[0002] A stamping press, also known as a punch press, is an industrial equipment mainly used for processing metal sheets. It uses molds and pressure to deform the metal sheets, thereby manufacturing parts of various shapes and structures. Its working principle is that the cylinder drives the push rod mechanism to generate pressure, which applies pressure to the material to plastically deform it, thereby obtaining the workpiece with the required shape and precision.

[0003] When a stamping press processes metal sheets, it is necessary to form the workpiece according to the requirements by stamping with an upper die and a lower die. However, in the existing stamping press, the stamped workpiece is stuck on the surface of the upper die during the processing. When the workpiece is removed from the upper die, it needs to be done manually, which can cause workers to spend a lot of time and effort due to frequent operation, and affect the normal removal of the workpiece. Utility Model Content

[0004] The purpose of this utility model is to provide a stamping machine that facilitates the removal of workpieces, in order to solve the problem mentioned in the background art that, during the processing of stamping machines, the stamped workpiece is stuck on the surface of the upper mold, and when the workpiece is removed from the upper mold, it needs to be done manually, which easily causes workers to spend a lot of time and effort with frequent operations, affecting the normal removal of workpieces.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamping machine for easy removal of workpieces, comprising a mounting frame, a controller and a cylinder fixedly connected to the outer surface of the mounting frame, a lower die, a support plate and a mounting chamber fixedly connected to the inner surface of the mounting frame, a push rod mounted on the surface of the cylinder, an upper die fixedly connected to the surface of the push rod, a workpiece body engaged with the surface of the upper die, a reversible motor fixedly connected to the surface of the support plate, an output shaft mounted on the surface of the reversible motor, a movable plate fixedly connected to the surface of the output shaft, a collection box abutting against the inner surface of the mounting frame, a connecting hole on one side of the mounting chamber, a through hole on the other side of the mounting chamber, a partition plate mounted on the inner surface of the mounting chamber, a support spring and a pull rod fixedly connected to one side of the partition plate, a plug-in block fixedly connected to the other side of the partition plate, and a plug-in hole on the surface of the collection box.

[0006] Preferably, the support plate has an "I" shaped cross-section, one end of the support plate is fixedly connected to the inner surface of the mounting frame, and the other end of the support plate is fixedly connected to the surface of the reversible motor.

[0007] Preferably, one end of the output shaft is rotatably connected to the surface of the reversible motor, the other end of the output shaft is mounted on the surface of the movable plate, and the cross-section of the output shaft is circular.

[0008] Preferably, the side of the collection box is a right-angled trapezoid, and two sets of installation compartments are provided. The two sets of installation compartments are fitted and connected to both sides of the collection box. The partition is slidably connected to the inner surface of the installation compartment, and the size of the partition is larger than the size of the connection hole.

[0009] Preferably, there are two sets of support springs, which are installed on both sides of the pull rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By installing a reversible motor on the inner surface of the mounting frame, the reversible motor can drive the movable plate to rotate forward and backward around the output shaft. When the movable plate rotates to the upper mold side, it can push the workpiece body and remove it from the surface of the upper mold, thus avoiding the need for workers to manually remove the workpiece body from the upper mold. At the same time, the removed workpiece body falls into the collection box for collection. When a certain amount is collected, it can be removed together, making the removal of the workpiece body more convenient and labor-saving, reducing manual operation and improving work efficiency.

[0014] 2. By setting installation compartments on both sides of the collection box and attaching them to its surface, the support springs installed in the installation compartments can apply support force to the surface of the partition, thereby making the connection between the plug block and the connecting hole more secure and stable, so as to achieve the effect of fixing the position of the collection box and preventing position displacement during collection. At the same time, the action of the pull rod makes the assembly and disassembly of the collection box more convenient and quick. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A stamping machine for easy workpiece removal includes a mounting frame 1. A controller 2 and a cylinder 3 are fixedly connected to the outer surface of the mounting frame 1. A lower die 6, a support plate 8, and a mounting chamber 13 are fixedly connected to the inner surface of the mounting frame 1. A push rod 4 is mounted on the surface of the cylinder 3, and an upper die 5 is fixedly connected to the surface of the push rod 4. A workpiece body 7 is engaged with the surface of the upper die 5. A reversible motor 9 is fixedly connected to the surface of the support plate 8, and an output shaft 10 is mounted on the surface of the reversible motor 9. A movable plate 11 is fixedly connected to the surface of the output shaft 10. A collection box 12 is abutted against the inner surface of the mounting frame 1. A connecting hole 17 is opened on one side of the mounting chamber 13, and a through hole 19 is opened on the other side of the mounting chamber 13. A partition is installed on the inner surface of the mounting chamber 13. A support spring 15 and a pull rod 20 are fixedly connected to one side of the plate 14 and a plug block 16 is fixedly connected to the other side of the plate 14. The surface of the collection box 12 is provided with a plug hole 18. When processing the workpiece, the workpiece body 7 is first placed on the lower mold 6 and positioned directly below the upper mold 5. The operation controller 2 issues a command to make the cylinder 3 drive the push rod 4 to move to the side of the lower mold 6. Then, the workpiece body 7 is formed into the required shape under the pressure of the lower mold 6 and the upper mold 5. At this time, the workpiece body 7 is locked on the upper mold 5 and moved to the outside of the lower mold 6. The reversible motor 9 is a special type of motor that can rotate in both directions and transmit power. It is an existing device and will not be described in detail here.

[0024] Furthermore, the cross-section of the support plate 8 is in the shape of an "I". One end of the support plate 8 is fixedly connected to the inner surface of the mounting frame 1, and the other end of the support plate 8 is fixedly connected to the surface of the reversible motor 9. Under the action of the support plate 8, the reversible motor 9 can be supported, and the movable plate 11 can be at the height to push the processed workpiece body 7 after rotation.

[0025] Furthermore, one end of the output shaft 10 is rotatably connected to the surface of the reversible motor 9, and the other end of the output shaft 10 is mounted on the surface of the movable plate 11. The cross-section of the output shaft 10 is circular. Under the action of the reversible motor 9, the output shaft 10 can be driven to rotate in both directions, thereby driving the movable plate 11 to return to its initial position after pushing the workpiece body 7. The reversible motor 9 is connected to and controlled by an external power source. The edge of the movable plate 11 away from the reversible motor 9 is aligned with the edge of the workpiece body 7 to avoid obstruction during pushing.

[0026] Furthermore, the side of the collection box 12 is a right-angled trapezoid, and two sets of installation chambers 13 are provided. The two sets of installation chambers 13 are fitted and connected to the two sides of the collection box 12. The partition 14 is slidably connected to the inner surface of the installation chamber 13. The size of the partition 14 is larger than the size of the connection hole 17. The collection box 12 can better collect the pushed-out workpiece body 7. The installation chamber 13 can realize the installation limit of the collection box 12. Under the action of the partition 14, the support spring 15 and the pull rod 20 can be installed and the insertion block 16 can be limited to prevent the insertion block 16 from moving out of the installation chamber 13.

[0027] Furthermore, two sets of support springs 15 are provided, and the two sets of support springs 15 are installed on both sides of the pull rod 20. One end of the support spring 15 is fixedly connected to the inner surface of the installation chamber 13, and the other end of the support spring 15 is fixedly connected to the surface of the partition 14. Under the action of the support spring 15, a supporting force can be applied to the surface of the partition 14 to push the partition 14 and the plug block 16 to always have a tendency to move towards the collection box 12.

[0028] Furthermore, the cross-section of the plug-in block 16 is rectangular. One side of the plug-in block 16 is movably connected to the surface of the connecting hole 17, and the other side of the plug-in block 16 is inserted into the surface of the plug-in hole 18. The dimensions of the connecting hole 17 and the plug-in hole 18 are the same. With the connection of the plug-in block 16, the connecting hole 17, and the plug-in hole 18, the connection of the two sets of installation compartments 13 and the collection box 12 can be realized, so as to achieve the effect of limiting and fixing the collection box 12 to the inner surface of the mounting frame 1. The cross-sectional dimensions of the plug-in block 16, the connecting hole 17, and the plug-in hole 18 are all the same.

[0029] Furthermore, two sets of insertion holes 18 are provided, with the two sets of insertion holes 18 located on both sides of the collection box 12. The diameter of the through hole 19 is the same as the diameter of the pull rod 20. The pull rod 20 is slidably connected to the surface of the through hole 19. The insertion hole 18 can be used to install the insertion block 16. The pull rod 20 is movably connected to the surface of the installation chamber 13 through the through hole 19. Pulling the pull rod 20 can move the partition 14, the support spring 15, and the insertion block 16 together.

[0030] Working principle: After the stamping machine finishes processing the workpiece body 7, the reversible motor 9 is first connected to the power supply and started to drive the output shaft 10 and the movable plate 11 to rotate towards the mold 5. The edge of the movable plate 11 away from the reversible motor 9 abuts against the workpiece body 7 and pushes it to fall into the collection box 12. Then the reversible motor 9 is started again to make the movable plate 11 rotate and return to its original position. When the collection box 12 has collected the workpiece body 7 at its maximum capacity, the pull rod 20 is pulled to slide in the through hole 19, so that the partition plate 14 slides in the inner side of the mounting chamber 13. The support spring 15 is in a compressed state, and the plug block 16 moves into the mounting chamber 13 through the connection hole 17 to cancel the engagement between the plug block 16 and the plug hole 18. Then the collection box 12 filled with workpiece body 7 can be taken out from the mounting frame 1.
