Description

Technical Field

[0001] This utility model relates to the field of punch presses, and in particular to a high-precision, high-strength steel frame punch press with a double-link toggle joint. Background Technology

[0002] A punch press, also known as a stamping machine, is a type of mechanical equipment used for metal processing. It uses an electric motor to drive a flywheel, which in turn drives a slide to move up and down reciprocally through a clutch and transmission mechanism. This applies pressure to the sheet metal placed in a die, causing it to undergo plastic deformation or separation, thereby obtaining parts of the required shape and size.

[0003] The punch presses currently in use are usually single-linkage structures. During the stamping process, the stamping force is mainly concentrated at the center of the slide, resulting in uneven distribution of stamping force. This can easily lead to workpiece deformation, uneven edges, and other problems. Furthermore, the motion accuracy of the slide is affected by factors such as the length of the connecting rod and the accuracy of the crankshaft, which may cause deviations in the slide's motion trajectory, affecting stamping accuracy and stability.

[0004] Therefore, it is necessary to provide a high-precision, high-strength steel frame punch press with a double-link elbow to solve the above-mentioned technical problems. Utility Model Content

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0034] First Embodiment

[0035] Please refer to the following: Figure 1 , Figure 2 and Figure 5 A high-precision, high-strength steel frame punch press with a toggle-joint double linkage includes: a mounting structure 1, wherein the mounting structure 1 includes a base 11, a support rod 12 and a mounting seat 13, wherein the support rod 12 is mounted on the base 11 and the mounting seat 13 is slidably mounted on the support rod 12;

[0036] Drive device 2, which is installed in the mounting base 13;

[0037] Two sets of transmission components 3 are symmetrically and rotatably mounted on both sides of the mounting base 13 and rotatably connected to the output end of the drive device 2.

[0038] A stamping assembly 4 is rotatably mounted on the transmission assembly 3 and is used to mount processing molds.

[0039] When stamping a workpiece, the stamping die is first installed on the base 11 and the stamping assembly 4 respectively. Both the base 11 and the stamping assembly 4 have mounting slots to limit and fix the die. Then, the workpiece is placed on the lower die on the base 11. The drive device 2 is started, and the stamping assembly 4 is driven to move up and down reciprocally through two sets of transmission components 3. The stamping assembly 4 drives the upper die to move up and down in the vertical direction of the lower die. The upper and lower dies work together to perform stamping operations such as punching and blanking on the workpiece. By setting two sets of transmission components 3, the stamping force is evenly distributed on the stamping assembly 4, which can ensure that the stamping force on all parts of the upper die is consistent, improve the stamping quality, reduce the possibility of workpiece deformation and damage, and at the same time ensure that the upper die has a relatively stable movement trajectory, thereby improving the accuracy and stability of stamping.

[0040] Please refer to the following: Figure 1 and Figure 2 The driving device 2 includes a first motor 21, a first gear 22, a first transmission shaft 23, and a second gear 24. The first motor 21 is installed in the mounting base 13. The first gear 22 is installed at the output end of the first motor 21. The two ends of the first transmission shaft 23 pass through the mounting base 13 and are rotatably connected to the mounting base 13. The second gear 24 is fixedly installed on the first transmission shaft 23, and the second gear 24 meshes with the first gear 22.

[0041] When the stamping operation is performed, the first motor 21 is started, and the output end drives the first gear 22 to rotate. The first gear 22 drives the first transmission shaft 23 to rotate on the mounting base 13 through the second gear 24.

[0042] Please refer to the reference again. Figure 1 and Figure 2 The driving device 2 further includes two driving wheels 25 and two transmission belts 26. The two driving wheels 25 are symmetrically installed at both ends of the first transmission shaft 23, and the two transmission belts 26 are slidably installed on the two driving wheels 25 respectively.

[0043] After the first motor 21 is started, the output end drives the first transmission shaft 23 to rotate through the first gear 22 and the second gear 24. The first transmission shaft 23 drives the drive wheels 25 at both ends to rotate. The drive wheels 25 drive the transmission assembly 3 to rotate through the transmission belt 26. The transmission assembly 3 drives the stamping assembly 4 and the upper mold to move up and down reciprocally to perform stamping operation on the workpiece.

[0044] Please refer to the following: Figure 3 , Figure 4 and Figure 5 The transmission assembly 3 includes a second transmission shaft 31, a transmission wheel 32, and a crankshaft 33. The second transmission shaft 31 passes through the mounting base 13 and is rotatably connected to the mounting base 13. The transmission wheel 32 and the crankshaft 33 are respectively fixedly installed at both ends of the second transmission shaft 31.

[0045] After the first motor 21 is started, the drive wheel 25 drives the transmission wheel 32 to rotate through the transmission belt 26. The transmission wheel 32 drives the second transmission shaft 31 and the crankshaft 33 to rotate. The stamping assembly 4 is rotatably mounted on the crankshaft 33. The two crankshafts 33 apply stamping force to the stamping assembly 4, and the stamping force is evenly applied to the stamping assembly 4 to avoid uneven distribution of stamping force, which would affect the stamping effect of the workpiece.

[0046] Please refer to the reference again. Figure 3 , Figure 4 and Figure 5 The stamping assembly 4 includes a stamping head 41 and two connecting rods 42. The top of the stamping head 41 is rotatably mounted with two connecting rods 42, and the two connecting rods 42 are rotatably connected to the crankshaft 33 respectively.

[0047] Before the stamping operation, the upper die is installed on the stamping head 41. After the first motor 21 is started, the crankshaft 33 drives the connecting rod 42 to rotate. The connecting rod 42 drives the stamping head 41 to move up and down. The two connecting rods 42 drive the stamping head 41 to move, ensuring that the stamping head 41 can maintain a relatively stable motion trajectory when it performs high-speed reciprocating motion, thereby improving the accuracy and stability of stamping.

[0048] Second Embodiment

[0049] Please refer to the following: Figure 6 , Figure 7 and Figure 8 The toggle-joint double-link high-precision and high-strength steel frame punch press also includes a pushing device 5. The base 11 has a discharge groove 111, which is L-shaped. The pushing device 5 is installed in the discharge groove 111.

[0050] When the punch press performs operations such as punching, the waste generated by the stamping process tends to accumulate on the base 11. When there is a lot of waste, it will affect subsequent stamping operations, requiring workers to clean up the waste frequently.

[0051] In this embodiment, the lower mold is installed above the discharge groove 111. After the workpiece is punched, the waste material will fall into the discharge groove 111. The waste material in the discharge groove 111 is pushed out by the pusher device 5 to avoid the waste material from accumulating and affecting the subsequent punching operation.

[0052] Please refer to the following: Figure 7 and Figure 8 The feeding device 5 includes a second motor 51, a threaded rod 52 and a push rod 53. The second motor 51 is installed in the discharge trough 111. The output end of the second motor 51 is equipped with the threaded rod 52, and the push rod 53 is threadedly connected to the surface of the threaded rod 52.

[0053] When the waste material falls into the discharge trough 111, the second motor 51 is started, and the output end drives the threaded rod 52 to rotate. The threaded rod 52 drives the push rod 53 to move forward in the discharge trough 111, pushing the waste material out of the discharge trough 111, thus preventing the waste material from accumulating on the base 11 and affecting the subsequent stamping process.

[0054] Please refer to the following: Figure 1 , Figure 4 and Figure 5 The mounting structure 1 also includes a plurality of guide posts 14, which are symmetrically mounted on the base 11. The stamping head 41 has a plurality of guide holes 43, and the guide holes 43 are adapted to the guide posts 14.

[0055] Before the stamping operation, the guide post 14 is inserted into the guide hole 43 in the stamping head 41. During the stamping operation, the stamping head 41 drives the upper die to move up and down reciprocally. At the same time, the guide hole 43 and the guide post 14 limit the stamping head 41 to ensure that the stamping head 41 moves along a stable trajectory, avoids deviation, and ensures the stability and accuracy of the stamping operation.

[0056] The working principle of the toggle-joint double-link high-precision heavy-duty steel frame punch press provided by this utility model is as follows:

[0057] When stamping a workpiece, the stamping die is first installed on the base 11 and the stamping head 41 respectively. Then, the workpiece is placed on the lower die on the base 11. The first motor 21 is started, and the output end drives the first gear 22 to rotate. The first gear 22 drives the first transmission shaft 23 to rotate on the mounting base 13 through the second gear 24. The first transmission shaft 23 drives the drive wheels 25 at both ends to rotate. The drive wheels 25 drive the transmission wheel 32 to rotate through the transmission belt 26. The transmission wheel 32 drives the second transmission shaft 31 and the crankshaft 33 to rotate. The crankshaft 33 drives the connecting rod 42 to rotate. The connecting rod 42 drives the stamping head 41 and the upper die to move up and down reciprocally. By setting two sets of crankshafts 33 and connecting rods 42, the stamping force is evenly applied to the stamping head 41, avoiding uneven distribution of stamping force, which would affect the stamping effect of the workpiece and improve the stamping quality. At the same time, it ensures that the upper die has a relatively stable movement trajectory, improving the accuracy and stability of stamping. When the scrap material falls into the discharge trough 111, the second motor 51 is started, and the output end drives the threaded rod 52 to rotate. The threaded rod 52 drives the push rod 53 to move forward in the discharge trough 111, pushing the scrap material out of the discharge trough 111 and preventing the scrap material from accumulating on the base 11 and affecting the subsequent stamping process.

[0058] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
