Description

Technical Field

[0001] This utility model relates to the field of punch press technology, specifically a punch press for scrap iron processing. Background Technology

[0002] In the fields of industrial production and waste recycling, scrap iron is an important recyclable resource. Its recycling process often requires compression, shaping or cutting operations through equipment such as punch presses to reduce the volume of scrap iron and facilitate subsequent transportation, storage and reuse. A Chinese utility model patent (publication number: CN221017946U) discloses a scrap vehicle steel recycling device that realizes uninterrupted crushing and extrusion, improves the recycling efficiency of scrap iron and reduces recycling costs.

[0003] However, the above-mentioned device still has some shortcomings in use. Specifically, the existing punch press adopts a single-station design. After each processing is completed, when the cylinder pushes the squeezed scrap iron out of the compression chamber, the pushing mechanism needs to be reset to the initial position before the next scrap iron feeding and compression operation can be carried out. During this process, the equipment has a waiting time of "pushing out and resetting", which makes the processing process unable to be carried out continuously, the effective working time ratio is low, and the overall processing efficiency is difficult to improve. Therefore, a punch press for scrap iron processing is proposed to address the above situation. Utility Model Content

[0004] The purpose of this invention is to provide a punch press for scrap iron processing. Through the structural design of a support plate, a first hydraulic rod, and two U-shaped plates, when the scrap iron on one U-shaped plate is compressed and pushed out, the other U-shaped plate can simultaneously enter the processing station for the next round of punching operations without waiting for the first hydraulic rod to reset. This realizes a continuous process for scrap iron processing, improves work efficiency, and solves the problem that after the cylinder pushes the compressed scrap iron out of the compression chamber, the pushing mechanism needs to be reset to the initial position before the next scrap iron feeding and compression operation can be carried out, resulting in the inability to carry out the processing continuously, a low percentage of effective working time, and difficulty in improving the overall processing efficiency.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a punch press for scrap iron processing, including a compression chamber, an extrusion chamber at the top of the compression chamber, a feed pipe communicating with the extrusion chamber on one side of the compression chamber, and a punching mechanism fixed at the top of the compression chamber.

[0007] Both sides of the outer wall of the compression chamber are provided with discharge ports that connect to the extrusion chamber. Both sides of the compression chamber are fixed with support plates, and the top of the support plates is flush with the bottom surface of the discharge port.

[0008] Two U-shaped plates slide on the support plate, and load-bearing plates are detachably installed on the U-shaped plates. The two U-shaped plates are fixedly connected to each other. When one of the U-shaped plates passes through the discharge port and enters the extrusion chamber, the two side plates of the U-shaped plate are flush with the outer wall of the compression chamber.

[0009] Furthermore, the stamping mechanism includes a mounting bracket fixed to the top of the compression chamber. The top of the mounting bracket has a through hole, and a second hydraulic rod is fixed to the top of the mounting bracket. The telescopic end of the second hydraulic rod passes through the through hole and is fixed to a pressure plate. The pressure plate can move up and down in the extrusion chamber.

[0010] Furthermore, the support plate is in the shape of an inverted "L", and guide grooves are provided at both ends of the top of the support plate. Guide rods are fixed in the horizontal direction in the guide grooves.

[0011] Furthermore, a sliding frame is fixed to one side of the outer wall of the U-shaped plate. The sliding frame is in the shape of an inverted U-shape and has a through hole. The through hole slides with the guide rod. A first hydraulic rod is fixed to the outer wall of the compression chamber, and the telescopic end of the first hydraulic rod is fixed to one of the sliding frames.

[0012] Furthermore, the U-shaped plate has a slot, and both sides of the U-shaped plate have grooves, with a first screw hole connecting the slot in the groove.

[0013] Furthermore, a plug is fixed to the bottom of the load-bearing plate, and a second screw hole is provided on both sides of the plug. When the load-bearing plate is assembled on the U-shaped plate, the plug is inserted into the slot. A bolt is threaded into the first screw hole and the bolt extends into the second screw hole.

[0014] This utility model has the following beneficial effects:

[0015] This utility model, through the structural design of a support plate, a first hydraulic rod, and two U-shaped plates, allows the other U-shaped plate to simultaneously enter the processing station for the next round of stamping operations when the scrap iron on one U-shaped plate is extruded and pushed out, without waiting for the first hydraulic rod to reset. This eliminates the idle waiting time of the traditional single-station punch press's "push-reset" process, significantly increases the effective operating time of the equipment, realizes a continuous process for scrap iron processing, and improves work efficiency.

[0016] This utility model, through its structural design of slots, first screw holes, load-bearing plates, and inserts, allows operators to disassemble and replace load-bearing plates when long-term use causes wear and tear such as surface dents and deformation. This eliminates the need for large-scale disassembly of the main body of the equipment, shortens maintenance downtime, and reduces equipment maintenance costs.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a punch press for scrap iron processing, including a compression chamber 1, an extrusion chamber 10 is provided on the top of the compression chamber 1, a feed pipe 12 communicating with the extrusion chamber 10 is provided on one side of the compression chamber 1, and a punching mechanism is fixed on the top of the compression chamber 1.

[0026] The stamping mechanism includes a mounting frame 7 fixed to the top of the compression chamber 1. The top of the mounting frame 7 has a through hole. A second hydraulic rod 8 is fixed to the top of the mounting frame 7. The telescopic end of the second hydraulic rod 8 passes through the through hole and is fixed to a pressure plate 9. The pressure plate 9 can move up and down in the extrusion chamber 10.

[0027] The feed pipe 12 is fixed at an angle to one side of the compression chamber 1. It is made of seamless steel pipe and its diameter is designed according to the common scrap iron size to ensure that the scrap iron can slide into the extrusion chamber 10 by its own weight. The connection between the feed pipe 12 and the extrusion chamber 10 is rounded to avoid the scrap iron from getting stuck.

[0028] Both sides of the outer wall of the compression chamber 1 are provided with discharge ports 11 that connect to the extrusion chamber 10. Both sides of the compression chamber 1 are fixed with support plates 2, and the top of the support plates 2 is flush with the bottom surface of the discharge ports 11.

[0029] The support plate 2 is in the shape of an inverted "L". Both ends of the top of the support plate 2 are provided with guide grooves 20, and guide rods 21 are fixed in the horizontal direction of the guide grooves 20.

[0030] The discharge ports 11 on both sides of the compression chamber 1 are rectangular openings, with a width that matches the width of the U-shaped plate 3. The support plate 2 is made of cast steel. The vertical section of the inverted "L" shaped structure is fixed to the outer wall of the compression chamber 1 with bolts, and the horizontal section serves as the load-bearing foundation. The top is flush with the bottom surface of the discharge port 11 to ensure that the load-bearing plate 4 remains horizontal during the sliding process and to prevent scrap iron from falling off during transfer.

[0031] Two U-shaped plates 3 slide on the support plate 2. A load-bearing plate 4 is detachably installed on the U-shaped plate 3. The two U-shaped plates 3 are fixedly connected to each other. When one of the U-shaped plates 3 passes through the discharge port 11 and enters the extrusion chamber 10, the two side plates of the U-shaped plate 3 are flush with the outer wall of the compression chamber 1.

[0032] Two U-shaped plates 3 are fixed together by welding or high-strength bolts to form a dual-station structure that slides synchronously. When one of the U-shaped plates 3 enters the extrusion chamber 10, its two side plates are flush with the outer wall of the compression chamber 1 to ensure the integrity of the side wall of the extrusion chamber 10 and prevent scrap iron fragments from leaking out from the gaps during stamping.

[0033] The U-shaped plate 3 has a slot 30, and both sides of the U-shaped plate 3 have grooves 31. The grooves 31 have first screw holes 32 that connect to the slot 30. The bottom of the load-bearing plate 4 is fixed with a plug 40. Both sides of the plug 40 have second screw holes 41. When the load-bearing plate 4 is assembled on the U-shaped plate 3, the plug 40 is inserted into the slot 30. The first screw hole 32 is threaded with a bolt, which extends into the second screw hole 41. After the bolt is assembled, the bolt head is located in the groove 31.

[0034] A sliding frame 5 is fixed on one side of the outer wall of the U-shaped plate 3. The sliding frame 5 is in the shape of an inverted "U". A through hole is provided on the sliding frame 5. The through hole is slidably engaged with the guide rod 21. A first hydraulic rod 6 is fixed on the outer wall of the compression chamber 1. The telescopic end of the first hydraulic rod 6 is fixed on one of the sliding frames 5.

[0035] The guide groove 20 at the top of the support plate 2 is a rectangular groove, and the embedded guide rod 21 is made of chrome-plated round steel, which forms a clearance fit with the through hole of the sliding frame 5 to ensure that the sliding frame 5 slides horizontally without jamming. The sliding frame 5 is made of steel plate welded into an inverted "U" shape, and its two side walls fit against the vertical section of the support plate 2 to further improve sliding stability. The first hydraulic rod 6 is a double-acting hydraulic cylinder. The cylinder body is fixed to the reinforcing plate on the outer wall of the compression chamber 1 through a flange, and the telescopic end is rigidly connected to the middle of the sliding frame 5 to ensure uniform transmission of driving force and realize smooth switching between the two U-shaped plates 3.

[0036] In this embodiment, during use:

[0037] Initial state: The two U-shaped plates 3 are in the initial position. One of the U-shaped plates 3 carries the load-bearing plate 4 through the discharge port 11 into the extrusion chamber 10. The load-bearing plate 4 is located directly below the pressure plate 9. The other U-shaped plate 3 and the load-bearing plate 4 are on the support plate 2 outside the compression chamber 1. The sliding frame 5 is located at one end of the guide rod 21.

[0038] Feeding and pressing: The scrap iron to be processed slides into the extrusion chamber 10 through the feed pipe 12 and falls on the load-bearing plate 4 located in the chamber. The second hydraulic rod 8 is activated, and its telescopic end extends downward, driving the pressure plate 9 to move downward along the inner wall of the extrusion chamber 10 to extrude and form the scrap iron. After compression, the second hydraulic rod 8 drives the pressure plate 9 to return to the initial position.

[0039] Station switching: Activate the first hydraulic rod 6, and its telescopic end extends, pushing the sliding frame 5 to slide along the guide rod 21, causing the two U-shaped plates 3 to move synchronously. At this time, the load-bearing plate 4 located in the extrusion chamber moves out with the U-shaped plate 3 to the support plate 2 on the outside of the compression chamber 1. At the same time, the empty load-bearing plate 4 on the outside passes through the discharge port 11 and enters the extrusion chamber 10 with the other U-shaped plate 3 until the sliding frame 5 reaches the other end of the guide rod 21, completing the station switching.

[0040] Material handling and recycling: The operator removes the compressed scrap iron from the outer load-bearing plate 4 and adds new scrap iron to the load-bearing plate 4 that has just entered the extrusion chamber 10. The above stamping and station switching steps are repeated to achieve continuous scrap iron compression operation. When the surface of the load-bearing plate 4 becomes dented due to long-term use, the bolts in the groove 31 can be unscrewed, the old load-bearing plate 4 can be removed from the U-shaped plate 3, a new load-bearing plate 4 can be replaced, and the bolts can be tightened again to restore the stamping accuracy.
