Description

Technical Field

[0001] This utility model relates to the field of punching device technology, specifically a punching device for mechanical equipment processing. Background Technology

[0002] In the field of modern mechanical equipment processing, punching devices are an extremely important processing equipment, widely used in many industries such as metal processing, machinery manufacturing, automotive parts production, and building decoration material processing. With the continuous development of industrial production and the increasing requirements for product precision and efficiency, traditional manual punching methods can no longer meet the needs of large-scale, high-quality production. As a result, various mechanical punching devices have emerged.

[0003] Hydraulic and pneumatic technologies have also been gradually introduced into punching devices. Hydraulic punching devices utilize the pressure transmission principle of hydraulic oil in a closed system. High-pressure oil is provided by a hydraulic pump to drive a hydraulic cylinder to drive the punch for punching. It has advantages such as high output and the ability to punch thicker materials.

[0004] However, current punching devices lack effective and stable components to make the punching process more stable, and the efficiency needs to be improved. They cannot perform cutting at the same time as punching, cannot adapt well to workpieces of different widths, and their applicability needs to be improved. They also cannot handle the debris generated during punching well. In view of this, we propose a punching device for mechanical equipment processing. Utility Model Content

[0005] The purpose of this utility model is to provide a punching device for machining mechanical equipment, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A punching device for machining equipment includes a frame, a horizontal plate fixedly installed on the inner side of the frame, a base plate fixedly installed on the top of the horizontal plate, a column fixedly installed on the top of the base plate, a top plate fixedly installed on the top of the column, and a punching assembly disposed on the inner side of the frame. The punching assembly includes:

[0008] A hydraulic cylinder is fixedly installed on the top of the top plate. A movable frame is fixedly installed on the piston end of the bottom of the hydraulic cylinder. A drive bearing is fixedly installed on the inner side of the movable frame. The drive bearing is slidably installed on the outer side of the column. An upper mold is fixedly installed at the bottom of the movable frame. A punch head is fixedly installed at the bottom of the upper mold. A driven bearing is fixedly installed on the inner side of the movable frame. A slide rod is slidably installed inside the driven bearing. A long strip block is fixedly installed at the bottom of the slide rod. A through hole is opened on the long strip block. The punch head passes through the through hole.

[0009] A fixing block is fixedly installed on the top of the base plate and a lower die. The lower die has a through discharge hole located directly below the punch head. The workpiece body is attached to the top of the fixing block and the lower die. There are two sets of fixing blocks. One set of fixing blocks has a stop block fixedly installed on the top of the fixing block, and the other set of fixing blocks has a pad plate fixedly installed on the top of the fixing block. The side wall of the workpiece body is attached to the outer wall of the stop block.

[0010] The tool holder is fixedly installed at the bottom of the movable frame. The tool head has an installation groove. The tool head is fixedly installed at the bottom of the tool holder by a fixing member in the installation groove. The pad is located directly below the tool head. The limiting plate has an auxiliary groove. The limiting plate is fixedly installed on the fixing block by a fixing member in the auxiliary groove.

[0011] Preferably, multiple sets of columns are provided, thereby making the movement of the mobile frame more stable.

[0012] Preferably, the active bearing, upper die, stamping head, driven bearing, slide rod, through hole, lower die, and discharge hole are provided in two sets, and the two sets of active bearing, upper die, stamping head, driven bearing, slide rod, through hole, lower die, and discharge hole are symmetrically arranged at the left and right ends of the moving frame with the vertical center line of the moving frame as the axis of symmetry, thereby improving production efficiency.

[0013] Preferably, two sets of limiting plates are provided, and the two sets of limiting plates are located at the front and rear ends of the workpiece body, so that the limiting plates are placed more stably.

[0014] Preferably, an auxiliary component is provided on the outside of the mobile frame. The auxiliary component includes a hopper, and the hopper is fixedly installed at the bottom of the horizontal plate. The hopper is located below the discharge hole.

[0015] Preferably, a suction pump is fixedly installed on the top of the horizontal plate, a bent pipe is fixedly installed at the air inlet of the suction pump, a conical cover is fixedly installed on the outside of the bent pipe, and a sloping cover is fixedly installed on the outside of the conical cover. The sloping cover is located inside the side wall of the hopper, and a filter plate is snapped onto the sloping side wall of the sloping cover. The filter plate faces the discharge hole, and the inner diameter of the filter hole opened on the filter plate is smaller than the outer diameter of the punching head, so as to better collect the waste material after punching and avoid the waste material getting stuck inside the discharge hole.

[0016] Compared with the prior art, the present invention provides a punching device for machining equipment, which has the following beneficial effects:

[0017] 1. This punching device for machining processes, in order to improve punching efficiency, is equipped with a punching assembly. A hydraulic cylinder and a drive bearing enable the moving frame to drive the upper die and punch head to move up and down. A long block allows the sliding rod to slide within the driven bearing. The punch head passes through the through hole, thus enabling punching. A fixed block, lower die, discharge hole, and stop block are used to place the workpiece body. A mounting groove and a limiting plate further secure the workpiece body. It can also accommodate workpieces of different widths, improving applicability. When the moving frame moves, it causes the tool holder and cutter head to move synchronously. An auxiliary groove allows the cutter head's mounting position on the tool holder to be changed. This, combined with a backing plate, allows for cutting of the workpiece body, further improving punching efficiency.

[0018] 2. The punching device for this mechanical equipment is equipped with auxiliary components to better handle the debris generated during punching. Under normal circumstances, the debris generated by the punch head pressing the workpiece body falls into the hopper through the discharge hole and is collected. After the punch head returns to its upward position to end the punching operation, the suction pump is started, which works with the bent pipe, conical cover, and inclined cover to draw air into the discharge hole. The filter plate prevents the debris from being sucked into the inclined cover, thus avoiding the debris from getting stuck inside the discharge hole and enabling better collection of the debris after punching.

[0027] 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.

[0028] Please see Figure 1 - Figure 7 This utility model provides a technical solution:

[0029] A punching device for machining machinery includes a frame 1, a horizontal plate 2 fixedly installed on the inner side of the frame 1, a base plate 3 fixedly installed on the top of the horizontal plate 2, and a column 4 fixedly installed on the top of the base plate 3. In addition, four sets of columns 4 are provided to make the movement of the movable frame 62 more stable. A top plate 5 is fixedly installed on the top of the column 4.

[0030] In one embodiment of this utility model, a punching assembly 6 is provided on the inner side of the frame 1. The punching assembly 6 includes a hydraulic cylinder 61. The hydraulic cylinder 61 is fixedly installed on the top of the top plate 5. A movable frame 62 is fixedly installed on the piston end of the bottom of the hydraulic cylinder 61. An active bearing 63 is fixedly installed on the inner side of the movable frame 62. The active bearing 63 is slidably installed on the outer side of the column 4. An external main controller controls the start of the hydraulic cylinder 61, and the movable frame 62 at the bottom of the hydraulic cylinder 61 begins to move. Since the active bearing 63 on the inner side of the movable frame 62 can slide on the outer side of the column 4, the movable frame 62 can move up and down smoothly. An upper die 64 is fixedly installed on the bottom of the movable frame 62. A punching head 65 is fixedly installed on the bottom end of the upper die 64. A driven bearing 66 is fixedly installed on the inner side of the movable frame 62. A sliding rod 67 is slidably installed inside the 66, which drives the upper die 64 and the stamping head 65 fixed at its bottom to move up and down synchronously. When the moving frame 62 drives the stamping head 65 to move downward, a long strip block 68 is fixedly installed at the bottom of the sliding rod 67. A through hole 69 is opened on the long strip block 68, and the stamping head 65 passes through the through hole 69. A fixing block 610 and a lower die 611 are fixedly installed at the top of the base plate 3. A through discharge hole 612 is opened on the lower die 611, which is located directly below the stamping head 65. In addition, there are two sets of driving bearing 63, upper die 64, stamping head 65, driven bearing 66, sliding rod 67, through hole 69, lower die 611 and discharge hole 612, and the two sets of driving bearing 63, upper die 64, stamping head 65 and driven bearing 66 are provided. The slide bar 67, through hole 69, lower die 611, and discharge hole 612 are symmetrically arranged at both ends of the moving frame 62 with the vertical center line as the axis of symmetry, thereby improving production efficiency. The workpiece body 613 is attached to the top of the fixed block 610 and the lower die 611. The long strip block 68 will first contact the top of the workpiece body 613. At this time, the slide bar 67 will slide in the driven bearing 66, while the punch head 65 continues to pass down through the through hole 69 on the long strip block 68. Finally, the punch head 65 passes through the discharge hole 612 located directly below the lower die 611, thereby completing the punching operation on the workpiece body 613, which helps to improve production efficiency. There are two sets of fixed blocks 610. One set of fixed blocks 610 has a stop block 614 fixedly installed on the top. A set of fixing blocks 610 has a pad 620 fixedly installed on its top. The side wall of the workpiece body 613 is attached to the outer wall of the stop block 614. The bottom of the moving frame 62 has a tool holder 615 fixedly installed. The tool head 616 has a mounting groove 617. The tool head 616 is fixedly installed to the bottom of the tool holder 615 through the fixing parts in the mounting groove 617. The pad 620 is located directly below the tool head 616. The workpiece body 613 is placed on the placement area formed by the fixing blocks 610 and the lower mold 611. The stop block 614 is attached to the side wall of the workpiece body 613, which plays a preliminary limiting role. The limiting plate 618 has an auxiliary groove 619. The limiting plate 618 is fixedly installed on the fixing block 610 through the fixing parts in the auxiliary groove 619. In addition, there are two sets of limiting plates 618.Furthermore, two sets of limiting plates 618 are located at the front and rear ends of the workpiece body 613, making the limiting plates 618 more stable. It is worth noting that the fixing components are bolts, and threaded holes are provided at corresponding positions. Since bolts and threaded holes are existing equipment, they will not be described in detail here. Simultaneously, the two sets of limiting plates 618 further fix the workpiece body 613. The limiting plates 618 are fixed to the fixing block 610 by fixing components (bolts) in the auxiliary groove 619, thus accommodating workpiece bodies 613 of different widths and improving applicability. When the moving frame 62 moves, the tool holder 615 at its bottom and the cutter head 616 fixed to the bottom of the tool holder 615 by fixing components (bolts) in the mounting groove 617 will move synchronously. The auxiliary groove 619 can be used to change the installation position of the cutter head 616 on the tool holder 615, allowing it to work in conjunction with the pad 620 located directly below the cutter head 616 to perform cutting operations on the workpiece body 613, further enhancing the function of the device and improving punching efficiency.

[0031] In one embodiment of this utility model, an auxiliary component 7 is provided on the outside of the movable frame 62. The auxiliary component 7 includes a feeding hopper 71. The feeding hopper 71 is fixedly installed at the bottom of the horizontal plate 2. A collecting device is provided at the bottom end of the feeding hopper 71. The feeding hopper 71 is located below the discharge hole 612. During the punching process, the debris generated by the punch head 65 pressing the workpiece body 613 will fall into the feeding hopper 71 located below it through the discharge hole 612 on the lower die 611. The collecting device is connected to the bottom end of the feeding hopper 71 to achieve preliminary collection of debris. In addition, a suction pump 72 is fixedly installed at the top of the horizontal plate 2. A bent pipe 73 is fixedly installed at the air inlet end of the suction pump 72. A conical cover 74 is fixedly installed on the outside of the bent pipe 73. An inclined cover 75 is fixedly installed on the outside of the conical cover 74. The inclined cover 75 is located inside the side wall of the feeding hopper 71. After the punch head 65 returns to its original position and completes one punching operation, the external controller starts the suction pump 72. The bent pipe 73 fixed at the air inlet of the suction pump 72 begins to draw in air. The conical cover 74 fixed outside the bent pipe 73 and the inclined cover 75 fixed outside the conical cover 74 guide the airflow direction, causing the airflow to be drawn towards the discharge hole 612. The inclined side wall of the inclined cover 75 is fitted with a filter plate 76, which faces the discharge hole 612. The inner diameter of the filter holes on the filter plate 76 is smaller than the outer diameter of the punch head 65. The inclined side wall of the inclined cover 75 is fitted with a filter plate 76, which faces the discharge hole 612 and whose filter hole inner diameter is smaller than the outer diameter of the punch head 65. This effectively prevents debris from being sucked into the inclined cover 75, thereby avoiding debris from getting stuck in the discharge hole 612 and thus better completing the collection of debris after punching.

[0032] All electrical components mentioned in this application are electrically connected to an external main controller and 220V AC mains power. The main controller is a conventional known device that controls the hydraulic cylinder 61 and the suction pump 72. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.

[0033] Working principle: Preparation stage: First, the workpiece body 613 is placed on the placement area consisting of the fixing block 610 and the lower mold 611. The stop block 614 fits against the side wall of the workpiece body 613, which plays a preliminary limiting role. At the same time, the workpiece body 613 is further fixed by two sets of limiting plates 618. The limiting plates 618 are fixed to the fixing block 610 by means of the fasteners (bolts) in the auxiliary groove 619, so as to adapt to workpiece bodies 613 of different widths and improve applicability.

[0034] Punching action trigger: The external main controller controls the start of hydraulic cylinder 61, and the moving frame 62 at the bottom of hydraulic cylinder 61 starts to move. Since the active bearing 63 on the inner side of the moving frame 62 can slide on the outer side of the column 4, the moving frame 62 can move up and down smoothly, thereby driving the upper die 64 and the punch head 65 fixed at its bottom to move up and down synchronously. When the moving frame 62 drives the punch head 65 to move downward, the long block 68 will first contact the top of the workpiece body 613. At this time, the slide rod 67 will slide in the driven bearing 66, and the punch head 65 continues to pass down through the through hole 69 on the long block 68. Finally, the punch head 65 passes through the discharge hole 612 located directly below the lower die 611, thereby completing the punching operation on the workpiece body 613, which helps to improve production efficiency.

[0035] Cutting operation: When the moving frame 62 moves, the tool holder 615 at its bottom and the cutter head 616 fixed to the bottom of the tool holder 615 by the fixing parts (bolts) in the mounting groove 617 will move synchronously. With the help of the auxiliary groove 619, the installation position of the cutter head 616 on the tool holder 615 can be changed so that it can cooperate with the pad plate 620 located directly below the cutter head 616 to cut the workpiece body 613, which further enhances the function of the device and improves the punching efficiency.

[0036] During normal punching, the debris generated by the punch head 65 pressing the workpiece body 613 will fall into the hopper 71 located below it through the discharge hole 612 on the lower die 611. The bottom of the hopper 71 is connected to a collection device to achieve the initial collection of debris.

[0037] Enhanced debris removal after stamping: After the stamping head 65 returns to its original position and completes one stamping operation, the external controller starts the suction pump 72. The bend 73 fixed at the air inlet of the suction pump 72 begins to draw in air. The conical cover 74 fixed outside the bend 73 and the inclined cover 75 fixed outside the conical cover 74 guide the airflow direction, causing the airflow to be drawn towards the discharge hole 612. The inclined side wall of the inclined cover 75 is fitted with a filter plate 76. The filter plate 76 faces the discharge hole 612 and its filter hole inner diameter is smaller than the outer diameter of the stamping head 65. This effectively prevents debris from being sucked into the inclined cover 75, thereby avoiding debris from getting stuck in the discharge hole 612 and thus better completing the debris collection work after punching.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
