Description

Technical Field

[0001] The invention relates to the technical field of stamping production of street lamp shades, and in particular to a stamping device and a stamping method for producing street lamp shades. Background Art

[0002] Street lamp shade usually refers to the outer cover or protective cover of the street lamp. Its main function is to protect the bulb or light source inside the lamp, and to reasonably gather and scatter the light to provide a more effective lighting effect. It is usually made of plastic and metal. The plastic lampshade is made by injection molding, while the metal lampshade is made by stamping, which requires stamping equipment to complete.

[0003] Announcement No. CN113385606A discloses a multiple anti-pinch punching machine and its protection method, which include a frame, a control system and an automatic protection device. The front end of the frame is provided with a concave punching area, and the frame is provided with an operating area in front of the punching area. A button is provided on the left and right sides of the operating area, and the two buttons are respectively connected to the control system; the automatic protection device at least includes a bracket, a cylinder and a transparent protection plate. The bracket is fixedly mounted on the punch guide area, and a cylinder is respectively arranged at the left and right ends of the bracket. The pistons of the two cylinders pass through the bracket and are arranged downward. The top of the transparent protection plate is fixedly connected to the bottom end of the piston of the cylinder, and the two cylinders are respectively connected to the control system of the frame through wires.

[0004] The stamping machine is equipped with double buttons, automatic protection devices and infrared sensors to avoid safety accidents caused by workers or people around the stamping machine accidentally putting their hands into the stamping machine during the stamping process, thereby providing safety protection for the workers. The stamping machine is equipped with double buttons and automatic protection devices to prevent the operator's hands from entering the stamping area. At the same time, infrared sensors are used to control the shutdown of the stamping operation. If non-operating personnel are unaware, there is still a probability that they will put their hands into the stamping area.

[0021] The present invention also provides a protection method for a transformer maintenance platform, which is characterized by comprising the above-mentioned protection device for a transformer maintenance platform, and further comprising the following steps:

[0022] S1. Before stamping the lampshade, the lampshade metal plate needs to be pre-processed, including cutting and boring, to ensure the stamping of the lampshade metal plate, and then spray lubricating oil on the upper template and the lower template to reduce the friction between the lampshade metal plate and the upper template and the lower template, to ensure that the tension of the lampshade metal plate is uniform during stamping. After spraying the lubricating oil, the lampshade metal plate is placed on the lower template and corrected and aligned;

[0023] S2, then open the hydraulic rod, the driving end of the hydraulic rod drives the connector to move, the connector movement drives the limit plate to move, and then drives the upper template to move through the pillar, and then continues to move the upper template downward, the elastic telescopic rod continues to move downward to drive the rotating frame to move downward, until the upper template and the lampshade metal plate placed on the lower template are against each other, and at this time the rubber wheel just against the belt one;

[0024] Then turn on the motor, and the motor drive end rotates the belt, which will drive the roller to rotate through belt 2. The rotation of the roller drives belt roller 1 to rotate, and the sleeve roller rotates through belt 1. The rotation of belt 1 will drive the rubber wheel that resists it to rotate, and the rotation of the rubber wheel will drive the rotating rod to rotate. The rotation of the rotating rod will drive shaft 3 to rotate through transmission belt 5. The rotation of shaft 3 drives shaft 4 to rotate through transmission belt 2. Shaft 4 drives shaft 2 to rotate through transmission belt 4. At the same time, shaft 4 will also drive shaft 5 to rotate through transmission belt 3, thereby driving support block 1 and support block 2 to rotate, so that support block 1 and support block 2 rotate to vertically resist against the limit resist block. When support block 1 and support block 2 resist against the corresponding limit resist block, support block 1 and support block 2 cannot continue to rotate. At this time, the rubber wheel will slip between belt 1, and then the upper template continues to move downward, and the lampshade metal plate can be pressed into the mold cavity on the lower template for forming.

[0025] S3. Once the operator or non-operator's hand accidentally reaches between the upper template and the lower template, the upper template continues to move, and the movement of the upper template drives the movement of the lower template. The distance between the upper template and the lower template is greater than the thickness of the metal plate of the lampshade. Therefore, when the lower template moves, the rubber wheel does not abut against the belt one, and the support block one and the support block two do not rotate or do not rotate to a vertical angle. Therefore, the support block one and the support block two do not support the lower template. At this time, the lower template can still move downward freely, so as to perform the anti-pinch operation;

[0026] S4. The telescopic end of the electric push rod will drive the push plate to move, and the support beam will be driven to move through the push rod, thereby changing the height of the rotating shaft on the support beam. At this time, the height of belt one changes and increases. Therefore, when the upper template contacts the lampshade metal plate, the rubber wheel and belt one are against each other, and the compression of the conical spring is greater than the original compression. Support block one and support block two are rotated to the vertical position in advance, waiting for the lower template to move down, so as to stamp and form lampshade metal plates of different thicknesses.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] 1. When stamping the lampshade, the present invention provides a buffer path for the lower template by setting a gas spring, which can protect the upper template and the lower template, prevent the hydraulic rod from malfunctioning and causing excessive squeezing force between the upper template and the lower template, and reduce the probability of damage to the upper template and the lower template.

[0029] 2. When the lampshade is stamped, the present invention can lock the lower template by setting shaft one, shaft five, support block one and support block two to prevent the lower template from moving downward. At this time, relative displacement will occur between the lower template and the upper template, so that the lampshade metal plate is pressed into the mold cavity of the lower template for shaping. At the same time, by setting belt one, rubber wheel and rotating rod, support block one and support block two are driven to rotate. Since there is a certain travel spacing between the rubber wheel and belt one, the timing for support block one and support block two to start operating can be changed by setting the spacing. Once support block one and support block two miss the timing, they cannot support the lower template. Therefore, the lower template cannot be locked and can move downward freely. At this time, the hand clamped between the upper template and the lower template can be freely pulled out, so the hands of the operator and the non-operator are protected. Mechanical operation protection is adopted, the protection response is more timely, the failure rate is lower, the protection performance is higher, and the safety is higher.

[0030] 3. When stamping the lampshade, the present invention sets an electric push rod, a push plate and a push rod, and the electric push rod can be used to drive the push plate to move, and then the push rod can be used to drive the support beam to move, thereby changing the height of the belt one, thereby changing the stroke of the belt one and the rubber wheel, so that lampshade metal plates of different thicknesses can be stamped and formed.

[0031] In summary, the present invention uses mechanical operation to protect hands that are accidentally inserted between the upper template and the lower template. It still plays a protective role when the infrared sensor fails. The protection response is more timely, the failure rate is lower, and the safety is higher. At the same time, the upper template and the lower template can be buffered to avoid the hydraulic rod failure causing excessive pressure between the upper template and the lower template, causing damage to the upper template and the lower template.

DETAILED DESCRIPTION

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.

[0053] Example 1: Reference Figure 1-Figure 6 , a stamping device for producing street lamp shades, comprising a control cabinet 1, and a support frame 2 fixedly mounted above the control cabinet 1;

[0054] The stamping part is mounted on the support frame 2 and is used for stamping the lampshade. The stamping part includes a plurality of limit sliding posts 6 fixedly mounted on the support frame 2, a fixed plate 4 is fixedly mounted on the plurality of limit sliding posts 6, a limit plate 5 is slidably mounted on the plurality of limit sliding posts 6, an upper template 13 is fixedly mounted on the limit plate 5, and a driving mechanism is installed between the fixed plate 4 and the upper template 13;

[0055] The driving mechanism includes a hydraulic rod 3 fixedly mounted on a fixed plate 4, a connector 12 is fixedly mounted on the telescopic end of the hydraulic rod 3, the connector 12 is fixedly connected to the limit plate 5 by a locking clamp 11, and the upper template 13 is fixedly connected to the limit plate 5 by a plurality of pillars;

[0056] The driving end of the hydraulic rod 3 drives the connecting head 12 to move, and the movement of the connecting head 12 drives the limit plate 5 to move, thereby driving the upper template 13 to move through the support. The purpose of using the connecting head 12 is to change the displacement range of the upper template 13 within a fixed stroke, so as to be suitable for stamping lampshade metal plates of different thicknesses.

[0057] A plurality of circular holes are provided on the limit plate 5, and a limit sleeve matching the corresponding limit slide column 6 is fixedly installed in each circular hole; the movement of the limit plate 5 will drive the limit sleeve to slide on the limit slide column 6, which can effectively reduce the friction force and make the movement of the limit plate 5 smoother. At the same time, it can also reduce the load on the hydraulic rod 3 and extend the service life of the hydraulic rod 3.

[0058] A mounting plate 15 is fixedly mounted on the support frame 2, and a plurality of limit slide posts 9 are fixedly mounted on the mounting plate 15. A lower template 14 matching the upper template 13 is slidably mounted on the plurality of limit slide posts 9. A mold cavity is provided on the lower template 14, and a protrusion matching the mold cavity is provided on the upper template 13. During stamping, the protrusion extends into the mold cavity to stamp and form the metal plate of the lampshade.

[0059] Embodiment 2: This embodiment is different from the embodiment 1 in that: Figure 1-Figure 3 , Figure 7-Figure 18 , support part, the support part is installed on the support frame 2, and cooperates with the lower template 14 to support the lower template 14 and lock the lower template 14. The support part includes a support plate 17 fixedly installed on the mounting plate 15, and a support mechanism is installed between the support plate 17 and the lower template 14. A plurality of gas springs 18 are fixedly installed between the lower template 14 and the support plate 17. The gas spring 18 is an existing inflatable spring. The specific function description is not given here. It can be regarded as a spring, but it has higher stability and durability.

[0060] The support mechanism includes an axis 1 39 and an axis 5 rotatably mounted on the support plate 17, a plurality of support blocks 1 37 matched with the lower template 14 are fixedly mounted on the axis 1 39, a plurality of support blocks 2 52 matched with the lower template 14 are fixedly mounted on the axis 5, a linkage structure is installed between the axis 1 39 and the axis 5, and a plurality of limit blocks 40 matched with the corresponding support blocks 1 37 and support blocks 2 52 are fixedly mounted on the support plate 17;

[0061] The linkage structure includes shaft 2 42 and shaft 49 rotatably mounted on the mounting plate 15, a transmission belt 1 43 is commonly sleeved between shaft 2 42 and shaft 1 39, a transmission belt 3 50 is commonly sleeved between shaft 49 and shaft 5, a transmission belt 4 51 is commonly sleeved between shaft 2 42 and shaft 4 49, and a transmission structure is installed between the upper template 13 and shaft 4 49.

[0062] In a further embodiment, the transmission structure includes two connecting plates 33 fixedly mounted on the upper template 13, each of the two connecting plates 33 is fixedly mounted with an elastic telescopic rod 34, and one end of the two elastic telescopic rods 34 away from the connecting plates 33 is fixedly mounted with a rotating frame 36, a rotating rod 35 is rotatably mounted on the rotating frame 36, and a limit block matching the rotating frame 36 is fixedly mounted on the support plate 17;

[0063] The function of the limit block is to limit the rotating frame 36. When the rotating frame 36 moves up a certain distance, the rotating frame 36 abuts against the limit block. At this time, the rotating frame 36 stops moving, while the connecting plate 33 at the other end of the elastic telescopic rod 34 continues to move. In this way, the rotating frame 36 can be kept moving within a certain range, and there is no need to open a through hole on the lower template 14 for the movement of the rotating frame 36.

[0064] An oblique frame 44 is fixedly mounted on the support plate 17, a slider 45 is slidably mounted on the oblique frame 44, a return spring 46 is fixedly mounted between the slider 45 and the oblique frame 44, a shaft 3 47 is rotatably mounted on the slider 45, a transmission belt 2 48 is commonly sleeved between the shaft 3 47 and the shaft 4 49, a transmission belt 5 is commonly sleeved between the rotating rod 35 and the shaft 3 47, and a driving component is installed between the mounting plate 15 and the rotating rod 35;

[0065] The length of the elastic telescopic rod 34 is smaller than the single displacement of the upper template 13, so that it can be ensured that before the upper template 13 contacts the metal plate of the lampshade, the elastic telescopic rod 34 can drive the rotating frame 36 to move. The elastic telescopic rod 34 is an existing telescopic rod that can automatically reset, and a spring is arranged inside it (a conical spring is arranged inside the elastic telescopic rod 34, and when the upper template 13 moves upward, the conical spring is in a stretched state. When the elastic telescopic rod 34 is in a normal state, the rubber wheel 38 does not contact the belt 1 21. When the rubber wheel 38 contacts the belt 1 21, the cylindrical spring will be compressed under the pressure force, and the conical spring is in a compressed state at this time);

[0066] When the connecting plate 33 moves downward, it drives the elastic telescopic rod 34 to reset. When the elastic telescopic rod 34 is reset to the normal state, the elastic telescopic rod 34 continues to move downward to drive the rotating frame 36 to move downward. When the rotating frame 36 moves downward, the slider 45 will be driven to move to the bottom of the inclined frame 44 under the action of the reset spring 46, keeping the transmission belt five taut. The movement of the slider 45 will also tighten the transmission belt two 48. At this time, the rotation of the rotating rod 35 will drive the shaft four 49 to rotate through the transmission belt two 48, and the shaft four 49 will drive the shaft two 42 to rotate through the transmission belt four 51. At the same time, the shaft four 49 will also drive the shaft five to rotate through the transmission belt three 50, thereby driving the support block one 37 and the support block two 52 to rotate, so that the support block one 37 and the support block two 52 are rotated to vertically abut against the limit stop block 40. When the support block one 37 and the support block two 52 abut against the corresponding limit stop block 40, the support block one 37 and the support block two 52 cannot continue to rotate. At this time, the rubber wheel 38 will slip between the belt one 21.

[0067] A plurality of arc-shaped support rods 41 matching with the corresponding support blocks 1 37 and 2 52 are fixedly mounted on the support plate 17. Arc-shaped through grooves matching with the corresponding support arc-shaped rods 41 are provided on the support blocks 1 37 and 2 52. When the support blocks 1 37 and 2 52 are rotated to vertical, the arc-shaped support rods 41 will pass through the arc-shaped through grooves to support the support blocks 1 37 and 2 52, thereby preventing the shaft 1 39 and the shaft 5 from being directly subjected to force, protecting the shaft 1 39 and the shaft 5, and extending the service life of the shaft 1 39 and the shaft 5.

[0068] The driving component includes a push plate 28 fixedly mounted on the bottom of the mounting plate 15, an electric push rod 29 fixedly mounted on the bottom of the mounting plate 15, a driving end of the electric push rod 29 is fixedly connected to the push plate 28, a plurality of push rods 20 are fixedly mounted on the push plate 28, a support beam 16 is fixedly mounted on two groups of matched push rods 20, a roller is rotatably mounted on the support beam 16, and a rotating shaft 23 is slidably mounted on the support beam 16, and an adjustment component is installed between the support beam 16 and the rotating shaft 23;

[0069] The telescopic end of the electric push rod 29 drives the push plate 28 to move, and drives the support beam 16 to move through the push rod 20, thereby changing the height of the rotating shaft 23 on the support beam 16.

[0070] The adjustment assembly includes a fixed block 26 fixedly mounted on the support beam 16, a nut 25 fixedly mounted on the fixed block 26, a screw rod 24 rotatably mounted on the nut 25, a connecting rod 27 rotatably mounted on the screw 24, and the connecting rod 27 is fixedly connected to the rotating shaft 23;

[0071] Rotating the screw 24 will drive the connecting rod 27 to move under the action of the nut 25, thereby driving the rotating shaft 23 to move. The movement of the rotating shaft 23 drives the sleeve roller 19 to move, thereby changing the distance between the sleeve roller 19 and the rotating roller, so as to adjust the tightness of the belt 21 and ensure that the belt 21 maintains a certain tension so that the generated friction force is stable and effective.

[0072] Reference Figure 9-13 A sleeve roller 19 is rotatably mounted on the rotating shaft 23, two belt rollers 31 are fixedly mounted on the sleeve roller 19 and the rotating roller, a belt 21 is sleeved between the two matching belt rollers 31, two pressing plates 22 matching the corresponding belts 21 are fixedly mounted on the support beam 16, a rubber wheel 38 matching the corresponding belt 21 is fixedly mounted on both ends of the rotating rod 35, and a driving component is installed between the support beam 16 and the rotating roller;

[0073] The rotation of the roller drives the belt roller 31 to rotate, and the sleeve roller 19 is driven to rotate through the belt 21. During the rotation of the belt 21, when the rubber wheel 38 moves down to abut against the belt 21, the rubber wheel 38 and the belt 21 will be pressed tightly under the action of the pressing plate 22. At this time, the rotation of the belt 21 will drive the rubber wheel 38 to rotate (driven by friction. Since the clamping force of the clamp is a hard clamp, once the clamp is clamped, the clamping force of the clamp is greater than the friction, which will cause the rubber wheel 38 to slip on the belt 21). The rotation of the rubber wheel 38 drives the rotating rod 35 to rotate.

[0074] Reference Fig.13 The driving assembly includes a motor 10 fixedly mounted on a support beam 16, a belt 2 30 is provided between the driving end of the motor 10 and the rotating roller, and a pressing roller 32 matched with the belt 2 30 is rotatably mounted on the support beam 16;

[0075] The driving end of the motor 10 rotates the belt, which drives the roller to rotate through the belt 2 30. The function of the pressure roller 32 is to press and tighten the belt 2 30 to ensure that the belt 2 30 can drive the roller to rotate and reduce the probability of slipping.

[0076] When the rotating frame 36 moves to the moving degree (the rubber wheel 38 is in close contact with the belt 1 21), the upper template 13 is just moved to be in contact with the lampshade metal plate on the lower template 14, and then the upper template 13 is continued to be moved. At this time, under the pressure force, the lower template 14 is also driven to move together. At this time, the lower template 14 and the support block 1 37 and the support block 2 52 operate simultaneously. When the lower template 14 moves to the top of the support block 1 37 and the support block 2 52, the support block 1 37 and the support block 2 52 are just in a vertical state to support the lower template 14;

[0077] If the operator's hand is placed on the lampshade metal plate, the upper template 13 moves to drive the lower template 14 to move. The distance between the upper template 13 and the lower template 14 is greater than the thickness of the lampshade metal plate. Therefore, when the lower template 14 moves, the rubber wheel 38 does not abut against the belt 1 21, and the support block 1 37 and the support block 2 52 do not rotate or do not rotate to a vertical angle. Therefore, the support block 1 37 and the support block 2 52 do not support the lower template 14. At this time, the lower template 14 can still move downward freely to perform anti-pinch operation. The height of the belt 1 21 can be changed to change the height of the upper template 13 when the belt 1 21 abuts against the rubber wheel 38, so as to stamp and form lampshade metal plates of different thicknesses.

[0078] A gasket 7 is fixedly mounted on the support frame 2, a backing plate 8 is fixedly mounted on the gasket 7, and the mounting plate 15 is fixedly mounted on the backing plate 8. The gasket 7 is used to expand the contact area with the control cabinet 1 and reduce the probability of collapse of the top of the control cabinet 1. The function of the backing plate 8 is to increase the strength of the gasket 7 and improve the stability during operation. The motor 10, the hydraulic rod 3 and the electric push rod 29 are all controlled by the controller in the control cabinet 1. It is an existing electric control system and will not be elaborated here.

[0079] The specific operation steps of this device are as follows:

[0080] S1. Before stamping the lampshade, the lampshade metal plate needs to be pre-processed, including cutting and boring, to ensure the stamping of the lampshade metal plate, and then spray lubricating oil on the upper template 13 and the lower template 14 to reduce the friction between the lampshade metal plate and the upper template 13 and the lower template 14 to ensure uniform tension during stamping of the lampshade metal plate. After spraying the lubricating oil, place the lampshade metal plate on the lower template 14 and align it.

[0081] S2, then open the hydraulic rod 3, the driving end of the hydraulic rod 3 drives the connecting head 12 to move, the movement of the connecting head 12 drives the limit plate 5 to move, and then drives the upper template 13 to move through the pillar (the upper template 13 will drive the connecting plate 33 to move downward, and the connecting plate 33 will drive the elastic telescopic rod 34 to reset when moving downward, and before the upper template 13 contacts the lampshade metal plate, the elastic telescopic rod 34 will reset to a normal state), then continue to move the upper template 13 downward, and the elastic telescopic rod 34 will continue to move downward to drive the rotating frame 36 to move downward until the upper template 13 abuts against the lampshade metal plate placed on the lower template 14, and at this time the rubber wheel 38 just abuts against the belt 1 21;

[0082] Then, the motor 10 is turned on, and the driving end of the motor 10 rotates the belt, which drives the roller to rotate through the belt 2 30, and the rotation of the roller drives the belt roller 1 31 to rotate, and the sleeve roller 19 is driven to rotate through the belt 1 21. The rotation of the belt 1 21 drives the rubber wheel 38 to rotate, and the rotation of the rubber wheel 38 drives the rotating rod 35 to rotate. The rotation of the rotating rod 35 drives the shaft 3 47 to rotate through the transmission belt 5, and the rotation of the shaft 3 47 drives the shaft 4 49 to rotate through the transmission belt 2 48, and the shaft 49 drives the shaft 2 42 to rotate through the transmission belt 4 51. Four 49 will also drive shaft five to rotate through transmission belt three 50, thereby driving support block one 37 and support block two 52 to rotate, so that support block one 37 and support block two 52 rotate to vertically abut against limit stop block 40. When support block one 37 and support block two 52 abut against corresponding limit stop block 40, support block one 37 and support block two 52 cannot continue to rotate. At this time, rubber wheel 38 will slip between belt one 21, and then upper template 13 continues to move downward, so that the lampshade metal plate can be pressed into the mold cavity on lower template 14 for forming.

[0083] S3. Once the operator or non-operator's hand accidentally extends into the space between the upper template 13 and the lower template 14, the upper template 13 continues to move, and the movement of the upper template 13 drives the lower template 14 to move. The distance between the upper template 13 and the lower template 14 is greater than the thickness of the lampshade metal plate. Therefore, when the lower template 14 moves, the rubber wheel 38 does not abut against the belt 1 21, and the support block 1 37 and the support block 2 52 do not rotate or rotate to a vertical angle. Therefore, the support block 1 37 and the support block 2 52 do not support the lower template 14. At this time, the lower template 14 can still move downward freely to perform the anti-pinch operation.

[0084] S4, the telescopic end of the electric push rod 29 will drive the push plate 28 to move, and drive the support beam 16 to move through the push rod 20, thereby changing the height of the rotating shaft 23 on the support beam 16 (increasing). At this time, the height of the belt 1 21 changes (increasing). Therefore, when the upper template 13 contacts the lampshade metal plate, the rubber wheel 38 and the belt 1 21 are at odds with each other, and the compression of the conical spring is greater than the original compression, and the support block 1 37 and the support block 2 52 are rotated to the vertical position in advance, waiting for the lower template 14 to move down, so as to stamp and form the lampshade metal plates of different thicknesses.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

4. A stamping method for producing street lamp shades, characterized in that: The stamping device for producing street lamp shades according to any one of claims 1 to 3 further comprises the following steps: S1. Before stamping the lampshade, the lampshade metal plate needs to be pre-processed, including cutting and boring, to ensure that the lampshade metal plate is stamped and formed, and then lubricating oil is sprayed on the upper template (13) and the lower template (14) to reduce the friction between the lampshade metal plate and the upper template (13) and the lower template (14), to ensure that the tension of the lampshade metal plate is uniform during stamping. After spraying the lubricating oil, the lampshade metal plate is placed on the lower template (14) and corrected and aligned; S2, then the hydraulic rod (3) is turned on, and the driving end of the hydraulic rod (3) drives the connecting head (12) to move, and the movement of the connecting head (12) drives the limit plate (5) to move, thereby driving the upper template (13) to move through the pillar, and then the upper template (13) continues to move downward, and the elastic telescopic rod (34) continues to move downward to drive the rotating frame (36) to move downward until the upper template (13) and the lampshade metal plate placed on the lower template (14) are in contact, and at this time, the rubber wheel (38) just contacts the belt 1 (21); Then, the motor (10) is turned on. The driving end of the motor (10) rotates the belt, which drives the roller to rotate through the belt 2 (30). The rotation of the roller drives the belt roller 1 (31) to rotate, which drives the sleeve roller (19) to rotate through the belt 1 (21). The rotation of the belt 1 (21) drives the rubber wheel (38) that contacts it to rotate. The rotation of the rubber wheel (38) drives the rotating rod (35) to rotate. The rotation of the rotating rod (35) drives the shaft 3 (47) to rotate through the transmission belt 5. The shaft 3 (47) rotates through the transmission belt 2 (48) to drive the shaft 4 (49). The shaft 4 (49) drives the shaft 2 (42) to rotate through the transmission belt 4 (51). When the shaft 4 (49) drives the shaft 5 to rotate through the transmission belt 3 (50), the support block 1 (37) and the support block 2 (52) are driven to rotate, so that the support block 1 (37) and the support block 2 (52) are rotated to be vertical and abut against the limit stop block (40). When the support block 1 (37) and the support block 2 (52) abut against the corresponding limit stop block (40), the support block 1 (37) and the support block 2 (52) cannot continue to rotate. At this time, the rubber wheel (38) and the belt 1 (21) slip, and then the upper template (13) continues to move downward, so that the lampshade metal plate can be pressed into the mold cavity on the lower template (14) for molding; S3. Once the operator or non-operator's hand accidentally reaches between the upper template (13) and the lower template (14), the upper template (13) continues to move, and the movement of the upper template (13) drives the lower template (14) to move. The distance between the upper template (13) and the lower template (14) is greater than the thickness of the metal plate of the lampshade. Therefore, when the lower template (14) moves, the rubber wheel (38) does not abut against the belt 1 (21), and the support block 1 (37) and the support block 2 (52) do not rotate or rotate to a vertical angle. Therefore, the support block 1 (37) and the support block 2 (52) do not support the lower template (14). At this time, the lower template (14) can still move downward freely, thereby performing an anti-pinch operation; S4, the telescopic end of the electric push rod (29) drives the push plate (28) to move, and drives the support beam (16) to move through the push rod (20), thereby changing the height of the rotating shaft (23) on the support beam (16). At this time, the height of the belt 1 (21) changes. Therefore, when the upper template (13) contacts the lampshade metal plate, the rubber wheel (38) and the belt 1 (21) are at odds with each other, and the compression amount of the conical spring is greater than the original compression amount. The support block 1 (37) and the support block 2 (52) are rotated to the vertical position in advance, waiting for the lower template (14) to move downward, so as to perform stamping and forming on the lampshade metal plates of different thicknesses.
