Description

Technical Field

[0001] This utility model relates to the field of punch press feeding technology, and in particular to an automatic quantitative feeding device for punch press production and processing. Background Technology

[0002] A punch press is essentially a stamping press. In national production, stamping technology has become increasingly widely used due to its advantages over traditional machining: saving materials and energy, high efficiency, lower operator skill requirements, and the ability to produce products that cannot be achieved through machining using various molds. Stamping production primarily targets sheet metal. Through molds, it can produce blanking, punching, forming, deep drawing, trimming, fine blanking, shaping, riveting, and extruded parts, etc., and is widely applied in various fields. However, existing automatic quantitative feeding devices for punch press production still have problems such as the inability to accurately adjust the feeding amount according to demand and the inability to stably drive the material feeding operation.

[0003] Therefore, it is very necessary to invent an automatic quantitative feeding device for punch press production and processing. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an automatic quantitative feeding device for punch press production, solving the issues that existing automatic quantitative feeding devices for punch press production still cannot accurately adjust the feeding amount according to demand and cannot stably drive the material for feeding. An automatic quantitative feeding device for punch press production includes a support base, a lower stamping die, a support frame, a hydraulic structure, guide pillars, an upper stamping die, a feeding structure, and material. The lower stamping die is fixedly installed at the lower end of the support base, and the support frame is fixedly installed at the upper end of the support base. The hydraulic structure is fixedly installed on the support frame. The upper stamping die is fixedly installed at the lower end of the hydraulic structure. The guide pillars are slidably installed on both sides of the support frame and connected and fixed to the upper stamping die. The feeding structure is fixedly installed inside the support base.

[0005] The material is slidably supported inside the stamping die; the feeding structure clamps and fixes one end of the material.

[0006] The upper stamping die includes a stamping die block, a fixed holding block, a hydraulic connecting seat, and a guide post connecting seat; the fixed holding block is fixedly installed at both ends of the stamping die block; the stamping die block is connected and fixed to the hydraulic structure through the hydraulic connecting seat fixed above it; the fixed holding block is connected and fixed to the guide post through the guide post connecting seat fixed above it.

[0007] The feeding structure includes a feeding push rod, a support arm, an upper holding block, a lower holding block, an extension frame, and a clamping push rod. The feeding push rod is fixedly installed inside the support base, and the support arm is fixedly installed at one end of the feeding push rod. The upper holding block is fixedly installed below the support arm. The lower holding block is located below the upper holding block. An extension frame is fixedly installed on the outer sides of the upper and lower holding blocks, and the extension frames on the outer sides of the upper and lower holding blocks are connected by the clamping push rod.

[0008] The upper stamping die can be reciprocated vertically by a hydraulic structure, which can move closer to or further away from the lower stamping die. A shearing blade is provided at the bottom of the stamping die block. The fixed holding block is made of steel with the same material as the stamping die block, and its thickness is less than that of the stamping die block. The height difference between the fixed holding block and the stamping die block is filled by two rubber pads. The rubber pad under the fixed holding block will deform under pressure.

[0009] The feeding structure contains an electric push rod, the extension length of which is equal to the material feeding amount. The feeding push rod can be replaced with different lengths according to different feeding requirements. The upper and lower clamping blocks are made of two rubber blocks, and they can clamp or release the material by controlling the clamping push rod. After clamping the material, the upper and lower clamping blocks can be pushed forward by the feeding push rod.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The upper stamping die of this utility model is set up with a hydraulic structure to drive precise downward pressing along the guide post. The stamping die block with shearing blade cooperates with the lower stamping die to complete the blanking process of the material. At the same time, the fixed holding blocks on both sides use rubber buffers to flexibly hold the material to prevent displacement. The hydraulic connecting seat transmits hydraulic power, and the guide post connecting seat ensures the stability of movement. The whole and the feeding structure work together to realize automatic feeding and stamping cycle, which has the characteristics of high processing accuracy, stable positioning and prevention of material damage.

[0012] 2. The feeding structure of this utility model uses the precise extension and retraction of the feeding push rod to drive the support arm, so that the upper and lower clamping blocks form an adjustable clamping force under the control of the clamping push rod. This reliably clamps the material and guides it along the extended frame to complete the quantitative pushing. Finally, the material is accurately delivered to the processing position of the lower stamping die, realizing the timing coordination with the action of the upper stamping die, and ensuring the continuity of the fully automatic stamping operation and the feeding accuracy.
