Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamp production technology, and in particular to a stamping machine for producing flat iron clamps. Background Technology
[0002] A clamp is a fastener used to fix, support, or connect pipes, cables, poles, and other objects. It is typically made of metal (such as steel, stainless steel, or aluminum) or plastic, and comes in various shapes. Different types and sizes can be selected according to specific applications. The curved shape of the clamp is mainly determined by the mold. The design specifications of the clamp pressing mold and the materials used directly affect the quality of the clamp product. Most existing clamps are semi-circular. The clamp pressing mold usually uses a concave mold and a convex mold corresponding to the curvature. The flat iron is bent into the desired shape by the mutual pressing of the upper and lower molds.
[0003] A search of Chinese Patent Publication No. CN216297606U reveals a clamping stamping forming device, including an upper die and a lower die for stamping, and a hard mold block. The lower die has a notch at the shoulder of its cavity opening, and the hard mold block is detachably installed at the notch. The outer surface of the hard mold block coincides with the overall structure of the lower die. The strength and hardness of the hard mold block are greater than those of the lower die. By providing a replaceable hard mold block at the shoulder of the lower die's cavity opening, the hard mold block can be replaced only after wear and tear from long-term use, avoiding the need to replace the entire mold set.
[0004] During the continuous stamping process, the upper punch generates heat due to friction and impact, which may affect the properties of the material. Utility Model Content
[0005] The purpose of this invention is to provide a stamping machine for producing flat iron clamps in order to solve the above-mentioned problems.
[0006] This utility model achieves the above objectives through the following technical solutions:
[0007] A stamping machine for producing flat iron clamps includes a base plate, a lower die fixedly connected to the top of the base plate, a stamping mechanism above the lower die, a mounting plate, an upper die fixedly connected to the bottom of the mounting plate, and support columns fixedly connected to the four corners of the top of the base plate. Support plates are fixedly connected to the top of the support columns, and hydraulic cylinders are fixedly connected to the support plates. The mounting plate is fixedly connected to the bottom of the hydraulic cylinders. Two sets of air blowing pipes facing the upper die are fixedly connected to the bottom of the mounting plate, symmetrically arranged on both sides of the upper die. A ventilation cavity is formed inside the mounting plate, and an air supply pipe is fixedly connected to the top of the mounting plate, communicating with both the air supply pipe and the air blowing pipe. An air collection assembly is provided at the end of the air supply pipe away from the mounting plate. A section of the air supply pipe is a corrugated pipe. The air collection assembly includes an air collection cylinder fixedly connected to the top of the support plate. A piston plate is slidably connected between the inner walls of the air collection cylinder. The piston plate divides the interior of the air collection cylinder into an upper chamber and a lower chamber. A spring connects the piston plate and the support plate. The end of the air supply pipe away from the mounting plate is fixedly connected to the top of the air collection cylinder and communicates with the upper chamber of the air collection cylinder. An air inlet pipe is fixedly connected to the top of the air collection cylinder. A one-way valve is provided in the air inlet pipe. A vent hole is opened on the side wall of the air collection cylinder and communicates with the lower chamber. The air collection assembly also includes a drive assembly, which is used to drive the piston plate to move upward when the mounting plate moves upward.
[0008] Preferably, the drive assembly includes a piston rod, which is fixedly connected to the bottom of a piston plate. The bottom end of the piston rod extends out of a support plate and is fixedly connected to a top plate, which is located above the mounting plate. A spring is wound around the outer periphery of the piston rod.
[0009] Preferably, the top of the support plate has a through hole, through which the air supply pipe passes.
[0010] Preferably, the air blowing pipe is arc-shaped and located on both sides of the lower mold.
[0011] The beneficial effects are as follows: when the upper mold moves upward, airflow is supplied to the air supply pipe through the air supply component. The airflow is then sprayed out towards the upper mold through the air blowing pipe to cool the upper mold and prevent high temperature from affecting the material's performance.

[0024] Two sets of air blowing pipes 401 facing the upper mold 305 are fixedly connected to the bottom of the mounting plate 304. The air blowing pipes 401 are arc-shaped and the two sets of air blowing pipes 401 are symmetrically arranged on both sides of the upper mold 305. The air blowing pipes 401 are located on both sides of the lower mold 2 to avoid collision with the lower mold 2 when the air blowing pipes 401 move downward. A ventilation cavity is opened inside the mounting plate 304. An air supply pipe 402 is fixedly connected to the top of the mounting plate 304. The air supply pipe 402 passes through the through hole opened at the top of the support plate 302. A section of the air supply pipe 402 is a corrugated pipe. The air supply pipe 402 is connected to the ventilation cavity. The air blowing pipe 401 is connected to the ventilation cavity.
[0025] An air collection assembly is provided at the end of the air supply pipe 402 away from the mounting plate 304. The air collection assembly includes an air collection cylinder 403 fixedly connected to the top of the support plate 302. A piston plate 404 is slidably connected between the inner walls of the air collection cylinder 403. The piston plate 404 divides the interior of the air collection cylinder 403 into an upper chamber and a lower chamber. A spring 407 is connected between the piston plate 404 and the support plate 302. The end of the air supply pipe 402 away from the mounting plate 304 is fixedly connected to the top of the air collection cylinder 403 and communicates with the upper chamber of the air collection cylinder 403. An air inlet pipe 408 is fixedly connected to the top of the air collection cylinder 403. A one-way valve is provided in the air inlet pipe 408. External gas can enter the air collection cylinder 403 through the air inlet pipe 408, but the gas in the air collection cylinder 403 cannot be ejected through the air inlet pipe 408. A vent hole 409 is opened on the side wall of the air collection cylinder 403 and communicates with the lower chamber.
[0026] The gas collection assembly also includes a drive assembly for driving the piston plate 404 upward when the mounting plate 304 moves upward.

The top plate 406 is located above the mounting plate 304, and a spring 407 is wound around the outer periphery of the piston rod 405.
[0027] Working principle: During use, the sheet metal is placed on the lower mold 2. The hydraulic cylinder 303 is controlled to drive the mounting plate 304 to move the upper mold 305 downward to press the sheet metal. After the pressing is completed, the mounting plate 304 moves upward and abuts against the top plate 406 during the upward movement, driving the top plate 406 to move upward. The top plate 406 drives the piston rod 405 to move the piston plate 404 upward, squeezing the gas in the upper cavity of the gas collecting cylinder 403 into the mounting plate 304 through the air supply pipe 402, and then spraying it out towards the upper mold 305 through the air blowing pipe 401 to cool the upper mold 305 and prevent high temperature from affecting the material performance. When the mounting plate 304 moves downward again, the piston plate 404 moves downward to reset under the action of the spring force of the spring 407, and the external gas enters the gas collecting cylinder 403 through the air inlet pipe 408.
