[0043] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0044] like Figures 1 to 13 As shown, this application provides:

[0045] An automatic stamping and forming device for a clutch flange of a washing machine is characterized in that it comprises a base 1, an upper hydraulic cylinder 1a is fixedly installed on the top of the base 1, and a lower hydraulic cylinder 1b is fixedly installed on the bottom of the base 1; a pressing plate 1a1 is fixedly installed on the working end of the upper hydraulic cylinder 1a, and a plurality of upper die seats 2 are fixedly installed on the lower side of the pressing plate 1a1; the upper die seats 2 are evenly spaced along the length direction of the pressing plate 1a1, and an upper die core 2a is arranged on the upper die seat 2; a stamping platform 3 is fixedly installed on the base 1, the stamping platform 3 is horizontally arranged below the pressing plate 1a1, and a plurality of insertion holes 3a are arranged on the stamping platform 3; a supporting plate 1b1 is fixedly installed on the working end of the lower hydraulic cylinder 1b, and a plurality of lower die seats 4 are fixedly installed on the upper side of the supporting plate 1b1; the lower die seat 4 The axis of the lower die base 4 corresponds to the axis of the insertion hole 3a, and the axis position of the lower die base 4 is provided with an axial hole 4a, and the sleeve 5a of the workpiece blank 5 is inserted in the axial hole 4a; the support plate 1b1 is provided with a plurality of first through holes 1b2 corresponding to the axial hole 4a; the lower die base 4 also includes a plurality of second positioning blocks 4b, and the second positioning blocks 4b are inserted in the second through holes 5b; the base 1 is also equipped with a fixed platform 1c, and the fixed platform 1c is located below the support plate 1b1, and the working end of the lower hydraulic cylinder 1b passes through the fixed platform 1c and is connected to the bottom of the support plate 1b1, and a plurality of ejecting rods 1c1 are provided on the fixed platform 1c, and the ejecting rods 1c1 are used to eject the sleeve 5a of the workpiece blank 5 out of the axial hole 4a of the lower die base 4; the unloading device 6 is fixedly installed on one side of the base 1.

[0046] The stamping platform 3 installed on the base 1 and the multiple lower die seats 4 installed on the support plate 1b1 of the lower hydraulic cylinder 1b form a mold for placing the workpiece blank 5. During processing, the working end of the lower hydraulic cylinder 1b moves up to fit the support plate 1b1 to the bottom of the stamping platform 3. At this time, the top of the axial hole 4a is kept horizontal with the top of the stamping platform 3. The staff manually or automatically inserts the shaft sleeve 5a of the workpiece blank 5 into the axial hole 4a of the lower die seat 4 by a robot arm. When the workpiece blank 5 is rotated, the second positioning block 4b on the lower die seat 4 can be inserted into the second through hole 5b of the workpiece blank 5 to position the workpiece blank 5 to prevent the workpiece blank 5 from rotating and deviating during the stamping process and affecting the processing effect. After the workpiece blank 5 is installed, the upper hydraulic cylinder 1a drives the pressing plate 1a1 to move downward, so that the upper die seat installed on the pressing plate 1a1 2 is molded with the lower die base 4 to complete the stamping of the workpiece blank 5.

After the processing is completed, the upper hydraulic cylinder 1a drives the upper die base 2 to move up and reset, and the lower hydraulic cylinder 1b drives the lower die base 4 and the flange stamped on the lower die base 4 to move down. At this time, the ejector rod 1c1 on the fixed platform 1c under the support plate 1b1 is inserted from the bottom of the axial hole 4a of the lower die base 4, and the flange inserted in the axial hole 4a is lifted upward. The unloading device 6 moves horizontally to clamp and fix the shaft sleeve 5a of the flange. When the flange is completely separated from the lower die base 4, it is moved out horizontally, and then the lower hydraulic cylinder 1b drives the lower die base 4 to reset, and the workpiece blank 5 is loaded again to complete the next processing.

[0047] Further, such as Figure 4 , Fig.10 and Fig.11 As shown:

[0048] A plurality of external gear molding devices 3b are fixedly installed on the stamping platform 3; the external gear molding devices 3b include external gear molds 3b1 arranged on both sides of each insertion hole 3a, and the external gear molds 3b1 cooperate with the stamping tooth grooves 2a1 on the upper mold core 2a to stamp the tooth grooves of the workpiece blank 5. The external gear mold 3b1 is provided with a horizontally extending connecting rod 3b2, and the connecting rods 3b2 on both sides of the insertion hole 3a are provided with racks 3b3 extending horizontally along the length direction of the connecting rods 3b2; the racks 3b3 are slidably installed in the limiting slide grooves 3c of the stamping platform 3, and the limiting slide grooves 3c extend along the length direction of the stamping platform 3; the gear 3d is meshed and connected with the racks 3b3 of the external gear molds 3b1 on both sides of the insertion hole 3a, and the shaft 3d1 at the axis position of the gear 3d is inserted on the stamping platform 3.

[0049] The external gear molds 3b1 installed on both sides of the insertion hole 3a of the stamping platform 3 cooperate with the stamping tooth grooves 2a1 set on the upper mold core 2a of the upper mold base 2 to stamp the tooth grooves of the workpiece blank 5. The two external gear molding devices 3b are driven by the gear 3d to expand to both sides to facilitate the staff to install the workpiece blank 5 in the axial hole 4a of the lower mold base 4. During processing, the gear 3d rotates to drive the two external gear molds 3b1 to be close and spliced ​​to form an external gear mold cavity, and cooperates with the upper mold base 2 to complete the stamping. After the stamping is completed, the gear 3d drives the external gear mold 3b1 to expand again to facilitate the lower mold base 4 to drive the flange to unload the material.

[0050] Further, such as Fig.10 and Fig.11 As shown:

[0051] The shafts 3d1 of two adjacent gears 3d are connected through a first transmission belt 3d2; a first rotary drive device 3d3 is fixedly installed on one side of the stamping platform 3, the rotation axis of the first rotary drive device 3d3 is parallel to the axis of the shaft 3d1, and the first rotary drive device 3d3 is connected to the shaft 3d1 of the gear 3d through a second transmission belt 3d4.

[0052] The first transmission belt 3d2 transmits the shaft 3d1 connecting two adjacent gears 3d so that when the first rotation drive device 3d3 drives one of the gears 3d to rotate through the second transmission belt 3d4, all the gears 3d can be driven to rotate synchronously, thereby driving the synchronous adjustment of the external gear molding device 3b to achieve synchronous processing of multiple workpiece blanks 5. The first rotation drive device 3d3 can be a servo motor.

[0053] Further, such as Figure 4 , Figure 5 and Fig. 9 As shown:

[0054] A plurality of first positioning blocks 2a2 are provided on the upper die core 2a of the upper die base 2, and the axis of the first positioning block 2a2 is in the same straight line as the axis of the second positioning block 4b of the lower die base 4; a plurality of inner grooves 4c extending vertically upward are provided on the lower die base 4, and the second positioning block 4b is inserted in the inner groove 4c, and a spring 4c1 is provided in the inner groove 4c, and the spring 4c1 elastically connects the bottom of the inner groove 4c and the bottom of the second positioning block 4b.

[0055] The second positioning block 4b is inserted in the inner groove 4c of the lower die base 4 and is kept protruding from the surface of the lower die base 4 by the elastic force of the spring 4c1 to position the workpiece blank 5. When the upper die base 2 and the lower die base 4 are clamped, the first positioning block 2a2 of the upper die base 2 gradually generates pressure on the top of the second positioning block 4b so that the second positioning block 4b compresses the spring 4c1 and enters the inner groove 4c. The first positioning block 2a2 positions the workpiece blank 5 to ensure the stable state of the workpiece blank 5.

[0056] Further, such as Figure 5 As shown:

[0057] Second limiting grooves 4c2 extending vertically upward from the bottom of the inner groove 4c are arranged on both sides of the inner wall of the inner groove 4c, and the length of the second limiting groove 4c2 is smaller than the length of the inner groove 4c; limiting blocks 4b1 matching the cross-sectional shape of the second limiting groove 4c2 are arranged on both sides of the bottom end of the second positioning block 4b, and the limiting block 4b1 is limitedly inserted in the second limiting groove 4c2.

[0058] In the present invention, a second limiting groove 4c2 is set in the inner groove 4c to cooperate with the limiting block 4b1 at the bottom of the second positioning block 4b to limit the position of the second positioning block 4b. Under normal conditions, the spring 4c1 applies an upward thrust to the second positioning block 4b so that the upper part of the limiting block 4b1 is in contact with the top of the second limiting groove 4c2 to prevent the second positioning block 4b from separating from the inner groove 4c.

[0059] Further, such as Figure 2 and Figure 4 As shown:

[0060] The base 1 is provided with vertically extending first slide rails 1d on both sides; the pressing plate 1a1 and the supporting plate 1b1 are inserted on both sides of the first slide rails 1d through first limiting grooves 1a2.

[0061] A plurality of guide rods 1b3 extending vertically downward are provided below the support plate 1b1, and the guide rods 1b3 are inserted into guide holes 1c2 provided on the fixed platform 1c.

[0062] A first slide rail 1d is arranged on both sides of the base 1, and both sides of the pressing plate 1a1 and the supporting plate 1b1 are slidably matched with the first slide rail 1d through the first limiting groove 1a2, ensuring that the upper hydraulic cylinder 1a and the lower hydraulic cylinder 1b drive the pressing plate 1a1 and the supporting plate 1b1 to move stably and smoothly, and the guide rod 1b3 arranged at the bottom of the lower hydraulic cylinder 1b is inserted into the guide hole 1c2 of the fixed platform 1c.

[0063] Further, such as Figure 3 , Fig.12 and Fig.13 As shown:

[0064] The unloading device 6 includes a plurality of clamping jaws 6a, which are arranged to move in the horizontal direction, and the clamping jaws 6a are used to grab the workpiece blank 5 ejected by the ejecting rod 1c1 for unloading;

[0065] The unloading device 6 also includes a mounting frame 6b, which is fixedly mounted on both sides of the outside of the base 1; a first linear drive device 6c is fixedly mounted on the mounting frame 6b, and the working end of the first linear drive device 6c is arranged to move in the horizontal direction. A slider 6c1 is fixedly mounted on the working end of the first linear drive device 6c, and the slider 6c1 is slidably matched with the second slide rail 6b1 on the mounting frame 6b, and the second slide rail 6b1 extends horizontally along the moving direction of the working end of the first linear drive device 6c; a horizontal connecting bracket 6d is connected to the second slide rail 6b1 on both sides of the base 1, and the clamping jaws 6a are installed on the connecting bracket 6d at equal intervals along the length direction of the connecting bracket 6d; clamping plates 6a1 are arranged on both sides of the working end of the clamping jaw 6a, and the clamping plates 6a1 are used to clamp the shaft sleeve 5a of the workpiece blank 5.

[0066] The mounting frame 6b is provided with a first linear drive device 6c on both sides of the base 1. The first linear drive device 6c can be a slide or a cylinder, etc. The first linear drive devices 6c on both sides move synchronously to drive the clamping jaws 6a to move in a horizontal direction perpendicular to the moving direction of the upper die base 2. The clamping jaws 6a can be pneumatic or electric clamping jaws. When the lower hydraulic cylinder 1b drives the lower die base 4 to move downward until the ejecting rod 1c1 contacts the bottom of the flange sleeve 5a, the first linear drive device 6c starts to move toward the lower die base 4. When the ejecting rod 1c1 lifts the flange from the axial hole 4a of the lower die base 4, the clamping plates 6a1 fixed on the clamping jaws 6a can be inserted into both sides of the sleeve 5a, and the clamping jaws 6a start to drive the clamping jaws 6a to move horizontally. Plate 6a1 clamps the sleeve 5a. When the flange is completely separated from the lower die base 4, the first linear drive device 6c starts to drive the clamping jaw 6a to reset and complete the unloading of the flange. After the first linear drive device 6c drives the clamping jaw 6a to reset, it should ensure that the clamping plate 6a1 of the clamping jaw 6a is completely separated from the moving range of the lower die base 4 and the support plate 1b1, so as to avoid affecting the upward movement of the support plate 1b1 and the lower die base 4. The clamping jaw 6a is fixedly mounted on the connecting bracket 6d. The two ends of the connecting bracket 6d are fixedly connected to the slider 6c1 on the working end of the first linear drive device 6c. The slider 6c1 slides with the second slide rail 6b1 on the mounting frame 6b to ensure the stability of the clamping jaw 6a when driving the flange to unload.

[0069] The present invention installs a collection box 6e on the mounting frame 6b to collect the processed flanges. After the clamp 6a drives the flange to move to the upper side of the collection box 6e, the clamp 6a starts to drive the clamp 6a1 to open and release the flange, and the flange falls into the collection box 6e. The staff only needs to collect the flanges in the collection box 6e after multiple processing, which saves manpower and improves efficiency.

[0070] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention.
