UTILITY MODEL CONTENTS

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a correcting mechanism for copper bar stamping die to solve the above problems.

[0006] The technical scheme of the utility model is as follows: a correcting mechanism for copper bar stamping die, comprising,

[0007] a top die, the lower side of the top die is connected with an upper die;

[0008] a bottom die, the upper side of the bottom die is connected with a lower die;

[0009] a punch module, the punch module is fixed on the top die and penetrates downward through the upper die, and the punch module is used for stamping a through hole on the copper bar;

[0010] A straightening rod is fixed to the top die and extends downward through the upper die. The straightening rod is located behind the punch module and is located directly above and matches the through hole. The lower edge of the straightening rod is chamfered.

[0011] The top mold is located above the bottom mold, and the upper and lower molds are fitted together with a stamping channel between them for the copper strip to pass through.

[0012] By adopting the above technical solution, the copper strip is first punched through a hole by the punch module, and then continues to be pushed in. While the top die is pressing down, it drives the lower end of the straightening rod with a chamfer to be inserted into the through hole. When the pushing distance of the copper strip is insufficient and it does not reach the preset position, but the vertical projection of the lower end of the straightening rod falls into the through hole, as the straightening rod gradually moves down, one side of the chamfer of the straightening rod contacts one side of the through hole, so that the straightening rod can forcibly push the copper strip forward or backward, so that the copper strip reaches the preset position, correcting the small deviation of the copper strip during the conveying process. There is no need to stop the machine or operate manually, which effectively improves the work efficiency.

[0013] This utility model is further configured to include:

[0014] A warning rod is movably connected to the top mold and extends downward through the upper die. The warning rod is located behind the punch module and directly above and matches the through hole. A spring is provided between the warning rod and the top mold. A detection device for detecting the movement of the warning rod is provided inside the top mold.

[0015] The lower end of the warning rod is lower than the lower end of the correction rod, and both the warning rod and the correction rod are set vertically.

[0016] By adopting the above technical solution, when the offset distance of the fed copper strip is large and the vertical projection of the lower end face of the straightening rod coincides with the copper strip, the top mold will move the warning rod downward while pressing down, so that the lower end of the warning rod abuts against the upper surface of the copper strip, thereby causing the warning rod to retract into the top mold and trigger the detection device, stop the equipment, and notify the staff to operate, so as to avoid the straightening rod from contacting the upper surface of the copper strip and causing damage to the straightening rod and the copper strip.

[0017] The present invention is further configured such that: the length of the correction rod is the same as the length of the through hole, the length of the lower end face of the correction rod is less than the length of the through hole, and the length of the warning rod is less than the length of the through hole.

[0018] By adopting the above technical solution, the lower end of the straightening rod can be easily inserted into the through hole. As the straightening rod gradually moves down, one side of the chamfer of the straightening rod contacts one side of the through hole, thereby enabling the straightening rod to forcefully push the copper strip forward or backward for straightening.

[0019] The present invention is further configured such that: the lower die has an insertion hole at the bottom of the stamping channel for inserting the correction rod and the warning rod.

[0020] By adopting the above technical solution, the correction rod and the warning rod can be inserted into the socket after passing through the through hole.

[0021] The present invention is further configured such that: multiple straightening rods are equidistantly arranged along the conveying direction of the copper strip, and the spacing between adjacent straightening rods is the same as the spacing between adjacent through holes.

[0022] By adopting the above technical solution, the multiple setting of straightening rods can effectively improve the strength of the copper strip during straightening and avoid breakage. Attached Figure Description

The lower edge of the straightening rod 5 is chamfered.

[0038] The top mold 1 is located above the bottom mold 2, and the upper mold 10 and the lower mold 20 are fitted together with a stamping channel 6 between them for the copper strip 4 to pass through.

[0039] By adopting the above technical solution, the copper strip 4 is first punched through the through hole 40 by the punch module 3, and then continues to be pushed in. While the top die 1 is pressing down, it drives the lower end of the straightening rod 5, which has a chamfer, to be inserted into the through hole 40. When the pushing distance of the copper strip 4 is insufficient and it does not reach the preset position, but the vertical projection of the lower end face of the straightening rod 5 falls into the through hole 40, as the straightening rod 5 gradually moves down, one side of the chamfer of the straightening rod 5 contacts one side of the through hole 40, so that the straightening rod 5 can forcibly push the copper strip 4 forward or backward, so that the copper strip 4 reaches the preset position, correcting the small deviation of the copper strip 4 during the conveying process. There is no need to stop the machine or perform manual operation, which effectively improves the work efficiency.

[0044] In this embodiment of the utility model, the length L1-1 of the correction rod 5 is the same as the length L2 of the through hole 40, the length L1-2 of the lower end face of the correction rod 5 is less than the length L2 of the through hole 40, and the length L3 of the warning rod 7 is less than the length L2 of the through hole 40.

[0045] By adopting the above technical solution, the lower end of the straightening rod 5 can be easily inserted into the through hole 40. As the straightening rod 5 gradually moves down, one side of the chamfer of the straightening rod 5 contacts one side of the through hole 40, thereby enabling the straightening rod 5 to forcefully push the copper strip 4 forward or backward for straightening.
