Description

Technical Field

[0001] The invention relates to the technical field of washing machine inner drum processing, in particular to a stamping processing and forming device for a washing machine inner drum. Background Art

[0002] Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject sheet materials to deformation force in the mold, thereby obtaining product parts with certain shapes, sizes and performances. When processing the inner drum of a washing machine, stamping is generally used. The sheet materials for making the inner drum of the washing machine are placed on the stamping equipment for stamping, so that the sheet materials are stamped into the required shape of the inner drum of the washing machine.

[0003] When the inner drum of a washing machine is stamped, a forming mold with the same shape as that required by the inner drum of the washing machine is generally provided on the stamping equipment. When the material plate is stamped by the forming mold, the required shape of the inner drum of the washing machine is formed. However, during the use of the forming mold, some debris impurities will be generated when the material plate of the inner drum of the washing machine is stamped. These impurities may remain on the forming mold. If the material plate of the inner drum of the washing machine is directly placed on the forming mold containing debris impurities, during stamping, since the debris impurities are raised substances, some pits may exist on the formed inner drum of the washing machine, thereby reducing the quality of the inner drum of the washing machine during molding and reducing the qualified rate of the inner drum of the washing machine during processing.

[0015] The present invention has the following beneficial effects: 1. In the stamping processing and forming equipment of the inner drum of the washing machine, before the raw material plate of the inner drum of the washing machine is stamped, the surface of the forming mold can be blown and impurities are removed through the blowing pipe, so as to facilitate the removal of debris and impurities on the surface of the forming mold. When the blowing pipe is used to blow air at the forming mold, the punching head drives the rotating ring to rotate, and the rotating ring drives the connecting column to slide in the first track groove, so that the blowing pipe can blow air along the forming mold, so that the closest distance between the blowing pipe and the forming mold remains unchanged during the movement, which is beneficial to improve the effect of blowing and impurity removal. In addition, after the inner drum of the washing machine is stamped and formed, the inner drum of the washing machine after stamping and forming is taken out, and the forming mold can be blown and impurities are removed for the second time through the resetting movement of the blowing pipe, thereby further increasing the effect of impurity removal and preventing the situation that there may be some pits on the inner drum of the washing machine caused by debris and impurities, which is beneficial to improve the quality of the inner drum of the washing machine during molding.

[0016] 2. In the stamping and forming equipment for the inner drum of the washing machine, when the connecting column drives the air blowing pipe to slide along the first track, the air blowing pipe drives the sliding rod to slide inside the second track groove, and the sliding rod can reciprocate up and down through the provided descending part and ascending part. At the same time, the air blowing pipe can rotate through the hinged seat through the rotating block. When the sliding rod reciprocates up and down, the air blowing pipe drives the air blowing pipe to swing up and down, so that the air blowing pipe can blow air to the bottom and top of the forming mold when blowing, thereby increasing the blowing range of the air blowing pipe and improving the blowing effect; 3. In the stamping processing and forming equipment of the inner drum of the washing machine, when the slide rod slides inside the second track groove, the slide rod drives the core rod to slide inside the third track groove. When the slide rod slides downward in the descending part, the core rod slides inside the first inclined part, so that the core rod slides toward the inside of the slide rod. At this time, the core rod drives the moving rod to move, the moving rod drives the straight rod to move, and the straight rod drives the blocking block to move, so as to move the blocking block out of the storage groove. The blocking block is used to change the opening size of the blowing groove, so that when the blowing groove is blown to the top of the molding mold which is far away, the opening size of the blowing groove is reduced, and the power of gas blowing is increased, so that the gas is blown farther, thereby improving the blowing and impurity removal effect of the blowing pipe on the top of the molding mold.

DETAILED DESCRIPTION

[0028] 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.

[0029] For example, see Figure 1-Figure 10 A stamping and forming device for a washing machine inner drum comprises a stamping machine body 1, a processing table 2 is fixed at the bottom of the stamping machine body 1, a forming die 3 is arranged on the processing table 2, a stamping head 4 is arranged on the top of the stamping machine body 1, and the stamping head 4 is pressed with the processing table 2 by moving up and down to stamp and form the raw material plate of the washing machine inner drum; A support plate 5 is fixed at the bottom of the punching machine body 1, a fixed ring 6 is fixed at the top of the support plate 5, a rotating ring 7 is rotatably provided on the fixed ring 6, the punching head 4 passes through the fixed ring 6 and the rotating ring 7, the rotating ring 7 rotates by the up and down movement of the punching head 4, a connecting column 8 is slidably connected to the lower surface of the rotating ring 7, and a blowing pipe 9 for blowing and removing impurities to the forming mold 3 is provided at the bottom of the connecting column 8, and the blowing pipe 9 rotates with the rotation of the rotating ring 7 to perform mobile blowing on the forming mold 3; A protruding column 10 is fixed on the outer surface of the punch head 4, and a spiral groove 11 and a vertical groove 37 for the protruding column 10 to slide are formed on the inner surface of the rotating ring 7, and the spiral groove 11 and the vertical groove 37 are connected to each other; A cylindrical groove 12 is provided inside the rotating ring 7, a limiting ball 13 is slidably arranged in the cylindrical groove 12, and the top of the connecting column 8 is fixedly connected to the limiting ball 13; The lower surface of the rotating ring 7 is provided with a slideway 14 for the connecting column 8 to slide, and the fixed ring 6 is provided with a first track groove 15 for the connecting column 8 to slide; A blower 35 is provided on one side of the air blowing pipe 9, and the output end of the blower 35 is connected to an air supply pipe 36, and the other end of the air supply pipe 36 is connected to the air blowing pipe 9; the blower 35 can be set on the side plate 18 of the present application, or on the punching machine body 1, as long as it does not affect the air supply to the air blowing pipe 9.

[0030] In this technical solution, the punching machine body 1 is a prior art, which can drive the punching head 4 to move upward and downward, but it is not an innovation of this application and will not be described in detail. Moreover, the forming die 3 in this application has the same shape as the inner drum of the washing machine to be pressed, such as Figure 1 and Figure 6 As shown, the forming mold 3 is set to a convex structure with three sides having the same curvature, the track of the first track groove 15 is the same as the track of the side a of the forming mold 3, and the blowing pipe 9 is arranged corresponding to the number of sides of the forming mold 3, so that each group of blowing pipes 9 blows and removes impurities on one side of the forming mold 3, and the shape of the forming mold 3 is not limited to the shape in the present application; When the inner drum of the washing machine is subjected to stamping processing, the raw material plate of the inner drum of the washing machine is first placed on the processing table 2, and then the punching head 4 moves downward to make the punching head 4 fit the processing table 2, and the raw material plate of the inner drum of the washing machine is stamped and formed by the forming mold 3, and then the punching head 4 moves upward to remove the formed inner drum of the washing machine from the processing table 2, thereby completing the stamping and forming work of the inner drum of the washing machine.

[0031] When the inner drum of the washing machine is punched, the specific process is as follows: first, while the punch head 4 moves downward, the blower 35 is turned on, so that the blower 35 blows gas from the blowing pipe 9 through the air pipe 36 to blow and remove impurities from the forming mold 3, and the punch head 4 moves downward to drive the protrusion 10 to move downward, and the protrusion 10 moves downward to conflict with the spiral groove 11, so that the protrusion 10 slides in the spiral groove 11, and at the same time drives the rotating ring 7 to rotate, and the rotation of the rotating ring 7 drives the connecting column 8 to rotate, and the rotation of the connecting column 8 drives the blowing pipe 9 to move, such as Figure 6 As shown in FIG. 1 , due to the restriction of the first track groove 15, the connecting column 8 will slide along the first track groove 15 when rotating, so the track of the first track groove 15 is the same as the track of one side of the forming mold 3, so that the closest distance between the connecting column 8 and the forming mold 3 remains unchanged when rotating, so that the closest distance between the blowing pipe 9 and the forming mold 3 remains unchanged when moving, thereby improving the impurity removal effect of the blowing pipe 9 on the surface of the forming mold 3. In order to enable the connecting column 8 to slide along the first track groove 15, as shown in FIG. Figure 6 As shown, a slideway 14 is provided on the rotating ring 7, so that the connecting column 8 can slide along the slideway 14 while sliding in the first track groove 15, thereby preventing the connecting column 8 from being stuck; When the connecting column 8 slides from one end of the first track groove 15 to the other end, the blowing pipe 9 also slides from one end of the molding die 3 to the other end, completing the blowing and impurity removal work on the surface of the molding die 3. The blower 35 is turned off, and the blowing pipe 9 stops blowing. At this time, the punch head 4 drives the protruding column 10 to move downward from the spiral groove 11 to the vertical groove 37. At this time, the punch head 4 stops moving downward. After the worker puts the raw material plate of the washing machine inner drum into the corresponding position on the processing table 2, the punch head 4 continues to move downward. At this time, the punch head 4 drives the protruding column 10 to slide in the vertical groove 37 until it slides out from the inside of the vertical groove 37, and will no longer drive the rotating ring 7 to rotate until the punch head 4 fits with the processing table 2, and the raw material plate of the washing machine inner drum is punched and formed by the molding die 3; When performing the reset movement, the punch head 4 moves upward, and the worker removes the formed washing machine inner drum from the processing table 2. The punch head 4 moves upward to drive the boss 10 to move upward, so that the boss 10 first slides into the vertical groove 37 and moves upward along the vertical groove 37. When the boss 10 moves into the spiral groove 11 again, the rotating ring 7 starts to rotate in the opposite direction to reset. At this time, the air blowing pipe 9 also moves in the opposite direction to reset. When the air blowing pipe 9 moves in the opposite direction to reset, the blower 35 is turned on to make the air blowing pipe 9 blow again, so that the secondary air blowing and impurity removal treatment of the forming mold 3 can be realized, which increases the time of air impurity removal and further improves the sufficiency of air impurity removal until the punch head 4 moves upward and resets. In the present technical solution, the bottom of the vertical groove 37 is set to a trumpet-shaped opening structure, and there is a large friction force between the rotating ring 7 and the fixed ring 6, so that the rotating ring 7 will not rotate without the drive of the punch head 4. Even after the punch head 4 drives the boss 10 to slide out of the vertical groove 37, the rotating ring 7 undergoes a small amount of deflection. The trumpet-shaped opening structure at the bottom of the vertical groove 37 can ensure that the boss 10 slides into the vertical groove 37, which has a correction function and is easy to reset.

[0032] In the second embodiment, when the air blowing pipe 9 blows along the forming mold 3, since the air blowing pipe 9 always moves along the same horizontal plane, the air blowing pipe 9 also blows along the same horizontal plane of the forming mold 3, thereby reducing the scope of the air blowing and impurity removal, affecting the adequacy of the air blowing and impurity removal. To address this problem, this embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figure 1-Figure 10 A hinge seat 16 is fixed to the bottom end of the connecting column 8, a rotating block 17 is fixed to the upper surface of the blowing pipe 9, and the rotating block 17 is rotatably connected to the hinge seat 16 through a pin shaft. A side plate 18 is fixed to the lower surface of the fixing ring 6, and a second track groove 19 is opened on the outer surface of the side plate 18. A sliding rod 20 is fixed to the end of the blowing pipe 9, and the end of the sliding rod 20 is slidably arranged in the second track groove 19; The second track groove 19 includes a descending portion 191 and an ascending portion 192 which are sequentially connected and arranged.

[0033] In the present technical solution, the track of the outer surface of the side plate 18 is the same as the track of the first track groove 15, so that when the connecting column 8 moves, the distance between it and the side plate 18 remains the same; when the connecting column 8 slides along the first track groove 15, the air blowing pipe 9 moves with the connecting column 8, and at this time, the air blowing pipe 9 drives the sliding rod 20 to slide in the second track groove 19, such as Figure 4 As shown, when the slide bar 20 slides along the descending portion 191 of the second track groove 19, the slide bar 20 first slides along the descending portion 191 due to the resistance of the descending portion 191, so that the slide bar 20 moves downward. Since the air blowing pipe 9 is rotatably connected to the hinge seat 16 through the rotating block 17, when the slide bar 20 moves downward, it will drive the other end of the air blowing pipe 9 to move upward, so that the air blowing pipe 9 moves from the bottom position of the molding die 3 to the top of the molding die 3. When the slide bar 20 slides along the ascending portion 192 of the second track groove 19, the slide bar 20 slides along the ascending portion 192 due to the resistance of the ascending portion 192, so that the slide bar 20 moves upward. At this time, the slide bar 20 drives the air blowing pipe 9 to rotate, so that the other end of the air blowing pipe 9 moves downward. At this time, the air blowing pipe 9 is moved from blowing toward the top of the molding die 3 to blowing toward the bottom of the molding die 3. In summary, when the connecting column 8 slides along the first track groove 15, the connecting column 8 will drive the blowing pipe 9 to move synchronously, and the blowing pipe 9 will drive the sliding rod 20 to slide inside the second track groove 19. The descending portion 191 and the ascending portion 192 provided in the second track groove 19 enable the sliding rod 20 to reciprocate up and down. The up and down reciprocating motion of the sliding rod 20 drives the blowing pipe 9 to reciprocate up and down, so that the blowing pipe 9 can swing up and down along the molding mold 3 to realize up and down reciprocating blowing, thereby increasing the blowing range of the blowing pipe 9, thereby further improving the adequacy of the blowing pipe 9 in removing impurities by blowing.

[0034] In the third embodiment, when the air blowing pipe 9 blows from the bottom of the forming mold 3 to the top of the forming mold 3, since the distance between the air blowing pipe 9 and the top of the forming mold 3 is farther than the distance from the bottom of the forming mold 3, and the opening size of the air blowing slot 22 of the air blowing pipe 9 is the same, therefore, when the air blowing pipe 9 blows to the top of the forming mold 3 which is farther away, the power of the air blowing is smaller. At the position where the air blowing power is smaller, it is not convenient to blow away the impurities, thereby reducing the air blowing and impurity removal effect on the top of the forming mold 3. In view of this problem, this embodiment is an improvement made on the basis of the second embodiment. For details, please refer to Figure 1-Figure 10The blowing pipe 9 is provided with an air supply groove 21 and an air blowing groove 22 which are interconnected. A moving rod 23 is slidably arranged in the air supply groove 21. A core rod 24 is slidably arranged inside the slide rod 20. The end of the core rod 24 is fixedly connected to the moving rod 23. A third track groove 25 for sliding the end of the core rod 24 is provided inside the side plate 18. A straight rod 26 is fixed on the surface of the moving rod 23. The straight rod 26 is elastically arranged in the blowing pipe 9. Receiving grooves 27 are provided on both sides of the air blowing groove 22. A blocking block 28 is elastically connected in the receiving groove 27. The third track groove 25 includes a first inclined portion 251 and a second inclined portion 252 which are connected in sequence; A spring groove 29 is provided inside the air blowing tube 9, a convex plate 30 is fixed on the outer surface of the straight rod 26, the convex plate 30 is slidably set in the spring groove 29, a spring 31 is provided between the convex plate 30 and the inner wall of the spring groove 29, a sliding groove 32 is provided on the blocking block 28, the end of the straight rod 26 is slidably set in the sliding groove 32, and a resisting inclined groove 33 is provided on the inner wall of the sliding groove 32, and a sliding protrusion 34 slidably set inside the resisting inclined groove 33 is fixed to the end of the straight rod 26.

[0035] In this technical solution, the horizontal track of the third track groove 25 is Figure 4 The track of the second track groove 19 is the same. When the slide bar 20 slides along the second track groove 19, the slide bar 20 drives the core rod 24 to slide along the third track groove 25. When the slide bar 20 slides in the descending portion 191 of the second track groove 19, the slide bar 20 moves downward. Figure 7 As shown, at this time, the slide bar 20 drives the core rod 24 to move downward, so that the end of the core rod 24 slides downward along the third track groove 25. Due to the interference of the third track groove 25, the core rod 24 slides toward the inside of the slide bar 20. Figure 8 , when the slide bar 20 slides along the second track groove 19, the slide bar 20 drives the core rod 24 to slide on the first inclined portion 251 of the third track groove 25. Due to the interference of the first inclined portion 251 with the end of the core rod 24, the core rod 24 moves to the left, and the core rod 24 moves to the left, driving the moving rod 23 to move to the left inside the air supply groove 21. The moving rod 23 drives the straight rod 26 to move to the left, and the straight rod 26 drives the convex plate 30 to move to the left, and at the same time compresses the spring 31, so that the spring 31 accumulates force, and the straight rod 26 moves to the left, driving the sliding protrusion 34 to move to the left, as shown in FIG. Fig. 9As shown, due to the interference of the oblique groove 33 with the sliding protrusion 34, when the sliding protrusion 34 moves to the left, in order to be able to slide along the oblique groove 33, the sliding protrusion 34 will drive the blocking block 28 to slide inside the storage groove 27, so that the blocking block 28 moves to one side of the blowing groove 22, so that the opening of the blowing groove 22 is gradually reduced by the blocking block 28, and the gas pressure inside the air supply groove 21 is increased by the reduced blowing groove 22, thereby increasing the blowing distance, so that when the blowing pipe 9 blows to the top of the forming mold 3, the power of the gas will not decrease, which is convenient for blowing the top of the forming mold 3, and increases the sufficiency of the blowing pipe 9 to blow and remove impurities when blowing to the top of the forming mold 3; When the slide bar 20 slides to the rising portion 192, the slide bar 20 moves upward, and at this time the slide bar 20 drives the core rod 24 to slide on the second inclined portion 252 of the third track groove 25. At this time, the end of the core rod 24 loses the resistance, and the spring 31 releases the force, so that the straight rod 26 performs a reset movement to the right, and the straight rod 26 drives the moving rod 23 to perform a reset movement to the right, and the moving rod 23 drives the core rod 24 to move to the right, so that the core rod 24 slides along the inner wall of the second inclined portion 252. At this time, when the straight rod 26 performs a reset movement to the right, the straight rod 26 drives the sliding protrusion 34 to move to the right, so that the sliding protrusion 34 slides in the resisting inclined groove 33, thereby driving the blocking block 28 to move, and the blocking block 28 is moved to the storage groove 27 again, and the blowing groove 22 is opened; In summary, when the blowing groove 22 of the blowing pipe 9 moves from bottom to top, that is, when the blowing pipe 9 moves from the bottom to the top of the forming mold 3, the opening of the blowing groove 22 changes from large to small, so that the gas can be blown to a farther position; when the blowing groove 22 of the blowing pipe 9 moves from top to bottom, that is, when the blowing pipe 9 moves from the top to the bottom of the forming mold 3, the opening of the blowing groove 22 changes from small to large, so that the blowing groove 22 is reset to its initial state.

[0036] In this technical solution, if Fig.10 As shown, the top of the blocking block 28 is configured as a cut surface structure, which can facilitate gas conduction and gas discharge.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
