Description

Technical Field

[0001] This utility model relates to the field of manual punching and drilling machines, and more specifically, to a manual punching and drilling machine. Background Technology

[0002] Manual punching and drilling machines, as a type of punching equipment that does not require external power and relies on manual operation, are widely used in small and medium-sized processing scenarios such as hardware parts processing, sheet metal cutting, leather goods making, and fabric cutting. They are especially suitable for scenarios without power supply or with mobile operation requirements. With their portability and low cost advantages, they play an irreplaceable role in the fields of handmade production and small-batch production.

[0003] Existing manual punching and drilling machines typically include a frame, a support structure fixed to the top of the frame, a pressure bar that can rotate around a hinge point, a punch connected below the pressure bar, and a punching seat located at the bottom of the frame and coaxial with the punch. During operation, the operator places the part to be punched (such as a thin metal sheet, plastic sheet, leather, etc.) between the punch and the punching seat, and presses down the pressure bar to drive the punch to move vertically toward the punching seat. The punching operation is achieved by the cooperation of the punch and the punching seat.

[0004] However, existing manual punching and drilling machines have the following significant drawbacks in actual use:

[0005] Existing manual punching and drilling machines only achieve drilling by applying force downwards in one direction with the punch. The pressure application method is singular. Under the one-way force application method, the force on the punching part is concentrated at the punch contact point when the punch moves downwards, which can easily lead to defects such as rough edges and cracks in the punched area of ​​the part. Therefore, it is inconvenient to use. So we propose a manual punching and drilling machine to solve the above-mentioned problems. Utility Model Content

[0006] 1. Technical problems to be solved

[0007] To address the problems existing in the prior art, the purpose of this utility model is to provide a manual punching and drilling machine. It features guide rods one and two that sequentially contact the bottom of a pressure rod. When the pressure rod is pressed, the top of guide rod one first contacts the pressure rod, pressing it down to bring the punch at the bottom of guide rod one closer to the top of the punching seat, initially clamping the part to be punched. Then, the pressure rod continues to press down, bringing guide rods one and two into contact with the bottom of the pressure rod simultaneously. At this time, guide rod one continues to press down while guide rod two also presses down, using the seesaw principle of the lever to lift the punching seat upwards. This achieves a bidirectional synchronous pressure punching effect, preventing the force from being concentrated only at the punch contact point, reducing defects such as rough edges and cracks in the punched area, and improving ease of use.

[0008] 2. Technical Solution

[0009] To solve the above problems, the present invention adopts the following technical solution.

[0010] A manual punching and drilling machine includes a base plate 1, a base plate 2, and a reinforcing column. The bottom four corners of the base plate 2 are fixedly welded to the top of the base plate 1 via connecting rods. The reinforcing column is fixedly welded to the top of the base plate 2. A pressure rod is rotatably connected to one side of the top of the reinforcing column.

[0011] The reinforcing column has an upper connecting end and a lower connecting end on both sides. The upper connecting end and the lower connecting end on both sides of the reinforcing column are slidably connected by guide rod one and guide rod two, respectively. A support spring is sleeved on the outer side of guide rod one and guide rod two between the upper connecting end and the lower connecting end. A limit pin is inserted into guide rod one and guide rod two at the bottom of the upper connecting end. The top and bottom of the support spring contact the bottom of the limit pin and the top of the lower connecting end, respectively. The top of the limit pin contacts the bottom of the upper connecting end. A stroke groove is opened on one side of the outer wall of guide rod one and guide rod two. A positioning screw is threaded to one side of the outer wall of the two lower connecting ends. The end of the positioning screw extends into the interior of the lower connecting end, and the end of the positioning screw is slidably connected to the interior of the stroke groove at the corresponding position.

[0012] Furthermore, the top end of the first guide rod has a hemispherical ball head structure, the bottom end of the first guide rod is fixedly installed with a punch, the top end of the second guide rod is threaded with an adjusting bolt, and the top end of the adjusting bolt has a hemispherical ball head structure, and the bottom end of the second guide rod extends through to the bottom of the second base plate.

[0013] Furthermore, a ring seat is fixedly welded to one side of the seat plate, and a punch seat and a T-shaped top piece are sleeved inside the ring seat, with the top rod of the bottom of the T-shaped top piece extending through to the bottom of the ring seat.

[0014] Furthermore, a set of ear seats is fixedly welded to the top of the seat plate, and a rocker arm is rotatably connected between the set of ear seats. The two ends of the rocker arm are in contact with the end of the top rod at the bottom of the T-shaped top piece and the bottom end of the guide rod, respectively.

[0015] Furthermore, the bottom end of the top rod of the T-shaped top member and the bottom end of the second guide rod are both hemispherical ball-head structures.

[0016] 3. Beneficial Effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] In this design, guide rods one and two can sequentially contact the bottom of the pressure rod. When the pressure rod is pressed, the top of guide rod one first contacts the pressure rod, and the guide rod is pressed down, causing the punch at the bottom of guide rod one to move closer to the top of the punch seat, initially clamping the part to be punched. Then the pressure rod continues to press down, causing guide rods one and two to contact the bottom of the pressure rod simultaneously. At this time, guide rod one continues to press down while guide rod two also presses down, using the seesaw principle of the lever to lift the punch seat upward. This achieves a bidirectional synchronous pressure punching effect, where the punch presses down and the punch seat is lifted upward. This avoids the force being concentrated only at the punch contact point, reducing defects such as rough edges and cracks in the punched area, and improving ease of use. Attached Figure Description

[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example 1:

[0028] Please see Figures 1-5 A manual punching and drilling machine includes a base plate 1, a base plate 2, and a reinforcing column 3. The four bottom corners of the base plate 2 are fixedly welded to the top of the base plate 1 via connecting rods 4. The reinforcing column 3 is fixedly welded to the top of the base plate 2. A pressure rod 5 is rotatably connected to one side of the top of the reinforcing column 3.

[0029] The reinforced column 3 has an upper connecting end 301 and a lower connecting end 302 on both sides. The upper connecting end 301 and the lower connecting end 302 on both sides of the reinforced column 3 are slidably connected by guide rod 1 6 and guide rod 2 7 respectively. A support spring 8 is sleeved on the outside of guide rod 1 6 and guide rod 2 7 between the upper connecting end 301 and the lower connecting end 302. A limit pin 9 is inserted into guide rod 1 6 and guide rod 2 7 at the bottom of the upper connecting end 301. The top and bottom of the support spring 8 are in contact with the bottom of the limit pin 9 and the top of the lower connecting end 302 respectively. The top of the limit pin 9 is in contact with the bottom of the upper connecting end 301. A stroke groove 601 is opened on one side of the outer wall of guide rod 1 6 and guide rod 2 7. A positioning screw 10 is threaded on one side of the outer wall of the two lower connecting ends 302. The end of the positioning screw 10 extends into the interior of the lower connecting end 302, and the end of the positioning screw 10 is slidably connected to the interior of the stroke groove 601 at the corresponding position.

[0030] The top end of the guide rod 1 6 has a hemispherical ball head structure, and the bottom end of the guide rod 1 6 is fixedly installed with a punch 11. The top end of the guide rod 2 7 is threaded with an adjusting bolt 701, and the top end of the adjusting bolt 701 has a hemispherical ball head structure. The bottom end of the guide rod 2 7 extends through to the bottom of the seat plate 2 2.

[0031] A ring seat 12 is fixedly welded to one side of the seat plate 2. A punch seat 13 and a T-shaped top piece 14 are sleeved inside the ring seat 12, and the top rod part at the bottom of the T-shaped top piece 14 extends through to the bottom of the ring seat 12.

[0032] A set of ear seats 15 is fixedly welded to the top of the seat plate 1, and a rocker arm 16 is rotatably connected between the set of ear seats 15. The two ends of the rocker arm 16 are in contact with the bottom end of the top rod part of the T-shaped top piece 14 and the bottom end of the guide rod 7, respectively.

[0033] The bottom end of the top rod of the T-shaped top member 14 and the bottom end of the guide rod 2 7 are both hemispherical ball head structures.

[0034] The operating principle of this type of manual punching and drilling machine is as follows:

[0035] First, place the area to be punched on the part to be punched on top of the punching seat 13, and then press down the pressure rod 5. At this time, the top of the guide rod 1 6 first contacts the bottom of the pressure rod 5 and the guide rod 1 6 is pressed down, so that the punch 11 at the bottom of the guide rod 1 6 moves closer to the top of the punching seat 13, initially clamping the part to be punched. Then the pressure rod 5 continues to press down, so that the tops of the guide rod 1 6 and the guide rod 2 7 simultaneously contact the bottom of the pressure rod 5. At this time, the guide rod 1 6 continues to press down while the guide rod 2 7 also presses down. At this time, the rocker arm 16 pushes the punching seat 13 upward in the opposite direction through the seesaw principle, realizing the bidirectional synchronous pressure punching effect of the punch 11 pressing down and the punching seat 13 pushing up, avoiding the force being concentrated only at the punch contact point.

[0036] After the drilling is completed, simply release the pressure on the pressure rod 5. At this time, the guide rod 6 and the guide rod 7 will automatically spring back to their original positions due to the elastic reset effect of the support spring 8. This will cause the punch 11 to lift up and reset, and one end of the rocker arm 16 to lose the pressure of the guide rod 7. Then, under the influence of gravity, the punch seat 13 and the T-shaped top piece 14 will automatically fall down and reset, thus facilitating drilling at the next position of the part to be drilled.

[0037] Example 2:

[0038] In view of the above embodiment 1, further description is provided, see reference. Figures 3-5 The rocker arm 16 and the T-shaped top piece 14 are designed so that when one end of the rocker arm 16 is squeezed by the bottom of the guide rod 7, the other end of the rocker arm 16 is lifted up, and then the punch seat 13 is lifted up through the connection of the T-shaped top piece 14, thereby achieving the bidirectional pressure punching effect of the punch seat 13 and the punch 11.

[0039] 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.
