Abstract
Description
Technical Field
[0001] This application relates to the technical field of drawer processing, and in particular to a stamping device for processing drawer bottoms. Background Technology
[0002] In the manufacturing of aluminum alloy or steel drawers, the quality of drawers, as widely used storage containers, is crucial. The drawer bottom, as a key component, directly affects the stability and load-bearing capacity of the overall drawer structure. Currently, the processing of drawer bottoms mainly employs a stamping process. The specific process is as follows: first, using stamping equipment, corresponding notches are stamped at the four corners of the sheet metal; then, using stamping equipment, the four edges of the sheet metal are bent at 90 degrees to form an upward-opening bucket-shaped structure, which is the basic shape of the drawer bottom.
[0003] A stamping device for bending drawer bottoms is disclosed. The device includes a base and a support arm fixed above the base. A vertically downward-pointing hydraulic cylinder is mounted on the upper end of the support arm. A stamping block is fixed to the end of the hydraulic rod of the hydraulic cylinder. A base plate is placed above the base, and a stamping groove is formed on the upper side of the base plate directly below the stamping block. During bending, the sheet metal with the notched stamp is placed on the base plate. The hydraulic cylinder is activated, causing the stamping block to move downwards. Under pressure, the middle portion of the sheet metal enters the stamping groove, and the edges are bent and abut against the inner wall of the stamping groove.
[0004] However, in mass production, the aforementioned stamping equipment is used in a high-frequency application scenario. However, in this environment, the hydraulic cylinder has difficulty tracking the control signal quickly and accurately. This may result in the impact force being difficult to control precisely when the stamping block moves down to stamp the sheet metal. For example, if the impact force is too large, it can easily damage the sheet metal. This not only wastes raw materials and increases production costs, but also affects production efficiency, leaving room for improvement. Utility Model Content
[0005] The purpose of this application is to provide a stamping equipment for processing drawer bottoms, which solves the problem that when the above-mentioned stamping equipment is used in high-frequency application scenarios, it is difficult to accurately control the impact force of the stamping block, which may cause waste of raw materials and increase production costs.
[0006] The stamping equipment for processing drawer bottoms provided in this application adopts the following technical solution:
[0007] A stamping device for processing drawer bottoms includes a processing table, a stamping table and a support arm located on the vertical side of the stamping table, a stamping plate located above the stamping table and a driving component for moving the stamping plate up and down on the support arm; a stamping block is fixed on the bottom side of the stamping plate, and a stamping groove is formed on the stamping table for the stamping block to be inserted as the stamping plate moves down; a plurality of guide rods are fixed on the upper side of the processing table in the vertical direction, and a guide through hole is formed on the stamping plate for the guide rods to pass through; a return spring in a compressed state is sleeved on the outer periphery of the guide rod, and the two ends of the return spring are fixedly connected to the sides of the processing table and the stamping plate that are close to each other.
[0008] By adopting the above technical solution, during the stamping process, the stamping plate drives the stamping block to move downwards and bend the sheet metal. The guide rod cooperates with the guide through hole, making the up-and-down sliding of the stamping plate more stable. At the same time, the return spring is in a compressed state. When the stamping block moves downwards and applies pressure to the sheet metal, the return spring is compressed, which plays a buffering role. In high-frequency application scenarios of mass production, this can effectively reduce the possibility of sheet metal damage due to excessive stamping force, avoid raw material waste, and reduce production costs.
[0009] Optionally, a guide sleeve fitted on the outer edge of the opening of the stamping groove is fixed on the stamping plate and sleeved on the outer periphery of the guide rod.
[0010] By adopting the above technical solution, the guide sleeve can fit more tightly with the guide rod, making the relative movement between the stamping plate and the guide rod smoother and more stable during the up and down movement, reducing friction and wear caused by shaking or deviation, and extending the service life of the equipment.
[0011] Optionally, a limiting block is fixed on the side of the stamping table away from the processing table, located at the four corners of the opening of the stamping groove. The limiting block is used to limit the sheet metal after the notch stamping is completed.
[0012] By adopting the above technical solution, during the bending process of the sheet metal, the four limiting blocks are respectively inserted into the notches at the four corners of the sheet metal, which can effectively prevent the sheet metal from shifting or shaking during stamping, ensuring that the sheet metal is accurately placed in the stamping position and ensuring that the relative position of the stamping block and the sheet metal is accurate.
[0013] Optionally, the stamping table has a receiving groove on the bottom side of the stamping groove, and a plurality of first springs are fixed on the bottom side of the receiving groove in the vertical direction; after the bending block is removed from the stamping groove, the upper end of the first spring can squeeze the bottom surface of the bent plate, so that the bottom surface of the plate moves up to a state that is flush with the upper side of the stamping table.
[0014] By adopting the above technical solution, when the bending block is removed from the stamping groove, the first spring, which is in a compressed state, returns to its original position and exerts an upward squeezing force on the bottom surface of the bent sheet, so that the bottom surface of the sheet moves up to be flush with the side surface of the stamping table, which facilitates subsequent material handling, inspection or further processing.
[0015] Optionally, a pressing plate is slidably disposed in the receiving trough, and the upper ends of several first springs are fixedly connected to the upper side of the pressing plate; the pressing plate is completely disposed in the receiving trough when the pressing block is inserted into the pressing trough.
[0016] By adopting the above technical solution, the presence of the extrusion plate allows the spring force of the first spring to act more evenly on the bottom surface of the sheet metal, avoiding uneven deformation of the sheet metal due to uneven spring distribution or localized stress, thus improving the flatness and quality stability of the sheet metal after bending. On the other hand, during stamping, the extrusion plate is completely within the receiving groove, preventing interference with the stamping process and ensuring that the stamping block can smoothly and accurately complete the bending operation of the sheet metal. After stamping, the first spring resets, pushing the extrusion plate upwards and smoothly lifting the bottom surface of the sheet metal to be flush with the side of the stamping table, facilitating subsequent operations and helping to improve overall production efficiency and product quality.
[0017] Optionally, the upper side of the processing table is fixed with an electric cylinder with a telescopic rod facing the stamping table in the horizontal direction. The end of the telescopic rod of the electric cylinder is fixed with a push plate whose bottom side is flush with the upper side of the stamping table. The push plate is used to push the bent sheet metal out from under the stamping block.
[0018] By adopting the above technical solution, after the drawer bottom plate has been bent, the push plate can smoothly and accurately push the bent sheet material out from under the stamping block under the drive of the electric cylinder. This design greatly simplifies the material handling process and avoids the inconvenience, inefficiency, and potential safety risks that may be caused by manual material handling.
[0019] Optionally, a downward-sloping guide slide is fixed on the vertical side of the processing table away from the electric cylinder. The highest point of the guide slide is flush with the upper side of the stamping table. A storage box is provided on one side of the processing table below the lowest point of the guide slide. The bent sheet can slide into the guide slide for unloading under the action of the push plate, and finally slide into the storage box.
[0020] By adopting the above technical solution, after the bent sheet metal is pushed out from under the stamping block by the push plate, it can automatically slide down the guide slide, realizing automatic unloading without manual intervention, which greatly improves production efficiency and reduces labor intensity. At the same time, the design of the guide slide being flush with the side of the stamping platform ensures that the sheet metal can slide smoothly into the guide slide, reducing the risk of jamming or falling during the descent.
[0021] Optionally, a plurality of support rods are fixedly provided on the lower side of the guide slide, and a connecting block is fixedly provided on the outer periphery of the support rods away from the processing table; a downwardly bent connecting rod is fixedly provided on the vertical side of the storage box near the guide slide, and the connecting block is provided with a connecting through hole for the lower end of the connecting rod to be inserted.
[0022] By adopting the above technical solution, a detachable connection between the guide slide and the storage box is achieved. When the storage box is full of boards and needs to be replaced, the guide slide and the storage box can be easily separated simply by pulling the connecting rod out of the connecting through hole. The operation is simple and quick, improving the flexibility and convenience of the production process.
[0023] In summary, this application includes the following beneficial technical effects:
[0024] During the stamping process, the stamping plate moves the stamping block downwards to bend the sheet metal. The guide rod engages with the guide through hole, making the up-and-down sliding of the stamping plate more stable. Simultaneously, the return spring is compressed; when the stamping block moves downwards and applies pressure to the sheet metal, the return spring is compressed, acting as a buffer. In high-frequency applications of mass production, this effectively reduces the possibility of sheet metal damage due to excessive stamping force, avoids raw material waste, and reduces production costs.

[0034] The present application will be further described in detail below with reference to all the accompanying drawings.
[0035] Example 1:
[0036] Reference Figure 1 and Figure 2 A stamping device for processing drawer bottoms includes a processing table 1, wherein a stamping table 2 is fixed on the processing table 1 and a support arm 11 located on the vertical side of the stamping table 2. A stamping assembly 3 is provided on the support arm 11, wherein the stamping assembly 3 includes a stamping plate 31 located above the stamping table 2 and a driving component 32 that drives the stamping plate 31 to move up and down. The driving component 32 is a conventional hydraulic cylinder fixed on the support arm 11, which will not be described in detail here.
[0037] A stamping block 33 is fixed on the bottom side of the stamping plate 31, and a stamping groove 21 located directly below the stamping block 33 is opened on the stamping table 2. When the plate is bent, the drive unit 32 is activated to drive the stamping plate 31 to move down, so that the stamping block 33, which moves down with the stamping plate 31, is inserted into the stamping groove 21. During this process, the middle part of the plate enters the stamping groove 21 under pressure, and the edge of the plate is bent and abuts against the inner wall of the stamping groove 21.
[0038] Reference Figure 3 Four guide rods 12 are fixedly installed on the upper side of the processing table 1 in the vertical direction. A guide through hole 311 is provided on the stamping plate 31 for the guide rods 12 to pass through. A return spring 13 in a compressed state is sleeved on the outer periphery of the guide rods 12. The two ends of the return spring 13 are fixedly connected to the sides of the processing table 1 and the stamping plate 31 that are close to each other.
[0039] A guide sleeve 312 is fixed on the outer edge of the opening of the stamping groove 21 on the stamping plate 31 and sleeved on the outer periphery of the guide rod 12, thereby improving the stability of the stamping plate 31 when it slides up and down; when the stamping block 33 is inserted into the stamping groove 21, the return spring 13 on the guide rod 12 is compressed, which plays a buffering role and reduces the possibility of the plate being damaged due to excessive stamping force.
[0040] Reference Figure 2 and Figure 3 On the side of the stamping table 2 away from the processing table 1, there are limiting blocks 22 located at the four corners of the opening of the stamping groove 21. When the sheet metal is bent, the four limiting blocks 22 are respectively inserted into the notches at the four corners of the sheet metal. That is, the limiting blocks 22 are used to limit the sheet metal after the notch stamping is completed.
[0041] The implementation principle of this application embodiment is as follows:
[0042] During operation, the sheet metal is placed on the stamping table 2. The drive unit 32 (hydraulic cylinder) is activated to move the stamping plate 31 downwards. The stamping block 33 on the stamping plate 31 then inserts downwards into the stamping groove 21 on the stamping table 2. The middle part of the sheet metal enters the stamping groove 21 under pressure, and the edge is bent and abuts against the inner wall of the stamping groove 21, thus achieving the bending process. At the same time, the return spring 13 on the guide rod 12 is compressed during the stamping process, which plays a buffering role and reduces the possibility of damaging the sheet metal due to excessive stamping force.

[0045] When the stamping block 33 is inserted into the stamping groove 21, the extrusion plate 5 is completely inside the receiving groove 23; after the bending block is removed from the stamping groove 21, the first spring 4 in the compressed state is reset, and at this time the extrusion plate 5 fixed at the upper end of the first spring 4 can press the bottom surface of the bent plate, so that the bottom surface of the plate moves up to the state of being flush with the upper side of the stamping table 2.
[0046] Reference Figure 4 and Figure 5The upper side of the processing table 1 is provided with a feeding assembly 6, which includes an electric cylinder 61 fixedly mounted on the upper side of the processing table 1 in a horizontal direction. The telescopic rod of the processing table 1 faces the stamping table 2. The end of the telescopic rod of the electric cylinder 61 is fixed with a push plate 62 whose bottom side is flush with the upper side of the stamping table 2.

[0047] Reference Figure 6 An inclined guide slide 63 is fixed on the vertical side of the processing table 1 away from the electric cylinder 61. The highest point of the guide slide 63 is flush with the upper side of the stamping table 2. A storage box 64 is provided on one side of the processing table 1 below the lowest point of the guide slide 63. The bent sheet can slide into the guide slide 63 for unloading under the action of the push plate 62, and finally slide into the storage box 64, thereby realizing the automatic unloading of the bent sheet.
[0048] Reference Figure 6 and Figure 7 Four support rods 631 are fixed on the lower side of the guide slide 63, and connecting blocks 632 are fixed on the outer periphery of the two support rods 631 away from the processing table 1; a downwardly bent connecting rod 641 is fixed on the vertical side of the storage box 64 near the guide slide 63, and a connecting block 632 is provided for the lower end of the connecting rod 641 to be inserted into the connecting through hole 6321; when the storage box 64 is installed, the two connecting rods 641 on the storage box 64 are inserted into the connecting through hole 6321 on the connecting block 632.
[0049] The implementation principle of this application embodiment is as follows:
[0050] After stamping, the first spring 4 resets and pushes the extrusion plate 5 upward, making the bottom surface of the bent sheet flush with the upper side of the stamping table 2, facilitating subsequent operations. Simultaneously, an electric cylinder 61 and a pusher plate 62 are installed on the processing table 1. The electric cylinder 61 drives the pusher plate 62 to push the bent sheet out from under the stamping block 33. An inclined guide slide 63 is provided on the side of the processing table 1, with its highest point flush with the upper side of the stamping table 2 and its lowest point below which a storage box 64 is placed.
