Description

Technical Field

[0001] The invention relates to the technical field of stamping forming of stamping parts, in particular to an upper and lower unloading device suitable for a stamping manipulator to take parts. Background Art

[0002] After the stamping parts used in the vacuum interrupter are stamped and formed, the traditional unloading method is that when the mold opens to the highest point, the two ends of the hitting rod collide with the vertical hitting rods fixed on both sides of the bed, and the push block instantly pushes the part out of the concave model cavity, and the part will fall and jump to an uncertain position.

[0003] In manual stamping production, operators manually pick up parts that fall in different positions and put them into the parts basket. The parts are easily damaged due to falling and jumping. If all stamping production is manual, this traditional loading and unloading mode can also meet the daily stamping production. However, with the continuous increase in the output of stamping parts and the requirement of ensuring safe stamping production, the traditional manual stamping production mode cannot meet the new requirements of capacity improvement and safe production. The production mode of automatic loading and unloading of stamping must be promoted to achieve capacity improvement and safe stamping production. However, the position of the manipulator to take the parts must be fixed. The traditional loading and unloading mode makes it impossible for the stamping manipulator to take the parts normally, and continuous stamping production cannot be guaranteed. Therefore, the fixed position of the parts after stamping has become a prerequisite and necessary condition for the promotion of stamping automation. The original traditional stamping loading and unloading mode has hindered the application and promotion of the stamping automation production mode. Summary of the invention

[0004] In view of the problem in the prior art that a robot cannot pick up parts due to the unfixed position of parts after stamping, thereby affecting continuous stamping production, the present invention provides an unloading device suitable for a stamping robot to pick up parts.

[0005] The present invention is achieved through the following technical solutions: A discharge device suitable for a stamping robot to pick up parts comprises a fixed rod, a discharge adjustment rod, a pressure spring and a horizontal rod, wherein the horizontal rod is in contact with the vertical rod of a die punch; the fixed rod is arranged on a slide block, and the slide block is slidably arranged on a bed; one end of the discharge adjustment rod is fixedly connected to the fixed rod, and the other end is vertically suspended upward, the horizontal rod is slidably connected to the discharge adjustment rod, the pressure spring is sleeved on the discharge adjustment rod, and one end of the pressure spring abuts against the top of the adjustment rod, and the other end abuts against the horizontal rod.

[0006] Preferably, the mold punch includes a vertical hitting rod, a push block and a mold cylinder, the top of the mold cylinder is fixed to the bottom of the slider, the push block is slidably arranged in the mold cylinder, one end of the vertical hitting rod is connected to the push block, and the other end is in contact with the horizontal hitting rod.

[0007] Preferably, a T-block is provided on the fixing rod, and the T-block is connected to a T-slot originally provided on the sliding block.

[0008] Preferably, two unloading adjustment rods are provided, and the unloading adjustment rods are respectively located at both ends of the transverse rod, the length axis of the unloading adjustment rod is perpendicular to the length axis of the transverse rod, and each unloading adjustment rod is correspondingly provided with a pressure spring.

[0009] Preferably, the discharge adjustment rod and the fixed rod are connected by threads.

[0010] Preferably, a locking cap is provided between the discharge adjustment rod and the fixed rod for locking.

[0011] Preferably, a limiting platform is provided on the top of the unloading adjustment rod, and the top of the limiting platform abuts against the pressure spring.

[0012] Preferably, the limiting platform and the discharge adjusting rod are integrally formed.

[0013] Preferably, a spring positioning hole is provided on the horizontal striking rod, and the pressure spring is embedded in the spring positioning hole.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention discloses an upper unloading device suitable for a stamping manipulator to pick up parts. The pressure spring is set to ensure the stopping position of the parts with elastic potential energy, and the stamping and unloading of the parts are realized through the contact and interaction between the vertical hitting rod and the horizontal hitting rod. During the mold closing process, the hitting rod gradually pushes up the horizontal hitting rod, and at the same time, the pressure spring compresses the reserve elastic potential energy. As the upper and lower molds of the mold are finally closed, the elastic potential energy reserve of the pressure spring is the largest. When the mold is gradually opened, the elastic force of the pressure spring gradually decreases, but there is always a downward unloading force on the parts. Until the lower unloading force is zero, the downward unloading force transmitted by the pressure spring still exists, ensuring that the parts stop at a fixed position, thereby achieving the expected effect of the unloading device on the punch press, adapting to the necessary conditions for the stamping manipulator to pick up parts, and realizing the efficient picking and unloading of parts in the stamping manipulator. The coordinated work of its fixed rod, unloading adjustment rod, pressure spring and horizontal hitting rod and other components ensures the stability and reliability of the unloading process.

[0015] Furthermore, two adjusting rods are provided to adjust the force balance, ensure uniform force, avoid part bouncing, and ensure the position of parts.

[0016] Furthermore, the slider and the fixed rod are connected by a T-block and a T-slot structure, which enhances the stability and reliability of the connection and facilitates installation and removal. The T-slot on the original structure of the slider can avoid damaging the original structure of the slider, ensure the stable operation of the stamping work, and avoid performance loss or safety hazards caused by modification.

[0017] Furthermore, the unloading adjustment rod and the fixed rod are connected by a threaded connection, and a locking cap is provided for locking, which is convenient for adjusting the corresponding compression spring force according to the different unloading forces of the parts and ensures the stability of the connection.

[0018] Furthermore, the limit platform and the discharge adjustment rod are integrally formed, thereby enhancing the integrity and stability of the structure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with specific embodiments, which are intended to explain the present invention rather than to limit it.

[0022] The present invention discloses a loading and unloading device suitable for a stamping manipulator to pick up parts, referring to Figure 1 , 2 , including a fixed rod 1, a unloading adjustment rod 2, a pressure spring 3 and a horizontal rod 4, and the horizontal rod 4 is in contact with the vertical rod 5 of the mold punch; specifically, the mold punch includes a vertical rod 5, a push block 6 and a mold cylinder 7, the top of the mold cylinder 7 is fixed to the bottom of the slider 8, the push block 6 is slidably set in the mold cylinder 7, one end of the vertical rod 5 is connected to the push block 6, and the other end is in contact with the horizontal rod 4.

[0023] The fixing rod 1 is arranged on the slider 8, and the slider 8 is slidably arranged on the bed 9; specifically, a T-block is arranged on the fixing rod 1, and the T-block is connected to the T-slot originally arranged on the slider 8, and the fixed connection between the fixing rod 1 and the slider 8 is achieved through the interlocking of the T-slot and the T-block, which not only utilizes the original shape of the slider 8, but also does not require any destructive modification or processing of the slider 8 itself, thus avoiding performance loss or safety hazards caused by the modification, and the disassembly and installation between the two are simpler and faster, which helps to improve work efficiency and the maintainability of the machine tool, and also enhances the bonding strength between the two, ensuring the stability of the mechanical system during operation.

[0024] One end of the discharge adjustment rod 2 is fixedly connected to the fixed rod 1, and the other end is vertically suspended upward. The horizontal rod 4 is slidably connected to the discharge adjustment rod 2. The pressure spring 3 is sleeved on the discharge adjustment rod 2, and one end of the pressure spring 3 abuts against the top of the adjustment rod, and the other end abuts against the horizontal rod 4. Among them, the fixed rod 1 provides an installation fulcrum for the discharge adjustment rod 2 to achieve the connection between the fixed rod 1 and the slider 8, thereby realizing the transmission of force. When the mold is closed, the vertical rod 5 pushes the horizontal rod 4 to slide on the discharge adjustment rod 2, and the horizontal rod 4 compresses the pressure spring 3 to store energy. When the mold is opened and closed, the horizontal rod 4 presses the vertical rod 5 downward under the elastic action of the pressure spring 3, so that the vertical rod 5 drives the push block 6 to continue to press down on the part 14 to ensure the position of the part 14.

[0025] There are two unloading adjustment rods 2, and the unloading adjustment rods 2 are respectively located at both ends of the cross rod 4. The length axis of the unloading adjustment rod 2 is perpendicular to the length axis of the cross rod 4. A pressure spring 3 is correspondingly arranged on each unloading adjustment rod 2. The two unloading adjustment rods 2 are used to evenly bear force, ensure the balance and stability of force transmission, avoid deflection or distortion of the cross rod 4, and then ensure the force of the part 14, thereby improving the reliability and durability of the unloading system.

[0026] The discharge adjustment rod 2 is connected to the fixed rod 1 by a threaded connection, and a locking cap 13 is arranged between the discharge adjustment rod 2 and the fixed rod 1 for locking. By tightening the locking cap 13, the discharge adjustment rod 2 can be firmly locked on the fixed rod 1, ensuring that the connection between the two is more reliable. The locking cap 13 can not only realize the fixation of the two, but also provide the discharge system with a pressure spring 3 force adjustment function. Specifically, a limit table 15 is arranged on the top of the discharge adjustment rod 2, and the top of the limit table 15 abuts against the pressure spring 3. The limit table 15 and the discharge adjustment rod 2 are integrally formed. In this embodiment, the limit table 15 is a hexagonal structure. By loosening or tightening the locking cap 13, the relative position between the discharge adjustment rod 2 and the fixed rod 1 can be changed, thereby realizing the distance adjustment between the limit table 15 and the horizontal rod 4, and then adjusting the compression degree of the pressure spring 3, so as to realize the precise control of the discharge force, so that the system can more flexibly adapt to different discharge conditions, and improve the controllability and efficiency of the discharge process.

[0027] A spring positioning hole is provided on the horizontal rod 4, and the pressure spring 3 is embedded in the spring positioning hole. The spring positioning hole provides an installation groove for the pressure spring 3 to ensure the accurate positioning and stable operation of the pressure spring 3 in the unloading system, and prevents the pressure spring 3 from deflecting or shaking during the unloading process. At the same time, the spring positioning hole also provides a confined space for the pressure spring 3, which helps to control the compression and extension degree of the pressure spring 3. During the unloading process, when the horizontal rod 4 is subjected to external force, the pressure spring 3 will undergo corresponding deformation in the spring positioning hole to absorb and disperse these forces. Due to the limiting effect of the spring positioning hole, the deformation degree of the pressure spring 3 is effectively controlled, thereby ensuring the smooth and controllable unloading process. In addition, when the pressure spring 3 is damaged or fails due to long-term use or external force, the operator can easily remove the old spring through the spring positioning hole, which improves the maintainability of the unloading system and extends the service life of the system.

[0028] The utility model also comprises a workbench 10, a lower mold 12 and an air cushion push plate 11. The air cushion push plate 11 is slidably arranged in the workbench 10, and the lower mold 12 is fixed on the air cushion push plate 11 by bolts.

[0029] The present invention discloses an upper unloading device suitable for a stamping manipulator to take parts. The implementation principle is as follows: When the stamping die is in a closed state, the die punch lifts the vertical hitting rod 5 to the horizontal hitting rod 4 to the highest position, and the distance between the spring positioning hole of the horizontal hitting rod 4 and the limit platform 15 (the large end flange surface of the unloading adjusting rod 2) of the unloading adjusting rod 2 is reduced, so that the pressure spring 3 sleeved outside the unloading adjusting rod 2 is in an extreme compression state, and the pressure spring 3 stores pressure potential energy at this time. In the process of gradual mold opening, the lower unloading force gradually decreases, and the upper unloading force of the pressure spring 3 also gradually decreases. When the mold is opened to the highest position of the unloading plate, the lower unloading force is reduced to zero. At this time, the upper unloading force of the pressure spring 3 still presses the part 14 downward to ensure that the part 14 stays steadily on the end surface of the unloading plate and is fixed. Then the upper die continues to move up until the mold is opened to the maximum, the manipulator takes away the part 14, and then puts in a new sheet for stamping, unloading, taking and placing the part 14, and entering a cyclic stamping production process. The purpose of using this device is to ensure that after stamping is completed, the part 14 stays stably at a fixed position on the end face of the lower die 12 (the position of the part 14 dropped by the original traditional knocking unloading is uncertain), which provides the basic conditions for the robot to pick up the part 14 and ensures that the stamping robot can normally pick up the part 14 for automatic stamping production, thereby solving the basic condition problem that the position of the part 14 must be fixed when the stamping robot is used to pick up the part 14.

Those skilled in the art should understand that, without departing from the spirit and principles of the present invention, the technical solution can also be subjected to several simple modifications and substitutions, and these modifications and substitutions are also within the scope of protection covered by the claims.
