Description
Technical Field
[0001] This utility model relates to the technical field of processing devices in the field of household air conditioner parts, specifically an automatic material feeding and ejection device that is linked to the stroke of a stamping machine. Background Technology
[0002] Stamping is widely used in industrial manufacturing. Its advantages, such as saving materials and energy, high production efficiency, and relatively low operator skill requirements, have made it a crucial method for producing parts in many industries. However, traditional stamping operations have shortcomings in several aspects. Regarding automated feeding, existing automated feeding devices are typically driven by electrical equipment, which undoubtedly increases production costs. Furthermore, these devices require programming to match the stamping machine's movement frequency, making it difficult to quickly adapt to workpieces of different specifications and resulting in poor flexibility. In terms of automated part unloading, traditional stamping machines often rely on manual operation to retrieve stamped parts, which not only poses safety hazards but also reduces stamping efficiency.
[0003] However, common stamping machines use manual or electric motor-driven feeding and unloading, which can easily lead to mismatches in the stamping machine's stroke, resulting in low efficiency and high safety hazards. Furthermore, the waste material after stamping is piled up with the formed sheet material, requiring manual sorting, which increases the production cost for enterprises. Utility Model Content
[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides an automatic material ejection device that is linked to the stroke of a stamping machine. This solves the problem that when stamping machinery uses manual or motor-driven feeding and unloading, the movement stroke of the stamping machine is easily mismatched, resulting in low efficiency and high safety hazards.
[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: an automatic material ejection device linked to the stroke of a stamping machine, comprising a machine base, a gantry frame fixedly connected above the machine base, a cylinder fixedly connected above the gantry frame, an upper mold fixing plate fixedly connected below the cylinder, a rotating connecting column rotatably connected to the left side of the upper mold fixing plate, force transmission rods fixedly connected to both ends of the rotating connecting column, a swivel rotating fixing column and a fixing block fixedly connected below the force transmission rods, a swivel rotating fixing column rotatably connected to the outside of the swivel rotating fixing column, a swivel return spring fixedly connected above the swivel, and a fixing block fixedly connected to the other end of the swivel return spring.
[0006] During equipment operation, the sheet metal to be stamped is piled up and placed on the feeding plate. Under the action of the lifting spring, the feeding plate presses the top of the sheet metal against the bottom of the fixed baffle. When the cylinder raises the upper mold fixing plate, the upper mold fixing plate pulls the limiting post to slide to the right within the limiting post sliding groove via the force transmission rod. The lever fixed to the force transmission rod rotates the lever connected to the outside of the fixed post, which slides the sheet metal to be stamped to the right onto the lower mold. Then, the cylinder lowers the upper mold fixing plate, thus stamping the sheet metal into shape using the upper and lower molds. During the lowering process, the force transmission rod can push the limiting post to slide to the left in the limiting post sliding groove. At this time, the pawl will rotate to a horizontal state under the action of the new plate to be pressed, pulling the pawl return spring. When the limiting post reaches the leftmost side of the limiting post sliding groove, the pawl will disengage from the new plate to be pressed and return to vertical under the action of the pawl return spring. When the new plate to be pressed slides to the lower mold under the action of the pawl, the new plate to be pressed will push the stamped plate to slide to the right and slide into the formed plate collection trolley through the ramp. Through the operation of this equipment, the automatic loading and unloading of the equipment can be completed through the movement stroke of the stamping press, improving the working efficiency of the equipment.
[0007] Preferably, a fixed baffle is fixedly connected to the top of the equipment base. A limit post sliding groove is formed on the inner side of the fixed baffle. A limit post is slidably connected to the inner side of the limit post sliding groove. Force transmission rods are fixedly connected to both sides of the limit post. The limit post can be kept horizontally guided by the internal limit post sliding groove.
[0008] Preferably, a feeding port is provided on the left side of the equipment base. A lifting spring is fixedly connected to the bottom of the feeding port, and a feeding plate is fixedly connected to the top of the lifting spring. A feeding plate groove is provided on the side of the feeding port, and the feeding plate can move inside the feeding plate groove. This facilitates the placement of the sheet metal to be stamped, and the lifting spring holds the top of the sheet metal against the fixed baffle, maintaining the stability of the equipment during operation.
[0009] Preferably, a sliding column is fixedly connected above the upper mold fixing plate, a sliding column spring is fixedly connected above the sliding column, the lower part of the sliding column spring is fixedly connected to the top of the gantry frame, and an upper mold is fixedly connected below the upper mold fixing plate. This ensures that the upper mold fixing plate operates smoothly and stably under the drive of the cylinder.
[0010] Preferably, a lower mold placement slot is provided on the upper part of the equipment base, and a lower mold is fixedly connected to the upper part of the lower mold placement slot. This facilitates the replacement of the lower mold.
[0011] Preferably, a limiting block is fixedly connected above the equipment base. This keeps the plate within the limiting block and prevents it from deviating from its designated path.
[0012] Preferably, a ramp is provided on the right side of the equipment base, and a waste separation port is provided above the ramp. A waste collection drawer sliding groove, located on the front side of the equipment base, passes through the waste separation port. A waste collection drawer is slidably connected to the inner side of the waste collection drawer sliding groove. When a stamped sheet is pushed to the right by a new sheet to be pressed, the stamped sheet will cause the stamping waste to fall onto the ramp through the waste separation port into the waste collection drawer sliding in the waste collection drawer sliding groove. The stamped material then slides into the formed sheet collection trolley. Through the operation of this equipment, waste separation and collection can be achieved, saving manpower sorting time and reducing enterprise production costs.
[0013] Preferably, the right side of the equipment base is provided with a connecting groove for a forming sheet material collection trolley. A connecting protrusion for a forming sheet material collection trolley is slidably connected to the inner side of the connecting groove. A forming sheet material collection trolley is fixedly connected to the right side of the connecting protrusion. A trolley wheel is fixedly connected to the bottom of the forming sheet material collection trolley, and a trolley handle is fixedly connected to the top of the forming sheet material collection trolley. This allows for convenient transportation of the stamped sheets inside the forming sheet material collection trolley to the processing location.
[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides an automatic material ejection device that is linked to the stroke of a stamping press, which has the following advantages: 1. In this utility model, the sheet metal to be stamped is piled up and placed on a feeding plate. The feeding plate, under the action of a lifting spring, holds the top of the sheet metal against the bottom of a fixed baffle. When the cylinder drives the upper mold fixing plate to rise, the upper mold fixing plate pulls the limiting post to slide to the right within the limiting post sliding groove via a force transmission rod. A lever fixed to the force transmission rod rotates and rotates a lever connected to the outside of the fixing post, which slides the sheet metal to be stamped to the right onto the lower mold. Then, the cylinder drives the upper mold fixing plate to descend, thus stamping the sheet metal into shape using the upper and lower molds. During the descent of the plate, the force transmission rod pushes the limiting post to slide to the left within the limiting post sliding groove. At this time, the pawl rotates to a horizontal position under the action of the new plate to be pressed, pulling the pawl return spring. When the limiting post reaches the leftmost side of the limiting post sliding groove, the pawl disengages from the new plate to be pressed and returns to a vertical position under the action of the pawl return spring. As the new plate to be pressed slides to the lower mold under the action of the pawl, it pushes the stamped plate to slide to the right and slides onto the forming plate collection trolley via the ramp. Through the operation of this equipment, the automatic loading and unloading of the equipment can be completed through the movement stroke of the stamping press, improving the working efficiency of the equipment.
[0015] 2. When the stamped sheet is pushed to the right by the new sheet to be pressed, the stamped sheet will cause the stamped waste to fall into the sliding groove of the waste collection drawer through the waste separation port. The stamped waste slides into the formed sheet collection trolley. Through the operation of this equipment, waste separation and collection can be realized, saving manpower sorting time and saving enterprise production costs. Attached Figure Description
