the handle 34 is fixedly connected with the rotating shell 5, the rotating shell 5 is rotated by the fixedly connected limiting rod 512 on the rotating shell 5 when the handle 34 is rotated. Since the rotating shaft 55 is fixedly connected with the bevel gear two 43, the bevel gear one 42 is rotated by the bevel gear two 43 when the rotating shaft 55 is rotated. Then, the bidirectional screw rod 41 is rotated on the fixed plate by the rotation of the bevel gear one 42. Since the bidirectional screw rod 41 is threadedly connected with the nut 44, the nut 44 drives the pad plate 4 to move in the interior of the recessed die frame 1 when the bidirectional screw rod 41 is rotated. When the pad plate 4 moves to the interior of the cavity 2 and the one end of the pad plate 4 contacts with the inner wall of the cavity 2, the resistance of the handle 34 is increased. At this time, the rotation of the handle 34 is stopped, the pad plate 4 enters the interior of the cavity 2, and the height of the adjusting frame 22 is increased. At this time, the upper punch 11 falls, the distance of the upper punch 11 entering the interior of the recessed die body 12 is changed, and the height of the middle frame part stamping die combined die is changed. When the middle frame parts of different thicknesses or shapes are produced, the accuracy of the stamping process and the consistency of the product quality can be ensured by adjusting the height of the adjusting frame 22. A set of die for each specification of product is not needed, the universality and the application range of the die are improved.

[0051] In the present application, the adjusting frame 22 is lifted by the action of the buffer spring 21 after the upper punch 11 leaves the top of the recessed die frame 1, and the appropriate space between the bottom of the adjusting frame 22 and the inner wall of the cavity 2 is formed, so that the pad plate 4 is provided with convenient conditions for entering or leaving. At the same time, when the upper punch 11 is downwardly pressed and contacts with the adjusting frame 22, the buffer spring 21 plays a buffering role on the adjusting frame 22, the impact force of the upper punch 11 on the adjusting frame 22 is reduced, and the service life of the adjusting frame 22 is increased.

[0052] It should be noted that the buffer spring 21 is internally provided with a damper.

[0053] The fixed connection between the rotating shell 5 and the wire wheel 7 in the application, the wire wheel 7 rotates while the rotating shell 5 drives the bevel gear II 43 to rotate, and then the rope 71 wound on the wire wheel 7 is released through the rotation of the wire wheel 7, and through the relaxation of the rope 71, the limiting plate 73 is aligned with the limiting groove 731 after the base plate 4 moves to the designated position inside the cavity 2, and then the limiting plate 73 is inserted into the limiting groove 731 under the action of the reset spring II 732, so that the base plate 4 can be limited in the horizontal direction, avoiding the base plate 4 from moving when the adjusting frame 22 is pressed and slides downward in the cavity 2 and contacts the base plate 4, and correspondingly increasing the stability of the base plate 4, thereby ensuring that the mold closing height can be stably controlled, and improving the precision and reliability of the mold adjustment.

[0054] It should be noted that the operator can rotate the rotating shaft 55 in the opposite direction to make the wire wheel 7 wind the rope 71, and the limiting plate 73 can be pulled out of the limiting groove 731 through the shortening of the rope 71, so that the limiting of the limiting plate 73 to the base plate 4 is released.

[0055] In the application, the operator pushes the insertion rod 36, and the insertion rod 36 is pushed into the sliding groove II 38 to extrude the push spring 39 while the insertion rod 36 is separated from the inside of the groove 37, so that the contact between the insertion rod 36 and the groove 37 is released to limit the limiting plate 31, and the handle 34 is prevented from sliding in front of the handle 34 through the limiting plate 31, thereby increasing the stability of the handle 34.

[0056] It should be noted that a certain gap is left between the limiting plate 31 and the support frame 32, which is enough for the limiting plate 31 and the support rod I 33 to rotate as the axis.

[0057] In the application, after the limiting of the limiting plate 31 is released, the operator rotates the limiting plate 31, and when the limiting plate 31 rotates above the support rod I 33 as the axis, the handle 34 can be pulled outwards, and then the rotating shell 5 can be moved horizontally through the movement of the handle 34, and at this time, the rotating shaft 55 can be limited through the connection between the support rod II 513 and the rotating shaft 55, so that the rotating shaft 55 does not move horizontally with the rotating shell 5, and because of the connection between the rotating shell 5 and the mounting sleeve 511, the mounting sleeve 511 drives the stress plate 51 to move while the rotating shell 5 moves, and because of the fixed connection between the stress plate 51 and the insertion block 53, the insertion block 53 is separated from the inside of the insertion slot 54 while the stress plate 51 moves, so that the insertion block 53 is fixed to the fixed block 13, and after the fixed block 13 is fixed, the operator pulls the concave mold body 12 upwards to take out the concave mold body 12 from the inside of the concave mold frame 1, so that different models of the concave mold body 12 can be replaced, and the operation is simple and fast, which is convenient for the operator to adjust the middle frame part stamping die set.

[0058] When the operator pushes the rotating shell 5 to drive the insertion block 53 to insert into the interior of the insertion slot 54, the outer wall of the insertion block 53 is smaller than the interior of the insertion slot 54, so that the insertion block 53 is easily inserted into the interior of the insertion slot 54, and the size of the insertion block 53 is the same as that of the insertion slot 54, so that the precision between the insertion slot 54 and the insertion block 53 is high, and a one-millimeter gap will affect the insertion of the insertion block 53 into the interior of the insertion slot 54, and correspondingly, the size of the insertion block 53 is smaller than that of the insertion slot 54, so that the operator can easily insert it into the interior of the insertion slot 54, thereby improving the fixing speed of the concave die body 12.

[0059] After the insertion block 53 is inserted into the interior of the insertion slot 54, the force rod 62 is aligned with the force hole 66, and the insertion block 53 continues to push into the interior of the insertion slot 54, so that the track groove 64 slides on the push rod 63, and the moving plate two 61 slides on the inclined surface of the force rod 62, the track groove 64 is inclined, and when the track groove 64 moves on the push rod 63, the moving plate one 6 is pushed outwards by the push rod 63, and the moving plate two 61 is pushed outwards by the force rod 62, so that the moving plate two 61 and the moving plate one 6 contact the inner wall of the insertion slot 54, thereby filling the gap between the insertion slot 54 and the insertion block 53, preventing the fixed block 13 from moving, and further increasing the contact between the insertion block 53 and the insertion slot 54 by the anti-skid pads arranged on the moving plate one 6 and the moving plate two 61, thereby increasing the stability of the fixed block 13.

[0060] It should be noted that when the insertion block 53 is completely inserted into the interior of the insertion slot 54, the operator cannot continue to push the handle 34 to move, and the baffle 31 is resisted at one end of the handle 34, so that the handle 34 is limited, and the insertion block 53 is stably inserted into the interior of the insertion slot 54.

[0061] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
