Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel processing equipment, specifically to a rust-proof spraying device for processing stainless steel bars. Background Technology

[0002] After the stainless steel bars are processed, an anti-rust spray coating is applied to the outside of the bars to improve their overall rust resistance and extend their service life.

[0003] For example, the utility model patent disclosed in publication number CN221208592U discloses a rust-proof spraying device for processing stainless steel bars. This rust-proof spraying device for processing stainless steel bars includes a housing, an inclined platform connected to the housing, and a motor connected inside the inclined platform. A rotating block is fixedly connected to the output end of the motor. A moving groove is opened at the bottom of the rotating block. A main piston is slidably connected in the moving groove. A pressure rod passing through the top surface of the moving groove is fixedly connected to the surface of the main piston. A sliding groove is opened at the end of the guide groove. A secondary piston is slidably connected in the sliding groove. A push rod is fixedly connected to one side of the secondary piston. A pressure plate is fixedly connected to one end of the push rod. This utility model sets a pressure rod on the main piston and a pressure plate on the push rod. By utilizing the cooperation between the pressure rod and the pressure plate, the pressure plate can clamp and fix the raw material bar, thereby ensuring that the raw material bar can be driven by the motor to rotate and spray stably, improving the spraying uniformity of the raw material bar.

[0004] Although the above-mentioned equipment can perform spraying operations on stainless steel bars, it is not convenient to perform uniform spraying operations on batches of stainless steel bars. At the same time, the uniformity of spraying on the side of the bars is also insufficient. Therefore, there is an urgent need for a rust-proof spraying device for stainless steel bar processing to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a rust-proof spraying device for processing stainless steel bars, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rust-preventive spraying device for processing stainless steel bars, comprising a spraying device for support and spraying.

[0007] The limiting device has two sets, and both sets of the limiting device are rotatably locked at the middle of the inner end face of the spraying device. Four sets of stainless steel bars are equidistantly locked at the inner end faces of the two sets of the limiting device. The limiting device is used to limit and guide the stainless steel bars.

[0008] A transmission gear ring is fixedly disposed at the center of the side end face of one of the limiting devices. A servo motor is disposed on the side end face of the spraying device near the transmission gear ring, and a transmission gear is disposed at the output end of the servo motor.

[0009] Preferably, the spraying device includes a support bracket, a spraying tube is provided on the inner end face of the support bracket near the middle, and two sets of fixed guide tubes are fixedly connected to the top of the support bracket, with spraying heads fixedly provided on the lower end faces of the two sets of fixed guide tubes.

[0010] Preferably, the limiting device includes a positioning turntable, a limiting seat is provided at the center of the rear end face of the positioning turntable, and four sets of alignment seats are equidistantly arranged on the side end face of the positioning turntable. A pen-shaped cylinder is fixedly arranged at the center of the upper end face of the alignment seat, and a pressing clamp is fixedly arranged at the output end of the pen-shaped cylinder. Four sets of fixing slots are equidistantly opened on the side end face of the positioning turntable opposite the pen-shaped cylinder.

[0011] Preferably, the inner end face of the limiting rotary seat is fitted and connected to the outside of the spraying tube, the transmission gear ring is meshed with the transmission gear, and the limiting rotary seat is fitted to the outside of the pressing fixture. This facilitates the provision of sufficient guiding space for the spraying tube when the subsequent positioning turntable rotates, and also facilitates the subsequent external feeding pipe to provide raw materials to the inside of the spraying tube.

[0012] Preferably, the side of the pressing clamp is fitted and connected to the inner end face of the alignment card seat, and the pen-shaped cylinder drives the pressing clamp to slide up and down inside the alignment card seat. The fitted connection between the pressing clamp and the alignment card seat allows the alignment card seat to limit the side of the pressing clamp, thereby improving the stability of the subsequent up and down sliding of the pressing clamp inside the alignment card seat.

[0013] Preferably, the positioning turntable is rotatably engaged with the inner end face of the support bracket via the limiting rotating seat. The pressing clamp and the fixing slot are coaxially aligned. The limiting rotating seat provides sufficient limiting foundation for the positioning turntable, thereby improving the stability of the subsequent rotation of the positioning turntable inside the support bracket. At the same time, the coaxial alignment of the pressing clamp and the fixing slot facilitates the subsequent locking operation of the fixed slot on the positioned stainless steel bar.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting up a spraying device and a limiting device, allows four sets of stainless steel bars to be detachably clamped into four sets of fixed slots by a pressing clamp, thereby facilitating the rapid and stable feeding and unloading of batches of stainless steel bars. At the same time, the spraying head and spraying tube can cooperate with two sets of cyclically rotating positioning turntables to perform all-round spraying operations on the inside and outside of the four sets of stainless steel bars, effectively improving the efficiency and uniformity of the equipment for rust prevention spraying of batches of stainless steel bars.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 One embodiment of this utility model is a rust-preventive spraying device for processing stainless steel bars, comprising a spraying device 2 for support and spraying.

[0023] The limiting device 3 has two sets, and both sets of the limiting device 3 are rotatably locked in the middle of the inner end face of the spraying device 2. Four sets of stainless steel rods 4 are equidistantly locked in the inner end face of the two sets of limiting devices 3. The limiting device 3 is used to limit and guide the stainless steel rods 4.

[0024] A transmission gear ring 5 is fixedly installed at the center of the side end face of one of the limiting devices 3. A servo motor 1 is installed on the side end face of the spraying device 2 near the transmission gear ring 5. A transmission gear 6 is installed at the output end of the servo motor 1.

[0025] The spraying device 2 includes a support bracket 23. A spraying tube 24 is provided on the inner end face of the support bracket 23 near the middle. Two sets of fixed guide tubes 22 are fixedly connected to the top of the support bracket 23. Spraying heads 21 are fixedly provided on the lower end face of the two sets of fixed guide tubes 22.

[0026] The limiting device 3 includes a positioning turntable 32. A limiting seat 36 is provided at the center of the rear end face of the positioning turntable 32. Four sets of alignment seats 31 are equidistantly arranged on the side end face of the positioning turntable 32. A pen-shaped cylinder 33 is fixedly arranged at the center of the upper end face of the alignment seat 31. A pressing clamp 34 is fixedly arranged at the output end of the pen-shaped cylinder 33. Four sets of fixing slots 35 are equidistantly opened on the side end face of the positioning turntable 32 opposite to the pen-shaped cylinder 33.

[0027] The inner end face of the limiting rotary seat 36 is fitted and connected to the outside of the spraying tube 24, the transmission gear ring 5 is meshed with the transmission gear 6, and the limiting rotary seat 36 is fitted to the outside of the pressing fixture 34. This allows the positioning turntable 32 to provide sufficient guiding space for the spraying tube 24 when it rotates, and also facilitates the external feeding pipe to supply raw materials to the inside of the spraying tube 24.

[0028] The side of the pressing clamp 34 is fitted and connected to the inner end face of the alignment card seat 31, and the pen-shaped cylinder 33 drives the pressing clamp 34 to slide up and down inside the alignment card seat 31. The fitted connection between the pressing clamp 34 and the alignment card seat 31 allows the alignment card seat 31 to limit the side of the pressing clamp 34, thereby improving the stability of the subsequent up and down sliding of the pressing clamp 34 inside the alignment card seat 31.

[0029] The positioning turntable 32 is rotatably engaged with the inner end face of the support base 23 via the limiting turntable 36. The pressing clamp 34 and the fixing slot 35 are coaxially aligned. The limiting turntable 36 can provide sufficient limiting base for the positioning turntable 32, thereby improving the stability of the subsequent rotation of the positioning turntable 32 inside the support base 23. At the same time, the pressing clamp 34 and the fixing slot 35 are coaxially aligned, which facilitates the subsequent locking operation of the fixed slot 35 on the positioned stainless steel bar 4.

[0030] Working principle: When feeding stainless steel bars 4, the operator can activate the two uppermost pen-shaped cylinders 33 via the external control panel. The pen-shaped cylinders 33 then lift the pressing clamp 34, guiding the stainless steel bars 4 into the fixing slots 35 of the two positioning turntables 32. After positioning the stainless steel bars 4, the operator can activate the two pen-shaped cylinders 33 again. This time, the two pen-shaped cylinders 33 lock the fed stainless steel bars 4 in place via the pressing clamp 34. Then, the servo motor 1 starts, and through the meshing of the transmission gear 6 and the transmission ring 5, the servo motor 1 drives the limit device 3 to rotate 90 degrees until all four stainless steel bars are fed into place. After material 4 is loaded, before spraying, the operator can connect the anti-rust spray liquid supply pipe to the side of the spraying tube 24 and the two sets of fixed guide tubes 22 respectively to facilitate the subsequent supply of high-pressure anti-rust spray liquid. During spraying, the operator can continuously drive the transmission gear ring 5 and the two sets of limit devices 3 to rotate through the servo motor 1 and the transmission gear 6, so that the four sets of stainless steel rods 4 can rotate circumferentially around the spraying tube 24. The spraying tube 24 and the spraying head 21 can spray the outside of the rotating stainless steel rods 4 in all directions. After the spraying is completed, the operator can repeat the above loading steps, remove the stainless steel rods 4 and reload them.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
