Description

Technical Field

[0001] This utility model relates to a device for stamping test rods, and more particularly to a desktop device for stamping test rods. Background Technology

[0002] During the forging process, test bars are used to check whether the mechanical properties of the forging meet the requirements. These test bars are usually processed into mechanical property test bars, and then tensile tests are conducted to test mechanical properties such as tensile strength, yield strength, elongation, and reduction of area. In addition, some forgings require test bars to be taken from the forging body itself, as test bars taken from the body are more representative of the forging's performance.

[0003] To ensure that each test bar corresponds to the type of forging material, so that the test bar can be accurately positioned after the tensile test and the performance results of the corresponding forging material can be matched based on the tensile test results of the test bar, the current method is to stamp steel marks on the surface of the test bar using a steel stamping machine, so that the test results can be matched after the bar tensile test.

[0004] However, since most test bars are cylindrical, the transmission method involves manually fixing the test bar and then stamping it with a stamping machine. This stamping method is not very safe, and the test bar is prone to misalignment when stamping, which affects the stamping effect. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a desktop test bar stamping device that can adapt to stamping test bars of different diameters and is flexible in use.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A desktop test bar stamping device includes a stamping machine. The stamping machine has upright plates fixedly connected to its front and rear ends. A base plate is provided at the bottom of the two upright plates. A gap exists between the bottom of the stamping machine and the base plate. A test bar fixing mechanism for clamping and fixing the test bar is provided within the gap. The test bar fixing mechanism consists of a V-shaped frame and a fixing frame positioned on top of the V-shaped frame. A V-shaped groove is provided on the top of the V-shaped frame along its front-to-back length. The test bar is placed within the V-shaped groove. The fixing frame is mounted on the V-shaped frame at a position above the V-shaped groove, and is used to clamp and fix the test bar placed within the V-shaped groove.

[0007] Furthermore, the top of the base plate is provided with an upward-opening pressure groove, and the two upright plates are inserted into the front and rear ends of the pressure groove. A pressure plate is provided in the part between the two upright plates in the pressure groove to fit into it, and the V-shaped frame is provided on the top of the pressure plate.

[0008] Furthermore, the top surface of the pressure plate is inclined downward to one side, the bottom surface of the fixing frame is an inclined surface that matches the structure of the top surface of the pressure plate, and the top surface of the fixing frame is horizontal after it is installed on the pressure plate.

[0009] Furthermore, an oblique protrusion is provided on the inner side of the upright plate near the bottom, which constitutes a locking block. The end of the pressure plate near the bottom is inclined inward, and the inwardly inclined part matches the locking block structure.

[0010] Furthermore, the front and rear ends of the V-shaped frame are fixedly connected to the corresponding two upright plates by limiting pins.

[0011] Furthermore, the fixing frame is provided with weight-reducing grooves with outward openings on both the left and right sides, and the cross-section of the weight-reducing grooves is U-shaped.

[0012] Furthermore, the bottom of the weight-reducing groove near the outer side is provided with an upwardly protruding force-bearing step along its length.

[0013] Furthermore, the fixing frame includes a pressure block, which has an arch bridge-shaped structure and a slot that is connected front and back at its bottom. The slot corresponds vertically to the V-shaped groove. A threaded adjustment hole that is connected vertically is provided at the center of the top of the pressure block, and a limiting screw that is threadedly engaged with the threaded adjustment hole is provided in the threaded adjustment hole.

[0014] Furthermore, the two sides of the pressure block are fixedly connected to the V-shaped frame by bolts.

[0015] Compared with the prior art, the advantages of this utility model are: this desktop test bar stamping device can make the test bar tangent to the bottom of the stamping machine by adjusting the height of the pressure plate, the height of the V-shaped frame, and the angle of the V-groove. The height or angle of one or more components can be adjusted according to the specific situation to adapt to the assembly of test bars of different diameters, which facilitates the stamping machine to stamp the test bars.

[0024] Example

[0025] Please refer to the instruction manual attached. Figure 1 and 2 As shown, the instruction manual is attached. Figure 1 and 2The diagram illustrates a specific embodiment of a desktop test rod stamping device of this utility model, used for printing external stamped marks on test rods 6. The desktop test rod stamping device includes a stamping machine 3 for stamping external marks on test rods 100. The stamping machine 3 is model DKSC-30*110-ZK, and has upright plates 2 fixedly connected to its front and rear ends. The upright plates 2 are rectangular in structure and are fixedly connected to the end faces of the stamped marks 3 by screws. A base plate 1 is provided at the bottom of the two upright plates 2. For convenient installation and removal of the upright plates 2 on the base plate 1, please refer to the appendix of the instruction manual. Figure 3 and 5 As shown, the top of the base plate 1 is provided with an upward-opening pressure groove 11. It should be noted that the front-to-back length of the pressure groove 11 matches the front-to-back distance between the two upright plates 2 of the stamping machine 3, and the width of the pressure groove 11 matches the left-to-right width of the upright plates 2. The two upright plates 2 are inserted into the front and back ends of the pressure groove 11. A pressure plate 5 is provided in the pressure groove 11 between the two upright plates 2, and the pressure plate 5 presses the two upright plates 2 tightly against the pressure groove 11, thus fixing the two upright plates 2 connected to the stamping machine 3 onto the base plate 1. (See attached instruction manual.) Figure 6 As shown, in order to enable the pressure plate 5 to hold the bottom of the two upright plates 2 installed in the pressure groove 11, and to ensure the balance of the two upright plates 2 after installation in the pressure groove 11, the inner side of the upright plate 2 near the bottom is provided with an oblique protrusion, which is an outwardly inclined slope with an inclination angle of 15°. This oblique protrusion constitutes a positioning block 22. The end of the pressure plate 5 near the bottom is inclined inward, and this inwardly inclined part matches the structure of the block 22. After the pressure plate 5 presses against the two upright plates 2 in the pressure groove 11, the lower end of its end fully cooperates with the block 22, ensuring that the upright plates 2 will not slip out of the pressure groove 11, and ensuring the consistency of the height of the two upright plates 2 in the slot 11, thereby ensuring the balance of the stamping machine 3 on the upright plate 1, and also preventing the stamping machine from jumping up and down during operation; there is a gap between the bottom of the stamping machine 3 and the base plate 1, and a test bar fixing mechanism 4 for clamping and fixing the test bar 6 is provided in the gap; see the attached instruction manual. Figure 3 and 7 As shown, the test bar fixing mechanism 4 consists of a V-shaped frame 41 and a fixing frame 42 disposed on top of the V-shaped frame 41. (See attached instruction manual.) Figure 3 and 5 As shown, the V-shaped frame 41 is disposed on the top of the pressure plate 5. The front and rear ends of the V-shaped frame 41 are aligned with the spacing between the front and rear upright plates 2. To ensure that the V-shaped frame 41 can be fixed on the top of the pressure plate 5, please refer to the appendix of the instruction manual. Figure 1 , 2As shown in Figure 4, the V-shaped frame 41 is fixedly connected to the corresponding two upright plates 2 at both ends by limiting pins 21. Specifically, the V-shaped frame 41 has positioning holes at both ends, and the two upright plates 2 have pin holes corresponding to the positioning holes after the V-shaped frame 41 is installed on the pressure plate 5. The V-shaped frame 41 is fixedly connected to the corresponding positioning holes by the limiting pins 21 passing through the pin holes, thus limiting the position of the V-shaped frame 41 between the two upright plates 2, and thus limiting the position of the V-shaped frame 41 on the pressure plate 5. After the fixing frame 42 is installed on the pressure plate 5, its top surface is horizontal. To facilitate the removal of the V-shaped frame 41 from under the stamping machine 3 and to facilitate the installation of the test bar 6 on the V-shaped frame 41, please refer to the appendix of the instruction manual. Figure 3 As shown, the top surface of the pressure plate 5 is inclined downwards to one side, and the bottom surface of the fixing frame 42 is an inclined surface that matches the structure of the top surface of the pressure plate 5. The V-shaped frame 41 can slide obliquely relative to the pressure plate 5, ensuring that the top surface of the V-shaped frame 41 is horizontal when it moves. This facilitates the engagement of the test bar 6 on the V-shaped frame 41 with the bottom of the stamping machine 3, while avoiding sliding friction interference during movement. It also facilitates the replacement of pressure plates 5 and V-shaped frames 41 of different heights, making it easy to accommodate test bars 6 of different diameters. To facilitate the positioning of the test bar 6 on the V-shaped frame 41 and limit its horizontal position, a V-groove 411 is provided on the top of the V-shaped frame 41 along its front-to-back length. The test bar 6 is placed in the V-groove 411, which limits the horizontal position of the test bar 6. The fixing frame 42 is mounted on the V-shaped frame 41 above the V-groove 411, and is used to clamp and fix the test bar 6 placed in the V-groove 411. (See attached instruction manual.) Figure 3 and 7 As shown, the fixing frame 41 has outward-opening weight-reducing grooves 412 on both the left and right sides. The cross-section of the weight-reducing groove 412 is U-shaped, and the weight-reducing groove 412 passes through the front and rear ends of the fixing frame 41. See the appendix of the instruction manual. Figure 7 As shown, the bottom of the weight-reducing groove 412 near the outer side is provided with an upwardly protruding force-bearing step 4121 along its length direction. It should be noted that in this embodiment, at least one weight-reducing groove 412 is provided with a force-bearing step 4121, and the weight-reducing groove 412 with the force-bearing step 4121 is the weight-reducing groove 412 at the lowest point of the bottom slope of the V-shaped frame 41, which is convenient for manually holding the force-bearing step 4121 to pull the V-shaped frame 41 downward along the slope of the top surface of the pressure plate 5, and is also convenient for pushing it onto the pressure plate 5.

[0026] To facilitate the clamping and fixing of the test bar 6 placed on the V-shaped frame 41 by the fixing bracket 42, please refer to the instruction manual appendix. Figure 7As shown, the fixing frame 42 includes a pressure block 421, which has an arched structure and a slot 422 at its bottom that is connected front to back. The slot 422 corresponds vertically to the V-groove 411. The test bar 6 is located between the corresponding slot 422 and the V-groove 411. To avoid the pressure block 421 interfering with the stamping machine 3, the pressure block 421 is positioned on the V-frame 41 near its front end. To facilitate limiting the position of the test bar 6 below the pressure block 421, a threaded adjustment hole 423 is provided at the center of the top of the pressure block 421. A limiting screw 424 is provided in the threaded adjustment hole 423 and is threadedly engaged with it. The limiting screw 424 is screwed into the threaded adjustment hole 423. The top of the test bar 6 placed in the V-groove 411 is limited by the pressure block 421 near the front end. The height of the test bar 6 can be adjusted by rotating the limiting screw 424 so that the bottom of the limiting screw 424 abuts against the top of the test bar 6. The top of the test bar 6 is tangent to the bottom of the stamping machine 3 at the position behind the limiting block 421. The stamping machine 3 and the limiting screw 424 cooperate with the V-shaped frame 41 to clamp the test bar 6, so that the stamping machine 3 can stamp the clamped test bar 6.

[0027] See the attached instruction manual. Figure 7 As shown, to facilitate the installation and fixation of the pressure block 421 on the V-shaped frame 41, and also for easy disassembly, both sides of the pressure block 421 are fixedly connected to the V-shaped frame 41 with bolts; for details on the bolted connection between the pressure block 421 and the V-shaped frame 41, please refer to the appendix of the instruction manual. Figure 1 As shown, the top of the V-shaped frame 41 is provided with connecting holes on the left and right sides of the V-shaped groove 411. The connecting holes are vertically connected to the weight reduction groove 412. The pressure block 421 is provided with positioning holes that are vertically connected to the connecting holes. The corresponding connecting holes and positioning holes are fixed to the V-shaped frame 41 by bolts and matching nuts. In order to facilitate the fine adjustment of the front and back position of the pressure block 421 on the top of the V-shaped frame 41, the connecting hole is an elongated hole, which is set along the length direction of the V-shaped groove 411.

[0028] This desktop test bar stamping device can achieve perfect tangency between the test bar 6 and the bottom of the stamping machine 3 by adjusting the height of the pressure plate 5, the height of the V-shaped frame 41, and the angle of the V-groove 411. The height or angle of one or more components can be adjusted according to specific circumstances to adapt to the assembly of test bars 6 of different diameters, making it convenient for the stamping machine 3 to stamp the test bar 6. It is highly versatile, flexible in operation, simple in structure, and highly safe. It can also be placed on a desktop for flexible use.

[0029] It should be emphasized that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
