Description

Technical Field

[0001] This utility model belongs to the field of tooth pressing mold technology, and in particular relates to a tooth pressing mold for the side of a square tube of a template clamp. Background Technology

[0002] In the splicing of square tubes in building steel structures, such as scaffolding and truss connections, it is necessary to press teeth on the outer surface of the rectangular square tubes. When in contact with other components, the toothed structure can increase friction or achieve interlocking and form a mechanical interlock to prevent relative sliding or falling off.

[0003] In existing technologies, this tooth shape can be achieved through laser cutting or machining drilling, but this method is too costly for mass production and is not conducive to cost reduction. Summary of the Invention

[0004] The purpose of this utility model embodiment is to provide a square tube side pressing tooth mold for template clamping, which aims to solve the technical problem that pressing tooth shape on the outer side of square tube is done by laser cutting or machining drilling, but this method is too costly for mass production and is not conducive to cost reduction.

[0005] The present invention is implemented as follows:

[0006] A square tube side-mounted tooth pressing mold for a template clamp includes a square tube fixing seat fixed to the top of a lower template. The square tube fixing seat has toothed holes on both sides. A pair of punches are symmetrically arranged on both sides of the square tube fixing seat. The punches cooperate with the toothed holes to achieve tooth pressing. The punches are connected to a second inclined block slidably connected to the lower template. The second inclined block is connected to the bottom of a first inclined block through an inclined surface. The first inclined block is fixedly connected to the end of an upper template. The upper template is movably connected to the lower template through a guide post. When the upper template moves up and down, the upper template drives the first inclined block, which in turn drives the second inclined block to move back and forth in the horizontal direction, thereby causing the punches to cooperate with or separate from the toothed holes.

[0007] Furthermore, the lower template has a vertical plate in the middle, and the vertical plate is fixedly connected to the connecting plate of the square tube fixing seat by bolts.

[0008] Furthermore, the square tube fixing seat has a rectangular cross-section and arc-shaped mold core surfaces on both sides. The mold core surfaces have limiting surfaces on both sides. The mold core surfaces are evenly provided with a number of toothed holes along the axial direction of the square tube fixing seat. The shape of the toothed holes matches the shape of the toothed pressure head in the punch. The center of the square tube fixing seat is a discharge hole with an elliptical or rectangular cross-section. The central discharge hole of the toothed hole penetrates the wall of the square tube fixing seat and is connected to the discharge hole.

[0009] Furthermore, the punch includes a toothed pressure head that mates with the toothed hole, and the top and bottom of the toothed pressure head are provided with clearance steps.

[0010] Furthermore, the second inclined block is slidably disposed on the top surface of the first support seat via a guide plate, and the first support seat is fixed to the top surface of the lower template; the second inclined block and the second inclined block are two sets, symmetrically disposed on both sides of the square tube fixing seat.

[0011] Furthermore, a pushing block is fixed to the side of the second inclined block. The side of the pushing block is provided with a pushing surface. When pressing the teeth, the pushing surface contacts the back of the punch of the punch and pushes the punch to press the teeth.

[0012] Furthermore, the second inclined block has a blind hole in the middle, and a punching rod is provided in the blind hole. The punching rod passes through the push block and the punch and is located at the center of the toothed pressure head, for punching out the required through hole in the middle of the tooth.

[0013] The advantages of this invention are: by fitting a square tube onto the outside of a square tube fixing seat, when the upper template drives the first inclined block, which in turn drives the second inclined block to reciprocate horizontally, the punch engages or disengages with the toothed hole, thus achieving toothed pressing on the outside of the square tube. The toothed hole of the square tube fixing seat provides support during pressing, ensuring the tooth shape while preventing deformation of the square tube. When unilateral tooth pressing is required, only one side of the punch needs to be removed. Therefore, this invention also has the function of simultaneously pressing teeth on both sides or performing unilateral tooth pressing. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] like Figure 1 Only Figure 5 The diagram shows the structure of a square tube side-mounted tooth pressing mold provided in an embodiment of this utility model. The square tube side-mounted tooth pressing mold includes a square tube fixing seat 1 fixed to the top of the lower template 4. The square tube fixing seat 1 has toothed holes 102 on both sides. A pair of punches 2 are symmetrically arranged on both sides of the square tube fixing seat 1. The punches 2 cooperate with the toothed holes 102 to achieve tooth pressing. The punches 2 are connected to a second inclined block 7 slidably connected to the lower template 4. The second inclined block 7 is connected to the bottom of the first inclined block 10 through an inclined surface. The first inclined block 10 is fixedly connected to the end of the upper template 12. The upper template 12 is movably connected to the lower template 4 through a guide post 13. When the upper template 12 moves up and down, the upper template 12 drives the first inclined block 10, which drives the second inclined block 7 to move back and forth in the horizontal direction, thereby driving the punches 2 to cooperate or separate from the toothed holes 102.

[0024] In this embodiment of the invention, by fitting a square tube onto the outside of a square tube fixing seat, when the upper template drives the first inclined block, which in turn drives the second inclined block to reciprocate horizontally, thereby causing the punch to engage or disengage with the toothed hole, toothed pressing is achieved on the outside of the square tube. The toothed hole of the square tube fixing seat provides support during pressing, ensuring the tooth shape while preventing deformation of the square tube. When unilateral tooth pressing is required, only one side of the punch needs to be removed. Therefore, this invention also has the function of pressing teeth on both sides simultaneously or performing unilateral tooth pressing.

[0025] Specifically, such as Figure 1 Only Figure 5 As shown, a square tube side-mounted tooth pressing mold for a template clamp includes a square tube fixing seat 1 fixed to the top of the lower template 4. The square tube fixing seat 1 has toothed holes 102 on both sides. A pair of punches 2 are symmetrically arranged on both sides of the square tube fixing seat 1. The punches 2 cooperate with the toothed holes 102 to achieve tooth pressing. The punches 2 are connected to a second inclined block 7 slidably connected to the lower template 4. The second inclined block 7 is connected to the bottom of the first inclined block 10 through an inclined surface. The first inclined block 10 is fixedly connected to the end of the upper template 12. The upper template 12 is movably connected to the lower template 4 through a guide post 13. When the upper template 12 moves up and down, the upper template 12 drives the first inclined block 10, which drives the second inclined block 7 to move back and forth in the horizontal direction, thereby driving the punches 2 to cooperate or separate from the toothed holes 102.

[0026] The lower template 4 has a vertical plate in the middle, which is fixedly connected to the connecting plate 105 of the square tube fixing seat 1 by bolts. The square tube fixing seat 1 has a rectangular cross-section and arc-shaped mold core surfaces on both sides. The two sides of the mold core surface are limiting surfaces 101. The point farthest from the center of the square tube fixing seat 1 is in the same plane as the two edges on the same side of the square tube fixing seat 1, that is, it is flush with the limiting surface 101. The mold core surface is evenly provided with a number of toothed holes 102 along the axial direction of the square tube fixing seat 1. The shape of the toothed holes 102 matches the shape of the toothed pressure head 201 in the punch 2. The center of the square tube fixing seat is a discharge hole with an elliptical or rectangular cross-section. The central discharge hole of the toothed hole 102 penetrates the wall of the square tube fixing seat 1 and is connected to the discharge hole.

[0027] The punch 2 includes a toothed pressure head 201 that mates with the toothed hole 102. The top and bottom of the toothed pressure head 201 are provided with clearance steps 202 to avoid the limiting surface 101, so as to prevent the toothed hole 102 and the toothed pressure head 201 from not being fully fitted when pressing the toothed shape.

[0028] The second inclined block 7 is slidably mounted on the top surface of the first support seat 5 via the guide plate 3. The first support seat 5 is fixed to the top surface of the lower template. This structure consists of two sets, symmetrically arranged on both sides of the square tube fixing seat 1.

[0029] The second inclined block 7 has a push block 3 fixed on its side. The push block has a push surface 301 on its side. When pressing the teeth, the push surface 301 contacts the back surface 203 of the punch 2, pushing the punch 2 to press the teeth.

[0030] The second inclined block 7 has a blind hole in the middle, and a punching rod 302 is provided in the blind hole. The punching rod 302 passes through the push block 3 and the punch 2 and is located at the center of the toothed pressure head 201, and is used to punch out the required through hole in the middle of the tooth.

[0031] The top of the first inclined block 10 is fixedly connected to the upper template 12 by a rectangular boss. The first inclined block 10 has an inclined surface. The first inclined block 10 pushes the second inclined block 7 to move by cooperating with the inclined surface of the second inclined block 7. The back of the inclined surface of the first inclined block 10 slides in contact with the adjustment plate 9. The adjustment plate 9 is fixed inside the second support seat 8. The second support seat 8 is fixed to the top surface of the lower template 4.

[0032] The upper template 12 is provided with a guide sleeve 1301, and the guide post 13 is inserted in the guide sleeve 1301. The upper template 12 is movably connected to the lower template 4 by sliding the guide post 13 in the guide sleeve.
