[0052] Specifically, when the positioning shaft 26 rotates, the balance plate 261 arranged at its end is synchronously driven to rotate. Since a connecting plate 27 is arranged at the end of the balance plate 261, the connecting plate 27 moves synchronously with the balance plate 261. At the same time, when the connecting plate 27 moves, the telescopic member 271 is driven to move, wherein the telescopic member 271 is composed of an extrusion rod and a spring, and the support plate 29 is supported by the spring, so that the support plate 29 is always in a stable state. The support plate 29 is used to support automotive accessories.

[0053] Furthermore, an adjustment plate 263 is provided at one end of the balance plate 261 away from the push rod 262, a movable plate 28 is provided at the upper end of the adjustment plate 263, an adjustment block 281 is provided at the end of the movable plate 28, a support rod 282 is provided at the upper end of the adjustment block 281, the end of the support rod 282 passes through and extends to the lower end of the adjustment block 281, and a clamping block 283 is provided in the middle position of the movable plate 28, and the outer surface of the clamping block 283 is slidably connected to the inner wall of the arc groove 241.

[0054] Specifically, when the balance plate 261 moves, the adjustment plate 263 is synchronously driven to move. At the same time, when the adjustment plate 263 moves, the movable plate 28 arranged on the upper end thereof is driven to move, wherein the adjustment block 281 is composed of drive rods staggered horizontally and vertically. At the same time, when the adjustment plate 263 moves, the drive block is synchronously driven to move up and down.

[0055] The outer surface of the support rod 282 is provided with elastic components such as springs, which are used to limit the support rod 282 so that when the support rod 282 moves, it simultaneously drives the support plate 29 set at its end to move up and down, so that after the stamping is completed, the workpiece is ejected through the two support plates 29.

[0056] Furthermore, the protection assembly 3 is mounted on the upper end of the base 1, and the size of the workpiece is limited when it changes. The protection assembly 3 includes a fixed plate 31 connected to the base 1, and baffles 311 are symmetrically arranged at the ends of the fixed plate 31. A protection tube 32 is arranged at the ends of the fixed plate 31 and between the two baffles 311.

[0057] In this embodiment, the protective tube 32 is composed of a round rod, a sleeve and a spring, and the outer surface of the round rod is slidably connected to the inner wall of the sleeve, and the inner cavity of the sleeve is provided with a spring, and the end of the spring is connected to the round rod, so that when the round rod is forced to move, the spring is squeezed. The round rod is used to support the power block 33, so that the power block 33 is always in a stable state.

[0058] Furthermore, a power block 33 is provided at the end of the protective tube 32, a through hole 331 is provided in the middle of the power block 33, and a first limit rod 34 is rotatably mounted on the inner wall of the through hole 331.

[0059] Specifically, when the power block 33 rotates, the first limiting rod 34 is driven to move, and the power block 33 is driven to move by the first limiting rod 34, thereby squeezing the protective tube 32 and supporting it with the spring arranged inside the protective tube.

[0060] Furthermore, a positioning block 371 is provided at the lower end of the limiting shaft 37 , and the lower end of the positioning block 371 is connected to the baffle 311 , the upper end of the limiting shaft 37 passes through and extends to the outside of the baffle 311 , and an elastic member 372 is sleeved on the outer surface of the limiting shaft 37 .

[0061] Specifically, the elastic member 372 is an elastic component such as a spring, and the limit shaft 37 is limited by the elastic member 372, so that when the rotating block 35 is rotated under force, the limit shaft 37 is synchronously driven to rotate. Since the outer surface of the limit shaft 37 is sleeved with the elastic member 372, the limit shaft 37 is limited by the elastic member 372, so that the rotating block 35 is in a stable state as a whole.

[0062] Furthermore, guide rods 38 are symmetrically arranged at the ends of the fixing plate 31, and a slider 39 is slidably mounted on the outer surface of the guide rod 38. An arc plate 391 is arranged at one end of the slider 39, and a slot 392 is provided at the middle position of the slider 39. A second limiting rod 36 is rotatably mounted on the inner wall of the slot 392, and one end of the second limiting rod 36 away from the slider 39 is rotatably connected to the end of the rotating block 35.

[0063] Specifically, the outer surface of the arc plate 391 is provided with anti-slip components such as rubber, and the automobile accessories are limited by the arc plate 391. The automobile accessories are tightly fixed by the symmetrically arranged arc plates 391, so that when the workpiece shrinks during stamping, it can still fix the workpiece, thereby avoiding uneven force on different parts of the metal blank during processing.

[0064] At the same time, when the slider 39 moves, it cooperates with the second limiting rod 36 to push the rotating block 35 to rotate around the limiting shaft 37, and the limiting shaft 37 is supported by the elastic member 372, so that when the workpiece shrinks, the slider 39 is driven to move, so that it fits tightly to the outer surface of the workpiece, and at the same time, the overall position will not be offset during secondary processing.

[0065] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., and is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but has a small storage capacity, a simple input and output interface, and low functional consumption.

[0066] Embodiment 2:

[0067] See also Fig. 9 A safety type automobile parts forging machine processing method comprises the following steps:

[0068] S1. When the positioning shaft 26 rotates, the balancing plate 261 disposed at its end is synchronously driven to rotate. Since a connecting plate 27 is disposed at the end of the balancing plate 261, the connecting plate 27 moves synchronously with the balancing plate 261.

[0069] S2. When the connecting plate 27 moves, the telescopic member 271 is driven to move, and the supporting plate 29 is supported by the spring;
