Description

Technical Field

[0001] This utility model belongs to the technical field of evaporators, and in particular relates to a plate punching processing equipment for evaporators. Background Technology

[0002] The evaporator is one of the core components of a refrigeration system, primarily used for heat exchange, achieving a cooling effect by absorbing heat through liquid evaporation. The main function of the evaporator is to convert liquid refrigerant into a gaseous state, absorbing heat from the surrounding environment to lower the temperature, thus achieving a cooling effect. Evaporator: Liquid refrigerant absorbs heat and vaporizes here, lowering the ambient temperature; Condenser: Gaseous refrigerant releases heat and liquefies here, raising the ambient temperature. Evaporators are composed of fins, pipes, etc. The fins, outer frame, and other sheet metal need to pass through the pipes, requiring punching operations on the corresponding sheet metal. This necessitates appropriate punching equipment, but the following drawbacks still exist in actual punching operations: Firstly, for the punching operation of evaporator plates, the holes are usually punched directly on the surface of the plate. However, during normal punching operations, the punch head presses against the plate. At this time, the plate is generally not under pressure. Under the state of direct punching, firstly, it is easy to cause punching deviation. Secondly, after punching, the plate may vibrate and bounce slightly, causing deviation of the subsequent punching position. Therefore, there is no corresponding clamping structure during punching. Secondly, the large amount of small waste generated by stamping can easily accumulate or get stuck in the punch head and cannot fall out, which can easily affect subsequent punching operations. Finally, for evaporators of different sizes, the location and diameter of the punch holes on the plate are not consistent, which requires replacing the corresponding punch head and changing its position. Utility Model Content

[0003] The purpose of this utility model is to provide a plate punching processing equipment for evaporators. By setting up a pressure frame, a clamping frame, a limiting rod, a spring, a base, a hydraulic cylinder, a punching beam, a cross block, a Y-shaped air pipe, a punching head, and a shaft, it solves the problems of lack of auxiliary clamping function during punching, small waste materials generated during punching getting stuck in the punching head, and the inability to quickly replace the punching head and change the punching position.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a plate punching processing equipment for evaporators, including a base, a hydraulic cylinder, a pressure frame, a clamping basket, and a punching beam. A top plate is provided directly above the base. A vertical plate is fixed to the back of the base and the top plate. A hydraulic cylinder is fixed to the top of the top plate. A pressure frame and a clamping frame are arranged sequentially from top to bottom between the top plate and the base. A punching beam is fixed in the inner cavity of the pressure frame. Limiting ring 1 is fixed to each of the four corners of the pressure frame. Limiting ring 2 is fixed to each of the four corners of the clamping frame. A clamping spring is fixed between the limiting ring 1 and the limiting ring 2, which are on the same central axis. The lower inner part of the punched beam is provided with a cross groove, and a second shaft is rotatably connected in the cross groove. The second shaft is provided with two sections of threads in opposite directions. Each section of the thread of the second shaft is threaded with a cross block that is slidably connected to the cross groove. A punching head is provided below each cross block.

[0005] Furthermore, the base is provided with an adjustment groove, and a shaft is rotatably connected in the adjustment groove. The shaft is provided with two sections of threads in opposite directions, and an adjustment block is threadedly connected to each section of the thread. An angle plate is fixed on each adjustment block, and the angle plates on the two adjustment blocks are symmetrically arranged. The end of the shaft away from the vertical plate extends through the base and is fixed with a handwheel.

[0006] Furthermore, four limiting rods arranged in a rectangular pattern are fixed between the top plate and the base, and limiting ring one, limiting ring two, and compression spring, which are on the same central axis, are all sleeved on one limiting rod.

[0007] Furthermore, the lower part of the perforated beam extends beyond the bottom surface of the pressure frame, and two symmetrical through slots are opened in the upper inner part of the perforated beam. The through slots and the cross slot are connected. The piston rod of the telescopic end of the hydraulic cylinder passes through the top plate and is fixedly connected to the top center of the perforated beam.

[0008] Furthermore, both ends of the second shaft extend beyond the lower ends of the punched beam, and a handwheel is fixed to the end of the second shaft away from the vertical plate.

[0009] Furthermore, an internal threaded ring is fixed to the bottom surface of the cross block, and an external threaded ring is fixed to the upper end of the punch head, with the external threaded ring on the punch head screwed into the internal threaded ring.

[0010] Furthermore, a Y-shaped air tube is connected through the two cross blocks, and the Y-shaped air tube communicates with the interior of the internal threaded ring.

[0011] This utility model has the following beneficial effects: This invention solves the problem of lacking auxiliary clamping function during punching by setting up a pressure frame, a clamping frame, a limiting rod, a spring, a base, and a hydraulic cylinder. During punching, the sheet metal is placed on the base, the hydraulic cylinder operates, driving the punching beam to descend, which in turn lowers the pressure frame, causing it to descend synchronously until the clamping frame contacts the sheet metal. As the pressure frame continues to descend, the spring is compressed, at which point the clamping frame tightly presses down on the sheet metal. Figures 1 to 2 This state prevents the sheet material from loosening, facilitating subsequent punching operations and preventing the sheet material from shifting during punching.

[0012] This invention solves the problem of small waste materials getting stuck in the punching head by setting up a punching beam, a cross block, a Y-shaped air pipe, and a punching head. During punching, the punching beam descends, driving the cross block and the punching head to descend until the punching head punches out the corresponding hole. Then, the hydraulic cylinder controls the punching beam to return to its original position. At this time, the Y-shaped air pipe is connected to an external air source to blow air into the punching head, causing the stuck small waste materials to be blown out, avoiding blockage and affecting the next use.

[0013] This invention solves the problem of not being able to quickly replace the punch head and change the punching position by setting up a punching beam, a cross block, and a second shaft. When it is necessary to replace the punch head, simply unscrew the external threaded ring at the top of the punch head from the internal threaded ring at the bottom of the cross block to replace it with a new punch head. When it is necessary to change the punching position, rotate the second shaft to move the two cross blocks closer or further apart, thereby changing the position of the two punch heads and changing the position and spacing of the punches.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Please see Figure 1-6 As shown, this utility model is a plate punching processing equipment for evaporators, including a base 1, a hydraulic cylinder 2, a pressure frame 3, a clamping basket and a punching beam 7. A top plate 102 is provided directly above the base 1. A vertical plate 101 is fixed to the back of the base 1 and the top plate 102. A hydraulic cylinder 2 is fixed to the top of the top plate 102. A pressure frame 3 and a clamping frame 4 are arranged from top to bottom between the top plate 102 and the base 1. A punching beam 7 is fixed in the inner cavity of the pressure frame 3. Limiting rings 301 are fixed at all four corners of the pressure frame 3. Limiting rings 401 are fixed at all four corners of the clamping frame 4. A clamping spring 5 is fixed between the limiting rings 301 and 401 which are on the same central axis. The main frame, consisting of base 1, top plate 102, and vertical plate 101, serves as the carrier for installation and punching. The sheet metal to be punched is placed on base 1. Then, hydraulic cylinder 2 operates, driving punch beam 7 to descend, which in turn lowers pressure frame 3, causing clamping frame 4 to descend synchronously until it contacts the sheet metal. As pressure frame 3 continues to descend, the spring is compressed, at which point clamping frame 4 tightly presses the sheet metal (forming a pressure plate). Figures 1 to 2 (as shown in the image) prevents the sheet metal from loosening, facilitating subsequent punching operations; The lower inner part of the punch beam 7 is provided with a cross groove 702. A shaft 704 is rotatably connected in the cross groove 702. The shaft 704 is provided with two threads in opposite directions. Each thread of the shaft 704 is threadedly connected with a cross block 703 that is slidably connected to the cross groove 702. A punch head 8 is provided below each cross block 703. When the second shaft 704 is rotated, the two sections of threads with opposite directions on the second shaft 704 cause the two cross blocks 703 to move closer or further apart in the cross groove 702, thereby changing the position of the two punch heads 8 and changing the position and spacing of the punches.

[0019] The base 1 has an adjustment groove 104, and a shaft 6 is rotatably connected in the adjustment groove 104. The shaft 6 has two threads in opposite directions, and an adjustment block 601 is threadedly connected to each thread of the shaft 6. An angle plate 602 is fixed on each adjustment block 601, and the angle plates 602 on the two adjustment blocks 601 are symmetrically arranged. The end of the shaft 6 away from the vertical plate 101 extends through the base 1 and is fixed with a handwheel. When placing the plate, first place one end between the two corner plates 602. Then, rotate the shaft 6 by handwheel. Because of the two sections of opposite threads on the shaft 6, the two adjusting blocks 601 and the corner plates 602 above them move closer or further apart until the two corner plates 602 clamp the plate, thus centering the plate. The other end of the plate is connected to the feeding or ejection equipment, etc.

[0020] Four limiting rods 103 arranged in a rectangular pattern are fixed between the top plate 102 and the base 1. The limiting ring 301, the limiting ring 401, and the compression spring 5, which are on the same central axis, are all sleeved on the outside of a limiting rod 103. The limit rod 103 is set inside the limit ring 301, the limit ring 401, and the clamping spring 5, so that there will be no excessive deviation when the pressure frame 3 and the clamping frame 4 are raised and lowered, making the operation of the hydraulic cylinder 2 more stable and the punching position more accurate.

[0021] The lower part of the punched beam 7 extends beyond the bottom surface of the pressure frame 3, and two symmetrical through slots 701 are opened in the upper inner part of the punched beam 7. The through slots 701 and the cross slots 702 are connected. The piston rod of the telescopic end of the hydraulic cylinder 2 passes through the top plate 102 and is fixedly connected to the top center of the punched beam 7. Both ends of the shaft 704 extend out of the lower ends of the punched beam 7, and a handwheel is fixed to the end of the shaft 704 away from the vertical plate 101. The punched beam 7 is installed at the center of the pressure frame 3, and its lower part and shaft 2 704 extend out of the pressure frame 3. The hydraulic cylinder 2 is connected to the punched beam 7 to make it rise and fall. By rotating the corresponding shaft 2 704 through the handwheel, the position of the cross block 703 is changed. The design of the cross groove 702 and the through groove 701 facilitates the extension of the Y-shaped air pipe 705.

[0022] An internal threaded ring 7031 is fixed to the bottom surface of the cross block 703, and an external threaded ring 801 is fixed to the upper end of the punch head 8. The external threaded ring 801 on the punch head 8 is screwed into the internal threaded ring 7031. When the punch head 8 needs to be replaced, the external threaded ring 801 at its upper end can be unscrewed from the internal threaded ring 7031 at the bottom of the cross block 703, and a new punch head 8 can be replaced. A Y-shaped air tube 705 is connected through the two cross blocks 703, and the Y-shaped air tube 705 is connected to the inside of the internal threaded ring 7031; the Y-shaped air tube 705 is connected to an external air source to blow air into the punch head 8, so that the small waste material stuck is blown out, avoiding blockage and affecting the next use.

[0023] The specific working principle of this utility model is as follows: First, the plate to be punched is placed on the base 1, with one end positioned between two corner plates 602. Then, by rotating the first shaft 6 with a handwheel, the two adjusting blocks 601 and the corner plates 602 above them move closer or further apart due to the two opposing threads on the first shaft 6, until the two corner plates 602 clamp the plate, thus centering the plate. Next, by rotating the corresponding second shaft 704 with a handwheel, the two cross blocks 703 move closer or further apart within the cross grooves 702 due to the two opposing threads on the second shaft 704, thereby changing the position of the two punch heads 8. After determining the punching position... The hydraulic cylinder 2 drives the punching beam 7 to descend, which in turn lowers the pressure frame 3, causing the clamping frame 4 to descend synchronously until it contacts the plate. As the pressure frame 3 continues to descend, the spring is compressed, and the clamping frame 4 tightly presses the plate, preventing it from loosening, until the punching head 8 punches out the corresponding hole. Then, the hydraulic cylinder 2 controls the punching beam 7 to return to its original position. At this time, the Y-shaped air pipe 705 is connected to an external air source to blow air into the punching head 8, causing the stuck small waste material to be blown out, completing the punching operation. When the punching head 8 needs to be replaced, the external threaded ring 801 at its upper end is unscrewed from the internal threaded ring 7031 at the bottom of the cross block 703, and a new punching head 8 can be replaced.

[0024] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
