Description

Technical Field

[0001] This utility model relates to the field of metal stamping technology, and in particular to a stamping machine for metal processing. Background Technology

[0002] Metal stamping is a common metal forming process widely used in the manufacture of various metal parts. This process uses a stamping press and dies to plastically deform metal materials (usually thin sheets) under pressure to obtain the desired shape and size. A stamping press is required for metal stamping.

[0003] In the prior art, CN219966127U discloses a convenient metal product processing stamping machine, which includes a worktable. The upper side wall of the worktable has a mold groove. Multiple fixed columns are fixedly connected to the upper side wall of the worktable. A support plate is fixedly connected to the upper ends of the multiple fixed columns. A hydraulic cylinder is fixedly connected to the lower side wall of the support plate. The driving end of the hydraulic cylinder is vertically downward and has a punch installed thereon. A fixed box is fixedly connected to the lower side wall of the worktable. The upper end of the fixed box is open. A lifting plate that slides inside the fixed box and fits against the inner wall of the fixed box is also present. This invention uses the helical movement of a threaded rod to move the punch upward, thereby ejecting the metal product, making it easy to handle, saving time and effort, and improving work efficiency.

[0004] However, the device still has some problems. For example, by placing the metal products to be stamped in the die groove of the worktable for stamping, the fixed size of the die groove makes it impossible to center the raw materials of different sizes of metal products during actual use. This may cause the stamping position to shift, resulting in a reduction in the stamping quality. Therefore, we disclose a metal processing stamping machine to meet people's needs. Utility Model Content

[0005] The purpose of this application is to provide a stamping machine for metal processing, so as to solve the problem mentioned in the background art that the fixed die groove size cannot be used to center the raw materials of different sizes of metal products, which may lead to the stamping position displacement and the reduction of stamping quality.

[0006] To achieve the above objectives, this application provides the following technical solution: a metal processing stamping machine, including a placement table, a bracket fixedly installed on the upper side of the placement table, a hydraulic cylinder for stamping parts fixedly installed on the bracket, and an installation groove opened on the upper side of the placement table, in which a positioning component for fixing the processed parts is slidably installed;

[0007] The positioning component includes a placement plate that is slidably installed in a mounting groove. The upper side of the placement plate has multiple limiting holes, and each of the multiple limiting holes has a movable block slidably installed in it. Each of the multiple movable blocks has a positioning block fixedly installed on its upper side. The lower side of the placement plate has a drive unit that is rotatably installed to facilitate driving the positioning blocks.

[0008] Preferably, the drive unit includes a threaded rod, which is rotatably mounted on the lower side of the placement plate. A drive disk is fixedly mounted on the non-threaded area of ​​the surface of the threaded rod. The upper side of the drive disk has multiple arc-shaped grooves, and the lower sides of the multiple moving blocks are correspondingly slidably mounted in the arc-shaped grooves.

[0009] Preferably, the drive unit further includes a fixing plate, and the inner bottom wall of the mounting groove is provided with a motor port. The fixing plate is fixedly installed in the motor port and screwed onto the threaded area of ​​the threaded rod surface.

[0010] Preferably, a heat sink is fixedly installed inside the motor port, a drive motor is fixedly installed on the upper side of the heat sink, a drive rod is fixedly installed at the output end of the drive motor, a drive hole is opened at the bottom end of the threaded rod, and the drive rod is slidably installed in the drive hole.

[0011] Preferably, an air chamber is provided on the upper side of the placement platform, a piston is slidably installed in the air chamber, a sealing plate is fixedly installed on the inner wall of the air chamber, an air inlet is provided on the upper side of the sealing plate, an air inlet pipe is fixedly installed in the air inlet, a one-way valve is fixedly installed on the air inlet pipe, the one-way valve is directed from the air inlet pipe to the air chamber, an air outlet is provided on the upper side of the sealing plate, a cleaning pipe is fixedly installed in the air outlet, a one-way valve is fixedly installed on the cleaning pipe, the one-way valve is directed from the air chamber to the cleaning pipe, and a heat dissipation channel communicating with the motor port is provided on the inner bottom wall of the air chamber.

[0012] Preferably, a fixing rod is fixedly installed on the output shaft surface of the hydraulic cylinder, and a connecting column is fixedly installed at the top end of the fixing rod. The connecting column is fixedly connected to the upper side of the piston, and the connecting column is slidably installed on the sealing plate.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. In this utility model, the metal material to be processed is placed on the placement plate. By starting the drive motor, the output end of the drive motor drives the drive rod to rotate, the drive rod drives the threaded rod to rotate, the threaded rod drives the drive disc to rotate, and the drive disc drives multiple moving blocks to move under the action of the limiting port. The multiple moving blocks drive the corresponding positioning blocks to move closer to each other, thereby positioning the metal material. At the same time, when the threaded rod rotates, the limiting action of the fixed plate drives the threaded rod to move downward, and the threaded rod drives the placement plate to move downward, causing the metal material to descend and shrink into the placement groove, which is convenient for the hydraulic cylinder to perform stamping processing. This achieves the effect of fixing the processed metal material and improving the processing quality.

[0015] 2. In this utility model, the hydraulic cylinder output shaft moves downward, which drives the fixed rod to move downward. The fixed rod drives the connecting column to move downward, and the connecting column drives the piston to move downward. The piston creates negative pressure in the air chamber, drawing air in through the air inlet pipe. At the same time, the air in the air chamber below the piston is discharged into the motor port through the heat dissipation channel to cool the drive motor. After the stamping is completed, the hydraulic cylinder output shaft rises, driving the piston upward, causing the air in the air chamber to be sprayed out from the cleaning pipe to clean the surface of the stamped metal material, removing metal debris and preventing it from affecting the quality of the next stamping.

Detailed Implementation

[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. 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.

[0023] Please see Figures 1-4 The embodiments provided by this utility model are as follows:

[0024] A metal processing stamping machine includes a placement table 1, a bracket 2 fixedly installed on the upper side of the placement table 1, and a hydraulic cylinder 3 for stamping parts fixedly installed on the bracket 2. The hydraulic cylinder 3 is prior art and is equipped with a corresponding power source to perform stamping. A stamping block is installed at the output end of the hydraulic cylinder 3. An installation groove is opened on the upper side of the placement table 1, and a positioning component for fixing the processed parts is slidably installed in the installation groove.

[0025] The positioning component includes a placement plate 4, which is slidably installed in a mounting groove. Multiple limiting holes are provided on the upper side of the placement plate 4, including four perpendicular ones. Moving blocks 5 are slidably installed within each limiting hole. Positioning blocks 6 are fixedly installed on the upper side of each moving block 5. A drive unit for driving the positioning blocks 6 is rotatably installed on the lower side of the placement plate 4. The drive unit includes a threaded rod 8, which is rotatably installed on the lower side of the placement plate 4. A drive disc 9 is fixedly installed on the non-threaded area of ​​the surface of the threaded rod 8. Multiple arc-shaped grooves are provided on the upper side of the drive disc 9, the number of which matches the number of limiting holes. This facilitates the driving of the moving blocks 5. The lower sides of the multiple moving blocks 5 are correspondingly slidably installed in the arc-shaped groove. The bottom end of the moving blocks 5 is round, which facilitates the sliding installation in the arc-shaped groove. The driving unit also includes a fixing plate 7. The inner bottom wall of the mounting groove has a motor port. The fixing plate 7 is fixedly installed in the motor port. The fixing plate 7 is screwed onto the threaded area on the surface of the threaded rod 8. When the threaded rod 8 rotates, the fixing plate 7 will cause the threaded rod 8 to move up and down. When fixing the stamping material, it is necessary to ensure that after the material is positioned, its multiple positioning blocks 6 move to the closest distance so that the driving disk 9 fits against the inner bottom wall of the mounting groove to prevent the threaded rod 8 from being deformed by force.

[0026] like Figure 2 and Figure 3 As shown, a heat sink 10 is fixedly installed inside the motor port, and a drive motor 11 is fixedly installed on the upper side of the heat sink 10. A drive rod 12 is fixedly installed at the output end of the drive motor 11. A drive hole is opened at the bottom end of the threaded rod 8, and the drive rod 12 is slidably installed in the drive hole. The drive motor 11 is a servo motor that can rotate in both directions. The drive rod 12 has a hexagonal cross-section and is slidably installed in the drive hole. While driving the threaded rod 8 to rotate, it will not affect the up and down movement of the threaded rod 8.

[0027] When the device is in use, the metal material to be processed is placed on the placement plate 4. By starting the drive motor 11, the output end of the drive motor 11 drives the drive rod 12 to rotate, the drive rod 12 drives the threaded rod 8 to rotate, the threaded rod 8 drives the drive disc 9 to rotate, and the drive disc 9 drives multiple moving blocks 5 to move under the action of the limiting port. The multiple moving blocks 5 drive the corresponding positioning blocks 6 to move closer to each other, thereby positioning the metal material. At the same time, when the threaded rod 8 rotates, the limiting action of the fixed plate 7 drives the threaded rod 8 to move downward, and the threaded rod 8 drives the placement plate 4 to move downward, so that the metal material descends and retracts into the placement groove. The hydraulic cylinder 3 is then started to stamp the metal material.

[0028] like Figure 2 As shown, an air chamber is provided on the upper side of the placement platform 1. A piston 15 is slidably installed inside the air chamber. A sealing plate 16 is fixedly installed on the inner wall of the air chamber. An air inlet is provided on the upper side of the sealing plate 16. An air inlet pipe 17 is fixedly installed inside the air inlet. A one-way valve is fixedly installed on the air inlet pipe 17, with the one-way valve pointing from the air inlet pipe 17 to the air chamber. An air outlet is provided on the upper side of the sealing plate 16. A cleaning pipe 18 is fixedly installed inside the air outlet. A one-way valve is fixedly installed on the cleaning pipe 18, with the one-way valve pointing from the air chamber to the cleaning pipe 18. A heat dissipation channel 19 connected to the motor port is provided on the inner bottom wall of the air chamber. The output shaft of the hydraulic cylinder 3 moves downward. The output shaft of the hydraulic cylinder 3 carries... The fixed rod 13 moves downward, which drives the connecting column 14 to move downward. The connecting column 14 drives the piston 15 to move downward. The piston 15 creates negative pressure in the air chamber and draws in air through the air inlet pipe 17. At the same time, the air in the air chamber below the piston 15 is discharged into the motor port through the heat dissipation channel 19 to cool the drive motor 11. After the stamping is completed, the output shaft of the hydraulic cylinder 3 rises, driving the piston 15 to move upward. This causes the air in the air chamber to be sprayed out from the cleaning pipe 18 to blow air and clean the surface of the stamped metal material, removing metal debris and preventing it from affecting the quality of the next stamping.

[0029] like Figure 3As shown, a fixing rod 13 is fixedly installed on the output shaft surface of the hydraulic cylinder 3, and a connecting column 14 is fixedly installed on the top end of the fixing rod 13. The connecting column 14 is fixedly connected to the upper side of the piston 15, and the connecting column 14 is slidably installed on the sealing plate 16.

[0030] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
