Description

The present invention relates to a work surface treatment apparatus and a work surface treatment method using the work surface treatment apparatus.

Cold forging, which is used as a manufacturing method for machine parts, has the disadvantage that the shape that can be manufactured is restricted compared to manufacturing by cutting, but there is almost no material loss and material costs can be significantly reduced. It has many merits such as short processing time, excellent mass productivity, and the ability to manufacture products with excellent strength and wear resistance.

By the way, when this cold forging is used, a lubricant is applied to the surface in order to improve the mold release of the forged member and prevent damage to the die and the forged member itself due to heat and contact pressure generated during processing. In many cases, a member to be forged that has been treated (bonded to form a lubricating film on the surface) is used.

Regarding this bonde treatment, the conventional treatment has a large number of treatment steps, which makes the treatment facility (equipment) large-scale, and further, it is extremely troublesome to treat the waste and contaminated waste liquid generated by the chemical reaction between the chemical and the work. It has various problems including environmental aspects, and in recent years, there has been an increase in demand for a coating type lubricant that lubricates the work surface by showering or dipping with a small environmental load.

However, if the coating amount of this coating type lubricant is too large, the molding die will be soiled, and if the coating amount is too small, a sufficient lubricating effect will not be obtained. Therefore, it is extremely important to control the coating amount. However, its management was very troublesome.

In order to solve such problems in the conventional treatment, the applicant proposes a work surface treatment apparatus disclosed in Japanese Patent No. 5523507 (hereinafter referred to as a conventional example) regarding the bonding treatment to the forged member. , We are trying to optimize the coating amount.

The work surface treatment apparatus disclosed in the prior art includes a slurry injection portion that injects a slurry, which is a mixture of liquid and abrasive grains, to the work (member to be forged), and lubricates the surface of the rotating work. The surface of the work is wet-blasted with the slurry ejected from this slurry injection part to remove stains such as oxide film and oil adhering to the surface of the work and the surface of this work. It is configured to form fine irregularities on the surface and perform pretreatment to improve the adhesion of the lubricant (lubricating film) to the surface of the work.

Japanese Patent No. 5523507

By the way, in the conventional example, a round gun type is adopted for the slurry injection part, and the slurry injected from this round gun type slurry injection part has a high injection pressure and a high impact pressure on the work. Depending on the work, the rotation of the work may be hindered.

If the injection pressure of the slurry is lowered so as not to hinder the rotation of the work, there is a problem that the wet blast treatment is insufficient and the adhesiveness (adhesion) of the lubricant is lowered, and the injection pressure of the slurry is lowered. If the transport speed is slowed down and the treatment time is lengthened in order to perform sufficient wet blasting treatment with a low exposure pressure, there arises a problem that the throughput is lowered and the processability is lowered.

Further, the slurry injected from this round gun type slurry injection unit has a circular injection region for the work. Therefore, as the work moves, the slurry hitting position moves from the upper side of the work to the lower side of the work. At a position deviated from the (work axis), the applied pressure may not be evenly applied to the end face of the work, and the work may tilt or fall, resulting in problems such as transfer trouble and uneven processing.

The present invention has been made in view of the current situation as described above, and surface treatment is applied to the work while stably transporting the work without hindering the rotation of the work or tilting or tilting the work.

It is said to be composed.

More specifically, the pinching moving unit 4 of the present embodiment is configured to convey the work W while sequentially repeating the following operations (a) to (f) (see FIGS. 5 and 6).

(A) When the work W is loaded from the work loading unit 7 to the work transport unit 1, the substrate 4a (upper side in the figure) moves inward and is between the projecting body 5a of the substrate 4a and the moving claw 6a. Work W is placed.

The moving claw 6a moves closer to the projecting body 5a to sandwich the work W, and the base 4b (lower side in the figure) moves the second base portion 13b to the work W in the transport direction (hereinafter, work transport direction). The moving claw 6b is moved away from the projecting body 5b and moved outward while widening the distance between the projecting body 5b and the moving claw 6b.

(C) The substrate 4a holding the work W moves in the work transfer direction to move the work W by a predetermined distance, and at the same time, the substrate 4b moves in the opposite direction of the work transfer, and then the work is transferred from the work loading section 7.

(F) The substrate 4b holding each work W moves in the work transfer direction to move each work W by a predetermined distance, and at the same time, the substrate 4a moves in the work transfer reverse direction, and then from the work loading section 7. A new work W is put into the work transfer unit 1 again.

That is, as shown in FIGS. 7 (a) to 7 (h), for example, the pinching and moving unit 4 of the present embodiment bases the movement of the work W1 initially loaded from the first transport position to the second transport position. When 4a is performed, the base 4b performs the movement of the work W1 from the second transfer position to the third transfer position and the subsequent transfer of the loaded work W2 from the first transfer position to the second transfer position, and then While the substrate 4b is transporting the works W1 and W2, the substrate 4a returns and moves, the transfer charge is switched to the substrate 4a, the work W1 is moved from the third transport position to the fourth transport position, and the work W2 is the first. 2 The transfer from the transfer position to the third transfer position and the movement of the work W3 loaded next from the first transfer position to the second transfer position are performed by the substrate 4a, and when the next work W4 is further loaded, the work W4 is moved again. The transfer charge is switched to the substrate 4b, the work W1 is moved from the 4th transfer position to the 5th transfer position, the work W2 is moved from the 3rd transfer position to the 4th transfer position, and the work W3 is moved from the 2nd transfer position to the 5th transfer position. 3 The substrate 4a and the substrate 4b alternately move the work W to a predetermined amount, such that the substrate 4b performs the movement to the transfer position and the transfer of the work W4 loaded next from the first transfer position to the second transfer position. It is configured to be transported linearly one by one.

In this embodiment, when the work W is sandwiched between the projecting bodies 5a and 5b and the moving claws 6a and 6b, the pinching is not limited to holding the work W in a contact state that does not hinder the rotation of the work W. This includes the case where the 5a, 5b and the moving claws 6a, 6b are in a non-contact state with a slight clearance with respect to the work W.

Further, the wet blast processing unit 8 is provided in a continuous state on the upstream side of the work transfer unit 1 described above, specifically, on the downstream side of the work loading unit 7, and is rotationally conveyed by the work transfer unit 1. A slurry injection unit 2 for injecting a slurry to the next work W is provided, and the surface of the work W is wet-blasted with the slurry injected from the slurry injection unit 2.

Specifically, as shown in FIG. 1, the wet blast processing unit 8 of the present embodiment is provided on the pair of slurry injection units 2 provided on the upper side of the work transfer unit 1 and on the lower side of the work transfer unit 1. A slurry recovery tank section 14 for collecting and storing the slurry injected from the slurry injection section 2 and a pump 15 for supplying the slurry collected in the slurry recovery tank section 14 to the slurry injection section 2 again are provided. ing.

More specifically, a slit nozzle type (so-called wide gun) in which the slurry injection port portion into which the slurry is ejected is formed in a slit shape is adopted for each slurry injection portion 2, and as shown in FIG. 1, The work W is arranged in parallel along the transport direction, in other words, it is provided in a parallel state with an interval in the work transport direction.

More specifically, each slurry injection unit 2 of this embodiment has substantially the same structure as the nozzle body disclosed in Japanese Patent Application Laid-Open No. 2001-300363, and each slurry injection unit 2 is a slurry. The slit width of the ejection port (width in the lateral direction of the slurry ejection port) is set to a dimension narrower than the facing distance between the pair of rotating rollers 3a of the work transport section 1 described above, and the slurry ejection port is also set. As shown in FIG. 8 (b), the slit length (length in the longitudinal direction of the slurry injection port portion) is a plurality of work Ws in the process of being transported, specifically, in the present embodiment, five continuous bodies. The length is set so that the slurry can be simultaneously injected (fired) on the work W.

Further, in the slurry injection portion 2 located on the upstream side in the transport direction of the work W, the longitudinal direction of the slurry injection port portion is directed to the transport direction of the work W and 25 ° to 35 ° with respect to the work rotation axis (this implementation). In the example, it is provided in an ascending and inclined state in the work transport direction at an angle of 30 °), and a linear slurry (thin inclined band-shaped slurry) extending in the vertical direction (vertical direction) from the back surface side of the work is injected to the work W. In the slurry injection section 2 located on the downstream side in the transport direction of the work W, the longitudinal direction of the slurry injection port is directed to the transport direction of the work W and 25 ° to 35 ° with respect to the work rotation axis.

That is, in the slurry injection section 2 of the present embodiment, due to the above configuration, the opening area of the slurry injection port portion is widened as compared with the conventional round gun type, whereby the injection pressure is lowered and the impact pressure on the work W is increased. It is lowered to reduce the rotation inhibition of the work W due to the irradiation pressure of the slurry, and the slurry injected from the slurry injection unit 2 passes through the center of the end face of the work W and crosses the end face of the work W in the vertical direction. It is hit in a straight line, and as a result, the hit pressure is applied to the end face of the work W in a well-balanced manner (uniformly), and the balance of the work W that occurs in the case of the conventional round gun type is lost. The work W is configured so that the wet blasting process is surely performed without causing problems such as the work W to fall down, to stably convey the work W, and to cause problems such as transfer trouble and processing unevenness.

Further, as shown in FIG. 8A, the slurry injected from the slurry injection unit 2 is not hit by the rotary roller 3a, the premature wear of the rotary roller 3a due to the slurry is prevented, and further, with respect to the integrated work W. The amount of slurry shot is increased compared to the case of the round gun type (wet blast processing time is longer), which increases the opening area of the slurry injection port and the slurry injection pressure compared to the conventional round gun type. Even if the pressure applied to the work W is reduced, the wet blasting process can be performed in a predetermined amount without taking measures such as reducing the transport speed to slow down the processing time, resulting in insufficient wet blasting process. It is configured to ensure proper wet blasting without causing problems such as a decrease in throughput.

The type of slurry (abrasive grain material, abrasive particle size, etc.) used for the wet blasting in the wet blasting unit 8 shall be an appropriate one depending on the material of the work W, etc., but in this embodiment, it is assumed that an appropriate one is adopted. The liquid (water) and the average particle size used in the surface treatment method of the forged member disclosed in Japanese Patent No. 6101668 so that the wet blast treatment suitable for the surface treatment of the work W made of steel material is performed, have an average particle size of about.
