Description

Technical fields:

[0001] This application relates to the technical field of D-ring processing equipment, and in particular to an integrated automatic receiving device for cutting, punching, and receiving D-rings. Background technology:

[0002] D-rings are named for their resemblance to the letter "D". During forging, flash forms on the outer edge of the ring and in the center of the eye shape, which needs to be removed using a punch press-driven trimming mechanism.

[0003] Our company's Chinese utility model patent application number 202222794788.0—Eye-shaped safety hook tongue punching and cutting composite device—includes an upper slide block, a punching punch, a trimming punch, and a base plate arranged from top to bottom. The upper slide block is fixedly connected to the punching punch, and a trimming die is fitted over the punching punch. The trimming die is fixedly connected to the upper slide block. The base plate is fixedly connected to the trimming punch, and a ejector plate is fitted over the trimming punch. The ejector plate can move vertically. A guide post is fixedly installed on one of the base plate and the upper slide block, and a guide sleeve is fixedly installed on the other of the base plate and the upper slide block. The guide post is fitted inside the guide sleeve and connected by a sliding structure. By setting the guide post and guide sleeve, the upper and lower parts can be assembled into a whole in advance before being connected to the punch press. This reduces the time for separate assembly and calibration, improves the assembly efficiency, reduces the accumulation of installation errors, and improves the installation accuracy.

[0004] This device can cut the burrs on the eye-shaped safety hook tongue. When changing the cutting punch for cutting the burrs on the D-ring, due to the limitation of the D-ring structure, after the punching is completed, the D-ring will move upward with the punching punch. After the ejector core peels off the punching punch, it falls onto the punching machine operating table. It needs to be collected and picked up by workers and then placed in the storage box. The labor intensity is high and there are certain safety hazards. Utility Model Content:

[0005] To solve the above-mentioned technical problems, this utility model provides an integrated automatic receiving device for D-ring cutting and punching. The technical problem it solves is that D-rings that fall onto the operating table require manual handling, which is labor-intensive and poses certain safety hazards.

[0012] Furthermore, a stop bar is fixedly installed on one side of the rotating shaft, and the stop bar is connected to the power component via a sliding structure.

[0013] Furthermore, the spring is a torsion spring, which is sleeved between the sleeve and the rotating shaft.

[0014] Furthermore, the power component is a plate-like structure with curved corners at its edges.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows:

[0022] The D-ring trimming and punching automatic receiving device includes, from top to bottom, a punch press slide 5, a punching punch 11, a trimming punch 2, and a punch press operating table 1. The punch press slide 5 is fixedly connected to the punching punch 11, and the trimming die 7 is fixedly connected to the punch press slide 5. The punching punch 11 is fitted with a vertically sliding ejector core 6, and the ejector core 6 is fitted with the trimming die 7, which is fixedly connected to the punch press slide 5. The trimming punch 2 is located directly below the ejector core 6 and is connected to the punch press operating table 1. The shape of the trimming punch 2 is adapted to the D-ring, and it has an internal D-shaped structure adapted to the punching punch 11. An automatic receiving mechanism is located on one side of the punch press slide 5. The automatic receiving mechanism includes a rotating receiving box, which is connected to the punch press via a rotating structure. Block 5 is fixedly equipped with a power component 3. When the slide block 5 moves down on the punch press, the power component 3 can drive the rotating receiving box to rotate to one side of the punch press. A spring 4 is also provided to drive the rotating receiving box to rotate into the punch press for receiving material. By setting a receiving plate, it is used to catch the D-rings peeled off by the ejector core 6. And by driving the slide block 5 down on the punch press, the power component controls the rotating receiving box to move to one side of the punch press without delaying the deburring of the D-rings. When the slide block 5 moves up on the punch press, the spring drives the rotating receiving box to be located under the punching punch to catch the D-rings. No other power structure is needed, achieving two goals at once. This tooling realizes the combination of multiple processes such as trimming, punching, and unloading. The number of processes increases, but the number of personnel and equipment does not increase. It achieves the purpose of saving equipment power, saving labor costs, improving production efficiency and safety.

[0023] Specifically, the rotary receiving box includes a rotary shaft 9 mounted on one side of the punch press in a rotating structure, a connecting rod 10 mounted on the rotary shaft 9 in a fixed structure, a receiving plate 12 mounted on the connecting rod 10 in a fixed structure, and a sleeve 8 fixedly mounted on one side of the punch press, which is connected to the rotary shaft 9 in a rotating structure.

[0024] It should be noted that in order to drive the rotating receiving box to rotate using the power component 3, a stop bar 13 is fixedly installed on one side of the rotating shaft 9, and the stop bar 13 is connected to the power component 3 in a sliding structure.

[0025] Specifically, spring 4 is a torsion spring, which is sleeved between sleeve 8 and rotating shaft 9, and the torsion of the torsion spring is used to reset rotating shaft 9.

[0026] It should be noted that the power component 3 is a plate-shaped structure with arc-shaped corners at its edges, which achieves the purpose of pushing the stop lever 13 to rotate.

[0027] A guide post 14 and a guide sleeve 15 are provided between the slide block 5 on the punch press and the operating table 1 of the punch press. The guide post 14 and the guide sleeve 15 are connected by a sliding structure. By setting the guide post 14 and the guide sleeve 15, the upper and lower parts are pre-assembled into a whole and then connected to the punch press. This reduces the time for separate assembly and calibration, improves the efficiency of assembly, reduces the accumulation of installation errors, and improves the installation accuracy.

[0028] The working principle and process of this utility model are as follows:

[0029] The forged D-ring with flash is placed on the trimming punch 2. The press is started, and the press flywheel drives the upper component to move downward through the press slide 5. The component descends until the ejector core 6 contacts the flashed D-ring. The ejector core 6 is supported by the D-ring and moves upward. At this time, the trimming die 7 and the punching punch 11 continue to descend, and the ejector plate also moves downward under pressure. At the same time, a gap is set between the trimming die 7 and the trimming punch 2. The two work together to remove the flash from the outside of the D-ring.

[0030] Affected by the upward movement of the ejector core 6, the ejector rod moves upward, the ejector rod pusher moves upward, the pusher moves upward and contacts the punch bar and then descends, the pusher descends and pushes the ejector rod out, the ejector rod pushes the punching punch, there is a gap between the punching punch 11 and the trimming punch 2, the punching punch moves downward and punches off the internal flash of the D-ring, the internal flash falls off after passing through the trimming punch 2, at this time, the ejector plate rebounds under the support of the spring, causing the external flash to separate from the D-ring.

[0031] While pressing down to remove burrs, the slide block 5 on the punch press drives the power component 3 to move downward. The power component 3 uses the stop rod 13 to push the rotating shaft 9 to rotate, thereby pushing the receiving tray 12 to one side of the punch press.

[0032] After the burrs are removed, the slider 5 on the punch press is moved upward. At this time, the D-ring is stuck outside the punching head 11. As it moves upward, the D-ring is subjected to the pressure of the ejector core 6 and gradually peels off.

[0033] As the slide block 5 on the punch press rises, the rotating shaft 9 gradually rotates under the torque of the torsion spring, which in turn drives the receiving plate 12 to rotate to the lower part of the ejector core 6 via the connecting rod 10, catching the stripped D-ring and completing the operation.

[0034] When the slide block 5 of the punch press descends, the outer edge of the power component 3 pushes the stop rod 13, which in turn drives the rotating shaft 9 to rotate inside the sleeve 8, causing the D-shaped ring of the receiving plate 12 to fall into the storage box, thus completing the edge cutting and material receiving work.
