Description

Technical Field

[0001] This utility model relates to the field of terminal crimping machine technology, specifically to a terminal crimping machine with adjustable pressure. Background Technology

[0002] A terminal crimping machine is a device used to connect bare terminals to cables. It is an essential tool in the power industry for continuous crimping of conductors during basic line construction and line maintenance.

[0003] A search revealed a utility model patent with patent authorization announcement number CN114944582B, which discloses a terminal crimping machine, comprising: a crimping seat having a crimping cavity extending through in a straight direction, and a wire feeding port on the side wall of the crimping seat; a first crimping assembly including a first crimping connector and a first driving mechanism, the first crimping connector extending into the crimping cavity and being movable in the direction close to or away from the wire feeding port; and a second crimping assembly.

[0004] Existing terminal crimping machines are prone to deformation after crimping, which can cause them to get stuck on the machine and make it difficult to remove the material. In addition, the stroke of the cylinder used to provide the punching force is relatively fixed, so the pressure during terminal crimping is also relatively constant. This results in a lack of applicability for crimping different types of terminals. Utility Model Content

[0005] The purpose of this utility model is to provide a terminal crimping machine with adjustable pressure, which solves the problem that existing terminal crimping machines are prone to deformation after crimping, causing them to get stuck on the machine and making it difficult to remove the material. At the same time, it solves the problem that the stroke of the cylinder used to provide the punching pressure is relatively fixed, so the pressure during terminal crimping is also relatively constant, which results in insufficient applicability for crimping different types of terminals.

[0023] Please see Figure 3 A baffle 7 is fixedly connected inside the recessed seat 1, and a guide rod 8 is fixedly connected to the bottom of the base plate 5. The guide rod 8 passes through the baffle 7 and is slidably connected to the baffle 7. A limit block 9 is fixedly connected to the bottom of the guide rod 8 and contacts the baffle 7.

[0024] Please see Figures 3-4A lubrication mechanism 4 is provided on the outer side of the sliding column 2. This mechanism lubricates the sliding column 2, reducing wear during extension and retraction, and is suitable for continuous extension and retraction of the sliding column 2. The lubrication mechanism 4 includes a fixing ring 41 fixedly connected to the column body of the sliding column 2. A top pin 42 is fixedly connected to the upper end of the fixing ring 41. A hollow shell 43 is fixedly connected to the top inner side of the recess 1. The sliding column 2 is slidably connected to the inner side of the hollow shell 43.

[0025] The specific implementation process of this utility model is as follows: In use, after inserting the terminal sleeve into the end of the wire harness, both are placed into the recess 1. Then, the cylinder 12 pushes the pressure strip 14 downward. The pressure strip 14, together with the recess 1, presses the wire harness terminals together. At the same time, the pad 3 is forced downward and moves the sliding column 2 downward. The sliding column 2, through the base plate 5, moves the guide rod 8 downward and compresses the spring 10. When the cylinder 12 moves the pressure strip 14 upward, the pad 3 is reset under the action of the spring 10, and the wire harness terminal is ejected from the recess 1 for easy unloading. When column 2 moves upward and resets, the sliding column 2 drives the top pin 42 to be inserted into the hollow shell 43 from the bottom and presses the inclined block 45, thereby using the inclined block 45 to compress the sponge block 44 and release lubricating oil to lubricate the sliding column 2 and reduce wear between it and the recess 1. In addition, by rotating the adjusting rod 13 through the knob 15, the adjusting rod 13 moves axially through the threaded movement between it and the telescopic shaft of the cylinder 12, thereby adjusting the height of the pressure bar 14. In this way, under the premise that the stroke of the cylinder 12 is fixed, the purpose of adjusting the terminal crimping pressure can be achieved.
