Description

Technical Field

[0001] This utility model relates to the field of cold drawing machine technology, and in particular to a cold drawing machine material receiving and pushing tube device. Background Technology

[0002] Cold drawing is a metal cold treatment method that involves clamping the end of a metal tube with a clamping trolley mounted on the cold drawing machine body, and then pulling it out under the reverse traction of the clamping trolley, thereby extending the length of the metal tube.

[0003] After the drawing process, the clamps of the clamping trolley release their grip on the metal tube, allowing the metal tube to fall onto the machine body at the drawing station, and then slide down the slide rail onto the material rack for stacking.

[0004] However, due to the long length of the metal tube, support rods are usually installed at intervals along the length of the cold drawing machine to prevent the metal tube from bending. After the metal tube is arranged on the support rods, it is pushed down onto the slide by manual or mechanical means.

[0005] In the existing material collection method, these support rods are generally fixedly installed on the body of the cold drawing machine. When the cold-drawn metal tubes fall from the clamps onto the machine body, the alignment of the metal tubes on the machine body is not ideal, and there is a skewed phenomenon. This requires manual processing to straighten some skewed metal tubes to facilitate material collection. This increases the workload, the degree of automation of cold drawing operations is not high, and the work efficiency is reduced. Summary of the Invention

[0006] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides a cold drawing machine receiving and pushing device that can ensure the neat arrangement of metal tubes after forming and improve the automation level of cold drawing operation.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a cold drawing machine receiving and pushing tube device, wherein the cold drawing machine has a cold drawing bed, a feeding platform is provided on the rear side of the cold drawing bed, and at least three receiving racks are provided on the front side of the cold drawing bed at intervals along the length direction of the cold drawing bed. Guide tubes are fixed on the feeding platform at intervals along the length direction of the cold drawing bed and corresponding to the positions of the receiving racks. The guide tubes are perpendicular to the length direction of the cold drawing bed. A receiving arm that can move to the top of the cold drawing bed to receive the cold-drawn metal tube is provided in the guide tube. A pushing arm that pushes the metal tube on the receiving arm to the receiving rack is provided above the receiving arm.

[0008] Specifically, the guide tube includes a receiving guide tube fixed on the loading platform, a receiving arm slidably disposed inside the receiving guide tube, and a pushing guide tube superimposed and fixed on the receiving guide tube, the pushing arm being slidably disposed inside the pushing guide tube.

[0009] Preferably, a receiving cylinder is provided on the outer wall of the receiving conduit, and the piston rod of the receiving cylinder is connected to the front end of the receiving arm extending out of the receiving conduit; a pushing cylinder is provided on the outer wall of the pushing conduit, and the piston rod of the pushing cylinder is connected to the front end of the pushing arm extending out of the pushing conduit.

[0010] To make the feeding process more stable, a feeding top block is fixed at the top of the front end of the feeding arm.

[0011] Furthermore, a protective plate is fixed to the upper end face of the receiving arm, and the front end of the protective plate has an inclined surface that slopes towards the receiving rack. The inclined surface makes it easier for the metal tube on the receiving arm to be pushed down onto the receiving rack.

[0012] To facilitate the stacking of the pushed-down metal tubes, the receiving rack includes a receiving trough. A guide plate is fixed between the upper end of the receiving trough and the inner bottom surface near the side of the cold drawing machine. The upper end of the guide plate is flush with the bottom surface of the pusher arm.

[0013] The beneficial effects of this utility model are: This utility model adopts a receiving arm that moves above the cold drawing bed to receive the cold-drawn metal tube, and a pusher arm pushes the metal tube into the receiving rack for collection. In this way, even if the metal tube is not neatly arranged, there is no need for manual processing, thereby reducing the amount of cold drawing work and improving the automation and efficiency of cold drawing work.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] like Figures 1-3 The diagram illustrates a material receiving and pushing device for a cold drawing machine. The cold drawing machine has a cold drawing bed 1, a feeding platform 2 located at the rear of the cold drawing bed 1, and six receiving racks 3 spaced apart along the length of the cold drawing bed 1 located at the front of the cold drawing bed 1. Only three receiving racks 3 are shown in the attached diagram.

[0022] The loading platform 2 is fixed with six sets of guide tubes spaced apart along the length of the cold drawing bed 1. Each set of guide tubes corresponds to a receiving rack 3, and the axis of the guide tube is perpendicular to the length of the cold drawing bed 1. The guide tube includes a receiving guide tube 6 and a pushing guide tube 7. The bottom of the front and rear ends of the receiving guide tube 6 is fixed to the loading platform 2 by welding plates. The pushing guide tube 7 is stacked and fixed on the upper end face of the receiving guide tube 6. A receiving arm 4 is slidably provided in the receiving guide tube 6. A protective plate 11 of the same length as the receiving arm 4 is fixed on the upper end face of the receiving arm 4. A pushing arm 5 is slidably provided in the pushing guide tube 7. A pushing top block 10 is fixed at the front end of the pushing arm 5.

[0023] The receiving conduit 6 is provided with a receiving cylinder 8 on its outer side wall. A rear hinge shaft is fixed to the rear end of the outer side wall of the receiving conduit 6. A front hinge shaft is fixed to the front side of the receiving arm 4 extending out of the receiving conduit 6. The support at the rear end of the receiving cylinder 8 is hinged to the rear hinge shaft. The piston rod end of the receiving cylinder 8 is connected to the front hinge shaft through a cylinder connector.

[0024] The outer wall of the pusher guide 7 is provided with a pusher cylinder 9. A rear hinge shaft is fixed to the rear end of the outer wall of the pusher guide 7. A front hinge shaft is fixed to the front side of the pusher arm 5 extending out of the pusher guide 7. The support at the rear end of the pusher cylinder 9 is hinged to the rear hinge shaft. The piston rod end of the pusher cylinder 9 is connected to the front hinge shaft through a cylinder connector.

[0025] like Figure 4 As shown, the receiving rack 3 includes a receiving trough 3-1. A guide inclined plate 3-2 is fixed between the upper end of the receiving trough 3-1 near the cold drawing bed 1 and its inner bottom surface. The upper end of the guide inclined plate 3-2 is flush with the bottom surface of the pusher arm 5. The front end of the protective plate 11 has an inclined surface 11-1 that is inclined towards the guide inclined plate 3-2 of the receiving rack 3.

[0026] After the clamping trolley of the cold drawing machine completes the cold drawing of the metal tube by pulling it in the reverse direction, the receiving cylinder 8 is activated, pushing the six receiving arms 4 to move synchronously above the cold drawing bed 1. The clamping trolley releases its grip on the formed metal tube, and the metal tube falls onto the receiving arm 4. Then the pushing cylinder 9 is activated, pushing the pushing arm 5 to move and push the metal tube received on the receiving arm 4 to the upper end of the guide inclined plate 3-2 of the receiving rack 3. The metal tube slides down the guide inclined plate 3-2 and accumulates on the inner bottom surface of the receiving rack 3, thus completing the receiving of the cold-drawn metal tube.

[0027] This utility model employs a receiving arm 4 to receive the cold-drawn metal tube, and a pushing arm 5 to push the metal tube into a receiving rack 3 for collection. In this way, even if the metal tubes are not neatly arranged, no manual processing is required, which improves the automation level of the cold drawing operation, reduces the amount of cold drawing work, and improves work efficiency.
