Description

Technical Field

[0001] This utility model relates to the field of hardware processing technology, specifically to an adjustable stroke hardware processing pressing device. Background Technology

[0002] In the field of hardware processing, stamping is a common processing technology. It involves applying pressure to metal sheets and other hardware parts using a stamping device, causing them to undergo plastic deformation or separation, thereby obtaining parts of the desired shape and size. Traditional stamping devices for hardware processing have some limitations in practical applications, mainly in the following aspects:

[0003] Limited processing diversity

[0004] Traditional pressing devices typically have a fixed pressing stroke. This means that when processing hardware parts with different thicknesses or shapes, it is difficult to adjust the stroke to meet diverse processing needs. For example, when processing thinner metal sheets, an excessive pressing stroke may cause excessive deformation or damage to the sheet; while when processing thicker hardware parts, insufficient stroke will prevent effective pressing operations.

[0005] Poor equipment adaptability

[0006] Because of the fixed stroke, companies may need to equip themselves with multiple stamping machines of different specifications for different types of hardware parts. This not only increases equipment costs but also occupies more production space. Switching between different machines also leads to reduced production efficiency and increases time and labor costs in the production process.

[0007] Therefore, an adjustable stroke hardware processing pressing device is needed to improve the above problems. Utility Model Content

[0008] The purpose of this utility model is to provide an adjustable stroke hardware processing pressing device to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] An adjustable stroke hardware processing pressing device includes a pressing device body, with rotating turntables on both sides of the upper end inside the pressing device body. The rotating turntables are driven by a drive pulley. The inner side of the turntable is provided with a mounting groove, and a lead screw is rotatably installed inside the mounting groove. An internally threaded slider is threadedly connected to the surface of the lead screw. A fixed shaft is fixedly installed on the surface of the internally threaded slider. A sleeve is rotatably fitted on the outer side of the fixed shaft. A rotating arm is fixedly installed at the lower end of the sleeve. A stamping slide rod is hinged to the lower end of the rotating arm. A stamping template is fixedly installed at the lower end of the stamping slide rod. A stamping base is provided at the lower end of the pressing device body corresponding to the stamping template. A limiting mechanism is provided on the surface of the turntable.

[0011] As a preferred embodiment of this utility model, the mounting groove is provided with inner sliding grooves on both sides, and the inner threaded slider is slidably arranged with the inner sliding grooves on both sides.

[0012] As a preferred embodiment of this utility model, a limiting ring is fixedly provided at the upper end of the internal thread slider, and a plurality of limiting holes are provided on the surface of the limiting ring. A knob is fixedly provided at the lower end of the internal thread slider.

[0013] As a preferred embodiment of this utility model, the limiting mechanism includes a cylinder, a limiting rod, a spring, and a baffle.

[0014] As a preferred embodiment of this utility model, the cylinder is fixedly mounted on the surface of the turntable, and a limiting rod is slidably provided inside the cylinder, with the limiting rod corresponding to the limiting hole.

[0015] As a preferred embodiment of this utility model, the limiting rod is fixedly provided with a baffle on the inner surface of the cylinder, and the limiting rod is sleeved with a spring on the inner surface of the cylinder.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. Adaptable to various processing needs

[0018] By adjusting the position of the internal threaded slider on the lead screw, the initial position of the stamping slide can be easily changed, thus achieving flexible adjustment of the stamping stroke. This allows the device to adapt to the processing of hardware parts with different thicknesses and shapes. Whether it is a thin plate or a thick plate, processing requirements can be met through simple stroke adjustment. Because the stroke is adjustable, companies do not need to equip themselves with multiple stamping machines of different specifications for different types of hardware parts. This device can complete multiple processing tasks on the same machine, greatly improving equipment utilization and reducing equipment costs and production space occupation.

[0019] 2. Improved ease of operation and efficiency

[0020] The stroke adjustment process is simple and quick; the stroke can be changed simply by rotating the lead screw to move the internal threaded slider. This adjustment method eliminates the need for complex mechanical disassembly and reassembly, greatly reducing adjustment time and improving production efficiency. The device's design allows operators to easily adjust the stroke and maintain the equipment. Even non-technical personnel can master the operation method in a short time, reducing reliance on professional technicians and lowering labor costs. Attached Figure Description

[0030] Please see Figure 1-4This utility model provides a technical solution:

[0031] An adjustable stroke hardware processing pressing device includes a pressing device body 2, with rotating turntables 21 on both sides of the upper end inside the pressing device body 2. The rotating turntables 21 are connected to a drive pulley 1 for transmission. The inner side of the turntables 21 is provided with a mounting groove 14. A lead screw 8 is rotatably mounted inside the mounting groove 14. An internally threaded slider 9 is threadedly connected to the surface of the lead screw 8. A fixed shaft 12 is fixedly mounted on the surface of the internally threaded slider 9. A sleeve 13 is rotatably mounted on the outer side of the fixed shaft 12. A rotating arm 11 is fixedly mounted at the lower end of the sleeve 13. A stamping slide rod 3 is hinged to the lower end of the rotating arm 11. A stamping template 4 is fixedly mounted at the lower end of the stamping slide rod 3. The lower end of the pressing device body 2 is provided with a stamping base 5 corresponding to the stamping template 4, and the surface of the turntable 21 is provided with a limiting mechanism 6. The drive pulley 1 obtains power through an external power source such as a motor. This power source can be an electric motor, which transmits power to the drive pulley 1 through a transmission device such as a belt. The drive pulley 1 is connected to the rotating turntable 21. When the drive pulley 1 rotates, it will drive the rotating turntable 21 to rotate on both sides of the upper end inside the pressing device body 2. This transmission method can be a variety of forms such as gear transmission and belt transmission, to ensure that the rotating turntable 21 can rotate at a certain speed and direction.

[0032] The inner side of the turntable 21 is provided with a mounting groove 14, and a lead screw 8 is rotatably mounted inside the mounting groove 14. The lead screw 8 is connected to the rotating turntable 21, and when the rotating turntable 21 rotates, the lead screw 8 will also rotate. An internal threaded slider 9 is threadedly connected to the surface of the lead screw 8. Due to the rotation of the lead screw 8, the internal threaded slider 9 will move along the axis of the lead screw 8. This movement is based on the principle of thread transmission. The rotation of the lead screw 8 causes the internal threaded slider 9 to be displaced in the axial direction, thereby realizing the adjustment of the position.

[0033] As an example of this utility model, the mounting groove 14 has inner sliding grooves 7 on both sides, and the inner threaded slider 9 is slidably arranged with the inner sliding grooves 7 on both sides.

[0034] As an example of this utility model, a limiting ring 15 is fixedly provided at the upper end of the internal thread slider 9, and a plurality of limiting holes 16 are provided on the surface of the limiting ring 15. A knob 10 is fixedly provided at the lower end of the internal thread slider 9, and a fixed shaft 12 is fixedly provided on the surface of the internal thread slider 9. A sleeve 13 is rotatably sleeved on the outside of the fixed shaft 12. A rotating arm 11 is fixedly provided at the lower end of the sleeve 13. When the internal thread slider 9 moves on the lead screw 8, it will drive the fixed shaft 12, the sleeve 13 and the rotating arm 11 to move as a whole along the axial direction of the lead screw 8.

[0035] A stamping slide rod 3 is hinged to the lower end of the rotating arm 11. As the rotating arm 11 moves, the position of the stamping slide rod 3 will also change accordingly. By adjusting the position of the internal thread slider 9 on the lead screw 8, the initial position of the stamping slide rod 3 can be changed, thereby adjusting the stamping stroke. For example, if the internal thread slider 9 moves upward, the initial position of the stamping slide rod 3 will also move upward, and the stamping stroke will become shorter; conversely, the stroke will become longer.

[0036] The lower end of the stamping slide bar 3 is fixedly provided with a stamping template 4, and the lower end of the pressing device body 2 is provided with a stamping base 5 corresponding to the stamping template 4. When the stamping slide bar 3 moves downward under the action of power, the stamping template 4 will contact the stamping base 5 and perform stamping processing on the hardware parts placed on the stamping base 5.

[0037] As an example of this utility model, the limiting mechanism 6 includes a cylinder 17, a limiting rod 18, a spring 19, and a baffle 20. A fixed shaft 12 is fixedly provided on the surface of the internal thread slider 9, and a sleeve 13 is rotatably sleeved on the outside of the fixed shaft 12. A rotating arm 11 is fixedly provided at the lower end of the sleeve 13. When the internal thread slider 9 moves on the lead screw 8, it will drive the fixed shaft 12, the sleeve 13, and the rotating arm 11 to move as a whole along the axial direction of the lead screw 8.

[0038] A stamping slide rod 3 is hinged to the lower end of the rotating arm 11. As the rotating arm 11 moves, the position of the stamping slide rod 3 will also change accordingly. By adjusting the position of the internal thread slider 9 on the lead screw 8, the initial position of the stamping slide rod 3 can be changed, thereby adjusting the stamping stroke. For example, if the internal thread slider 9 moves upward, the initial position of the stamping slide rod 3 will also move upward, and the stamping stroke will become shorter; conversely, the stroke will become longer.

[0039] The lower end of the stamping slide bar 3 is fixedly provided with a stamping template 4, and the lower end of the pressing device body 2 is provided with a stamping base 5 corresponding to the stamping template 4. When the stamping slide bar 3 moves downward under the action of power, the stamping template 4 will contact the stamping base 5 and perform stamping processing on the hardware parts placed on the stamping base 5.

[0040] As an example of this utility model, the cylinder 17 is fixedly disposed on the surface of the turntable 21, and a limiting rod 18 is slidably disposed inside the cylinder 17, with the limiting rod 18 corresponding to the limiting hole 16.

[0041] As an example of this utility model, a baffle 20 is fixedly provided on the inner surface of the cylinder 17 for the limiting rod 18, and a spring 19 is sleeved on the inner surface of the cylinder 17 for the limiting rod 18.

[0042] Working principle: When using,

[0043] The drive pulley 1 obtains power from an external power source such as an electric motor; this power source can be an electric motor, which transmits power to the drive pulley 1 through a transmission device such as a belt; the drive pulley 1 is connected to the rotating turntable 21 for transmission, and when the drive pulley 1 rotates, it will drive the rotating turntable 21 to rotate on both sides of the upper end inside the pressing device body 2; this transmission method can be a variety of forms such as gear transmission and belt transmission, to ensure that the rotating turntable 21 can rotate at a certain speed and direction;

[0044] The inner side of the turntable 21 is provided with a mounting groove 14, and a lead screw 8 is rotatably mounted inside the mounting groove 14. The lead screw 8 is connected to the rotating turntable 21, and when the rotating turntable 21 rotates, the lead screw 8 will also rotate. An internal threaded slider 9 is threadedly connected to the surface of the lead screw 8. Due to the rotation of the lead screw 8, the internal threaded slider 9 will move along the axis of the lead screw 8. This movement is based on the principle of thread transmission. The rotation of the lead screw 8 causes the internal threaded slider 9 to be displaced in the axial direction, thereby realizing the adjustment of the position.

[0045] A fixed shaft 12 is fixedly provided on the surface of the internal thread slider 9, and a sleeve 13 is rotatably sleeved on the outside of the fixed shaft 12; a rotating arm 11 is fixedly provided at the lower end of the sleeve 13; when the internal thread slider 9 moves on the lead screw 8, it will drive the fixed shaft 12, sleeve 13 and rotating arm 11 to move as a whole along the axis of the lead screw 8.

[0046] A stamping slide rod 3 is hinged to the lower end of the rotating arm 11. As the rotating arm 11 moves, the position of the stamping slide rod 3 will also change accordingly. By adjusting the position of the internal thread slider 9 on the lead screw 8, the initial position of the stamping slide rod 3 can be changed, thereby adjusting the stamping stroke. For example, if the internal thread slider 9 moves upward, the initial position of the stamping slide rod 3 will also move upward, and the stamping stroke will become shorter; conversely, the stroke will become longer.

[0047] The lower end of the stamping slide bar 3 is fixedly provided with a stamping template 4, and the lower end of the pressing device body 2 is provided with a stamping base 5 corresponding to the stamping template 4. When the stamping slide bar 3 moves downward under the action of power, the stamping template 4 will contact the stamping base 5 and perform stamping processing on the hardware parts placed on the stamping base 5.

[0048] During the stamping process, the stroke of the stamping slide bar 3 is determined by the previously adjusted position, thereby enabling precise stamping of hardware parts with different thicknesses or processing requirements;

[0049] When it is necessary to limit the position of the internal thread slider 9, the limiting mechanism 6 can be operated; the limiting rod 18 can slide inside the cylinder 17, and under the elastic force of the spring 19, the limiting rod 18 will be inserted into the limiting hole 16 on the internal thread slider 9.

[0050] In this way, the internal thread slider 9 is fixed in a specific position to prevent it from moving freely on the lead screw 8. When the stroke needs to be adjusted, the elastic force of the spring 19 can be overcome, the limit rod 18 can be pulled out from the limit hole 16, and then the internal thread slider 9 can be moved to a new position and the limit rod 18 can be reinserted to realize the stroke adjustment and limit function.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
