Description

Technical Field

[0001] This utility model relates to the field of metal sheet punching technology, specifically to a metal sheet punching processing device. Background Technology

[0002] In modern industrial production, sheet metal punching is a fundamental and crucial manufacturing process. To ensure punching accuracy and prevent sheet displacement, reliable clamping and securing of the sheet metal is an essential step. However, most commercially available sheet metal punching devices use a motor-driven gear and lead screw to move clamping blocks, which presents significant drawbacks in practical applications. For example, the lead screw and gear are typically exposed to the processing environment, and the sheet metal punching process generates a large amount of debris. This debris easily falls onto the surfaces of the lead screw and gear. Once debris enters, it increases friction between the lead screw and nut, and between gears, leading to problems such as transmission jamming and accelerated wear, severely affecting the reliability and stability of the transmission.

[0003] As disclosed in the prior art, Chinese utility model publication CN215786072U discloses a metal sheet punching device. This utility model includes a worktable with a base fixedly connected to its upper end; and two sets of clamping mechanisms. Each clamping mechanism includes a lead screw, a nut, two support blocks, two bevel gears, and a limiting component. The two support blocks are fixedly connected to the upper end of the base. The two ends of the lead screw movably pass through the two ends of the two support blocks and extend outward. In the above structure, since there is no protection for the lead screw, gears, etc., in actual use, debris will fall directly between the lead screw and the nut, and between the gears. That is, the aforementioned debris can cause transmission jamming and accelerated wear between the lead screw and the nut, and between the gears. Therefore, we need to propose a metal sheet punching processing device. Utility Model Content

[0004] The purpose of this invention is to provide a metal sheet punching processing device to solve the problem mentioned in the background art that debris falls on the surface of the lead screw and gears, resulting in increased friction between the lead screw and nut and between gears, which in turn leads to transmission jamming and accelerated wear.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A metal sheet punching processing device includes a support frame. A clamping mechanism is provided on the side of the support frame. The clamping mechanism includes a mounting frame, a movable seat, a clamping plate, a lead screw, a driven gear, a rotating rod, and a drive gear. The mounting frame is fixedly connected to the side of the support frame. The lead screw is movably installed inside the mounting frame. The driven gear is fixedly connected to the lead screw.

[0007] Preferably, one end of another set of corrugated pipes is fixedly installed on the other side of the movable seat, and the other end of the corrugated pipes is fixedly installed on the side of the mounting bracket.

[0008] Preferably, the clamping mechanism further includes a geared motor, which is fixedly installed in the mounting frame, and the output shaft of the geared motor is fixedly installed on the output shaft of the rotating rod through a coupling.

[0009] Preferably, the mounting frame has multiple sets of guide rods fixedly connected in a ring array inside, the lead screw is located at the center of the multiple sets of guide rods, the movable seat is slidably mounted on the guide rods, and the corrugated tube is sleeved on the guide rods.

[0010] Preferably, the bracket has an internal placement part for placing metal sheets, and a stop block for blocking waste material during metal sheet punching is fixedly installed on the top of the placement part. The top of the stop block is horizontally arranged with the bottom of the clamping plate.

[0011] Preferably, a hydraulic cylinder is fixedly installed on the top of the bracket, a lifting frame is fixedly installed on the telescopic end of the hydraulic cylinder, and multiple sets of punching heads for punching metal sheets are fixedly installed on the bottom of the lifting frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a bellows and mounting bracket structure to house the lead screw, drive gear, and driven gear within the mounting bracket. This keeps the drive gear and driven gear away from the support, significantly reducing the probability of debris falling onto their surfaces. Simultaneously, the mounting bracket forms a physical barrier, protecting the gears from debris intrusion. The bellows tightly encases the lead screw, effectively preventing debris adhesion and accumulation in the threaded gap, maintaining the smoothness of the lead screw transmission, and reducing friction between the lead screw and the moving seat caused by debris. By protecting the lead screw, moving seat, drive gear, and driven gear, it prevents transmission jamming and excessive wear, extends the service life of components, reduces maintenance costs and downtime, and decreases maintenance frequency and component replacement costs.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: A metal sheet punching processing device includes a bracket 1. A clamping mechanism 8 is provided on the side of the bracket 1. The clamping mechanism 8 includes a mounting frame 801, a movable seat 802, a clamping plate 803, a lead screw 804, a driven gear 805, a rotating rod 807, and a drive gear 808. The mounting frame 801 is fixedly connected to the side of the bracket 1. The lead screw 804 is movably installed inside the mounting frame 801. The driven gear 805 is fixedly connected to the lead screw 804. The rotating rod 807 is movably installed inside the mounting frame 801. The drive gear 808 is fixedly connected to the rotating rod 807. The driven gear 805 meshes with the drive gear 808. The movable seat 802 is threaded onto the lead screw 804, and the clamping plate 803 is fixedly installed on the side of the movable seat 802; Two sets of bellows 10 for protection are fitted on the lead screw 804.

[0019] In an optional embodiment: such as Figures 2 to 3 As shown, one end of a set of bellows 10 is fixedly installed on the side of the movable seat 802, and the other end of the bellows 10 is fixedly installed on the side of the bracket 1. One end of another set of corrugated pipes 10 is fixedly installed on the other side of the movable seat 802, and the other end of the corrugated pipes 10 is fixedly installed on the side of the mounting bracket 801.

[0020] It should be noted that, through the setting of the bellows 10, when the geared motor 806, together with the rotating rod 807, the drive gear 808 and the driven gear 805 drive the lead screw 804 to move the moving seat 802, the bellows 10 can expand and contract with it, always covering the surface of the lead screw 804, preventing dust, debris, oil and other debris from falling directly onto the lead screw 804, thereby avoiding the accumulation of debris from affecting the transmission accuracy and service life of the lead screw 804.

[0021] In an optional embodiment: such as Figures 2 to 3 As shown, the clamping mechanism 8 also includes a geared motor 806, which is fixedly installed in the mounting bracket 801. The output shaft of the geared motor 806 is fixedly installed on the output shaft of the rotating rod 807 through a coupling.

[0022] It should be noted that the geared motor 806 can drive the rotating rod 807 and the drive gear 808 to rotate, so that the drive gear 808 can drive the lead screw 804 to rotate through the driven gear 805. The geared motor 806 is set to have a brake motor. When the geared motor 806 is de-energized, the brake motor can brake instantly to prevent the output shaft from continuing to rotate due to inertia. This effectively prevents the rotating rod 807, the drive gear 808 and the lead screw 804 from rotating unexpectedly, and prevents the clamping plate 803 from shifting in the non-working state, thus affecting the clamping effect on the metal plate.

[0023] In an optional embodiment: such as Figure 4 As shown, the mounting bracket 801 has multiple sets of guide rods 9 fixedly connected in a ring array inside. The lead screw 804 is located at the center of the multiple sets of guide rods 9. The movable seat 802 is slidably mounted on the guide rods 9. The bellows 10 is sleeved on the guide rods 9. Two sets of second guide rails 18 are symmetrically fixedly installed on the side of the bracket 1. A second slider 19 is slidably installed on the top of each set of second guide rails 18. The second slider 19 is fixedly installed on the side of the clamping plate 803.

[0024] It should be noted that the guide rod 9 serves to support and guide the movable seat 802, enabling the movable seat 802 to move horizontally. In addition, the guide rod 9 also supports the bellows 10, preventing the movable seat 802 from tilting and contacting the lead screw 804 when the bellows 10 expands and contracts, thus preventing wear on the movable seat 802. The second slider 19 cooperates with the second guide rail 18 to support and guide the clamping plate 803, so that the clamping plate 803 can stably clamp and fix the metal plate after horizontal movement.

[0025] In an optional embodiment: such as Figure 1 As shown, the bracket 1 has a placement part 3 for placing metal plates inside. A stop block 17 for blocking waste material when punching metal plates is fixedly installed on the top of the placement part 3. The top of the stop block 17 is horizontally set with the bottom of the clamping plate 803.

[0026] It should be noted that by setting the stop 17, when the metal sheet is removed after punching, the waste chips that fall on the top of the metal sheet due to punching can be blocked by the stop 17 and collected on the placement part 3, which can reduce the amount of waste chips scattered on the outside of the bracket 1 and facilitate subsequent cleaning of waste chips.

[0027] In an optional embodiment: such as Figure 1 and Figure 2 As shown, a hydraulic cylinder 2 is fixedly installed on the top of the bracket 1, a lifting frame 4 is fixedly installed on the telescopic end of the hydraulic cylinder 2, and multiple sets of punching heads 5 for punching metal sheets are fixedly installed on the bottom of the lifting frame 4. The bracket 1 has two sets of first guide rails 7 fixedly installed symmetrically inside, and the lifting frame 4 has first sliders 6 fixedly installed on both sides. The first sliders 6 are slidably installed on the first guide rails 7.

[0028] It should be noted that the first slider 6 cooperates with the first guide rail 7 to guide the lifting frame 4, enabling the lifting frame 4 to move vertically up and down stably.

[0029] In an optional embodiment: such as Figure 2As shown, the bracket 1 has multiple sets of insertion holes 14 corresponding to the punching head 5 on the placement part 3. The bracket 1 has an inclined groove 15 for discharging the waste generated after the punching head 5 punches the metal sheet. The bracket 1 has a collection box 16 for collecting waste installed on the side.

[0030] It should be noted that the waste generated after punching the metal sheet can fall directly into the inclined groove 15 through the insertion hole 14, and the waste falling into the inclined groove 15 can be collected in the collection box 16.

[0031] In an optional embodiment: such as Figure 3 As shown, the clamping plate 803 has an clearance hole 13 inside, and a membrane pressure sensor 11 is fixedly installed on the clamping plate 803. A pressure plate 12 is fixedly installed on the detection end of the membrane pressure sensor 11, and the pressure plate 12 is located in the clearance hole 13.

[0032] It should be noted that by using the diaphragm pressure sensor 11 in conjunction with the pressure plate 12, the force required to clamp the metal sheet can be detected, preventing excessive clamping of the metal sheet. A controller is installed on the side of the bracket 1. The hydraulic cylinder 2, the geared motor 806 and the diaphragm pressure sensor 11 are all electrically connected to the controller. The controller can control the hydraulic cylinder 2 and the geared motor 806.

[0033] The usage process of this utility model is as follows: Place the metal sheet to be punched on the top of the placement part 3, with the top of the metal sheet higher than the stop block 17. Start the reduction motor 806. The output shaft of the reduction motor 806 drives the rotating rod 807 to drive the drive gear 808 to rotate. The drive gear 808 drives the driven gear 805 to rotate. The driven gear 805 drives the lead screw 804 to rotate. The lead screw 804 drives the moving seat 802 and the clamping plate 803 to move, so that the clamping plate 803 presses the metal sheet against the placement part 3. When the metal sheet is pressed and fixed, the pressure plate 12 also presses against the side of the metal sheet. When the pressure plate 12 is pressed against the side of the metal plate, the force of the pressure plate 12 pressing against the side of the metal plate will be transmitted to the membrane pressure sensor 11. The membrane pressure sensor 11 detects the force of clamping the metal plate. The parameters detected by the membrane pressure sensor 11 are converted into electrical signals and transmitted to the controller. The controller compares the detected value with the pre-set value for pressing the metal plate. When the value reaches the value for pressing the metal plate, the reduction motor 806 stops working. When hydraulic cylinder 2 is activated, its telescopic end pushes the lifting frame 4, enabling the lifting frame 4 to push the punch head 5 close to the metal sheet and punch holes in it. The corrugated pipe 10 protects the waste generated after the holes in the metal sheet from falling. The mounting bracket 801 also protects the waste generated after the holes in the metal sheet, greatly reducing the probability of debris falling onto the surfaces of the drive gear 808 and the driven gear 805, thus protecting the gears from debris. In addition, the waste and debris generated after the punch head 5 punches the metal sheet can fall into the inclined groove 15 through the insertion hole 14, allowing the waste and debris to fall into the collection box 16 along the inclined groove 15 for collection.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
