Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a stamping die with a detachable and replaceable die head. Background Technology

[0002] Currently, stamping dies are a special type of equipment used in cold stamping to process materials into parts or semi-finished products. Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts. Because stamping dies are prone to wear after long-term use, if they are not replaced, it will affect subsequent stamping.

[0003] However, after prolonged use, the die head of many existing stamping devices will wear out. The existing stamping devices are generally fixed to the die head with long bolts. This connection method is inconvenient to disassemble and assemble, and the bolts are prone to corrosion after long-term use, so there is a problem of slow disassembly and assembly.

[0004] To address this issue, the present invention provides a stamping die with a detachable and replaceable die head. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a stamping die with a detachable and replaceable die head, thus solving the aforementioned problems.

[0007] Preferably, the cross-section of each set of grooves and each set of slide bars is trapezoidal.

[0008] Preferably, a drive groove is horizontally formed on the inner wall of the bottom end of the mounting bracket. A dual-axis motor is fixedly installed at the middle position inside the drive groove. Each dual-axis motor is fixedly installed with a threaded rod. The ends of the two sets of threaded rods that are far apart from each other are rotatably connected to the inner wall of the drive groove. Slider blocks are symmetrically slidably installed inside the drive groove. Each set of sliders is threadedly connected to the threaded rod at the corresponding position. An L-shaped plate is fixedly installed at the top of each set of sliders. A retaining strip is longitudinally fixedly installed at the bottom end of the two sets of L-shaped plates that are close to each other. The mounting plate has retaining grooves on both sides that correspond to the retaining strips.

[0009] Preferably, the two sets of threaded rods have opposite thread directions.

[0010] Preferably, the mounting bracket has a vertical through-threaded limit screw, and the mounting plate has a limit hole corresponding to the limit screw.

[0011] Preferably, the frame has an internal mounting groove, a collection drawer is slidably mounted inside the mounting groove, and a handle is fixedly mounted on the outer wall of the front end of the collection drawer.

[0014] Beneficial effects

[0015] This invention provides a stamping die with a detachable and replaceable die head. Compared with the prior art, it has the following advantages:

[0016] When the upper template needs to be replaced, the operator can install the new mounting plate under the support frame through the sliding groove and sliding strip. Then, by rotating the limit screw, it can be engaged with the limit hole at the top of the mounting plate, thereby preventing the mounting plate from moving longitudinally and making the upper template more stable. In addition, the operator can start the dual-axis motor through the control panel, which drives the two sets of locking strips to engage with the locking groove, thereby further improving the stability of the upper template after installation. The above settings make this device easy to install and remove the upper template. Attached Figure Description

[0023] 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.

[0024] Example 1:

[0025] Please see Figure 1-5 A stamping die with a detachable and replaceable die head includes a frame 1, a support frame 2 fixedly installed at the top of the frame 1, a lower template 3 fixedly installed at the top of the frame 1, a hydraulic cylinder 4 fixedly installed at the top of the support frame 2, a telescopic rod 5 fixedly installed at the output end of the hydraulic cylinder 4, a mounting frame 6 fixedly installed at the other end of the telescopic rod 5, a mounting plate 7 provided below the mounting frame 6, two sets of sliding grooves 8 longitudinally opened at the bottom end of the mounting frame 6, a sliding strip 9 fixedly installed at the top of the mounting plate 7 at the corresponding position of each set of sliding grooves 8, each set of sliding strips 9 being slidably connected to the sliding groove 8 at the corresponding position, and an upper template 10 fixedly installed at the bottom end of the mounting plate 7.

[0026] The cross-sections of each set of slide grooves 8 and each set of slide bars 9 are trapezoidal in shape.

[0027] The mounting bracket 6 has a vertical through-threaded connection with a limit screw 18, and the mounting plate 7 has a limit hole 19 corresponding to the limit screw 18.

[0028] The frame 1 has an internal mounting slot 20, and a collection drawer 21 is slidably installed inside the mounting slot 20. A handle 22 is fixedly installed on the outer wall of the front end of the collection drawer 21.

[0029] A control panel 24 is fixedly installed on the outer wall of the front end of the frame 1. The hydraulic cylinder 4 and the dual-axis motor 12 are all electrically connected to the control panel 24.

[0030] Rubber pads 23 are fixedly installed at the four corners of the bottom of the frame 1.

[0031] When the upper template 10 needs to be disassembled and replaced, the operator can slide the slide bar 9 on the new mounting plate 7 into the groove 8 opened below the mounting frame 6. Since the cross-section of both the groove 8 and the slide bar 9 is trapezoidal, it can prevent the mounting plate 7 from falling vertically. Then, the operator can rotate the limit screw 18 to engage with the limit hole 19 at the top of the mounting plate 7, thereby preventing the mounting plate 7 from moving longitudinally and fixing the upper template 10, which improves the stability of the upper template 10 after installation. Then, the operator can start the hydraulic cylinder 4 through the control panel 24 to drive the telescopic rod 5 to extend and retract, thereby driving the upper template 10 to perform stamping processing on the workpiece. Finally, the collection drawer 21 in this device can collect the workpiece after stamping processing, thus making the device more practical.

[0032] Example 2:

[0033] Please see Figure 1-5 This embodiment provides a technical solution based on embodiment one: a drive groove 11 is horizontally opened on the inner wall of the bottom end of the mounting bracket 6. A dual-axis motor 12 is fixedly installed in the middle position inside the drive groove 11. Each dual-axis motor 12 is fixedly installed with a threaded rod 13. The ends of the two sets of threaded rods 13 that are far apart from each other are rotatably connected to the inner wall of the drive groove 11. Slider 14s are symmetrically slidably installed inside the drive groove 11. Each set of sliders 14 is threadedly connected to the threaded rod 13 at the corresponding position. An L-shaped plate 15 is fixedly installed at the top of each set of sliders 14. A retaining strip 16 is longitudinally fixedly installed at the bottom end of the two sets of L-shaped plates 15 that are close to each other. The mounting plate 7 has a retaining groove 17 on both sides that corresponds to the retaining strip 16.

[0034] The two sets of threaded rods 13 have opposite thread directions.

[0035] When the new upper template 10 is installed, the staff can also start the dual-axis motor 12 through the control panel 24, so that the two sets of spiral rods 13 with opposite directions of rotation can rotate at the same time, thereby driving the two sets of locking strips 16 to engage with the slots 17, which further improves the stability of the upper template 10 after installation.
