Description

Technical Field

[0001] The utility model relates to the technical field of material strip production equipment, in particular to an automatic material strip cutting device. Background Art

[0002] Strip terminals are an electronic connection technology that connects electronic components together through strip materials. They are mainly used to achieve high-speed data transmission and signal transmission between circuit boards, as well as to provide power supply. Strip terminals are widely used in electronic connections, information technology, medical equipment, mechanical equipment, automobiles, industrial control and other fields.

[0003] During the production of strip terminals, multiple strips often need to be welded together to form a continuous strip to ensure stamping continuity. However, due to the limitations of the punch press flow channel structure, welding is limited to tailored welding rather than overlap welding. Tailored welding requires the strips to be flat and aligned before welding to avoid misalignment or jamming during stamping. Therefore, the strips must be precisely trimmed before welding to ensure the flatness and alignment of the welded parts. To this end, we propose an automatic strip cutting device.

DETAILED DESCRIPTION

[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0027] Refer to the attached Figures 1-5 An automatic strip cutting device includes a fixed base 1, a cutting cylinder 2 as a power source is provided on the upper part of the fixed base 1, a cutting jig 3 is connected to the output end of the cutting cylinder 2 at the bottom, and a supporting jig 4 is provided on the fixed base 1 below the corresponding cutting jig 3 for supporting two oppositely arranged strips to ensure that the two strips can be cut at the same time to improve cutting efficiency;

[0028] The cutting jig 3 includes an upper template 31 connected to the bottom output end of the cutting cylinder 2, and a cutter 32 arranged below the upper template 31. The side lines of the cutter 32 are consistent, so that the cutting surfaces of the two oppositely arranged material strips correspond to each other, thereby ensuring that the cutting surfaces of the two material strips can be welded to each other when welding the material strips, so that the corresponding surfaces of the two material strips are welded correspondingly without the need for overlap welding, so as to improve the stability of subsequent use of the material strips. A lower die groove 41 is provided in the supporting jig 4 to cooperate with the cutter 32. When the cutter 32 cuts the material strip, the cut parts fall into the lower die groove 41, so that the cut section of the material strip can be separated from other parts without affecting the subsequent material strip cutting.

[0029] In this embodiment, each side of the cutter 32 is composed of multiple vertical surfaces connected in sequence, so that the two oppositely arranged material strips have multiple corresponding cutting surfaces, which not only facilitates the alignment of the two cut material strips during butt welding, but also increases the welding length to increase the stability of the welding.

[0030] In this embodiment, the bottom of the upper template 31 is connected to a pressure plate 33 through a connecting spring 35. A through groove 34 is provided inside the pressure plate 33 for the cutter 32 to pass through, so that when the cutter 32 moves downward to cut the material strip, the pressure plate 33 applies an extrusion force to the two material strips, ensuring that the pressure plate 33 presses the material strips on both sides during the cutting process, avoiding the material strips from shifting during the cutting process, thereby improving the cutting accuracy.

[0031] In this embodiment, in order to ensure the stability of the pressure plate 33 during the up and down movement, a first guide column 36 is provided on the top of the pressure plate 33, and a first sliding hole 37 is opened in the upper template 31 for the first guide column 36 to pass through. The two are adapted to allow the first guide column 36 to slide stably along the inner cavity of the first sliding hole 37 to prevent the pressure plate 33 from shifting.

[0032] In this embodiment, in order to further improve the stability of the entire device, a second sliding hole 38 is opened in the upper template 31, and a second guide column 11 is provided on the fixed seat 1 to penetrate into the second sliding hole 38. The outer wall of the second guide column 11 is provided with a sleeve rod 12. The top of the sleeve rod 12 is connected to the bottom of the upper template 31, and its bottom is connected to the fixed seat 1 through a support spring 13 sleeved on the outer wall of the second guide column 11. When the upper template 31 moves up and down, the second guide column 11 moves relatively in the second sliding hole 38, so that the upper template 31 is more stable during the up and down movement and is not prone to shaking.

[0033] In this embodiment, in order to facilitate the positioning and fixation of the material strip, the fixing seat 1 is provided with a rotatable positioning splint 14 on both sides of the supporting jig 4. One end of the positioning splint 14 is rotatably connected to the fixing seat 1, and the other end is provided with a handle for pulling the positioning splint 14 to pull the positioning splint 14 to move. The positioning splint 14 corresponds to the position of the fixing seat 1 and its top is flush with the top of the supporting jig 4. Pull the wrench to pull the positioning splints 14 on both sides upward, and then place the material strip to the appropriate position below the positioning splint 14, and then put down the positioning splint 14 to fix the two material strips without manual support, thereby improving the safety during the cutting process.

[0034] In this embodiment, the lower mold groove 41 passes through the supporting jig 4, and two pads 5 are provided at the bottom of the fixed seat 1 to ensure that the fixed seat 1 is spaced apart from the ground. A waste box 6 is provided between the two pads 5. The waste box 6 is provided below the lower mold groove 41 to receive the cut waste. The cut waste falls into the waste box 6 through the lower mold groove 41 for collection, which helps to protect a clean working environment.

[0035] Work away: Pull the positioning clamp 14, then place the two oppositely arranged material strips on the supporting fixture 4, lower the positioning clamp 14 and use the positioning clamp 14 to position and fix the material strips to ensure that the material strips are stable and do not move. The cutting cylinder 2 is started to drive the upper template 31 and the cutter 32 to move downward. During this process, the pressure plate 33 at the bottom of the upper template 31 applies extrusion pressure to the material strip to ensure that the material strip will not deviate during the cutting process, thereby improving the cutting accuracy. The cutter 32 moves downward to cut the two material strips, and the cut parts fall into the waste box 6 through the lower mold groove 41 for collection.
