Carburizing and quenching are common heat treatment processes for metal materials, and can ensure that the surface of a workpiece which is carburized by carbon obtains high hardness and improve the wear resistance of the workpiece. Tempering is a metal heat treatment process in which the quenched workpiece is reheated to a temperature below the lower critical temperature Ac1 (the starting temperature of pearlite transformation to austenite during heating), and cooled in a medium such as air, water, oil, or the like after holding for a certain period of time. Are generally used to reduce or eliminate internal stresses in quenched steel parts or to reduce their hardness and strength to improve their ductility or toughness. The quenched workpiece should be tempered in time, and the required mechanical properties can be obtained through the matching of quenching and tempering.

Example 1

Referring to fig. 1, 2, 3 and 4, fig. 1 is a schematic structural view of a straight shaft positioning tool 100, fig. 2 is a schematic structural view of a supporting plate 110, fig. 3 is a schematic structural view of a supporting member 150, and fig. 4 is a partially enlarged view of a position iv in fig. 1. The embodiment of the invention provides a straight shaft positioning tool 100 which is used for filling 300 straight shaft workpieces such as a straight shaft and the like so as to carry out heat treatment on the workpieces. The straight shaft positioning tool 100 mainly comprises: a pallet 110, a fixing post 130, and a support 150.

The supporting plate 110, a plurality of connecting posts 111 are fixedly arranged on the supporting plate 110, and the top ends of the connecting posts 111 protrude out of the upper side of the supporting plate 110.

The fixing posts 130 (6 are shown in fig. 1) are sleeved in the connecting posts 111, and the fixing posts 130 can be fixed to the connecting posts 111 (8). The arrangement of the plurality of connecting columns 111 facilitates the installation and fixation of the plurality of fixing columns 130.

It should be noted that the fixing post 130 may be connected to the connecting post 111 by a screw connection or the like, or may be mounted on a component having a structure capable of being connected to the fixing post 130 in a matching manner (for example, refer to a corresponding manner in which the flag pole is mounted on the bottom surface), so as to fix the fixing post 130.

The supporting member 150 is formed with a plurality of first positioning holes 151 (8) matching with the fixing posts 130. The supporting member 150 is connected to the fixing post 130 through the first positioning hole 151. The supporting member 150 is provided with a through hole 153 matching with the straight shaft 300, and the straight shaft 300 is sleeved with the through hole 153. The through holes 153 play a limiting role for the straight shaft 300. The cooperative engagement of the plate 110 and the support 150 enables the axis of the straight shaft 300 to be parallel to the axis of the through hole 153 (even if the straight shaft 300 remains vertical). The user can install the fixing post 130 in the connecting post 111, install the supporting member 150 on the fixing post 130 through the first positioning hole 151 (at this time, the upper side of the connecting post 111 can abut against the lower side of the supporting member 150), and then put one end of the straight shaft 300 on the supporting plate 110 through the through hole 153, so that the straight shaft 300 can be kept vertical, and the thermal treatment deformation of the straight shaft 300 is reduced.

Further, the supporting plate 110, the fixing posts 130 and the supporting members 150 may be made of heat-resistant metal materials, so that the straight shaft positioning tool 100 can work more reliably.

Referring to fig. 1 and 4, the fixing column 130 may further be sleeved with a bushing 170 matching with the height of the straight shaft 300, and the two supporting members 150 are respectively located at two ends of the bushing 170. The provision of the bushing 170 and the two supports 150 enables the two supports 150 to better support the straight shaft 300 when the straight shaft 300 is long, so that the straight shaft 300 can be always kept in a vertical state.

It should be noted that, as shown in fig. 1 and fig. 4, in use, a user may increase the height of the fixing column 130 appropriately, so that the straight shaft positioning tool 100 can achieve multi-layer installation: after the two supports 150 are respectively installed at the two ends of the bushing 170, the user can put one end of the first straight shaft 300 on the supporting plate 110 through the through holes 153 on the two supports 150, thereby forming a first layer of filling of the straight shaft 300; another supporting plate 110 and a supporting piece 150 are sequentially arranged on the fixed column 130, and then a bushing 170 is sleeved on the fixed column 130; and then a supporting piece 150 is arranged on the fixed column 130, and then the second group of straight shafts 300 are placed, so that the second layer of straight shafts 300 can be filled. The user can select a suitable assembling mode according to the self requirement, and the heat treatment efficiency of the straight shaft 300 can be effectively improved by using the straight shaft positioning tool 100.

The upper side or the lower side of the supporting plate 110 may be provided with a plurality of storage slots 113 matched with the straight shaft 300. The storage groove 113 may be designed according to the size of the straight shaft 300, and the straight shaft 300 may be vertically placed in the storage groove 113. The tip of the straight shaft 300 may abut against the bottom of the storage groove 113 of the adjacent pallet 110. The arrangement of the storage slot 113 not only can enable the straight shaft 300 to be fixed better by the straight shaft positioning tool 100, but also can prevent the straight shaft 300 from falling off after penetrating through the supporting plate 110.

Referring to fig. 1 and 4, the connecting column 111 may be a hollow cavity with openings at two ends, the supporting plate 110 may be fixedly connected to the outer side of the connecting column 111, the straight shaft positioning tool 100 further includes a furnace material tray 190, the furnace material tray 190 is provided with a plurality of second positioning holes (not shown in the figure, the second positioning holes are shielded by the connecting column 111 in fig. 4) matched with the fixing columns 130, and the fixing columns 130 penetrate through the connecting column 111 and are sleeved with the second positioning holes. The connecting column 111 is connected with the second positioning hole through the fixing column 130, so that the straight shaft positioning tool 100 can be assembled on the furnace tray 190 for use, and the straight shaft positioning tool 100 can move conveniently during heat treatment. The user can insert the fixing post 130 into the second positioning hole, sequentially mount the supporting plate 110 and the supporting member 150 on the fixing post 130 (the supporting plate 110 can prevent the straight shaft 300 from falling off the burden tray 190), mount the bushing 170 on the fixing post 130, and mount the supporting member 150 on the fixing post 130, so as to place the straight shaft 300 in the through hole 153.

The number of the connecting columns 111 can be 8, and the connecting columns are arranged at the edge of the supporting plate 110 at intervals in the circumferential direction. The 8 fixing posts 130 may be respectively mounted on the corresponding connecting posts 111 to facilitate the fixing of the supporting plate 110.

The number of the through holes 153 on each support member 150 may be 300-400 (for example, 375). The straight shaft positioning tool 100 can simultaneously load a plurality of straight shafts 300, so that the production efficiency of the straight shafts 300 is improved.

The supporting member 150 is a net shape and may be woven by using a heat-resistant steel wire 155 having a diameter of 4 mm. The net-shaped supporting member 150 has a light weight, which is beneficial to the light weight design of the straight shaft positioning tool 100.

The edges of the supporter 150 may be reinforced with heat-resistant steel wires having a diameter of 6mm to improve reliability in use of the supporter 150.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
