Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, for the utility model discloses a convenient to use's panel beating stamping die, including frame 1 and vertical cope match-plate pattern 2, lower bolster 3 and the base 4 of setting in order on frame 1. The base 4 is fixed with a plurality of sliding cylinders 41 with vertical axes, and the bottom surface of the lower template 3 is fixed with a sliding rod 31 which is inserted into the sliding cylinders 41 and is connected with the sliding cylinders 41 in a sliding manner. A hydraulic element 11 for driving the upper template 2 to move up and down is fixed on the frame 1, and a plurality of supporting springs 5 are arranged between the base 4 and the lower template 3. Referring to fig. 3 and 4, bases 51 are fixed at both ends of the supporting spring 5, a limiting rod 53 and a limiting cylinder 54 with coincident axes are respectively fixed on the opposite surfaces of the two bases 51, and the limiting rod 53 and the limiting cylinder 54 are connected in a sliding manner vertically. The base 51 is connected with the mounting seat 52 in a rotating mode on the end face far away from the supporting spring 5, the rotating axis of the mounting seat 52 is overlapped with the axis of the limiting rod 53, and the end portions, far away from each other, of the two mounting seats 52 are respectively connected with the lower template 3 and the base 4 in a threaded mode.

The support springs 5 provide elastic buffer force when the user drives the upper die plate 2 to move downwards through the hydraulic component 11 and presses the lower die plate 3. When the supporting spring 5 is lowered due to long-term use, the user rotates the mounting seat 52 to separate the mounting seat 52 from the corresponding base 4 and the lower template 3, thereby replacing the supporting spring 5 with a new one. Due to the self-locking property of the threads, the mounting seat 52 cannot be separated from the corresponding base 4 and the lower template 3 when the supporting spring 5 is buffered vertically, the rebound direction of the supporting spring 5 is guided by the sliding connection of the limiting rod 53 and the limiting cylinder 54, and the buffering effect is good. The stable buffering of stamping process is realized through convenient dismouting nature of supporting spring 5, long service life, convenient to use.

Referring to fig. 3, in order to enhance the fixing stability of the mounting seat 52, a magnetic sheet 521 is fixed on the end surface of the mounting seat 52 away from the base 51, and the magnets 34 are fixed on the lower mold plate 3 and the base 4 corresponding to the magnetic sheet 521. When the mount 52 is screwed to the corresponding lower die plate 3 and base 4 in a normal state, the magnetic sheet 521 and the magnet 34 abut against each other and the magnetic force attracts each other. The magnetic force of the magnetic sheet 521 and the magnet 34 attracting each other further enhances the stability of the fixed connection between the mounting seat 52 and the corresponding lower template 3 and the base 4, and the elastic buffer is more stable.

Referring to fig. 3, in order to prolong the service life of the supporting spring 5, the opposite end surfaces of the base 51 and the mounting seat 52 are coated with wear-resistant paint layers 55 made of epoxy resin and the like, so that the base 51 and the mounting seat 52 are not easy to wear when rotating relatively, are not easy to wear when being pressed against each other, and have long service life.

Referring to fig. 5, for further buffering, a waist-shaped hole 411 horizontally penetrating through the sliding barrel 41 is formed in the sliding barrel 41, and a stroke rod 311 with a horizontal axis is screwed on the sliding rod 31. Both ends of the stroke rod 311 penetrate through the waist-shaped hole 411 and abut against the waist-shaped hole 411, and a rubber ring 412 is fixed on the inner wall of the waist-shaped hole 411. When the lower mold plate 3 moves up and down, the engagement of the stroke rod 311 with the waist-shaped hole 411 limits the moving stroke of the lower mold plate 3. The elasticity of the rubber ring 412 prevents the two ends of the stroke rod 311 and the waist-shaped hole 411 from being abraded when impacting each other, and the shock absorption and buffering effects are better. And the sliding structure can be disassembled, so that the lower template 3 is convenient to replace and the use is convenient.

Referring to fig. 1 and 6, for further buffering, guide cylinders 32 with vertical axes are fixed on the lower die plate 3, guide rods 21 inserted into the guide cylinders 32 are fixed on the bottom surface of the upper die plate 2, the number of the guide cylinders 32 is several, and the number of the guide cylinders 32 is equal to that of the guide rods 21. The outer circumferential surfaces of the guide rod 21 and the guide cylinder 32 are respectively provided with a damping ring 6 made of elastic materials in a sleeved mode, and the two damping rings 6 are mutually abutted when the upper template 2 and the lower template 3 are abutted and compressed. Referring to fig. 7, the guide rod 21 and the guide cylinder 32 are provided with annular grooves 61 on their outer circumferential surfaces, the annular grooves 61 have a trapezoidal cross-sectional shape with short bottom edges close to the outside of the openings of the annular grooves 61, and the inner sides of the damper rings 6 are fitted into the annular grooves 61.

The two damping rings 6 are buffered by resilience force of mutual extrusion in the stamping process, and when the elastic force is declined after long-term use, a user can manually separate the embedding groove from the damping rings 6 and reversely operate to fix the new damping rings 6 on the corresponding guide rods 21 and guide cylinders 32. The convenient person of installing and uninstalling of damping ring 6 changes damping ring 6, conveniently keeps the effect of shock attenuation buffering, convenient to use.

Referring to fig. 1 and 8, in order to ensure the punching quality, a plurality of positioning pins 22 with vertical axes are fixed on the bottom surface of the upper template 2, and positioning holes 33 are arranged on the top surface of the lower template 3 corresponding to the positioning pins 22. When the upper die plate 2 is abutted and pressed against the lower die plate 3, the positioning pin 22 is inserted into the positioning hole 33, the depth of the positioning hole 33 is slightly larger than the height of the positioning pin 22, and referring to fig. 9, a sponge block 331 is placed in the positioning hole 33. The sponge block 331 is arranged in a frustum shape with the top surface area smaller than the bottom surface area, and the sponge block 331 is filled with lubricating oil and is in a compressed state when being abutted against the positioning pin 22. The user can fix a position through the embedding of locating pin 22 and locating hole 33, and locating pin 22 inserts and extrudes sponge piece 331 and is stained with lubricating oil in locating hole 33, and automatic lubrication is difficult for wearing and tearing at the in-process of plug, and the location is accurate. And the shape of the sponge block 331 is convenient for a user to clamp the sponge block 331 and take out the sponge block 331 from the positioning hole 33 by using tools such as tweezers, so that the sponge block 331 is convenient to replace and convenient to use.

The implementation principle of the embodiment is as follows: the user absorbs shock and buffers in the stamping process through the elasticity of the supporting spring 5 and the rubber ring 412, and screws off the mounting seat 52 when the elastic force of the supporting spring 5 is reduced due to long-term use, and connects the mounting seat 52 of the new supporting spring 5 with the corresponding base 4 and the lower template 3 in a threaded manner. The supporting spring 5 is convenient to replace, the damping and buffering effects are stable, and the use is convenient.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
