Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder tube blank conveying technology, and specifically discloses a cold-drawn hydraulic cylinder tube blank conveying frame. Background Technology

[0002] Hydraulic cylinder tubes are a type of high-precision steel pipe material produced through cold drawing or hot rolling. Due to their advantages such as no oxide layer on the inner and outer walls, high pressure resistance without leakage, high precision, high surface finish, no deformation after cold bending, and no cracks after flaring or flattening, they are mainly used to produce pneumatic or hydraulic components, such as cylinders or oil cylinders. They can be seamless tubes. During the conveying of hydraulic cylinder tube blanks, a conveyor structure, such as a conveyor frame, is used to transport the blanks.

[0003] Chinese Patent Publication No. CN220843546U discloses a cylinder tube blank conveying rack. The rack includes a frame body with a central cavity containing a mesh. A through cavity is located at the bottom of the frame body, and a storage tray is installed inside the through cavity. A tray cavity is located at the top of the storage tray. Slides are provided on both the front and rear end walls of the top of the frame body. A sliding block is installed at the front end of each slide, and a slider is positioned on the side of the sliding block closest to the slide. A limit bar is installed at the other end of the sliding block. Locking slots are provided on both the left and right end walls of the frame body. This invention uses the displacement of the sliding block and the limit bar to position them at the ends of the frame cavity, thus restraining the cylinder tubes placed inside the cavity and preventing them from rolling out. This ensures the cylinder tubes are stably and safely stored within the frame cavity.

[0004] With the rapid development of technology, the above-mentioned device has the following shortcomings:

[0005] 1. When the above-mentioned device is conveying the cylinder tube blanks, it stacks multiple cylinder tube blanks together. When the device moves, it vibrates and then transmits the vibration effect to the multiple cylinder tube blanks, causing the multiple cylinder tube blanks in the device to collide and damage the outer wall of the cylinder tube blanks.

[0006] 2. When the above-mentioned device is used to unload the cylinder tube blank, one end of the device is opened, and the cylinder tube blank rolls out from one end of the device. During unloading, the cylinder tube blank located at the top will roll down, causing multiple cylinder tube blanks to collide again, further increasing the damage to the outer wall of the cylinder tube blank. Utility Model Content

[0007] This utility model proposes a cold-drawn cylinder tube blank conveying rack. By placing multiple cylinder tube blanks separately, it avoids collisions between multiple cylinder tube blanks due to vibration during movement, which would damage the outer wall of the cylinder tube blanks. It also facilitates the unloading of cylinder tube blanks and prevents secondary damage to the outer wall of the cylinder tube blanks during the unloading process.

[0008] This utility model is implemented as follows: a cold-drawn cylinder tube blank conveying rack includes a base, and a placement mechanism is provided on the upper end surface of the base.

[0009] The placement mechanism includes multiple wave plates that are fixedly connected to the upper surface of the base and evenly distributed on the left and right. The multiple wave plates form multiple placement cylinders with a circular cross-section between adjacent pairs. Each of the multiple placement cylinders is provided with a clamping mechanism inside.

[0010] The clamping mechanism includes a placement plate slidably connected inside the placement cylinder. Two symmetrically distributed clamping plates are slidably connected to the upper end face of the placement plate. An inclined groove is opened on the opposite side wall of the two clamping plates. Two inclined blocks that match the two inclined grooves are fixedly connected to the inner wall of the placement cylinder.

[0011] In a preferred embodiment of the cold-drawn cylinder tube blank conveying frame of this utility model, the inclined surfaces of the two inclined blocks are slidably connected to the inclined surfaces of the two inclined grooves through a first trapezoidal limiting slider and a first trapezoidal limiting groove.

[0012] In a preferred embodiment of the cold-drawn cylinder tube blank conveying frame of this utility model, the lower end faces of the two clamping plates and the upper end face of the placement plate are slidably connected by a second trapezoidal limiting slider and a second trapezoidal limiting groove.

[0013] As a preferred embodiment of the cold-drawn cylinder tube blank conveying frame of this utility model, a return spring is fixedly connected between the upper end face of the base and the lower end face of the placement plate.

[0014] In a preferred embodiment of the cold-drawn cylinder tube blank conveying frame of this utility model, the outer wall of the placement plate and the inner wall of the placement cylinder are slidably connected by a third trapezoidal limiting slider and a third trapezoidal limiting groove.

[0015] As a preferred embodiment of the cold-drawn cylinder tube blank conveying frame of this utility model, silicone pads are provided on the upper end surface of the placement plate and on the opposite side wall of the two clamping plates.

[0016] As a preferred embodiment of the cold-drawn cylinder tube blank conveying frame of this utility model, the lower end face of the base is provided with a plurality of evenly distributed universal wheels with brakes, and the upper end face of the base is fixedly connected with two push rods distributed front and rear.

[0017] The beneficial effects of this utility model are:

[0018] Multiple placement cylinders formed by multiple corrugated plates can be used to place multiple cylinder tube blanks individually, avoiding collisions between the cylinder tube blanks due to vibration during movement, preventing damage to the outer wall of the cylinder tube blanks, and clamping and fixing the cylinder tube blanks through a clamping mechanism, further improving the placement stability of the cylinder tube blanks.

[0019] The cylinder tube blank is lifted upward by the upper end, and the clamping mechanism is released from the clamping and fixing state of the cylinder tube blank. Then the cylinder tube blank is taken out from the placement cylinder, which facilitates the unloading of the cylinder tube blank and prevents secondary damage to the outer wall of the cylinder tube blank during the unloading process.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0027] Please see Figure 1-4A cold-drawn cylinder tube blank conveying frame includes a base 1, and a placement mechanism is provided on the upper end surface of the base 1.

[0028] The placement mechanism includes multiple wave plates 2 that are fixedly connected to the upper surface of the base 1 and are evenly distributed on the left and right. The multiple wave plates 2 form multiple placement cylinders 3 with circular cross-sections between adjacent pairs. Each of the multiple placement cylinders 3 is equipped with a clamping mechanism.

[0029] The clamping mechanism includes a placement plate 4 slidably connected inside the placement cylinder 3. Two symmetrically distributed clamping plates 5 are slidably connected to the upper end face of the placement plate 4. An inclined groove 6 is provided on the opposite side wall of the two clamping plates 5. Two inclined blocks 7 that match the two inclined grooves 6 are fixedly connected to the inner wall of the placement cylinder 3.

[0030] In this embodiment: when placing the cylinder tube blanks, multiple cylinder tube blanks are vertically placed into multiple placement cylinders 3 in sequence. The placement cylinders 3, formed by multiple corrugated plates 2, allow for individual placement of the cylinder tube blanks, preventing collisions due to vibration during movement and protecting the outer walls of the blanks. A clamping mechanism further secures the cylinder tube blanks, improving their placement stability. Specifically, when the cylinder tube blanks enter the placement cylinders 3, their lower ends first contact the placement plates 4, and then... The weight of the blank itself presses the placement plate 4 downward. As the placement plate 4 moves downward, it drives the two clamping plates 5 to move downward through the cooperation between the second trapezoidal limiting slider 10 and the second trapezoidal limiting groove 11. At the same time, through the cooperation between the two inclined grooves 6 and the two inclined blocks 7, the two clamping plates 5 are pushed to move in opposite directions, so that the two clamping plates 5 abut against the outer wall of the cylinder tube blank, thereby clamping and fixing the cylinder tube blank. Then, the base 1 is pushed to move through multiple casters 15 and two push rods 16, thereby transporting the cylinder tube blank.

[0031] When unloading the cylinder tube blank, the upper end of the cylinder tube blank is lifted upwards. At the same time, the return spring 12 rebounds, pushing the placement plate 4 upwards. The placement plate 4 drives the two clamping plates 5 upwards. Since the inclined surfaces of the two inclined blocks 7 are slidably connected to the inclined surfaces of the two inclined grooves 6 through the first trapezoidal limiting slider 8 and the first trapezoidal limiting groove 9, when the two clamping plates 5 move upwards, the mutual cooperation between the first trapezoidal limiting slider 8 and the first trapezoidal limiting groove 9 can drive the two clamping plates 5 to move in opposite directions, thereby releasing the clamping and fixing state of the cylinder tube blank. Then, the cylinder tube blank is taken out from the placement cylinder 3, which facilitates the unloading of the cylinder tube blank and prevents secondary damage to the outer wall of the cylinder tube blank during the unloading process.

[0032] As a technical optimization of this utility model, the inclined surfaces of the two inclined blocks 7 are slidably connected to the inclined surfaces of the two inclined grooves 6 through the first trapezoidal limiting slider 8 and the first trapezoidal limiting groove 9.

[0033] In this embodiment, the cooperation between the first trapezoidal limiting slider 8 and the first trapezoidal limiting groove 9 can drive the two clamping plates 5 to move in opposite directions.

[0034] As a technical optimization of this utility model, the lower end surfaces of the two clamping plates 5 and the upper end surface of the placement plate 4 are slidably connected by the second trapezoidal limiting slider 10 and the second trapezoidal limiting groove 11.

[0035] In this embodiment, the cooperation between the second trapezoidal limiting slider 10 and the second trapezoidal limiting groove 11 enables the two clamping plates 5 to move smoothly while simultaneously moving the two clamping plates 5.

[0036] As a technical optimization of this utility model, a return spring 12 is fixedly connected between the upper end face of the base 1 and the lower end face of the placement plate 4.

[0037] In this embodiment, the placement plate 4 can be reset by the reset spring 12.

[0038] As a technical optimization of this utility model, the outer wall of the placement plate 4 and the inner wall of the placement cylinder 3 are slidably connected by the third trapezoidal limiting slider 13 and the third trapezoidal limiting groove 14.

[0039] In this embodiment, the placement plate 4 can be limited by the cooperation between the third trapezoidal limiting slider 13 and the third trapezoidal limiting groove 14, so that the placement plate 4 can move smoothly.

[0040] As a technical optimization of this utility model, silicone pads are provided on the upper end surface of the placement plate 4 and the opposite side wall of the two clamping plates 5.

[0041] In this embodiment, the silicone pad can further protect the outer wall of the cylinder tube blank.

[0042] As a technical optimization of this utility model, the lower end face of the base 1 is provided with a plurality of evenly distributed universal wheels 15 with brakes, and the upper end face of the base 1 is fixedly connected with two push rods 16 distributed front and back.

[0043] In this embodiment, the base 1 can be moved by the cooperation between multiple casters 15 and two push rods 16, thereby transporting the cylinder tube blank.

[0044] The working principle and usage process of this utility model are as follows: When placing cylinder tube blanks, multiple cylinder tube blanks are placed vertically into multiple placement cylinders 3 in sequence. When the cylinder tube blanks enter the placement cylinders 3, the lower end of the cylinder tube blanks first contacts the placement plate 4. Then, the weight of the cylinder tube blanks themselves presses the placement plate 4 downward. While the placement plate 4 moves downward, the placement plate 4 drives the two clamping plates 5 to move downward through the mutual cooperation between the second trapezoidal limiting slider 10 and the second trapezoidal limiting groove 11. At the same time, through the mutual cooperation between the two inclined grooves 6 and the two inclined blocks 7, the two clamping plates 5 are pushed to move in opposite directions, so that the two clamping plates 5 abut against the outer wall of the cylinder tube blanks, thereby clamping and fixing the cylinder tube blanks. Then, the base 1 is moved by multiple universal wheels 15 and two push rods 16, thereby transporting the cylinder tube blanks.

[0045] When unloading the cylinder tube blank, the upper end of the cylinder tube blank is lifted upwards. At the same time, the return spring 12 rebounds, pushing the placement plate 4 upwards. The placement plate 4 drives the two clamping plates 5 upwards. Since the inclined surfaces of the two inclined blocks 7 are slidably connected to the inclined surfaces of the two inclined grooves 6 through the first trapezoidal limiting slider 8 and the first trapezoidal limiting groove 9, when the two clamping plates 5 move upwards, the mutual cooperation between the first trapezoidal limiting slider 8 and the first trapezoidal limiting groove 9 can drive the two clamping plates 5 to move in opposite directions, thereby releasing the clamping and fixing state of the cylinder tube blank, and then taking the cylinder tube blank out of the placement cylinder 3.

Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
