Description

Technical Field

[0001] The utility model belongs to the technical field of fixing long stock pipes, and specifically relates to a fixing tooling for chemical oxidation of long stock pipes. Background Art

[0002] When the long stock pipes in the current workshop are chemically oxidized, usually aluminum wires are manually used to tie the two ends and the middle part of the aluminum pipes, and then chemical oxidation treatment is carried out. However, this process is time-consuming and laborious, and multiple operators are required to cooperate to tie the pipes, increasing the labor cost. Moreover, during the tying process, several turns of aluminum wires are wound around the middle part of the pipes to ensure the tying firmness. However, it is found that after the long stock pipes are chemically oxidized, the parts tied by aluminum wires in the middle are prone to residual oxidation color and unevenness, resulting in a relatively low yield of long stock pipes (the primary yield is about 80% or so), and operators need to carry out separate rework treatment, increasing the processing cost.

[0003] Therefore, there is an urgent need to design a fixing tooling for long stock pipes that does not require aluminum wire fixation. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fixing tooling for chemical oxidation of long stock pipes. Through the design of a cross bar, a first U-shaped frame, a second U-shaped frame and a pressing plate assembly, the rapid loading requirements and chemical oxidation conditions of long stock pipes with different lengths can be met, the application range is wide, and a single operator can also complete the loading of long stock pipes, greatly reducing the labor cost, solving the problem of uneven oxidation caused by tying the middle part of long stock pipes with aluminum wires, reducing the product rejection rate and rework rate, and improving the production flow speed and the yield of long stock pipes.

[0005] To solve the above technical problems, the utility model provides a fixing tooling for chemical oxidation of long stock pipes, which includes a cross bar, a first U-shaped frame, a second U-shaped frame and a pressing plate assembly. The first U-shaped frame and the second U-shaped frame are fixedly arranged at both ends of the cross bar. Installation cavities are arranged inside both the first U-shaped frame and the second U-shaped frame. Pad strips for spacing and supporting several layers of long stock pipes are arranged inside the installation cavities of the first U-shaped frame and the second U-shaped frame.

[0006] There are two groups of the pressing plate assemblies, which are respectively arranged on the inner sides above the first U-shaped frame and the second U-shaped frame. Each group of the pressing plate assemblies includes a threaded sleeve, a threaded rod and a pressing plate. The threaded sleeve is located above the installation cavity, and its upper end is fixed to the first U-shaped frame or the second U-shaped frame through a fastener. The lower end is sleeved outside the upper end of the threaded rod and is threadedly connected with it. The lower end of the threaded rod is fixed to the pressing plate, and the pressing plate is used to press the topmost layer of long stock pipes.

[0007] Further, the pressing plate is triangular, and its two ends are located in the installation cavity and are slidably connected to its side walls.

[0008] Further, several reinforcing ribs are provided on the inner side of the pressing plate.

[0009] Further, the end of each long material pipe exceeds the outside of the cushion bar corresponding to its height, and the exceeding distance ≥ 5 mm.

[0010] Further, the distance between two adjacent long material pipes in each layer ≥ 5 mm.

[0011] Further, the width of the cushion bar is smaller than the width of the installation cavity.

[0012] Further, both the first U-shaped frame and the second U-shaped frame include an inverted funnel-shaped section and a U-shaped section integrally formed from top to bottom. The threaded sleeve is fixed inside the inverted funnel-shaped section, and the cushion bar is arranged inside the U-shaped section.

[0013] Further, the fastener is a bolt.

[0014] Further, a cushion plate is provided between the pressing plate and the long material pipe at the topmost layer.

[0017] 2. Through the triangular pressing plate structure and the design of the reinforcing ribs, the pressing force of the pressing plate when pressing down is more stable, which is convenient for fixing the long material pipe and not easy to move, and improves the stability of the long material pipe during the chemical oxidation process.

[0018] 3. Through the design of the cushion bar, the present utility model can prevent the long material pipes in the upper and lower layers from moving, improve the stability of multiple layers of long material pipes during the oxidation process, and each layer of long material pipes is laid flat on the corresponding cushion bar.

Detailed Embodiment

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0025] In a specific embodiment of the present utility model, as Figure 1-2 shown, a fixing tooling for chemical oxidation of long material pipes includes a cross bar 1, a first U-shaped frame 2, a second U-shaped frame 3 and a pressing plate assembly 4. The first U-shaped frame 2 and the second U-shaped frame 3 are fixedly arranged at both ends of the cross bar 1. Installation cavities are provided in both the first U-shaped frame 2 and the second U-shaped frame 3, and cushion strips 5 for spacing and supporting several layers of long material pipes 100 are provided in the installation cavities of the first U-shaped frame 2 and the second U-shaped frame 3;

[0026] The pressing plate assembly 4 has two groups and is respectively arranged on the inner sides above the first U-shaped frame 2 and the second U-shaped frame 3. Each pressing plate assembly 4 includes a threaded sleeve 41, a threaded rod 42 and a pressing plate 43. The threaded sleeve 41 is located above the installation cavity, and its upper end is fixed to the first U-shaped frame 2 or the second U-shaped frame 3 through a fastener. The lower end is sleeved on the outer side of the upper end of the threaded rod 42 and is threadedly connected thereto. The lower end of the threaded rod 42 is fixed to the pressing plate 43, and the pressing plate 43 is used to press the topmost long material pipe 100. In this embodiment, the fastener is a bolt 6, and a plurality of locking holes with different heights are provided on the threaded sleeve 41 for locking and fixing according to requirements. Of course, in other embodiments, scales can be provided on the outer side walls of the first U-shaped frame 2 or the second U-shaped frame 3 to facilitate reading the height of the long material pipe 100 during loading.

[0027] Specifically, in this embodiment, the pressing plate 43 is triangular, and its two ends are located in the installation cavity and are slidably connected to its side walls. A plurality of reinforcing ribs 44 are provided inside the pressing plate 43, and each reinforcing rib 44 is vertically arranged with respect to the bottom of the pressing plate 43. Through this design, the pressing force when the pressing plate presses down is more stable, which is convenient for fixing the pipe, not easy to move, and improves the stability of the long material pipe during the chemical oxidation process.

[0028] Specifically, in this embodiment, the ends of each layer of long material pipes 100 extend beyond the outside of the cushion strips 5 corresponding to their heights, and the extended distance is ≥5 mm to ensure that the long material pipes will not fall off. The specific spacing is adjusted according to actual needs. In addition, the spacing between two adjacent long material pipes 100 in each layer is ≥5 mm. Here, through the design of the cushion strips, the movement of the long material pipes in the upper and lower layers can be avoided, improving the stability of the multi-layer long material pipes during the oxidation process. And each layer of long material pipes is laid flat on the corresponding cushion strips. Through the paving layer by layer, finally, with the downward pressing effect of the pressing plate, the stability of the long material pipes during the oxidation process is greatly improved, and the design of this spacing can improve the finished product rate of the chemical oxidation of the long material pipes.

[0029] In this embodiment, the width of the cushion strip 5 is smaller than the width of the installation cavity. Specifically, the width of the cushion strip 5 can be designed to be 5 mm smaller than the width of the installation cavity, which is convenient for putting the cushion strip into the installation cavity and is not easy to shake left and right, improving the stability of the tooling during use.

[0030] In this embodiment, both the first U-shaped frame 2 and the second U-shaped frame 3 include an inverted funnel-shaped section 111 and a U-shaped section 112 integrally formed from top to bottom. The threaded sleeve 41 is fixed to the inner side of the inverted funnel-shaped section 111, and the cushion strip 5 is arranged on the inner side of the U-shaped section 112. This design makes the overall structure relatively compact and has strong operability.

[0031] In other embodiments, a backing plate is provided between the pressing plate 43 and the long stock pipe 100 at the top layer. This can not only prevent the long stock pipe at the top layer from being damaged and protect the upper surface of the long stock pipe, but also reduce the rotation time of the threaded sleeve by adjusting the thickness of the backing plate, assist the pressing plate in compacting the pipe, and improve the operation efficiency.

[0032] The usage process of the present utility model is as follows:

[0033] First, according to the length of the long stock pipe 100, move the first U-shaped frame 2 and the second U-shaped frame 3 left and right to adjust their positions on the cross bar 1, and then fix the positions of the first U-shaped frame 2 and the second U-shaped frame 3 on the cross bar 1 through fasteners such as bolts and nuts;

[0034] Next, arrange cushion strips of the same height in the inner mounting cavities of the first U-shaped frame 2 and the second U-shaped frame 3, and then lay the long stock pipes at intervals on the cushion strips. After a single layer of pipes is fully laid, then reload a new layer of cushion strips in the inner mounting cavities of the first U-shaped frame 2 and the second U-shaped frame 3, and continue to lay the long stock pipes 100 at intervals on this layer of cushion strips, and perform the loading operation in this way until the specified number of long stock pipes is reached or the rack is full, completing the loading;

[0035] Then, press the two ends of the pipe through the pressing plates on the inner sides of the first U-shaped frame 2 and the second U-shaped frame 3 respectively. Specifically, rotate the threaded sleeve to adjust the downward movement of the pressing plate to press the top layer of pipes, then use fasteners to pass through the locking holes on the two U-shaped frames and align with the locking holes on the threaded sleeve to fix the threaded sleeve, and finally use a crane to lift the entire tooling to the oxidation tank.

[0036] The fixed tooling for chemical oxidation of long stock pipes of the present utility model can meet the usage requirements of long stock pipes of different lengths. Only before loading, move left and right according to the length of the long stock pipe and adjust the positions of the first U-shaped frame and the second U-shaped frame on the cross bar, with a wide application range;

[0037] Moreover, through the design of the cross bar, the first U-shaped frame, the second U-shaped frame and the pressing plate assembly, it can meet the rapid loading requirements and chemical oxidation conditions of long stock pipes of different lengths, with a wide application range. A single operator can also complete the loading of long stock pipes, greatly reducing the labor cost, solving the problem of uneven oxidation caused by aluminum wire bundling in the middle of long stock pipes, reducing the product rejection rate and rework rate, and improving the production flow speed and the finished product rate of long stock pipes.

[0038] By using this tooling, the average time-consuming for loading a single pipe can be controlled within 5 seconds, which greatly saves the loading time, reduces the labor intensity, ensures the loading strength of long pipes, and reduces the trouble of bundling long pipes with aluminum wire in the middle, thereby improving the finished product rate of chemical oxidation of long pipes (the finished product rate after optimization is ≥98%).

[0039] The above-disclosed is only a preferred embodiment of the present invention, and of course, it cannot be used to limit the scope of the rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
