Description

Technical Field

[0001] This utility model relates to the field of aluminum capacitor production technology, and in particular to a continuous pressing device for aluminum capacitor production. Background Technology

[0002] Capacitors are one of the most commonly used resistive components, with high demand and the need for mass production. Currently, aluminum capacitor shells are formed by pressing upper and lower dies together using a stamping machine. To meet the needs of mass production, equipment capable of continuous pressing is required to continuously produce shells. During continuous production, the dies will generate heat through friction, and the high temperature of the dies will eventually affect the forming effect. The commonly used cooling method is oil spraying, but the cooling effect of oil spraying is limited.

[0003] Publication number CN209886507U discloses a continuous pressing device for producing self-cooled solid aluminum capacitors. The device includes a support frame, a stamping cylinder fixedly connected to the top of the support frame, a push rod fixedly connected to the lower end of the stamping cylinder, and the lower end of the push rod penetrating the top of the support frame and fixedly connected to an upper mold. A telescopic water inlet pipe is fixedly connected to the left side of the upper mold, and a straight water pipe is installed inside the upper mold. This continuous pressing device for producing self-cooled solid aluminum capacitors can continuously transport lower molds. After the lower mold is placed on the push roller, it is transported to the conveyor roller. Subsequent lower molds push the previous lower molds below the upper mold for pressing. Telescopic water inlet pipes and telescopic water outlet pipes are connected to the left and right sides of the upper mold, respectively. Water is injected into the straight water pipe of the upper mold through the water inlet pipe, then flows into a water collection pan. After cooling the bottom of the upper mold, the water flows into a spiral coil to cool the sides of the upper mold.

[0004] Although the above-mentioned solution can cool the upper mold and perform continuous pressing operation, the lower mold is unstable when placed on the push roller and is difficult to align with the upper mold. The pressing operation of the equipment is troublesome and has poor stability. Furthermore, the spiral coil and cooling water flow make it difficult to make large-area contact with the upper mold for batch pressing. The cooling effect of the equipment on the upper mold is generally poor. Therefore, we propose a continuous pressing device for aluminum capacitor production. Utility Model Content

[0005] The main purpose of this utility model is to provide a continuous pressing device for aluminum capacitor production. By setting a support and positioning unit, it solves the problems of troublesome alignment and poor stability in the pressing operation of the equipment.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a continuous pressing device for aluminum capacitor production, comprising two symmetrically arranged support plates, and further comprising: a support positioning unit and a pressing cooling unit disposed at the top of the two support plates, and a transmission assembly disposed between the two support plates;

[0007] The support and positioning unit includes a rectangular frame plate, a bidirectional screw rod, a support block, a support base plate, a support column, and a positioning plate. A positioning groove is provided at the center of the top surface of the support plate. The rectangular frame plate is hollow inside and fixedly mounted on the positioning groove. The bidirectional screw rod is movably mounted on the inner wall of one end of the rectangular frame plate. There are four support blocks in total, divided into two groups. One group of support blocks respectively corresponds to the two symmetrically arranged positive and negative threads on the bidirectional screw rod. A support base plate is fixedly mounted on the top of every two support blocks located on the same vertical center horizontal plane. The support column is fixedly mounted on the top surface of the support base plate at the end away from the vertical central axis of the rectangular frame plate. The positioning plate is T-shaped and fixedly mounted on the top of the support column. A turntable is fixedly mounted on the end of the bidirectional screw rod that extends movably to the outside of the rectangular frame plate.

[0008] The pressing and cooling unit includes an upper support frame, a stamping cylinder, a cold water storage box, a first partition, a second partition, a water inlet pipe, a water outlet pipe, and a pressing upper mold. The upper support frame is fixedly installed on the top surface of two support horizontal plates. The stamping cylinder is fixedly embedded in the center of the top surface of the upper support frame. The cold water storage box is fixedly installed at the output end of the stamping cylinder. Several first and second partitions are provided. Several first and second partitions are equidistantly and alternately fixed on the inner wall of the cold water storage box. A first flow port is opened on one side of the first partition, and a second flow port is opened on one side of the second partition. The positions of the first and second flow ports are staggered. The water inlet pipe and the water outlet pipe are respectively fixedly installed on the side walls of both ends of the cold water storage box. The pressing upper mold is fixedly installed on the bottom surface of the cold water storage box.

[0009] Preferably, the support positioning unit further includes a guide rod, which is fixedly mounted on the inner wall of the other end of the rectangular frame plate and movably passes through another set of support blocks. The support column and the positioning plate are arranged in a one-to-one correspondence with the support base plate.

[0010] Preferably, both the inlet pipe end face and the outlet pipe end face are fixedly provided with connecting flanges, which mainly cooperate with the inlet pipe and the outlet pipe to connect to external pipes to pump external cooling water.

[0011] Preferably, the transmission assembly includes a transmission roller, a conveyor belt, and a transmission motor. There are two transmission rollers, which are symmetrically and movably arranged between two support plates.

[0012] Preferably, the rectangular frame plate, the support block, and the supporting base plate are all located inside the conveyor belt, and the positioning plate is located above the top surface of the conveyor belt.

[0013] Preferably, a lower support frame is fixedly provided on the bottom surface of the two supporting cross plates.

[0014] Compared with the prior art, the continuous pressing device for aluminum capacitor production of this utility model has the following advantages:

[0015] 1. In this utility model, by setting up a support positioning unit, the bidirectional screw can be controlled to rotate forward and backward on the rectangular frame plate by holding the turntable. Two of the support blocks, which are threaded to the bidirectional screw, move relative to each other under the force to help adjust the distance between the two support base plates above the top surface of the rectangular frame plate. The other two support blocks can slide and move on the guide rod to cooperate with the adjustment of the support base plates and provide auxiliary support. After the two support base plates come together, they can provide stable bottom support for the lower mold above the conveyor belt directly below the top plane of the conveyor belt. The positioning plate, which is fixed on the top surface of one end of the support base plate by the support column and is in the shape of a "T", can move horizontally and use its concave surface to abut against the lower mold. The lower mold can be locked at the center above the top plane of the conveyor belt by the two positioning plates to complete the rapid alignment with the pressing upper mold. The pressing operation of the equipment is simple and highly stable.

[0016] 2. In this utility model, by setting up a pressing and cooling unit, the pressing mold and the cold water storage box can be synchronously adjusted by the stamping cylinder on the upper support frame. The water inlet pipe is connected to the external pipe to introduce cooling water into the interior. Several first partitions and several second partitions that are equidistantly and alternately fixed on the inner wall of the cold water storage box can form multiple water storage areas in the cold water storage box. The first flow port and the second flow port that are set one-to-one on each of the first partitions and each of the second partitions and are staggered in position can ensure that the cooling water flows fully and sequentially through each water storage area. The heat on the pressing mold can be absorbed by the full cold water storage box over a large area. Finally, the water outlet pipe discharges the heat-absorbing cooling water for water replacement. The equipment significantly improves the cooling effect of the pressing mold. Attached Figure Description
