Description

Technical Field

[0001] The invention relates to the technical field of outdoor unit top cover production, in particular to a stamping device and method for producing outdoor unit top covers with demoulding deformation and correctable deviation. Background Art

[0002] Stamping dies are special process equipment used to process materials into parts during cold stamping. They are called cold stamping dies. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the desired parts. Dies refer to various molds and tools used in industrial production to obtain the desired products by methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, and stamping. In short, a mold is a tool used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material.

[0003] During the production and processing of the outdoor unit top cover, the shell is placed inside the stamping die. Under the stamping pressure, the shell is formed, and then the formed workpiece is smoothly demolded through hydraulic operation. However, during the demolding process, the corners of the formed workpiece and the corners of the mold cavity are easily subjected to friction, resulting in corner depressions. Even through methods such as adding lubricating oil, as long as the extrusion force exists, the corners of the formed workpiece will be deformed to a certain extent, affecting the yield rate of the outdoor unit top cover production workpiece.

[0009] Furthermore, a shaking assembly is arranged inside the upper slot, and an extension control part is installed on the upper end of the shaking assembly.

[0017] Another technical solution proposed by the present invention is to provide an implementation method of a stamping device with correctable demoulding deformation for producing an outdoor unit top cover, comprising the following steps:

[0018] S1: The demoulding component is separated from the die cavity of the stamping die, driving the formed workpiece to also be separated from the die cavity. The driving turntable drives the shifting bar frame to slide along the inner sides of the two sets of limit clamp covers through the traction block. The two sets of shifting bar frames drive the first sliding matching block and the second sliding matching block to slide along the two sets of bidirectional connecting grooves respectively. The distance between the first sliding matching block and the second sliding matching block is getting closer and closer, and the connecting traction rope, which was originally in a taut state, gradually changes to a relaxed state.

[0019] S2: The first separation block and the second separation block, which are perpendicular to each other, lose the traction limiting force of the traction rope connected to them, and then the swing control rod swings outward along the upper receiving slot, and the first separation block and the second separation block both flip outward;

[0020] S3: When the first separation block and the second separation block lose the mutual pulling force with the connecting traction rope, the rotating shaft column drives the top pressure rod to rotate through the swing side rod. The length of the top pressure rod matches the vertical distance of the shaking assembly. When the top pressure rod rotates normally, there is a certain gap between the top of the top pressure rod and the bottom surface of the shaking assembly.

[0021] S4: When the top of the top pressure rod is connected to the arc-shaped connection protrusion on the bottom surface of the auxiliary force splicing plate, the auxiliary force splicing plate tilts, the vertical connection support bar and the connection support cover tilt accordingly, and the movable splicing rotating column rotates along the rotating circular groove;

[0022] S5: In the initial state, the first cam and the second cam in the staggered state can keep the triangular frame in a vertical state, and the first cam and the second cam make the triangular frame in an inclined state. The triangular frame drives the first separation block and the second separation block to tilt outward through the sliding splicing rod, so that there is enough gap between the corner of the formed workpiece and the extended demolding part. At this point, all implementation steps are completed.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention proposes a stamping device and method with correctable demolding deformation for outdoor unit top cover production. By continuously approaching the distance between the first sliding matching block and the second sliding matching block, the connection traction rope, which was originally in a taut state, gradually changes into a relaxed state, and the mutually perpendicular first separation block and the second separation block lose the traction limiting force of the connection traction rope on them, and the four sides of the formed workpiece are separated from the outer mold body to facilitate rapid demolding of the molding module. The extended demolding part only has the freedom of lifting and lowering inside the mold. When the molding module is pushed out of the mold cavity, the extended demolding part increases the freedom of extendable movement, thereby avoiding the problem of friction, extrusion and deformation of the molding module corners during the extrusion demolding process.

[0025] 2. The present invention proposes a stamping device and method with correctable demolding deformation for the production of outdoor unit top covers. There is a certain gap between the top of the small pressing rod and the lower bottom surface of the shaking assembly, which will not cause force influence on the shaking assembly. The combined height of the small pressing rod and the arc-shaped connecting protrusion is greater than the distance between the shaking assembly and the swing side rod. When the small pressing rod is continuously rotated, the shaking assembly may exhibit intermittent tilting and vibration activities, and the swinging control rod drives the first separation block and the second separation block to vibrate intermittently with each other, which is beneficial to the separation of the first separation block and the second separation block from the outer surface of the formed workpiece, thereby improving the smoothness of subsequent demolding.

[0026] 3. The present invention proposes a stamping device and method with correctable demoulding deformation for producing outdoor unit top covers. The first cam and the second cam make the triangular frame in an inclined state. The triangular frame drives the first separation block and the second separation block to tilt outward through the sliding splicing rod, so that there is enough gap between the corner of the formed workpiece and the extended demoulding part, which is convenient for separating the formed workpiece from the mold cavity. Combined with the intermittent tilting and shaking activities of the shaking assembly, it is beneficial to improve the integrity of the formed workpiece during demoulding and improve the yield rate of the workpiece in the production of outdoor unit top covers.

[0044] Specifically, the hydraulic operation of the stamping block 4 by the lifting bracket 3 causes the stamping block 4 to stamp out the shell workpiece inside the stamping die 2, and the stamping base 1 applies hydraulic lifting operation to the bottom of the demolding component 6 again, so that the demolding component 6 gradually separates from the die cavity of the stamping die 2, thereby driving the formed workpiece to also separate from the die cavity, and start the driving turntable 6255.

The distance between the first sliding matching block 6281 and the second sliding matching block 6282 is not As the two pieces get closer and closer, the taut connecting rope 6283 gradually changes into a relaxed state, and the mutually perpendicular first separating block 621 and second separating block 622 lose the traction limiting force of the connecting traction rope 6283, and then the swing control rod 6233 is swung outward along the accommodating upper slot 6232, and the first separating block 621 and the second separating block 622 are both flipped outward, so that the surrounding surfaces of the formed workpiece are separated from the outer mold body, so as to facilitate the rapid demolding of the molding module, and the extended demolding member 62 only has the freedom of lifting and lowering inside the mold, and when the molding module is pushed out of the mold cavity, the extended demolding member 62 increases the freedom of the extendable movement, thereby avoiding the problem of friction, extrusion and deformation of the molding module corners during the extrusion demolding process.

[0045] In order to solve the technical problems of smoothness during demoulding, such as Figure 3-Figure 10As shown, the following preferred technical solutions are provided:

[0046] A shaking assembly 6234 is arranged inside the upper slot 6232, an extension control member 6235 is installed on the upper end of the shaking assembly 6234, a control base 62321 is installed on the inner bottom surface of the upper slot 6232, a rotating shaft column 62322 is arranged on the upper surface of the control base 62321, a swing side rod 62323 is installed on the side surface of one end of the rotating shaft column 62322, a top pressure rod 62324 is arranged at the center of the upper surface of the swing side rod 62323, the size of the top pressure rod 62324 matches the distance between the swing side rod 62323 and the shaking assembly 6234, rotating circular grooves 62325 are arranged on both side walls inside the upper slot 6232, and the shaking assembly 6234 includes a connecting support cover 62341 arranged inside the upper slot 6232 and a connecting support cover 62341 installed on the connecting support cover The cover 62341 is provided with movable splicing rotating columns 62342 on both outer facades, and the movable splicing rotating columns 62342 are connected to the rotating circular groove 62325. An auxiliary force splicing plate 62343 is installed at the lower end of the connecting support cover 62341. Vertical connecting struts 62345 are installed on both side ends of the upper surface of the auxiliary force splicing plate 62343. A movable connecting piece 62344 is arranged on the side surface of one end of the vertical connecting strut 62345. Two groups of movable connecting pieces 62344 are installed on the two inner side walls of the connecting support cover 62341, and the two groups of movable connecting pieces 62344 correspond to the vertical lines of the two groups of movable splicing rotating columns 62342.

The length of the top pressure rod 623424 matches the vertical distance of the shaking assembly 6234. When the top pressure rod 623424 rotates normally, there is a certain gap between the top of the top pressure rod 623424 and the lower bottom surface of the shaking assembly 6234, which will not cause force to the shaking assembly 6234. When the top of the top pressure rod 623424 is connected with the arc-shaped connecting protrusion 62346 on the bottom surface of the auxiliary force splicing plate 62343, the top pressure rod 623424 and the arc-shaped connecting protrusion 623 The combined height of 46 is greater than the distance between the shaking assembly 6234 and the swing side rod 62323, and the arc-shaped connecting protrusion 62346 corresponds to the vertical line of the two sets of movable splicing rotating columns (62342), the auxiliary force splicing plate 62343 is tilted, and the vertical connecting support bar 62345 and the connecting support cover 62341 are tilted accordingly, and the movable splicing rotating column 62342 is limitedly rotated along the rotating circular groove 62325, and then under the condition that the top pressure rod 623424 is continuously rotated, the shaking assembly 6234 can intermittently tilt and vibrate, and the swing control rod 6233 drives the first separation block 621 and the second separation block 622 to vibrate intermittently with each other, which is beneficial to the separation of the first separation block 621 and the second separation block 622 from the outer surface of the formed workpiece, thereby improving the smoothness of subsequent demolding.

[0048] In order to better solve the technical problems of integrity during demoulding, such as Figure 9-11 As shown, the following preferred technical solutions are provided:

[0049] One end of the swing control rod 6233 is connected to the lower surface of the first separation block 621 and the second separation block 622, and the other end of the swing control rod 6233 is provided with a triangular frame 62331, which is arranged inside the upper slot 6232. A connecting block 62332 is installed on the lower surface of the triangular frame 62331, and a movable rotating ball 62333 is installed on the lower end of the connecting block 62332. The swing control rod 6233 is connected to the upper surface of the supporting cover 62341 through the movable rotating ball 62333. The extension control part 6235 includes a semi-fan-shaped back plate 62351 arranged on the upper surface of the connecting support cover 62341 and a first cam 62352 installed on one side of the semi-fan-shaped back plate 62351, the semi-fan-shaped back plate 62351 is installed on one side of the triangular frame 62331, the first cam 62352 is arranged on one side of the triangular frame 62331, and the second cam 62353 is arranged on the other side of the triangular frame 62331, and the protrusion positions of the first cam 62352 and the second cam 62353 are staggered.

[0050] Specifically, in the initial state, the convex block positions of the first cam 62352 and the second cam 62353 are staggered, and the first cam 62352 and the second cam 62353 in the staggered state can keep the triangular frame 62331 in a vertical state. When the first separation block 621 and the second separation block 622 are separated from the outer surface of the formed workpiece, the first cam 62352 and the second cam 62353 are started, so that the triangular frame 62331 is in a tilted state, and the triangular frame 62331 drives the first separation block 621 and the second separation block 622 to tilt outward through the sliding splicing rod 6256, so that there is enough gap between the corner of the formed workpiece and the extended demolding part 62, which is convenient for separating the formed workpiece from the mold cavity. In combination with the intermittent tilting and shaking activities of the shaking assembly 6234, it is beneficial to improve the integrity of the formed workpiece during demolding and improve the yield rate of the outdoor unit top cover production workpiece.

[0051] In order to further better explain the above embodiment, the present invention also provides an implementation scheme, an implementation method of a stamping device with correctable demolding deformation for producing an outdoor unit top cover, comprising the following steps:

[0052] Step 1: The demoulding assembly 6 is separated from the die cavity of the stamping die 2, driving the formed workpiece to also be separated from the die cavity. The driving turntable 6255 drives the shifting bar frame 6253 to slide along the inner sides of the two sets of limit clamp covers 6251 through the traction block 6254. The two sets of shifting bar frames 6253 drive the first sliding matching block 6281 and the second sliding matching block 6282 to slide along the two sets of two-way connecting grooves 624 respectively. The distance between the first sliding matching block 6281 and the second sliding matching block 6282 is constantly approaching, and the connecting traction rope 6283, which was originally in a taut state, gradually changes to a relaxed state.

[0053] Step 2: The first separation block 621 and the second separation block 622 which are perpendicular to each other lose the traction limiting force of the connecting traction rope 6283, and then the swing control rod 6233 swings outward along the receiving upper slot 6232, and the first separation block 621 and the second separation block 622 both flip outward;

[0054] Step 3: When the first separation block 621 and the second separation block 622 lose the pulling force on the connecting traction rope 6283, the rotating shaft column 62322 drives the top-pressing rod 623424 to rotate through the swinging side rod 62323. The length of the top-pressing rod 623424 matches the vertical distance of the shaking assembly 6234. When the top-pressing rod 623424 rotates normally, there is a certain gap between the top of the top-pressing rod 623424 and the bottom surface of the shaking assembly 6234.

[0055] Step 4: When the top of the pressing rod 623424 is connected to the arc-shaped connecting protrusion 62346 on the bottom surface of the auxiliary force splicing plate 62343, the auxiliary force splicing plate 62343 tilts, and the vertical connection support bar 62345 and the connection support cover 62341 tilt accordingly, and the movable splicing rotating column 62342 rotates along the rotating circular groove 62325;

[0056] Step 5: In the initial state, the first cam 62352 and the second cam 62353 in the staggered state can keep the triangular frame 62331 in a vertical state, and the first cam 62352 and the second cam 62353 make the triangular frame 62331 in an inclined state. The triangular frame 62331 drives the first separation block 621 and the second separation block 622 to tilt outward through the sliding splicing rod 6256, so that there is enough gap between the corner of the formed workpiece and the extended demolding part 62. At this point, all the implementation steps are completed.
