Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing, and more specifically, to a flat-blade needle shearing mechanism. Background Technology

[0002] A flat-blade shearing mechanism is a mechanical device used for cutting small metal materials, suitable for various cross-sectional shapes such as round, square, and plate. During production, the cross-section becomes smaller, flatness increases, and the gap between the shearing and the frame plane is minimized. It plays a significant role in the flat-cutting process of electronic component pins to meet the requirements of subsequent processes and product dimensions.

[0003] However, when manually cutting the pins of a product using flat-nose pliers, the required size and position of the cut cannot be accurately determined, resulting in low efficiency, high defect rate, and impact on quality. Therefore, a flat-nose pin-cutting mechanism is proposed to address these issues. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a flat-mouth shearing needle mechanism. Through the action of a cylinder, the floating joint of the I-shaped cylinder drives the two upper blades connected to the upper blade mounting limit block to move longitudinally. This causes the piston cylinder inside the pneumatically controlled cylinder to reciprocate linearly within the cylinder body, driving the upper blade mounting limit block to swing up and down. The upper blades then complete the shearing action. Therefore, when shearing multiple products, the product quality has high repeatability and consistency, significantly reducing the defect rate and manufacturing costs.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A flat-mouth shearing mechanism includes a base plate and a product. A vertical plate is fixedly mounted on the top of the base plate. A lower blade mounting limit plate is fixedly mounted on the top of the vertical plate. A lower blade mounting limit plate is also provided on one side of the vertical plate. An upper blade mounting limit block slides on one side of the vertical plate. Two upper blades are mounted on the upper blade mounting limit block. A cylinder fixing plate is fixedly mounted on the top of the vertical plate. A cylinder is fixedly mounted on the top of the cylinder fixing plate. An I-shaped cylinder floating connector is fixedly mounted on the output end of the cylinder. The I-shaped cylinder floating connector passes through the cylinder fixing plate and is slidably connected to it. The I-shaped cylinder floating connector is inserted into the upper blade mounting limit block and fixedly connected to it.

[0009] Furthermore, a product positioning lower blade is fixedly installed on the top of the lower blade mounting limit plate, and both upper blades are inserted into the interior of the product positioning lower blade and slidably connected to it.

[0010] Furthermore, both upper blades are provided with through slots, and the upper blade mounting limit block is provided with a protrusion that mates with the through slot, and the protrusion is provided with a fixing hole.

[0012] Furthermore, a right upper knife guide block and a left upper knife guide block are respectively provided on one side of the base plate of the mechanism and on the corresponding sides of the upper knife mounting limit block. Each of the right upper knife guide block and the left upper knife guide block has two fixing holes. The upright plate of the mechanism has slots that mate with several fixing holes.

[0014] 3. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] This solution utilizes a pneumatic cylinder to cause the floating joint of the I-shaped cylinder to drive the two upper blades connected to the upper blade mounting limit block to move longitudinally. This, in turn, causes the piston cylinder inside the pneumatically controlled cylinder to reciprocate linearly within the cylinder body, driving the upper blade mounting limit block to swing up and down. The upper blades then complete the shearing action. As a result, when shearing multiple products, the product quality has a high degree of repeatability and consistency, which can significantly reduce the defect rate and manufacturing costs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figure 1-4 A flat-mouth shearing mechanism includes a base plate 1 and a product 8. A mechanism upright plate 2 is fixedly installed on the top of the base plate 1. A lower blade mounting limit plate 3 is provided on one side of the mechanism upright plate 2. An upper blade mounting limit block 6 is slidably installed on one side of the mechanism upright plate 2. Two upper blades 7 are provided on the upper blade mounting limit block 6. A cylinder fixing plate 11 is fixedly installed on the top of the mechanism upright plate 2. A cylinder 13 is fixedly installed on the top of the cylinder fixing plate 11. An I-shaped cylinder floating joint 10 is fixedly installed at the output end of the cylinder 13. The I-shaped cylinder floating joint 10 passes through the cylinder fixing plate 11 and is slidably connected to it. The I-shaped cylinder floating joint 10 is inserted into the interior of the upper blade mounting limit block 6 and is fixedly connected to it.

[0025] The product positioning lower blade 12 is fixedly installed on the top of the lower blade mounting limit plate 3, and the two upper blades 7 are inserted into the product positioning lower blade 12 and slidably connected to it.

[0026] The cylinder 13 is used to drive the two upper blades 7 connected to the upper blade mounting limit block 6 to move longitudinally. This causes the piston cylinder inside the cylinder 13 to reciprocate linearly within the cylinder body, which in turn causes the upper blade mounting limit block 6 to swing up and down. The upper blades 7 then complete the shearing action. As a result, when multiple products 8 are sheared, the product quality has high repeatability and consistency, which can significantly reduce the defect rate and manufacturing costs.

[0027] Both upper blades 7 have through grooves, and the upper blade mounting limit block 6 has a protrusion that mates with the through groove. The protrusion has a fixing hole. Both upper blades 7 are inserted into the upper blade mounting limit block 6 and slidably connected to it. The lower blade mounting limit plate 3 has a fixing hole.

[0028] On one side of the base plate 1 of the mechanism, and on the corresponding sides of the upper knife mounting limit block 6, there are upper right knife guide block 4 and upper left knife guide block 5 respectively. The upper right knife guide block 4 and upper left knife guide block 5 each have two fixing holes. The vertical plate 2 of the mechanism has slots that mate with several fixing holes. The upper knife mounting limit block 6 is slidably connected to the upper right knife guide block 4 and upper left knife guide block 5. The bottom of the base plate 1 of the mechanism has friction texture. The cylinder 13 is equipped with a stroke nut 9.

[0029] By inserting the upper blade 7 into the upper blade mounting limit block 6, the upper blade 7 is initially fixed by the protrusion that mates with the through groove on the upper blade 7. The upper blade 7 is then further fixed by the fixing hole on the upper blade mounting limit block 6 that mates with the existing hexagonal head screw, so that the hexagonal head of the screw contacts the upper blade 7 and restricts its position. This makes it easier to replace the upper blade 7 after long-term use.

[0030] Meanwhile, the fixing holes on the lower blade mounting limit plate 3, the upper right blade guide block 4, and the upper left blade guide block 5 facilitate replacement, reducing the possibility that wear and unevenness of the lower blade 12 after long-term use will affect the cutting quality of the product needle 15. At the same time, the upper right blade guide block 4 and the upper left blade guide block 5 are mounted on the mechanism upright plate 2 in a 7-shape, making the upper blade mounting limit block 6 more stable when moving longitudinally. The friction texture on the bottom of the mechanism base plate 1 increases the friction between the mechanism base plate 1 and the table, improving the stability of the device. The stroke nut 9 is installed on the top of the cylinder 13. When the piston of the cylinder 13 moves upward, it will hit the stroke nut 9, thereby preventing the piston from moving further upward. The displacement of the piston can be precisely controlled to ensure that the action of the cylinder 13 is within the required shearing range.

[0031] Working principle: Insert product 8 into product positioning lower blade 12, start the machine cylinder 13 to start action, drive the upper blade mounting limit block 6 to move downward, the upper blade mounting limit block 6 drives the upper blade 7 to move downward, when the upper blade 7 coincides with the product positioning lower blade 12, cut off the product pin 15.

[0032] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
