Description

Technical Field

[0001] The utility model relates to the technical field of material processing, in particular to a double-sided convex dot forming device with an automatic straightening function. Background Art

[0002] Oil exploration torque sensors require bump welding on a specific steel strip with specific bumps. These bumps have a specific shape and size, and are evenly spaced at regular intervals (approximately 9mm, with a tolerance of no more than 1mm) across the strip.

[0003] The existing method for producing steel strips with raised dots involves first using a machining center to mill the steel sheets onto a workbench to create the raised dots and desired surface, and then using a laser to cut the strips into the desired shape. However, this method produces strips and raised dots with poor dimensional consistency, making it difficult to guarantee a satisfactory yield. Furthermore, the strips also produce large burrs, making deburring time-consuming.

[0004] The utility model patent with patent announcement number CN207204944U discloses a bump welding rolling device. The rolling device provided by the utility model has three deficiencies: 1. The power is rotated by a handwheel or an adjustable wrench, which has low work efficiency and consumes too much manpower; 2. There is no straightening device, and the steel strip will automatically curl after rolling, requiring manual straightening again, which consumes too much manpower; 3. The required bumps can only be formed by rolling on one side. The disadvantage of forming the bumps on one side is that the bumps need to be in contact with the other workpiece to be welded. After the current passes through, the bumps are melted to form a weld, but the back of the bumps on the steel strip needs to be in contact with the electrode for projection welding. However, the position of the bumps cannot be seen through the steel strip. To solve this problem, it is necessary to manually draw marking lines on the other side of the steel strip corresponding to the bumps so that the electrodes can be pressed on the bumps more accurately. Manual marking is time-consuming and labor-intensive. Taking the bump distance of about 9 mm in this example as an example, more than 110 marking lines need to be drawn on a 1-meter-long steel strip, which is very time-consuming and labor-intensive.

[0005] In order to solve the above-mentioned deficiencies, the utility model provides a double-sided convex dot forming device with a self-aligning function. Utility Model Content

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0035] Example

[0036] See also Figures 1 to 3 A double-sided convex dot forming device with a self-straightening function includes a base 1 and a steel strip rolling mechanism and a straightening component arranged on the base 1; the steel strip described in this embodiment refers to a specific convex dot steel strip that needs to be welded by convex dot welding on the oil exploration torque sensor. The convex dot steel strip has a specific size and shape, and convex dots of a certain shape and size need to be evenly distributed at a certain distance (about 9mm with a deviation of no more than 1mm) on the steel strip for welding.

[0037] Two positioning plates 2 are fixedly connected to the base 1 , and a rolling mechanism is provided between the two positioning plates 2 .

[0038] Specifically, the above-mentioned rolling mechanism includes an upper rolling roller 5, a lower rolling roller 6 and a coupling 7; wherein the two ends of the upper rolling roller 5 and the lower rolling roller 6 are respectively connected to the above-mentioned two positioning plates 2, a rolling channel is formed between the upper rolling roller 5 and the lower rolling roller 6, and the upper rolling roller 5 and the lower rolling roller 6 are connected through a transmission assembly.

[0039] See also Figures 4 to 7 In this embodiment, the transmission assembly includes square key 1 8, gear 1 9, square key 2 10 and gear 2 11; wherein square key 1 8 is connected to the upper rolling roller 5, and gear 1 9 is connected in coordination with square key 1 8; square key 2 10 is connected to the lower rolling roller 6, and gear 2 11 is connected in coordination with square key 2 10; gear 1 9 and gear 2 11 are meshed and connected; one end of the coupling 7 is connected to the lower rolling roller 6, and the other end is connected to the worm gear mechanism. In actual work, the worm gear mechanism drives the lower rolling roller 6 to rotate through the coupling 7, and the lower rolling roller 6 drives the upper rolling roller 5 to rotate through the above-mentioned transmission assembly, thereby realizing the rolling and output of the steel strip.

[0040] In order to enable gear 1 9 and gear 2 11 to drive the concave points on the upper rolling roller 5 and the lower rolling roller 6 to reach the same position synchronously when rotating synchronously, so that the upper rolling roller 5 and the lower rolling roller 6 can produce convex points at the same position on the steel belt when rolling the steel belt, the number of teeth z, the angle between the teeth θ and the angle ɑ from the center of the keyway to the center of the gear are further selected in this embodiment.

[0041] Specifically, Exemplarily, the number of teeth z of gear one 9 and gear two 11 is 24, the tooth space angle θ is 15°, and the angle ɑ between the center of the keyway and the center of the gear is 172.5°.

[0042] It can be seen that the angles between the centers of the two square keyways on gear one 9 and gear two 11 and the centers of the gears exactly differ by half a tooth. In this embodiment, the gears used have 24 teeth, and each tooth differs by 15° (=360°÷24). The angles between the centers of the two keyways and the centers of the gears are 172.5°, exactly differing by the angle of half a tooth, that is: 7.5° more than the distance of 11 teeth (11╳15°=165°) and 7.5° less than the distance of 12 teeth (12╳15°=180°). This is convenient for determining the angular relationship during assembly. Only when the angular relationship is correct can the positions of the convex points on both sides of the steel belt be consistent when rolling the steel belt.

[0043] In addition, please refer to Figures 5 to 7 , one set of the pits on the upper rolling roller 5 and the lower rolling roller 6 for rolling the steel belt to generate convex points must be angularly positioned the same as the installation position of the square key. When installing the gears, it must also be ensured that as Figure 5 shown, if the pit on the upper rolling roller 5 that is angularly positioned the same as the keyway faces the tooth of gear one 9, then the pit on the lower rolling roller 6 that is angularly positioned the same as the keyway faces the tooth groove of gear two 11. Two keyways are designed on the installation holes of the gears and the keyways differ by half a tooth pitch to facilitate determining the angular position during assembly, that is, as Figure 7 shown, the positions of the two keyways on the upper and lower gears of the keyway can exactly ensure that when the upper rolling roller 5 and the lower rolling roller 6 rotate synchronously with the gears, the pits on the upper rolling roller 5 and the lower rolling roller 6 reach the rolling position synchronously so that convex points are formed at the same positions on both sides of the steel belt to be rolled.

[0044] In order to eliminate the curling of the convex point steel belt after rolling, in this embodiment, a straightening assembly is further provided at the steel belt output end of the above rolling mechanism.

[0045] Specifically, the above straightening assembly includes a straightening pipe 4 and two support rods 3 respectively fixed at both ends of the straightening pipe 4. The support rod 3 is detachably connected to the base 1, so as to facilitate adjusting the relative position between the straightening pipe 4 and the rolling mechanism.

[0046] In this embodiment, after the steel belt is rolled and formed through the cavity between the upper rolling roller 5 and the lower rolling roller 6, it is straightened through the inner hole of the above straightening pipe 4.

[0047] During operation, the steel belt to be rolled is manually fed into the cavity between the upper rolling roller 5 and the lower rolling roller 6. Driven by the rotation of the upper rolling roller 5 and the lower rolling roller 6, the steel belt automatically advances, and after passing through the cavity between the upper rolling roller 5 and the lower rolling roller 6, it enters the straightening pipe 4 to complete straightening.

[0048] It should be noted that when the steel strip described in this embodiment is specifically used, it does not need to be curled and does not need to be very straight.

[0049] In addition, please refer to Figure 5 , only one annular groove of the upper rolling roller 5 and the lower rolling roller 6 can be used to roll the steel strip each time. When the annular groove is worn out and cannot be used, another annular groove needs to be used to roll the steel strip; at this time, the position of the support rod 3 needs to be adjusted so that the inner hole center of the straightening pipe 4 is located at the output end of the rolling mechanism again.

[0050] In order to ensure the fixed distance between the two positioning plates 2, in this embodiment, a plurality of spacer sleeves 12 are further provided between the two positioning plates 2; the spacer sleeves 12 are connected to the positioning plates 2 through a plurality of nuts 13.

[0051] In this embodiment, the sizes of the pits on the upper rolling roller 5 and the lower rolling roller 6 are different. Among them, in the illustrated example, the pit on the lower rolling roller 6 is larger, and the convex points rolled meet the requirements for the size of the convex points in the welding drawing. The pit on the upper rolling roller 5 is smaller, and the convex points rolled can be clearly seen visually and do not need to be too large. Their sizes can match the electrodes of the projection welding and can complete the welding.

[0052] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
