Description

Technical Field

[0001] The utility model relates to the technical field related to U-shaped steel, in particular to a U-shaped steel cutting knife mould. Background Art

[0002] U-shaped steel is a common steel model with many unique characteristics and wide applications. Whether in construction, automobile manufacturing, mechanical processing or other fields, U-shaped steel plays an important role. When processing U-shaped steel, in order to produce U-shaped steel of different lengths, the U-shaped steel will be cut. There is currently a U-shaped steel cutting knife mold (application number: 201721061513.9) which sets a feeding component and a discharging component, and through the cooperation of the feeding component and the discharging component, the cutter can better find the cutting point, can quickly cut the U-shaped steel, and improve the production efficiency of the enterprise. At the same time, the structure of the mold is simple and the maintenance cost is low; by making the width and height of the through hole a of the feeding component smaller than the width and height of the through hole b of the discharging component, burrs are generated during the cutting process of the U-shaped steel, and the burrs affect the discharging of the product. This setting can make the product discharge smoothly and ensure the working efficiency of the cutting.

[0003] The above problem still exists. When the U-shaped steel is moved and guided by the feed assembly and the discharge assembly, although the movement stability of the U-shaped steel during the cutting process can be guaranteed, the hole size processed at the feed assembly and the discharge assembly cannot be changed. It may be inconvenient for U-shaped steels of different specifications to move in the holes of the feed assembly and the discharge assembly. At the same time, the U-shaped steel may move due to friction in the hole, which may cause wear and noise during processing. Utility Model Content

[0013] The beneficial effects of the utility model are:

[0014] 1. The U-shaped steel is placed on the multiple sets of round rods through the cooperation among the first push rod, the frame, the roller, the sliding rod, the sliding sleeve, the spring, the rod body, the plate body and the ball bearings. At the same time, the first push rod is used to drive the roller to move downward, so that the roller can penetrate into the U-shaped steel and fit with the inner wall of the U-shaped steel, so that the U-shaped steel can be fixedly transported. At the same time, when the roller fits with the U-shaped steel, the ball bearings on both sides will contact with the outer walls on both sides of the U-shaped steel, and then the ball bearings on both sides will be squeezed by the outer walls on both sides of the U-shaped steel and fit with the inner walls on both sides of the U-shaped steel, so that the U-shaped steel can be stably transported without generating large noise and wear.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1, reference Figures 1 to 5 A U-shaped steel cutting knife mold includes a frame 1, a first push rod 2 is installed on the frame 1, a frame 3 is installed on the output end of the first push rod 2, the first push rod 2 can drive the frame 3 to move up and down, the frame 3 is connected to multiple groups of rollers 4 through a connecting shaft, the rollers 4 are used to fit the bottom end of the inner wall of the U-shaped steel, a sliding rod 5 is fixed to the top of the frame 3, the outer wall of the sliding rod 5 is slidably connected to two groups of sliding sleeves 6, the sliding sleeves 6 can slide horizontally on the outer wall of the sliding rod 5, the two groups of sliding sleeves 6 are rotatably connected to two groups of rod bodies 8 through a connecting shaft, and each two groups of rod bodies 8 are respectively connected to two groups of plate bodies through a connecting shaft 9 is rotatably connected. When the plate body 9 moves horizontally, the plate body 9 can drive the two groups of rod bodies 8 to move synchronously, and then drive the two groups of sliding sleeves 6 to slide on the outer wall of the sliding rod 5 one after the other. There are multiple groups of balls 10 movably connected on the two groups of plate bodies 9, and the frame body 1 is rotatably connected to multiple groups of round rods 14 through bearings. The round rods 14 and the rollers 4 are clamped and fitted with the two ends of the U-shaped steel, and the balls 10 on both sides are fitted with the two sides of the inner wall of the U-shaped steel, so that the U-shaped steel can be stably moved and then cut off without generating loud noise or friction to cause wear on the U-shaped steel.

[0024] In this embodiment, a second push rod 11 is installed on the frame 1, and the second push rod 11 can drive the cutter 12 to move up and down. The cutter 12 is installed on the output end of the second push rod 11, and a grinding plate 13 is installed on the cutter 12. The grinding plate 13 is used to grind the cut part of the U-shaped steel. The outer wall of the slide bar 5 is slidably connected with two groups of springs 7. One end of the two groups of springs 7 is fixed to the slide bar 5. The spring 7 gives the two groups of plate bodies 9 to drive multiple groups of balls 10, which are respectively tightly fitted with the two ends of the inner wall of the U-shaped steel. The other ends of the two groups of springs 7 are respectively fixed to the two groups of sliding sleeves 6. The outer walls of the multiple groups of round rods 14 are fixed with rubber sleeves 15. The rubber The sleeve 15 is used to increase the contact friction between the round rod 14 and the U-shaped steel. A slide rail 16 is fixed to the frame 3. The slide rail 16 is slidably connected to the two sets of slide sleeves 6. The slide rail 16 is used to guide the lateral movement of the slide sleeve 6, thereby improving the stability of the lateral movement of the plate body 9. The front and rear end faces of the frame 1 are both open, so that the U-shaped steel shell enters the front end face of the frame 1 and moves out of the rear end face. There is space between the round rod 14 and the bottom end of the inner wall of the frame 1, so that if debris falls between the round rods 14 and the round rods 14, when the debris falls on the bottom end of the inner wall of the frame 1, it can also be taken out and cleaned in the space between the frame 1 and the round rod 14.

[0025] The working principle of this embodiment is as follows: when in use, the U-shaped steel is placed on the multiple groups of round rods 14 at the frame 1. At the same time, the first push rod 2 drives the frame 3 to move downward, and the frame 3 can drive the multiple groups of rollers 4 to penetrate into the U-shaped steel and fit with the bottom end of the inner wall of the U-shaped steel. After fitting, since the rollers 4 and the round rods 14 fit with one end and the other end of the U-shaped steel respectively, the U-shaped steel can be fixedly placed in the frame 1. When the rollers 4 contact the U-shaped steel, the multiple groups of balls 10 on the plates 9 on both sides of the frame 3 will contact the outer walls on both sides of the U-shaped steel respectively. At this time, due to the rotation of the balls 10 and the lateral movement of the sliding sleeve 6 on the outer wall of the sliding rod 5, the U-shaped steel can be used to move downward. The squeezing force of the ball 10 drives the plate 9 to move toward one end of the frame 3, and then move into the U-shaped steel and fit with both sides of the inner wall of the U-shaped steel. At this time, the U-shaped steel is moved in the frame 1, and the rotation of the round rod 14, the roller 4 and the ball 10 can ensure the stable lateral movement of the U-shaped steel. When the U-shaped steel moves below the cutter 12, the second push rod 11 drives the cutter 12 to move downward, and the cutter 12 can cut the U-shaped steel. When the cutter 12 moves downward during cutting, the grinding plate 13 at the cutter 12 will grind and deburr the incision at the cut of the U-shaped steel, thereby improving the finished product effect of the U-shaped steel processing.
