When a mechanism is referred to as being "fixed to" another mechanism, it may be directly on the other mechanism or there may also be a centered mechanism. When a mechanism is considered to be "connected to" another mechanism, it may be directly connected to the other mechanism or there may be a centered mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it may be directly set on the other mechanism or there may be a centered mechanism at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0027] like Figures 1 to 5As shown, the utility model is a clamp forming device, comprising: an upper die 1, a lower die 2, a sheet material 4, a power source is arranged on the surface of the upper die 1, the upper die 1 is driven by the power source to move up and down, and the sheet material 4 is punched between the upper die 1 and the lower die 2 to form a clamp; a feed port 3 is fixedly installed on the lower die 2, and the sheet material 4 is fed through the feed port 3;

[0028] The upper die 1 includes: a fixing component 11 for fixing the sheet material 4; when the upper die 1 punches the sheet material 4, the fixing component 11 contacts the sheet material 4 and squeezes the sheet material 4 to prevent it from shaking, which causes deviation in the punching position and waste when the upper die 1 punches; a cleaning component 12 for cleaning the surface of the lower die 2; when the sheet material 4 is punched, the waste generated during the punching process and the debris brought into the mold cavity by the surface of the sheet material 4 are cleaned, and a loading component 13 for driving the sheet material 4 to be loaded; when the clamp is processed and formed, the sheet material 4 needs to be punched multiple times, and the punching distance needs to be strictly controlled to avoid deviation in the punching position and waste.

[0029] In the present application, when the upper mold 1 and the lower mold 2 are used for stamping, the sheet material 4 is fixed to prevent it from shifting and affecting the stamping, and the mold cavity is cleaned by the cleaning component 12. On the other hand, when the upper mold 1 and the lower mold 2 are separated, the sheet material 4 is driven to be loaded, which is independent of manual work to a certain extent and can be automatically operated. In addition, the loading distance is fixed, and there will be no stamping deviation, which will lead to waste generation.

[0030] The fixing assembly 11 includes: an extrusion rod 112 for fixing the sheet material 4, a flexible part 111 for preventing the extrusion rod 112 from rigidly contacting the sheet material 4, and the flexible part 111 can provide buffering when the extrusion rod 112 contacts the sheet material 4, which is preferably a spring; a limiting rod 113 slidably connected to the extrusion rod 112, and one end of the limiting rod 113 is fixedly connected to the upper mold 1. When the upper mold 1 and the lower mold 2 are closed, the extrusion rod 112 contacts the sheet material 4 to prevent the sheet material 4 from shaking. Then the upper mold 1 and the lower mold 2 continue to close the mold, and the extrusion rod 112 squeezes the flexible part 111. At the same time, the limiting rod 113 slides inside the extrusion rod 112 and limits the extrusion rod 112 to prevent the extrusion rod 112 from shaking under the drive of the flexible part 111, thereby affecting the fixation of the sheet material 4.

[0031] The cleaning assembly 12 includes: an air cavity 121 for storing gas, a piston 122 for pumping gas, when the upper mold 1 and the lower mold 2 are stamped, the piston 122 slides inside the air cavity 121 to eject the gas inside the air cavity 121, and an air jet hole 125. The surface of the air jet hole 125 is chamfered to expand the gas ejection range; an air pipe 124 connecting the air cavity 121 and the air jet hole 125, and a push rod 123 for driving the piston 122 to move. The push rod 123 is fixed on the surface of the lower mold 2. When the upper mold 1 moves downward, the push rod 123 pushes the piston 122 to move inside the air cavity 121, and ejects the gas inside the air cavity 121 through the air pipe 124 and the air jet hole 125. The gas blows away the impurities on the lower mold 2, thereby completing the cleaning and avoiding the accumulation of impurities on the lower mold 2, which affects the stamping of the sheet 4 and further affects the forming of the clamp.

[0032] The feeding assembly 13 includes: a feeding roller 1310 for pushing the sheet material 4 to move; two groups of feeding rollers 1310 are provided, and the surface is provided with friction patterns to increase the friction force of the contact surface with the sheet material 4; a bevel gear 138 and a bevel gear 139 that drive the feeding roller 1310 to rotate; a rotating member 136 that drives the bevel gear 138 and the bevel gear 139 to rotate; a spiral protrusion 137 fixedly connected to the rotating member 136; the spiral protrusion 137 is provided with multiple groups on the surface of the rotating member 136, and abuts against the The top head 134 on the spiral protrusion 137, when moving upward, abuts against the surface of the spiral protrusion 137 to drive the rotating member 136 to rotate, and the rotating member 136 drives the feeding roller 1310 to rotate through the bevel gear 138 and the bevel gear 2 139. There is a rounded corner on one side of the connection between the spiral protrusion 137 and the rotating member 136, so that when the top head 134 moves downward, it will not drive the rotating member 136 to rotate through the spiral protrusion 137, but will shrink through the rounded corner, thereby driving the sheet 4 to feed the material at a fixed distance when the mold is separated, which is more accurate and does not require manual operation.

[0033] The feeding assembly 13 also includes: a connecting rod 132 supporting the plug 134, a return spring 133 driving the plug 134 to retract and contract, the plug 134 is guided by the rounded corners to squeeze the return spring 133 and enter the connecting rod 132, so that when moving upward, the rotating member 136 is not driven to rotate, thereby not affecting the feeding of the sheet material 4, a fixed frame 131 supporting the connecting rod 132, the fixed frame 131 is covered on the outside of the rotating member 136, and can protect the rotating member 136, and the fixed frame 131 is fixed to the surface of the upper mold 1 and moves synchronously with the upper mold 1, the rotating shaft 135 connecting the rotating member 136 and the bevel gear 138, the rotating shaft 135 is rotatably connected to the lower mold 2 to support the rotating member 136, and the transmission gear 1311 is fixedly connected to one end of the feeding roller 1310, and the feeding roller 1310 drives another group of feeding rollers 1310 to rotate through the transmission gear 1311 for feeding.

[0034] When the upper mold 1 moves upward, the top head 134 abuts against the spiral protrusion 137 and is guided by the spiral protrusion 137, driving the rotating member 136 to rotate, and the feed roller 1310 is driven to rotate through the engagement of bevel gear 138 and bevel gear 2 139. The feed roller 1310 drives another set of feed rollers 1310 to rotate through the transmission gear 1311, and drives the sheet material 4 to move, so that the loading is more accurate and stable.

[0035] Working principle:

[0036] When the upper mold 1 moves upward, the top head 134 abuts against the spiral protrusion 137 and is guided by the spiral protrusion 137 to drive the rotating member 136 to rotate, and drives the feed roller 1310 to rotate through the engagement of bevel gear 138 and bevel gear 2 139. The feed roller 1310 drives another set of feed rollers 1310 to rotate through the transmission gear 1311, and drives the sheet 4 to move for loading. At the same time, the piston 122 slides inside the air cavity 121 to inject gas into the air cavity 121. When the upper mold 1 and the lower mold 2 are closed, after the extrusion rod 112 contacts the sheet 4, it can prevent the sheet 4 from shaking, and spray the gas inside the air cavity 121 through the air pipe 124 and the jet hole 125. The gas blows away the impurities on the lower mold 2, thereby completing the cleaning.
