DETAILED DESCRIPTION OF THE EMBODIMENTS
[0012] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0013] In the embodiment, given by Figure 1-4 a stamping device for heat exchanger production includes a chassis 1. A mounting plate 2 is fixedly connected to the top end of the chassis 1. A top frame 3 is fixedly connected to the top end of the mounting plate 2. A stamping mechanism 4 is provided at the top end of the top frame 3. A lateral movement mechanism 5 is provided at the top end of the mounting plate 2. The top end of the lateral movement mechanism 5 is fixedly connected to a stamping bottom plate 6. An inclined plane guiding mechanism 7 for the stamping mechanism 4 to perform stamping and forming is provided at the top end of the stamping bottom plate 6.
[0014] With the above setup, the metal sheet to be processed (usually stainless steel coil) is conveyed to the stamping base plate 6 via the transverse moving mechanism 5. The sheet is then fixed on both sides by a clamping device (the clamping device is existing technology known to those skilled in the art; any device capable of performing the clamping action is acceptable) to prevent displacement. The inclined guide mechanism 7 guides the sheet precisely into the stamping station via its inclined surface, ensuring accurate stamping starting position. The stamping mechanism 4 and the inclined guide mechanism 7 act on the sheet to complete the outer stamping process of the heat exchange plate. After stamping, the upper die set is reset, and the correction block releases the sheet under the action of the return spring. The stamping base plate 6 is reset to its initial position via the transverse moving mechanism 5, and the feeding device automatically feeds in a new sheet, starting the next stamping cycle.
[0015] Reference Figure 1-4 The stamping mechanism 4 includes a hydraulic cylinder 41. The left end of the top frame 3 is fixedly connected to the hydraulic cylinder 41. The output end of the hydraulic cylinder 41 is fixedly connected to the card seat 42. The card seat 42 is provided with a card groove 43. The inner side of the card groove 43 is engaged with a lower pressure plate 44. The bottom end of the lower pressure plate 44 is fixedly connected to two lower pressure crossbars 45. With the above structural setup, hydraulic cylinder 41 is activated, and hydraulic pump pressurizes and delivers hydraulic oil (not shown in the figure) into the hydraulic cylinder, pushing the piston rod out and causing the card holder 42 and lower pressure plate 44 to rise to a preset height (to avoid interfering with the placement of the plate). The piston rod of hydraulic cylinder 41 quickly presses down, driving the lower pressure plate 44 downward through the card slot 43 of card holder 42. The two downward pressing crossbars 45 at the bottom of the lower pressure plate 44 act synchronously on the surface of the plate, completing the stamping (such as grooving) under the stable pressure of the hydraulic system, ensuring the forming accuracy. After stamping is completed, the piston rod of hydraulic cylinder 41 retracts, causing the lower pressure plate 44 to rise and reset. The lateral moving mechanism 5 moves the stamping base plate 6 laterally out, and the formed heat exchange plate automatically slides down to the collection area through the inclined groove of the inclined guide mechanism 7, preparing for the next cycle.
[0016] Reference Figure 1-4 The transverse moving mechanism 5 includes a fixed plate 51. The top of the mounting plate 2 is fixedly connected to the fixed plate 51. Slide bars 52 are fixedly connected to both the front and rear ends of the fixed plate 51. Two sliders 53 are slidably connected to the outer sides of the two slide bars 52. The top ends of the four sliders 53 are fixedly connected to the stamping base plate 6. The top of the base frame 1 is fixedly connected to the fixed seat 54. A cylinder 55 is fixedly connected to the inner side of the fixed seat 54. A cylinder push rod 56 is slidably connected to the inner side of the cylinder 55. The cylinder push rod 56 is fixedly connected to the right end of the stamping base plate 6. With the above structural arrangement, the cylinder 55 is in a contracted state, the cylinder ejector rod 56 is fully retracted, and the stamping bottom plate 6 is at the rightmost initial position (close to the fixed seat 54). The stamping bottom plate 6 is slidably connected to the slide bars 52 on both sides of the fixed plate 51 through four sliders 53. At this time, the sliders 53 are closely attached to the limit blocks at the right ends of the slide bars 52 to ensure that the position is reset to zero. The cylinder 55 is inflated and pressurized to push the cylinder ejector rod 56 to extend leftward. The cylinder ejector rod 56 is directly fixed to the right end of the stamping bottom plate 6 to transmit the thrust to the stamping bottom plate 6. The stamping bottom plate 6 slides leftward synchronously along the two parallel slide bars 52 through the four sliders 53. When the cylinder ejector rod 56 is fully extended, the stamping bottom plate 6 reaches the left stamping station, and at this time, the workpiece is directly opposite the stamping head of the stamping mechanism 4. The stamping mechanism 4 presses down to complete the stamping action. During this period, the cylinder 55 maintains a constant pressure and applies a reverse supporting force to the stamping bottom plate 6 through the cylinder ejector rod 56 to prevent displacement caused by stamping vibration. The rigid cooperation between the slide bars 52 and the sliders 53 further suppresses horizontal shaking and ensures the stamping position accuracy. After stamping, the cylinder 55 is depressurized, and the cylinder ejector rod 56 retracts under the action of the return spring or air pressure difference,带动 the stamping bottom plate 6 to slide back to the initial position along the slide bars 52. During the reset process, the self-lubricating characteristics of the sliders 53 and the slide bars 52 reduce wear and ensure long-term repeated positioning accuracy.
[0017] Refer to Figure 1-4 , in which, the inclined plane guiding mechanism 7 includes a heightening plate 71. Two heightening plates 71 are fixedly connected to the top end of the stamping bottom plate 6. The top ends of the two heightening plates 71 are both fixedly connected to the top plate 72. The top end of the top plate 72 is fixedly connected with a "冂"-shaped protrusion 73 adapted to the two downward pressing cross bars 45. The inner side surface of the "冂"-shaped protrusion 73 is an inclined plane; With the above structural arrangement, the metal sheet is placed on the "冂"-shaped protrusion 73. The hydraulic cylinder 41 of the stamping mechanism 4 is started, and the piston rod带动 the lower pressing plate 44 and the downward pressing cross bars 45 to rise to the preparatory height to avoid interfering with the placement of the sheet. The hydraulic cylinder 41 drives the lower pressing plate 44 to move downward, and the two downward pressing cross bars 45 simultaneously contact the surface of the sheet. The inclined plane of the "冂"-shaped protrusion 73 plays a guiding role in the initial stage of stamping: the inclined plane forces the sheet to gather towards the center when being pressed. The downward pressing cross bars 45 continuously apply pressure, and the sheet undergoes plastic deformation and begins to fill the mold cavity (such as the corrugations or grooves required for the heat exchange plate).
