Description

Technical Field

[0001] The invention relates to a hand wheel and a method for processing anti-skid patterns on the hand wheel, namely a novel anti-skid hand wheel and a method for processing the anti-skid patterns. Background Art

[0002] At present, the anti-skid handwheel used for opening and closing right-angle valves or faucets is usually processed with a knurling process to produce anti-skid patterns, and the anti-skid patterns that can be processed by the knurling process are mainly straight patterns or mesh patterns. However, the wall thickness of the anti-skid handwheel of the right-angle valve and faucet is generally 1.5mm ~ 2mm. Due to the thin thickness, it cannot be directly knurled, and it is often necessary to use a lining clamp block to perform knurling. At the same time, due to the use function and material saving of the anti-skid handwheel of the right-angle valve and faucet, the internal structure of the handwheel is also relatively complex, which makes it quite difficult to process the lining clamp block. In this way, the conventional straight or mesh anti-skid pattern processing not only requires the use of a knurling machine, but also requires the production of a special lining clamp block according to the internal structure of the handwheel. Obviously, the processing is quite troublesome and reduces the application value. In addition, the anti-skid patterns such as straight or mesh patterns processed by the knurling process often have a weak three-dimensional sense of protrusion, which not only affects the appearance, reduces the comfort of the friction feel, but also affects the anti-skid effect. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a new type of anti-skid handwheel and anti-skid pattern processing method which is simple to process, has high application value, strong convex three-dimensional sense, beautiful appearance, comfortable friction feel and reliable anti-skid effect.

[0004] The technical problem of the present invention is achieved through the following technical solutions:

[0005] A novel anti-skid handwheel comprises a cylindrical body, wherein the outer circumferential surface of the body is provided with a plurality of anti-skid convex rings surrounding the circumference, the plurality of anti-skid convex rings are parallel to each other and arranged along the upper and lower sides, each anti-skid convex ring is formed by a plurality of anti-skid convex rings connected in sequence along the circumference end to end, and a spacing groove is provided between each two adjacent anti-skid convex rings.

[0006] Each of the anti-skid protrusions is a granular protrusion in the shape of a regular quadrangular pyramid, and a plurality of anti-skid protrusions cooperate with a plurality of spacing grooves to form a spline-tooth-shaped anti-skid pattern.

[0007] The bottom surface of each anti-skid protrusion is a square with a side length of 0.5mm to 2mm, and the root angle of each anti-skid protrusion in the longitudinal projection is 60° to 90°.

[0008] The depth of each spacing groove is 0.5mm ~ 2mm, and the width of each spacing groove is 0.5mm ~ 2mm.

[0009] The spacing groove is a triangular groove.

[0010] The anti-skid convex rings are provided in 5 to 20 rows, and the anti-skid convexities are provided in total in 60 to 120 numbers.

[0011] A novel method for processing anti-skid patterns of an anti-skid handwheel, the processing method comprising the following steps:

[0012] Step 1: Select a cylindrical handwheel blank, and complete the internal matching structure and outer circumferential surface processing of the handwheel blank;

[0013] Step 2: Processing a processing surface with a depth of 0.5 mm to 2 mm on the outer circumferential surface of the lower end of the handwheel blank;

[0014] Step 3: Processing a ring groove with a depth of 0.5mm to 2mm and a width of 0.5mm to 2mm on the outer circumferential surface of the upper end of the handwheel blank;

[0015] Step 4, repeat the processing of step 3 to continue processing a plurality of annular grooves, and make each annular groove parallel to each other, until all the annular grooves are processed on the outer circumferential surface of the upper end of the handwheel blank, and a convex ring is formed between each two adjacent annular grooves;

[0016] Step 5. Use a spline external tooth punch with a tooth root angle of 60°~90° and 60~120 teeth to roll the outer circumferential surface of the upper end of the handwheel blank with a ring groove, and process each convex ring into an anti-slip convex ring, so that anti-slip patterns are formed on the outer circumferential surface of the upper end of the entire handwheel blank.

[0017] Compared with the prior art, the present invention mainly provides a plurality of circumferential anti-skid convex rings on the outer circumferential surface of the main body, and the plurality of anti-skid convex rings are parallel to each other and arranged along the upper and lower parts, and each anti-skid convex ring is composed of a plurality of anti-skid convex rings connected in sequence along the circumference and surrounding each other end to end, and a spacing groove is provided between each adjacent two anti-skid convex rings; therefore, a plurality of anti-skid convex rings and a plurality of spacing grooves can together constitute a novel and unique spline tooth anti-skid pattern, which not only has a stronger raised three-dimensional sense and a more comfortable friction feel, but also has a beautiful appearance and a very reliable anti-skid effect; at the same time, the anti-skid pattern is formed by an original spline external tooth punching die, and compared with the anti-skid patterns such as straight lines or mesh lines processed by conventional knurling technology, it not only greatly reduces the trouble of making a special lining clamp according to the internal structure of the handwheel, but also does not require the use of special processing equipment, so the processing process is simpler and the application value is higher.

[0031] A novel anti-skid handwheel and a processing method for anti-skid patterns mainly refer to designing anti-skid patterns with unique structures on the anti-skid handwheel and a processing method for the anti-skid patterns. The anti-skid handwheel is mainly used for opening and closing right-angle valves or faucets.

[0032] The anti-skid hand wheel has a cylindrical body 1, and the anti-skid pattern 2 is designed on the outer circumference of the body 1. The specific structure is as follows: Figure 1 , Figure 2 , Figure 4As shown: a plurality of circumferentially encircling anti-skid convex rings 21 are provided on the outer circumferential surface of the main body 1, and the plurality of anti-skid convex rings are parallel to each other and are arranged on the outer circumferential surface of the main body 1 along the upper and lower sides. Each anti-skid convex ring 21 is composed of a plurality of anti-skid convexities 211 connected in sequence along the circumference and encircled end to end, and a spacing groove 22 is provided between each adjacent two anti-skid convexities 211; in this way, a plurality of anti-skid convexities 211 and a plurality of spacing grooves 22 can together form a spline-toothed anti-skid pattern 2.

[0033] Moreover, each anti-skid protrusion 211 is as Figure 5 The granular projections are shown as regular quadrangular pyramidal shaped, and the bottom surface of each anti-skid projection 211 is a square with a side length of 0.5mm~2mm, and the root angle of each anti-skid projection 211 in the longitudinal projection is 60°~90°.

[0034] Each of the spacing grooves 22 is as follows Figure 3 The triangular grooves shown have a groove depth of 0.5mm ~ 2mm and a groove width of 0.5mm ~ 2mm.

[0035] Typically, the anti-skid protrusions 21 on an anti-skid hand wheel are provided with 5 to 20 rows, and the anti-skid protrusions 211 are provided with 60 to 120 in total.

[0036] At the same time, the anti-slip pattern processing method of the new anti-slip handwheel is mainly as follows Figure 6 to Figure 11 As shown, the specific steps include:

[0037] Step 1: Select a cylindrical handwheel blank 11, and complete the internal matching structure and outer circumferential surface processing of the handwheel on the handwheel blank;

[0038] Step 2: machining a machining surface 111 with a depth of 0.5 mm to 2 mm on the outer circumferential surface of the lower end of the handwheel blank 11;

[0039] Step 3: machining an annular groove 23 with a depth of 0.5 mm to 2 mm and a width of 0.5 mm to 2 mm on the outer circumferential surface of the upper end of the handwheel blank 11;

[0040] Step 4, repeat the processing of step 3 to continue processing a plurality of annular grooves 23, and make each annular groove parallel to each other, until all the annular grooves 23 are processed on the outer circumferential surface of the upper end of the handwheel blank 11, and a convex ring 24 is formed between each two adjacent annular grooves 23;

[0041] Step 5: Use a spline external tooth punch with a root angle of 60°~90° and 60~120 teeth to roll the outer circumferential surface of the upper end of the handwheel blank 11 with the ring groove 23, and process each convex ring 24 into an anti-slip convex ring 21, so that the anti-slip pattern 2 is formed on the outer circumferential surface of the upper end of the entire handwheel blank 11.

[0042] The anti-skid pattern of the present invention is novel and unique, not only has a stronger convex three-dimensional sense and a more comfortable friction feel, but also has a beautiful appearance and a very reliable anti-skid effect.

[0043] In addition, the anti-slip pattern is made of an original spline external tooth die. Compared with the anti-slip patterns such as straight or mesh patterns made by conventional knurling technology, it can be processed by ordinary lathes and punching machines. It not only greatly reduces the trouble of making special lining blocks according to the internal structure of the handwheel, but also does not require the use of special processing equipment, making the processing process simpler and the application value higher.
