Detailed implementation manners

[0029] Next, the technical solutions of the present invention will be described clearly and completely in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] As Figure 1-6 shown, a screw stamping and forming device includes: a bottom plate 4, a fixed frame 1 in a "U" shape is fixedly connected to the top end of the bottom plate 4, and a plurality of support feet 5 are fixedly connected to the bottom of the bottom plate 4, and the support feet 5 are used to support the entire device.

[0031] A first cylinder 2 is fixedly arranged on the fixed frame 1, and the output end of the first cylinder 2 is fixedly connected with a pressing head 3. Starting the first cylinder 2, the output end of the first cylinder 2 drives the pressing head 3 to move downward to stamp and form the screw body 9, and stamp the screw body 9 into the required shape and size.

[0032] A connecting frame 6 in a "U" shape is fixedly connected to the top of the bottom plate 4. The inner side of the connecting frame 6 is provided with a screw body 9. A notch 61 for the screw body 9 to pass through is opened at the upper end of the connecting frame 6. Clamping mechanisms are arranged on both sides of the inner side of the connecting frame 6 and on both sides of the screw body 9. The two clamping mechanisms cooperate with each other to clamp and fix the screw body 9. Sealing plates 7 are detachably installed on both sides of the connecting frame 6, and the two sealing plates 7 seal both sides of the connecting frame 6.

[0033] Since the screw body 9 is usually heat-treated before stamping, its surface temperature will be very high. The presence of the sealing plate 7 can effectively isolate the high temperature emitted by the screw body 9 and prevent this heat from directly conducting to the outside of the connecting frame 6, thereby reducing the risk that the operator is scalded due to accidentally touching the connecting frame 6.

[0034] The two sealing plates 7 are provided with square grooves on their sides close to each other. A vertical first slide groove 71 and a second slide groove 72 are provided in the grooves. The first slide groove 71 is parallel to the second slide groove 72. A horizontal third slide groove 73 is provided in the grooves. The third slide groove 73 is connected to the second slide groove 72.

[0035] The sealing plate 7 is fixedly connected with a clamping block on the side close to the connecting frame 6, and a clamping groove is provided on the side of the connecting frame 6. The clamping block of the sealing plate 7 is clamped with the clamping groove of the connecting frame 6 to install the sealing plate 7 on both sides of the connecting frame 6.

[0036] The clamping mechanism includes a slider 11, two sliding frames 13, and two clamping blocks 12. The slider 11 is in the shape of an elongated strip. The two sliding frames 13 are slidably connected to the corresponding sealing plate 7. The two sliding frames 13 on the same mechanism are provided with docking grooves on their sides close to each other. The corresponding clamping blocks 12 can be detachably installed in the docking grooves of the two sliding frames 13. The two clamping blocks 12 can be detachably installed on both sides of the slider 11.

[0037] Regarding the specific installation method of the sliding frame 13: a protrusion 131 is fixedly connected to the side of the sliding frame 13, and the two sliding frames 13 of the clamping mechanism at the rear are slidably connected to the first sliding groove 71 on the corresponding sealing plate 7 through the protrusion 131, and the two sliding frames 13 on the clamping mechanism at the front are slidably connected to the second sliding groove 72 and the third sliding groove 73 on the corresponding sealing plate 7 through the protrusion 131.

[0038] There are many ways for the second sliding groove 72 and the third sliding groove 73 to be slidably connected to the sliding frame 13 , and there are public prior arts, so they will not be elaborated again.

[0039] How the clamp block 12 is mounted on the sliding frame 13: the sliding frame 13 is threadedly connected with a screw rod 132, and both the sliding frame 13 and the clamp block 12 are provided with threaded holes for the screw rod 132 to penetrate. The end of the clamp block 12 is docked into the corresponding docking groove of the sliding frame 13, and the screw rod 132 is passed through the threaded holes on the sliding frame 13 and the clamp block 12 in sequence, so as to fix the clamp block 12 on the sliding frame 13.

[0040] Regarding the specific installation method of the clamping block 12 and the slider 11: the side of the clamping block 12 close to the slider 11 is provided with an embedding groove 121, and both sides of the slider 11 are fixedly connected with protrusions 111. The two clamping blocks 12 are respectively fixed on both sides of the slider 11 through the engagement between the embedding groove 121 and the protrusion 111.

[0041] Regarding the specific installation method of the slider 11: a vertical first limiting groove 62 is opened on the inner side of the connecting frame 6 and in front of and behind the screw body 9. The slider 11 of the clamping mechanism at the rear is slidably connected in the first limiting groove 62 at the rear, and the third cylinder 15 is slidably connected in the first limiting groove 62 at the front. The third cylinder 15 can move up and down in the vertical direction together with the screw body 9, and the output end of the third cylinder 15 is fixedly connected to the slider 11 of the clamping mechanism at the front.

[0042] The heated screw body 9 is placed on the inner side of the connection frame 6 through the notch 61 by the clamp, and the third cylinder 15 is started. The output end of the third cylinder 15 drives the front clamping mechanism to push the screw body 9 to the rear clamping mechanism. During this process, the protrusion 131 of the front clamping mechanism slides in the third slide groove 73. When the screw body 9 contacts the arc groove of the clamping block 12 of the rear clamping mechanism, the two clamping mechanisms complete the clamping of the screw body 9, and at this time, the protrusion 131 of the front clamping mechanism slides into the second slide groove 72. The first cylinder 2 is started. The output end of the first cylinder 2 drives the pressure head 3 to move downward to stamp the screw body 9. When the screw body 9 is stamped and moved downward, it drives the two clamping mechanisms to slide downward together. During this process, the protrusion 131 of the front clamping mechanism slides in the second slide groove 72, and the protrusion 131 of the rear clamping mechanism slides in the first slide groove 71.

[0043] It should be noted that: the shape of each clamping block 12 is the same, but the size of the arc groove on each clamping block 12 is different. The arc grooves of different sizes are used to adapt to the corresponding screw body 9.

[0044] After the stamping is completed, in order to reset the two clamping mechanisms: the top of the slider 11 is fixedly connected with a reset spring 14, the top of the reset spring 14 at the rear is fixedly connected to the connecting frame 6, a second limiting groove 63 is opened on the connecting frame 6, and a moving block 17 is slidably connected inside the second limiting groove 63, the top of the reset spring 14 at the front is fixedly connected to the moving block 17, a fourth cylinder 16 is fixedly arranged on the inner side of the connecting frame 6, and the output end of the fourth cylinder 16 is fixedly connected to the moving block 17.

[0045] The fourth cylinder 16 needs to be started at the same time as the third cylinder 15 is started. The output end of the third cylinder 15 drives the front clamping mechanism to push the screw body 9 to the rear clamping mechanism. During this process, the fourth cylinder 16 pushes the moving block 17 to move synchronously with the front clamping mechanism. When the screw body 9 is pressed downward, the two clamping mechanisms slide downward together. During this process, the reset spring 14 is stretched. After the stamping is completed, the corresponding clamping mechanism is reset under the action of the rebound force of the reset spring 14.

[0046] A buffer mechanism 10 is provided at the upper end of the bottom plate 4 and directly below the screw body 9. The buffer mechanism 10 includes a circular block, on which a groove is provided to fit the bottom of the screw body 9, and an elastic member is fixedly connected between the circular block and the bottom plate 4. The elastic member is preferably a spring, and when the screw body 9 is subjected to a punching force, the screw body 9 pushes the circular block downward, and the circular block squeezes the elastic member, and the elastic member buffers the screw body 9.

[0047] Working principle:

[0048] S1: Start the second cylinder 8, and the output end of the second cylinder 8 drives the sealing plate 7 to move away from the connecting frame 6. During this process, the block of the sealing plate 7 is separated from the slot of the connecting frame 6;

[0049] S2: According to the size of the screw body 9, the sliding frame 13 slidably connected to the sealing plate 7 is installed with the clamping block 12 matching the screw body 9, and the sliding frame 13 and the clamping block 12 become a whole; the second cylinder 8 is started again, and the output end of the second cylinder 8 drives the sealing plate 7 to approach the connecting frame 6, and the clamping block of the sealing plate 7 is clamped with the clamping groove of the connecting frame 6, so that the sealing plate 7 is installed on both sides of the connecting frame 6, and at the same time, the embedded groove 121 is clamped with the protrusion 111 so that the two clamping blocks 12 are respectively fixed on both sides of the slider 11;

[0050] S3: Place the heated screw body 9 through the notch 61 on the inner side of the connection frame 6 by a fixture;

[0051] S4: Start the third cylinder 15. The output end of the third cylinder 15 drives the front clamping mechanism to push the screw body 9 toward the rear clamping mechanism. During this process, the protrusion 131 of the front clamping mechanism slides in the third sliding groove 73. When the screw body 9 contacts the arc groove of the clamping block 12 of the rear clamping mechanism, the two clamping mechanisms complete the clamping of the screw body 9.

[0052] S5: Start the first cylinder 2, and the output end of the first cylinder 2 drives the pressing head 3 to move downward to punch and form the screw body 9.

[0053] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
