[0002] Progressive die is also called continuous die, which consists of multiple stations, each station is linked in sequence to complete different processing, and a series of different stamping processes are completed in one stroke of the punch press. After one stroke is completed, the punch press feeder moves the material forward according to a fixed step distance, so that multiple processes can be completed on one die;

[0003] In order to improve the processing efficiency of the progressive die, a feeding device is usually set on the progressive die. The length of some sheets is greater than the sheet length required by the progressive die. The existing progressive die feeding device lacks the function of cutting the sheets. If the sheets are cut before entering the progressive die, it will cause extra time and affect the processing efficiency. Utility Model Content

[0004] In view of this, the utility model provides a feeding device for a continuous progressive die, which is used to solve the technical problem that the length of some sheets is greater than the sheet length required by the progressive die, and the existing progressive die feeding device lacks the cutting function of the sheet, affecting the processing efficiency.

[0005] The utility model is achieved in this way:

[0035] The left ends of the progressive die upper die 1 and the progressive die lower die 2 are provided with a sheet material cutting mechanism, which comprises a cutter 11 slidably connected on the left side of the progressive die upper die 1, and a cutter groove 30 longitudinally opened on the right side of the feeding table 3, and the cutter 11 and the cutter groove 30 are opposite in position and matched in size;

[0036] A support plate 51 is fixedly installed on the top of the progressive die upper die 1, a threaded hole is opened in the middle of the support plate 51, a screw 53 is threadedly connected to the threaded hole, a connecting sleeve 12 is fixedly installed on the top of the cutter 11, and the bottom end of the screw 53 is rotatably connected to the connecting sleeve 12.

[0037] Optionally, in the above technical solution, an upper limit ring 54 is fixedly installed at the bottom of the screw rod 53, and an upper ring groove 13 extending downward is formed on the top wall of the connecting sleeve 12, and the upper limit ring 54 is rotatably connected in the upper ring groove 13;

[0038] A lower limiting ring 55 is fixedly mounted on the bottom of the upper limiting ring 54 . A lower limiting ring 14 extending downward is formed on the upper annular groove 13 . The lower limiting ring 55 is rotatably connected in the lower annular groove 14 .

[0039] Optionally, in the above technical solution, two support rods 52 are symmetrically slidably connected to the top wall of the support plate 51 , and the bottom ends of the support rods 52 are fixedly mounted on the top of the cutter 11 .

[0040] Optionally, in the above technical solution, two material storage plates 32 are fixedly installed at the left end of the feeding table 3, and the bottom of the two material storage plates 32 is provided with a feeding port 33 for the plate material to pass through, and the front and rear walls of the two material storage plates 32 are fixedly installed with limit plates 34, and the limit plates 34 on both sides are arranged close to each other.

[0041] Optionally, in the above technical solution, a column 41 is fixedly installed on the left side of the feeding platform 3, a fixed end of a telescopic cylinder 42 is fixedly installed on the top of the column 41, and a movable end of the telescopic cylinder 42 extends to the right and a stop plate 43 is fixedly installed at the end.

[0042] Optionally, in the above technical solution, the bottom wall of the abutment plate 43 is slidably connected to the top wall of the feeding platform 3 , and the abutment plate 43 passes through the feeding port 33 .

[0043] The height of the feeding port 33 is greater than the thickness of the sheet material, and the thickness of the sheet material is greater than the thickness of the abutment plate 43. This arrangement can push one sheet material at a time.

[0044] The length of the feeding port 33 is adapted to the width of the sheet material, and the length between the two storage plates 32 is adapted to the length of the sheet material. This arrangement avoids deviation of the sheet material when it is stored.

[0045] The length of the feeding port 33 is matched with the width of the abutment plate 43 and the sheet material, so that the sheet material can pass through the feeding port 33 smoothly.

[0046] The left side of the material storage plate 32 has two rows of rollers 35 rotatably connected to the feeding platform 3. The rollers 35 abut against the baffle plate 31 and the abutment plate 43 at the same time. The rollers 35 are arranged to prevent the abutment plate 43 from deflecting when moving, and to make the abutment plate 43 move more smoothly.

[0047] A knob 50 is fixedly mounted on the top of the screw rod 53 to facilitate the rotation of the screw rod 53;

[0048] The baffle plate 31 and the limit plate 34 are provided to prevent the sheet material from sliding off.

[0049] Working principle:

[0050] When in use, the telescopic cylinder 42 is started to make its movable end push the plate 43 to move rightward, and the plate 43 passes through the feeding port 33 to push the sheet material at the lowest end to the right, and quickly pushes it to the position where the sheet material is placed in the lower die 2 of the progressive die;

[0051] When the sheet metal does not need to be cut, the knob 50 is turned clockwise to make the screw rod 53 rotate and move upward in the threaded hole, and the upper limit ring 54 and the lower limit ring 55 rotate in the upper ring groove 13 and the lower ring groove 14 respectively, and drive the connecting sleeve 12 to move upward. Even if the lowest end of the cutter 11 is higher than the bottom wall of the progressive die upper die 1, the progressive die upper die 1 is moved downward to be molded with the progressive die lower die 2, and the sheet metal is processed. The position of the cutter 11 is such that it does not extend into the cutter groove 30, and the sheet metal will not be cut.

[0052] When the sheet needs to be cut, the knob 50 is turned counterclockwise to make the screw 53 rotate and move downward in the threaded hole, and the upper limit ring 54 and the lower limit ring 55 rotate in the upper ring groove 13 and the lower ring groove 14 respectively, and drive the connecting sleeve 12 to move downward, even if the lowest end of the cutter 11 is slightly lower than the bottom wall, at this time, the upper die 1 of the progressive die is moved downward to be molded with the lower die 2 of the progressive die, and the sheet is processed. The cutter 11 follows the downward movement and can extend into the cutter groove 30 to complete the cutting of the sheet.

[0053] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
