Specific embodiments

[0024] The following will clearly and completely describe the technical solutions of the embodiments of the present invention in conjunction with the drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts are within the scope protected by the present invention.

[0025] An embodiment of the present invention provides a progressive die for an automotive air-conditioning compressor valve plate, as Figures 1 to 7As shown, the progressive die includes an upper die base 1 and a lower die base 2. The progressive die has a loading side 3 and a discharging side 4. A clamping plate 5 is slidably connected to one side of the upper die base 1 facing the lower die base 2. An insert 6 is arranged on the clamping plate 5, and an upper punch 7 is installed on the insert 6. A turning plate 8 is rotatably connected to the discharging side 4 of the upper die base 1, and one end of the turning plate 8 away from the upper die base 1 is detachably connected to the clamping plate 5.

[0026] Specifically, in this embodiment, when a worker needs to replace or maintain the upper punch 7, first disassemble the turning plate 8 from the clamping plate 5, then rotate the turning plate 8 in a direction away from the upper die base 1 to expose one end of the clamping plate 5 close to the discharging side 4, and then move the clamping plate 5 out from under the upper die base 1. After replacing or maintaining the upper punch 7 on the clamping plate 5, insert the clamping plate 5 back under the upper die base 1, rotate the turning plate 8 in the reverse direction, and fix the turning plate 8 to the clamping plate 5, then the installation can be completed. This reduces the operation steps for disassembling the upper punch 7, makes it more convenient and quick to replace or maintain the upper punch 7, and thus improves the equipment production capacity.

[0027] In a preferred embodiment of the present utility model, a convex platform 9 is provided on the end surface of the turning plate 8 facing the clamping plate 5, and a groove 10 for clamping the convex platform 9 is formed on one side of the clamping plate 5 facing the lower die base 2.

[0028] Specifically, in this embodiment, when one end of the turning plate 8 away from the upper die base 1 rotates to abut against the clamping plate 5, the convex platform 9 of the turning plate 8 is clamped in the groove 10, so as to facilitate the worker to confirm that the turning plate 8 has been rotated to a predetermined position.

[0029] In a preferred embodiment of the present utility model, a slider 11 is fixedly installed on the end surface of the clamping plate 5 facing the upper die base 1, and a sliding groove 12 for slidably clamping the slider 11 is formed on the end surface of the upper die base 1 facing the lower die base 2. One end of the sliding groove 12 penetrates through the discharging side 4 of the upper die base 1.

[0030] Specifically, in this embodiment, the slider 11 is selected to be in a dovetail shape, that is, the outer diameter of the end of the slider 11 connected to the clamping plate 5 is smaller than the outer diameter of the end of the slider 11 away from the clamping plate 5. The shape of the sliding groove 12 matches the dovetail shape. When the clamping plate 5 is inserted under the upper die base 1 along one end of the sliding groove 12 and slides, the clamping plate 5 is not easily dropped from the upper die base 1, and the worker does not need to always hold the clamping plate 5 during the installation process of the clamping plate 5, which is more labor-saving and convenient.

[0031] In a preferred embodiment of the present utility model, one end of the clamping plate 5 close to the discharging side 4 is fixed to one end of the turning plate 8 away from the upper die base 1 by a fastening bolt.

[0032] Specifically, in this embodiment, the fastening bolt is screwed into the turning plate 8 and the clamping plate 5 in sequence to fix the position between the clamping plate 5 and the turning plate 8.

[0033] In a preferred embodiment of the present utility model, the clamping plate 5 is provided with a stepped hole, the insert 6 is inserted into the stepped hole and fixed to the clamping plate 5 by a countersunk head bolt, and the inner diameter of the hole of the stepped hole close to the upper die base 1 is larger than the inner diameter of the hole of the stepped hole close to the lower die base 2.

[0034] In a preferred embodiment of the present utility model, one end of the clamping plate 5 facing the blanking side 4 is provided with a screw hole 14 for screwing in a fastening bolt. A distance sensor 15 is embedded at one end of the clamping plate 5 away from the blanking side 4. A viewing hole 16 for the ray of the distance sensor 15 to emit is provided between the distance sensor 15 and the screw hole 14. The distance sensor 15 is used to collect distance signals and send them to an external controller. The distance signal represents the depth of the fastening bolt screwed into the screw hole 14, and the controller controls the opening and closing of the press according to the distance signal and the opening and closing signal input from the outside.

[0035] Specifically, in this embodiment, the controller presets a depth range. When the depth of the fastening bolt screwed into the screw hole 14 represented by the distance signal does not conform to the depth range, the controller does not perform the start operation even if it receives the start signal of the press input from the outside, avoiding the situation of starting the machine when the clamping plate 5 is not fixed properly; if the distance signal received by the controller indicates that the depth of the fastening bolt screwed into the screw hole 14 conforms to the depth range, after the controller receives the start signal of the press input from the outside, it performs the start operation, ensuring the stable connection between the clamping plate 5 and the turning plate 8 before performing the start operation, improving the production safety.

[0036] In a preferred embodiment of the present utility model, the upper die base 1 is provided with an installation groove 17. A support shaft 18 is arranged in the installation groove 17. One end of the turning plate 8 is sleeved on the support shaft 18 and is rotatably connected to the support shaft 18. A rubber layer 19 is arranged at the end of the turning plate 8 sleeved on the support shaft 18, and the rubber layer 19 abuts against the wall of the installation groove 17.

[0037] Specifically, in this embodiment, the clamping plate 5 is restricted by the cooperation of the slider 11 and the chute 12. When the clamping plate 5 has a tendency to move in the extending direction of the chute 12, since the turning plate 8 can only rotate circumferentially along the axis of the support shaft 18, which is contrary to the moving direction of the clamping plate 5, it plays a role in restricting the movement of the clamping plate 5.

[0038] During the rotation of the turning plate 8, the rubber layer 19 rubs against the wall of the installation groove 17, so that the turning plate 8 is subjected to resistance during rotation. After one end of the turning plate 8 away from the upper die base 1 rotates in the direction away from the lower die base 2 and the worker releases the turning plate 8, the turning plate 8 can still maintain the corresponding posture, facilitating the worker to insert the clamping plate 5 subsequently.

[0039] The installation groove 17 leaves a space margin for the rotation of the turning plate 8.

[0040] In a preferred embodiment of the present utility model, an easy-pull groove 20 is formed at one end of the clamping plate 5 close to the blanking side 4, and a handrail 21 is integrally formed in the easy-pull groove 20.

[0041] Specifically, in this embodiment, after the worker puts his hand into the easy-pull groove 20, the clamping plate 5 can be removed by means of the handrail 21.

[0042] In summary, during daily maintenance of the punch or replacement of the punch style, the worker needs to first control the press to move the upper die holder 1 away from the lower die holder 2, then remove the fastening bolts, and then rotate the turning plate 8 to expose one end of the clamping plate 5 close to the blanking side 4, so that the clamping plate 5 can be removed from the upper die holder 1. After the punch maintenance or punch replacement is completed, the assembled clamping plate 5 is inserted into the chute 12, the turning plate 8 is rotated in the reverse direction, and the turning plate 8 and the clamping plate 5 are fixed with the fastening bolts. The above-mentioned disassembly and assembly method of the clamping plate 5 is simple and convenient, and the worker does not need to remove the upper die holder 1 from the press, thereby improving the efficiency of daily maintenance of the punch or replacement of the punch style.
