Description

Technical Field

[0001] The invention relates to the technical field of molds, and in particular to a high-strength photovoltaic profile mold with multiple cavities. Background Art

[0002] With the development of the photovoltaic industry, photovoltaic profiles are an important part of photovoltaic modules. Multi-cavity high-strength photovoltaic profiles have gradually become the preferred material for photovoltaic frame manufacturing due to their unique structure and excellent performance. Multi-cavity photovoltaic profiles are usually made of high-strength aluminum alloy materials, and are designed with multiple cavities inside. This structure not only reduces the weight of the profile, but also improves its torsion resistance and bearing capacity. The multi-cavity design is similar to an I-shaped structure, which can improve the reliability of photovoltaic modules under uneven load conditions and prevent the frame from bending or breaking. In the processing of photovoltaic profiles, they need to be stamped by molds;

[0003] In the stamping process of photovoltaic profiles, the workpiece to be processed is usually placed in the cavity of the lower mold, and then stamped and formed by the upper mold. In order to effectively prevent excessive deformation or damage to the profile caused by excessive stamping pressure, elastic columns are usually set around the lower mold. Its function is to apply reverse elastic force to the upper mold during the stamping process, which plays a role of buffering and protection;

[0004] During long-term use, the elasticity of the elastic column will gradually weaken or even be damaged. This phenomenon is mainly due to the frequent compression and recovery actions that the elastic column undergoes during repeated stamping, which causes fatigue damage inside the material. As time goes by, the elastic properties of the elastic column gradually decrease, and it cannot effectively provide sufficient buffering force, thereby reducing the service life of the mold and stamping accuracy, and increasing production costs and equipment maintenance frequency.

[0005] In order to solve the above problems, this application proposes a multi-cavity high-strength photovoltaic profile mold. Summary of the invention

[0006] The present invention proposes a multi-cavity high-strength photovoltaic profile mold, which solves the problem in the related art that the elasticity of the elastic column will gradually weaken during long-term use and it will be easy to be damaged.

[0007] The invention provides a multi-cavity high-strength photovoltaic profile mold, comprising a lower mold, an upper mold and a cooling oil storage assembly;

[0008] A base is installed at the bottom of the lower die. Cooling cylinders are installed around the base. The cooling oil storage assembly is respectively communicated with the cooling cylinders around the base. Cooling oil is arranged in the cooling cylinders. An elastic column assembly inserted into the cooling cylinders is installed on the cooling cylinders. An elastic push-pull assembly inserted into the elastic column assembly is installed on the elastic column assembly. The upper die is arranged above the lower die. Stamping rods are installed around the upper die, and the stamping rods around are respectively located above a plurality of elastic push-pull assemblies.

[0009] The cooling oil storage assembly includes a storage pressure-bearing assembly and a flow-dividing assembly. The cooling cylinders around the base are all communicated with the storage pressure-bearing assembly through the flow-dividing assembly.

[0010] As a further optimized solution of the present invention, the elastic column assembly includes a columnar elastic member and a top support shaft. The columnar elastic member is installed on the cooling cylinder and inserted into it, and the top support shaft is installed at the top of the columnar elastic member.

[0011] As a further optimized solution of the present invention, the columnar elastic member includes a column body, a second spring and a first piston. The column body slides through the top of the cooling cylinder and is inserted into it. The top support shaft is installed at the top of the column body. The second spring is sleeved on the column body, and both ends of the second spring are respectively connected with the cooling cylinder and the top support shaft. The first piston is fixed on the column body and fits with the top inside the cooling cylinder. A first air hole is opened at the top of the cooling cylinder.

[0012] As a further optimized solution of the present invention, the elastic push-pull assembly includes a rod-shaped elastic push-pull member and a bearing plate. A through oil passage is opened in the column body. The rod-shaped elastic push-pull member is installed on the top support shaft and inserted into the oil passage. The bearing plate is installed at the top of the rod-shaped elastic push-pull member, and a plurality of bearing plates are respectively located below a plurality of stamping rods.

[0013] As a further optimized solution of the present invention, the rod-shaped elastic push-pull member includes a push-pull rod, a third spring and a second piston. The push-pull rod slides through the top support shaft and is inserted into the oil passage. The bearing plate is installed at the top of the push-pull rod. The third spring is sleeved on the push-pull rod, and both ends of the third spring are respectively connected with the top support shaft and the bearing plate. The second piston is installed at the bottom of the push-pull rod and is located in the oil passage.

[0014] As a further optimized solution of the present invention, the storage pressure-bearing assembly includes a storage cylinder. Loading seats are installed at the bottoms of a plurality of cooling cylinders. The storage cylinder is installed between the base and the loading seats. A partition plate is installed in the storage cylinder through an elastic member. The partition plate divides the inside of the storage cylinder into an independent oil storage chamber and a cavity. The flow-dividing assembly is communicated with the oil storage chamber. A second air hole communicated with the cavity is opened at the top of the storage cylinder.

[0015] As a further optimized solution of the present invention, the elastic member includes a guide rod. Two vertically arranged guide rods are symmetrically installed in the storage cylinder. The partition disk is slidably sleeved on the two guide rods. A first spring is sleeved on the guide rod, and the two ends of the first spring are respectively connected to the partition disk and the top inside the storage cylinder.

[0016] As a further optimized solution of the present invention, a pressure sensor is installed at the top inside the cavity. An alarm is installed on the outer periphery of the storage cylinder. The pressure sensor is communicatively connected to the alarm. An impact block facing the pressure sensor is installed on the top of the partition disk.

[0017] As a further optimized solution of the present invention, the flow splitting assembly includes a diversion pipe. Two diversion pipes communicating with the oil storage chamber are symmetrically connected to the storage cylinder. Two flow splitting pipes are symmetrically connected to the ends of the diversion pipes away from the storage cylinder. The four flow splitting pipes are respectively connected to the cooling cylinders around the base.

[0018] As a further optimized solution of the present invention, a valve body is installed on the diversion pipe.

[0019] The above technical solution of the present invention has the following beneficial technical effects:

[0020] 1. In the present invention, the workpiece is placed in the lower die, and then the upper die approaches the lower die to stamp the workpiece inside it. When the upper die moves downward, the stamping rods around it move downward accordingly and stamp the elastic push-pull assembly on the cooling cylinders around the base. The elastic push-pull assembly can play the first layer of buffering role. After being stressed, the elastic push-pull assembly pushes the elastic column assembly downward to compress and enter the cooling cylinder. When the elastic column assembly moves downward, it performs the second layer of buffering and pushes the cooling oil in the cooling cylinder to enter the storage and pressure-bearing assembly along the flow splitting assembly. The storage and pressure-bearing assembly buffers the oil entering it to achieve the third layer of buffering. Through the design of the multi-layer buffering structure, the problems of reduced stamping accuracy and die damage caused by the weakened elasticity of the elastic column during the traditional stamping process are effectively solved. The multi-layer buffering mechanism also avoids excessive deformation or damage to the profile due to excessive or unstable punching force. At the same time, the multi-layer buffering structure effectively reduces the force impact on the elastic column assembly during the stamping process and reduces the generation of material fatigue damage, thereby prolonging the service life of the elastic column assembly;

[0021] 2. Since the upper die needs to stamp the workpieces placed in the lower die for a long time, the stamping rod on the upper die will exert pressure on the elastic push-pull component of the elastic column component, and the elastic column component will also be pressed down. The long-term downward movement will cause it to heat up and accelerate its wear. When the elastic column component moves downward in the cooling cylinder, the heat generated by the elastic column component can be absorbed by the cooling oil in the cooling cylinder, preventing the elastic column component from accelerating wear due to long-term high-temperature operation and extending its service life. When the upper die moves upward, the elastic column component immediately returns to its original position, and the elastic push-pull component also follows and returns to its original position. When the elastic push-pull component returns to its original position, it can suck the cooling oil in the cooling cylinder into the elastic column component, realizing double-layer cooling of the inside and outside of the elastic column component, further realizing double-layer cooling of the inside and outside of the elastic column component, enhancing its anti-wear performance, reducing the replacement times of the elastic column component, and reducing the material loss and maintenance cost in the production process;

[0022] 3. When the elastic column component moves downward in the cooling cylinder and pushes the cooling oil in the cooling cylinder into the oil storage chamber in the storage cylinder, under the action of the elastic member, the partition plate can be moved upward, and the impact block on the partition plate can stamp the pressure sensor in the cavity. The pressure sensor can monitor the elastic force buffered by the elastic column component. If it exceeds or is less than the threshold value, the alarm will sound through the alarm, reminding the operator to adjust the stamping force in time or repair the equipment. This real-time monitoring and early warning mechanism ensures that the stamping process is always carried out within a reasonable pressure range, avoids profile processing defects and equipment damage caused by abnormal elastic force, improves the safety and reliability of the production process, and also facilitates the operator to timely grasp the operating state of the equipment.

Detailed implementation manners

[0032] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0033] As Figure 1-8 shown, a high-strength photovoltaic profile mold with multiple cavities proposed by the present invention includes a lower die 1, an upper die 2 and a cooling oil storage assembly 4;

[0034] A base 101 is installed at the bottom of the lower die 1, cooling cylinders 3 are installed around the base 101, the cooling oil storage assembly 4 is respectively communicated with the cooling cylinders 3 around the base 101, cooling oil is provided in the cooling cylinders 3, an elastic column assembly 5 inserted therein is installed on the cooling cylinders 3, and an elastic push-pull assembly 6 inserted therein is installed on the elastic column assembly 5. The upper die 2 is arranged above the lower die 1, and stamping rods 21 are installed around the upper die 2, and the stamping rods 21 around are respectively located above a plurality of elastic push-pull assemblies 6;

[0035] The cooling oil storage assembly 4 includes a storage pressure-receiving assembly 41 and a flow splitting assembly 42, and the cooling cylinders 3 around the base 101 are all communicated with the storage pressure-receiving assembly 41 through the flow splitting assembly 42.

[0036] In actual use of the present invention, first place the photovoltaic profile workpiece to be processed in the lower die 1, and install the upper die 2 on the stamping equipment. After the stamping equipment is started, the upper die 2 approaches the lower die 1. At this time, the stamping rods 21 around the upper die 2 move downward with the upper die 2. During the downward movement of the stamping rods 21, they will contact and press down the elastic push-pull assembly 6. The storage and pressure-bearing assembly 41 in the cooling oil storage assembly 4 has previously stored cooling oil. The cooling oil is distributed into the cooling cylinders 3 around the base 101 through the shunt assembly 42. The cooling cylinders 3 are filled with cooling oil, providing a basis for subsequent cooling and buffering. After the elastic push-pull assembly 6 is stressed, it pushes the elastic column assembly 5 downward to compress and enter the cooling cylinders 3. When the elastic column assembly 5 moves downward, it performs a second layer of buffering, and pushes the cooling oil in the cooling cylinders 3 to enter the storage and pressure-bearing assembly 41 along the shunt assembly 42. The oil entering it is buffered by the storage and pressure-bearing assembly 41 to achieve a third layer of buffering. Through the design of the multi-layer buffering structure, the problems of reduced stamping accuracy and die damage caused by the weakened elasticity of the elastic column during the traditional stamping process are effectively solved.

[0037] As Figure 2 , Figure 3 and Figure 4 shown in this embodiment, the elastic column assembly 5 includes a columnar elastic member 51 and a top support shaft 52. The columnar elastic member 51 is installed on and inserted into the cooling cylinder 3, and the top support shaft 52 is installed at the top of the columnar elastic member 51.

[0038] When the elastic push-pull assembly 6 is subjected to the pressure of the stamping rod 21, it will push the top support shaft 52 downward. The top support shaft 52 is connected to the columnar elastic member 51, thereby driving the entire columnar elastic member 51 to move downward, playing a buffering role, reducing the impact force during stamping, protecting the lower die 1, the upper die 2 and the workpiece, and preventing the workpiece from deforming or being damaged due to excessive instantaneous pressure.

[0039] As Figure 4 shown, in this embodiment, the columnar elastic member 51 includes a column body 511, a second spring 512 and a first piston 513. The column body 511 slides through the top of the cooling cylinder 3 and is inserted therein. The top support shaft 52 is installed at the top of the column body 511. The second spring 512 is sleeved on the column body 511, and the two ends of the second spring 512 are respectively connected to the cooling cylinder 3 and the top support shaft 52. The first piston 513 is fixed on the column body 511 and fits with the top inside the cooling cylinder 3. The top of the cooling cylinder 3 is provided with a first air hole 31.

[0040] When the column 511 slides downward, the first piston 513 also moves downward in the cooling cylinder 3. Since the first piston 513 fits against the top of the cooling cylinder 3, it will push the cooling oil in the cooling cylinder 3 to flow. At the same time, the first air hole 31 plays a role in balancing the air pressure to prevent the normal flow of the cooling oil from being affected by the pressure change in the cooling cylinder 3. Under the action of pressure, the cooling oil flows along the diverter component 42 to the storage pressure component 41. In this process, the cooling oil absorbs the heat generated by the downward movement of the column elastic member 51, cools the column elastic member 51, reduces its wear caused by frictional heat, and extends the service life of the column elastic member 51.

[0041] like Figure 4 and Figure 5 As shown, in this embodiment, the elastic push-pull assembly 6 includes a rod-type elastic push-pull member 61 and a supporting plate 62. A through oil channel is opened in the column 511. The rod-type elastic push-pull member 61 is installed on the top support shaft 52 and inserted into the oil channel. The supporting plate 62 is installed at the top of the rod-type elastic push-pull member 61. Several supporting plates 62 are respectively located under several stamping rods 21.

[0042] The punching rod 21 presses down the supporting plate 62, and the supporting plate 62 drives the rod-type elastic push-pull member 61 to move downward. The push-pull rod 611 of the rod-type elastic push-pull member 61 slides in the top support shaft 52 and is inserted into the oil channel of the column 511. The third spring 612 is compressed to generate an upward elastic force. This is the first layer of buffering. When the push-pull rod 611 moves downward, the second piston 613 pushes the cooling oil in the oil channel, further enhancing the buffering effect. At the same time, it also promotes the circulation of the cooling oil in the elastic column assembly 5, thereby enhancing the cooling effect on the elastic column assembly 5.

[0043] like Figure 5 As shown, in this embodiment, the rod-type elastic push-pull member 61 includes a push-pull rod 611, a third spring 612 and a second piston 613. The push-pull rod 611 slides through the top support shaft 52 and is inserted into the oil channel. The supporting plate 62 is installed at the top of the push-pull rod 611. The third spring 612 is sleeved on the push-pull rod 611, and the two ends of the third spring 612 are respectively connected to the top support shaft 52 and the supporting plate 62. The second piston 613 is installed at the bottom end of the push-pull rod 611 and is located in the oil channel.

[0044] The push-pull rod 611 moves downward to compress the third spring 612 to provide a buffering force. The second piston 613 moves in the oil channel to push the cooling oil to flow. When the punching rod 21 moves upward, the third spring 612 restores its elastic deformation to push the push-pull rod 611 upward. The second piston 613 moves upward accordingly, and the cooling oil is sucked into the oil channel, realizing double-layer cooling of the inside and outside of the elastic column assembly 5, further reducing the temperature of the elastic column assembly 5, improving its wear resistance, and reducing the degradation of material properties caused by high temperature.

[0045] As Figure 2 , Figure 6 , Figure 7 shown, in this embodiment, the storage and pressure-receiving assembly 41 includes a storage cylinder 411. A loading seat 102 is installed at the bottom of several cooling cylinders 3. The storage cylinder 411 is installed between the base 101 and the loading seat 102. A partition plate 413 is installed in the storage cylinder 411 through an elastic member 412. The partition plate 413 divides the inside of the storage cylinder 411 into an independent oil storage chamber and a cavity. The flow dividing assembly 42 is communicated with the oil storage chamber. A second air hole 417 communicated with the cavity is opened at the top of the storage cylinder 411.

[0046] The cooling oil in the cooling cylinder 3 enters the oil storage chamber of the storage cylinder 411 through the flow dividing assembly 42. When the cooling oil enters, the pressure in the oil storage chamber increases, pushing the partition plate 413 to move upward. The partition plate 413 is connected to the storage cylinder 411 through the elastic member 412. The elastic member 412 plays a buffering role and further buffers the cooling oil entering the oil storage chamber, further reducing the impact force during the stamping process. At the same time, when the partition plate 413 moves upward, the impact block 414 will approach the pressure sensor 415 to prepare for pressure monitoring.

[0047] As Figure 7 and Figure 8 shown, in this embodiment, the elastic member 412 includes a guide rod 4121. Two vertically arranged guide rods 4121 are symmetrically installed in the storage cylinder 411. The partition plate 413 is slidably sleeved on the two guide rods 4121. A first spring 4122 is sleeved on the guide rod 4121, and both ends of the first spring 4122 are respectively connected to the partition plate 413 and the top inside the storage cylinder 411.

[0048] The guide rod 4121 provides a guiding function for the movement of the partition plate 413 to ensure its smooth up and down movement. During the up and down movement of the partition plate 413, the first spring 4122 provides a buffering force through its own elastic deformation. When the cooling oil enters the oil storage chamber and makes the partition plate 413 move upward, the first spring 4122 is compressed and absorbs part of the energy. When the stamping ends and the cooling oil flows back and the partition plate 413 moves downward, the first spring 4122 restores its deformation and assists the partition plate 413 to reset, ensuring the stable operation of the storage and pressure-receiving assembly 41.

[0049] As Figure 6 and Figure 8 shown, in this embodiment, a pressure sensor 415 is installed at the top inside the cavity. An alarm 416 is installed on the outer periphery of the storage cylinder 411. The pressure sensor 415 is communicatively connected with the alarm 416. An impact block 414 facing the pressure sensor 415 is installed on the top of the partition plate 413.

[0050] When the separation disk 413 moves upward, the impact block 414 contacts and presses the pressure sensor 415. The pressure sensor 415 converts the pressure signal into an electrical signal and compares it with a preset threshold. When the pressure exceeds or is less than the threshold, the pressure sensor 415 sends a signal to the alarm 416, and the alarm 416 issues an alarm. This mechanism can timely remind the operator that the buffer elasticity of the elastic column assembly 5 is abnormal. The operator can accordingly timely adjust the stamping force or repair the equipment, avoiding workpiece processing quality problems and equipment damage caused by abnormal elasticity, and improving the safety and reliability of production.

[0051] As Figure 6 shown, in this embodiment, the flow splitting assembly 42 includes a diversion pipe 421. Two diversion pipes 421 communicating with the oil storage chamber are symmetrically connected to the storage cylinder 411. Two flow splitting pipes 422 are symmetrically connected to the ends of the diversion pipes 421 away from the storage cylinder 411. The four flow splitting pipes 422 are respectively connected to the cooling cylinders 3 around the base 101.

[0052] The cooling oil in the cooling cylinder 3 flows into the diversion pipe 421 through the flow splitting pipe 422 and then enters the oil storage chamber of the storage cylinder 411. The design of the diversion pipe 421 and the flow splitting pipe 422 enables the cooling oil to be evenly distributed between each cooling cylinder 3 and the storage cylinder 411, ensuring the stability of the cooling oil circulation. At the same time, this flow splitting structure also helps to improve the cooling and buffering effects, enabling the entire mold to work more evenly during the stamping process.

[0053] As Figure 6 shown, in this embodiment, a valve body 423 is installed on the diversion pipe 421; it can be used to adjust the flow rate and pressure of the cooling oil. When it is necessary to adjust the circulation speed or buffering strength of the cooling oil, the operator can achieve this by controlling the valve body 423. When stamping photovoltaic profiles of different materials or specifications, the valve body 423 can be adjusted according to actual needs, so that the flow rate and pressure of the cooling oil adapt to different stamping working conditions, improving the adaptability of the mold and the stamping quality.

[0054] The specific working principle of the present invention is as follows:

[0055] When using this photovoltaic profile mold, first place the workpiece to be processed in the lower mold 1. The upper mold 2 moves downward under the drive of the stamping equipment, and the stamping rods 21 around the upper mold 2 move downward accordingly. The stamping rods 21 press the bearing plate 62 of the elastic push-pull assembly 6, and the bearing plate 62 drives the rod-shaped elastic push-pull member 61 downward. The push-pull rod 611 compresses the third spring 612, and the second piston 613 pushes the cooling oil in the oil passage to provide the first layer of buffering;

[0056] Meanwhile, the rod-type elastic push-pull member 61 pushes the top support shaft 52, causing the column-type elastic member 51 to move downward as a whole. The column body 511 compresses the second spring 512, and the first piston 513 pushes the cooling oil in the cooling cylinder 3 to flow through the flow splitting assembly 42 to the storage pressure-receiving assembly 41. This is the second layer of buffering. During the flow of the cooling oil, it absorbs the heat generated by the elastic column assembly 5 and cools it;

[0057] The cooling oil enters the oil storage chamber of the storage cylinder 411, causing the partition plate 413 to move upward, and the first spring 4122 of the elastic member 412 is compressed, achieving the third layer of buffering. The impact block 414 on the partition plate 413 approaches the pressure sensor 415, and the pressure sensor 415 monitors the pressure. If the pressure is abnormal, an alarm is given through the alarm 416;

[0058] When the stamping is completed, the upper die 2 moves upward, and the elastic push-pull assembly 6 and the elastic column assembly 5 return to their original positions under the action of their respective springs. During the return process, the elastic push-pull assembly 6 sucks the cooling oil into the elastic column assembly 5, realizing the internal and external double-layer cooling of the elastic column assembly 5. Throughout the process, the valve body 423 can adjust the flow rate and pressure of the cooling oil to adapt to different stamping requirements. Through the multi-layer buffering and cooling mechanism, the stamping accuracy is effectively improved, the service life of the lower die 1 and the upper die 2 is extended, and the safety and reliability of the production process are ensured.

[0059] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention.
