Description

Technical Field

[0001] This utility model relates to the field of stamping head protection, specifically a buffer pressure protection device for a double-head terminal block machine. Background Technology

[0002] Double-head terminal crimping machine is a high-efficiency and precision automated equipment for wire harness processing. Its core feature is that the machine head is equipped with two sets of symmetrical or independently adjustable stamping dies and feeding systems. This allows it to complete the terminal crimping operation at both ends of the wire simultaneously or alternately on one machine, greatly improving production efficiency. It is especially suitable for production scenarios that require large-volume crimping of both ends, such as automotive wire harnesses and home appliance wiring.

[0003] Some double-head terminal crimping machines lack buffer protection devices for their punching heads. Due to their high efficiency and high punching frequency, the huge rigid impact and vibration, the high-speed moving punching head will generate a strong reaction force after instantly crimping the terminal. The lack of a buffer device means that this impact force will be directly transmitted to the punching head, the precision servo motor, the ball screw, and the entire machine frame without reservation. Over time, this will lead to accelerated decay of the transmission system's precision, loosening of the ball screw nut, premature wear of the bearings, and even loosening of the machine base bolts, seriously affecting the long-term stability of the equipment and the final crimping quality.

[0004] Furthermore, from the perspective of equipment intelligence, the lack of a buffer device also means that the equipment lacks overload protection capabilities. Once a misoperation occurs (such as double material or incomplete terminal feeding), the stamping head will directly hit a hard obstacle, which can easily lead to damage to the expensive stamping head.

[0005] Therefore, a buffer pressure protection device for a double-ended terminal block machine is provided to address the above-mentioned problems. Utility Model Content

[0006] This invention addresses the problem that the lack of a buffer protection device on the stamping head leads to a shortened service life and easy damage in case of accidents. It provides a buffer pressure protection device for a double-headed terminal block machine.

[0007] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0008] This utility model provides a buffer pressure protection device for a double-headed terminal machine, including a cutting mechanism. Multiple cylinders are installed inside the cutting mechanism, and piston rods are slidably installed at the bottom of the cylinders. A punching head for cutting is installed below the piston rods. A buffer chamber is fixedly installed on the outside of the piston rods through a fracture column. When the impact force increases, the fracture column breaks first.

[0009] A buffer spring is installed inside the buffer chamber for cushioning. The buffer spring is indirectly connected to the punch head. When the punch head is subjected to impact force, the buffer spring is compressed to absorb part of the energy.

[0010] Preferably, a connecting flange is fixedly installed on the top of the stamping head by bolts, a push plate is fixedly installed on the top of the connecting flange, the push plate is slidably installed inside the buffer chamber, and the bottom of the buffer spring is fixedly installed on the top of the push plate.

[0011] Preferably, an upper push plate is fixedly installed on the top of the buffer spring, the upper push plate is slidably installed inside the buffer chamber, and a threaded post is rotatably installed on the top of the upper push plate, the threaded post penetrating the top of the buffer chamber.

[0012] Preferably, a limiting post is slidably installed through the top of the threaded post.

[0013] Preferably, a limiting block is fixedly installed on the top of the buffer chamber, and multiple limiting grooves are opened on the inner side of the limiting block, which cooperate with the limiting post.

[0014] Preferably, an anti-detachment magnet is fixedly installed inside the limiting groove.

[0015] Preferably, the buffer chamber has a through-hole for ventilation.

[0016] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0017] The positive and progressive effects of this utility model are as follows:

[0018] When the stamping head is working, the buffer spring is compressed, which absorbs part of the reaction force, reduces the wear of the stamping head, and extends its service life.

[0019] If the stamping head collides rigidly with the material or base plate below it, the pressure it experiences increases. That is, the pressure on the fracture column exceeds the maximum bearing capacity, causing the fracture column to break. This allows the stamping head to move upward or deflect to avoid serious damage to the stamping head and reduce economic losses caused by accidents. Attached Figure Description

[0025] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0026] First embodiment:

[0027] like Figure 1-3 As shown, a buffer pressure protection device for a double-headed terminal machine includes a cutting mechanism 1. Multiple cylinders 2 are installed inside the cutting mechanism 1. A piston rod 3 is slidably installed at the bottom of the cylinder 2. A punch head 16 for cutting is installed below the piston rod 3. A buffer chamber 5 is fixedly installed on the outside of the piston rod 3 through a fracture column 4. When the impact force increases, the fracture column 4 breaks first.

[0028] A buffer spring 8 is installed inside the buffer chamber 5 for buffering. The buffer spring 8 is indirectly connected to the punch head 16. When the punch head 16 is subjected to impact force, the buffer spring 8 is compressed to absorb part of the energy.

[0029] Furthermore, a connecting flange 15 is fixedly installed on the top of the stamping head 16 by bolts, which facilitates disassembly, replacement and installation. A push plate 7 is fixedly installed on the top of the connecting flange 15. The push plate 7 is slidably installed inside the buffer chamber 5. The bottom of the buffer spring 8 is fixedly installed on the top of the push plate 7.

[0030] Furthermore, the outer side of the buffer chamber 5 is provided with a ventilation hole 6. When the push plate 7 slides inside the buffer chamber 5, the air inside the buffer chamber 5 is kept in communication with the outside through the ventilation hole 6, making the movement of the push plate 7 smoother.

[0031] In this embodiment, the material to be cut is conveyed to the bottom of the punch head 16, the cylinder 2 is started, driving the piston rod 3 and the punch head 16 to move down, cutting the material. The buffer spring 8 is compressed, absorbing part of the reaction force, reducing the wear of the punch head 16, and extending its service life.

[0032] If the stamping head 16 experiences a rigid impact with the material or base plate below it, the pressure it receives increases, meaning the pressure on the fracture column 4 exceeds its maximum bearing capacity, causing the fracture column 4 to break. This allows the stamping head 16 to move upwards or deflect to avoid serious damage to the stamping head 16 and reduce economic losses caused by the accident.

[0033] Second embodiment:

[0034] The difference from the above embodiments is that, as Figure 3 As shown, an upper push plate 9 is fixedly installed on the top of the buffer spring 8. The upper push plate 9 is slidably installed inside the buffer chamber 5. A threaded column 10 is rotatably installed on the top of the upper push plate 9 to adjust the position of the upper push plate 9 inside the buffer chamber 5, thereby controlling the compression margin of the buffer spring 8. The threaded column 10 penetrates the top of the buffer chamber 5.

[0035] In this embodiment, when dealing with different materials, the operator can rotate the threaded column 10 to move the upper push plate 9 downward, compressing the buffer spring 8. This increases the upward resistance of the buffer spring 8, the lower push plate 7, and the punch head 16, shortening the stroke and making it suitable for materials of different materials and shapes, thus expanding its application range.

[0036] Third embodiment:

[0037] The difference from the above embodiments is that, as Figure 3 As shown, a limiting post 11 is slidably installed through the top of the threaded post 10 to extend the rotation arm of the threaded post 10, making it convenient for workers to rotate the threaded post 10.

[0038] Furthermore, a limiting block 12 is fixedly installed on the top of the buffer chamber 5. Multiple limiting grooves 14 are opened on the inner side of the limiting block 12, and the limiting grooves 14 are inserted and engaged with the limiting post 11.

[0039] In this embodiment, when the threaded column 10 rotates, the operator can pull the limiting column 11 out of the limiting groove 14 to increase the lever arm of rotating the threaded column 10, which is more labor-saving. After adjustment, the limiting column 11 is inserted into the limiting groove 14, and the threaded column 10 is not easily rotated due to vibration or other external forces.

[0040] Furthermore, an anti-detachment magnet 13 is fixedly installed inside the limiting groove 14 to attract and fix the limiting post 11.

[0041] In this embodiment, the anti-detachment magnet 13 makes it difficult for the limiting post 11 to detach from the limiting groove 14 due to vibration or other external forces.

[0042] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
