Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a waste discharge structure for computer chassis stamping dies. Background Technology

[0002] As a fundamental component of modern electronic devices, computer cases are typically produced on a large scale and with high efficiency through stamping processes. During the stamping process, the stamping press drives the upper and lower dies to rapidly form the metal sheet. Inevitably, waste is generated during this process. This waste will remain in or around the lower die and must be removed in a timely manner to prevent it from affecting the accuracy of the next stamping or even damaging the die.

[0003] In current production practices, the methods for handling these stamping wastes are relatively primitive. A common method is to rely on manual cleaning at regular intervals. Operators need to use tools to remove the waste from the mold area during the intervals of the stamping cycle. This method not only greatly reduces the overall automation level and production efficiency of the production line, but also brings serious safety hazards because workers need to operate close to the dangerous mold area.

[0004] To improve automation, some production lines attempt to install simple conveyor belts under the molds, allowing scrap to fall onto the conveyor belt due to gravity and be transported away. However, this passive approach cannot handle scrap stuck in the mold cavity or attached to the mold surface. More importantly, stamping scrap often carries contaminants such as stamping oil, which fall onto the conveyor belt surface along with the scrap and gradually accumulate. A contaminated conveyor belt can cause slippage and poor conveying, leading to scrap accumulation and blockage. In severe cases, it requires frequent shutdowns for manual cleaning and maintenance, which also disrupts production continuity and does not fundamentally solve the reliability problem of automated operation.

[0005] Therefore, this utility model proposes a waste discharge structure for computer chassis stamping molds to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of low automation of waste cleaning, low efficiency due to reliance on manual labor, and easy contamination of the conveying device by waste in the existing waste discharge structure of computer chassis stamping mold, this utility model aims to provide a waste discharge structure of computer chassis stamping mold with improved structure that can effectively solve the above problems.

[0007] This utility model provides a waste discharge structure for computer chassis stamping molds, including: a lower mold, and a conveying mechanism disposed below the lower mold, the conveying mechanism including a conveyor belt; as well as a hydraulic rod, a protruding plate and a cleaning mechanism.

[0008] The hydraulic rod is located on one side of the lower mold, and the protruding plate is connected to the telescopic end of the hydraulic rod, which is used to push the waste material in the mold onto the conveyor belt.

[0009] Furthermore, the cleaning mechanisms are arranged in combination near the surface of the conveyor belt to remove dirt from the surface of the conveyor belt.

[0010] Preferably, the conveying mechanism further includes a vertical plate, at least two rotating rods, and a drive assembly. The vertical plate supports the rotating rods, the conveyor belt is sleeved around the outer periphery of the rotating rods, and the drive assembly is used to drive the rotating rods to rotate.

[0011] Preferably, the drive assembly includes a motor and a connecting rod, wherein the motor drives the rotating rod via the connecting rod.

[0012] Preferably, the cleaning mechanism includes a horizontal plate serving as a mounting base, a sweeping brush, a scraper, and a power assembly, wherein the power assembly is used to drive the sweeping brush and the scraper to reciprocate along the width direction of the conveyor belt.

[0013] Preferably, the cleaning mechanism further includes a slide bar, on which the cleaning brush and scraper are slidably coupled.

[0014] Preferably, the power assembly includes a bidirectional threaded rod, and the cleaning brush and the scraper are respectively threadedly connected to two sections of threads with different directions of rotation on the bidirectional threaded rod.

[0015] Preferably, the power assembly further includes a second motor, a worm gear, and a worm wheel. The second motor drives the worm gear to rotate, the worm gear meshes with the worm wheel, and the worm wheel drives the bidirectional threaded rod to rotate. Preferably, the discharge structure is integrated into a stamping press, and the stamping press includes an upper die that works in conjunction with the lower die.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problems of low efficiency and safety hazards in the prior art, which are that stamping waste often needs to be manually cleaned, and the waste is automatically transported away by a conveyor belt, by setting a hydraulic rod to drive the protruding plate. It achieves the technical effects of automatic waste discharge, improved production efficiency and reduced manual labor intensity.

[0018] 2. This utility model integrates a cleaning mechanism that can automatically reciprocate on the conveying mechanism. The cleaning mechanism cleans the surface of the conveyor belt with a cleaning brush and a scraper, which solves the problems of slippage, poor conveying or secondary pollution that may occur due to waste pollution after long-term use of the conveyor belt. It achieves the technical effect of keeping the conveying mechanism clean and ensuring the long-term stable and reliable operation of the equipment.

[0019] 3. This utility model, by using a motor-driven worm gear mechanism, and the worm gear driving the bidirectional threaded rod to rotate, cleverly utilizes the different directions of the threads of the bidirectional threaded rod to drive the cleaning brush and scraper to perform reciprocating linear motion, solving the problem of needing complex control or multiple power sources to achieve reciprocating cleaning action, and achieving the technical effect of compact cleaning mechanism structure, simple and reliable transmission chain, and convenient control.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example:

[0028] Please refer to Figures 1 to 4 This utility model provides a waste discharge structure for computer chassis stamping dies, which aims to solve the problems of low automation in the cleaning of die waste in existing computer chassis stamping production and unstable operation caused by easy contamination of conveying equipment.

[0029] like Figure 1 and Figure 2 As shown, the waste discharge structure of the computer chassis stamping die is integrated on the stamping machine 1. The stamping machine 1 includes an upper die 4 and a lower die 5 that work together. The discharge structure mainly includes a conveying mechanism 2 located below the lower die 5 and a cleaning mechanism 3 located on the conveying mechanism 2. The upper die 4 and the lower die 5 of the stamping machine 1 work together to complete the stamping operation and generate waste. The conveying mechanism 2 is used to receive and transport the waste discharged from the lower die 5. The cleaning mechanism 3 is used to clean the conveying mechanism 2 to ensure its long-term stable operation.

[0030] To achieve proactive and automated discharge and transfer of waste material within the lower mold 5, please refer to the following: Figures 1 to 4 The following is a detailed description of the conveying mechanism 2 and its cooperating waste pushing structure:

[0031] The conveying mechanism 2 includes a vertical plate 201 as a supporting frame, at least two rotating rods 202 rotatably connected between the vertical plate 201, and a conveyor belt 203 sleeved on the outer periphery of the rotating rods 202. The conveying mechanism 2 also includes a drive assembly 206, which includes a motor 2061 and a connecting rod 2062 connected to its output end. The motor 2061 drives one of the rotating rods 202 to rotate via the connecting rod 2062, thereby driving the conveyor belt 203 to circulate.

[0032] To eject waste material from the lower mold 5, the structure also includes a hydraulic rod 204 located on one side of the lower mold 5 and a protruding plate 205 fixedly connected to the telescopic end of the hydraulic rod 204. After the upper mold 4 of the stamping machine 1 is lifted and disengaged from the lower mold 5, the hydraulic rod 204 extends and retracts, driving the protruding plate 205 to reciprocate within the lower mold 5, thereby pushing the stamping waste material within the lower mold 5 onto the conveyor belt 203 below, where it is then transported away. This structure, which combines pushing and conveying, ensures that waste material can be removed promptly and reliably. Based on the above embodiment, to further ensure the long-term clean operation of the conveying mechanism 2, the cleaning mechanism 3 of this utility model preferably adopts the following specific structure:

[0033] As a preferred embodiment, please refer to Figure 3 and Figure 4 The cleaning mechanism 3 includes a horizontal plate 301, which is fixed on the vertical plate 201 or an independent bracket as the mounting base of the cleaning mechanism 3. The cleaning mechanism 3 also includes a cleaning brush 302, a scraper 303, a slide bar 304, and a power assembly 305 for driving. The cleaning brush 302 and the scraper 303 are slidably engaged on the slide bar 304, which provides guidance for the reciprocating motion of the cleaning brush 302 and the scraper 303 along the width direction of the conveyor belt 203.

[0034] More specifically, the power assembly 305 includes a second motor 3052, a worm gear 3053 connected to the output end of the second motor 3052, a worm wheel 3054 meshing with the worm gear 3053, and a bidirectional threaded rod 3051. The slide rod 304 is arranged parallel to the bidirectional threaded rod 3051. The worm wheel 3054 is coaxially fixedly connected to the bidirectional threaded rod 3051. The second motor 3052 drives the bidirectional threaded rod 3051 to rotate through the transmission of the worm gear 3053 and the worm wheel 3054. The two sections of the bidirectional threaded rod 3051 have different thread directions. The cleaning brush plate 302 and the scraper plate 303 are respectively threaded to these two sections of threads with different directions, thereby realizing the linear reciprocating motion of the two components in opposite directions driven by a single rotational power.

[0035] Working principle: When using the conveyor mechanism 2, firstly, by turning on the motor 2061 in the drive assembly 206 on the outside of the right vertical plate 201, the rotating rod 202 outside the connecting rod 2062 at the output end rotates. The press 1 pulls up the upper mold 4 and separates it from the lower mold 5. Since the two rotating rods 202 connected to the front of the press 1 are driven by the conveyor belt 203, the hydraulic rod 204 is then turned on to drive the front protrusion plate 205 to extend and retract. During the extension and retraction process, the protrusion plate 205 pushes the waste material in the lower mold 5 of the press 1 out. Finally, the waste material falls onto the conveyor belt 203 for removal and disposal, realizing automatic material discharge.

[0036] The cleaning mechanism 3 is used to remove dirt from the surface of the conveyor belt 203. When using the cleaning mechanism 3, the motor 3052 in the power assembly 305 is started and drives the worm gear 3053 to rotate. When the worm gear 3053 rotates, it meshes with the worm wheel 3054 on the outer side of the bidirectional threaded rod 3051 on the middle of the side adjacent to the cross plate 301, thereby driving the bidirectional threaded rod 3051 to rotate. During the rotation of the bidirectional threaded rod 3051, it drives the cleaning brushes 302 and scrapers 303 on both sides of the two different threads to clean and scrape the dirt on the conveyor belt 203. The slide bar 304 plays a guiding role, thereby achieving the cleaning of the conveyor belt 203.
