Description

Technical Field

[0001] This utility model relates to the field of metal product processing technology, specifically to a metal product stamping blanking recycling device. Background Technology

[0002] Metal products refer to finished or semi-finished products made from metal materials as the main raw materials through physical or chemical processing techniques, and have certain shapes, functions and uses. Their range covers from simple structural parts to high-precision parts, and they are widely used in industry, construction, transportation and daily life. Stamping is a cold working process that uses a press and mold to apply external force to metal or non-metal sheets, causing them to undergo plastic deformation or separation, thereby obtaining parts with the required shape, size and performance.

[0003] In the metal stamping process, the recycling efficiency of waste or scrap generated after stamping directly affects the cleanliness of the production environment, the utilization rate of raw materials, and the stability of continuous equipment operation. Traditional recycling methods usually use fixed hoppers to directly receive waste, relying on manual periodic cleaning or transfer through simple mechanical devices. Operators need to repeatedly interrupt the production process to clean up the accumulated material, reducing equipment utilization and the recycling efficiency of waste.

[0004] Therefore, a metal stamping blank recycling device is proposed to solve the above-mentioned technical problem of low recycling efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a metal product stamping blanking recycling device, which has the advantage of high recycling efficiency and solves the problem that operators need to repeatedly interrupt the production process to clean up accumulated materials, reducing equipment utilization and the efficiency of waste recycling.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a metal product stamping blanking recycling device, which is installed at the blanking hopper on the stamping machine body, including a storage bin connected to the blanking hopper, and an automatic unloading component is provided on the storage bin;

[0007] The automatic unloading assembly includes two symmetrically arranged rotating plates, which are hinged to the hopper via a hinge shaft. A baffle plate is provided on the rotating plate and is located at the discharge port of the hopper. A weight sensor is provided on the baffle plate. A drive unit connected to the baffle plate is provided on the hopper and is used to drive the baffle plate to rotate at the discharge port of the hopper.

[0008] Furthermore, a drive module is hinged to the outer side of the hopper via a hinge frame, a connecting shaft is hinged to the baffle plate via a hinge frame, and the piston rod of the drive module is hinged to the connecting shaft via the hinge shaft.

[0009] Furthermore, the two rotating blades are located on the front and rear sides of the hopper, respectively, and the rotating blades are fan-shaped.

[0010] Furthermore, a belt conveyor is provided below the baffle plate, and two baffles are symmetrically arranged on the belt conveyor. A recycling bin is also provided on the belt conveyor.

[0011] Furthermore, the longitudinal cross-sectional shape of the storage bin is an isosceles trapezoid, and the longitudinal cross-sectional shape of the baffle plate is arc-shaped.

[0012] Furthermore, the upper opening of the storage bin is larger than the lower opening, and the length of the baffle plate is greater than the length of the lower opening of the storage bin.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. This metal stamping blanking recycling device features a dynamic sealing system composed of symmetrically arranged fan-shaped rotating plates and arc-shaped baffles. When closed, the arc-shaped plate fits against the bottom of the storage bin to prevent material leakage. When opened, the rotating action pushes open the baffle. The weight sensor integrated on the baffle monitors the amount of material accumulation in real time. When the waste reaches a preset threshold, the drive unit is automatically activated to precisely control the rotation and opening of the baffle. Operators do not need to repeatedly interrupt the production process to clean up the accumulated material, thus improving recycling efficiency.

[0015] 2. This metal product stamping blanking recycling device has baffles on both sides of the belt conveyor to guide the flow, and the waste material falls directly into the end recycling box, forming a fully automated process, reducing manual handling links, and further improving recycling efficiency.

Detailed Implementation

[0022] 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.

[0023] Example 1:

[0024] Please see Figure 1-4 In this embodiment, a metal product stamping blanking recycling device is provided at the blanking hopper 200 on the stamping machine body 100, including a storage bin 300 connected to the blanking hopper 200, and an automatic unloading component 400 is provided on the storage bin 300.

[0025] The automatic unloading assembly 400 includes two symmetrically arranged rotating plates 401. The rotating plates 401 are hinged to the hopper 200 via a hinge shaft. A baffle plate 402 is provided on the rotating plates 401. The baffle plate 402 is located at the discharge port of the hopper 200. A weight sensor 403 is provided on the baffle plate 402. A drive unit connected to the baffle plate 402 is provided on the hopper 200. The drive unit is used to drive the baffle plate 402 to rotate at the discharge port of the hopper 200.

[0026] It should be noted that the stamping machine body 100 is a common piece of equipment in the prior art, and the usage method and working principle of the stamping machine body 100 are well known to those skilled in the art of metal product processing, and will not be described in detail in this application.

[0027] In application, stamping waste falls from the hopper 200 into the storage bin 300 and accumulates on the closed baffle plate 402. The weight sensor 403 monitors the waste load in real time. When the weight reaches a preset threshold, it sends a signal to the control unit. Upon receiving the signal, the drive unit starts and pushes the rotating plate 401, which is fixed to the baffle plate 402, to rotate around the hinge axis. The two fan-shaped rotating plates 401 rotate inward or outward synchronously, causing the baffle plate 402 to change from a horizontal closed state to an inclined open state. After the bottom of the storage bin 300 is fully open, the accumulated waste automatically slides down along the arc-shaped cross section of the baffle plate 402. After the weight sensor 403 detects that the load has returned to zero, the drive unit reverses its action, pulling the rotating plate 401 back to its original position. The baffle plate 402 rotates to a horizontal position, resealing the bottom of the storage bin 300, and waiting for the next round of material accumulation.

[0028] Example 2:

[0029] The basic content is the same as in Example 1, except that:

[0030] Please see Figure 3-5 In this embodiment, the outer side of the hopper 200 is hinged to the drive module 404 via a hinge frame, and the baffle plate 402 is hinged to the connecting shaft 405 via a hinge frame. The piston rod of the drive module 404 is hinged to the connecting shaft 405 via the hinge shaft.

[0031] It should be noted that the drive module 404 is connected to the control unit, and the control unit controls the piston rod of the drive module 404 to extend and retract at a constant speed to realize the rotation of the baffle plate 402; the control unit and its working principle are well known to those skilled in the art, and will not be described in this embodiment.

[0032] Two rotating blades 401 are located on the front and rear sides of the discharge hopper 200, respectively, and the rotating blades 401 are fan-shaped.

[0033] A belt conveyor 406 is installed below the baffle plate 402. Two baffles 407 are symmetrically arranged on the belt conveyor 406. A recycling bin 408 is installed on the belt conveyor 406.

[0034] It should be noted that belt conveyor 406 is a common piece of equipment in the prior art. The usage method and working principle of belt conveyor 406 are well known to those skilled in the art of metal product processing, and will not be elaborated further in this application.

[0035] The longitudinal section of the storage bin 300 is an isosceles trapezoid, and the longitudinal section of the baffle plate 402 is an arc.

[0036] The upper opening of the storage bin 300 is larger than the lower opening, and the length of the baffle plate 402 is greater than the length of the lower opening of the storage bin 300.

[0037] In application, when the weight sensor 403 detects that the waste material has reached the threshold, the piston rod of the drive module 404 extends linearly. The piston rod pushes the connecting shaft 405 through the hinge shaft, converting the linear motion into the rotational torque of the baffle plate 402. The fan-shaped rotating plate 401 rotates synchronously under the torque, causing the baffle plate 402 to change from a horizontal closed state to an inclined open state. After the bottom of the storage bin 300 is fully open, the accumulated waste material automatically slides down along the arc-shaped cross section of the baffle plate 402. After sliding down the baffle plate 402, the waste material falls directly into the belt conveyor 406. The baffles 407 on both sides constrain the movement trajectory of the waste material to prevent splashing. The belt conveyor 406 continuously transports the waste material to the recycling bin 408, realizing unmanned recycling. After the weight sensor 403 detects that the load has returned to zero, the drive unit reverses its action, pulling the rotating plate 401 back to its original position. The baffle plate 402 rotates to a horizontal position, resealing the bottom of the storage bin 300, waiting for the next round of accumulation.

[0038] In summary, the working principle of this metal stamping blanking recycling device is as follows:

[0039] When the weight sensor 403 detects that the waste material has reached the threshold, the piston rod of the drive module 404 extends linearly. The piston rod pushes the connecting shaft 405 through the hinge shaft, converting the linear motion into the rotational torque of the baffle plate 402. The fan-shaped rotating plate 401 rotates synchronously under the torque, causing the baffle plate 402 to change from a horizontal closed state to an inclined open state. After the bottom of the storage bin 300 is fully open, the accumulated waste material automatically slides down along the arc-shaped cross section of the baffle plate 402. After sliding down the baffle plate 402, the waste material falls directly into the belt conveyor 406. The baffles 407 on both sides constrain the movement trajectory of the waste material to prevent splashing. The belt conveyor 406 continuously transports the waste material to the recycling bin 408, realizing unmanned recycling. After the weight sensor 403 detects that the load has returned to zero, the drive unit reverses its action, pulling the rotating plate 401 back to its original position. The baffle plate 402 rotates to a horizontal position, resealing the bottom of the storage bin 300, waiting for the next round of accumulation.
