Abstract
Description
Technical Field
[0001] This invention relates to the field of stamping processing technology, specifically to a stamping processing equipment for the base plate of a robotic arm. Background Technology
[0002] A stamping machine is a mechanical device used for stamping and forming metal sheets. It deforms the metal sheet through pressure and dies to obtain the desired shape and size.
[0003] To ensure the stability of the robotic arm, the bottom of the robotic arm is usually connected to the base plate by circular welding. However, during the punching process of the base plate to be welded, because the end face of the metal sheet is a continuous body, the unpunched area at the punched edge is easily subjected to a large traction force during the punching process, causing the punched edge to bend and deform, resulting in insufficient integrity of the finished workpiece. Moreover, because the hardness distribution of the metal material to be processed cannot be completely uniform, if the punching parameters cannot be precisely matched, it will cause breakage marks on the punched section, resulting in insufficient integrity of the processed base plate.
[0004] Therefore, it is necessary to provide a stamping equipment for the base plate of a robotic arm to solve the problems mentioned in the background art. Summary of the Invention
[0005] To achieve the above objectives, the present invention provides the following technical solution: a stamping equipment for a robotic arm base plate, comprising:
[0006] Base;
[0007] A movable feeding mechanism is movably disposed at the center of the upper end face of the base, and the movable feeding mechanism is driven by a hydraulic cylinder disposed on one side of the base;
[0008] The gantry frame is fixed to the upper surface of the base and located around the moving feeding mechanism;
[0009] The stamping mechanism is fixedly installed on the top of the gantry frame; and
[0010] The pre-compression mechanism is installed on the gantry frame.
[0011] Furthermore, preferably, the upper end of the moving feeding mechanism is equipped with a lower mold, and the lower end of the stamping mechanism is equipped with an upper mold.
[0012] Furthermore, preferably, the pre-compression mechanism includes:
[0013] A movable frame is symmetrically and movably arranged on both sides of the gantry frame, and the movement of the movable frame is controlled by a drive mounted on the gantry frame;
[0014] Opening and closing adjusters are respectively fixed on the two movable frames; and
[0015] A rotary cutting component is located at the output end of the opening / closing regulator.
[0016] Furthermore, preferably, the rotary cutting assembly includes:
[0017] An arc-shaped base is fixed to the output end of the opening and closing regulator, and a semi-toothed ring is rotatably provided on the outer wall of the arc-shaped base;
[0018] A motor housing, fixed to the arc-shaped base, contains a servo motor; and
[0019] A gear is disposed at the output end of the servo motor, and the gear meshes with the half-tooth ring.
[0020] Furthermore, as a preferred embodiment, a rotary cutter is fixed to the bottom of the semi-toothed ring, and the rotary cutter is used to cut the upper surface of the robot arm base plate.
[0021] Furthermore, preferably, a speed sensor is also provided on the arc-shaped base. The speed sensor is used to monitor the rotation speed of the rotary cutting blade, and is electrically connected to the stamping mechanism. Compared with the prior art, the beneficial effects of the present invention are:
[0022] In this invention, the dividing points after the rotary cutter cuts transform the stamping edge of the material plate to be stamped from one continuous body into two independent continuous bodies. Therefore, the unprocessed area will not be pulled by the material in the processing area, thereby reducing the deformation of the stamping edge during the stamping process and improving the integrity of the base plate.
[0023] In this invention, the change in the rotation speed of the rotary cutter reflects the hardness distribution of the stamping edge material, thereby providing specific hardness data for the stamping mechanism. This allows the stamping mechanism to adjust its own stamping parameters to achieve optimal values, ensuring that the stamping parameters match the hardness of the material to be stamped. This reduces the number and area of fracture marks generated on the stamping cross-section during the stamping process, and improves the integrity of the base plate. Attached Figure Description

Detailed Implementation
[0030] Please see Figure 1-5 In this embodiment, a robotic arm base plate stamping processing equipment includes:
[0031] Base 1;
[0032] The movable feeding mechanism 2 is movably disposed at the center of the upper end face of the base 1, and the movable feeding mechanism 2 is driven by a hydraulic cylinder 3 disposed on one side of the base 1.
[0033] The gantry frame 4 is fixed to the upper surface of the base 1 and located around the mobile feeding mechanism 2;
[0034] The stamping mechanism 5 is fixedly installed on the top of the gantry frame 4; and
[0035] The pre-compression mechanism 6 is installed on the gantry frame 4.
[0036] In a preferred embodiment, a lower mold 21 is installed on the upper end of the moving feeding mechanism 2, and an upper mold 51 is installed on the lower end of the stamping mechanism 5.
[0037] Please refer to [link / reference needed] for further explanation. Figure 1 The stamping mechanism 5 carries the upper mold 51 to punch holes in the material plate on the lower mold 21, so that the material plate to be processed forms the required robot arm base plate. The pre-pressing mechanism 6 can cut the material plate to be processed before stamping, thereby improving the integrity of the material plate and thus improving the stamping efficiency.
[0038] In a preferred embodiment, the pre-compression mechanism 6 includes:
[0039] The movable frame 61 is symmetrically and movably arranged on both sides of the gantry frame 4, and the movable frame 61 is controlled to move by a drive provided on the gantry frame 4;
[0040] The opening and closing adjusters 62 are respectively fixed on the two movable frames 61; and
[0041] The rotary cutting component 63 is disposed at the output end of the opening and closing regulator 62.
[0042] Please note that you should refer to [link / reference]. Figure 2 The two rotary cutting components 63 can form an annular body under the driving action of the opening and closing regulator 62. In this shape state, the moving frame 61 moves down and performs micro-cutting on the material plate to be processed.
[0043] In a preferred embodiment, the rotary cutting assembly 63 includes:
[0044] An arc-shaped base 631 is fixed to the output end of the opening and closing regulator 62, and a semi-toothed ring 632 is rotatably provided on the outer wall of the arc-shaped base 631;
[0045] Motor housing 633 is fixed on the arc-shaped base 631, and a servo motor is disposed inside the motor housing 633; and
[0046] Gear 634 is disposed at the output end of the servo motor, and gear 634 meshes with the half-tooth ring 632.
[0047] In a preferred embodiment, a rotary cutter 635 is fixed to the bottom of the semi-toothed ring 632, and the rotary cutter 635 is used to cut the upper surface of the robot arm base plate.
[0048] It should be noted that during the cutting process of the rotary cutter 635 into the plate, the heat generated increases sharply and is concentrated at the cutting point. When the heat reaches a certain level, it will cause the inside of the metal plate to be processed to melt and deform. Therefore, in order to avoid the internal deformation of the metal plate, the cutting depth of the rotary cutter 635 is set not to exceed 1 / 10 of the thickness of the material plate to be processed.
[0049] Please refer to [link / reference needed] for further explanation. Figure 3 When the two arc-shaped bases 631 form a ring, the servo motor drives the gear 634 to rotate, thereby driving the half-tooth ring 632 to rotate. The bottom rotary cutter 635 rotates synchronously, so the cutting trajectory of the rotary cutter 635 matches the required stamping edge.
[0050] For specific implementation examples, please refer to [link / reference]. Figure 4 The 635 rotary cutter cuts the dividing points, transforming the stamping edge of the material plate to be stamped from one continuous body into two independent continuous bodies. Therefore, the unprocessed area will not be pulled by the material in the processing area, thereby reducing the deformation of the stamping edge during the stamping process and improving the integrity of the base plate.
[0051] In a preferred embodiment, a speed measuring device 636 is also provided on the arc-shaped base 631. The speed measuring device 636 is used to monitor the rotation speed of the rotary cutting blade 635, and the speed measuring device 636 is electrically connected to the stamping mechanism 5.
[0052] It should be noted that during the rotary cutting process, the interaction between the blade and the material plate with different hardness will cause different resistance levels in the rotary cutting blade 635, resulting in different rotation speeds.
[0053] For specific implementation examples, please refer to [link / reference]. Figure 5 The speed sensor 636 transmits the minimum rotation speed value v1 and the maximum speed value v2 of the rotary cutter 635 to the stamping mechanism 5 via a signal. The stamping mechanism 5 adjusts its corresponding stamping parameters (i.e., stamping force and stamping speed) according to (v1+v2) / 2 (i.e., the intermediate speed value) to achieve the optimal value, so that the stamping parameters match the hardness of the material plate to be stamped, reducing the amount and area of fracture marks generated on the stamping section during the stamping process, and improving the integrity of the base plate.
[0054] In practice, the moving feeding mechanism 2 transports the material plate to be processed to the area directly below the stamping mechanism 5. The pre-pressing mechanism 6 first moves down to cut the material plate, while simultaneously changing the stamping parameters of the stamping mechanism 5. Then, the pre-pressing mechanism 6 is withdrawn, and the stamping mechanism 5 moves down to complete the stamping operation.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
