Description
Technical Field
[0001] This application relates to the field of stamping die technology, and particularly to a die for processing roof chimney covers. Background Art
[0002] A roof chimney cover is a cover installed at the chimney outlet position on the roof. The main uses of the roof chimney cover include beautifying the environment, preventing birds or other small animals from entering the chimney interior, enhancing the aesthetics of the chimney, and preventing wind backflow in specific situations. The roof chimney cover not only has practical functions such as preventing animals from entering and preventing wind backflow, but also has a decorative effect of beautifying the environment and enhancing the aesthetics of the building.
[0003] The structure of the roof chimney cover is relatively simple, but during the manufacturing process, the problem of adapting to the chimney outlet needs to be considered. Therefore, it is often necessary to deform it by stamping to fit the chimney outlet. However, due to the imperfect traditional manufacturing process, it is impossible to ensure that the chimney cover can be formed in one step while achieving shape adaptation during the manufacturing process, resulting in a slow manufacturing process of the chimney cover. Utility Model Content
[0004] In order to improve the structure of the existing chimney cover manufacturing equipment, so that the chimney cover that meets the usage requirements can be formed in one step and avoid the cumbersome process of multiple processing, this application provides a die for processing roof chimney covers.
[0005] A die for processing roof chimney covers provided by this application adopts the following technical solutions:
[0006] A die for processing roof chimney covers includes a base, a plate member, and a stamping plate spaced above the base for stamping the plate member into shape. A limiting groove for slidingly mating with the stamping plate and for placing the plate member is provided on the base. First mounting holes and second mounting holes are respectively formed on the base and the stamping plate. A pressing block is slidably mounted in the first mounting hole, and the pressing block is slidably mated with the second mounting hole. A first air cylinder for pushing the pressing block up into the second mounting hole is provided at the bottom of the pressing block. A first punching hole is formed through the middle of the side of the pressing block close to the stamping plate. A punching block slidably mated with the first punching hole is slidably mounted in the second mounting hole. A second air cylinder for pushing the punching block into the first punching hole is provided at the top of the punching block. A limiting mechanism for restricting the sliding of the plate member is provided on the base.
[0007] By adopting the above technical solution, when processing the plate member of the roof, the plate member is limited by the limiting mechanism on the base, and then the second cylinder on the top pressing plate is first used to drive the punching block to punch the plate member, so that the holes for smoke to escape in the middle of the plate member are punched and formed. Then, the first cylinder is used to drive the top pressing block to punch the plate member in the direction opposite to the movement of the punching block, so that the middle part of the plate member bulges. It is possible to integrally form the plate member while ensuring the manufacturing accuracy, which simplifies the processing steps and improves the production efficiency of the plate member, and improves the overall economic practicality of the mold.
[0008] Optionally, the limiting mechanism includes two limiting blocks symmetrically and slidably arranged on the base along the direction extending perpendicular to the limiting groove, a bidirectional screw fixed on the side of the base away from the punching plate, and a motor drivingly connected to the middle of the bidirectional screw. The motor is installed on the side of the base away from the punching plate. One end of each of the two limiting blocks close to the base penetrates through the base and is respectively threadedly connected to both ends of the bidirectional screw. The vertical distance between the sides of the limiting block and the sliding groove close to each other is equal to the width of the plate member.
[0009] By adopting the above technical solution, when the plate member is in the limiting groove, the motor drives the bidirectional screw to rotate, so that the two limiting blocks approach each other, thereby realizing the complete limitation of the plate member in the horizontal direction by the mold, avoiding errors in processing caused by the movement of the plate member during processing, improving the qualified rate of the finished product, and when the plate member is processed, the motor drives the two limiting blocks to move away from each other, so that the plate member can be quickly removed from the base, further improving the production efficiency of the mold.
[0010] Optionally, the height of each of the two limiting blocks along the punching direction is less than or equal to the depth of the limiting groove.
[0011] By adopting the above technical solution, it is possible to prevent the limiting block from being squeezed during the punching of the plate member by the punching plate, causing damage to the limiting block and its connection structure, and protecting the structural integrity of the mold parts.
[0012] Optionally, the sides of the two limiting blocks close to each other are in close contact with each other.
[0013] By adopting the above technical solution, the stability of the limiting block for limiting the plate member can be improved. At the same time, since the two limiting blocks are in close contact with each other, the structure of the limiting mechanism is more stable during the processing, and the impact resistance of the limiting mechanism is improved.
[0014] Optionally, columns are provided at opposite ends of the base. A sliding sleeve is slidably sleeved on the end of the column away from the base. A spring is connected between the bottom of the sliding sleeve and the bottom of the column. The two ends of the punching plate are symmetrically provided with abutting blocks corresponding to the two sliding sleeves respectively.
[0015] By adopting the above technical solution, when the stamping plate stamps the plate on the base, it can prevent the impact force of the stamping plate on the base from being too large, provide buffering for the equipment, and improve the stability and safety of the overall operation of the mold.
[0016] Optionally, the height of the limiting groove along the stamping direction is equal to the thickness of the plate.
[0017] By adopting the above technical solution, during the processing, the stamping plate can be completely in close contact with the upper end surface of the plate and form an extrusion effect, so as to reduce the processing error of the middle part of the plate when it is pressed and formed by the pressing block, and ensure that the overall size of the plate will not change due to the middle part being lifted.
[0018] Optionally, a feeding mechanism for feeding the plate into the limiting groove is arranged at one end of the base. The feeding mechanism includes a bottom plate arranged at one end of the base far from the limiting block, two support plates symmetrically installed on the bottom plate, and a rotating roller rotatably connected to the two support plates. The distance between the rotating roller and the bottom plate is equal to the thickness of the plate, and the surface of the rotating roller is rough.
[0019] By adopting the above technical solution, the plate is clamped between the bottom plate and the rotating roller. When the rotating roller rotates, since the surface of the rotating roller is rough and the distance between the rotating roller and the bottom plate is equal to the thickness of the plate, the plate will move, realizing the automatic placement of the plate into the limiting groove, improving the overall automation degree of the mold, and at the same time, the transportation of the plate by the feeding mechanism can also improve the processing efficiency of the plate.
[0020] Optionally, two guiding wheels are rotatably embedded on both sides of the limiting groove on the base along the width direction. Both of the two guiding wheels are arranged on the side of the limiting groove far from the limiting block. Card slots are opened on the side parts of the two guiding wheels, and rubber friction pads are laid in the card slots. The distance between the bottoms of the two card slots is equal to the length of the plate along the direction perpendicular to the extension direction of the limiting groove.
[0021] By adopting the above technical solution, the success rate of the plate entering the limiting groove can be improved, and the phenomenon that when the plate is pushed into the limiting groove by the feeding mechanism, the plate has a displacement along the direction perpendicular to the moving direction and requires manual correction of the position of the plate can be avoided.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. By the combined action of the first cylinder and the second cylinder respectively arranged on the base and the stamping plate, the plate is integrally processed and formed by the mold, improving the production efficiency of the chimney cover and simplifying the production process of the chimney cover;
[0024] 2. By setting a limiting mechanism for the plate on the base, this application can improve the qualified rate of the processed chimney cover products. At the same time, it also facilitates the quick removal of the processed plate from the mold, saving processing time.
[0025] 3. By setting a pushing mechanism, the plate enters the limiting groove under the combined action of the bottom plate and the rotating roller, improving the automation degree of the mold and saving labor costs. Brief Description of the Drawings

Detailed Description of the Embodiment
[0035] The following is combined with the attachedFigure 1-8 Further details of the present application will be described below.
[0036] An embodiment of the present application discloses a mold for processing a roof chimney cover.
[0037] Referring to Figure 1 、 Figure 2 and Figure 4 A mold for processing a roof chimney cover specifically includes a base 1, a plate member 2 to be processed into a chimney cover, and a stamping plate 3 disposed above the base 1 at intervals. The stamping plate 3 can move up and down to perform a stamping operation on the plate member 2 placed on the base 1. A limiting groove 11 for preventing the movement of the plate member 2 is formed in the base 1. One side of the limiting groove 11 communicates with the edge of the base 1. The plate member 2 can slide inside the limiting groove 11 and slide out of the limiting groove 11 through the opening on one side of the limiting groove 11, improving the flexibility of the conveying of the plate member 2. First mounting holes 12 and second mounting holes 31 are respectively formed along the axis on the base 1 and the stamping plate 3. The shapes and sizes of the first mounting holes 12 and the second mounting holes 31 are the same and are matched with the dimensions of the protruding structure formed after stamping the plate member 2.
[0038] Among them, the depth of the limiting groove 11 is equal to the thickness of the plate member 2, so that the stamping plate 3 can abut against the plate member 2 and limit the movement of the plate member 2.
[0039] Referring to Figure 2 and Figure 3 Further, a pressing block 13 for forming a protruding structure on the plate member 2 is slidably mounted in the first mounting hole 12. The pressing block 13 is slidably matched with the second mounting hole 31. When the stamping plate 3 presses the plate member 2 located on the base 1, the pressing block 13 will lift the middle part of the plate member 2 and enter the second mounting hole 31, and a first air cylinder 14 for driving the pressing block 13 is fixedly installed at one end of the pressing block 13 away from the stamping plate 3.
[0040] Referring to Figure 3 Furthermore, a first punching hole 131 is formed through the pressing block 13 along the axis. A punching block 32 slidably matched with the first punching hole 131 is slidably disposed in the second mounting hole 31. The punching block 32 is driven by a second air cylinder 33 embedded in the position of the second mounting hole 31 in the stamping plate 3 to perform a punching operation on the middle part of the plate member 2, so that the plate member 2 can be integrally formed.
[0041] Referring to Figure 2 and Figure 5, a limiting mechanism 4 for restricting the sliding of the plate member 2 in the limiting groove 11 is provided on the base 1. The limiting mechanism 4 includes two limiting blocks 41 symmetrically arranged and slidably disposed on the base 1 along a direction perpendicular to the extending direction of the limiting groove 11, and a bidirectional screw 42 rotatably installed on the side of the base 1 away from the stamping plate 3. The bottom ends of the two limiting blocks 41 both penetrate the base 1 and are respectively threadedly sleeved on the opposite threaded ends of the bidirectional screw 42, so that when the bidirectional screw 42 rotates, the two limiting blocks 41 can approach or move away from each other under the drive of the bidirectional screw 42. The middle part of the bidirectional screw 42 is drivingly connected to a motor 43 for driving the bidirectional screw 42 to rotate, and the motor 43 is fixedly installed on the base 1.
[0042] Referring to Figure 5 and Figure 6 Further, the two limiting blocks 41 can be made to be in close contact through the drive of the double thread to improve the structural stability of the limiting mechanism 4, and the vertical distance between the side of the limiting block 41 close to the limiting groove 11 is equal to the width of the plate member 2, that is, when the sides of the two limiting blocks 41 in contact with each other abut, the plate member 2 located in the limiting groove 11 can be completely limited in the horizontal direction. At the same time, the height of the limiting block 41 along the stamping direction is less than or equal to the depth of the limiting groove 11, so that when the stamping plate 3 stamps the plate member 2, it will not collide with the limiting block 41 and cause damage to the limiting block 41.
[0043] In this application, since the connection between the motor 43 and the bidirectional screw 42 is mainly a driving connection, any driving structure that meets the installation and use conditions of this application can be used as the technical support of this application, and the connection structure at this position is not explicitly shown in the drawings.
[0044] Referring to Figure 6 and Figure 7 , columns 15 are fixedly provided at opposite ends of the base 1, and a sliding sleeve 151 is slidably sleeved on the end of the column 15 away from the base 1. A spring 152 is fixedly connected between the sliding sleeve 151 and the bottom of the column 15. Two abutting blocks 34 corresponding to the two sliding sleeves 151 are symmetrically and fixedly connected to the stamping plate 3. When the stamping plate 3 stamps the plate member 2 in the limiting groove 11 on the base 1, the abutting block 34 abuts against the sliding sleeve 151, serving the purpose of buffering the stamping plate 3 and protecting the base 1.
[0045] Referring to Figure 4 and Figure 6, at one end of the base 1 away from the limit groove 11, there is a feeding mechanism 5 for pushing the plate member 2 into the limit groove 11. It includes a bottom plate 51 arranged at one end of the base 1 at intervals, two support plates 52 symmetrically installed on the bottom plate 51, and a rotating roller 53 with both ends rotatably connected to the two support plates 52 and having a rough surface. The distance between the rotating roller 53 and the bottom plate 51 is equal to the thickness of the bottom plate 51, so that when it rotates, it can send the plate member 2 into the limit groove 11 on the base 1.
[0046] Referring to Figure 6 and Figure 8 , further, there are two guiding rotating wheels 16 arranged on both sides of the limit groove 11 on the base 1, and both of the two guiding rotating wheels 16 are arranged on the side of the base 1 away from the limit block 41 of the limit groove 11. Both of the two guiding rotating wheels 16 are provided with clamping grooves 161 along the axis, and a rubber friction pad 162 is laid in the sliding groove. The distance between the bottoms of the clamping grooves 161 on the two guiding rotating wheels 16 is equal to the width of the plate member 2, so that when the plate member 2 is pushed into the limit groove 11 by the feeding mechanism 5, its two ends can abut against the two guiding rotating wheels 16 to perform lateral limiting on it.
[0047] The implementation principle of a mold for processing a roof chimney cover in an embodiment of the present application is as follows:
[0048] The plate member 2 is placed between the rotating roller 53 and the bottom plate 51 and is pushed onto the base 1 as the rotating roller 53 rotates. At this time, the two guiding rotating wheels 16 on the base 1 jointly clamp both sides of the plate member 2, and the clamping grooves 161 on them play an effect of clamping and limiting on the plate member 2. Then the plate member 2 is sent into the limit groove 11, and the motor 43 drives the bidirectional screw 42 to rotate, so that the two limit blocks 41 act together to form horizontal limiting on the plate member 2.
[0049] Then, the stamping plate 3 presses the plate member 2 downward, and the stamping plate 3 of the second mounting hole 31 punches the middle part of the plate member 2 under the drive of the second cylinder 33. After punching is completed, the pressing block 13 in the first mounting hole 12 on the base 1 pushes up the middle part of the plate member 2 upward to form a convex structure, so that the plate member 2 is integrally formed into a chimney cover.
[0050] Finally, the motor 43 drives the bidirectional screw 42 to rotate to open the limit groove 11, and the plate member 2 will slide out of the limit groove 11 with the assistance of manpower.
[0051] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
