Description

Technical Field

[0001] The invention relates to a stamping die and a stamping device, in particular to a stamping die and a stamping device for punching a battery diaphragm sleeve with flow holes. Background Art

[0002] Since the bag-type battery diaphragm sleeve has only one opening, when the battery is charged to the end, the gas generated by the electrode will precipitate from the open end, which cannot drive the battery electrolyte to flow and migrate inside and outside, resulting in poor electrolyte circulation, which causes uneven electrolyte concentration inside the battery, easily causing early failure of the power battery and shortening the battery life. The sleeve-type battery diaphragm sleeve has openings at both ends. During the recycling process, the electrolyte will drive the sleeve-type battery diaphragm sleeve to move, causing the sleeve-type battery diaphragm sleeve to shift in position, thereby affecting its stability when supporting the positive and negative plates, affecting the performance of the power battery.

[0003] The battery diaphragm sleeve with flow holes is a diaphragm sleeve with flow holes at the bottom of the existing bag-type battery diaphragm sleeve. The flow holes and the open end of the upper part of the diaphragm sleeve form an electrolyte circulation flow channel, which improves the fluidity of the electrolyte in the diaphragm sleeve, ensures the smoothness of the electrolyte circulation in the entire battery and the uniformity of the electrolyte concentration. At the same time, the bottom of the diaphragm sleeve limits the diaphragm sleeve from infinitely moving upward due to the circulation of the electrolyte, ensuring that the diaphragm sleeve can well support the positive and negative plates, and improve the performance stability of the battery. Since the battery diaphragm sleeve has flow holes, the bag-type battery diaphragm sleeve needs to be further processed. Therefore, it is urgent to develop a processing equipment that can process the battery diaphragm sleeve with flow holes. Summary of the invention

[0004] Purpose of the invention: In view of the above-mentioned problems, the purpose of the present invention is to provide a battery diaphragm sleeve stamping die with flow holes, and a stamping device composed of the stamping die, which is used to further process the bag-type battery diaphragm sleeve to obtain a battery diaphragm sleeve with flow holes.

[0005] Technical solution: A stamping die for a battery diaphragm sleeve with a flow hole, comprising a punch mounted on a punch base, a die mounted on a die base, and a guide rod, wherein the punch is relatively arranged above the die, the lower end of the guide rod is connected to the die base, the upper end of the guide rod is connected to the punch base via a bearing, a tooth-shaped groove is provided on the die, a punch is provided with a punch head corresponding to the tooth-shaped groove, and the punch base moves down along the guide rod to the punch head and is inserted into the tooth-shaped groove.

[0006] The bottom end of the bag-type battery diaphragm sleeve opposite to the open end is placed on the die so that it is located between the toothed groove and the punch head. The base of the punch moves down along the guide rod to the punch head and is inserted into the toothed groove, thereby punching a flow hole on the bottom end of the bag-type battery diaphragm sleeve opposite to the open end.

[0007] Furthermore, at least two cylinders are fixed on a surface of the die facing the punching head, and the cylinders are arranged at intervals on the root surfaces of the tooth-shaped grooves and aligned with each other.

[0008] When the bag-type battery diaphragm sleeve is pushed in along the upper surface of the die so that the bag-type battery diaphragm sleeve is located between the toothed groove and the punching head, the column has a limiting effect on the bag-type battery diaphragm sleeve, preventing the bottom end opposite to the opening end of the bag-type battery diaphragm sleeve from exceeding the required position range, thereby ensuring the punching quality.

[0009] Preferably, the cross sections of the toothed grooves are equal or unequal.

[0010] Preferably, the tooth shape of the toothed groove is one of a rectangle, a triangle, a semicircle, and a trapezoid.

[0011] Optimally, when the punch head is inserted into the tooth-shaped groove, there is a gap A of 0.05 mm to 0.5 mm between the outer peripheral surface of the punch head and the inner peripheral wall of the tooth-shaped groove.

[0013] The bag-type battery diaphragm sleeve is placed on the operating table, and the bottom end of the bag-type battery diaphragm sleeve opposite to the open end is facing the stamping die. The bag-type battery diaphragm sleeve is manually pushed in along the upper surface of the die so that the bottom end is located between the toothed groove and the punching head. The power mechanism is operated to drive the punch base downward, so that the punching head contacts the bag-type battery diaphragm sleeve until it is inserted into the toothed groove, and the stamping action is performed, so that a flow hole is punched out on the bottom end of the bag-type battery diaphragm sleeve opposite to the open end.

[0014] Furthermore, the power mechanism includes a press, a clutch, a motor, and a clutch pedal. The press and the clutch pedal are respectively connected to the clutch. The press and the clutch are respectively electrically connected to the motor. The press includes a vertically arranged sliding body, and the punch base is installed at the bottom end of the sliding body.

[0015] When the equipment is working, the motor is turned on and the clutch is in the normally closed state. At this time, the press is in a stationary state under the action of the clutch. When the clutch pedal is pressed, the clutch is in a disengaged state, the press starts, and the sliding body moves down immediately, driving the punch base to move down along the guide rod until the punch head is inserted into the toothed groove. Then the clutch pedal is released, the clutch returns to the closed state, causing the sliding body to move up and back to the initial state, and the punch head is pulled out of the toothed groove, and a stamping action is completed.

[0016] Furthermore, the device also includes an operating baffle and a baffle support block. The two baffle support blocks are installed on the surface of the operating table and are located outside the length direction of the toothed groove. The operating baffle is mounted on the baffle support block so that a gap B is formed between the bottom surface of the operating baffle and the operating table.

[0017] The operating baffle is a transparent plate. The bag-type battery diaphragm sleeve is pushed into the stamping die from the gap B. The operating baffle plays a shielding role between the worker and the stamping die, thereby ensuring the safety of the worker's operation.

[0018] Furthermore, the device also includes a support table, which is arranged between the die base and the machine base, and its bottom surface and top surface are respectively connected to the machine base and the die base, so that there is a gap C between the die base and the machine base.

[0019] There is a through space at the toothed groove along the depth direction and directly passes through the bottom of the die base. During stamping, the stamping waste can fall into the gap C along the toothed groove, thereby preventing the stamping waste from crowding the toothed groove and ensuring the continuous progress of the stamping work.

[0020] Furthermore, the device also includes an alignment block, which is installed on the operating table. The alignment block is perpendicular to the length direction of the toothed groove and is located outside the length direction of the toothed groove.

[0021] When the worker is operating, the side of the bag-type battery diaphragm sleeve is fitted with the alignment block, and the bag-type battery diaphragm sleeve is pushed into the stamping die along the direction of the alignment block, thereby ensuring the consistency of the position of the flow holes on each processed battery diaphragm sleeve.
