Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rectifying devices, and particularly relates to a rectifying device for feeding a punching machine. Background Art
[0002] When manufacturing strip steel members such as drawer slides, it is necessary to first use a punching machine to punch and form the strip steel. When the punching machine is punching, it is necessary to feed the material periodically from one side, generally by using a steel bar coil for feeding. When feeding the steel bar, it is necessary to maintain the accuracy of its angle to ensure the punching effect. To solve the above problems, technicians installed a pressure roller at the feeding port of the punching machine to press the steel bar. In subsequent improvement schemes, a correction and compaction device was used to enhance the compaction effect. However, since the steel bar will twist or deform after being unrolled, both of these two schemes are difficult to prevent the steel bar from generating lateral displacement and cannot reduce the waste rate during the punching process. Summary of the Utility Model

A toothed structure is provided on the side surface of the toothed plate. A triangular structure is provided on the side surface of the upper roller group. The toothed structure can abut against the triangular structure.
[0005] Further, both the toothed structure and the triangular structure are right-angled triangles. The hypotenuse of the toothed structure is located above, and the hypotenuse of the triangular structure is located below.

[0019] In order to further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined invention purpose, the following, in combination with the drawings and preferred embodiments, will detail the specific implementation manners, structures, features and their effects of the present utility model as follows.
[0020] As Figures 1-5As shown in the figure, a deviation rectifying device for feeding a stamping machine includes a fixed frame 1, a toothed plate 2, an upper roller group 3 and a lower roller group 4. The upper roller group 3 and the lower roller group 4 are correspondingly arranged one above the other in the fixed frame 1. The first roller 301 with a sunken middle part and the second roller 401 with a sunken middle part are respectively arranged in the upper roller group 3 and the lower roller group 4 to laterally restrict and rectify the steel bar located between the upper roller group 3 and the lower roller group 4, so that the steel bar always enters the stamping machine in the center. A sliding groove 102 is arranged inside the fixed frame 1. The upper roller group 3 and the lower roller group 4 are respectively slidably connected to the sliding groove 102. The upper end of the toothed plate 2 is hinged in the sliding groove 102. A toothed structure 201 is arranged on the side surface of the toothed plate 2. A triangular structure 302 is arranged on the side surface of the upper roller group 3. The toothed structure 201 and the triangular structure 302 have corresponding shapes. Under the action of gravity, the toothed plate 2 naturally hangs down, and the toothed structure 201 can abut against the triangular structure 302. After abutting, the vertical movement of the upper roller group 3 can be restricted, and the vertical position of the steel bar located between the upper roller group 3 and the lower roller group 4 can be limited, ensuring that the first roller 301 and the second roller 401 always press the steel bar tightly, and further strengthening the deviation rectifying effect of the first roller 301 and the second roller 401 on the steel. Under the lateral and vertical restriction and deviation rectification of the upper roller group 3 and the second roller 401 group, the steel bar always enters the stamping machine in the center, thus ensuring the accuracy of stamping and the stamping effect. Both the first roller 301 and the second roller 401 are made of high manganese steel and are carburized, with good wear resistance.
[0021] In the above embodiment, both the toothed structure 201 and the triangular structure 302 are right triangles. The hypotenuse of the toothed structure 201 is located above, and the hypotenuse of the triangular structure 302 is located below. During the downward sliding process of the upper roller group 3, the inclined surface of the toothed structure 201 slides on the inclined surface of the triangular structure 302, and the triangular structure 302 continuously crosses over the toothed structure 201. The triangular structure 302 can be embedded between consecutive toothed structures 201. When the first roller 301 presses downward against the steel bar, the right-angle side of the triangular structure 302 abuts against the right-angle side of the toothed structure 201 up and down, preventing the upper roller group 3 from sliding upward and ensuring that the first roller 301 always presses the steel bar to ensure the deviation rectifying effect. The upper end of the toothed plate 2 protrudes from the upper end surface of the fixed frame 1. When resetting the upper roller group 3, the upper end of the toothed plate 2 can be pressed to separate the toothed structure 201 from the triangular structure 302. The toothed plate 2 releases the upper roller group 3, and the upper roller group 3 can slide upward and pass a new steel bar through the space between the upper roller group 3 and the second roller 401 group. A notch 101 is arranged at the upper corner of the fixed frame 1, and the upper end of the toothed plate 2 is located in the notch 101, which is convenient for pressing the toothed plate 2.
[0022] In the above embodiment, a first pin hole 103 communicating with the sliding groove 102 is provided on the side of the fixed frame 1. A pin can be arranged in the first pin hole 103, and the pin can abut against the toothed structure 201. After pressing the toothed plate 2, the first pin can prevent the toothed plate 2 from sagging, facilitating the operation of the staff, and then being pulled out after the new steel bar is loaded. A second pin hole 104 is provided on the side of the fixed frame 1, and a positioning hole is provided on the side of the lower roller group 4. A pin can be arranged in the second pin hole 104, and the pin can be inserted into the positioning hole to adjust and fix the height of the lower roller group 4. A support 5 is provided on the side of the fixed frame 1, and a spring 6 is arranged in the support 5. The toothed plate 2 is connected to the support 5 through the spring 6, adding an auxiliary force on the basis of the natural sagging of the toothed plate 2, making the combination of the triangular structure 302 and the toothed structure 201 closer, and also adding a certain damping to the downward sliding of the upper roller group 3, preventing the upper roller group 3 from directly falling onto the steel bar. Instead, by gently pushing down, the upper roller group 3 can be slowly advanced to the upper end of the steel bar and complete the abutment.
[0023] Description of the working mode of the present utility model:
[0024] In the initial state without loading the steel bar, adjust the height of the second roller group 401 so that its upper end is flush with the stamping position. Press the upper end of the toothed plate 2 with a finger to lift the lower end to the side around the hinge point, and then fix the toothed plate 2 with the first pin. Then lift the upper roller group 3 to the top, pull out the first pin and release the toothed plate 2, so that the triangular structure 302 and the continuous toothed structure 201 are mutually embedded and maintain a close abutting relationship under the action of the spring 6. At this time, the upper roller group 3 is kept at the top inside the fixed frame 1. After the steel bar coil is loaded on the feeding rack, pull the steel bar from the feeding place to this device and pass it between the first roller 301 and the second roller 401. Clamp it with the fixture of the stamping machine and cooperate with the feeding rack to straighten the steel bar. At this time, the upper roller group 3 of this device can be pushed downward, so that the first roller 301 abuts against the upper end of the steel bar downward under the mutual sliding of the triangular structure 302 and the toothed structure 201 to pre-clamp the steel bar; since the uncoiled steel bar will be twisted or deformed, there is a gap between the steel bar and the first roller 301 and the second roller 401. In the initial stage of continuous stamping when the stamping machine is started, it is necessary to compress this gap by pressing down the upper roller group 3, so that the first roller 301 and the second roller 401 tightly clamp the steel bar, and vertically press and horizontally correct the steel bar through the middle parts where the first roller 301 and the second roller 401 sink, ensuring that the steel bar is always accurately sent to the stamping place, thereby ensuring the accuracy of stamping and the stamping effect.
[0025] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention.
