[0002] In electrical engineering, terminals mostly refer to wiring terminals, that is, wiring terminals. This type of terminal has a variety of forms such as single-hole, double-hole, socket, hook, etc., and there are also many choices of materials, such as silver-plated copper, zinc-plated copper, copper, aluminum, iron, etc. Its main function is to transmit electrical signals or conduct electricity. The production process of terminals usually includes metal stamping, injection molding and other steps. Terminal stamping refers to the use of stamping equipment and molds to apply pressure to metal sheets to cause plastic deformation, so as to obtain terminal products of the desired shape and size.

[0003] The commonly used terminal stamping equipment is the terminal machine, in which the stamping head is the core stamping component of the terminal machine. Since the stamping stroke of the stamping head of the existing terminal machine is fixed, the terminal machine is only suitable for stamping a single type of terminal. When the specifications of the stamped terminals are different, the terminal machine needs to manually adjust the stamping stroke. This process is not only cumbersome but also leads to low stamping efficiency. The use of the terminal machine is always limited, which has an adverse impact on production. Therefore, further improvements to the terminal machine are needed. Summary of the invention

DETAILED DESCRIPTION

[0025] The following is combined with Figures 1 to 6 The present invention will be described in detail.

[0026] The present invention is an adjustable stroke terminal machine, comprising a machine base 1, on which a stamping device 2 is installed, and the stamping device 2 includes a stamping motor 21, a slider 22 and a stamping head 23 connected in sequence, and the stamping motor 21 drives the stamping head 23 to move up and down along the machine base 1 through the slider 22 to stamp the terminal; the machine base 1 is also equipped with an adjusting device 3 for adjusting the stamping stroke of the stamping head 23; the stamping stroke here refers to: the longest distance between the stamping head 23 and the terminal during a single stamping process, that is, the height from the terminal when the stamping head 23 is in the topmost stamping position; in the present technical solution, the adjusting device 3 includes an adjusting motor 31 and a driving shaft 32 that is transmission-connected to the adjusting motor 31, the driving shaft 32 is telescopically connected to the stamping head 23 and the driving shaft 32 can drive the stamping head 23 to rotate, and the stamping head 23 is threadedly connected to the slider 22. The operating principle of the adjustment device 3 is as follows: when the adjustment motor 31 is started, the driving shaft 32 rotates to drive the punch head 23 to rotate. Since the punch head 23 and the slider 22 are threadedly connected, the punch head 23 will produce a lifting displacement inside the slider 22 while rotating, thereby achieving the purpose of adjusting the punching stroke of the punch head 23, and the adjustment process will not interfere with the stamping process of the terminal machine, and can achieve the technical effect of independent stamping and adjustment.

[0027] The terminal machine of the present invention can, through a clever structural design, automatically adjust the stamping stroke of the punch head 23 without affecting the stamping process, so that the terminal machine is no longer limited to stamping terminals of a single specification, and can adjust the stamping stroke at any time according to the specifications of the stamped terminals, significantly expanding the application scope of the terminal machine, being more conducive to production, and simplifying the stamping process of the terminals.

[0028] The punching motor 21 and the regulating motor 31 in the technical solution are arranged perpendicular to each other, and also include an eccentric roller 4, through which the punching motor 21 is connected to the slider 22. Figure 2As shown, when the power of the motor is transmitted to the slider 22 through the eccentric roller 4, the slider 22 can be driven to have a higher punching force during the lifting process, thereby ensuring that the terminal machine can form stably each time it punches and improving the punching yield rate.

[0029] As an embodiment, the eccentric roller 4 includes a roller body 41 and an eccentric wheel 42 disposed at the front end of the roller body 41 . The roller body 41 is connected to the stamping motor 21 , and the eccentric wheel 42 is connected to the slider 22 .

[0030] Preferably, a transverse slide groove 221 is provided on one side of the slider 22, and the transverse slide groove 221 accommodates the eccentric wheel 42, and the transverse slide groove 221 is slidably connected to the eccentric wheel 42. When the stamping motor 21 drives the eccentric wheel 42 to rotate circumferentially, the transverse slide groove 221 can provide sufficient activity space for the eccentric wheel 42, so that the adjustment motor 31 can stably drive the slider 22 to move up and down along the base 1 to complete the stamping process.

[0031] As another embodiment, the outer end of the eccentric wheel 42 is movably sleeved with a movable block 421, and the movable block 421 is slidably connected to the transverse slide groove 221. Adding the movable block 421 can make the connection between the eccentric wheel 42 and the slider 22 more stable and the movement process more stable.

[0032] Preferably, the base 1 is further provided with a longitudinal slide groove 11, and the slider 22 is slidably connected to the longitudinal slide groove 11. The longitudinal slide groove 11 limits the slider 22 to prevent the slider 22 from deflecting when moving up and down, thereby preventing stamping errors.

[0033] In the present technical solution, a connecting column 231 is fixedly provided on the top of the punch head 23; the driving shaft 32 is hollow, and the driving shaft 32 is sleeved on the outside of the connecting column 231. In order to stably install the punch head 23 in the slider 22, the outer wall of the punch head 23 is provided with an external thread connected to the slider 22, and the slider 22 is also provided with an internal thread matching therewith.

[0034] In order to ensure that the driving shaft 32 does not affect the punching action and can drive the punch head 23 to rotate, the inner wall of the driving shaft 32 is provided with a limiting portion 321, and the outer wall of the connecting column 231 is provided with a flat portion 232 that matches the limiting portion 321. When the driving shaft 32 is sleeved on the outside of the connecting column 231, the limiting portion 321 just abuts against the flat portion 232, and the driving shaft 32 clamps the connecting column 231 from the side, so that the connecting column 231 cannot rotate inside the driving shaft 32 but can perform telescopic movement, which is the key reason why the punching process and the adjustment process can be carried out simultaneously.

[0035] Preferably, the drive shaft 32 extends into the interior of the slider 22, and the drive shaft 32 is movably connected to the slider 22 so that even if the drive shaft 32 drives the punch head 23 to rotate, it does not affect the movement of the slider 22. At the same time, this structural setting can further compact the terminal machine structure and shorten the overall volume of the terminal machine.

[0036] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
