Description

Technical Field

[0001] The utility model relates to the technical field of stamping forming, in particular to a stamping device for measuring the transverse fracture strength. Background Technique

[0002] Stamping is a forming processing method that relies on a press and a die to apply external force to plates, strips, pipes, profiles, etc., so that they undergo plastic deformation or separation, thereby obtaining stamping parts with the required shape and size. For products such as alloys, most of them place the materials on the stamping die, and the punch of the stamping machine directly applies pressure to the materials to deform them into the required shape and size to obtain finished products. However, due to the lack of necessary pressure detection function in the existing stamping machines, the size of the pressure cannot be accurately controlled, the stamping accuracy is low, and it is easy to cause the materials to be accidentally fractured and damaged due to excessive force, affecting the quality of the finished products. Content of the Utility Model

[0020] The present utility model will be described in detail below with reference to the drawings.

[0021] As Figures 1 to 2 shown, a stamping device for measuring the transverse fracture strength of the present utility model includes an upper punch seat 1, a lower punch seat 2 spaced from the upper punch seat 1, an upper stamping part 3 detachably connected to the upper punch seat 1, a lower stamping part 4 detachably connected to the lower punch seat 2, a pressure sensor 5 provided on the lower stamping part 4, and a limiting part 6 provided on the lower punch seat 2. The limiting part 6 extends in a direction away from the lower punch seat 2, and the lower punch seat 2 abuts against the upper punch seat 1 through the limiting part 6. The upper stamping part 3 moves closer to the lower stamping part 4 to press and bend the material placed between the upper stamping part 3 and the lower stamping part 4.

[0022] During operation, first, the alloy material to be tested is placed into the lower punch 4 by an external feeding mechanism. Then, an external driving mechanism is drivingly connected to the upper punch seat 1 to cause the upper punch seat 1 to move downward and approach the lower punch seat 2, further driving the upper punch 3 to descend to the position of the lower punch 4. The upper punch 3 applies a force to press on the lower punch 4, and the alloy material to be tested is forcefully extruded until it breaks. After the alloy material to be tested breaks, the pressure sensor 5 accurately detects the load F when the alloy material to be tested breaks under the applied force, and measures the groove width L of the arc pressing groove 44, the width b and height h of the alloy material to be tested. Then, in combination with the correction coefficient k obtained from the test before work, the transverse fracture strength R of the alloy material to be tested can be accurately calculated through the following formula tr : R tr =(3kFL) / (2bh 2 ). Then, the alloy material to be punched is placed into the lower punch 4 by an external feeding mechanism. The upper punch 3 of the upper punch seat 1 is driven by an external driving mechanism to abut and press on the lower punch 4, and the lower punch seat 2 abuts against the upper punch seat 1 through the stopper 6, effectively restricting the lifting and moving stroke of the upper punch seat 1, causing the alloy material to be press-bent to obtain a punched part with the required shape and size. At the same time, it also ensures that the force on the alloy material does not exceed the maximum load value range and does not exceed the maximum transverse fracture strength value, avoiding accidental fracture damage of the alloy material during the punching process, effectively improving the working stability during the punching process, reducing the working difficulty, and improving the working efficiency. The utility model realizes accurate measurement of the transverse fracture strength, has a good pressure detection function, accurately controls the magnitude of the pressure, has high punching accuracy, and improves the quality of the finished product.

[0023] The upper punch 3 of this embodiment includes an upper mounting seat 31, an upper punch head 32 disposed on the upper mounting seat 31, and first mounting screws 33 disposed on both sides of the upper mounting seat 31. An arc pressing block 34 is disposed at one end of the upper punch head 32 away from the upper mounting seat 31. Specifically, the upper punch 3 is of a split structure and is respectively threadedly connected to both sides of the upper mounting seat 31 by two first mounting screws 33, which helps to replace and use upper punch heads 32 of different specifications and sizes to meet different working requirements. An arc pressing block 34 is disposed at one end of the upper punch head 32 away from the upper mounting seat 31. The arc smooth structure of the arc pressing block 34 has good force uniformity, buffers the excessive punching force on the alloy material during punching, and can also avoid the fracture of the alloy material during the punching process, with good punching effect and improved punching quality.

[0024] The arc pressing block 34 of this embodiment is provided with a pressing pad 35, and the pressing pad 35 is sleeved on the outer side of the arc pressing block 34. Specifically, the pressing pad 35 is sleeved on the outer side of the arc pressing block 34. When the arc pressing block 34 presses on the alloy material through the pressing pad 35, during the process of the pressing pad 35 closely fitting with the alloy material, the air between the pressing pad 35 and the alloy material is effectively extruded, thus forming a function similar to a vacuum chuck, effectively fixing the position of the alloy material, and avoiding the situation of position deviation of the alloy material during the stamping process, with good positioning effect.

[0025] The lower stamping part 4 of this embodiment includes a lower mounting base 41, a lower pressing base 42 arranged on the lower mounting base 41, and second mounting screws 43 arranged on both sides of the lower mounting base 41. One end of the lower pressing base 42 away from the lower mounting base 41 is provided with an arc pressing groove 44, the arc pressing block 34 is accommodated in the arc pressing groove 44, one end of the lower pressing base 42 close to the arc pressing groove 44 is provided with a U-shaped groove 45, and the pressure sensor 5 is arranged in the U-shaped groove 45. Specifically, the lower stamping part 4 is of a split structure and is respectively threadedly connected to both sides of the lower mounting base 41 through two second mounting screws 43, which helps to replace and use the lower pressing bases 42 of different specifications and sizes to meet different working requirements. One end of the lower pressing base 42 away from the lower mounting base 41 is provided with an arc pressing groove 44, and the arc pressing block 34 is pressed and accommodated in the arc pressing groove 44, so as to cause the alloy material to be bent and formed under extrusion, with good structural stability. The lower pressing base 42 installs the pressure sensor 5 through the U-shaped groove 45, which helps the pressure sensor 5 accurately measure the force received by the alloy material.

[0026] Guide columns 11 are arranged on both sides of the upper punching seat 1 of this embodiment, and guide grooves 21 are arranged on both sides of the lower punching seat 2, and the guide columns 11 are accommodated in the guide grooves 21. Specifically, the upper punching seat 1 is connected to the guide grooves 21 through the guide columns 11, playing a good guiding role, improving the smoothness of the up and down movement of the upper punching seat 1, and having high working stability.
