Description

Technical Field

[0001] The utility model belongs to the technical field of material retrieving clamps, and in particular relates to an internally supported material retrieving clamp. Background Art

[0002] Forging is a combination of forging and stamping. It is a forming process that uses the hammer, anvil, punch of a forging machine or a die to apply pressure to the blank to cause it to undergo plastic deformation, thereby obtaining a part of the desired shape and size. For example, in the forging process of cylindrical products, the heated metal blank needs to be placed between the stamping equipment or the die. By applying pressure, the metal blank undergoes obvious plastic deformation in the die. After maintaining the above operation for a period of time, the pressure is stopped. At this time, the temperature of the metal blank drops and it begins to solidify and take shape. At this time, the finished product can be removed from the die.

[0003] Considering that there is necessary contact between the mold and the metal blank, the metal blank will continue to be embedded in the mold, making it difficult to demold the two. In addition, the metal blank is still at a relatively high temperature, making it inconvenient for manual operation. Therefore, an internal support material removal fixture is designed.

[0023] Example 2

[0024] like Figures 1 to 6The shown embodiment is an internally supported material removal fixture, comprising an operating platform 1 and a working arm 2. The operating platform 1 is provided with a control panel, and can be operated by remotely operating the working arm 2. The working arm 2 is provided with multiple hinge points and is pushed by a cylinder, thereby driving the fixture to achieve multi-directional and multi-angle rotation, suitable for removing blanks at different positions. The end of the working arm 2 is hinged with a connecting block 3, which is also driven by a cylinder, driving itself to rotate at the hinge point of the working arm 2 to achieve rotation in the vertical state; a telescopic cylinder 4 is provided for rotation in the connecting block 3, and the rotation of the telescopic cylinder 4 is controlled by the operating table 1, and then the rotation of the telescopic cylinder 4 can drive the telescopic rod 5, the rotating member 6 and other components installed thereon to rotate; the telescopic rod 5 is slidably arranged in the telescopic cylinder 4, and the rotating member 6 is installed at the bottom of the telescopic rod 5, and the rotating member 6 includes a hinge 61, a support leg 62 and a connecting ring 63. The specific installation arrangement is: a hinge 61 is installed at the bottom of the telescopic rod 5, and the hinge 61 is triangular, and the support legs 62 are hinged in the two corners of the bottom, and the support legs 62 are hingedly connected with a connecting ring 63, wherein the "hinged connection" is specifically presented as the connecting ring 63 being able to move up and down between the support legs 62.

[0025] The above settings are all designed to prevent manual operation from being too close to the blank. The blank still has a high temperature and is prone to burns and other personal injury accidents. Therefore, the staff only needs to stand at the operating table 1 and operate the working arm 2 to ensure that the blank is removed by the removal tool while maintaining the contact distance between the blank and the human body.

[0026] A working chamber 7 is provided at a position below the carrying member 6. The working chamber 7 is opened downward to form a chamber for accommodating and slidably mounting the slide 9. In order to prevent the slide 9 from rotating during the period of sliding up and down in the working chamber 7, which affects the removal action, guide rails 18 are symmetrically provided on the outside of the working chamber 7, and corresponding guide rods 17 are symmetrically provided on the outside of the upper part of the slide 9. When the guide rod 17 slides in the guide rail 18, it can indirectly drive the slide 9 to move vertically up and down in the working chamber 7, thereby ensuring stable operation. The slide 9 has a plurality of slide grooves 10 at the bottom, and a rotating shaft 11 is provided on both sides of the slide groove 10 on the slide 9. A hook 12 is provided on the rotating shaft 11, that is, the hook 12 can rotate in the slide groove 10. The folding angle of the hook 12 is in the shape of an inverted " / ", and the folding angle is relatively rounded. When the upper part of the hook 12 is connected by an elastic rope 13, the elasticity of the elastic rope 13 will make the lower part of the hook 12 maintain an open state. The length of the open diameter here will be greater than the inner diameter of the blank, thereby When the hook 12 moves downward and contacts the inner wall of the blank, the lower part of the hook 12 will be forced to move inward and rotate around the rotating shaft 11, driving the upper part of the hook 12 to move outward and open. At this time, the elastic rope 13 is stretched; the hook 12 continues to move downward, driving the folded corner to move to the bottom of the blank. At this time, the folded corner is no longer under force and is driven by the contraction and reset force of the elastic rope 13 to rotate and reset. At this time, the lower part of the hook 12 returns to the open state, and the folded corner clamps the bottom of the blank. In this way, it can be pushed out. First, fix the relative position of the slide 9 and the working chamber 7, and fix the guide rod 17 in the middle and lower position of the guide rail 18. When the working chamber 7 moves downward, it can drive the slide 9 and the hook 12 inside it to move downward. After the hook 12 clamps the blank, it rests against the working chamber 7 and is fixed on the mold. Then move the slide 9 upward, driving the hook 12 to move upward in the slide groove 10. At the same time, the blank is brought into the working chamber 7 through the hook 12, and then the working chamber 7 is moved. This not only completes the demoulding of the blank, but also prevents the blank from being directly exposed during the demoulding movement and scalding others.

[0027] Next, this embodiment not only solves the problem of how to "fix the relative position of the slide 9 and the working chamber 7 so that the guide rod 17 is fixed in the middle and lower position of the guide rail 18", but also indirectly realizes the automation of demoulding. A fixed seat 14 is symmetrically provided on the top of the working chamber 7. The inner edge of the fixed seat 14 is circular, and a retaining plate is also extended inward from the inner side of the top of the fixed seat 14. The inner edge of the retaining plate is also circular. Then, by providing an inward concave ring on the rotating member 15, the inward concave ring is clamped between the retaining plates, so that the autonomous rotation of the rotating member 15 can be achieved; the center position of the rotating member 15 is rotatably connected to the screw 8 by providing a threaded hole 16. When the top of the working chamber 7 is also provided with a threaded hole 16, the screw 8 can be realized. It rotates between the rotating member 15 and the working chamber 7; and when the bottom end of the screw 8 is connected to the slide 9, it can be pushed out: the slide 9 cannot rotate, and the screw 8 cannot rotate independently, but only by rotating the rotating member 15, the screw 8 can be driven up and down through the threaded hole 16, and then the slide 9 can be driven up and down; in the initial state, the rotating member 15 does not rotate, and the threaded hole 16 can also fix the screw 8 and the slide 9 in the working chamber 7 through the self-locking function, cooperating with the material-taking action of the hook 12.

[0028] Furthermore, when the rotating member 15 is fixed on the connecting ring 63 in the rotating member 6, the fixed limit of the slide 9 can be achieved better. In this way, the staff needs to operate the operating table 1 and the working arm 2 so that the working chamber 7 and the hook 12 are located directly above the blank, and then push the telescopic rod 5 to move downward, driving the lower parts to move downward. After the hook 12 moves downward until it jams the blank, the telescopic rod 5 stops operating, and then the telescopic cylinder 4 is rotated to drive the upper parts (mainly the rotating member 6) to rotate. The rotating member 6 rotates and drives the rotating member 15 to rotate, and drives the screw 8 and the slide 9 upward through the threaded hole 16. The slide 9 moves upward, driving the hook 12 inside it and the blank to move upward and put it into the working chamber 7. Then the rotation of the telescopic cylinder 4 is stopped, and the telescopic rod 5 is restarted to shorten, and the entire structure is moved upward and no longer contacts the mold, completing the demolding of the blank.

[0029] As a preferred embodiment, in order to further promote the rapid rotation of the rotating member 15 and avoid the device from overloading when it rubs against the top of the working chamber 7, thereby affecting the material removal, a first bearing ring 20 is provided at the top of the working chamber 7, and a second bearing ring 21 is correspondingly provided at the bottom of the rotating member 15. The slots of the second bearing ring 21 and the first bearing ring 20 are arranged relative to each other, so that a plurality of balls 22 can be installed between the second bearing ring 21 and the first bearing ring 20, so that the rotation of the rotating member 15 becomes smoother, and a greater force can be provided for the rise of the screw 8, thereby enhancing the durability of the device.
