Description

Technical Field

[0001] The invention relates to the technical field of metal plate processing, in particular to a building curtain wall metal plate forming device. Background Art

[0002] Metal curtain wall is a kind of building exterior decorative structure composed of metal plates as panels and supporting structure system. It is lightweight, weather-resistant, highly plastic, easy to maintain and has good decorative effect. Common curtain wall metal plate materials include aluminum-plastic composite panels, aluminum veneers, honeycomb aluminum panels, fireproof panels, metal sandwich fireproof panels, titanium-zinc-plastic-aluminum composite panels, sandwich insulation aluminum panels, stainless steel panels, color-coated steel panels, enameled steel panels, etc. Stamping forming technology can be used to process building curtain wall metal plates. It is based on the principle that metal materials undergo plastic deformation after being subjected to force. The metal sheets of building curtain walls are processed through molds and stamping equipment, so that the sheets undergo plastic deformation without breaking to obtain the required shape and size.

[0003] During stamping, the metal plate is easily crushed due to the pressure on the metal plate or the stamping mold. The accumulation of these debris in the mold will cause the mold parts and the surface of the stamped parts to be crushed, such as embossing and convex spots on the metal plate, affecting the forming quality and appearance quality of the metal plate. This appearance quality problem is difficult to repair and increases the cost. At present, in order to clean up the debris problem, regular maintenance and cleaning of the mold is adopted. When cleaning, the debris in the mold can be cleaned by washing, wiping, blowing, etc. In order to avoid the impact of cleaning the mold on the stamping process, the cleaning process is usually carried out after a batch of metal plates are stamped. That is to say, during the stamping process, the debris is still in the mold, which is easy to affect the stamping quality of the next metal plate, and at the same time it will increase the labor intensity of manual cleaning.

[0004] In addition, during the stamping process, stamping oil usually needs to be applied to the mold and metal plate. Stamping oil has the functions of reducing friction, lubrication, cooling and rust prevention. At present, after stamping oil is applied to the metal plate in advance, during its transportation, the oil will be contaminated to the passing equipment, such as conveying equipment, which increases the workload of personnel in subsequent cleaning.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Refer to the instruction manual Figure 1-3 The present invention provides a building curtain wall metal plate forming equipment, including a shell 1 fixed on a frame, a punch 2 is arranged in the shell 1, and the punch 2 is driven to move by a hydraulic device. A lower die set 3 is arranged at the bottom of the punch 2 in the shell 1, and a metal plate raw material 5 is stamped and formed by the punch 2 and the lower die set 3.

[0048] Specifically, Figure 4-5 As shown, the lower mold assembly 3 includes a lower mold 31, a magnetic template 32 is fixed on the side of the lower mold 31 away from the opening end of the mold cavity, and the magnetic template 32 is semi-cylindrical, the lower mold 31 and the magnetic template 32 are connected to the same rotating rod 1 33 at one end, and the lower mold 31 and the magnetic template 32 are connected to the same rotating rod 2 34 at the other end, an outer frame 35 is provided on the outer side of the lower mold 31, and a fixing seat 36 is fixed to the bottom end of the outer frame 35, and the lower mold 31 and the magnetic template 32 are connected to the same rotating rod 33 at one end. The rotating rod 1 33 and the rotating rod 2 34 are rotatably connected to the outer frame 35, that is, the rotating rod 1 33 and the rotating rod 2 34 are fixedly connected to the lower mold 31 and the magnetic template 32, and the rotating rod 1 33 and the rotating rod 2 34 are rotatably connected to the outer frame 35 through bearings, and the outer frame 35 is designed to be a semicircular shape matching the magnetic template 32 to facilitate the rotation of the magnetic template 32, and a fixing seat 36 is fixed to the bottom end of the outer frame 35, and the rear side of the top end of the outer frame 35 is processed into an inclined surface.

[0049] Moreover, the punch 2 is transmission-connected with the rotating rod 2 34, and the transmission connection structure can adopt the existing structure to make the punch 2 move to drive the lower die set 3 to flip. This embodiment gives an example of a transmission connection structure: Figure 5-6 As shown, the transmission connection structure includes a rack and two gears, and the two gears are connected by a chain mechanism or a belt mechanism, one of the gears is meshed with the rack, and the other gear is fixed on the rotating rod 2 34, and an outer cover is fixed on the side of the outer frame 35 close to the transmission connection structure, and the two gears are arranged in the outer cover, and the rack can pass through the outer cover.

[0050] Moreover, a limiting block 37 is fixed on the front side of the top end of the lower mold 31 , and a limiting groove 38 matched with the limiting block 37 is opened on the top of the outer frame 35 .

[0051] When the punch 2 moves downward, the rack is driven to move downward, and the rack drives the gear to rotate and drive the second rotating rod 34 to rotate, thereby driving the lower mold 31 and the magnetic template 32 to flip backward 180 degrees until the limit block 37 is limited by the limit groove 38, that is, Figure 4-5 The status changes to Figure 6 State, at this time, the lower die 31 is flipped to the die cavity vertically upward, and the magnetic template 32 is accommodated in the outer frame 35. When the punch 2 continues to move downward, the rack and the gear are separated, so that the lower die 31 maintains the current state. At this time, the metal plate raw material 5 is fed to the die cavity of the lower die 31, and then the punch 2 stamps a section of the metal plate raw material 5 between the punch 2 and the lower die 31.

[0052] Then, if Figure 1 , Figure 2 and Figure 7 As shown, a driving component 4 for driving the metal plate raw material 5 to feed is provided on one side of the punch 2, and the driving component 4 includes an outer frame 41 and a plurality of rollers 42 arranged on one side of the outer frame 41. The rollers can be driven to rotate by a driving device such as a motor, and the plurality of rollers 42 can be connected by a belt mechanism for synchronous rotation; a transverse plate 12 is also fixedly provided on the side of the punch 2 close to the driving component 4, and the transverse plate 12 is arranged on the top of the outer frame 41, and the transverse plate 12 is connected to the outer frame 41 by a telescopic rod 11. When the punch 2 moves downward, it drives the outer frame 41 to move downward so that the rollers 42 are in contact with the metal plate raw material 5 to drive the metal plate raw material 5 to move and feed.

[0053] like Figure 1-2 As shown, a bracket 14 is also provided at the bottom of the metal plate raw material 5. The four corners of the bottom of the bracket 14 are supported by two supporting legs 15 and two sets of telescopic supporting legs 13 respectively. The bracket 14 is rotatably connected to the two supporting legs 15. Fig.12 As shown, the telescopic supporting leg 13 includes an outer rod 131, an inner rod 132 and a spring 133. The inner rod 132 is arranged inside the outer rod 131 and extends out of the top of the outer rod 131. The spring 133 is used to connect the bottom end of the inner rod 132 with the bottom end inside the outer rod 131. The bottom end of the outer rod 131 is rotatably connected to the top of the frame, and the top of the inner rod 132 is rotatably connected to the bottom end of the bracket 14.

[0054] In order to cut the shaped metal sheet immediately from the metal sheet raw material 5 after stamping, Figure 1-3 As shown, the lower die set 3 is provided with a cutting assembly 6 at one end close to the driving assembly 4. Specifically, Figure 9-10As shown, the cutting assembly 6 includes a support plate 61 and a rotating plate 62, and the support plate 61 and the rotating plate 62 are rotatably connected via a rotating shaft 63 (it should be noted that the rotating shaft 63 is connected to the support plate 61 and the rotating plate 62 via a one-way bearing so that the support plate 61 and the rotating plate 62 can only rotate in one direction), and the rotating shaft 63 is sleeved with a torsion spring 64 for connecting the support plate 61 and the rotating plate 62, the end of the support plate 61 away from the rotating plate 62 is sleeved on the rotating rod 33, and the end of the rotating plate 62 away from the support plate 61 is fixed with a cutting device, and the cutting device includes a tool housing 9 and a tool 10 arranged in the tool housing 9, and the tool 10 is driven to rotate by a driving device such as a motor for cutting.

[0055] like Fig.11 FIG. 1 is a schematic diagram of the working process of the cutting assembly 6 from the left side. At the beginning, the cutting device faces forward. During stamping, the cutting assembly 6 rotates backward along with the rotating rod 33 on the lower die 31 until it contacts the metal plate raw material 5, so that the rotating plate 62 and the supporting plate 61 rotate (from Fig.11 The rotating plate 62 can rotate clockwise relative to the supporting plate 61 in the left direction), and the torsion spring 64 is twisted at the same time, until the cutting assembly 6 passes over the bottom of the metal sheet raw material 5, and the cutting assembly 6 is restored under the elastic force of the torsion spring 64, that is, the cutting assembly 6 will not hinder the forming work of the metal sheet raw material 5 when it rotates backward; after the stamping is completed, the cutting assembly 6 rotates with the lower die 31, and the knife 10 of the cutting device cuts the metal sheet raw material 5 (from the metal sheet raw material 5) during the rotation process. Fig.11 The one-way bearing limits the counterclockwise rotation of the rotating plate 62 relative to the supporting plate 61 in the left direction), so that the rightmost formed metal plate of the metal plate raw material 5 is cut off, and then the formed metal plate can be taken out manually or by a robot.

[0056] The support plate 61 is also slidably connected to the rotating rod 33, and a locking bolt for fixing the support plate 61 and the rotating rod 33 is threadedly connected to the support plate 61. The cutting assembly 6 slides on the rotating rod 33 and is then locked to adjust the position of the cutting assembly 6, thereby cutting different positions of the metal plate raw material 5.

[0057] The working principle is:

[0058] Before stamping, the punch 2 is at the highest position, the cavity of the lower die 31 faces downward, the magnetic template 32 is located at the top of the lower die 31, and the cutting device is located in the front. The end of the bracket 14 close to the housing 1 is tilted, and then a whole piece of unprocessed metal plate raw material 5 is placed on the bracket 14;

[0059] During stamping, the punch 2 moves downward to drive the lower die 31 and the magnetic template 32 to flip backward. At the same time, the punch 2 drives the driving assembly 4 to move downward through the cross plate 12 and the telescopic rod 11 so that the roller 42 contacts the metal sheet raw material 5. Then the telescopic rod 11 contracts until the telescopic rod 11 contracts to the shortest position, and the bracket 14 remains tilted. Then the punch 2 continues to move downward to drive the driving assembly 4 to press down the raised end of the bracket 14 so that the bracket 14 rotates clockwise to a horizontal state. In this process, the elastic force generated by the compression of the spring 133 in the telescopic support leg 13 makes the roller 42 close to the metal sheet raw material 5. The rotating roller 42 transports the metal sheet raw material 5 to the right. At the same time, the cutting device passes over the bottom of the metal sheet raw material 5 and flips to the rear until the section of the metal sheet raw material 5 that needs to be stamped is transported to the top of the lower die 31. Then the punch 2 stamps a section of the metal sheet raw material 5 between the punch 2 and the lower die 31 (the formed part is called a formed metal sheet). Figure 8 As shown;

[0060] After the stamping is completed, the punch 2 moves upward and resets to drive the horizontal plate 12, the telescopic rod 11, the driving assembly 4 and the bracket 14 to reset. The reset bracket 14 drives the formed section of the metal plate raw material 5 to be lifted up and taken out from the lower die 31. Then the lower die 31 and the magnetic template 32 rotate until the limit block 37 enters the limit groove 38. At this time, the cavity of the lower die 31 faces downward to vibrate and clean out the debris generated by the stamping in the lower die 31. When in use, a drawer for collecting the debris can be placed at the bottom end of the fixed seat 36 to realize immediate cleaning of the debris in the lower die 31 after each stamping.

[0061] At the same time, during the rotation of the magnetic template 32, the magnetic template 32 can rotate at the bottom of the formed metal plate. On the one hand, it is used to lift the formed metal plate to facilitate unloading. On the other hand, the magnetic template 32 contacts the formed metal plate to absorb the debris on the formed metal plate. In the next round of stamping, the magnetic template 32 flips again. At this time, the magnetic template 32 rotates along the rear side of the top of the outer frame 35 to scrape off the debris absorbed on it. At the same time, the scraped debris falls along the inclined surface of the rear side of the top of the outer frame 35. A collection box for collecting the debris can be placed below the inclined surface of the outer frame 35, which effectively reduces the labor intensity of subsequent personnel cleaning the debris on the formed metal plate.

[0062] At the same time, during the rotation of the lower mold 31, the cutting device is driven to rotate to the front to cut off the formed metal plate and the unformed part on the metal plate raw material 5. Then the formed metal plate can be taken out manually or by a robot, eliminating the step of cutting the metal plate raw material 5 before stamping, thereby improving the overall processing efficiency.

[0063] like Figure 7As shown, an upper oiling assembly 7 is provided on the driving assembly 4, and the upper oiling assembly 7 includes an oil box 71, oil absorbing cotton 72 and an oil delivery pipe 73. The oil box 71 is fixed to the other side of the inner part of the outer frame 41, the oil absorbing cotton 72 is fixed to the bottom of the oil box 71, and the bottom end of the oil absorbing cotton 72 extends out of the bottom of the outer frame 41. The stamping oil in the oil box 71 soaks the oil absorbing cotton 72 through the oil holes at the bottom thereof, and the oil delivery pipe 73 is fixed to the rear end of the oil box 71, and the oil delivery pipe 73 passes through the rear end of the outer frame 41 for connecting to an external oil pipe. A valve or a pipe cover can be installed on the oil delivery pipe 73 to store the stamping oil in the oil box 71.

[0064] At the same time, if Figure 9-10 As shown, a lower oiling assembly 8 is provided on the cutting assembly 6, and the lower oiling assembly 8 includes a hollow oil containing plate 81, oil absorbing cotton 82 and an oil filling pipe 83. The hollow oil containing plate 81 is fixed to the outside of the tool housing 9, the oil absorbing cotton 82 is fixed to the side of the hollow oil containing plate 81 away from the tool housing 9, and the oil filling pipe 83 is fixed to the outside of the hollow oil containing plate 81 for connecting an external oil pipe. A valve or a pipe cover can be installed on the oil filling pipe 83 for storing stamping oil in the hollow oil containing plate 81, and the stamping oil in the hollow oil containing plate 81 soaks the oil absorbing cotton 82 through the oil holes thereon.

[0065] The working principle is:

[0066] During the process of the rotating roller 42 contacting and feeding the metal plate raw material 5, the oil-absorbing cotton 72 is always in close contact with the top surface of the metal plate raw material 5, the oil-absorbing cotton 72 can clean the top surface of the metal plate raw material 5 passing by, and then apply the stamping oil on it to the top surface of the metal plate raw material 5. When the cutting component 6 passes over the bottom of the metal plate raw material 5, the oil-absorbing cotton 82 on the cutting component 6 is always in contact with the bottom end surface of the metal plate raw material 5 passing by, the oil-absorbing cotton 82 can clean the bottom end surface of the metal plate raw material 5 passing by, and then apply the stamping oil on it to the bottom end surface of the metal plate raw material 5, thereby realizing dust removal and stamping oil application of the metal plate raw material 5. The oiling operation of the present invention not only improves the forming quality of the metal plate, but also is fast and convenient, avoiding the problem of oil contamination to other equipment and increasing the workload of personnel.

[0067] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
