Description

Technical Field

[0001] This utility model relates to the field of stamping technology, specifically a stamping device for processing lifting arms. Background Technology

[0002] Stamping equipment is an industrial tool that uses mechanical or hydraulic force to form and process metal sheets. It mainly includes three categories: mechanical punch presses, hydraulic presses, and servo punch presses. Its core working principle is to apply pressure to the sheet metal using a die to complete processes such as punching, bending, and stretching. It is widely used in the automotive, electronics, and hardware industries.

[0003] Lifting booms typically employ a truss structure design, primarily composed of three basic components: the upper chord, the lower chord, and the web members. The web members are crucial components connecting the upper and lower chords, securely fixed to them with bolts. To achieve this bolted connection, precise bolt holes must be pre-machined at both ends of the web members using a stamping machine. During the stamping process, the operator must feed one end of the web member into a punching die for the punching operation. Once the hole at one end is punched, the operator must remove the web member from the die and then feed the other end into the die for the same punching operation. This process is not only tedious but also demands a high level of physical strength from the workers. Therefore, a stamping device for lifting boom processing is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a stamping device for processing lifting arms, so as to solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamping device for processing lifting arms, comprising a base, a punching die fixedly mounted on the base, a movable slide groove on the upper surface of the base, a feeding mechanism on the base, the feeding mechanism comprising a slider slidably mounted in the movable slide groove, a slide table fixedly mounted on the slider, a clamp slidably mounted on the slide table, hydraulic cylinders fixedly mounted on both sides of the slide table, the output ends of the hydraulic cylinders fixedly mounted on the clamps, a web rod between the clamps, and a unloading mechanism on the base.

[0006] Preferably, drive screws are rotatably mounted on both sides of the slider, a drive shaft is rotatably mounted inside the slider, and the upper end of the drive shaft is fixedly mounted on the slide table. A worm gear is fixedly mounted on the drive shaft, a worm is rotatably mounted on one side of the worm gear, and a motor is connected to one end of the worm. A discharge port is provided on the punching die, and a discharge groove is provided below the discharge port.

[0007] Preferably, a lead screw nut is fixedly installed on the slider, and the slider is connected to the drive lead screw through the lead screw nut.

[0008] Preferably, the slider is movably mounted on the equipment base via a movable groove, the slide table is rotatably mounted on the upper end of the slider via a drive shaft, and the worm is rotatably mounted on one side of the worm wheel via a motor, with the worm wheel and worm meshing together.

[0009] Preferably, the feeding mechanism includes a positioning seat fixedly installed on the side wall of the equipment base and a cylinder movably installed inside the equipment base. A movable shaft is rotatably installed on the positioning seat, a support rod is fixedly installed on the movable shaft, a crossbar is fixedly installed in the middle of the support rod, and a feeding slide is fixedly installed at the upper end of the support rod. The feeding slide is provided with a workpiece groove.

[0010] Preferably, the positioning seat has a movable hole, and the movable shaft is rotatably mounted on the positioning seat through the movable hole.

[0011] Preferably, the feeding slide is movably mounted on the upper end of the equipment base via a support rod, one end of the cylinder is rotatably mounted in the middle of the crossbar, and the other end of the cylinder is rotatably mounted inside the equipment base.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this application, after the web member is fixed to the slide table, the forward movement of the web member on the slide table is achieved by rotating the drive screw, thereby feeding one end of the web member into the punching die to perform the punching operation. After the punching operation at one end of the web member is completed, the slide table can be operated to reset. After the reset is completed, the worm gear is driven to rotate by the motor, which in turn causes the worm wheel to rotate. The rotation of the worm wheel drives the drive shaft to rotate, and the rotation of the drive shaft drives the web member on the slide table to rotate, so that the other end of the web member is aligned with the punching die. After alignment, the web member on the slide table is moved forward again by rotating the drive screw, feeding the other end of the web member into the punching die for punching, thereby realizing an automated feeding process.

[0014] 2. In this application, after the punching process is completed, the clamp can be released. Subsequently, by controlling the extension of the cylinder, the extension of the cylinder will drive the crossbar to move forward. The forward movement of the crossbar causes the unloading slide to rotate around the movable shaft as a fulcrum, thereby causing the unloading slide to tilt outward towards the outside of the equipment base. This action removes the web bar from the clamp, thereby realizing the automatic unloading function. Attached Figure Description

[0021] 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.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution for a stamping device for processing lifting arms, including a base 1, a punching die 3 fixedly installed on the base 1, a movable slide groove 5 on the upper surface of the base 1, a feeding mechanism 6 on the base 1, a discharging mechanism 7 on the base 1, a discharge port 301 on the punching die 3, and a discharge slide groove 2 below the discharge port 301. The feeding mechanism 6 can replace manual labor to achieve automatic feeding, and the discharging mechanism 7 can replace manual labor to achieve automatic unloading, reducing the labor intensity of workers.

[0023] like Figure 2 and Figure 4As shown, the feeding mechanism 6 includes a slider 603 slidably installed in the movable slide groove 5, a slide table 602 fixedly installed on the slider 603, a clamp 601 slidably installed on the slide table 602, hydraulic cylinders 604 fixedly installed on both sides of the slide table 602, the output end of the hydraulic cylinder 604 fixedly installed on the clamp 601, a web rod 4 is provided between the clamps 601, a drive screw 605 is rotatably installed on both sides of the slider 603, a drive shaft 608 is rotatably installed inside the slider 603, and the upper end of the drive shaft 608 is fixedly installed on the slide table 602, a worm gear 607 is fixedly installed on the drive shaft 608, a worm 606 is rotatably installed on one side of the worm gear 607, a motor 609 is connected to one end of the worm 606, a screw nut is fixedly installed on the slider 603, and the slider 603 is connected to the drive screw 605 through the screw nut.

[0024] Specifically, during the processing, the web member 4 is clamped and fixed on the slide table 602. Then, through the precise rotation of the drive screw 605, the slide table 602 moves the web member 4 forward. This action allows one end of the web member 4 to be smoothly fed into the punching die 3 for precise punching. After the punching operation at one end of the web member 4 is completed, the slide table 602 is reset to ensure that the web member 4 can be safely removed from the punching die 3. After reset, the motor 609 starts working, driving the worm gear 606 to rotate through its power output. The rotation of the worm gear 606 further drives the worm wheel 607, which rotates accordingly and transmits power to the drive shaft 608. The rotation of the drive shaft 608 causes the web member 4 on the slide table 602 to rotate, ensuring that the other end of the web member 4 is accurately aligned with the punching die 3. Once alignment is complete, the drive screw 605 takes effect again, pushing the slide table 602 and the web rod 4 forward, feeding the other end of the web rod 4 into the punching die 3 to complete the punching operation on the other end. The entire process is automated, greatly reducing the need for manual material feeding and improving production efficiency and processing accuracy.

[0025] like Figure 2 and Figure 5 As shown, the unloading mechanism 7 includes a positioning seat 704 fixedly installed on the side wall of the equipment base 1 and a cylinder 706 movably installed inside the equipment base 1. A movable shaft 707 is rotatably installed on the positioning seat 704, a support rod 703 is fixedly installed on the movable shaft 707, a crossbar 705 is fixedly installed in the middle of the support rod 703, an unloading slide bar 702 is fixedly installed at the upper end of the support rod 703, a workpiece groove 701 is provided on the unloading slide bar 702, and a movable hole is opened on the positioning seat 704. The movable shaft 707 is rotatably installed on the positioning seat 704 through the movable hole.

[0026] Specifically, after the punching operation is completed, the operator can proceed to the next step, namely, releasing the clamp 601. Once the clamp 601 is released, the extension action of the control cylinder 706 can be initiated. During the extension process, the cylinder 706 pushes the crossbar 705 forward. After the crossbar 705 moves forward, it will drive the unloading slide 702 to rotate around the movable shaft 707 as the fulcrum. As the unloading slide 702 rotates, it will tilt outwards towards the outside of the equipment base 1, thereby allowing the web bar 4 inside the clamp 601 to be transferred out. Through this series of mechanical actions, the automatic unloading function is realized, greatly improving production efficiency and ease of operation.

[0027] Working principle: When in use, first place the web rod 4 between the clamps 601. After the web rod 4 is placed between the clamps 601, the hydraulic cylinder 604 can be activated to move the clamps 601 forward and clamp the web rod 4 onto the slide table 602. After the web rod 4 is clamped onto the slide table 602, the rotation of the drive screw 605 can drive the web rod 4 on the slide table 602 to move forward, thereby sending one end of the web rod 4 into the punching die 3 for punching. After one end of the web rod 4 is punched, the slide table 602 can be reset. After the slide table 602 is reset, the motor 609 can drive the worm gear 606 to rotate. After the worm gear 606 rotates, it will drive the worm wheel 607 to rotate. After the worm wheel 607 rotates, it will drive the drive shaft 608 to rotate. After the drive shaft 608 rotates, it will drive the web rod 4 on the slide table 602 to rotate, so that the other end of the web rod 4 is aligned with the punching die 3. After the other end of the web rod 4 is aligned with the punching die 3, the rotation of the drive screw 605 can drive the web rod 4 on the slide table 602 to move forward again, sending the other end of the web rod 4 into the punching die 3 for punching, replacing the manual feeding operation. After punching is completed, clamp 601 can be released. After clamp 601 is released, cylinder 706 can be extended. After cylinder 706 extends, it will push crossbar 705 forward. After crossbar 705 moves forward, it will cause unloading slide 702 to rotate around movable shaft 707, thereby causing unloading slide 702 to tilt outward of equipment base 1, transferring the web bar 4 in clamp 601 out, realizing automatic unloading.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
